▼ Living in extreme climatic conditions is challenging on planet Earth which encourages researchers hoping to find life on other planets such as Mars. This research was conducted to explore the effects on human behavior and willingness to go to Mars when individuals were informed about all the possible risks. Two studies were conducted to examine the participants. First, through an online survey and second through observation study on the participants who participated in a habitat study in the LUNARES facility in Poland.
As per reviewed literature, there are thousands of people who have already shown their interest to go to Mars. Since the technology is under development to send humans to Mars, researchers are making sure of the safest journey for the astronauts. It is imperative to select the right candidates among all these thousands of interested people. This study was helpful to review the physiological effects that crew face in isolation, to find out the solutions before any long-duration space mission, and to satisfy the hypothesis. There were 157 participants who participated in the survey, and 36 participated in the habitat observation study. Researcher expected that most of the participants are not fully aware of the risks they may encounter in space. Once participants are aware, many are likely to decline the mission. The results from the daily diary questionnaire study convey that even though the participants stayed in isolation for a short period, participants still showed some symptoms of isolation such as loneliness, boredom, fatigue. Results also show that different age groups have a different mindset and motivation for the Mars mission. Results show some significant difference in the comparison study of participants < 30 and 30+ age group, such as < 30 age group participants show more interest in the mission to Mars with no return to Earth, both the < 30 and 30+ age groups responded that their decisions are affected due to delay in communication, effect of extreme temperature, and receiving information solely from automation. Results from cognitive tests illustrate that participants took more time to solve the simple math problems with audio in the background as compared to the math problems with no audio in the background. Even though they took more time to solve the math problems, their recall answers were still wrong 40% in total.

▼ The automotive industry is seen to be making a monumental paradigm shift from manual to semi-autonomous to fully Autonomous Vehicles. An Advanced Driver Assistance System (ADAS) forms a major building block for realizing these next generation of highly Autonomous-capable Vehicles. Although the general ADAS architecture is widely discussed, limited details are available about the functionality of the modules and their interactions, backed up by scientific justification. This limits the utilization of such an architecture for pragmatic implementation. A Cognitive ADAS Architecture for level 4 Autonomous-capable Electrified Vehicles (EV) is proposed in this thesis. Variations for levels 3 and 3.5 (combination of levels 3 and 4, with the primary fallback through a human driver and the secondary through an Automated Driving System) are also presented.
A validated simulation framework is built for highway driving based on the proposed level 4 architecture for an enhanced Tesla Model S. It was concluded that the autonomous control provided a 28% energy economy increase, on average, compared to human driver control. Through a quantitative sensitivity analysis, the optimal Mission/Motion Planning and energy management are seen in addition to a positive impact on the EV battery, motor, and dynamics, realized from the minimized instantaneous fluctuations. These factors are considered to contribute to this significant increase in the energy economy of an autonomous-controlled EV. Furthermore, this impact was seen to be relatively higher for autonomous longitudinal vehicle control compared to lateral. This difference in the improved operation of the Autonomous-capable EV components between the Automated Driving System and the human driver control was seen to be the highest for the battery current.
In overall, an increase in vehicle autonomy, resulted in an improvement in the EV performance, dynamics and operation of the battery and motor, compared to a human driver control.

▼ D.Ing. (Electrical & Electronic Engineering Science)
In the light of a history of more than a century, and reviving interest over the last three decades, battery powered electric vehicles are seen as one of the contributing technologies to alleviate transport problems in the future. This thesis is concerned with the use of energy in road transport. In particular, some selected aspects of the application of battery powered road vehicles are addressed. The thesis gives a brief background history and reviews the forces and factors which presently play a role in the developments and future application of battery electric vehicles. The main contribution, however, lies in the field of technical clarification of some aspects of electric vehicle theoretical analysis, which have not been addressed before. The first of these technical subjects is the analysis of energy consumption of vehicles when operating under non-steady driving conditions. The analysis results in simple but relevant expressions for the energy consumption of any moving vehicle during start-stop driving, as well as driving over a hilly route. The potential benefit of kinetic energy recovery can be quantitatively determined. The theory is then applied to battery electric vehicles and the results are compared to actual recorded energy consumption figures. The second technical investigation concerns the optimisation of electric vehicle drive systems with respect to mass. It is shown that optimized drive systems should be designed to suit both the energy density characteristics of the batteries used, as well as the particular characteristics of the drive cycle to which the vehicles will be applied.

▼ M.Sc. (Electrical & Electronic Engineering)
The behaviour of alternating current machines being fed from an electronic commutator is investigated. The performance of compound power switches for use in electric vehicle drives are examined. A detailed study on switching losses and base current characteristics based upon experimental measurements was carried out. With further reference to power switches the merit, development and functioning of an electronic commutator is discussed. Because of the close association between this study and electric vehicle drives, a comparative study of the performance of different rotor types within the same machine was executed. Attention is paid to torque and efficiency characteristics in particular. The influence of voltage and current harmonics was established by comparative testing of the machine with sinusoidal and electronic commutator excitation. The study shows that the highest specific power was attained with the alternating current machine with a wound rotor (synchronous machine) while there seems to be merit in the use of permanent magnet rotors for electric drives as well. On the average the use of electronic commutator excitation resulted in an efficiency decrease of approximately 15% for the a.c. machine with different rotor types. Efficiency and torque for an induction machine with solid rotor were disappointing so that there seems to be little application for solid steel rotors. A simple model for the synchronous machine with wound rotor was developed to explain the dependence of torque and efficiency upon speed of rotation and commutation angle. To conclude, guidelines are given for future studies on electric vehicle drives and machine types as primary drive.

▼ This thesis presents the system identification of the longitudinal motion of a small unmanned aerial vehicle with flexible characteristics. The unmanned aerial vehicle of study is an off-the-shelf aircraft with limited knowledge about the dynamic model. The first task in obtaining a model for flutter testing is determining the rigid body model. Specifically, this thesis will focus in the development of the aircraft and obtaining the longitudinal rigid body model. This involves the assembly and configuration of the avionics and sensors, performing experiments to determine mass and inertia properties and using software tools for aerodynamic analysis to get preliminary values for the static and dynamic stability derivatives. The next step was to design flight experiments for the purpose of system identification. The system identification focused on obtaining the longitudinal model and available software tools were used to get comparative results. The best model was identified using the parameter identification library which gave a 65% match in the pitch rate and 70% match in the vertical acceleration flight data from a doublet response. The short period mode was identified to have a frequency of 6.01 rad/s and a damping ratio of 0.977.

▼ Limit cycle oscillations (LCO), also known as utter, cause significant challenges in flight control of small unmanned aerial vehicles (SUAVs), and could potentially lead to structural damage and catastrophic failures. LCO can be described as vibrational motions in the rocking, pitching and plunging displacements of an aircraft wing. To address this, the use of synthetic jet actuators (SJAs) in UAV flight control systems is becoming popular as a practical alternative and to mechanical deflection surfaces.
Synthetic jet actuators are promising tools for LCO suppression systems in small UAVs due to their small size, ease of operation, and low cost. Uncertainties inherent in the dynamics of the synthetic jet actuators present significant challenges in the synthetic jet actuator-based control design. Specifically, the input-output characteristic (voltage-virtual deflection angle relationship) of the synthetic jet actuators is nonlinear and contains parametric uncertainty. Further control design challenges exist in situations where multiple actuators lose effectiveness.
This dissertation focuses on the suppression of limit cycle oscillations on small unmanned air vehicles using synthetic jet actuators. A brief description on how wind gust affects aircraft tracking control is presented. It shows an extension to a paper by adding the wind gust model to the system while also varying the uncertain synthetic jet actuator parameters using a Monte Carlo method. Next, a robust nonlinear control method is presented, which achieves simultaneous aircraft tracking control and limit cycle oscillation suppression using these synthetic jet actuators and a robust controller. Following that, a nonlinear LCO regulation method is presented, which uses a bank of dynamic filters to eliminate the need for pitching and plunging LCO rate measurements. Finally, an alternative method of LCO regulation control is presented, which utilizes a sliding mode observer in lieu of a bank of filters to estimate the pitching and plunging LCO rates.

▼ The use of Coulomb force has been analyzed in recent years to provide propulsion in space for various applications. Coulomb formation can also be utilized to make close formation spacecraft missions fuel efficient. In this study, the Coulomb formation of two craft is studied in elliptic chief orbits for two formation geometries. The first formation requires both spacecraft to be aligned along the nadir (radial) direction and the second formation requires both spacecraft to maintain a constant separation distance relative to each other while each spacecraft rotates freely on the surface of a sphere with the ratio of the radii being inversely proportional to the ratio of the masses. Two nonlinear optimal feedback control techniques are implemented to stabilize the dynamics of the Coulomb formation and maintain the desired formation while minimizing the energy costs. The control accelerations are compared to the analytical constraint accelerations obtained using the Udwadia-Kalaba equations for constrained motion. Due to the effects of plasma shielding, a Debye length model is incorporated in the nonlinear dynamics as a linear function of altitude of the formation's center of mass. The integrated thruster efforts are calculated for both optimal and analytical techniques and the fuel costs are determined and compared for both formations. The results demonstrated that the use of Coulomb force increases fuel efficiency for formation achievement and maintenance. The numerical analysis is performed on a) the highly eccentric Molniya orbit and b) the near-circular near-GEO orbit of the ERS-21.

▼ The aim of this thesis is to create a decision making algorithm. The goal would be to check the feasibility of the current maneuver by nding the probability of collision between the
subject and target
vehicles. These outputs can be used by other Advanced Driver Assistance System (ADAS) features including path planner, lateral control, longitudinal control, etc. We make use of some sensors like camera/radar (simulated data) and fuse these together for better estimation of measurements. With earlier experience with cameras, they are really poor at giving longitudinal distances whereas radars give more accurate measurements longitudinally. Using these measurements about targets ahead in the environment, we predict the trajectories of the obstacles/targets as well as the
subject vehicle (autonomous vehicle). The algorithm predicts if it is safe to continue with the current maneuver in the near future for several seconds ahead of time, and makes the decision if the maneuver is possible. The results are obtained using probabilistic approach whether the future trajectories are going to collide. The thesis primarily focuses on target tracking, e cient sensor data fusion and future collision estimation. With the lessons learnt using existing literature an e cient approach is employed. The simulation is performed in PreScan simulator and MATLAB. Enhancements in the sensor data fusion using standby measurements and quasi-decentralized approach to combine measurements to yield improved results and achieve better scalability are proposed and implemented.

▼ The Longbow Crew Trainer (LCT) is a cost effective, safe alternative to live training in the AH-64D/E Apache helicopter. Current Army doctrine and regulations have provisions for the limited use of simulator in lieu of aircraft hours toward semiannual minimum flight hour requirements. With the defense budget in decline, the Army must find innovative, cost effective methods to conduct realistic, relevant training to sustain proficiency in their warfighting capabilities. The LCT fully replicates the cockpit environment through training scenarios for requisite crew tasks and missions in a realistic, modular, and transportable solution. An attack helicopter crew can safely train in customizable scenarios ranging from basic aviation tasks to crew-level missions and gunneries. The Army is currently aligning one LCT per attack battalion under the Aviation Restructure Initiative. There are 20 Armed Reconnaissance Battalions/Squadrons in the active component with approximately 35 aircrews per battalion. The premise of this study was to review cost benefits of training in a virtual environment over a live environment while exploring the effects on proficiency. The difference in cost per hour between an AH-64D and the LCT is approximately 3,998. Using this figure and the semiannual flight hour requirements from the current Aircrew Training Manual in a weighted average between Flight Activity Category (FAC) 1 and FAC 2 pilot's flight minimum requirements formed the basis for four models: Low, Status Quo (baseline), Moderate, and High Virtual Simulation Models. This study found that while the High Virtual Simulation Model resulted in the greatest cost savings, the current budget and previous literature does not require such drastic measures. The Low Virtual Simulation Model resulted in higher costs. Therefore, the Moderate Virtual Simulation Model, proved most relevant to budget analysts, aviation unit commanders, and pilots by decreasing annual costs by an estimated 76.2 million without degrading proficiency.

▼ In 2010, NASA announced that its new vision is to support private space launch operations. It is anticipated that this new direction will create the need for new and innovative ideas that push the current boundaries of space exploration and contain the promise of substantial gain, both in research and capital.
The purpose of the study is to plan and estimate the feasibility of a mission to visit a number of near Earth asteroids (NEAs). The mission would take place before the end of the 21st century, and would only use commercially available technology. Throughout the mission design process, while holding astronaut safety paramount, it was the goal to maximize the return while keeping the cost to a minimum. A mission of the nature would appeal to the private space industry because it could be easily adapted and set into motion.
The mission design was divided into three main parts; mission timeline, vehicle design and power sources, with emphasis on nuclear and solar electric power, were investigated. The timeline and associated trajectories were initially selected using a numerical estimation and then optimized using Satellite Tool Kit (STK) 9.s's Design Explorer Optimizer [1]. Next, the spacecraft was design using commercially available parts that would support the mission requirements. The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) was and instrumental piece in maximizing the number of NEAs visited. Once the spacecraft was designed, acceptable power supply options were investigated. The VASIMR VX-200 requires 200 kilowatts of power to maintain thrust. This creates the need for a substantial power supply that consists of either a nuclear reactor of massive solar arrays.
STK 9.1's Design Explorer Optimizer was able to create a mission time line that allowed for the exploration of seven NEAs in under two years, while keeping the total mission ΔV under 71 kilometers per second. Based on these initial findings, it is determined that a mission of this nature is feasible and would could greatly benefit the private space industry.

▼ The introduction of connected automated
vehicles (CAV) offers significant societal benefits and economic opportunities while similarly posing major challenges to society, businesses, research, and regulatory bodies. In addition to directly affected markets, such as the automobile manufacturing and transportation sectors, insurance is one of the core downstream sectors acutely sensitive to the adoption of this emerging technology. In fact, the adoption of CAV technology has the potential to profoundly affect existing business models of insurers with key triggers arising from changes to liability frameworks, a changing risk landscape and changes of customer interfaces and market structure induced by a shift of societal mobility approaches.
Due to the facilitating role of insurers for the introduction of new technology, the strategic implications for this stakeholder have to be understood holistically and proactively to ensure a seamless introduction. Given that insurance as a
subject of academic research is interdisciplinary by character and since the strategic implications emerging with CAV technology originate from both legal and risk factors, this thesis provides a multidimensional research approach linking different research disciplines and research methods.
Using the current German liability and insurance framework as a case study, this thesis confirms that the methodology to allocate liability based on the strict liability of the vehicle owner is generally compatible with peculiarities of automated driving. However, adjustments to the existing framework are necessary to maintain an adequate level of claimant protection for accidents caused by automated
vehicles. In addition, this thesis highlights that an adequate ultimate allocation of liability costs is potentially inhibited because of several barriers that hinder the shift of liability costs to the manufacturer side. This is particularly because the ability and motivation of motor insurers to conduct subrogation claims is negatively affected by a lack of required technical and engineering know-how and because market-wide conduction of subrogation claims would erode the business volume of motor insurance.
In addition to legal challenges arising from existing liability and insurance frameworks, this thesis analyses data-driven use cases to present the access to in-vehicle data as another core CAV-related legal question from an insurance-perspective. Finding a status quo where OEMs begin to leverage their superior access to in-vehicle data for the expansion of their own business models, the analysis underlines that the increasing interconnection of modern automobile
vehicles will have a significant strategic impact on insurance-related service offerings. However, by analysing this status quo from a business ecosystem perspective, it becomes apparent that taking the role of a physical dominator to extract maximum short-term value might be an obvious but not necessarily successful approach for OEMs on long-term. This is because the shift from a goods-dominant…

▼ The objective of this project is to determine the advantages of the modern alternative fueled
vehicles over traditional
vehicles on a well to wheel basis. Alternative fueled
vehicles are often lauded for their advantages during vehicle operation. This project evaluates
vehicles according to their relative values on a broader scale.
This project compares traditional, alternative fuel, and hybrid
vehicles for use in the U.S. from the complete fuel cycle standpoint using points of comparison that include energy consumption, greenhouse gas emissions, and the emission of five principal pollutants. GREET software used in this study was developed at Argonne National Laboratory specifically for modeling these types of points. Financial considerations and social benefits outside the purview of GREET are also incorporated. The comparisons account for the attributes of each vehicle-fuel combination considering the feedstock, fuel production, and vehicle operation stages in order to provide a complete view of the fuel cycle. By comparing
vehicles in this way, this project highlights the advantages of each combination and provides insight into the overall effect of operating these vehicle technologies.

▼ Cognitive biases influence decisions and the analyses of risk. They are often derived from two separate processes: bias based on familiarity (familiarity bias) and bias as the result of influences from outside sources (persuasion bias). Research suggests that familiarity-based bias may lead to acceptance of an activity's drawbacks and a leniency of its risks.
In addition, research has tried to measure and analyze different types of biases individually, but few have compared the interactions of more than one bias at once. Because different biases may derive from different mental phenomena it is important to tease out the distinctions, and observe how they interact with each other. This study conducted an empirical test that attempted to answer the following questions: Does familiarity and affiliation of the topics of radiation, low-earth orbit, and space travel result in a lesser concern, and therefore leniency, of the risks involved? How effective is on-the-spot persuasion when discussing risk assessment? How well does increased familiarity of a high-risk activity protect against on-the-spot persuasion?
Surveys were distributed to 409 students from Embry-Riddle Aeronautical University. The surveys were meant to collect the familiarity and preference levels of the participants regarding commercial space travel; they were also meant to expose the participants to persuasion conditions in order to influence their perceptions of risk. Non-parametric tests were performed in order to test the interactions. Data show that no significant bias occurred as the result of persuasion; however significance was detected between participants with high familiarity and low familiarity when they were not intentionally persuaded. Implications of these results are included.

▼ This dissertation analyses the determinants of demand for new passenger vehicles in South Africa over a ten-year period, between 1995 and 2005. The following investigation into the determinants of demand for new passenger cars, is based both on a statistical and empirical analysis of the performance of the South African new passenger car market. Firstly, in Chapter 2 a brief history of the South African motor in industry provides a background for the analysis which follows in this dissertation and gives some insight into the historical developments that created the structure of the industry during the period analysed by the study. The theoretical components of the thesis focus on the macro-economic theory of demand, which seeks to explain the influences which determine consumer demand when purchasing durable goods and more specifically new passenger cars. Chapter 3 explains how consumers trade off preferences and substitutes in their efforts to maximise their utility. When comparing the general theory of
demand to the theory of demand for durable goods and more specifically the theory of demand for new passenger cars, it is demonstrated that the theory of demand for new passenger cars is inherently different to that of non-durable goods. New passenger cars and other durable goods require a relatively higher investment, last longer than non-durable goods and literally retain some of their value, as they get older. Chapter 3 creates a theoretical foundation upon which the determinants of demand for passenger cars will be analysed in Chapter 4. Chapter 4 forms the base upon which the South African New Passenger Car Market will to be analysed. In Chapter 4 the study statistically and graphically analyses the primary economic determinants of demand for new passenger cars. The analyses first present the relationship between price and new passenger car demand. It was found that demand for new passenger cars was price elastic. It was also identified that price elasticity of demand changed over the ten-year period analysed. Next, the impact of population growth and personal disposable income on new passenger car demand was analysed. It was discovered that should the population grow faster than the economy; relative prices unchanged, personal disposable income will decline and thereby affect desired stocks of new passenger cars negatively. The effect of disposable income on the sale of new passenger cars was found to be income inelastic. Income elasticity also, however displayed signs of change over the analysed period. The effect of the rate of interest on the demand for the new passenger cars was also analysed. The analysis indicated that changes in interest rates resulted in changes of various proportions in all rates of interest in the economy; such an effect filtered through to the new passenger car market. After this, the effect of GDP on the demand for new passenger cars was examined. The examination found that changes in the new passenger car market correlated very closely with GDP growth changes, hence GDP changes…

▼ This thesis is divided into three parts. The first part surveys 1,426 Americans to gauge how technology availability and costs influence public opinion, vehicle ownership decisions, travel, and location choices, and then adjusted all results for population weights, to offset any sample biases in U.S. demographics. Example results include average willing to pay (WTP) for full automation (on a newly acquired vehicle) of 3,252 with a very high standard deviation of +/- 3,861 with a human-driven-vehicle (HV) mode option and 2,783 (standard deviation = 3,722) without that option (AV driving only). These averages rise to 3685 and 3112 for AV with and without an HV option, respectively, if responses of zero WTP are removed. Americans’ average WTP for use of shared autonomous
vehicles (SAVs) is 0.44 per mile (standard deviation = 0.43). If given the option, Americans expect to set their
vehicles in AV (self-driving) mode 36.4% of the time. Respondents believe about 20% of AV miles should be allowed to travel empty, for both privately-owned AVs and shared AV fleets, which would be quite congesting in urban regions at many times of day. Among those likely to move their home in the next few years, 15.5% indicate that availability of AVs and SAVs would shift their new home locations relatively closer to the city center, while 10% indicate further away; the other 74.5% do not expect such technologies to influence their home location choices.
The second part develops a simulation-based framework to predict fleet evolution and VMT through year 2050, based upon regression models calibrated with the results of the survey the previous part of this thesis. Multiple scenarios are tested to analyze the effect of the difference in willingness to for AVs when the option to retain human driving capabilities in AVs is available vs. when it is not, as well as the effect of different rates of decline in the AV technology price premium. Both are shown to have a substantial effect on AV adoption rates. Home location is also analyzed, and a slight migration away from city centers is observed.
The third part uses Capital Metro’s transit bus fleet in Austin, Texas to analyze the costs and effects of implementing electric and autonomous technologies in transit bus fleets. Qualitative effects are discussed, financial effects are analyzed, and potential adoption schedules are developed. It is found that electric buses will become competitive with diesel in a few years, or immediately with a modest rise in diesel fuel prices within the range of historical levels. Autonomous buses will offer significant costs savings upon availability, and their implementation could ease the near-term cost burden associated with electric bus adoption in the near term before a substantial drop in electric technology price or rise in diesel fuel prices.

▼ The design of supersonic and hypersonic aerospace
vehicles is by nature a multi-disciplinary problem requiring the close integration of compressible fluid dynamics, heat transfer, and structural dynamics. The transient flow around the body must be accurately characterized in order to assess its effect on the thermal and structural responses; conversely, the thermal and structural behavior may significantly alter the aerodynamic performance. The core of this dissertation effort is concerned with the development and demonstration of an analysis and design capability for the aerothermoelastic behavior of high-speed aerospace
vehicles. This nominally involves coupling of the compressible Navier-Stokes equations for the fluid dynamics, the transient heat equation for the thermal response, and the elastodynamic equations for the structural dynamics. The streamline upwind Petrov-Galerkin (SUPG) stabilized finite element method is used for solving the compressible flow problem. Both a standard Galerkin and stabilized Galerkin gradient least squares (GGLS) finite element method are utilized for solving the heat equation, and a standard Galerkin method is used for solving the elastodynamic equations. The transient and steady-state responses of a problem are determined via a single, simultaneously coupled nonlinear system, thus bypassing accuracy and stability issues of classical staggered multi-physics coupling strategies. A gradient-based optimization framework is developed for designing transient coupled aerothermoelastic systems via adjoint-based sensitivity analysis. This framework is used to optimize the design of a structure in regard to thermal and structural performance. The efforts of this thesis have yielded a state-of-the-art approach for coupled aerothermoelastic analysis and design optimization.

▼ The work presented here provides a comprehensive dynamic and aerodynamic helicopter model. The possible applications of this work are wide including, control systems applications, reference and trajectory tracking methods implementation amongst others. The model configuration corresponds to a Sikorsky helicopter; a main rotor in perpendicular combination with a tail rotor. Also, a particular model of unmanned aerial vehicle has been modelled as part of collaboration with the La Laguna University (Spain). The modelling tool is VehicleSim, a program that builds rigid body systems, solves the nonlinear equations of motion and generates the time histories of the corresponding state variables of the vehicle under study. VehicleSim is able to provide the linearised equations of motion in a Matlab file and the symbolic state-space model. This is useful when control systems are to be designed. The main rotor model accounts for flap, lag and feather motions for each blade as well as for their nonlinear dynamic coupling. The tail rotor is modelled including the flap-feather coupling via delta three angle. The main and tail rotors' angular velocities are implemented by PID controllers. Main rotor linear and nonlinear equations are derived and validated by comparison with the theory. Main rotor flap and lag degrees of freedom are validated using frequency domain approaches in the absence of external forces. Also, fuselage-main rotor interaction is studied and validated by using modal analysis and root locus methodology. Vibrations originated at the main rotor are simulated and their effects on the fuselage are examined by a Short Time Fourier transformation. The aerodynamic model uses blade element theory on the main-tail rotors. Hover, climb, descent and forward flight conditions are simulated and they allow the helicopter to follow certain trajectories. Finally, the ensuing vibrations when an external perturbation is applied to the main rotor are investigated.

▼ In this thesis, VehicleSim multi-body software is used to extend and modify an existing motorcycle model by including different non-conventional suspension systems. Girder and Hossack double wishbones front suspension systems are designed, implemented and tested. Using a synthesis of mechanism methodology, they are designed with different kinematic configurations that allow different behaviours of the motorcycle front end. By means of CAD tools and finite element analysis, realistic three dimensional models of the suspension systems designs are developed. The dynamical properties of the mechanical assemblies are obtained from the CAD models and used to build a realistic mathematical model of a sport motorcycle fitted with theses alternative suspension systems. Dynamical and stability analyses of the alternative front suspension systems are performed. For the different kinematic configurations, anti-dive properties and variation of the motorcycle's handling geometric parameters are studied by non-linear dynamical simulations. Stability analyses are performed by means of the motorcycle linear models eigenvalues. Passive interconnection of front and rear suspension systems of a sport motorcycle is also investigated. The effects of an interconnected suspensions system on the motorcycle in-plane motions are studied by means of reduced order linear models. The baseline model is modified to include passive interconnection forces between the front and rear suspension systems. The possible improvement introduced by an interconnected suspensions system in terms of suspension accuracy is investigated through non-linear simulations with delayed step tyres inputs. Appropriate values of the interconnection passive components for different possible mechanical implementation are found by means of optimization processes. Linear stability analyses are performed for each of the different optimal interconnected configurations. Nonlinear frequency analyses of the motorcycle wheels and chassis responses are also performed considering the delay between the front and rear tyre inputs. Non-linear simulations with variable frequency sinusoidal road inputs are run for this purpose. Finally, modal analyses of the motorcycle model are carried out for variable interconnection parameters in order to understand the effect of the interconnected suspensions system on the motorcycle's motion.

▼ Silicon carbide (SiC), due to its low areal density and ability to stop tungsten carbide-cored bullets, is the ceramic armor of choice against heavy threats. Prochazka showed that SiC could be densified without using a liquid phase at about 2100°C using boron and carbon as additives, resulting in clean grain boundaries which give the material high hardness and excellent corrosion resistance. Well known liquid phase additives, such as yttrium aluminum garnet (YAG), Al, and Al-B-C, while lacking corrosion resistance, are all candidates for SiC-based armor and are known to increase fracture toughness. There is a hardness-toughness trade-off in silicon carbide that is related to fracture mode. The hardness of solid state SiC is essentially independent of grain size since it fractures transgranularly. While microcrack toughening can increase the toughness of SiC without decreasing hardness, additives can be used to engineer the amount of intergranular fracture and thereby increase the long-crack fracture toughness. Materials with single-edge precracked beam (SEPB) fracture toughness ranging between 2.5 and 8.5 MPam1 / 2 were prepared. To achieve high toughness it was necessary to have both intergranular fracture and elongated grains. Hardness decreased with increasing fracture toughness, independent of grain size for all but the finest grain sizes. Vickers hardness values generally decreased from 24 to 18 GPa as the toughness increased. Ballistic performance was independent of quasi-static fracture toughness and this parameter should not be pursued in making improved ceramic armor, at least at threat levels comparable to those tested. It was also shown that depth of penetration (DOP) was not a meaningful parameter for predicting the V 5 0 performance of advanced armor. DOP tests correlated with hardness measurements, which are not predictive of ballistic performance. Al was a better additive than Al-B-C or YAG for making advanced armor due to the low hot pressing temperature, better control of the microstructure and excellent ballistic performance. It can be made with a high Weibull modulus and appears to be an excellent choice when densifying SiC with applied pressure. A rich interplay in mechanical properties is available by understanding the roles of different additives in the densification process.

▼ Driving cycles is a series of data points representing the speed of vehicle verses time sequenced profile developed for certain road, route, specific area or city. It is widely used of application for vehicle manufacturers, environmentalists and traffic engineers. The purposes of this study are; to analyse the real world driving pattern and to develop a driving cycle for small and medium duty engines in Ipoh, Malaysia. This study carried out a survey to describe the motorcycle and car driving cycle on the selected three routes in the peak hour periods of the traffic condition, which are morning, afternoon and evening peak periods. The study used a GPS equipment to record vehicle travel speeds (second by second). The driving characteristics were analysed from speed time data and its target statistic parameters were defined. The method for generating the driving cycle has been described. The analysis results show that there are significant difference of driving characteristic and driving cycle between motorcycle and car for Ipoh city. The characteristic of the developed driving cycle for car was compared with three well established worldwide driving cycles. This information gives a clear message that those driving cycle such as ECE driving cycle (for instance) is not suitable to predict the emission standard in Ipoh. The driving cycle for motorcycle also had been compared with existing motorcycles driving cycles for Malaysia. It shows that the average speed of the developed Ipoh motorcycles driving cycle is higher than motorcycles driving cycle for Malaysia. The result clearly shows the driving cycle is dependent on specific area or city due to the different of traffic flow.

▼ This research studied on characteristics of the conventional paint spray compared to the High Volume Low Pressure (HVLP) type of paint spray used in the automotive painting industries in terms of cost and air quality in the spray booths. Characterization of conventional and HVLP of paint spray gathered through experimental methods. Results recorded from the experiments are air pressure, air volume, paint viscosity, transfer efficiency, and overspray. The analysed results are used as parameters in the Computer Fluid Dynamics (CFD) software ANSYS CFX V.15. The simulated paint spray patterns of the conventional paint spray compared to the High Volume Low Pressure (HVLP), concurred with the findings from the experiments. At the end of this research, it concluded that HVLP has a more stable flow rate compared to the conventional spray gun. HVLP produces smaller droplet size of paint thus reducing overspray impact on hygiene and surrounding environment. HVLP recorded 77.39% transfer efficiency which was 20% more than the conventional spray gun. The spray patternation of HVLP nozzle using ANSYS CFX Version 15 simulated a full cone and symmetry spray right after the paint discharge from the nozzle. In terms of practicality, the HVLP spray gun is more suitable for coating of a car’s part in the SME compared to the conventional spray paint.

▼ Malaysia is a tropical country with very high temperature during the day. Car users in Malaysia need in car air-conditioning system because the weather is hot and humid all year. Passenger adjusts the thermostat level (temperature knob setting) position to regulate the cold air temperature supplied to the cabin. By adjusting the thermostat, it affects the vehicle fuel consumption. When thermostat level is set to the lowest setting, compressor need to be driven on a regular basis and this require power from the engine. With the use of engine power, fuel consumption will increase. Fuel prices are very unstable and can get very high thus the need to lower its consumption. The objective of this study is to measure fuel consumption of different thermostat level setting of the air conditioning system, in the case of stationary cars and without passengers and driver in it. The data in this study were taken in four different modes and the two levels of the selected fan speed. At the same time the cabin temperature is monitored by specific device, to record the temperature, relative humidity and CO2. Fuel consumption was tested by filling 5 liters of petrol into the external tank. After one hour of testing, the total of fuel consumption can be calculated by measuring the amount of fuel remaining. At the end of the experiment, the most practical and suitable thermostat level setting will be propose based on the fuel consumption usage and according to the specifications of the appropriate level of comfort based on parameters such as temperature, relative humidity and CO2. Besides saving on fuel, it is also in this mode that the condition of temperature and humidity in the car’s cabin were found to be most comfortable. Recorded temperature is 25.83ºC, relative humidity 51.72% and CO2 is 553 ppm. The selected mode is at mode 4 low blower fan speed. The fuel consumption in this mode is amounted 1220 litres.

▼ Brake friction material is very important in braking system where they convert kinetic
energy of moving vehicles to thermal energy by friction during braking process. The
purpose of this research is to determine the optimal friction materials composition of
brake pad for light rail train system. Currently all the component of the train system
including brake pad is imported from overseas such as Germany. Hence, this research is
use to find the new formulation of the mixture ratio that may replace or compete with
the commercial available brake pad. Three different testing which are density and
porosity test, shore hardness test and wear test were done in order to select which metal
is the most suitable for railway application. Different composition were used,
(Cu30%BaSO430%), (Cu25%BaSO435%), (Cu20%BaSO440%), (Steel30%
BaSO430%), (Steel25% BaSO435%), (Steel20% BaSO440%), (Al30% BaSO430%),
(Al25% BaSO435%), and (Al20% BaSO440%) this study to determine the optimal
properties with lower wear rate. The selected material were mixed and compacted into
desired mould with 5 tons of pressure. The compacted samples were sintered using two
different temperatures which is 600 °C and 800 °C. Steel30% BaSO430% results in the
optimal composition since the result shows the lowest porosity, highest SD reading of
shore hardness and the lowest wear rate. The samples were analysed by using Scanning
Electron Microscopy (SEM) with an Energy Dispersive Spectrometry (EDS) system to
determine the morphology surface and overall composition of the samples. Comparing
different sintering temperature, the sintered sample of 800°C shows lower wear rate than
the sample sintered at 600°C. This is due to dense sample without crack showing by the
samples sintered at 800°C than at 600°C.

▼ Bilangan kenderaan di atas jalan raya mengalami peningkatan pada setiap tahun. Ianya
membawa kepada kesesakan jalan raya terutama di dalam kawasan bandar.
Pengangkutan bas awam merupakan pilihan terbaik sebagai alternatif bagi
mengurangkan kesesakan. Namun begitu, terdapat beberapa halangan daripada
pengusaha syarikat bas itu sendiri untuk memberi dan mengekalkan kualiti
perkhidmatan kepada penumpang pada tahap yang memuaskan. Kos operasi bas
merupakan salah satu faktor yang memberi kesan terhadap kualiti perkhidmatan bas.
Sebanyak 50% kos operasi bas yang perlu ditanggung oleh pengusaha bas terdiri
daripada bahan bakar. Oleh itu, kajian ini diperlukan untuk mengkaji pemanduan bas
dalam kawasan bandar dan kesannya terhadap penggunaan bahan bakar. Objektif utama
kajian ini adalah mentafsirkan jumlah penggunaan bahan bakar bagi pemanduan bas
dalam kawasan bandar dan seterusnya menentukan pemanduan bas yang menggunakan
jumlah bahan bakar tinggi. Data yang dikumpul adalah pada keadaan sebenar
melibatkan dua laluan di sekitar Lembah Klang dengan menggunakan alat Sistem
Kedudukan Global (GPS). Data yang diperolehi kemudian dimodelkan dengan
menggunakan perisian SIDRATRIP. Analisis menunjukkan bahawa pecutan merupakan
faktor utama yang mempengaruhi penggunaan bahan bakar. Penggunaan bahan bakar
paling tinggi adalah pada julat pecutan 2.01 m/s2 hingga 2.50 m/s2. Pemanduan dari
keadaan pegun untuk 30km/j pertama memberi kesan penggunaan bahan bakar tinggi
sebanyak 67% kadar kenaikan kerana pemandu menggunakan kadar pecutan yang
tinggi. Seterusnya, kelajuan 30km/j – 70km/j hanya memberi kesan sebanyak 10% kadar
kenaikan penggunaan bahan bakar. Manakala, kelajuan yang melebihi 70km/j memberi
impak yang besar terhadap penggunaan bahan bakar tinggi sebanyak 19% kadar
kenaikan. Hasil kajian membuktikan bahawa penggunaan pecutan yang tinggi akan
memberi impak yang besar terhadap penggunaan bahan bakar.

▼ Automobile exhaust emission control is one of trending issues in automotive research
field. Ceramic and metallic catalytic converters are the most common types of catalytic
converters. Most current researches focus on the modeling and characterization of
catalytic converter and there is a lack of exhaust gas conversion data of different catalyst
types that correspond to real engine operating condition. This project focuses on
comparing and analyzing the performance of ceramic and metallic catalytic converter on
its conversion efficiency. Mitsubishi 4G93 1800cc gasoline engine was attached with a
dynamometer and Kane Auto 5-1 series exhaust gas analyzer were used for emission
measurements of carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NOx) in
different speed and constant load. The experimental results of the engine performance
and exhaust emission were used to compare the performance of ceramic and metallic
catalytic converters in reducing the concentration of the exhaust emission without
affecting the engine performance. Based on the result, metallic catalytic converter
showed a higher 97.9% reduction of CO concentration reduction emission as compared
to the ceramic catalytic converter. The ceramic catalytic converters on the other hands
showed better reduction of NOx and HC concentration of 87.2% and 85.4% percentage
of reduction. It can be concluded that metallic catalytic converters performs a better
exhaust gas conversion on high temperature condition at reducing CO emission while
ceramic catalytic converters reduced HC and NOx emission more effectively due to its
lower thermal conductivity.

▼ Motorcycle is a major personal transport mode in Malaysia. However, majority of road
accidents fatalities involve motorcyclist. Royal Malaysian Police reported that head is the
most part of body casualties and fatalities in year 2014. One of the strategies to mitigate
this problem is through proper usage of safety helmet. Thus, this study was introduce a
new approach on motorcyclist safety using Technology Acceptance Model (TAM) with
additional variables. TAM is a theory model used by researcher to examine the factor of
acceptance of new technologies among users. To test the hypothesized model, 319 of
respondents among motorcyclist was chosen as a sample size. The Structural Equation
Modelling (SEM) approach was performed to test full structural model. The result shows
that the goodness of fit indices are excellent fit and all variables (perceived usefulness,
perceived ease of use, descriptive norm, subjective norm and perceived safety) were
statistically significant towards behavioral intention to use Safety Helmet Reminder
System (SHR). It demonstrates that SHR is significantly improve the helmet use among
motorcyclist. R2 value of .77 shows that 77% change in the criterion variables is caused
due to the change taking place by a combination five predictor variables. Perceived Safety
was found the most dominant variables towards behavioral intention to use Safety Helmet
Reminder system. Therefore, TAM model with extended variables are suitable to predict
the behavioral intention to use SHR system among motorcyclist. The conceptual of SHR
system is proposed to function effectively and directly will increase safety helmet usage.

▼ U-turning movements at roadway segments are channelized and aided with splitting
islands in the middle so that drivers can be on their desired trajectories and the road
segment are often accompanied with weaving, merging and diverging movement. The
objectives are to determine the speed differences (Vd), reaction time (RT) and safe
distance where from those parameters and their relationships, the statistical model was
developed and used in estimating the safe distances to execute the lane changing within
the U-turn facilities. The data were taken from the field which is video recording,
picture and geometric design and was used to simulate the driving simulator like an
actual environment while the driving simulator come out with the speed differences,
reaction time and distance as a raw data. Result show that the mean value of reaction
time (RT) of the driver in making the lane changing at the U-turn area is 2.5s where
the distance to execute the lane changing is 16.467m from the merging vehicle.
Through the relationship between the RT, Vd and distance of the subject vehicle within
U-turn facilities, the findings from the statistical model has been developed with the
equation [Safe distance = (13.448 + 1.410 RT – 0.075 Vd)]. The model was used to
estimate the safe distance which is 15.00m within U-turn facilities. The result shown
that the safe distance will increase when the driver slowing down their speed and
increasing the reaction time. The research concluded that the speed difference and
reaction time have a significant relationship in estimating the safe distance in executing
the lane changing within U-turn facilities.
