▼ The present research work has been carried out to develop a unified knowledge-based hybrid methodology combining regression-based, lumped parameter and finite element analyses that can be implemented in the initial phase of vehicle design resulting in a superior side crash performance. As a first step, a regression-based model (RBM) is developed between the injury parameter Thoracic Trauma Index (TTI) of the rear SID and characteristic side impact dynamic response variables such as rear door velocity (final) and intrusion supplementing an existing RBM for front TTI prediction. In order to derive the rear TTI RBM, existing public domain vehicle crash test data provided by NHTSA has been used. A computer-based tool with a Graphical User Interface (GUI) has been developed for obtaining possible solution sets of response variables satisfying the regression relations for both front and rear TTI. As a next step in the formulation of the present hybrid methodology for vehicle side impact safety design, a new Lumped Parameter Model (LPM) representing NHTSA side impact is developed. The LPM developed consists of body sub-systems like B-pillar, front door, rear door and rocker (i.e. sill) on the struck side of the vehicle, MDB, and “rest of the vehicle” as lumped masses along with representative nonlinear springs between them. It has been envisaged that for the initial conceptual design to progress, the targets of dynamic response variables obtained from RBM should yield a set of spring characteristics broadly defining the required vehicle side structure. However, this is an inverse problem of dynamics which would require an inordinate amount of time to be solved iteratively. Hence a knowledge-based approach is adopted here to link the two sets of variables i.e., the dynamic response parameters (such as average door and B-pillar velocities, door intrusion, etc.) and the stiffness and strength characteristics of the springs present in LPM. In effect, this mapping is accomplished with the help of an artificial neural network (ANN) algorithm (referred to as ANN_RBM_LPM in the current work). To generate the required knowledge database for ANN_RBM_LPM, one thousand cases of LPM chosen with the help of the Latin Hypercube technique are run with varying spring characteristics. The goal of finding the desired design solutions describing vehicle geometry in an efficient manner is accomplished with the help of a second ANN algorithm which links sets of dynamic spring characteristics with sets of sectional properties of doors, B-pillar and rocker (referred as ANN_LPM_FEM in the current work). The implementation of this approach requires creation of a knowledge database containing paired sets of spring characteristics and sectional details just mentioned. The effectiveness of the hybrid methodology comprising both ANN_RBM_LPM and ANN_LPM_FEM is finally illustrated by improving the side impact performance of a Honda Accord finite element model. Thus, the unique knowledge-based hybrid approach developed here can be deployed in real world… Advisors/Committee Members: Deb, Anindya (advisor).

▼ Luge is an Olympic sport in which athletes ride feet-first on sleds down an ice-covered track. Competitors spring from the starting position and accelerate their sled by paddling with spiked gloves against the ice surface. Once the Luger leaves the starting section, their downhill motion is solely propelled by the effects of gravity. Athletes compete, one after the other, for the fastest time. Runs can differ by as little as a thousandth of a second, meaning that every minor sled adjustment, change of line choice, and shift of body position is critical. In the past, the sport of Luge has progressed through a series of steps involving trial and error, where changes to the sled and strategy rely more on intuition and race results, rather than in-depth, mathematical analysis. In an effort to try and improve track times for the US Olympic Luge team, a track and driver model is in development in order to simulate a sled going down the track. By doing this, the hope is to be able to pinpoint areas of possible improvement to the sled and see how adjustments can affect the optimum line down the track. A part of this model, which is the focus of the following paper, is the inclusion of an analysis to identify the frictional relationship between the ice surface and the steels of the sled. The model created of the ice-steel interaction was put in the form of a function file, which includes inputs of down force, ice temperature, sled velocity, and steel geometry. Creation of this model and completion of a set of parametric studies allowed for further understanding the interaction between the sled steels and ice surface, specifically applying to the sport of Luge. The model predicts for lower temperatures that at slower sled velocities the coefficient of friction is greater compared to faster sled velocities. This relationship inverts as the ice temperature moves closer to the melting temperature. A sharper steel edge radius was found to be beneficial in lowering the coefficient of friction at lower sled velocities. The sharp edge radius friction benefit decreases as the sled speed increases and is predicted to actually increase friction slightly compared to duller blades at greater velocities. A flat as possible rocker radius lowers friction at all sled velocities, as well as in banked turns where two contact patches are possible. On curves, the pressure on the steel is increased due to the effects of centripetal accelerations. A 1 g versus 5 g normal loading, experienced on the last turns of the track, increases the coefficient of friction on the blade, but also increases the allowable lateral force on the sled before side slip occurs. Understanding the relationships of these parameters, along with the information that may be gained from the driver model, may prove to be useful in choosing optimum sled characteristics and line choice.

▼ One of the most important data elements recorded in the National Automotive Sampling System / Crashworthiness Data System (NASS/CDS) is the vehicle change in velocity, or ?V. ?V is the vector change in velocity experienced by a vehicle during a collision, and is widely used as a measure of collision severity in crash safety research. The ?V information in NASS/CDS is used by the U.S. National Highway Traffic Safety Administration (NHTSA) to determine research needs, regulatory priorities, design crash test procedures (e.g., test speed), and to determine countermeasure effectiveness. The WinSMASH crash reconstruction code is used to compute the ?V estimates in the NASS/CDS. However, the reconstruction accuracy of the current WinSMASH version has not previously been examined for side impacts. Given the importance of side impact crash modes and the widespread use of NASS/CDS data, an assessment of the program's reconstruction accuracy is warranted. The goal of this thesis is to quantify the accuracy of WinSMASH ?V estimations for side impact crashes, and to suggest possible means of improving side impact reconstruction accuracy. Crash tests provide a wealth of controlled crash response data against which to evaluate WinSMASH. Knowing the accuracy of WinSMASH in reconstructing crash tests, we can infer WinSMASH accuracy in reconstructing real-world side crashes. In this study, WinSMASH was compared to 70 NHTSA Moving Deformable Barrier (MDB) - to - vehicle side crash tests. Tested vehicles were primarily cars (as opposed to Light Trucks and Vans, or LTVs) from model years 1997 - 2001. For each test, the actual ?V was determined from test instrumentation and this ?V was compared to the WinSMASH-reconstructed ?V of the same test. WinSMASH was found to systemically over-predict struck vehicle resultant ?V by 12% at time of vehicle separation, and by 22% at time of maximum crush. A similar pattern was observed for the MDB ?V; WinSMASH over-predicted resultant MDB ?V by 6.6% at separation, and by 23% at maximum crush. Error in user-estimated reconstruction parameters, namely Principal Direction Of Force (PDOF) error and damage offset, was controlled for in this analysis. Analysis of the results indicates that this over-prediction of ?V is caused by over-estimation of the energy absorbed by struck vehicle damage. In turn, this ultimately stems from the vehicle stiffness parameters used by WinSMASH for this purpose. When WinSMASH was forced to use the correct amount of absorbed energy to reconstruct the crash tests, systemic over-prediction of ?V disappeared. WinSMASH accuracy when reconstructing side crash tests may be improved in two ways. First, providing WinSMASH with side stiffness parameters that are correlated to the correct amount of absorbed energy will correct the systemic over-prediction of absorbed energy when reconstructing NHTSA side crash tests. Second, providing some treatment of restitution in the reconstruction process will correct the under-prediction of ?V due to WinSMASH's assumption of zero restitution.

▼ Thoracic injury is the most dominant segment of automotive side impact traumas. A numerical model that can predict such injuries in crash simulation is essential to the process of designing a safer motor vehicle. The focus of this study was to develop a numerical model to predict lung response and injury in side impact car crash scenarios. A biofidelic human body model was further developed. The geometry, material properties and boundary condition of the organs and soft tissues within the thorax were improved with the intent to ensure stress transmission continuity and model accuracy. The thoracic region of the human body model was revalidated against three pendulum and two sled impact scenarios at different velocities. Other body regions such as the shoulder, abdomen, and pelvis were revalidated. The latest model demonstrated improvements in every response category relative to the previous version of the human body model. The development of the lung model involved advancements in the material properties, and boundary conditions. An analytical approach was presented to correct the lung properties to the in-situ condition. Several injury metric predictor candidates of pulmonary contusion were investigated and compared based on the validated pendulum and sled impact scenarios. The results of this study confirmed the importance of stress wave focusing, reflection, and concentration within the lungs. The bulk modulus of the lung had considerable influence on injury metric outcomes. Despite the viscous criterion yielded similar response for different loading conditions, this study demonstrated that the level of contusion volume varied with the size of the impact surface area. In conclusion, the human body model could be used for the analysis of thoracic response in automotive impact scenarios. The overall model is capable of predicting thoracic response and lung contusion. Future development on the heart and aorta can expand the model capacity to investigate all vital organ injury mechanisms.

The purpose of this research project was to examine the performance of rear-facing child restraint devices (RFCRD) involved in side impact crashes. Side impact crashes are the second highest crash mode reported by the National Highway Traffic Safety Administration (NHTSA). Child restraint devices (CRDs) are being installed in the center seating position of vehicles because it is thought to be the safest position in the vehicle due to the distance from any intrusion. Children are still being injured in side impact crashes due to the child restraint device moving toward the direction of impact and colliding against the intruding sheetmetal and interior components of a vehicle hit in the side. Testing done by the NHTSA in the Side Impact New Car Assessment Program (SINCAP) in 2007 placed RFCRDs in test vehicles. Subjective analysis of the SINCAP high speed video raised the question examined in this research about the excursions and potential injury of the child occupants in side impacts. The first part of this study examined the maximum head excursion of a 12 month CRABI anthropomorphic test device (ATD) placed in RFCRDs at a change in velocity of 35 km/h (22mph). The change in velocity was determined by using the average of four popular selling small and mid-size vehicles' crash tested by the NHTSA SINCAP program. The purpose of the test series was to determine if a child occupant placed in a CRD in the center seating position would impact the door of a vehicle involved in a higher speed side impact event, such as the NHTSA SINCAP program where a moving deformable barrier traveling at 62 km/h (38.5 mph) impacts the side of a vehicle. After determining the excursion of the ATD head, and determining if the head would hit an intruding door during a side impact event, the ATD and CRD were impacted into a simulated door to determine injury potential at 35 km/h (22 mph) change in velocity. Tests impacting the simulated door were also conducted at 29 km/h (18 mph), and 24 km/h (15 mph) to determine injury potential. In all the sled tests done at 35 km/h (22 mph) the ATD head moved into the crush zone of a sample of smaller and mid-sized vehicles. The potential for severe head injury using all the tested RFCRDs at 35 km/h (22mph) was high when impacting a simulated door. The threshold for lower injury potential was at 24 km/h (15 mph). When the ATD did not impact anything at 35km/h (22 mph) the potential for severe head injury was also low. This study concludes that testing of CRDs needs to be done at higher speeds to better protect children involved in higher speed side impact crashes. Head injury values and excursions both need to be evaluated for reducing injury potential.

Children are still being injured in side impact crashes due to the child restraint device moving toward the direction of impact and colliding against the intruding sheetmetal and interior components of a vehicle hit in the side. Testing done by the NHTSA in the Side Impact New Car Assessment Program (SINCAP) in 2007 placed RFCRDs in test vehicles. Subjective analysis of the SINCAP high speed video raised the question examined in this research about the excursions and potential injury of the child occupants in side impacts. The first part of this study examined the maximum head excursion of a 12 month CRABI anthropomorphic test device (ATD) placed in RFCRDs at a change in velocity of 35 km/h (22mph). The change in velocity was determined by using the average of four popular selling small and mid-size vehicles' crash tested by the NHTSA SINCAP program. The purpose of the test series was to determine if a child occupant placed in aCRD in the center seating position would impact the door of a vehicle involved in a higher speed side impact event, such as the NHTSA SINCAP program where a moving deformable barrier traveling at 62 km/h (38.5 mph) impacts the side of a vehicle. After determining the excursion of the ATD head, and determining if the head would hit an intruding door during a side impact event, the ATD and CRD were impacted into a simulated door to determine injury potential at 35 km/h (22 mph) change in velocity. Tests impacting the simulated door were also conducted at 29 km/h (18 mph), and 24 km/h (15 mph) to determine injury potential. In all the sled tests done at 35 km/h (22 mph) the ATD head moved into the crush zone of a sample of smaller and mid-sized vehicles. The potential for severe head injury using all the tested RFCRDs at 35 km/h (22mph) was high when impacting a simulated door. The threshold for lower injury potential was at 24 km/h (15 mph). When the ATD did not impact anything at 35km/h (22 mph) the potential for severe head injury was also low. This study concludes that testing of CRDs needs to be done at higher speeds to better protect children involved in higher speed side impact crashes. Head injury values and excursions both need to be evaluated for reducing injury potential.

▼ Car accidents are amongst the most common causes of fatalities for a younger population in developed countries and world-wide. While research using Anthropometric Test Devices (ATDs) has led to improvements in frontal impact occupant protection, epidemiological data on the effectiveness of devices for side impact protection remains inconclusive. Current regulatory physical side impact tests are limited to standardized full-vehicle Moving Deformable Barrier and rigid pole impacts, only one seating position of the occupant, and a unidirectional occupant surrogate (side impact ATD). To address some limitations of the existing research methods, and expand the understanding of the occupant response and potential for injury, numerical Human Body Models (HBMs) have been developed as repeatable, biofidelic, omni-directional, and frangible occupant surrogates. The overall goal of this study was to improve the understanding of the underlying sources of conflicting epidemiological and physical test data on thoracic response in side impacts. This study applied two highly detailed HBMs in parametric investigations with simple to complex impact scenarios ranging from a pendulum, rigid-wall side sled, to a full-vehicle lateral impact and an accident reconstruction. Subsequently, a thoracic side airbag and three-point seatbelt models were developed and integrated with the vehicle model to study the effect of occupant pre-crash position on the potential for injury. Occupant response assessment included global criteria (chest deflection and viscous criterion), local measurements at different thorax levels, spine kinematics, and prediction of rib fracture locations and lung response. This research identified limitations in current analysis methods, demonstrating effects on occupant response of pre-crash arm position, which is known to vary widely among occupants. The magnitude of the arm effect was dependent on the lateral impact scenario, where the occupant response demonstrated the highest sensitivity to arm orientation in the full vehicle impact. The arm position effect was more significant than changes in response to four restraint combinations, where the assessment of the restraint performance was also dependent on the thoracic response measurement locations and method. A parametric study using detailed HBM, vehicle and restraint models provided new understanding of occupant response in side impact crash scenarios.

The domain of Sustainable Development innovation is facing a significant transformation. Several trends, social, political, economical forces and players are concurring in the rise the concept of impact on sustainable development challenges. That is being introduces in the strategies of big and small enterprises, at different degrees, varying from innovations along the value chain to small adaptive tactics keeping the pace with the latest governmental regulation in matters of emissions reductions, workforce welfare etc. Moreover, a growing number of emerging startups already include sustainable development challenges in their DNA as a main mission -often called Impact Startups. However, being hybrids with ambitious impact change goals and financial sustainability needs, they often struggle to survive and develop models of impact. In this context, BMI Lab is a consultancy supporting organisations with business model innovation. The current process does not account for ‘impact drivers’ in the equation for business model generation, therefore does not have the capabilities to support impact startups, and will need to evolve to do so. The project arouse from the knowledge gap of including Sustainable Development Impact as an additional driver in business model generation. The aim is to provide a strategic design angle to complement the Business Model Design Sprint, based on an explorative approach over the impact factors and challenges in achieving impact models. First, the concept of impact model is defined, then based on field immersion, impact entrepreneurs and experts stories and interviews, and academic sources, the research identifies a set of critical activities that could positively influence the development of impact models. Those have been embedded in a toolkit. The toolkit takes place in the first day of a BMI Lab BM generation Sprint and aims at guiding through the identification of new opportunities that align SD goals and viability. It consist of four main stages focusing on the value exchanged with the ecosystem of intervention.

▼ As the development of highways, it is quite normal for buses running in a speed around 100km/h. When buses are running in a high speed, they may suffer from the influence of side wind disturbances at anytime. Sometimes, it may result in traffic accidents. Therefore, the study of bus stability under side wind disturbances becomes more and more important. Due to restrictions of real tests, computer simulation can be used to study this subject. The bus side wind response character is reflected through the driver’s manoeuvre , so open-loop analysis is hard to give a comprehensive evaluation of the side wind stability of the bus. Therefore, closed-loop analysis is studied in this thesis. An ADAMS bus model and a side wind force model are developed in this thesis, along with two driver models, the PID control model and the preview curvature model. The driver models are built in Simulink and co-simulation between ADAMS/View and Simulink is conducted. The results of co-simulation show that the two driver models can both control the bus from deviating from the desired course under side wind disturbances. The PID control model is simple and shows a very good control effect. The maximum lateral displacement of the bus by PID control model is just 0.0205m under maximum side wind load 1000N and 2500Nm when preview time is 1.2s, while it is 0.0702m by preview curvature model, however, it is difficult to determine the coefficients Kd, Kp, and Ki in the PID controller. The preview curvature model also shows a good control effect in terms of the maximum lateral displacement and yaw angle of the bus. Comparing these two models, the PID control model is more sensitive to deviations, with quicker response and larger steering input. The bus model system is stable under side wind disturbances. Through driver ’s proper steering manoeuvre, the bus is well controlled. The closed-loop analysis is a good method to study the bus stability under side wind disturbances.

▼ This thesis discusses the breach initiation processes at the land-side slope of a dike, due to overflow and wave overtopping. To date still little is known about the actual failure process of land-side slope covers. Therefore, starting in 2007, numerous wave overtopping experiments have been executed in The Netherlands and Belgium using a wave overtopping simulator. This simulator simulates different kinds of storm events by releasing volumes of water over the land-side slope according to a predetermined schedule. Flanders Hydraulics Research and Delft University of Technology per- formed another wave overtopping experiment in November 2015. The wave overtopping simulator as well as a new designed overflow simulator were used to test the breach initiation processes of the land-side slope of a river-dike adjacent to the river Scheldt, near the Wijmeers-II polder in Belgium. The data obtained from this experiment is presented in this thesis, and was used to evaluate current damage initiation theories. Currently the most advanced approach for determining the amount of erosion, or ’damage’, to the land-side slope is the ’Excess volume approach’ by Hughes [17, 18] who based his model on earlier developed models by Van der Meer [36] and Dean et al. [10]. This approach determines damage on the land-side slope based on overflow theories and overflow experiments (CIRIA experiments [13]). An overtopping wave is thereby modelled as a very short overflow event in which damage is assumed to be bottom shear stress induced. The Excess volume approach has therefore been applied on the Wijmeers-II data in order to verify the predictive accuracy of this theory. Contrary to the experimental outcome, the Excess volume approach predicted a heavier damage on the overflow test sections than on the wave overtopping test section. Due to these test results the correct representation of reality of the Excess volume approach is questioned in this thesis. Extensive investigation of video material obtained during the experiments showed that overtopping waves separate from the slope before reattaching with the slope. This separation time leads to a jet flow impacting the slope under an angle. Due to a decrease in discharge during a wave overtopping, the impact location moves towards the crest within the overtopping time of a wave. This discovery led to the development of a new modelling approach in which this phenomenon is considered. In this new ’Wave impact approach’, damage on the grass cover is assumed to be caused by wave overtopping induced jet pressures in cracks in the grass cover. These cracks are present due to weather conditions and temperature influences in the supporting clay layer. Wave overtopping induced jet pressure in the crack pushes the walls further aside leading to growth of the crack. This crack growth continues until the pressure in the crack becomes too high and grass aggregates are lifted from the cover. This crack growth is assumed to only occur when the wave overtopping induced jet pressure in the crack exceeds a… Advisors/Committee Members: Van Rhee, C. (mentor), Van Damme, M.

▼ Motor vehicle crashes claim thousands of lives each year in the US, and injure millions more. The thorax is the region of the body at greatest risk for serious injury, and thus is of interest for increased protection. In order to improve systems providing occupant protection, a better understanding of the thorax is required, particularly for vulnerable occupants. The work of this dissertation is focused on increasing understanding of the thorax, and does so by examining instrumentation commonly used on the thorax, by introducing a novel analysis technique for understanding thoracic characteristics, and finally by presenting response and injury data for side impact loading.The first study presented here provides an answer to the question, “Do chestbands alter thoracic response to impact?” This was accomplished by conducting a series of repeated impacts on two post-mortem human surrogates (PMHS), at the same impact velocity with 0, 1, and 2 chestbands. This was done for various impact speeds for a total of 22 impacts on the two subjects. `Response’ was divided into global response, defined as chest deflection and thoracic stiffness, and local response, defined as the individual rib strain. Results showed no significant difference in global or local response, thus providing support for the commonly held assumption that chestbands do not alter thoracic response to impact.The second study introduces an analysis method, looking at rib strain as a function of chest deflection. An understanding of this relationship is intended to help bridge the gap between existing deflection-based injury criteria and strain-based injury prediction in finite element human body models. To this end, the strain-deflection (S-D) relationship was explored by rib level, fitting five different models to the data and constructing response corridors. It was additionally observed that the S-D relationship, or curve trajectory, tends to remain consistent across impacts on the same subject, even when those impacts are conducted at different velocities.The final study of this work begins an examination of thoracic response and injuries occurring in small, fragile, elderly females involved in side impact vehicle crashes. The testing methodology is described, which includes a door intrusion and lateral underbody motion applied to a subject who is placed on a mass-production driver seat equipped with a side airbag, belted (with pretensioner), and interacts with a mass-production door liner. Rib fractures were the most common injury observed, with the first fractures occurring anteriorly on the struck side, followed by fractures anteriorly on the non-struck side and fractures posteriorly on the struck side. Spinal acceleration values, chest deflections, airbag pressures, and seatbelt tensions are reported. While this study does provide a valuable understanding of the injuries in the employed impact mode, it is intended that future tests similar to these may be conducted and that the combined dataset may be used to produce response corridors and a thoracic… Advisors/Committee Members: Bolte, John H., IV (Advisor).

▼ The biofidelity of pediatric ATDs continues to be evaluated with scaled-down adult data, a methodology that makes inaccurate assumptions about the likeness of biomechanical properties of children and adults. Recently, evaluation of pediatric ATDs by comparison of pediatric volunteer (PV) data has been shown to be a valuable and practical alternative to the use of scaled adult data. This study utilized existing PV data to evaluate a 3 year-old side impact ATD, the Q3s. While ATDs have been compared to volunteer responses in frontal impacts, this study is the first to extend ATD-PV comparison methods to the Q3s ATD, and among the first to extend these methods to side impacts. Previously conducted experiments were replicated in order to make a direct comparison between the Q3s and PVs. PV data were used from 4-7 year-olds (shoulder tests, n=14) and 6-8 year-olds (sled tests, n=7). Force-deflection data were captured during quasi-static shoulder tests through manual displacement of the shoulder joint. Resulting shoulder stiffness was compared between the Q3s and PVs. Low-speed far-side sled tests were conducted with the Q3s at lateral (90 degrees) and oblique (60 degrees) impacts. Primary outcomes of interest included 1) lateral displacement of the torso, 2) torso rollout angle, and 3) kinematic trajectories of the head and neck. The Q3s exhibited shoulder stiffness values at least 32 N/mm greater than the PVs for all conditions (PV muscle tensed and relaxed, deflection calculated for full- and half-thoracic). In lateral sled tests, the Q3s demonstrated increased lateral torso displacement (Q3s: 194.6 mm; PVs: 164.3 mm ± 26.6), coronal torso rollout (Q3s: 49.2 degrees; PVs: 35.7 degrees ± 12.4), and maximum excursions in the Y and Z directions for trajectories of the top of the head, C4, and T1, compared to PVs. In oblique trials, the Q3s did not exhibit significantly different lateral torso displacement or rollout, but achieved less forward X motion (Q3s: 68 mm; PVs: 113 ± 17 mm) compared to PVs. Increased Q3s ATD shoulder stiffness suggests an effect on loads seen by the Q3s head, torso, and neck during side impact. Q3s and PV trajectories were of similar shape, although Q3s head kinematics displayed rigid body motion followed by independent lateral bending of the head, suggesting cervical and thoracic spine rigidity compared to PVs.

▼ Electric automobiles are becoming more common in today’s society. Since interior car noise can have negative mental health effects for the driver and passengers, it becomes relevant to find out how it is being generated. One important source of noise is the surface pressure fluctuations caused by shear layer impingement and turbulence from the flow around a side-view mirror. Even though many studies about the flow past a side-view mirror have been done, there is not sufficient research for lower speed cases at which electric cars drive at. The purpose of this project is therefore to study the flow around a generic side-view mirror and investigate how it generates noise for some of these cases. The computational fluid dynamics (CFD) software STAR-CCM+, running both steady and unsteady Reynolds-Averaged Navier Stokes (RANS) simulation models is used. Three cases at different freestream speeds of 20, 30 and 40 m/s are simulated. To ensure accurate results, a mesh independence study is carried out for the 40 m/s case with steady RANS simulation. The final mesh is then used to simulate the 20 and 30 m/s cases as well. The steady flow fields were obtained using the realizable k −" model and later used as initialization fields for the unsteady cases, were SST k − ! model is used. Pressure fluctuations data series of specific sensors placed on the surfaces of the mirror and window where analyzed for their power spectral density (PSD) in the frequency domain. For sensors placed in the back of the mirror and on the window inside the recirculation region, noticeable peaks at 500-1300 Hz in the signal’s power were observed. Comparison of the PSD’s against the Strouhal number revealed that the power peaks are due to coherent structures in the free shear layer developed from the mirror edges. Those PSD peaks will generate tonal noise which is of 500-1300 Hz. Measures should be taken to prevent drivers and passengers from hearing this kind of noise. The present study is also a fundamental step to provide hydrodynamic pressure fluctuation data for a future acoustic wave simulations.

▼ Side channel attacks exploit physical information that leaks from a cryptographic device in order to extract secret information, such as secret keys, passwords, or instructions that may be stored inside the device. The physical information used in side-channels can be electromagnetic or acoustic emanations, timing, power consumption, or others. A widely used form of side channels relies on the analysis of power consumption. The exploited physical information in these forms of side channel attacks is the leakage traces of the power consumed during a computation. This dissertation focusses on studying power-analysis based side-channel attacks to better understand this threat to modern cryptographic devices and their implementations. The effectiveness of side-channel attacks is based on the fact that the physical leakages are dependent on the internal state of the device. This dependency is represented by a leakage model or leakage function. To better understand the leakage model in side-channel attacks, we propose to model the side channel as a communication channel in the traditional sense. This allows us to use a weighted leakage model and then to propose an L2-norm based re-weighted algorithm to further tune the leakage model. Compared to previous methods, our algorithm shows significant improvements in key recovery performance. Typically, secrets in cryptographic systems have a large number of bits, for example 128 bits in AES 128. Therefore, directly applying side-channel attacks that have proven effective for small secret with 8 or 16 bits, such as the Template Attack or the Stochastic Model, is computationally impossible. Most of the side-channel attacks typically apply a divide-and-conquer strategy to attempt to scale to larger number of bits. However, how to efficiently implement the Stochastic Model using divide-and-conquer is not obvious. This dissertation proposes two models to explore how to efficiently extend the Stochastic Model to non-linear cryptographic systems. The experimental results illustrate that our proposed methods show significant improvements in key recovery. Finally, how to efficiently exploit the samples in the leakage traces is always an important problem in side channel attacks. In the case of AES, side channel attacks are usually launched on either the first round or the last round of the AES encryption. We propose an algorithm that exploits the information during both rounds, which significantly improves the key recovery. Compared to previous methods that attempt to integrate information from multiple AES rounds, such as the Algebraic Side-Channel Attacks and the Soft Analytical Side-Channel Attacks, our method shows huge saving in computing cost and complexity due to our pragmatic implementation.

L’essor considérable d’Internet a permis l’émergence de nouveaux espaces d’échanges et d’interactions réunissant les individus à distance. Ces nouvelles formes d’interactions sociales ont conduit les chercheurs, dans le cadre des Communications Médiatisées par Ordinateur (CMO) à étudier la composante sociale des échanges en ligne, les spécificités et les conséquences de ce type d’interaction. Dans cette perspective, l’objectif de ce travail est d’examiner dans quelle mesure les spécificités des CMO – en premier lieu l’anonymat – peuvent moduler les perceptions sociales et les processus impliqués lors des interactions en ligne. Cette problématique concerne nombre de situations de communication et implique différents processus. De fait, le présent travail s’organise selon trois axes de recherche. Le premier axe aborde l’étude des perceptions groupales basées sur des appartenances circonscrites à un environnement virtuel. Le second axe s’intéresse à la modulation des perceptions de genre sur Internet, en tenant compte de la structure asymétrique de ces perceptions. Le troisième axe étudie la modulation des pressions normatives et des possibilités d’expression lors des CMO. Dans leur ensemble, ces travaux suggèrent que les CMO n’induisent pas un affaiblissement des facteurs sociaux, mais une modulation des processus en fonction des spécificités du contexte d’interaction. Les résultats de ces recherches sont discutés au regard notamment des théories de l’identité sociale, de l’auto-catégorisation et du modèle SIDE.

The growth of Internet allowed the emergence of new spaces of exchanges and social interaction between remote individuals. These new modalities of social interactions led the researchers, in the framework of Computer-Mediated Communication (CMC), to study the social component of online exchanges, characteristics and consequences of this type of interaction. In this perspective, the aim of this work is to examine how the characteristics of CMC - first anonymity - can modulate social perceptions and the processes involved in online interactions. This problem concerns many communication situations and involves different processes. Accordingly, the present work is organized in three research areas. The first part deals with the study of perceptions based on membership confined to a virtual environment. The second part focuses on the asymmetric modulation of gender perceptions on the Internet. The third part examines the influence of social norms and possibilities of expression in the CMC. Taken together, the results suggest that the CMC does not induce a weakening of social factors, but a modulation of the processes according to the characteristics of the context of interaction. The results are discussed in the light of the social identity theory, the self-categorization theory and the SIDE model.

L’objectif de cette thèse est d’étudier comment l’identification à un groupe peut conduire à de meilleures performances cognitives en s’appuyant sur la théorie de l’identité sociale (Tajfel & Turner, 1986). Cette théorie avance que l’identité sociale d’un individu repose en partie sur la comparaison entre son groupe d’appartenance et un autre groupe. La quête d’une identité sociale positive pousserait l’individu à agir pour le bien de son groupe afin de se placer dans une position avantageuse par rapport à un autre groupe. Le modèle SIDE (Social Identity model of Deindividuation Effects, Reicher, Spears & Postmes, 1995) a étendu cette théorie en considérant que l’anonymat facilite le passage de l’identité personnelle à l’identité sociale et la renforce. Notre recherche a été déclinée en trois axes. Les deux premiers ont examiné l’effet de l’anonymat et de la comparaison entre groupes sur les performances à des exercices d’informatique et de statistiques réalisés en environnements numériques. Le dernier axe a étudié les effets de l’anonymat et de la comparaison entre groupes à une tâche de production d’idées créatives en situation de coprésence. Conformément aux prédictions du modèle SIDE, les résultats ont montré que la comparaison intergroupe en situation d’anonymat active l’identité sociale des membres d’un groupe et les conduits à avoir de meilleures performances à des tâches cognitives. De plus, nous avons mis en évidence que des différences individuelles, comme le niveau de connaissances antérieures, viennent modérer les effets du modèle SIDE. Les implications pratiques et théoriques de ces résultats sont discutées, et des pistes de recherches futures sont proposées.

The aim of this thesis is to study how group identification may lead to better cognitive performance, based on social identity theory (Tajfel & Turner, 1986). This theory states that the social identity of individuals is partly based on comparison of their group with another group. The search for a positive social identity should drive individuals to act on behalf of their own group, putting them in an advantageous position compared to another group. The SIDE Model (Social Identity model of Deindividuation Effects, Reicher, Spears & Postmes, 1995) extends this theory by postulating that anonymity could facilitate the transition from personal to social identity, which is reinforced in the process. Our study was organized along three lines of research. The first two examined how anonymity and intergroup comparison affects performance on computer quizzes and statistics exercises in a web-based learning environment. The third studied the effects of anonymity and intergroup comparison on the generation of creative ideas in the presence of others. Consistent with the SIDE Model, we found that intergroup comparison under anonymity conditions activated group members’ social identity, leading to better performance on cognitive tasks. We also found that individual differences, such as prior knowledge, may moderate the effects of the SIDE model. The…

Sustainable development and its quantification procedure with specialised measurement instrument, consist a vital element for the environmental condition of the Greek island destinations; as the tourist product is a blend of ecological, social and economic sub-systems. For that reason an adapted amount of sustainable indicators is selected and a comprehensible methodological guide for their use is created, aiming to reliable measurement of selected parameters that are considered to be important for our region. We believe that using this approach, the local societies and the stakeholders involved as well, are able to understand the size of impact on the existing and mainly not renewable resources, in order to proceed with strategic planning and terms of sustainability for their future developmental course.

Η βιώσιμη ανάπτυξη και η διαδικασία ποσοτικοποίησής της με εξειδικευμένα όργανα μέτρησης, αποτελούν ζωτικό στοιχείο για την περιβαλλοντική κατάσταση των νησιωτικών ελληνικών προορισμών καθώς το τουριστικό προϊόν είναι ένα μείγμα οικολογικών, κοινωνικών και οικονομικών υποσυστημάτων. Για το λόγο αυτό επιλέγεται μια προσαρμοσμένη ποσότητα δεικτών βιώσιμης ανάπτυξης και δημιουργείται ένας κατανοητός μεθοδολογικός οδηγός για τη χρήση τους, με στόχο την αξιόπιστη μέτρηση επιλεγμένων παραμέτρων που θεωρούνται σημαντικές για την περιοχή μας. Πιστεύουμε ότι χρησιμοποιώντας αυτήν την προσέγγιση, οι τοπικές κοινωνίες και τα εμπλεκόμενα μέρη μπορούν επίσης να κατανοήσουν το μέγεθος των επιπτώσεων στους υπάρχοντες και κυρίως στους μη ανανεώσιμους πόρους, προκειμένου να προχωρήσουν με στρατηγικό σχεδιασμό και όρους βιωσιμότητας για τη μελλοντική αναπτυξιακή πορεία.

▼ With the increasing possibility of structural damage due to natural disasters, collision of vehicles, and blast and ballistic impacts, the demand for protective measures for structures is on the rise. Localised impacts are among one of the most common loading mechanisms that many modern structures undergo during their life span. Over the years, many investigations have been conducted in order to mitigate the structural damages caused by impact actions from different objects such as flying projectiles, debris, hail and collision of vehicles. Due to their unpredictability and complex nature, impact loads are considered one of the most intricate loading mechanisms to mitigate in the field of structural engineering. Engineers have been depending on high strength and high hardness materials to achieve the required resistance against such severe loadings. Better performance was achieved by either increasing the strength of the materials, or by increasing the dimensions of the structural elements. However, in recent years, attention has been tilted towards using lightweight materials in structural components in areas such as the armour industry. Due to their low density, there is comparatively high demand for lightweight materials in many industrial applications. Metal–elastomer composites can be considered as one of the main alternatives in such applications. Over the last decade, the use of elastomers as composite materials to mitigate blast loads has been extensively investigated. However, less attention has been paid to study the use of composites subjected to projectiles impacts. Therefore, in this study, aluminium–polyurea composite (metal–elastomer) has been selected as an alternative structural material to improve the performance of structures under impact loading. This thesis presents experimental, analytical and numerical investigations of aluminium–polyurea composite plates subjected to low and high velocity projectile impacts. The research has been divided into three main parts: (a) an experimental study of material behaviour under different strain rate loadings, (b) experimental, analytical and numerical investigation of aluminium–polyurea composite plates subjected to low velocity impacts, and (c) a comprehensive study of the behaviour of aluminium–polyurea composite plate systems subjected to high velocity projectile impacts. Each section consists of two peer reviewed journal papers that have either been published or are under review in international engineering journals. Over the years, aluminium alloys have been considered as a possible partial substitute for structural steel. Aluminium alloys AA5083-H116 and AA6061-T656 have been investigated for their behaviour under different strain rates, ranging from 10-3/s to 104/s. Aluminium alloy AA5083-H116 was selected as the base material in the formation of the composite in this study. With the advancement of alloying techniques, the manufacturers have been able to produce…
