1. Kelly, Robin B. Study of necessary skill areas and perceived skill deficits in Australian educational administrators.

Degree: 1982, University of Canberra

URL: http://erl.canberra.edu.au./public/adt-AUC20060807.152031 

This field study is the result of observations of stress and disquiet among educational administrators. Two survey instruments, one to a population of A.C.E.A. members in five states and two territories of Australia, and a refined survey to administrators in two Metropolitan West Inspectorates in N.S.W. were employed. An attempt was made to look at perceived deficits, in areas considered necessary skills for educational administrators, over variables of state, sex, age, level of institution, government/nongovernment systems, status, tenure and educational administration qualifications. From the outset it was realized that the nature of the study would have to be essentially to generate directions of future specific research since there was little Australian research in the areas being surveyed. This became more obvious as data was collected and possible causes for stress, perceived deficits, and the related poor morale multiplied with each set of comments received. The only conclusion that could be unequivocal was that the areas of administrator morale, training, selection, support, style and role perception are urgently in need of in-depth research as are the effects on educational institutions of policy processes, socio-political factors and community expectations. Even with a wider literature search it becomes obvious that there is a need for researchers to rethink theory in terms of social realities and human and socio-political possibilities rather than continue building theories which have little or no effect on the education received by an Australian student in the 1980's. It is equally evident that the solution for the obvious administrator malaise and powerlessness expressed by respondents is in their own hands via a quest for excellence in education, relevance to society and socio-political understanding.

2. Lundberg, Petter. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle.

Degree: Physics, 2014, Umeå University

URL: http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-93298 

An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. Decreasing the opposing driving resistances for an operating vehicle increases its fuel efficiency: an effect which is highly valued in today’s industry, both from an environmental and economical point of view. Therefore a lot of progress has been made during recent years in the area of fuel efficient vehicles, even though some driving resistances still rises perplexity. These resistances are the air drag Fd generated by the viscous air opposing the vehicles propulsion and the rolling resistance Frr generated mainly by the hysteresis caused by the deformation cycle of the viscoelastic pneumatic tires. The energy losses associated with the air drag and rolling resistance account for the majority of the driving resistances facing an operating vehicle, and depends on numerous stochastic and ambient parameters, some of which are highly correlated both within and between the two resistances. To increase the understanding of the driving mechanics behind the energy losses associated with the complexity that is rolling resistance, a set of complete vehicle tests has been carried out. These tests were carried out on the test track Malmby Fairground, using a Scania CV AB developed R440 truck equipped with various sensors connected in one measurement system. Under certain conditions, these parameters can allow for an investigation of the rolling resistance, and a separation of the rolling resistance and air drag via explicit subtraction of the air drag from the measured traction force. This method is possible since the aerodynamic property AHDVCd(β) to some extent can be generated from wind tunnel tests and CFD simulations. Two measurement series that enable the above formulated method of separation were designed and carried out, using two separate measurement methods. One which enables the investigation of the transient nature of rolling resistance as it strives for stationarity, where the vehicle is operated under constant velocities i.e. no acceleration, and one using the well established method of coastdown, where no driving torque is applied. The drive cycles spanned a range of velocities, which allowed for dynamic and stationary analyses of both the tire temperature- and the velocity dependence of rolling resistance. When analysing the results of the transient analysis, a strong dependence upon tire temperature for given constant low velocity i.e. v ≤ 60 kmh−1 was clearly visible. The indicated dependency showed that the rolling resistance decreased as the tire temperature increased over time at a given velocity, and vice versa, towards a stationary temperature and thereby rolling resistance. The tire temperature evolution from one constant velocity to another, took place well within 50 min to a somewhat stationary value. However, even though the tire temperature had reached stationarity, rolling…
