Steering Reversals as a Measure of Driver Performance and Steering Task Difficulty

A review is made of past work in which steering reversal rates were used as a measure of driver performance. The data from two previously reported experiments carried out in a controlled situation, are used to compare steering reversal rates with other performance measures. It is shown that, while steering reversal rates correlate with other measures of control frequency, they do not necessarily correlate with measures of absolute steering performance. This result is consistent with the view that frequency characteristics provide a measure of steering task difficulty rather than steering performance. It is shown that, when considering steering task difficulty, care must be taken to differentiate between the difficulty imposed by the task constraints and the factors which affect the driver's ability to maintain a level of performance commensurate with those constraints.
A neural network approach for helicopter airspeed prediction

Abstract : Conventional pitot-static airspeed measurement systems do not yield accurate measurements when aircraft speed is below 40 knots. Recent studies have demonstrated that neural network approaches for predicting airspeed are quite promising. In this thesis, a back-propagation neural network is used to predict the airspeed of UH-60A and OH-6A helicopters in the low speed environment. The input data to the neural networks were obtained using the FLIGHTLAB flight simulator. The results obtained by flight simulation were validated by comparison to results of a previous study of the UH-60A helicopter based on actual flight data. The results of the work performed for this thesis show that at sea level the UH-60A low airspeed can be predicted with an accuracy of +/- 0.71 knots and +/- 0.88 knots for out of ground effect and in ground effect conditions respectively. OH-6A analyses were performed at two pressure altitudes. At sea level the OH-6A airspeed can be predicted with an accuracy +/- 0.75 knots when the aircraft is out of ground effect and +/- 0.88 knots when the helicopter is in ground effect. At a pressure altitude of 6000 feet OH-6A airspeed can be predicted with an accuracy of +/- 0.64 knots for both flight conditions.
A Downhill Grade Severity Rating System

A grade severity rating system was developed as a means for reducing the incidence and severity of truck accidents on downgrades. The ultimate result is a roadside sign at the top of each hill. The sign is tailored to the individual hill and gives a recommended maximum speed (to be held constant for the entire grade descent) for each of several truck weight ranges. This concept represents a major step forward in terms of grade descent safety because it tells the driver what to do directly, rather than giving him information which still requires evaluation under different loading conditions.
Modeling and Quantification of Acoustic Damping Induced by Vortex Shedding in Non-Compact Thermoacoustic Systems

This paper presents a methodology to compute acoustic damping rates of transversal, high-frequency modes induced by vortex-shedding. The acoustic damping rate presents one key quantity for the assessment of the linear thermoacoustic stability of gas turbine combustors. State of the art network models — as employed to calculate damping rates in low-frequency, longitudinal systems — cannot fulfill this task due to the acoustic non-compactness encountered in the high-frequency regime. Furthermore, it is yet unclear, whether direct eigensolutions of the Linearized Euler Equations (LEE), which capture the mechanism of vortex shedding, yield correct damping rate results constituted by the implicit presence of acoustic as well as hydrodynamic contributions in these solutions. The methodology’s applicability to technically relevant systems is demonstrated by a validation test case using a lab-scale, swirl-stabilized combustion system.
Information Theory for Risk-based Water System Operation

Operational management of water resources needs predictions of future behavior of water systems, to anticipate shortage or excess of water in a timely manner. Because the natural systems that are part of the hydrological cycle are complex, the predictions inevitably are subject to considerable uncertainty. Still, definitive decisions about e.g. hydropower reservoir releases or polder pump flows have to be made looking ahead into the uncertain future. This demands risk-based approach, in which, ideally, all possible future events should be considered, along with their probabilities that represent the information and uncertainty available at the time of decision. The thesis deals with water, but the flows studied are mostly those of information. Like the flow of water, also information flows obey certain fundamental laws. These are the laws of Information Theory, which also provide guidelines for developing models, handling data, and designing statistical procedures to make predictions and decisions. The information-theoretical perspective used in the thesis leads to the conclusion that predictions should necessarily be probabilistic and should be evaluated using a relative entropy measure, of which an intuitive decomposition into three components is presented. Other chapters in the thesis deal with the use of model predictive control and stochastic dynamic programming for operational water management, the time-dynamics of information, generation of weighted ensemble forecasts that balance uncertainty and information, and a perspective on data compression as philosophy of science. Recommendations for practice and further research indicate that entropy has a bright future, not only as an ever-increasing thermodynamic measure, but also as an information-theoretical measure of uncertainty that is useful in any field where predictions and decisions have to be made in a context of complex and largely unobservable systems.

ABSTRACTIslamic education needs to transform various kinds of core policies in the body of Islamic education itself which are considered capable of answering the challenges and demands. Islamic education in the face of the Industrial Revolution Era 4.0 is expected to be able to bring a positive impact in all walks of life of society, religion, nation and state, not least in the field of Islamic education itself. The era of revolution 4.0 has been able to give birth to a new phenomenon that is considered very disruption so that it demands the world of Islamic education to innovate and become competent competitors. The reality that is happening now, graduates of Islamic education are now faced with new challenges, demands, and needs that are different from previous generations. So it needs to be carried innovations to the system, governance, curriculum, human resource competencies, facilities and infrastructure, culture, work ethic, commitment to change, etc. These things need to be done and get special attention by policy makers in Islamic education. If this is ignored, then Islamic education will be crushed, increasingly left behind and abandoned by its followers. Therefore, concrete steps are needed for Islamic education to be able to remain competitive in this era of disruption. The solutive step offered is to be able to integrate and keep up with changes and developments in technology today for the realization of modern Islamic education and global competitiveness.
REVIEW OF THE NONLINEAR BIODYNAMIC RESPONSES OF THE SEATED HUMAN BODY DURING VERTICAL WHOLE-BODY VIBRATION: THE SIGNIFICANT VARIABLE FACTORS

The consistent finding of a nonlinearity in the human body apparent mass has gradually received more attention when modelling biodynamic responses of the human body. However, the factors causing the nonlinearity and the extent of the nonlinearity are not yet understood. Investigators have mainly speculated on causality of the nonlinearities rather than designed experiments to test hypothetical explanations for the nonlinearity. This paper aims to identify variables governing the nonlinear responses of the seated human body during vertical whole-body vibration. The apparent mass data and experimental conditions from six of the more relevant studies are compared. Explanations of the mechanisms controlling nonlinear behaviour are also compared. The dominant variables are classified as: posture, muscle tone, dynamics of buttocks tissue, and geometric nonlinearity.
Mapping the pre and post seismic crustal stress heterogeneity analogous to 2016, Mw 7.8, Kaikoura quake, New Zealand

Heterogeneity of pre and post seismic stress states associated to any earthquake play a primary role in understanding the earthquake mechanism and hazard assessment of a seismically dynamic region. The Mw 7.8, November 14, 2016 Kaikoura, New Zealand earthquake offer an unprecedented possibility to observe the heterogeneity in stress field over a very complex fault system wherein subduction zone converges with the strike slip faults system. Here we report the pre and post seismic stress field asperity first time in terms of spatial and temporal variations of b-values associated to the Kaikoura main-shock. Pre seismic spatial disparity of b-value indicates the existence of two prominent low b-value clusters, one towards southwest closer to the epicenter and other to the north of the rupture zone. During co seismic period, owing to the stress release near the epicentral area, the pattern of prominent low b-value pattern has become negligible in the post seismic period. However, the pattern of low b-value in the north of the rupture zone remains similar in the post seismic period indicates the unreleased strain energy in the province. The temporal evaluation of the earthquakes frequency magnitude distributions over a period of two decades also showed an analogous pattern that the b-values were decreased considerably before the large earthquakes in the expanse, which could spawn a larger future earthquakes in the vicinity.

Novel Pulse-width Modulation Strategy to Minimize the Switching Losses of Z-Source Inverters

Abstract This article proposes a novel pulse-width modulation strategy to minimize switching losses of the Z-source inverter. The Z-source inverter has different pulse-width modulation patterns unlike the conventional voltage source inverter. Shoot-through states have been inserted within the zero states of the traditional pulse-width modulation patterns of a voltage source inverter to boost DC input voltage. Thus, the Z-source inverter has six active states, two zero states, and additional shoot-through states differentiating the Z-source and conventional voltage source inverters. The currents flowing through the switches of the Z-source inverter are larger than those of the conventional voltage source inverter, because Z-network currents must flow through the switches during the shoot-through states. Therefore, shoot-through currents increase the total switching losses of the Z-source inverter. In this article, switching losses of the Z-source inverter with the existing pulse-width modulation strategy are analyzed in detail. Then, new modulation signals of the Z-source inverter are introduced to produce unique pulse-width modulation patterns that minimize the switching losses of the Z-source inverter. The switching losses of the Z-source inverter with both pulse-width modulation strategies are simulated and compared. In addition, an experimental system has been built and tested to verify the effectiveness of the proposed strategy.
Childhood, Play and School: A Literature Review in Australia

Around age three, First Nations children in remote communities in Australia undertake a major transition from the home to formal schooling. This very important period of child development is typically monitored by non-First Nations educators. Yet these educators typically know little about First Nations child development of children aged birth to seven. The purpose of this review is to demonstrate the importance of describing the process of acquiring social and cultural practices that enable a child to become a dynamic, knowledgeable participant in a First Nations context from a strengths perspective.
Evaluation of In-Structure Shock Prediction Techniques for Buried RC structures

Abstract : The analysis of buried structures designed to resist blast loading is a continuing problem in the area of engineering mechanics. The complex structural dynamic of the problem, coupled with the uncertainties of soil structure interaction, make this a difficult challenge. Even if the structure itself is designed to survive the expected dynamic loads, the shock environment inside may be severe enough to harm personnel or equipment. A thorough understanding of the expected shock environment is therefore needed to design ways to reduce this damage. The objective of this study was to conduct and evaluate in-structure shock calculations for buried reinforced concrete structures under dynamic loads from buried conventional explosives. Of primary importance was the evaluation of two dimensional explosives. Of primary importance was the evaluation of two dimensional (2-D) finite-element analysis techniques applied to this complex three dimensional problem. Two personal computer based, 2-D finite-element programs, were evaluated for application to this problem.
Lobanoviella andreyi, new genus and species of Lobanoviellini trib. nov. in the subfamily Palophaginae (Coleoptera, Megalopodidae) from the Eocene Baltic amber, with discussion of similarity with Phloeostichidae

ABSTRACT Lobanoviella gen. nov. (type species: Lobanoviella andreyi sp. nov.), for which a new tribe Lobanoviellini trib. nov. is proposed in Palophaginae, Megalopodidae, is described from Baltic amber. The new tribe differs from Palophagini sensu stricto in the head with rather long anterior part before eyes, lack of distinct anterior emargination of eyes, three apical antennomeres flat and dilated, elytra coarsely punctate to coarsely tuberculate and tarsi pseudotrimerous (4-4-4 with lack of true tarsomere 2). The described representative is the first fossil record of Palophaginae. A probable host plant of the new fossil species is discussed. Comparison of the new genus with structurally similar modern members of the family Phloeostichidae is made and it is shown that the attribution of Pleuroceratos Poinar et Kirejtshuk, 2008, as a member of Sphindidae is correct.
Water Distribution from Medium Pressure Sprinklers

Experiments enabling a quantitative analysis of the effect of various factors on the interrelationships between sprinkler drop size distribution, drop velocity, and distribution pattern of the water on the ground, indicate that operating pressure is the most important factor. Higher pressures yield longer ranges, finer drops, and more even distribution. The advantages of a single nozzle may be realized by having it act alternately as a range-nozzle and distribution-nozzle through the insertion and extraction of a pin from the jet. Advantages and disadvantages of varying factors must be considered for each particular purpose.
A stabilization approach for a novel chaotic fractional-order discrete neural network

unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract. This paper aims to make a contribution to the topic of the stabilization of chaotic dynamics in fractionalorder discrete systems by presenting a novel three-dimensional fractional-order discrete neural network formulated by the h-fractional difference operator. A novel theorem is illustrated with the aim of stabilizing the chaotic trajectories of the three-dimensional fractional-order discrete neural network at zero through proposing a quite simple linear control laws. Finally, certain simulation results are carried out to highlight the effectiveness of the stabilization approach proposed herein.
Making sense of the organisation from the front line : the call centre context

Sensemaking is a key concept supporting managerial and organisational cognitive research, and the analysis of various intervening processes that mediate how organisational members simplify and make sense of their environments. This study has directly responded to the challenge set by researchers to extend the utility of the sensemaking concept to contexts other than management. Here it was applied in the context of the United Kingdom call centre sector, where concerns have been expressed regarding a variety of key working practices that have been reported to be less than desirable, and focused upon the call centre front line worker. Reflecting a number of recent methodological debates, the study applied a multidisciplinary approach, and the employment of cause mapping data elicitation procedures. The research methodology developed enabled the collection of 200 cause maps across 5 organisations, spanning public and private sectors, in a manner that was meaningful for study participants and sufficiently rigorous to allow comparisons to be made between individual maps and across various subgroups. A variety of situational factors and individual differences variables were taken into consideration in terms of their potential impact upon, and ability to be influenced and shaped by, the processes of sensemaking. It was found that the various attempts to institutionalise call centres into an industry has not yet penetrated the lower reaches of the organisations in this study, and numerous additional insights were revealed regarding the differences in patterns of sensemaking across organisations and various sub-groups. The study has provided insights ultimately enhancing our understanding of the processes required to improve the working conditions of such front line employees. Management and employee relations were particularly salient issues for this study population. However, the variance in sensemaking revealed in this study implies that the realities of management and employee may be quite different, with these multiple realities potentially leading to fundamental misconceptions between the two parties. This has implications in terms of a wide range of organisational factors, for example job design and performance measurement. More attention is now required to take account of the sensemaking of non-managerial populations who, in and beyond the call centre context, make up the largest part of almost any contemporary work organisation.
