Analyses of Vehicle Trajectories When Leaving the Traveled Way on Curved, Superelevated Road Sections

The curvature and surface slope are known to affect vehicle dynamics and influence trajectories. On curved roadway sections, the vehicle can leave the road at a sharper angle and with superelevation the vehicle may have greater vertical force components. Consequently, impacts with roadside barriers could potentially result in a higher impact severity. The objective of this effort was to apply vehicle dynamics tools to assess the trajectories of vehicles leaving the traveled way on curved, superelevated roadway sections. The intent was to develop a better understanding of the influence of various roadway curvatures, superelevation, and shoulder or roadside designs on these trajectories to develop recommendations for effective barrier features and placement in these situations. The analyses considered two types of vehicles, six roadway curvature and superelevations rates, three impact angles, and three speeds. Data is presented comparing changes in roll, pitch, and yaw for vehicles on a roadway departure trajectory. Normalize trajectory plots were used to the potential effectiveness of three types of barrier relative to override and underride. Graphs indicating effective placement locations were generated for the three barrier types. Tabular summaries of the relative effectiveness measures are also provided. Efforts continue on this research to develop recommendation for the selection and placement of barriers on curved, superelevated roadway sections.
Development of A Haptic Steering System for a Low Cost Vehicle Simulator using Proving Ground Test Data

A haptic steering system which reflects steering reaction torque has been developed for a fixed base vehicle simulator. The haptic steering system consists of a steering effort sensor, MR-clutch, AC servo motor and controller. In order to generate realistic steering torque feel to driver and at the same time to meet real-time simulation requirement, 3D torque map is constructed by experimental data and torque generation algorithm using the torque map has been also developed. 3D torque map is constructed using curve fitting and interpolation of the measured values of the steering angle, velocity and steering torque from actual slalom test on the proving ground. In order to carry out performance test of the developed haptic steering system, a fixed based vehicle simulator is constructed by integrating real time vehicle dynamics module, VR-video/audio module, and the haptic steering system. Steering torque and steering angle curves have been obtained from virtual testing in the vehicle simulator and performance of the haptic steering system has been evaluated.

Technology support for high-throughput processing of thin-film CdTe PV modules: Annual technical report, Phase 1, 1 April 1998--31 March 1999

This report describes work performed by First Solar, L.L. C. , during Phase 1 of this 3-year subcontract. The research effort of this subcontract is divided into four areas: (1) process and equipment development, (2) efficiency improvement, (3) characterization and analysis, and (4) environmental, health, and safety. As part of the process development effort, the output of the pilot-production facility was increased. More than 6,200 8-ft{sup 2} CdS/CdTe plates were produced during Phase 1--more than double the total number produced prior to Phase 1. This increase in pilot-production rate was accomplished without a loss in the PV conversion efficiency: the average total-area AM1.5 efficiency of sub-modules produced during the reporting period was 6.4%. Several measurement techniques, such as large-area measurement of CdS thickness, were developed to aid process improvement, and the vapor-transport deposition method was refined. CdTe thickness uniformity and reproducibility were improved. From a population of more than 1,100 plates, the mean standard deviation within a plate was 7.3% and the standard deviation of individual-plate averages was 6.8%. As part of the efficiency-improvement task, research was done on devices with thin-CdS and buffer layers. A cell with 13.9% efficiency was produced on a high-quality substrate, and higher than 12% efficiency was achieved with a cell with no CdS layer. A number of experiments were performed as part of the characterization and analysis task. The temperature dependence of CdTe modules was investigated; the power output was found to be relatively insensitive (<5%) to temperature in the 25 to 50 C range. As part of the characterization and analysis task, considerable effort was also given to reliability verification and improvement. The most carefully monitored array, located at the NREL, was found to have unchanged power output within the margin of error of measurement (5%) after 5 years in the field. The first round of National CdTe Team stability tests were concluded. One back-contact formulation resulted in cells that increased in efficiency as a result of 9,700 hours of light soaking. As part of the environmental, health, and safety task, an emissions survey was performed for the pilot-production facility. For production of 360 modules/day, it was predicted that the cadmium emissions would be only 0.015% of the level that would require any permitting; however, methanol emissions may require permitting if anticipated process changes are not implemented. Process improvements in edge delete, CdS material preparation, waste compaction, CdCl{sub 2}-vapor collection, and wastewater treatment were made, resulting in reduced costs, reduced emissions, and improved operator safety.

Simulation of FA and DDT in a channel with repeated obstacles with an under-resolved mesh

Lee et.al. [1] and Lee and Moen [2] have described different regimes of high speed flame propagation in obstructed channels. Flame acceleration may lead to three different regimes, choked regime, quasidetonation and CJ-detonation. In quasi detonation DDT occurs but the detonation fails due to the following interactions with obstructions. Experiments with flame acceleration and DDT in obstructed channels has been presented by several authors [1, 2, 3, 4, 5]. Gamezo et.al. [6] has presented simulation results for channels with repeated obstacles with one step Arrhenius reaction rate. The flame acceleration in obstructed channels are caused by instabilities such as Rayleigh-Taylor, Richtmyer-Meshkov and Kelvin-Helmholtz, flame-shock interaction and flame-vortex interaction. Shock focusing and Machreflections cause transition to detonation. A comprehensive review of flame acceleration and DDT in channels is written by Ciccarelli and Dorofeev [7]. The study of simulations of flame acceleration and DDT with an under-resolved mesh is motivated by having the ability to predict DDT and fast flames in large geometries or to get simulation results within a short time. Models for sub-grid behavior of the flame-flow field interaction is important for describing the flame acceleration since the flame front is thinner than the computational mesh size. This paper describes some of the validation of a simulation codes ability to predict DDT with an under-resolved mesh.
The Tribes We Lead: Understanding the Antecedents and Consequences of Brand Evangelism Within the Context of Social Communities

Brand evangelism has significant potential to impact loyalty, thereby making the construct an important point of interest for practitioners and researchers alike. This study attempts to augment existing literature by demonstrating how antecedent constructs such as trust and sentiment operate in unique and distinctive ways when mediated by brand evangelism, especially as it relates to two very different outcome variables in attitudinal and behavioral loyalty. While brand evangelism is found to be a mediator for the impact of sentiment on loyalty, it interestingly does not seem to be a mediator for the impact of trust on loyalty.
Literature Contributions of a Pediatric Cardiologist to Adult Congenital Heart Disease - Part III

The prevalence of congenital heart defects (CHDs) in adults has increased during the last few decades such that now there are more adults with CHD than children. Advances in the diagnosis and management of CHD in children has resulted in this phenomenon. This review indicated that transcatheter methods are successful in relieving obstruction associated with coarctation of the aorta, pulmonary stenosis and aortic stenosis. With regard to cyanotic CHD, the majority of patients presenting in adulthood are likely to be those that have had corrective or palliative surgery during infancy and childhood, although on rare occasion uncorrected defects may present for the first time in adulthood. Pathophysiologic effects of right to left shunt associated with cyanotic CHD are reviewed. Brief description of the anatomy of the most common cyanotic CHDs, namely, tetralogy of Fallot, transposition of the great arteries, tricuspid atresia, total anomalous pulmonary venous connection, and truncus arteriosus was presented followed by a discussion of management strategies of the residual defects. Adults who did not have surgical correction in childhood should undergo surgical correction, but they may have a higher risk than that seen in children diet, parental albumin administration and replacement of
Optimization of dynamic sequential test strategy for equipment health management

Testing is the premise and foundation of realizing equipment health management (EHM). To address the problem that the static periodic test strategy may cause deficient test or excessive test, a dynamic sequential test strategy (DSTS) for EHM is presented. Considering the situation that equipment health state is not completely observable in reality, a DSTS optimization method based on partially observable semi-Markov decision process (POSMDP) is proposed. Firstly, an equipment health state degradation model is constructed by Markov process, and the control limit maintenance policy is also introduced. Secondly, POSMDP is formulated in great detail. And then, POSMDP is converted to completely observable belief semi-Markov decision process (BSMDP) through belief state. The optimal equation and the corresponding optimal DSTS, which minimize the long-run expected average cost per unit time, are obtained with BSMDP. The results of application in complex equipment show that the proposed DSTS is feasible and effective.
Long-Life Slab Replacement Concrete

This research was initiated following reports of high incidence of cracking on Florida Department of Transportation (FDOT) concrete pavement replacement slab projects. Field slabs were instrumented for data acquisition from high-early-strength concrete pavement replacement slabs placed on projects funded by FDOT. Data were collected for three slabs located in Jacksonville, Florida, and Gainesville, Florida. A battery of laboratory tests was simultaneously conducted on the FDOT-approved concrete mixture designs used in the instrumented field slabs in addition to mixtures with variable chloride-based accelerator dosage. Temperature and strain data, as well as physical and thermal data, were acquired from slabs from the construction projects. The physical and thermal data acquired from the field were used for modeling description and verification. Subsequent to the field testing and data acquisition, the slabs were inspected for the presence of cracking. Laboratory testing included as-received materials characterization, heat of hydration measurements using isothermal and semi-adiabatic calorimetry for temperature rise assessment, and strength maturity curves for strength assessment. Using ConcreteWorks and HIPERPAV III, the findings indicated that adherence to the approved mixture design is critical. High placement temperatures and concrete placement during the day increased concrete cracking potential. Field additions of accelerator in excess of the approved mixture design were also found to increase the cracking potential.
Optimization on cell disruption of E. coli BL21-AIexpressing recombinant bromelain

Recent advancements in recombinant DNA technology proved to be a promising and effective approach for more sustainable large scale productions of many therapeutic proteins. Nevertheless, since this approach involves expression of proteins in a nonnative host microorganism, the overall production processes are not straight-forward due to several common challenges, such as protein degradation, especially during cell disruption stage. As the process has been subjected to both protein and host-specific, a systematic process conditioning for maximal production of recombinant protein is therefore required. In this study, a simple approach to determine optimal conditions for cell disruption using ultrasonication to isolate recombinant bromelain from E. coli BL21- AI is reported. Suspension cells were lysed using ultrasonication which transmit sound wave in other to break the cell wall. An optimized condition was obtained by response surface methodology (RSM). A three factor face-centered central composite design (FCCD) was applied to obtain the optimal process conditions consisting of amplitude, cycle and bursting period. The prediction model was further validated. Therefore, under the optimal conditions, having 20% amplitude, 0.5s cycle, and 1 minute bursting period in three times process, the specific enzyme activity of the recombinant
Modelling Embodied Appraisal in Humanoids : Grounding PAD space for Augmented Autonomy

The work presented in this dissertation investigates the problem for resource management of autonomous robots. Acting under the constraint of limited resources is a necessity for every robot which should perform tasks independent of human control. Some of the most important variables and performance criteria for adaptive behavior under resource constraints are discussed. Concepts like autonomy, self-sufficiency, energy dynamics, work utility, effort of action, and optimal task selection are defined and analyzed as the emphasis is on the resource balance in interaction with a human. The primary resource for every robot is its energy. In addition to the regulation of its “energy homeostasis”, a robot should perform its designer’s tasks with the required level of efficiency. A service robot residing in a human-centered environment should perform some social tasks like cleaning, helping elderly people or delivering goods. Maintaining a proper quality of work and, at the same time, not running out of energy represents a basic two-resource problem which was used as a test-bed scenario in the thesis. Safety is an important aspect of any human-robot interaction. Thus, a new three – resource problem (energy, work quality, safety) is presented and also used for the experimental investigations in the thesis.The main contribution of the thesis is developing an affective cognitive architecture. The architecture uses top-down ethological models of action selection. The action selection mechanisms are nested into a model of human affect based on appraisal theory of emotion. The arousal component of the architecture is grounded into electrical energy processes in the robotic body and is modulating the effort of movement. The provided arousal mechanism has an important functional role for the adaptability of the robot in the proposed two- and three resource scenarios. These investigations are part of a more general goal of grounding highlevel emotion substrates - Pleasure Arousal Dominance emotion space in homeostatic processes in humanoid robots. The development of the architecture took inspiration from several computation architectures of emotion in robotics, which are analyzed in the thesis.Sustainability of the basic cycles of the essential variables of a robotic system is chosen as a basic performance measure for validating the emotion components of the architecture and the grounding process. Several experiments are performed with two humanoid robots – iCub and NAO showing the role of task selection mechanism and arousal component of the architecture for the robot’s self-sufficiency and adaptability.

Modelling of factors impacting adoption of precast concrete systems

Construction technology utilizing prefabricated concrete elements is known as a precast concrete system. In Western countries, this system has been widely used in constructing bridges, office buildings and residential buildings. A precast concrete construction system provides the advantages of construction effectiveness, high levels of quality control, saving of construction time, minimisation of skilled labour, reduced manpower requirements on site, and saving in formwork requirements when compared with the traditional construction method (cast-in-place concrete). In Thailand, cast-in-place is the traditional construction system that has been mostly used to this point. Precast concrete floor slabs are the only a prefabricated elements used widely in Thailand. Only a few parties in the Thai construction market have adopted fully precast concrete systems. However, many factors have an impact on the adoption of precast concrete system. This paper presents and analyses a conceptual model that accommodates the numerous factors impacting the effectiveness of the adoption process. The results of a survey of 160 construction industry professionals in Thailand are presented and the significant factors which impact the adoption of precast concrete systems are determined through statistical analysis. The paper concludes with an analysis of the significant factors in the adoption of precast concrete elements and system.

Waste glycerol derived bio‐propanol as a potential extender fuel for compressed ignition engine

In recent years there has been a significant rise in crude glycerol generation due to the booming biodiesel industries. Despite having immense benefits, the presence of poisonous methanol and fatty acids, glycerol is treated as a waste by‐product of biodiesel. In the present study, investigations have been carried out on utilizing the potential of glycerol derived bio‐propanol as an extender fuel with diesel/gasoline blends. Test fuels containing ternary blends of diesel/gasoline/bio‐propanol in different volume concentrations were prepared. The crude glycerol was procured from transesterified Kusum (Schleichera oleosa) oil. The physicochemical properties, along with stability and homogeneity of the test fuels were evaluated as per ASTM/EN standards and compared with the neat diesel. To study the effect of fuel properties on atomization process, the sauter mean diameter of the test fuels were observed using Malvern spraytec test. The engine performance, combustion and emission characteristics of a single‐cylinder diesel engine fuelled with different test fuels were also conducted. Due to the enhancement in mixing rate promoted by low cetane fuels, the ignition delay and heat release rate was higher than diesel. Moreover, the results also reveal upto 5% increase in brake thermal efficiency and a significant reduction in harmful exhaust emission with an increase in the gasoline and bio‐propanol share in the blend. The oxide of nitrogen (NOx) emissions was also lower than diesel for all the fuel blends. In comparison to diesel, the maximum reduction in NOx, HC, CO and smoke emissions is 7.4%, 33.3%, 55.7%, and 17.2%, respectively, for D40:G30:P30 fuel blend.
