Switching Behavior of USCi ’ s SiC Cascodes

Trench JFET Structure Figure 1 shows the schematic cell structure of the trench JFET. The low on-resistance derives from the vertical channel that repeats with a high cell density, creating a short path between the source and drain contacts via the channel and drift regions. The drift region doping and thickness are determined by the desired voltage rating. The trench JFET does not contain a built-in body diode, or any parasitic NPN transistor. Its controlling channel is formed by pn-junction and is purely vertical, having no critical gate-oxide or any surface conduction path. As illustrated in Figure 1, a pn-junction diode is formed between the gate-source and the gate-drain regions. By controlling the opening width of the vertical channel, a normally-on JFET can be implemented. The normally-on JFET typically has a threshold voltage (VTHJ) of -6V. To achieve the rated blocking capability, usually a reverse bias of -15V to -20V is applied between the gate and source contacts [1], which is sufficient to deplete the channel region and form a potential barrier between the drain and source. If a drain voltage is now applied, the JFET will block this voltage by depleting the drift region.

Energy-Budgeting Sensor Networks with Renewable Energy Sources

Energy-aware scheduling, or energy budgeting, is an evolving research area of energy-harvesting sensor networks. This thesis will contribute to this field in three ways. Firstly, models for predicting the remaining energy of supercapacitors, which are frequently used for energy storage in harvesting devices, are developed and assessed. Secondly, existing prediction algorithms for future energy inflow are evaluated and enhanced to achieve an increased prediction horizon. Thirdly, an energy-aware scheduler will be devised that plans node and network tasks with respect to present and predicted future energy resources of individual nodes in the network.
The performance of new early maturing pro-vitamin A maize (Zea mays L.) hybrids in the derived savanna agro-ecology of Nigeria

Maize (Zea mays L.) is a staple food for millions of people across the globe, and it supplies more than 30% of total dietary calories. However, the normal endosperm lacks a sufficient quantity of the nutritive precursor of vitamin A. To achieve food security and avert malnutrition, there is a need to adopt the cultivation of the early multiple stress-tolerant pro-vitamin A maize hybrid. The objective of this study was to assess the agronomic performance and yield of the newly developed maize hybrids. Fifteen improved maize hybrids and one commercial hybrid used as a local check were evaluated in a randomized complete block design with two replications for two years at the Ladoke Akintola University of Technology Teaching and Research farm in Ogbomoso, Nigeria. Hybrids exhibited significant variation (P < 0.01) for grain yield, number of days to anthesis and silking, ear height and husk cover. Across the years, the grain yield of hybrids ranged between 4,780.8 kg ha? 1 (PVAEH-19) and 7,886.9 kg ha? 1 (PVAQEH-1), with a mean of 6,354.2 kg ha? 1. PVAEH-15 ranks the best on the basis of superiority in grain yield, early flowering and tight husk cover. Fourteen hybrids out-yielded the local check (4,947.2 kg ha-1), and five hybrids had a significant (P < 0.05) yield advantage of > 26% over the local check. The consistent performance of PVAEH-15 and PVAEH-16 in the two years of evaluation indicates potential for the adaptability of the hybrids to the agro-ecology. Farmers? adoption of these maize hybrids will boost maize production and prevent malnutrition in the derived savanna agro-ecology of Nigeria.
Risk Analysis for Exploring the Opportunities in Cloud Outsourcing

Context: Cloud Outsourcing is a new form of outsourcing which is not more under implementation and yet to be implemented. It is a form of outsourcing in which software organizations outsource the work to e-freelancers available throughout the world using cloud services via the Internet. Software organizations handovers the respective task to the cloud and from the cloud e-freelancers undertake the development of task and then return back the finished task to the cloud. Organizations recollect the finished task from the cloud and verify it and then pay to the e-freelancer. Objectives: The aim of this study is to identify the sequence of activities involved during the entire process of cloud outsourcing and to find out the risks which are likely to be occurred during the implementation of this process. To prioritize the elicitated risks according to their probability of occurrence, impact and cost required to mitigate the corresponding risk. Methods: Data is collected by literature review and then the data is synthesized. On the other side interviews with practitioners are conducted to know the activities involved and to find out the risks that are likely to be occurred during the implementation of cloud outsourcing. After this, a survey is conducted in order to prioritize the risks and a standard risk analysis is conducted to know the risks which are likely to be occurred. Literature review is done using four databases including the literature from the year 1990 to till date. Results: Totally we have identified 21 risks that are likely to be occurred and 8 activities so far. By performing risk analysis we have presented the risks, which should be considered first and relevant counter measures are suggested to overcome them.
Organizational Change and Dynamics of Control: An Analysis of Italian Call Center Workplace

The main goal of the paper is to interpret the concept of organizational change in the perspective of critical management studies, by analyzing both the discourses and the control practices used by management. We aim at denaturalize the concept of change related to transition from a bureaucratic model to a professional (post-bureaucratic) model of the call centers organizational design, showing how these discourses and practices reproduce control systems. For this purpose, two cases study of call center outsourced industry are presented. On one hand, we emphasize the bureaucratic nature of call center A associated with standardization of processes and products and where work is highly controlled and routinised. On the other hand, we observe a different image of call center: call center B can be described as a place where work is customized, workers are considered key resources with higher competences and skills that are able to give customers unique solutions and to give answer to complex questions. We suggest that these “new practices” and “new organizational approaches” are merely illusions of change. We argue that in professional model (call center B), control institutionalized through technology is strengthened and deepened by the use of post-bureaucratic control in shaping organizational behaviors, reproducing a Panopticon structure both in terms of electronic surveillance and in terms of behavioral (self) regulation and discipline.
Spatial Analysis of Pre-Hospital Emergency Bases in Disasters in Tehran Province, Iran

INTRODUCTION: Tehran is always exposed to various dangers due to its high population density. A geographic information system (GIS) can be very useful for reducing the financial and human burden caused by accidents, disasters, and diseases. METHODS: This field study was performed using a practical and descriptive research method. The pre-hospital emergency bases in the east of Tehran province and all the emergency bases covered by Shahid Beheshti University of Medical Sciences in disasters were evaluated as a case study. The population of these cities amounted to 1,149,485 people and included cities in the east of Tehran province, Iran, including Damavand, Firoozkooh, Pakdasht, Pishva, Qarchak, and Varamin. FINDINGS: Rational maps were created and analyzed in the areas where emergency bases were located using ArcGIS software, as well as analysis of regions, distances, point density, and a combination of these factors. Regarding the standards and indicators, it was determined that the Disaster and Emergency Medical Management Center needs to have130 emergency medical technicians, 23 ambulances, and one ambulance bus to equip the exiting emergency bases according to the standard pre-hospital regulations. Other requirements in this regard include the replacement of worn-out ambulances with new ones, construction of two emergency bases in Qarchak, Tehran, Iran, and three emergency bases in Pakdasht, Tehran, Iran, as well as the transfer of bases in the proximity of faults and flood-prone areas to safe places. CONCLUSION: Based on the obtained results, a comprehensive pre-hospital database was designed for the use of managers and officials in the occurrence of accidents, which might be used as a pilot work that can be expanded to other areas of Tehran, Iran, and other provinces in managing disasters and accidents.
Relationship between Teachers’ Perceptions Towards School Principals' Instructional Leadership Practices and Teachers’ Concerns about Teaching and Learning Innovation

The purpose of this study is to determine the relationships between secondary school teachers perceptions towards instructional leadership practices of their principals and teachers concern about teaching and learning innovation. The sample of the study consists of 350 secondary school teachers in Petaling Perdana, Selangor. The instruments were adapted from the The Principal Instructional Management Rating Scale (PIMRS) developed by Hallinger and Murphy (1985) and Stages of Concern Questionnaire (SoCQ) developed by Hall and Hord (2011). Descriptive and inferential analyses were performed to examine the relationship including frequencies, percentage, standard deviation and correlation. Data analysis indicated that there was a moderate positive correlation between teachers perceptions towards the school principal instructional leadership style and teachers concerns about teaching and learning innovation with values of r = 0.371 ** and sig 0.00 (p˂0.01). A weak relationship was found in the dimension of instructional leader's role in defining a school mission. This indicates that the principals have implemented defining a school mission dimension at weak level and significant. The finding should be given serious attention with some improvement that can be made to optimise the teachers’ concerns about teaching and learning innovation.
Objective Predictor metric of Annoyance for Hydraulic Engine Mount Cavitation

Vehicle acoustics has been found to have a direct impact on customer experience. Unexpected noises play a role in this experience. Hydraulic engine mount cavitation, the noise heard from the collapse of vapor bubbles in the mount, is considered one of those unexpected noises. During the design phase of a vehicle when an unexpected noise is found there is a need for a method to quantify how much of the noise is too much. Subjective evaluations alone are not enough due to variability from engineer to engineer. An objective way needed to be developed in order to evaluate the cavitation noise. To address this issue, an objective predictor metric of annoyance was developed. The model was developed by comparing psychoacoustic metrics to subjective ratings by means of regression analysis. Once the psychoacoustic metrics were chosen multiple regression analysis was used to develop the predictor metric. INDEX WORDS: hydraulic engine mount, cavitation, psychoacoustic metrics, regression analysis
Innovation policy and administration system in the era of post catch‐up: The case of the Roh Moo‐hyun administration's innovation policy

Summary This study analyzed the implications of changes in the innovation policy and administration system in the Roh administration and explored its limitations as well as its future development prospects. Since the Roh Moo‐hyun administration took office in 2002, Korea's innovation policy has been expanded and its position has been further elevated in the hierarchy of policies. Especially, S&T‐related agenda has emerged as a core national policy initiative and these changes showed the start of a new type of innovation policy. Various experiments tried in the Roh administration, however, showed the limitation and path dependency of the administration. Since the Lee Myung‐bak administration took office in 2008, his government carried out radical governmental reforms, including the integration and abolition of S&T‐related ministries. As a result, the government abolished the Office of the Deputy Prime Minister for Science and Technology (Ministry of Science and Technology), which was established in 2004. The government also abolished the Office of Science, Technology and Innovation (OSTI), which was established in 2004 to support the Deputy Prime Minister in the overall coordination of STI policies. In fact, all of the four Deputy Prime Ministers in the previous government were abolished. As we can see through these changes, it is difficult to expect continuity in policy implementation in Korea owing to institutional limitations such as the single presidential term. Under this institutional constraint, innovation policy and administration system tried in the Roh administration seems to be heading towards dissolution or ending up in smoke.
Identifying Law Enforcement Needs for Conducting Criminal Investigations Involving Evidence on the Dark Web

With the advent of the dark web, criminals can conduct their activities in ways that are difficult for law enforcement to discover, monitor, and investigate. This report describes the findings of an expert workshop of federal, state, and local law enforcement practitioners and researchers who explored how law enforcement agencies should conduct criminal investigations while dealing with evidence on the dark web.
Relation of Influential Parameters to Back-Flashover on the Insulators in Transmission Tower

This paper focuses on behavior of over-voltage across the cross arm and back-flashover on the insulators with different front times of lightning waveshape. The simulations and analysis are performed using Alternative Transients Program/Electromagnetic Transients Program (ATP/EMTP) to investigate both over-voltage across the cross arm and insulators. The scheme under investigations is a part of Thailand electricity transmission and distribution system. The standard of lightning voltage waveshape (1.2/50 μs) will be compared with the other lightning voltage waveshape front time (4/50 μs) in this paper. The results indicate that the front time of lightning waveshape plays an important role for the back-flashover voltage across insulator as well as the tower footing resistance and the lightning current.
Evaluating the Effectiveness of Schedule Changes for Air Traffic Service (ATS) Providers: Controller Alertness and Fatigue Monitoring Study

The Federal Aviation Administration's (FAA’s) Fatigue Risk Management Program is developing a Fatigue Risk Management System that will include science-based shift scheduling and other strategies designed to maintain air traffic controllers’ alertness over the 24-hour clock and to reduce negative impacts of fatigue on Air Traffic Control (ATC) operations. The National Aeronautics and Space Administration (NASA) was tasked with conducting research to provide up-to-date knowledge about the state of controller shift work, sleep, alertness and factors contributing to controller fatigue. To that end, the NASA research team conducted a two-pronged effort: a web-based survey of fatigue factors that was available to the entire ATC workforce and a field study that obtained objective measures of sleep, fatigue and alertness in a sample of controllers from selected facilities, including En Route Centers, Terminal Radar Approach Controls (TRACONs), and ATC Towers. During 2010, 3,268 United States ATC personnel completed the online fatigue survey. The field study resulted in complete data being obtained from 211 controllers working at 30 facilities across the country. Data consisted of 14 days of continuous sleep and activity monitoring using wrist-worn actigraphs, daily sleep and activity logs, a brief objective measure of alertness, and subjective ratings of sleepiness and workload. The purpose of the present study was to establish a quantified baseline for evaluating the impact of the FAA’s planned fatigue risk mitigation strategies. Findings also will identify factors affecting fatigue and assist in targeting and designing future research areas. Results from this study were compared to those obtained from a 1999 survey (Della Rocco et al., 2000a) and several field studies conducted by the FAA between 1995-2005 (Della Rocco & Cruz, 1995; Cruz & Della Rocco, 1995b; Della Rocco & Cruz, 1996; Della Rocco et al., 2000b; Cruz et al., 2002; Della Rocco & Nesthus, 2005; Broach & Schroeder, 2005).

Motion Analysis of an Electric Vehicle with Two Independent Drive Motors

Motion analyses are performed with the help of stability and simulation analysis, which can provide theoretical bases for applications of an electric vehicle with two independent drive motors. Compared with one-motor drive electric vehicle, the two-motor drive electric vehicle has the advantage of easy layout, simple power train and good drivability and handling characteristics. Analysis shows the method connecting armatures of two DC motors in parallel can function as mechanical differential without a steering sensor, which can simplify structure and increase reliability of the controller. Computer simulations and experiment are carried out to verify conclusions.
Estimation of weight and height of patients with primary immunodeficiency disorders and group of children with recurrent respiratory tract infections.

Background Primary immunodeficiences (PIDs) are a group of chronic, serious disorders in which the immune response is insufficient. In consequence, it leads to an increased susceptibility to infections. Up to date, there are about 300 different disorders classified in that group. There are also patients suffering from recurrent respiratory tract infections (RRTI), however that group doesn't present any abnormalities in terms of conducted immunological tests. Many factors, including medical, can have an impact on physical development of a child. Data such as birth weight and length, also weight, height, BMI during admission to the hospital were collected from 207 patients' medical histories from their hospitalization at Clinical Immunology and Paediatrics ward of J.Gromkowski Hospital in Wrocław. Investigated groups included patients with PIDs, RRTI and a control group of healthy children. Our purpose was to evaluate the physical growth of children with primary immunodeficiency (PID) and children with recurrent respiratory tract infections (RRTI) by assessment of their height and weight. All of parameters were evaluated using centile charts suitable best for the Polish population. Results The lowest mean birth weight and height was found among the PIDs patients group. Children with PIDs during hospitalization had statistically relevant lower mean weight than the control group and almost 20% of them had their height situated below 3rd percentile. No statistically relevant differences have been found between them and RRTI group. The statistically significant difference was between the nutritional status of PID patients and the control group. Conclusions There is a higher percentage of PID patients with physical growth abnormalities in comparison to healthy children. Our findings indicate a need for further investigation of immune system irregularities and their influence on physical growth of children.
The influence of vehicle shape on pedestrian ground contact mechanisms

Pedestrians struck by high-fronted vehicles suffer more severe injuries from ground contact than those struck by passenger cars, but the reasons for this are not clear. In this paper, multibody models of vehicle/pedestrian impacts for different vehicle shapes and speeds and pedestrian sizes and stances are used to analyze the kinematics of pedestrian ground contact. It is shown that patterns are identifiable, there is a correlation between bonnet leading-edge height and HIC score from ground contact and the body angle at the instant of ground contact is correlated with the HIC score. It is thus evident that there is a geometric explanation for the empirical finding that high-fronted vehicles cause more significant ground-related head injuries.
Environmental, Safety, Legal and Societal Implications of Autonomous Driving Systems

The concept of autonomous driving opens up for many opportunities but, at the same time, raises concerns and issues for discussion that need to be analyzed and penetrated before a more broad roll-out of autonomously driven vehicles on public roads can be attempted. Among the obvious potential benefits for the society are improved fuel economy, enhanced safety and reduced congestion. There are, however, also potential benefits in offering mobility to the physically challenged, reduced need for infrastructure investments, more efficient use of the urban landscape and individual benefits with more efficient use of the time spent in the car. Driving in autonomous mode opens up for using the time for other useful occupations, e.g. working, relaxing, eating, etc. Many obstacles remain before autonomous driving can be a part of transportation on public roads. In Europe an intense debate is discussing the implications of the Vienna Convention, which governs the framework for the requirements on the driver, and the legality of not having the driver in control of the vehicle. In the US, activities within the states are opening up for autonomous driving testing on public roads under certain provisions, but there is an obvious risk of causing fragmentation by creating deviating requirements. Sorting out the liability issues will be one of the major challenges before autonomous driving on public roads can be a reality. Present national laws in some countries do require a person in form of the driver to be liable in the case of an incident or a crash. For higher levels of autonomous driving, liability needs to rest with the manufacturers or another entity not in the form of a person and should be reflected in national liability legislation.
Low Dose Methotrexate Toxicity Leading to Death in the Intensive Care Unit

Methotrexate toxicity has been widely shown to cause myelosuppression but the literature demonstrating low doses of the drug causing the same issue is much scarcer. Our patient presented with severe pancytopenia which began to improve with treatment but she ultimately succumbed to a superimposed pneumonia.
