A Fast and Precise Method for Modeling EMI Source in Two-Level Three-Phase Converter

Currently, frequency-domain electromagnetic interference (EMI) modeling has become the most commonly used method for EMI prediction and filter design. However, because of the unpredictability of the ringing effect in the present frequency-domain EMI modeling methods, the precision of the predicted EMI interference source is notably limited, which results in the inaccuracy of the system level EMI prediction. In order to achieve an accurate EMI prediction, this study presents a systematical study on the interference source of a 10 kVA three-phase bridge converter. The precise mathematical models of the common-mode and differential-mode interference source are constructed. Then, the characteristics of the multiple ringing effect, which is an important part of the interference source, are intensively analyzed. Based on the investigation of interference source, an improved interference source synthesis method is proposed. It can quickly and precisely predict the CM and DM interference source with multiple ringing effect, which can be used to achieve accurate frequency domain EMI prediction. Moreover, the multiple ringing effect is extended for IGBT parasitic parameter measuring. Instead of complicated device-level measurement, the grounding capacitance and junction capacitance can be effectively extracted through the ringing frequency measurement.
Co-Planning of Demand Response and Distributed Generators in an Active Distribution Network

The integration of renewables is fast-growing, in light of smart grid technology development. As a result, the uncertain nature of renewables and load demand poses significant technical challenges to distribution network (DN) daily operation. To alleviate such issues, price-sensitive demand response and distributed generators can be coordinated to accommodate the renewable energy. However, the investment cost for demand response facilities, i.e., load control switch and advanced metering infrastructure, cannot be ignored, especially when the responsive demand is large. In this paper, an optimal coordinated investment for distributed generator and demand response facilities is proposed, based on a linearized, price-elastic demand response model. To hedge against the uncertainties of renewables and load demand, a two-stage robust investment scheme is proposed, where the investment decisions are optimized in the first stage, and the demand response participation with the coordination of distributed generators is adjusted in the second stage. Simulations on the modified IEEE 33-node and 123-node DN demonstrate the effectiveness of the proposed model.
Effect of IoT Capabilities and Energy Consumption behavior on Green Supply Chain Integration

The Internet of Things (IoT) is the next generation of internet-connected information communication technologies (ICT). IoT typically integrates supply chain activities to enhance green supply chain performance (GSCP). Since every organization has different IoT capabilities in comparison with other organizations, GSCP can enable supply chain integration activities for enhanced performance. The implementation of an IoT system can reduce the consumption of organizational resources like energy, electricity, and time and can increase the operational speed to gain better logistics and, ultimately, improved supply chain performance. This study has developed and empirically tested the relationship between IoT capabilities, energy consumption behavior (ECB), supply chain integration, green training (GT), and supply chain practices. Such a multidisciplinary relationship has not previously been established in the literature. The proposed study can fulfill the literature gap and opens new horizons for interdisciplinary research. Data used in this study are collected through offline and online survey methods. A total number of 250 out of 400 respondents participated in the survey. Data has been analyzed through partial least square—structure equation modeling (PLS—SEM) technique. The results of this study empirically test the developed model. IoT has a positive effect on supplier integration (SI), and customer integration (CI). Furthermore, SI and CI have a mediating role between IoT and GSCP, and GT has a positive impact on GSCP. It is concluded that the implementation of IoT can integrate CI and SI to increase GSCP. GT and ECB can ultimately improve GSCP. Additionally, the use of technology and GT can motivate employees to save energy and protect the environment to increase GSCP.

Optimum Design of Power Converter Current Controllers in Large-Scale Power Electronics Based Power Systems

In a large-scale power electronic system such as a wind farm, the mutual interactions between the power converter controllers and passive components may lead to instability problems or undesired dynamic response. This paper presents an optimum parameter design procedure for the power converter controllers in a power electronic system in order to guarantee a stable operation and to guarantee an acceptable dynamic response. In the approach, first, all oscillatory modes are calculated by a multi-input multi-output (MIMO) transfer function matrix of the power system; then, a multi-objective optimization procedure based on the genetic algorithm (GA) is presented to place the modes in the desired locations in order to increase the stability margin and to improve the dynamic response. Time-domain simulations of a 400-MW wind farm in the PSCAD/EMTDC environment confirms the effectiveness of the presented design approach.
The Pharmacogenetics of Treatment with Quetiapine

Quetiapine is a second-generation antipsychotic used for the treatment of schizophrenia, depression and bipolar disorder. The aim of this traditional review was to summarize the available pharmacogenetic information on this drug and to conclude about its clinical relevance. For this purpose, bibliographic research was performed in the Pharmacogenomics Knowledge Base (PharmGKB) database. A total of 23 articles were initially retrieved, of which 15 were finally included. A total of 19 associations were observed between 15 genes, such as CYP3A4, CYP3A5, COMT or MC4R, and 29 clinical events. No associations were consistently replicated between pharmacogenetic biomarkers and clinical events, except for that between the CYP3A4 phenotype and quetiapine exposure, which was the only one considered clinically relevant. Consistently, the DPWG published a clinical guideline on this association, where dose adjustments for CYP3A4 poor metabolizers (PMs) are indicated to prevent the occurrence of adverse drug reactions (ADRs).
Optimal resource allocation for high‐order nonlinear uncertain multi‐agent systems

This article investigates the optimal resource allocation of nonlinear high‐order multi‐agent systems with coupling uncertainties. The objective is to design an output‐feedback distributed algorithm for each agent to optimize the global cost function under network constraints. The global cost function is the sum of local cost functions. The available information to design the algorithm for each agent is only its own output and cost function, the outputs of its neighbors. To address the key technical challenge arising from the uncertainties and nonlinearities of network systems, a novel distributed resource allocation algorithm is proposed using active disturbance rejection strategy. The simulation results in the economic dispatch of a smart grid validate the effectiveness of the proposed method.
Reimplementing the Wheel: Teaching Compilers with a Small Self-Contained One

We report on a one-semester compiler construction course based on the idea of implementing a small self-contained compiler for a small model language from scratch, not using other compiler construction frameworks. The course is built around an evolving family of languages with increasing expressiveness and complexity, which finally is crowned by a language with first-class functions, S-expressions, pattern matching, and garbage collection. The code generation technique is based on the idea of symbolic interpreters, which allows to implement a robust albeit not a very efficient native code generator. We give the motivation for the course, describe its structure, and report some results of teaching based on students' post-course surveys.
Intranasal Midazolam With Lidocaine for Sedation in Pediatric Myringotomy and Tube Surgery: A Randomized Controlled Trial

Background and Aims: Intranasal midazolam (INM) sedation for children has been associated with side effects. This prospective, double-blind, placebo-controlled trial assessed whether the addition of lidocaine to INM (INM+L) affected efficacy or discharge time among pediatric patients undergoing elective bilateral myringotomy and tube placement (BMT). Methods: This trial enrolled children aged between 18 months to seven years undergoing BMT, physical status class 1 or 2, in a single academic medical center. Interventions were placebo (intranasal saline), INM only (0.2mg/kg of INM concentration 5mg/ml), and INM+L (0.2mg/kg INM with addition of lidocaine 4% based on 25% of midazolam volume). Outcomes included post-anesthesia care unit times, observed behavioral distress (OBD) visual analog scale (VAS) (by nurse and parent), and sedation scores by certified registered nurse anesthetist (CRNA) and registered nurse (RN). Results: Forty-two subjects were included, 14 in each group, with 52% female, 41% physical status 2, and an average age of 2.7 years. Post-anesthesia care unit times averaged 36.5 minutes (range 15-132 minutes), with no delay in discharge with INM or INM+L versus placebo (p=0.88). Verbal complaints were highest among INM+L at the time of administration (p=0.01). RN-scored OBD at one minute post administration differed significantly across the three groups (p=0.01). Parental OBD scores did not differ across treatment groups. Agitation was greatest at time of induction of anesthesia in the placebo group (p=0.01). Conclusions: The addition of licodaine to INM does not adversely influence time to discharge and does not reduce side effects, improve efficacy, or change duration of action of INM.
The application of emerging new technologies by Portsmouth Dockyard 1790-1815

The history of the Royal Navy during the war with France between 1793 and 1815 is well documented, but the part played by new technologies in maintaining the Royal Navy as an efficient fighting force and contributing to its ultimate success is much less well recognised. This thesis addresses this problem beginning with an examination of the demands made upon Portsmouth Dockyard, the largest of the Royal Dockyards, due to the growth in the size of the fleet. It studies the nature of the tasks carried out in the Dockyard and the ways in which its personnel undertook them. Following a review of emerging new technologies and considering those which were, or were not potentially relevant to the Dockyard's activities, the thesis examines the technological advances actually applied in the period, how they were related to the site, to each other and to the workforce. The main innovations resulted in a major increase in the throughput of the dry docks, due to new dock design and the imaginative use of steam-power. In the metalworking area too, steam-power, together with other new technologies, provided major benefits to the Navy as a whole, especially in the reprocessing of copper. In the woodworking area revolutionary new blockmaking machinery was at the forefront of advances in efficiency and increased output of blocks for the rigging of ships. These advances were primarily due to a small group of men led by Samuel Bentham and Simon Goodrich, who became first "Engineer of the Navy". For their innovative use of new technologies and their management skills, these men can justifiably claim their place in the history of the Navy and of technology. More importantly, the applications of technology in Portsmouth Dockyard made a significant contribution to the industrial revolution in Britain during the period.
Particle Image Velocimetry in Concentrated Suspensions: Application to Local Rheometry

Abstract This paper presents an experimental facility that allows simultaneous viscosimetric and Particle Image Velocimetry measurements on concentrated suspensions in a wide-gap Couette rheometer. The experimental procedure is detailed: the optical characteristics of the index-matched suspension are carefully studied, the bottom end effect on both the viscosimetric measurements and the recorded velocity profiles are analysed. First the experimental procedure is tested on a Newtonian fluid whose viscosity is known. The spatial and time resolutions of our device are shown to be 200 mm and 100 ms. The precision of the local viscosity measurement is evaluated to better than 4 %. Then we show that the device can be used to characterize the rheological behaviour of a 47 %- concentrated suspension of 30 mm spheres. According to the particles large size, the Brownian motion can be neglected. However, colloidal interaction are still noticeable.
Safe placement of breakaway luminaire poles behind Midwest Guardrail System

ABSTRACT Luminaire poles are commonly installed along highways to provide proper illumination in critical areas. When placing light poles in close proximity to guardrail, the poles may affect the guardrail's ability to safely contain and redirect vehicles. The interaction between a deflected guardrail system and a closely-positioned light pole may create unwanted stiffening or hinging of the barrier system around the pole. The pole may also present a snag hazard to impacting vehicles and induce vehicle instabilities. In this study, the barrier clearance distance, i.e. the lateral offset away from a breakaway light pole was investigated and evaluated. The minimum safe lateral offset away from the pole with respect to the Midwest Guardrail System (MGS) was determined to be 508 mm (20 in.) through crash testing and computer simulation with non-linear finite-element analysis. Two full-scale crash tests were conducted according to the American Association of State Highway Transportation Officials (AASHTO) Manual for Assessing Safety Hardware (MASH) Test Level 3 (TL-3) impact safety criteria. In test no. ILT-1, a 2268-kg (5000-lb) pickup truck impacted the combination MGS with light pole system laterally offset 508 mm (20 in.) from back of posts at a speed of 100.7 km/h (62.6 mph) and an angle of 25.0°. In test no. ILT-1, the pickup truck was captured and safely redirected while impacting the light pole and disengaging the pole away from the base. In test no. ILT-2, a 1098-kg (2420-lb) small car impacted the combination MGS with light pole system laterally offset 508 mm (20 in.) from back of posts at a speed of 100.9 km/h (62.7 mph) and an angle of 25.6°. In test no. ILT-2, the car was safely contained and redirected while minimally contacting the light pole. The MGS with a lateral pole offset of 508 mm (20 in.) away from back of posts to front face of pole provided an acceptable safety performance to MASH TL-3 when critically impacted by a pickup truck and a small car. Thus, a minimum offset of 508 mm (20 in.) between the back of the MGS post and front face of the breakaway pole was sufficient to assure a safe performance of the MGS during vehicle impacts without undesired interaction with the pole. Accordingly, guidance for the safe pole placement behind the MGS was provided.

Engaging, Large-Scale Functional Programming Education in Physical and Virtual Space

Worldwide, computer science departments have experienced a dramatic increase in the number of student enrolments. Moreover, the ongoing COVID-19 pandemic requires institutions to radically replace the traditional way of on-site teaching, moving interaction from physical to virtual space. We report on our strategies and experience tackling these issues as part of a Haskell-based functional programming and verification course, accommodating over 2000 students in the course of two semesters. Among other things, we fostered engagement with weekly programming competitions and creative homework projects, workshops with industry partners, and collaborative pair-programming tutorials. To offer such an extensive programme to hundreds of students, we automated feedback for programming as well as inductive proof exercises. We explain and share our tools and exercises so that they can be reused by other educators. © K. Kappelmann, J. Rädle & L. Stevens.
The use of group drumming-based music therapy with male adolescents in a school violence prevention program in Korea: A pilot study

This study investigated how a drumming experience influences students’ aggression and narrative experience as related to school violence. Participants were 15- to 16-year-old students from two classes in a men’s high school in a Southeastern city in Korea. The students in one class (n = 38) participated in a group drumming-based music therapy school violence prevention program, while the 35 students in the other class participated in a didactic character education class. The Aggression Questionnaire (Korean Version) K-AQ was used for the quantitative data analysis, and individual semi-structured interviews with three participants, the classroom teacher, and researcher observations contributed qualitative data. A significant effect was found in the anger subscale of the K-AQ; no significant differences were found for the other 3 subscales (physical aggression, verbal aggression, and hostility). The qualitative data indicated that group drumming may enhance self-esteem, assertiveness, emotional expression, anger management skills, cooperation, feelings of unity, empathy, and active listening skills. These findings indicated that group drumming may contribute to reducing anger—one component of aggression—and may positively impact Korean male adolescents’ prosocial behaviors, as they pertain to school violence.
