Transformation of Type I Fuzzy Logic into Interval Type II Fuzzy Logic-based Unit Voltage Template with Controlled Load

The interval type II fuzzy logic controller (IT2FL) is a recent artificial intelligent technology which is applied in many aspects of electrical power engineering and controlling strategies these days. The improving of Distribution Static Synchronous Compensator (DSTATCOM) control algorithms is still ongoing, because the control strategy of DSTATCOM device is considered as a decisive factor which affects the performance of DSTATCOM device in enhancing the quality of power in the distribution grids. The improving process focuses in two main aspects the DC capacitor voltage response to the control system and the mitigation of the harmonics which are produced by the controlled and uncontrolled rectified loads. In this paper, the interval type II fuzzy logic controller (IT2FL) based the Unit Voltage Template strategy (UVT) is examined by the MATLAB program with two different ranges of input signals, and compared with the type I Fuzzy logic controller (T1FL). The IT2FL based UVT shows promising results in improving the deformed shape of source current waves in comparison with the other controllers.

Unlocking the full potential of monolithic perovskite/biPoly™ Si tandem devices through in-depth analysis and detailed engineering

Perovskite/Si tandem solar cells have emerged as one highly promising tandem configuration of tandem devices for 1-Sun photovoltaic systems. Up to now, heterojunction (HJ) cells have been the dominant silicon bottom cell structure and holds the record efficiency of dual-junction perovskite/Si tandem cells, whereas the investigation on perovskite/Si tandem cells using Si bottom cells that dominate today's mass markets (such as PERC and TOPCon) is still limited. In this work, we delve into the crucial optical and electrical engineering aspects required for perovskite/Si devices based on bifacial TOPCon structures (biPoly™), which has high efficiency potential as a single-junction Si cell, enables TCO-free contacts and is expected to be compatible with current mass production technologies. Simulations predict that such devices can potentially achieve a current density of 20.4 mA/cm2 despite of the parasitic absorption in poly-Si layers, comparable to that of HJ-based perovskite-Si tandem devices. We also demonstrate through simulations that edge and peripheral recombination effects can be mitigated by selecting an appropriate substrate size and employing locally doped poly-Si layers. Such improvements are also preliminarily verified with a prototype device. By carefully designing device structures and advancing fabrication techniques, perovskite/biPoly™ Si tandem cells can come closer to realizing the full potential of biPoly™ cells and achieve efficiencies comparable to those observed in devices utilizing HJ cells.

Research on Building Electrical Design Based on Computer-Aided

Computer aided electrical design (hereinafter referred to as electrical CAD) refers to the application of computer aided design in the design of electrical parts in many industries. Electrical CAD application includes all aspects of electrical engineering. The application of computer in electrical design system is very important and extensive. After the computer is put into use in circuit design, relay protection design and auxiliary management, it has played a certain role in promoting the operation and development of the whole electrical industry. Computer software should be tailored to the needs of different customers. It is necessary to gradually subdivide the development of the user market and expand the new direction of the market, and continuously develop more targeted and professional building electrical computer aided software to meet the needs of production and design. In this paper, the application of computer aided in building electrical is discussed and studied in detail[1].

A flexible robotics themed system for teaching basic engineering concepts and skills

The robotics stream of the University of TorontoDEEP summer program consistently attracts numer-ous motivated high school students. As instructors,we have developed an extensible low cost platformthat students can construct and enhance over asequence of courses. The platform provides anengaging medium to address many aspects of elec-trical, computer and mechanical engineering whilemaintaining a robotics theme. These include thetheory of electromagnetism, analog and digitalcircuits, software development and ultimately basicmachine learning. Students surveys conducted at thebeginning and end of each course were used to gaugestudent engagement and knowledge before and afterthe courses and provide evidence that the roboticsthemed approach is an eective method for teachinga broad spectrum of engineering material.

Electrical methods of controlling bacterial adhesion and biofilm on device surfaces

This review will summarize the significant body of research within the field of electrical methods of controlling the growth of microorganisms. We examine the progress from early work using current to kill bacteria in static fluids to more realistic treatment scenarios such as flow-through systems designed to imitate the human urinary tract. Additionally, the electrical enhancement of biocide and antibiotic efficacy will be examined alongside recent innovations including the biological applications of acoustic energy systems to prevent bacterial surface adherence. Particular attention will be paid to the electrical engineering aspects of previous work, such as electrode composition, quantitative electrical parameters and the conductive medium used. Scrutiny of published systems from an electrical engineering perspective will help to facilitate improved understanding of the methods, devices and mechanisms that have been effective in controlling bacteria, as well as providing insights and strategies to improve the performance of such systems and develop the next generation of antimicrobial bioelectric materials.

Designing and Building a Battery-Powered Car

Designing and Building a Battery-Powered Car For many years now Electrical Engineering students at the US Naval Academy have been involved in renewal energy types of projects, including electric boats and cars, and have participated in various competitions across the US. Of particular interest to us is the electric car, since it involves various aspects of electrical engineering. As part of their senior capstone project, and under our guidance and supervision, four students designed, built, and tested the power generation and distribution system, the motor control system for an electric car. This was accomplished by converting an originally gas-powered car into a battery-powered car, whereby solar panels are used to recharge the batteries. Towards this end, a mix of off the shelf parts and components, and homebuilt circuits were used. The design considerations include selecting an appropriate control system, choosing suitable batteries, utilizing solar panels to recharge the batteries, designing the lighting system for the vehicle, and implementing several key safety features, including an emergency shut-off switch.

Precision engineering for wind energy systems

The production, installation and operation of wind energy systems (WES) has gained a significant importance in the past two decades, forming a new and world wide rapidly growing industrial branch. Moreover, WES technology contributes a safe and substantial share (about 20% by 2020) to the electrical energy supply of many countries. It thus enables them to achieve their environmental and sustainability objectives. Contrasting to this prospering development, WES industry faces some major challenges. Among these are the reliability, lifetime and costs of WES, namely offshore WES. This paper will be focused on the design, manufacturing and accuracy of decisive mechanical components like the wind rotor system and the drive train (including bearings and gears), whereas economical, environmental, civil and electrical engineering aspects are only mentioned in passing.

Educating and Training Accelerator Scientists and Technologists for Tomorrow

Accelerator science and technology is inherently an integrative discipline that combines aspects of physics, computational science, electrical and mechanical engineering. As few universities offer full academic programs, the education of accelerator physicists and engineers for the future has primarily relied on a combination of on-the-job training supplemented with intensive courses at regional accelerator schools. This article describes the approaches being used to satisfy the educational curiosity of a growing number of interested physicists and engineers.

새로운 학부 의공학 교육과정의 일환으로 의공학 실험과목의 제안

Laboratory class is an integral part of biomedical engineering education. Current biomedical engineering curriculum in Korea mostly includes mandatory laboratory classes. Most of the Korean biomedical laboratory classes focus on electrical engineering aspects, while molecular/biological engineering aspects are neglected. Many leading universities in U.S.A. offer a more balanced laboratory class where both electrical engineering aspects and molecular/biological engineering aspects are considered. As a part of an effort to enhance undergraduate biomedical engineering education, a new biomedical engineering laboratory class is proposed to offer a more balanced laboratory learning experience.

Engaging Robots: Innovative Outreach for Attracting Cybernetics Students

Cybernetics is a broad subject, encompassing many aspects of electrical, electronic, and computer engineering, which suffers from a lack of understanding on the part of potential applicants and teachers when recruiting students. However, once the engineering values, fascinating science, and pathways to rewarding, diverse careers are communicated, appropriate students can be very interested in enrolling. At the University of Reading, Reading, U.K., a key route for outreach to prospective students has been achieved through the use of robots in interactive talks at schools, competitions (often funded by Public Understanding of Science projects), a collectable fortnightly magazine, exhibitions in museums, open days at the University, and appearances in the media. This paper identifies the interactive engagement, anthropomorphic acceptability, and inspirational nature of robots as being key to their successful use in outreach activities. The statistical results presented show that the continued popularity of degrees at Reading in cybernetics, electronic engineering, and robotics over the last 20 years is in part due to the outreach activities to schools and the general public.

Preface to the focus theme section: ‘Internet of things’

“Ubiquitous Computing” (Weiser 1991, 1993), “Pervasive Computing” (Satyanarayanan 2001; Estrin et al. 2002), “Things that think” (Gershenfeld 1999), “Ambient Intelligence” (Aarts et al. 2002), “Silent Commerce” (Ferguson 2002)—a plethora of novel terms has evolved in recent years that propagate the coming of a new paradigm shift in information processing. Common to all these concepts is the shared vision of a future world of everyday physical objects equipped with digital logic, sensors, and networking capabilities, which together form a so-called “Internet of Things” (IoT). Whereas computing power was a scarce resource in the former times of mainframe computers and PC’s, the IoT bears the promise of omnipresent real-time access to information and services centred around arbitrary objects and users with their individual tasks and objectives. It is neither a single technology nor a specific functionality which is behind the IoT but rather a bundle of functions implemented by a diverse set of systems and technologies. IoT-related research is accordingly characterised by a multidisciplinary approach that includes aspects of electrical engineering, computer science, management research, psychology and many more (Satyanarayanan 2001). For this reason, the following list of an object’s technological capabilities in the IoT can be regarded as typical but does not claim completeness:

Areas of Electrical and Computer Engineering Education That Require Increased Emphasis

Two important aspects of electrical and computer engineering (ECE) education that require increased emphasis are discussed: instruction on the topic of transmission lines, and improving the mathematical skills of ECE students. Reasons for the need for a renewed emphasis on these two fundamental areas, as well as methods for incorporating them into an already crowded undergraduate ECE program are addressed.

Mechanical and electrical engineering aspects of long-distance underground power transmission

The delivery of the power from remote power generation sites to urban centres is increasingly becoming a challenge for the power industry since the use of traditional power transmission technology, such as overhead cables, is a politically sensitive issue and alternative approaches are sought. This paper reports the findings of a feasibility study into long distance power transmission via small diameter underground tunnels, constructed using trenchless technologies such as horizontal directional drilling or microtunnelling. The study examines the suitability of AC or DC transmission for such underground tunnels, various cooling methods to remove the heat generated in the conductors from electrical losses, type of conductor to be used, and issues concerning conductor installation. As a result of this study a number of technical challenges have been identified that need to be overcome in order to make the method an economically and technically viable option.

An Australian Hydroelectric Milestone - the 1895 Duck Reach Power Scheme

AbtractThe Duck Reach hydroelectric scheme on Tasmania's South Esk River commenced operation in December 1895, making it the first truly successful, substantive scale hydroelectric scheme built for public electricity supply in Australasia, and one of the early municipal hydroelectric schemes on a world scale. The scheme served the City of Launceston for 60 years until it was superseded by the Hydroelectric Commission's larger Trevallyn hydroelectric development in 1955. This paper reviews the history of the Duck Reach scheme, its rapid public acceptance and early expansion to meet an ever increasing demand for electricity supply. It also looks at the associated electricity distribution in the City of Launceston that began with series DC circuits for arc lights in the major streets, and single-phase AC for suburban street lighting and private consumers. Within 10 years the scheme converted to three-phase AC, with four-wire, MEN-connected, low-voltage distribution, reportedly making Launceston one of the first cities in the British Commonwealth to adopt the latter system. The paper is based primarily upon the study of earlier written records, particularly the seminal early papers by the scheme's original design engineers and the first City Electrical Engineer. While the important civil and hydraulic engineering elements are described, more detail is devoted to the electrical engineering aspects.

Teaching professional and ethical aspects of electrical engineering to a large class

As electrical engineering has expanded and diversified with the technology it creates, it has also more firmly established itself as a well-respected profession that has provided significant benefits to society. Electrical engineering education is continually diversifying to keep step with the profession. For instance, the area of professional and ethical aspects of electrical engineering is increasingly found in electrical engineering programs, either as a stand-alone course or as a topic discussed in conjunction with design (courses). Most view this as a positive development since it is often thought that the focus on professionalism and ethics is likely to help maintain the integrity and respect of the profession as a whole. In this paper we identify resource materials, background information, a syllabus, and outline for teaching a course on professional and ethical aspects of electrical engineering. Special attention is given to issues encountered when this topic is taught to a large class. In particular, it is explained how to turn the large class problem into an advantage that can actually enrich the educational process of teaching professional and ethical aspects of electrical engineering.

A new graduate program in acoustics

The University of Massachusetts Dartmouth is offering a new graduate program in the area of Marine Acoustics leading to the degree of Masters of Science in Electrical Engineering with a specialization in Marine Acoustics. The Marine Acoustics specialization is multidisciplinary in nature bringing together the physical, mechanical, and electrical engineering aspects of the study of the production, propagation, and reception of underwater sound. The graduate program is currently running on campus as well as off-site at the Naval Undersea Warfare Center (NUWC) in Newport for as many as 60 students. Students in the NUWC program have completed the first 4 courses of an 11-course program consisting of a Mathematics Review (ECE403), the Fundamentals of Acoustics (ECE 557), Random Signals (ECE 521), Underwater Acoustics I (ECE 597), Underwater Acoustics II (ECE 597), Acoustic Transduction (ECE699), Digital Signal Processing (ECE574), Sonar Signal Processing (ECE575), Sonar Systems Engineering (ECE675), and a graduate thesis or two additional graduate courses (e.g., Computer Systems, Nonlinear Acoustics, etc.). The program is expected to provide the student with a good foundation in acoustics. Details will be elaborated on during the presentation. [Program sponsored by NUWC and UMass Dartmouth.]
