Supplying electrical energy to the load on demand, economically and with acceptable levels of reliability and service quality is the main task of a distribution system. Energy distribution reliability is important in the competition conditions in electricity markets because consumers directly supply energy. Therefore, it is not enough to estimate how reliable the distribution system is at present...
Drop test for solder joint reliability is critical for all area arrays and perimeter-leaded surface mount semiconductor devices typically used in handheld electronic products. Joint Electron Device Engineering Council, JEDEC, published a new test standard, JESD22-B111A, to be the revision of the JESD22-B111 for board level drop test in November, 2016. The major differences between JESD22-B111 and...
This paper proposes an algorithm that uses predefined weights to create broadcast routes for a WirelessHART network. The network topology is represented by a graph, and the algorithm uses information of the devices present in the network to build the broadcast graph. At each iteration of the algorithm, a device is selected and then added to the broadcast solution graph. A cost function determines...
We present a digital system for measurement of neutron spectra in mixed gamma-neutron fields. The signal from a standard scintillation detector is sampled at rate up to 1 GHz, using 12-bit analog-to-digital converters. First stage of the signal processing is performed on a Virtex 6 FPGA and partial results are streamed through a fast Ethernet link to a computer, where the final processing takes place...
DC-link capacitor is one of the reliability-critical components in motor drive applications, which contributes to a considerable cost, size and failure. Its reliability performance depends on both inherent physical strength and external loading. The grid unbalances could alter the electro-thermal stresses of key components in a motor drive. Therefore, this paper investigates the impact of grid voltage...
The standard and real-time communication technology is an unalloyed inevitability for the development of Internet of Things (IoT) applications. However, the selection of a standard and effective messaging protocol is a challenging and daunting task for any organisation because it depends on the nature of the IoT system and its messaging requirements. Copious messaging protocols have been developed...
Integrating engineering into K-12 classrooms is gaining considerable attention. With new standards, such as the Next Generation Science Standards (NGSS), that require the incorporation of engineering through design into the K-12 curriculum, it is essential that opportunities be provided to those teaching in K-12 to aid in appropriate integration. Translating Engineering Research to K-8 (TEK8) addresses...
SF6 Gas-Insulated Metal-Enclosed Transmission Line (GIL) has the advantages of large transmitting capacity, low loss, small electromagnetic pollution for surroundings, strong capability to resist geological disasters, easy operation and maintenance, etc. In-depth research on the key technology of UHV GIL insulating part design, flexible line design, line manufacturing and detection, GIL installing...
The goal of this paper is to provide a forum to discuss design activity from two different perspectives: industrial design and electrical engineering. We start with a general overview of design activity as defined by Larson and Dorst[1]. Next, perspectives on design are presented by two of the paper's authors, specifically in the following areas: identifying and framing design problems, design representations,...
This paper proposes a reliable MAC protocol for a fully distributed Vehicular Ad-Hoc Network (VANET) using the slot states sharing scheme. Recently, technology for reliably transmitting safety messages in VANET has become an issue. With VANET (operating on the IEEE 802.11p standard), as the number of vehicles increases on the highway, the network traffic also increases. It causes more frequent packet...
In this paper, we propose a systematic design approach of polar codes for multicolor visible light communication (VLC). Owing to the mixed ratio of multicolor light intensities and the interference between different colors, the channel polarization over a multicolor VLC system is markedly different from that over a uniform channel. Our scheme quantifies these different color channels and constructs...
The number of users and amount of data transfer are increasing per each minute with the rapid growth of social network platforms on the web while the users have no certain knowledge of each other. Thus, with the overwhelming spread of the internet and such bulk of data, people find it arduous to identify valid comments. Establishing a genuine and more accurate trust becomes harder if classical processing...
The complexity of the mechanism brings great difficulty to the calculation of the mechanism motion reliability, and the computer simulation algorithm based on Monte Carlo method needs a great number of simulation. The further-development of LMS Virtual. Lab was carried out, and the least square support vector machine algorithm was used to construct the response surface proxy model. The PSO-GA algorithm...
The application of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements to crystals and crystal elements as well as the need for certification of these products. The use of single crystals in acousto-, opto-, micro — and nanoelectronics defines strict requirements both to crystals and crystal elements, and it concurrently defines the need for the certification...
Internet of Things (IoT) has become a favored wireless communication concept in many application domains recently. Most of the IoT networks must fulfill the strict quality of service (QoS) requirements such as low latency and high reliability. Besides, low power consumption is essential in those networks due to the use of battery operated devices. Time Slotted Channel Hopping (TSCH), an operating...
Industrial applications demand for ease of deployment, reliability and low-power in wireless networks, leading to standards like IEEE802.15.4, which include time synchronized channel hopping mechanisms. Yet, scheduling of transmissions on timeslots and channels falls outside the scope of current standards. Given the application requirements above, distributed (rather than centralized) scheduling has...
Vehicular Ad Hoc Networks (VANET) have become one of the most important research areas for the successful and deployment of intelligent transportation system and the unmanned vehicle technologies. In VANET, Travel Prediction-based Data Forwarding (TPD) was proposed as one of novel data forwarding schemes based on road traffic statistics. However, the TPD could not guarantee good performance in the...
In modern industrial control, it is significant to achieve interoperability of state data and control data at field level and service management layer. Therefore, the demand for data exchange and sharing is getting higher and higher. This paper presents a research of the common mainstream network protocols on industrial network architecture of Northbound Interface, then it makes a comprehensive analysis...
Augmenting educational opportunities for rural village girls in India has been highlighted as a significant Millennium Development Goal (MDG) necessary to help eradicate poverty in developing countries. The role of proper electrification in rural villages, another MDG, plays a significant role in providing necessary energy for educational needs. In a small village in the state of Jharkhand, India...
