This paper reviews the advantages and the current status of commercially available SiC power MOSFETs, followed by an analysis of future trends and the potential for future development. Specifically, the review shows the advantages of the recently commercialized trench MOSFET structure and the potential for integration with SiC Schottky diodes to create fast MOSFETs. The current issues and the potential...
This paper presents state of the art split drain current magnetic sensors fully compatible with the bulk silicon and SOI technology. While lateral double-diffused magnetic sensitive MOSFET with integrated n-type Hall plate exhibits an order of magnitude higher relative current magnetic sensitivity compering with the conventional split drain silicon MagFETs, novel dual-gate four-terminal magnetic sensor...
Conventional text-based information communications may cause misunderstanding particularly in case of a dialog between different generations, gender or cultural background. Intelligent communications may solve these problems by the aid of “happiness sensor” and retrieving additional information of personal record of the counterparts. Breakthroughs necessary to realize the intelligent communications...
Water droplets on the surface of silicon rubber were investigated under the influence of non-uniform electric fields. Several parameters of water droplets were investigated, such as the positioning of the droplets regarding the electrodes. The most striking conclusion is that the flashover voltage and electric field distribution depends on the positioning of the droplets from the electrodes.
In this paper an approach is developed for the online diagnosis of timed discrete events systems, the formalism used is the labeled timed Petri nets. We have introduced a new concept is: enriched set of possible states. In addition to online diagnosis our approach allows us to avoid the combinatorial explosion of states.
This paper considers a relayed broadcast in IEEE 802.11 wireless local area (WLAN) networks. In the relayed broadcast, a source node intends to deliver data frames to many nodes beyond its coverage and all the nodes except the source node attempt to relay the received data frames in a contention-based and distributed manner. This traffic dissemination scheme, referred to as flooding, has several problems...
We consider a full-duplex (FD) system where the uplink (UL) and downlink (DL) users are simultaneously served in the same bandwidth. We propose a new design that incorporates the power allocation for UL users and a joint beamforming and non-orthogonal multiple access for DL users under the effects of both residual self-interference and cochannel interference. In particular, a sum rate maximization...
In this paper the electrical and trapping characteristics of multilayer HfO2/Al2O3 dielectric stacks on silicon as a potential device for flash memory applications were investigated. Trapping phenomena have been studied by evaluating the memory window, i.e. the flat-band voltage shift of high frequency C-V curves after application of series of positive and negative voltages. The influence of post-deposition...
Safety instrumented systems (SIS) are designed to prevent the occurrence or mitigate the consequences of potentially hazardous events. The failure of SISs to achieve their assigned functions could result in huge consequences with respect to both (i) the safety of the monitored system (dangerous failures) as well as (ii) its production availability due to false trips (safe failures). The aim of this...
In this paper, we present a discussion on the congestion control for machine type communications (MTC) in long term evolution (LTE). A huge number of devices and the bursty nature of their packet arrival pattern are two important features of MTC and pose a challenge to the random access procedure of LTE. Access barring which consists of two types, access class barring (ACB) and extended access barring...
Metal-insulator-semiconductor capacitors used as a RC snubber attenuate voltage overshoots which may occur during switching phases. These devices feature good temperature stability up to 200°C and can be integrated very close to power switches on the same transfer substrate. As the capacitors need to withstand high voltages in most applications, thick dielectric layers have to be used, causing significant...
In this paper, we investigate the quality of information (QoI) maximization problem by jointly optimizing the sampling rate, packet-dropped rate, and transmit power in wireless sensor networks (WSNs). We consider a complicated but practical scenario, where various tasks with heterogeneous traffic are supported by one WSN simultaneously. Accordingly, the QoI maximization problem is formulated as a...
In this paper, the design of a multi-layer laminated busbar for a Si and SiC hybrid switch based 100 kW three-level T-type, single-phase, power electronics building block is presented. Due to the absence of three-level T-type topology in WBG based power modules at this power level, the PEBB design along with the busbar design is novel. This busbar facilitates the interconnection between the DC-link...
In the process of epidemic spreading, the most important question is: how a healthy individual does catch a disease? To answer this question, researchers have developed plenty models depending on the assumption that said the contamination factor is a β coefficient, which is defined probabilistically, representing the infection rate. However, in the real life, the contagion process could depend on...
The process where a laser and a Si waveguide were coupled was simulated by MATLAB. In order to obtain the coupling efficiency accurately and quickly, an improved finite-difference beam-propagation method(FD-BPM) and the simple transparent boundary condition(STBC) were selected. Several spot-size convertors (SSCs) of different structure with tapered Si waveguide, square SiON waveguide and SiO2 layer...
This paper presents a Cylindrical GAA TFET based on germanium source for low power applications. The proposed device used the merits of low band gap material such as germanium, which is used as a material in the source region. Device investigations have been made in terms of DC characteristics like ION, IOFF, SS, ION/IOFF. The proposed device increases ON-current as high as 1.9 × 10−5 A/μm, which...
This study concerns the problem of control for stochastic Markov jump systems with generally uncertain transition rates such that the system is finite-time dissipativity. First, sufficient conditions for finite-time boundedness is obtained by constructing Lyapunov function. Then, a state feedback controller is designed based on the results obtained. Finally, a numerical example is given to verify...
In this paper, we consider the output consensus problem of linear multi-agent systems subject to different agent dynamics by utilizing event-triggered control strategies. Both the dynamics and output of the agents are affected by non-identical disturbances, which are not measurable. The proposed event-triggered control scheme has a desirable feature that each individual agent independently decides...
With the increased global population, smart living is an increasingly important criteria to ensure equal opportunities for all. Therefore, what is Smart Living? The first time when we tossed this terminology seven years back, we thought reducing complexities in human life. Today we believe it more. However, smart living for all complicates the technological need further. As by all, we mean any age...
The recent market introduction of hydrogen fuel cell cars and the prospect of a hydrogen economy have drastically accelerated the need for safe and accurate detection of hydrogen. In the current work, in order to investigate the catalytic behavior of Pt/Pd bimetallic core-shell nanoparticles (NPs) for fast response hydrogen sensing; quantum size Pt/Pd core-shell NPs (3/3 nm) was deposited on the different...
