Residential gateways play a key role in providing internet access to home consumers. Nowadays, users in the same home with heterogeneous applications share a common gateway. As such, the gateway becomes the bandwidth bottleneck, leading to impairments and negatively affecting users' Quality of Experience (QoE). In the case of delay sensitive applications like video streaming and online gaming, this...
Cooperative intelligent transportation systems have become an active topic with the introduction of smart communications between vehicles, increasing driver safety, traffic efficiency and ultimately paving way for autonomous vehicles. These vehicular communications have stringent transmission requirements. Among various proposed communication protocols, use of heterogeneous networks, combining long...
When people decide on preferences of personal belongings, they consider not only the appearance of the object but also the its tactile texture. The design of tactile texture is an important factor in the development of commercial products. To measure a feeling of an object, a numerical evaluation method for tactile texture is required. The measurement is performed using a large-scale apparatus, generally...
To interact with humans in Human Social Environments (HSEs), robots are expected to possess the ability of situational context perception and behave appropriately. In this paper, we propose two deep learning models, as situational context perception of robot, to learn from observations of human-robot interaction. Based on these models, we endow robot the capability of perceiving human's mentation...
This article presents a substantial review of nonlinear memristive circuits based on Zdenek BIOLEK model alonside an innovator design developed within the Hewlett-Packard laboratories. HP realized a physical implementation of memristors by placing two layers of titanium dioxide between two electrodes.

Fault tree analysis (FTA) is a prominent reliability analysis method widely used in safety-critical industries. Computing minimal cut sets (MCSs), i.e., finding all the smallest combination of basic events that result in the top level event, plays a fundamental role in FTA. Classical methods have been proposed based on manipulation of boolean expressions of fault trees and Binary Decision Diagrams...
This paper describes the effect of MOSFET internal capacitances on the channel current during the turn-on switching transition: an intrinsic theoretical switching speed limit is found and detailed mathematically. The set of analytical equations is solved and the effect of the displacement currents is highlighted with ideal simulated waveforms. A laboratory experiment is thus performed, in order to...
This work proposes an Active Thermal Control (ATC) of power switches. Leveraging on the fact that thermal stress has wide impact on the system reliability, controlling thermal transients is supposed to lengthen the lifetime of electronic conversion systems. Indeed in some environments, such as transportation, reliability and lifetime are still obstacles to widespread adoption of electric and electronic...
With the aid of a storage-release mechanism named key-keysmith, an implementation approach based on chemical reaction networks (CRNs) for synchronous sequential logic is proposed. This design approach, which stores logic information in keysmith and releases it through key, primarily focuses on the underlying state transitions behind the required logic rather than the electronic circuit representation...
To solve the simulation convergence problem of Silicon Carbide metal-oxide semiconductor field effect transistor (SiC MOSFET) models, this paper proposes a non-segmented model for SiC MOSFETs, which uses non-segmented, smooth continuous equations to describe the static and dynamic characteristics of SiC MOSFET. Further, the static characteristic of SiC MOSFET obtained by the non-segmented model is...

Wide band gap power semiconductor devices are now replacing the Si-MOSFET or IGBT. GaN-HEMT achieves the reduction in size and weight, thanks to its high frequency switching behavior. However, its high-speed switching characteristics and low threshold voltage may cause a false turn-on phenomenon, which is a fatal effect for the applications. It is urgent issue to tackle and avoid this problem by modifying...

In this paper, we use Diagonal Recurrent Neural Networks on a sequence prediction task. The modification from standard RNN is simple: Diagonal recurrent matrices are used instead of full. This results in better test likelihood and faster convergence compared to regular full RNNs in most of our experiments. We show the benefits of using diagonal recurrent matrices with popularly used LSTM and GRU architectures...
