A model of copper and carbon nanotube (CNT) composite filled through silicon via (TSV) is developed to estimate signal delay of a novel interconnect, employed in 3D integrated circuit (IC) design. The main objective of 3D interconnect is to electrically connect two stacks of circuits and offer robust chip functionalities. The 3D integration scheme allows independent design of operational blocks in...
The objective of this study is to analyze delay at signalized intersections using micro simulation approach. Traffic signal delay is one of the major problem people face in urban areas. An effective traffic signal timing and phasing arrangement has to be implemented to optimize the delay for all vehicle moments through the junction. Apart from signal timing arrangement, other factors such as geometry...
This paper presents a new insight into the stability of discrete-time systems with time-varying delays. New stability criteria are obtained in terms of linear matrix inequalities. The novelties of the paper come from two aspects. First, this newly presented criterion does not require all the symmetric matrices involved in the employed quadratic Lyapnov-Krasovskii functional to be positive definite...
In this paper, we will develop pth moment stability criteria for stochastic delay differential equation with Markovian switching. A new sufficient condition is derived to guarantee the pth moment stability by matrix inequality technique and Lyapunov-Krasovskii functional. The result extend the Theorem 7.23 in Mao [1].
In this paper, we present experimental results on WebRTC voice quality as a function of LTE radio coverage. Different LTE radio conditions were tested by varying the radio path loss (with fast fading) in controlled test lab conditions. Voice quality was evaluated at different speech coding bit rates in terms of POLQA score and mouth-to-ear delay. Results show that, with acknowledged mode (AM) data...
We present a new trajectory based approach for state feedback stabilization of switched linear continuous-time systems with a time-varying input delay. In contrast with finding classical common Lyapunov function or multiple Lyapunov functions for establishing the stability of the closed-loop switched system, the new trajectory based approach relies on verifying certain inequalities along the solution...
In this paper, a robust decentralized feedback control is proposed for large scale networked control systems. Some less conservative sufficient conditions are presented for existence of the robust decentralized feedback controller for large scale networked control system under digital communication to have maximum robustness against admissible time delays, consecutive packet loss, disturbances and...
The problem of variable structure guaranteed cost control for discrete uncertain networked systems with time delay has been considered in this paper. Based on the Lyapunov stability theorem, by introducing a discrete compensator, a novel sliding mode manifold that can compensate time delay has been designed. Then, by using linear matrix inequalities approach, a guaranteed cost controller is designed...
We study a mathematical model of cohabitation of healthy and unhealthy stem cells, in order to address some new biological concerns. In short, we will investigate the existence and the stability properties of a positive steady state of a model that is well adapted to the study of dormancy of cancer stem cells. Mathematically, we are concerned with the analysis of a nonlinear retarded system coupled...
Through Silicon VIAs (TSVs) are critical elements in three dimensional integrated circuits (3D ICs). Various defects may occur during their fabrication process, the bonding stage or during their useful lifetime. In this work a testing method is suggested to detect the defects using a post-bond oscillation test scheme. Variations in the output signal's frequency are shown to detect the defects in TSVs...
While 3D integrated circuits provide many security advantages, one disadvantage is the insertion of a Trojan die into the stack. In this paper, we explore a technique to detect an extra die through delay analysis.
The Service-Oriented Software Development (SOSD) approach is a common software development paradigm. Previous qualitative and quantitative studies looked at the main reasons for the delay in software development so as to help project's stakeholders to take appropriate actions for improvement in their planning. In SOSD projects, due to the high level of user involvement in new service and product development,...
The factors which play a pivotal role in VLSI system design are power, delay and area. In order to carry out fast arithmetic functions in many data processing processors, Carry Select Adders (CSLAs) are widely used because they are one amongst many of the fast adders that could be used for the high speed data processing. CSLAs stand out from the remaining conventional adders in terms of performing...
The recent trends in deploying multimedia systems, such as education, telemedicine, military and space endeavors is to deliver a smooth and uninterruptable video along with audio is a challenging task nowadays. The operators started using standard servers in the cloud. The internet based computing which provides more on-demand computing resources over the internet. Video Transcoding the method adapted...
The main requirement of Very Large Scale Integration (VLSI) circuit is to be fast and low energy consumption. So, the analysis is done by optimizing the delay, which results in fast processing and low average energy consumed. A 3 transistor XNOR gate is proposed. The proposed XNOR gate is designed using CADENCE EDA tool and simulated using the SPECTRE VIRTUOSO at 90 nm technology. The results from...
In this paper, we introduce a new extension of Time Petri Net (TPN) to specify complex synchronization schemes in concurrent and parallel systems. Synchronizations are defined by a new mechanism called, rendezvous. The latter allows to a set of transitions to fire synchronously according to a synchronisation scheme induced by four delay parameters and two localities. The TPN extended to rendezvous...
Analysis of Network Intermediate Connectivity is one of the important and challenging issues in Vehicular Adhoc Network (VANET). Gradually, intermediate connectivity among the nodes becomes a popular interesting research paradigm in high mobility domain. It depends upon the movement pattern of the vehicles and the routing of packet transmission depends upon the connectivity of the nodes. Among the...
For minimizing road accidents, traffic jams, car parking and other significant scenarios related to cost effectiveness and safety in VANET, the communication between vehicle to vehicle and vehicle to road side unit (RSU) should achieve the service quality, high data receive ratio and low latency. However, the probability of TCP disruption increases by the increasing distance between source and destination...
Inventions in electronics and communication industries increased rapidly the utilization of wireless sensor networks, still the selection of the routing algorithm is done application wise. The existing routing protocols are having many problems and limitations in terms of Quality of Service parameters, like energy consumption is more, delay and jitter are high, throughput and packet delivery ratio...
