The purpose of this research is to evaluate the drain breakdown voltage of n-channel FD-SOI four-gate MOSFETs. Our approach is on the basis of three dimensional solution of Poisson's equation with proper boundary conditions for the surface potential and electrical field distribution. The model is extended to derive a model for the drain breakdown voltage which can predict the drain breakdown voltage...
Energy balance is a critical issue in wireless sensor networks. Several mixed data transmission (MDT) schemes have been proposed to achieve energy balance. However, most existing works are lack of theoretical study, especially understanding the relationship between network-wide energy balancing and lifetime optimization. In this paper, we conduct comprehensive theoretical analysis to the two-level...
FinFET is the dominating technology for short-channel devices due to its better gate control over the flow of electrons. In this work, the temperature dependence of drain current (ID) and short channel effects of Bulk FinFET is observed. The FinFET showed ID variation with respect to temperature. The drain current and short channel effects like subthreshold swing (SS), drain induced barrier lowering...
Modeling and controlling of warpages and layout-dependent local-deformations are challenges to overcome to realize 3D stacking of dies with through-silicon vias and micro-bumps. Dies larger than about 500 mm2 are now being used for high performance computing, and large cylindrical warpage of the die and local die surface deformations can greatly affect the yield and reliability of the stacked dies...
An electromagnetic field leaked from WPT systems might cause a false operation of other electronic devices. We have measured and simulated it by using the WPT leakage emulator so far. In this paper, the electromagnetic field is evaluated on the assumption that several WPT systems are located in the residential house and operate simultaneously. It is shown that the simulated results coincide with the...
Designing data channels for the DDR4 memory is a challenging due to high data rates of 3.2GB/s per data signal at a low-voltage of 1.2V The coupling of simultaneous switching noise (SSN) in data signals in DDR4 memory modules is a critical signal and power integrity (SI/PI) problem. It is important to catch SI and PI problems at an early stage in design that requires fast and accurate power-aware...
In this paper, we develop a comprehensive analytical framework to characterize the performance of device-centric content availability in device-to-device (D2D) networks. Modeling the locations of devices as a variant of Thomas cluster process, we derive the coverage probability of a typical device when its content of interest is available at its kth closest device within the same cluster. Using the...
Frame aggregation (FA) mechanisms improve the throughput of WLANs. In this paper, the effect of the FA mechanism on the throughput of wireless local area networks (WLANs) has been investigated. To this end, we propose an analytical model in order to analyze an IEEE 802.11n network comprised of an access point (AP) and several conventional nodes (CNs), all in the coverage area of each other. With respect...
In Long Term Evolution-Advanced (LTE-A) network, Machine Type Communications (MTC) allows machines to transfer data with almost no human intervention. In MTC, power saving is one of the most important issues. In the meantime, the 3rd Generation Partnership Project (3GPP) proposes Discontinuous Reception (DRX) mechanism to allow user equipments (UEs) to receive data only at specified time slots and...
Weapon systems selection is an unstructured, complex multi-criteria decision analysis problem with a wide range of considerations. In this paper, a hybrid approach which uses VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) technique, is presented for the screening of weapon systems. More specifically, a group of experts are first asked to make judgments on the criteria using...

In this paper, the text semantic orientation analysis method is proposed based on Hidden Markov Model to improve the accuracy...
This paper presents a 2D analytical model for symmetric double gate Tunnel Field Effect transistor (DG-TFET) based on tunneling path in the channel. The potential profile is obtained by solving 2D Poisson's equation in the rectangular coordinate system. The drain current is extracted by integrating the band to band tunneling generation rate, initial and final tunneling length. The primary focus is...
In enterprises, timed compatibility (i. e., temporal constraint satisfiability) have become an important factor to guarantee the timely completion of service composition so that meet the requirements of customers and ensure the success execution of enterprises. However, existing researches do not fully investigate the mixture situations where distributions of service durations are complex and diverse,...
New system development may not require designing all components; existing components can be used. Although the reliability of each component may be available, it is still difficult to accurately predict the system reliability in the early design stage. The system designers may not access all details of component design to consider components dependencies. This work attempts to explore the feasibility...
The price fluctuation in the stock market is often accompanied by risks, the spread of which affects the entire financial system and even the stable operation of the social economy as a whole. Considering the relatively mature research for the network characteristics of the stock market, this paper attempts to employ the complex networks analysis method to study the risk of the stock market. We firstly...
In this paper, we present precise time and energy models for an intra-only HEVC video encoder. These models are a step forward to understand and estimate the computational complexity and energy demands of an HEVC encoder, which in turn opens the path to finely tuning the computational resources that are dedicated to this purpose. Our models estimate the complexity and energy consumed by the HEVC encoder,...
The electrical characteristics of Through Silicon Via (TSV) have been frequently studied recently, but most studies focused on the single-ended TSV structure. Specially, study about the differential TSV structure is rather limited. In this study, three-dimensional electromagnetic simulation software HFSS was used to analyze the transmission characteristics of the differential signal of the differential...
In this paper we propose a general class of models for spreading processes we call the SI*V * model. Unlike many works that consider a fixed number of compartmental states, we allow an arbitrary number of states on arbitrary graphs with heterogeneous parameters for all nodes and edges. As a result, this generalizes an extremely large number of models studied in the literature including the MSEIV,...
Cost remains a key factor for implementation of Through Silicon Via (TSV) in high-volume manufacturing. As compared to via-first and via-middle TSV, via-last (from wafer back-side) TSV possesses the advantage of a more simple process flow and more flexibility in integration for more varied applications. Previously, a cost model analysis for Through-Silicon-Interposer (TSI) using via-first TSV has...
