This work considers message coding on a transport layer of data network using error correcting codes. Initially transport coding was presented with constant coding rate [1]. This work suggests usage of variable coding rate by recoding messages on some intermediate nodes of data network. The work contains analysis of recoding efficiency based on analytical model and simulation of Kleinrock network...
Analytical models of stress and deformxation of through-silicon vias (TSV), relative to numerical ones, have the advantage of being inexpensive to evaluate and in providing insight. They have the additional advantage of allowing one to embed them in ECAD tools for real time design decisions. Motivated by this reasoning, in this paper, an analytical model for the three-dimensional state of stress in...

Cloud computing and service computing can be integrated into a distributed computing platform which provides a set of services to their users. Different services could cooperate with each other to accomplish more intricate tasks. However, third-party cloud services may cause failures or quality violation of workflow applications. Especially in some critical business scenarios, service performance...
In this paper, we present the analysis of the new transmission algorithm of RFID in form of multichannel which has been developed from frame slotted ALOHA protocol. By using concept of the tag transmission group division which differ in slot access ability and the multinomial distribution foundation for calculate each probability of successful transmission slots. And compare with the ordinary frame...
In different kinds of surface-based chemical and biological micro/nanosensors, interpretation of the experimentally obtained data is performed based on approximate solutions for the sensor response, valid for the case of single-analyte samples. A question arises whether or not the approximate models used for experimental data fitting in the case of a single analyte are also applicable for multianalyte...

The analysis results in IT Value Model using Variance-Based Structural Equation Modeling. Using computer simulation...
Recently, the use of permanent magnet (PM) motors has expanded remarkably as a result of improvements in the performance of the rare-earth PM motor. However, it is desirable to reduce the use of rare-earth materials, which are an important aspect of the high-performance PM motor, because of the high cost and the unpredictability involved in procuring such materials. The performance of motors that...

On the basis of group theory and the environment-based modeling of group robots, the kinetic equation of self-reconfigurable robots is established. Comparing...
In this paper, the performance analysis of the model of gradient neural network (or termed G-type model), which was designed originally for solving constant linear equation, is investigated, analyzed and simulated for online solution of Zhang linear equation (ZLE or termed time-varying linear equation). Compared with the constant case, G-type model for online ZLE solving can only approximately approach...
This paper present an analytical model of delay for subthreshold voltage to time converters (VTCs). The model characterizes an equation between the input voltage and output delay. Delay prediction model can be used to compute delay and understand characteristic of VTC in subthreshold region. Simulations are done in 0.18um CMOS technology and results ensure the accuracy of the model.
The T-match is a frequently cited impedance matching technique for UHF RFID tags. However, there appear to be many misconceptions about what the term “T-match” actually implies and when the relevant assumptions no longer apply. This work focuses on creating a clear definition of the T-match design space in order to differentiate it from other impedance matching techniques. A comparison between analytic...
Numerical analysis and analog simulation are used to investigate the FSI (fluid structure interaction) characteristics of a differential pressure flow sensor. The FSI model is created using the hydromechanics and elastic mechanics, and a systematic theory is created to finish the numerical analysis. Then the working mechanism of the flow sensor is analyzed depend on the FSI results. The commercial...
The heterogeneous integration between CMOS devices and different emerging nanotechnologies such as the single-electronics tries to take the best of each technology. On one hand, the advantages of MOSFET devices are high speed and high current and the relative maturity of fabrication technology. On other hand, single-electronic technologies have the potencial to create high-density devices and have...
The conventional mathematic model of PV (Photovoltaic) cells contains logarithmic terms, which is not conducive to derivation calculation in small-signal modeling. The parameters of PV system are coupling due to its double-loop control method, and it's hard to precisely choose controller parameters. To solve these two problems above, this paper is based on PV system connected to an infinite power...
The computation of a peeling order in a randomly generated hypergraph is the most time-consuming step in a number of constructions, such as perfect hashing schemes, random r-SAT solvers, error-correcting codes, and approximate set encodings. While there exists a straightforward linear-time algorithm, its poor I/O performance makes it impractical for hypergraphs whose size exceeds the available internal...

Analyzing worst-case application timing for systems with shared resources is difficult, especially when non-monotonic arbitration policies like First-Come-First-Served (FCFS) scheduling are used in combination with varying task execution times. Analysis methods that conservatively analyze these systems are often based on state-space exploration, which is not scalable due to its inherent susceptibility...
