In this paper we investigate the performance of linear interactive encoding and decoding based on syndrome accumulation(SA-IED) over binary LDPC ensembles. Assume that the source alphabet is GF(2), and the side information alphabet is finite. It is shown that we can construct universal SA-IED schemes, which are asymptotically optimal for any stationary ergodic source-side information pair. Our analysis...
Copulas are functions that join or couple multivariate distribution functions to their one dimensional marginal distribution functions. Alternatively, copulas are multivariate distribution functions whose one-dimensional margins are uniform on the interval (0,1). The appeal of copula function lies in the fact that it eliminates the implied reliance on the multivariate normal or the assumption that...
The ballistic conductance of a device consisting of two quantum point contacts, separated by a distance smaller than the spin coherence length, has been measured at 4.2K. A conductance plateau at 0.5 (2e2/h) is observed in the absence of external magnetic field indicating spontaneous spin polarization. This happens when the confining potentials of the point contacts are made sufficiently asymmetric...
This paper proposes a multi-agent model for the studying of the self-organization teampsilas behavior. The model is dependent on the interaction rules and the decision factors of team members. Three kinds of team members (reciprocators, cooperators and selfish) are proposed in the paper. The team members work with one of three work attitudes (diligence, average, shirking). A small-world network is...
In todaypsilas life, the importance of accessing data and information from Internet and other networks for business, entertainment, and social activity applications is ever increasing. Network protocols such as Wi-Fi (802.11) and WiMAX (802.16) have been developed for such applications. However the need for a high-speed, highly reliable and high quality access to these information services under fully...
With the development of wireless and mobile Internet technology, people in everyday life and business hope for access to the Internet even while they are in movement. IEEE 802.20 technology is mobile and can effectively address high-speed network access. In this paper the PHY layer model for simulating 802.20 in SIMULINK and subsystems in MATLAB S-function files are presented. To evaluate the performance...
Urban public traffic is an important basic infrastructure related to the nationpsilas economy and the peoplepsilas livelihood, which is social cause of public good closely linked people's production and life. In order to evaluate the urban public traffic satisfaction scientifically, based on the analysis of the urban public traffic present and problems, this paper establishes a satisfaction evaluation...
The modeling and simulation of container terminal logistics system is rapidly developed and widely applied. This paper describes three parts of the modeling and simulation of container terminal logistics system, which includes Logistics system modeling technology, Verification Validation and Accreditation and screening test, and then the research approach and target, the primary coverage and the key...
According to the different branches of citypsilas intersections and the traffic flow at different times, the program of intelligent traffic light controller based on VHDL is given and simulated by Quartus II by using hierarchical design thought. The simulation results show that the intelligent traffic light controller can realize the transition of 2-phase, 3-phase and 4-phase based on actual situations...
Data communication is deeply studied to solve the real-time property and the stability of the data communication that is the key problem in the battle damage simulation system, following the logic process of data generating, sending, transmitting, receiving. Meanwhile, a series of optimized methods are proposed from the aspects of communication interface, communication server working model, concurrent...
In this paper, we study the shared path protection (SPP) problem in wavelength division multiplexing (WDM) optical networks, and propose a novel SPP algorithm with differentiated reliability (DiR) called SPP-DiR. Differing from previous work, SPP-DiR algorithm effectively adapts to the diversity demands of customer requests and has higher resource utilization than SPP algorithm. Therefore, SPP-DiR...
This paper presents a decision making approach based on a hybrid GA for determining the most efficient number of operators and the efficient measurement of operator assignment in cellular manufacturing system (CMS).The objective is to determine the labor assignment in CMS environment with the optimum performance. We use The GA for getting near optimum ranking of the alternative with accordance to...
The design of a fully-integrated linearized CMOS bidirectional distributed amplifier (DA) based active circulator with broadband distortion cancellation capability is presented. The S21 differential power gain peaks at 7 dB and then rolls off to a unity gain bandwidth of 11.5 GHz. The simulated tunable isolation performance is better than -26 dB. The simulated linearized IIP3 show a 10 dB improvement...
Design consideration for an 80 nm channel length SOI MOSFET employing double step buried oxide (DSBO) is presented. The electrical characteristics and temperature distribution are analyzed and compared with conventional silicon-on-insulator (C-SOI) MOSFETs. The DSBO devices are shown to have better leakage and subthreshold characteristics. Furthermore, the channel temperature is reduced during high-temperature...
In today's technology generations, e.g. 90 and 65 nm, the static power consumption becomes a major contributor to the total power consumption. This paper focuses on the arithmetic level and shows a methodology for a substantial reduction of the static power consumption. Simulations are done in a typical 130 nm technology. Based on the simulation results, the static power in a digital filter is estimated...
Wireless sensor networks are used in many applications like battlefield, patient monitoring, emergence response information and environmental monitoring. To achieve security in WSN, it is important to be able to encrypt the messages sent between sensor nodes. It is required to agree upon a common key before encrypting the messages. The key management task is challenging due to resource constrained...
For a class of chaotic system, general observer based projective synchronization method is presented, which generalizes the scalar observer to a vector observer and extends the scope of application for the observer based projective synchronization method.
Not only does the cyberspace update rapidly, but the new network technology also develops immediately. This trend does not conform to the former cyber-law so that its future development is boundless and unpredictable. Since the connection between the entrepreneurial management and information technology is gradually close and significant, based on the information feedback, the managers are able to...
Carbon Nano Tubes (CNTs) are potential candidate to be used in nano transistors and interconnection inside the ICs. In most of these applications, speed of the carriers is very important. Due to small sizes of CNTs, the mobility of electrons is ballistic. On the other hand because of the superabundant free electrons, most of CNTs are in the degenerate regime, where Boltzmann statistics can not be...
Designing of high voltage LDMOS with a reduced surface field (RESURF) structure have been investigated to achieve the optimum figure of merit, maximum breakdown voltage accompanied with low on resistance. The drift region profile and device geometry plays important role to achieve target breakdown voltage of 80 V. The electrical behaviors of the designed high voltage LDMOS for both on state and off...
