Aumann equilibrium is a game situation from which no coalition of players has a joint deviation that improve the payoff of each member of the coalition. Congestion games has a large field of applications. An evolutionary technique for detecting Aumann equilibrium in this class of games is presented. The experiments prove the effectiveness of the proposed technique.
In this paper, we discuss a development of control and sensing platform for an on-chip single cell evaluation by magnetically driven microtool (MMT). The design and fabrication of the MMT is shown. Through the basic experiments, the advantage of the proposed platform, the performance of the position control (positioning accuracy: 30 μm), and the force sensing (sensing accuracy: 100 μN) of the MMT...
This paper reports a novel and versatile hybrid microassembly technique that applies water mist on the surface of microparts to assist alignment of microchips. This technique combines the traditional robotic pick-and-place technique and self-assembly technique. Two different approaches are studied: 1) mist-last where a 200μm × 200μm × 70μm SU-8 chip is placed roughly on another chip of the same size...
Silicon and polysilicon are both susceptible to fatigue. It might have been once believed in the beginning of micro electro-mechanical systems (MEMS) technology that silicon is a brittle material with almost unlimited fatigue lifetime. However, recent researches revealed many evidences of fatigue fracture, which is potentially a serious threat for the reliability of MEMS structures Although many MEMS...

Highly semi-polar (101̅3) oriented and fine structural AlN films were successfully prepared on silicon substrate by rf magnetron sputtering in this research. The dependence of the nitrogen concentrations and the material characteristics of the films (crystalline structure and micro morphology) were investigated. The crystalline structure of the films was determined by X-ray diffraction (XRD) and the...
We present a non-traditional CMOS inverter composed a junctionless (JL) NMOSFET and an N+-N--P transistor which with simple process and high integration density in this paper. In the non-traditional CMOS inverter the JL NMOSFET serves as driver and the N+-N--P transistor serves as load, respectively. Based on the measurement date of the N+-N--P transistor published, we draw the load line of the non-traditional...
In this study, we propose a novel bulkSi-based device called dual-channel body-tied (DCBT) MOSFET using the self-aligned process without any extra masks. It reveals that our proposed DCBT FET has excellent S.S., decreased Isd,leak, lower Rsd, reduced Jg,limit, smaller lattice temperature, and higher thermal stability when compared with its DC counterpart. And, for the first time, we will investigate...

With the electricity reform deepening, China has established three-level power markets that are national, regional, and provincial electricity markets. Targeted a certain provincial power company, this paper analyzes the goals for establishing regional electricity market, its bidding and transaction models during the initial stage, and its effects to the operation of provincial power companies. This...
Strained engineering in nano process technology is considered to be a promising enhancements on the electric characteristics of MOSFET devices. Both tensile and compressive strains are applied to NMOS and PMOS individually using silicon nitride as contact etching stop layer (CESL). As appeared in this study, the electrical characteristics are to be compared with or without strain on 10μm/10μm (channel...

This paper proposes an Online Customized Bundling and Pricing (OCBP) strategy, which provides each customer a particular bundle with corresponding price, for e-tailers to selling more goods and gaining more profits. We model the OCBP problem as a mixed-integer programming and design a heuristic algorism to solve the problem. Numerical studies show that a possible profit gain of 15-45 per cent could...
Classical TOPSIS method is widely used as a simple calculation, reasonable assessment, and flexible application method. However this method has a shortcoming: it can not rank the point in the perpendicular of the ideal point and negative ideal point. Improved VIKOR algorithm can not rank the point of the same distance to the ideal point. The improved algorithm Angle measurement method only consider...
This paper considers a size constrained version of the undirected feedback vertex set problem motivated by placing wavelength converters on a WDM network efficiently, and proves that this problem is NP-complete even in several special cases. Moreover, the paper presents a simple approximation algorithm for a minimization version of the problem using an algorithm for the original minimum undirected...
Complexity theory typically studies the complexity of computing a function h(x) : {0, 1}m → {0,1}n of a given input x. We advocate the study of the complexity of generating the distribution h(x) for uniform x, given random bits. Our main results are: (1) Any function f : {0, 1}ℓ → {0,1}n such that (i) each output bit fi depends on o(log n) input bits, and (ii) ℓ ≤ log2 (αnn) + n0.99, has output distribution...
We give the first improvement to the space/approximation trade-off of distance oracles since the seminal result of Thorup and Zwick [STOC'01]. For unweighted graphs, our distance oracle has size O(n5/3) = O(n1.66⋯) and, when queried about vertices at distance d, returns a path of length 2d + 1. For weighted graphs with m = n2/α edges, our distance oracle has size O(n2/3√α) and returns a factor 2 approximation...
Novel lazy Lauritzen-Spiegelhalter (LS), lazy Hugin and lazy Shafer-Shenoy (SS) algorithms are devised for Gaussian Bayesian networks (BNs). In the lazy algorithms, the clique potentials and separator potentials are kept in combinable decomposed form instead of combined to be a single valuation in conventional junction tree algorithms. By employing decomposed form potentials, the independence relations...
