A modular simulation system (MSS) for the scheduling of semiconductor wafer fabrication facilities (fabs) is discussed. Firstly, the general structure model (GSM) for modeling a semiconductor wafer fab, composed of a configurable definition layer, a physical layer, a process information layer and a scheduling layer, is proposed. Secondly, a data-based dynamic modeling method is given. Thirdly, ...

Given an over-constrained system, a Maximal Satisfiable Subset (MSS) denotes a maximal set of constraints that are consistent. A Minimal Correction Subset (MCS, or co-MSS) is the complement of an MSS. MSSes/MCSes find a growing range of practical applications, including optimization, configuration and diagnosis. A number of MCS extraction algorithms have been proposed in recent years, enabling ...

A common approach to design diagnostic systems is to use residual generators. These generators are usually constructed considering all the model equations. However, there are several advantages of instead consider small subsets of model equations, so called minimal structurally singular (MSS) sets of equations. This paper presents a new method for finding residual generators for MSS sets. A spe...

The Merkle signature scheme (MSS) is an interesting alternative for well established signature schemes such as RSA, DSA, and ECDSA. The security of MSS only relies on the existence of cryptographically secure hash functions. MSS has a good chance of being quantum computer resistant. In this paper, we propose CMSS, a variant of MSS, with reduced private key size, key pair generation time, and si...

© 2010 Jong-Min Park et al. 255 Interference scenarios and methodologies between a terrestrial mobile service (MS) system and mobile-satellite service (MSS) system in a co-channel environment are established. Taking into account a practical deployment situation for both systems, we perform computational simulation of interference in terms of carrier-tointerference ratio (C/I) and interference-t...

Exposure to maternal idiotypes (Ids) or antigens might predispose a child to develop an immunoregulated, asymptomatic clinical presentation of schistosomiasis. We have used an experimental murine system to address the role of Ids in this immunoregulation. Sera from mice with 8-wk Schistosoma mansoni infection, chronic (20-wk infection) moderate splenomegaly syndrome (MSS), or chronic hypersplen...

Mouse stromal cell lines (MSS lines) have been established from the spleens of newborn mice in culture at a low serum concentration. These MSS lines support the proliferation and differentiation of the erythroid progenitor cells from mouse fetal livers and bone marrow in a semisolid medium in the presence of erythropoietin. Larger colonies of over 1,000 benzidine-positive erythroid cells were d...

A questionnaire concerning musculoskeletal symptoms (MSS) and working environment was answered by 100% of 103 car mechanics in 12 different garages. Almost all the mechanics had been troubled with MSS at work the past year. The most common MSS were symptoms from the low back, neck, head and shoulders. When asked which symptoms had been most troublesome at work most mechanics reported symptoms f...
