The minimal grand uni ed supergravity model is discussed. Requiring radiative breaking of the electroweak gauge symmetry, the uni cation of b and Yukawa couplings, a su ciently stable nucleon, and not too large a relic density of neutralinos produced in the Big Bang constrains the parameter space signi cantly. In particular, the soft breaking parameter m1=2 has to be less than about 130 GeV, an...

This paper proposes analytical synthesis of the minimum L2-sensitivity realizations of all-pass digital filters. We first prove that the L2-sensitivity minimization problem can be solved analytically if the all second-order modes of a digital filter are equal. We focus on the fact that the second-order modes of all-pass digital filters are all unity. As a result, it is clarified that the minimu...

The paper describes used techniques, operation characteristics and develops information of the unconventional soft switched active power filter. The power part is based on progressive IGBT’s and high speed voltage and current sensors. The APF is connected in parallel to the AC input of the system, and corrects all loads directly from the AC main. Control unit is based on use of digital signal p...

1 A method for error correction in integegrated circuit (IC) implementations of Boolean functions is described. Additional logic, implementing error correcting codes known from channel coding, corrects both ’hard’ manufacturing errors and ’soft’ temporary errors. Experimental results are presented, with code optimization based on a fast algorithm for Boolean symmetry analysis. Apart from the we...

Supporting advertisements in large publish/subscribe services has an improving influence on the system scalability. The additional application of event routing optimizations based on subscriptions further increases the event throughput and decreases the memory usage of publish/subscribe systems. However, also advertisement-based optimizations can improve these system properties but have been wi...

Boolean Query Mapping Across Heterogeneous Information Sources Kevin Chen-Chuan Chang, Hector Garcia-Molina, Andreas Paepcke* Abstract---Searching over heterogeneous information sources is difficult because of the non-uniform query languages. Our approach is to allow a user to compose Boolean queries in one rich front-end language. For each user query and target source, we transform the user qu...

Statistical analysis tasks are increasingly encountered in the design of digital circuits that implement complex Boolean functions. Examples include analyzing the impact of soft errors, estimating power consumption, and stochastic computation. Common simulation techniques such as quasiMonte Carlo simulation often converge too slowly for large circuits with many inputs, i.e., many dimensions. We...

Existing state-of-the-art switching-based median filters are commonly found to be nonadaptive to noise density variations and prone to misclassifying pixel characteristics at high noise density interference. This reveals the critical need of having a sophisticated switching scheme and an adaptive weighted median filter. We propose a novel switching-based median filter with incorporation of fuzz...

The aim of this paper is to propose a soft consensus model based on interpolative Boolean algebra for group decision making problems. Consensus degrees are calculated on three levels (on pairs of alternatives, alternatives, collective level) by means of pseudo-logical aggregation. The relation of equivalence is employed as a similarity measure among experts' opinions. In fact real-valued realiz...

We explore the use of soft computing and user de ned classi cations in multimedia database systems for contentbased queries. With traditional database systems, objects/tuples are grouped into classes/relations using \hard" membership. Hence, the result of a query to obtain the members of a class is a xed set. With multimedia databases, however, an object may belong to di erent classes with di e...
