Alloy uses a first-order relational logic for modeling designs. The Alloy Analyzer translates Alloy formulas for a given scope, i.e., a bound on the universe of discourse, to Boolean formulas in conjunctive normal form (CNF), and subsequently checks them using propositional satisfiability solvers. We present SERA, a novel algorithm that compiles a relational logic formula for a given scope to a...

The reverse engineering process for VLSI chips is a complex operation that can cost from $10,000 for the simplest chips to hundreds of thousands of dollars for complex chips. In this study, we present an overview of the process of reverse engineering VLSI chips. The study outlines the steps involved in the process of reverse engineering chips as well as the different techniques used to extract ...

The present conditions of classroom instruction to numbers of children still too large to be adequately handled, makes it nearly inevitable that the problem of educafor teachers of backward children should become largely a question of measuring abilities, testing attainments and organising children into more homogeneous grades; and within those grades, diagnosing and treating by individual meth...

A solder fatigue model for the 63Sn/Pb solder alloy has been previously introduced which characterizes the creep fatigue phenomena of the solder by combining nonlinear finite element modelling with experimental thermal fatigue lives of various flip chip assemblies. The model correlates the amount of creep strain energy dissipated per thermal cycle with the characteristic Weibull life of the cri...

The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...

In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. However, the improvement of low cycle fati...
