this paper proposes an optimal transmission expansion planning (tep) which is based on determining share of each line in merchandizing surplus (ms) of system, determining by independent system operator (iso). the more share of a line in ms of system denotes the priority of a line for expansion. the procedure of determining ms of each line in a power system is based on determining the ms share o...

In this paper we introduce some new subclasses of the class σ of bi-univalent functions and obtain bounds for the initial coefficients of the Taylor series expansion of functions from the considered classes.

Using binomial coefficients a general series expansion formula is established for the integral

A description of the Dolphin D330 Cluster Adapter Card and its main components and features will be given. The focus will be on the differences between the previous D320 and the new D330.

Two different sufficient conditions are given for the convergence of the Magnus expansion arising in the study of the linear differential equation Y ′ = A(t)Y . The first one provides a bound on the convergence domain based on the norm of the operator A(t). The second condition links the convergence of the expansion with the structure of the spectrum of Y (t), thus yielding a more precise chara...

In this paper we give a brief overview of the Webis group’s participation in the TREC 2011 Sessions track with an extended version of our last year’s approach [HSV10]. The basic idea can be described as a conservative query expansion based on terms used in previous queries or terms contained in clicked snippets. Furthermore, a query’s result set is reduced by removing documents shown for previo...

We report our system and experiments for the realtime Adhoc task in the 2011 MicroBlog track. Our goal is to develop effective technique to retrieve relevant tweets that have been posted recently. In particular, we propose a time-­sensitive term weighting strategy that can favor tweets in hot-­discussed time and a document length related weighting method that can favor long tweets which are mor...
