Significant interest exists within the military in moving towards an integrated services environment where traditional network services such as ftp, telnet, and e-mail can co-exist with real-time services such as voice, video, and satellite imagery. Multicast routing is an effective means of providing the efficient utilization of network resources required to realize such an environment. Tradit...

The interior trust region algorithm for convex quadratic programming is further developed. This development is motivated by the barrier function and the \center" path-following methods, which create a sequence of primal and dual interior feasible points converging to the optimal solution. At each iteration, the gap between the primal and dual objective values (or the complementary slackness val...

An effective XML cluster method called neighbor center clustering algorithm (NCC) is presented in this paper, whose similarity is obtained through both structural and content information contained in XML files. Structural similarity is firstly measured by frequency-path model and its similarity calculation algorithm with position and frequency weight by longest common subsequence is introduced....

This paper presents design of a defected ground structure coupled miniaturized dual-mode bandpass filter realized using a square patch. Two slots orthogonal to each other are cut on the patch to increase the path length of the fundamental mode while keeping the second mode current path almost unaffected. An inclined aperture cut on the ground plane right beneath the center of the patch is used ...

We observe a curious property of dual versus primal-dual path-following interior-point methods when applied to unbounded linear or conic programming problems in dual form. While primal-dual methods can be viewed as implicitly following a central path to detect primal infeasibility and dual unboundedness, dual methods can sometimes implicitly move away from the analytic center of the set of infe...

Lewis acid promoted reactions of allylsilanes and allenylsilanes provide access to important building blocks for natural product synthesis.1 For example, trimethylsilylallenes function as propargylic anion equivalents in aldehyde addition reactions (eq 1, Path A).2 If the silicon center is sterically congested, the normal addition pathway is suppressed and functionalized dihydrofurans are produ...

Let α be a Morse closed 1-form of a smooth n-dimensional manifold M. The zeroes of α of index 0 or n are called centers. It is known that every non-vanishing de Rham cohomology class u contains a Morse representative without centers. The result of this paper is the one-parameter analogue of the last statement: every generic path (αt)t∈[0,1] of closed 1-forms in a fixed class u 6= 0 such that α0...

BACKGROUND The optimal iliac screw path was determined to provide references for lumbosacral-pelvic reconstruction. METHODS Radiographic data of 100 patients with normal pelvis were selected for this study. Four paths were designed. Paths A, B, and C were from the starting point of the crossing point of the chiotic line and posterior iliac crest (CLIC, located at 24.0 mm above the posterior s...
