Since protons are not fundamental particles, they produce very large backgrounds in proton-proton collisions. Therefore, supersymmetry searches, the main challenge is to differentiate supersymmetric signals from Standard Model background. Hence, extensive background analysis becomes an important probe obtain information direction of searches. Among variety signatures this direction, single lept...

The evidential reasoning (ER) approach is a method for multiple attribute decision analysis (MADA) under uncertainties. It improves the insightfulness and rationality of a decision making process by using a belief decision matrix (BDM) for problem modelling and the Dempster–Shafer (D–S) theory of evidence for attribute aggregation. The D– S theory provides scope and flexibility to deal with int...

We design an adaptive finite element method (AFEM) for mixed boundary value problems associated with the differential operator A − ∇div in H(div,Ω). For A being a variable coefficient matrix with possible jump discontinuities, we provide a complete a posteriori error analysis which applies to both Raviart–Thomas RT and Brezzi– Douglas–Marini BDM elements of any order n in dimensions d = 2, 3. W...

A start-up is a relatively new and attractive entrepreneurial form that being explored in broader national economy industry context. However, there little knowledge about its strategy, which mainly represented by the business development strategy. The main goal of research to deepen expand strategic background start-ups, preparation condition for strategy later too. partial goals are in-depth d...

Vision-based human identification at a distance in surveillance systems has attracted more attention recently, and its current focus is on face, gait or activity-specific recognition. Based on principal component analysis, this paper makes a simple but efficient attempt to gait recognition. For each gait sequence, an improved background subtraction procedure is first used to accurately extract ...

We present a study of the ionization and thermal structure of neutral hydrogen clouds located in the Galactic halo, immersed in the extragalactic background radiation field, and supposed to be in pressure equilibrium with the surrounding (presumably) hot medium. The problem is solved numerically, but an useful analytical approximation has been derived as well. We discuss the two main parameters...

Gait recognition has recently attracted increasing attention, especially in vision-based human identification at a distance in visual surveillance. This paper proposes a simple but efficient gait recognition algorithm based on statistical shape analysis. For each gait sequence, a background subtraction procedure is used to segment spatial silhouettes of the walking figures from the background. ...
