-Recent work in code optimization has led to development of new unified optimizing transformations[6,7]. Application of these transformations requires solution of bi-directional data flow problems over program flow graphs using iterative solution techniques. Appropriate characterization of program loops in the flow graph is necessary so as (i) not to hinder code movement, etc., and (ii) restric...

The trajectory planning of redundant robots is an important area of research and efficient optimization algorithms are needed. The pseudoinverse control is not repeatable, causing drift in joint space which is undesirable for physical control. This paper presents a new technique that combines the closed-loop pseudoinverse method with genetic algorithms, leading to an optimization criterion for ...

Logistic Regression (LR) has been widely used in statistics for many years, and has received extensive study in machine learning community recently due to its close relations to Support Vector Machines (SVM) and AdaBoost. In this paper, we use a modified version of LR to approximate the optimization of SVM by a sequence of unconstrained optimization problems. We prove that our approximation wil...

A district heating system is a centralized energy that supplies heat to end users such as buildings and industrial facilities. This may have multiple sources, complex distribution network, large number of users. Moreover, the utilization processes entail tumultuous thermal dynamics. Therefore, modelling optimizing generally demands arduous labour necessitates powerful computing resources. To ov...

—With the development of intelligent substation in China, it becoming more important that the conformance testing of IEC 61850 is used to guarantee the interoperability between intelligent electric devices. In view of the current intelligent substation IEC 61850 conformance testing did not form a closed loop, which led to the lacking of comprehensiveness and integrity, a closed-loop conformanc...

The glycoprotein (GP) of ebolaviruses participates in a critical membrane fusion process to establish infection of a cell and therefore, represents an important target of both vaccines and antivirals. The latest reports on pan-ebolavirus monoclonal antibodies in small animal models may offer promising outcomes and insight into how best to target the GP in vaccine and antiviral discovery.

In [6], we proved an asymptotic O(n−α/(α+1)) bound for the approximation of SU(N) loops (N ≥ 2) with Lipschitz smoothness α > 1/2 by polynomial loops of degree ≤ n. The proof combined factorizations of SU(N) loops into products of constant SU(N) matrices and loops of the form eA(t) where A(t) are essentially su(2) loops preserving the Lipschitz smoothness, and the careful estimation of errors i...

this study presents the natural dye recovery from various biodegradable temple and household wastes. the raw material for colour extraction consisted residual flowers and garlands from various temples as well as onion and vegetables peels from vegetable markets, university hostels, and households, which were washed, dried, crushed, and sieved. the extracted natural colours were produced by mean...

This work is an example of application of nonlinear programming to a problem of three-dimensional trajectory optimization for multistage launch vehicles for geostationary orbit missions. The main objective is to minimize fuel consumption or equivalently to maximize the payload. The launch vehicle considered here, Europa-II, consists of 5 thrust phases and 2 coast phases. Major parameters of the...

It is essential for a robot to be able to detect revisits or loop closures for long-term visual navigation. A key insight explored in this work is that the loop-closing event inherently occurs sparsely, i.e., the image currently being taken matches with only a small subset (if any) of previous images. Based on this observation, we formulate the problem of loop-closure detection as a sparse, con...
