In this work, a new and effective algorithm called hybrid teaching–learning-based optimization (TLBO) charged system search (CSS) algorithms (HTC) are proposed to solve engineering mathematical problems. The CSS is inspired by Coulomb Gauss’s electrostatic laws of physics as well the Newtonian mechanic motion. TLBO interaction between teacher student in classroom. Usually, gets trapped local op...

The objective of this paper is to present an optimal design for single-layer barrel vault frames via improved magnetic charged system search (IMCSS) and open application programming interface (OAPI). The IMCSS algorithm is utilized as the optimization algorithm and the OAPI is used as an interface tool between analysis software and the programming language. In the proposed algorithm, magnetic c...

In planning and managing water resources, the implementation of optimization techniques in operation reservoirs has become an important focus. An optimal reservoir operating policy should take into consideration uncertainty associated with uncontrolled inflows. The charged system search (CSS) algorithm model is developed present study to achieve optimum for current reservoir. aim minimize cost ...

BACKGROUND The enriched biological activity information of compounds in large and freely-accessible chemical databases like the PubChem Bioassay Database has become a powerful research resource for the scientific research community. Currently, 2D fingerprint based conventional similarity search (CSS) is the most common widely used approach for database screening, but it does not typically incor...

INTRODUCTION Ishikawa and Jefferson are the two most commonly used systems used for the classification of cavernous sinus syndrome (CSS). However, relative utilities of these two classification systems have not been evaluated in detail in developing countries. In this study, we compared relative utilities of these two classification schemes in the evaluation of CSS. OBJECTIVE To compare the u...

Due to its anti-jamming capability, chirp spread spectrum (CSS) technique has attracted much attention in the area of wireless communications. However, there has been little rigorous analysis for the anti-jamming performance of CSS-based communication systems. In this paper, we present analytic results on the anti-jamming performance of a CSS-based system: BER expressions are derived for a CSS-...

A technique to prove termination of term rewrite systems, or more precise, constructorsystems (CSs) is presented.Soundnessof this technique is proved and it is described how the technique can be performed automatically for a subclass of the CSs. Whereas simplification orders fail in proving termination of CSs that are not simply terminating, the presented technique may still automatically prove...
