Most of the students in junior high school find it difficult to learn English, when asked practice speaking a text procedure front class they feel afraid and not confident. This research aims out effectiveness learning procedures by using video vlog at SMPN 7 Muara Bungo. The methodology this is quasi-experimental quantitative research. analysis method uses data collection descriptive test. par...

A strategy for toughening epoxy thermosets via topological rearrangement of cross-linked networks is presented. Amine-cured systems were modified by mixing partially reacted substructures (mPRS), which synthesized curing tetraglycidyl ether diaminodiphenylmethane (TGDDM) and polyether monoamine (Jeffamine M1000) to provide free unbound surfaces that enhance protovoid formation during deformatio...

BACKGROUND Central to the design of a randomised controlled trial is the calculation of the number of participants needed. This is typically achieved by specifying a target difference and calculating the corresponding sample size, which provides reassurance that the trial will have the required statistical power (at the planned statistical significance level) to identify whether a difference of...

In this paper, structural topology optimization is addressed through Genetic Algorithms. A set of designs is evolved following the Darwinian survival-of-ttest principle. The standard crossover and mutation operators are tailored for the needs of 2D topology optimization. The genetic algorithm based on these operators is experimented on plane stress problems of cantilever plates: the goal is to ...

Balanced scorecard helps organizations to streamline vision and strategy with business activities and measures actual organizational performance against preset goals. In addition this instrument is used to assess financial processes, customer relations, internal business processes and learning and growth characters of an organization. The purpose of this study is to recognize the role balanced ...

This paper presents a gene selection method for classification of gene expression data. First, a fFeature selection techniques based on t-test statistic is used applied in order to select the n topranked significant genes. Then, a combination of Genetic Algorithm (GA) and /Support Vector Machines (SVM) is used to further select significant genes to the resulting set of genes obtained from t-tes...

CPU scheduling is one of the most primary and essential part of any operating system. It prioritizes processes to efficiently execute the user requests and help in choosing the appropriate process for execution. Round Robin (RR) & Priority Scheduling(PS) are one of the most widely used and acceptable CPU scheduling algorithm. But, its performance degrades with respect to turnaround time, waitin...

Evolutionary computation techniques, which are based on a powerful principle of evolution: survival of the ttest, constitute an interesting category of heuristic search. In other words, evolutionary techniques are stochastic algorithms whose search methods model some natural phenomena: genetic inheritance and Darwinian strife for survival. Any evolutionary algorithm applied to a particular prob...

Evolutionary algorithms (EAs), which are based on a powerful principle of evolution: survival of the ttest, and which model some natural phenomena: genetic inheritance and Darwinian strife for survival, constitute an interesting category of modern heuristic search. This introductory article presents the main paradigms of evolutionary algorithms (genetic algorithms, evolution strategies, evoluti...
