We propose a hybrid genetic algorithm for the xed channel assignment problem with limited bandwidth. A local optimization algorithm was devised to enhance the genetic algorithm's ne-tunning. In a matrix representation, the local optimization algorithm improves on a chromosome by horizontal and vertical moves of channels. The crossover is directly performed on two-dimensional matrices. Experimen...

We studied the variation of Newton ́s gravitational constant G, using the experimental data and the scalar-tensor theory for gravitation. We search for a fine tunning to match the datas and find possible scenarios for the history of this constant.

Abstract The aim of the present work is synthesis and optimal tunning a PID controller designed to control displacement volume an axial-piston pump intended for hydraulic systems with open circulation. controlled in real-time through system developed by authors based on electro-hydraulic proportional valve (replacing conventional hydro-mechanical controller) industrial controller. experimental ...

Penelitian ini didahului dengan melakukan LTE Drive Test sebanyak dua kali pada Jalan Daan Mogot layanan yang berbeda, dan mendapatkan nilai persentase 95% RSRP, SINR, RSRQ tidak memenuhi standar key performance indicator dari operator. Pada jalan juga ditemukan beberapa kasus seperti radio link failure, handover connection drop serta 6 area bad spot. Perbaikan telah dilakukan Aplikasi Atoll me...

Layersis an open source neural network toolkit aim at providing an easy way to implement modern neural networks. The main user target are students and to this end layers provides an easy scriptting language that can be early adopted. The user has to focus only on design details as network totpology and parameter tunning.

Ultrahigh surface area carbons (3000 – 3500 m g) have been obtained via chemical activation of polypyrrole with KOH. The carbon materials exhibit large pore volumes (up to ~2.6 cm g) and possess two pore systems; one of pores in the micropore range (~ 1.2 nm) and the other in the small mesopore range (2.2 – 3.4 nm). Some carbons also possess a significant proportion of 0.6 nm pores. Tunning of ...

Next-generation data centric applications often involve diverse datasets, some very large while others may be of moderate size, some highly structured (e.g., relations) while others may have more complex structure (e.g., graphs) or little structure (e.g., text or log data). Facing them is a variety of storage systems, each of which can host some of the datasets (possibly after some data migrati...

The use of software agents as Database Management System components lead to database systems that may be configured and extended to support new requirements. We focus here with the self-tuning feature, which demands a somewhat intelligent behavior that agents could add to traditional DBMS modules. We propose in this paper an agent-based database architecture to deal with automatic index creatio...
