Multi-objective evolutionary feature selection for online sales forecasting

LUIS MIRALLES
Sales forecasting uses historical sales figures, in association with products characteristics and peculiarities, to predict short-term or long-term future performance in a business, and it can be used to derive sound financial and business plans. By using publicly available data, we build an accurate regression model for online sales forecasting obtained via a novel feature selection methodology composed by the application of the multi-objective evolutionary algorithm ENORA (Evolutionary NOn-dominated Radial slots based Algorithm) as search...

An exploratory measure of multiple motives

Mark Rubin
An exploratory measure of multiple motives (EMMM) is presented.  The EMMM enables researchers to make quick exploratory assessments of a relatively large number of general motives.  It includes 14 single-item self-report measures that assess self-control, self-esteem, sensation-seeking, the need for acquisition, the need for affect, the need for cognition, the need for meaning, the need for power, the need for precision, the need for self-consistency, the need for structure, the need for uniqueness, the need...

Development of Intelligent Traffic Control System by Implementing Fuzzy-logic Controller in Labview and Measuring Vehicle Density by Image Processing Tool in Labview

Viral Patel & Maitri Patel
we have described a whole new approach of rationalization of existing traffic control systems by means of Fuzzy logic based control system and Vision sensors based vehicle counting method. As Conventional traffic control systems are inefficient because they provide fixed time-delay though no vehicle is present in that lane. So it results in congestion of vehicles on the adjacent side. And it generates the Noise and Air pollution, which is undesirable and not favorable. In...

PENGGUNAAN EKSTRAK DAUN BINAHONG (BASSELA RUBRA LINN) SEBAGAI ZAT PEKA CAHAYA TiO2-NANO PARTIKEL DALAM DYE-SENSITIZED SOLAR CELL (DSSC)

Hardani M.Si
Abstrak Dye-sensitized solar cell (DSSC) merupakan salah satu dari sel-sel listrik fotokimia yang terdiri dari fotolektroda, pewarna, elektrolit, dan counter elektroda. Tujuan menggunakan pewarna pada DSSC guna memperluas spektrum absorpsi pada cahaya tampak karena cahaya tampak memiliki sekitar 96% energi dari cahaya matahari.Telah dilakukan fabrikasi DSSC dengan menggunakan dye ekstrak daun binahong (Bassela rubra linn) dengan variasi perendaman TiO2 dengan teknik pelapisan Spin Coating. Variasi perendaman TiO2 yang digunakan yaitu substrat TiO2 yang direndam dalam...

Fabrication of Dye Natural As a Photosensitizers in Dye-Sensitized Solar Cells (DSSC)

Hardani M.Si
Abstract The purpose of this study was to obtain optical properties (absorption spectrum) and electrical properties (photoconductivity) of organic dyes in DSSC performance. optical and electrical properties were tested by using UV-Visible Spectrophotometer and Elkahfi 1601 PC 100 / IV meter, respectively, while Keithley Type 2600A is used for the characterization of DSSC. This study is a great base to explore and investigate the development of DSSC solar cells using natural dyes (organic). Spectra optimal...

PENGARUH KONSENTRASI RUTHENIUM (N719) SEBAGAI FOTOSENSITIZER DALAM DYE-SENSITIZED SOLAR CELL (DSSC) TRANSPARAN

Hardani M.Si
Abstrak DSSC (Dye-sensitized solar cells) adalah suatu devais yang mampu mengubah energi matahari menjadi energi listrik dengan memanfaatkan dye ruthenium (N719) sebagai sensitizer. Pada penelitian ini telah berhasil dibuat elektroda kerja berbahan titanium dioksida (TiO2) ukuran nanopartikel berbentuk film tipis (thin film) yang dideposisikan diatas gelas transparan konduktif FTO (fourine doped-tin oxide) dengan metode spin coating. Dari hasil pengujian menggunakan solar simulator AM 1.5G (100 mW/cm2) diperoleh overall conversion efficiency mencapai  0,298 % dengan tegangan...

A phylogenetic tree produced with the Neighbor-joining method based on the 16S rRNA gene sequences of Legionella from river water samples. The numbers of the sequences in this tree refer to the numbers in the DGGE. The scale bar represents 200% of nucleotide sequence divergence. The numbers at the selected nodes indicate the levels of bootstrap support (percentage) based on 1000 re-sampled data sets (only values greater than 70% shown).

Corrosion protection behaviour of silica–titania hybrid coatings embedded with silica nanoparticles

R. V. Lakshmi & S. T. Aruna
Hybrid sol-gel coatings prepared using organically modified silanes and corrosion inhibitors are used for the surface protection of metals and alloys. This paper focuses on the corrosion behaviour and compatibility of silica nanoparticles as nanocontainers in silica–titania hybrid system. The surface protection of the alloy is improved by using silica nanoparticles as nanocontainers for cerium (III) inhibitor. The hybrid coating system protected AA2024-T3 alloy effectively against corrosion when immersed in NaCl solution for prolonged hours....
