A new method of integrating arduino with relay and transistor for home energy management system is proposed. The arduino is developed as a controller to manage the lamp, fan and airconditioner. It correspond the relay, lamp and fan via PIR sensor, and air conditioner via temperature sensor. The energy consumed by the electrical appliances can be saved by at least 1.5% with the implementation of...

Dengan mesin penyejuk udara ini pengaturan dalam ruangan akomodasi kapal dapat dilakukan sesuai dengan suhu ruang yang diinginkan. Tujuan dari penelitian adalah untuk mengetahui mengapa tidak tercapainya diharapkan, faktor apa membuat tekanan kondensor menjadi tinggi dan penyebab penanganan air conditioner di optimal. Sistem kurang mendapat perawatan pemeliharaan teratur, sehingga proses pendin...

Thermodynamics is a funny subject. The first time you go through it, you dont understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don't understand it, but by that time you are so used to it, it doesn't bother you any more. Global climate results from a thermodynamic interaction b...

With the aim of identifying the fungus microbiota in air conditioners in intensive care units (ICUs) within public and private hospitals in Teresina, Piauí, solid material was collected from ten different ICUs. Thirty-three species of Moniliaceae and Dematiaceae were isolated, which was the first report of these in Piauí. High frequencies of Aspergillus niger Van Tieghem (60%), Aspergillus fumi...

The aim of this in vitro study was to evaluate by scanning electron microscopy the morphological aspects of the enamel of primary teeth after etching with 36% phosphoric acid or a non-rinse conditioner. Ten naturally exfoliated anterior primary teeth were selected. The samples were subjected to prophylaxis with pumice paste and water using a low-speed hand piece. Etching was done on the buccal ...

The paper focuses on the dynamic pricing game of the duopoly air conditioner market with disturbance in demand and analyzes the influence of disturbance on the dynamic game system. Considering the demand for products, such as air conditioner, varies with different seasons, we assume three cases based on the condition of disturbance, including growth market (Case 1), decliningmarket (Case 2) and...
