Keywords: 3C Intelligent home appliance CCD a b s t r a c t This study is a creative and initial work focused on designing an intelligently automatic detecting and sensor system for home appliances being smartly interactive with mankind with speech in the living space. Since the tide of automation flowed over the industry, manufacturing business, even the living space of mankind resulting from ...

Background and Objective: Quality control is one of the most important components in order to improve quality assurance in laboratories during analytical steps. For this purpose, coefficient of variation plays an important role. Due to the fast improvement in technology, application of inferential statistics for the comparisons ...

This research article illustrates a numerical study of single stage coaxial as well as inline Inertance-Type Pulse Tube Refrigerator (ITPTR). In this present work a computational fluid dynamic (CFD) approach has been adopted for numerical simulation purpose. The detail analysis of cool down behaviour, heat transfer at the cold end and the pressure variation inside the whole system has been carr...

Cool water packs are a useful alternative to ice packs for preventing unintentional freezing of vaccines during outreach in some situations. Current guidelines recommend the use of a separate refrigerator for cooling water packs from ambient temperatures to prevent possible heat degradation of adjacent vaccine vials. To investigate whether this additional equipment is necessary, we measured the...

in the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. the importance of such energy optimization schemes stems from the environmental impacts of freon (r-12) used as the working refrigerant in household refrigerator – fre...

Thermoacoustics describes energy conversion processes, activated by interaction temperature oscillation, accompanying the pressure oscillation in a sound wave, with solid boundaries. In ordinary experience this interaction of sound and heat cannot be observed, because of the very low temperature differences, but under suitable conditions, it can be emphasized and amplified to create remarkable ...

Because of high growth in economy and rapid increase in energy consumption , the government has made efforts to resolve the difficulties of the shortage of energy by restricting the amount of electrical energy consumption for home electrical products and several products consuming energy. Especially, the rules specified how the amount of electrical energy consumption was tested is expected to r...

The replacement of the 30-year-old Philips cryogenerator with a modern LINDE-1630 helium refrigerator is an important component of TRIUMF’s ongoing 500 MeV cyclotron refurbishing program. Two 10.7 m long cryopanels are cooled with liquid helium rather than with 17 K helium gas, as was the case with the cryogenerator. This has increased the pumping speed and, respectively, improved the vacuum in...

Abstract The purpose is to study the design method of smart refrigerator man-machine interface. adopts conjoint analysis, starting from human-machine interface refrigerator, and splitting orthogonally reorganizing main components element types interface, allowing users score virtual experiment scheme statistical data, calculate utility value each type, analyzes user preference in then draws pri...
