The current technologies used for DHW production in the city of València (Spain) are mainly gas boiler and immersion electric heater that individual installations, high energy consuming CO2 emitters. There exists a savings potential on based introduction smart systems with Heat Pumps (HP) also generalization collective installations. To this purpose, research aims to deeply analyze different sc...

Methods We have tested on a bench the hygrometric performance of different oxygen high flow therapy systems (OptiFlow/ Airvo Fisher&Paykel, Hydrate OMNI Hydrate inc., Precision flow Vapoterm,). We have used psychrometric method to measure hygrometry. For each condition, we made 3 hygrometric measurements at different moments of the day. The measurements were taken proximal to the simulated pati...

There has been an increasing interest in applying machine learning methods in urban energy assessment. This research implemented six statistical learning methods in estimating domestic gas and electricity using both physical and socio-economic explanatory variables in London. The input variables include dwelling types, household tenure, household composition, council tax band, population age gr...

Investigations for the melt growth gallium-antimonide (GaSb) semiconductor crystals are underway at the US Air Force Research Laboratory at Hanscom Air Force Base by the vertical gradient freeze (VGF) method utilizing a submerged heater. Electromagnetic stirring can be induced in the gallium-antimonide melt just above the crystal growth interface by applying a weak radial electric current in th...

This paper uses household data from the 1988 to 2000 U.S. Consumer Expenditure Surveys to examine the determinants of new vehicle purchases, where vehicles are disaggregated into four categories: cars, trucks, vans, and sport-utility vehicles (SUVs). In particular, it analyzes the effect on vehicle choice of gas prices at time of vehicle purchase relative to that of gas prices in previous quart...

Heat transfer and fluid flow due to buoyancy forces in a partially heated enclosure using nanofluids is carried out using different types of nanoparticles. The flush mounted heater is located to the left vertical wall with a finite length. The temperature of the right vertical wall is lower than that of heater while other walls are insulated. The finite volume technique is used to solve the gov...

A planar Bi–Sb multijunction thermal converter was fabricated on the LPCVD Si3N4/SiO2/Si3N4-diaphragm, prepared by silicon bulk micromachining, which thermally isolated a bifilar Ptor NiCr-heater and the hot junctions of a Bi–Sb thermopile from the silicon substrate. The voltage responsivity, the ac–dc transfer difference, and the fluctuations of the output thermoelectric voltage and heater res...
