This paper attempts to analyze the propagation characteristics of radio signal inside a partially open drain environment using an empirical approach. The proposed research topic concerns a unique situation in several Asian countries because the drainage systems in these countries differ notably from those in the US and Europe in that the former are partially open on the top while the latter are...

We present an approach for multi-layer preparation to perform microstructure analysis of a Li-ion cell anode active material using synchrotron tomography. All necessary steps, from the disassembly of differently-housed cells (pouch and cylindrical), via selection of interesting layer regions, to the separation of the graphite-compound and current collector, are described in detail. The proposed...

A reference counting garbage collector cannot reclaim unreachable cyclic structures of objects. Therefore, reference counting collectors either use a backup tracing collector seldom, or employ a cycle collector to reclaim cyclic structures. Recently, the first on-the-fly cycle collector, that may run concurrently with program threads, was presented by Bacon and Rajan [3]. This demonstrated the ...

the shape of a solar collector is an important factor in solar-to-thermal energy conversion. conical shape is one of the stationary and symmetric shapes that can be employed as a solar water heater. flow rate of working fluid on the solar collector has an important effect on the efficiency of the collector. the present study is an experimentally investigated of the performance of the solar coni...

The goal of this paper is to focus on the effect of fluid flow, solution chemistry and surface morphology of fibrous media (in terms of roughness and charge heterogeneity) on colloid removal. A theoretical framework on the role of flow velocity on particle deposition to cylindrical substrate is presented. Existing theories related to particle attachment onto cylindrical substrates and on the ef...

The new approach to solving diffusion problems using multidimensional integral equations (equations containing multiple integrals) proposed in Part 1 is used to address microelectrode problems with two types of electrode geometry: two-dimensional linear diffusion and cylindrical diffusion in a thin-layer cell. The electrochemical current transients and cyclic voltanunograms at a microband elect...

Solar thermal water heating systems have been developed to replace conventional heating. Therefore, the design of a parabolic cylinder collector-type solar unit with coil-shaped heater (absorber) has carried out. The cylindrical collector is made an aluminum plate covered reflective sticker and base insulated, having diameter, height, length, position focal point 150, 60, 200, 22.4 cm, respecti...

A sensitive detector and pressure gauge for uranium hexafluoride in high-vacuum systems is described. Negative surface ionization of UF(6) occurs on ribbon filaments operated at temperatures too low for electron emission to be significant. The ion current measured on a cylindrical collector surrounding the filament assembly varies regularly with UF(6) pressure below 10(-3) Torr. Different filam...

The objective of the present research work is to investigate a novel high-efficiency nanofluid in solar dish concentrator by using numerical model developed. working fluids examined consisted soybean oil-based MXene different concentrations (i.e. 0.025, 0.075 and 0.125 wt%) pure oil. studied nanofluids yielded excellent thermal properties such as high conductivity heat capacity, which were two ...
