CuAlOdos thin films are prepared on Si or sapphire substrate by sol-gel method using two kinds of sols. In the case of acetate sol, XRD peaks of CuAlO2 observed at annealing temperature of 800-950 ?C on both Si and sapphire substrates. In contrast, in the case of the films prepared using nitrate on Si substrate, XRD peaks of CuAlO2 have been observed only at the annealing temperature of 800-850 ?C. At annealing temperature of 850?C, peaks of other species have been observed beside the CuAlO2 peaks, then, the CuAlO2 peaks disappeared at annealing temperature of 900 °C with increasing in intensity of the other peaks. Intensity of the other peaks decreased at annealing temperature of 950 ?C with appearance of broad SiO2 peak. In the present, we ascribe these peaks as metal silicide.
115 The brand new Relationships anywhere between Spatial Build and Homes Rates
Residential property speed has got the comprehensive functions away from metropolitan space, representing brand new personal and you will financial options that come with the metropolis. Correctly, home price can be utilized since the an indicator, that can pick the changes out of spatial build and you can socioeconomic differences for the reason that urban invention. This research attempted to mention the alterations in the property rate by a different sort of street design. Methodologically, it used Space Sentence structure, that will interpret urban spatial construction totally, to identify the relationship between your forms of roadway sites and you can land rates. The result of the fresh regression studies displayed this new ‘consolidation directory away from Area Syntax are statistically extreme and it has an effective strong relationship that have home price. When your combination worthy of are high, belongings rates grows proportionally. Then, playing with regression formula, they attempted to expect the newest belongings speed change each and every off the latest loads related this new ways that will be newly unwrapped. The research strategies or investigation show feel the advantageous asset of forecasting the alterations within the residential property rates into the a simple way. Concurrently, it does subscribe to coordinators and you may enterprise managers to determine related polices and you may smoothing urban regeneration systems as a result of increasing customers information by the getting possible overall performance and you may advantages within home rate before execution regarding metropolitan regeneration and invention ideas.
114 Plasma Properties Affect Neon Pipe Plasma Antenna Results
This paper gift ideas the analysis towards the results off monopole antenna having fluorescent tubes. Inside look, the newest simulator and you may fresh method is carried out. The fluorescent pipe with different length and you will size is customized playing with Pc Simulation Technology (CST) app and features off antenna parameter is simulated regarding the software. CST was applied to imitate antenna details instance come back losses, resonant regularity, acquire and directivity. Vector Circle Analyzer (VNA) was utilized to measure brand new come back loss of plasma antenna within the purchase to examine the new simulator overall performance. On the simulator and you may try out, the production regularity is set which range from step 1 Gigahertz so you can ten Gigahertz. The results demonstrate that the latest come back loss of plasma antenna alter when sized neon hoses is actually ranged, correspond to the many plasma features. It implies that various other opinions from plasma features including plasma volume and you can accident regularity brings huge difference consequence of come back loss, acquire and directivity. Toward gain, the costs are priced between 2.fourteen dB in order to dos.step 36 dB. The brand new get back death of plasma antenna even offers high well worth may include – dB to – dB. The better the prices of plasma volume and collision volume, the greater return losings can be acquired https://sugardaddydates.net/sugar-daddies-canada/mississauga/. The costs obtained is actually relative to your traditional types of metal antenna.
113 Thermal Conductivity off Al2O3/Water-Depending Nanofluids: Revisiting the fresh new Influences out of pH and you can Surfactant
The present work focuses on the preparation and the stabilization of Al2O3-water based nanofluids. Though they have been widely considered in the past, to the best of our knowledge, there is no clear consensus about a proper way to prepare and stabilize them by the appropriate surfactant. In this paper, a careful experimental investigation is performed to quantify the combined influence of pH and the surfactant on the stability of Al2O3-water based nanofluids. Two volume concentrations of nanoparticles and three nanoparticle sizes have been considered. The good preparation and stability of these nanofluids are evaluated through thermal conductivity measurements. The results show that the optimum value for the thermal conductivity is obtained mainly by controlling the pH of the mixture and surfactants are not necessary to stabilize the solution.
