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 fresh new Connections anywhere between Spatial Construction and you may Homes Rates
Home rates contains the total functions out-of metropolitan place, representing the fresh public and you will financial options that come with the city. Consequently, home rate may be used as the an indication, that may pick the changes regarding spatial structure and socioeconomic differences due to urban development. This study made an effort to explore the changes inside belongings price by the a special highway structure. Methodologically, they then followed Room Sentence structure, that can understand urban spatial construction totally, to recognize the relationship amongst the different road companies and you will homes rate. The result of the fresh new regression analysis shown new ‘consolidation list away from Area Syntax is mathematically extreme and also an excellent solid correlation with home speed. If the combination worthy of was high, belongings rate grows proportionally. Next, playing with regression picture, they made an effort to anticipate the latest belongings price transform of each and every out-of the latest lots nearby the latest paths that are recently unsealed. The study methods otherwise research show have the advantageous asset of predicting the changes into the property price when you look at the a good way. While doing so, it does subscribe to planners and you may enterprise executives to establish relevant polices and you may smoothing urban regeneration ideas due to increasing citizens expertise by providing you’ll show and benefits inside their homes speed until the execution away from metropolitan regeneration and advancement systems.
114 Plasma Properties Effect on Fluorescent Tube Plasma Antenna Overall performance
This report gift suggestions the study for the performance out-of monopole antenna with neon tubes. Within browse, the new simulator and you can fresh approach is conducted. The newest neon tubing with various duration and you will dimensions are designed using Desktop Simulation Technical (CST) software and also the features out of antenna factor is actually artificial throughout the software. CST was used to help you simulate antenna variables like get back losings, resonant volume, acquire and you may directivity. Vector Circle Analyzer (VNA) was applied determine the new go back death of plasma antenna in order to help you verify new simulator performance. Throughout the simulator and test, the production frequency is decided starting from step 1 Ghz in order to ten Ghz. The outcomes demonstrate that the newest come back death of plasma antenna transform when sized neon tubes is ranged, match the many plasma features. It shows that different beliefs out-of plasma services for example plasma frequency and you may accident volume gets differences outcome of get back losings, obtain and directivity. To the gain, the values start from 2.fourteen dB so you can dos.step 36 dB. The go back loss of plasma antenna also offers high worth range between — dB to — dB. The greater the costs off plasma frequency and you can crash regularity, the greater return losings is available. The values acquired is comparative on antique style of steel antenna.
113 Thermal Conductivity away from Al2O3/Water-Oriented Nanofluids: Revisiting the fresh new Influences out-of pH and 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 https://datingranking.net/sugar-daddies-usa/wi/milwaukee/ 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.
