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 Interactions ranging from Spatial Design and you can House Speed
Belongings rate has the full services regarding metropolitan room, representing the newest societal and economic top features of the city. Consequently, property price can be used while the an indicator, which can choose the changes out-of spatial design and you may socioeconomic variations as a result of metropolitan advancement. This study tried to talk about the alterations from inside the land speed because of the a new street framework. Methodologically, they then followed Area Syntax, that will interpret metropolitan spatial structure totally, to identify the partnership between the types of street channels and land price. The result of the newest regression analysis demonstrated the latest ‘consolidation directory from Room Sentence structure try statistically high features good solid correlation which have residential property rates. In case your combination worthy of is actually highest, house rate expands proportionally. Next, playing with regression picture, they tried to assume the newest home speed change of each and every out of this new tons related the newest channels that will be newly opened. 
The research measures or study show feel the advantage of predicting the changes inside the homes rate in the an easy way. As well, it can sign up for coordinators and you can investment professionals to determine associated polices and you can smoothing metropolitan regeneration tactics through enhancing owners skills of the bringing you’ll be able to performance and you will masters in their house rate till the performance out-of metropolitan regeneration and you may invention projects.
114 Plasma Features Influence on Neon Tube Plasma Antenna Abilities
That it papers merchandise the research for the results out of monopole antenna with neon tubes. Within this look, new simulator and you may fresh means is carried out. The fresh neon pipe with assorted length and dimensions are designed using Computers Simulation Technology (CST) app together with attributes out-of antenna factor is actually artificial on app. CST was utilized so you’re able to replicate antenna parameters such as return losings, resonant frequency, obtain and directivity. Vector Community Analyzer (VNA) was used determine this new go back loss of plasma antenna in acquisition so you can validate this new simulation efficiency. Throughout the simulator and you may test, the production volume is decided ranging from step 1 Ghz in order to 10 Gigahertz. The outcome show that the newest come back death of plasma antenna alter whenever measurements of fluorescent tubes is actually ranged, correspond to the different plasma features. They means that more thinking regarding plasma attributes such plasma frequency and you will collision regularity gives distinction results of come back loss, obtain and you may directivity. Into the acquire, the costs cover anything from dos.14 dB to 2.thirty six dB. New return death of plasma antenna has the benefit of higher worthy of include – dB to – dB. The greater the costs from plasma frequency and you will collision frequency, the higher get back loss can be found. The prices gotten try comparative for the traditional type of metal antenna.
113 Thermal Conductivity off Al2O3/Water-Situated Nanofluids: Revisiting the brand new Has an effect on 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 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.
