The load losses in the transformer consist of I 2 R & stray losses. In large rating transformer, the stray losses constitute about 20-25% of the total load losses. Designers adopt various cost-effective measures to minimize the losses and make the transformer more efficient. This Stray Losses we can reduce by using Ed…
The present investigation was mainly focus on the influence of high density polyurethane foam core on the flexural behavior of sandwich beams. To rate the performance of these structures, many engineering parameters such as face sheet stress (σf), core shear (τ) beam deflection(y) and the most important beam propertie…
Eu 3+ doped CaAl2B2O7 phosphors were prepared by the solution combustion synthesis technique. The doping content of Eu3+ ions in CaAl2B2O7:Eu 3+ phosphors are 0.1%, 0.2%, 0.5%, 1%, 2% (molar fraction), respectively. The structures and formation of the phosphors were characterized by XRD. Luminescence properties were a…
The effects of refraction (phase-contrast) are normally considered as disturbances in high-resolution µCT-measurements. We show that in the case of small objects with low absorption a single-distance phase-retrieval algorithm not only reduces the edge enhancement, but also raises the signal-to-noise ratio sufficiently…
This paper describes different power quality problems in distribution systems. And solution with hybrid filter configuration to suppress harmonic current distortion in the source current. This Hybrid filter is controlled by using the Mamdani inference method of Fuzzy Controller. This HSAPF are described showing their…
Fuzzy logic is an optomisation technique used to predict the Behaviour of any problem. In this paper an experiment was conducted on composite Polytetrafluroethylene filled with 25% carbon material on pin-on-disk machine to find out wear parameters. In this study, the effects of varying load, sliding distance and slidi…
Extensive studies have been made on the synthesis and crystal growth of nonlinear optical (NLO) materials over the past decade because of their pot ential applications in the field of telecommunicati ons, optical signal processing, and optical switching. Glycine L ithium Sulphate(GLS), a nonlinear optical material, wa…
Methane and carbon dioxide are the major \ncomponents of biogas produced by anaerobic digestion of \nbiomass and conversion of biogas to syngas is of great interesting \nfor making use of the sustainable biomass resource. The present \npaper deals with catalyst development and testing for the dry \nreforming of methan…
Carbon steels are widely used in petroleum industry. Examples of their extensive usage are pipelines, tubing, casings and a variety of other installations. Their widespread usage is essentially due to their advantages in terms of cost effectiveness. The efficiency of two commercial corrosion inhibitors named product A…
Austenitic stainless steels are engineering materials which contain 18% Cr-8% Ni. Due to their striking blend of excellent mechanical properties, formability, and corrosion resistance.They find wide range of applications in industries, namely chemical industries and beverage manufacturing. In this study the effect of…
The brightness of a photoelectron injector is fundamentally limited by the mean longitudinal and transverse energy distributions of the photoelectrons emitted from its photocathode, and the electron beam brightness is increased significantly if the mean values of these quantities are reduced. ASTeC have commissioned a…
Concrete is the world’s most versatile, durable and very reliable material. Geopolymer concrete is an innovative construction material which is produced by the chemical action of inorganic molecules. Fly ash is a by-product of coal obtained from the thermal power plant and it is available in plenty worldwide . Fly ash…
The initiation and development of damage such as cracks in an engineering structure under dynamic loadings is a typical nonlinear process. Strictly speaking, the conventional vibration and eigenvalues extraction based damage identification approaches are suitable for linear systems only. In this paper, based on a doub…
Structural and luminescence properties of borophosphate glasses with different modifier doped with transition metal ions have been investigated in this study. The glass sample from the series of xPb 3 O 4 :0.2Sb 2 O 3 :0.3B 2 O 3 :(0.5-x)P 2 O 5 and ySb 2 O 3 :0.2Pb 3 O 4 :(0.5-y)B 2 O 3 :0.3P 2 O 5 where 0≤ x ≤0.20 m…
Abstract— The Alum material was grinded for different times to display the spectrum of natural light and laser diode. The dimensions of the bodies were measured by scanner (easy scan microscope). A relationship was found between the change of particle nano size and the radiation intensity of light. These empirical r…
In this work we used DFT B3LYP/6-31G*(d) to study the stoichiometric reaction between the β-himachalene and dichlorocarbene. We have shown that β-himachalene behaves as a nucleophile, while dichlorocarbene behaves as an electrophile; and that β-himachalene reacts with an equivalent quantity of dichlorocarbene to produ…
Cadmium sulphide (CdS) nanocrystals with Cd:S molar ratio of 0.2:0.2, 0.3:0.3, 0.4:0.4, 0.5:0.5 M are synthesized by chemical coprecipitation method using poly vinyl alcohol (PVA) as capping agent. Crystallite sizes of CdS nanocrystals are determined from XRD analysis. The crystallite sizes are found to be 3.34, 3.54,…
Abstract- In this work, the extract of Allium Sativum was examined as a green corrosion inhibitor for zinc in 0.5N H2SO4 by using weight loss, gasometric and thermometric methods. Results indicated that the extract of Allium Sativum performed as a very good corrosion inhibitor for the corrosion of zinc. The inhibition…
