Design and Fabrication of Solar Powered Mobile Cold Room

The Design and Fabrication of Solar Powered Mobile Cold Room is a refrigeration system that uses solar energy. It was embarked upon as a result of the epileptic power supply to the rural areas in the country and the absence of a grid supply to some locations where needed. The mobile cold comprises of the following components, the D.C compressor Danfoss BD92K, charge controller 40A, 12V, solar battery 12V, 200AH, solar panel 12V, 600 watt and a 500 litres compartment. The power is not supplied either from the national grid nor the generator system, but from the solar panel. The solar mobile cold room comprises of the solar panel that collects the solar energy. The solar panels convert the solar energy into electrical energy and stored it in the battery. During the normal running of the cold room, the power is supplied directly by the solar panel, but when the output power of solar panels is less, the additional power is supplied by the battery. The battery is recharged when excess amount of power is produced by the solar panels. The output supply of the batteries and the solar panel is DC with voltage of about 12V. A microcontroller was used to display the inner temperature of the freezer and also to protect the compressor by switching it off when the door is opened for a period of 60 seconds. The charge controller is connected to the battery and solar panel to regulate the voltage from the solar panel for the charging of the battery, the supply from the battery is used in running the D.C compressor of the cold room in the absence of sunlight or when the sun intensity is low. The system is capable of running for 18 hours without the presence of sunlight when the battery is fully charged it also has a high storage capacity of 500 litres and longer operation time as compared to previous solar refrigerators.

Implementation of 5G in Guided and Unguided Optical Communication System with Cellular Frequency Bands

Optical wireless communication is the budding technology of fifth generation communication networking systems. It is an emerging platform to interconnect the domestic appliance together with a strong optical backbone network. However for a very long distance communication over 500 to 1000 km optical fiber is irreplaceable. The speed of the data communication is higher in free space optical communication without amplifying the received signal at the receiver side. The microwave optical communication frequency ranges from 3GHz to 30 GHz. Millimeter wave optical communication with 5G network is under progress. In this paper, the speed of communication used is 50 Gbps. The different channels optical wireless communication OWC , free space Optical communication FSO and optical wired cables are considered with 5G speed. The Quality factor and maximum distance of transmission with suitable transmitter power is achieved via respective channels. Helen Vedanayagi Anita.

ANN Model Based Calculation of Tensile of Friction Surfaced Tool Steel

Friction surface treatment is well established solid technology and is used for deposition, abrasion and corrosion protection coatings on rigid materials. This novel process has wide range of industrial applications, particularly in the field of reclamation and repair of damaged and worn engineering components. In this paper, present the prediction of tensile of friction surface treated tool steel using ANN for simulated results of friction surface treatment. This experiment was carried out to obtain tool steel coatings of low carbon steel parts by changing input process parameters such as friction pressure, rotational speed and welding speed. The simulation is performed by a 33 factor design that takes into account the maximum and minimum limits of the experimental work performed by the 23 factor design. Neural network structures, such as the Feed Forward Neural Network FFNN , were used to predict tensile tool steel sediments caused by friction.

Soil Stabilization by use of Chemical

This work presented to see the efficiency of nano technology used in terms of chemical named as Terrasil which acts as a modifier and improves the engineering properties of black cotton soil. In India, we see about 51.8 million hectors of land area is covered with black cotton soil which is an expansive soil. It is seen that black cotton soil is very hard when it is dry, and it loses its strength completely when it is wet. Expansive soils are problematic soils worldwide and create problems while constructing structures on it. To improve their properties various methods are adopted. These soils are removed completely or mixed with better quality material or mixed with various additives. This chemical called terrasil is tested by conducting various tests like Proctor test, free swelling test, etc. Soil samples are treated with different percentage of Terrasil 0.9 , 1.1 , and 1.3 . Terrasil gives improved results up to 40 increasing compressive strength of soil. It reduces the swelling property of soil from 60 to 42.

An Experimental Paper on Compressive Strength of Pervious Concrete

Pervious concrete has been in use in many countries over more than a century. Its higher porosity helps in percolating rain water directly to ground and thereby helps in recharging groundwater aquifer. In this study, pervious concrete of sizes of 6.3mm size aggregate were prepared with different water cement ratios to find the compressive strength. The purpose of this project is to analyze the feasibility of producing highly sustainable no fine concrete mixtures and evaluating the effect of W c ratio on the properties of pervious concrete. Porous concrete is produced by using ordinary Portland cement, coarse aggregates, and water. This concrete is tested for its property compressive strength. The results showed that the water cement ratio showed significant effect on compressive strength of Pervious concrete.

Some Physical Properties of Negro Pepper Seed Xylopia Aethiopica Necessary for Post Harvest Handling

Negro pepper is a spice with high nutritional value and several beneficial phytochemical compounds. Physical attributes of biomaterial are important in many problems associated with the design of machines and the analysis of the behavior of the product during agricultural processing operations such as handling, planting, harvesting, milling, threshing, cleaning, grading, sorting and drying. This study was aimed at determining some physical properties of Negro pepper seed xylopia aethiopica including axial dimensions, grain mass, bulk and true densities and porosity. Manual methods of measurements were employed in which the seeds were either measured directly or in bulk. Other parameters were calculated such as arithmetic, geometric mean diameter and sphericity. Seed weight and volumes were measured by using standard measuring equipment. All properties were determined at a fixed moisture content. The result of the study showed that the average length, width and thickness of the negro pepper seed were 5.99 0.42, 3.51 0.25 and 3.05 0.14mm respectively. Geometric mean diameter and sphericity of the Negro Pepper Seed were obtained as 3.80 0.13mm and 65.53. 0.11 respectively. The Solid density, Porosity and bulk density for negro pepper seeds were 0.56 0.25 g m3 49.50 0.22 and 1.125 0.31 g m3 respectively all measurement were obtained at a seed moisture content of 37.5 wet basis.

A Study of Wheat Flour Tortillas using Laser Induced Breakdown Spectroscopy LIBS

Wheat flour tortillas of different colors and composition were studied with the aid of laser induced breakdown spectroscopy LIBS. Due to its simplicity, fast response, little or no sample preparation, LIBS is presented as an effective tool for rapid in situ sample analysis of food samples with emphasis on tortillas. Spectroscopic analysis of the plasma generated by Nd YAG laser irradiation of tortilla was carried out. A careful selection of spectral lines of Ca, Na and K which do not suffer from spectral interference was made. Spectral properties of the above mentioned elements such as peak intensities, intensity ratios, and area under spectral lines were analyzed. Optimization of laser pulse energy, detection gate width and gate delay for well resolved spectra with high signal to noise ratio was done and other parameters studied. Among the spectral lines selected for analysis, the Na I 589.00 and 589.60 nm doublet were found to show interesting properties. Tortillas manufactured by Gruma Corporation and Mexamerica, of brown, orange, green and white colors as well as homemade tortillas were studied in this work and the results from both dried and undried samples is presented.
