Automatic Solar Tracking System

Solar energy is very important means of expanding renewable energy resources. In this paper is described the design and construction of a microcontroller based solar panel tracking system. Solar is a nonconventional source of energy, considering this we have developed solar panels so that we can fulfill our electricity need. But due to revolution of the earth, solar source i.e. sun does not face the panel continuously hence less electricity is produced. The energy panel should face the SUN till it is present in a day. The problem above can be solved by our system by automatic tracking the solar energy. The block diagram below shows system architecture it consist of a LDR sensor senses max solar power which is being given to the Microcontroller through the ADC which digitizes the LDR output. Controller then takes the decision according to then algorithm and tilts the panel towards the direction of the max energy given by LDR with the help of DC Motor . The Motor is used to rotate the LDR to sense the max solar power. A Solar Tracker is basically a device onto which solar panels are fitted which tracks the motion of the sun across the sky ensuring that the maximum amount of sunlight strikes the panels throughout the day. After finding the sunlight, the trackerwill try to navigate through the path ensuring the best sunlight is detected. It is completely automatic and keeps the panel in front of sun until that is visible. Its active sensors constantly monitor the sunlight and rotate the panel towards the direction where the intensity of sunlight is maximum. Residential that uses solar power as their alternative power supply will bring benefits to them. The main objective of this project is to development of an automatic solar tracking system whereby the system will caused solar panels will keep aligned with the Sunlight in order to maximize in harvesting solar power. The system focuses on the controller design whereby it will caused the system is able to tracks the maximum intensity of Sunlight is hit. When the intensity of Sunlight is decreasing, this system automatically changes its direction to get maximum intensity of Sunlight. LDR light detector acts as a sensor is used to trace the coordinate of the Sunlight by detecting brightness level of Sunlight. While to rotate the appropriate position of the panel, a DCgeared motor is used. The system is controlled by two relays as a DC geared motor driver and a microcontroller as a main processor. This project is covered for a single axis and is designed for low power and residential usage applications. From the hardware testing, the system is able to track and follow the Sunlight intensity in order to get maximum solar power at the output regardless motor speed.

The Impact of Temperature and Relative Humidity Elevation on Mental Health of In Patient Admitted Into Jos Teaching Hospital Jos, Plateau State, Nigeria

The paper examined the impact of temperature and relative humidity escalation on mental health of in patient admitted into Jos Teaching Hospital JUTH Jos, Plateau State, Nigeria. The main independent variables of interest were temperature and relative humidity we also employed two derived parameters heat index and overlapping effect in our analysis in which we used four years 2011 2014 data of psychiatric cases and in patient that were admitted in the hospital, ex post facto research design was adopted for the study. The population of the study comprised 2073 in patient that was admitted in the hospital from the year 2011 2014 was sample used for the study. Data collected were analyzed with used of single regression and multiple regression analysis with complex heat index formula. The study found climate parameters temperature and relative humidity and their counterpart derived parameters heat index and overlapping effect make population vulnerable to the risk of psychiatric cases and do increase the numbers of patient admitted in the JUTH. There were positive association between the numbers of in patient in the JUTH and those parameters with 41 and 38 critical acute psychiatric cases due to overlapping and heat index effect respectively. In other word 79 10.2 of the total 778 numbers of patient traceable to those parameters were in critical acute psychiatric condition. Increase in the relative humidity and overlapping made population more vulnerable to the risk of psychiatric cases with approximately equal strength than the heat index and temperature. But the heat index makes more risk than temperature. The vulnerability of population to psychiatric cases was not equally distributed throughout the year 2011 2014. Population response differently to the impact of each parameter throughout those years considered. The effective strength of relative humidity determines the effective strength of the overlapping effect and the effective strength of temperature determine that of the heat index.

Research Paper on Digital Notice Board

Digital Notice Board is primary thing in any organization, institution or public utility places like bus stop, railway stations, schools, colleges, malls, etc. But sticking multiple notices every day is a hard process. An individual person is needed to take care of these notices. This project is about advanced wireless notice board. The project is built around raspberry pi. Display is obtained on LCD. A wireless fidelity is used for Data transmission. we can add or erase or differ the text according to our need. At transmitter, authorized PC is used for sending notices. At receiving end wireless fidelity is connected to raspberry pi. When an authorized user sends a message that is to be displayed from his system, it is accepted by receiver. Wireless is a popular technology that allows an electronic device to exchange data over a computer network, including high speed wireless connections. The data is received from authenticated user, then it sends the data to raspberry pi.

Study on Overhead Circular Water Tank using with and with Out Center Column by Staad Pro V8I

"Elevated water tanks models are designed using STAAD Pro. The columns are taken circular for both tanks and diameter are 300 mm and height is 15 meter. The height of water tank is 4.3 meter and diameter is 8 meter for circular water tanks. Capacity of water stored is 200KL or 200000 liter. These models are analyzed for dead load, water load and seismic load. Dead load was designed according to IS 875 1987 Part 1 and Seismic load was designed using response spectrum method for earthquake zone III of India using IS 1903 2002. For analyzing a elevated water tank one has to consider all the possible loadings and see that the structure is safe against all possible loading conditions. Capacity of the water tank is considered 200000 L. There are several methods for analysis of different frames like finite element method. Two tanks are design for 200KL capacity in circular tank without center column and circular tank with center column. The height is kept same for both water tanks that is 21 m from ground level.

Design and Modelling of a Leaf Spring using 3D Printing Technology

3D printing technology forms the basis of corporation's prototyping process. 3D printing technology creates 3D physical protypes by solidifying layers of deposited power by using a liquid binder. 3D printing is an versatile process accommodating geometry of varying complexity in hundreds of different applications, and supporting many types of materials. By eliminating production steps and using substantially less material, additive process could be able to reduce waste and save more than 50 of energy compared to today's subtractive manufacturing process and reduce material cost upto 90 .The use of additive manufacturing can potentially benefit a wide range of industries including defence, aerospace, automotive, biomedical, consumer products and metal manufacturing. A leaf spring is a simple form of spring, normally used for the suspension in wheeled cars. Leaf springs are long and narrow plates attached to the body of a trailer that rests above or under trailer's axle. For safe and cozy using, to prevent the street shocks from being transmitted to the car components and to guard the guard the occupants from the road shocks it's miles important to determine the maximum safe strain and deflection. The objective is to find the stresses and deformation in the leaf spring via making use of static load on it. One of a kind of special materials with mechanical properties are taken into consideration for the structural static evaluation. All leaf spring has linear characteristics there is a linear dependence between force and deflection this means that the 3D printed springs could be used as machine elements in different applications.
