Smart Solar System With Digitizer

In the past these where working on pure AC supply. The components used in these types of appliances were also AC. The limitation of AC supply was that it required more current then we used our project for example. LED scrolling display used 230Volt/35Amp (AC) before, whereas our project uses 5Volt/10Amp (DC).Now we are using solar power for working of these appliances. We are combining all three appliances on one source. It provides combined features where we can display the notice, streets can get light and there is facility to charge phone in emergency.In future we can add a network router to this combination. This will give free internet connection to rural areas with effective 500m working diameter. The display can be modifyingsuch a way that it receives order from voice messages

Analysis of Composite Beam by Finite Element Method

An analysis of the Composite beam placing emphasis on shear deformation effects is done by using beam theories and software ANSYS workbench. Results using two dimensional plate theories are presented to calculate stresses in the beams. Two dimensional plate theories are Classical laminated plate theory, first order Shear deformation theory, third order Shear deformation theory and Euler-Bernoulli theory. Unit axial load over the junction of two layers is placed and analyzed. For manual analysis transverse shear stresses are obtained directly from the use of constitutive relations with good accuracy. Principle of virtual work is used for obtaining boundary conditions and governing differential equations. A hollow circular composite beam is analyzed for two different aspect ratios. The concept that is used in this paper is that Graphite epoxy layer or laminate is sandwiched between two Steel layers or laminates, and all the properties of both the materials are taken into consideration wherever applicable

Review on Zipper Braced Frames

Now-a-days the structures are prominently build for the earthquake resistance so that it can resist the building strongly. The tectonic plate which are resembles for earthquake are more rapidly moving. Roughly now it is 15cm/year. To overcome the problem which arises from earthquake, the typical method of bracing is applied to withstand all forces and load. One of the bracing is zipper bracing frame, which increases the stiffness, strength and stability of the structure. This paper reviews the influence of zipper bracing system with other braces. The history of bracing system is visited, various braces are studied, their strength, mechanism, failure pattern, loading mechanism, overall stability were dissected. Proper and efficient structural bracing leads to the sustainable structures and economical buildings, which has high initial costs but low maintenance cost throughout future

Design and Implementation of Single Phase Inverter

Now a days due to industrialization, there is gap between demand and supply, therefore the need of electricity is increased and we use the electricity efficiently. We cannot store the electricity in AC form, so we store the energy in battery in the form of DC and then it converts into AC using inverter. In that project, we are design and implement the inverter bridge on single phase full and half bridge inverter with R and RL load In that project the PWM method can be used for the generation of the waveforms
