It began with Thomas Newcomen (Dartmouth) in the early 1700's. Early developments were very slow and Newcomen's design was used in England for nearly 100 years. Newcomen's engine could be better described as a 'vacuum' engine. The vacuum was created by condensing steam. The engine however, was extremely inefficient, and where coal had to be brought from a distance it was expensive to run. James Watt (1769) brought about a major increase in power and efficiency with his developments. Watt redesigned the engine so that condensation occurred outside of the cylinder. This meant that the cylinder did not lose heat during each stroke. It also allowed the use of pressurized boilers thus obtaining power on the up-stroke as well as the down-stroke. The beam engine gave way to the reciprocating steam engine which was refined to a high degree. Double and triple expansion steam engines were common and there was scarcely a demand for mechanical energy which steam could not meet. However, reciprocating steam engines were complicated, and hence not always reliable. In 1884 Charles Parsons produced the first steam turbine. With Michael Faraday's earlier discovery of electromagnetic induction (1831) the widespread use of electricity had begun. The two technologies came together and with the National grid, progressively eliminated the need for factories to have their own steam plant. Today, mechanical power production using steam is almost wholly confined to electricity generation. 1.2 Objectives: Know boiler, steam turbine, and Describe cooling towers and condensers. Calculate the power output of a steam turbine power plant. 2. Theory: Steam cycles used in electrical power plants and in the production of shaft power in industry are based on the familiar Rankine cycle, studied briefly in most courses in thermodynamics.

Drilling is typically practiced in industries for component assembly In mechanical structures Drilling is one among the foremost frequently practiced machining processes and it's undoubtedly the fore most widely used machining operation. Drilling is perhaps the foremost important conventional machining process and it's undoubtedly the foremost widely used machining operations. Predictions of cutting forces for any set of cutting parameters are essential in optimal design and manufacturing of products. It's been predicted that the majority of the issues related to hole making operations, like drilling are often attributed to the force generated during cutting operation. Additionally, accurate estimation of forces helps in design and evaluation of cutting tools and fixtures. In this project we do drilling on Copper, Steel, and Aluminium. We are using 6 mm drilling bit for drilling the plates and therefore the rpm using during this project are 1800,1400,1120,500,710 and miller with Rpm is employed for drilling and also we are justify which rpm is employed for drilling the specify materials. Solid works software is employed for modelling the work pieces and gear (drill bit). Solid works is parametric software used for recent technologies. Solid works (COSMOS) is employed for doing analysis on the components. Structural, Modal and Thermal analysis are used for comparing the stresses and thermal flux values.

The PV arrays are connected to the point of common coupling (PCC) through a DC-DC boost converter, a DC-link capacitor, a grid side inverter, and a three-phase step up transformer. The DC-DC converter is used for a maximum power point tracking operation based on the fractional open circuit voltage method. The grid-sideInverter is utilized to control the DC-link voltage and terminal voltage at the PCC through a vector control scheme. The CMPN algorithm-based adaptive proportional-integral (PI) controller is used to control the power electronic circuits due to its very fast convergence. The proposed algorithm updates the PI controller gains online without the need to fine tune or optimize. For realistic responses, the PV power plant is connected to the IEEE 39-bus New England test system. The effectiveness of the proposed control strategy is compared with that obtained using Taguchi approach-based an optimal PI controller taking into account subjecting the system to symmetrical, unsymmetrical faults, and unsuccessful reclosing of circuit breakers due to the existence of permanent fault. The validity of adaptive control strategy is extensively verified by the simulation results, which are carried out using PSCAD/EMTDC software. With the proposed adaptivecontrolled PV power plants, the LVRT capability of such system can be improved.

Construction of highways involves huge outlay of investment. To satisfy the design requirements of stability and durability the bituminous mixes should be designed effectively. The ingredients of the mixture include dense grading of coarse aggregates, fine aggregates, fillers and bitumen binder. In this study an attempt was made to find the effect of filler on the behaviour of bituminous mixes. Filler plays an important role in the filling of voids and hence change the physical and chemical properties. An important role is played by the fillers that pass through 0.075mm sieve. Conventionally stone dust is used as filler. An attempt has been made in this investigation to assess the influence of non-conventional and cheap fillers such as brick dust and steel slag in bitumen paving mixes. The properties of bituminous mixes containing these fillers were studied and compared with each other. Various tests were also conducted on aggregates and bitumen and the results were compared with the specifications. The study revealed that use of brick dust and slag as fillers with 2%, 3.5%, 5%, and6.5% was used to improve the physical characteristics of bitumen mixes.

Unlike other solid state joining technique, in Friction stir welding a third body contact by tool will generate the additional interface surfaces and finally all the surfaces are coalesced with each other by applied pressure and temperature and form solid state weld. This work shows overview of Friction stir welding which includes the basic concept of the process, microstructure formation, influencing process parameters, typical defects in FSW process and some recent applications.

In this project the Bit error rate performance analysis is done by using 1X1, 1X2, 2X1 and for 2X2. And BER comparison is done for different modulation techniques like QPSK and QAM. Here the complexity for QPSK and QAM is more compared to BPSK. BPSK is the simple technique and less affected by noise. And the power required to transmit the data is also less compared to other techniques.
