Transesterification of Waste Cotton Cooking Oil was reported. Different catalysts were studied. A maximum yield of 92% was reported for calcined eggshells catalyst. KOH and pistachio shell reported 91% and 84% respectively. The temperature, reaction time and catalyst loading were optimized to be 60°C, 60 min and 3% (wt.%) respectively for egg shell and pistachio shells. The methanol to oil molar ratio suitable molar for transesterification catalyzed by calcined eggshell was 9:1 and 12:1 for pistachio shell. By using low cost catalysts from waste resources such as eggshell and pistachio shell for biodiesel from waste cotton cooking oil gives higher yield of production. It seems to be relatively easy to separate up to higher production of biodiesel, time saving, energy efficient and eco-friendly.

In this Work, the Distributed Energy Resources (DERs) are used in a specific small area which is known a microgrid. Microgrid consists of microsources like distribution generator, solar and wind units, etc., and different loads. In the microgrid, the energy management system (EMS) having a problem of Combined Economic Emission Dispatch (CEED) and it is optimized by meta-heuristic techniques. The CEED is the procedure to scheduling the generating units within their bounds together with minimizing the fuel cost and emission values. The JAYA Algorithm is applied for the solution of CEED problem in the MATLAB environment. The minimization of total cost and total emission are obtained for all sources included. The result shows the comparison of JAYA Algorithm with the Gradient Method (GM), Ant Colony Optimization (ACO) and Particle Swarm Optimizer (PSO) technique for the two different cases which are Economic Load Dispatch (ELD) without emission and with emission. The results are calculated for different power demand of 24 hours. The results obtained with JAYA Algorithm gives comparative better cost reduction as compared to GM, ACO and PSO which shows the effectiveness of the given algorithm. The key objective of this work is to solve the CEED problem to obtained optimal system cost.

Robot's uses are increasing in areas such as food, consumer goods, wood, plastics and electronics. But still most researches have involved in the Agriculture industry. The aim of this new work is to develop prototype of areca tree with conceptual design. The robot motions from Areca tree is controlled by separate motors. However, the concept of three individual motor is representing a part of the prototype and its design is evaluated. The wrist also needs to be constructed in the top of the robot which is used for cutting the Areca nut. Thorough analysis has been made to recommend that a mechanical prototype is made to test the movements of the robot. The concept of designing lightweight materials is realized by using the newly developed prototype with the design that is resulted from the implemented design process. Hence, that the robot is used for agricultural industry in future.

The efforts of man to integrate daylight in the interior of any building had its start during the ancient civilizations. Despite of reducing the energy consumption due to artificial lighting to a considerable extend, daylight integration has positive effects on the health and productivity of its inhabitants. The building design and its climate are the major factors that determine the amount of daylight penetrating in to the interior of the building. This paper aims to analyze the daylight availability in the interior of a building, with a fixed design and orientation, for different climate zones of India. The building is modeled in Ecotect daylighting tool and simulated using Radiance Beta V2.0. Illuminance is considered as the performance indicator in this study. The percentage of daylit area for all the climate zones of India for the equinox day is presented in this paper. Comparison of optimally daylit area, under illuminated, over illuminated and glare perceived area is also presented for the cities of different climate zones.

A wider band gap (2.3eV) material In0.5(Al0.7Ga0.3)0.5P based BSF layer lattice matched with both top In0.49Ga0.51P and bottom GaAs cell is found to increase 6% more efficiency than other widely used Al0.7Ga0.3As material under the same cell configuration because of its high photo generation rate. A numerical simulation analysis of these BSF layer in InGaP/GaAs dual-junction solar cell is investigated using TCAD tool Silvaco ATLAS. The cell is modeled using these two BSF materials both for top and bottom cells and compared all their performance parameters. InAlGaP is found to be a better choice for both window and BSF layer. The cell efficiency and EQE is further optimized by varying BSF layer thickness under current matching condition which is achieved with relatively thinner BSF layer of top cell (30nm) and the thicker BSF layer of bottom cell (1000nm). For this optimized cell structure, a maximum conversion efficiency of 36.67 % (1000 suns) are obtained under AM1.5G illumination. The detail photogeneration rates in this optimized DJ solar cell structure with DLAR of Al2O3-TiO2 are also generated and compared.

The characteristic of the photovoltaic system (PV) varies with time to time based on solar irradiation and whether condition. However, the Maximum Power can be extracted from the PV system with the help of Maximum Power Point Tracking (MPPT) techniques. In this paper, a Perturb and Observe (P & O) algorithm is used to obtain the maximum power by the procedure of perturbing and observation. To avoid the ripple content present in the solar cell array (SCA) current a Coupled Inductor SEPIC converter is proposed here based on governing circumstance of the ripple. Moreover, the efficiency of the converter is improved by using coupled inductor because it needs only lesser amount of magnetic core. So the P & O algorithm changes the duty cycle of the converter switch to cope with the load equivalent to the Maximum Power. It is achieved by MPPT algorithm, and it is determines the changes in converter duty cycle. In this invention, Mathematical models are defined and P & O algorithm is progressed. Then the PV system incorporated with MPPT controller modeling is invented in the SIMULINK.

Now a days, the need for increased indoor comfort together with the reduction of energy consumption in buildings are vital factors. Envelope systems and their influence on HVAC & lighting systems are playing a very important role in this. The improvement of the thermal comfort, the visual comfort and the buildings ventilation equipped with high glazing surfaces, generates significant energy savings. Solar Radiation will cause major role in increasing cooling load inside the buildings. In order to eliminate this problem Double Skin Facades and their shading devices was introduced. A double skin façade consists of a double glazing separated by a ventilated air space with two openings at the top and bottom of the façade equipped with internal shading devices. This paper aims that CFD modeling of Double Skin Facades and influence of shading devices inside the cavity. Air flow and heat transfer through the Double Skin Facade was also studied. The flow inside the cavity naturally ventilated and low turbulent flow is considered. Radiation model used in this study is Discrete Ordinate Model in FLUENT software. The variation of heat transfer with different emissivity, air flow rates is studied in energy savings point of view. The parameters which influence flow inside the cavity such as temperature, velocity, slat angles etc is analyzed and variation is noted.

Heat dissipation is a drastic issue to handle due to continued integration, miniaturization, compacting and lightening of equipment. Heat dissipaters are not only chosen for their thermal performance; but also for other design parameters that includes weight, cost and reliability, depending on application. Present study has been taken place with circular perforated fin array with different perforation diameter. The main objective of this paper is the Numerical study to quantify Natural Convection heat transfer enhancement of fins array with different types of perforations like Circular, Elliptical, Square and Triangular based on its performance as well as with saving in material by mass. The variables for this natural convection cooling with the help of finned surfaces are geometrical parameters and positioning of perforation. In this study, the steady state heat transfer from the solid fin and perforated fin arrays are compared. The optimized parameters are analysed for better heat transfer coefficient. The increase in the heat transfer coefficient was achieved with perforated fins for area corresponding to 12mm perforation diameter, which shows better enhanced heat transfer coefficient as opposed to the solid fin array with saving in material by mass.

Piezoresistive pressure sensor is a significant transduction mechanism for measuring pressure due to the fact that it is simpler to integrate with electronics, its response is more linear, they are inherently shielded from RF noise and fabrication is easy compared to other transduction mechanism. In this paper, piezoresistive transduction mechanism is employed for design of a pressure sensor. The diaphragm of the proposed sensor is designed using n-type Silicon with p-type Silicon piezoresistors placed on the surface of a diaphragm in a Wheatstone bridge configuration at the most sensitive region of the diaphragm. The proposed design is analyzed to study the deflection of the diaphragm and the output voltage across the bridge. The effect of change in piezoresistor length on the output voltage is also investigated. The results reveal that the proposed sensor provides highest sensitivity for the piezoresistor length of 50um.
