1 e-magazine MECHANICAL DEPARTMENT 2 ND EDITION 1

2 PREFACE The e-magazine is a quarterly magazine published by the mechanical department. In this edition poems from students, research papers from the faculty and articles on latest technological advancement are included. In addition to it magazine also provides space for the inclusion of various technical and cultural activities happened in the department during past four months. The previous edition of this magazine was first initiative of the department towards publishing of department activities in electronic form and hence some typing /miscellaneous errors remained. This edition was far more crucially scrutinized and checked by some of the best faculties not of this department but also from through the college. Hope this magazine becomes the reflection of mechanical department and will cater all the needs of readers. Thank you! Sidharth Gandhi AP Mechanical Department 2

4 RESEARCH PAPER An efficient Genetic Algorithm Approach for Minimising the Makespan of Job Shop Scheduling Problems 1 Pardeep Kumar, 2 Pawan Kumar, 3Ram Bhool, 4Virender Upneja 1,2,3,4 Assistant Professor, Panipat Institute of Engineering and Technology, Samalkha, Panipat, Haryana, India Results and Discussion Two different problems based on Job Shop Scheduling (JSS) are taken with different operating parameters [refer to table 3.1]. A modified GA is then proposed to optimize the make span by taking new operating parameters. In order to verify the validity of proposed algorithm, a computer programme using MATLAB is developed and run for seven different problems with their operating parameters which gives the same value of make span. The new operating parameters to solve the JSSP are given as: Abstract The Job-Shop Scheduling Problem (JSSP) is a schedule planning for low volume systems with many variations in requirements. In Job-Shop Scheduling Problem (JSSP), there are k operations and n jobs to be processed on m machines with a certain objective function to be minimized i.e. makespan. In this dissertation, a promising genetic algorithm for the job-shop scheduling problems is proposed with new operating parameters i.e., a random population generation with a population size of 50, operation based chromosome structure, tournament selection as selection scheme, 2-point random crossover with probability 80% (Pc = 0.8), 2-point mutation with probability 20% (Pm = 0.2), elitism, repairing of chromosomes and no. of iteration is An algorithm is programmed for JSSP using MATLAB 2009 a 7.8 and seven different bench mark problems are tested with their operating parameters for makespan which also validates the computer codes developed. The Genetic Algorithm (GA) with new operating parameters is then applied to the same problems. The results show that it gives better value of make span for the given problems. The results also show that the Genetic Algorithm is the best optimization technique for solving the scheduling problems due to its implications to more practical and integrated problems. The application of Genetic Algorithm (GA) with new operating parameters to two different problems gives an improvement in the make span as illustrated 4

5 ARTICLE Colloidal Quantum Dots-A New Material For PV CELL By: Er.Vishal Dabra, Asst Professor (Mechanical Department) Engineers have worked for ways to enhance the performance and cost-effectiveness of solar cell. A solar PV cell array is comprised of hundreds, sometimes thousands of solar cells, that separately convert radiant sun light into electrical energy. The average solar PV cell is approximately 15% efficient, which means nearly 85% of the sunlight that hits them does not get converted into electrical energy. As such, engineers have constantly been experimenting with novel technologies to enhance this radiant sunlight capture and conversion. is a unique research since previous designs weren't capable of functioning outdoors and therefore not practical applications for the solar market. This helps increase radiant light absorption. PV cell using this novel technology were found to be up to 8% more efficient at converting sunlight. Colloidal quantum dots irradiated with a UV light Recently, at Toronto a group of reseachers of university unveiled a new type of light-sensitive nanoparticle called colloidal quantum dots, that many believe will offer a less expensive and more flexible material for solar cells. Specifically, the novel materials use n-type and p-type semiconductors - but ones that can actually function outdoors. This Ideallized image of colloidal nanoparticle of lead sulphide 5
