GSM based Door Access Security System has principle application in security frameworks and it can be utilized as a part of Industries, Shops, Offices and in our homes. It replaces the customary security frameworks which utilizes key to open entryway. This venture has keyless passage to the entryway. Client needs to send secret key through SMS utilizing his/her portable. In the event that the secret key is right then Microcontroller turns on a DC engine and a Relay. Bell is turned on for wrong secret key. In its most straightforward shape Home security is the capacity to control entryway open or close Family security remotely. The transmitter depends on remote GSM strategy the idea Door bolting and opening System utilizes GPRS to open and close the entryway. Not with standing this security will be given utilizing GSM in the event of any unapproved get to. DC engine will then perform activity on entryway either bolting or opening.

Education paves way to sustain human life. Its chief focus is to teach the human values, develop Education paves way to sustain human life. Its chief focus is to teach the human values, developintellect, emotions, empathy, extricate opportunities to rise to the occasion and contribute to theoverall growth of the society. Ultimately this should provide an individual, an all-round developmentt o observe, understand and to be a part of the larger community. This education is obtained formally, non-formally and informally. Informal learning occursin a variety ofplaces, such as athome, work and through daily interactions and shared relationships among members of society. For many learners, this includes language acquisition, cultural medians and manners. Formal learningis commonly divided into different stages such as Pre-School, Elementary School, High School, Higher Secondary School and then College/University orApprenticeship through various industries.The School Education systemin India has 4 distinct levels such as Lower Primary (ages 6-10) Upper Primary (age 11 & 12) High (13 – 15) and Higher Secondary (17 &18). Then we have the Tertiary Education which is the threshold to employment. This Tertiary level includes 3 years of Under Graduation and 2 years of Post-Graduation and then Research Activities which are optional. All these lay foundation to one’s career for sustenance or “Survival of the Fittest” as told by theAll these lay foundation to one’s career for sustenance or “Survival of the Fittest” as told by the English Naturalist Charles Darwin (1809-1882) in his Origin of Species Theory. The college-level focused education in due course determines the career prospects of the young graduates. After 1990s there is a paradigmatic shift in the employment in India, that instead of the candidates running helter-skelter for employment, the employers knock at the door of Higher Institutions. Campus Interviews bridge the gap between the Employers and the prospective Employees. In ourcontext, the final year UG/PG students are the Prospective Employees who are eligible for Campus Interviews. Campus Interviews offer final year UG/PG students a great opportunity to get a suit-able job during the course of their academic pursuits and provide them a secure future before the completion of their course itself. This process includes the various stages such as: Pre-Placement Talk, Aptitude Test, Technical Test, Group Discussion, HR Interview and Personal Interviews. This paper purports the role of various Employing Agencies who consistently contact the colleges/Universities through Campus Interviews to select their prospective employees. Also it brings tolimelight the various top notch companies in Chennai which absorb the creamy layer among theeligible students.

In current days, fuel stations are worked physically. These fuel pumps are tedious and require more labor. To put fuel stations in removed zone it expensive to give brilliant office to the purchasers all these issue are dealt with by the utilization of unmanned oil pump which requires less time to work and it is viable and can be introduced anyplace the client self-going to benefit the administrations the installment is finished by electron-ic clearing framework. The straightforward and legitimate utilization of microcontroller and GSM innovation gives an aggregate security and atomization in the conveyance of fuel. It has simple worked cell phone framework and client interface (GUI). It interfaces with rapid fuel gadget, which is advantageous for the purchaser to work. In our framework the watchword will be given to the client and client needs to enter this secret key on the LCD gave by the fuel station which will enable the oil to organization to make confirmation for the client additionally the dispersion of the fuel isn't conceivable until the point when it gets confirmed by the database. To put it plainly, we give a protected framework to fuel dissemination. The headway of this task can help industry monetarily.

Refrigerator is a household appliance used to preserve the foods, vegetables, beverages at low temperature. Refrigerant is the blood of the refrigerator and it changes its phase to transfer heat for giving cooling effect inside the refrigerator. Generally many refrigerator works under the vapour compression cycle and it uses only one refrigerant. Each and every refrigerant used in the refrigerator must have disadvantages, to overcome this problem we use mixed refrigerant (two different refrigerants with different properties are mixed together). In this project combination of R600a (isobutane) and R134a (1, 1, 1, 2-tetrafluroethane) is selected as a mixed refrigerant. R600a have some good properties like zero ODP, zero GWP and high latent heat of vapourization and R134a is non-toxic, non-flammable, non-corrosive and zero ODP.
