The role of social media on recruitment
Mohamed Azeem Ali M, A.Thiruchelvi
The process of recruitment in Human resource management has evolved greatly over the past few decades. With the invention of internet and development of web based channel, recruitment process has taken a new face called “E-Recruitment”. E-recruitment came with lot of advantages like generating large applicant pool, mass mailing, etc. Currently, majority of the profiles are sourced through job portals. In recent times, these job portals have developed complexity in recruitment process such us generating large but less reliable applicant pool, high subscription fee for the employers, delayed response, etc. In order to overcome these drawback, a new recruitment system is proposed by integrating social media (like LinkedIn, Facebook, twitter, etc.) and recruitment process. With the effectiveness and the power of social media, recruitment can be made more effective in terms of number of positions closed and time taken for closing an open position.

V.Sivanesan, C.Christober Asir Rajan
This study proposes a single-phase, 9-level, multilevel inverter (MLI) topology. The multicarrier, Phase Disposition (PD) Pulse Width Modulation (PWM) scheme is employed to generate the gating signals for the power switches. By controlling the modulation index, the desired number of levels: 3, 5, 7 and 9 of the inverter’s output voltage can be achieved. For modulation index of: 0.2, 0.4, 0.6 and 0.8, the proposed inverter configuration was subjected to an R–L load and the respective numbers of output voltage level were synthesized. The topology is self-voltage balanced across the series connected capacitors. The proposed approach helps in reducing the number of independent dc voltage sources. Also the harmonic content in the output voltage is very less when compared with conventional topologies. For a modulation index of 0.8, a Total Harmonic Distortion value of 14.03% has been achieved and adequate results are presented.

Nirmala Devi.V, Kumaresan.N
Monitoring and controlling the agriculture field parameters plays an important role in crop production and management. In many areas water is wasted while watering plants. At present there is scarcity water and we should know how to use the available water in an efficient way. Plants are immobile and some of the environmental conditions such as soil water content, air temperature and soil temperature affect the soil quality and thus the crop yield. High level sensing systems are needed to optimize the water usage and reduce spreading of diseases. Storage of information and its processing and management makes precision agriculture more efficient. IoT based sensing systems have improved capabilities to accurately monitor the environmental conditions. Automatic irrigation is the best way to optimize the usage of water in crops. In addition, gateway is also used control the sensor values and transmits these values to a user. The gateway is programmed based on the threshold of the sensor, by which when the sensed value raises above the threshold a corresponding action take place. This system is cost effective and will provide productive management in farming.

The GPS bus tracking and announcement system is an informative system present in both in the bus and the bus stop. It is designed for passengers travelling in the bus to know the details about the next coming stop and who are waiting in stop, regarding the nearing bus. This ensures that the passengers get enough time to get ready and also they won’t miss the right station. The existing system provides such facilities using the RFID technology which can be utilized only in the trains. But to implement it in the bus it would be more complicated and tedious as there are more stops, when compared to train. The proposed system overcomes these problems with a simple and effective architecture with GPS technology. The system consists of a GPS device that continuously monitors the location of the moving bus and using the GPS data from the device the voice data and a display of stop details is generated to be presented in the bus and subsequent display in the stop about the nearing bus.
Fast convergecast over a tree based routing technology for collision avoidance in wireless sensor network
In our task research the accompanying central inquiry how quick would information be able to be gathered from a wireless sensor network arrange composed as tree? To address this, we investigate and assess various distinctive strategies utilizing practical simulation models under the many-to-one correspondence worldview known as converge cast. We initially consider time scheduling on a single frequency channel with the point of limiting the quantity of availabilities required (schedule length) to finish a converge cast. Next, we consolidate scheduling with transmission control to alleviate the impacts of obstruction, and demonstrate that while control helps in diminishing the schedule length under a single frequency, scheduling transmissions utilizing multiple frequencies is more efficient. To attain efficient communication between the nodes, interference must be considered. We give bring down limits on the schedule length when interference is totally disposed of, and propose calculations that accomplish these limits. The utilization of multifrequency scheduling can get the job done to take out a large portion of the impedance. At that point, the information accumulation rate never again stays restricted by impedance yet by the topology of the routing tree To this end, we develop degree-compelled spanning trees and capacitated negligible spreading over trees, and show huge change in scheduling execution over various arrangement densities. Finally, we assess the effect of various obstruction and channel models on the schedule length.

R.Sumithra Thillaikannu, G.Amitha Stains Mary, R.Shanmugapriya, K.Srinivasan
Reinforced cement concrete is the most commonly used building material in India, as it is the convenient and economic system. This is true in the case of low rise buildings. The use of RCC is no longer economic for high rise buildings because of their increased dead load, decreased stiffness and hazardous formworks. The structures provide more deflection and ductility to the structures which is required to resist the seismic loads. According to literature use of composite steel-concrete system can provide durable, economic and seismic resistant structures. The composite structures are most appropriate in opposing seismic strength when compared to RCC. This paper compares the effectiveness of steel-concrete composite fames over traditional RCC for buildings by analysis and design of G+12 stories using E-tabs.

G.Amitha Stains Mary, S.Jayakumar, R.Shanmuga Priya, R.Sumithra Thillaikannu
Soil contamination or soil pollution is caused by the presence of xenobiotic chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals, or improper disposal of waste. Many industries dump their waste in their nearby surroundings. This action makes the soil sick by decreasing its fertility, and contaminates the ground water table of the region. Studies have revealed that contamination in soil leads to strength reduction and fertility .Due to this reason there is a high risk in taking up construction of buildings in and around the region. Bioremediation is emerging as a promising technology for the treatment of soil and groundwater contamination. This paper focuses on the treatment techniques of contaminated soil in Pondicherry region. The properties of the contaminated soil are determined and tested for the type of impurities present. Based on the behaviour of the soil the suitable remedial treatment is carried out in order to increase the fertility, strength and stability of the soil turning it out to be a suitable soil for either construction or cultivation. The Unconfined compression strength of un-contaminated clay was found to be 20 to 37 kPa. The paper also gives the treatment efficiency factor by comparing the aspects of contaminated soil with the clay available in agricultural field, which is assumed to 100 % fertile.

P.Shanmugapriya, S.Surya Bharathi, S.Karthika, M.Adhiyaman
In this paper a detailed study on the properties of Light weight artificial aggregates is carried out, these aggregates were made out by geo-polymerization. In the current scenario, the disposal problem of industrial by-products like fly ash has become an environmental issue due to the pollution caused. Further, shortage of land to fill these materials also adds up to this issue. Fly-ash is mainly used for the dumping purpose or as a fine aggregate. On the other side, shortage of natural aggregates in the growing infrastructure industry, creates problem of depleting natural resources which builds the need for artificial aggregates. In this project we aimed to develop a technique for producing an aggregate with the fly-ash and use it in the replacement of normal coarse aggregate. Consequently, the production of artificial aggregates solves two problems, conserves environment from pollution and prevents natural resource from depletion, thereby giving way tosustainable development. Artificial aggregates are prepared by pelletization process. The properties of artificial aggregate were compared with natural aggregate it found that the artificial aggregate results in light weight then compared to natural aggregate and it poses higher mechanical property than natural aggregate.
