Natural fibres are most commonly and effectively used in concrete composites, due to their high specific strength, light weight and bio-degradability over synthetic fibres such as glass and carbon. In this study sisal fibres as natural fibres and glass fibres as synthetic fibre are used, and fibre reinforced composite system was developed. Chemical treatment (Alkali resistance treatment) was given to sisal fibre, to increase the interface adhesion between fibre and matrix and decrease in water absorption. Fibres were added to concrete in varying percentage of 0.5%, 1%, 1.5%, 2% in two grades of concrete namely M20 and M30. Mechanical properties such as compressive, split tensile and flexural strength of these two systems were checked and compared. Test results indicate that addition of sisal fibre in concrete gives high tensile and flexural strength, hence sisal fibres can incorporated as an alternative to glass fibre.

In the present research a series of experiments had been performed to make comparative study of various mechanical properties of concrete mixes prepared by Portland cement, Fly ash cement and their blend (in 1:0.5 and 1:1 proportion). Concrete mixes are modified by 5%, 10%, 15% and 20% of silica fume in replacement. The ingredients are mixed in 1: 1.5: 3 proportions. The properties studied are 3days, 14days and 28 days compressive strengths, workability and porosity.

What is the meaning of NGO, of course it a organisation which is owned by group of people of the society for certain cause and nonprofit basis .It simply work for the downtrod-den, Helpless, Children, Widows, orphans ,etc. Such as to run Hospitals, Old age Homes, Widow Homes, Orphanage Homes, Educational Institutes, Night Schools, for basic rights to the educated and un educated ,it also works for the farmers widow and their children, some time they under take some villages at the time earth quake and draught etc. The organisers work for common cause and without expecting any profit from the work. NGOs are confronting various issues which contrast from organisation to organisation, district to area. Some NGOs are even change the government, they force the government to adopt at all the states. Anna Hazare organisation is one of the best Example, who fought for the right of the common people. Mother Teresa’s organi-sation is another example who works for the betterment of the orphans in the tribal area. NGOs are only one organisation which work for No Profit. This type of Organisation help people to understand their legal rights. So that the society grow fast and spread peaceful atmosphere. NGO is a non-portable organisation with same mentality of different people they invest a small amount of money for a big cause. While working for the society these organisation will face rough weather from other partners underestimated, unpaged, Oppressed, down of the society. They evaluate of people underestimated, unpaged, Oppressed, down trodden, devastated, depressed and destitute they are never available objective gathering .NGOs tried to give every opportunity in real life and encouraging the common people to get their share in the society. Their fullest sup-port to the above said people will change the entire atmosphere of the society.

Wireless sensor network is the basic and simple way for measuring the quality of water by using wireless sensor network technology. In order to measure the quality of water for a real time application, the base station and their corresponding different sensor nodes are used to cover the large area. As this work has done in a remote area with limited access, the signal from various sensors will be collected and transmitted wirelessly to the base monitoring station. Therefore, the applications of wireless sensor network for the water quality measuring consists of a different sensor nodes. Such monitoring system will results into easy installation, easy handling, low cost and low maintenance system. The main purpose of this system is to measure pH level, water quality, temperature range and turbidity of water that may be used for specific purpose such as domestic, agriculture or industrial process. This system measures the above listed parameters by using wireless communication providing the quality control, record keeping and finally real time analysis using simulation software i.e Labview Software at base monitoring station.

Universities and school colleges waste their huge amount of money and man power in scheduling classes for their teachers and students hence ending up wasting such important resources also, student point of view regarding lectures and their interest regarding subject is ignored in this traditional way of formulating timetables. In this algorithm subject hardness as well as skill will be considered will subject slots on working day. This will be calculated using relative summation of those 2 parameters. For avoiding time slots collision based on calculated marks time slots gradient descent and other error minimizing machine learning tools will be used. Then the allocated time slots with their subject teachers will be fetched by website and then displayed to the authenticated users.

SMED (Single Minute Exchange of Dies) is a system for dramatically reducing the time it takes to complete equipment changeovers. The essence of the SMED system is to convert as many changeover steps as possible to “external” and to simplify and streamline the remaining steps. The name Single-Minute Exchange of Dies comes from the goal of reducing changeover times to the single Digits (i.e. less than 10 minutes). The applicability of the proposed SMED approaches can be seen by reviewing various research papers, which shows how SMED combined with various lean tools can be help in its successful implementation; this will enable reduction in setup time, through company’s internal resources reorganizations without the need of significant investment. Lean manufacturing is a concept of continuous improvement which emphasizes on the elimination of waste in the production system. To have an economical production, efforts have taken in the cycle time reduction to speed up the production rate, instead of focusing on the setup time reduction. This leads to the uneconomical small batch production. This paper describes how to reduce setup time by converts internal activities into the external activities. We have selected VMC machines for the setup time reduction with basic objective to reduced setup time by 30%. With implementation of SMED technique we could able to reduce setup time from 4 hour to 3 hour 10 min.
