LabVIEW controlled antenna positioner
An antenna rotator is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit, and the controller. The most commonly available antenna positioners are commercial rotators and sometimes some rotators are even complex to design and operate. Typically, Antenna Positioners are used to align larger antennas such as those used in Satellite Ground Stations to a fixed position. In contrast, Antenna Rotators and Antenna Rotating & Positioning Equipment are used for positioning of UHF/VHF communication antennas. The proposed design includes an azimuthal and elevation angle rotation system and is also capable of moving up to the accuracy of 1.8 to 0.9 degrees per step. The design also includes a user interface that is useful for easy control of the antenna positioner. NSI-MI Technologies rotary positioners are engineered to provide the optimum balance of outstanding performance, maximum power-density, and excellent application flexibility. In the center of the reference picture, the accompanying image includes an Az-El installation rotator, so named for its controlling of both the azimuth and the elevation components of the direction of an antenna system or array. Such antenna configurations are used in, for example, amateur-radio satellite or moon-bounce communications. ARA offers an ever-expanding line of positioning systems designed to satisfy the most demanding applications, including integrated antenna systems and RF systems. ARA positioning systems have been used successfully in both military and civilian systems and are successfully installed in ground-based, shipboard and airborne applications. The current rotator or positioner design aims to make use of lightweight payloads. In HAM radio applications, generally small weight antennas such as Yagi antennas, stacked Yagi antennas, antenna arrays, testing of microstrip antennas, and some RF chamber applications. This small-scale antenna positioner can be used for both indoor and outdoor applications. The indoor applications may like testing od antenna in the RF chambers and the outdoor applications involve satellite communications, weather image tracking, etc., and these outdoor applications are the most important in all.

Determination of fluoride content in water in Vellore District
Drinking water gracefully and sanitation in India keep on being deficient, regardless of longstanding endeavors by the different degrees of government and networks at improving inclusion. The degree of interest in water and sanitation, but low by global guidelines, has expanded in size during the 2000s. For instance, in 1980 country sanitation inclusion was evaluated at 1% and arrived at 65% in 2017. Additionally, the portion of Indians with access to improved wellsprings of water has expanded essentially from 72% in 1990 to 88% in 2008. Simultaneously, neighborhood government foundations accountable for working and keeping up the framework are viewed as frail and do not have the monetary assets to complete their capacities. What's more, just two Indian urban areas have persistent water gracefully and as indicated by a gauge from 2008 about 69% of Indians despite everything need access to improved sanitation offices. An investigation by Water Aid evaluated upwards of 157 million Indians, or 41 percent of Indians living in urban regions, are live without sufficient sanitation. India comes in the lead position all around for having the best number of urban-staying occupants living without sanitation. India beat the urban sanitation emergency, has the biggest number of urban tenants without sanitation, and the most open defecators with more than 41 million individuals.

Anarchism and Political Obligation
The political Obligation behind Anarchism was somewhat elusive all along. There have undoubtedly been almost as many anarchist values as there have been anarchists, but they can be broadly separated into two groups for analysis: the socially positive, and the socially negative. In several sources, the positive anarchist values have originated in William Godwin, but the negative aspects can be chiefly be traced to the influence of Max Stimer.

Subsoil water drainage system for building foundation structure
When the foundation is below water table level some amount of uplift pressure is applied on the surface of foundation, therefore current work is going on to remove or zero the uplift pressure by providing a subsoil water drainage system on building foundation. By using this technique, Cost control by making the uplift pressure zero resulting in less thickness of the raft slab. Saving in excavation, concrete, and steel, Time-saving & collected water in the sump is used for flushing purpose and landscaping.

The effect of friction on heat generation between surfaces
Friction is present in every aspect of the world where two objects move past each other. In some cases, they are useful and almost indispensable, like helping us walk, or letting cars slow down. In others, they are a nuisance, especially in motors and other mechanical applications which try to reduce friction as much as possible. However, it is an essential phenomenon to consider, especially in the design and construction of heavy machinery, cars, airplanes, and even robots. The heat has also been important to mankind since the beginning. It helps us keep warm and cook food. In this paper, I aim to test the effect of friction on heat generation between two surfaces. Research Question: How do the materials or surfaces involved in friction affect the heat generation due to friction from a grinder with surface velocity 26.3 ms-1 and an external force of 0.37N?

Utilization of STP Sludge and sugarcane pressed mud to manufacture bricks
In this study STP sludge and sugarcane press mud is used as a replacement material for fly ash brick. This study is done to reduce the STP sludge and sugarcane waste dumping in the earth to protect the environment from hazardous and also increment of low-cost brick towards the construction industry for the sustainable development. Bricks are the building material used for the construction of walls, pavements and other constructions. In previous days mud blocks were being used in construction but now clay bricks are used. While manufacturing the clay bricks the Carbon dioxide emission is more. Many attempts have been made to overcome these problems. So the industrial waste materials and the by products are used in the manufacturing of bricks. Here we have used the municipal sewage treatment plant sludge (STP) and the sugarcane waste produce i.e. press mud with fly ash and lime so that we get the binding and compressive strength in good amount. Here the bricks are done without burning, so the greenhouse gas emission is minimized. The press mud is a material which is obtained from the clarification of sugar. The disposal of this waste into the environment causes the land pollution so this study will be a better solution for this problem. The municipal sewage sludge and sugarcane press mud are added at different percentages such as 10, 15, 20 and 25.
