 Abstract

The poultry farming is the raising of domesticated birds such as chickens and ducks for the purpose of farming meat or eggs for food. To ensure that the poultries remain productive, the poultry farms in Singapore are required to be maintained at a comfortable temperature. Cooling fans, with power ratings of tens of kilowatts, are usually installed to regulate the temperature in the farms .Besides cooling the farms, the wind energy produced by the cooling fans can be harnessed using wind turbines(WTs) to reduce the farms demand on the grid. The major difference between the situation in poultry farms and common wind farms is in the wind speed variability. In recent years, the research attention on dc grids has been resurging due to technological advancements in power electronics and energy storage devices ,and increase in the variety of dc loads and the penetration of dc distributed energy resources(DERs) such as solar photovoltaic and fuel cells. Many research works on dc micro grids have been conducted to facilitate the integration of various DERs and energy storage systems. In a dc micro grid based wind farm architecture in which each wind energy conversion unit consisting of a matrix converter, a high frequency transformer and a single-phase ac/dc converter are proposed. However, the proposed architecture increases the system complexity as three stages of conversion are required. In this project as an alternative solution we are proposing a dc grid based distribution network. Where the ac output of the wind generators (WGs) in a poultry form are rectified to a common voltage at the dc grid. Most significant advantage of the proposed system is that only the voltage at the dc grid has to be controlled for parallel operation of several WGs without the need to synchronize the voltage, frequency and phase thus allowing the WGs to be turned ON (or) OFF any time without causing disruptions.

 Abstract

All around the globe most usually utilized system is MANET as a result of its foundation free system. A self-created and composed framework communicates with the assistance of radio waves. MANET endures a great deal of security assault which can be inside or outer because of absence of brought together specialist. It is a major test in MANET to give security as there is no physical connection, no fix topology. The mainly objective is to distinguish and increase the execution of the system. In MANET distinctive kind of security methods has been proposed and the standard target of this paper is to think about them in detail.

 Abstract

In the present paper, a logical introduction of some mainstream aluminum frameworks that add to maintainability of structures is displayed. Unique accentuation has been given to the properties of aluminum, while the impact of these frameworks in the general execution of the structure in regards to condition and economy is portrayed. Specifically, qualities of aluminum components, for example, high reflectivity and recyclability and their part in life cycle investigation (LCA) are dissected. The associations between vitality effectiveness and protection of structures and aluminum application are additionally talked about. Building applications, for example, blind dividers, window casings and exterior sheets are introduced and completely examined, considering their natural and monetary angles.

 Abstract

Our project GSM based controlling of gun using DTMF technology, is an electromagnetic gun that can be controlled by a person at anywhere around the globe. The system use a DTMF (Dual Tone Multi Frequency) technology for controlling the coil gun. That can be make possible through the support of GSM (Global System for Mobile) network. The controlling process is carried out by the programmed microcontroller (AT89C52), which is more faster. The Electromagnetic Induction can be used to rifle the bullets, So we can easily increase the power of the gun by adding the number of coil stages and increase the number of turns. Our project is one of the safest and secured weapon.
