— This paper provides remote controlling and automation for homes and offices. These are very essential in present life style. Wireless control is primary concern for everyone. This paper describes a design of effective remote control system that can monitor the house. Apart from remote control concern here we also take care of home automation. This paper gives the best solution for electrical power wastage. The home appliances are switched on/off using IR without actually going near to the switch boards or regulators. The water level of the tank can also be monitored and the motor can be controlled through automation.

There has been a very large increase in road accident due to drowsiness of driver while driving which leads to enormous fatal accidents .The driver lose his control when he falls sleep which leads to accident .This is because when the driver is not able to control his vehicle at very high speed on the road. This project can generate a model which can prevent such accidents. Temperature sensor and smoke sensor are used for further safety system in the vehicle.

Liquid dispenser machine is commonly found in our daily life in different places like offices, bus stands, railway stations, petrol pumps. In this thesis we are going to present a pneumatic operated oil dispenser machine. Using a pneumatic system interface, we can effectively increase operator accuracy, reduce training time and improve overall efficiencies, thus keeping cost down a properly designed pneumatic system interface can improve overall accuracy. Present liquid dispenser machine available in industries are costly, complex and hard in design and fabrication. Main requirement from this machine is its metering or measuring quality. Accuracy of measuring is very less in various machines. Hence, the basic theme behind this research is to improve these disadvantages of oil dispenser machine. The oil dispenser machine presently available is based on practice and past experience of the employer in his working field and also, its efficiency declines at a greater rate after a period of time. By surveying the present machines and comparing their present limitations, new model will be fabricated so that designs data can be obtained to formulate experimental data based model for this process. The design of model will be so simple that it can be adopted easily by small industries & automobile workshop. Easy technology will help to reduce metering problem. The present work reports the design & fabrication of oil measuring & dispensing machine which is used in small industries & automobile workshop.

The Power Quality (PQ), security, reliability etc., are the prime objectives of the power system. The protection is developed in such a way that it should be selective, fast, reliable and the cost effective. The study about the islanding protection in Low Voltage (LV) CIGRE distribution and networks like this has been proposed in this paper. This is achieved by developing the protection against the short circuit faults which might appear at the Medium Voltage (MV) bus. The protection of the network with significant penetration of the Distributed Generations (DGs) is a complicated process. The DG units which are directly connected to the grid such as synchronous or induction generators contribute large short power, whereas the DG units which are connected to the grid via inverters carry small amount of the short circuit power. This creates the problems in the protection of the network. If the proper protection coordination measures have not been taken, it might cause the mal-function of the protection devices which put the portion of the power network into the security threats. The selection of the islanding protection devices in this paper is made to protect the network against bi-directional currents at the time of short circuit fault. The LV CIGRE distribution network will enter into islanding if a fault is cleared at the MV bus by the proposed islanding protection devices. It is therefore, essential to detect the islanding in the CIGRE power network. The detection of the island in this network is another major objective of this paper. The detection of the island is proposed by using the technique which is based on the voltage phase angle difference. The simulations are carried out by using DIgSILENT power factory software version 15.0.

Agriculture sector in India is contributing to Indian economy to around 15 to 20 % when data of last
five year is considered. The products cultivated from this sector are mainly affected by the processing for
preservation. The developing countries of the world are lacking with facilities in agriculture sector and there
are several factors affecting agriculture. In India near about 50% people are directly or indirectly associated
with agriculture sector through farming and associated byproduct manufacturing. Agricultural application of
solar dryer is used widely in developed countries to preserve the vegetable. The preservation of many
products from agriculture is possible with solar dryers. The solar energy is available in India in abundant
amount. Use of solar energy for drying the product will be very economic. Authors have presented the
design of solar dryer in this paper.

Now a day’s child often falls down in the borehole which is left uncovered and gets trapped. It is very difficult and also risky to rescue the trapped children. A small delay in the rescue can lost the child his or her life. The objective of the paper is to construct and design a bore well rescue robot (i: e to rescue a trapped baby from bore well). This helps to controlled human robot that gives an insight view of rescuing the baby safely and steps taken to achieve this. This paper aims to design “Robot to rescue of a child in a bore well” which is capable of moving inside the pit. It is an innovative idea to rescue the children fallen into the bore well. This rescue operation is performed by combining motors, relays, sensors, micro controllers and camera to form a robot. The robot has an arm that possess a special gripping mechanism to rescue the child; in addition to that the position of the child can be observed with the help of the camera integrated with a light attached to it. In order to make the robot go inside the pit, a pulley control module is utilized which is integrated with the sensors. The robot consists of several motors to perform the necessary tasks. All the motors and sensors are interfaced by a PIC micro controller along with the LCD display from which the inside view can be seen through it.

There are two major ways to treat wastewater; it is either through chemical or non-chemical treatment. Both improve water quality, but do not make water safe for domestic use. Most firms or companies use coagulation treatment or chemical treatment. But the problem for this treatment is the selection of the best chemical to be used; it is expensive and frequent dosage adjustments are required to ensure good water treatment results. All coagulation chemical add specific elements to the water, improper doses and application generally pose problems (health risks). Hence, it requires extra preventive measures. A more cost-effective method to clean a wide range of polluted water on-site, and with minimal additives, is required for sustainable water management. Electrocoagulation treatment of water may fit this description [1]. Electrocoagulation is most widely used in other countries but not in the Philippines. Hence, the device readily available in the market is very expensive. The paper focuses on the automation of the Electrocoagulation process by using microcontroller, sensor, relays, and sacrificial anodes.

The very high data rates envisioned for fourth generation (4G) wireless systems in reasonably large areas do not appear to be feasible with the conventional cellular architecture due to two basic reasons. First, the transmission rates envisioned for 4G systems are two orders of magnitude higher than those of 3G systems. This demand creates serious power concerns. Second, the spectrum that will be released for 4G systems will almost certainly be located well above the 2 GHz band used by the 3G systems. The radio propagation in these bands is significantly more vulnerable to non lineof-sight conditions, which is the typical mode of operation in today’s urban cellular communications. The brute force solution to these two problems is to significantly increase the density of base stations, resulting in considerably higher deployment costs. So to reach these requirements more fundamental enhancements are necessary for the very ambitious throughput and coverage of future systems. It presen...
