 Abstract

This paper proposes the development of a home automation voice command system. The system was modelled using some of the UML elements in a way to be flexible, and adaptable towards any residence structure. That means that, any user is able to dynamically add and remove electrical devices into the system without the help of a technician. It was designed an Android cellphone application, which communicates in a local network with an Arduino board. In order to assess the system, it was built a miniaturized residence to test it in a real case scenario. The findings suggest that the system works relatively well; however, there were a few instances that the system could not recognize the content properly.

 Abstract

Biodiesel is an alternative to conventional diesel fuel made from renewable resources, such as non-edible vegetable oils. The oil from seeds (e.g., Jatropha and Pongamia) can be converted to a fuel commonly referred to as "Biodiesel." No engine modifications are required to use biodiesel in place of petroleum-based diesel. Biodiesel can be mixed with petroleum-based diesel in any proportion. This interest is based on a number of properties of biodiesel including the fact that it is produced from a renewable domestic source, its biodegradability, and its potential to reduce exhaust emissions. The climate change is presently an important element of energy use and development. Biodiesel is considered "climate neutral" because all of the carbon dioxide released during consumption had been sequestered out of the atmosphere during crop growth. The use of biodiesel resulted in lower emissions of unburned hydrocarbons, carbon monoxide, and particulate matter. Biodiesel also increased catalytic converter efficiency in reducing particulate emissions. Chemical characterization also revealed lower levels of some toxic and reactive hydrocarbon species when biodiesel fuels were used. The fuel consumption in the world particularly in developing countries has been growing at alarming rate. Petroleum prices approaching record highs and they will deplete within few decades, it is clear that more can be done to utilize domestic non-edible oils while enhancing our energy security. The economic benefits include support to the agriculture sector, tremendous employment opportunities in plantation and processing. Jatropha and Pongamia are known just crude plants which grow on eroded soils and require a hot climate and hardly any water to survive. These are the strong reasons, enforcing the development of biodiesel plants

 Abstract

The safe and time efficient movement of the people and goods is dependent on Traffic flow, which is directly connected to the traffic characteristics. The three main parameters of a traffic flow are volume, speed and density. In the absence of effective planning and traffic management of the city, the current road infrastructure cannot cater the future needs of the city. Pedestrian and vehicle volumes have increased significantly in the last decade due to the change of the economics of the middle-class families. Traffic flow is studied by manual methods. For better understanding of the present status of traffic flow at the junction, traffic survey is conducted. With the help of the data collection, an attempt had been made to understand the traffic patterns during different time periods. Traffic control at that junction is also dependent on the traffic flow characteristics. Hence the results from the present study are helpful in controlling the traffic at the intersection and also in suggesting some of the remedial measures to improve the traffic safety in the region. Traffic Engineering therefore deals with the applications of scientific principles, tools, techniques and findings for safe, rapid, convenient and economic movement of people and goods.

 Abstract

Fire alarm system is a combination of number of devices working together to detect and warn the people through a visual and audible appliances when smoke and/or fire are present. The alarm used in such system may be activated from flame or smoke detectors and heat detectors. Alarms can be either motorized bells or wall mountable sounders or horns. Fire alarm system plays the main role in maintaining and monitoring the safety in all kinds of environments and situations. However, the usability of many existing fire alarm and detection system is well known but the primary constraint is the high cost. The main objective of this Fire Alarm Control System in Building Automation Using PLC is to make a fire control and suppression system with high reliability and low cost. The Fire Alarm Control System based on PLC has three main systems: 1) the detection of fire, 2) the monitoring system and 3) the appliance system in which the main door will get opened and lift will come to ground floor for safety purpose. The detection system operates as the fire detector. This detection system has components like bimetallic strips as a flame detector, smoke detector, and heat detector.

 Abstract

Aluminium matrix composites (AMCs) have gained importance in various industries because of their good properties such as wear resistance, low density, high strength and good structural rigidity. Aluminium metal matrix composites are preferred in the field of aerospace, military, automobile, marine and many other domestic applications. The aluminium matrix can be strengthen by reinforcing with hard ceramics particles like SiC, Al2O3, B4C, etc .in the present work aluminium LM6 alloy was chosen as matrix material and born carbide particulate of 25 microns size is chosen as the reinforcement with varying weight percentages. The composite is prepared by using sand casting techniques. The hardness and the impact behavior of prepare composite were examine. Hardness of AlLm6 was increased and impacted strength was decreased by addition of B4C particles. Scanning electron microscopy (SEM) micrographs reveal the uniform distribution of B4C particle in aluminium alloy.
