The combustion of oil shale can extract the kerogen and later transform the kerogen in to heavy oil .The only drawback of this technique is the decarbonation of mineral matter in shale by high temperatures. This process causes 60% to 70% of the CO2 and CO emissions. The decarbonation of CaCO3 and oxidation of fixed carbon causes the formation of CO2 and CO .The aim of this study is to avoid the decarbonation by decreasing the temperature in the retort of combustion. During this experiment we tested the impact of two parameters: Firstly, decreasing the quantity of fixed carbon in the medium of combustion and secondly, increasing the amount of carbonates which acts as heat dissipater. It is demonstrated that increasing the amount of carbonates may only decrease the medium of combustion to temperatures not lower than 830°C which is still so high to avoid decarbonation. Moreover, the temperature can be decreased to avoid decarbonation by reducing the quantity of fixed carbon .When the medium reached the low temperatures, nearly all the fixed carbon is oxidized. In high temperatures decarbonation of the mineral matter present in oil shale produce huge emissions of CO2.We show, in this paper a new approach to controlling the temperature of the combustion to prevent this decarbonation .

In the present paper, we presented the study of complaints on thirteen (13) different health symptoms faced by inhabitants living near mobile tower – Global System for Mobile Communication (GSM 900) and those inhabitants living in the area where there is no mobile tower. The study was conducted in two different localities in Aizawl city in the year 2014. For the study, questionnaires were conducted in both the localities. Power densities were measured in different places in both the localities. Frequency spectrum was taken in each locality. Health complaints between the two localities were compared. It was found that power density is much higher in the area where there is mobile tower than the area where there is no mobile tower. Inhabitants living near mobile tower are having more health complaints than those inhabitants living in the area where there is no mobile tower. Responses from inhabitants who participated in the questionnaires from both the localities were statistically analysed and compared by performing Kruskal Walli's t-test. Out of the thirteen (13) different symptoms studied it was found that the comparisons are statistically significant with p < 0.05 in four (4) symptoms. Women were statistically more affected (p < 0.05) than male in headache and muscle pain.

In this paper a hardware module of Laser based guidance system for projectile has been developed.The system uses a laser beam to guide a projectile to precisely hit a target. The guiding system generates a laser beam trajectory bygetting the range of target and velocity of projectile input manually.The guidance system in the projectile interpret the information contained in the laser beam and steers to track the beam to keep the projectile closer to the centre of the laser beam. Such guided projectiles can thus said to "ride" the beam to its target.The main aim is to design and develop a microcontroller based platform with two degrees of freedom(Azimuth and Elevation) with optical zoom facility to keep the diameter of the laser beam as a function of distance.In this project the line of sight will be on a static target. The trajectory of laser beam from the above system can be used as a guidance system for beam rider missiles. The project relates the azimuth, elevation and the optical zoom movement to generate the desired trajectory.

Sabotage operations on petrol pipe lines happen all over the world. The saboteurs aim from such operations is to hinder the petrol exportation process. The sabotage operations on petrol pipe lines causes a spilling of a large amount of petrol from the pipe lines. Sabotage of the petrol pipe lines also causes fires and pollution to the environments . Such operations causes a lot of loss in economy to the country concerned where the sabotage took place. This paper sheds the light on this challenging issue to steady and propose an intelligent electronic circuit design solutions to this problem. An electronic circuit design based on using a Field Programmable Gate Array (FPGA) is proposed to reduce to minimum the amount of petrol spilling when a sabotage on the petrol pipe lines happens. A real time sensing and response electronic circuit is implemented to fulfill this task .The system design is programmable (i.e intelligent) and hence the electronic actions established in the design can be modified easily. An electronic interface circuit is deigned to be connected to the (FPGA).The task of the electronic interface circuit is to acquire data from the sensors installed on the petrol pipe line and to give commands to the electronic and electrical devices to stop the pumping operation and to close the petrol pipe line immediately. Many electrically controlled pipe closing valves are to be installed along the pipe line. These electronic closing valves are remotely controlled by the embedded system based on the (FPGA).

Collection and treatment of urban solid waste and domestic sewage are essential sanitary services for the population, but in many countries as Brazil these services are defficient. In São Luís-MA, municipality with more than one million inhabitants are generated about 414 thousands ton/year of municipal solid waste and about 190 million cubic meters of domestic sewage per day. Their collection and treatment have been one of the biggest challenges for municipal administrators. This paper proposes techniques for treatment of municipal solid waste and domestic sewage with energy recovery and minimization of environmental impacts by recycling, biodigestion and incineration. The results show that reuse of 10% of the potential of recyclables can annually generate financial gains of R$ 6 million/year (US$ 2,7 million); the landfill biogas when converted to electricity can be enough for 5.5 thousand homes while MSW is incinerated it can produce electricity sufficient for 24% of the residences of the city. Both biogas of sewage and heat of incineration can generate energy sufficient for 3% of the homes in the municipality. The treated wastewater is sufficient for 45% of the homes in São Luis which has a deficit of 41.7% of homes without to treated water.

Senior citizens have to make frequent visits to their doctor to get their vital signs measured. The objective of this work is to design and implement a reliable system that can be used on regular basis to monitor the vital signs and obtain the readings on the LCD and also on doctor's mobile. This work specifically deals with signal conditioning and data acquisition of measurement of temperature and pulse rate. Temperature is measured using LM 35 by placing it on the surface of the body and pulse rate using pulse sensor. This information is processed and displayed on the LCD and also sent to the doctor using GSM. Statistical techniques like correlation, regression, t –test and F-test are applied for comparing the readings taken by the doctor and this system. This work is useful for old people at home, in ambulance and at remote health centre's where the availability of doctor is always not possible. The theory, design procedures, experimental results and discussions of these systems are presented.

Footing element in structures plays very important role. Different types of footing are used in struc-ture with respect to axial forces, nature of soil, earthquake zone, locality, etc. In this project, pad and pile footing in a residential building are mainly considered by considering two different models. It is very important to study the effect of these two in the structure according to the axial forces. To study the effect on costing as we replace the regular footing i.e. pad footing by pile footing, analysis is done. We take two RCC building with G+ 4 storey and analyze them with Staad-Pro assuming the same soil and other conditions. Manual design of all the footings in both cases is also done. Cost difference of two footings is also observed. Inter relations are obtained between axial forces and approximate cost of pad and pile footings. Mathematical models are developed for having ap-proximate cost of one type of footing from another.

This work presents an application of Wireless Sensor Network (WSN) of random access with one-way transmission to the monitoring of hospital patients. In this project we will study a clustered wireless sensor network where sensors within each cluster forward the message to another cluster via cooperative communication techniques. In WSN, several architectures usually called network topologies are possible: star, cluster-tree and mesh. In different topologies, sensor nodes can act as simple data transmitters and receivers or routers working in a multi-hop fashion. Other wireless networks are not as energy constrained as WSNs, because they may be plugged into the mains supply or equipped with batteries that are rechargeable and replaceable. The nodes of the proposed wireless sensor network are created by using a combination of various sensors a CC2500 low power wireless radio.

Development of an automated real-time remote measurement and monitoring of weather parameters system is presented .This work brings forward new programmable device for remote real-time measurement and monitoring of weather parameters. Three levels are included in the system: the microcontroller for information processing using atmega32 with a control program for real time measurement, processing and monitoring, GSM unit to provide wireless communication via cell phones for monitoring of weather parameters, with the aid of sensors (temperature, humidity, wind speed, pressure sensors). RF transmitter is used to collect and transmit data from field to the controller which includes RF receiver. The System operates in two modes: the first one is for real time transmitting of data through fixed time intervals, these intervals are set via key pad according to the user requirement and GSM sharing between the different sensors. A real time clock (RTC) is used for time adjustment. The second mode is used in case of regular collection of data as well as rain fall expectation, where the data is to be collected in regular intervals,. In this mode the user can exclaim the system about the weather parameters (temperature, humidity, dew point and rainfall) ,then the user will receive a real time feedback SMS explaining the weather conditions.
