Deployment, coverage and energy efficiency are the main goals set in wireless sensor network. The network constituted by the small sensor nodes having the three main tasks of sensing, data processing and forwarding with the aim to reach base station. The base station works as the sink for the data which is generated by the sensor nodes in case of wireless sensor networks. The sensor networks have the limited battery supply for the use in sensor nodes. Each node can transmit data in its communication range. The communication range can be affected with the change in battery utilization. In this paper, the main focus is shifted to deployment, coverage and energy aware operation methodology which in term help to increase the efficiency of the overall network. The network resulted in the higher performance parameters. Obtaining optimal results remain the objective of the work throughout the process of simulation undertaken.

An analysis of the effect of orientation on the heat transfer in a scaled model pin fin heat sink utilized in Light Emitting Diode (LED) lighting has been carried out using numerical method. The present study involves natural convective heat transfer that takes place in particular heat sink. A pin fin type heat sink has been studied since they are widely used in LED lighting systems which in turn are facing a lot of thermal challenges when they are integrated with high power lighting system. The numerical study is carried out using ANSYS FLUENT software package. The modeling and meshing has been generated using ANSYS GAMBIT v.2.3.16 module which one later imported into ANSYS FLUENT v.6.3.26 module for analysis. In order to carry out a detailed analysis various parametric studies are conducted for different LED power wattages such as 10 W considering different orientations obtained by changing the angles from 0° to 45° has been carried out. From the results it can be concluded that the dissipation of heat in the heat sink is dependent on the orientation of the heat sink. The particular study will be useful to optimize the heat sink used in the LED lighting system.

Internet usage is increasing day by day as well as the attacks on the sites. Distributed denial of service (DDoS) is one of the such type of attacks. DDoS disable the server by flooding invalid requests with invalid or spoofed addresses, due to this the server’s buffer gets overloaded and bandwidth of server get exhausted and server stop its services. Left undetected, can be very dangerous to the entire network. If organizations can detect these types of attack in advance then organizations will be saved from loss of these attacks, there is much prevention techniques which can detect these types of attack but while choosing one of these technique questions arise which technique should be used? Which is the best? IP Traceback technique is a DDoS detection technique, which is used to trace the path of an IP packet to its origin so one can find out the true identity of the attacker and can detect the path characteristics. Different types of IP Traceback Techniques are available. In this paper we study different IP Traceback techniques.

Solar energy is one of the most abundant sources of renewable energy for the future. This solar energy can be extracted by PV system. Many methods for PV installation are carried out, such as roof top PV system, dam top PV system; floating PV, canal top PV system etc. In canal top system, PV panels are placed above the water canal which saves installation area and reduces evaporation loss. The performance of any PV system depends mainly on the light intensity, so by a concentrating PV system power output can be increased. The usage of concentrated PV system can bring down the investment cost per kWh. In this paper canal top PV system with reflectors in the inter array spacing are studied. The expected advantage of such a system is that the evaporation loss can be further reduced and additional cooling system may not be required. To get uniform availability of light and to avoid shading on the panels, tilt angle of the panel, inter array spacing and orientation of the reflectors are calculated optimally.

This paper describes three tests on small scale, transversely stiffened plate girder. The objective of the test was to observe collapse mechanism and to study post buckling behavior i.e.in particular to investigate the behavior of the transverse web stiffeners. A problem was selected to choose the dimensions and loads of the plate girder and design can be solved according to clauses of Indian Standers 800-2007. Model analysis technique was used to reduce the dimensions and loads of actual structure. Accordingly three small scale plate girder models were constructed with varying number of stiffeners and with constant dimensions of web, flange and stiffeners. The main objective of this experimental study was to study post buckling behavior. The observation given should facilitate future development of improved method of stiffeners.

The main aim of this study is to investigate the effect of injection pressures on emission and performance analysis of biomedical waste pyrolysis oil, plastic waste oil and its blends with diesel using diesel engine. This research describe a comparison of the use of pyrolysis oil i.e plastic pyrolysis oil which is extracted from biomedical wastes and normal diesel oil for different injection pressures in the assessment of engine performance, characteristics, and feasibility analysis. .The parameters like brake thermal efficiency, brake specific fuel consumption, and exhaust emissions like NOx, CO2, CO, and mass fraction burned., were considered for comparing the performance of pyrolysis oil in various proportions and with varying loads at two injection pressure i,e 180 and 200 bar. The initial experiments were done at injection pressure of 180 bars, later the injection pressure was changed to 200 bars. It was observed that the brake thermal efficiency increased as the injection pressure increased from 180 bars to 200 bars. The NOx emission reduced as the injection pressure was increased to the CO emission gradually decreases as the injection pressure increased. It was observed that addition of oxygenates had improved the combustion process and reduced the emissions. The investigation revealed that blending of DEE with plastic oil increases the Cetyane rating which is superior to neat diesel. The economic analysis shows that the pyrolysis oil is able to replace diesel in terms of engine performance and energy output if the price of pyrolysis oil is not greater than 85% of diesel oil.

Emotion Generation and Summarization form Affective Text deals with new aspect for categorizing the document based on the emotions such as Empathy, Touched, Boredom, Warmness, Amusement and Surprise. In order to predict the emotion contained in content a proposed model i.e. Emotion Topic Model is used. Using this it first generates a latent topic from emotions, followed by generating affective terms from each topic. First it separates emotion and word document and derived probabilities for it. The model which we proposed will utilize the complementary advantages of both emotion-term model and topic model. Emotion-topic model allows associating the terms i.e. words and emotions via topics which is more flexible. For classification we have used Naive Bayesian algorithm and Iteration based Nearest Neighbor Algorithm which will predict emotion accurately. For each emotion, we will be displaying emoticon and songs recommendation will be available for user. So that in future user can upload and enjoy their own choice of song based on their emotion which is detected from text.

The wheelchair is one of the most commonly used assistive devices for enhancing personal mobility, which is a precondition for enjoying human rights and living in dignity and assists people with disabilities to become more productive members of their communities. For many people, an appropriate, well-designed and well-fitted wheelchair can be the first step towards inclusion and participation in society. When the need is not met, people with disabilities are isolated and do not have access to the same opportunities as others within their own communities. Providing wheelchairs that are fit for the purpose not only enhances mobility but begins a process of opening up a world of education, work and social life . The development of national policies and increased training opportunities in the design, production and supply of wheelchairs are essential next steps. Every human being need to move from one place another to fulfill his requirements and to accomplish that requirements he will travel from one place to another place by walking which is a basic medium of transportation. But it is exceptional in case of physically disables (Persons don’t have both legs). In order to support and help such a person’s we designed a special manually lever operated wheel chair. This wheel chair helps the physically challenged persons to lead their normal life like normal being without the help of any one in their movements from one place to another place and to carry out their work. The wheels are of Special shock absorbing type. This device is designed in such a way that we can use for both indoor and outdoor applications.

This paper proposed scheme for the Sensor-less BLDC motor drive fed by a Zeta based PFC converter operating in DICM. The front end Zeta DC-DC converter maintains the DC link voltage to a set reference value. Switch of the Zeta converter is to be operated at high switching frequency for effective control and small size of components like inductors. A sensor-less approach is used to detect the rotor position for electronic commutation. A blind startup is used for starting the BLDC motor. A high frequency MOSFET of suitable rating is used in the front end converter for its high frequency operation whereas an IGBT’s (Insulated Gate Bipolar Transistor) are used in the VSI for low frequency operation. The proposed scheme maintains high power factor and low THD of the AC source current while controlling rotor speed equal to the set reference speed.

Biogas is one of beneficial and essential gas, which is widely used for the electricity, heat and transportation fuels. Biogas can be produced by digestion pyrolysis or hydro gasification. Digestion is a biological process that occurs in the absence of O2 and presence of anaerobic organisms. The container in which the digestion takes place is called digester. In this work, the Biogas was produced through anaerobic digestion process at atmospheric pressure and the best temperatures between 30 - 65°C. When the temperature is below 15°C almost no gas is made. In this experiment, the food waste was incubated with sludge water in a tightly sealed container. Aerobic decomposition occurs first and CO2 was produced while oxygen was consumed, once the oxygen has been depleted, the methanogen bacteria start growing and consumes the CO2 to produce biogas. Therefore, one should expect an initial increase in CO2 production followed by a decrease in CO2 and a steady increase in methane production. The biogas obtained at the end of the reaction will be a mixture of CO2 and CH4. The CO2 can be monitored using a CO2 detection probe. The methane can be identified by burning it. The methane gas was collected in the plastic bottle to measure it by water displacement and then test it by using a Bunsen burner.
