Pedestrian are the most vulnerable users of the road. There are millions of vehicles on the road and the conditions such as inclement weather, poor lightning, traffic and other road hazards restrict the visibility of drivers which increases the risk to pedestrian. In addition, human error is known to be one of the leading causes of accidents. This paper focuses on detection of pedestrian using real time video stream. Video is captured using Raspberry Pi camera module. Along with this Haar cascade classifiers are used as a technique to detect pedestrian in the video captured. An additional security is provided using obstacle detection implemented using an Ultrasonic sensor and speed control using PWM technique based on the position of the obstacle detected.

Even though the presence of waste to energy industry in past decade most of the solid wastes do end up in landfills. For every tonne of waste land filled, greenhouse gas emissions in the form of carbon dioxide increase by at least 1.3 tonnes. Gasification is a promising technology which would help deal with the landfill problems and would rather convert the municipal solid waste (MSW) into an energy source. Gasification is a process in which a solid carbonaceous fuel is transformed into combustible gas consisting of carbon monoxide, hydrogen, carbon dioxide and methane. This process is achieved by reacting the fuel at high temperatures, without combustion, with controlled amount of oxygen or steam. This gas is known as producer gas which acts much efficient than the direct combustion of the fuel. In this study an updraft gasifier is fabricated and is used to carry out the experiment. The solid non-recyclable wastes like china cardboards, clothes, wet newspapers, etc, are used for the generation of the producer gas. A gas analyzer is used to measure H2, CH4, and CO concentrations of the product gas. The study investigates the aspect of municipal solid waste as potential energy source in gasification technology.

This paper explores the various protections for Induction Motor using Fuzzy Logic controller. Induction motor is the most widely used motor in the industry due to its simple and rugged construction. It requires least maintenance as compare to the other electrical motors Mainly the induction motor needs protection from the variation of the input supply. For the proposed protections three inputs are applied to the Fuzzy Logic Controller to attain the objective. The inputs provided to the FIS editor are Current, voltage and Time. Current sensor is employed to sense a single phasing, any undesirable increase in current and time is calculated when this overcurrent appears and voltage sensors are provided to the controller for voltage protections. main objective is to limit the current and turn the motor OFF whenever necessary during undesirable changes in voltage and current. For an unsustainable high current for a longer time or during single phasing or during under/over voltage condition the motor is turned OFF.

Selection of a proper Facilities Layout (FL) to accommodate a particular type of manufacturing environment is a Herculean task. Multi-Criteria Decision Making (MCDM) approaches provide comprehensive solutions to FL selection problems, so that an efficient and cost effective FL can be selected from amongst many. These tools also provide a mechanism that can handle complementary, conflicting and even contradictory factors. Analytical Hierarchy Process (AHP) is one such tool. Here, Decisions Matrix and Pair wise Comparison (PWCP) matrices are formed on the basis of objective and subjective evaluation of a given scenario and corresponding Priority Vector (PV) values are calculated. These PV values are calculated through iterative process and are accepted if the concerned matrices yield Consistency Ratios (CR) below a specific limit. Then Composite Priority (CP) values are found out and used as Subjective Factor Measure (SFM)s in determining Facility Layout Measure (FLM)s. The algorithm is coded in ‘C’ language. The program is general and can be used to handle varieties of ‘selection from amongst many’ kind of problems. In the next step, a Sensitivity Analysis is taken up, to estimate the model’s performance when subjected to minor changes where CP values are used as SFMs in determining FLMs.

Plastic extrusion process is a well-known technique widely used in the polymerization industry. In order to produce a good quality of plastic product, the temperature in each zone must be appropriately set and precisely controlled. The temperature of the plastic extrusion system has a wide range of variation subject to various disturbances. The system is generally nonlinear and so, controlling the temperature is a tedious process, as it has multiple stages and the system is coupled with each other. Plastic extrusion barrel temperature has slow response. During the transition, from the ideal state of the machine to the operation state, the temperature variation exists significantly in the temperature zones, which in turn, lead to unstable melting temperatures and inconsistent product quality.

Why should we teach life-skills to the students of twenty first century? If we observe the present scenario of the students at both the Post-Graduate and Undergraduate levels, they are good at securing grades and ranks. But they are unable to become employable. The recent statistics says that the only 15% of them are able to be employable. What about the remaining 85% of the students? Though they are good at their subject matter, they are not able for employability, to possess the required skills and qualities. If one wants to be employable, one should be skilled not only in one’s subjects, but also one should be skilled in Behavioural, Attitudinal, and Character related aspects too. Besides, one should be able to intelligently deal with time, money and men in decision making. As English teachers we have a lot of scope to develop our students not only in communication skills but also in life-skills. As per the present context, in the present generation/in the young minds there is no seriousness and proper caring about their lives and even lagging behind in maintaining or balancing the relationships properly with their own family members, teachers, friends, and even with the neighbours. I think the teacher is the right person in moulding their minds to keep them in a right track. In this process to overcome the imbalances we can use literature as an aid or an instrument to teach life skills and make them employable and real citizens of the nation.

Climate projections suggest the frequency and intensity of some environmental extremes will be affected in the future due to a changing climate. Ecosystems and the various sectors of human activity are sensitive to extreme weather events, such as heavy rains and floods, droughts and high and low temperatures, especially when they occur over prolonged periods. In 1985 Wigley studied about extreme events dangerously affected human society which is included among others agriculture, water resources, energy demand and mortality. In this paper, extreme elevated temperature events for nearly 117 years from the Minneapolis/St Paul, Minnesota State, and area are analyzed from the major international airport [St. Paul] and popular city in Minnesota. The main aim of this study is to find the best fitting distribution to the extreme daily temperature measured over the Minneapolis region for the years 1900-2016 by using the maximum likelihood approach. The study also predicts the extreme temperature for return periods and their confidence bands. In this paper, extreme temperature events are defined by two different methods based on (1) the annual maximums of the daily temperature, (2) the daily temperature exceeds some specific threshold value and (3) Bayesian Model using Markov chain Monte Carlo (MCMC). The Generalized Extreme Value distribution and the Generalized Pareto distribution are fitted to data corresponding to the methods 1 and 2 to describe the extremes of temperature and to predict its future behavior. Finally, we find the evidence to suggest that the Frechet distribution provides the most appropriate model for the annual maximums of daily temperature after removing an outlier and the Generalized Pareto Distribution (GPD) gives the reasonable model for the daily temperature data over the threshold value of 96°F for the Minneapolis location. Further, we derive estimates of 2, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150 and 200 years return levels and its corresponding confidence intervals for extreme temperature.

In this paper we have designed Adaptive Neuro fuzzy Inference System (ANFIS) controller for the speed control of bidirectional brushless DC motor (BLDC).The fuzzy models under the framework of adaptive networks are called Adaptive-Neuro Fuzzy Inference System. The ANFIS controller is used in three phase BLDC Motor drive system to control the four quadrants operations without loss of power. In this process energy is conserved during the regenerative period and storage of excess energy in battery takes place during regenerative braking. The bidirectional DC-DC converter is used for the battery charging and discharging purpose. The bidirectional dc-dc converter can be operated in buck-boost mode. The stored energy in the battery provides power to the BLDC motor in motoring mode, while during regenerative braking mode the energy is fed back to the source by the same bidirectional buck-boost converter. The simulation will be done for Brushless DC motor with ANFIS controller using MATLAB/Simulink software the effectiveness of the proposed ANFIS controller is compared with that of thefuzzy controller.

Historically, Northern Province has been a vibrant economic hub, with an educated population and an entrepreneurial workforce. But the people have faced numerous hardships over the years. Many have left due to the conflict, and there is a sizeable group living in vulnerable condition. Conflict has severely curbed economic activity too, with production falling sharply in all crops and manufacturing output also dropping. There are no signs of recovery and the take-off in GDP of the Northern Province. Many credits this to the strong tripartite efforts by government, chambers of commerce and private businesses. The setting up of Dedicated Economic Centers (DECs) was started in 1998 in Sri Lanka, as means of implementing marketing development strategy to provide marketing facilities for producers in the rural areas. Recently, the DEC for Northern Province is a problematic aspect for suitable site selection for the construction activity. Developmental Officers, Public and Politicians are discussing this in different ways but no one did do any proper research and analysis for the suitable site selection. However, the constructions activities have started at Mathakuvaithakulam in Vavuniya District but people are opposing against for this site selection for the construction. Therefore, the researcher applied the Analytic Hierarchy Process (AHP) analysis method for the appropriate site selection for the DEC for Northern Province. The main objective of this study is to identify the suitable site for the DEC for Northern Province using AHP technique by reporting criteria to indicate important aspects with multi-criteria decision analysis method. According to ultimate synthesis results, the Maankulam was selected as a most appropriate site with the 0,235 performance score compared with other three areas. This model and priority area could be used for the decision making among a larger outline of the problems. Development officers and decision makers should be considered this type of analysis and result for the site selection and implementation of the projects.

The world is being aware of the pernicious effects of the unwanted and unavoidable parameter like exhaust emission from automobiles and the need to control them. Presently, Three-Way Catalytic Converter (TWC) is an important after treatment device to reduce damaging engine exhaust emissions. Platinum group metals well known as non-noble metals have shown greater pollution-control capability, but due to cost considerations, these metals are used in lesser quantities. This dissertation focuses on controlling the automobile emissions using the combination of nano-particles of non-noble metal i.e. Ruthenium Catalyst to better level. In recent years, use of nano technology in the field of energy, environment, medical and information technologies has been rapidly increased due to the interesting physical and chemical properties of the nano materials arising from the quantum size effect which is remarkably different from those in bulk samples. Numbers of experimentations have been made by many researchers using NPs of various catalyst materials and analyzed for their effect on the TWC and the results have reported remarkable enhancement in the performance of TWC. So it becomes important to review the various methods of NPs preparations synthesis and their effect on the properties of the materials and characterization of the NPs for evaluation of various properties of the same. The TWC model is developed for Tata Indica Four Stroke Four Cylinder Diesel Engine of 1405 cc capacity. Space velocity was found an important consideration while designing TWC. The use of non-noble metal catalysts for the developed model of TWC has shown 12.66 to 63.67 % control over CO emissions, 3.66 to 56.58 % over HC emissions and 12.35 to 29.64%over NO emissions.

A system that supports a driver in traffic situations and reduces the total driver workload is a growing research topic. Several of these support systems aim toward full or partial automatic driver assistance, such as those for longitudinal control that are often called Adaptive Cruise Control (ACC) systems. Adaptive cruise control distinguishes itself from cruise control in its use of sensors that measure the headway distance and a controller which adjusts the velocity and distance to the vehicle in front. Adaptive cruise control requires appropriate sensor technology, actuators and control devices and its system design requires data acquisition, control system design and validation procedures. The motivation for these systems is that they aim at increasing the driving comfort, reducing traffic accidents and increasing the traffic flow throughput. The ACC systems autonomously adjust the vehicle’s speed according to current driving conditions. In order to accomplish driver comfort the system must resemble driver behaviour in traffic. Simulation results prove the utility of the system.

China’s rise, its form, and implications have been a topical issue among international relations experts long before Xi Jinping assumed office as the General-Secretary of the Communist Party of China and President of the People’s Republic of China (the world’s most populous nation). Nevertheless, since 2012 (when President Xi took over the mantle of leadership of the country), questions of whether or not China is a threat to the existing international order, a revisionist state or a regional hegemon, have increased. Compared to his predecessors, Xi is said to be a more assertive and an ambitious leader. He presides over an economically viable and militarily powerful nation. The fact that China’s influence is increasing in global and regional affairs having survived the Asian Financial Crisis of 1997, sends shivers down the spine of its neighbors as they seem oblivious to her motives.
