A Five Phase Axial Flux Permanent Magnet Generator for Wind Turbine Application
This project discusses the benefits of five-phase technology for Wind Turbine Application with Axial Flux Permanent Magnet BLDC Generator (AFPMG). The radial flux permanent magnet generator has a setback of very low-speed applications because of the presence of cogging torque. This can be overcome by using an axial flux permanent magnet generator which has no cogging torque and has more advantage than a radial flux generator. Investigations proved that the five-phase topology harnesses some specific and important benefits that are not provided by three-phase systems. The benefits include improved fault tolerance and reliability, and reduced voltage, torque ripple, and size of DC link capacitor. These are general improvements that are sought after in many applications including renewable energy applications. The objective of the project is to design a five-phase Axial Flux permanent magnet BLDC generator for 1000W at a wind speed of 9m/s. Performance analysis of Axial Flux permanent magnet is investigated. MATLAB/Simulink model for five phase rectifier and Generator model is discussed. Test results are also presented in this project

Comparative Study on Fresh and Hardened Concrete Properties of Ternary Blend Self Compacting Concrete
Self- Compacting Concrete is a special type of concrete that is able to flow and compact under its own weight and can occupy all the spaces in the form without any vibration and at the same time it is cohesive enough to be handled without bleeding or segregation. In recent years, self-compacting concrete has been gaining wide range of application for placement in congested reinforced concrete structures with difficult casting conditions. For such applications, the fresh concrete must possess high fluidity and good cohesiveness. The use of additive materials such as industrial wastes as mineral admixtures can ensure the required concrete properties. The initial experimental study aims at producing and evaluating SCC for ternary blends incorporating fly ash, GGBS, sugarcane bagasse ash and alccofine as partial replacement of cement. Five number of SCC mixes were investigated in this study. The self-compacting mixes have cement replacement with different percentages of mineral admixtures while keeping cement quantity fixed for 360kg/m3.The tests such as slump flow test, V funnel test, T500 slump flow test, J ring test and V5min test were carried on fresh properties of SCC mixes to check the prerequisites mentioned in EFNARC, the mechanical properties of hardened concretes such as compressive strength, split tensile strength were also carried on all the mixes. Incorporating these mineral admixtures resulted in producing economical concrete and the workability requirements of SCC were satisfied, the strength obtained was maximum when alccofine and GBBS were added in the concrete.

Analyze Portrayl of SEP for WSN Using Matlab
Wireless Sensor Networks (WSNs) are made out of heaps of sensor nodes, with restricted energy, that cooperates to perform a sensing project. In Wireless Sensor Network, the energy efficiency is the important thing difficulty for designing the protocol because sensor nodes have one-time battery backup. There are many cutting-edge protocols which increase the life of the wireless sensor Network through correctly the use of battery energy of the sensor node. In this research work, a brand new strategy and protocol based totally on Stable Election Protocol (SEP) in wireless Sensor network have been proposed. For proposed method, we've assumed heterogeneous environment i.e. the impact of heterogeneity of nodes, in terms in their strength, in wireless sensor networks which might be hierarchically clustered. In those networks, some of the nodes grow to be cluster heads, combination the records of their cluster members and transmit it to the sink. We count on that a percentage of the population of sensor nodes is ready with extra strength assets. We additionally anticipate that the sensors are randomly distributed and aren't cellular, the coordinates of the sink and the size of the sensor discipline are known. The uniqueness of the proposed method is that cluster head is chosen amongst normal Nodes, Intermediate Nodes and Advanced Nodes based upon their common strength. This assets will increase the number of cluster heads in keeping with spherical and number of packets per spherical. First of all the nodes had been labeled as everyday Nodes, Intermediate Nodes and advanced Nodes. Then, all three kinds of nodes are similarly categorized as Alive nodes and dead nodes. The cluster head is selected among all 3 types of nodes on the premise of average energy. Cluster head collects statistics from member nodes, mixture it and transmit it to the base station. Cluster head choice is maximum critical. Once the cluster head is selected then the cluster head broadcasts a commercial message to the nodes. The nodes get hold of the message and decide to which cluster head it is going to be long for the cutting-edge round. A Modified-SEP (proposed approach) has been applied and in comparison with existing SEP. Three parameters i.e. the number of dead nodes, the number of alive nodes and packets transmitted to base station and so forth has been taken as performance parameters. The simulation end result shows that overall performance and throughput of our proposed protocol deliver the effective and widespread power efficiency in addition to more Network lifetime as compared to different protocols. MATLAB R2013a has been taken as an implementation platform.

Safety Begins From Childhood
Every year, India experiences an unusually high number of fatalities caused by Head and Traumatic Brain Injuries (TBI). Of these, 65 to 70 % are caused in road mishaps. The balance are due to industrial accidents, War and Counter Insurgency Operations (CI Ops), Sports field Accidents, Domestic Violence, Riots, Natural Disasters and other acts of God including even an accidental fall. In 2015 alone, the number of officially recorded deaths was over 1,46,000, and injured with debilitating trauma was over half a million. This toll is growing at an alarming rate with no check or respite in sight. With one percent vehicles, India carries the burden of over 10 % deaths in the world and there is a traffic accident every minute and a death every 4 minutes. In the US, the fatality rate is one out of two hundred victims of road trauma and in India it is one in six. A majority of Head Injury victims are two wheeler riders and pedestrians, and unfortunately, we have come to be termed as the “Head Injury” Capital of the world. The victims in India are mostly in the age group of 18–44 years and are often, the only “Bread Winners” for a family of 4 to 6. A large number of survivors of such accidents sustain varying degrees of debilitating damage and require long term rehabilitation treatment. This is virtually non-existent in most parts of India, and where available, is highly expensive. In several cases, victims of TBI have to relearn to walk, talk and formulate thought from scratch. Even mild TBI leads to symptoms like decreased memory, insomnia, inability to focus, anxiety, mood swings, irritation, etc.

Qualitative Risk Assessment and HAZOP Study of a Glass Manufacturing Industry
In the recent years, many industries have realized that maintaining good occupational health and safety is as equally important in accordance to production requirement. Hence there has been much scope for the risk assessment in order to protect the workers’ health and safety at workplace. Risk assessment is a process where the Identified hazards are evaluated to determine the potential cause of an accident and further to reduce to the lowest reasonable risk level to protect worker’s health and safety. It is a part of risk management. Risk assessment can be categorized into Qualitative and Quantitative risk assessment which is being carried out using different techniques. In this paper, an attempt has been made to carry a Qualitative risk assessment i.e. Hazard Identification and Risk Assessment and HAZOP study for the identified critical areas of a glass manufacturing industry. From the results obtained from this study, Physical Hazard is 47%, Ergonomic Hazard is 10%, Chemical Hazard is 9%, Electrical Hazard 2%, Biological Hazard 3%, Thermal Hazard is 29% etc. Risks are also categorized into Low, Medium and High risks which 12.09%, 45.05% and 42.06% respectively. Hazard analysis from the design intent for Silane and ethylene gas station is also studied using a HAZOP technique. Some of the control valves are suggested to install before the gas filter. ALOHA is also used to simulate the model to analyse the impact due to leakage from the various potential hole area in the natural gas pipeline. Leakage from the larger hole of about 324.51 sq.cm has shown the high hazardous zone - death to human beings i.e.12m down the line in the wind direction. However, periodical maintenance and monitoring of the Natural gas distribution pipelines along with Gas detection system and fire hydrant system with sprinklers can prevent the disaster.
