Ref. No. 1 : EXPERIMENTAL STUDY OF CEMENT CONCRETE PREPARED WITH WASTE MARBLE POWDER
AUTHORS : Er. Vishendra Pund, Prof. Shailesh Kushwah , Prof. Kapil Soni
ABSTRACT : Durability in concrete production can be achieved by innovations in substitutions of material used. Innovations are much needed to meet the increasing demand for new and quality materials. Concrete is a construction material consisting of cementitious material, fine aggregate, coarse aggregate. Now a day’s marble has been widely used in structures. Marbles are used for the decoration purpose, which increases its demand in the market. Marble powder (MP) is a very fine powder, obtained as a by-product of marble during the sawing and the shaping, and not recycling it due to environmental problems in the world. Hence the reuse of waste material has been emphasized. One of the recent advancement in construction industry is replacement of materials in concrete. The replacement of materials offers cost reduction, energy savings and protection of environment. To achieve the above objective in this research work we have partially replaced the cement with waste marble powder produced from marble industries. This paper presents the feasibility of the substitution of waste marble powder for cement to achieve economy and environment saving. In this present investigation is focused to study the fresh and hardened properties of concrete when cement is partially replaced by waste marble powder. The work is focused on M20, grade of concrete with various percentage of waste marble powder that replaced cement in this investigation i.e., 0% as a control mix, 5%, 10%, 15% and 20% .The fresh proprieties are workability and hardened properties are compressive strength, split tensile strength, and flexural strength of concrete are at the curing age of 28days are to be determined. Then the various strength is compared with the conventional concrete.
Keywords: Environment, Waste marble powder, concrete, compressive strength, flexure strength, split-tensile strength, durability.
Ref. No. 2 : SMART HEALTHCARE MANAGEMENT SYSTEM USING IOT (INTERNET OF THINGS)
AUTHORS : Subodh Kumar , Lalit jain
ABSTRACT : IoT based smart architecture for automatic monitoring and tracking of patients, personnel,and biomedical devices within hospitals and nursing institutes. Staying true to the IoT vision,we propose a Smart Hospital System (SHS) which relies on different, yet complementary,technologies, specifically RFID, WSN, and smart mobile, interoperating with each other through a CoAP/6LoWPAN/REST network infrastructure. Smart health care, that measures users’ living conditions and health status using small sensing devices and collecting their data over a network under daily life, is expected as a new trend. It is getting paid more attention along with the increase of demands of preventive care. The architecture for this system is based on smart devices and wireless sensor networks for real time analysis of various parameters of patients. This system is aimed at developing a set of modules which can facilitate the diagnosis for the doctors through iot based -monitoring of patients. The goal of this pre dissertation was to produce a wireless patient monitoring system using iot over internet . Iot based patient monitoring systems are becoming increasing acceptable in today’s healthcare market, because of their low cost and easy adoption/integration features. A set of medical and environmental sensors are used to monitor the health as well as the surrounding of the patient. The doctors and care givers monitor the patient in real time through the data received through the server. The medical history of each patient including medications and medical reports are stored on cloud for easy access and processing for logistics and prognosis of future complications. The smart health care system is able to collect, in real time, both environmental conditions and patients’ physiological parameters via an ultra-low-power Hybrid Sensing Network (HSN) composed of 6LoWPAN nodes integrating UHF functionalities. Sensed data are delivered to a control center where an advanced monitoring application makes them easily accessible Ethernet net module .
Ref. No. 3 : A CASE STUDY OF STEAM TURBINE
AUTHORS: Bhupendra sahu, Shailesh Singh thakur
ABSTRACT: Steam turbine blades are one of the most critical components in power plants. Statistics has shown that LP blades are generally more susceptible to failure compared to blades in HP or IP turbines. The mechanism responsible for these failures is different and complex. A recent survey indicates that cause of over 40% of the blade failures is not fully understood. The two primary forces acting on the blades are the steady centrifugal forces due to rotation and the fluctuating steam bending forces. The paper is about a proposed innovative method of detecting the presence of blade vibration in operating turbine. The method is based on vibration analysis of the turbine casing. The casing vibration also includes the signals associated with the blade passing frequency (BPF) component. When the rotating blades vibrate, the analysis of changes in the BPF is a novel way of diagnosing blade vibrations. Signals captured from operating plants have been analysed and blade vibrations detected. Validation of the proposed technique through experiments demonstrates reliability of the technique as a robust diagnostics for turbine blades. The failure of a LP (low pressure) turbine blade of a 220 MW thermal power plant is presented. The blade was made of martensitic stainless steel and the structure was tempered martensite. There was no evidence of degradation of blade material. The fracture took place at the aerofoil region, 113-mm from the root. Throughout the blade surface Si rich phases were detected. Several pits/grooves were found on the edges of the blades and chloride was detected in these pits. These were responsible for the crevice type corrosion. The probable carriers of Cl were Ca and K, which were found on the blade. The failure mode was intergranular type. Possibly the ultimate failure was due to corrosion-fatigue. A gas turbine abruptly tripped to a stop during its daily morning start-up period. Out of a total of 81 blades in the first row only one blade was broken at its root. Prior to this accident, there were three blade failure accidents in the same plant during the last 10 years. First, the fracture surface of the troubled blade was investigated. Stress analysis of the blade showed that the maximum stress occurred due to the pressure profiles developed during operation. Modal analysis for one blade and the assembly of blades was performed and Campbell diagram and Interference diagram were drawn to check the dynamic characteristics of the blades. The vibration of the turbine was measured using accelerometers during the operation condition. The result shows that the fatigue fracture of
the blade was originated during transient events internal to the combustion chamber which was close to the resonance condition of the assembled blades.
Ref. No. 4 : A CASE STUDY ON PERFORMANCE EVALUATION OF COOLING TOWERS IN THERMAL POWER PLANT
AUTHORS : Vivek Kumar Dewangan, Shailesh Singh thakur
ABSTRACT : Cooling tower spray nozzle performance characteristics such as the water distribution onto the fill material, air side pressure drop, pump head, drop size distribution and heat transfer in the spray zone were investigated experimentally and theoretically. The aim was to evaluate and simulate the performance characteristics of new and existing types of cooling tower spray nozzles with emphasis on the spray zone. Two medium and two low pressure type spray nozzles were tested and the results analyzed. Single nozzle water distribution data obtained from tests was used to predict the water distribution obtained from four evenly spaced nozzles by superposition. The results were compared to data obtained from corresponding four nozzle tests. Computer codes and CFD models were developed to predict the drop trajectories, water distribution, total heat transfer and pressure drop for single nozzles and four nozzle grids. This was compared to correlated data found in literature. The performance characteristics expected from an ideal nozzle was discussed and compared to actual nozzle performance characteristics.
Ref. No. 5 : Optimal Placement of Distribution generation unit within a radial distribution system using Multi‐Objective Genetic Algorithm
AUTHORS : Lokendra Singh, Prof. Siju George, Dr. A.A. Ansari
Abstract— An electric power distribution system is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Radial distribution system is arranged like a tree where each customer has one source of supply. The optimal placement of Distributed Generation (DG) has attracted many researchers’ attention recently due to its ability to obviate defects caused by improper installation of DG units, such as rise in system losses, decline in power quality, voltage increase at the end of feeders and etc. Tail End Node Voltage Deviation Index only give voltage deviation of tail end nodes, but if we want to optimize the overall distribution system, the voltage profile of whole network should consider along with power loss reduction factor.
This Research Synopsis proposes a Multi-objective genetic algorithm for optimal placement of DG within RDS by considering overall voltage, tail-end voltage, power loss and other parameters as an objective function. The outcome indicate that the proposed optimization algorithm improves the accuracy of the solution and is considerably faster than other techniques and, is capable of escaping from local minima and finding the global one effectively.

Ref. No. 6 : A CASE STUDY OF BIODIESEL AS AN ALTERNATIVE IN DIESEL ENGINE
AUTHORS : Ravi Tripathi, Shailesh Singh thakur
ABSTRACT: The true fact that everyone has to accept for search of alternative fuels apart from petroleum products is biodiesel for many reasons, mainly increasing demand and scarcity of petroleum products and to preserve the wealth of nature to be used for coming generations. The reason of non implementation of biodiesel in day-to-day life is because of few limitations. Many scientists are in progress for a new dimension of research in biodiesel plantation, cultivation and its usage in engines. This paper highlights the importance of biodiesel production techniques such as supercritical methanolysis, ultrasonication method and microwave technique by which maximum biodiesel can be produced. The new approach of using nano particle in biodiesel shows very good results in reducing the level of pollutant gases in the engine exhaust and increased performance without any engine modification is also discussed briefly in this case study.
Keywords––Hydrodeoxygeneration, nano particle, ultrasonication, microwave technique
Ref. No. 7 : BUILDINGS WITH STRUCTURAL MANSONRY WALLS CONNECTED TO TIE‐COLUMNS AND BOND‐BEAMS
AUTHORS : Shubhank Anubhav paul, Prof. Rahul Rathore
ABSTRACT : Confined masonry is extensively used in seismic regions around the world. Experimental data about confined masonry are very scarce and this lack of knowledge affects the seismic safety and the design practice of masonry structures. This type of constructions consist basically of masonry panels confined by vertical and horizontal elements usually of reinforce concrete. This confinement enhances greatly the connection between structural walls, improves the stability and the strength, provides ductility under earthquake loading and improves the integrity and containment of earthquake damage in masonry walls.
The present dissertation concerns a general review on confined masonry structures, ranging from current and past research, taking as a reference the experimental data available in the literature. Failure and resisting mechanisms are described. Vulnerability and experimental tests in confined masonry are presented as well. Finally some code recommendations, of different countries, for a proper construction and resistance verification are given.
Keywords: confined masonry; tie-columns; bond-beams; failures modes; resisting mechanisms

Ref. No. 9 : A DETAILED STUDY OF CEMENT CONCRETE PREPARED WITH WASTE RICE HUSK ASH (RHA)
AUTHORS : Ms. Zeba Khatoon, Prof. Shailesh Kushwah , Prof. Kapil Soni
ABSTRACT: The innovation of concrete can reduce the consumption of natural resources and energy sources and decrease the burden of pollutants on environment. In the last decade, the use of supplementary cementing materials has become an integral part of high strength and high performance concrete mix design. These can be natural materials, byproducts or industrial wastes, or the ones requiring less energy and time to produce. One of the commonly used supplementary cementing material is Rice Husk Ash (RHA). Rice Husk Ash (RHA) is an agricultural waste product which is produced in large quantities globally every year and due to the difficulty involved in its disposal, can RHA becoming an environmental hazard in rice producing countries.It is most essential to develop ecofriendly concrete from RHA. RHA can be used in concrete to improve its strength and other durability factors. This paper presents an overview of the work carried out on the use of RHA as partial replacement of cement in concrete. Reported properties in this study are the mechanical, durability and fresh properties of concrete.In the present investigation, a feasibility study is made to use Rice Husk Ash as anpartial replacement to Cement in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive, Split and Flexural). For control concrete, IS method of mix design is adopted and considering this a basis, mix design for replacement method has been made. Five different replacement levels namely 0 % (as a control), 10%, 20%, 30% and 40% are chosen for the study as concern to replacement method.

Ref. No. 10 : Review: Worm Hole Detection & Prevention in Order to Increase Network Security in Mobile Ad-hoc Network
AUTHORS :Akansha Panse, Anurag Jain
ABSTRACT:Mobile ad-hoc network (MANITs) is one of the most vibrant field among different wireless communication network technologies. MANITs can replace wireless infrastructure network. Self-organization, self-configuring and self-healing natures of MANITs dynamically provide solution for high-speed internet access. MANITs are highly cost-effective and provide scalability and flexibility. As a result of its open medium nature, distributed architecture and dynamic topology, it is highly prone to security vulnerability. Wormhole attack is the most vulnerable attack in MANITs, where two malicious nodes at different locations establish a tunnel between them and can selectively drop data packets. Detection and prevention of wormhole attack is very difficult. This paper gives a brief introduction of Mobile ad-hoc network, security challenge and different type of attack over MANET also link wormhole as a serious thread that is successfully isolated from the concerned network.
