Title : A Study on Scenarios for Derivation of Emergency Recovery Method of Waterfront Structures Authors : Hyuk-Jin Yoon, Sang-Jae Han, Jae-Hyun Jung
Abstract : Civil engineering structures constructed on rivers are placed in an environment exposed to frequent flood damages. Since the loss of levee due to flood and bridge scour are major causes of sudden structural collapse, emergency recovery construction must be quickly carried out before long-term recovery.
This study refers to the relevant rules and practices for types of damage caused by bridge scour and loss of levee due to flood, preparing flowcharts for quick selection of emergency recovery process and deriving decision-making trees. The characteristics of the decision-making trees derived applied variable considerations on changes in the standards, addition of construction methods, and addition of examples.

Title : Improvement of Distortion Power Quality Index in Distributed Power Grids Authors : P.Emmaniyelu, A.Tejasri
Abstract : This paper presents the Euclidean norm based new power quality index (PQI), which is directly related to the distortion power generated from nonlinear loads, to apply for a practical distribution power network by improving the performance of the previous PQI proposed by the authors. The proposed PQI is formed as a combination of two factors, which are the electrical load composition rate (LCR) and the Euclidean norm of total harmonic distortions (THDs) in measured voltage and current waveforms.
The reduced multivariate polynomial (RMP) model with the one-shot training property is applied to estimate the LCR. Based on the proposed PQI, the harmonic pollution ranking, which indicates how much negative effect each nonlinear load has on the point of common coupling (PCC) with respect to distortion power, is determined. Its effectiveness and validity are verified by the experimental results from its prototype’s implementation in a laboratory with a single-phase 3 kW photovoltaic(PV) grid-connected inverter, which contributes to a small distortion in voltage at the PCC, and practical nonlinear loads. Then, the harmonic current injection model based time-domain simulations
are carried out to prove the effectiveness of the proposed PQI under the other conditions with different nonlinear loads.

Title : Coordination of Multiple Renewable Generators Used in a Micro grid Based on Distributed Sub gradient Authors : K.Ramu, A.Tejasri
Abstract : Maximum peak power tracking algorithms, which emphasize high renewable energy utilization, may cause a supply-demand imbalance when the available renewable generation is more than demanded, especially for autonomous microgrids. Currently, droop control is one of the most popular decentralized methods for sharing active and reactive loads among the distributed generators. However, conventional droop control methods suffer from slow and oscillating dynamic response and steady state deviations. To overcome these problems, this paper proposes a distributed sub gradient-based solution to coordinate the operations of different types of distributed renewable generators in a microgrid. By controlling the utilization levels of renewable generators, the supply-demand balance can be well maintained and the system dynamic performance can be significantly improved. Simulation results demonstrate the effectiveness of the proposed control solution.

Title : Decision Support Tool for Selecting Appropriate Sustainable Rainwater Harvesting Based System in Ibadan, Nigeria Authors : Omolara Lade, David Oloke
Abstract : The approach to water management worldwide is currently in transition, with a shift from centralised infrastructures to greater consideration of decentralised and sustainable technologies, such as rainwater harvesting (RWH). However, in Nigeria, implementation of sustainable water management, such as RWH systems, is inefficient. Social, environmental and technical barriers, concerns and knowledge gaps exist, which currently restrict its widespread utilisation. This inefficiency contributes to water scarcity, water-borne diseases, and loss of lives and property due to flooding. Meanwhile, several RWH technologies have been developed to improve sustainable water management (SWM) through both demand and storm-water management. Such technologies involve the use of reinforced cement concrete (RCC) storage tanks, surface water reservoirs and ground-water recharge pits as storage systems for mitigating water supply problems in Ibadan. A framework was developed to assess the significance and extent of water management problems, match the problems with existing RWH-based solutions and develop a robust ready-to-use decision support tool that can quantify the costs and benefits of implementing several RWH-based storage systems. The methodology adopted was the mixed method approach, involving a detailed literature review, a questionnaire survey of relevant stakeholders such as: household respondents, Nigerian Architects and Civil Engineers and focus group discussion were also conducted. 18 selection attributes have been defined and three alternatives have been identified in this research. The questionnaires were analysed using SPSS, Excel and selected statistical methods to derive weightings of the attributes for the tool. Following this, three case studies were modelled using RainCycle software. From the results, the MDA model chose RCC tank as the most appropriate storage system for RWH.

Title : Shear Strengthening of Reinforced Concrete Beam Using High Density Polyethylene (HDPE) Laminate – A Review Authors : Aruldasu M, Sridhar J, Arulkumar M
Abstract : The issue of upgrading and repair of existing civil engineering infrastructure has been one of great importance for over a decade. Deterioration of bridge decks, beams, girders and columns, buildings, parking structures and others may be attributed to several factors such as ageing, environmentally induced degradation, poor initial design and construction and lack of maintenance. In many cases, retrofit and rehabilitation by conventional means is very costly since it calls for specialized equipment and the shutdown of the structure during repair. In this report, results of an ongoing research program aimed at investigating alternative methods for strengthening and repairing concrete structures will be presented. However, structural performance is comparable and is superior to panels produced using hand lamination.
In this sense, the aim of the present study, is to evaluate the contribution of the external reinforcement of concrete beams, reinforced by High Density Polyethylene (HDPE) laminates. An experimental program on a total of five concrete beams reinforced by various hybrid configurations of reinforcement tested up to 75% failure under a static loading in two points bending, to determine the best combination of the strengthening scheme.
This report reviews eighteen articles on RC beams strengthened with HDPE. Finally, this report attempts to address an important practical issue that is encountered in strengthening of beams with different type and different thicknesses of fibre reinforced polymer laminate.

Title : A REVIEW ON 2 STROKE ENGINE Authors : Ayush Gupta, Akshay Bedi
Abstract : Two-stroke engines have dropped out of the automobile market for a long time due to severe drawbacks. Unfortunately, the comparison with the performances of four-stroke engines was not in favour of two-stroke ones. Nevertheless, the needs of a [4] more compact engine with a better ratio of the mass and size versus power motivated research efforts at the beginning of the 90s. Regrettably, these efforts did not result in commercial success and automobile manufacturers kept four-stroke engine architecture as base architecture.
However, the two-stroke engine is a highly favourable concept for downsizing and cost reduction by reducing the number of cylinders without NVH penalties. All that added to the maturity of CFD calculations and the availability of high power electronic for control and fuel injection encouraged the Renault research division to have a closer look into its architecture.

Title : A REVIEW ON 4 STROKE ENGINE Authors : Ayush Gupta, Akshay Bedi
Abstract : Today, internal combustion engines in cars, trucks, motorcycles, aircraft, construction machinery and many others, most commonly use a four-stroke cycle. The four strokes refer to intake, compression, combustion (power), and exhaust strokes that occur during two crankshaft rotations per working cycle of the gasoline engine and diesel engine.
The cycle begins at Top Dead Center (TDC), when the piston is farthest away from the axis of the crankshaft. A stroke refers to the full travel of the piston from [1] Top Dead Center (TDC) to Bottom Dead Center (BDC). (See Dead centre.)
1. INTAKE stroke: On the intake or induction stroke of the piston , the piston descends from the top of the cylinder to the bottom of the cylinder, reducing the pressure inside the cylinder. A mixture of fuel and air is forced by atmospheric (or greater) pressure into the cylinder through the intake port. The intakevalve(s) then close.
2. COMPRESSION stroke: With both intake and exhaust valves closed, the piston returns to the top of the cylinder compressing the fuel-air mixture. This is known as the compression stroke.
3. POWER stroke.: While the piston is close to Top Dead Center, the compressed air–fuel mixture is ignited, usually by a spark plug (for a gasoline or Otto cycle engine) or by the heat and pressure of compression (for a diesel cycle or compression ignition engine). The resulting massive pressure from thecombustion of the compressed fuel-air mixture drives the piston back down toward bottom dead center with tremendous force. This is known as the powerstroke, which is the main source of the engines torque and power.
4. EXHAUST stroke.: During the exhaust stroke, the piston once again returns to top dead center while the exhaust valve is open. This action evacuates the products of combustion from the cylinder by pushing the spent fuel-air mixture through the exhaust valve(s).

Title : BUCKLING ANALYSIS OF CYLINDRICAL SHELL STRUCTURES USING FINITE ELEMENT ANALYSIS Authors : Neelesh Ashok, Ben Austin B Alapatt
Abstract : Thin shell structures find wide applications in many branches of engineering. Examples include aircraft, space shuttles, launch vehicle tankages, pressure vessels, pipelines etc. The design involves the determination of stresses and deformations produced by imposed loads on the structure. The structure is subjected to buckling, a physically observed failure mode that is associated closely to load carrying capacity, when it is in service. The buckling strength of thin walled cylinders are to be determined and depending upon the material and geometry, the compressive stresses may lead to any of the failure modes like elastic buckling, elastic plastic buckling and plastic collapse. The purpose of this work is to review the entire field of buckling of cylindrical shell structures to find the allowable stress and deformation under given load which is primarily accomplished by referring to reviews, scholarly articles, journals, books and study the load carrying capacities of shells under different loading mechanisms like torsion, axial compression and uniform lateral external pressur.

Title : WIRELESS MONITORING AND CONTROLLING SYSTEM USING CYBER SENSOR NETWORK FOR INDUSTRIAL APPLICATIONS Authors : C.MARAGATHAM, DR.C.N.MARIMUTHU
Abstract : The expanding reach and wide deployment of digital systems into our most fundamental physical infrastructures pose both a complexity and security concern. The complexity of modern industrial networks primarily stems from three areas: presence of heterogeneous hardware and software, dynamic network composition and usage patterns, and decentralization of control. Dealing with these complexities requires a solution that is flexible and manageable.In existing system, industrial data’s are only monitoring through WAN using SOAP and IF-MAP protocol in software manner. But data monitoring is not enough because in critical time admin should have rights to control the industrial data’s to avoid the accidents and production wastage.In proposed system, we are using both hardware and software manner. Here SOAP protocol is used in hardware part detects the sensor values through WSN system. IF-MAP is used in software part for data sharing and security purpose for WAN. D-bus is used to link the hardware and software parts. Using this system we can monitor and control the entire industrial system. Here mainly industrial parameters are controlled through WAN.

Title : Handshaking (Flow control) and Arbitration (Output control) Mechanism for Network on chip (NoC) Routers Authors : Purva Dave (Shrimali), Kapil Kumawat
Abstract : In this article, designing and implementation a NoC router based on handshaking communication protocol and Arbitration/Output control mechanism are presented. The advent of deep sub-micron technology has recently highlighted the criticality of the on-chip interconnects. As diminishing feature sizes have led to increases in global wiring delays, Network-on-Chip (NoC) architectures are viewed as a possible solution to the wiring challenge and have recently crystallized into a significant research thrust. Both NoC performance and energy budget depend heavily on the routers buffer resources. This paper introduces a novel unified buffer structure, called the dynamic Virtual Channel Regulator (ViChaR), which dynamically allocates Virtual Channels (VC) and buffer resources according to network traffic conditions. ViChaR maximizes throughput by dispensing a variable number of VCs on demand. ViChaRs ability to provide similar performance with half the buffer size of a generic router is of paramount importance, since this can yield total area and power savings of 30% and 34%, respectively, based on synthesized designs in 90 nm technology. This paper presents Virtual Ring Routing (VRR), a new network routing protocol that occupies a unique point in the design space. VRR is inspired by overlay routing algorithms in Distributed Hash Tables (DHTs) but it does not rely on an underlying network routing protocol. It is implemented directly on top of the link layer. VRR provides both traditional point-to-point network routing and DHT routing to the node responsible for a hash table key. It performs comparably to, or better than, the best wireless routing protocol in each experiment. VRR performs well because of its unique features: it does not require network flooding or translation between fixed identifiers and location dependent addresses.
