STRUCTURAL REHABILITATION OF BEAMS WITH STEEL FIBRE REINFORCED UHSC STRIPS

Authors:Dr.Anuradha. R, John Britto.X

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/01-04

ABSTRACT
Reinforced concrete structures show excellent performance in terms of structural behavior and durability except for those zones that are exposed to severe environmental influences and high mechanical loading. Rehabilitation of deteriorated concrete structures is a heavy burden from the socio-economic viewpoint since it leads to significant user costs. As a consequence, novel concepts for the rehabilitation of concrete structures must be developed. Sustainable concrete structures of the future will be those requiring just minimum interventions of only preventive maintenance with no or only little service disruptions. Over the last 10 years, considerable efforts to improve the behavior of cementations materials by incorporating fibres have led to the emergence of Steel Fiber Reinforced Ultra-High Strength Concrete (SFRUHSC). These novel building materials provide the structural engineer with a unique combination of extremely low permeability which prevents the ingress of detrimental substances such as water and chlorides and very high strength, i.e., compressive strength higher than 100 MPa, tensile strength higher than 10 MPa and with considerable tensile strain hardening and softening behaviour. Consequently, SFRUHSC have improved resistance against severe environmental influences and high mechanical loading thus providing a potential to significantly improve structural resistance and durability to concrete structures. The basic conceptual idea is to use SFRUHSC in those zones of the structure where the outstanding SFRUHSC properties in terms of durability and strength are fully exploited; i.e. SFRUHSC is used to “harden” the zones where the structure is exposed to severe environmental conditions (eg., deicing salts, marine environment) and high mechanical loading (eg., impact, concentrated loads, fatigue). All other parts of the structure remain in conventional structural concrete as these parts are subjected to relatively moderate exposure. This concept necessarily leads to composite structural elements combining conventional reinforced concrete and SFRUHSC. The combination of the SFRUHSC protective and load carrying properties with the mechanical properties of steel reinforcement bars (denominated reinforced SFRUHS) provides a simple and efficient way of increasing the stiffness and load-carrying capacity while keeping compact cross sections. This concept may be applicable for old as well as new structures and the SFRUHSC strip may be precast or cast in-situ.

Authors: Shankar R, John Wiselin, Divya Selvathurai

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/05-12

ABSTRACT
A new design methodology of Class E power amplifier is proposed in this paper which operates to broadband range of 6.78MHz-2.45GHz. The Broadband model is accomplished by high power and low power transistor. The Efficiency of the power amplifier is increased by increasing the order of the input and output matching network. A GaN-HEMT transistor is used for the high power, which is carefully modelled and characterized to prescribe the optimal output impedance for the broadband Class-E operation. GaAs HBT is used for low power design. The circuits are simulated using Advanced Design Systems (ADS-2011).

ABSTRACT
In countries where the economic status is poor, it becomes crucial for those concerned with developmental policies to adopt appropriate strategies which will ensure that every single unit of money available is used to develop the country in those fields to facilitate a conductive environment for economic development. Road traffic accidents have been recognized as one of the adverse elements which contribute to the suffocation of economic growth in the developing countries, due to the high cost related to them, hence causing social and economic concern. So Traffic safety is an important key and play an integral role in sustainable transportation development. Now days, the main negative impacts of modern road transportation systems are injuries and deaths in road accidents. The success of traffic safety and highway improvement programs hinges on the analysis of accurate and reliable traffic accident data. This study discuss the present state of traffic accident information on NH 47 Gandhipuram to Avinashi and NH-209 from Gandhipuram to Annur, Coimbatore District. It shall also discuss the Identification of high rate accident Locations by using GIS Software and safety deficient areas on the highway. Remedial measures and provisions for traffic safety are suggested for reducing the risk of accidents in blackspots.

Authors: J Sahaya Ruban & N Sakthieswaran

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/17-18

ABSTRACT
This study investigates the effect of the addition of steel and treated coir fibers on the mechanical properties of concrete. Steel fibers and coir fibers were used at five different fiber volume fractions of 1.0%, 1.5%, 2%, 2.5% and 3% at equal proportions. All the fiber-reinforced concretes contained 10% silica fume as a cement replacement and 40% copper slag as a sand replacement. The compressive strength, splitting tensile strength, flexural strength, of the concrete mixes was examined. Results of the experimental study indicate that addition of silica fume and copper slag improves the mechanical properties of concrete. Furthermore, it was observed that the addition of 3% steel fiber significantly enhanced the splitting tensile strength and flexural strength of concrete. Among different combinations of steel and coir fibers investigated, the best performance was attained by a mixture that contained 3% steel and 3% treated coir fiber.

FIREFLY ALGORITHM APPLIED FOR OPTIMAL REACTIVE POWER DISPATCH

Authors: R. Suresh, J. Baskaran

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/19-23

ABSTRACT
Optimal reactive power flow is a special case of optimal power flow (OPF) problems. Optimization of reactive power dispatch (ORPD) is necessary for secured operation of a power system. Real power loss is minimized for achieving ORPD. Generator bus voltage magnitudes, transformer tap settings and VAR outputs from shunt compensating devices are the control parameters in ORPD. These control parameter values are adjusted for loss reduction. In this work, the newly introduced firefly algorithm is proposed for finding suitable values of the control parameters that optimizes ORPD. The firefly algorithm is based on the flashing characteristics of fireflies. The algorithm has less number of operators and can be easily implemented for any optimization problems. The proposed algorithm tested on an IEEE 30 bus system and the results are obtained.

OPTIMIZATION OF REACTIVE POWER FLOW – PERFORMANCE COMPARISON OF GSA AND BB-BC ALGORITHMS

Authors: R. Suresh, J. Baskaran

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/24-29

ABSTRACT
Optimal Reactive Power Flow (ORPF) problem is a multi-constrained, multi-objective problem which optimize the secured operation of a power system by minimizing real power loss and voltage deviation. The minimization of both real power loss and voltage deviation at the load buses by controlling the reactive power is termed as Optimal Reactive Power Dispatch (ORPD) which also improves the voltage profile in the system. Generator bus voltage, transformer tap position and shunt VAR compensator settings are taken as design variables in optimizing reactive power flow. ORPD is achieved in the ORPF problem by using artificial intelligence techniques. The newly proposed algorithms like Big Bang – Big Crunch algorithm and Gravitational Search Algorithm reduces the objective functions more efficiently and effectively than the conventional methods. The algorithms are simple and easy to implement for engineering optimization tasks. These two algorithms are used for reactive power optimization by controlling the design variables. The proposed method is tested using IEEE 30 bus system.

DESIGN AND ANALYSIS OF DISTRIBUTED POWER FLOW CONTROLLER WITH IMPLEMENTATION OF PI CONTROLLER

Authors: K. Kirubananthan, T.S. Sivakumaran

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/33-37

ABSTRACT
This paper presents a concept of a distributed power flow controller (DPFC). The DPFC is derived from the unified power flow controller (UPFC). The DPFC can be seen as a UPFC with an eliminated common DC link. The cost of the DPFC is also much lower than the UPFC because no high-voltage isolation is required at the series converter part and the rating of the components of is low. The DPFC works the distributed FACTS (D-FACTS) concept, which is to use multi small-size single-phase converters instead of the one large-size the three-phase series converter in the UPFC. A large number of series converters provides redundancy, thereby increasing the system reliability. The DPFC has the similar control capability as the UPFC, which involves the adjustment of the line impedance, the transmission angle, and the bus voltage. The principle and analysis of the DPFC are presented in this paper and the corresponding simulated results that are carried out using Matlab/ Simulink platform.

Authors: Arulananth.T.S, Jayasingh .T, Gangatharan. N, Baskar.M

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/66-70

ABSTRACT
Face detection and recognitions has an important role in cyber and surveillance and patient monitoring system and implementation constraints limit their performance. Face images are captured from a distance, and the identification does not require interaction with the subject. Similarly, sliced video inputs has received much attention due to its ability to preserve data privacy and still support indexing, searching, mining and other required operations (essential to medical domain). In this context, in this research work, novel algorithms interleaved with h sliced algorithm are presented with focus on faster retrieval schemes to suit real time implementation. This proposed work is applied to patient monitoring systems to detect backward and forward fall of patients in hospitals. Pose variation creates an artifact in face detection and recognition. This effect is taken care to detect the images and recognizes the correct image even with changes in the posture. The new algorithm was, on average, able to detect backward falls prior to impact, with 95% sensitivity, 90% specificity and 255 ms response time. Hence, it is concluded that the fall detection algorithm detect falls during motion and is suited for the elderly population. To realize the fall detection algorithm, the angles acquired by the sensors are used the system inputs and a real time system on Linux OS is developed to process and make a detection quickly. To make the system scalable and ported with minimum memory requirement, dimensional reduction algorithm (PCA based) intrinsically Coexist. The real time systems generate an ordered feature sequence and then examined in a sequential manner by the proposed nonlinear classifier for recognition purpose.

Authors: Jebakani, D, Krishnaveni, A, Pitchipoo, P. and Jeyakumar, K

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/92-101

ABSTRACT
This paper investigates the multi-criteria optimization of gas metal arc welding (GMAW) process for better parametric combination to yield good mechanical strength of welded joints using hybrid grey relational analysis. The strength of welded joints in GMAW depends on several input process parameters such as wire speed, travel angle, arc voltage, contact tip to work distance, work angle and gas flow rate. There is a need to control the process parameters to obtain good quality welded joints. Hybrid grey relational analysis (HGRA) method was proposed to predict parameters that resulted in the best mechanical properties. The predicted parameters were used to produce specimens that were tested and were found to have the best combination of tensile strength, impact strength, and hardness. Thirty six experimental runs based on an L36 orthogonal array of Taguchi method were performed to derive objective functions to be optimized within the experimental domain. Entropy measurement method is used to determine the weights of the output responses. It is concluded that wire speed, voltage and distance between contact tip to work are the significant parameters and the others have less influence to get better mechanical strength in the GMAW process.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/102-107

ABSTRACT
An environmental concern and accessibility of gasoline fuels include caused interests in the explore for alternate fuels for internal combustion engines. Waste plastics are essential materials in the current world and purpose of industrial field is continually increasing. As an alternative, non-biodegradable, and renewable fuel, waste plastic oil (WPO) is receiving in-creasing notice. The LHR with waste plastic oil was compared with the petroleum products and found that it can also be used as fuel in compression ignition engines. In this current work, the piston was modified with LHR coating i.e partial stabilized zirconium (PSZ) in a single cylinder four strokes, diesel engine has been experimentally investigated using waste plastic oil as a fuel. The experimental result shows that the emissions like carbon monoxide and unburned hydrocarbons were slightly lesser than that of the conventional diesel engine. The carbon dioxide emission of waste plastic oil was slightly higher than diesel. Brake thermal efficiency increases with 30% to 34% in waste plastic oil with LHR at all load conditions.

Authors: M. Balamurugan, T.S. Sivakumaran

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/108-113

ABSTRACT
Dynamic Voltage Restorers (DVRs) are tied to the power grid through power-frequency transformers. In this study, the design of Diode Clamped Multilevel Inverter based dynamic voltage restorer (DVR) is presented and offered to perform the fast fault detection. A novel control method for DVR is aimed with a carrier modulated PWM inverter. The proposed control system is simple to design and has excellent voltage compensation capabilities. The suggested method for voltage sag/swell detection can detect different forms of power disturbances faster than conventional detection methods. To obtain acceptable properties such as transient overshoot, setting time, and steady-state error. By this, it is expected that the result of disruptions on the output of proposed DVR could be contracted for both symmetrical and asymmetrical voltage sag conditions using MATLAB/ Simulink software. To reduce power interruptions, this study offers a new Zeta converter based DVR system. This proposed strategy can quickly access the voltage sag and swell under transient condition.

EXPERIMENTAL AND THEORETICAL STUDIES ON UN-PLASTICIZED POLY VINYL CHLORIDE (UPVC) PIPE BURIED IN COHESIONLESS BACKFILL

Authors: Nirmala R., Rajkumar R., Akkineni Surya Teja.,Vignesh Bharathy K.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/122-125

ABSTRACT
Buried conduits act as an important life-line structure of the modern world. These conduits have undergone a stride of changes over the years. However the theories used for the design of these pipes have not been updated to suit the modern polyvinyl pipes. The use of these equations to design the plastic pipes have resulted in certain failures and in some cases a suboptimal design. The testing of UPVC pipes was done using a soil box facility for different soil covers with and without geogrids for incremental loading using hydraulic jack under loose soil conditions. The test results indicate that diametric strain in pipe increases with decrease in soil cover and the use of geogrids to reduce the diametric strain is effective at shallow depths and their effectiveness decreases with increase in soil cover. The comparison of diametric strains with that of theoretical deflections calculated using spangler and greenwood and lang theory shows that the classical approach of spangler provides an over all safe design for the buried flexible plastic pipes.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/142-145

ABSTRACT
Most important influencing factors of their practical performance, increasing of applications and also qualitative surface finish, the particle reinforced aluminium matrix composites (PRAMCs) were preferred. The components formed through high speed milling with the corresponding feed rate and depth of cut. Particle reinforced aluminium matrix composites have significant warmth due to their splendid mechanical properties like high hardness, high tensile strength etc. This paper presents an efficient investigation of effective stress in high speed milling of Al 6061/SiC/Zn and Al 7075/SiC/Zn by high speed steel (HSS) tools. The influences of cutting parameters on Surface roughness (Ra) and Effective stress (Es) were investigated. The simulation results are also carried out on AA 6061 and AA 7075 alloys to deliver the valuable influence of the reinforcements. In this research work the experimental results were revealed that the milling speed and the feed rate are the most momentous milling parameters for surface roughness. In addition the depth of cut influences more on effective stress and deflection by milling speed and feed rate. The experimental procedure confirmed that the improvement of surface roughness based on feed rate and speed. In feed direction the effective stress was calculated and the results are compared with the predicted values through Deform 3D simulations. Finally the comparisons of overall performance were made between both Metal Matrix Composites.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/146-157

ABSTRACT
System concept is employed in planning to overcome inadequacy of traditional methods in addressing increasingly complex problems, which require holistic approach, and where emphasis is put mainly on interrelationships of individual subsystem within the system by various Scholars. In this present research, System Dynamic models for various subsystems were developed by employing STELLA software 9.1.4 Version, to recognize the functions of the system. An integrated System Dynamic model for energy efficient sustainable development was developed to look at the dynamic functions, under different alternative conditions. The validated model has been employed to project the control parameters, which decide the functions of the system and thereby developed the projected year model for the year 2041 A.D. Further, alternative plausible scenarios were developed and tested in the forecasted year model 2041 A.D., by employing simulation techniques for arriving at plausible decisions. The results of optimal scenario chosen were analyzed, and recommended for the sustainable development of the system to evolve plausible policy planning guidelines.

GREY WOLF OPTIMIZER FOR ECONOMIC LOAD DISPATCH WITH VALVE POINT LOADING

Authors: *G.R.Venkatakrishnan, J. Mahadevan, R.Rengaraj

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/158-163

ABSTRACT
Economic load dispatch (ELD) is one of the most important optimization problems in the modern power system. The introduction of non-convex, non-differentiable and non-continuous models like valve point loading (VPL) and prohibited operating zone (POZ) makes the conventional ELD problem to a highly non-linear constrained problem which makes the conventional method to stick to local optima. In this paper, grey wolf optimization (GWO) algorithm which inherits the social and hunting behavior of grey wolves is used to solve such non-linear, non-convex ELD problem. The effectiveness of the GWO algorithm is verified by testing it on two ELD problems with VPL. The performance of GWO algorithm is validated using the statistical measures like minimum, maximum, mean and standard deviation over 50 independent test runs. Comparative results reveal that GWO algorithm for the chosen non-linear ELD problem performs better in terms of solution quality and robustness.

Authors: *D.Priya, J.Arunarasi, S.Leo Pauline, J.Jenisha

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/164-167

ABSTRACT
The (CMPs) chip multi processors is considered by uniform cache access (UCA) architecture. As cache become larger and also partitioned into multiple banks. Increasing wire delay makes it difficult to provide uniform access latencies to all L2 cache banks. In order to reduce the cache memories and wire delay the NUCA architecture has been implemented. By monitoring the NUCA architecture, we can allow nearer cache banks to have lower access latencies than further banks, which analogously increases the memory and time consumption based on both SRAM and MRAM memory and also power consumption criteria. NUCA architecture was initially proposed for uniprocessor system( ie large L2 cache). In this project, Xilinux software was simulated and results were obtained for S-NUCA-1 vs S-NUCA-2 and D-NUCA. And comparison results shows between S-NUCA-1 and D-NUCA architecture.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/174-178

ABSTRACT
A mobile ad hoc network (MANET) enables wireless communications between participating mobile nodes without centralized administration. Two nodes that are out of one another’s transmission range need the support of intermediate nodes, which relay messages to set up a communication between each other. The broadcast operation is the most fundamental role in MANETs. In on-demand route discovery, Simple flooding is widely used, where each node blindly rebroadcast the received RREQ till appropriate route to destination is accomplished Where each node forwards the packet once and only once, makes every node a forwarding node. If the forwarding nodes are not carefully designated, they will trigger many retransmissions at the same time, which might congest the network. It aggravates a high number of unnecessary packet rebroadcasts, causing contention, packet collisions and broadcast storm problem, which has been shown to greatly increase the network communication overhead and end-to-end delay. The performance degradation of such problems can be reduced if measures are taken during the dissemination of RREQ packets. Efficient broadcasting method can reduce the number of rebroadcasting, therefore reduce the chance of contention and minimize the collision among neighbouring nodes. We introduce a new probabilistic approach for route discovery, that is simple to implement and can significantly reduce the overhead related with the dissemination of RREQs. Simulation results shows this on demand probabilistic route discovery performs well and can result in significant reduction of control overhead while achieving increased throughput, packet delivery ratio and reduced delay compared with AODV and DSDV.

ABSTRACT
The necessity to increase the quality of a product has been gaining wide significance with new methodologies aiming to increase the efficiency of the existing quality enhancing methodologies. A major attribute to quality enhancement is the ability to detect fault prone modules in the developed system. The proposed work exploits the relationship between object oriented metrics (OOM) and the fault proneness of the design system in an empirical manner. The prominent design metrics may be cohesion, inheritance, coupling etc. Two aspects of fault prediction have been investigated in the proposed work. A statistical prediction for classifying faults and conceptuality to relate fault with classes have been suggested. A neuro-fuzzy approach is utilised for predicting and classifying the faults. Based on the observations, it is concluded, that the proposed model provides high accuracy in discrimination between faulty and fault-free classes. Besides the size of classes, the frequency of method invocations and the depth of inheritance hierarchies seem to be the main driving factors of fault proneness. An ANFIS based model for predicting faulty classes with a data set of 965 members have been experimented in this paper. Training has been done using LM model and gradient descent methods and set of 15 rules developed for this FIS. The observed results show good prediction of faulty classes.

ABSTRACT
In the single diffusion method, pure and Calcium, Cadmium, Magnesium doped zinc hydrogen phosphate (MZHP) crystals grow in the silica gel medium using different gel densities and various concentrations of orthoposphoric acid and supernatant solutions. Silica gel obtained from sodium metasilicate with a strongly acidic cation exchange in the H-form, was used for crystal growth experiments. The influence of pH, gel concentration and concentration of upper and lower reactants on the size, quality and nucleation density of the crystals is discussed. The techniques of concentration programming and seeded growth are used to enhance the crystal size. The pH range in which HPO42− ions dominates were considered which in turn is necessary for the growth of Zinc hydrogen phosphate (ZHP), Calcium doped zinc hydrogen phosphate (CAZHP), Cadmium doped zinc hydrogen phosphate (CDZHP) and Magnesium doped zinc hydrogen phosphate (MZHP) crystals. Crystals with different morphologies and habits were obtained. Some of them were transparent platelet, diamond shaped and some are twined. The effect of various growth parameters on the nucleation rate of these crystals was studied.

ABSTRACT
Cloud computing offers access to boundless virtual resources dynamically provisioned on demand for various applications like scientific workflows, big data processing application, Business Intelligence based applications, HPC and HTC. With heterogeneous cloud service platforms and cloud service providers, an efficient scheduling algorithms becomes more appropriate research topic recent days. In this study we present a comprehensive survey of various existing workflow scheduling algorithms and issues of scheduling in the cloud computing environment. The resource scheduling is a dynamic problem it is associated with: On-demand resource provisioning, fault tolerance support, hybrid resource scheduling with appropriate Quality of Service, considering time - cost and Budget. Since the implementations are more complex to be carried in a real environment, much of this research works are carried in the simulation environment. Keeping these parameters in mind, this paper also recommends the future direction towards workflow scheduling in cloud. Research in this arena is only in its infancy but with the rapid evolution of techniques more exciting approaches are likely to emerge.

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/196-200

ABSTRACT
As a maintenance programme that entails a modern approach for equipment and plant maintenance, Total Productive maintenance (TPM) underscores all features of production, as it aims to integrate maintenance and services of machines into a plant’s daily routine, thereby reducing unscheduled and emergency stoppages and repairs to the barest minimum. This paper gave a detailed definition of Total Productive maintenance, and explained that its aim is to remarkably improve products’ quality, and throughput, eliminate frequent machine stoppages and rework, leading to a dependable production system which will increase workers morale and job satisfaction. However, it was observed that TPM cannot be successfully implemented in a firm without the total approval and involvement of top management and employees, as they have to form teams that must oversee the activities of the manufacturing strategy. Apart from increase in quality of products and profitability, other benefits of a successful TPM implementation include better job satisfaction and staff morale, increased throughput and product’s quality, as well as reduced manufacturing cost, this is because the main target is to reduce the occurrence of emergency breakdowns and unscheduled maintenance to the barest minimum. The challenges of TPM which must be overcome for enhanced benefits include inadequate knowledge of TPM, lack of leadership and management support, organizational culture, excess inventory, and inadequate trainings. The paper concluded by stating that the six major losses of faulty equipment and operation could be addressed by the introduction of Overall Equipment Effectiveness (OEE) model, which sets targets of zero breakdown and reduction of setup and adjustment.

The plant layout design, its major objectives, and the equations for analytical calculations of work in progress and efficiency in plant layout design were also discussed, before the paper concluded on the need for manufacturers to have a well-designed functional plant layout that will be able to switch from one line of product to another without major alterations.

SHOP FLOOR VIBRATION ANALYSIS AND CONTROL

Authors: Okpala, Charles Chikwendu

IJAET/ Volume VII/ Issue III/ July-Sept.'2016/207-211

ABSTRACT
Despite the fact that vibration has some advantages and could be desired, like in conveyor belts and sifting operations, its negative effect ranges from minute to disaster, based on the seriousness of the disturbance and the nature of the machines. This paper gave a detailed definition of vibration, before classifying it as free, forced, damped and undamped, linear and non-linear, as well as deterministic and random vibrations. It explained that the objective of Vibration Analysis applied to an industrial or maintenance environment aims to reduce maintenance costs and equipment downtime by detecting and repairing faulty equipment. It further observed that the first step in controlling vibrations in the shop floor is to establish the source of the vibration, which may be emanating from rhythmic activities, movements of materials and equipment, walking, or other external sources that may likely introduce vibration via the ground. In conclusion isolation, passive control, stiffening, effects reduction, damping, and activities relocation were advocated as the effective measures of controlling vibrations in the shop floors.
