022742   Anas M;Kumar S R;Shukla V (NO, , ) : Efficient solar panel design and fabrication for solar vehicle. J Instrum Technol Innovation 2017, 7(1), 20-4.

Since few decades, research in solar power generation techniques is taking pace as there is a need for environment friendly energy. The demand of green energy has made recent scientist and engineers to join hands together for finding solution to meet the scarce of fuel - 202 - energy. The public demand for solar panel is rising high because of increased electricity rates of units. This paper presents the efficient fabricated and optimized assembly of the solar cells to generate energy for driving a single seater vehicle. The details of the panel, cell array in series or in parallel and extended or fastenable welded structures are also presented which easily bears the shocks, sudden pull and push of the vehicle. The solar panel is sandwiched between a plastic sheet and wooden board, and needs special care as the entire structure experiences a type of pull and push, when the vehicle accelerates or stops. The economical and easier operation demands high technology for efficient generation of solar energy. The panel is efficient to drive a vehicle to a speed of 35 km/h, which is very close to ideal speed, by using solar energy and hence protecting our environment from pollution.

Curr Sci 2017, 113(2), 272-83.

Microalgae have received a great deal of attention among researchers in recent decades in the production of sustainable bioenergy due to the limitations of second-generation biofuels. However, scalability and economics are the two key challenges that need to be overcome for sustainable biofuel production at field level, and mathematical modelling can be utilized as an effective tool to evaluate the influencing factors. This article focuses on the mathematical modelling of microalgal growth and carbon dioxide sequestration potential of a fixed photobioreactor (PBR) at 25° inclination facing south and a two-axis trackable PBR in Odisha, India. The total geographic area of Odisha has been represented in 1195 spatial sites, each site representing around 130 sq. km of the real scale dimensions approximately. The model incorporates site-specific data of solar radiation, climatic conditions and PBR configurations to derive the bioenergy content of microalgal biomass by photon energy balance. The effect of photoinhibition was also studied, and the outputs from the mathematical modelling, such as daily microalgal lipid production and carbon dioxide sequestration potential were plotted for the whole of Odisha using QGIS software. The net microalgal biomass production rate drastically reduced to around 30% and 40% due to the effect of photoinhibition in the case of fixed and trackable PBR systems respectively. The outcome of the present study could influence the policy-makers for selecting suitable sites for the implementation of microalgal-based biofuel production facility.

Upwinding allows for accurate, non-oscillatory capturing of shocks waves; however, many Riemann solvers (both exact and approximate) suffer from some soft of numerical instability. One of the most mysterious and least understood of these is the carbuncle phenomenon. In the present study we analyse the closely allied "simplified carbuncle" problem, also known as the 2D shock stability problem or the 1.5D carbuncle problem. Motivated by the existence of some recently derived schemes that do not exhibit the instability, we perform a thorough stability analysis and extended previous studies by analysing the pseudo-spectra and hence the effects of non-normality in causing this instability. Our results establish that, contrary to previous indications in the literature, a non-linear mechanism is responsible for the instability. In order to understand the nature of this non-linear mechanism better, we perform a non-linear analysis of the sonic glitch, which shares some common features with the carbuncle. We provide two previously unknown results. Firstly, we show that even the "entropy-satisfying" Godunov scheme violates the entropy condition in the sonic glitch. Secondly, we provide a more accurate definition for the entropy condition for scalar conservation laws that supports the previous claim. We conjecture that a similar non-linear anti-dissipative mechanism might be responsible in triggering the carbuncle. This work is expected to lead to a better understanding of possible unphysical behaviour in - 201 - Riemann solvers and thus help in the design of better solvers for high-Reynolds-number flows.

Sadhana 2017, 42(5), 641-53.

The optimization of peak detection algorithms for electroencephalogram (EEG) signal analysis is an ongoing project; previously existing algorithms have been used with different models to detect EEG peaks in various applications. However, none of the existing techniques perform adequately in eye event-related applications. Therefore, we aimed to develop a general procedure for eye event-related applications based on feature weight learning (FWL), through the use of a neural network with random weights (NNRW) as the classifier. The FWL is performed using a particle swarm optimization algorithm, applied to the well-studied Dumpala, Acir, Liu and Dingle peak detection models, where the associated features are considered as inputs to the NNRW with and without FWL. The combination of all the associated features from the four models is also considered, as a comprehensive model for validation purposes. Real EEG data recorded from two channels of 20 healthy volunteers were used to perform the model simulations. The data set consisted of 40 peaks arising in the frontal eye field in association with a change of horizontal eye gaze direction. It was found that the NNRW in conjunction with FWL has better performance than NNRW alone for all four peak detection models, of which the Dingle model gave the highest performance, with 74% accuracy.

Emotion has a significant part in cooperation and correspondence between individuals. Emotion can be communicated either verbally through emotional vocabulary, or by communicating non-verbal prompts, for example, sound of voice, outward appearances and motions. As of late, estimation of human emotions from Electroencephalogram (EEG) signals assumes a crucial part in evolving academic Brain Computer Interface (BCI) devices. In this article we present a novel approach to classify human emotions using a two-tier classifier which is a combination of both K-Nearest Neighbour (K-NN) and Neural Network (NN) classifier. The useful informations for classification is extracted from the input EEG signals after noise removal which is done by the process of pre-processing. The proposed work is implemented on MATLAB and the simulation results are presented.

Fiber wireless access network is a promising access network due to provision of higher bandwidth, flexibility and ubiquity. One of the main challenges for a FiWi access network is to minimize energy consumption. In this network, there are many concerns like ONU placement, ONU sleep mechanisms, power saving mechanisms etc., which are accountable for achieving energy efficiency. Routing is another aspect at the front end of the network, which may contribute to bring energy efficiency. There are multiple paths from source to destination at front end; therefore selection of appropriate and energy efficient path is indispensable. This paper proposes an integrated routing algorithm, which finds the routes on the basis of distance and angle, for a single source destination pair. The route which consumes lesser energy is selected for communication. Results show that energy consumption is reduced using proposed algorithm as compared to existing approaches, while maintaining limited delay.

The proposed area of research is to reduce the power consumption, leakage voltage, leakage current and leakage power of DRAM while maintaining the competitive performance. The Fin FET approach is used in DRAM for high performance. Fin type field effect transistors (Fin FET) are capable substitutes for bulk CMOS at the nano-scale. Fin FET are double gate device. A Fin FET uses an intrinsic body. It greatly suppresses the device-performance variability caused by the fluctuation in the number of dopant ions, while a planar-bulk MOSFET requires a heavily doped channel which causes serious process variability. A Fin FET based DRAM memory design has been proposed as an alternative solution to the bulk devices. Fin FET is suitable for future nano-scale memory circuit design due to its reduced short channel effects (SCE) and leakage current. Fin FET DRAM cells can reduce area and leakage power. Z` `By using the Fin FET CMOS technology we investigate that it provide low leakage and high performance operation by utilizing high speed, low Vt transistor for logic cell and low leakage.

Many technologies have been introduced to improve the production of agricultural produce. But very little is done to protect the produce from being eaten by rodents or other intruders. These challenges should also be taken into account. Security systems these days are not smart enough to provide real time notification after sensing the problem. The technologies like Internet of Things and Wireless Sensor Networks can lead to agricultural modernization. We have designed, tested and analyzed an 'Internet of Things' based device. Since, the devices in IoT have limited energy sources they often run on battery, the implementation of green communication and system design in IoT has been a core challenging issue.

Geopolymers have several applications and concrete is one of the materials that can be produced with geopolymer as binder. Since industrial byproducts/wastes such as fly ash, iron slag, micronized biomass silica, silica fume, red mud, etc. can be used as a binder instead of Portland cement, geopolymer concrete (GPC) has generated lot of interest among the scientific and engineering community. This has also resulted in reduced carbon footprint of concrete and an effective method of disposing industrial waste. In this study GPC with a blend of class-f fly ash and ground granulated blast furnace slag as binder has been developed, and its flexural and fracture characteristics have been studied. The GPC developed has a 28-day compressive strength in the range 40-50 MPa. Incorporation of steel fibres resulted in increased flexural strength, enhanced fracture properties and ductility.

Concrete has high compressive strength, but is remarkably weak in tension (about one-tenth its compressive strength), and as such, is usually reinforced with materials that are strong in tension. In the presence of reinforcement, the tensile load is transferred to the reinforcing material. An alternative to increasing the load carrying capacity of concrete in tension is the addition of fibres. Well-dispersed fibres in the concrete act to bridge the cracks that develop in concrete. The incorporation of fibres in a cement matrix leads to an increase in the toughness and tensile strength, and an improvement in the cracking and deformation characteristics of the resultant concrete. Sisal fibre is derived from the leaves of the plant. It is usually obtained by machine decortications in which the leaf is crushed between rollers and then mechanically scraped. The present study was carried out to check the fresh and hardened properties of sisal fiber reinforced self - 341 - -compacting concrete with different percentage of fiber addition. Degree of workability of concrete mix with 0.2% super plasticizer and water cement ratio 0.31 had good workability which is effective, was obtained.

Normally, the conventional controllers are used to get desired response when noise and disturbances are there but they cannot give desired response when the system parameters change. Due to the disturbances or any external effects, the system parameters may change. Dynamical system may face this type of problem because its dynamics may change with time. So, adaptive control can be used for this type of problem. Adaptive controller has some adjustment mechanism which will change the control law parameter according to the change in the system parameter, by which the controller parameter will change and required process response can be achieved. Here, adaptive control will be used with the model reference adaptive control (MRAC) with the MIT rule (Rule developed by a Massachusetts Institute of Technology). In MIT rule, the response totally depends on the value of a parameter which belongs to an adjustment mechanism of MRAC. The value of is very effective on the response of the process or system. The bound for the value of parameter can be achieved by trial and error method. If the value of parameter can be minimized with some optimization technique, then better response can be achieved. Here all the simulations are done in MATLAB Simulink.

Pond ash is the byproduct and is produce from coal plants. These plants release byproduct in major quantity which effects the environment. In this paper, an experimental work has been done on the conventional concrete with pond ash as replacement of fine aggregate. The grade of the concrete is M-40 and nine concrete mixes named as F1, F2, F3, G1, G2, G3, G4, G5 and G6 were prepared with different replacement ratios (10, 15 and 20 percent) of pond ash using alccofine 2.5 and 5 percent as replacement of cement. Each set of concrete mix comprised of 6 cubes, tested at the age of 7 and 28 days of curing period. it is concluded that optimum replacement of fine aggregate in M-40 is achieved at 15% pond ash using 5% alccofine. Therefore, the utilization of pond ash as partial replacement of fine aggregates will be feasible, economical and safe from environmental point of view and hence can be used as an alternative to fine aggregates.

On pressing a button, the data transfer will take place. It will be get sensed by the IR. As the receiver mounts at the toll plaza, the amount will get deducted automatically according to the toll charged and the remaining amount will be displayed. DC motor is used to open and close the gate. The concept proposed is of automatic toll tax payment system and the amount transaction information sent to the cell phone of the motorists through the GSM modem technology. The gate will get opened for the user, and for others, it will remain close. In this paper, we also include manual tax collection system. In that, we use two barrier gates. When the car passes the sensor sense the gate is opened. The toll amount is collected manually; then the authorized person presses the button and gate is opened. In this way, manual as well as automatic toll collection is included in this paper. The major advantage is that users are able to drive through the toll plaza at highway speeds without having to slow down to pay the toll.

The requirements of current day engineering applications is based on high damping materials which exhibit superior mechanical properties as well as high damping limit for vibrations. In structures made of metals and composites, it is difficult to achieve high damping limit and great mechanical properties at the same time. This is majorly due to the infinitesimal systems that result in "microscopic mechanisms and parameters affecting the mechanical strength". However, to accomplish a metal matrix composite system with unique properties of better mechanical properties as well as vibration characteristics; essential techniques involving the fabrication of hybrid composites with Aluminum 5083 as the base metal and Silicon carbide and fly ash as the reinforcement is considered. The composition of each of the reinforcements dispersed plays a particular part in affecting the damping characteristics or mechanical strength. In the current paper, the results of vibration tests carried out on hybrid Aluminium metal matrix composite plates as well as the results obtained from computational analysis using ANSYS software are interpreted to effectively determine the damping ratio, frequency, magnitude, phase angle and presented to understand the dynamic behavior of composite materials under the effect of different parameters.

J Aerospace Engng Technol 2017, 7(3), 38-45.

The present work is a comprehensive research carried out to fabricate and characterize the hybrid metal matrix composite materials by reinforcing the metal matrix of Aluminum 5083 (Al 5083), with ceramics and industrial wastes. More often than not, when no less than two reinforcements are available, it is known as a hybrid metal matrix composite and our work relevantly focuses on portrayal of these "hybrid metal matrix - 336 - composites" for aerospace applications, especially for aircraft components. Aluminum metal matrix composites with ceramic particles especially "Silicon carbide particulate reinforcements" are finding expanded applications in aircraft industry. In the present work, Aluminum 5083 is utilized as the matrix material into which SiCp and fly ash particulates are included as the reinforcements. The consequences of an exploratory examination of the mechanical properties of reinforced aluminium matrix (Al 5083) composites, synthesized by stir casting are accounted in this paper. Each set decided for present work had five kinds of composite specimens with 3, 5, 7, 9 and 11 Wt. % of silicon carbide and 4 Wt. % of fly ash that is kept consistent all through, since the reinforcements in the matrix phase should not surpass 15 Wt.%. A graphite crucible and a cast iron die are utilized to prepare the composite specimens. The mechanical properties examined are the tensile strength, compressive strength, ductility and hardness. It is discovered that the tensile strength, compressive strength and hardness of the aluminum combination (Al 5083) composites increased with the increase in weight percentage of silicon carbide up, while the ductility steadily diminished with the increment in weight percentage of silicon carbide reinforcements. Morphology of the composites and dissemination of the reinforcements are explored by optical microscopy and scanning electron micrographs. The aluminium metal matrix hybrid composite, thus fabricated is characterized for its use in aircraft components, since aircraft components requires better tensile strength, compressive strength and wear resistance.

Construction projects are initiated in dynamic environment which creates circumstances of high uncertainty and risks due to accumulation of many interrelated parameters. So, the need for establishing a systematic risk assessment for construction projects has increased more than ever before with the additional fact that the construction projects are becoming increasingly complex and dynamic. The aim of this paper is to provide a risk assessment methodology that provides a decision support tool, directed for the commercial construction projects. By the study of the risk registers of commercial construction projects, key risk factors category and their attributes which affects the project are identified based on the project objectives. The objective of this study is to perform risk assessment considering the project objectives and propose a risk index for the attributes which are identified, and rank them to prioritize the risk factors. The commonly identified factors from risk registers of various projects are subjected to survey and collected from project managers of an organization through mail or through personnel meeting. The survey questionnaire is designed to derive the relative importance of factors one over other by pair-wise comparison. By assigning a scale of values to rate the importance and by converting those to triangular fuzzy numbers, the fuzzified values are obtained. Those fuzzy numbers are aggregated, defuzzified and applied into analytic hierarchy process to obtain the priority vectors, by which ranking for the attributes is done.

Globally, India is the leading producer of fruits. Fruits after consumption leave a peel which is a nuisance to the environment as a solid waste. In this article, commonly available large volume-fruit peels (FP) (viz. banana, orange, citrus, lemon and jackfruit) were investigated for surface, physical and chemical characteristics with a view to propose their valorization in detail. Each FP was characterized by proximate and ultimate analysis, porosity, particle density, bulk density, point of zero charge (pH_pzc), surface pH, surface charges, water absorption capacity, BET surface area, scanning electron microscopy, Fourier transform infrared spectroscopy and TGA/derivative of thermogravimetric. The BET surface area of FP is very less, between 0.60 and 1.2 m² /g. The pH_pzc and - 332 - surface pH values of orange peel (OP), citrus peel (CP), lemon peel (LP) and jackfruit peels (JFP) are in the range of 3-4. The pH_pzc value and surface pH of banana peel (BP) is closer to 7. The order of surface acidity is OP <62> LP <62> CP <62> JFP <62> BP. From TG curves it is clear that FPs are stable below 150°C. The results will be useful for rational design, when FP is used as a substrate for bioactive compounds, phenolic antioxidants, organic acids, enzymes, biofertilizer, production of energy and as adsorbents.

As the requirement of infrastructure is increasing day by day, process - 331 - of new construction is increasing rapidly but the quantity of old infrastructures is more, also new construction has some limitations, so the pre-constructed structures should be maintained properly to achieve their full life and also to reach economic balance. Building structures deteriorate with respect to time due to various environmental conditions like temperature, presence of moisture, humidity and gases, large seismic events affect overall durability and health of the building. Corrosion of reinforcement in the concrete is the main reason in concrete deterioration. This effect may further increase and severity of damage may increase. The need of the present study is to have a time saving and accurate methods to analyse the structural health of the infrastructure and also to suggest preventive measures to increase the service life of the structure. SHM also brings a quantitative metric that, when used properly, can compare current and healthy states to determine the extent of degradation and damage and, moreover, can be applied to predict the lifespan of structural systems.

The gears are used to transmit the motion and power from one shaft to another shaft by physical contact between gear teeth. The bevel gear is used to transmit motion and power between the axis of intersection and the non-intersecting axis. Gears are generally subjected to loads due to these loads, tooth bending stress and contact stress will be developed on the gear tooth. Much research on the action of the gear has confirmed that contact stresses also influence the formation of pits on the surface of the tooth. Gear tooth is the most important element in a gear system and has been focused on the current study. An analysis has been carried out for the three different types of materials used to make the bevel gear. The failure of gears due to contact stress is high compared to bending stress. Stress analysis has been a key area of research to minimize failure of the gear and optimize the design. The study of contact stress developed between the mating gears are very important for the gear design. The current goal is that the finite element analysis of the bevel gear is performed to determine the maximum contact stress by ABAQUS as the solver and also the theoretical maximum contact stress is calculated by the Hertz equation. In this study finite element analysis results were validated with theoretical results.
