In 2008, our global plastic consumption worldwide has been estimated at 260 million tons, and, according to a 2012 report by Global Industry Analysts, plastic consumption is to reach 297.5 million tons by 2015. Plastic is versatile, lightweight, flexible, - 370 - moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. Moreover only limited studies have been carried out in India on the use of waste plastic (PET) for the development of high strength concrete with addition of polypropylene fibers. Polyethylene Terephthalate (PET) is usually used for carbonated beverage and water bottles. The construction industry is in require of finding cost effective materials for increasing the strength of concrete structures. In this paper deals with the possibility of using the waste PET bottles and polypropylene fiber size of fibre added in to the concrete with 1%, and 1.5% PET bottle fibers.

The increase in water consumption during recent years has emphasized the necessity for water utility personnel and engineers to produce water economically and in sufficient quantities. This is particularly true during peak demand periods, which may often coincide with unfavorable operating conditions caused by adverse quality. The treatment methods used to cope with these conditions are not normally successful and inevitably result in short filter runs. The short filter run is important primarily because it results in loss of revenue to the water utility. Short filter runs create expensive problems. Loss in - 368 - plant capacity and excessive wash water usage are attributable directly to this problem. In addition, poor raw water quality, which, in turn, usually requires higher chemical doses, generally occurs during period of short filter runs. If such periods are prolonged, the water treatment plant so afflicted is faced with a sizable financial loss, possible costly expansion and of more importance a reduction in service adequacy. Water suppliers use a variety of treatment processes to remove contaminants from raw water. The most commonly used processes include filtration, flocculation, sedimentation and disinfection for surface water. Water utilities select a combination of treatment processes that is the most appropriate to treat the contaminants found in the raw water. The appropriate technical skills, if applied, may impart great benefits, both spatially and temporarily, to augment the existing water treatment facilities. The raw water quality associated problems with reference to WTP's at Jodhpur city have been documented in this paper.

013268   Patel M;Mashru N (NO, , ) : Effect of flexibility on aircraft wing. J Aerospace Engng Technol 2016, 6(1), 45-50.

The shape of the aerofoil determines how the air circulates around it and how much moment and force will be the acting on it. When the body is rigid (fixed) flow around the geometry remains unchanged at particular A.O.A. (angle of attack), but if the body is allowed to be flexible (free) i.e., it can deform its shape, due to which there will be a significant change in the shape of geometry that consequently changes the motion of air flow around it altering the moment and forces generated. This will led to a change in the distribution of pressure on the flexible membrane causing the A.O.A. to vary, due to which wing's geometrical shape try to adopt it accordingly by forming a luff. This luff is mostly formed from the leading edge i.e., due to the membrane's elastic nature; in the flow to adjust change prevailed. A computational approach was made to understand this effect. This was the main purpose of the project to be carried out. The dissertation mainly focuses onto understand the effect of flexibility on aerodynamics and performance of wing compared to the normal rigid wing section using the most simplified case for long term goal of finding out the behavior of aerodynamics on wings of pterosaur with and without fairing (soft membrane). The study was carried out by taking into account a specific case of pterosaur's gliding flight at a speed of 33.3 m/s. This project included two test cases firstly, the rigid wing and secondly the flexible membrane wing, which were tested for both steady and unsteady viscous incompressible flows. For both the test cases it was considered that tension is mainly dominated by elastic strain (Π1). Both the test cases were carried out at fixed Reynolds's number of 1.087 x 10⁵ and Mach number 0.098. Use of equation similar to the bending of beam equation which is often referred as "Young Laplace Equation" was incorporated, that was modeled to a discrete formulation using second order accurate finite difference scheme. When the membrane of the wing was considered flexible there was a significant effect on forces generated, which in turn had an effect on performance in terms of coefficient of lift. Finally, comparisons between performances based on coefficient of lift of both test cases were carried out. The results obtained shows that the coefficient of lift for flexible case increased by 40% when compared to the rigid wing.

Present experimental study is focused on the flat plate gutter made of different porous materials is to stabilize the flames for afterburner applications. The porous materials used for the gutters as a flame holder are Silicon Carbide (SiC), Zirconium Oxide (ZrO₂) and Aluminium Oxide (Al₂O₃). The porous material flat plate gutters with different orientation angles of 0°, 30°, 45°, 60° and 90° to the main stream flow. The flat plate shaped gutters made of porous materials are expected to produce strong recirculation zone in the downstream, which enhances the mixing process and increases the flame stabilization. Non-reactive flow studies are carried out and the recirculation zone area for each porous materials at five different orientations of the gutter are obtained experimentally. The experiments are conducted in the combustor test rig and the flat plate gutters are fitted in the combustor test rig with the help of plug type fixture. Air is fed through a radial blower with constant flow velocity of 4.5 m/s. The parameter of interest in the non-reactive flow studies are the - 366 - recirculation zone length and wake width behind the gutter. The plots are drawn for the velocity fluctuations along the length of the combustor for different porous materials. It is observed that, due to irregular pores in the porous materials, the velocity fluctuations are higher immediately behind the gutter and gradually reduces in the downstream up to the exit plane. It is also observed that the recirculation zone length and wake width differs for different porous materials at different gutter orientation angles. The recirculation zone area is obtained by recirculation zone length and wake width and the maximum recirculation zone area is obtained at an angle 90° for all the three porous materials.

Energy is one of the principle driving forces in the present world, it is transforming our lives and shaping our future. However, the conventional energy sources are lessening due to increase in population and exploitation of energy day by day. To overcome this problem, we need to implement the techniques of optimal utilization of conventional sources for conservation of energy. The present research article includes how renewable energy can be harnessed when the vehicles passes over a speed breaker using piezoelectric material. The concept of piezoelectricity from speed breaker is to harness energy, which is lost inevitably on daily basis. Kinetic energy of moving vehicle induces mechanical deformation of embedded piezoelectric material therefore produce electricity. This green energy can be used to recharge batteries, lighting street or used to offset some of the power coming from the main grid. The energy, which was lost on consistent basis, can now be the source of energy and help for greener tomorrow.

Oriental J Chem 2017, 33(1), 450-7.

Paper deals with the influence of blend polymers on the physico-mechanical properties of Portland cement pastes including, W/C ratio, setting time, workability, density, porosity and compressive strength. Blend polymers were used based on methyl cellulose (MC) of different molecular weight (4x10⁴ and 8.3x10⁴ g/mol) and poly(acrylic acid) (PAA). The result showed that, the physico-mechanical properties of the cement pastes are dependent on molecular weight of MC. However, the addition of MC/PAA blend into cement, the W/C-ratio, setting time and density decrease while the compressive strength and flow increase.

The proposed modulation technique employs quadrature mixing to achieve transmission of high frequency data over a narrow channel. In this modulation technique, the phase of carrier is varied in accordance with the instantaneous amplitude of the message signal. The message data bits are transformed to an unintelligible form which then modulates a carrier signal. The modulation technique induces probabilistic characteristic over the entire process. The nondeterministic nature of data is enhanced and thereby providing integrity and confidentiality to the data which is transmitted across a channel. Another important feature of this technique is that prediction of the message data bits by observing the modulated signal is foiled due to the use of different phase shifts for 40 symbols. In this technique, the spectrum of modulated signal is translated to be centered at 0 Hz. At the demodulator, the instantaneous amplitude and phase can easily be determined. The major advantage of this digital modulation technique is that, signaling rate, requirement of high frequency carrier and transmission channel bandwidth is reduced to a considerable extent without compromising the transmission capacity and data rate.

013263   Nair P G;Dasari J;Poovalingam S (NO, , ) : Stress concentration factors for stiffener run-out regions. J Aerospace Engng Technol 2016, 6(1), 51-61.

Stiffener and stringer run-out is a common design feature followed in aircraft structures such as fuselage, wings and empennage. The run-outs are necessary due to specific structural and interface requirements. These run-outs act as a stress raisers similar to any geometric discontinuity in these structures. The stress concentration factors (SCFs) are available only for stiffener with 90° run-outs (also known as shoulder fillets) in the literature. In the absence of SCFs for other run-outs conservatively, the SCFs of shoulder fillets are used for all the configurations which results in over design of the structures. This paper aims at calculating the SCFs for various stiffener run-out configurations and arrive at the knock down factors (KDFs) using the finite element approach with respect to the 90 ° run-out configurations. Best stiffener run-out configuration is also proposed for improving the static strength and fatigue life of structures by reducing the local stress concentration.

Optimum production from a gas lift well mainly depends on proper injection gas quantity; injection pressure and depth of injection and gas lift valve performance. The quality of down hole gas lift valves plays a crucial role in achieving maximum efficiency of a gas lift system and uninterrupted oil and gas production. Gas lift valves can aid in the unloading and produce of a well. With the valves properly spaced and correctly pressured and proper selection of the port size, unloading proceeds in a stage-by-stage, valve-by-valve manner to the ideal point of lift, and maximum liquid production is reached. But if well situations change or if the gas lift design data was not very perfect, maximum liquid production is not achieved. Improper valve location, improper setting of operating pressures and gas pass at more than one point can stop wells from achieving maximum production. In this paper, smart gas lift valve which allows the port size of the gas lift to be remotely adjusted from the surface used computer program to determination of gas passage through the valve in order to distil real-time data on gas lift valve, on their turn these data are finally used for implementing conscious and forward looking control actions, ultimate results are, improved production profitability due to increased production rate, decreased operations cost and developed availability. Also the paper will address how smart gas lift valve will gain large benefits with different scenarios in natural flow and gas lift wells, will be illustrated in this paper; also investigate the effect of the valve port size, depth of injection on well productivity. The results show that smart gas lift valve can be used to control the amount of gas injection from down hole that leads to improve tubing well head pressure and enhanced well production and also indicated that the optimum opening is at 50% for both injection pressure rates.

Vegetal products are increasingly gaining ground in the composition of industrial and construction materials given their cost effectiveness and the growing concern about issues such as environmental protection and sustainability. Arabic Gum Biopolymer (AGB), a wild plant product found mainly in Sudan and also produced in other tropical African areas, has been widely used in various industries. Whereas its utilization is very limited in the construction sector, there is a clear indication that ABG has a potential for being an effective additive to concrete mixes that would improve fresh and hardened concrete properties. The aim of the present work is to evaluate the influence of AGB on the physical and mechanical properties of ordinary concrete at various ages including workability and air content of the fresh mix and porosity, capillarity and compressive strength after hardening. An experimental campaign is conducted to measure these properties from samples of sand concrete made out of mixes with different percentages of AGB dissolved in the mixture water. The experimental results show near 8% improvement in compressive strength for an optimum percentage of AGB of 0.9%. Porosity and capillarity vary consistently with compressive strength and exhibit a minimum where strength is highest. Air content monotonously decreases to a low minimum as AGB fraction is augmented. Workability is found to always increase with %AGB. Test results show a Slum range of 15-25 mm for AGB percentages ranging from 0.44 to the point of maximum strength.

Cold-chain management in India has been accelerated in last decades to reduce postharvest losses. However, most of the tropical and sub-tropical agricultural as well as horticultural produce goes in waste due to its perishable nature and improper cold chain management on-farm. Thus, apart from the large cold storage chambers for long-term storage, refrigeration system are also required for on-farm or in production catchment for agricultural crops during short-term storage. However, designing an on-farm cold storage is a challenge due to its complexities during design and refrigeration system. In this paper, a software, 'HimSaurya' was developed for Solar PV powered on-farm cold storage design. It was developed in Visual Studio Express Desktop 2012 environment. Cold storage structural design, refrigeration system equipment and solar PV panel design were implemented in Himsaurya. The vapor absorption system (VAS) was adopted in cold storage refrigeration system. An optimized energy efficiency was also investigated further using the HOMER software. The sensitivity of HimSaurya was assessed for different tropical, and subtropical agricultural produce e.g. mango, sapota, strawberry, and tomato. Results are showing a linear trend in cooling load with respect to product storage capacity. The results are promising with improving storage quality and reducing wastage of perishable agricultural produce.

Aircraft anti-icing system is one of the key components without which aircraft icing related problems cannot be solved. Considering the long history of aircraft building technologies the involvement of anti-icing system has a remarkable influence over it. Basically there exist two types of aircraft anti-icing systems namely, the first one is electro-thermal anti-icing system the second one is bleed air anti-icing system. For propellers electro-thermal anti-icing system is used and for fixed wing planes the bleed air anti-icing system is used to prevent icing on the wings. Apart from these two anti-icing systems there exist several other anti-icing systems for the prevention of ice formation. It should be noted that anti-icing and de-icing are two different systems with different purposes. A short study of different aircraft anti-icing systems has been carried out for better understanding. The paper shows various aspects and methods of anti-icing systems used.

The primary objective of current work is to narrow in on an airfoil which is capable of producing high lift to drag ratio with a high aspect ratio at low Reynolds number which in turn helps in reducing the operational cost involved for UAV's. In order to authenticate the sanctity of the results obtained from - 360 - computational analysis using XFOIL software package, the experimental results for pressure distribution and L/D ratio obtained for NACA series airfoils (0012 and 6412) from wind tunnel calibrated for the required set of values are compared with the results obtained from XFOIL software package, the comparison made satisfy the convergence criteria. Further, from the critical evaluation of the computational data obtained for various series of airfoils, it is evident that S 7075 (Selig series) airfoils produces maximum L/D ratio at low Reynolds number. Based upon this critical evaluation, S 7075 series airfoil is narrowed down for 3D Printing and the experiment is carried out for validating results with the computational analysis.

Indian J Engng Mater Sci 2016, 23(4), 207-22.

Metal matrix composites have been regarded to be one of the most principal classifications in composite materials. Microstructural analysis and metallography is one of the predominant terms commonly used in the research of materials. The thermal characterization of composite materials has received broad deliberation and has become governing in materials science and engineering. In this paper, the microstructural investigation of Al 6061, silicon carbide (SiC) and graphite (Gr) hybrid metal matrix composites with varying percentage reinforcements 2.5%, 5%, 7.5% and 10% have been carried out. The analysis of these hybrid compositions have been accomplished by using optical microscope, scanning electron microscope and energy dispersive spectroscopy that benefits to accomplish thermal characterization and analysis of composite material. Aluminium based composites reinforced with silicon carbide and graphite particles have been prepared by stir casting technique. It has been observed that, dispersoid concentration of the reinforcements has been homogeneous and negligible porosity has been noticed. The formations of grain boundary, interdendritic segregation, porosity and particle size have been characterized by using scanning electron microscope (SEM) and optical microscope. Elemental characterization has been achieved by using energy dispersive spectroscope (EDS).The investigation of thermal conductivity behaviour of hybrid composites with varying percentage reinforcements at lower proportions have been emphasized.

Weight of aircraft structures plays a vital role in enhancing the business revenues of the manufacturers and end customers. Thus, the aircraft designers and manufacturers attempt to produce structures that are optimized for weight, cost, and at the same time serves the structural integrity, performance and safety requirements as specified by the certification agencies. One way to approach the problem of excess weight is to figure out the innovative analysis method, which predicts realistic failure modes and factors of safeties. In addition to this, care must be taken such that investment on analysis is under acceptable limits. As of today, most of the aerospace industry conservatively uses cantilever or fixed-fixed methods to check the adequacy of strength for rib flange bending for aircraft wings. This paper discusses various analysis methods to check rib flange bending and present a comparative study of the results and quantifies the amount of conservatism in each analysis approach through finite element method validation (FEMV). The methods discussed in this paper are usually not available in the optimization tools like FEA based software OptiStruct and NASTRAN. Eventually, this paper help the readers to identify the most preferred method for rib flange bending check, which is profitable from the point of view of optimization of weight, cost and robust structural integrity and least analysis time requirement.

The rooftop solar market is at an early stage in India with many potential participants. India will likely see a record growth in the rooftop solar segment in the coming years. The current project aims at mapping the Solar Rooftop and designing the layout for the Photovoltaic (PV) modules on the roofs of a subset of New Delhi region. The project includes estimation of the height of the buildings using a high resolution optical imagery, from shadow of the building, without involving any physical measurement. These heights are then utilized to prepare 3D Models for Solar Rooftop Mapping using Geographical Information System (GIS) and Remote Sensing. Occlusions and shadows, which lead to poor distinction of neighboring buildings, can have a significant impact on 3D modeling. Important data included the angle and alignment of the roof, the sun's path across the sky, shadows cast by a chimney or another rooftop over the course of the day, and the seasonal change in hours of sunlight. 3D building model was designed using various softwares. After solar irradiance calculations and finding out the shadow free area on the roofs, i.e. Photovoltaic (PV) layout of the rooftops can be used for effective and efficient installation of PV modules. This project is an attempt to utilize renewable energy resources by placing photovoltaic modules on rooftops for fulfilling residential electricity purposes.

In this study, the effects of lamination conditions on some commercial high density fiberboard (HDF) panels surface quality characteristics, surface strength, impact resistance test (large diameter ball test), curing degree, scratch resistance, abrasion resistance are investigated. For this purpose, HDF panels are produced from mixture wood fibers (50% black pine and 50% beech wood) as 8.3 mm thickness. After panels sanded to 7.3 mm thickness, laminated at different pressures and times. It has been found that high pressure and short-term press - 357 - time conditions have significant effect on surface strength, impact resistance, and abrasion resistance values. The best surface quality measurements are obtained from A1 group, pressure 340 kg/m² and 13 s pressing time (average of surface strength value of this group is 1.83 N/mm², impact resistance value is 25.25 N and abrasion resistance value is 3650 revolution), but the lowest value is B3 groups, 320 kg/m² pressure and pressing time of 18 s (average of surface strength of this group is 1.58 N/mm², impact resistance value is 20 N and abrasion resistance value is 3200 revolutions). Besides production factors of HDF panels and laminating material properties, press operating conditions have been found to be decisive factors in laminate parquet pressing process for high surface quality.

The modified fuel supply system to the existing L-39 aircraft was designed to overcome some of the envisaged problems associated with the loss of lives and properties of humans. This design work brings a devising means to cater for this problem by introducing an alternative booster pump which will serve same purpose as that of the main pumped. These proposed modifications to the fuel supply systems include a pipe interconnecting the emergency booster pump, shut off valve at the defective booster pump and one emergency valve. The new piping to interconnect the fuel pump from emergency booster pump are said to be of the same diameter and material, with the existing pipe diameter. Just like the main booster pump, the voltage of the main pump is sourced from the aircraft battery. This modification will be activated in the event of main booster pump failure. Furthermore, this modification is cheap, easy to maintain and does not impose any significant weight changes on the aircraft.

Microseismic has been used basically to monitor hydraulic fracturing, which is a short term plan and to monitor steam injection, a long term plan. Recent advances in microseismicity technology has led to an increase in its usage in the reservoir monitoring activities such as gas storage, co2 injection, hydraulic fracture operations, production monitoring (oil and gas) etc., and thus, fast becoming a viable technique in oil and gas industry. This is because of its unique service it renders through provision of fast and accurate information about stress changes in a reservoir and the associated geomechanical deformation which are used to characterize complex fracture networks and fluid flow paths. Due to its relevance in monitoring fracture network and fluid flow paths, a lot of efforts and innovations in the recent years have been channeled to improving its mode of operations and its imaging capabilities. In this study, we highlighted the methods of acquiring and processing microseismic data, their limitations and pitfalls and its applications in - 356 - unconventional reservoirs.

The building envelope is subjected to climatic influences by its individual orientation and composition. The main function of the building envelope in hot climates is to minimize external heat stress. Indoor thermal control can only be achieved through understanding of the thermal performance of the building envelope in relation to relevant weather parameters. It is also becoming increasingly realized that much can be done to mitigate heat stress in unconditioned buildings and to reduce cooling and heating loads and the energy consumption of air conditioned buildings, through a proper choice of building envelope materials and envelope design. The envelope's response to climatic conditions is a major determinant of the amount of energy required to maintain the building's thermal environment. Also, he building envelope directly influences the cooling peaks and air conditioning system capacity requirements. The thermal properties of the envelope are determined by the combination of wall mass, thermal resistance; insulation location, external surface colour, texture, and size. Heating, ventilation and air conditioning (HVAC) systems in buildings aim to control the indoor climate in order to keep occupants comfortable by control the temperature and air flow. To achieve this purpose, it is necessary to have adaptable control systems that could deal with the parameters required to control the indoor climatic conditions. There are for this purpose computer models that could simulate indoor climatic processes and how to control their parameters. The success of the modeling process depends on the ability to deal with changing conditions and respond effectively as much as possible so as to maintain the necessary conditions for comfort of the occupants taking into account the cost. In this paper a thermal model for a residential room has been developed using Simulink/MATLAB trying to deal mainly with the issue of maintaining the desired indoor temperature in spite of the change in outdoor conditions.

Int J civ struct Engng 2016, 6(3), 245-62.

One of the main problems of conventional concrete under water is the high percentage of material loss due to the washout of cement paste. This research presents the influence of anti washout admixture (AWA) and coarse aggregate types on various properties of self-flowing underwater concrete. AWA is water soluble organic polymer, which increases the cohesion of concrete, in a way that significantly reduces the washout of the finer particles, i.e., the cementitious material and sand from fresh concrete when it is placed underwater. The work involves three groups with the total number of twenty-four self-flowing underwater underwater-concrete mixes. The test program was designed and arranged to consider the effect of four different parameters as follows; AWA (0.0, 0.2, 0.3, 0.4 and 0.5%) by weight of cement, cement contents (450,500 and 550 kg/m³), type aggregates (steel slag, crashed dolomite, gravel) and fine materials (content and type). All concrete mix contains high-range water reducing 4% by weight of cement. The ?ne to coarse aggregate was 1:1. The concrete mixtures were tested for slump flow, blocking Ratio, GTM screen stability, air content, weight loss method that is the plunge test CRDC61 which is widely used in North America, and compressive strength. Compressive strengths were evaluated at 7 and 28 days age for under-water casting as well as air casting conditions. Test results indicated that the use of an AWA facilitates the production of self-flowing underwater concrete with the added benefit of lower washout loss.

An attempted has been made to evaluate the strength and performance characteristics of cold mix bitumen using reclaimed asphalt. An experimental result obtained from laboratory testing of the physical and mechanical parameters of the recycled material, in which the material from the existing pavement layers were analyses. The air void content, Marshall stability and flow of the recycled mixtures were investigated. The tests were performed on the road base mixtures incorporating reclaimed asphalt pavement (RAP) with bituminous emulsion. It was observed that the reclaimed asphalt was having impact strength of 10%, crushing strength of 8.2%. It is significant to note that the reclaimed aggregate which was subjected to loading condition already was still showing very good strength properties. The maximum stability obtained from optimum binder content was 384 kg which is a very good value for a cold mix made up of reclaimed asphalt aggregate. The flow value obtained was also 5.06 mm as observed. The aim of the tests was to evaluate the properties of the mixes in terms of the recycled aggregates. Satisfactory results were obtained.

Indian J Engng Mater Sci 2016, 23(4), 231-8.

In the present work, mechanical, thermal and water absorption properties of hybrid sisal/jute fiber reinforced polymer composite have been investigated. Hybrid composites are prepared by hand lay-up technique keeping constant 30 wt% of total fibers content with various weight ratios of jute and sisal fibers. Mechanical properties such as tensile, flexural and impact are investigated as per ASTM standards. Tensile and flexural test are carried out using Tinius Olsen H 10 K-L Universal Testing Machine with cross head speed of 2 mm/min. In addition, impact test is carried out using Tinius Olsen Impact 104 machine as per ASTM D 256. Thermal stability of prepared composites is obtained using Perkin Elmer TGA 4000 apparatus within temperature 30°C - 800°C in nitrogen atmosphere. Water absorption test is carried out as per ASTM D570 to obtain the maximum water uptake, sorption, diffusion and permeability coefficient. Moreover, morphological analysis is carried out to observe the fracture behavior and fiber pull out of the composite samples using scanning electron microscope. The results indicate that hybrid composite having 50% jute and 50% sisal (J50S50) has higher mechanical and thermal property and lower water absorption property than jute, sisal and other hybrid composites. For further improvement in the property of hybrid composite J50S50, alkali treatment of fibers is carried out and its positive effect is observed in terms of increase in mechanical and thermal properties and decrease in water absorption properties. The present prepared composite can be used in packaging, light weight automotive parts and construction applications.

Every aircraft essentially consists of an environmental control system (ECS) which is very much required to control the interior environment for the flight crew and the equipment. The charged air (compressed air) from the seventh stage of compressor unit of engine is tapped used for cooling the cockpit and avionic system. The charged air is made to pass through the various components of the ECS such as pre-cooler, primary heat exchanger, secondary heat exchanger, cold air unit, condenser etc., thus, the charged air is converted to required temperature and pressure and is utilized for the cooling purpose. In the current research paper, the design of control unit bracket locator for ECS is done with CATIA V5 R20. The structural analysis is very essential to ensure the concept that it can meet the requirements. We have furnished by using an analysis software package called ANSYS. The analysis by using ANSYS 14.5 package gave us the desired results in the work undertaken by us. The new design is done by using essential software, to reduce the prototype costing and bring out a conceptual design. For implementing any new design in an aircraft, the various analysis such as stress analysis, flow analysis and thermal analysis of the design are very essential. Since the design is a new concept and it has to withstand various loads and so there is a need to analyze it for different critical parameters.

The release of phenol from wastewater by various industries like petroleum, petrochemical, pulp and paper causes harmful effects on the environment. Adsorption using activated carbon from agricultural waste precursor material has proven to be effective for the removal of phenolic compounds from wastewater. Therefore, it is important to understand the sorption kinetic mechanism in wastewater treatment, since it brings down the problem of large sludge-handling processes. The kinetic analysis also helps in designing large scale treatment plants which have high efficiency and results in high quality treatment of the effluent. In addition, it also assists in proposing the mathematical models, reaction pathways that describe the characteristics of an actual treatment plant. Various theoretical kinetic models are available for determining the mechanism of the adsorption process. In this review, mainly six kinetic models were investigated to study the adsorbate-adsorbent interactions and to find the rate limiting step. From the recent literature, higher correlation coefficient values were obtained for the pseudo-second-order kinetic model showing that it is the most appropriate one for most of the systems. The pseudo-second order kinetic equation shows that the chemisorption was found to be rate determining step in most of the adsorption process.

Int J appl Sci Engng Res 2016, 5(1), 62-71.

In this research work, the reliability of a locally designed and constructed clap activated switch was determined. The sound of clap is detected by a small condenser microphone. The microphone transduces the sound wave to electrical waves which is further amplified by transistor connected in the common emitter configuration. The amplified output from the transistor is then fed to the Bistable Multivibrator circuit. The part count method which assumes typical operating conditions of part or components complexity, ambient temperature, various electrical stresses, operation mode and environment (called reference conditions) was used for the estimation of the reliability of the Clap Activation Switch. It is observed that the reliability of the Clap Activated Switch constructed locally have an estimated reliability that ranges between 0.99706 for the first year of operation to 0.94299 around the twentieth year of operation. Further work can be done by evaluating the reliability of the device using part stress analysis; this will enable the determination of the reliability under actual operating conditions to be carried out.
