Moreover remedial actions for better utilization of availability of energy are proposed.

Abstract: Thanks to the technological advancement, the research in the autonomous aerial vehicle is growing and the prototypes configurations are developing. The quadrotor is one of Unmanned Aerial Vehicle (UAV). Increasing the capability of carrying a load and the endurance time of quadrotor are representing a challenge. In this paper, a new quadrotor model is designed and evaluated. This model is named VAL-quadrotor which based on varying the arms length to control the movements of attitude and position. VAL-quadrotor is designed to carry more load, by exploiting all motors power for carrying a load, while the attitude maneuverability Performed by using the arms length variation. In normal case without carrying the load this technique can exploit to increase the endurance time. The effect of the arms’ lengths is studied to select the appropriate length. Therefore, the simulation results proved that VAL-quadrotor possess the capability of carrying more load than the standard design.

Abstract: AISI1040 parts that carry critical loads in everything from automotive drive trains and jet engines to industrial bearings are produced by a series of processes, including time consuming and costly grinding and polishing operations. The main objective of machining is to produce a product of required shape and dimension with specific quality and surface finish. But cutting parameters are affecting the quality of process such as surface finish and material removal rate. The modern industry requires better way of machining that will not affect the quality of the product. Response surface design (RSD) is effective tool for modeling and it is solved by second order polynomial equation. So in this investigation, RSD is used for modeling and prediction of machining parameters on AISI1040 using TiCN/TiN and TiAlN coated tool under dry condition.

Abstract: Search and rescue robot is developed mainly to move through rubbles and debris. When a natural disaster such as an earthquake struck causing the building to collapsed, this robot can be used to search for victims and transfer to safe place. Search and rescue robot is equipped with a robotic arm to perform the evacuation process. With this robotic arm, robot can easily grab the victim in collapsed building and bring to safe place. Generally, there is a lot of robot like this used for rescue operation in collapsed building. But non of them is control by using mobile devices. So this paper is purposely designed to develop a prototype of robotic vehicle using mobile devices as controller by using Bluetooth transmission. The distance can vary from 10 meter to 100 meter depending on the type of Bluetooth module used. This robot is powered by Arduino Uno R3 board using 9V AA battery for power supply. In order to control this robot using mobile devices, an application was designed by using MIT Inventor to create an application interface between robot and mobile devices. While for the robotic arm will be design by using Autocad software. In addition, robotic arm will also use four servos to move.

Abstract: One of the most common problems with modular implants is that they begin to loosen over time. Implant loosening issue is of concern to physicians since implant revision surgery is an extremely difficult operation. A stable fixation between modular taper junctions is necessary to prevent motion and corrosion. There are many factors that can affect the loosening problem. This study aimed to determine the influence of surface roughness and taper angle on junction strength of modular biomedical implant in two different compression forces including 1500N and 2500N. The study was carried out on three different taper angles including 2°, 4° and 6° and surface roughness ranging from 1 to 4.18µm, to keep track of changes in pull out force. The results obtained in this study demonstrated that taper angle and surface roughness affect the pull out force. The highest pull out force was observed at smoother surface roughness and tighter taper angles, declining gradually in rougher surfaces and drastically in wider taper angles. It can be inferred that implants are less likely to be loosened in 1.04µm surface roughness and taper angle 2° considering the scope of experiments.

Abstract: Efforts to optimize the use of silicon rubber and epoxy resin as an insulating material in the electricity sector continues to be done where one of them is looking for filler are cheap and easily obtained. So in this paper is described about the use of coal fly ash as filler for silicone rubber and epoxy resin, where it is known that fly ash has a very fine particle size that is potentially as filler. Utilization of coal fly ash as filler will help solve problems in the field of environment in Indonesia because these materials as a hazardous waste. So as to determine whether the fly ash can improve the performance of silicone rubber and epoxy resin, it has carried out research on the performance characteristics of silicone rubber and epoxy resin that are conditioned on the wet environments that were simulated by immersion in water for 21 days. Parameter measurement that has been observed is the contact angle, the weight of the test material, and the relative permittivity. The results obtained are fly ash allowed to function as a filler in silicone rubber in wet environments due to the difference in the average value of measurement results between silicone rubber without filler (SRFA0) with silicone rubber which has a filler (SRFA30) ie for a contact angle of 1.3°, weight gain 0.2%, and the relative permittivity of 1.4. While on epoxy resins, fly ash is less possible is used as filler in wet environments, because difference between the average value of the measurement results between the epoxy resin without filler (EPFA0) with epoxy resins which has a filler (EPFA30) ie to the contact angle of 4.7°, the weight gain of 4.6%, and the relative permittivity of 4.8.

Abstract: Glass fiber reinforced aluminum laminates (GLARE) are main important types of fibre metal laminates composite material. The composite sandwich is manufactured by inserting glass fibre composite laminate between two chemically treated aluminium thin sheet. GLARE material is manufactured with three stacking sequences using random mate layered glass fibre of 1, 2, and 4 layers. The strength and failure of mechanically fastened glass fiber aluminum reinforced epoxy (GLARE) joints are experimentally investigated. The results indicate that bearing strength of GLARE increases with increasing number of glass fiber reinforced laminates but with limitation of that thickness not largely increasing to avoid delamination. Modes of failure for the bolted joint are enhanced to bearing modes for all types of specimens.

Abstract: Biodiesels produced from vegetable oils are an attractive alternative fuel which are renewable and offer significant reduction of carbon monoxide and hydrocarbon emission due to higher oxygen content. Biodiesels can be easily mixed with petroleum diesel to form blends, and is free of sulphur. Emission control has become one of the most important challenges in diesel engine. The main drawback of use of biodiesels in diesel engines is its higher NOX emissions. The aim of the present work is to reduce NOx emissions of a diesel engine fueled with cotton seed biodiesel. One simple way of reducing the NOX emission of diesel engine is by injection delay of fuel in to combustion chamber. This method is effective but increases the fuel consumption, which necessitates the use of more effective NOX reduction technique like exhaust gas recirculation (EGR). Recirculating part of the exhaust gas along with fresh air admission helps in reducing NOX. A single cylinder four stroke direct injection water cooled diesel engine operated with cotton seed biodiesel (CSBD) and petroleum diesel (PD) blends such as 0% (PD), 10% (CSBD10), 20% (CSBD20) and 30% (CSBD30) are used for the present emission and performance study. Different EGR rates such as 0%, 5%, 10%, 15% and 20% are considered for this study. The speed of the engine is kept as constant at 1500 rpm. The performance of the engine in terms of brake specific fuel consumption& brake thermal efficiency and emission characteristics such as oxides of nitrogen, hydrocarbon & carbon monoxide are studied. For all blends reduced NOX emission was observed with EGR. The better engine characteristics were obtained with EGR rate of 15% for all fuel blends. The observations reveal that cotton seed biodiesel with EGR can be used to reduce NOx.

Abstract: The paper presents an analysis of the thermal and Centrifugal effects on the behavior of the acoustic waves propagating in a half space thermopiezoelectric material surface in the framework of linear thermopiezoelectricity including Coriolis and centrifugal forces. The secular piezothermoelastic generalized equations are formulated and mathematical boundary conditions in closed and isolated form are derived. The characteristics of surface waves propagating in generalized piezothermoelastic solid half-space and their dependence upon geometric and physical parameters have been investigated. It is shown that the Rayleigh and Bleustein-Gulyaev waves, depending of thermal and physical properties of material, can be suppressed by rotation, and are generally dispersive. However, like in piezoelectric half space, there is certain abnormal dispersion for small rotation perturbations and the Coriolis and centrifugal forces on dispersion are generally of the same order. The pre-heating temperature of the material, thermomelastic and pyroelectric coupling effects have not to be neglected. Using PZT-6B as a thermopiezoelectric model material, Numerical and results are generated, simulated and commented.

Abstract: The aim of this work is to find the relationship between EMG, MMG and AMG during muscle fatigue. To achieve the goal of this work, 3 different myograms (EMG, MMG and AMG) were recorded from the biceps femoris during the isometric contraction using bipolar surface EMG electrodes, accelerometers and cardio microphone. Nine statistical features were extracted from time and frequency domain. The extracted features were tests using Pearson Correlation and Linear Regression, to find the relationship between the features and behavior of the feature due to muscle fatigue. Based on the Pearson correlation result, there are relationships between these 3 myograms. In this paper, we also have discussed the behavior of myograms due to muscle fatigue.

Abstract: Flight test is conducted to prove performance required. Aircraft development engineers or flight test engineers use visualization tools for flight test to monitor aircraft performance in Flight Telemetry Ground Station. Thereafter, telemetry flight data are analyzed by analyzing tools after flight test. Conventional systems used for flight test record the real time flight data into certain storage medium based on file. Thus, to analyze data after flight test, complicated steps of download and import process are needed. In this paper, two kinds of systems based on database are designed and implemented for flight test. Suggested systems provide useful visualization tools that monitor performance of the aircrafts and designed to store real time telemetry data into database during the flight test. Also, proposed systems are designed to analyze flight test data easily in various search conditions and to revisualize the same situations of past flight test immediately by using. Some tools of the suggested system are already in use in the field of flight test and more tools will be applied.

Abstract: In this paper, we consider an annular space filled with air (Pr = 0.7) confined between two horizontal coaxial cylinders differentially heated, with a radii ratio R = 2. The space is fitted with two symmetrical heating blocks with a height h = 0.093 and a width l = 0.109 placed at the angular position φm = 0.82π. We investigate numerically the impact of different initial fields on the final solution obtained for a range of Rayleigh numbers between 103 and 104. The obtainment of a bicellular flow regime that promotes the overall heat transfer rate is ensured at different intervals of Rayleigh numbers. Each interval is characterized by specific Rayleigh numbers of the bicellular flow appearance and disappearance depending on the introduced initial fields. These initial conditions have a real influence on the computation time necessary to obtain the optimal steady regimes.
