The analysis of lateral stability of tailless CAMAR-3 with winglets

This paper analyses the lateral stability of tailless CAMAR-3 Unmanned Aerial Vehicle (UAV) when its tail fin (i.e. V-tail) is reconfigured to the wingtips. A tailless UAV may have longer endurance time, compared to the present configuration of V-tail. Nevertheless, a tailless UAV may experience reduction in lateral stability due to loss of yaw control surfaces. In the preliminary design of tailless-winglets UAV, semi-empirical method is applied to estimate the aerodynamic lateral stability derivatives, in order to investigate the stability of both configurations of UAV. ThenThen, a dynamic test rig based on pure yawing motion is built, to measure the lateral stability derivatives of C_(n_β ) and C_(n_r ) in transient conditions. The time response data of pure yawing oscillation give the natural frequency and damping ratio that describe the aerodynamic derivatives as a result from wind-on and wind-off tunnel tests. The result indicates that UAV with either configurations are laterally stable. However, the tailless-winglets CAMAR has a 13.86% reduction in aerodynamic yawing-moment-due-to-sideslip derivative C_(n_β ), compared to CAMAR-3 with V-tail; whereas the aerodynamic yawing-moment-due-to-yaw-rate derivative C_(n_r ) of tailless-winglets CAMAR is 5.55% lesser than that of the CAMAR-3 with V-tail. The lateral stability degrades, as expected, caused by tail stabilizer removal. In conclusion, the idea of tail removal and using winglets as the directional controllers is feasible

Vapor pressure development in a FR4-CU composite structure during solder reflow

This article presents a study on the development of vapor pressure a FR4-Cu composite structure when heated to a solder reflow temperature of 215 °C. Abaqus® finite element software was used to develop a representative two-dimensional model of the composite structure and to simulate moisture absorption and desorption processes. Simulation of transient moisture absorption was performed to predict moisture concentration distribution in the structure after being preconditioned in 85°C/85 % RH environment for 15 days. Simulation of transient moisture desorption was carried out at the solder reflow temperature to predict the redistribution of the moisture. Results of the moisture desorption simulation were used to compute magnitude of the vapor pressure in the structure. It was found that the moisture redistributes itself during the solder reflow process. Moisture concentration in the vicinity of the FR4-Cu interface, below the longer copper trace increases during the solder reflow. The vapor pressure in nearly 70 % of the FR4 material and close to the FR4-Cu interface, below the longer copper trace is almost equal to the saturation pressure of vapor at 215 °C. Distribution of the vapor pressure is very similar to the new distribution of moisture concentration resulting from moisture desorption process

Upgrading for overhead crane anti-sway method using variable frequency drive

The paper discusses about upgrading the overhead crane anti-sway method base on the induction motor torque control from rotor resistance starter to variable frequency drives (VFDs). The upgrading included two phases. The phase 1 is to identify the performance of the overhead crane operation on anti-sway method base on the induction motor torque control using rotor resistance starter (old existing motor starter). The phase 2 is to identify the performance of the overhead crane operation on anti-sway method base on the induction motor torque control that use a variable of frequency drive (new upgrading motor starter). The primary equations connecting tractive force and load sway angle, which the motor torque control law is based on is designed for 0% load wobble at the end of the journey. The words accelerating and braking have been written. Outcomes of modelling the behaviour of a trolley-load of two masses for the normal overhead crane load ratios, a system is described weight to the length of the rope, which supports the hypothesis concerning the feasibility of direct load anti-sway control ON and OFF for regulation of motor for overhead cranes

Antimicrobial susceptibility pattern and distribution of ExoU and exoS in clinical isolates of Pseudomonas Aeruginosa at a Malaysian hospital.

This study was conducted to determine the antibiotic susceptibility pattern and distribution of exoU and exoS among 44 clinical isolates of P. aeruginosa collected from different patients over a 3-month period in 2010 at a major Malaysian hospital. Susceptibility data by disk diffusion method for cefepime (30 μg), ceftazidime (30 μg), gentamicin (10 μg), piperacillin-tazobactam (100/10 μg) and ciprofloxacin (5 μg) were available for 38 isolates. Resistance to ceftazidime and piperacillin-tazobactam was the most common (74%) with five isolates not susceptible to three or more different antibiotics. PCR detection of exoU and exoS of all 44 isolates showed the former gene to be present in 18 and exoS in 41. In analyzing the two genes together, 17 isolates were detected for exoU and exoS with only two being negative for both genes. Only one isolate was detected for exoU alone whereas 24 for exoS alone. Distribution of the genes in relation to antibiotic susceptibility was inapplicable due to the majority of the isolates having similar susceptibility patterns, but the tendency of exoU-carrying isolates to be present in male patients (83%) and respiratory sites (61%) was observed (p < 0.050). The finding warrants further investigation in a larger sample of isolates

An Analysis of the Institutional Framework of the Commercial Vehicle Rebuilt Industry in Malaysia

Rebuilt industry, also known as remanufacturing, is the practice of taking end-of-life goods and reengineering them back to as new or better condition. In Malaysia, one of significant remanufacturing activities is the automotive remanufacturing or rebuilt commercial vehicle industry. The industry has begun since 1970s, the time when the construction sector was booming. Despite of its importance in bringing to a sustainable development of a country, no studies have been conducted on the effectiveness of the practice in Malaysia. However, the recent problematic issue surrounding the industry has led to the call for this research. The purpose of this study is to explore the effectiveness of the institutional framework of the commercial vehicle rebuilt industry in Malaysia. The results obtained were based on seventeen interviews. All interviews were transcribed and the data were analysed using the content analysis method. The results demonstrated that with the present practice of the institutional framework allows some loopholes within the industry. These loopholes have led to the production of false document and thus excessive number of rebuilt commercial vehicles registered, far greater than the quota given by the Ministry. This issue arose due to unavailability of effective communication mechanisms among the relevant government authorities. This study provides insights into the strengths and weaknesses of the present governance in dealing with the rebuilt commercial vehicle industry in Malaysia. It is important as it opens up various issues that have been lingering within the implementation of the industry.rebuilt industry, automotive remanufacturing, interviews, governance

Case Study of Engineering Ethics toward Natural Gas Pipeline Leaking: An Analysis through Solving Technique

This paper focuses on the case study of engineering ethics for Gas Pipeline Explosion at Ghislenghien, Belgium. The tragedy happened on 30th of July, 2004 and investigation was conducted to find the root cause. However, the question is remains unsolved. Investigators and experts listed few reasons that may affecting the gas pipeline including safety regulations not being observed due to deadline given is too short, soil erosion and used of mechanical diggers within one meter of the gas pipe. Rescue operation was initiated immediate after the gas explosion. This tragedy causes 24 dead including 5 fire fighters and indicated an amount of 100 million euros lost and lead to multiple reformation. Therefore, a case study of engineering ethics has been done and the analysis has been made in terms of ethical framework and ethical theories respectively. The recommendation of this study is hoped to help the engineers in order to reduce the numbers of accidentin their work place

Identification of sharp edge non-slender delta wing aerodynamic coefficient using neural network

Delta wing formed a vortical flow on its surface which produced higher lift compared to conventional wing. The vortical flow is complex and non-linear which requires more studies to understand its flow physics. However, conventional flow analysis (wind tunnel test and computational flow dynamic) comes with several significant drawbacks. In recent times, application of neural network as alternative to conventional flow analysis has increased. This study is about utilization of Multi-Layer Perceptron (MLP) neural network to predict the coefficient of pressure (Cp) on a delta wing model. The physical model that was used is a sharp edge non-slender delta wing. The training data was taken from wind tunnel tests. 70% of data is used as training, 15% is used as validation and another 15% is used as test set. The wind tunnel test was done at angle of attack from 0°-18° with increment of 3°. The flow velocity was set at 25m/s which correspond to 800,000 Reynolds number. The inputs are angle of attack and location of pressure tube (y/cr) while the output is Cp. The MLP models were fitted with 3 different transfer functions (linear, sigmoid, and tanh) and trained with Lavenberg-Marquadt backpropagation algorithm. The results of the models were compared to determine the best performing model. Results show that large amount of data is required to produce accurate prediction model because the model suffer from condition called overfitting

Optimizing the parameters in durian skin fiber reinforced polypropylene composites by response surface methodology

Awareness on the advantages of natural fibers stimulates the interest of researchers to use them as reinforcement in polymer composites for robust application. Therefore, investigation on optimizing the impact property of durian skin fiber (DSF) reinforced polypropylene (PP) composites was carried out to determine the effect of DSF content, fiber size and maleic anhydride polypropylene (MAPP) content. Response surface methodology (RSM) was used in the design of experiments and in the analysis of results. The optimized value for the maximum impact strength of PP–DSF composite was found at 50 wt% DSF content and fiber size range of 250–500 μm with 0 wt% MAPP. The maximum impact property for PP–DSF composite was 10.66 kJ/m2. From the analysis of variance (ANOVA), fiber content significantly affects the strength of PP–DSF composites, followed by the fiber size and MAPP content. The P-value of the model of experiment is less than 0.05 and the determination coefficient (R2) is nearly 1 which suggested that the model is significant and implies on the precision and processability in the production
