Published: July 2018

Radio communications do not work only in the air and underwater, but also underground. Some applications such as mining and earthquake detection require underground radio devices. This paper reports an assessment of underground radio characteristics for frequency band 97 MHz to 130 MHz. The assessments were performed through an experimental propagation measurement and a mathematical prediction. Both assessments then are compared by using the normalized graph to predict propagation characteristics so that correct link budget for future application can be assisted. The mathematic analysis and measurement results still produce huge errors; achieving 50.33% for frequency 130.762 MHz, 17.58% for 109.818 MHz and 13.38% for 97.335 MHz. Error can be minimized when the ground permittivity is more precise

Authors: N A Prashanth. , Sujatha P
Published: July 2018

This paper proposes application of Genetic Algorithm (GA) and Particle Swarm Optimization (PSO)   in the design of direct-driven permanent magnet synchronous generator machine (PMSGs) for wind turbine applications. The power rating of these machines is in the mega watt (MW) level. The constraints and requirements of the generator are outlined. The proposed design scheme optimizes various PMSG parameters like Pole pair number, Linear current density, Air gap thickness, Rotor outer diameter, Relative width of the permanent magnet  etc to achieve certain objectives like maximizing efficiency, increasing Torque, improving power factor etc. The results obtained by GA algorithm and those by PSO algorithm are compared.  The performance of Particle Swarm Optimization is found to be better than the Genetic Algorithm, as the PSO carries out global search and local searches simultaneously, whereas the Genetic Algorithm concentrates mainly on the global search. Results show that the proposed PSO optimization algorithm is easy to develop and apply and produced competitive designs compared to the GA algorithm.

In the past many research have been carried out to grasp the mechanism of failure of beam-column joint and methods to enhance the performance of beam-column joint have been developed. The provision of ductile detailing as prescribed in IS-13920: 1993 has been followed. Improvement of the performance of joint region has been studied by using additional reinforcement with different fibres. In the present study the performance of the BC joint is studied in terms of load vs. displacement curve, stiffness degradation vs. drift angle curve and energy dissipation by the BC joint using different types of fibres in the specimen. The laboratory testing of the concrete cubes and cylinders reinforced with different percentages of fibre volume have been implemented. Based on the test results, the selection of the optimum quantity of fibre that can be used in beam-column joint for each type of fibre has been done. The testing of the specimens of BC joints is carried out in cyclic actuator of capacity 100 kN. The fibres which have been used in the present study are carbon fibre, steel fibre and glass fibre. Percentages of the fibres that had been added to the specimen are carbon fibre (0.75%), steel fibre (0.75%) and glass fibre (0.50%) respectively and the control specimen made from ordinary concrete made of M25 mix concrete. The performance of the specimens reinforced with different type of fibres is then compared and the specimen showing desirable performance under cyclic loading is found out. It has been observed that the application of carbon fibres could improve the strength and ductility of BC joints appreciably.

Authors: M. Jyothsna K , Suganthi S
Published: July 2018

This paper portrays the design of a compact square-shaped microstrip broadband antenna using ground slots. Polygon shaped slots are placed on the ground under the feed line for bandwidth improvement. Similarly, rectangular slots are placed on the square patch for gain enhancement. Effect of these slots on the performance of the antenna in terms of impedance bandwidth, gain and directivity are studied.  Results of simulation tests show that a ground slot with proper dimensions placed under the feed line can improve the impedance matching and hence increase the bandwidth without affecting much the performance of the antenna. This compact antenna of size 9.098 x 9.098 mm can be very useful for applications where size is a major constraint. Simple microstrip feed is used to feed the patch. The percentage bandwidth of this antenna is 75.57 %.

Efficient Multilevel Privacy Preserving Authentication Scheme for Emergency Message Communication in VANE
Authors: Santhana Devi G , Germanus Alex M
Published: July 2018

Vehicular ad hoc networks (VANETs) provide spontaneous traffic related and emergency rescue messages to its users of the route thereby enable them with the trouble-free driving. VANETs send emergency messages in times of exigencies that save people’s lives from disasters. Doing such times it has been a great challenge to ascertain the authentication and privacy of the messages that are broadcasted. Generally when the messages are broadcasted without accommodating privacy the confidential information’s like the vehicle’s id and location are exposed which adversely affect the users. In this paper to ensure privacy to the users we have recommended TA to provide a verification signature to all the vehicles which is mandatory for a vehicle for all its communication purpose. Normally in the existing schemes, the messages are provided with single level or bi level privacy features but, in the proposed scheme the emergency messages are provided with the multilevel privacy features. In the proposed scheme the TA provides a long term  Verification signature which is mandatory to all the vehicles that are registered under VANET and this signature is also necessary in receiving the secondary token and common token from RSU at each interval of time. The authentication of the message is verified with the help of common token and encrypted common token as a RSU Verification signature. Since the emergency messages require secure, timely and factual communication our proposed protocol EMPPA scheme recommend the distribution of multiple verification signatures and tokens at various interval of time, so that the privacy, security and the authentication of messages are ensured to the VANET users.

Authors: Supar Khairi , Hilton Ahmad Hilton
Published: July 2018

Implementation of multi-bolts arrangements in structures connections are commonplace in steel design to allow for joint efficiency and stronger connections. Woven fabric kenaf fibers are potentially used as reinforcement in composite materials due to excellent specific strength, renewability and less hazardous during handling as compared to commercial fibers. A two-dimensional Extended Finite Element Method (XFEM) framework of single-row multi-bolted joints has been developed to study the stress distribution and predict the joint bearing stress at failure. Stress distribution among adjacent bolts were compared along the hole boundary and net-tension plane, suggesting net-tension failure occurred at end-bolt. The predicted bearing strength from finite element modelling are validated against experimental framework.

Flooding is a perennial problem in the Philippines during the monsoon season intensified by the effects of typhoon. On average, there are 20 typhoons that enter the Philippine Area of Responsibility (PAR), and many of these make landfall causing catastrophic aftermath. Extreme rainfall events could lead to flooding in the downstream floodplain and landslide in mountainous terrains. In this study, which is for the case of Calumpang River that drains to the populated and developing region of Batangas City, the focus is on flooding in the floodplain areas. The river was modelled using LiDAR digital elevation model (DEM) that has an accuracy of 20cm in the vertical and 50cm in the horizontal. The result of this is river hydraulic model that can be used to accurately generate flood inundation simulations and flood hazard maps.

In order to achieve sustainable product design process, aspects such of environmental, economic and social should be balanced.  This paper discussed on sustainability of product design, conceptual basis of life cycle assessment (LCA), review of LCA at several product design, methodology of proposed framework and discussion on strengths and limitations of LCA. This paper proposed to develop a framework for improving the product design process based on LCA tool. The aims is to calculate potential impact of environment, economic and social aspects during product design process. For environmental aspects, LCA tool will be used. For economic and social considerations, life cycle costing (LCC) and social life cycle assessment will be applied respectively. At the end, proposed framework are able to help designers to improve product design by considering all sustainability aspects.

Comparison of four different clutter profiles (border, seaside, free space and forest) using Forward Scatter Radar (FSR), which operates in Ultra-High and Very High Frequency (UHF and VHF) bands, is analyzed in this paper. Clutter levels ranging from low, medium, strong and very strong on each profile were studied. Based on the standard deviation of each clutter profile, border suits the best profile as the strongest clutter profile amidst seaside and free space, while the forest is determined as the lowest clutter profile. Subsequently, the characteristics of the clutter are investigated and compared based on the five distribution models (Log-Normal, Log-Logistic, Gamma, Weibull and Nakagami).  The parameters of the five distributions are evaluated using Root Mean Square Error (RMSE) in order to prove that the distribution model fits best to the clutter data. It can be concluded that Gamma distribution is the best distribution model for all cases of frequency bands and profiles.

The objective of this paper is to numerically study the flow feature and combustion phenomena of an energy-saving cooking burner using three-dimensional computational fluid dynamics (CFD). Combustion temperatures were experimentally and numerically investigated in order to not only validate the CFD model, but also describe the combustion phenomena. From the temperature comparison, the CFD model was good agreement with the experiment, having the error of less than 5.86%. Based upon the insight from the CFD model, the high temperature of 1,286 K occurred at the middle of the burner. The high intensive vortex of the flow being enhanced the combustion intensity and the heat transfer coefficient is obvious observed near the burner head inside the ring. Therefore, it is concluded that the burner ring is the major part since it controls flame structure, high temperature region, intensive combustion region, heat loss and suitable flow feature. However, heat transfer to the vessel should be further clarified by the CFD model.

Published: July 2018

Only a few companies in Indonesia have implemented Total Productive Maintenance (TPM) and Lean Manufacturing (LM) properly. They also implemented LM separately with TPM. To look beyond their implementation, a research through survey method will be conducted to identify the status of TPM and LM practices. The data recorded through the survey will be calculated and analysed using Structural Equation Modelling (SEM) with Smart-PLS as a programming tool. The expected results were to provide updated barriers and enablers factors in implementing TPM and LM, to produced reliable CFA (measurement) models for TPM, LM and MP and proposing reference model (structural model) of the relationship between TPM, LM, and MP for manufacturing industries in Indonesia.

Cucurbit family are a fruit producing plants with 130 genera and 800 species and it is one of the genetically discrete groups of food plants such as pumpkin, cucumber, squash, gourd and melon. Cucurbit family provide an important dietary fibre, β-carotene (pro-vitamin A), potassium and vitamin C. Consuming dietary fibre regularly can prevent diabetes mellitus, obesity and cardiovascular disease. Pumpkin (cucurbita maxima) is widely cooked as desserts in Malay cuisines. 60-80% content of polysaccharides in pumpkin pulp functions as anti-tumour, anti-diabetic, hypolipidemic, and immune-stimulating activities. Winter melon (Benincasa hispida) is a source of water soluble polysaccharides, vitamin C while the taste is pleasant, sub acid and aromatic juicy flesh; a great source of functional food production and can be stored up a year. Rockmelon (Cucumis melo L) has nutritional value namely carbohydrates, ascorbic acid, folic acid and potassium while the seeds are rich in oil and protein, and the compounds of this fruit are functioning to prevent cancer, fighting depression, dandruff, ulcers and stimulate the immune system. The red flesh of watermelon (Citrulus lanatus) has anti-carcinogenic compounds. Cucurbit fruits have blood glucose lowering properties and the active ingredient has been shown to be polysaccharides; able to modulate the immune system, anti-tumour, decrease inflammation and act as hypoglycaemic agent.

Mangroves are important coastal resources that provide both tangible and intangible benefits to the locals as well as others. Rapid coastal development pressures the mangroves to decline continuously. The objective of the study was to comprehend the perception of the locals on mangrove change issue and also to analyze the differences of perceptions among selected socioeconomic factors. Research conducted with a questionnaire survey with 5 point likert type answering options among 196 local respondents from three mukims namely Jelutong, Tanjung Kupang and Serkat. Mean perception score was 3.67 which indicated respondents agreement with the mangrove change issue. The Anova shows the perception score significantly differed among different age groups however there was no difference of perceptions among the rest variables such as race, marital status or education level. The findings of the study concluded that regardless of socioeconomic factors (except age) the respondents were concurred with the situation of mangrove loss in the studied mukims.
