A Sensor Network is the primary source for acquiring information in today's military operations that require situation awareness (SA) of a battlefield. There are several types of sensor nodes, and each type of sensors has limited capability. The requirement for gathering and analyzing information about the field cannot be fulfilled by one type of sensor. Several sensors are needed to be networked and provide distributed sensing in such the way that the complete information about the field can be achieved. With current sensor and wireless technologies, a large number of heterogeneous sensor nodes can be rapidly deployed and wirelessly networked in a battlefield. These sensor nodes can perform distributed sensing tasks in collaborative and cooperative manner in order to extract features of the event in the field. Unlike any typical network, military wireless sensor network is operating under the harsh condition of a battlefield. Hence, the resources are constrained in terms of energy, bandwidth, and computing power, which limit the sensing capability of the wireless sensor network. In addition, a network is prone to attack by enemies. Such a network requires the self-adaptability that can cope with intermittent changes in a harsh environment. This paper presents a survey for adaptive hybrid wireless sensor networks in the military operations, which reviews their technologies, applications, constraints, architectures, and challenges. © 2016 IEEE.

Wireless power transfer system using a microwave active phased array was developed to transmits of electrical energy from a power source to an electrical load without artificial interconnecting conductors. A microwave power beam consists of transmitting and receiving systems. In this paper, a synthesis horn antenna was design for high power microwave applications. The horn antenna was extended to increase the gain and power to focus the beam. A horn antenna operating at 2.45 GHz is designed and simulated. Measurements show that the horn has a high gain and suitable in the field of high power microwave applications. © 2016 IEEE.

This paper surveys, reviews and describes an airbase (an airport) protection system and airport surveillance system based on wireless network and surveillance technology. The goal of this paper is to present the proposed airbase protection system in terms of ground surveillance that increases the performance, efficiency and capability to the system and users (such as soldier, officer, air traffic controller etc.) by using Long-term Evolution (LTE). The commander can manage, resolve and decide the situation awareness to protect the critical incidents. If the accidents occur, it will affect the stability of military, airbase, population and country. Furthermore, this paper shows that the current trend is to provide wireless sensor networks, multi cameras and airport security checkpoints. © 2016 IEEE.

In recent years the data mining is data analyzing techniques that used to analyze crime data previously stored from various sources to find patterns and trends in crimes. In additional, it can be applied to increase efficiency in solving the crimes faster and also can be applied to automatically notify the crimes. However, there are many data mining techniques. In order to increase efficiency of crime detection, it is necessary to select the data mining techniques suitably. This paper reviews the literatures on various data mining applications, especially applications that applied to solve the crimes. Survey also throws light on research gaps and challenges of crime data mining. In additional to that, this paper provides insight about the data mining for finding the patterns and trends in crime to be used appropriately and to be a help for beginners in the research of crime data mining. © 2016 IEEE.

ASEAN Community is one of the fastest growing economic in the world despite being relatively peaceful and stabilized, the region is one of the global most lucrative defence market. The majority of state promotes and develops some degree of defence industry capability, driven by a number of motivations. This paper examines the motivations behind the defence industry development to be economic growth, threat to national security and sovereignty, Technology capability, self-reliance and finally, wealth. It underlines the importance of license production, FDI, joint venture, offset technology and knowledge transfers to the development and sustainability of defence industry. It also categorizes member states into tiers grouping based on technological capacity previously defined by Keith Klause, Andrew Ross and Richard Bitzinger. Finally, it provides a brief overview of ASEAN defence industry landscape, describes the current industrial capacity and R&D activity. © 2016 IEEE.

This paper uses wing characteristics from the Half Scale Unmanned Arial Vehicles (UAV) designed by Defence Technology Institute (DTI). It also demonstrates results from both plain wing and wing fitted with VGs simulation using a commercial Computational Fluid Dynamics (CFD) program. VGs designing processes (sizing and installed position) are also designed according to historical data. Furthermore, six different VGs configurations are tested to find effects to the wing aerodynamics. Stall angle, lift coefficient (CL), and drag coefficient (CD) are obtained through CFD, and they will be discussed. © 2016 IEEE.

Mathematical theory of fractional calculus has applied to study many fields of physical science recently. In this paper, this theory has applied further to study on mathematical model of arms race proposed by Saperstein. The model is in the discrete form of couple logistic equations. This type of dynamical system may provide key to understand complex behaviors in social and political science in term of nonlinear dynamics. The conflict event that leads to outbreak of war can be identified as the transition to chaotic state in dynamical system. The dynamical behaviors of the arms race model explain by phase space. The numerical calculations of the arms race model have presented their fractional-order state behaviors. © 2015 IEEE.

14.5 AP Ballistic impact on armor steel was simulated to investigate the effect of material and obliquity on ballistic resistance performance. The research was conducted with explicit dynamic code and AUTODYN on ANSYS commercial software. The result revealed that single layer of 10 mm V250 steel could not defeat 14.5 mm AP bullet. The second layer of alumina ceramic on V250 steel can increase ballistic resistance of V250 steel and leads troop survivability. © 2015 IEEE.

Ferrocene (Fe(C5H5)2) is an organometallic compound which its structure consists of two cyclopentadienyl (Cp) rings bound on opposite sides of a central metal atom. This compound is usually added into rocket's solid propellant as a burning rate catalyst. However, this composition always migrates from the propellant system by both diffusion and surface migration mechanism that causes the unpredictability of the burning rate which in turn renders unpredictable rocket performance Therefore, the study of the method to investigate the role of Ferrocene in biological systems is highly significant. This paper proposes the use of molecular simulation to study the properties of Ferrocene molecular systems to get a deeper understanding of the physics of electronic correlation in real materials. The result from the studies shows that Gaussian and Monte Carlo is the suitable method to simulate the role of Ferrocene in biological systems. © 2015 IEEE.

Static test is the important test for demonstrate the efficiency of propellant. The test is imperative for any batch of propellant. In the past, researcher used normal steel case in this test for only one time, because the test made the steel case damage into the steel grain from high pressure and temperature. Even though, the high corrosion condition from the vapor of chemical after burst. In that case, the steel case can be a higher cost. Therefore this paper aspires to recondition this problem by changing to new material. Austenitic stainless steel is the proper material that we choose, the prominent corrosion resistance in high temperature. 316L grade addition some of elements such as Cr and Ni is the new condition that we use in the research. Chromium can improve the corrosion resistance and the Nickel improves the higher strength of the case. So after static test, the new material case has the better grain, less inter-granular problem and get a smaller size of grain. Changing the better grade of the material can get higher cost, whereas better material can be reused the case more than two time. So that way can reduce the cost and scrap from static test. © 2013 TANGER Ltd., Ostrava.
