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. Source

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. Source

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. Source

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.
