The use of Wireless sensor network is to monitor an area for event detection. The sensor node have some limitation like the sensor node associated with battery power and generally it is not possible to recharge or replace battery of sensor due to large number of sensor node, node distribution in remote, desert or hostile areas etc. The energy consumption of sensor node appears a lot of challenges...
This paper presents an approach to enabling rapid design and deployment of small unmanned aerial systems (SUAS) using SysML. Recent advances in SUAS technologies have uniquely situated these systems to provide battlefield situational awareness and operational support to the U.S. Army. However, off-design mission performance is often highly degraded due to the small scale of the vehicles. Previous...
Human face is an important object in an image database due to its unique features (eyes, mouth, nose etc.) in every human being. The detection & recognition of a face in an image using template matching is one of the profound research interest in the field of image processing. Various approaches have been proposed in the literature to extract the visual facial features based on texture, color,...
A simple, rugged and accurate Flight Profile Simulator (FPS) for launch vehicle hardware and software real-time testing is proposed in this paper. The launch vehicle onboard system is a MIL-STD-1553B based configuration with Onboard Computer (OBC) as Bus Controller (BC) and Navigation, Sequencing and Control subsystems as Remote Terminals (RT). The simulator acts as another RT on the 1553B bus and...
Wireless Sensor Networks is an emerging technology in the field of communication. Wireless sensor nodes provide real observed data from the different environmental conditions and provide data for monitoring and controlling the systems. WSNs are suitable for various applications such as intelligent surveillances, border security and disaster management by gathering remote data about surroundings either...
The major challenge in wireless sensor networks having limited resources is to maximize the network lifetime and coverage level. The effectiveness of sensor network operation depends significantly on the level of coverage achieved. The coverage level depends on the sensing capability and quality of the data transmitted. The sensor coverage models are abstraction models which measure sensors' observation...
Graduates are expected to be skilled across disciplines and provide holistic solutions. Hence, scaffolding is crucial as transfer of learning does not occur naturally and teaching-learning strategies found to be effective for experts may not be adopted similarly for novice learners. We hypothesize that if we can help students to model in relation to the ecosystem, they should be able to identify or...
Graduates are expected to be able to provide holistic solutions, capable of meeting diverse objectives simultaneously. Furthermore, opportunities are often “found” or “made.” The quality of solutions, however, is mediated by different conceptualizations of contexts. Thus, we aim to investigate how students would conceptualize, make sense, desire to know, find solutions and subsequently progress to...
Wireless communication technology and the electronic systems advancements have laid the foundation of the wireless sensor network which achieves the growth of low-cost, low power and multi-functional sensor nodes which can be deployed on a single chip to communicate over a short range. The sensor node consists of sensing elements, actuator and a limited source of energy as battery. The major problem...
Wireless sensor network is a network consists of large number of sensors and a base station. There are many novel architectures, algorithms, protocols implemented so far but one of the major issues in wireless sensor network is to develop an energy efficient routing protocol which affects the stability and overall lifetime of the network. Clustering of nodes is one of the effective techniques used...
Wireless sensor network (WSN) consist of spatially distributed self-sufficient sensors nodes. Energy is the main bottleneck for wireless sensor networks and it has dominating effects on network lifetime. The Clustering is considered one of the powerful approaches for maximizing the life time of a wireless sensor network because of their better scalability and higher energy efficiency than other routing...
As e-Banking has become one of the most widely used method of banking, the security risks caused by attacks on the e-Banking systems have also become imminent. The consequences of these attacks can be dire and most banks have been trying to keep the risks low. In order to be trusted and used by the customers, information confidentiality, integrity and availability have to be maintained. This paper...
Nowadays, the development of cloud computing tends to be fast and rapid in our Internet environment, especially in the field of information technology which involves high demands on large scale of network-computing. Cloud computing aims to obtain the benefit in sharing of resources, economies of scale with great production and better adjustment of the network resources. It brings much more challenging...

The existence of Internet, communications and information technologies, combined with recent Micro Electro Mechanical System advances, is leading the way for a new generation of low-cost sensors and actuators, which aim to achieve a high degree of spatial and temporal resolution and accuracy. The autonomous nature of sensor networks makes it of significant importance in various hazardous application...
A major hope of education is that students will be able to transfer what they have learnt to other similar situations and their everyday lives. However, transfer is not a given. Often, it does not happen. This case study refers to findings from Engle's (2006) study on the role of framing in explaining why and how transfer occurs to investigate whether framing can serve as a mechanism for scaffolding...
A MANET is a collection of mobile nodes communicating and cooperating with each other to route a packet from the source to their destinations. A MANET is proposed to support dynamic routing strategies in absence of wired infrastructure and centralized administration. In such networks, limited power in mobile nodes is a big challenge. So energy efficient techniques should be implemented with existing...
New complex and Low Power systems are being implemented using advanced Electronic Design Automation (EDA) tools. Low power designs are not only used in small size applications like mobile phones, tablets and handheld devices but also in high-performance computing applications. As the complexity increases day by day, the dissipation of power has emerged as one of the very important design constraints...
In the design of traditional systems, the estimation of the initial economic viability and technical feasibility of a concept were the primary outputs of preconceptual and conceptual design. With a shift towards the system of systems, the estimation of economic viability and technical feasibility of the proposed system of systems becomes more complicated since each stake holder's perspective must...
In this paper we propose distributed algorithms that solve the coverage problem in 3D space. In particular, we use a swarm of unmanned aerial vehicles (UAVs) in order to explore a possibly unknown area. Actual use cases include the automated acquisition of sensory data in operations that try to gain extensive knowledge about an area. First, we try to efficiently cover a predefined 3D space with multiple...
