High resistive β-tungsten has been recently shown to exhibit a giant spin Hall Effect, which can be utilized to control the magnetization state of an adjacent magnetic layer [1–3].
Mass failures of slope, which includes movement in soil, rock, ice which cause a considerable damage to the natural habitat, environment, economy and other resources. Detection, monitoring and control are the three major issues regarding Real-Time applications. For a large scale detection of fault and monitoring the faults is one of the important applications that lead to advancement of many kind...
Service-oriented computing enables service providers to publish their business functionalities in the form of abstract contracts, which can be discovered by service consumers based on open and standard protocols. Enterprise may be running a number of multiple business processes in parallel, which may require different services to fulfill the functionality. To provide better search, query, composition,...
Motion estimation is a well-studied problem and researchers are coming up with new algorithms. The aim of this paper is to implement a motion estimation algorithm on a embedded device and to evaluate the performance. For this purpose a Texas Instrument TMS320DM642 evaluation module with TVP video decoder is being explored, and motion estimation algorithm based on ??Three Step Search?? is to be implemented...
Event-drive business processes require integration with distributed heterogeneous services to fulfill the functionalities. Business processes run in parallel and interact with multiple services, partners and customers as per the requirement and policy. There is a need to aggregate information from multiple resources or services according to policy. Resource or service aggregation provides better query,...
This paper presents a multimodal biometric recognition system integrating palmprint, fingerprint and face based on score level fusion. The feature vectors are extracted independently from the pre-processed images of palmprint, fingerprint and face. The feature vectors of query images are then compared individually with the enrollment templates which are taken and stored during database preparation...
Modern data centers use virtual machine based implementation for numerous advantages like resource isolation, hardware utilization, security and easy management. Applications are generally hosted on different virtual machines on a same physical machine. Virtual machine monitor like Xen is a popular tool to manage virtual machines by scheduling them to use resources such as CPU, memory and network...
Wireless sensor networks are application specific,data centric networks where different applications run on deployed network. Each application interprets the underlying sensor network differently and each changing event has different effect on running applications.In this paper we have proposed context aware middleware architecture called as 'MidSen'. This architecture bridges the gap between multiple...
The aim of service discovery is to discover services based on preferences given by service consumers. Many approaches are using keyword based syntactic methods and recent approaches are using semantic Web technology to enhance service discovery. Traditional service discovery mechanism acts like a black box which processes input and gives output. Results of service discovery are not based on current...
There have been numerous nanowire crossbar architectures proposed till date and they are envisioned as clock-driven. To deal with numerous issues caused by clocking, a new asynchronous architecture based on Null Convention Logic (NCL) has been recently proposed, resulting in the removal of the clock circuit overhead from the crossbar architecture. The proposed architecture is easier to be manufactured...
Wireless communications has witnessed a tremendous growth during the past decade and further spectacular enabling technology advances are expected in an effort to render ubiquitous wireless connectivity a reality. The first step towards high speed digital communication over a wireless media includes the understanding of the channel and its characteristics. In a wireless media we have multipath components...
Discretization of continuous valued features is an important problem to consider during classification learning. There already exist a number of successful discretization techniques based on LVQ algorithm. In this paper, we have approached the problem of discretization from a different angle, and have proposed an algorithm based on optimization of Learning Vector Quantization (LVQ) with Genetic Algorithm...
Grid is a collection of distributed computing resources that performs tasks in co-ordination to achieve high-end computational capabilities by dividing a given task into sub-tasks. Each sub-task could be large and run for several hours or days on a number of grid nodes. If a sub-task fails to complete even on a single site, all the computations should be performed again. In scalable distributed systems,...
In order to meet rapidly changing business needs, organizations need business processes that can be flexible and agile to adapt to these changes. This would require dynamic composition of services. Composition of services requires dynamic discovery of services and dynamic selection of service end-point. Service discovery and selection depend on metadata, policy and event associated with these business...
Business processes are event-driven and required set of tasks to be executed to fulfill the goal. Event-driven business process model by representing process as conceptual process flows. Business process required composition of services and execution of services as per the event. Events are responsible to change the state of process so we can model the business process based event and state. Web services...
One of the important aspects in digital video applications is spatial and temporal characteristic. A very little progress has been achieved on spatio- temporal modeling of video data. In this paper, we present a fuzzy spatio-temporal model for video content description that supports spatio-temporal queries. Fuzzy definitions and membership functions of temporal relations are given and second order...
Grids are used extensively for scientific research and computationally intensive business processes, as they provide a wide range of resources for use to its participants. Collaboration and resource sharing form the basic ideologies of a grid, hence it becomes imperative that joining and leaving the grid becomes easy and any independent network of resources can collaborate with other operational grids...
There have been numerous nanowire crossbar architectures proposed till date, although all of them are envisioned to be synchronous (i.e., clocked). The clock is an important part in a circuit and it needs to be connected to all the components to synchronize their operation. Considering non-deterministic nature of nanoscale integration, realizing them on a nano wire crossbar system would be quite cumbersome...
Co-operative task execution amongst multiple agents is an important field for research today. In this paper we study a system for surveillance in an open environment using multiple sensor-enabled robots. These robots can detect and track a target using their sensors. Robots/Agents can also communicate amongst each other to coordinate in task execution. Agents maintain lists of (a) targets within their...
Due to advancement in grid technologies, resources spread across the globe can be accessed using standard general-purpose protocols. Simulations and scientific experiments were earlier restricted due to limited availability of the resources. These are now carried out vigorously in the grid. Grid environments are dynamic in nature. The resources in a grid are heterogeneous in nature and are not under...
