The development of service computing technology has triggered the need for organizations to build a service computing system. This system is able to deliver IT services that can meet the challenges and needs of business services. An understanding of the service computing systems engineering life cycle is necessary to model and build the systems. This paper conducts the study of the service computing...
Instruction set simulators (ISSs) play a critical role in the design cycle of embedded systems. However, as ISSs evolve and increase in complexity, not only new bugs might be introduced but also old latent bugs might be revealed. Finding these bugs based on the simulator output might be a challenging task. This letter presents HybridVerifier, a novel and retargetable framework for ISS verification...
This paper introduces the performance analysis of OpenStack Cloud with the commodity computers in the big data environments. It is necessary to analyze the performance of virtual system in cloud infrastructure with the commodity computers to identify effective and efficient system for processing big data. To determine performance measures, virtual systems were created in the Openstack cloud and Hadoop...
Monitoring of the environment is an increasing interest due to the changes in nature. Radio links enable to connect sensing devices in many organizations and ranges. This paper describes a software method for easing exploration of radio link possibilities, taking into account geographical topologies. The software uses massive parallel execution on GPUs and cellular automata in order to compute radio...
The paper presents the development tools for parallel dataflow computing systems that use associative environment for computing process organization. Such tools are organized as the Software complex for dataflow systems development. They allow to assess the operating efficiency of various associative environment implementation variants. They also allow to evaluate the execution efficiency of tasks...
Today's era is cloud era. Maximum organizations already are using cloud services for their data storage and many more looking forward to shift on cloud computing. Data stored on cloud data servers by data owners or organization should be accessible to privilege users. On cloud enormous data is stored but when authorized users wants to access specific data of his interest resource matchmaking is required...
With the development of computing technology, the architecture of healthcare information systems (HIS) may evolve into an application of pervasive computing. HIS requires a more complex high-level design because of its involvement of many different organizations with individual interests and goals. Therefore, an agent-oriented architecture is preferable over other traditional models, such as object-oriented...
Cloud Computing (CC) is a computing infrastructure paradigm that provides elasticity to software or hardware solutions on organizations, and is more powerful than traditional architectures for storage, processing, and distribution of data. Meanwhile, Enterprise Architecture (EA) describes organization's structure and allows assurance its objectives. Recent studies face to integration of EA with CC...
Cloud Computing is a Service Delivery Mechanism. Computing resources are delivered as a service over the network. These services are Scalable, Autonomous, and Cost effective in nature. Cloud Computing is responsible for the exponential growth of IT Industry. In spite of having so many advantages it has various security challenges that cannot be ignored. In order to make the Cloud Computing all the...
In the last years, the Cloud services market experienced an extremely rapid growth, which may lead to severe scalability problems. Therefore, in order to cope with the resource capacity limits of a single Cloud provider, as well as to address the vendor lock-in problem associated to the choice of a single proprietary Cloud solution, the concept of federating multiple heterogeneous organizations is...
Proper trust management in cloud computing environments can significantly assist their widespread adoption. Trust can act as a countermeasure to the several security threats that the cloud faces. This paper provides an overview of how trust has been applied in cloud computing. Trust models suggested in contemporary literature for cloud computing systems are presented. Furthermore, a critical comparison,...
Effectiveness of timing analysis of real-time applications depends on the timing predictability of the underlying execution platform. Modern hardware architectures improve average case performance using complex features. However, these features makeWorst Case Execution Time (WCET) analysis complicated often leading to pessimistic derived worst case execution time. We present the preliminary design...
The use of Graphics processing unit (GPU) and cloud computing has increased at a higher rate. GPU provides high speed computational power for various applications and accelerates there executional speed by the parallel processing units. Maximum utilization of GPU is enabled by CUDA which is one of the parallel processing model. The power of GPU is effectively utilized by it. Cloud computing on the...
The integration of Cloud Computing with information systems architectures continues to grow at a rapid pace due to the availability of high quality, low cost computing services and organizational efforts to improve efficiency and productivity. Enterprises are increasingly comfortable turning to the Cloud for IT solutions, where teams of dedicated, specialized experts deliver important capabilities...
It is increasingly being recognized that faster socioeconomic development in Africa is dependent upon the development of Information and Communication Technology (ICT) Infrastructure for the dissemination of data and educational services. The scalability and flexibility provided by Cloud services in terms of resource management, service provisioning and virtualization makes it an attractive system...
The problem of reasonable architectural and micro-architectural (at the level of functional blocks organization) synthesis still remains essential and the least formalized for complex embedded systems. Hardware and software components use configuration mechanisms at many system levels, which considerably complicates design. The HLD-methodology (High Level Design) of embedded systems design allows...
Current approaches for enterprise architecture lack analytical instruments for cyclic evaluations of business and system architectures in real business enterprise system environments. This impedes the broad use of enterprise architecture methodologies. Furthermore, the permanent evolution of systems desynchronizes quickly model representation and reality. Therefore we are introducing an approach for...
Integration of hospital information systems (HIS) is an important area and one the basic requirements of hospitals since it increases quality of care and at the same time reduces costs of creating, upgrading, updating and keeping up with technology and healthcare industry standards and information technology. Cloud computing with features like multitenancy, massive scalability, elasticity, pay as...
Knowledge of the global architecture of the cell nucleus and the spatial organization of genome is critical for understanding gene expression and nuclear function. Single-cell imaging techniques provide a wealth of information on the spatial organization of chromosomes. Computational tools for modelling chromosome structure have broad implications in studying the effect of cell nucleus on higher-order...
Context: Agile Governance has been suggested as an innovative approach based on the use of the principles and values of the manifesto for agile software development on traditional Governance. However, the evaluation of this maturity is presented as a challenge today. Objective: This article describes a proposal of a model for the evaluation of maturity according to the meta principles of Agile Governance...
