Cloud computing is becoming a relatively mature paradigm in the ICT landscape. In light of the growing appetite for resources and service levels on par with user expectations, multi-cloud scenarios are becoming the next frontier in the usage of distributed datacenters for private and hybrid Cloud scenarios. Application deployment in particular is a noteworthy feature to be evaluated as microservices...
With the continuous emergence of all kinds of complex systems and the increasing complexity of complex systems, standards architecture becomes more and more important for its guidance and support in the life cycle of complex systems. First, this paper makes a comparative study on several architectures and architecture frameworks, and the comparative study shows that Standards Viewpoint is a better...
Every company stores more and more product data. Most of the data are not analyzed and possible findings cannot be used. But the utilization of existing knowledge can make the system development process more efficient. Therefore, this paper focuses on the data analysis of system architectures. It develops a concept to identify patterns between system architectures of different products in a database...
Many Geographic Information Systems (GIS) are currently built according to the N-Tier architectural style. Despite the advantages of this style in terms of simplicity for the GIS business domain, it lacks many capabilities related to several key characteristics that might affect reusability and extensibility of GIS systems. Service-oriented architecture (SOA), on the other hand, can better serve the...
Network Functions Visualization is focused on migrating traditional hardware-based network functions to software-based appliances running on standard high volume severs. There are a variety of challenges facing early adopters of Network Function Virtualizations; key among them are resource and service mapping, to support virtual network function orchestration. Service providers need efficient and...
This work presents the design, implementation, and evaluation of a learning platform that addresses two main objectives: first it provides and on-line quiz tool for students which can be used as a complementary learning approach to the classroom courses. Secondly, this tool performs a detailed analysis of learners use, considering not only the number of mistakes students have made but also the student...
This paper presents an FPGA-based algorithm for automatic detection of QRS complexes in ECG signals. The proposed algorithm is divided into 3 blocks: Filtering, Contrast Enhancement, and finally a Detection block based on time and amplitude thresholding of the enhanced data. The entire detection scheme was developed in accordance with embedding constraints. For validation, the method was tested on...
In recent years, many Communication Service Providers (CSP) plan to gradually move from telecommunication companies to cloud service providers and many third party software vendors are invited as partners of CSPs. Without an agile cloud service enabling architecture, CSPs cannot integrate their own services with partners' efficiently due to some issues. First, silo operation support system (OSS) is...
The organization of service-oriented knowledge extraction analytical platform infrastructure based on DBMS PostgreSQL is considered. The architecture of analytical platform infrastructure that satisfies requirements of SQL/MM and PMML standards is proposed. The analytical platform infrastructure contains the services and resources storages which are called repository. The logical data model of analytical...
In recent years, the research on the resources sharing has made great progress in education area. But it is far from reaching the needs of teachers and students because of the great investment, poor management and service, low intelligence and poor scalability of present Basic Education Resources Sharing Model. With full use of the advantages of cloud computing, such as super computing ability, high...
This article discusses two strategies for managing sensing resources in the cloud and providing them as a service. The first strategy follows the data-centric model, where the cloud offers environmental data to its clients as a service, without any knowledge of how data are measured and processed. The second strategy adopts the device-centric model, which enables the cloud clients to use a virtual...
This paper introduces the Sensor Web architecture of the NeXOS project as example how interoperable standards help, to facilitate the creation of an infrastructure for sharing oceanographic observation data and the integration of sensor data into applications. Important technological foundations of the NeXOS Sensor Web architecture are the concepts of spatial data infrastructures and the Sensor Web...
Cloud computing is continuously growing as a prominent technology for enterprises. While several giant public cloud providers, such as Amazon, Microsoft, IBM, Google are competing to extend their market, there is still a large number of organizations asking higher level of privacy and control over cloud solutions. Therefore, the need to have private cloud solutions is obvious. To overcome this need...
Todays, there is an industry demand in telecommunication networks to provide a full-featured, commercially available, scalable and non-proprietary network management solution, where multi-vendor, multi-technology management systems interoperate in an open architecture environment. This paper presents a novel architecture to enable system interaction in management layer, NML-EML, based on MTNM solution...
The digitization and integration of biodiversity data are essential for supporting environmental conservation and sustainable use of natural resources. Nowadays an increasing amount of data are made available by regional, national and global initiatives, but the efficient use of data still a challenge. New techniques are needed to enable efficient manage and the use of these various types of biotic...
NoSQL databases are growing in popularity for Big Data applications in web analytics and supporting large web sites due to their high availability and scalability. Since each NoSQL system has its own API and does not typically support standards such as SQL and JDBC, integrating these systems with other enterprise and reporting software requires extra effort. In this work, we present a generic standards-based...
New generation of future power system control centers need a paradigm shift in their utility IT operations, coordinated use of applications and the architectural designs to meet new challenges. However, literature on comprehensive architectural design and implementation towards this direction is scarce. In this paper, an architecture design and implementation aspects are demonstrated for integrating...
This paper presents a comparison of three developmental experiences of fuzzy DBMS (Database Management Systems). These developments have expanded the functionality of some existing relational DBMS (PostgreSQL, Oracle, Firebird, SQL Server, MySQL and DB2) to handle queries with vague terms. The three approaches presented are based on three different methods of integration known as weak, medium and...
Storage is an important research direction of the data management of the Internet of Things. Massive and heterogeneous data of the Internet of Things brings the storage huge challenges. Based on the analysis of the IoT data characteristics, this paper proposed a storage management solution called IOTMDB based on NoSQL as current storage solutions are not well support storing massive and heterogeneous...
The article takes the educational resource platform design as the target, which adopts the OGSA design architecture system, and analyzes the advantages of OGSA in terms of solving the heterogeneousness of the resources and integration of resources. By means of the web service, the service resources are organized, and finally in the manner of Internet public standards, made public. The OGSA-based educational...
