Wide-area control helps in suppression of interarea oscillations in electric power systems, but potentially requires a substantial investment into the communication network needed to exchange state information. To provide companies with incentives to subsidize the wide-area communication links, a fair cost-allocation method based on the theory of cooperative network-formation games (NFG) is developed...
Cloud computing provides software, platform, and infrastructure as a service that helps organizations to perform several resource intensive tasks. The services offered by a cloud service provider are limited by provider-specific options in terms of the pre-specified configurations. Moreover, it is sometimes expensive to pay a fixed amount of money without any format of negotiation or price-matching...
A great challenge faced by many organizations refers to translating their large computing infrastructure into an effective tool to support their productive chain. In this paper, we introduce a modular single point of access middleware approach focused on integrating distributed and heterogeneous computing resources, coined as Dédalo. Since its design, which follows a software product line (SPL) paradigm,...
The spreadsheet is one of the most popular information systems ever: It is exceedingly widely adopted, it has attracted significant amounts of investment and innovation by companies, and it has become a platform for new research. To uncover reasons for the spreadsheet's success, this paper applies a research method, the case study, to analyze the historical development and adoption of this important...
In the management of distributed software development, project managers face many challenges. Some of the most critical ones are related to the allocation of tasks between remote teams. To assign a task to a site or team, the project manager should take into account several factors such as team's technical expertise and cultural similarities. He or she usually makes this decision in a subjective way...
Efficient heterogeneous resource management is one of the many challenges Cloud systems exhibit, because it can lead to increasing the profit obtained by Cloud providers by serving more client requests while fulfilling their requirements with the minimum set of resources. In this context, heterogeneous architectures composed by accelerators, and Field Programmable Gate Arrays (FPGAs) in particular,...
Efficient coordination among network elements and optimal resource utilization in heterogeneous mobile networks (HMNs) is a key factor for the success of future 5G systems. The COHERENT project focuses on developing an innovative programmable control and coordination framework which is aware of the underlying network topology, radio environment and traffic conditions, and can efficiently coordinate...
P2P outsourcing model is introduced to describe an interaction process of project tasks distribution between employees as a part of the enterprise project management system that supports decision-making process within the company. The proposed solution provides an agile technology of tasks allocation in enterprises with matrix organizational structure. The described approach was implemented using...
The cloud service model is spreading into the telecommunications industry, forcing the telecommunications providers to adjust their production models. The network service provider cloud platform, also called as Telco Cloud, utilizing a cloud based production model, is a solution to respond to the changing market forces. The cloud based production model is a new concept in the context of telecommunication...
Companies listed on the stock markets are typically obliged to publicly disclose any information that might have a significant influence on their stock prices. This transparency regulation is intended to ensure that all market participants have access to the same information. The corresponding press releases are one of the most reliable news sources concerning a company's operations. Interestingly,...
Based on the requirements of traditional video conference systems and the structure of MCU resource pool, a unified distributed resource pool system is proposed to achieve an integrated solution for conference resource deployment and management. The MCU resource pool architecture is designed by combining the cloud computing, virtualization, distributed resource management, and other core technologies...
The article proposes a distributed reinforcement learning collaborative consensus algorithm for dynamic generation command dispatch of AGC in interconnected power grids under the framework of the virtual power generation tribes, in order to in response to the development of the EMS system in the Smart Grid from centralization to decentralized form. The simulation results of the Guangdong Grid show...
Information systems (IS) are frequently modified according to changes in enterprise business and operating models and other internal and external factors that influence the enterprise. The changes are systematically managed following the engineering change management (ECM) process. The main issue in the ECM process is that the IS changes and their impact frequently are not evaluated with respect to...
As technology has evolved, so too has the way which we store information: Simple items like photographs which, in the past we could have flicked through in a printed album, are now often only stored online. If they are not accessible online, they will therefore not be accessible at all once we are no longer around to locate them. This may have a psychological impact on the people we leave behind....
Manufacturing costs and tolerance will affect the price and the quality of a product from every manufacturer company. Companies must produce high-quality products with low manufacturing costs in order to keep their products competitive in the market. However, it is difficult to produce a high-quality product with a low manufacturing cost. Companies have difficulties in determining the components to...
Viral marketing, a marketing strategy that leverages the influence power in intimate relationship, has become more prevalent due to the popularity of online social networking services in recent years. Consumers are more likely to make a purchase based on social media referrals. Since marketing through social media and traditional channels may target on different audiences, how to maximize the revenue...
With technological developments and the appeal for rational use of electricity, new equipment was developed to promote a change in the relationship between consumers and power utility companies. The introduction of smart meters and the development and improvement of new sources of power generation near of energy consumption point, become the customer in an active agent in the electrical grid, where...
Yard Allocation Problem (YAP) is a frequently problem observed in port logistic operations, and consists in a temporary assignment of cargo containers, both export and import, to blocks storage located in the operation zone of seaports. The principal objective of YAP resolution is to improve the operations efficiency both terminal port as shipping companies that use the seaport, which allow to decrease...
Assets in transmission systems are maintained according to the time-based strategy. But assets importance for the availability of the grid is neglected which means the allocation of maintenance expenditures may be inefficient. This paper introduces an optimization model which is able to improve the reliability of a transmission system as well as expenditures for maintenance and replacement. It is...
Key-value caches, represented by Mem cached, play a critical role in data centers. Its efficacy can significantly impact users' perceived service time and back-end systems' workloads. A central issue in the in-memory cache's management is memory allocation, or how the limited space is distributed for storing key-value items of various sizes. When a cache is full, the allocation issue is how to conduct...
