Participatory sensing is the process in which individuals or communities collect and analyze systematic data using mobile phones and cloud services. To efficiently develop participatory sensing services, some server-side technologies have been proposed. Although they provide a good platform for participatory sensing, they are not optimized for spatial data management and processing. For the pur...

Organizations are increasingly adopting Knowledge Management Systems (KMS) to realize firm and operational level benefits. Many KMS fail to yield desired outcomes due to the lack of understanding of the antecedents of successful KMS. Prior studies have established organizational culture as a key antecedent of successful KM. This study investigates the relationship between KMS effectiveness, in ...

This paper is about the design and implementation of a wiki-based knowledge management system for improving emergency response. Most organizations face difficult challenges in managing knowledge for emergency response, but it is crucial for response effectiveness that such challenges be overcome. Organizational members must share the knowledge needed to plan for emergencies. They also must be a...

Knowledge management is the active transfer of knowledge throughout an organization. Such organizations may be corporations, nonprofit organizations, governments, or international agencies. It involves the capture, refinement, storage, and dissemination of knowledge. Essentially, the goal of knowledge management is to enable the successful transfer of the right knowledge to the right people, in...

Knowledge sharing abilities are fundamental to the success of an organisation to meet the needs and demands of the customers. The main purpose of this paper is to investigate the Knowledge Management Systems that can be used to improve the knowledge sharing culture among local government employees. The study used an inductive research approach which included a thorough literature review, and th...

The Model Driven Architecture (MDA) approach introduces a clear separation of the business logic from the implementation logic that's less stable. It uses the models that are more perennial than codes. It puts the models at the centre of the development of software and of the information systems. The MDA approach consists at, firstly, developing the CIM Model, secondly, obtaining the PIM model ...

RFC 4601 mandates the use of IPsec to ensure authentication of the link-local messages in the Protocol Independent Multicast Sparse Mode (PIM-SM) routing protocol. This document specifies mechanisms to authenticate the PIM-SM link-local messages using the IP security (IPsec) Encapsulating Security Payload (ESP) or (optionally) the Authentication Header (AH). It specifies optional mechanisms to ...

As we enter the second decade of the 21st Century, we find ourselves at a rare historical moment-a time of great opportunity fraught with substantial pitfalls. Numerous potential trajectories of the Internet may unfold before us. While decentralized and participatory platforms have birthed a revived movement for democratized media production, these phenomena depend on the common resource of the...
