Abstract Aiming at how to solve the problem of optimal matching between imaging reconnaissance user requirements and satellite resources, this paper conducts research on preprocessing requirements. First, considering remote sensor type resolution satellites, a requirement-resource matrix is constructed realize preliminary resources. Secondly, starting from time constraints, by calculating obser...

The principal features of the ALICE Central Trigger Processor are presented, as described in the draft User Requirement Document currently under discussion.

This paper addresses the issue of achieving energy efficiency in heterogeneous cellular networks (HetNets). The use of sleep control strategy and distance based energy requirement enables us to achieve optimized energy efficiency. The proposed system connects to the problem of heterogeneity and finds solution to the balance in terms of communication distance based energy requirement, the networ...

The paper presents a proposal of a method for MDA based “on-the-fly” modelling of Musical Real Time Applications. The method is based on use of the Executable and Translatable UML approach (xtUML) with regards to implementation on embedded systems. Since the goal is to implement a real-time application requiring certain real-time Quality of Service (QoS) properties, the real-time response requi...

The design of decisional data base schema in general is done by an administrator. According to data-driven, requirement-driven or hybrid paradigms, he determine facts and dimensions. This process which based on data source or end-user requirement are often complex and approximate. We propose to elaborate decisional data-base schema by the end user following hybrid approach. Through assistance a...

nowadays, standardized metadata for geospatial data is a key in sharing and finding information on the web and crucial in building geospatial data infrastructure (gdi). the main objective of this paper was to develop a web-based metadata dissemination system for in-situ sensors based on, most importantly, interoperable, standard and open technologies introduced by open gis consortium (ogc), nam...

We have witnessed a significant increase of the user requirements in the field of multimedia services. Therefore, service providers are forced to assure specific level of quality to earn the trust of theirs customers. QoE together with video quality have become essential terms in regard of designing any video-providing services. However, it was proved that current methods in the user-centered s...

CLARIN-DK is a platform with language resources constituting the Danish part of the European infrastructure CLARIN ERIC. Unlike some other language based infrastructures CLARIN-DK is not solely a repository for upload and storage of data, but also a platform of web services permitting the user to process data in various ways. This involves considerable complications in relation to workflow requ...

A user’s data is represented by a finite-valued random variable. Given a function of the data, a querier is required to recover, with at least a prescribed probability, the value of the function based on a query response provided by the user. The user devises the query response, subject to the recoverability requirement, so as to maximize privacy of the data from the querier. Privacy is measure...
