Decision Support System (DSS) are interactive software systems that are built to assist the management of an organization in the decision making process when faced with nonroutine problems in a specific application domain. Non-functional requirements (NFRs) for a DSS deal with the desirable qualities and restrictions that the DSS functionalities must satisfy. Unlike the functional requirements,...

This paper presents de use of the Spin model checker as the core engine to build Decision Support Systems (DSSs) to control complex river basins during flood situations. Current DSSs in this domain are mostly based on simulators to predict the rainfall and the water flow along the river basin. In this paper, we propose a scheme that integrates simulators in the water domain with additional logi...

Recently, we proposed space-time block coded-joint transmit/receive antenna diversity (STBC-JTRD) for narrow band transmission in a frequency-nonselective fading channel; it allows an arbitrary number of transmit antennas while limiting the number of receive antennas to 4. In this paper, we extend STBC-JTRD to the case of frequency-selective fading channels and propose frequency-domain STBC-JTR...

Several existing direct-sequence spread spectrum (DSSS) detection and estimation algorithms assume prior knowledge of the symbol period or sequence length, although very few sequence-length estimation techniques are available in the literature. This paper presents two techniques to estimate the sequence length of a baseband DSSS signal affected by additive white Gaussian noise (AWGN). The first...

Decision Support Systems (DSS) have been used as a managerial decision supporting information system since the mid-1960s and the evolution of DSSs remains important for academia and industries. A new generation of DSSs technology, Self-Service Business Intelligence (SSBI), gives more powerful for information workers to make better decisions based on facts with less dependency to IT department. ...

Agriculture decision support systems (DSSs) play an important role in facilitating evidence-based agricultural decision-making for improving agribusiness productivity. Evaluating and selecting the most appropriate agriculture DSS sustainable is, however, challenging due to existence of production marketing alternatives, a variety objective functions from economic lifestyle long-term sustainabil...

In this paper, we consider the update bandwidth in distributed storage systems (DSSs). The bandwidth, which measures transmission efficiency of process DSSs, is defined as average amount data symbols transferred network when stored a node are updated. This paper contains following contributions. First, establish closed-form expression minimum attainable by irregular array codes. Second, after d...

Wheat is one of the most economically important field crops worldwide. Foliar diseases are a major threat to wheat productivity and primarily managed by implementing less susceptible cultivars using fungicides. With “Farm Fork” strategy under consideration European Union reduce pesticide usage 50% 2030, this elucidates importance utilizing decision support systems (DSS) optimize fungicide appli...

Most dynamic spectrum access research centers on determining the set of frequencies being used by spectrum license holders, taking its converse, and from what remains selecting the optimal subset of spectrum. This, however, assumes unlicensed transmissions have a square power spectrum By shaping our unlicensed power spectra, we can do much more. This paper investigates applications of spectrum ...

The aim of the present study has been to critically review 22 disease scoring systems (DSSs) on oral lichen planus (OLP) that have been reported in the literature during the past decades. Although the presently available DSSs may all have some merit, particularly for research purposes, the diversity of both the objective and subjective parameters used in these systems and the lack of acceptance...
