Progress in decision support systems comes in a variety of forms. These include increased understanding of the organizational consequences of machine-mediated decision making, improved knowledge regarding how to implement DSSs (decision support systems), advances in techniques for managing and maintaining DSSs, and improvements in DSS technology that result in enhanced functionality or reductio...

Although the DSS community generally shows interest in distributed computing when building decision support systems, the use of distributed technologies often remains limited to extension services added to traditional, local DSS functionalities. In other words, distributed computing rarely change the intrinsic (and local) behavior of the DSS. In this paper, we propose new distributed decision s...

There is a great need for domain analysis and modelling for decision support systems (DSSs) with an e0ective methodology to assist the development of DSSs. This paper discusses the object-oriented modelling of DSSs for multicriteria decision making (MCDM) in natural resource management. This approach of DSS modelling is integrated into the uniform framework based on object orientation for both ...

Duplex stainless steels (DSSs) with austenitic and ferritic phases have been increasingly used for many industrial applications due to their good mechanical properties and corrosion resistance in acidic, caustic and marine environments. However, DSSs are susceptible to intergranular, pitting and stress corrosion in corrosive environments due to the formation of secondary phases. Such phases are...

Many mission-critical, decision-making situations happen in dynamic, rapidly changing, and often unpredictable distributed environments. Military, governmental, and medical contexts are examples of such situations, which can be characterized by highly decentralized, up-to-date data sets coming from various sources. Unlike other decisionmaking tools, DSSs designed for such situations are challen...

We consider heterogeneous distributed storage systems (DSSs) having flexible reconstruction degree, where each node in the system has nonuniform repair bandwidth and capacity. In particular, a data collector can reconstruct file using some $$k$$ nodes and, for failure, be repaired by set of active nodes. Using min-cut bound, we investigate fundamental trade-off between costs our model DSS. Fur...

The NP-complete Distinguishing Substring Selection problem (DSSS for short) asks, given a set of “good” strings and a set of “bad” strings, for a solution string which is, with respect to Hamming metric, “away” from the good strings and “close” to the bad strings. Studying the parameterized complexity of DSSS, we show that DSSS is W[1]-hard with respect to its natural parameters. This, in parti...

This study aimed at exploring the psychometric characteristics of the Korean Version of the Depression and Somatic Symptoms Scale (DSSS) in a clinical sample, and investigating the impact of somatic symptoms on the severity of depression. Participants were 203 consecutive outpatients with current major depressive disorders (MDD) or lifetime diagnosis of MDD. The DSSS was compared with the Montg...

The properties of duplex stainless steels (DSSs) depend on the ferrite–austenite ratio, content secondary phases and contamination with non-metallic inclusions. To assess quality DSSs, it is necessary to use an integrated approach which includes controlling for volume fraction, morphology distribution all Samples several grades DSSs were obtained using various heat treatments, such as solution ...

Security has long been a challenging problem in wireless networks, mainly due to its broadcast nature of communication. This opens up simple yet effective measures to thwart useful communications between legitimate radios. Spread spectrum technologies, such as direct sequence spread spectrum (DSSS), have been developed as effective countermeasures against, for example, jamming attacks. This pap...
