—This paper proposes a fuzzy set-based approach for handling relative orders of magnitude stated in terms of closeness and negligibility relations. At the semantic level, these relations are represented by means of fuzzy relations controlled by tolerance parameters. A set of sound inference rules, involving the tolerance parameters, is provided, in full accordance with the combination/projectio...

In the last years have seen a strong increase in the 802.11 wireless local area network (WLAN) technologies use, and the security mechanisms implemented by amendments IEEE 802.11i and IEEE 802.11w have proven not very effective in combating attacks against availability of WLAN services. Intrusion detection systems emerge as a way to help computer networks in this combat against the deny of serv...

A new type of replenishment policy is suggested in an entropy order quantity model for a perishable product possessing fuzzy holding cost and fuzzy disposal cost. This model represents an appropriate combination of two component demand with discounted selling price, particularly over a finite time horizon. Its main aim lies in the need for an entropic cost of the cycle time is a key feature of ...

The need for data mining applications in describing, explaining and forecasting spatial patterns has been on a steady increase owing to the huge rise in the number of civilian satellite repositories and the efficient utilization of remotely sensed earth observation data for the study of earth system. Fire is one of the major causes of surface change and happens in the mass of vegetation zones a...

The drastic ascent in the volume of spatial data owes its growth to the technical advancements in technologies that aid in spatial data acquisition, mass storage and network interconnection. Thus the necessity for automated detection of spatial knowledge from voluminous spatial data arises. Fire plays a vital role in a majority of the forest ecosystems. Forest fires are serious ecological threa...

A properly designed handoff algorithm is essential in reducing the connection quality deterioration when a mobile node moves across the cell boundaries. Therefore, to improve communication quality, we identified three goals in our paper. The first goal is to minimize unnecessary handovers and increase communication quality by reducing misrepresentations of RSSI readings due to multipath and sha...

Handling Editor: Stephanie Castro In this study, we develop and examine a model of leaders' impression management during organizational decline by elaborating on the roles of publicity, image concerns, and incentive compensation. We propose that the publicity of decline is an important antecedent of leaders' impression management during decline. We also examine how leaders' image concerns media...
