Oceans, seas, and marine resources are highly relevant for achieving the Sustainable Development Goals. Such relevance has given rise to blue economy approach, where scholars policymakers see activities carried out in cargo ports from a different perspective. The approach stresses emergence of multiple transnational networks relation these topics development green plus environmental measurement...

Hospital length of stay is an important performance indicator for hospital management and a key measure of efficiency in health care. However, it is difficult to analyze as most distributions pertaining to hospital length of stay are asymmetric due to outliers. The objective of the present study is to suggest a new method to estimate average length of stay (ALOS). Data on LOS in the year 2010 f...

Resource allocation problems are concerned with the allocation of limited resources among competing agents so as to achieve the best system performances. In systems which serve many users, like in networking, there is a need to respect some fairness rules while looking for the overall efficiency. The so-called Max-Min Fairness is widely used to meet these goals. However, allocating the resource...

This paper presents the performance evaluation of an authorship verification technique that is based on a modified version of General Impostors (GI) [2]. The novelties of this implementation are: 1. a modified way of combining the min-max similarity measure and, 2. a relatively large set of diverse features that spans letter-level, word-level, function word-level, word shape-level, and word tag...

The emergence of video has presented new challenges to the problem of face recognition. Most of the existing methods are focused towards the use of either representative exemplars or image sets to summarize videos. There is little work as to how they can be combined effectively to harness their individual strengths. In this paper, we investigate a new dual-feature approach to face recognition i...

The innovative techniques of TCP Vegas have been the subject of much debate in recent years. Several studies have reported that TCP Vegas provides better performance than TCP Reno. However, the question which of the new techniques are responsible for the impressive performance gains remains unanswered so far. This paper presents a detailed performance evaluation of TCP Vegas. By decomposing TCP...

International cross-border private hospital chains need to apply the standards for foreign currency translation in order to consolidate the balance sheet and income statements. This not only exposes such chains to exchange rate fluctuations in different ways, but also creates added requirements for enterprise-level IT systems especially when they produce parameters which are used to measure the...

In this paper, we propose a delay-tolerant secure long-term health care scheme, RCare, for collecting patient’s sensitive personal health information (PHI). Specifically, to minimize the overall health care cost, RCare provides network connectivity to rural areas using conventional transportation vehicles (e.g., cars, buses) as relay nodes. These vehicles are expected to store, carry, and forwa...

Linear Increase/Multiplicative Decrease (LIMD) has typically been the congestion control paradigm of choice in the Internet. However, a major drawback of LIMD is that it reacts identically (and aggressively) to all packet losses, irrespective of the cause of loss. In this paper, we try to augment the basic LIMD congestion control with additional mechanisms to predict the cause of packet losses ...

An increasing number of information systems support their users by helping them in reusing existing knowledge and experience. Often this is done by retrieving similar instances like similar documents, similar process executions or similar persons. While the recommendations use similarity as central concept, the selection of a suitable measure is often done by intuition. This paper introduces a ...
