This research intends to analyze the optimal operation pattern for fulfilling raw water demand, and it is conducted in integrated cascade reservoir of Duriangkang-Muka Kuning, Batam City, Indonesia. However, City economic center Riau Islands absolutely needs enough supplies support its development. The need predicted reach about 6,630.29 l/s 2025. Due population growth that estimated 1.8 millio...

Our main result is that two point interpolatory subdivision schemes using C nonlinear averaging rules on pairs of real numbers generate real-valued functions that are also C. The significance of this result is the following consequence: Suppose that S is a subdivision algorithm operating on sequences of real numbers using linear binary averaging that generates C real-valued functions and S is t...

Receiver operating characteristic (ROC) curves are very popular for evaluating a diagnostic test or score performances in various decision making applications: medicine, marketing, credit scoring etc. The ROC curve provides a concise graphical representation of the trade off between sensitivity and specificity. We will focus here on supervised classification into two groups. Error rate estimati...

OBJECTIVES The importance of the prediction of coronary heart disease (CHD) has been recognized in Korea; however, few studies have been conducted in this area. Therefore, it is necessary to develop a method for the prediction and classification of CHD in Koreans. METHODS A model for CHD prediction must be designed according to rule-based guidelines. In this study, a fuzzy logic and decision ...

OBJECTIVE The present study aimed to establish whether a more optimal cutoff value for D-dimer testing could definitively rule out acute deep vein thrombosis (DVT). METHODS Between April 2009 and March 2010, 190 referral patients suspected to have DVT were assessed by the D-dimer assay. Additionally, ultrasonography (US) and computed tomography (CT) imaging were performed to detect thrombosis...

We examine the relation between cost and quality in networks which carry aggregate traffic. A powerful tool in this is the burstiness or indifference curve associated with a stochastic traffic flow. We relate burstiness to quality and use this relation to explore the quality experienced by aggregated flows under various rules for allocating resources to them. An example is motivated by the Cont...

Intelligent control of public lighting is nowadays one the most challenging issues in smart city deployment. Lighting optimization entails a compromise between comfort, safety, and power consumption, affecting both vehicles pedestrians. Smart solutions must estimate their characteristics to trade-off users’ needs energy requirements. This paper proposes an intelligent street system Receiver Ope...

This paper proposes the allocation of operating reserve in power systems through competitive capacity markets using a probabilistic approach. The insurance features of operating reserve are used to derive a valuation model that is analytically consistent and reflects the economic value of increased reliability to customers. The model can be expressed in the form of a demand curve for operating ...
