The performance of primary health care clinic can be impacted by both of patient behavior and appointment rules. In this paper, we compare and evaluate the level of patient service and clinic performance of different overbooking appointment rules under changing patient behavior. The focus is on the appropriate selection of overbooking rules based on panel characteristics. Analysis methodology involves...
In this paper a new method is proposed for classifying randomly deployed sensor nodes over an area of interest into distinctive categories. The problem of event region and event boundary detection in Wireless Sensor Networks (WSNs) is addressed. Particularly, analysis is provided for a scenario whereby an area of interest featuring two distinctive phenomena is being monitored with a randomly deployed...
In computer game software, the implementation of simulated urban crowds is widespread. Representation of pedestrians in computer games has, to date, lagged behind what has been shown possible in academic studies and simulation software. Primary reasons for this are the strict CPU budgets that game AI has to function under, and algorithm implementation which is frequently complex for even a baseline...
Performance and scalability of service-oriented applications, such as Web service compositions or business processes, depend on the dynamically bound services. In order to handle an increasing number of clients, load-balancing techniques are important. In this paper we assume the presence of multiple functionally equivalent services and explore different load-balancing algorithms to dynamically select...
Exact matchings have been extensively studied in the past, but there is relatively little work about approximate matchings. We present a throughput analysis when random arbitration is used to obtain approximate matchings. We compute the throughput by the average available credits at outputs, which is obtained through a DTMC modeling. We also devise an iterative solving procedure for the DTMC of available...
This paper proposes a new pulse-frequency-modulation (PFM) digital pixel sensor (DPS) with an in-pixel variable reference voltage generator to increase the resolution of the pixel, especially when the level of illumination is low. The proposed PFM DPS offers the attractive characteristics of a reduced integration time when the level of illumination is low, reduced complexity of routing and silicon...
In this study, we designed a Cell-to-ECG forward model to simulate ischemia condition from cell level, and then defined five different ischemia locations including inferior, anterior, septal, lateral, and apex on an actual 3-D heart geometry from CT images. For simulating the early ischemia, the ion channels are adjusted through concentration and conductance. The extent of ischemia is defined with...
