Estimating the size of OO software is the main issue today in project planning and development. Accurate estimation of size may lead to precise prediction of effort during the process of system development. Predictive Object Point POPs are a metric designed specifically for estimating the size of object oriented software. But there is no direct relation between POP and Software size. In this pa...

This paper considers the e ect of stochasticity on the quality of convergence of genetic algorithms (GAs). In many problems, the variance of building-block tness or so-called collateral noise is the major source of variance, and a population-sizing equation is derived to ensure that average signalto-collateral-noise ratios are favorable to the discrimination of the best building blocks required...

OBJECTIVES To assess the safety, effectiveness, and acceptability of providing a reduced number of ShangRing sizes for adult voluntary medical male circumcision (VMMC) within routine service delivery in Lusaka, Zambia. METHODS We conducted a randomized controlled trial and enrolled 500 HIV-negative men aged 18-49 years at 3 clinics. Participants were randomized to 1 of 2 study arms (Standard ...

BACKGROUND Multidetector computed tomography is useful for determining the appropriate transcatheter heart valve (THV) size in patients with severe aortic stenosis who are suboptimal surgical candidates. The relationship between adherence to the recommended CoreValve sizing algorithm and clinical outcomes is not known. METHODS AND RESULTS We evaluated 1023 patients with severe aortic stenosis...

This paper studies interconnect sizing and spacing (ISS) problem with consideration of coupling capacitance for performance optimization of single or multiple critical nets. We introduce the formulation of symmetric and asymmetric wire sizing. We develop efficient bound computation algorithms for ISS optimization and prove their optimality under general interconnect resistance and capacitance m...

All too frequently, a software cost estimate is required in the early stages of the life-cycle when requirements and design specifications are immature. To produce a cost estimate under these conditions requires extensive use of expert judgment and addressing significant estimation uncertainty. Research has shown that expert judgment under the right conditions can yield relatively "accurate" es...

This chapter presents a review of adaptive population sizing schemes used in genetic algorithms. We start by briefly revisiting theoretical models which rely on a facetwise design decomposition, and then move on to various self-adjusting population sizing schemes that have been proposed in the literature. For each method, the major advantages and disadvantages are discussed. The chapter ends wi...

BACKGROUND There are no international rules regarding which medical supplies to bring when the nurseon- duty is called to emergencies outside a cruise ship's infirmary. Ideally, one First Response Bag should contain all that is needed to manage the initial 10-15 minutes of any medical emergency until the patient can be safely transported to the ship's infirmary. Royal Caribbean Cruises Ltd rece...

We consider the allocation of capacity in a system in which rental equipment is accessed by two classes of customers. We formulate the problem as a continuous-time analogue of the one-shot allocation problems found in the more traditional literature on revenue management, and we analyze a queueing control model that approximates its dynamics. Our investigation yields three sets of results. Firs...

Purpose Energy groups are cargo owners with large amounts of energy sources (such as coal) to transport. To achieve a satisfactory tradeoff between the reliability requirements sea transportation process and need control investment cost, they usually set up self-owned fleet supplemented by chartered fleet. This paper aims investigate best structure evaluate scheme under volatile circumstances i...
