The estimation of project completion time is to be repeated several times in the project planning phase to reach the optimal tradeoff between time, cost, and quality. Estimation procedures provide either an interval or a point estimate. The computational load of several estimation procedures is reviewed. A multiple polynomial regression model is provided for major interval estimation procedures...

This note discusses some problems possibly arising when approximating via MonteCarlo simulations the distributions of goodness-of-fit test statistics based on the empirical distribution function. We argue that failing to re-estimate unknown parameters on each simulated Monte-Carlo sample – and thus avoiding to employ this information to build the test statistic – may lead to wrong, overly-conse...

Bctusbdu ̋In this paper we want to minimize passengers waiting times at the bus stops by making buses wait at a stop. We compare a simple rule based approach to a MonteCarlo method for this problem. When allocated enough time, the Monte-Carlo method gives better results. If the passengers arrivals and the bus travel times are known, the best algorithm is nested Monte-Carlo search with memorizati...

هدف: هدف پژوهش حاضر تعیین نقش واسطه‌­ای اجتناب تجربی و دشواری‌­های تنظیم هیجان در رابطه بین سازوکارهای دفاعی با افکار خودکشی نوجوانان بود. روش: از نوع توصیفی- همبستگی جامعه آماری این شامل تمام شهر کرج پاییز سال 1398 بود که میان آن­ها به روش نمونه گیری دسترس مناطق آموزشی 3 7، 270 نوجوان 15 تا 18 (125 پسر 143 دختر) انتخاب شدند. ابزار پرسشنامه دفاعی-40 آندروز همکاران (۱۹93) (DSQ-40)؛ دشواری گراتز ...

This paper develops a new mathematical-statistical approach to analyze class of Flajolet-Martin algorithms (FMa), and provides analytical confidence intervals for the number F0 distinct elements in stream, based on Chernoff bounds. The FMa has reached significant popularity bigdata stream learning, attention literature mainly been algorithmic aspects, basically complexity optimality, while stat...

We propose a realistic 3D positioning system for indoor navigation that exploits visible Light Emitting Diodes (LEDs), placed on the ceiling. A unique frequency tone is assigned to each lamp and modulates its intensity in periodic time slots. The Time Difference of Arrival (TDOA) measured without need synchronization between sources receiver, then it used accurately estimate receiver position. ...

PS PLUS software offers power providers the ability to implement intelligent gas turbine life cycle management processes. Operators wish to achieve higher availability by reducing unnecessary scheduled outages for either inspection or repair. PS-PLUS is a SPAR-based application that uses the MonteCarlo (MC) method to estimate machinery remaining useful life. The method predicts the scope and sc...
