در این پژوهش، نخست برآوردگری برای نقطه تغییر پارامتر فرایند دو جمله ای3 که تغییر به صورت روند خطی می باشد، بر پایه تابع درستنمایی و برآورد جدیدی برای پارامتر شیب، ارائه شده است. پس از آن برآوردگر نقطه تغییر پله ای در پارامتر فرایند دو جمله ای بر پایه بهینه سازی تابع درستنمایی به کمک الگوریتم وراثتی ارائه شده است. عملکرد برآوردگرهای پیشنهادی با انجام مطالعات گسترده شبیه سازی مورد ارزیابی قرار گر...
in this paper, first the available single charting methods, which have been proposed to detect simultaneous shifts in a single process mean and variance, are reviewed. then, by designing proper simulation studies these methods are evaluated in terms of in-control and out-ofcontrol average run length criteria (arl). the results of these simulation experiments show that the ewma and ewms methods ...
The extracellular domain of the complement receptor type 1 (CR1; CD35) consists entirely of 30 complement control protein repeats (CCPs). CR1 has two distinct functional sites, site 1 (CCPs 1-3) and two copies of site 2 (CCPs 8-10 and CCPs 15-17). In this report we further define the structural requirements for decay-accelerating activity (DAA) for the classical pathway (CP) C3 and C5 convertas...
Clathrin-mediated endocytosis (CME) is the major pathway for concentrative uptake of receptors and receptor-ligand complexes (cargo). Although constitutively internalized cargos are known to accumulate into maturing clathrin-coated pits (CCPs), whether and how cargo recruitment affects the initiation and maturation of CCPs is not fully understood. Previous studies have addressed these issues by...
Large volumes of fly ash and other coal combustion products (CCPs) are produced every year by coal-fired power plants. About 50% of the CCPs produced in the U.S. is buried in impoundment lagoons or dry landfills. Fly ash is generally enriched in several potentially hazardous trace elements, such as As, B, Cd, Co, Cr, Mo, Se, Sr, and V, which can leach from older, unlined disposal sites. Therefo...
Heuristic Based Extraction of Causal Relations from Annotated Causal Cue Phrases By Matthew J. Hausknecht This work focuses on the detection and extraction of Causal Relations from open domain text starting with annotated Causal Cue Phrases (CCPs). It is argued that the problem of causality extraction should be decomposed into two distinct subtasks. First, it is necessary to identify Causal Cue...
Bar charts are common data representations in scientific and technical papers. In order to recognize the printed bar charst, we present a new Hough based bar chart recognition algorithm which combines syntactic analysis into segmentation. We first detect the most salient feature in any bar chart, bar patterns, using syntactic analysis in the Hough domain. Then we group text primitives according...
Controlling the quality of materials, components, batches, products and assemblies during the course of manufacture is probably the most popularly recognized Quality Control activity. A charting and pattern recognition tool has been developed using Visual Basic and MS-Excel to automate the drawing of control charts. This can also enable better visualization of process data and provide automated...
control chart is the most well-known chart to monitor the number of nonconformities per inspection unit where each sample consists of constant size. generally, the design of a control chart requires determination of sample size, sampling interval, and control limits width. optimally selecting these parameters depends on several process parameters, which have been considered from statistical and...
