Chlormequat chloride (CCC) as one of the most important growth retardants has been used for manipulation of growth and yield of cereal crops; however, the effect of CCC has not yet been well understood under drought stress conditions. Therefore, one greenhouse and a field experiment were conducted to examine the effects of CCC on yield and yield components of wheat in drought conditions at Coll...
در بسیاری از موارد، اندازه گیری واقعی واحدها با مشکلات فراوانی از قبیل صرف وقت و هزینه، به بار آمدن اثرات مخرب و کار طاقت فرسا همراه است، در حالی که رتبه بندی واحدها آسان و کم هزینه تر است. در این گونه موارد روش نمونه گیری مجموعه رتبه دار جایگزین مناسبی به جای روش نمونه گیری تصادفی ساده به نظر می رسد. در این پایان نامه ابتدا مرور مختصری بر کنترل کیفیت آماری صورت گرفته و سپس روش نمونه گیری مجموع...
Abstract The objective of this meta-analysis was to explore variability in milk production associated with rumen fermentation parameters and diet characteristics. Data were extracted from 138 journal articles used derive 6 models predict MY. Each model considered a different set independent variables, including (R), (D) their combination (R+D), or without interactions pH. Rumen included total v...
The calculation of the main circuit parameters is basic part engineering design for high voltage direct current (HVDC) transmission systems. Compared to conventional line commutated converter (LCC), application capacitor (CCC) can reduce probability commutation failures and shunt reactive compensation. This paper proposes a method CCC-based HVDC system. Firstly, topology CCC-HVDC system describ...
BACKGROUND In Alberta (Canadian province), the Chat Check Chart (CCC) model was developed to help pharmacists understand how patient care standards fit into routine practice. The CCC model outlines a process that covers the following: 1) Chart-asking three prime questions to gather information; 2) Check-perform pharmacotherapy workup by assessing prescription's indication, efficacy, safety and ...
The overall goal of our research is the automatic recognition of the intended message of a grouped bar chart. This paper presents our preliminary work on a system that utilizes the communicative signals in a grouped bar chart as evidence in a Bayesian network that hypothesizes the primary message conveyed by the graphic. The paper discusses the kinds of communicative signals present in grouped ...
Let HC ′ denote the set of sets of hereditary cardinality less than 2ω. We consider reflection principles for HC ′ in analogy with the Levy reflection principle for HC. Let B be a class of complete Boolean algebras. The principle Max(B) says: If R(x1, . . . , xn) is a property which is provably persistent in extensions by elements of B, then R(a1, . . . , an) holds whenever a1, . . . , an ∈ HC ...
Multivariate control charts such as Hotelling`s T^ 2 and X^ 2 are commonly used for monitoring several related quality characteristics. These control charts use correlation structure that exists between quality characteristics in an attempt to improve monitoring. The purpose of this article is to discuss some issues related to the G chart proposed by Levinson et al. [9] for detecting shifts in ...
In many quality control applications, the necessary distributional assumptions to correctly apply the traditional parametric control charts are either not met or there is simply not enough information or evidence to verify the assumptions. It is well known that performance of many parametric control charts can be seriously degraded in situations like this. Thus, control charts that do not requi...
