Complete allocation sampling: An efficient and easily implemented adaptive sampling design
( Wiley , 2010 , Article)Adaptive sampling designs are becoming increasingly popular in environmental science, particularly for surveying rare and aggregated populations. An adaptive sample is one in which the survey design is modified, or adapted, ... -
The complete spectrum of pentalogy of Cantrell in one of a set of dizygotic twins: A case report of a rare congenital anomaly.
( Lippincott, Williams & Wilkins , 2021 , Article)Pentalogy of Cantrell (POC) is an extremely rare syndrome with an estimated incidence of 1:65,000 to 200,000 live births. Its complete form includes a midline epigastric abdominal wall defect, defects affecting the lower ... -
Completeness Of Distributive P-Algebras
( Qatar University , 1988 , Article)According to the triple characterization of distributive p-algebras which is given by T. Katrinak, we characterize the completeness of distributive p-algebras. -
Complex Signs and Pseudo-composites
( Qatar University , 2001 , Article)The purpose of the present paper is to try to find an answer to the question: how are complex signs analyzed in English morphology in the context of Axiomatic Functionalist Theory? The paper provides the tools for analyzing ... -
Complex treatment of oily polluted waters by modified melamine foams: from colloidal emulsions to a free oil removal
( Springer Science and Business Media Deutschland GmbH , 2023 , Article)This study deals with the efficient, low-cost, and scalable treatment of oily polluted waters including colloidal emulsions, oil-in-water mixtures, and free oil removal using melamine foams (MFs) modified by ferric chloride ... -
Complex-impedance response of an Ag/TeO2-V2O5/Ag structure
( Elsevier , 2009 , Article)The ac conductivity of glass samples of composition 50 mol% TeO2 and 50 mol% V2O5 has been analyzed. The samples were prepared by the usual melt-quench method. The electrical conductance and capacitance were measured over ... -
The Complexation of Lanthanides by Azo-B-Diketones Stability Constants
( Qatar University , 1982 , Article)The stability constants of the complexes between the trivalent lanthanide series of cations and series of azo-B-diketone ligands are reported. The measurements were conducted at 30°C and zero ionic strength (free KN03), ... -
Complexity and Use in Building Evaluation (CUBE2): The Modular Case of the BCR Corridors at Qatar University
( Qatar University Press , 2021 , Poster)The BCR Corridors at QU are notorious for wayfinding difficulties of end-users in the building complex. These navigation problems appear to arise due to the repetitive similarity of individual parts in its modular design, ... -
Complexity of Deep Convolutional Neural Networks in Mobile Computing
( Hindawi , 2020 , Article)Neural networks employ massive interconnection of simple computing units called neurons to compute the problems that are highly nonlinear and could not be hard coded into a program. These neural networks are computation-intensive, ... -
Compliance checking for usage-constrained credentials in trust negotiation systems
( Springer Berlin Heidelberg , 2012 , Conference Paper)We propose an approach to placing usage-constraints on RT credentials; issuers specify constraints by designing non-deterministic finite automata. We show by examples that this approach can express constraints of practical ... -
