Using Students' Performance to Improve Ontologies for Intelligent E-Learning System
(EDAM, KISIKLI MH ALEMDAG CD YAN YOL SK, SBK IS MERKEZI NO 5, KAT 1 USKUDAR, ISTANBUL, 81190, TURKEY, 2015)
Ontologies have often been recommended for E-learning systems, but few efforts have successfully incorporated student data to represent knowledge conceptualizations. Defining key concepts and their relations between each ...
A robust estimator-based optimal algebraic approach to steam generator feedwater control system
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, ATATURK BULVARI NO 221, KAVAKLIDERE, ANKARA, 00000, TURKEY Categories / Classification, 2016)
Feedwater control systems are used to maintain the steam generator water level within prescribed narrow limits and to provide constant supply of steam during power demand variations. Current feedwater control systems are ...
A new tool for QT interval analysis during sleep in healthy and obstructive sleep apnea subjects: a study on women
(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, ATATURK BULVARI NO 221, KAVAKLIDERE, ANKARA, 00000, TURKEY, 2013)
By monitoring the Q wave/T wave (QT) interval computed from electrocardiography (ECG) signals during sleep, it is possible to create a link between the ventricular repolarization and sleep stages. In this study, we aimed ...
A conceptual process model for the sustainability of a healthy building
(Istanbul Teknik Universitesi, Faculty of Architecture, 2016)
Healthy buildings may lose their healthy characteristics over time and due to changing circumstances during their usage phase, which may lead to biological and psychological health problems for their users. Thus a process ...
DETERMINATION OF 1/V-T (P, CONSTANT) DIAGRAMS OF HYDROGEN GASES BY GRAPH-ANALYTICAL METHODS
(YILDIZ TECHNICAL UNIV, YILDIZ CAMPUS, BESIKTAS, ISTANBUL, 34349, TURKEY, 2017)
Graph-analytical methods provide more accurate results in the analysis of V-T (P=constant) and 1/V-T (P=constant) diagrams of gases. In this study, as a continuation of [1, 2]*, the behavior of hydrogen gas was examined ...
Strain rate and hydrogen effects on crack growth from a notch in a Fe-high-Mn steel containing 1.1 wt% solute carbon
(Elsevier Ltd, 2020)
Effects of strain rate and hydrogen on crack propagation from a notch were investigated using a Fe-33Mn-1.1C steel by tension tests conducted at a cross head displacement speeds of 10-2 and 10-4 mm/s. Decreasing cross head ...
On the existence of positive solutions for the second-order boundary value problem
(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2015)
This paper is concerned with the existence of positive solutions to a second order boundary value problem. By imposing growth conditions on f and using a generalization of the Leggett-Williams fixed point theorem, we prove ...
A simulation-based approximate dynamic programming approach to dynamic and stochastic resource-constrained multi-project scheduling problem
(ELSEVIER, 2024)
We consider the dynamic and stochastic resource-constrained multi-project scheduling problem which allows
for the random arrival of projects and stochastic task durations. Completing projects generates rewards, which
are ...
Predicting the effects of direct-injected fuels co-powered by high-CO2 biogas on RCCI engine emissions using kinetic mechanisms and multi-objective optimization
(ELSEVIER, 2024)
High inert gas content in biogas resulted in poor burning and emissions attributes, though scarcely investigated
in reactivity controlled compression ignition (RCCI). Established kinetic mechanisms were combined with ...
Effects of silver nanowires and their surface modification on electromagnetic interference, transport and mechanical properties of an aerospace grade epoxy
(SAGE Publications Ltd, 2024)
The aerospace industry has progressively grown its use of composites. Electrically conductive nanocomposites are among
important modern materials for this sector. We report on a bulk composite containing silver nanowires ...
