Facial expression classification with Haar features, geometric features and Cubic Bézier curves
(Istanbul University, 2013)
Facial expressions are nonverbal communication channels to interact with other people. Computer recognition of human emotions based on facial expression is an interesting and difficult problem. In this study, images were ...
ON THE ASYMPTOTICALLY PERIODIC SOLUTIONS OF A FIFTH ORDER DIFFERENCE EQUATION
(Univ Prishtines, 2019)
In this paper we investigate the stability of solutions of difference equation x(n+1) = x(n-1)x(n-4) - 1. We also study periodic solutions of related difference equation especially asymptotic periodicity.
Alendronate-functionalized poly(amido amine) cryogels of high-toughness for biomedical applications
(Elsevier Sci Ltd, 2020)
Novel bisphosphonic acid-functionalized poly(amido amine) (PAA) macromers were synthesized through aza-Michael addition of sodium alendronate (ALE) and 5-amino-1-pentanol (AP) to N,N'-methylene bisacrylamide at two different ...
Dual Cross-Linked Polymethacrylic Acid Hydrogels with Tunable Mechanical Properties and Shape Memory Behavior
(Wiley-V C H Verlag Gmbh, 2021)
Herein, a series of poly(methacrylic acid) hydrogels are prepared via bulk polymerization of methacrylic acid (MAAc) and grafting of Triton X-100 (TX-100). One-pot and extremely simple chemistry consist of only mixing and ...
Disaster and emergency preparedness in Istanbul museums
(Routledge Journals, Taylor & Francis Ltd, 2021)
Istanbul is a high-risk city in terms of disasters, as well as having museums hosting many cultural heritage artifacts. The purpose of this study is to analyze the preparation level of museums in Istanbul for disaster and ...
Impact of heating season on the soil pollution in Kirklareli province of Turkey
(Springer, 2021)
This study, conducted in Kirklareli city centre, aims to analyse heavy metal pollution in soil due to heating season (HS). For this purpose, 86 soil samples were taken from the identified locations with a depth of 0-10 cm ...
The role of geothermal energy in sustainable development of Turkey
(2012)
Energy can strongly act a key role in socio-economical development of Turkey. Turkey's energy needs are always increasing because Turkey has a rapidly growing economy and population. Although Turkey has numerous renewable ...
The effect of collector parameters on nanofiber yarns produced by electro yarn spinning machine with conical collector
(Taylor & Francis Ltd, 2021)
In this work, electrospun yarns were produced by a nanofiber yarn spinning machine with a conical collector. In the first part, two different polymers (PAN and PVDF-HFP) were used in nanofiber yarn spinning with two different ...
Investigation of tribological behavior of 20NiCrBSi-WC12Co coated brake disc by HVOF method
(Iop Publishing Ltd, 2020)
In braking systems, which consist of dry sliding lining against a pearlitic cast-iron disc, disc wear has a significant impact on the overall wear rate. In this work, dynamometer tests were conducted to find out the friction ...
QUALITATIVE BEHAVIOURS OF A SYSTEM OF NONLINEAR DIFFERENCE EQUATIONS
(Editura Bibliotheca-Bibliotheca Publ House, 2021)
The paper aims to study the dynamics of a system of nonlinear difference equations x(n+1) = x(n-1)y(n) + A, y(n+1) = y(n-1)x(n) + A where is real number. We especially investigate the stability of equilibrium points, ...
