A note on indices of primepower and semiprime divisor function graph
(Işık University Press, 2021)
The notion of using number theortic based graph seems to be one of the flourishing areas in Graph theory. One such concept is the divisor function graph GD(n) which is defined as: For any positive integer n ≥ 1 with r ...
Distance spectra of some graph operations and some new distance equienergetic graphs of diameter 3
(Işık University Press, 2019)
Two graphs of same order are said to be distance equienergetic if their distance energies are same. In this paper, we first give a partial insight on the distance spectrum of Mycielskian graphs and then we focus on ...
On the spectra of cycles and paths
(Işık University Press, 2019)
Energy of a graph was defined by E. Hückel as the sum of absolute values of the eigenvalues of the adjacency matrix during the search for a method to obtain approximate solutions of Schr¨odinger equation which include the ...
Edge-Zagreb indices of graphs
(Işık University Press, 2020)
The algebraic study of graph matrices is an important area of Graph Theory giving information about the chemical and physical properties of the corresponding molecular structure. In this paper, we deal with the edge-Zagreb ...
Intermittent resources assessment on power grid under an hourly scaled bottom-up model
(Işık Üniversitesi, 2022-07-04)
This study aims to model and examine the Turkish electricity sector by using TIMES modeling framework. It attempts to investigate the decisions of the proposed model under various scenarios. As the energy need grows globally, ...
Turkish electricity sector: a bottom-up approach
(Işık Üniversitesi, 2017-01-17)
The importance of this study, roots from being the first attempt to model and examine Turkish energy system specific to electricity sector using TIMES modelling methodology to assess the future pathways of the system under ...
Yapıda sık kullanılan malzemelerin ekolojik olarak değerlendirilmesi
(Işık Üniversitesi, 2018-08-28)
İnşaat sektörü yaşanan nüfus artışı, endüstrinin gelişimi ve kentleşmenin artmasından dolayı tüm dünyada gelişmektedir. Bununla birlikte, yapı malzemelerinin üretimleri sırasında harcanan enerji miktarı, açığa çıkan karbon ...
P-T phase diagram for NH₄F
(Editions Scientifiques Medicales Elsevier, 2002-04)
In this study we obtain a P-T phase diagram of NH4F using the mean-field theory. We fit our calculated phase line equations to the experimental P-T phase diagram. By choosing appropriately the coefficients in the free-energy ...
Yeşil çatı sistemlerinin su ve enerji dengesi açısından değerlendirilmesi
(Istanbul Univ, Fac Forestry, 2016)
Yeşil çatı kavramı, günümüzde sığ derinliğe sahip bir yetişme ortamı üzerinde (2-10 cm), değişken çevre koşullarına uyum sağlayabilen otsu bitki türleriyle bitkilendirilen, bakım ihtiyaçları düşük olan, üzerinde bulunduğu ...
An essential approach to the architecture of diatomic molecules: 1.Basic theory
(Optical Soc Amer, 2004-11)
We consider the quantum-mechanical description of a diatomic molecule of electronic mass m(0e), internuclear distance R-0, and total electronic energy E-0e. We apply to it the Born-Oppenheimer approximation, together with ...
