Bifurcation mechanism of low-frequency oscillations in power systems with long transmission lines
(2011)
Low-frequency oscillations have long been observed in power systems with long transmission lines. However, the underlying mechanism that leads to these oscillations has not been identified clearly so far; that is, the close ...
Bioactivity of Hydroxyapatite Produced from Sea Snail Turritella Terebra
(POLISH ACAD SCIENCES INST PHYSICS, 2019)
In this study, hydroxyapatite was produced via mechanochemical method using the sea snail Turritella terebra as a calcium source at 1200 degrees C followed by sintering. FT-IR, SEM/EDX, BET, XRD, ICP-OES analyses were ...
An efficient variable neighbourhood search heuristic for the influential selection problem
(National Technical University of Athens, 2014)
A online social network consists of individuals or entities which are tied by a certain type of interdependency such as collaboration, friendship or acquaintance. Due to the wide usage of internet, many companies actively ...
Definition of common conventions for education of CFS system design
(2012)
CFS system of which can be used in the field of low rise residentials, are included in industrialised building systems due to installation principles of the system. Widespreading of the usage of an industrialised building ...

(IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT, 2013)
Turkey is a country where people's entrepreneurial characteristics are high; fifty thousand Turks in Germany established their own businesses. If there are still optimism about the Turkish Economy in spite of creeping ...
Bioceramic production from giant purple barnacle (Megabalanus tintinnabulum)
(Trans Tech Publications Ltd, 2015)
In this study the structural and chemical properties of barnacle shell based bioceramic materials (i.e. hydroxyapatite, whitlockite, monetite and other phases) were produced by using mechano-chemical (hot-plate) conversion ...
Linear Modeling of Multiple Sclerosis and Its Subgroubs
(Turkish Neurological Soc., 2015)
Objective: In this study, 120 patients diagnosed with clinical multiple sclerosis (MS) of relapsing remitting type (RRMS), secondary progressive type (SPMS) and primary progressive type (PPMS) were examined, as well as 19 ...
A comparative study on the electrical and dielectric properties of Al/Cd-doped ZnO/p-Si structures
(SPRINGER, 2019)
We have reported on the electrical and dielectric properties of Al/CdxZn1-xO/p-Si structures. The cadmium-doped zinc oxide (CdxZn1-xO) thin films with various Cd dopants (x=0.10, 0.20 and 0.30) were deposited on p-Si wafers ...
Search for baryon and lepton number violation in J/psi -> Lambda(+)(c)e(-) + c.c.
(Amer Physic Soc., 2019-04-12)
Using 1.31 x 10(9) J/psi events collected by the BESIII detector at the Beijing Electron Positron Collider, we search for the process J/psi -> Lambda(+)(c)e(-) + c.c. for the first time. In this process, both baryon and ...
Improving performance of transcritical CO2 systems, using phase change materials (PCM) in a cold storage application
(International Institute of Refrigeration, 2019)
Thermal energy storage is one of the most promising solutions for energy savings and increasing efficiency. To improve the performance of cold storage applications, incorporating phase change materials (PCM) to these ...
