Is Cervicotomy Enough for Removal of Retrosternal Goiters?
(Tubitak Scientific & Technical Research Council Turkey, 2008)
Aim: The aim of this study was to evaluate the surgical approaches in retrosternal goiters. Materials and Methods: We reviewed 23 patients operated with the diagnosis of retrosternal goiter. Twelve (52%) of the cases were ...
Minimizing the maximum lateness in a scheduling problem with a time-dependent learning effect: A non-linear programming model
(Gazi Univ, Fac Engineering Architecture, 2008)
In traditional scheduling problems, most literature assumes that the processing time of a job is fixed. However, there are many situations where the processing time of a job depends on the starting time or the position of ...
Second Order Elastic Constants and some thermoelastic properties of alkali halides using Woodcock potential
(2001)
Second Order Elastic Constants (S.O.E.C) of NaCl-type crystals have been calculated using the Woodcock potential. Short-range repulsive interactions have been included up to second-nearest neighbors. This potential form ...
Modeling of the vibrations caused by ball bearing defects
(2003)
In this study a shaft-ball bearing system is modeled in order to investigate the vibrations of ball bearings with running surfaces defects. Shaft and bearing was modeled as mass-spring system and balls were assumed have ...
Superior mesenteric artery syndrome: CT and ultrasonography findings
(2005)
Purpose: The purpose of the study was to describe-computed tomography (CT) and ultrasonography findings in superior mesenteric artery syndrome (SMAS). Materials and methods: The study was performed on 89 CT examinations. ...
Column of bertin: Normal sonographic findings
(2005)
Introduction: We aimed to describe the normal and pathologic sonographic (US) findings of column of Bertin (CB). Materials and methods: The study was performed on sixty-six patients who had CB on CT. CB was found to be ...
Using angle of arrival (bearing) information for localization in robot networks
(2007)
In this paper, we consider using angle of arrival information (bearing) for localization in robot networks. The essential property we require in this paper is that a node can infer heading information from its neighbors. ...
A correspondence between IBA-I and IBA-II model and electromagnetic transitions of some erbium isotopes
(2007)
Since the lowest levels are symmetric under the interchange of neutrons and protons from calculations in the interacting boson approximation IBA-2 model, IBA-1 model space, in which neutron and proton degrees of freedom ...
Determination of rolling element bearing defects through vibration analysis
(2003)
Determination of rolling element bearing defects through the available vibration analysis method is studied in this paper. Rolling element bearing defect vibrations, vibration measurement and their analysis is briefly ...
A full adaptive observer for DC servo motors
(2003)
An adaptive observer estimating all parameters and load torque is proposed for DC servo motors. The observer uses no direct feedback but the adaptation schemes use current and speed measurements. Both the observer and ...
