Glasses and glass-ceramics in the SrO-TiO2-Al2O 3-SiO2-B2O3 system and the effect of P2O5 additions
(Journal of Materials Science, 2008)
The glass formation abilities of various compositions in SrO-TiO 2-Al2O3-SiO2, SrO-TiO 2-B2O3-SiO2, SrO-TiO 2-Al2O3-B2O3, and SrO-TiO2-Al2O3-SiO2-B 2O3 systems were studied. Many new compositions were found to be suitable ...
A new electronically tunable phase shifter employing current-controlled current conveyors
(AEU - International Journal of Electronics and Communications, 2008)
A new canonical current-mode (CM) filter topology is presented. It realizes first-order allpass filtering functions using two dual-output current-controlled current conveyors (DO-CCCII) and a single capacitor. The topology ...
Classification of EEG recordings by using fast independent component analysis and artificial neural network
(Journal of Medical Systems, 2008)
Since there is no definite decisive factor evaluated by the experts, visual analysis of EEG signals in time domain may be inadequate. Routine clinical diagnosis requests to analysis of EEG signals. Therefore, a number of ...
Applications of parametric spectral estimation methods on detection of power system harmonics
(Electric Power Systems Research, 2008)
Harmonics are the major power quality problems in industrial and commercial power systems. Several methods for detection of power system harmonics have been investigated by engineers due to increasing harmonic pollution. ...
Work-related challenges for individuals who are visually impaired in Turkey
(Journal of Visual Impairment and Blindness, 2008)
Various aspects of the working life of people who are visually impaired were investigated in a telephone survey conducted in Turkey. Although the participants performed many types of jobs successfully, many issues need to ...
Optimality condition of a nonsmooth switching control system
(Automatic Control and Computer Sciences, 2008)
In this paper, a survey and refinement of recent results in discrete optimal control theory are presented. The step control problem depending on a parameter is investigated. Nonsmoothness of the cost function φ is assumed ...
Long term energy consumption forecasting using genetic programming
(Mathematical and Computational Applications, 2008)
Managing electrical energy supply is a complex task. The most important part of electric utility resource planning is forecasting of the future load demand in the regional or national service area. This is usually achieved ...
Hypoglycemic effect of Lentinus strigosus (Schwein.) fr. crude exopolysaccharide in streptozotocin-induced diabetic rats
(MARY ANN LIEBERT, INC, 2008)
This study reports the hypoglycemic effects of the crude exopolysaccharide (EPS) produced from submerged mycelial culture of Lentinus strigosus (Schwein.) Fr. (Family Polyporaceae) in streptozotocin (STZ)-induced diabetic ...
Hue, saturation, lightness, and building exterior preference: An empirical study in Turkey comparing architects' and nonarchitects' evaluative and cognitive judgments
(JOHN WILEY & SONS INC, 2008)
This study investigated architects' and nonarchitects' evaluative and cognitive Judgments of color on building exteriors. Thirty architects and 30 high school teachers living ill Turkey participated ill the study. The ...
Glasses and glass-ceramics in the SrO-TiO2-Al2O3-SiO2-B2O3 system and the effect of P2O5 additions
(SPRINGER, 2008)
The glass formation abilities of various compositions in SrO-TiO2-Al2O3-SiO2, SrO-TiO2-B2O3-SiO2, SrO-TiO2-Al2O3-B2O3, and SrO-TiO2-Al2O3-SiO2-B2O3 systems were studied. Many new compositions were found to be suitable for ...
