Energy and exergy analyses in a rotary burner with pre-calcinations in cement production
(Pergamon-Elsevier Science Ltd, 2004)
Cement production facilities are often located in rural areas and close to quarries, where the raw materials required for cement production are present, i.e. limestone and shale. Although energy analysis, based on the first ...
A study for estimating solar resources in Turkey using artificial neural networks
(Taylor & Francis Inc, 2004)
Turkey has sufficient solar radiation and radiation period for solar thermal applications since it lies in a sunny belt between 36degrees and 42degreesN latitudes. The yearly average solar radiation is 3.6 kWh/m(2) day, ...
Performance prediction of a vapour-compression heat-pump
(Elsevier Sci Ltd, 2004)
The performance of the heat pump was predicted using a fuzzy-logic controller under various working-conditions and mixing ratios of R12/R22 refrigerant mixtures, instead of requiring an expensive and time consuming ...
Design of a circular piezoelectric transformer with crescent-shaped input electrodes
(Inst Pure Applied Physics, 2003)
In this study, a new disk-type piezoelectric transformer design is proposed. The input side of the transformer has a crescent-shaped electrode and the output side has a focused poling direction. The electrodes and poling ...
Effects of NaOCl on bond strengths of resin cements to root canal dentin
(Lippincott Williams & Wilkins, 2003)
Microleakage occurs due to the lack of sealing ability of root sealing materials or adhesive cements used to lute post-core materials. This may cause premature failure of endodontic treatment. The purpose of this study was ...
A new approach to thermodynamic analysis of ejector-absorption cycle: artificial neural networks
(Pergamon-Elsevier Science Ltd, 2003)
Thermodynamic analysis of absorption thermal systems is too complex because of analytic functions calculating the thermodynamic properties of fluid couples involving the solution of complex differential equations. To ...
Light and heavy water cooled hybrid reactors for rejuvenation of LWR spent fuels
(Pergamon-Elsevier Science Ltd, 2003)
This study analyzes the rejuvenation performance and energy production of D-T driven hybrid blankets fueled by LWR spent fuel and cooled by heavy water (D2O) and light water (H2O). A fuel zone is placed between two cylindrical ...
The effect of stacking sequence of carbon epoxy composite laminates on pinned-joint strength
(Elsevier Sci Ltd, 2003)
In this paper, an experimental study regarding the determination of the safe as well as the maximum bearing strengths of a pinned-joint carbon epoxy composite laminate with [0degrees/45degrees/-45degrees/90degrees]s and ...
Recycling of cutting tools in flexible manufacturing systems
(Taylor & Francis Ltd, 2003)
Flexible manufacturing systems (FMS) are complex, with a high variety of entities. In particular, tool management is critically important for timely manufacture. Since a large number of tools flow in a medium-size FMS, it ...
