Analysis of a thermoelectric generator (TEG) in an ocean thermal energy conversion (OTEC) application is presented. An analytic model is developed for describing the heat exchanger-TEG interactions. This model is used to illustrate limitations of applying conventional fixed junction temperature assumptions to systems experiencing significant temperature drops across the heat exchanger surfaces....

To functionally compensate for an underdeveloped sarcoplasmic reticulum in immature cardiomyocytes, it has been proposed that the sarcolemmal Na+-Ca2' exchanger may assume a more predominant role for regulating cytosolic Ca2`. Previous studies using sarcolemma prepared from developing rabbit hearts demonstrated that Na+-dependent Ca2` uptake and exchanger protein content were highest at birth a...

In this paper, a fuzzy model-based algorithm is developed for leak detection in a pilot heat exchanger. A dynamic fuzzy model is first derived from input-output measurements using a fuzzy clustering technique. This model is run in parallel to the process for residual generation. The detection scheme has been tested and validated using real data from a co-current heat exchanger, and has proven t...

-In this paper, an intelligent controller is applied to electrically heated micro heat exchanger. First, the dynamics of the micro heat exchanger is identified using Locally Linear Model Tree (LOLIMOT) algorithm. Then, an intelligent controller based on brain emotional learning algorithm is applied to the identified model. Modeling emotions has attracted much attention in recent years, both in ...

This work presents an experimental approach to study the refrigerant flow through capillary tube-suction line heat exchangers. Lateral heat exchanger performance with refrigerant HFC-134a was experimentally evaluated for a range of heat exchanger assemblies and operating conditions typically found in household refrigerators and freezers. Based on the resulting performance data base, the influen...

We have cloned Calx, a gene that encodes a Na-Ca exchanger of Drosophila melanogaster. Calx encodes two repeated motifs, Calx-alpha and Calx-beta, that overlap domains required for exchanger activity and regulation. Calx has multiple transcripts in adults, including at least one expressed in the retina. The Calx genomic locus comprises >/=35 kb between the Atpalpha and rudimentary-like genes in...

In the presented paper two quality parameters are used to represent the state of a heat exchanger. The remaining lifetime can be estimated by trend regression. Also of interest is the uncertainty of the predicted lifetime which is determined by the confidence interval of the parameter estimation. These algorithms developed are used in this paper in an off-line evaluation of the measurements on ...

In this research paper in air synthesis of Psyllium and zirconium(IV)tungstoiodophosphate based organo-inorganic hybrid ion exchanger has been reported. Synthesised hybrid ion exchanger has been characterized by FT-IR, SEM, EDS and TGA/DTA/DTG and chemical composition. Ion exchange capacity and thermal studies of the synthesised ion exchanger were investigated using the potassium chloride solut...
