Optimization of solar air heaters of different designs
(1992)The optimum flow channel depth and mass flow rate in 10 different designs of solar air heaters have been obtained. The design variations considered are flat absorber type with and without cover glazings; single, double and ... -
Optimization of xylanase production by melanocarpus albomyces IIS68 in solid state fermentation using response surface methodology
(2001)Xylanase production by the thermophilic fungus, Melanocarpus albomyces IIS68, during solid state fermentation of wheat straw was studied and the effects of various variables were observed. Using the response surface ... -
Optimized performance of solar powered variable speed induction motor drive
(IEEE, 1996-01)This paper deals with the design and development of a photovoltaic (PV) array fed cage induction motor for an isolated water pumping system. A drive system using a chopper circuit to track power from the PV for different ... -
Optimum broadband beamforming for coherent broadband signals and interferences
(1999)The problem of optimum broadband beamforming using linear arrays is considered with a view to avoid signal cancellation that normally results when signal-correlated interferences are present in the environment. The optimum ... -
An optimum detector for coherent M-ary signaling in the presence of impulsive noise
(2000)Digital communication systems operating in the ELF/VLF range are strongly affected by atmospheric noise which has an impulsive component on a white Gaussian background. We derive an optimum detector for coherent M-ary ... -

(Elsevier Science, 1996)The paper reports the results of investigations for reduction in auxiliary power for reliable running of Indian thermal power generation plants with optimum economy and efficiency in power consumption. The problems during ... -
Optimum operating temperature and efficiency of solar thermal power systems
(1994)In this paper, finite-time thermodynamics has been applied to solar heat engines in order to find the optimum operating temperature for solar thermal power systems. The percentage difference between optimum operating ... -
Optimum pole arcs for a switched reluctance motor for higher torque with reduced ripple
(2003)In this paper, the results of a two-dimensional (2-D) finite element (FE) analysis carried out on a 8/6 switched reluctance motor with a view to arrive at the optimum pole arcs for the stator and rotor teeth are presented. ... -

Optimum tooth-geometry for specific performance requirements of a hybrid stepper motor
(2003)In this paper, a detailed account of the results of 2-D and 3-D Finite Element (FE) analyses, conducted with different tooth-width/tooth-pitch ratios (t//spl lambda/) and also with various tooth/slot shapes such as ... -
Optoelectronic architecture for cellular neural networks based on a new bias method and spatial coding scheme
(1997)A new bias method based on the concept of bias coding is proposed for cellular neural networks. A spatial coding scheme using this bias coding is then designed for arranging coded data onto transparencies to perform ... -
Organisation culture & multinational teaming: select observations in the Gulf region
(1993)If the concerns of multinational teaming are to be beamed on the fabric of organisational culture with any certitude which would lead to identification of certain generic approaches to handling projects in a borderless ... -
Orientation map: a reaction-diffusion based model
(2000)We show that models for orientation map formation, which invoke convolution in the dynamic equation, are in fact invoking non-local reaction diffusion. In the early stages of development it is unlikely that non-local ... -
