Journal ArticleDOI
TL;DR: A class of fault-tolerant multistage interconnection networks named as Augmented Baseline Networks (ABNs) is introduced, which achieve a significant improvement over unique-path MINs and compare favorably with other multiple path MINs.

Journal ArticleDOI
TL;DR: In this article, a nonlinear programming framework for examining the objective constraint level in an ϵ-constant form of the multi-objective optimization problem is presented, where the dispersion index is chosen as the sensitivity measure for the investigation of the effects of random variations in the model parameters of the optimal solution.

Journal ArticleDOI
TL;DR: In this paper, the use of Rhodococcus fascians for debittering kinnow juice was explored, and its growth and application conditions were optimized for optimal degradation of limonin at 25°C, pH 4.0 and 150 rev min -1 for 48 h.

Journal ArticleDOI
TL;DR: A vegetable protein/oil industry waste product has afforded a value-added, biodegradable, non-phytotoxic, user-friendly and import-substitute plant growth regulator, PGR-101, and simultaneously reduced pollution as mentioned in this paper.

Journal ArticleDOI
TL;DR: In this article, a theoretical model of the diffusion of barium from the generating to the emitting sites of the cathode has been developed from the general considerations of diffusion as well as the fundamental nature of the barium surface migration.

Journal ArticleDOI
TL;DR: In this paper, anaerobic treatment of prehydrolysate from eucalyptus stems has been explored using active seed cultures (vol. 5 litres) from cattle dung, poultry waste and domestic sewage sludge.

TL;DR: In this article, a shortpitch (spl rho/sub 0/=0.43 /spl mu/m), large spontaneous polarization (P/sub s/=90 nC/cm/sup 2/) ferroelectric liquid crystal mixture was studied in the form of thin films sandwiched between polyimide coated transparent conducting glass plates.
Abstract: Electro-optic effects have been studied in a shortpitch (/spl rho//sub 0/=0.43 /spl mu/m), large spontaneous polarization (P/sub s/=90 nC/cm/sup 2/) ferroelectric liquid crystal mixture. The material in the form of thin films was sandwiched between polyimide coated transparent conducting glass plates. The sample alignment was planar in an electric field without shearing. Disclination loops appeared at low voltages and were then removed at higher voltages to obtain a 'bookshelf' structure which gives higher contrast. This material shows bistability, fast switching times (40 /spl mu/sec at 8 V//spl mu/m) and multiplexability. These are useful parameters for the operation of a fast electro-optic liquid crystal display device.

TL;DR: In this paper, Broca et al. examined the stability of the volatility or risk parameter using weekly market data over 1990-91 in respect of 17 emerging markets identified by the International Finance Corporation.
Abstract: The volatility or risk parameter, usually defined as the standard deviation of stock returns, forms the cornerstone of contemporary finance theories. Reliability of results obtained from various financial decision making models depends on the stability, finiteness, and accuracy of risk estimates. This paper by Broca examines the stability of this parameter using weekly market data over 1990-91 in respect of 17 emerging markets identified by the International Finance Corporation. Through an application of nonparametric test procedures, the study detects variance heterogeneity for 6 out of 17 markets. Though not pervasive, a review of major political-economic events over the sample period, with special reference to the Gulf crisis of August 1990, is attempted to partly validate empirical findings.
