Separation of Heavy Water from Water-Isotopes Mixture in Flat-Plate Thermal Diffusion Columns with Transverse Sampling Streams and Optimal Plate Spacing
2009Co-Authors: Ho-ming YehAbstract:The effects of plate spacing on the separation of heavy water from water-isotopes mixture in flat-plate thermal diffusion columns with transverse sampling stream, have been investigated. Considerable improvement in performance with fixed Operating Expense is obtainable if the plate spacing is suitably adjusted, resulting in suppressing the undersirable remixing effect while still preserving the desirable cascading effect.

Effects of Inclined Angle and Plate Spacing on the Degree of Separation in Batch-Type Flat-Plate Thermal Diffusion Columns
Chemical Engineering Communications, 2002Co-Authors: Ho-ming YehAbstract:Effects of inclined angle and plate spacing on the degree of separation in batch-type flat-plate thermal diffusion columns, with Operating Expense and fixed charge kept unchanged, are discussed. It was found that the degree ofseparation increases when the inclined angle increases or when the platespacing decreases. However, decreasing the plate spacing will lead to decreasingthe amount of solution to be treated in the column, while increasing the inclined angle will enlarge the Operating time for reaching the steady state.

THE COMBINED EFFECT OF INCLINED ANGLE AND PLATE SPACING ON THE PERFORMANCES OF FLAT-PLATE THERMAL-DIFFUSION COLUMNS
Chemical Engineering Communications, 2000Co-Authors: Ho-ming YehAbstract:Abstract When the separation is performed in a parallel-plate thermal diffusion column with the Operating Expense fixed, either increasing the plate spacing and Operating at the corresponding optimum inclined angle, or increasing inclined angle and Operating at the corresponding plate spacing, will increase the maximum separation and maximum production rate. Il was found that the cosine of optimum inclined angles increase with the plate spacing in the exponents of -9/2 and —4, respectively, for maximum separation and maximum production rate, while the optimum plate spacings increase with the cosine of inclined angle in the exponents of -2/9 and — 1/4, respectively. The plate spacing is generally so small that changing it, as well as changing the inclined angle, may not cause additional fixed change. However, increasing the plate spacing will lead to increasing the difference of plate temperatures in order to keep the Operating Expense, as well as the energy consumption due to heat conduction between the h...

THE OPTIMUM PLATE-SPACING FOR THE BEST PERFORMANCE IN FLAT-PLATE THERMAL DIFFUSION COLUMNS OF THE FRAZIER SCHEME
Chemical Engineering Communications, 1998Co-Authors: Ho-ming YehAbstract:Abstract The effect of plate spacing on the degree of separation and production rate in flat-plate thermal diffusion columns of the Frazier scheme with fixed Operating Expense, has been investigated. The equations for estimating optimum plate-spacing for maximum separation and for maximum production rate have been developed. Considerable improvement in performance is obtainable when the thermal diffusion columns with optimum plate-spacing are employed for operation.

THE OPTIMUM PLATE-SPACING FOR THE BEST PERFORMANCE IN A FLAT-PLATE THERMAL DIFFUSION COLUMN WITH TRANSVERSE SAMPLING STREAMS
Chemical Engineering Communications, 1997Co-Authors: Ho-ming YehAbstract:The equations for estimating optimum plate-spacing for maximum separation and for maximum production rate in a flat-plate thermal diffusion column with transverse sampling stream and with fixed Operating Expense, have been derived. Considerable improvement in performance is obtainable if the optimum plate-spacing is selected so that the convective strength can be properly reduced and controlled, resulting in suppressing the undesirable remixing effect while still preserving the desirable cascading effect and thereby leading to improved performance.

Is There Excess Capacity in Rural Banking Markets
The Financial Review, 1998Co-Authors: James E. Mcnulty, Aigbe AkhigbeAbstract:The literature indicates that it is difficult to identify and quantify the degree of excess capacity in banking. Economic theory indicates that there are at least three indicators of excess capacity in banking: (a) low loan-to-asset ratios, (b) low profitability, and (c) high per unit Operating Expense relative to some norm. If excess capacity exists, it will be easiest to identify, through these indicators, at small rural banks. This paper finds significant evidence of excess capacity at rural Colorado banks using univariate analysis; simultaneous equations analysis reinforces this conclusion. It appears that the "excess capacity effect" outweighs the "market power effect" in these rural banking markets. Copyright 1998 by MIT Press.

ANALISIS PENGARUH STRUKTUR MODALTERHADAP PROFITABILITASBANK SYARIAH
2016Co-Authors: Ammar Nashir, Faisal FaisalAbstract:This research aims to analyze the influence of consumer and short-term funds, Capital Ratio, risk, Operating Expense, and Size toward profitability of Islamic Banks in Indonesia which was proxied by Return on Assets (ROA). The data used in this research were obtained from Financial Report of Islamic Banks annually publication through each website. The sampling technique was purposive sampling with Islamic Banks that published annually financial report periodically during the observation period of 2010-2014 as criteria. Data was analized using Ordinary Least Square (OLS). The result of this research show that the independent variables significantly affect ROA. While capital ratio, consumer and short-term funds, and size do not affect ROA. Furthermore risk and Operating Expense affect negatively on ROA.

Analisis Agency Cost, Struktur Kepemilikan dan Mekanisme Corporate Governance
International Journal of Approximate Reasoning, 2005Co-Authors: Faisal FaisalAbstract:This paper examines the relationship between ownership structure, corporate governance and agency costs measured in terms of asset utilization and Operating Expense. This paper based on the previous research by Ang et al. (1999) and Singh et al. (2003). I utilize a sample of 96 firms from Jakarta Stock Exchange for periods of 1999-2001. Univariate results show that firms with high managerial ownership are more efficient in their asset utilization than firms with low managerial ownership, but the difference is insignificant. Firms with high institutional ownership and large size of boards are significantly more efficient than low those of institututional ownership and small size of boards. Multivariate results fail to confirm that managerial and institutional ownership have potential effect to agency costs (asset utilization and Operating Expense). However, I find there is a positive relationship between board size and asset utilization and negative relationship to Operating Expense. This evidence is consistent with the notion that large boards are effective to monitor firm performance.

Firm size and the information technology investment intensity of life insurers
MIS Quarterly, 1991Co-Authors: Sidney E. Harris, Joseph L. KatzAbstract:This article is organized around two research questions: (1) do small insurers exhibit a higher degree of information technology investment intensity (i.e., the ratio of information technology Expense to total Operating Expense) than large insurers? and (2) to what extent dos the level of spending on information technology explain the degree of information technology investment intensity? The article offers an interpretation of the dependent and independent variables and uses data obtained from the life insurance industry. The findings on the whole indicate that small insurers spend a larger proportion of their Operating Expenses on information technology than do large insurers. Given the conditions prevailing in the life insurance industry, this means that large firms were not leaders in realizing the full potential of the economic benefits available. Contrary to expectations, spending more on information technology does not lead to a higher ratio of information technology Expense to total Operating Expense. This finding is consistent with the observation by several academics and practitioners that how the technology is used and managed is of equal if not more important consideration than the level of spending.
