during the last two decades, financial institutions worldwide have witnessed a lot of stress in managing their margins in wake of the new risks, challenges and increase in the competition posed to them by the factors of liberalization and deregulation. the key to create value and achieve competitive edge lies in the better operational efficiency and productivity of these institutions under such...

In this paper, system operating margin (SOM) is estimated for vehicular ad-hoc networks in absence and presence of Rayleigh fading. The Ad-hoc IEEE 802.11 model is considered for estimating the signal strength and system operating margin. Rayleigh fading was then simulated and system operating margin are estimated in Rayleigh fading environment for different standard modulation schemes. Keyword...

The comparison between OCRA and the operating margin makes sense to decision maker. The operating margin (OM) shows them their ability to make and save more and more profit. The computation built in the study; help us to find the similar trend between efficiency from OCRA computation and Operating Margin from account statement. It resulted from the computation that the expected trend is obvious...

P-V or Q-V curve are commonly used to determine the maximum permissible load or static voltage stability limit of a power system. Voltage versus current relation approximation is presented as a tool to assessThe voltage stability limit.determination of the maximum permissible loading of a power system is essential for operating the system with an adequate security margin. A very simple and stra...

For a number of years, NIST has been developing a Josephson arbitrary waveform synthesizer as an ac Josephson Voltage Standard (ACJVS). The effort has primarily focused on increasing the output voltage to practical levels. Recent advances in circuit design and superconducting integrated circuit fabrication have enabled us for the first time to demonstrate waveforms with a 242 mV peak voltage. T...

The literature on the economics of airline codesharing has suggested that codeshare agreements serve to eliminate double marginalization that exists when unaffiliated airlines independently determine the price for different segments of an interline trip. Using a structural econometric model, this paper investigates whether codeshare contracts do eliminate double marginalization. The results sug...

In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary. This study examines the willingness of farm...

We make the case that ERP-related profitability improvements first manifest themselves in gross margin. Using regression discontinuity analysis, we compared “SAP Successes” with their matched competitors before and after their SAP implementation periods and found that the gross margin of SAP successes improved significantly but not their operating margin. These results proved robust across two ...
