Operations-oriented traffic signal performance measures are important for identifying the need retiming to improve operations. Currently, most obtained from high-resolution controller event data, which provides information on an intersection-by-intersection basis and requires significant initial capital investment. Over 400 billion vehicle trajectory points generated each month in United States...

This study examines the maritime security strategies adopted by Nigerian government to ensure maximum in Nigeria domain. The looked at as preventive and responsive actions guard against threats intended illegitimate acts Nigeria. It tries evaluate strategy operational performance under Fourth Republic. relies on secondary data with leverage content analysis examining literature concerning fourt...

At present, methods are well established for measuring the performance of sensors, such as sonars and radars, in an experimental environment. However, the results of these measurements are not necessarily indicative of the sensors' performance under operational conditions. A method is developed, whereby, the operational effectiveness of sensors is determined directly from data obtained from ope...

heat exchangers are the critical components of refrigeration and liquefaction processes. selection of appropriate operational conditions for cryogenic recuperative heat exchanger and expansion valve operating in joule-thomson cooling system results in improving the performance and efficiency. in the current study, a straightforward procedure is introduced to design an efficient joule-thomson co...

what are the main success factors of microfinance institutions in providing financial services to poor people in a sustainable manner? in this article we try to answer this question. in one hand, we analyze the core compatibility between microeconomics of asymmetric information, transaction cost and risk, and new different operational mechanisms applied by microfinance institutions. on the othe...

The impact of operational performance on airline cost structure is empirically investigated using an aggregate, statistical cost estimation approach. Two distinct sets of operational performance metrics are developed and incorporated into the airline cost models as arguments. Results from estimating a variety of airline cost models reveal that both delay and schedule buffer are important cost d...
