Operational speed is an index that represents drivers’ speeding behaviors and shows the comfort and safety levels they experience. Many models had been proposed to predict operational speed in tangent and curve segments of highways. Most of these works had used geometric, with few of them conducted using roadside variables to predict operational speed. Also, the operational speed study in multi...

This article deals with the operational use of a domain ontology integrated into a Knowledge-Based System (KBS). It presents TooCoM, a tool dedicated to (1) the definition of ontologies with the Entity-Relationship paradigm and (2) the operationalization of ontologies in the context of the Conceptual Graphs model. TooCoM provides functionalities for specifying an operational scenario of use of ...

introduction gotvand-olia as one of the largest constructional projects in iran has been constructed on the karoun river, between masjed soleiman and gotvand regulatory dam in khuzestan province. it is situated in 382.8 km away from the river estuary at a distance of 25 km north of shoushtar city. this study was conducted to identify and assess the risk of gotvand-olia dam on the environment at...

a r t i c l e i n f o Operational risk is increasingly being recognised as a significant area of risk and regulation, yet there exists relatively little research on it. In this paper we show that operational risk represents a fundamental risk to option hedging and investigate it by proposing a new theoretical model. We derive an exposure indicator for the operational risk of option hedging and ...

We show that the operational transconductance amplifier (OTA), as the active element in basic bnilding blocks, can be efficiently used for programmable nonlinear continuous-time function synthesis. Two efficient nonlinear function synthesis approaches are presented. The first approach is a ratiossaf approximation and tbe second is a piecewise.linear approach. Test circuits have been fabricated ...

Some preliminary results about the verification and validation of SCIAMACHY’s Absorbing Aerosol Index (AAI) are presented. The operational AAI level 2 product of SCIAMACHY is compared to our own AAI algorithm, developed at KNMI. The operational product shows general agreement with the KNMI algorithm but both suffer from large errors in reflectancees, resulting in a large off-set. Also, the negl...

Review the literature of conservatism in financial reporting indicates the importance of conservatism in accounting profession. Researchers have always tried to determine the degree and ways of conservatism in financial reporting and accounting, although this is not done easily, because there is not a direct measure of conservatism. However, conservatism has been one of the key principles in ac...
