Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream of the Latian dam in Jajrood (Iran), in order to detect the contamination resulting fro...

Using firm-level data from an Enterprise Survey of World Bank, this paper is designed to test how policy variables can affect inward foreign direct investment (“FDI”) in China. After excluding the problems of sample selection and endogeneity, the result shows that investment promotion agencies (IPAs) and investment incentive zones (IIZs) have significant positive effect on absorbing FDI in Chin...

Evaluation of object detection algorithms is a non-trivial task: a detection result is usually evaluated by comparing the bounding box of the detected object with the bounding box of the ground truth object. The commonly used precision and recall measures are computed from the overlap area of these two rectangles. However, these measures have several drawbacks: they don’t give intuitive informa...

Eyes of the hoverfly Eristalis tenax are sexually dimorphic such that males have a fronto-dorsal region of large facets. In contrast to other large flies in which large facets are associated with a decreased interommatidial angle to form a dorsal "acute zone" of increased spatial resolution, we show that a dorsal region of large facets in males appears to form a "bright zone" of increased light...

As a wind turbine extracts energy from the wind, induced wind velocities, lower than the freestream velocity, will be present both upstream and downstream of the rotor. In this study, the upstream induction zone of a 225 kW horizontal axis Vestas V27 wind turbine located at the Danish Technical University’s Risø campus is investigated using a scanning Light Detection and Ranging (lidar) system....

Next Generation Air Traac Management will allow for the possibility of free ight, in which each aircraft chooses its own optimal route, altitude and speed. In a free ight environment, the trajectories of several aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. This paper presents a method for noncooperative connict resolution in which each ai...
