Traffic management in an urban area is highly facilitated by the knowledge of the traffic conditions in every street or highway involved in the vehicular mobility system. Aim of the paper is to propose a neuro-fuzzy approach able to compute the main parameters of a traffic system, i.e., car density, velocity and flow, by using the images collected by the web-cams located at the crossroads of th...

Psychological characteristics of 56 Colombian male street children, aged 7 to 16, were examined from participant observations and results of three psychological tests given the children. The Kohs Block Design measured their intelligence; and the Human Figure Drawing and the Bender Gestalt measured emotional and neurological functioning. The test data showed the sample to be relatively healthy, ...

In modern GIS applications the control of complex systems dealing with mobile objects gains more and more importance, as for example in the area of airspace monitoring, traffic monitoring on street networks, or location-based services. The logging of individual physical events, such as changes of the current position or vehicles passing a monitoring camera, results in a large amount of data, th...

Examining the effect of hedge fund activism on gender diversity, we find that number female directors decreases after a firm is targeted by activism. Using employment history data from BoardEx, activist funds are more likely to appoint people with finance backgrounds boards target firms. And newly appointed background almost all male because lack diversity in industry. The funds’ networks and q...

This paper presents a case study based on a radar interference control problem using frequency assignment as the control mechanism. The results suggest that locally autonomous agents will generally not converge to an acceptable solution and a central control using a master will converge, but at a higher cost. These results drive the need for negotiation based autonomy with some form of arbitrat...

One of the impediments to the implementation of ITS is the lack of map database interoperability. Centreline databases are available from a number of sources, but few were designed specifically for ITS. Consequently there are a variety of problems — coordinate inaccuracy, errors of omission and commission, missing or wrong street names, incorrect topology — that are compounded when communicatin...
