Emissions of air pollutants in and around urban areas lead to negative health impacts on the population. To estimate these impacts, it is important to know the sources and transport mechanisms of the pollutants accurately. Mexico City has a large urban fleet in a topographically constrained basin leading to high levels of carbon monoxide (CO). Large point(More)
A new, photocell-equipped, activity meter is described. The motor activity is observed in a large square, "open field", arena (approximately 0.5 m2) suited for activity observations of rats or other similarly sized animals. Horizontal and vertical activity is recorded at two levels (8 x 8 photocells at each level). Information from each photocell,(More)
A new PC-controlled two-way avoidance conditioning equipment for rats is described. The position of the rat within the two-compartment shuttle-box is monitored by means of 4 + 4 horizontal photocell beams. Experimental conditions and procedures, such as CS-UCS interval, photocell operations, shock strength, and so on, can conveniently be preset by the(More)
The Linked Dipole Chain Model provides an interpolation between the regions of high Q 2 (DGLAP) and low x-moderate Q 2 (BFKL) in DIS. It is a reformulation and a generalization of the results obtained by Ciafaloni, Catani, Fiorani and Marchesini, and it gives a uniied treatment of \normal DIS", boson-gluon fusion events and hard subcollisions in resolved(More)

The emergence of heterogeneous networks and the rapid increase of Voice over IP (VoIP) applications provide important opportunities for the telecommunications market. These opportunities come at the price of increased complexity in the monitoring of the quality of service (QoS) and the need for adaptation of transmission systems to the changing(More)
We consider a new approximation scheme to the perturbative QCD cascades, Discrete QCD, corresponding to an expansion in the phase space density of the emitted partons. It turns out that this density in phase space is very low and the reason can be traced to the physics behind the running coupling constant. The whole scheme only contains a single parameter,(More)
We have in an earlier paper, 1], presented a generalization, the Linked Dipole Chain Model LDC, of the model developed by Ciafaloni-Catani-Fiorani-Marchesini, 2], to de-cribe the structure functions and the states in Deep Inelastic Scattering events. In this paper we would like to present an investigation of a set of general features of the LDC Model, viz(More)

In mobile speech communication, adverse conditions, such as noisy acoustic environments and unreliable network connections, may severely degrade the intelligibility and naturalness of the received speech quality, and increase the listening effort. This thesis focuses on countermeasures based on statistical signal processing techniques. The main body of the(More)
