Increasing heterogeneity of networks and diversity of user capabilities have determined and sustained a strong interest in robust coding of visual content and flexible adaptation of the bitstreams to network and user conditions. As a result, several methods for robust coding and transmission have been proposed that include multiple description coding, motioncompensated subband video coding, joi...

This paper proposes a mechanism for the congestion control for video transmission over Universal Mobile Telecommunications System (UMTS). Our scheme is applied when the mobile user experiences real time multimedia content and adopts the theory of a widely accepted rate control method in wired networks, namely equation-based rate control. In this approach, the transmission rate of the multimedia...

A wide-band waveguide transmission system and measuring technique have been developed to obtain continuous attenuation spectra of microwaves by vegetation in the frequency range 0.8–10.0 GHz. Laboratory experiments have been performed in order to examine the spectral dependence of the attenuation by different trees and tree fragments. Some results are presented showing the distinct difference o...

Glutamatergic synaptic transmission within the striatum and prefrontal cortex regulates the neuronal synthesis of endocannabinoids. Because a primary role of dopamine is to modulate this excitatory transmission, we tested the hypothesis that dopaminergic transmission modulates endocannabinoid content in the limbic forebrain. Liquid chromatography/mass spectrometry was used to determine endogeno...

This paper describes dynamic and static measurement methods for wide-range moisture content of agricultural products such as rice and silage. The proposed method uses the attenuation and phase shift of the microwave transmitted signal through a microstrip transmission line (MSTL) sensor. The results of dynamic measurements of rice samples with low moisture content(< 18 %) showed close agreement...
