MDF tree is a data structure (index) that is used to speed up similarity searches in huge databases. To achieve its goal the indexes should exploit some property of the dissimilarity measure. MDF indexes assume that the dissimilarity measure can be viewed as a distance in a metric space. Moreover, in this framework is assumed that the distance is computationally very expensive and then, countin...

A sparse system identification algorithm for network echo cancellation is presented. This new approach exploits both the fast convergence of the improved proportionate normalized least mean square (IPNLMS) algorithm and the efficient implementation of the multidelay adaptive filtering (MDF) algorithm inheriting the beneficial properties of both. The proposed IPMDF algorithm is evaluated using i...

Wood and Cowan (1995) replicated and extended Moray's (1959) investigation of the cocktail party phenomenon, which refers to a situation in which one can attend to only part of a noisy environment, yet highly pertinent stimuli such as one's own name can suddenly capture attention. Both of these previous investigations have shown that approximately 33% of subjects report hearing their own name i...

Multimedia content delivery in IMS, including IPTV, is handled by a separate unit, the Media Function (MF), made up of media control and media delivery units, which in the case of IPTV are the Media Control Function (MCF) and Media Delivery Function (MDF), respectively. According to the different specifications of an IMS based IPTV architecture, the User Equipment (UE) is expected to use the RT...

This paper discusses selected properties of particleboard, hardboard, medium-densi­ ty fiberboard (MDF), and plywood related to their use in furniture and cabinet manu­ facture. Properties covered are screw-hold­ ing, internal bond, density profile, and edge appearance. Studies of direct screw with­ drawal of panel products indicate that re­ sistance to withdrawal from the edge is 75 to 80 perc...

Graphene is an advanced material in the carbon group and offers greater mechanical, electrical, structural, optical properties. oxide (GO) reduced graphene (rGO) nanoparticles were synthesized characterized their special effects on enhancing physio-mechanical characteristics of medium density fiberboard (MDF) assessed. GO rGO added to urea formaldehyde (UF) resin at different weight percentages...

This study discusses the abilities of the family of molecular descriptors on the structure-property relationships (MDFSPR) approach in modelling of the alkanes boiling points based on chemical structure information. All alkanes from C3 to C9 were included in the analysis. A MDFSPR model with two descriptors, were constructed. The MDF SPR model was validated, and its correlation coefficient was ...
