Der vorliegende Beitrag stellt die Ergebnisse eines Mitte 2006 durchgeführten Forschungsprojekts dar, in dem der potenzielle Einsatz der Radiofrequenzidentifikation (RFID) in einem Handelsunternehmen der Bekleidungsbranche wirtschaftlich analysiert wurde. Nach einer generellen Analyse des RFID-Einsatzes in der Bekleidungslogistik wurden die durch eine Prozesskostenrechnung ermittelten Kosten un...

csn1s1is one of the major genes encoding milk proteins of mammals. in this study we determined allele frequencies of csn1s1-5` flanking region as well as exon 17 variants and their effects on milk traits in three indigenous cattle breeds mazandarani, golpaygani (bos indicus) and sarabi (bos taurus) and holstein cattle in iran. csn1s1*b variant was nearly fixed in holstein but ranged from 0.40 t...

ataxia telangiectasia (at) is an autosomal recessive multi-system disorder, characterized by variable immunodeficiency, progressive neurodegeneration, occulocutaneous telangiectasia, and increased susceptibility to malignancies. this study was designed to study the role of pro-apoptotic bak, bax, nbk/bik genes in a group of patients with at to elucidate the possible role of these genes in progr...

In dual-carrier (DC)-paired fiber optic long-reach transmission, which extends a point-to-multipoint coherent system to cascaded reconfigurable optical add-drop multiplexing (ROADM) system, narrow passband causes severe performance degradation of the edge subcarriers. this study, we proposed two-dimensional frequency and polarization domain coding multicarrier-frequency control for ROADM filter...

In MPEG-4 scalable video coding, only a small portion of input data is coded in the base layer, and most signal components remain in enhancement layers. In this paper, we propose a new frequency weighting method to send more sensitive frequency coefficients faithfully with respect to the human visual system (HVS). In order to implement the frequency weighting method by bit-plane coding, we obta...

The effects of word frequency and spelling-to-sound regularity were examined using standard naming, standard lexical-decision, go/no-go naming, and go/no-go lexical-decision tasks. In both the standard and go/no-go naming tasks, tasks requiring phonological coding, a significant Frequency x Regularity interaction was observed. That is, the regularity effect was limited to low-frequency words. I...

Innerhalb des vorliegenden Beitrags wird die Anwendung der RFIDFunktechnologie in der Medikationsunterstützung im Krankenhaus anhand einer realen Umsetzung am Universitätsklinikum Jena untersucht. Hierzu werden mittels problemzentrierter Experteninterviews die praktischen Erfahrungen analysiert, um die zentralen Faktoren, die die Einführung einer RFID-Lösung beeinflussen, zu identifizieren. Ein...

ABSTRACT The third issues are compatibility and scalability. Different bitstreams, having multiple resolution versions of the image/video, are more desirable to different users with various computational capabilities. An efficient technique for hierarchical image coding is proposed, which divides an image into its multiple resolution versions with minimum hardware cost. Since the proposed techn...

OBJECTIVE To assess the auditory performance of Digisonic(®) cochlear implant users with electric stimulation (ES) and electro-acoustic stimulation (EAS) with special attention to the processing of low-frequency temporal fine structure. METHOD Six patients implanted with a Digisonic(®) SP implant and showing low-frequency residual hearing were fitted with the Zebra(®) speech processor providi...

Wavelet packet decompositions based on tree structured 2-channel filter banks with conjugate quadrature filters (CQF) have recently found many applications in the area of audio coding. Their time-frequency tiling is dual to that of timevarying modulated lapped transforms (MLT). In this paper we present a new orthonormal wavelet packet basis, which is constructed by frequency-varying MLT. These ...
