Hierarchical Parallelization of an H.264/AVC Video Encoder
2006
Last generation video encoding standards increase computing demands in order to reach the limits on compression efficiency. This is particularly the case of H.264/AVC specification that is gaining interest in industry. We are interested in applying parallel processing to H.264 encoders in order to fulfill the computation requirements imposed by stressing applications like video on demand, videoconference, live broadcast, etc. Given a delivered video quality and bit rate, the main complexity parameters are image resolution, frame rate and latency. These parameters can still be pushed forward in such a way that special purpose hardware solutions are not available. Parallel processing based on…
Lactococcal 949 group phages recognize a carbohydrate receptor on the host cell surface
2015
ABSTRACT Lactococcal bacteriophages represent one of the leading causes of dairy fermentation failure and product inconsistencies. A new member of the lactococcal 949 phage group, named WRP3, was isolated from cheese whey from a Sicilian factory in 2011. The genome sequence of this phage was determined, and it constitutes the largest lactococcal phage genome currently known, at 130,008 bp. Detailed bioinformatic analysis of the genomic region encoding the presumed initiator complex and baseplate of WRP3 has aided in the functional assignment of several open reading frames (ORFs), particularly that for the receptor binding protein required for host recognition. Furthermore, we demonstrate th…
Dynamic Packet Bundling for VoIP Transmission Over Rel'7 HSUPA with 10ms TTI Length
2007
In this paper, the system level optimization of the voice over IP transmission in the HSUPA system, configured with a 10 ms TTI length, is analyzed. The study considers the release 7 improvements to HSUPA, in terms of the DPCCH gating concept. A dynamic activated MAC layer bundling of two VoIP packets in a single frame is proposed and compared against the single packet per frame transmission by means of quasi-static system level simulations.
Cyanido-Bridged FeII-MI Dimetallic Hofmann-Like Spin-Crossover Coordination Polymers Based on 2,6-Naphthyridine
2017
[EN] Two new 3D spin-crossover (SCO) Hofmann-type coordination polymers {Fe(2,6-naphthy)[Ag(CN)2][Ag2(CN)3]} (1; 2,6-naphthy = 2,6-naphthyridine) and {Fe(2,6-naphthy)- [Au(CN)2]2}·0.5PhNO2 (2) were synthesized and characterized. Both derivatives are made up of infinite stacks of {Fe[Ag(CN)2]2- [Ag2(CN)3]}n and {Fe[Au(CN)2]2}n layered grids connected by pillars of 2,6-naphthy ligands coordinated to the axial positions of the FeII centers of alternate layers.
Atskaišu sistēma kokvedēja vadītājiem
2022
Lietotnes “Atskaišu sistēma kokvedēja vadītājiem” mērķis ir atvieglot loģistikas speciālistu komunikāciju ar kokvedēju vadītājiem, sniedzot minētajiem vadītājiem iespēju ērti sniegt atskaites par veicamā darba statusu. Izstrādātā sistēma apkopo informāciju par katra vadītāja tā brīža pildītajiem darba pienākumiem un ļauj loģistikas speciālistiem plānot un uzdot vadītājiem tālākos darba pienākumus. Sistēma datus glabā datubāzē un tos lietotājam pasniedz viegli pārskatāmā veidā, atvieglojot to pārvaldību. Sistēma sastāv no “Windows Presentation Foundation” lietotāja saskarnes satvara, “Entity Framework” relāciju kartēšanas sistēmas un "Microsoft SQL Server" datu bāzes pārvaldības sistēmas.
Connectivity in hydrology and sediment dynamics
2020
Connectivity has emerged as a significant conceptual framework for understanding the transfer of surface water and sediment through landscapes. The concept has been widely adopted in the field of catchment hydrology but has also been valuable to investigate rates of soil erosion by water and sediment export across landscapes. To study connectivity, we gathered a group of scientists that worked on synthesizing and consolidating all theories and aspects of connectivity research. Within the EU-funded ESSEM COST Action CONNECTEUR (ES1306), five working groups were established: (a) theory, (b) measuring, (c) modelling, (d) indices, and (e) society. One of the outputs of this COST Action is this …
Theoretics and Methodology
2016
Since 2000 in Europe an integrated management framework has been developed to innovate exploitation and safeguard of water resources. In this context the EU Water Framework Directive has identified the hydrographic basin as the optimal territorial unit for promoting new participatory policies, based both on the interaction of stakeholders and the coordination of sectorial instruments. In this scenario, river contracts assumed a strategic role both in addressing these purposes and supporting the dialogue and integration between interests of public and private stakeholders. This chapter illustrates the theoretical and methodological framework, and the comparative approach on which the researc…
Environmental Benefits of Wastewater Treatment: An Economic Valuation
2009
The need of economic research into the design and implementation of policies for the efficient management of water resources has been emphasized by the European Water Framework Directive (Directive 2000/60/UE). The efficient implementation of policies to prevent the degradation and depletion of water resources requires determining their value in social and economic terms and incorporating this information into the decision-making process. A process of wastewater treatment has many associated environmental benefits. However, these benefits are often not calculated because they are not set by the market. Nevertheless, the valuation of these benefits is necessary to justify a suitable investme…
Characterisation of nonoriented electric alloys under nonconventional conditions
1996
The variations of magnetic and loss characteristics of nonoriented cobalt-iron and silicon-iron sheets have been investigated using an Epstein frame. Cobalt-iron alloys have been tested under sinusoidal magnetic flux density with respect to frequency and temperature. Both kinds of alloys have also been investigated with respect to frequency, time constant wavefront and temperature under trapezoidal flux density. The qualitative behaviour is identical under both flux density conditions for all these alloys. These investigations have made it possible to model the variations of iron losses with experimental parameters, except the temperature. These quantitative evolutions differ with alloy and…
Semantic Web Services for Smart Devices in a “Global Understanding Environment”
2003
Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…
