A comparison study of evolutive algorithms for solving the partitioning problem in distributed virtual environment systems

2004

Fast Internet connections and the widespread use of high performance graphic cards are making Distributed Virtual Environment (DVE) systems very common nowadays. However, there are several key issues in these systems that should still be improved in order to design a scalable and cost-effective system. One of these key issues is the partitioning problem. This problem consists of efficiently assigning clients (3D avatars) to the servers in the system. In this paper, we present a comparison study of different modern heuristics for solving the partitioning problem in DVE systems, as an alternative to the ad hoc heuristic proposed in the literature. Performance evaluation results show that some…

A Comparison Study of Modern Heuristics for Solving the Partitioning Problem in Distributed Virtual Environment Systems

Integrated multimedia publishing: combining TV and newspaper content on personal channels

1999

Abstract Fast networks enable the delivery of TV and newspaper content over an Internet connection. This enables new types of integrated publications that include features from both media. The IMU system, described in this paper, automatically integrates newspaper and TV content into a continuously updated World Wide Web-multimedia publication. An active proxy server pursues the integration and delivers the publication through an ATM fibre link to fast networks, such as the bi-directional cable TV network and the ADSL telephone network, providing near-TV quality. The users read the IMU publication from the Internet on their PCs with normal World Wide Web-browsers. You can also watch the pub…

Aproximaciones en la preparación de contenido de vídeo para la transmisión de vídeo bajo demanda (VOD) con DASH

2023

El consumo de contenido multimedia a través de Internet, especialmente el vídeo, está experimentado un crecimiento constante, convirtiéndose en una actividad cotidiana entre individuos de todo el mundo. En este contexto, en los últimos años se han desarrollado numerosos estudios enfocados en la preparación, distribución y transmisión de contenido multimedia, especialmente en el ámbito del vídeo bajo demanda (VoD). Esta tesis propone diferentes contribuciones en el campo de la codificación de vídeo para VoD que será transmitido usando el estándar Dynamic Adaptive Streaming over HTTP (DASH). El objetivo es encontrar un equilibrio entre el uso eficiente de recursos computacionales y la garantí…

Characterizing Web sessions of e-customers interested in traditional and innovative products

2016

Web traffic characterization and modelling is currently a hot research issue. Low-level analysis of HTTP traffic on the server allows one to build adequate traffic models to be used in server benchmarking. High-level analysis of Web user behavior allows one to optimize website structure and develop personalized service strategies. In this paper, analysis of customer sessions in an online store is performed using Web server log data. The goal is to explore possible differences between sessions of customers viewing and purchasing innovative products, and customers only interested in traditional products.

Apimation testēšanas datu menedžmenta API servera esošā koda pārrakstīšana vairākās komponentēs

2018

Darba mērķis ir optimizēt esošo Apimation testēšanas datu pārvaldes API serveru, pārrakstot to Go programmēšanas valodā un sadalot to atsevišķās komponentēs. Darba uzdevumi – izveidot efektīvāku un drošāku datu pārvaldes serveri Apimation testēšanas rīkam. Apimation ir HTTP protokola tīmekļu servisu testu automatizācijas rīks, kas tiek izmantots funkcionālitātes un veiktspējas testēšanai. Savukārt Apimation testēšanas datu pārvaldes API serveris ir šī rīka pamatdaļa, atbild par testēšanas datu pārvaldību, izmantojot autentifikācijas serveri kā resursu aizsardzības mehānisma nodrošinājumu.

"BindingMap" sinhronizācijas uzlabojumi ietvarā "GWTExt"

2015

Maģistra darbā tiek apskatīts tīmekļa ietvarā „GWTExt” esošās „BindingMap” tehnoloģijas sinhronizācijas problēmas starp klienta un servera pusēm, kā arī autora izveidotie risinājumi šai problēmai. Pirms šī darba izstrādes visi lietotnes formā esošie dati starp klienta izsaukumiem tika glabāti tikai klienta pusē, kas noveda gan pie ātrdarbības problēmām, pie katra izsaukuma sūtot visu datu kopu serverim, gan iespējamām drošības problēmām, lietotājam manipulējot ar pieejamo datu kopu. Darba rezultātā ir samazināts datu apjoms kāds ir jāsūta, lai datus sinhronizētu starp klientu un serveri, izveidots mehānisms kā saglabāt servera stāvokli starp klienta izsaukumiem, kā arī palielināta ietvara d…

Inter- and Intraobserver Variation in the Assessment of Preoperative Colostograms in Male Anorectal Malformations: An ARM-Net Consortium Survey

2020

Aim:Male patients with anorectal malformations (ARM) are classified according to presence and level of the recto-urinary fistula. This is traditionally established by a preoperative high-pressure distal colostogram that may be variably interpreted by different surgeons. The aim of this study was to evaluate the inter- and intraobserver variation in the assessment by pediatric surgeons of preoperative colostograms with respect to the level of the recto-urinary fistula. Materials and Methods:Sixteen pediatric surgeons from 14 European centers belonging to the ARM-Net Consortium twice scored 130 images of distal colostograms taken in sagittal projection at a median age of 66 days of life (rang…
