چکیده

The main qualities of a protocol for multimedia flows transportation are related to the way congestions are handled. This paper addresses the problem of endto-end congestion control performed in the Internet transport layer. We present a simple protocol called Primo, that determines the appropriate sending rate in order to maximize network resources usage and minimize packets loss. Comparison with existing transport protocols (TCP Reno, Sack, Vegas and TFRC) are considered, regarding various efficiency criteria such as sending and reception rates stability, loss rate, resources occupancy rate and fairness. Abstract— Les principales qualités d’un protocole pour les flots multimédia concernent la gestion des congestions. Cet article s’intéresse au problème du contrôle de congestion de bout en bout effectué dans la couche transport d’Internet. Nous présentons un protocole simple appelé Primo, qui détermine le taux d’émission approprié dans le but de maximiser l’utilisation des ressources réseaux et de minimiser la perte des paquets. Des comparaisons avec des protocoles de transport existants (TCP Reno, Sack, Vegas et TFRC) sont analysées en prenant en compte différents critères tels que la stabilité des débits d’émission et de réception, le taux de perte, l’occupation des ressources et l’équité.

Systematic integrated approach to quantifying preventive diagnostics in a “smart” transport system

One of the main tasks facing all European countries for the next few years is the creation of the most dynamically organized transport sector. The constant passenger and freight traffic lead to congestions and pollutions at the transport highways, having negative impact on a person. Thus, introduction of new technologies, addressing the interrelated problems of optimizing transport flows and im...

Development of Simple Protocol for Generation of Functionally Active Hepatocyte-like Cells from Human Adipose Tissue-derived Stem Cells

Background and Aims: Human adipose tissue-derived stem cells (hASCs) are considered as an attractive source of regenerative stem cells, mainly because of their higher proliferation rate, more accessibility and hepatocyte like properties as compared to mesenchymal stem cells isolated from other tissues. Numerous studies have described the beneficial use of adipose tissue-derived stem cells for g...

An efficient and simple CTAB based method for total genomic DNA isolation from low amounts of aquatic plants leaves with a high level of secondary metabolites

An efficient DNA isolation protocol specifically modified to get pure quality DNA required for molecular studieshas been reported in this paper. Some aquatic plants (Potamogeton spp., Ceratophyllum demersum and Myriophyllum spicatum) were used for the study. The protocol developed will be useful in getting high and pure DNA. Instead of using the available DNA extraction kits, this protocol can ...

A simple and efficient DNA extraction protocol for old herbarium leaves of Bellevalia (Asparagaceae, Scilloideae)

High-quality DNA extraction plays an important role to make sharp bands in the gel electrophoresis and also produces clean chromatograms. Usually, DNA extract is delivered using the modified CTAB method but this method cannot obtain high-quality DNA for molecular analysis from old dried leaves of Bellevalia due to having different chemical compounds which inhibit to obtain a clear DNA extractio...

Introducing a New and Simple Protocol for Capillary Electrophoresis of Cell Free Fetal Double Stranded DNA

Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...
