Analysis and stochastic characterization of TCP flows
Aracil Rico, Javier; Morató Osés, Daniel ; Izal Azcárate, Mikel (Springer, 2000)
Artículo / Artikulua
Since the most Internet services use TCP as a transport protocol there is a growing interest in the characterization of TCP flows. However, the flow characteristics depend on a large number of factors, due to the complexity ... -
Analysis of Internet services in IP over ATM networks
Aracil Rico, Javier; Morató Osés, Daniel ; Izal Azcárate, Mikel (IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena
This paper presents a trace-driven analysis of IP over ATM services from a user-perceived quality of service standpoint. QoS parameters such as the sustained throughput for transactional services and other ATM layer ... -
Application of the L-fuzzy concept analysis in the morphological image and signal processing
Alcalde, Cristina; Burusco Juandeaburre, Ana ; Fuentes González, Ramón (Springer International Publishing, 2014)
Artículo / Artikulua
In this work we are going to set up a new relationship between the L-fuzzy Concept Analysis and the Fuzzy Mathematical Morphology. Specifically we prove that the problem of finding fuzzy images or signals that remain ... -
