A simple passive method to estimate RTT in high bandwidth-delay networks
This paper presents a simple passive algorithm to estimate the Round-Trip-Time (RTT) of a TCP connection in high bandwidth-delay network scenarios. In these scenarios, a passive RTT estimator that can be used on captured ... -
Some characterizations of lattice OWA operators
Ordered Weighted Averaging (OWA) operators are a family of aggregation which fusion data. If the data are real numbers, then OWA operators can be characterized either as an special kind of Choquet integral or simply as an ... -
Some properties of implications via aggregation functions and overlap functions
In this work, using the identification between implication operators and aggregation functions, we study the implication operators that are recovered from overlap functions. In particular, we focus in which properties ... -
Stability of time-delay systems via Lyapunov functions
In this paper, a Lyapunov function candidate is introduced for multivariable systems with inner delays, without assuming a priori stability for the nondelayed subsystem. By using this Lyapunov function, a controller is ... -
The study of fuzzy context sequences
In some cases, the relationship between an object set X and an attribute set Y is set up by means of a fuzzy context sequence. A particular case of this situation appears when we want to study the evolution of an L-fuzzy ... -
A survey of fingerprint classification Part I: taxonomies on feature extraction methods and learning models
This paper reviews the fingerprint classification literature looking at the problem from a double perspective. We first deal with feature extraction methods, including the different models considered for singular point ... -
A survey of fingerprint classification Part II: experimental analysis and ensemble proposal
In the first part of this paper we reviewed the fingerprint classification literature from two different perspectives: the feature extraction and the classifier learning. Aiming at answering the question of which among the ... -
A survey on fingerprint minutiae-based local matching for verification and identification: taxonomy and experimental evaluation
Fingerprint recognition has found a reliable application for verification or identification of people in biometrics. Globally, fingerprints can be viewed as valuable traits due to several perceptions observed by the experts; ... -
TBDClust: time-based density clustering to enable free browsing of sites in pay-per-use mobile Internet providers
The World Wide Web has evolved rapidly, incorporating new content types and becoming more dynamic. The contents from a website can be distributed between several servers, and as a consequence, web traffic has become ... -
Techniques for better alias resolution in Internet topology discovery
One of the challenging problems related with network topology discovery in Internet is the process of IP address alias identification. Topology information is usually obtained from a set of traceroutes that provide IP ... -
Técnicas eficientes de filtrado de tráfico para monitorización de redes de comunicaciones
Las necesidades de intercambio de datos han crecido de manera espectacular en los últimos años y con ello la infraestructura de telecomunicaciones asociada. Además, la aparición de nuevos servicios ha requerido cada vez ... -
Técnicas eficientes de filtrado y análisis de tráfico para la monitorización continua de redes de comunicaciones
This paper presents an efficient traffic filtering and analysis architecture for network monitoring. Opposed to the usual network monitoring architectures that provide simultaneous filters as requested by managers (packet ... -
A theorem for constructing interval-valued intuitionistic fuzzy sets from intuitionistic fuzzy sets
(Institute of Biophysics and Biomedical Engineering, Bulgarian Academy of Sciences, 1995) Artículo / ArtikuluaIn this paper we present a theorem that allows us to construct interval-valued intuitionistic fuzzy sets from intuitionistic fuzzy sets. We also study the way of recovering intuitionistic fuzzy sets used in the construction ... -
TNS research in progress

Last two papers sent to major conferences are ... -
Traffic estimation in high-speed communication networks using fuzzy systems
We present a practical application of fuzzy systems in communication networks. In this case a fuzzy relational model is developed to estimate the bytes transferred every time unit over a communication link. Such estimation ... -
Traffic generator using Perlin Noise
Study of high speed networks such as optical next generation burst or packet switched networks require large amounts of synthetic traffic to feed simulators. Methods to generate self-similar long range dependent traffic ... -
Type-2 fuzzy entropy-sets
The final goal of this study is to adapt the concept of fuzzy entropy of De Luca and Termini to deal with Type-2 Fuzzy Sets. We denote this concept Type-2 Fuzzy Entropy-Set. However, the construction of the notion of ... -
Unbalanced interval-valued OWA operators
In this work, we introduce a new class of functions defned on the interval-valued setting. These functions extend classical OWA operators but allow for diferent weighting vectors to handle the lower bounds and the ... -
Use of CBR for IP over ATM
Internet traffic burstiness allows for statistical multiplexing gain in the available bandwidth of an ATM link. However, a dynamic allocation bandwidth assignment (ABR) has to be performed. In this paper we evaluate the ... -
The use of two relations in L-fuzzy contexts
In the analysis of relations among the elements of two sets it is usual to obtain different values depending on the point of view from which these relations are measured. The main goal of the paper is the modelization of ...
