— The available bandwidth (AB) of an end-to-end path is its remaining capacity and it is an important metric for several applications. That´s why several available bandwidth estimation tools have been published recently. Most of these tools use the Probe Rate Model. This model is based on the concept of self-induced congestion and requires that the tools(More)
— In the context of the Web, an ontology provides a shared insight of a certain domain. It basically represents a knowledge base with interrelated concepts called classes. Relationships among classes in an OWL ontology are given by the object properties that are defined as a binary relation between classes in the domain with classes in the range. From a(More)
—WiFi fingerprinting has received much attention for indoor mobile phone localization. In this study, we examine the impact of various aspects underlying a WiFi fingerprinting system. Specifically, we investigate different definitions for fingerprinting and location estimation algorithms across different indoor environments ranging from a multi-storey(More)
—We present a mobile crowdsensing approach for urban WiFi characterization that leverages commodity smart-phones and the natural mobility of people. Specifically, we report measurement results obtained for Edinburgh, a representative European city, on detecting the presence of deployed WiFi APs via the mobile crowdsensing approach. They show that few(More)
Protein ubiquitination is a highly versatile post-translational modification that regulates as diverse processes as protein degradation and kinase activation. Deubiquitinases hydrolyse ubiquitin modifications from proteins and are hence key regulators of the ubiquitin system. Ovarian tumour deubiquitinases comprise a family of fourteen human enzymes, many(More)
BACKGROUND Cancer chemoprevention is a new approach in cancer prevention, in which chemical agents are used to prevent cancer in normal and/or high-risk populations. Although chemoprevention has shown promise in some epithelial cancers, currently available preventive agents are limited and the agents are costly, generally with side effects. Natural(More)
BACKGROUND In a recent pilot report, we showed that Smac/DIABLO mRNA is expressed de novo in a subset of cervical cancer patients. We have now expanded this study and analyzed Smac/DIABLO expression in the primary lesions in 109 cervical cancer patients. METHODS We used immunohistochemistry of formalin-fixed, paraffin-embedded tissue sections to analyze(More)
—With ever growing data traffic the traditional mobile network architecture is struggling to cope. Network densification using heterogeneous networks supported by Cloud-RAN is one of the core concepts in terms of physical resources. The system achieves increased capacity by reducing the number of devices (commonly refered to as user equipment-UE) connected(More)
In this paper we describe a proposal to define adaptive rules that adjust learning designs to learner's knowledge and learning styles, using a collection of sets based mostly on the IMS Learning Design (IMS LD) specification. Authors will use this collection to define adaptive statements, which also could be used to define adaptive techniques and students(More)
—We study coexistence interference that arises between multiple collocated radio interfaces on 802.11 based multi-radio platforms used for mesh networks. We show that such interference can be so severe that it prevents concurrent successful operation of collocated interfaces even when they use channels from widely different frequency bands. We propose the(More)
