This paper describes the development of small mobile robots for collaborative surveillance tasks. Each of the robots, called Millibots, has only limited sensing, computation, and communication capabilities. However, by collaborating with other robots, they can still perform useful tasks. The task that we are considering is collaborative mapping and exploration inside buildings. To guarantee acc...

BACKGROUND With the widespread availability of non-invasive imaging of the brain in an aging population, we are increasingly confronted with the problem of the incidental discovery of unruptured aneurysms. The management of these patients remains controversial. Endovascular treatment can prevent rupture, but involves immediate risks. Furthermore, successful treatment does not eliminate all risk...

Pseudoaneurysms of the superficial temporal artery are rare and may be treated by manual compression, surgical intervention, coil embolization, or percutaneous thrombin injection. We present a novel technique of local ultrasound guided low-profile coil embolization of the superficial temporal artery with both satisfactory cosmetic and surgical results.

The computer world is experiencing a paradigm shift towards context-aware pervasive computing, where diverse computer devices communicate with each other through different network access technologies, and allow resource access based on user preferences. P2P computing is an area which will be affected by this new trend. In this paper, we proposed a resource replication strategy for context-aware...

Beyond 3G usually refers to heterogeneous scenarios where different Radio Access Technologies (RATs) coexist and operate in a coordinated way. This brings a new challenge to offer services to the users over an efficient and ubiquitous radio access. In this way, the user can be served through the RAT that fits better to the terminal capabilities and service requirements, and also a more efficien...

The future of mobile telecommunications is aimed at creating a usercentric wireless world which takes into account user’s preferences, as well as communication context (e.g., network and terminal heterogeneity or user location). In order to enable context-aware personalization of communication services offered by next-generation mobile networks, we propose an agentbased approach in combination ...

The aim of this study was to determine the effect of knowledge management capabilities and information technology capabilities on innovative performance with the mediating role of organizational entrepreneurship, organizational learning and competitive advantage. The research method is descriptive-survey. The statistical population consists of all employees of Shimifar Iran Company, and 137 peo...

The most popular algorithms for the estimation of the probabilities of a context-free grammar are the Inside-Outside algorithm and the Viterbi algorithm, which are Maximum Likelihood approaches. The diierence between the logarithm of the likelihood of a string and the logarithm of the likelihood of the most probable parse of a string is upper bounded linearly by the length of the string and the...

ECLAC’s policy prescriptions seems even less tenable. After all, this was a region that for most of the 1990s was firmly in the neoliberal camp. More importantly, even to the extent that leftist presidents (such as Lula in Brazil) came to power, their ability to change the status quo was fairly limited. While the author is keen to blame these failures on the intellectual retreats of neostructur...
