In this paper, we present an automatic tag suggester, Tess. Our system makes recommendations based only on the textual contents of the resource and is independent of existing tags, thus allowing the emergence of novel tags. Preliminary evaluation experiments show that the system is not only able to suggest many useful tags, but also to discover new and relevant tags, not suggested by any of the...

Hemifacial microsomia is a rare congenital malformation of craniofacial structures. Its characteristic features are unilateral underdevelopment of the face and ear malformations. This study describes clinical and radiographical features of a rare case of a 4-year-old hemifacial microsomia patient with underdevelopment of the left side of the face and preauricular skin tags on the affected side...

After six decades of studying radio galaxies, we are now delightfully overwhelmed by their exponentially expanding numbers and the complexity structures. Similarly, methods use to classify galaxies have exploded, often resulting in conflicting terminology, ambiguous classifications, historical schemes that may or not match our current physical understanding. discussions with more than 100 astro...

In 2004, Molnar and Wagner introduced a very appealing scheme dedicated to the identification of RFID tags. Their protocol relies on a binary tree of secrets which are shared – for all nodes except the leaves – amongst the tags. Hence the compromise of one tag also has implications on the other tags with whom it shares keys. We describe a new man-in-the-middle attack against this protocol which...

We consider the median estimation problem in a large-scale sensor augmented RFID system. The large-scale deployment of RFID technology has opened the door to innovative ways to integrate RFID and sensor technology. Sensor-tags are tags that can report over 50 types of physical information to a reader. The traditional way to obtain information from sensor-tags is to query each tag. When the numb...

Computation RFID (CRFID) expands the limit of traditional RFID by granting computational capability to RFID tags. RFID tags are powered by Radio-Frequency (RF) energy harvesting. However, CRFID tags need extra energy and processing time than traditional RFID tags to sense the environment and generate sensing data. Therefore, Dynamic Framed Slotted ALOHA (DFSA) protocol for traditional RFID is n...

Social tags are user-generated keywords associated with some resource on the Web. In the case of music, social tags have become an important component of “Web2.0” recommender systems, allowing users to generate playlists based on use-dependent terms such as chill or jogging that have been applied to particular songs. In this paper, we propose a method for predicting these social tags directly f...
