To tame the complexity of engineering customizable software, systems are built as families of products that share a common core. As customers desire the automatic and smart adjusting of their software to various contexts of operation, runtime reconfiguration capabilities need to be added. In this extended abstract, we sketch reengineering challenges to be tackled when evolving classic software ...

In 2006 EPCglobal and the International Organization for Standards (ISO) ratified the EPC Class-1 Generation-2 (Gen-2) [1] and the ISO 18000-6C standards [2], respectively. These efforts represented major advancements in the direction of universal standardization for low-cost RFID tags. However, a cause for concern is that security issues do not seem to be properly addressed. In this paper, we ...

This paper aims at quantitatively assessing the impact of radio frequency identification (RFID) technology and electronic product code (EPC) system on the main processes of the fashion industry supply chain. A fashion supply chain, composed of a distribution centre (DC) and a retail store (RS), is examined. A questionnaire survey and several site visits were performed to collect both quantitati...

Wireless local area networks (WLANs) are commonplace in many universities. Understanding the trends in the usage of these networks is becoming more important. Interesting results can be extracted about association patterns by analyzing WLAN traces from real scenarios. In this work, the library in the main campus of the Technical University of Catalonia (UPC) in Barcelona has been studied. Daily...

Today, software product line engineering concentrates on tailoring the functionality of programs. However, we and others observed an increasing interest in non-functional properties of products. For example, performance, power awareness, maintainability, and resource consumption are important nonfunctional properties in software development. Current product line techniques have the potential to...

This paper describes different aspects of a typical RFID implementation. Section 1 provides a brief overview of the concept of Automatic Identification and compares the use of different technologies while Section 2 describes the basic components of a typical RFID system. Section 3 and Section 4 deal with the detailed specifications of RFID transponders and RFID interrogators respectively. Secti...

In many countries that use the “inventive step” test for patentability, the term “inventive step” is specifically defined to refer to something that is “not o...

This paper presents the results of the UPC-UB-STP team in the 2015 MediaEval Retrieving Diverse Images Task. The goal of the challenge is to provide a ranked list of Flickr photos for a predefined set of queries. Our approach firstly generates a ranking of images based on a query-independent estimation of its relevance. Only top results are kept and iteratively re-ranked based on their intra-si...
