With the growing academic and industrial interest in Software Product Lines (SPL), one area demanding special attention is tool support development, which is a pre-requisite for widespread SPL practices adoption. In this paper, we present FLiPEx, a code refactoring tool that can be used for extraction of product variations in the context of developing mobile game SPLs.

In EuroSpeech’95, we presented the first version of Sethos, the speech understanding system which has been developed at the UPC. In this paper some improvements are incorporated at different levels of Sethos: language model, models of the semantic units and acoustic models. These improvements increase the percentage of correctly decoded sentences from 60% to 80%. Some experiments are presented ...

In this paper, we describe the UPC systems that participated in the TweetMT shared task. We developed two main systems that were applied to the Spanish–Catalan language pair: a state-of-the-art phrase-based statistical machine translation system and a context-aware system. In the second approach, we define the “context” for a tweet as the tweets of a user produced in the same day, and also, we ...

Rückverfolgbarkeit von Lebensmitteln ist in der EU eine gesetzliche Anforderung, für die RFID/EPC eine technische Alternative darstellt. In diesem Beitrag diskutieren wir ökonomische Faktoren, die die Adoption von RFID/EPC zum Zweck der Rückverfolgbarkeit beeinflussen können. Die Diskussion erfolgt aus der Perspektive von integrierten Rückverfolgungssystemen, bei denen die Unternehmen einer Anb...

Mean shape-gain vector quantization (MSGVQ) is extended to include negative gains and square isometries. Square isometries together with a classi cation technique based on average block intensities enable us to enlarge the MSGVQ codebook size without any additional storage requirements while keeping the complexity of both the codebook generation and the encoding manageable. Variable rate codes ...

Modular product design has received great attention for about 10 years but few works have proposed tools to either jointly design the functional and physical architectures or propagate the impact of evolutions from one domain to another. In this paper we present a new method supporting the product architecture design. In new product development situations or in reengineering projects, system ar...

New reconfigurable computing crossbar architecture based on memFETs has been developed and patented. This breakthrough technology, developed by a group of scientist from UAB and UPC represents an alternative to conventional computational systems as it adapts the size and composition dynamically, without any changes in CMOS manufacturing process required. Partners to further develop the system a...

This paper presents a novel approach to speaker orientation estimation in a SmartRoom environment equipped with multiple microphones. The ratio between the high and low band energies (HLBR) received at each microphone has been shown in our previous work to be a potentially approach to estimate the direction of the voice produced by a speaker. In this work, for each microphone pair, a smoothed C...

PURPOSE Surveys of patients' experiences typically show results that are indicative of positive experiences. Unbalanced response scales have reduced positive skew for responses to items within the Universal Patient Centeredness Questionnaire (UPC-Q). The objective of this study was to compare the unbalanced response scale with another unbalanced approach to scaling to assess whether the positiv...

If two or more code fragments in the code-base of a software system are exactly or nearly similar to one another, we call them code clones. It is often important that updates (i.e., changes) in one clone fragment should be propagated to the other similar clone fragments to ensure consistency. However, if there is a delay in this propagation because of unawareness, the system might behave incons...
