A Portable Dynamic Laser Speckle System for Sensing Long-Term Changes Caused by Treatments in Painting Conservation
2018
[EN] Dynamic laser speckle (DLS) is used as a reliable sensor of activity for all types of materials. Traditional applications are based on high-rate captures (usually greater than 10 frames-per-second, fps). Even for drying processes in conservation treatments, where there is a high level of activity in the first moments after the application and slower activity after some minutes or hours, the process is based on the acquisition of images at a time rate that is the same in moments of high and low activity. In this work, we present an alternative approach to track the drying process of protective layers and other painting conservation processes that take a long time to reduce their levels …
On the impact of within-die process variation in GALS-Based NoC Performance
2012
[EN] Current integration scales allow designing chip multiprocessors (CMP), where cores are interconnected by means of a network-on-chip (NoC). Unfortunately, the small feature size of current integration scales causes some unpredictability in manufactured devices because of process variation. In NoCs, variability may affect links and routers causing them not to match the parameters established at design time. In this paper, we first analyze the way that manufacturing deviations affect the components of a NoC by applying a new comprehensive and detailed within-die variability model to 200 instances of an 8¿8 mesh NoC synthesized using 45 nm technology. Later, we show that GALS-based NoCs pr…
Cost-Efficient On-Chip Routing Implementations for CMP and MPSoC Systems
2011
[EN] The high-performance computing domain is enriching with the inclusion of networks-on-chip (NoCs) as a key component of many-core (CMPs or MPSoCs) architectures. NoCs face the communication scalability challenge while meeting tight power, area, and latency constraints. Designers must address new challenges that were not present before. Defective components, the enhancement of application-level parallelism, or power-aware techniques may break topology regularity, thus, efficient routing becomes a challenge. This paper presents universal logic-based distributed routing (uLBDR), an efficient logic-based mechanism that adapts to any irregular topology derived from 2-D meshes, instead of usi…
Health Education at La Ribera Universitary Hospital
2013
This paper describes the potential of learning platforms offering at the La Ribera Health Department. More than 100 activities have been designed and at least 5000 users have been participating. The paper concludes, first, that there are important factors to achieve a successful implementation of such elearning project. In second place it remarks that elearning platform can be used for other support activities rather than only online courses. Finally, the study emphasizes that training in electronic medical record of our professionals is a key element of hospital business.
Age slowing down in detection and visual discrimination under varying presentation times
2017
[EN] The reaction time has been described as a measure of perception, decision making, and other cognitive processes. The aim of this work is to examine agerelated changes in executive functions in terms of demand load under varying presentation times. Two tasks were employed where a signal detection and a discrimination task were performed by young and older university students. Furthermore, a characterization of the response time distribution by an exGaussian fit was carried out. The results indicated that the older participants were slower than the younger ones in signal detection and discrimination. Moreover, the differences between both processes for the older participants were higher,…
E-Learning Experiences in La Ribera Health Department
2014
This paper shows how the training of health professionals is improving thanks to the use of new technologies, in particular e-learning. This type of technology is widely used in medical education and there are multiple research works that report its effective deployment by health professionals and students. However, there is a need to incorporate e-learning platforms and online methods in healthcare organizations through a systematic and rigorous approach what is proposed in the current work. This approach has been applied since 2009 in the context of La Ribera Health Department implementing a high number of e-learning experiences. The obtained outcomes reveal how useful have been these exp…
