Development of a data acquisition system to characterise sustainable energy technologies and to support Web-Based learning (DAQ-WBL)

Driven by concerns about rising energy costs, security of supply and climate change a new wave of Sustainable Energy Technologies (SET’s) have been embraced by the Irish consumer. Such systems as solar collectors, heat pumps and biomass boilers have become common due to government backed financial incentives and revisions of the building regulations. However, there is a deficit of knowledge and understanding of how these technologies operate and perform under Ireland’s maritime climate. This AQ-WBL project was designed to address both these needs by developing a Data Acquisition (DAQ) system to monitor the performance of such technologies and a web-based learning environment to disseminate performance characteristics and supplementary information about these systems. A DAQ system consisting of 108 sensors was developed as part of Galway-Mayo Institute of Technology’s (GMIT’s) Centre for the Integration of Sustainable EnergyTechnologies (CiSET) in an effort to benchmark the performance of solar thermal collectors and Ground Source Heat Pumps (GSHP’s) under Irish maritime climate, research new methods of integrating these systems within the built environment and raise awareness of SET’s. It has operated reliably for over 2 years and has acquired over 25 million data points. Raising awareness of these SET’s is carried out through the dissemination of the performance data through an online learning environment. A learning environment was created to provide different user groups with a basic understanding of a SET’s with the support of performance data, through a novel 5 step learning process and two examples were developed for the solar thermal collectors and the weather station which can be viewed at http://www.kdp 1 .aquaculture.ie/index.aspx. This online learning environment has been demonstrated to and well received by different groups of GMIT’s undergraduate students and plans have been made to develop it further to support education, awareness, research and regional development.

Obesity Resistance Promotes Mild Contractile Dysfunction Associated with Intracellular Ca2+ Handling

Abstract Background: Diet-induced obesity is frequently used to demonstrate cardiac dysfunction. However, some rats, like humans, are susceptible to developing an obesity phenotype, whereas others are resistant to that. Objective: To evaluate the association between obesity resistance and cardiac function, and the impact of obesity resistance on calcium handling. Methods: Thirty-day-old male Wistar rats were distributed into two groups, each with 54 animals: control (C; standard diet) and obese (four palatable high-fat diets) for 15 weeks. After the experimental protocol, rats consuming the high-fat diets were classified according to the adiposity index and subdivided into obesity-prone (OP) and obesity-resistant (OR). Nutritional profile, comorbidities, and cardiac remodeling were evaluated. Cardiac function was assessed by papillary muscle evaluation at baseline and after inotropic maneuvers. Results: The high-fat diets promoted increase in body fat and adiposity index in OP rats compared with C and OR rats. Glucose, lipid, and blood pressure profiles remained unchanged in OR rats. In addition, the total heart weight and the weight of the left and right ventricles in OR rats were lower than those in OP rats, but similar to those in C rats. Baseline cardiac muscle data were similar in all rats, but myocardial responsiveness to a post-rest contraction stimulus was compromised in OP and OR rats compared with C rats. Conclusion: Obesity resistance promoted specific changes in the contraction phase without changes in the relaxation phase. This mild abnormality may be related to intracellular Ca2+ handling.

Implementation of a unified userspace time handling library under the Linux OS

An appropriate assessment of end-to-end network performance presumes highly efficient time tracking and measurement with precise time control of the stopping and resuming of program operation. In this paper, a novel approach to solving the problems of highly efficient and precise time measurements on PC-platforms and on ARM-architectures is proposed. A new unified High Performance Timer and a corresponding software library offer a unified interface to the known time counters and automatically identify the fastest and most reliable time source, available in the user space of a computing system. The research is focused on developing an approach of unified time acquisition from the PC hardware and accordingly substituting the common way of getting the time value through Linux system calls. The presented approach provides a much faster means of obtaining the time values with a nanosecond precision than by using conventional means. Moreover, it is capable of handling the sequential time value, precise sleep functions and process resuming. This ability means the reduction of wasting computer resources during the execution of a sleeping process from 100% (busy-wait) to 1-1.5%, whereas the benefits of very accurate process resuming times on long waits are maintained.

L'accés als recursos web des de les biblioteques

L’objecte central del present informe és descriure l’estat de la qüestió –tant a Catalunya com a altres països– de l’accés als recursos web des de les biblioteques. De fet, l’objectiu últim és presentar i analitzar la situació a l’estranger per tal d’adaptar les estratègies i els models de tractament i organització de recursos web a la realitat i les necessitats de les biblioteques catalanes.

Portal web per a l'IES Pla d'en Boet de Mataró

Aquesta memòria tracta sobre el procediment de creació software que s’ha dut a terme per a implementar el portal web de l’IES Pla d’En Boet de Mataró, un institut públic subvencionat per la Generalitat de Catalunya. Aquest portal s’ha desenvolupat des de zero i s’ha hagut d’enllaçar amb altres aplicacions que han sigut requerides. El document conté l’anàlisi, disseny i l’implementació del portal web, i de tota la funcionalitat que l’envolta, que s’ha realitzat per satisfer els requeriments inicials. Conté, a més, les diferents anàlisis que s’han necessitat per tal d’integrar-lo amb una aplicació pròpia del centre i amb un sistema d’intercanvi de missatges, i com s’ha decidit fer-ho. S’intenta explicar alguna de les problemàtiques més importants que han aparegut al llarg del procés i que han afectat al seu desenvolupament. Les decisions preses per a resoldre-les també apareixen per avalar l’estudi realitzat. Finalment hi ha una valoració personal i una altra dels objectius aconseguits per veure que s’ha arribat a la solució final amb èxit.

Disseny i implementació d'un web modular amb gestió de continguts

Aquest projecte té com a objectiu el desenvolupament d'un site web amb la possibilitat que la gestió del seu contingut fos administrat per persones alienes a la implementació de la web. Aquesta fita ha estat duta a terme en una web d'una entitat esportiva, la Unió Esportiva Sant Cugat, des d'on durant 2 anys i mig s'ha gestionat la informació i comunicació a través de la xarxa amb aquest mitjà. L'estructuració del projecte ha estat totalment modular, per d'aquesta manera facilitar el dinamisme de canvis de possibles continguts que es poden incorporar a la web de manera molt ràpida i senzilla.
