Desarrollo de un índice espacial para la extensión JASPA sobre H2

El presente trabajo tiene por objetivo ofrecer una solución para la creación de un índice espacial para la extensión JASPA (Java SPAtial) sobre la base de datos H2. El algoritmo de indexación elegido para la implementación del índice espacial ha sido el Rtree.La implementación se ha realizado con el lenguaje de programación Java lo que ha facilitado su integración con la extensión JASPA y la base de datos H2, dado que ambos proyectos están codificados en el mismo lenguaje. El índice es persistente en memoria secundaria en una tabla de la propia base de datos H2.La solución que se propone está limitada a operaciones espaciales en dos dimensiones y es lo suficientemente flexible como para que no se haya necesitado modificar ni el código fuente de JASPA, ni de H2. Además, se ha previsto que el algoritmo de indexación se pueda mejorar o sustituir fácilmente.Por último, se ha tenido en cuenta que el proceso de creación y manipulación de los índices espaciales sea intuitivo y fácil de usar.

Implementació d’un sistema xat multiprotocol fent servir el llenguatge de programació ERLANG

Construcció d’una aplicació amb un llenguatge de programació concurrent i distribuït anomenat Erlang. Erlang és un llenguatge de programació funcional amb avaluació estricta, és a dir, assignació única i que inclou una màquina virtual. L’aplicació desenvolupada ha estat la programació d’un xat multiprotocol, el qual s’ha realitzat una primera part que ha consistit en el construcció d’un servidor per la xarxa local i el seu corresponent client. Llavors per poder fer un client més funcional i útil s’ha implementat un altre protocol, IRC. Al tractar-se d’un llenguatge espacialment dissenyat per treballar en processos s’ha intentat dissenyar d’una manera la qual es pugés aprofitar aquesta qualitat

Mise en place d'un cathéter veineux central chez l'adulte. 2. Technique détaillée [The central vein catheterization. 2. Procedure, step by step]

La pose d'un cathéter veineux central peut se faire par plusieurs abords. La connaissance de l'anatomie, du matériel, la maîtrise des détails de la procédure pour chaque type d'abord et une attention particulière à l'asepsie sont des prérequis importants pour limiter les risques de complications et pour donner une information complète et exhaustive au patient. Cet article peut être utilisé comme base pour le développement d'une check-list, utile pour les médecins qui doivent procéder à la pose d'un cathéter veineux central mais qui ne possèdent pas encore une maîtrise du geste. Several approaches exist for central vein catheterization. Mastery of the various steps of this procedure and understanding of the basics of asepsis are critical to prevent any complication. They also built the basis for an exhaustive communication with the patient, to obtain an informed consent. This article can in addition be used to develop a checklist in order to (self-)assess competence in procedural skills

Network revenue management with product-specific no-shows

Revenue management practices often include overbooking capacity to account for customerswho make reservations but do not show up. In this paper, we consider the network revenuemanagement problem with no-shows and overbooking, where the show-up probabilities are specificto each product. No-show rates differ significantly by product (for instance, each itinerary andfare combination for an airline) as sale restrictions and the demand characteristics vary byproduct. However, models that consider no-show rates by each individual product are difficultto handle as the state-space in dynamic programming formulations (or the variable space inapproximations) increases significantly. In this paper, we propose a randomized linear program tojointly make the capacity control and overbooking decisions with product-specific no-shows. Weestablish that our formulation gives an upper bound on the optimal expected total profit andour upper bound is tighter than a deterministic linear programming upper bound that appearsin the existing literature. Furthermore, we show that our upper bound is asymptotically tightin a regime where the leg capacities and the expected demand is scaled linearly with the samerate. We also describe how the randomized linear program can be used to obtain a bid price controlpolicy. Computational experiments indicate that our approach is quite fast, able to scale to industrialproblems and can provide significant improvements over standard benchmarks.

Translating from India and the Moving Space of Translation (Illustrated by the Works of Ajñeya)

The inadequacies and obsolescence of Eurocentric theories based on a binaryand static worldview have become a staple topic of postcolonial studies, and tosome extent also of translation studies. Nonetheless, the literary texts that arecalled upon in order to show the dynamism and hybridity of (post)modern worksbelong for the most part to the languages of the former colonial powers, especiallyEnglish, and remain inserted in a system that construes literatures interms of opposition. As a consequence, there is outside India a doubly misleadingunderstanding of Indian literatures other than those written in English:firstly, that translations of works in Hindi and in the Indian bhāṣā seem to belacking, if not inexistent, and secondly, that these "minor" literatures - as theyare regularly termed - are still often viewed as being highly dependent on theidea of "tradition," in opposition to the "postmodern" hybridity of the literatureswritten in the "dominant" languages, such as English or French. Againstthese views and supported by the analysis of Ajñeya's works in Hindi togetherwith their English translations, this paper aims to show: 1) that translationsfrom Hindi, which are not in fact non-existent, are mainly carried out in India,and 2) that Ajñeya's works, while representing a significant instance of the effectivehybridity present in Indian literatures, help to illustrate the moving spaceof translation. This demonstration effectively invalidates the above-mentionedoppositional standpoint.

Science, practice and patient needs: the work of the Plinius Maior Society.

The Plinius Maior Society is a European multinational, multidisciplinary group of clinicians and researchers in the alcoholism field, which strives for a comprehensive care concept in the management of alcoholism and alcohol-related problems. The Society, using evidence-based medicine, has developed a set of protocols, in the forms of guidelines, flow-charts, leaflets and booklets, for use as tools in research on and treatment of alcohol dependence, with a view to standardize clinical research procedures and to bridge the gap between the alcoholism researcher, practitioner and patient. These protocols or tools have been subjected to a review process during their preparation, and further comments on their validity will be integrated in their updates. Seven protocols have so far been developed, two of which, 'Guidelines on Evaluation of Treatment of Alcohol Dependence' and 'Detection and Management of Patients with Psychiatric and Alcohol Use Disorders', are aimed at the clinical researcher and specialists, whereas three others [in the form of decision trees (flow-charts)] are aimed at the general practitioner and other primary health care providers. These are entitled 'Alcohol Risk Assessment and Intervention in Primary Care', 'Withdrawal from Alcohol at Home' and 'Brief Intervention in Patients with Alcohol-Related Problems'. The remaining two tools are booklets aimed at the patient, one to support initiatives for detection of drinking problems and primary intervention, namely 'Do you have this Problem? Discuss it with your Doctor!', and the other to assist the patient in relapse prevention after the early stages of treatment, namely 'On the Way to Recovery'. The protocols for the general practitioners and patients have so far been produced in seven European languages, and, as with the Guidelines, feedback from target users will be collected and incorporated in future updates. The Society continually seeks to consider areas of clinical importance for its work and, as it enters the new millennium, it hopes to address and make a significant contribution to the most pressing problem in the management of alcohol dependence, namely relapse.

Telementoring during endovascular treatment of abdominal aortic aneurysms: a prospective study.

PURPOSE: To explore the use of telementoring for distant teaching and training in endovascular aortic aneurysm repair (EVAR). METHODS: According to a prospectively designed study protocol, 48 patients underwent EVAR: the first 12 patients (group A) were treated at a secondary care center by an experienced interventionist, who was training the local team; a further 12 patients (group B) were operated by the local team at their secondary center with telementoring by the experienced operator from an adjacent suite; and the last 24 patients (group C) were operated by the local team with remote telementoring support from the experienced interventionist at a tertiary care center. Telementoring was performed using 3 video sources; images were transmitted using 4 ISDN lines. EVAR was performed using intravascular ultrasound and simultaneous fluoroscopy to obtain road mapping of the abdominal aorta and its branches, as well as for identifying the origins of the renal arteries, assessing the aortic neck, and monitoring the attachment of the stent-graft proximally and distally. RESULTS: Average duration of telementoring was 2.1 hours during the first 12 patients (group B) and 1.2 hours for the remaining 24 patients (group C). There was no difference in procedural duration (127+/-59 minutes in group A, 120+/-4 minutes in group B, and 119+/-39 minutes in group C; p=0.94) or the mean time spent in the ICU (26+/-15 hours in group A, 22+/-2 hours in group B, and 22+/-11 hours for group C; p=0.95). The length of hospital stay (11+/-4 days in group A, 9+/-4 days in group B, and 7+/-1 days in group C; p=0.002) was significantly different only for group C versus A (p=0.002). Only 1 (8.3%) patient (in group A: EVAR performed by the experienced operator) required conversion to open surgery because of iliac artery rupture. This was the only conversion (and the only death) in the entire study group (1/12 in group A versus 0/36 in groups B + C, p=0.31). CONCLUSIONS: Telementoring for EVAR is feasible and shows promising results. It may serve as a model for development of similar projects for teaching other invasive procedures in cardiovascular medicine.

Kiinteistön ohjaus- ja valvontajärjestelmän toteutus mobiiliympäristöön

Ohjelmistoprojektin läpivienti vaatii suunnittelua ja yhteisiä tapaamisia toimittajan ja asiakkaan kesken. Ohjelmistotuotannon prosessit ovat määrittely, suunnittelu, toteutus, testaus ja käyttöönotto. Tärkeimmät dokumentit ovat projektisuunnitelma, toiminnallinen määrittely ja tekninen määrittely. Ongelmia projektin läpiviennissä voi tulla silloin, jos toimittaja ja asiakas eivät ymmärrä toisiaan. Tässä työssä tehdään SMSviestejä käsittelevä mobiilisovellus ja siihen liittyvät projektisuunnitelma sekä määrittelydokumentit. Mobiilisovellus ohjelmoidaan J2ME:llä, joka on sulautettujen järjestelmien ohjelmointiin suunniteltu Java-kieli. Sovellus tukee toisen asteen opiskelijoille suunnattuja mobiiliohjelmointi opintoja. Opintojakso kuuluu Pohjois- Karjalan ammattiopiston järjestämään turvallisuusalan koulutukseen. Sovelluksella voidaan lähettää ohjausviestejä OUMAN EH-60 -ohjaus- ja valvontayksikköön. Yksikön avulla voi ohjata ja valvoa esimerkiksi kiinteistön lämmönsäätöä, vesivahinkoja, oven lukitusta jne. Tässä työssä tehtävällä sovelluksella demonstroidaan kesämökin ohjausta. Langaton tiedonsiirto tulee tulevaisuudessa lisääntymään kiinteistöjen ohjaus- ja valvontajärjestelmänä. Hätä- ja valvontaviestit lähetetään automaattisesti kiinteistön omistajalle, hoivapalveluyrittäjälle, talohuoltoon tai hätäkeskukseen. Kiinteistön omistaja voi omalla matkapuhelimellaan ajasta ja paikasta riippumattavalvoa ja ohjata kiinteistöään reaaliaikaisesti. Pohjois-Karjalan ammattiopisto haluaa olla kehittämässä ja toteuttamassa turvallisuusalan koulutusta nyt ja tulevaisuudessa.
