The Initium RJS Screensaver: Part 4, Automatic Deployment

The Intium RJS System makes use of screensavers to perform CPU scavenging for grid computing. A Java Web Start application has been created to complete the installation of the screensaver for Windows and Unix/Linux platform. This application identifies the operating system and proceeds to download, install, and configure the screensaver files

The Initium RJS Screensaver: Part 1, MS Windows

We are interested in screen-saver technologies, in Java, in order to facilitate a minimally invasive computing service able to make use of otherwise unused computational resources. There is little written on the subject of screen-saver based grid computing, in Java

The Saverbeans Screensaver and Initium RJS System Integration: Part 5

We describe the process followed to integrate the IRJS screensaver with the IRJS grid computing middleware. Our goal is to provide a minimally invasive CPU scavenging technology. The IRJS screensaver launches a Compute Server (CS) when the computer enters a quiescent state. The CS joins the grid and volunteers its resources. The IRJS screensaver terminates the CS when any user input is detected. We use the [Saverbeans] framework to create our screensaver and to allow such behavior

The Initium RJS ScreenSaver: Part 2, UNIX

We are motivated to study screen-savers because they represent a minimally invasive technology for volunteering CPU services. Typically, computers are used between 40 and 60 hours out of a 168-hour week. This represents approximately 35% utilization. Our theory is that a screen-saver based cycle scavenging will improve this number dramatically

Discrete simulations of model, loose cohesive powders: plastic consolidation, fractal microstructure and tensile strength

4 pagesInternational audienceIsotropic packings of cohesive disks in 2D are studied by discrete, stress-controlled numerical simulations. Depending on the assembling process and on whether contacts possess rolling resistance (RR), configurations form under low pressure $P$ with varying solid fraction $\Phi$ and fractal dimension $d_F$ describing small scale correlations below some blob size $\xi$. The gradual collapse observed under growing $P$ is described as a linear relation between $\ln P$ and $1/\Phi$ within some range, once the influence of initial conditions has faded out, and until a maximum density is approached. This corresponds to a decrease of $\xi$ that is compatible with the fractal blob model. The isotropic tensile strength is always considerably smaller than the naive Rumpf estimate, and grows with consolidation. Coordination numbers in systems with small RR change little while density increases by large amounts in consolidation

Computer simulation of model cohesive powders: influence of assembling procedure and contact laws on low consolidation states.

31 pages Only 26 pages in the published PRE paper, but figures look better in THIS version !International audienceThe structure and mechanical properties of a simple two-dimensional model of a cohesive powder are investigated by molecular dynamics simulations. Micromechanical ingredients involve elasticity, friction, a short range attraction and, possibly, rolling resistance (RR) in contacts. The microstructure of the cohesive packing varies according to the assembling procedure, from rather densely packed if isolated particles are directly compressed to much looser if the formation of large aggregates is allowed prior to compression. A crucial parameter is the ratio P*= Pa/F0 of applied pressure P, acting on grains of diameter $a$, to maximum tensile contact force F0. At low P* the final structure depends on the level of velocity fluctuations at the early stages of cluster aggregation. With RR the coordination number approaches 2 in the limit of low initial velocities or large rolling friction. The force network generally comprises small hyperstatic clusters with forces of the order of F0, joined by nearly unstressed, barely rigid arms. As P* grows, it quickly rearranges into force chain-like patterns. Density correlations witness a fractal structure, with dimension Df, up to some density-dependent blob size. WIth RR Df coincides with the ballistic aggregation result, despite a possibly different connectivity. Possible effects of some parameters on material strength are evoked

Phase equilibria and P-T-X (Fe-Mg) relations involving GT-St-Cd-Als-Bi-Mu-Qz-Kfs-H20 in medium-high grade metapelites (KFASH,KMASH and KFMASH systems)

En rocas metapelíticas de diversas áreas en el Hercínico de la Península Ibérica se observan a menudo las siguientes reacciones: Estaurolita + moscovita + cuarzo = biotita + Al2SiO5+ H2O Granate + moscovita = Al2SiO5 + biotita ± cuarzo Biotita + Al2SiO5 + cuarzo = cordierita + feldespato potásico + H2O. Se han estudiado en el sistema con K2O -FeO- Al2O3-SiO2-H2O (KFASH) tres asociacioness con Bi-Mu-St-Als-Qz- H2O además de Cd-Gt-Fk, eliminando en cada una de ellas una de las tres últimas fases. La expansión de las reacciones que se obtienen con estas asociaciones, en superficies divariantes a través del espacio P-T-X(Fe-Mg), se realizó estudiando la asociación GtSt- Cd-Bi-Mu-Fk-Als-Qz- H2 en el sistema KFMASH con una relación Fe/Fe+Mg según Gt St Bi Cd, tal como se observa en la mayoría de roca pelíticas. A partir de las anteriores redes se ba obtenido otra para condiciones de PH20=Pt baja fugacidad de oxígeno (tampón QFM), y exceso de moscovita y cuarzo. Las pendientes de las reacciones en esta última red se calcularon para diferentes condiciones poTo Se han obtenido las relaciones teóricas P-T-X(Fe-Mg) para tres reacciones univariantes y trece divariantes. La red confirma la imposibilidad de la coexistencia entre estaurolita y feldespato potásico y entre granate, cordierita y moscovita. Se constata, además, la extensión de los campos de estabilidad de Gt-St, Cd-St y Gt-Cd en metapelitas pobres en moscovita.In different areas of the Hercynian in the Iberian Peninsula sorne reactions are repeatedly observed in pelites, these reactions are: Staurolite + muscovite + quartz = Biotite+ Al2SiOs+ H20 Garnet + muscovite = AI2SiOs+ biotite+ quartz Biotite + Al2SiOs + quartz = Cordierite + K feldspar+Hp In order to examinate the P-T stability fields of tbese, and otber similar reactions, aH the univariant equilibria in multisystems with Gt-Cd-St-Bi-Mu-Als-Qz-HP, Gt-St-Bi-Mu-Fk-AIs-QzHp and Cd-St-Bi-Mu-Fk-AIs-Qz-H20 in Kp-FeO-AI20 r Si02-H20 (KFASH) system have been calculated, and their corresponding P-T grids have been constructed. The expansion of these reactions into divariant surfaces through the P-T-X (Fe-Mg) space was made by studying the assemblage Gt-Cd-St-Bi-Mu-Fk-AIs-Qz-HP in Kp-FeO-MgO-AIP3-Si02-Hp (KFMASH) with a Fe/Fe+Mg relationship Gt>St>Bi>Cd such as observed in most of natural pelites. A resultant grid was obtained by combining those obtained in the aboye systerns. This grid has been P-T located for PH2o =P" near QFM buffer, and excess muscovite and quartz conditions Reaction slopes in this grid were calculated within different P-T surroundings from thermodynamic data as weH as by considering the existing experimental data. In addition to the stability fields of reactions tbe P-T-XFe_Mg theoric relations for three univariant and thirteen divariant reactions have been obtained. The grid confirms the imposibility of staurolite-K feldspar and Garnet-Cordierite-Muscovite coexistence, as weH as the extension of the stability fields for Garnet-Staurolite, Cordierite-Staurolite and Garnet-Cordierite assemblages in muscovite-poor metapelites

Equilibrios minerales y zonación de granates en el nucleo del domo del Tormes (provincias de Salamanca y Zamora)

El estudio de la zonación en 1os granates de gneises pelíticos pertenecientes al núcleo del domo del Tormes indica el carácter retrógrado de estos y confirma la existencia de las siguientes reacciones observadas petrográficamente en anteriores trabajos: Gt+Als+Qz+H,O -> Cd ; Bi+Als+Qz -> Cd+Fk+H,O ; Bi+Als+Qz->Gt+Cd+Fk+H20; CaGt+Als+Qz ->Capl. El conocimiento de 1os campos de estabilidad de las reacciones que se producen en estas rocas y las observaciones petrográficas indican que ha tenido lugar la reacción de retrogradación Cd+Fk+H,O --> Bi+Mu+Qz, siendo probable además que parte del granate se haya formado según Bi+Mu+Qz -> Gt+Fk+H,O. Finalmente se propone una trayectoria P-T para 1os estadios finales de evolución del núcleo del domo basada en 1os anteriores equilibrios y en sus campos de estabilidad teóricos.Garnets in the Tormes dome core area show a conspicuous retrograde diffusion zoning. The Fe, Mg, Ca, and Mn distribution in this mineral is consistent whith the reactions Gt+Als+Qz+H,O > Cd; Bi+Als+Qz -> Cd+Fk+H,O;Bi+Als+Qz -> Gt+Cd+Fk+H,O CaGt+Als+Qz-> CaPl petrographicaly predicted in previous papers. In addition, petrographic observations contrasted with a petrogenetic grid developed for these rocks suggest that reactions Cd+Fk+H,O -> Bi+Mu+Qz and Gt+Fk+H,O -> Bi+Mu+Qz take place. Previous data allow to draw a semiquantitative P-T-t path for the latest metamorphic stages

Omaisten saama tuki ja selviytymiskeinot läheisen kuoltua

Krueger, Merja. Omaisten saama tuki ja selviytymiskeinot läheisen kuoltua. Diak Länsi, Pori, kevät 2012, 41 s., 2 liitettä. Daikonia-ammattikorkeakoulu, sosiaalialan koulutusohjelma, Diakonisen sosiaalityön suuntautumisvaihtoehto, sosionomi (AMK)+ diakonian virkakelpoisuus. Opinnäytetyö pohjautuu tutkimukselliseen tietoon. Empiirisen aineiston avulla haettiin vastausta tutkimuskysymykseen siitä, mistä läheisensä menettäneet saivat tukea ja apua silloin, kun heitä kohtasi ehkä elämänsä vaikein tilanne. Tutkimus toi samalla esille kunnan ja seurakunnan palvelutarjontaa läheisensä menettäneille. Tavoitteena oli selvittää, mistä omaiset saivat apua, minkälaista tuki oli ja kokivatko he sen tarpeelliseksi. Aineiston keruumenetelminä käytettiin kirjallisuutta, lehtiartikkeleita, opinnäytetöitä, www-sivustoja, paikallisen kunnan ja seurakunnan työntekijöiden asiantuntemusta sekä vuosina 2000 - 2010 kuolleiden henkilöiden omaisten kokemuksia. Kunnan ja seurakunnan työntekijät kertoivat vapaamuotoisesti palvelutarjonnastaan ja käytännöistään heille asetettujen kysymysten turvin. Omaisten kokemuksia koottiin haastatteluilla kyselylomakkeen avulla, joka suoritettiin henkilökohtaisesti paikkakunnan hautausmaalla. Kyselyyn osallistuivat 12 henkilöä, joista yksi oli mies ja loput naisia. Lähestymistapa opinnäytetyön aineiston keruu- ja analysointimenetelmiin oli pääsääntöisesti fenomenologisen tutkimuksen kvalitatiivista sisällön analyysiä. tutkimuksessa pyrittiin ymmärtämään inhimillisen toiminnan ja kokemuksen subjektiivista merkitystä silloin, kun ihminen on menettänyt läheisensä. Päätulokset osoittivat, että läheisten tuki oli merkittävintä pienellä paikkakunnalla, jossa sukulaisia oli runsaasti ja ihmiset tunsivat naapurustonsa. Vaikeuksia ei myöskään ollut tarpeellisen avun hakemisessa eri palveluntuottajilta niiden näkyvyyden vuoksi. Johtopäätöksenä voi pitää sitä, että tukitoimenpiteitä läheisensä menettäneille oli myös pienellä paikkakunnalla saatavissa, jos asianomainen vain halusi hakeutua niiden piiriin tai ottaa niitä vastaan. Luonnollisesti pienen paikkakunnan palvelutarjonta oli kapea-alaista, mutta tarvittaessa apua sai pyytää myös naapurikunnista ja -seurakunnista.Krueger, Merja. Relatives to Receive Subsidies And Coping Ways after The Death of a Close. 41 p., 2 appendices. Language: Finnish. Pori, Autumn 2012. Diaconia University of Applied Sciences. Degree Programme in Social Services, Option in Diaconal Social Work. Degree: Bachelor of Social Services + Deacon. The thesis based on researched empirical data. Using these data, the aim was to answer how people who had lost their near relatives got support in the situation, where they faced one of the most difficult situations in their lives. The thesis also found out what kind of services the municipality and the congregation provided to the bereaved. The research questions were, where the bereaved got support, what the quality of the support was and if they considered it valuable? The data were collected from literature, articles, theses, Internet repositories, specialists in local municipality and congregation and from interviewing people who had lost their family member during 2000 – 2010. The specialists casually explained their supply of services and their institutions. The experiences of the bereaved were collected by an enquiry conducted personally at the graveyard of the municipality. In all, 12 closest relatives responded. One of them was male and eleven female. The approach to collecting data and the analysis of the material were mainly phenomenological qualitative content analysis. The thesis was trying to understand the subjective meaning of human behaviour and experience in a situation where a family member had passed away. The main results were proved, that in a small municipality, where one had lots of relatives and people knew their neighbours, the support given by the family and intimate friends was considered most important. It seems that it was not difficult to ask for support when needed from different service providers because of their broad coverage. The conclusion was that measures of support for the bereaved was also in a small municipality, if the bereaved considered it necessary. Naturally, the services of a small municipality were restricted, but help could be solicited on demand from nearby municipalities and congregations.
