    Penyimpanan data saat ini terdapat dua jenis yakni relational database dan non-relational database. Kedua jenis DBMS (Database Managemnet System) tersebut berbeda dalam berbagai aspek seperti per-formansi eksekusi query, scalability, reliability maupun struktur penyimpanan data. Kajian ini memiliki tujuan untuk mengetahui perbandingan performansi DBMS antara Oracle sebagai jenis relational data-base dan MongoDB sebagai jenis non-relational database dalam mengolah data terstruktur. Eksperimen dilakukan untuk mengetahui perbandingan performansi kedua DBMS tersebut untuk operasi insert, select, update dan delete dengan menggunakan query sederhana maupun kompleks pada database Northwind. Untuk mencapai tujuan eksperimen, 18 query yang terdiri dari 2 insert query, 10 select query, 2 update query dan 2 delete query dieksekusi. Query dieksekusi melalui sebuah aplikasi .Net yang dibangun sebagai perantara antara user dengan basis data. Eksperimen dilakukan pada tabel dengan atau tanpa relasi pada Oracle dan embedded atau bukan embedded dokumen pada MongoDB. Response time untuk setiap eksekusi query dibandingkan dengan menggunakan metode statistik. Eksperimen menunjukkan response time query untuk proses select, insert, dan update pada MongoDB lebih cepatdaripada Oracle. MongoDB lebih cepat 64.8 % untuk select query;MongoDB lebihcepat 72.8 % untuk insert query dan MongoDB lebih cepat 33.9 % untuk update query. Pada delete query, Oracle lebih cepat 96.8 % daripada MongoDB untuk table yang berelasi, tetapi MongoDB lebih cepat 83.8 % daripada Oracle untuk table yang tidak memiliki relasi.Untuk query kompleks dengan Map Reduce pada MongoDB lebih lambat 97.6% daripada kompleks query dengan aggregate function pada Oracle

    The Lean method entails a set of standardized processes intending to optimize resources, reduce waste, and improve results. Lean has been proposed as an operative model for the Covid-19 outbreak. Herein, we summarized data resulted from the Lean model adoption in an Emergency Department of the Lombardy region, the Italian epicenter of the pandemic, to critically appraise its effectiveness and feasibility. The Lean algorithm was applied in the Humanitas Clinical and Research Hospital, Milan, north of Italy. At admission, patients underwent outdoor pre-triage for fe-ver, respiratory, and gastrointestinal symptoms, with a focus on SpO2. Based on these data, they were directed to the most appropriate area for the Covid-19 first-level screening. High-risk patients were assisted by trained staff for second-level screening and planning of treatment. Out of 7.778 patients, 21.9% were suspected of SARS-CoV-2 infection. Mortality was 21.9% and the infection rate in health workers was 4.8%. The lean model has proved to be effective in optimizing the overall management of Covid-19 patients in an emergency setting. It allowed for screening of a large volume of patients, while also limiting the health workers’ infection rate. Further studies are necessary to validate the suggested approach

    Applicazioni di livello “0” della metodologia utilizzata per la valutazione del rischio sismico di Sistemi Urbani, utilizzando l’analogia delle reti neuronali

    Get PDF
    Questa ricerca, condotta nell’ambito del Progetto RELUIS – Linea 10, ha riguardato la messa a punto di un modello di rischio sismico per Sistemi Urbani con approccio multilivello, utilizzando l’analogia con le reti neuronali. Il primo passo è stata l’elaborazione del livello 0, basato su banche-dati, disponibili a livello nazionale, relative alla pericolosità sismica di base e locale (INGV) e a dati di censimento dei comuni italiani (ANCITEL 2001; ISTAT 2001) per la descrizione fisica e funzionale dei centri abitati/sistemi urbani analizzati. Per semplicità e per omogeneità tra i molti dati elaborati sono stati trascurati due aspetti rilevanti per il modello di rete neuronale, che intervengono invece ai livelli successivi, ovvero l’aspetto della “soglia” di perdita di capacità di una componente di sottosistema (sia per evoluzione che per connessione) e l’aspetto della “capacità iniziale” di una componente di sottosistema prima dell’evento sismico. La valutazione della perdita di capacità complessiva di un Sistema Urbano a livello 0 è stata quindi calcolata come l’insieme delle perdite di tutti i sistemi combinati tra loro (con opportuni pesi) e quindi con un valore complessivo

    Le nouveau cirque américain

    Get PDF
    On peut dire que depuis ses débuts, vers les 1870, le cirque américain a connu des périodes où il aspirait au grand art et où il empruntait au théâtre des artistes, des techniques et la dramaturgie. Ce n’est qu’en 1975, lorsque des artistes ont abandonné l’idéal américain de la grandeur pour adopter le modèle européen de la piste simple que ce mouvement a connu son véritable essor. Le Big Apple Circus, le Pickle Family Circus, le Cirque du Soleil et Circus Flora ont réussi à théâtralisé le cirque américain. Même le géant du cirque à trois pistes, le Ringling Bros. and Barnum & Bailey, a commencé à donner à ses spectacles une allure plus théâtrale. Le Midnight Circus, Circus Sarasota ainsi que Barnum’s Kaleidoscape, entre autres, ont continué à trouver de nouvelles façons d’allier le cirque et le théâtre. Des écoles de cirque ont été fondées afin de fournir aux nouveaux cirques des artistes formés aux nouvelles techniques. Tous visent à faire évoluer le cirque vers la forme d’art à laquelle il a toujours aspiré.Almost from its very beginning, in the 1870's, the American circus has gone through periods when it aspired to high art and borrowed artists, techniques and dramaturgy from the theatre. It was not until 1975, when certain artists abandoned the all-American ideal that bigger was always better and opted, instead, to model their new circuses after the European model of the one ring circus, that this movement began to gain momentum. The Big Apple Circus, The Pickle Family Circus, Cirque du Soleil, and Circus Flora were leaders in the movement to theatricalize the American circus. Eventually even the three-ring giant, Ringling Bros. and Barnum & Bailey, began to refashion its performance in a more theatrical manner. These early circuses were followed by the Midnight Circus, Circus Sarasota and Barnum's Kaleidoscape, among others, which continued to find new ways of melding circus and theatre. To provide performing artists for these new circuses, new circus schools had to be founded to train the artists in the new style and technique demanded by the new circuses. Together the artists and the various circuses are seeking to have the circus evolve into the unique art form it has always hoped to be

    Introduction. Postambulatory hand swelling (PAHS) seems to be common in the general population. There are few mention in the medical literature. The objective were (1) to identify prevalence; (2) to compare gender and age groups; (3) to determine if dog owners and walkers are more or less prone. Materials and Methods. 1009 semirandomly surveys were completed from walkers. Age, gender, and dog ownership were assessed. We discussed, among dog owners, whether or not they walk their dog regularly, whether or not they notice swollen hands after walking, and, if so, if the swelling resolves over 24 hours or persists. Results. 699 females and 410 males, among whom, 28.9% of females but only 16.3% of males reported PAHS (P < 0.001). Surprisingly, those with swelling were statistically younger than those without (49.2 versus 52.8 years, P = 0.003), and dog owners were more likely than nonowners to report swelling (28.1% versus 21.7%; P = 0.015). In terms of persistent swelling, this was observed in twice the percentage of females as males (13.3 versus 6.5%) and tended to involve older subjects (54.0 versus 48.8 years), but with no statistical difference significance. Conclusions. PAHS is a relatively common phenomenon, seemingly more common in females

    A review and bibliometric analysis of utilizing building information modeling (BIM) on effective operation and maintenance (O&M)

    Get PDF
    Developments in information technology can facilitate the planning and implementation of sustainable development. Building Information Modeling (BIM) is one such technology that can be utilized to achieve this goal. BIM has now reached dimensions of 6D and even 7D, with 6D BIM being used for energy analysis and 7D BIM for facility management during the operational and maintenance period of a building. This paper aims to discuss patterns, gaps, and trends in the utilization of BIM for effective building operation and maintenance. Bibliometric data mapping was conducted using VOSviewer® software, and 219 scholarly bibliographic records from the Scopus database between 2009 and 2023 were analyzed. The results showed that the highest publication growth was in 2021, with 36 publications (16.44%). China published the most articles, with 74 (29.84%). Recent research reviews indicate that BIM can facilitate the O&M process of a facility, including maintenance and repair, energy management, and security. However, there are still many challenges related to the BIM 7D function, such as data interoperability issues and the need for a framework for using BIM. The study also examines the application of BIM 7D in Indonesia. Further research is needed to balance the utilization of BIM for facility management with its application for asset management

    The Borexino Thermal Monitoring & Management System and simulations of the fluid-dynamics of the Borexino detector under asymmetrical, changing boundary conditions

    Full text link
    A comprehensive monitoring system for the thermal environment inside the Borexino neutrino detector was developed and installed in order to reduce uncertainties in determining temperatures throughout the detector. A complementary thermal management system limits undesirable thermal couplings between the environment and Borexino's active sections. This strategy is bringing improved radioactive background conditions to the region of interest for the physics signal thanks to reduced fluid mixing induced in the liquid scintillator. Although fluid-dynamical equilibrium has not yet been fully reached, and thermal fine-tuning is possible, the system has proven extremely effective at stabilizing the detector's thermal conditions while offering precise insights into its mechanisms of internal thermal transport. Furthermore, a Computational Fluid-Dynamics analysis has been performed, based on the empirical measurements provided by the thermal monitoring system, and providing information into present and future thermal trends. A two-dimensional modeling approach was implemented in order to achieve a proper understanding of the thermal and fluid-dynamics in Borexino. It was optimized for different regions and periods of interest, focusing on the most critical effects that were identified as influencing background concentrations. Literature experimental case studies were reproduced to benchmark the method and settings, and a Borexino-specific benchmark was implemented in order to validate the modeling approach for thermal transport. Finally, fully-convective models were applied to understand general and specific fluid motions impacting the detector's Active Volume.Comment: arXiv admin note: substantial text overlap with arXiv:1705.09078, arXiv:1705.0965
