مکانیزم شکست ناشی از خزش در طی حادثه شدید یک رآکتور‌ آبی‌تحت‌فشار به‌جهت انتقال مواد رادیواکتیو به محیط‌زیست اهمیت ویژه‌ای برخوردار است. دنبال شدید، حرارت واپاشی منتقل‌شده سایر قسمت‌های سیستم‌خنک‌کننده رآکتور می‌تواند منجر گرم‌شدن سازه‌های سیستم خنک‌کننده (RCS) و خرابی نواحی تحت‌فشار آسیب‌پذیر شود. قطع‌کامل‌برق (SBO) بدون اقدامات اپراتور (توالی TMLB) یکی محتمل‌ترین سناریوهایی است که ممکن یکپارچ...

The Large Hadron Collider (LHC) will enter a new phase beginning in 2027 with the upgrade to High Luminosity LHC (HL-LHC). increase number of simultaneous collisions coupled more complex structure single event result each experiment collecting, storing, and processing exabytes data per year. amount generated and/or collected greatly outweighs expected available computing resources.

Networks around the world, especially Research and Education (R&E) networks are increasing capacity and striving for higher availability and reliability. However, improved performance is not guaranteed. Network monitoring services often deploy a distributed infrastructure of nodes that perform end-to-end path measurements such as one-way delay, packet losses, and achievable throughput. An examp...

We present the methods for off-line -jet identification developed for the study of decay modes of the neutral SUSY Higgses of mass 140 300 GeV in CMS. Detector response is simulated with a GEANT-based package CMSIM. Involving calorimetry and tracker information, -jet selection criteria allow to reduce the backgrounds to an acceptable level while keeping the selection efficiency at the level of ...

In this paper, we propose a novel approach, called SENATUS, for joint traffic anomaly detection and root-cause analysis. Inspired from the concept of a senate, the key idea of the proposed approach is divided into three stages: election, voting and decision. At the election stage, a small number of senator flows are chosen to represent approximately the total (usually huge) set of traffic flows...

In this talk we will review the major additions and improvements made to the ROOT system in the last 18 months and present our plans for future developments. The additions and improvements range from modifications to the I/O sub-system to allow users to save and restore objects of classes that have not been instrumented by special ROOT macros, to the addition of a geometry package designed for ...

A large BaF2 detector array along with its dedicated CAMAC electronics and VME based data acquisition system has been designed, constructed and installed successfully at VECC, Kolkata for studying high energy γ rays (>8 MeV). The array consists of 162 detector elements. The detectors were fabricated from bare barium fluoride crystals (each measuring 35 cm in length and having cross-sectional ar...

The concept of Virtual Monte Carlo (VMC) has been developed by the ALICE Software Project to allow different Monte Carlo simulation programs to run without changing the user code, such as the geometry definition, the detector response simulation or input and output formats. Recently, the VMC classes have been integrated into the ROOT framework, and the other relevant packages have been separate...

Depth distributions of positron-emitting nuclei in PMMA phantoms are calculated within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit (version 8.0). The calculated total production rates of C, C and O nuclei are compared with experimental data and with corresponding results of the FLUKA and POSGEN codes. The distributions of e annihilation points are obtained by s...
