A verification of the Optimal Jet Finder
نویسنده
چکیده
The optimal jet definition discovered in [1] purports to provide a final theoretical answer to the problem of finding the best jet definition. A practical version of the answer was provided in [2] in the form of a fortran-77 code; its beta (OJF_013) was available on the web at [3]. The first working version of the algorithm was first developed in the object-oriented language Component Pascal using the rapid application development environment BlackBox Component Builder [4]. The BlackBox brings the best features of the Oberon System [5] to commercial environments. Component Pascal is a fine-tuning of the seminal programming language Oberon which has been influencing the software development world in a profound way, and a heir to the famous Pascal and Modula-2 [6]. A superb and unmatched combination of a fast compiler producing high-quality code; strict type safety of the meticulously designed language; and a highly dynamic software development environment allowed to perform the necessary experimentation and find a minimization algorithm to serve as a basis for a fortran implementation which evolved independently to accommodate the fine-tunings of the jet definition (reported in the January 2000 revision of [1]). Large scale tests by Pablo Achard [7] demonstrated usefulness, stability and a good speed of the fortran beta code (OJF_013). However, the following problems were seen:

Optimal Jet Finder
We describe a FORTRAN 77 implementation of the optimal jet definition for identification of jets in hadronic final states of particle collisions. We discuss details of the implementation, explain interface subroutines and provide a usage example. The source code is available from http://www.inr.ac.ru/∼ ftkachov/projects/jets/
متن کاملAirflow inside tunnel boring machine: A numerical study and an experimental verification
Knowledge of the airflow distribution inside a Tunnel Boring Machine (TBM) can create a safe working environment for workers and machinery. The airflow quality and the related mass flow rate in the ventilation system should be sufficient to dilute gases and remove dust inside the tunnel. In this work, airflow distribution in the single shield TBM tunnel was studied using computational fluid dyn...
متن کاملDispelling the N 3 myth for the k t jet - finder Matteo Cacciari and Gavin
At high-energy colliders, jets of hadrons are the observable counterparts of the perturbative concepts of quarks and gluons. Good procedures for identifying jets are central to experimental analyses and comparisons with theory. The kt family of successive recombination jet finders has been widely advocated because of its conceptual simplicity and flexibility and its unique ability to approximat...
متن کاملModeling and Multi-Objective Optimization of Stall Control on NACA0015 Airfoil with a Synthetic Jet using GMDH Type Neural Networks and Genetic Algorithms
This study concerns numerical simulation, modeling and optimization of aerodynamic stall control using a synthetic jet actuator. Thenumerical simulation was carried out by a large-eddy simulation that employs a RNG-based model as the subgrid-scale model. The flow around a NACA0015 airfoil, including a synthetic jet located at 10 % of the chord, is studied under Reynolds number Re = 12.7 × 106 a...
متن کاملDevelopment of a Mathematical Model for Prediction of Pollutants Emission in D. I. Diesel Engines
Major pollutants emission from Direct-Injection (D.I) diesel engines are predicted by means of a mathematical model. In order to construct such a model, an integral Multi-Zone Combustion Model (MZCM) is formulated, which basically consists of jet mixing and combustion submodels. In MZCM, variation of injection pressure is considered. Also time period of ignition delay is predicted by considerin...
