Charged jet cross section and fragmentation in proton-proton collisions at √s = 7 TeV
2019

Further distribution of this work must maintain attribution to the author(s) and the published article’s title, journal citation, and DOI. We report the differential charged jet cross section and jet fragmentation distributions measured with the ALICE detector in proton-proton collisions at a center-of-mass energy √s=7 TeV. Jets with pseudorapidity |η|40 GeV/c, the pythia calculations also agree with the measured charged jet cross section. pythia6 simulations describe the fragmentation distributions to 15%. Larger discrepancies are observed for pythia8. SCOAP
Measurement of the Lund jet plane using charged particles in 13 TeV proton-proton collisions with the ATLAS detector
2020
The prevalence of hadronic jets at the LHC requires that a deep understanding of jet formation and structure is achieved in order to reach the highest levels of experimental and theoretical precision. There have been many measurements of jet substructure at the LHC and previous colliders, but the targeted observables mix physical effects from various origins. Based on a recent proposal to factorize physical effects, this Letter presents a double-differential cross-section measurement of the Lund jet plane using 139 fb−1 of √s=13 TeV proton-proton collision data collected with the ATLAS detector using jets with transverse momentum above 675 GeV. The measurement uses charged particles to ac…
Uncertainty under Norway’s claimed exclusive rights over the Snow crabs in the Archipelago of Svalbard
2019
This thesis explains the legal framework in the Archipelago of Svalbard with an emphasis on the Loophole area. The author will answer the question on what is regulating the Svalbard archipelago and can Norway claim exclusive rights over snow crab. Snow Crab as a resource residing also in the Loophole area has already attracted attention and brought two fishing ships before the Supreme Court of Norway. This thesis explains how the situation has evolved by giving the historical background of the area of Svalbard, provide an overview of the current legal framework, lastly, a case law analyses.
New computational techniques for finite-difference Weighted Essentially Non-Oscillatory schemes and related problems
2014
High-Resolution Shock-Capturing (HRSC) schemes constitute the state of the art for computing accurate numerical approximations to the solution of many hyperbolic systems of conservation laws, especially in computational fluid dynamics. A drawback of these schemes is that most of them use the spectral decomposition of the Jacobian matrix of the system to compute the numerical approximations by local projections to characteristic fields. The numerical solutions obtained are often excellent in terms of resolution, but the computational effort needed may be too high for some problems, especially those for which the spectral information of the flux Jacobian matrix is not available or is quite di…
Transformaciones multiescala no lineales
2013
La transformada wavelet y la multirresolución à la Harten son dos herramientas matemáticas que han sido aplicadas con éxito al tratamiento de señales digitales. En los últimos años, este campo ha experimentado un creciente interés debido a sus múltiples aplicaciones como, entre otras, la compresión de imágenes, eliminación de ruido, reconocimiento de patrones, recuperación de fotografías, en campos tan diversos como la Informática, Física, Medicina o Ingeniería. Iniciamos esta tesis con la revisión de estos conceptos. En 1993 A. Harten, [A. Harten. Discrete multiresolution analysis and generalized wavelets. J. Appl. Numer. Math., 12:153–192 (1993)], generaliza un cierto tipo de wavelets bio…
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
2011
Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb−1 recorded at the Large Hadron Collider. The anti-k t algorithm is used to identify jets, with two jet resolution parameters, R=0.4 and 0.6. The dominant uncertainty comes from the jet energy scale, which is determined to within 7% for central jets above 60 GeV transverse momentum. Inclusive single-jet differential cross sections are presented as functions of jet transverse momentum and rapidity. Dijet cross sections are presented as functions of dijet mass and the angular variable χ. The res…
Problemas multiplicativos relacionados con la división de fracciones : un estudio sobre su enseñanza y aprendizaje
2013
Los estudiantes tienen dificultades para asociar el enunciado de un problema multiplicativo con la operación que permite resolverlo; esta investigación identifica los tipos de problemas multiplicativos que los estudiantes reconocen como de división de fracciones. Mediante el análisis histórico-epistemológico de textos de enseñanza sobre tres épocas históricas y ocho períodos diferentes, se obtiene un listado de variables de enseñanza (algoritmos, sentidos de uso de fracción y de división de fracciones, representaciones, problemas), así como los valores de dichas variables. Se localizan en los textos consultados algunas reglas particulares y seis algoritmos generales, cuyo predominio ha vari…
The BRICS Centres of Dispute Resolution: causes, state of the art, and prospects
2023
The idea of an enhanced cooperation and exchange of knowledge and best practices among its member states in the fields of trade, commerce, and investments -among others- is at the heart of BRICS. In fact, intra-BRICS trade has nearly tripled over the last decade, supported by an increase in intra-regional trade for all member countries. Thanks to their influential and remarkable progress in promoting local currency (for de-dollarisation purposes), regional FDI, and regional trade, the BRICS economies have emerged and have taken a new space in the twenty-first century. This reinforced one of the core objectives pursued by BRICS which is that of enhancing the five developing economies’ role i…
