Measurement of the Top Quark Mass Using the Matrix Element Technique in Dilepton Final States

2016

We present a measurement of the top quark mass in ppbar collisions at a center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. The data were collected by the D0 experiment corresponding to an integrated luminosity of 9.7 fb-1. The matrix element technique is applied to ttbar events in the final state containing leptons (electrons or muons) with high transverse momenta and at least two jets. The calibration of the jet energy scale determined in the lepton + jets final state of ttbar decays is applied to jet energies. This correction provides a substantial reduction in systematic uncertainties. We obtain a top quark mass of mt = 173.93 +- 1.84 GeV.

Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector

2012

A search for diphoton events with large missing transverse momentum has been performed using proton–proton collision data at √s = 7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb[superscript −1]. No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalised model of gauge-mediated supersymmetry breaking with a bino-like lightest neutralino of mass above 50 GeV, gluinos (squarks) below 1.07 TeV (0.87 TeV) are excluded, while a breaking scale Λ below 196 TeV is excluded for a minimal model of gauge-mediated supersymmetry breaking. For a specific …

Towards The Adoption of a Perception-Driven Perspective in the Design of Complex Robotic Systems

2009

Awareness and autonomous interaction with the environment in a robotic system is the base of the new discipline of machine consciousness. In this paper we present the results of a first attempt in order to engineer these robotic systems by applying a Situational Method Engineering approach that extends PASSI and to create a model for conscious systems.

PERSPECTIVE RESTITUTION FROM VIEW CAMERAS PHOTOS

2022

Abstract. The paper aims at discussing the accuracy of perspective restitution from view camera photos; view cameras are non-standard cameras frequently used in the past century for on field shooting of buildings and urban sites; this is why the reconstruction of lost buildings often deals with photos taken with a view camera. The case study chosen for the proposed experiment is an urban complex built in Palermo in the ‘50s. The site features a very regular layout with surfaces at right angle, that supports the graphic reconstruction of photos’ inner and outer orientation. The site has been surveyed with a laser scanner; the point cloud provided the metric information needed for the evaluat…

Influence of Ad Congruence and Social Cues on the Probability of Choosing a Restaurant

2020

Abstract. Information processing of digital content includes conscious and un-conscious processes, memory, attitudes, and emotions and moods. Build up into the Heuristic‐Systematic Model, that states that persuasion can occur through a systematic or heuristic way, this research explores the effect of social media (SM) ratings and the ad content embedded in the SM website. Online ratings (part of the user-generated content (UGC) in SM platforms) are often heuristics cues. Subtle forms of congruence, such as the matching category between a restaurant advertiser and the third-party ad, as well as UGC, could have an impact on con-sumers’ attitudes towards the former. However, research on …

Pettis integrability of fuzzy mappings with values in arbitrary Banach spaces

2017

Abstract In this paper we study the Pettis integral of fuzzy mappings in arbitrary Banach spaces. We present some properties of the Pettis integral of fuzzy mappings and we give conditions under which a scalarly integrable fuzzy mapping is Pettis integrable.
