How to Design the Organizational Structure of An Internet Firm Under Considering Its Environment and Strategy¡VAtlas Company As an Example

Su, Chun-Jung 08 July 2002 (has links)
In the 21 Centuries after Y2K millennium bug scare, the Internet industry hottest issue is Dot-com bubble. Dot-com Company is based on Internet platform for all kind business transaction like developing, marketing, selling and service providing. During the rapidly new technology and truncated productivity cycle, the Internet business is much differ from traditional businesses, it must confront a market with fluctuation and uncertainty in every aspect. An Internet company that will survive and thrive must extremely organize their company very well for turn into Internet plays. This research is based on the reports and documents that had been announced, study the theories and method of the environment, strategy, structure, then acquire a perfect solution. Proceeding research with the physical company as an individual case, and identify the possibility of the structure established, finally conclude the study and provide a solution to any company that is in the same field. After the solid study, this research comes out following conclusions: 1.While organizing a business enterprise¡¦s structure, it must consider environment and strategy simultaneously. 2.The development of the business enterprise, certainly affected by environment but when the environments impact the business, business must adjust the structure to respond to the environments quickly. 3.No matter what kind of structure that business enterprise used,organizational design should be flexible and responsive. 4.Strategy and structure are the most import to a business enterprise, a business enterprise is hardly to resist or change the environments, but it can adjust itself to be following the trend.

Predicting Femoral Geometry from Anatomical Features

Grondin Lazazzera, Jerome 30 April 2014 (has links)
Knee replacement surgery is a common orthopaedic procedure that greatly benefits from a three-dimensional geometric representation of a patient's knee bone obtained from MR or CT data. The use of these image modalities pose the following challenges: (i) high imaging cost; (ii) long wait times; (iii) limited availability and (iv) in the latter, large exposure to ionizing radiation. Traditional approaches based on planar X-ray radiography are significantly less prone to these issues; however, they only provide two-dimensional information. This work presents a proof of concept study for generating patient-specific femoral bone shapes from a statistical shape atlas using anatomical features acquired from calibrated X-ray radiographs. Our hypothesis was: three-dimensional geometry can be reconstructed, within 2 millimeters RMS, by identifying features on two calibrated radiographs. We illustrate the feasibility of our approach with regards to acquiring features and the viability of reconstructing patient-specific bony anatomy. A set of reliable and relevant features is identified for which an acquisition protocol and user-interface was devised to minimize inter-observer variability. Both the data and methods used to construct the atlas are discussed as well generating shapes from features. The reconstructions accuracy was comparable to, albeit lower than, competing approaches that rely on two-dimensional bony contours. / Thesis (Master, Computing) -- Queen's University, 2014-04-29 21:53:10.809

A search for Higgs-portal dark matter and new phenomena with monojet signatures in pp collisions at √s = 8 TeV

Pearce, James D. 21 December 2015 (has links)
A search for new phenomena in final states with one or more energetic jets and large missing transverse momentum, ETmissT, is presented. An integrated luminosity of 20 fb-1 is collected from √s = 8 TeV pp collisions at the LHC with the ATLAS detector during 2012 operations. A selection criteria is imposed requiring events to have monojet signatures, with ETmissT > 350 GeV and no identified leptons. Standard Model backgrounds and systematics uncertainties are estimated using a maximum likelihood procedure. The number of events passing this selection criteria is in good agreement with Standard Model expectations. These events are then divided up into three orthogonal signal regions based on the outputs of two Random Forest classifiers trained to classify invisible decays of the Higgs boson produced through the vector boson fusion and Higgs-strahlung production modes. These results are then interpreted in terms of three different Higgs-portal models and translated into upper limits on WIMP-nucleon cross-sections for comparison with direct detection experiments. / Graduate

Measurement of dijet production at √s = 7 TeV with the ATLAS detector

Jones, Graham January 2011 (has links)
A measurement using the ATLAS detector has been made of the fraction of events in proton-proton collisions at √s = 7 TeV that do not contain additional jets in the rapidity region bounded by a di-jet system. This provided a strong test of perturbative QCD in the new energy regime of the Large Hadron Collider. Additional measurements have been made of the mean jet multiplicity in the rapidity bounded region and using a variety of different event selections. These observation were compared to recent next to leading order dijet predictions produced by POWHEG and a variety of leading order generators.

Search for supersymmetry in final states with multiple bottom quarks with the ATLAS detector

Ghasemi Bostanabad, Meisam 09 July 2021 (has links)
The theoretical development of the Standard Model in the 1960s and 1970s has led to the discovery of its missing piece, the Higgs boson, at the ATLAS experiment (together with its sister experiment, CMS) at the Large Hadron Collider at CERN in 2012. In order to solve the problem of large quantum corrections to the leading expansion of the Higgs boson mass, additional symmetries need to be added to the Standard Model. A possible solution to this problem of Higgs mass quantum corrections is the theory of Supersymmetry, which includes partners to each Standard Model particle, such as gluinos, squarks, and the lightest supersymmetric particle. This dissertation describes a search for pair-produced gluinos, where each gluino decays via a top squark or a bottom squark to the lightest supersymmetric particle (a neutralino). Events which contain a large jet multiplicity in the final state (i.e. at least four jets of which at least three must be b-jets), and large amounts of missing transverse energy, are obtained for further studies. The dataset used for this search includes 139 fb^−1 of integrated luminosity recorded by the ATLAS experiment between 2015 and 2018 at a center-of-mass energy √s = 13 TeV. No significant excess is observed in data above the Standard Model backgrounds, and gluino masses up to 2.3 TeV for both the Gtt and the Gbb models are excluded at a 95% confidence level. This dissertation also contains an overview of, and the author’s work on, the data quality monitoring of the ATLAS liquid argon calorimeter during 2017 data taking. / Graduate
