Study Of The Subjet Structure Of Quark And Gluon Jets, D. Buskulic, D., M. Thulasidas Mar 1995

Study Of The Subjet Structure Of Quark And Gluon Jets, D. Buskulic, D., M. Thulasidas

Research Collection School Of Computing and Information Systems

Measurements of the subjet structure of quark and gluon jets in hadronic Z decays are presented. The analysis is based on one million hadronic events recorded by the Aleph detector. Roughly symmetric three-jet events are selected with a coarse jet-resolution cut-off, y1. Gluon jets are identified with a purity of 94.6% in those events where evidence of long-lived heavy-flavour hadrons in the other two jets is found. The jets are then analyzed using a smaller cut-off y0 (< y1) so that subjets are resolved. The properties of the jets (subjet multiplicities (Nq), (Ng) and rates Rng(q) for n = 1, 2, 3, 4) are determined and are found to be in good agreement with the expectations of perturbative QCD as long as the subjet resolution parameter y0 is sufficiently large to keep non-perturbative effects small. In particular, the ratio , which to leading order in QCD is given by the ratio of colour factors , is measured to be 1.96 ± 0.15 for y0 = 2 · 10−3, but falls to 1.29 ± 0.03 for y0 = 1.6 · 10−5.


Formal Foundations For The Specification Of Software Architecture, Mark J. Gerken Mar 1995

Formal Foundations For The Specification Of Software Architecture, Mark J. Gerken

Theses and Dissertations

This investigation establishes a formal foundation for software architecture that allows for the specification of large, non-trivial software systems using well founded, consistency preserving construction techniques. Two fundamental problems were addressed: how to define and express architectures formally using the concept of theories, and how architecture theories can be practically applied in specification construction. The initial stages of this investigation sought to establish a formal, mathematical relationship between functional specifications of behavior and specifications defining system structure. Experimental results lead to the conclusion that architectures defining the structure of functional operations can be defined using functional logic, but more complex …


The Effect Of Repeatedly Sampling An Embedded Metamodel On The Simulation Response, John Kent Patterson Mar 1995

The Effect Of Repeatedly Sampling An Embedded Metamodel On The Simulation Response, John Kent Patterson

Theses and Dissertations

This study investigated the effect on simulation output of repeatedly sampling an embedded metamodel. A metamodel is said to be embedded within a simulation if it is used to replace a submodule of that simulation. Replacing a deterministic module with an embedded deterministic metamodel poses no apparent mathematical problems. However, using a deterministic metamodel to replace a stochastic simulation component could require additional corrective actions. This research was performed in two phases. The first phase dealt with a set of tandem queues. It was shown that as each queue was sequentially replaced with a metamodel, the total system variance was …


Analysis Of Heads-Up Display Quickening Versus Handling Qualities, Gary M. Konnert Mar 1995

Analysis Of Heads-Up Display Quickening Versus Handling Qualities, Gary M. Konnert

Theses and Dissertations

This study investigated an analytical means of selecting the quickening time constant for the standardized Heads-Up Display flight path marker. The theoretically determined time constant allowed a faster, less resource intensive means of selecting the quickening time constant. The theoretically best time constant for pilot-aircraft handling qualities was equal to the airframe pitch attitude high frequency zero time constant, Tθ2. Flight test indicated an empirical, more labor intensive method yielded better handling qualities, even though paper analysis indicated the theoretical method was better. The theoretically determined time constant gave slightly lower handling qualities. but was less costly to …

Interview: Joel Slayton, Christine Laffer

SWITCH

Interview with Joel Slayton, Professor of Computers in Fine Art at San José State University, and Director of the CADRE Institute. Slayton discusses the history of the Cadre Institute and details his views on the relationship between art and new technology. Slayton describes the role of artists in exploring the possibilities and ethical implications of emerging technologies such as genetic engineering, nano-techology, robotics, and artificial life. He describes installations and in-progress work focused on ubiquitous video surveillance. The interview concludes with a discussion of Slayton’s use of the DoWhatDo model for artistic collaboration and of his piece "Conduits," presented in …


Exploring The Use Of I/O Nodes For Computation In A Mimd Multiprocessor, David Kotz, Ting Cai Feb 1995

Exploring The Use Of I/O Nodes For Computation In A Mimd Multiprocessor, David Kotz, Ting Cai

Computer Science Technical Reports

As parallel systems move into the production scientific computing world, the emphasis will be on cost-effective solutions that provide high throughput for a mix of applications. Cost-effective solutions demand that a system make effective use of all of its resources. Many MIMD multiprocessors today, however, distinguish between ``compute'' and ``I/O'' nodes, the latter having attached disks and being dedicated to running the file-system server. This static division of responsibilities simplifies system management but does not necessarily lead to the best performance in workloads that need a different balance of computation and I/O. Of course, computational processes sharing a node with …


Psusort: A Parallel External Sort For A Shared Memory Multiprocessor System, Sujata V. Ramamoorthy Feb 1995

Psusort: A Parallel External Sort For A Shared Memory Multiprocessor System, Sujata V. Ramamoorthy

Dissertations and Theses

A method to parallelize external sorts on a shared memory multiprocessing system is presented in this thesis. The main goal of the thesis is to develop a sorting package that is scale able and efficient. No prior knowledge of the nature, source or size of the data is assumed for this work. A dynamic load-balancing architecture is used with no static allocation of tasks to processes. The package consists of an interface and a kernel. The interface provides the sort with the following - the sort input, output and temporary work spaces as abstract data types (ADTs), memory available, number …

Weighted Coverings And Packings, G. D. Cohen, Iiro Honkala, S. N. Litsyn, H. F. Mattson Jr Feb 1995

Weighted Coverings And Packings, G. D. Cohen, Iiro Honkala, S. N. Litsyn, H. F. Mattson Jr

Electrical Engineering and Computer Science - Technical Reports

In this paper we introduce a generalization of the concepts of coverings and packings in Hamming space called weighted coverings and packings. This allows us to formulate a number of well-known coding theoretical problems in a uniform manner. We study the existence of perfect weighted codes, discuss connections between weighted coverings and packings, and present many constructions for them.
