description: We provide the most precise measurement of the WW production cross section in p-pbar collisions to date at a center of mass energy of 1.96 TeV, and set limits on the associated trilinear gauge couplings. The WW->lvl'v (l,l'=e,mu) decay channels are analyzed in 1 fb^(-1) of data collected by the D0 detector at the Fermilab Tevatron Collider. The measured cross section is sigma(p-pbar -> WW) = 11.5 +/- 2.1 (stat + syst) +/- 0.7 (lumi) pb. One- and two-dimensional 95% C.L. limits on trilinear gauge couplings are provided.

description: Additional file 4:. Fig. S2. Regression tree for change in ULT MPR at 6 months. Regression tree results for change in ULT MPR from baseline to 6 months, with negative change indicating a decrease in MPR. The tree was allowed to consider all baseline variables that were used in any analyses. The goal was to identify whether there were any subgroups in which the intervention was efficacious. This would have been indicated by the appearance of ‘group’ at one of the split points in the tree. Our regression tree does not show ‘group’ at any split points in the tree. To interpret; each oval contains the mean MPR in that group (top number) and percent of the cohort (bottom number). The oval at the top of the graph indicates an overall mean change in MPR of -6% among the whole cohort (100%). Each split represents a dichotomization of the data with ‘yes’ on the lest and ‘no’ on the right. So, the first split was chosen by the algorithm as baseline MPR ≥43 (bl_mpr ≥ 43), those meeting the condition (‘yes’, on the left) had a mean decrease in MPR of -9.2 and comprised 87% of the cohort; those with baseline MPR <43 had a mean increase in MPR of 15 and represented the remaining 13% of the cohort. On the left side, those with baseline MPR ≥43 were then further subdivided by baseline SATMED effectiveness score ≥ 4. Those meeting this condition represented 76% of the cohort with a mean decrease in MPR of 11 vs. the 11% of the cohort with baseline SATMED effectiveness <4 with a mean 6-month MPR increase of 2.3.

description: We employ two simple and robust results to constrain the mixing matrix of the isosinglet scalar mesons $f_0(1710)$, $f_0(1500)$, $f_0(1370)$: one is the approximate SU(3) symmetry empirically observed in the scalar sector above 1 GeV and confirmed by lattice QCD, and the other is the scalar glueball mass at 1710 MeV in the quenched approximation. In the SU(3) symmetry limit, $f_0(1500)$ becomes a pure SU(3) octet and is degenerate with $a_0(1450)$, while $f_0(1370)$ is mainly an SU(3) singlet with a slight mixing with the scalar glueball which is the primary component of $f_0(1710)$. These features remain essentially unchanged even when SU(3) breaking is taken into account. The observed enhancement of $ωf_0(1710)$ production over $ϕf_0(1710)$ in hadronic $J/ψ$ decays and the copious $f_0(1710)$ production in radiative $J/ψ$ decays lend further support to the prominent glueball nature of $f_0(1710)$. We deduce the mass of the pseudoscalar glueball $G$ from an $η$-$η'$-$G$ mixing formalism based on the anomalous Ward identity for transition matrix elements. With the inputs from the recent KLOE experiment, we find a solution for the pseudoscalar glueball mass around $(1.4\pm 0.1)$ GeV, which is fairly insensitive to a range of inputs with or without Okubo-Zweig-Iizuka-rule violating effects. This affirms that $η(1405)$, having a large production rate in the radiative $J/ψ$ decay and not seen in $γγ$ reactions, is indeed a leading candidate for the pseudoscalar glueball. It is much lower than the results from quenched lattice QCD ($>2.0$ GeV) due to the dynamic fermion effect. It is thus urgent to have a full QCD lattice calculation of pseudoscalar glueball masses.

description: Circumstellar discs are expected to be the nursery of planets. Grain growth within such discs is the first step in the planet formation process. The Bok globule CB 26 harbours such a young disc. We present a detailed model of the edge-on circumstellar disc and its envelope in the Bok globule CB 26. The model is based on HST near-infrared maps in the I, J, H, and K bands, OVRO and SMA radio maps at 1.1mm, 1.3mm and 2.7mm, and the spectral energy distribution (SED) from 0.9 microns to 3mm. New photometric and spectroscopic data from the Spitzer Space Telescope and the Caltech Submilimeter Observatory have been obtained and are part of our analysis. Using the self-consistent radiative transfer code MC3D, the model we construct is able to discriminate parameter sets and dust properties of both its parts, namely envelope and disc. We find that the disc has an inner hole with a radius of 45 +/- 5 AU. Based on a dust model including silicate and graphite the maximum grain size needed to reproduce the spectral millimetre index is 2.5 microns. Features seen in the near-infrared images, dominated by scattered light, can be described as a result of a rotating envelope. Successful employment of ISM dust in both the disc and envelope hint that grain growth may not yet play a significant role for the appearance of this system. A larger inner hole gives rise to the assumption that CB 26 is a circumbinary disc.

Effective utilisation of mobile GIS technology : exploring user acceptance within the utility industry
Creators: name: Luttrell, Ross
Publisher: name: University Of Tasmania
Year: 2023

description: Recent advancements in mobile geographic information system (GIS) technology can provide utility authorities with exciting new opportunities to efficiently and effectively manage their infrastructure assets. However, a significant factor for the successful implementation of such technology is the acceptance and utilisation by its users. A review of the literature has determined that there is a considerable body of knowledge regarding the purpose and use of geographic information systems. However, there is very little research in the area of user technology acceptance in relation to mobile GIS technology. This exploratory study establishes an overview of the uptake of mobile GIS in water, gas and electricity utilities in Australia and New Zealand. It also examines user acceptance with reference to the Technology Acceptance/Task-Technology Fit model proposed by Dishaw and Strong (1999). Since it was not possible to locate a pre-validated instrument it was necessary to establish one for the specific purposes of this research. This questionnaire was constructed with reference to the integrated technology acceptance model from Dishaw and Strong (1999). The research focussed on the perceptions of GIS or Infrastructure Asset Managers in relation to the attitudes and behaviours of end users towards the utilisation of mobile GIS technology. A key finding of this exploratory research is that a majority of water, gas and electricity utilities in Australia and New Zealand are using, or are in the process of implementing, mobile GIS. The research also found that GIS managers perceive that training increases the end users acceptance and adoption of mobile GIS technology, whereas the age of end users does not appear to be a factor influencing acceptance or rejection of the technology. It is proposed that even though this research is exploratory in nature, it has made a number of theoretical and practical contributions to knowledge.
Portfolio diversification : a theoretical and empirical analysis
Creators: name: Crawford, Graeme Frederick
Publisher: name: University of British Columbia
Year: 2011

description: This thesis presents a technique for analysing the relationships between the number of securities in a diversified portfolio and portfolio return and variance of return. It includes an analytical and descriptive presentation of the concepts and objectives of portfolio analysis in a theoretical framework. The material presented is used as a vehicle to introduce an empirical analysis of the portfolio selection process. For the empirical analysis a model is developed to simulate the selection process for the optimum portfolio. This is similar to that derived by using the quadratic programming technique of the Markowitz model. The utility function used for the selection of the optimal portfolio at each stage of diversification is of the form suggested by Farrar. The ex post data for the empirical analysis consists of ten samples of fifteen securities selected from the Financial Post Data Bank and only common stock is considered. The period covered is from 1959 to 1969 using annual data. The results derived show the form of the efficient portfolio frontier under varying degrees of aversion to risk. The optimum portfolio for either a mildly risk averse or an extremely risk averse investor should consist of approximately four to six securities under the assumptions of the model.

description: The COVID-19 pandemic, caused by the novel coronavirus SARS-CoV-2, has had a profound and far-reaching impact on the global economy since its emergence in late 2019. With millions of people affected worldwide, companies have had to adapt quickly to the new situation, leading to significant changes in the labor market. As a result, companies' hiring patterns have changed, creating new challenges and opportunities for organizations. Given the ongoing uncertainty and potential for further disruption, there is a growing need for a predictor to help organizations respond to these new hiring patterns and make informed decisions about their talent acquisition strategies.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We explicitly construct the k-essence models which reproduce the arbitrary FRW cosmology, that is, the arbitrary time-development of the scale factor or the Hubble rate. The k-essence model includes scalar quintessence model, tachyon dark energy model, ghost condensation model as special cases. Explicit formulas of the reconstruction are given. First we consider the case that the action only contains the kinetic term. In this case, we find that the model reproducing the development of the universe in the exact $Λ$CDM model cannot be constructed although there is a model which reproduces the development infinitely closing to $Λ$CDM model. We find, however, the solution is not stable. Another is more general case including potential etc., where we find that there appear infinite number of arbitrary functions of the scalar fields, which are redundant to the time development of the scale factor. By adjusting one of the redundant functions, however, we can obtain the model where any solution we need could be stable.

The cimmerian and the elysian : how musical and extra-musical models and expressive ethos affect the compositional process
Creators: name: Hill, Adam B.
Publisher: name: University Of Tasmania
Year: 2023

description: This exegesis is a document of my rediscovery of emotion and expression in my music. It is also a chronicle of my acknowledgement and incorporation into my methodology of my many influences. Moreover, it is a recounting of how I utilized emotion, expression, and my various influences in the creation of the folio compositions. There are two primary aspects that unify the compositions in the folio. The first aspect is the diversity of musical and extra-musical models, such as art music, popular music, literature, and films, which influence the compositional process. The second aspect is that an expressive ethos, defmed as a general affective or emotional state that expressively informs the composition, characterizes each work and affects the compositional process. There are two basic types of expressive ethos that are represented in the folio compositions. The first type I call \cinunerian\" and it is concerned with what might be considered negative emotional states such as anger grief or fear. The second one the \"elysian\" ethos is concerned with what might be considered positive emotional states such as happiness excitement or joy. Most of the folio compositions represent either the cirrunerian or elysian ethos. However there are a few compositions that do not represent merely one expressive state but are concerned with the transformation from one ethos to the other typically from the cimmerian to the elysian. I refer to the transformation of the expressive ethos in these compositions as \"protean.\" In the exegesis I clearly define the above features clarify their relationship to music history explain my compositional methodology and demonstrate the role of each aspect throughout the process. I provide a brief discussion of my placement literally and aesthetically in music history (Chapter 1) focusing primarily on my relationship to three prominent trends in the twentieth century. I also discuss how I formulated compositional and aesthetic conclusions and how they informed my current praxis (Chapter 2). In the chapters focusing on the cinunerian (Chapter 3) elysian (Chapter 4) and protean (Chapter 5) works I explain in detail each ethos and how I utilize musical and extra-musical influences in my compositions. In short this exegesis examines with examples from the folio how I am incorporating more traditional affective techniques and past tonal practices as they have been filtered through and influenced by the musical environment of the last century."

description: We present a strategy to quantify the performance of jet definitions in kinematic reconstruction tasks. It is designed to make use exclusively of physical observables, in contrast to previous techniques which often used unphysical Monte Carlo partons as a reference. It is furthermore independent of the detailed shape of the kinematic distributions. We analyse the performance of 5 jet algorithms over a broad range of jet-radii, for sources of quark jets and gluon jets, spanning the energy scales of interest at the LHC, both with and without pileup. The results allow one to identify optimal jet definitions for the various scenarios. They confirm that the use of a small jet radius (R\simeq 0.5) for quark-induced jets at moderate energy scales, O(100 GeV), is a good choice. However, for gluon jets and in general for TeV scales, there are significant benefits to be had from using larger radii, up to R\gtrsim 1. This has implications for the span of jet-definitions that the LHC experiments should provide as defaults for searches and other physics analyses.

description: Mayall II = G1 is one of the most luminous globular clusters (GCs) in M31. Here, we determine its age and mass by comparing multicolor photometry with theoretical stellar population synthesis models. Based on far- and near-ultraviolet GALEX photometry, broad-band UBVRI, and infrared JHK_s 2MASS data, we construct the most extensive spectral energy distribution of G1 to date, spanning the wavelength range from 1538 to 20,000 A. A quantitative comparison with a variety of simple stellar population (SSP) models yields a mean age that is consistent with G1 being among the oldest building blocks of M31 and having formed within ~1.7 Gyr after the Big Bang. Irrespective of the SSP model or stellar initial mass function adopted, the resulting mass estimates (of order $10^7 M_\odot$) indicate that G1 is one of the most massive GCs in the Local Group. However, we speculate that the cluster's exceptionally high mass suggests that it may not be a genuine GC. We also derive that G1 may contain, on average, $(1.65\pm0.63)\times10^2 L_\odot$ far-ultraviolet-bright, hot, extreme horizontal-branch stars, depending on the SSP model adopted. On a generic level, we demonstrate that extensive multi-passband photometry coupled with SSP analysis enables one to obtain age estimates for old SSPs to a similar accuracy as from integrated spectroscopy or resolved stellar photometry, provided that some of the free parameters can be constrained independently.

The key idea is to set up a V-system with two far-off resonant lasers by coupling the ground state to two excited electronic states. The lasers interact through the ac Stark shift of the ground state and thereby acquire a large conditional phase shift.

Solar evaporation of liquid effluent from composting toilets in cool temperate climates
Creators: name: Holman, DP
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis investigates the design of a solar powered evaporator aimed at reducing visual intrusion of composting toilet infrastructure on the natural landscape. A series of tests were undertaken beginning in the laboratory, progressing to outdoor conditions at the University ofTasmania in Hohart and culminating in a field test in the Mt Field National Park in southern Tasmania. This field test involved the substitution of the field test evaporator for an existing unit at the Government Huts composting toilet facility. A method for gathering the data to enable matching of evaporator size to effluent output rate was also evaluated. The performance related objectives were realized by increasing evaporative efficiency over the existing National Parks and Wildlife Service (NPWS) design and achieving flexibility in siting through good evaporative performance in cold and diffiise light conditions. Over a twelve month period of operation in an alpine location the 1.5m x 1.5m solar evaporator dealt with all the liquid effluent from two public composting toilets. A method for gathering the necessary empirical evidence to properly match evaporator size to toilet loading was also tested at Mt Field resulting in the calculation of average figures for the volume of liquid expelled to the evaporator per toilet use.

We also present a reanalysis of VLBI observations made by us on June 1999 and by other authors on February 2005. We conclude that, contrary to our earlier claim of strong deceleration in the expansion, SN 1979C has been undergoing almost-free expansion ($m = 0.91\pm0.09$; $R \propto t^m$) for over 25 years.

A study of various computational methods for determining time optimal control of time delay system
Creators: name: Morse, James Gregory
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis some numerical techniques for obtaining the time optimal control of a class of time delay systems are studied and compared. The delays may be fixed or time varying. The delay systems considered, which need not be linear or time invariant, are those for which the time optimal control is bang-bang. The optimal control is found by carrying out a search in switching interval space. The method of Rosenbrock⁽²’³⁾ is used to find the switching intervals which maximize a performance index of the final states and terminal time. Kelly's⁽²¹⁾ method of gradients is shown to be applicable to systems with time varying time delays by using the costate equations of ref. [10]. The perturbations in the control are chosen in such a way that the descent in function space is changed to a steepest descent in switching interval space. In a third approach, a technique similar to that of Bryson and Denham⁽¹⁹⁾ is used to account for the terminal conditions directly. All the methods are illustrated by examples. The advantages of the direct search based on Rosenbrock's method are a) ease of programming and b) rapid convergence close to the optimum. However, initial convergence is slow when compared to that of either gradient method. Of the two gradient methods, that based on a penalty function approach was superior in ease of programming and convergence close to the optimum to that based on a descent to the final target set. Neither gradient scheme could match the rapid convergence of the Rosenbrock method close to the optimum

Electromagnetic compatibility : compliance with emerging regulations
Creators: name: Johnson, PL
Publisher: name: University Of Tasmania
Year: 2023

description: Over the past three years, Electromagnetic Compatibility (EMC) has emerged as a critical aspect of electrical and electronic design. In particular, this field of study has moved from being a specialist \stand alone\" discipline undertaken by research institutes and the military to a topic that is of concern to everybody dealing with electrical/electronic products or services. The main impetus for this lift in profile has been the recent introduction of legislation concerning EMC which has been universally adopted by all member countries of the European Union (EU). This legislation initially introduced in 1992 is referred to as \"the EMC directive 89/336/EEC\" and is widely regarded as \"the most comprehensive complex and possibly contentious directive ever to emanate from Brussels\". The EMC Directive has not only unified the EMC requirements for trade throughout the European Union but has effectively led the way for EMC standards throughout the commercial world. The main objectives of this thesis are to outline the basic principles of EMC detail the requirements of the latest standards and associated testing techniques and to illustrate the issues that need to be addressed by design engineers in order to achieve EMC compliance. A practical and economical EMC test set up is documented and measurement results obtained from Switch-Mode Power Supply equipment are compared to fully calibrated measurements taken at a third party test house in order to determine the accuracy and thus usefulness of these \"pre-compliance\" test measurements."

Beginning of the Super-Soft Phase of the Classical Nova V2491 Cygni

description: We present the results of soft X-ray studies of the classical nova V2491 Cygni using the Suzaku observatory. On day 29 after outburst, a soft X-ray component with a peak at ~0.5 keV has appeared, which is tantalising evidence for the beginning of the super-soft X-ray emission phase. We show that an absorbed blackbody model can describe the observed spectra, yielding a temperature of 57 eV, neutral hydrogen column density of 2x10^{21} cm^{-2}, and a bolometric luminosity of ~10^{36} erg s^{-1}. However, at the same time, we also found a good fit with an absorbed thin-thermal plasma model, yielding a temperature of 0.1 keV, neutral hydrogen column density of 4x10^{21} cm^{-2}, and a volume emission measure of ~10^{58} cm^{-3}. Owing to low spectral resolution and low signal-to-noise ratio below 0.6 keV, the statistical parameter uncertainties are large, but the ambiguity of the two very different models demonstrates that the systematic errors are the main point of concern. The thin-thermal plasma model implies that the soft emission originates from optically thin ejecta, while the blackbody model suggests that we are seeing optically thick emission from the white dwarf.

Casimir Energy of the Universe and New Regularization of Higher Dimensional Quantum Field Theories
Creators: name: Ichinose, Shoichi
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Casimir energy is calculated for the 5D electromagnetism and 5D scalar theory in the {\it warped} geometry. It is compared with the flat case. A new regularization, called {\it sphere lattice regularization}, is taken. In the integration over the 5D space, we introduce two boundary curves (IR-surface and UV-surface) based on the {\it minimal area principle}. It is a {\it direct} realization of the geometrical approach to the {\it renormalization group}. The regularized configuration is {\it closed-string like}. We do {\it not} take the KK-expansion approach. Instead, the position/momentum propagator is exploited, combined with the {\it heat-kernel method}. All expressions are closed-form (not KK-expanded form). The {\it generalized} P/M propagators are introduced. We numerically evaluate $\La$(4D UV-cutoff), $\om$(5D bulk curvature, warp parameter) and $T$(extra space IR parameter) dependence of the Casimir energy. We present two {\it new ideas} in order to define the 5D QFT: 1) the summation (integral) region over the 5D space is {\it restricted} by two minimal surfaces (IR-surface, UV-surface) ; or 2) we introduce a {\it weight function} and require the dominant contribution, in the summation, is given by the {\it minimal surface}. Based on these, 5D Casimir energy is {\it finitely} obtained after the {\it proper renormalization procedure.} The {\it warp parameter} $\om$ suffers from the {\it renormalization effect}. The IR parameter $T$ does not. We examine the meaning of the weight function and finally reach a {\it new definition} of the Casimir energy where {\it the 4D momenta(or coordinates) are quantized} with the extra coordinate as the Euclidean time (inverse temperature). We examine the cosmological constant problem and present an answer at the end. Dirac's large number naturally appears.

Publisher: name: arXiv

Subjects: subject: Logic (math.LO)

subject: 06A12; 20M10

description: We study varieties with a term-definable poset structure, "po-groupoids". It is known that connected posets have the "strict refinement property" (SRP). In [arXiv:0808.1860v1 [math.LO]] it is proved that semidegenerate varieties with the SRP have definable factor congruences and if the similarity type is finite, directly indecomposables are axiomatizable by a set of first-order sentences. We obtain such a set for semidegenerate varieties of connected po-groupoids and show its quantifier complexity is bounded in general.
Analysis of the potential institutional demand in processed desserts for British Columbia tree fruits
Creators: name: Barry, Michael Thomas
Publisher: name: University of British Columbia
Year: 2011

description: The tree fruits industry in British Columbia distributes its products in both fresh and processed forms. The processed fruit industry, through Sun-Rype Products Limited, a wholly owned subsidiary of B.C. Tree Fruits Limited, is an important and profitable part of the tree fruits industry in British Columbia. Expansion of this industry, however, depends upon finding new market opportunities. The purpose of this paper was to gather information on the size and characteristics of the British Columbian institutional market for frozen fruit-based desserts. Such an investigation appeared essential given the facts that the number of processed fruit products were very limited and institutions were increasing both their share of the food dollar and their consumption of frozen foods. Obtaining the necessary information involved the collecting of all relevant published data as well as the conducting of personal interviews. The published data were limited but did provide both a general background on the institutions' food requirements and statistics on gross sales. To break these gross statistics down into more meaningful potential dessert sales required interviewing several Greater Vancouver institutions. These interviews provided data on various food costs and more detailed information on dessert requirements. The results of the investigation indicated that the demand of the British Columbian institutional market for frozen fruit-based desserts was not large but the costs of producing, marketing, and shipping such desserts would also have to be examined before a final decision to enter or not to enter the market was made.
Torque measurement
Creators: name: Lim, SS
Publisher: name: University Of Tasmania
Year: 2023

description: There are many ways of measuring torque in electrical machines. Recent advances in transducer technologies means that measurement of torque will be more precise and easy. Traditionally, slip rings have been used for telemetering for measurement on meters and microcomputer systems. This project formed part of the Torque Measurement project carried out together with 2 other undergraduate project partners, Mr. Lye Teik Tan and Mr. Yi Fu Sia. This project thesis investigates the possibility of using optoelectronics to remotely transfer torque signals digitally (from a set of strain gauges connected in bridge configuration) to a microcomputer thus eliminating the use of slip rings. It also details the designing, fabrication, testing, calibration of the hardware and software used in the research.

description: We provide a detailed study of gravitational reheating in quintessential inflation generalizing previous analyses only available for the standard case when inflation is followed by an era dominated by the energy density of radiation. Quintessential inflation assumes a common origin for inflation and the dark energy of the Universe. In this scenario reheating can occur through gravitational particle production during the inflation-kination transition. We calculate numerically the amount of the radiation energy density, and determine the temperature $T_*$ at which radiation starts dominating over kination. The value of $T_*$ is controlled by the Hubble parameter $H_0$ during inflation and the transition time $Δt$, scaling as $H_0^2 [\ln(1/H_0Δt)]^{3/4}$ for $H_0 Δt \ll1$ and $H_0^2 (H_0 Δt)^{-c}$ for $H_0Δt \gg 1$. The model-dependent parameter $c$ is found to be around 0.5 in two different parametrizations for the transition between inflation and kination.

On the probability distribution of power fluctuations in turbulence

Year: 2009
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study local power fluctuations in numerical simulations of stationary, homogeneous, isotropic turbulence in two and three dimensions with Gaussian forcing. Due to the near-Gaussianity of the one-point velocity distribution, the probability distribution function (pdf) of the local power is well modelled by the pdf of the product of two joint normally distributed variables. In appropriate units, this distribution is parameterised only by the mean dissipation rate, $ε$. The large deviation function for this distribution is calculated exactly and shown to satisfy a Fluctuation Relation (FR) with a coefficient which depends on $ε$. This FR is entirely statistical in origin. The deviation from the model pdf are most pronounced for positive fluctuations of the power and can be traced to a slightly faster than Gaussian decay of the tails of the one-point velocity pdf. The resulting deviations from the FR are consistent with several recent experimental studies.

description: We report on the first creation of ultracold bosonic heteronuclear molecules of two fermionic species, 6Li and 40K, by a magnetic field sweep across an interspecies s-wave Feshbach resonance. This allows us to associate up to 4x10^4 molecules with high efficiencies of up to 50%. Using direct imaging of the molecules, we measure increased lifetimes of the molecules close to resonance of more than 100 ms in the molecule-atom mixture stored in a harmonic trap.

Appraisal of Dr. Broom's top management game
Creators: name: Gibberd, John Davidson
Publisher: name: University of British Columbia
Year: 2011

description: The objective of the thesis is to examine Dr. Broom's Top Management Game. The examination covers the realism of model input output relationships, the cost of an application, the design structure utilized and the adequacy of the model presentation. Before the analysis is undertaken two analytical tools are developed. The first of these is a management game typology which provides a standardized, method for describing gaming models. The second tool is a two dimensional matrix which may be employed for design or analytical purposes. The rows of the matrix represent input for the current period and the columns output for the current period. In order to determine the feasibility of converting The Broom Game, to modular design, the structure of a modular game is outline. Dr. Broom's Game, is an educational model which employs the computer to calculate the results for a period. Though the model is supposedly total enterprise the personnel function is absent. The marketing function of the model performs in a highly unrealistic manner. Also the production function is inadequate in that no attempt is made to break production into its component parts. The cost of an application is approximately two dollars. In the authors opinion it is not feasible to convert the model to modular design. Finally the administrators' presentation was found to be inadequate.
