Purpose – The purpose of this paper is to utilise market-oriented methodologies and simulation analysis to generate information regarding consumers’ attitudes, opinions and preferences towards novel β-glucan-enriched breads. Design/methodology/approach – Focus Groups and In-depth interviews were used to generate consumer information on potentially suitable attributes that would maximise consumer acceptance. The approach involved the creation of a set of realistic product concepts from a combination of attribute levels and the presentation of these product concepts to consumers. A fractional factorial design generated an orthogonal array of 22 hypothetical products that were presented to consumers for rating while K-means cluster analysis was used to segment consumers into four specific consumer segments. The simulation analysis then identified β-glucan-enriched bread concepts targeted specifically at these four market segments. Findings – The simulation analysis identified β-glucan-enriched bread concepts targeted specifically at these four market segments. Originality/value – This research can assist manufacturers who wish to optimally design foods with novel ingredients and aid in the development of product concepts which maximise consumer acceptance and increase the likelihood of product success.

In this paper a vehicle dynamics model is presented, which is an example that contains all the necessary aspects of making a decent vehicle model. Several examples show the use of such a model: basic vehicle dynamics phenomena can be recognized with the simulation of a detailed vehicle model. We are dealing with the connection between downforce and under/oversteer in this paper. In addition, the use of numerical simulations in the field of control systems is pointed out by an example of simulating an ABS control for the vehicle.

Abstract This paper considers algorithms simulating the implementation of distributed two-phase locking (2PL) protocols in distributed database systems and simulation results. It describes specifically the simulations of two-version 2PL and 2PL with integrated timestamp ordering mechanism. Integrated modelling algorithms for deadlock avoiding are suggested in the paper: twoversion architecture of database and timestamp ordering strategy “wait-die”. The results of the simulations of these two variants of the 2PL method at different scales of the networks for data transmission and at different intensities of inflow transactions are also presented. Modelling algorithms are developed by means of the system for simulation modelling GPSS World Personal Version.

In this thesis we analysed the behaviour of crowd flows in large gatherings, taking a case study of the corridors where the Sa'yee ritual are performed. Of the current simulation models few of them addressed disabled persons in their model calculations and they did not include real-life data in order to analyse the crowd behaviour. None of the crowd modelling and simulation studies of the Hajj crowd, focused mainly on crowd behaviours during the Sa'yee ritual. We have proposed and developed a methodology to extract crowd characteristics from real-life videos with unknown camera angle and position. Agent tracking for different conditions of weather and various walking styles have been studied in the scope of our study. We further tested the feasibility of the use of drone to track agent behaviour in our methodology. We propose, design, and develop, a realistic and flexible state-based model of the Sa'yee ritual that can be mapped onto different agent-based systems, and then implement it in the modelling platforms Netlogo and FLAME. Further a comparison is made in terms of processing speed so that the model could be escalated to larger crowd. There are two enhancements carried out in the Sa'yee model and simulations, that makes this research novel and different than other contemporary researches. The first is the addition of different types of people (men, women and people with disabilities), and the second is the use of real video recordings from CCTV to analyse and model the walking behaviours of pilgrims. We carried out experiments that define the safety limit for the number of people in a group, and the results of defining a dedicated corridor for the disabled population. An empirical study shows that some aspects of the model such as agent density, behaviour, and speed match the real Sa'yee crowd. Therefore, the model can be used to study the general crowd behaviour in terms of agent density and speed of the agents with only slight modifications. The model is mapped from Netlogo to FLAME which validates that our model can be extrapolated to simulate larger crowd and huge number of agents. In addition, safety guidelines for better crowd management have been proposed to enhance crowd flow and reduce risks.

The work in this thesis is aimed primarily at developing a vehicle ride simulation program based on a generalised vehicle model formulation to evaluate the effect of various system parameters on the ride quality of a vehicle, and secondly to develop an optimisation scheme for determining the optimum setting of suspension parameters as related to ride comfort. The simulation program can accommodate the non-linearity of the suspension components such as tyres, shock absorbers and suspension springs. Based on a twin tube shock absorber in production, a damper model was developed. This damper model was included in a vehicle model and was run in parallel with the simulation program. A variety of vehicle models were developed and simulated in the time domain with various road obstacles such as half-sine, half-circle and ramp, and the results are presented. In order to improve the accuracy of the simulated response in the time domain, an attempt has been made to find the wheel envelope as it passes an obstacle. Based on a real car in production, two different vehicle models were developed and simulated in the frequency domain and the simulated responses were compared with those obtained from experiments. A series of tests were carried out on a test vehicle on the ride simulator and the transient responses were compared with those obtained from the simulation program. Attempts were made to improve the accuracy of the simulated response by inclusion of bilinear damper models in the simulation process. Several studies has been made to investigate the effect of various vehicle system parameter on the overall ride performance.

This thesis looks at the use mathematical modelling, in particular the use of simulation as a solution technique, when applied to the problem of the study of infectious diseases. The thesis examines two different routes of infection of the bacteria Chlamydia trachomatis - the sexually transmitted disease Chlamydia, and the ocular disease Trachoma. Several simulation models are developed within the thesis. The exploration of Chlamydia results in a prototype model which it is suggested could be extended in a future project. The work exploring Trachoma resulted in the development of a model useful in the evaluation of intervention strategies, as well as the statistical analysis of data which provides the necessary data for the modelling work. The analysis provides values for the duration of Trachoma infection, and for the incidence of the infection; figures which have previously not been available.

The effect of substrate surface topology on the interaction of living cells with inanimate substrates is a well-established phenomenon. When cells are placed on biomaterials, they outgrow protrusions called filopodia that sense surface features in their immediate surroundings and initiate the formation of stable cell adhesion complexes closer to the cell body. Adhesion proteins permit filopodia to constantly explore the surrounding microenvironment. A better understanding of the relationship of filopodia with surface features is highly relevant for exploiting custom-made surfaces to guide cell activity.
In this work, mathematical modeling and simulation were used to describe different phenomena related to the interaction of a filopodium with its microenvironment, with the aim of reproducing experimentally observed phenomena associated to filopodia growth and interactions with substrates. The Kelvin Voigt model was used for the viscoelastic response of filopodia. Result predict filopodia protrusion under test conditions and helps improving our understanding on the effect of substrate topology on the biomechanical response of filopodial extensions.

Detailed information of the underlying mechanisms of macromolecular disintegration processes is not always fully available from lab-based experiments and GPC. A powerful computer simulation technique was thus indispensable in this respect whilst saving time, labour and expense. This project aims to develop an interactive computer program to capture the behaviour of a complex reactor and offer the following functionality: mathematical calculations, graph/chart generation, processing simulation-experiment pertaining to user-given scission and environmental characteristics, data saving and re-loading etc, Windows-style menu-driven interfaces provide templates for easy implementation of complex mathematical algorithms -a new simulation technique (Slider interfaces) presented in the thesis, based on cellulose-ageing study in electrical transformers (Heywood, 2000). A novel statistical concept was introduced to significantly improve real-tune performance of mathematical calculations to simulate polymer chain fragmentation phenomena, enabling transformation of the simple iterative to a semi-iterative and instant calculation algorithm. Three new mathematical functions were constructed - (a) Monte Carlo Dynamic (Slider), (b) Algebraic Exact, (c) Markov Statistical models, initially using an arbitrary time scale for degradation. Real-time simulation was developed using three time model variants that included the interpretation of deviations in the order reaction rate from linearity to an exponential type function. The above transformation enhanced reproducibility and accuracy of degraded MWD curve sampling whilst then- graphical display & clarity via 'Cubic B-Spline' smoothing-algorithm. Complex models were created from a ranking ensemble of single scission mechanisms, structured with levels of probability constructs to effectively simulate GPC-like curve-deformities and side-shifts. The simulation results provided new information in the following key areas: the temporal shift patterns of MWD/PCLD under different ageing conditions graphical comparisons between simulated and observed Idnetic and scission parameters. the dominant types of scission strategy at different reactor conditions, the dependence of reaction behaviour on the polymer structural order. An alternative way of predicting life expectancy of an ageing polymer via relating time- temperature to the magnitude of intermediate MWD curve shifts that is independent on DP. The latter is an average value and subjected to errors. An equation was derived for this. Introduction of a binary tree "death time" algorithm for calculation of the life expectancy of different categories of polymer chain species. Non-iterative techniques developed here opens up new avenues of further research. The developed algorithms and computer program may provide ample scope for investigating the ageing of other industrially important polymers and can be utilised in other areas of polymer research with little modification where probability distribution is sought.

The dispersion and migration behavior of hydrocarbon products leaking at low rates (i.e. 1bbl/day and 10 bbl/day) from a pipeline have been studied using a combination of experimental leakage tests and numerical simulations. The focus of this study was to determine the influence of subsurface engineered boundaries associated with the trench walls, and the presence of a water table, upon the leakage behavior of a range of hydrocarbon products. The project numerically modelled three products including diesel, diluted bitumen (dilbit) and gasoline; which were chosen to span a range of fluid types and viscosities. Laboratory simulations of leakage were carried out for the most viscous product (i.e. dilbit) in order to capture plume dispersion in semi-real time, and to allow numerical predictions to be assessed against experimental data. Direct comparisons between observed plume dimensions over time and numerically predicted behavior suggested a good match under low moisture conditions, providing confidence that the numerical simulation was sufficiently reliable to model field-scale applications. Following a simulated two year initialization period, the leakage of products, their associated gas phase migration, thermal and geomechanical effects were simulated for a period of 365 days. Comparisons between product leakage rate, product type and soil moisture content were made and the spatial impacts of leakage were summarized. Variably compacted backfill within the trench, surrounded by undisturbed and more compacted natural soils, results porosity and permeability differences which control the migration of liquids, gases, thermal effects and surface heave. Dilbit migration is influenced heavily by the trench, and also its increasing viscosity as it cools and degases after leakage. Diesel and gasoline liquid plumes are also affected by the trench structure, but to a lesser extent, resulting in wider and longer plumes in the subsurface. In all cases, the migration of liquids and gases is facilitated by higher permeability zones at the base of the pipe. Volatile Organic Compounds (VOCs) migrate along the trench and break through at the surface within days of the leak. Temperature changes within the trench may increase due liquid migration, however the change in predicted temperature at the surface above the leak is less than 0.5�C above background. For gasoline, the large amount of degassing and diffusion through the soil results in cooling of the soil by up to 1�C. Induced surface displacement was predicted for dilbit and for one case of diesel, but only in the order of 0.2cm above baseline. Based upon the information gathered, recommendations are provided for the use and placement of generic leak detection sensor types (e.g liquid, gas, thermal, displacement) within the trench and / or above the ground surface. The monitoring locations suggested take into account requirements to detect pipeline leakage as early as possible in order to facilitate notification of the operator and to predict the potential extent of site characterization required during spill response and longer term remediation activities.
