Two approaches were used to evaluate multiple-use inventories. The first approach was to analyze inventory data currently being collected. Assuming that all variables being inventoried are necessary in making decisions for multiple-use management, simple correlation, multiple linear regression, and factor analysis techniques were employed. Data from the Jefferson National Forest in Virginia were analyzed but no strong association between variables currently being observed was detected. The second approach was to define the decisions that are to be made and the variables necessary to make these decisions. Once the variables have been defined, sampling intensity must be determined. The decision-maker was not required to define the sampling intensity based on experience or a rule-of thumb, but rather a cost-loss function for multiple inventories and multiple decisions was minimized. The cost of collecting data will increase as sample size increases, while the expected monetary loss that will occur to the decision-maker from making decisions with inventory data will decrease. Minimizing the cost-loss function determines the sampling intensity that will provide the lowest total (cost plus loss) monetary cost to the decision-maker. Methods were developed to determine necessary information for the cost-loss function, and several methods of minimization were evaluated. / Doctor of Philosophy

The thesis is focused on the control of batch processes on recipe basis. The objective of this thesis is to create a philosophy of control batch processes using programming languages SCL and CFC. In the theoretical part of the work, the automation of production are explained and the principles of the control of batch processes based on recipes in accordance with standard S88 are described. In the last part there is a draft concept of such a procedure without the use of batch-oriented type systems like Batch is.

Magnetic flux continually emerges from the Sun, rising through the solar interior, emerging at the photosphere in the form of sunspots and expanding into the atmosphere. Observations of sunspot rotations have been reported for over a century and are often accompanied by solar eruptions and flaring activity. In this thesis, we present 3D numerical simulations of the emergence of twisted flux tubes from the uppermost layers of the solar interior, examining the rotational movements of sunspots in the photospheric plane. The basic experiment introduces the mechanism and characteristics of sunspot rotation by a clear calculation of rotation angle, vorticity, magnetic helicity and energy, whereby we find an untwisting of the interior portion of the field, accompanied by an injection of twist into the atmospheric field. We extend this model by altering the initial field strength and twist of the sub-photospheric tube. This comparison reveals the rotation angle, helicity and current show a direct dependence on field strength. An increase in field strength increases the rotation angle, the length of fieldlines extending into the atmosphere, and the magnetic energy transported to the atmosphere. The fieldline length is crucial as we predict the twist per unit length equilibrates to a lower value on longer fieldlines, and hence possesses a larger rotation angle. No such direct dependence is found when varying the twist but there is a clear ordering in rotation angle, helicity, and energy, with more highly twisted tubes undergoing larger rotation angles. We believe the final angle of rotation is reached when the system achieves a constant degree of twist along the length of fieldlines. By extrapolating the size of the modelled active region, we find rotation angles and rates comparable with those observed. In addition, we explore sunspot rotation caused by sub-photospheric velocities twisting the footpoints of flux tubes.

The main theme of this thesis is creating HMI applications for a program written in standard S88 with trying of function control system. The introductory section is devoted to the standard S88 with introduction of the main concepts and description of design control system. Other parts are devoted to the description of the CIP station, a program description and requirements for HMI and introduction of HMI performance. The last part deals with the testing functions of the control system in simulation.

This thesis deals with the batch controlling of a distillation column model. The thesis is divided into several parts. The first part, which is more theoretical, summarizes the description of the batch controlling, the distillation process and the equipment used, including the model of the distillation column itself. The second part is focused on the practical implementation. The beginning of this part displays different types of the models produced by the Standard 88. This section is followed by a description of a device database in the environment of FactoryTalk Batch Equipment Editor, creation of a logical phase codes using functions of the PhaseManager in the environment of RSLogix5000 and a creation of a recipe in the environment of FactoryTalk Batch Recipe Editor. The last part of this thesis deals with the visualization created in the FactoryTalk View Studio SE and final testing of the entire process.

This thesis is an analysis of the manner in which the persona and works of Ben Jonson were appropriated – between the Restoration, in 1660, and the retirement of David Garrick, in 1776 – to reflect the political and social concerns of the age. Unlike previous studies, rather than primarily focusing on the stage history of Jonson, I analyse a wide range of sources – produced both within and outwith the theatre – in order to explore, across a variety of media, a breadth of material which appropriates the playwright and his works. I shall consider in my first main chapter the appropriations of Jonson within the Restoration court, in particular noting the assimilation of the playwright's work to what might be styled a proto-Tory ideology, as well as the way in which his plays could mirror the destabilising effects of the king's romantic liaisons. In my second chapter, I explore the moral reformation at the turn of the eighteenth century, in which we can see appropriations of Jonson which cast his works as being primarily didactic. The third chapter moves the narrative of the thesis into the years of the premiership of Sir Robert Walpole. I shall consider the way in which the playwright's works – especially The Alchemist and Eastward Ho! – were seen as being especially relevant to an age of speculation and mercantile endeavour, as well as examining the manner in which the figures of Sejanus and Volpone were appropriated to mock the increasingly unpopular premier. In the final chapter, I shall offer an analysis of Garrick's seminal portrayal of Drugger in the contexts of the political philosophy of the mid-eighteenth century, considering the manner in which it was interpreted alongside the character's further appropriations by Francis Gentleman. The thesis concludes by exploring political appropriations of Jonson up to the present day.
