TV-apparater och kringutrustningar är numera ofta Internetanslutna och har inbyggda webbläsare som fungerar som en plattform för HTML5- applikationer med JavaScript, vilket har lett till att utbudet av applikat- ioner som finns tillgängliga på dessa plattformar ökat explosivt de senaste åren. Tyvärr lider dock många av dålig prestanda med avseende på dataö- verföring och användargränssnittet upplevs ofta som segt eftersom hård- varan inte kan mäta sig med en modern dator. Det här examensarbetet undersöker vad som kan optimeras på närverkssidan. Två metoder för optimering har utvärderats - cache och komprimering av data från både applikationspaket och externa källor till slutanvändaren. Mätningar har gjorts på en befintlig TV-applikation för att identifiera var det finns störst utrymme för förbättringsåtgärder. Jämförelser mellan olika lösningar visar att vissa metoder kan snabba upp särskilda processer betydligt, me- dan andra metoder t.o.m. kan ha en negativ effekt. De lösningar som visat bäst resultat med avseende på snabbhet har implementerats i den befint- liga applikationen. Hänsyn till lämplighet av drift och underhåll av lös- ningarna har också tagits. Resultatet av dessa optimeringar visar att det med relativt enkla metoder går att avsevärt förbättra användarupplevelsen för Internetanslutna TV- applikationer, bl.a. har uppstartstiden visats kunna minskas med ca 80 % i de tester som utförts. / As televisions and peripheral devices nowadays often are Internet con- nected and has built-in web browsers that work as a platform for HTML5 applications running JavaScript, the range of applications available on these platforms has increased drastically. However, many suffer from poor performance in terms of data transfer and the user interface is often experienced as slow since the hardware cannot compare to a modern desktop computer. This thesis examines what can be optimized on the networking side. Two optimization methods have been evaluated - caching and compression of data of both the application package and external resources to the end user. Measurements have been made on an existing TV application to identify which parts have biggest room for im- provements. Comparisons between the various solutions show that some methods can speed up specific processes significantly, while other methods even may have a negative effect. The solutions that have shown the best results based on the speed improvements have been implemen- ted in the existing application. Consideration of the suitability of the maintenance of the solutions were also taken. The results of these optimizations show that relatively simple methods can significantly improve the user experience for an connected TV appli- cations. For instance, a reduction of about 80 % of the startup time has been measured in the performed tests.

FPGAs provide parallel computing that is fit for speeding up the computation of a large range of problems. Programming an FPGA involves a complex tool flow for which several CAD tools have been developed. These tools compute solutions to many problems such as packing, placement, and routing, which map a circuit design onto an FPGA. These computations require a great deal of memory, of which the Routing Resource Graph contributes the most of any individual data structure. If the RRGraph could be represented in a more compact manner, performance of the tool flow algorithms may be improved due to an increase in memory caching benefits. This work presents four variations on RRGraph folding which vary in memory usage reduction and runtime, with the most aggressive method reducing the RRGraph size by up to 4x while maintaining similar performance to the original representation.

Fertilizer, feed and machinery dealers we re interviewed to obtain the extent of the services which they provided to farmers in Cache County. One machinery dealer provided a service in the form of a rental program while all others provided none. Fertilizer dealers provided spreaders while feed dealers provided only a delivery service. The Farm Service Division of the Amalgamated Sugar Company was examined as a case study. Budgets for different sizes of beet growers were formulated and compared to evaluate the services provided. It was determined that the farmers in the 0-10 acre category received a net return per acre of $107.36 while the farmers in the over 40 acre category who did not use the service received a net return per acre of $105.00. It was deduced that the Farm Service Division was a benefit to the smaller farmers. Problems which the farmers encountered with the services were discussed, and a theoretical model of the services was presented. Recommendations were given for improvements in the services.

Snowmobiling is one of the major outdoor winter sports in Cache County, Utah. Despite its popularity, it has run into several problems, among which the most noticeable is its conflict with other winter recreationists, namely, cross-country skiers and snowshoers. In order to resolve this conflict, one must first understand more about each group involved. As such, the purpose of this research was to obtain information on the snowmobiler in Cache County, Utah. Specifically, the objectives of the study were: (1) to identify the attitudes of the snowmobiler toward leisure and the environment; (2) to identify and compare occupations, SES, and social characteristics with studies in other regions; (3) to identify and compare aspects such as when, where, and why they go snowmobiling and the areas preferred by them with studies in other regions; and (4) to identify their other leisure-time activities. To collect the data, the names of the Cache County snowmobilers were obtained from tax assessment receipts at the Cache County Courthouse. From a total list of 501 names, a sample of 250 was selected by a simple random procedure. A questionnaire composed of Burdge's Leisure Orientation Scale, an environmental orientation scale, and usage, ownership, and demographic questions was sent to the sample population with a 59 percent usable return rate. The data was then analyzed by the following SPSS programs to meet the objective of the study: marginals, t-test, and chi square. Analysis of the data revealed the following major characteristics of the Cache County, Utah snowmobilers: (1) They are typically male, married with between three and four children per family, have a high school education or above, have a median income above the median income for Utah of $9,320.00, and hold either a blue- or white-collar occupation. (2) They hold a slight preservationist orientation toward the environment. (3) They have a moderately strong leisure orientation. (4) They snowmobile primarily on weekends with friends or family with the primary area of use being the Cache National Forest. (5) The main reason for buying or still owning a snowmobile was "snowmobiling for pleasure." Upon comparison with the findings of this research with studies conducted in other regions, the conclusion is reached that the Cache County, Utah snowmobilers are much like their counterparts in other regions of the country.

A liquefaction opportunity map was developed for Cache Valley, Utah. The study was the initial phase to determine the potential for liquefaction in Cache Valley. The method used in this study to develop the liquefaction opportunity map was based on a procedure developed by Youd and Perkins (1977). This opportunity map is proposed to be combined with a map delineating liquefaction susceptible soils to produce a liquefaction potential map. The liquefaction susceptibility map is being developed in a companion study. The liquefaction potential map will assist in the evaluation of earthquake response in general and microzonation in particular. The liquefaction potential map may also be used by contractors, consultants, governmental organizations, etc., for preliminary planning and decision making to determine the suitability of a given site.

The goal of this project was to analyze Cache County for potential sanitary landfill sites covering the period 2020 to 2120. The county population and per capita solid waste were estimated. The minimum landfill size was then calculated. A geographic information system (GIS) was used for data storage and vii analysis. Relevant data were gathered. Areas which would not support a landfill were eliminated. Remaining sites were rated as having slight, moderate, or severe restrictions for use as an area method sanitary landfill based on the Natural Resource Conservation Service (NRCS) Sanitary Facility Report, and the NRCS Soil Interpretations Rating Guide. Seventeen sites were designated as sites for further evaluation. A landfill ranking system giving a primary and/or secondary rating to data items was developed. Nine prime sites had one secondary (.,a ting. These sites should be more closely investigated to determine which are the best potential sites. (136 pages)

The migration and production of indigenous populations of brown, brook, and cutthroat trouts in Spawn Creek, Cache County, Utah, were studied in 1973 and 1974 to elucidate the role of this stream vis- a - vis the rest of the watershed . Spawn Creek and its watershed were described climatically, hydrologically , geologically , vegetatively, recreationally, and chemically. The prevalent, aquatic taxa of fauna and flora were also listed. The equipment and techniques used in the study t o collec t data, including a two-way fish trap and electro- fishing gear, were delineated . The collected data consisted of periodic estimates of mean weight and density stratified by year classes . These year classes were separated by length-frequency histograms, the length of individuals of known age , and the determination of age via counts of annuli on scales. This last method of aging was adjusted for the failure of cutthroat trout to form an annulus in their first year of life . The estimates of density were obtained through a modified form of the two-catch removal estimator. This estimator was designed to correct the estimates for emigration from the sampled area between the two sampling efforts . The biases in several unmodified multi-catch removal e , · imators vis- a-vis the populations of trout in Spawn Creek were discussed relative to the different , individual sizes of several year classes. Mathematical models to describe t he time-dependent growth and density were constructed from the von Bertalanffy equation and the equation of depensatory mortality, respectively, by adding trigonometric components to each. The added constraints imposed by these components were discussed for models of both growth and dens ity . These models were fitted to the appropriate , periodic estimates of growth and density to provide functions of these states vis-a-vis time. The calculation of production for each year class consisted of differentiating the appropriate model of growth, multiplying the resultant differential equation by the appropriate model of density , and integrating the product for various interval s of time. A numerical routine for integration was used when the solution of the integral of the aforementioned product was unattainable in closed form . The basic alogarithm of this routine was discussed. The periodic estimates f rom the data showed that several year classes such as the 1971 year class of cutthroat trout and the 1970 and 1971 year classes of brook trout, were numerically dominant in 1973 but not in 1974. When most of t he individuals in the last two year classes died via senescence in 1974 , the density and productive capacity of the brook trout population declined. This decline was a result of the failure of this taxa to produce new dominant year classes in 1973 and 1974. The periodic estimates from the data also showed that growth was similar in 1973 and 1974 except for the 0+ age group. The brown and cutthroat trout s of this age grew less in 1974 while the brook trout grew more. Immigration occurred seasonally with the adult cutthroat trout migrating in the spring, and the juvenile cutthroat and brown trout ~ ~oving in the fall. No precedent for the fall emmigration of cutthroat juveniles was found in the literature. Emigration was a random affair save for the 0+ age group of cutthroat trout. Migration of brook trout was ~ot significant. Production was greater in the growing season of 1973 than in 1974 for all species . During the year of trap operation only the 1974 year class of cutthroat trout and the 1970 year class of brown trout showed an increase in produced biomass. The failure of the brook trout to produce new dominant year classes was discussed and was attributed to the evacuation of beaver in Spawn Creek and the subsequent dilapidation of their ponds. The underestimation of the production of the 1974 year class of cutthroat trout and the probable causes for said error were discussed. The net emigration of juvenile cutthroat trout and the loss of produced biomass were tied together as a partial cause and effect. The failure of the net immigration of cutthroat trout adults to enhance the productive capacity of these year classes in this stream was attribut ed to reproductive activity and subsequent mortality of these individuals. This relationship along with the predominant emigration of cut throat juveniles showed Spawn Creek vis - a-vis this species to be primarily a vehicle to enhance the reproduction of migrants exclusive to any other activity by this species. The relationship among migration , production, and reproduction of brown trout appeared as described above for t he cutthroat trout , however, the small density of the population of this t rout prevented any firm illation.

This thesis examined the basic developmental concepts , space, quantity, time, miscellaneous, as they related to family size, sex, and rural-urban environment among kindergarten children. The Boehm Test of Basic Concepts was individually administered to 53 students from two kindergarten classes--one from Ogden City School District and one from Cache County School District. The findings indicated that family size, sex of the child, or urban-rural environment produced no significant differences in concept development among kindergarten children.

It has long been realized that the forests and forest products contributed very significantly toward the economic development of the Western United States. However, the extent of this contribution over a relatively small area has never been fully analyzed. Therein lies the primary justification for this paper. The author hopes that the readers of this paper will, through their reading, gain some appreciation of the major role the forest and its products played in the development of the western community.

During the period 1909-1949 many changes took place in agricultural production and cash farm income in Cache County, Utah, Important factors which caused changes in agricultural production and cash farm income during this period were technological developments in farm power and machinery, plant and animal breeding, changes in consumer demands price changes, and climatic conditions. The influence of these factors on both production and income varied with the enterprise, the commodity, and the year studied.
