    The development of an incremental debugging system : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University

    Debugging is a major area of software development that has received little attention. This thesis starts by looking at work done in the area of bug prevention, bug detection, bug location and bug correction. A debugging system, BIAS, is proposed to help in detecting, locating and correcting bugs. Three major design goals are established. Firstly, the system should be simple and easy to understand as this will encourage use. Secondly, the system should be general so that it will be available to a large number of users. Finally, it should be incremental as this will save users' time. An incremental language, STILL, is designed to show how BIAS applies to structured languages. The construction of the system is shown. Each data structure, and how it is used, is described. BIAS uses an interpretive system and runs threaded code on a pseudo-machine. How the threads are interpreted and how they are set up is shown next. The use of BIAS is shown by following through an example session with the system. This consists of entering a program, editing it, and running it. As bugs show themselves, various debugging commands are used to locate the bugs. The program is then edited, and the corrections linked into the code so that it will run correctly. This cycle is repeated until no bugs remain, without at any time recompiling the whole program. It turns out that the best way of achieving the design goals is to extend an incremental compiler host to include debugging commands. This gives a clear emphasis to the power of incremental compilers

    An investigation of pre-launch and in-flight STS range safety radio signal degradation and dropout

    Get PDF
    The range safety system (RSS) transmitters operate at a frequency of 416.500 MHz. The transmitting antennas transmit left circularly polarized waves, and the shuttle range safety system (SRSS) receiving antennas onboard the shuttle vehicle receive left circular polarization. Preliminary explanations are proposed for many of the observed fluctuations in signal levels. It is recommended that experiments and further investigation be performed to test the validity of certain of these explanations

    A study of radar cross section measurement techniques

    Get PDF
    Past, present, and proposed future technologies for the measurement of radar cross section were studied. The purpose was to determine which method(s) could most advantageously be implemented in the large microwave anechoic chamber facility which is operated at the antenna test range site. The progression toward performing radar cross section measurements of space vehicles with which the Orbital Maneuvering Vehicle will be called upon to rendezvous and dock is a natural outgrowth of previous work conducted in recent years of developing a high accuracy range and velocity sensing radar system. The radar system was designed to support the rendezvous and docking of the Orbital Maneuvering Vehicle with various other space vehicles. The measurement of radar cross sections of space vehicles will be necessary in order to plan properly for Orbital Maneuvering Vehicle rendezvous and docking assignments. The methods which were studied include: standard far-field measurements; reflector-type compact range measurements; lens-type compact range measurement; near field/far field transformations; and computer predictive modeling. The feasibility of each approach is examined

    The Woody Plants of Southeastern Iowa

    Get PDF
    This is a preliminary list of the species of trees and shrubs of southeastern Iowa, consisting of the counties of Davis, Des Moines, Henry, Jefferson, Keokuk, Lee, Louisa, Van Buren, Wapello, and Washington. The limits of the region were chosen for convenience in collecting and coincide fairly well with the forest belt of southeastern Iowa. The work at Parsons College as originally planned was to include all the above named counties, but extensive collecting has been done only in Jefferson and Van Buren Counties

    The theory and practice of marketing planning for industrial goods in international markets

    Get PDF
    This thesis identifies and evaluates the marketing-planning practices of British industrial goods companies operating internationally, and examines the validity of the widespread belief that formalised marketing planning facilitates success. Part I defines the theoretical framework for marketing planning and describes a logical sequence of activities leading to the setting of marketing objectives and the formulation of plans for achieving them. Part 2 contains detailed case histories describing the marketing planning practices of a sample of industrial goods companies. It also contains a summary of the results of in depth'interviews with 385 directors and senior managers from 199 companies covering a broad spectrum of size and diversity, the purpose of which was to establish the extent to which the theory is practised and what the consequences are of either conformity or non conformity. Part 3 contains conclusions and recommendations from the field- work, which revealed that 90 per cent of British industrial goods companies do not conform with the theory. This was universally true, irrespective of size and diversity. There was widespread ignorance about marketing and confusion about the difference between marketing planning and sales forecasting and budgeting, which encouraged operational managers to perpetuate an essentially parochial and short term view of business, and to extrapolate the business unchanged into the future. There was a commonality of operational problems in those companies not conforming with the theoretical framework, which centred around declining organisational effectiveness, and confusion over what to do about it. In contrast, those companies with complete marketing planning systems enjoyed high levels of organisational effectiveness, and a high degree of control over their environment. The major benefit of marketing planning derives from the process itself, rather than from the existence of a plan. This process is itself universal, irrespective of circumstances. However, what is not universal, is the degree of formalisation of the planning system, which is a function of company size-and the degree of product or market diversity. No marketing planning system will be complete unless the following conditions are satisfied: the chief executive has to understand the system and take an active part in it; there has to exist the means of integration with other functional areas'of the. business at general management level; in a closed loop system, some mechanism has to exist to prevent marketing inertia from over-bureaucratisation; operational and strategic marketing planning have to be part of the same system. Finally, the introduction of a complete marketing planning system may require a period of up to three years because it has profound organisational and phsychological ramifications, requiring, as it does, a change in the way a company manages its business

    The Distribution of Zooplankton in Lake Okoboji

    Get PDF
    During the past several summers a series of chemical and physical measurements have been made on Lake Okoboji by staff members of the Lakeside Laboratory. This is a continuation of work begun many years ago. In the summer of 1938 an attempt was made to study the relationship between the distribution of zooplankton and chemical and physical changes. During the period June 30 to August 24 collections were made every two or three days from two stations in West Okoboji and one in East Okoboji Lake. Each collection consisted of a series of ten-liter samples pumped from various depths, concentrated by passage through a plankton net, and preserved in formalin. Temperature, dissolved oxygen and other data were recorded at the same time. A complete count by species and age groups was made of each sample for all organisms except protozoa, which were ignored

    A Key to Species of Cyclops in Iowa

    Get PDF
    The genus Cyclops is one of the most common of the m1crocrustacea, and it occurs in almost every body of fresh water. Apparently because of this universality it has developed a wide variety of species and forms which are very difficult to distinguish from each other. For any study of ecological or geographical distribution of the genus, specimens must be identified as to species and subspecies. As an aid to such studies the following key has been compiled. This is not a field key in the sense that it can be used for field identification, but it will serve for identification without dissection of the animal, for the common species known to occur in Iowa
