The design and implementation of a remote terminal monitorReid, William 11 April 2014 (has links)
This thesis describes the design and the implementation of a monitor for low-speed remote terminals. The basic features of the monitor are:
-terminal users have access to a library of programs,
-all communication with the terminals is handled by the monitor,
-any program executing in the computer can communicate with a terminal via the monitor,
-programs which are communicating with the terminals are transferred to backing storage
when they are not active. This allows different programs to use the same memory area during their execution.

Avbrottsstyrd hexkodsmonitor : Programmering av MikroprocessorPhilips LPC2292Erkers, Anders January 2007 (has links)
Research Elektronics är ett företag som utvecklar elektroniska system. I sinalösningar använder de bl.a. Siemens C500 Mikroprocessorer. Företagetplanerar nu att gå över till Philips LPC 2292 som bygger på en 32-bitarsARM-kärna. Denna mikroprocessor har högre prestanda och är merkostnadseffektiv.Uppgiften bestod av att göra ett monitorprogram som bl.a. kan ladda in ochköra andra program i mikroprocessorn samt undersöka och redigerainnehållet i minnen och register. Programmet ska användas till test ochutveckling av andra program till den aktuella mikroprocessorn. Tanken meddenna monitor är att den ska ha liknande funktion och utseendet som enmonitor som Research redan använder för mikroprocessorn Siemens c500serie, för att dessa ska kunna gå över till att använda den nyamikroprocessorn på samma sätt som den nuvarande.Tanken med programmet är att det ska vara en grund som Research senareska kunna modifiera och utveckla under deras arbete. Programmet harskrivits i assembler för att programmera nära hårdvaran. Resultatet blev ettprogram med de funktioner som i förväg var bestämda.

The design and application of microprocessor based systems for clinical measurement of joint stiffness and grip strengthBromley, John January 1989 (has links)
The overall aim of the project was to further the research into the objective measurement of the symptoms of arthritic disease. There were three major parts to this study. The first part was to design a measurement system capable of making large scale, objective measurements of the stiffness of the human metacarpophalangeal joint. The second part was to design a new device to measure the grip strength of the human hand objectively. The last part was to use these two measurement systems to conduct research into the clinical manifestations of arthritic disease and study the effects of some therapeutic agents. A new, microcomputer controlled arthrograph system was developed to measure the stiffness of the metacarpophalangeal joint of the index finger. The system proved to be reliable, easy to use and sufficiently accurate to quantify changes in joint stiffness. A new design of grip machine was produced which enabled the forces developed during a power grip to be analysed. Measurement was made of the force contributions of individual digits and the maximum total gripping force. The machine was portable and extremely easy to use. A study of the circadian variation of joint stiffness and grip strength, over a full twenty four hour period, was carried out. Measurements were made every two hour in both healthy and arthritic subjects. A circadian variation of stiffness was observed in the joints of arthritic subjects. Joint stiffness was elevated in the early morning and for some subjects the degree of change was profound. No significant circadian variation was observed in the joint stiffness of healthy subjects. A circadian variation of grip strength was observed in arthritic subjects. Grip strength reached a minimum value between 2.00 and 4.00 a.m. in the majority of subjects. No consistent relationship was found between changes in joint stiffness and changes in grip strength. The effect of several forms of physiotherapy on the joint stiffness of arthritic subjects was studied in both the short and long term. The subjects were measured before, and then immediately after, treatment each time they visited a physiotherapy hand clinic. Only the results of those patients who attended the clinic for a minimum of five weeks were used in any subsequent analysis. Four different treatments were studied: hot wax and ultrasound, hot wax alone, ultrasound alone and exercise. The combination of hot wax baths and ultrasonic therapy effected temporary reductions in all joint stiffness parameters. The reductions in energy dissipation and torque range were highly significant ( p < 0.05 and p < 0.001 respectively ). No significant reductions were found for hot wax, ultrasound alone or exercise. In the long term, no significant change in joint stiffness was found for any of the treatments considered.

Evolution of locomotion in Australian Varanid lizards (Reptilia: Squamata: Varanidae) : ecomorphological and ecophysiological considerationsClemente, Christofer January 2006 (has links)
[Truncated abstract] In ecomorphological or ecophysiological studies, variation in `design? traits (e.g. size, morphology and physiology) is thought to determine variation in ecologically-relevant performance traits, which in turn determines fitness in a particular habitat (Arnold 1983). Thus, natural selection is thought to act most directly on intermediate traits such as measures of locomotory performance. This thesis examined this process in the closely related group of Australian varanids lizards (Squamata: Varanidae). Phylogenetically, varanids are divided into three major clades. Size (mass and snout-to-vent length) is strongly correlated with these three clades. Two clades, (Gouldii and Komodoensis) are large, while the third clade (Odatria) has a smaller body size. Thus, there is considerable variation in size for various species. Size varied for species by three orders of magnitude. Size is also related to two ecological characteristics, foraging mode and habitat openness. Widely-foraging species were larger than sit-and-wait strategists, while species from open habitats were larger than species from semi-open or closed habitats. However, given the tight link between size and phylogeny we cannot separate adaptation of size to ecological traits from that of phylogenetic patterns. Of interest throughout this thesis was how variations in design (e.g. morphology and physiology) were related to ecological characteristics. Since body size also influences many of these morphological and physiological characteristics it is often necessary to remove the effects of size. Three design traits were examined in detail: body dimensions, vertebral number and metabolic rates. …Curiously, no performance variable linked differences in size-free body dimensions to retreat sites. This suggests that there is either a direct link between design and ecology (e.g. dorso-ventral compression), or some unmeasured performance variable related to retreat site. Given that most performance traits are thought to involve kinematic movements of the hindlimb limb and pelvis, and these were not best related to retreat site, then a direct link between design and ecology with respect to retreat site seems possible. In summary, this thesis provides evidence not only for links between design and ecology mediated by locomotory performance traits, but also direct links between design and ecology, for Australian varanid lizards.

Synthesis and evaluation of a monitoring and control system for a neutron monitor / Renier FuchsFuchs, Renier January 2014 (has links)
Neutron monitors detect secondary particles produced by the collision of cosmic rays and atmospheric nuclei. The need exists for a mini-neutron monitor data acquisition system (MNM-DAS) to replace the existing recording system of the calibration neutron monitor developed in 2003 at the North-West University Centre for Space Research. The MNM-DAS must also replace the recording system of a standard NM64 neutron monitor.
This research thus includes the development of the MNM-DAS using Design Science Research (DSR) in conjunction with Systems Engineering (SE) to streamline the design phase and maximize research output. A literature study is conducted, where an overview of the calibration monitor system is provided, together with the objectives for the development of the MNM system.
An abstract system architecture was drawn up in the conceptual design phase of the project to provide a coherent description of all system functions. The system architecture was derived for the existing system, including additional functions of the required system, by performing a functional analysis. The architecture describes the function and fit of each functional unit and all interfaces that form an integrated system.
From the conceptual design and system architecture, a preliminary synthesis was done. Following the preliminary synthesis, electronic circuitry was developed to capture the arrival time of pulses from the proportional neutron monitor counter tubes along with environmental variables, such as temperature, pressure, and location, which all influence the count rate.
The MNM-DAS was successfully designed and developed by following this Systems-Engineering approach embedded into a Design Science Research framework. The MNM-DAS was constructed and tested, and is currently being used to provide neutron count data in real-world applications internationally. / MIng (Computer and Electronic Engineering), North-West University, Potchefstroom Campus, 2014
