SIMULATION OF A MULTIPROCESSOR COMPUTER SYSTEM

The introduction of computers and software engineering in telephone switching systems has dictated the need for powerful design aids for such complex systems. Among these design aids simulators - real-time environment simulators and flat-level simulators - have been found particularly useful in stored program controlled switching systems design and evaluation. However, both types of simulators suffer from certain disadvantages. An alternative methodology to the simulation of stored program controlled switching systems is proposed in this research. The methodology is based on the development of a process-based multilevel hierarchically structured software simulator. This methodology eliminates the disadvantages of environment and flat-level simulators. It enables the modelling of the system in a 1 to 1 transformation process retaining the sub-systems interfaces and, hence, making it easier to see the resemblance between the model and modelled system and to incorporate design modifications and/or additions in the simulator. This methodology has been applied in building a simulation package for the System X family of exchanges. The Processor Utility Sub-system used to control the exchanges is first simulated, verified and validated. The application sub-systems models are then added one level higher_, resulting in an open-ended simulator having sub-systems models at different levels of detail and capable of simulating any member of the System X family of exchanges. The viability of the methodology is demonstrated by conducting experiments to tune the real-time operating system and by simulating a particular exchange - The Digital Main Network Switching Centre - in order to determine its performance characteristics.The General Electric Company Ltd, GEC Hirst Research Cent, Wemble

Perceptions of Coding Instruction in K-12 Archdiocese of Los Angeles Catholic Schools

Traditional pedagogy offers students opportunities to enhance various skills and acquire content knowledge; however, additional steps can be taken to enhance student achievement, prepare them for future occupations, and bridge the divide in access to technology. A curriculum that integrates coding instruction affords students the opportunity to augment their collaboration, communication, creative thinking, and problem-solving skills. This is especially crucial for traditionally marginalized populations who have experienced inequitable access to technology. Nevertheless, coding is not integrated in schools in different domains, including Catholic institutions in the Archdiocese of Los Angeles (ADLA). This dissertation used a descriptive and inferential quantitative methodology to survey K–12 Catholic school teachers’, administrators’, and STEM directors’ understanding of what coding entails, assess their perceptions of coding’s potential to enrich student achievement, to prepare them for future occupations, and diversify STEM representation both in academics and in the workplace, and evaluate the potential link between educator epistemology and pedagogy with the penchant to incorporate coding instruction and the constructionist framework in the classroom. The largest diocese of the country, the ADLA, was the sole focus of this study and the data demonstrated participants have a relatively limited understanding of what coding entails, but they do believe it results in various benefits for students. Nevertheless, their epistemology and pedagogy are not ripe for constructionism to take hold in the classroom to facilitate coding
