Finally the utility should be able to update the server with the choices of the user.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / There is a continuing need in the aerospace industry for lower cost and more maintainable telemetry data processing systems that can deliver a high level of performance. While systems based on the Intel family of x86 processors and Microsoft operating systems have seen increasing use in lower performance and portable applications, UNIX/VME based systems have been necessary to achieve required performance in higher end, multi-stream applications. Recent developments in the computer industry now promise lower cost alternative to these systems. With currently available technology, it is now possible to provide a powerful distributed processor architecture based entirely on commercial products. The system takes advantage of the latest of Intel Pentium processors, the PCI bus, 100BaseT Fast Ethernet, Microsoft Windows NT, ActiveX technology and NT servers. The architecture offers both current and future cost advantages for test facilities which must support a diverse set of requirements and which must maintain and support systems for many years.

International Telemetering Conference Proceedings / October 27-30, 1997 / Riviera Hotel and Convention Center, Las Vegas, Nevada / There is a wave of change coming. It started in the industrial automation community and it is slowly and surely working its way into aerospace, satellite and telemetry applications. It’s called the PC, and its not just for simple quick-look data anymore. Using state-of-the-art commercial hardware and software technologies, PC-based architectures can now be used to perform self contained, reliable and high performance telemetry data acquisition and processing functions – previously the domain of expensive, dedicated front end systems. This paper will discuss many of the key enabling technologies and will provide examples of their use in a truly next generation system architecture based on the Microsoft® Windows NT Operating System and related features.

This thesis assesses the potential of using computer simulation to aid existing lean manufacturing training methods such as lecture and live simulation. An investigation of this possibility was carried out in conjunction with UMEP's Lean 101 class. In the study, two experimental computer simulation models demonstrating the push and pull production scenarios were constructed using ProModel software. Simulation models were equipped with a Visual Basic interface to aid trainees to manipulate the model via ActiveX. Constructed computer simulation was compared with live simulation to answer these research questions: 1. Was computer simulation able to teach additional lean concepts not covered in live simulations? 2. Was training time less for trainees going through a computer simulation than for those going through a live simulation? 3. Was a computer simulation quicker and easier to set up than a live simulation for trainers? 4. Did computer simulation achieve comparable educational objectives as live simulation? Objective measurements for first three questions were positive and conclusive. For the fourth one, a survey was conducted among trainees of a treatment group (computer simulation only) and a control group (live simulation only) to collect responses. Statistical analysis of the subjective responses indicated the computer simulation aided the trainees to learn and implement lean manufacturing, but was not as effective as live simulation. Holistically, these results did not warrant the complete changeover from live simulation to computer simulation. Yet, a combined implementation of computer simulation and live simulation was proposed to reap the benefits from the best of both approaches.

For many years it has only been HTML, CSS, and JavaScript that have been native to the Web. In December 2019, WebAssembly joined them as the fourth language to run natively on the Web. This thesis compared WebAssembly to the technologies ActiveX, Java applets, Asm.js, and Portable Native Client (PNaCl) in terms of their performance, security, and browser support. The reason why this was an interesting topic to investigate was to determine in what areas WebAssembly is an improvement over previous similar technologies. Another goal was to provide companies that still use older technologies with an indication as to whether or not it is worth upgrading their system with newer technology. To answer the problem, the thesis mainly focused on comparing the performance of the technologies through a controlled experiment. The thesis also aimed at getting a glimpse of the security differences between the technologies by the use of a literature study. The thesis showed that PNaCl was the technology with the best performance. However, WebAssembly had better browser support. Also, PNaCl is deprecated while WebAssembly is heavily supported and could potentially be further optimized.

小型化革命已經造成了企業資訊系統的典範轉移，不久之前以大型主機為基礎的集中架構仍然是企業之重要資訊系統的唯一選擇，時至今日為數眾多的重要企業資訊系統採用了以個人運算裝置為基礎的主從架構。另外一方面，視窗主從企業資訊系統是目前最常見的主從架構企業資訊系統類型，此類企業資訊系統必需將每一支客戶端程式都安裝到每一位使用者的電腦上，這種客戶端程式的人工部署作業一直是資訊管理從業人員的沈重負擔，亦是資訊管理產學界持續戮力解決的重要研究課題。其實ActiveX元件技術的妥善應用將可以有效解決這個部署問題，並且這種解決方案將遠比其它解決方案更具成本效益。研究以此發現為基礎，目的在於克服ActiveX元件技術在企業資訊系統應用上一直無法解決的三項缺點：能力強大所衍生的不安全、技術龐雜所衍生的學習與使用困難，以及元件體積龐大所衍生的網路應用瓶頸，並提出一個以ActiveX元件為基礎的解決方案來自動化暨有之視窗主從企業資訊系統的客戶端程式部署作業。報告的重點內容有四：(一)ActiveX元件技術的缺點克服之道；(二) 所提解決方案的第一個部份，也就是下載架構，採用下載架構開發的企業資訊系統將具備自動化部署客戶端程式的特性；(三)所提解決方案的第二個部份，也就是架構轉換程序，藉由這個程序的指引，暨有的視窗主從企業資訊系統將可以輕鬆轉換成為下載架構，有效解決其客戶端程式的部署問題；(四)兩個研究個案，用來示範下載架構與架構轉換程序的使用，並提供證據來支持下載架構與架構轉換程序的可行性。 / The downsizing revolution has created a deep paradigmatic shift in business information systems (BISs). Not very long ago, large-scale mission-critical BISs were the exclusive province of massive mainframe computers. That is changing rapidly. Today, increasingly large and complex BISs are being built as client/server (C/S) applications. Unfortunately, for the most common C/S BISs, that is, the Windows-based C/S BISs (WinBISs), client programs must be manually deployed to each end-user machine bringing about a heavy BIS maintenance load. ActiveX component technology, if used properly, is more cost-effective than other alternatives in improving the deployment of existing WinBISs. Nevertheless, ActiveX component technology is no magic solution, and thus still has three shortcomings, namely insecurity, complexity, and bulkiness. The purpose of the study presented in this paper is to overcome the shortcomings of ActiveX component technology, and then develop an ActiveX component-based solution to automate the deployment of existing WinBISs. This paper has four main parts: (a) the answers to the shortcomings of ActiveX component technology; (b) the downloadable architecture, which supports the development of automatically-deployed BISs; (c) the architecture transformation process, which transforms existing WinBISs into the downloadable architecture; and (d) two examples of how to use the downloadable architecture and the architecture transformation process. The examples also provide evidence to support the feasibility of such architecture and process.
