Computer automation of ultrasonic testing

Report describes a prototype computer-automated ultrasonic system developed for the inspection of weldments. This system can be operated in three modes: manual, automatic, and computer-controlled. In the computer-controlled mode, the system will automatically acquire, process, analyze, store, and display ultrasonic inspection data in real-time. Flaw size (in cross-section), location (depth), and type (porosity-like or crack-like) can be automatically discerned and displayed. The results and pertinent parameters are recorded

The development and evaluation of computer generated material for 43.220 Information and Communications : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Technology - Information Engineering at Massey University

The information age is upon us. Technological advances, particularly in communications, have facilitated the conveyance of accurate and updatable information in vast quantities. Educational institutions have recognized the potential of such technology to increase the efficiency and effectiveness of their organizations. Institutions that depend almost entirely on technological knowledge transfer already exist and those who are not investigating how it may best be used in their university are likely to be left behind [1]. The impact of technology on education has been the subject of much speculation [2,3,4]. What is becoming apparent is that views of education are changing from that of 'option' to 'commodity' [5]. This has lead to an increasing demand for a varied education and an even greater burden for educators, given that there has been little change in the modes of delivery [1]. Therefore, in education, it has been argued that "more must be accomplished with less. Automation through the successful application of powerful new technologies is undoubtedly one of the key enablers" [6, p. 59). The Department of Production Technology at Massey University has been investigating how current technologies may best be utilized to facilitate multicampus teaching. Massey University, with its main campus at Palmerston North, now has a new campus situated approximately 600 kilometres north at Albany where the Department of Production Technology intends to offer one of its courses in the near future. Instead of duplicating many facilities, resources and staff at Albany an alternative is to have the courses remotely delivered. This has lead to the establishment of two systems whose objectives are to increase flexibility in delivery modes without decreasing the quality of education delivered

Distributed multimedia systems

A distributed multimedia system (DMS) is an integrated communication, computing, and information system that enables the processing, management, delivery, and presentation of synchronized multimedia information with quality-of-service guarantees. Multimedia information may include discrete media data, such as text, data, and images, and continuous media data, such as video and audio. Such a system enhances human communications by exploiting both visual and aural senses and provides the ultimate flexibility in work and entertainment, allowing one to collaborate with remote participants, view movies on demand, access on-line digital libraries from the desktop, and so forth. In this paper, we present a technical survey of a DMS. We give an overview of distributed multimedia systems, examine the fundamental concept of digital media, identify the applications, and survey the important enabling technologies.published_or_final_versio

High resolution, high frame rate video technology development plan and the near-term system conceptual design

The objective of the High Resolution, High Frame Rate Video Technology (HHVT) development effort is to provide technology advancements to remove constraints on the amount of high speed, detailed optical data recorded and transmitted for microgravity science and application experiments. These advancements will enable the development of video systems capable of high resolution, high frame rate video data recording, processing, and transmission. Techniques such as multichannel image scan, video parameter tradeoff, and the use of dual recording media were identified as methods of making the most efficient use of the near-term technology

An Automated System for Chromosome Analysis

The design, construction, and testing of a complete system to produce karyotypes and chromosome measurement data from human blood samples, and to provide a basis for statistical analysis of quantitative chromosome measurement data are described

An automated system for chromosome analysis. Volume 1: Goals, system design, and performance

The design, construction, and testing of a complete system to produce karyotypes and chromosome measurement data from human blood samples, and a basis for statistical analysis of quantitative chromosome measurement data is described. The prototype was assembled, tested, and evaluated on clinical material and thoroughly documented

Tangos: the agile numerical galaxy organization system

We present Tangos, a Python framework and web interface for database-driven analysis of numerical structure formation simulations. To understand the role that such a tool can play, consider constructing a history for the absolute magnitude of each galaxy within a simulation. The magnitudes must first be calculated for all halos at all timesteps and then linked using a merger tree; folding the required information into a final analysis can entail significant effort. Tangos is a generic solution to this information organization problem, aiming to free users from the details of data management. At the querying stage, our example of gathering properties over history is reduced to a few clicks or a simple, single-line Python command. The framework is highly extensible; in particular, users are expected to define their own properties which tangos will write into the database. A variety of parallelization options are available and the raw simulation data can be read using existing libraries such as pynbody or yt. Finally, tangos-based databases and analysis pipelines can easily be shared with collaborators or the broader community to ensure reproducibility. User documentation is provided separately.Comment: Clarified various points and further improved code performance; accepted for publication in ApJS. Tutorials (including video) at http://tiny.cc/tango
