Support for decision making on the World Wide Web : a thesis presented in partial fulfillment of the requirements for the degree of Masters of Information Science in Computer Science at Massey University, Turitea Campus, Palmerston North, New Zealand

This research explores tool support for information retrieval and comparison of multiple pieces of information on the web. The study identifies the main goals users may have in mind when using the Internet in this way, and the necessary activities users complete to fulfill their goals. The main goals web users have are information search, entertainment and consumer to business transactions. The tasks users perform on the web to fulfill their goals include collecting, comparing, filtering and processing web information. These tasks form a decision-making cycle on the web and depending on the goal at hand, users may or may not necessarily undertake all the tasks or sub-steps in any sequential order. Industry web support tools have been analyzed to find out how effective they are in supporting a common user's activities. These tools include web browsers (Netcaptor Browser and Internet Explorer), editing tools (Notes Pilot and Edit Pad), plug-ins, research tools and window management systems. Both browsers are poor at arranging multiple windows and excellent at opening web sites. The Internet Explorer browser proved to be better than the Netcaptor browser at a number of activities including, selecting web content, copying web text and images and pasting web content into editing documents. When used with either browser. Microsoft Windows is good for arranging windows but poor in switching windows views, scrolling windows and resizing and re-positioning windows. Both editing tools are poor at re-positioning and formatting web content from an HTML environment to a text-based environment. The Notes Pilot tool is also poor in making calculations and returning to the browser. It is excellent at saving work and retrieving old files. The Edit Pad tool is successful at all other activities except re-positioning and formatting web content. It can be seen that tool support is lacking or current web-based tools support the user poorly in a number of areas. The need for an integrated web support tool has been identified. The functional and non-functional requirements have been specified, the tool designed, implemented and evaluated by users. The users were requested to complete a questionnaire and conduct a think-aloud walk-through session while completing three tasks using the integrated web support tool. The sessions were observed and results recorded. Most of the users strongly agreed with the proposition that the tool would be useful for personal or academic activities. The users recognized the tool's novelty, its efficiency, and also indicated an overall level of satisfaction. The users were less satisfied about referring back to web sites, getting the software to do exactly what they wanted and arranging the work space to meet their needs. Changes were made to the tool

Pressure Ulcer Prevention System

Pressure ulcers, also known as bedsores, are a widespread but often understated problem. A pressure ulcer is an injury that develops with constant pressure on an area of skin for a long time. They range from bruises to open wounds to even exposed bone. These injuries especially impact bedridden and elderly hospital inpatients, since these people must depend on nursing staff for mobility. Pressure ulcers can seem to be a solved problem. Solutions that completely eliminate pressure ulcers do exist. These solutions, however, are too expensive for widespread use, at thousands of dollars per bed. Other solutions, such as relying on nursing staff to move all patients is not reliable, and nurses develop chronic back pain from the strain of moving so many patients so often. The Pressure Ulcer Prevention System is designed specifically to be an affordable solution for these injuries in a hospital or assisted living setting. The system collects data from a gyroscopic sensor and multiple pressure sensors mounted on the patient, and sends an alert to the nurses’ station if a patient is at risk of developing a pressure ulcer, and needs attending. The system does not replace nurse care, nor does it change the most common solution of manually moving patients, but it instead helps nursing staff be more efficient

The Invisible Forest: Conservation Easement Databases and the End of the Clandestine Conservation of Natural Lands

Olmsted talks about invisible forest refers to forest lands -- and, for that matter, any other land types -- protected by a perpetual conservation easement, the existence and location of which are concealed from the public, whether deliberately or because of the opaque nature of the easement process. Because easements, like other forms of deeds, must be recorded at the local land registry or recorder\u27s office, they can never be made undiscoverable. But, despite the efforts of some states and conservation organizations to compile conservation easement data for public consumption, there are few functional systems that comprehensively track and provide easy access to conservation easement data

Snowboard, Ski, and Skateboard Sensor System Application

The goal of this project was develop a sensor for the commercial market for skiers, snowboarders, and skateboarders that can give them the data such as speed, elevation, pressure, temperature, flex, acceleration, position, and other performance data such as trick characterization. This was done by using a variety of sensors, including a GPS, flex sensors, accelerometer, and others to provide data such as speed, position, position, and temperature. The sensors were placed in an external polycarbonate casing attached to the ski or board by using an adhesive pad on the bottom of the casing. These sensors then transmit the data via a microcontroller to either an LCD screen displaying a simple application or a memory system. The user can then access and analyze this data using Matlab code to interpret its relevancy. Using this system, performance data was recorded to analyze tricks such as spins and jumps

Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)

The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers

Real-time human action recognition on an embedded, reconfigurable video processing architecture

Copyright @ 2008 Springer-Verlag.In recent years, automatic human motion recognition has been widely researched within the computer vision and image processing communities. Here we propose a real-time embedded vision solution for human motion recognition implemented on a ubiquitous device. There are three main contributions in this paper. Firstly, we have developed a fast human motion recognition system with simple motion features and a linear Support Vector Machine (SVM) classifier. The method has been tested on a large, public human action dataset and achieved competitive performance for the temporal template (eg. “motion history image”) class of approaches. Secondly, we have developed a reconfigurable, FPGA based video processing architecture. One advantage of this architecture is that the system processing performance can be reconfiured for a particular application, with the addition of new or replicated processing cores. Finally, we have successfully implemented a human motion recognition system on this reconfigurable architecture. With a small number of human actions (hand gestures), this stand-alone system is performing reliably, with an 80% average recognition rate using limited training data. This type of system has applications in security systems, man-machine communications and intelligent environments.DTI and Broadcom Ltd
