Health Care Systems Modelling at IIASA: A Status Report

The focus of the Human Settlements and Services Area at. IIASA is people -- their number and geographical distribution, their needs and demands for resources and services, and their impact on the environment. Research in the Area is divided into three themes: urban systems management, human resources and services, and human settlement systems. This report describes work that has been carried out up to the Fall of 1978 by the Health Care Systems , Modeling Task, representing the human resources and services theme. It focuses in particular on the submodels that have been developed and tested, and on the collaboration that has been established with similar research teams in a number of countries around the world. Governmental policies in all countries strongly influence the medical services available to society. It is therefore essential that decisionmakers be aware of changing demands and needs for health resources and services. In the light of this, the HCS Modeling Task has set a goal of creating a model that will assist national decisionmakers in their policy formation. This model consists of a number of linked submodels dealing with various related topics from population growth to resource allocation. . Some of these submodels have already been tested, and collaborating national research centers have started to implement them with their own data. The resulting experience of the past several years is described in this review prepared by members of the HCS Modeling group. By sharing our aims and achievements with a wider audience, we hope to facilitate future international collaborative work on this research

Developing a methodology for integration of Whole Life Costs into BIM processes to assist design decision making

A growing body of evidence suggests that the most common barrier to achieving design intent is the absence of comprehensive information during design development, leading to poor decision-making which impacts on actual building performance, and thus Whole Life Cost (WLC). Building Information Modeling (BIM) has the potential to facilitate a more comprehensive and accurate design approach from the early stages. A detailed model can allow designers and clients to understand the wider impacts of design changes, and to track this information through construction stages. However, dependencies between design decisions and WLC have yet to be understood. This paper is based on a project that focuses on the Private Rental Sector (PRS), which is the fastest growing new sector in the UK housing market. The study adopts a mixed method approach for the development and validation of a structured standardised process for timely WLC estimation through BIM. As a result, the main problems in WLC BIM management are identified, and coordinated into a reverse-engineered systematic process that uses the Integrated DEFinition (IDEF) 3 structured diagramming modeling technique. The research outputs aim to enhance BIM lifecycle management through a smart decision-making approach that is integral to the natural design development process

Actuators and sensors for application in agricultural robots: A review

In recent years, with the rapid development of science and technology, agricultural robots have gradually begun to replace humans, to complete various agricultural operations, changing traditional agricultural production methods. Not only is the labor input reduced, but also the production efficiency can be improved, which invariably contributes to the development of smart agriculture. This paper reviews the core technologies used for agricultural robots in non-structural environments. In addition, we review the technological progress of drive systems, control strategies, end-effectors, robotic arms, environmental perception, and other related systems. This research shows that in a non-structured agricultural environment, using cameras and light detection and ranging (LiDAR), as well as ultrasonic and satellite navigation equipment, and by integrating sensing, transmission, control, and operation, different types of actuators can be innovatively designed and developed to drive the advance of agricultural robots, to meet the delicate and complex requirements of agricultural products as operational objects, such that better productivity and standardization of agriculture can be achieved. In summary, agricultural production is developing toward a data-driven, standardized, and unmanned approach, with smart agriculture supported by actuator-driven-based agricultural robots. This paper concludes with a summary of the main existing technologies and challenges in the development of actuators for applications in agricultural robots, and the outlook regarding the primary development directions of agricultural robots in the near future

Design rules and guidelines for generic condition-based maintenance software's Graphic User Interface

The task of selecting and developing a method of Human Computer Interaction (HCI) for a Condition Based Maintenance (CBM) system, is investigated in this thesis. Efficiently and accurately communicating machinery health information extracted from Condition Monitoring (CM) equipment, to aid and assist plant and machinery maintenance decisions, is the crux of the problem being researched. Challenges facing this research include: the multitude of different CM techniques, developed for measuring different component and machinery condition parameters; the multitude of different methods of HCI; and the multitude of different ways of communicating machinery health conditions to CBM practitioners. Each challenge will be considered whilst pursuing the objective of identifying a generic set of design and development principles, applicable to the design and development of a CBM system's Human Machine Interface (HMI).

Dynamic throughput in distributed multimedia

Personal computing is currently undergoing radical enhancements with the current technological advancements that have been made in the areas of high resolution displays, GUIs (graphic user interfaces), high quality sound and full motion video. Multimedia stands at the convergence of these technological advances. The pervasiveness of networks will result in a new generation of distributed services that include multimedia as the fundamental characteristic. The current hyper-activity in the commercial arena is testimony to the future of distributed mu1timedia services. The anticipation of the data superhighways has led to an industrial scramble filled with takeovers and acquisitions as companies battle to acquire the infrastructure that will set the scene for the services of the future.

Software metrics for monitoring software engineering projects

As part of the undergraduate course offered by Edith Cowan University, the Department of Computer Science has (as part of a year\u27s study) a software engineering group project. The structure of this project was divided into two units, Software Engineering l and Software Engineering 2. ln Software Engineering 1, students were given the group project where they had to complete and submit the Functional Requirement and Detail System Design documentation. In Software Engineering 2, students commenced with the implementation of the software, testing and documentation. The software was then submitted for assessment and presented to the client. To aid the students with the development of the software, the department had adopted EXECOM\u27s APT methodology as its standard guideline. Furthermore, the students were divided into groups of 4 to 5, each group working on the same problem. A staff adviser was assigned to each project group. The purpose of this research exercise was to fulfil two objectives. The first objective was to ascertain whether there is a need to improve the final year software engineering project for future students by enhancing any aspect that may be regarded as deficient. The second objective was to ascertain the factors that have the most impact on the quality of the delivered software. The quality of the delivered software was measured using a variety of software metrics. Measurement of software has mostly been ignored until recently or used without true understanding of its purpose. A subsidiary objective was to gain an understanding of the worth of software measurement in the student environment One of the conclusions derived from the study suggests that teams who spent more time on software design and testing, tended to produce better quality software with less defects. The study also showed that adherence to the APT methodology led to the project being on schedule and general team satisfaction with the project management. One of the recommendations made to the project co-ordinator was that staff advisers should have sufficient knowledge of the software engineering process
