Arthemis: annotation software in an integrated capturing and analysis system for colonoscopy

Colonoscopy is an endoscopic technique that allows physicians to inspect the inside of the human colon. During a colonoscopic procedure, a tiny video camera at the tip of the endoscope generates a video signal of the internal mucosa of the colon. In current practice, the entire colonoscopic procedure is not routinely captured. Software tools providing easy access to important contents of videos that are digitally captured during colonoscopy are not available. Hence, it is very time consuming to review an entire video, locate important contents, annotate them, and extract the annotated contents for research, teaching, and training purposes. Arthemis, a software application, was developed to facilitate this process. For convenient data sharing, Arthemis allows annotation according to the European Gastrointestinal Society for Endoscopy (ESGE) Minimal Standard Terminology (MST), an internationally accepted standard for digestive endoscopy. Arthemis is part of our integrated capturing and content analysis system for colonoscopy called Endoscopic Multimedia Information System (EMIS). This paper presents Arthemis as a component of EMIS, the design and implementation of Arthemis, and key lessons learned from the development process.     

KMDS: an expert system for integrated hardware/software design ofmicroprocessor-based digital systems

A design automation system called KMDS, which makes use of a knowledge-based expert system and external algorithmic procedures to realize a modularized and flexible design automation tool, is presented. Its system configuration and characteristics, knowledge base and device libraries, top-down design methodology, and external utilities are described. Besides aiding the design of single-board microcomputers, KMDS helps designers of intelligence interface cards such as color display adapters and printer server cards. KMDS is flexible enough to incorporate various types of knowledge into the system and to overcome the problems that result from the existence of a large number of candidate solutions under a very high-level design specification. KMDS automatically generates a control program, making the fully automatic design of digital systems possible

RATMAC: A preprocessor for writing portable scientific software

In preparing a revision of XRAY, a large scientific crystallographic software package, it was decided to use a structured language as the primary coding language. RATFOR was chosen as the most appropriate preprocessor. Initial implementation experience showed that while RATFOR improved the quality of the coding it did little to ease the problems of portability. By augmenting RATFOR with a powerful macro processor, a versatile tool for generating portable scientific software was developed. The resulting preprocessor, RATMAC, is portable and can be optimized, via macros, to a local operating environment. Its characteristics, strengths and weaknesses are described.     

ESSE: an expert system for software evaluation

Solving software evaluation problems is a particularly difficult software engineering process and many different—often contradictory—criteria must be considered in order to reach a decision. This paper presents ESSE, a prototype expert system for software evaluation that embodies various aspects of the Multiple-Criteria Decision Aid (MCDA) methodology. Its main features are the flexibility in problem modeling and the built-in knowledge about software problem solving and software attribute assessment. Evaluation problems are modeled around top-level software attributes, such as quality and cost. Expert assistants guide the evaluator in feeding values to the decision model. ESSE covers all important dimensions of software evaluation through the integration of different technologies.

Metropolis: an integrated electronic system design environment

Today, the design chain lacks adequate support, with most system-level designers using a collection of unlinked tools. The implementation then proceeds with informal techniques involving numerous human-language interactions that create unnecessary and unwanted iterations among groups of designers in different companies or different divisions. The move toward programmable platforms shifts the design implementation task toward embedded software design. When embedded software reaches the complexity typical of today's designs, the risk that the software will not function correctly increases exponentially. The Metropolis project seeks to develop a unified framework that can cope with this challenge. Based on a metamodel with formal semantics that developers can use to capture designs, Metropolis provides an environment for complex electronic-system design that supports simulation, formal analysis, and synthesis.

Development toward an all-silicon integrated thermal management system: the integrated MCM

A new all-silicon multichip module with integrated thermal management system is presented. Our new packaging approach combines the benefits of wafer-scale integration with the flexibility of independently fabricated and pre-tested devices, allowing the development of highly integrated systems. Wet anisotropic etching is used for the dicing of silicon integrated circuits as well as for the fabrication of the chip-receiving cavities in the silicon substrate. The etching exposes {1 1 1} type planes in both chip and receiving surface, assuring a virtually perfect mating of the assemblage. The system is complemented with an integrated silicon heat sink, which can maintain heat fluxes in excess of 100 W/cm².     

Supporting software quality in an integrated safety-critical systems development environment

Research is described, aimed to support traceability in the design of software for safety-critical applications, through the provision of an on-line design journal enabling design decisions and actions to be traced and recorded. The design environment, within which various software design tools may be encapsulated, enables protocol between the user and the design tools to be trapped. This provides software engineering support at the conceptual design stage. An important aim of the research is to enable inferences to be made from the captured protocol, for which the application of artificial intelligence methods is being investigated.     

AspectC++: An integrated approach for static and dynamic adaptation of system software

Modern computer systems require an enormous amount of flexibility. This is especially the case in low-level system software, from embedded devices to networking services. From literature and practice, various approaches to modularize and integrate adaptations have been investigated. However, most of this work is implemented with dynamic languages that offer extensive run-time support and enable easy integration of such approaches. System software is written in languages like C or C++ in order to minimize utilization of system resources and maximize efficiency. While for these languages highly optimized and reliable compilers are available, the support for static and dynamic adaptation is rather limited. In order to overcome these limitations, we present an adaptation approach that is based on a sophisticated combination of static and dynamic aspect weaving for aspects written in AspectC++. This facilitates the incremental evolution and deployment of system software that has to be “always on”. We demonstrate the feasibility of our approach and its applicability to two pieces of system software, namely the Squid web proxy and the eCos operating system, which is used in the domain of resource-constrained deeply embedded systems.     

MIL project: a microcomputer integrated laboratory

The introduction of microprocessors has meant a tremendous change in electronic technology and it is a common feeling that, with the continuous improvement of LSI and VLSI technology, the future will evolve at least at the same rate. This revolution produced great changes not only in electronic products themselves, but deeply affected research laboratories, production plants and maintenance services of all industries manufacturing electronic equipment or incorporating electronics in their final products. The main effect was a great demand for people with knowledge coming from different and previously separated fields: computer science, software engineering and digital electronic design. The first answer to the need of a quick updating for designers came from the market itself and everyone knows how many one-day courses were offered on ‘everything you must know about microprocessors’. A more long-term answer is the responsibility of the universities and of the technical schools that must prepare the new people for the new technological wave.
