An Integrated Structured Analysis Approach to Intelligent Agent Communication
- 1998
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Intelligent multi-agent systems offer promising approaches for knowledge-intensive distributed applications. Now that such systems are becoming applied on a wider industrial scale, there is a practical need for structured analysis and design methods, similarly as exist for more conventional information and knowledge systems. This is still lacking for intelligent agent software. In this paper, we describe how the process of agent communication specification can be carried out through a structured analysis approach. The structured analysis approach we propose is an integrated extension of the CommonKADS methodology, a widely used standard for knowledge analysis and systems development. Our approach is based on and illustrated by a large-scale multi-agent application for distributed energy load management in industries and households, called Homebots, which is discussed as an extensive industrial case study.

Pragmatics of Agent Communication
- 1998
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The process of agent communication modeling has not yet received much attention in the knowledge systems area. Conventional knowledge systems are rather simple with respect to their communication structure: often it is a straightforward question-and-answer sequence between system and end user. However, this is different in recent intelligent multi-agent systems. Therefore, agent communication aspects are now in need of a much more advanced treatment in knowledge management, acquisition and modeling. In general, a much better integration between the respective achievements of multi-agent and knowledge-based systems modeling is an important research goal. In this paper, we describe how agent communications can be specified as an extension of well-known knowledge modeling techniques. The emphasis is on showing how a structured process of communication requirements analysis proceeds, based on existing results from agent communication languages. The guidelines proposed are illustrated by and based on a large-scale industrial multi-agent application for distributed energy load management in industries and households, called Homebots. Homebots enable cost savings in energy consumption by coordinating their actions through an auction mechanism.

Lokalt utvecklingsarbete i Svarte, Ystad kommun : en utvärdering.
- 1998
-
Rapport (refereegranskat)abstract
- An evaluation of the local development work in Svarte, Ystad municipality, which has been carried on between 1995 and 1997. The evaluation aims to describe the local development work regarding 1)how the interplay between local and municipality actors has worked, 2)how local initiatives to development has been supported with municipal physical planning, 3)how civil ascendancy has come to expression, 4)how the collaboration within the municipality and between the municipality and other actors has worked, 5)how new forms of physical planning has been used.

Managing Large-Scale Computational Markets
- 1998
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- General equilibrium theory has been proposed for resource allocation in computational markets. The basic procedure is that agents submit bids and that a resource (re)allocation is performed when a set of prices (one for each commodity) is found such that supply meets demand for each commodity. For successful implementation of large markets based on general equilibrium theory, efficient algorithms for finding the equilibrium are required. We discuss some drawbacks of current algorithms for large scale equilibrium markets and present a novel distributed algorithm, CoTree, which deals with the most important problems. CoTree is communication sparse, fast in adapting to preference changes of a few agents, have minimal requirements on local data, and is easy to implement.

Scenario-based software architecture reengineering
- 1998
-
Konferensbidrag (refereegranskat)abstract
- This paper presents a method for reengineering software architectures. The method explicitly addresses the quality attributes of the software architecture. Assessment of quality attributes is performed primarily using scenarios. Design transformations are done to improve quality attributes that do not satisfy the requirements. Assessment and design transformation can be performed for several iterations until all requirements are met. To illustrate the method we use the reengineering of a prototypical measurement system into a domain-specific software architecture as an example.

Vem bestämmer : om medborgarinflytande och kommunal planering. Erfarenheter från Sydlänsprojektet.
- 1998
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Boverket och Folkrörelserådet Hela Sverige ska leva tog 1995 initiativ till Sydlänsprojektet. Syftet var att finna former för hur lokalt utvecklingsarbete kan få bättre stöd av kommunal planering men också hur medborgarinflytandet kan komma till tydligare uttryck. Denna rapport redovisar resultatet från utvärderingen av Sydlänsprojektet. Den innehåller iakttagelser och relexioner kring de processer som har ägt rum mellan nio kommuner och lika många lokala utvecklingsarbeten i deras försök att förbättra medborgarinflytandet i kommunal planering. Rapporten vänder sig till de personer som har varit involverade i Sydlänsprojektet men också till andra kommuner och grupper av medborgare som står i beredskap att starta eller befinner sig mitt i ett liknande arbete. Slutsatserna från utvärderingen och de förslag som presenteras bör även kunna tjäna som underlag för en allmän diskussion om hur medborgarnas delaktighet i samhällsplaneringen ska kunna förbättras. Det kan gälla förändringsarbte i såväl mindre samhällen som storskaliga bostadsområden. Erfarenheter från Sydlänsprojektet kan dessutom vara nyttiga för de personer som arbetar med att genomföra FN-initiativen Agenda 21 och Habitatagendan.

Radar-Like Measurements with an Experimental Digital Beamforming Array Antenna
- 1998
-
Konferensbidrag (refereegranskat)abstract
- An experimental S-band digital beamforming receiving array antenna has been used in “radar- like” measurements, where radar signals with programmable waveforms are transmitted. The measurements are carried out in an anechoic chamber and the measured signals come from the direct path from transmitter antennas to the receiver antenna. In this way targets are simulated. On the received signals, conventional beamforming, pulse compression, doppler filtering and high resolution direction of arrival estimation are performed. Accurate channel calibration and channel equalization are utilized. This paper first describes the receiving antenna, transmitter control, measurement arrangements, calibration and signal processing. It then presents some measurement results for high resolution direction of arrival estimation and for radar resolution of one and two targets.
