This paper describes using a mobile robot, equipped with some sonar sensors and an odometer, to test navigation through the use of a cognitive map. The robot explores an office environment, computes a cognitive map, which is a network of ASRs [36, 35], and attempts to find its way home.
Ten trials were conducted and the robot found its way home each time. From four random positions in two trials, the robot estimated the home position relative to its current position reasonably accurately.
Our robot does not solve the simultaneous localization and mapping problem and the map computed is fuzzy and inaccurate with much of the details missing.
In each homeward journey, it computes a new cognitive map of the same part of the environment, as seen from the perspective of the homeward journey. We show how the robot uses distance information from both maps to find its way home.

Abstraction is the most basic principle of software engineering. Abstractions are provided by models. Modeling and model transformation constitute the core of model-driven development. Models can be refined and finally be transformed into a technical implementation, i.e., a software system.
The aim of this book is to give an overview of the state of the art in model-driven software development. Achievements are considered from a conceptual point of view in the first part, while the second part describes technical advances and infrastructures. Finally, the third part summarizes experiences gained in actual projects employing model-driven development.
Beydeda, Book and Gruhn put together the results from leading researchers in this area, both from industry and academia. The result is a collection of papers which gives both researchers and graduate students a comprehensive overview of current research issues and industrial forefront practice, as promoted by OMG’s MDA initiative.
Institutional Ethnography
(2022)
Rehabilitation aims to enable people with disabilities or who are likely to experience disability to participate fully in their daily lives through a set of interprofessional and multimodal measures. Yet, rehabilitation services are embedded within social and healthcare systems that shape what individuals, who are active within these systems, can and may have to do. This chapter introduces Institutional Ethnography, a critical method of inquiry, which aims to explicate what people actually do and experience and how their doings and experiences become organized within textually mediated social relations. For rehabilitation practice and research, Institutional Ethnography is a powerful method to delineate which concepts are dominating institutional practices and to explicate whether these concepts are comprehensive enough to serve not only institutional purposes but account for and respond to the realities of people’s daily lives.
