In Geng, Weiss, and Wol (2011), we pointed to the possibility that a voting mechanism may create or strengthen an entitlement e ect in political-power holders relative to a random-appointment mechanism. This comment documents that such an e ect, if it exists, is not robust.

An alternate approach to emergency risk minimization, based on lazy calculations and high-level functional interpretation is presented in this article. This approach is compared with classical imperative approach, based on statistical analysis on real data in order to prove its effectiveness.

This paper describes a naturalistic approach to the development of a large-scale, functional, cognitively plausible model of language comprehension, and contrasts the approach with mainstream cognitive modeling and computational linguistic research. An approach to research is described which accepts the theoretical constraints of a cognitive architecture, while replacing the fine-grained empiri...

In this paper we introduce the representative object, which uncovers the inherent schema(s) in semistructured, hierarchical data sources and provides a concise description of the structure of the data. Semistructured data, unlike data stored in typical relational or object-oriented databases, does not have fixed schema that is known in advance and stored separately from the data. With the rapid...

We propose a pattern-based software development method comprising analysis (using problem frames) and design (using architectural and design patterns), from which especially evolving systems benefit. Evolution operators guide a pattern-based transformation procedure, including re-engineering tasks for adjusting a given software architecture to meet new system demands. Through application of the...

This paper briefly describes the most relevant current approaches to the implementation of scientific models of consciousness. Main aspects of scientific theories of consciousness are characterized in sight of their possible mapping into artificial implementations. These implementations are analyzed both theoretically and functionally. Also, a novel pragmatic functional approach to machine cons...

Obstacle Avoidance for a Mobile Robot A notorious problem in mobile obstacle avoidance is the detection and avoidance of obstacles. This thesis evaluates several well-known methods for controlling the motion of a mobile robot in an unknown dynamic environment. One of these methods, the Global Dynamic Window Approach, is selected and, using a laser range finder as the only range sensor, the meth...

A general account is given of the problem frames approach to the development of software-intensive systems, assuming that the reader is already familiar with its basic ideas. The approach is considered in the light of the long-standing aspiration of software developers to merit a place among practitioners of the established branches of engineering. Some of its principles are examined, and some ...

We present the local path planning and obstacle avoidance method used on the autonomous tour-guide robot RoboX. It has proven its value during a 5 month operation of ten such robots in a real-world application, a very crowded exhibition. Three known approaches (DWA, elastic band, NF1) have been integrated into a system that performs smooth motion efficiently, in the sense of computational effor...
