In this course we will study techniques and algorithms for creating effective visualizations based on principles and techniques from graphic design, visual art, perceptual psychology and cognitive science.
It’s been a big year for tech policy books. Several important titles were released in 2008 that offer interesting perspectives about the future of the Internet and the impact digital technologies are having on our lives, culture, and economy.
xperience of practical systems modelling suggests that the key conceptual components of a model of a system are processes, resources, locations, and environment. In recent work, we have given a process- theoretic account of this view in which resources as well as processes are first-class citizens.
This paper explains how higher-order hierarchies can be used to handle the expression problem. The expression problem is concerned with extending both the set of data structures and the set of operations of a given abstract data type. A typical object-oriented design supports extending the set of data structures, and a typical functional design supports extending the set of operations, but it is hard to support both in a smooth manner. Higherorder
hierarchies is a feature of the highly unified, mixin-based, extension-oriented kind of inheritance which is available in the language gbeta, which is itself a language that was created by generalizing the language Beta.
I would like to elaborate on what theses challenges are and how the linker can be a serious trap for C++ developers. I learned it the hard way by spending hours and days on bug-hunting. Maybe this article will help others to avoid the frustration.
ecommr is a website showcasing the best (and sometimes worst) in e-commerce design, with a clear focus on the individual elements that make up online stores.
The paper is devoted to discussion of the inheritance relation on sets of Mealy automata. The concept of abstract data type (or, what is the same, of a class) is treated as an abstract automaton; relations of inheritance and polymorphism are introduced on sets of the Moore automata.
