This article presents a critical review of patterns and pattern languages in human-computer
interaction (HCI). In recent years, patterns and pattern languages have received …

AspectJ implementations of the GoF design patterns show modularity improvements in 17 of
23 cases. These improvements are manifested in terms of better code locality, reusability …

We study the quality of service (QoS) of failure detectors. By QoS, we mean a specification
that quantifies 1) how fast the failure detector detects actual failures and 2) how well it avoids …

Software pattern designers and users have few resources available to support pattern-
based development practices. Patterns are currently disseminated in disjoint collections in …

Informally described design patterns are useful for communicating proven solutions for
recurring design problems to developers, but they cannot be used as compliance points …

Micro patterns are similar to design patterns, except that micro patterns are stand at a lower,
closer to the implementation, level of abstraction. Micro patterns are also unique in that they …

The terms architecture, design, and implementation are typically used informally in
partitioning software specifications into three coarse strata of abstraction. Yet these strata …

Software experts agree: the most difficult aspect of building software is not coding; it is the
decisions the designer makes in the early stages. Those decisions live with the system for …

Pattern users are faced with difficulties in understanding when and how to use the
increasing number of available design patterns. This is mainly due to the inherent ambiguity …

Abstract Design Patterns are now widely accepted as a useful concept for guiding and
documenting the design of object-oriented software systems. Still the UML is ill-equipped for …
