Aspect] is a simple and practical aspect-oriented extension to Java With just a few new constructs, AspectJ provides support for modular implementation of a range of crosscutting concerns. In AspectJ's dynamic join point model, join points are well-defined points in the execution of the program; pointcuts are collections of join points; advice are special method-like constructs that can be attached to pointcuts; and aspects are modular units of crosscutting implementation, comprising pointcuts, advice, and ordinary Java member declarations. AspectJ code is compiled into standard Java bytecode. Simple extensions to existing Java development environments make it possible to browse the crosscutting structure of aspects in the same kind of way as one browses the inheritance structure of classes. Several examples show that AspectJ is powerful, and that programs written using it are easy to understand.

Constructivist Learning Environments: Case Studies in Instructional Design

In order to overcome the difficulty of password management and improve the usability of authentication systems, biometric authentication has been widely studied and has attracted special attention in both academia and industry. Many biometric authentication systems have been researched and developed, especially for mobile devices. However, the existing biometric authentication systems still have defects. Some biological features have not been deeply investigated. The existing systems could be vulnerable to attacks, such as replay attack and suffer from user privacy intrusion, which seriously hinder their wide acceptance by end users. The literature still lacks a thorough review on the recent advances of biometric authentication for the purpose of secure and privacy-preserving identification. In this paper, we classify and thoroughly review the existing biometric authentication systems by focusing on the security and privacy solutions. We analyze the threats of biometric authentication and propose a number of criteria with regard to secure and privacy-preserving authentication. We further review the existing works of biometric authentication by analyzing their differences and summarizing the advantages and disadvantages of each based on the proposed criteria. In particular, we discuss the problems of aliveness detection and privacy protection in biometric authentication. Based on our survey, we figure out a number of open research issues and further specify a number of significant research directions that are worth special efforts in future research.

A Participatory Programming Model for Democratizing Cobot Technology in Public and Industrial Fablabs

In this work we advance the understanding of software eco-systems research by examining the structure and evolution of the R statistical computing open-source ecosystem. Our research attempts to shed light on the following intriguing question: what makes software ecosystems successful? The approach we follow is to perform a quantitative analysis of the R ecosystem. R is a well-established and popular ecosystem, whose community and marketplace are steadily growing. We assess and quantify the ecosystem throughout its history, and derive metrics on its core software components, the marketplace as well as its community. We use our insights to make observations that are applicable to ecosystems in general, validate existing theories from the literature, and propose a predictive model for the evolution of software packages. Our results show that the success of the ecosystem relies on a strong commitment by a small core of users who support a large and growing community.

How do software ecosystems evolve? a quantitative assessment of the r ecosystem.

The ongoing development of collaborative robots (cobots) bears great potential for assembly processes by enabling new possibilities of task allocation between humans and machines. A detailed, empirically based evaluation of how cobots can live up to these possibilities in industrial practice is still missing in the manufacturing literature. In this paper some of the existing shortcomings -referred to as "the productivity gap" in current assembly automation processes are discussed. To cope with this gap, adaptive human-cobot task sharing is proposed and implemented as a complementary task allocation model. Its potential to increase productivity and flexibility in new and existing assembly applications is evaluated.

The Fukushima nuclear accident revived the question of whether current practices of technical communication can fulfill the needs of various audiences during a complex global crisis. In that context, the Institute of Nuclear Technology and Energy Systems in Stuttgart organized a public presentation on the technical aspects of the Fukushima nuclear accident. Its success indicates that direct encounter was preferred to media representations of the accident by Stuttgart's citizens. This event demonstrated that public presentation can provide a successful model for technical communication in situations of global sociotechnical crisis.
