Abstrac t . Electronic cash, and other cryptographic payment systems, offer a level of user anonymity during a purchase, in order to emulate electronically the properties of physical cash exchange. However, it has been noted that there are crime-prevention situations where anonymity of notes is undesirable; in addition there may be regulatory and legal constraints limiting anonymous transfer of...

The overall goal of the ongoing research described in this paper is to combine business management research in the domain of business models with more technical and conceptual research in the domain of informatics, particularly ontologies. In other words we aim at applying the rigor, precision, more complete descriptions (e.g. constraints and rules) and reasoning of ontologies to the concept of...

Security Requirements Engineering (SRE) deals with the specification of security requirements for the system-to-be starting with the analysis of security issues as soon as in the early requirements phase. STS-ml is an actorand goaloriented requirements modelling language for Socio-Technical Systems (STSs), which represents the security needs the stakeholders express as constraints over the inte...

Improving of the quality of the disc cutters’ plane layout design of the full-face rock tunnel boring machine (TBM) is the most effective way to improve the global performance of a TBM. The plane layout design of disc cutters contains multiple complex engineering technical requirements and belongs to a multi-objective optimization problem with multiple nonlinear constraints. Based on analysis o...

Distributed generation (DG) is rapidly increasing its penetration level in Australia, and is expected to play a more important role in the power industry. An important benefit of DG is its ability to defer transmission investments. In this paper, a simulation model is implemented to conduct quantitative analysis on the effect of DG on transmission investment deferral. The transmission expansion...

ing away from the particulars of the example, we now have three countercontexts to threaten the long-term efficacy of incentive programmes, namely: • (C1) budgetary constraints • (C2) alternative usage (exchange utility) • (C3) technical limitations on usage (durability etc.) The next task is to put this primitive little theory to work by considering further examples. Before we do so, it is use...

Demand for livestock products, including poultry, is expanding in West Africa as a result of population growth, increased urbanization, and rising incomes. Trade liberalization has had differing effects on poultry markets in the region, with some countries experiencing large import flows of frozen poultry from the European Union and others receiving very little. A 2005 analysis from the Pro-Poo...
