Micropayment business in Finland- forming the basis for development of micropayment methods and business

Micropayments provide companies and individual persons a way to obtain potentially a great deal of revenue for the digital content (such as music, games). At the moment lot ofdigital content is either not provided at all or is provided for free. The micropayment business has a great revenue potential in future. So far only few companies have managed to reach considerable success. Mobile test bed countries such as Finland have the entire infrastructureneeded in micropayments and a very high utilization rate of Internet and mobile phones. Despite of this, micropayments are not very popular. The purpose of this paper is twofold. First it aims at discovering and comparing different micropayment methods proposed. Second, it outlines the current status in Finland and proposes avenues that should be taken in order to make the micropayment business more attractive and profitable

Managing software development information in global configuration management activities

Software Configuration Management (SCM) techniques have been considered the entry point to rigorous software engineering, where multiple organizations cooperate in a decentralized mode to save resources, ensure the quality of the diversity of software products, and manage corporate information to get a better return of investment. The incessant trend of Global Software Development (GSD) and the complexity of implementing a correct SCM solution grow not only because of the changing circumstances, but also because of the interactions and the forces related to GSD activities. This paper addresses the role SCM plays in the development of commercial products and systems, and introduces a SCM reference model to describe the relationships between the different technical, organizational, and product concerns any software development company should support in the global market

Clonal analysis reveals multiple functional defects of aged murine hematopoietic stem cells

As shown using clonal assays, the mouse HSC population undergoes quantitative as well as qualitative changes with age, including lineage differentiation, HSC pool size, marrow-homing efficiency, and self-renewal

Variability engineering as an integral part of the software product family development process

Alhoewel het vrijwel onmogelijk is om het belang van software in het dagelijks leven te overschatten worden de mogelijkheden van sofware over het algemeen net volledig benut. Software eningeering verschilt van ingenieurdisciplines zoals elektrotechniek en werkbouwtuigkunde vanwege de fexilbiliteit die inherent is aan het concept software. ... Zie: Samenvatting

Product families on-chip:Combining the software product family paradigm with run-time reprogrammable hardware technology

Hardware and software can be co-designed as a single system to obtain high-performance computing solutions that use a minimum of resources such as CPU cycles and memory. Hardware/software co-design is often a complex and time consuming process. Software functionality is typically developed independently from hardware functionality and functional elements are not reused across similar products. Co-design is particularly important in System on-Chip (SoC) development where an entire system consisting of both software and hardware is integrated on a single chip. Developing high-performance computing solutions in the form of SoCs in a repeatable manner is technically possible, but knowing how to apply software concepts in a hardware context and vice versa is still demanding at best. This paper summarizes the concepts and considerations that outline a case study that aims at combining the software product family paradigm with run-time reprogrammable hardware technology. The goal of the study is to define a formal framework for developing product families on-chip in a repeatable manner
