VarietyCash is a new electronic money system which strikes a balance between functionality, security, and user privacy. The system can encompass both network and stored-value card based payment mechanisms, with transferability between them, hence the name.

Traditional concepts of managing product innovation are not suitable for innovation in complex product systems (CPSs). This paper argues that firms developing and integrating the components of CPSs need specific competence for managing such projects. A framework for evaluating a firm’s competence in CPS innovation is developed that covers managing the integration of internal and external key re...

Let L → H be a lattice homomorphism and let a “readable” drawing of H be given. It is natural to make use of it to try getting a clear(er) drawing of L. Hence, the following question is explored: How the knowledge of the congruence lattice Con(L) of L can help in getting “better” drawings of L? This will be done by proposing rank shelling procedures of (M(Con(L),≤) and will be illustrated with ...

The forward pick area of a distribution center is a cache of conveniently located products from which order pickers can quickly draw, but which must be replenished from bulk or reserve storage. The quantities stored forward determine the amount of work required to sustain the forward pick area. Two stocking strategies that are commonly used in industry are analyzed and compared with the optimal...

Machines would be more useful if they could learn to perform tasks for which they were not given precise methods. Difficulties that attend giving a machine this ability are discussed. It i s proposed that the program of a stored-program computer be gradually improved by a learning procedure which tries many programs and chooses, from the instructions that may occupy a given location, the one mo...

This technical note provides an introduction to writing stored procedures using the Java language. The primary purpose of the workshop is to demonstrate the steps required to publish a Java method inside the Oracle 8i Lite database environment.

The Relational Algebra is composed of several operators to assist queries and data manipulation on Relational Databases. The Relational Division operator, particularly, allows simple representations of several queries involving the concept of “for all”, however, the SQL does not have an explicit implementation for it. In this paper, we compare the performance of the best implementation known fo...

Ubiquitous information access becomes more and more important nowadays and research is aimed at making it adapted to users. Our work consists in applying machine learning techniques in order to adapt the information access provided by ubiquitous systems to users when the system only knows the user social group, without knowing anything about the user’s interest. The adaptation procedures associ...

In this paper, I describe multiple aspects that are closely related to the release of S-Store system, including dockerized S-Store system, new benchmark MIMIC2BigDAWG, dockerization of the integrated streaming processing system, verification of new S-Store scheduler and collection of stored procedures statistics. Although many other indispensable works are also finished for the final release, t...
