In order to utilize the contemporary advanced technology, business processes need sound software support. With respect to this, one frequent cause of software project failure is the mismatch between the business requirements and the actual functionality of the delivered software application. To solve this problem, it is necessary to build software stemming out from a business process model. Aim...

In this paper we sketch how the use of building blocks provides added value for improving the effectiveness of simulation studies. Research conducted by other groups regarding building blocks is in our view not yet sufficient for successful application in the field of discrete event simulation. In addition the sets of building blocks provided by simulation vendors do not provide the added value...

Oversampled analog-to-digital ( A D ) converter architectures offer a means of exchanging resolution in time for that in amplitude so as to avoid the difficulty of implementing complex precision analog circuits. These architectures thus represent an attractive approach to implementing precision A/D converters in scaled digital VLSI technologies. This paper examines the practical design criteria...

This paper reports on an ongoing research project on an "nonpencil" approach in generating architectural forms using nontraditional geometries. Space curves are investigated to determine nodal points in 3D space, which are then interpreted into common architectural elements. The nodal points are used in a variety of ways to generate walls, columns, floors, and volumes. The determination of form...

Conventional switch-mode dc-dc converters are operated at frequencies in the order of hundreds of kHz to single MHz. Switching frequencies in the order of tens of MHz would enable applications of RF converters in low power communications and computing integrated circuits with dynamic voltage scaling. Controllers for these converters would have to operate with a bandwidth in the GHz range. The m...

The large number of channels (15.7 millions), needed for the silicon pixel detector under development for the ALICE ITS, requires a careful study of the statistical fluctuations of the front-end electronics performance. By means of classical techniques, such as the Principal Component Analysis, and of new ones used to perform a “realistic” worst case analysis, various configurations of basic CM...

Parabolic subgroups are the building blocks of Artin groups. This paper extends previous results Cumplido, Gebhardt, Gonzales-Meneses and Wiest, known only for parabolic finite type groups, to FC-type We show that class is closed under intersection. also study an analog curve complex mapping group constructed by Cumplido et al. using subgroups. extend construction this complex, called subgroups...

HBIST (Hybrid-Built-In-Selftest) is a very efficient method for testing analog parts within mixed-signal circuits by using a provided BIST (BuildIn-Selftest)-environment in the digital part of a circuit. For using HBIST of nonlinear analog circuits a new kind of signature called add-signature is proposed. The advantages and disadvantages of the add-signature are demonstrated together with simul...

This paper focuses on the analog VLSl design of a reduced KII set and network, which are basic building blocks in the computational model of the olfactory cortex proposed by Walter Freeman [ I ] . Previous implementation issues were discussed in [3][4] but this paper will present recent developments in the circuit design of individual blocks in a reduced KII set as well as a system architecture...
