This paper describes how the RM-ODP approach for system specification is applied to the description of the IT architectures of a large Swiss bank. The IT organization of UBS AG is defining several architectures based upon a business model which describes the main objectives of the bank considering the IT requirements. The semantics and the components of each architecture are explained using the...

Both software engineering research community and standardisation organisations recognized a need for a general standard as a guideline for modelling software architectures. Even though the ANSI/IEEE Standard 1471 provides a widely applicable reference model for that purpose, it merely identifies a need of a rationale for the architectural concepts selected, but does not include any further prin...

This paper deals with hierarchical, multiple fieldbus-based architectures using four case studies that present some concepts reusable in developing the interconnections of intelligent sensors and actuators. The single-master, lowlevel fieldbusses considered involve (1) ASI (ActuatorSensor-Interface), which is an example of a lowest-level industrial interconnection; (2) NBIP (Nine-Bit Interproce...

It highlights the article by C. Ryu, P. W. Blackburn, A. A. Blinova, and M. G. Boshier, published in Physical Review Letters 111, 205301 (2013). It also implies that macroscopic quantum effects in ...

That dropping the rational expectations assumption opens the door to many more patterns of volatility as equilibrium phenomena is not surprising. That this continues to be so even after requiring the expectations to be formed rationally is indeed surprising. In effect, requiring the agents to form expectations rationally —in the sense of being such that they maximize at any time the likelihood ...

Realistic pictures, whether paintings, photographs or rendered images of models, are traditionally obtained using classical perspective projection. Here I focus on pictures of people and discuss evidence suggesting that, for best results, full-length realistic-looking portraits should be produced by combining multiple viewpoints. I test this prediction experimentally and find that full-length p...

Conditioning the data generating process of a time series on the season periodic time series models have become a promising tool for the analysis of processes exhibiting patterns of seasonal variation. From an econometric viewpoint such models have the appealing property that they are able to embed assumptions like seasonally varying utility functions, seasonal technologies etc. Since seasonal ...

If architecture representation is the problem (P), and the UML is the solution (S), how do we get from P to S? In this paper, I introduce the idea of viewpoint modeling as a part of the answer. A viewpoint, as defined in IEEE 1471, defines a set of architectural concerns and the resources needed to address those concerns. A viewpoint gives an architect the resources with which to construct an a...

This note compares some current theoretical mathematical work on spatial networks with data on inter-city road networks within States. In designing a network, a natural constraint is the total length, and a natural objective is to want the route length `(i, j) between typical cities i, j to be not much longer than straight line distance d(i, j). Write r(i, j) = `(i,j) d(i,j) − 1 for the relativ...
