This paper describes a modular representation and compositional analysis of a system’s hardware and software components, called Fault Propagation and Transformation Calculus (FPTC). We show how, given an architectural description of how components are combined into a whole system, together with an FPTC expression of each component’s failure behaviour, the failure properties of the whole system ...

This inter-disciplinary project, seeks to develop new displays for visually representing physiologic variables, to enhance a clinician’s ability to see and rapidly respond to critical events. A digital architectural visualization of an individual’s physiologic data is created in real time. It is both a probing and representational system that brings together science and art through architectura...

UML has established itself as the leading OO analysis and design methodology. Recently, it has also been increasingly used as a foundation for representing numerous (diagrammatic) views that are outside the standardized set of UML views. An example are architecture description languages. The main advantages of representing other types of views in UML are 1) a common data model and 2) a common s...

The writings of Walter Benjamin include appropriations and transformations of modernist architectural history and theory that offer an opportunity to broaden the interpretation of how the relationship between the 'unconscious' and technologically aided 'optics' is figured in his commentaries on cultural modernity. This essay focuses on three moments in his writings, each of which touches on thi...

For realistic simulations, architecture is one of the most important elements to model and render photorealistically. Current techniques of converting architectural plans or survey data to CAD models are labor intensive, and methods for rendering such models are generally not photorealistic. In this work, we present a new approach for modeling and rendering existing architectural scenes from a ...

Root system traits are important in view of current challenges such as sustainable crop production with reduced fertilizer input or in resource-limited environments. We present a novel approach for recovering root architectural parameters based on image-analysis techniques. It is based on a graph representation of the segmented and skeletonized image of the root system, where individual roots a...

Historically, progress in the science of programming has primarily been reflected by the evolution of programming languages. We propose that the next step in this evolution is a more comprehensive kind of programs: Rather than being defined exclusively in an extensional terms, we advocate a distinct programming paradigm where a program is specified through two tightly integrated representations...

Heterogeneous parallel systems incorporate different models of parallelism within a single machine or across machines and are well suited for many diverse applications [1, 2, 3]. These systems offer a wealth of underutilized resources for achieving high performance, but are more difficult to program than homogeneous systems. Compilers can and should assist in handling this complexity. Previous ...

There are increasing demands for the explicit representation and subsequent sharing and usage of architectural decisions in the software architecting process. However, there is little known on how to use these architectural decisions, or what type of stakeholders need to use them. This paper presents a use case model that arose from industrial needs, and is meant to explore how these needs can ...

In the state-of-the-art hardware/software (HW/SW) codesign of embedded systems, there lacks of sufficient support for architectural specifications across HW/SW boundaries. Such an architectural specification ought to capture both hardware and software components and their interactions, and facilitate effective design exploitation of HW/SW trade-offs and scalable HW/SW co-verification. In this p...
