Calculating the Galois Group of Y′ = = = AY + + + B,Y′ = = = AY Completely Reducible

We consider a special case of the problem of computing the Galois group of a system of linear ordinary differential equations Y′ = MY, M C (x)^{n × n}. We assume that C is a computable, characteristic-zero, algebraically closed constant field with a factorization algorithm. There exists a decision procedure, due to Compoint and Singer, to compute the group in case the system is completely reducible. Berman and Singer (1999, J. Pure Appl. Algebr., 139, 3–23) address the case in which M = [yjsco5390x.gif M 1 * 0 M 2 ], Y′ = M_iY completely reducible for i = 1, 2. Their article shows how to reduce that case to the case of an inhomogeneous system Y′ = AY + B, A C (x)^{n × n}, B C (x)ⁿ, Y′ = AY completely reducible. Their article further presents a decision procedure to reduce this inhomogeneous case to the case of the associated homogeneous system Y′ = AY. The latter reduction involves using a cyclic-vector algorithm to find an equivalent inhomogeneous scalar equation L(y) = b,L C(x)[ D ], b C (x), then computing a certain set of factorizations of L in C(x)[D ]; this set is very large and difficult to compute in general. In this article, we give a new and more efficient algorithm to reduce the case of a system Y′ = AY + B,Y′ = AY completely reducible, to that of the associated homogeneous systemY′ = AY. The new method’s improved efficiency comes from replacing the large set of factorizations required by the Berman–Singer method with a single block-diagonal decomposition of the coefficient matrix satisfying certain properties.

Ubicomp challenges in collaborative scheduling: Pin&;Play at the Göteborg film festival

Ubicomp technology faces many technical challenges, which makes it difficult to test in real world situations. However, understanding and building for everyday practices is crucial for ubicomp designers, in order to push the technological development in the directions needed. We have developed and tested a ubiquitous computing prototype supporting collaborative scheduling. It is based on Pin&Play, a surface-based networking technology with interactive pushpins. The team of a local film festival was engaged in the development process, which resulted in a partial implementation illustrating how their current work practice could be supported. Drawing on this particular design case, we report findings and discuss challenges for ubicomp technology in general.

Towards the interactive filmic narrative—“Transparency”: An experimental approach

Nowadays, the cinematographic language claims for a specific type of interpretation and understanding. The emergence of the digital image and the innovative immersive reception devices provide new and diverse possibilities of reading and interacting within the filmic narrative. That is to say, cinema is constantly reinvented and explores potential renewals within the new interactive medias. This article reflects not only on the mutations of the filmic narrative, but also on its adaptation to interactivity. It proposes, also, new models of implementation, from traditional filmic narrative towards an interactive one. The experimental project Transparency illustrates it—it is a cinematographic project, which has the main goal of studying the interactive filmic narrative. An original plot has been created and adapted to an interactive narrative structure. The project is presented under the form of an installation allowing the spectators to choose the narrative sequences of the story.

Interactive whiteboards: Real beauty or just “lipstick”?

There has been extensive investment by governments and individual schools in interactive whiteboard technology in developed countries premised on the assumption that their use in education will impact positively on learners’ achievements. Developing countries, such as South Africa, keen to raise attainment among their learners are following suit. While at least one of the nine provinces in South Africa had undertaken pilot roll-outs of interactive whiteboards (IWBs) in schools, the Eastern Cape Department of Education commissioned a feasibility study to determine teachers and learners perceptions of the potential benefits and drawbacks of using interactive pen technology, specifically the eBeam, in their teaching and learning environments, before embarking upon a large scale roll-out. This paper reports on a case study of three government schools and highlights the learners and teachers’ enthusiasm about the “big screen” and the multimedia options, but also raises concerns about the lack of ICT literacy displayed by teachers and learners and the cost of technology. As most of the benefits mentioned by the teachers and learners seemed to accrue to the use of the laptop and data projector combination and most of the drawbacks emanated from the use of the interactive pen technology itself, we suggest that it may not be expeditious to attempt to “leap-frog” the use of interactive technologies. Instead we suggest that an evolution of ICT related pedagogy is necessary to make optimal use of interactive pen technologies such as the eBeam and that teachers should be offered technologies, not have them imposed upon them.     

Haptic‐constraint modeling based on interactive metaballs

Adding interactive haptic‐constraint sensations is important in interactive computer gaming and 3D shape design. Usually constraints are set on vertices of the object to drive the deformation. How to simulate dynamic force constraints in interactive design is still a challenging task. In this paper, we propose a novel haptic‐constraint modeling method based on interactive metaballs, during which the haptic‐constraint tools are attracted to the target location and then control the touch‐enabled deformation within the constrained areas. The interactive force feedbacks facilitate designers to accurately deform the target regions and fine carve the details as their intention on the objects. Our work studies how to apply touch sensation in such constrained deformations using interactive metaballs, thus users can truly feel and control the soft‐touch objects during the deforming interactions. Experimental results show that the dynamic sense of touch during the haptic manipulation is intuitively simulated to users, via the interacting interface we have developed.

1 × 4 optical switch based on electrowetting

In this paper, we report a 1 × 4 optical switch using deformable liquid droplet. The deformation is produced by the electrowetting on dielectric phenomenon. The device consists of a dyed oil and a transparent conductive liquid sealed in a transparent cylinder. The top glass cover of the device has four independently addressable electrodes for the actuation of the liquid dome in each direction. In the voltage‐off state, incident light is absorbed by the dyed liquid. When the voltage is applied to the liquid, the dome of the transparent liquid is uplifted and then spreads to four different directions because of the effect of electrostatic force. Accordingly, the transparent liquid pushes the dyed oil out to form a light path. The device with simple structure can freely control multiple switch apertures through changing the driven voltage. In addition, we analyze the electro‐optical characteristics such as transmittance, response time (open time ~110 ms, close time ~160 ms), contrast ratio (~661:1).     

Biorthogonal Wavelets Based on Interpolatory Subdivision

This article presents an efficient construction of biorthogonal wavelets built upon an interpolatory         subdivision for quadrilateral meshes. The interpolatory subdivision scheme is first turned into a scheme for reversible primitive wavelet synthesis. Some desired properties are then incorporated in the primitive wavelet using the lifting scheme. The analysis and synthesis algorithms of the resulting new wavelet are finally obtained as local and in-place lifting operations. The wavelet inherits the advantage of         refinement with added levels of resolution. Numerical experiments show that the lifted wavelet built upon interpolatory         subdivision has sufficient stability and better performance in dealing with closed or open semi-regular quadrilateral meshes compared with other existing wavelets for quadrilateral manifold meshes.

Pre‐computed Gathering of Multi‐Bounce Glossy Reflections

Recent work in interactive global illumination addresses diffuse and moderately glossy indirect lighting effects, but high‐frequency effects such as multi‐bounce reflections on highly glossy surfaces are often ignored. Accurately simulating such effects is important to convey the realistic appearance of materials such as chrome and shiny metal. In this paper, we present an efficient method for visualizing multi‐bounce glossy reflections at interactive rates under environment lighting. Our main contribution is a pre‐computation–based method which efficiently gathers subsequent highly glossy reflection passes modelled with a non‐linear transfer function representation based on the von Mises–Fisher distribution. We show that our gathering method is superior to scattered sampling. To exploit the sparsity of the pre‐computed data, we apply perfect spatial hashing. As a result, we are able to visualize multi‐bounce glossy reflections at interactive rates at a low pre‐computation cost.     

The use of interactive media among today’s youth: Results of a survey

The intensive use of interactive media has led to assertions about the effect of these media on youth. This paper presents a quantitative study on the position of interactive media in young people’s lives. Rather than following the assumption of a homogeneous generation, we investigate the existence of a diversity of user patterns. The research question for this paper: Can patterns be found in the use of interactive media among youth? We answer this question by a survey among Dutch youngsters aged 10–23. Four clusters of interactive media users, namely Traditionalists, Gamers, Networkers and Producers were identified using cluster analysis. Behind these straightforward clusters, a complex whole of user activities can be found. Each cluster shows specific use of and opinions about interactive media. This provides a contextualized understanding of the position of interactive media in the lives of contemporary youth, and a nuanced conceptualization of the ‘Net generation’. This allows for studying the intricate relationship between youth culture, interactive media and learning.
