We study convergent scalar d-variate subdivision schemes satisfying sum rules of order k ∈ N, with dilation matrix 2I . Using the results of Möller and Sauer in [18], stated for general expanding dilation matrices, we characterize the structure of the mask symbols of such schemes by showing that they must be linear combinations of shifted box spline generators of a quotient polynomial ideal J ....

Analogical reasoning is considered as one of the main mechanisms underlying creativity. “Thinking out of the box” allows the paradigm shift essential to a creative process. More common is the concept of analogical proportion (“2 is to 4 as 4 is to 8”) which can be described within an algebraic framework. When it comes to concepts (“engine is to the car as heart is to the human”), we need to inv...

Laughter and fillers like “uhm” and “ah” are social cues expressed in human speech. Detection and interpretation of such non-linguistic events can reveal important information about the speakers’ intensions and emotional state. The INTERSPEECH 2013 Social Signals Sub-Challenge sets the task to localize and classify laughter and fillers in the “SSPNet Vocalization Corpus” (SVC) based on acoustic...

Enterprise Information Systems (EIS) can be classified into three generations, starting with the application-centric, moving on to the data-centric and then to contemporary thinking, which can be described as process-centric. The overall theme of CONFENIS 2011 was to re-conceptualize EIS. One way of re-conceptualizing is to start with a blank sheet and “think out of the box”. This topic was add...

In order to efficiently use the future generations of supercomputers, fault tolerance and power consumption are two of the prime challenges anticipated by the High Performance Computing (HPC) community. Checkpoint/Restart (CR) has been and still is the most widely used technique to deal with hard failures. Application-level CR is the most effective CR technique in terms of overhead efficiency b...

The paper presents the methodology and the results of checking consistency of the knowledge base of CADIAG-2, a large-scale medical expert system. Such knowledge base consists of a large collection of rules representing knowledge about various medical entities (symptoms, signs, diseases...) and relationships between them. The major portion of the rules are uncertain, i.e., they specify to what ...

We present a method for optimizing inverted index based search engines with respect to phrase querying performance. Our approach adds carefully selected two-term phrases to an existing index. While competitive previous work is mainly based on the analysis of query logs, our approach comes out of the box and uses just the information already contained in the index. Even so, our method can compet...

The snake in the box problem is an NP-hard problem which has been a challenging problem for both computer scientists and mathematicians. It aims to maximize certain types of paths (snakes) in a graph, an n-dimensional hypercube while satisfying certain constraints described using the concept of spread. This thesis identifies a common pattern among the longest snakes which is very similar to the...

Almost all robots are autistic; very few humans are. Out of the box, robots generally do not behave correctly in social settings (involving humans, or other agents). Most researchers treat this challenge behaviorally, by superficially tacking taskand domainspecific social behavior onto functioning individual robots. These rules are built once, and applied once. In contrast, I posit that we can ...

In addition to these conceptual challenges, the availability of tools can be a challenge, too. Similar to the early phase of UML, AUTOSAR tools are rather new and immature, and experience with those tools is not widespread. Tool features might be lacking and the integration of AUTOSAR tools into a company’s overall tool chain will definitely not be provided out of the box by an off-the-shelf to...
