One of the most important parameters to consider when designing a manipulator is the number of degrees-of-freedom (DOFs). This article focuses on the question: How many DOFs are necessary and sufficient for fault tolerance and how should these DOFs be distributed along the length of the manipulator? A manipulator is fault tolerant if it can complete its task even when one of its joints fails an...

The objective of this paper is to improve the use of the hardware resources of the trace cache mechanism, reducing the implementation cost with no performance degradation. We achieve that by eliminating the replication of traces between the instruction cache and the trace cache. As we show, the trace cache mechanism is generating a high degree of redundancy between the traces stored in the trac...

1 Foreword This text is divided in two parts. The first one, the prerequisites, introduces all the necessary concepts of coding theory. If the reader is familiar with the basics of information and coding theory, he might skip this part and go directly to the second part, which is the core of this thesis. This second part studies an algorithm which improves the decoding of Reed-Solomon codes. Fo...

Human-to-humanoid motion retargeting is an important tool to generate human-like humanoid motions. This retargeting problem is often formulated as a Cartesian control problem for the humanoid from a set of task points in the captured human data. Classically, Cartesian control has been developed for redundant systems. While redundancy fundamentally adds new subtask capabilities, the degree to wh...

The quantum based systems could be the next steps in improving the satellite communication. The actual implementation of quantum cryptography systems would be invaluable, allowing for the first time the practical possibility of one-time-pad-encrypted, undecipherable communication, which will offer an essentially new degree of security in future satellite communications. They offer secure key di...

Context: In large software organizations with a product line development approach, system test planning and scope selection is a complex task. Due to repeated testing: across different testing levels, over time (test for regression) as well as of different variants, the risk of redundant testing is large as well as the risk of overlooking important tests, hidden by the huge amount of possible t...

The literature on numerical perception is reviewed from the standpoint of research on selective attention, and predictions are made concerning the dimensional interaction between physical and numerical size of numerals. We manipulated stimulus differences to make the classification of numerical value slightly better (Experiment 1), substantially better (Experiment 2), or worse (Experiments 3-4)...

AbstmctDifferent multiple redundancy schemes for fault detection and correction in computational arrays are proposed and analyzed. The basic idea is to embed a logical array of nodes onto a processor/switch array such that d processors, 1 2 d 5 4, are dedicated to the computation associated with each node. The input to a node is directed to the d processors constituting that node, and the outpu...

BACKGROUND The redundancy hypothesis predicts that the species redundancy in a plant community enhances community stability. However, numerous studies in recent years questioned the positive correlation between redundancy and stability. METHODOLOGY We explored the relationship between the species redundancy, functional redundancy and community stability in typical steppe grassland in Northern...
