After noting that informal documents and formal knowledge bases are far from ideal for discussing or retrieving technical knowledge, we propose mechanisms to support the sharing, re-use and cooperative update of semi-formal semantic networks, assign values to contributions and credits to the contributors. We then propose ontological elements to guide and normalize the construction of such knowl...

W investigate the epistemology of trust in social networks. We posit trust as a special epistemic state that depends on actors’ beliefs about each others’ beliefs as well as about states of the world. It offers new ideas and tools for representing the core elements of trust both within dyads and larger groups and presents an approach that makes trust measurable in a noncircular and predictive, ...

This technical report describes the project of manual annotation of extended textual coreference and bridging relations, which runs at the Institute of Formal and Applied Linguistics, Faculty of Mathematics and Physics, Charles University in Prague, since 2009. It contains the typology of coreference and bridging relations, classification of elements that are annotated for coreference and the a...

This paper considers the design of feedback controllers for linear, time-invariant, spatially distributed systems in an approach which generalises the H∞-framework and in particular the H∞ loop-shaping method. To this end, we introduce a class of spatially distributed system models called /nite dimensional, distributed, linear, time-invariant systems. Sensors and actuators are considered to be ...

A method for preserving the LTI system topology during the application of an sto z-plane transform is described. The produced discrete-time systems keep the important characteristics of the original continuous-time systems in cases of modulated parameters. A further extension to the case of contained nonlinearities is made.

People with cancer experience many unanticipated symptoms and struggle to communicate them to clinicians. Although researchers have developed patient-reported outcome (PRO) tools to address this problem, such tools capture retrospective data intended for clinicians to review. In contrast, real-time tracking tools with visible results for patients could improve health outcomes and communication ...

Student-teacher training allows a large teacher model or ensemble of teachers to be compressed into a single student model, for the purpose of efficient decoding. However, current approaches in automatic speech recognition assume that the state clusters, often defined by Phonetic Decision Trees (PDT), are the same across all models. This limits the diversity that can be captured within the ense...

The paper deals with a steganalysis of PQ algorithm by means of neural networks. The paper continues with the research of steganalysis by means of neural networks and brings results for the other steganography tool and also simulation results for different settings of neural network.

In a 29-year study of 6,203 individuals ranging in age from 41 to 96 years at initial assessment, we evaluated the relative and combined influence of 65 mortality risk factors, which included sociodemographic variables, lifestyle attributes, medical indices, and multiple cognitive abilities. Reductions in mortality risk were most associated with higher self-rated health, female gender, fewer ye...

In Thailand physical violence among male adolescents is considered a significant public health issue, although there has been little published research into the aetiology and functions of violence in Thai youth. Research in this area has been hampered by a lack of psychometrically sound tools that have been validated to assess problem behaviours in Asian youth. The purpose of this paper is to p...
