There are two very different approaches to understand functioning of the brain. First, there is a huge progress in the research of the neurological and neurophysiological properties of different brain substructures, circuits, networks, single cells, synapses and their molecular properties. It contributes to the progress of research in the fields of basic medical sciences and the dramatic increase in average life expectancy. On the another side that does not directly follows neurological developments, it is our introspection related to individual ways of thinking in order to solve different problems that also involve human creativity (cognitive theory of mind). We use many diverse ways of thinking, and they depend on different circumstances. Especially interesting are influences of intuition, feelings and emotions on our creativity, which is in a large part are also related to the social interactions (affective empathy). In this work, we formalise emotional scales and transfer of emotions between individuals (social emotional thinking). We also demonstrate a continuity of the emotion transfer mappings, and an importance of the interactions between emotional faces. It is not only human specific to show and to react to face emotions, but strong and wide human social interactions are based on the precise emotional social thinking. By measuring critical values of face deformations that may influence mutual emotions, we can test precision and tolerance of human visual and emotional systems. By introduction indiscernibility relations between individual reading of face parts deformation, we have used rough set theory to probe social emotional thinking. As one of us have demonstrated that the visual system has properties that follows rough set theory (cognitive theory of mind), this work extends this concept to the social emotional interactions (cognitive and affective theory of mind). As in modern world IT-information technology-has became driving factor in the process of globalisation by creating effective channels of information exchange; hence it becomes extremely important to analyse emotional meaning (cognitive empathy) for this vast information flow. By using as described here, rough set theory to determine, which parts of information have significant emotional influence, our model may give grounds to increase the collective well-being. © IOS Press and the authors.

Summary: Modern sequencing platforms produce huge amounts of data. Archiving them raises major problems but is crucial for reproducibility of results, one of the most fundamental principles of science. The widely used gzip compressor, used for reduction of storage and transfer costs, is not a perfect solution, so a few specialized FASTQ compressors were proposed recently. Unfortunately, they are often impractical because of slow processing, lack of support for some variants of FASTQ files or instability. We propose DSRC 2 that offers compression ratios comparable with the best existing solutions, while being a few times faster and more flexible. Availability and Implementation: DSRC 2 is freely available at http://sun.aei.polsl.pl/dsrc. The package contains command-line compressor, C and Python libraries for easy integration with existing software and technical documentation with examples of usage.© The Author 2014.

Defuzzification functionals, which play the main role when dealing with fuzzy controllers and fuzzy inference systems, for convex as well for ordered fuzzy numbers, are discussed. Three characteristic conditions for them are formulated. It is shown that most of the known defuzzification functionals satisfy them. Motivations for introducing the extended class of convex fuzzy numbers are presented, together with operations on them.© 2013 IEEE.

Moving Integrated Product Development to Service Clouds in the Global Economy - Proceedings of the 21st ISPE Inc. International Conference on Concurrent Engineering, CE 2014 | Year: 2014

Improvements in the design and manufacturing processes, and the related technologies that enable them, have led to significant improvements in product functionality and quality. However, the need for further improvements in these areas is needed due to increasing complexity of integrated product process development (IPD). Introduction of a new IPD project is more complex than most people realize and getting more complex all the time. Some of the complexity is due to rapidly changing and advancing technologies in underlying hardware and software, and the interplay of individual complex methods in system configurations. A strong IPD methodology, with intrinsically higher fidelity models to actualize the agile service-oriented design/manufacturing processes, is needed which can be continuously upgraded and modified. This paper describes a true service-oriented architecture that describes everything, anywhere, anytime as a service with the innovative service-oriented process expression (front-end services called exertions) and its dynamic and on-demand actualization (back-end service providers). Domain-specific languages (DSLs) for modeling or programming or both (mogramming) are introduced and their unifying role of front/back-end services is presented. Moving to the back-end of IPD systems front-end process expressions, that are easily created and updated by the end users, is the key strategy in reducing complexity of large-scale IPD systems. It allows for process expressions in DSLs to become directly available as back-end service providers that normally are developed by experts and software developers that cope constantly with the compatibility, software, and system integration issues that become more complex all the time. © 2014 The Authors and IOS Press.

This work extends the authors' contribution to the International Conference on Rough Sets and Current Trends in Computing (RSCTC 2008) held at the University of Akron in October 2008. It is dedicated to the topic of granular computing, formalized within the theory of rough mereology, as proposed by Polkowski; as an application of the idea of a granular reflection of data and of classifiers induced from it (Polkowski, 2005), we give an account of recent results in this area. A scheme for classifier construction based on factoring a classifier through a granular reflection of data; voting by granules of training objects; voting by granules of decision rules induced from the training set; voting by granules induced from a granular reflection of data, is presented here. In voting cases, voting is based on weights computed by means of rough inclusions induced from residual implications of continuous t-norms. The results show a high effectiveness of this approach as witnessed by the reported tests with some well - known data sets from University of California, at Irvine (UCI) repository whose results are compared against the standard rough set exhaustive classifier whose accuracy is indicated under the radius of "nil."

Most enterprise computing programs are still not written in metaprogramming languages but rather composed line by line in software programming languages as they were decades ago. These programming languages are poorly suited to expressing enterprise processes targeted at complex, domain-specific and transdisciplinary problems. The current state of the art is that legacy programs and scripts can be used as programming instructions provided by dynamic service objects. New metaprograms (programs of programs) require relevant operating systems managing service objects as a virtual service metaprocessor. However, there are presently no acceptable metaprogramming methodologies to program, deploy, and dynamically federate these relevant service objects into a virtual processor securely and efficiently with fault detection and recovery. In this paper the emerging metacomputing SORCER platform with its federated method invocation and exertion-oriented programming model is contrasted with service protocol-oriented architectures (e.g., OGSA, CORBA, RMI) which limit us to one fixed wire protocol, static network configurations, and often restricts us to heavyweight containers (e.g., application servers) for hosting service objects. © 2010 Springer-Verlag Berlin Heidelberg.

Most work on activity recognition focuses on 2D image properties, holistic spatiotemporal representations, or space-time shapes in image domain rather than with 3D pose in a body-centric or world frame. Such techniques rely on advanced pattern recognition algorithms and interpreting complex behavioral patterns. In this work we posit that it is possible to achieve 3D pose tracking using videos recorded in multi-camera surveillance systems. We show experimental results that were obtained on PETS 2009 datasets. The estimation of the 3D articulated motion is achieved using a modified particle swarm optimization. © 2011 IEEE.

The combination of longer life expectancy, evolving socio-economical norms and conditions, and new technologies are dramatically changing life after retirement, and not always for the better. In more and more countries, pensioners find themselves with many years in front of them, some of them likely characterized by reduced physical and cognitive abilities. For older adults, this span of time out of the workforce was traditionally devoted to the role (and source of great joy) of caring for grandchildren. However, this role is fading out because of increased mobility of children, which often live far away for work, love, or other reasons, leading to an increase of loneliness and social isolation. This project aims at rethinking long life and understanding the socio-economical context that can make this period of life more exiting and attractive. The specific angle we take is that of enabling older adults of all ages - and specifically including adults who cannot leave their home or that have reduced cognitive abilities - to learn, grow, interact, and contribute to society through ICT. In other words, we aim at enabling adults to be contributors to societal wellbeing. We generically refer to this group of abilities as life participation abilities, and we focus on these aspects because studies tell us that the ability of interacting and feeling useful and helpful to others is essential to a persons wellbeing, sometimes more so than health. The multi- and inter-disciplinary nature of the project provides the perfect environment for collaboration and knowledge transfer. As such, it requires the expertise and perspective that only the consortium as a whole can provide. The synergies that we build in the project will help not only in the materialization of the solutions starting from the original problems, challenges and requirements, but they will also foster the growth of research and innovation skills of the researchers and institutions involved in the project.

In this paper, enhanced four-node shell elements with six DOFs/node based on the Hu-Washizu (HW) functional are developed for Green strain. The drilling rotation is included through the drilling rotation constraint equation. The key features of the approach are as follows. The shell HW functional is derived from the shell potential energy functional, which is an alternative to the derivation from the three-dimensional HW functional. This method is more versatile as it enables the derivation of the so-called partial HW functionals, with different treatment of the bending/twisting part and the transverse shear part of strain energy. For the membrane part of HW shell elements, a seven-parameter stress, a nine-parameter strain and a two-parameter enhanced assumed displacement gradient enhancement are selected as optimal. The assumed representations of stress and strain are defined in skew coordinates in the natural basis at the element's center. This improves accuracy and has positive theoretical consequences. The drilling rotation constraint equation is treated by the perturbed Lagrange method. The faulty term resulting from the equal-order approximations of displacements and the drilling rotation is eliminated, and one spurious mode is stabilized using the gamma method. The proposed formulation is insensitive to the element's distortions and yields a large radius of convergence in the examples involving in-plane bending. The performance of 4 four-node shell HW elements, having different bending/twisting and transverse shear parts, is analyzed on several numerical examples. Such aspects are considered as: accuracy, radius of convergence, required number of iterations of the Newton method or the arc-length method and time of computations. The element with 29 parameters (HW29) is selected as the best performer. © 2011 John Wiley & Sons, Ltd.
