Information visualization is strongly related to human perception, human behavior, and in particular human interaction. It is a discipline that focuses on human to enable him gathering insights, knowledge, and solving various and heterogeneous tasks. The human-centered characteristic of information visualization requires valid and proper user studies that improve the system or validate their benefits. New methods, techniques, or approaches of information visualization are commonly evaluated. However, the evaluation is either time and cost consuming or they are made minimum resources that leads to results, which may not be valid. In particular the number of participants is commonly restricted and does not enable a valid assumption about the results. Thus performance measures plays a key role in information visualization, existing web-survey tools are not convenient. We introduce in this paper a new method that enables web-based evaluations of information visualization systems. Our main contribution is the enhancement of web-based survey tools with performance measures. Our approach enables the measurement of task-completion time, correctness of solved tasks, and includes a number of pre- and post-questionnaires. © 2015 The Authors

The paper presents the motion simulation of a Wing in Ground craft with a Lippisch configuration which is stable in terms of static stability. The influence of wind and wave perturbations on the dynamic stability of the flight are investigated. The analysis of safety and stability used two different approaches. Based on frequency domain simulation, the first approach derived from the classical stability theory utilizes the aerodynamic coefficients and their linearized derivatives. The second approach based on time domain simulation uses the coefficients with full respect to the nonlinear character of aerodynamics in ground effect. The trajectory is used to evaluate the dynamic stability and flight safety of the craft. From the results for typical perturbations, the limitations of the classical stability theory for the flight safety of Wing in Ground craft are shown. The results show the necessity of the automatic control system even for a satisfying stable craft predicted by the linear theory. The demand of high performance together with the hard constraints for states and control inputs are challenging for the controller design. A proportional-integral-derivative controller is studied to secure the flight safety of small craft under different perturbation and a methodology for designing a control system for operation under various weather conditions is illustrated.

Coloured hybrid Petri nets for systems biology 5

Coloured hybrid Petri nets for systems biology

5th International Workshop on Biological Processes and Petri Nets, BioPPN 2014

Coloured Petri nets are imperative for studying bigger biological models, particularly, those which expose repetition of components. Such models can be easily scaled by minor changes of a few parameters. Similarly, studying certain biological phenomena necessitates the existence of discrete and continuous variables as well as continuous and stochastic processes in one and the same model. Thus, hybrid modelling and simulation is indispensable to deal with these challenges. In this paper we introduce a generic Petri net class, Coloured Generalised Hybrid Petri Nets (GHPNC) by combining coloured Petri nets and Generalised Hybrid Petri Nets (GHPN), which integrates discrete and continuous places as well as stochastic and deterministic transitions on the coloured level. Moreover, we present a case study which illustrates a possible and typical application where such a Petri net class is highly required.

In medical imaging, image enhancement is an important step before further processing is being carried out. It aims to improve the quality of the images as uncertainties maybe inherited due to several factors. In this paper, the image of Flat EEG (fEEG) is enhanced (in terms of contrast enhancement) by using intuitionistic fuzzy set (IFS) approach. The enhanced images are compared through two different membership functions whereby it is implemented in the initial step of the enhancement process. It is observed that cluster centres with darker background appeared in the resultant images as compared to the input image. Moreover, the contrast comparison between the input and output images are being carried out.

Technical developments in neurobiology have reached a point where the acquisition of high resolution images representing individual neurons and synapses becomes possible. For this, the brain tissue samples are sliced using a diamond knife and imaged with electron-microscopy (EM). However, the technique achieves a low resolution in the cutting direction, due to limitations of the mechanical process, making a direct visualization of a dataset difficult. We aim to increase the depth resolution of the volume by adding new image slices interpolated from the existing ones, without requiring modifications to the EM image-capturing method. As classical interpolation methods do not provide satisfactory results on this type of data, the current paper proposes a re-framing of the problem in terms of motion volumes, considering the depth axis as a temporal axis. An optical flow method is adapted to estimate the motion vectors of pixels in the EM images, and this information is used to compute and insert multiple new images at certain depths in the volume. We evaluate the visualization results in comparison with interpolation methods currently used on EM data, transforming the highly anisotropic original dataset into a dataset with a larger depth resolution. The interpolation based on optical flow better reveals neurite structures with realistic undistorted shapes, and helps to easier map neuronal connections. © 2011 ACM.

ChronoLeap: The Great World's Fair Adventure utilizes the educational potential of immersive 3D virtual venues for children and early adolescents between 9 and 13. Virtual reality environments transport the mind beyond the 2D bounds of text or photographs;they engage the imagination and can be a powerful tool for conveying educational content [1]. ChronoLeap leverages these innate qualities and weaves together the individual threads of single disciplines into a multi-disciplinary tapestry of web-based exploration through the 1964/65 New York World's Fair. Through their myriad of pavilions and exhibits, World Fairs offer links to science, technology, engineering, mathematics, art and humanities topics. ChronoLeap provides an immersive 3D environment with highly accurate and detailed models, and merges it with games and themes designed to provide users an educational STEAM environment. The project is a collaborative effort between the University of Central Florida, Queens Museum of Art and New York Hall of science. © 2013 Springer-Verlag Berlin Heidelberg.
