In signal processing applications it is often necessary to extract oscillatory components and their properties from time frequency representations e.g . the windowed Fourier transform or wavelet transform . The first step in this procedure is to find an appropriate ridge curve a sequence of amplitude peak positions corresponding to the component of interest and providing a measure of its instantaneous frequency . This is not a trivial issue and the optimal method for extraction is still not settled or agreed . We discuss and develop procedures that can be used for this task and compare their performance on both simulated and real data . In particular we propose a method which in contrast to many other approaches is highly adaptive so that it does not need any parameter adjustment for the signal to be analyzed . Being based on dynamic path optimization and fixed point iteration the method is very fast and its superior accuracy is also demonstrated . In addition we investigate the advantages and drawbacks that synchrosqueezing offers in relation to curve extraction . The codes used in this work are freely available for download . 


Summary: Identifying and following instantaneous ridge frequencies in complex signals. Adaptive universal extraction of ridge frequencies from time frequency representations. Comparison of the performance of different approaches for ridge curve extraction. Relative performance of the synchrosqueezed transforms in terms of curve extraction. Freely available codes implementing the new method.
Portable gas analyzers have become a powerful tool for the real time monitoring of volcanic gas composition over the last decade . Gas analyzers make it possible to retrieve in real time the chemical composition of a fumarole system or a plume in an open conduit volcano via periodic field deployments or at permanent stations . The core of a multicomponent volcanic gas analyzer consists of spectroscopic and electrochemical sensors that are used to determine the concentrations of the most abundant volcanic gases in a diluted plume and their mutual molar ratios . Processing such data is often difficult due to the high sensitivity of the sensors to environmental conditions such as humidity gas concentrations and pressure with all involving occasional instrumental drift . Analyses require accurate and time consuming processing by an operator . This paper presents a stand alone program for the processing of chemical data obtained using the MultiGAS called Ratiocalc . The Ratiocalc program has a user friendly interface to enable volcanologists to process large datasets in a simple and rapid manner thereby reducing the processing time associated with volcano monitoring and surveying . 


Summary: Portable gas analyzers for the real time monitoring of volcanic gas composition. Ratiocalc software for the processing of chemical data obtained using the MultiGAS. Electrochemical and infrared sensors for volcanic gas measurements. Calibration cross interference correction georeferencing of MultiGAS data.
Interactive displays are becoming an increasingly popular civic engagement mechanism for collecting user feedback in urban settings . However to date no study has investigated how the situatedness of public displays affects the quantity and quality of collected feedback and how public displays compare to traditional paper or web feedback mechanisms . We answer these research questions in a series of lab and field studies . We demonstrate that because people tend to approach this technology with no specific purpose in mind the feedback collected with public displays is noisier than web and paper forms . However we also show that public displays attract much more feedback than web and paper forms and generate much more interest . Furthermore we found that users appropriated our technology beyond its original purpose . Our analysis provides implications on the tradeoffs of using public displays as a feedback mechanism and we discuss ways of improving the collected feedback using public displays . 


Summary: Public displays paper and web forms were compared as feedback mechanisms. We examined the quantity and quality of feedback obtained from each medium. Public displays produced a high quantity of feedback but mostly noise. Paper and web forms generated lower quantity of feedback but better quality. Public displays can be leveraged as significant interest generators.

HEVC is the latest coding standard to improve the coding efficiency by a factor of two over the previous H.264 AVC standard at the cost of the increased complexity of computation rate distortion optimization is one of the computationally demanding operations in HEVC and makes it difficult to process the HEVC compression in real time with a reasonable computing power . This paper aims to present various simplified RDO algorithms with the evaluation of their RD performance and computational complexity . The algorithms for the simplified estimation of the sum of squared error and context adaptive binary arithmetic coding proposed for H.264 AVC are reviewed and then they are applied to the simplification of HEVC RDO .

Anaglyph video is a recent trend in movies and multimedia the method has also been recently developed for conversion of such videos from traditional 2D screens or by rendering stereoscopic media into 3D video . There have also been many studies regarding movie playing and other types of entertainment that uses olfactory displays or smell generators . These devices are capable of generating a considerable number of different odors with different intensities yet still have some limitations and are not ready for commercial use . In this study a complete solution is presented for a user to experience olfactory sensations with a displayed video on a PC with auditory and 3D visual effects using a novel olfactory display device based on a micro porous piezoelectric film that is capable of digitally producing fine particles of scent material with precision quantity and speed .

The aim of this study is to develop an effective method to analyze regions of interest . Two experiments were conducted at different times using different groups of observers with different images on different displays . Observers eye movement data were collected . Fixation maps showing CIELAB L values were created . The L values between the two maps were used to quantify differences in visual fields counting methods observer variability and repeatability between the two experiments . The results showed that fixation maps can be used to effectively analyze the distribution of eye movements between images . The L value calculated for two fixation maps is easy to understand and computes differences based only on ROIs more effectively than differences based on the entire image . The results from the two experiments were consistent indicating that eye tracking data are robust for evaluating image quality . 


Summary: We develop an effective method to analyze human s regions of interest ROI . Results of two experiments can be compared to test the robustness of the method. The CIEL has been analyze to check the amount of variation between fixation maps. The fixation map can be easy used to analyze the ROIs between images. The delta L value is more effective by computing the fixation map of entire image.
A construction of spline spaces suitable for representing smooth parametric surfaces of arbitrary topological genus and arbitrary order of continuity is proposed . The obtained splines are a direct generalization of bivariate polynomial splines on planar partitions . They are defined as composite functions consisting of rational functions and are parametrized by a single parameter domain which is a piecewise planar surface such as a triangulation of a cloud of 3D points . The idea of the construction is to utilize linear rational transformations to endow the piecewise planar surface with a particular differentiable structure appropriate for defining rational splines . 


Summary: A new approach for constructing smooth parametric surfaces is proposed. Bivariate polynomial splines are generalized to rational splines. The genus and order of continuity of the surfaces can be arbitrary. The construction employs linear rational transformations as transition maps. The computational properties of the new splines are similar to those of the classical splines.
Graph sampling refers to the process of deriving a small subset of nodes from a possibly huge graph in order to estimate properties of the whole graph from examining the sample . Whereas topological properties can already be obtained accurately by sampling current approaches do not take possibly hidden dependencies between node topology and attributes into account . Especially in the context of online social networks node attributes are of importance as they correspond to properties of the social network s users . Therefore existing sampling algorithms can be extended to attribute sampling but still lack the capturing of structural properties . Analyzing topology and attribute properties jointly can provide valuable insights into the social network and allows for a better understanding of social processes . As major contribution this work proposes a novel sampling algorithm which provides unbiased and reliable estimates of joint topological and attribute based graph properties in a resource efficient fashion . Furthermore the obtained samples allow for the generation of synthetic graphs which show high similarity to the original graph with respect to topology and attributes . The proposed sampling and generation algorithms are evaluated on real world social network graphs for which they demonstrate to be effective . 


Summary: Existing sampling algorithms are extended to node attributes. A novel sampling algorithm is proposed which allows for joint capturing of structure and attribute characteristics. Topological graph similarity measures are extended to additionally assess attribute related similarity. A graph generation method is presented that reproduces topology and attribute related properties of the original graph based on sampling.
Ganchev has recently proposed a new approach to minimal surfaces . Introducing canonical principal parameters for these surfaces he has proved that the normal curvature determines the surface up to its position in the space . Here we prove a theorem that permits to obtain equations of a minimal surface in canonical principal parameters and we make some applications on parametric polynomial minimal surfaces . Thus we show that Ganchev s approach implies an effective method to prove the coincidence of two minimal surfaces given in isothermal coordinates by different parametric equations . 


Summary: A differential equation for the transition to canonical parameters is obtained. The class of holomorphic functions generating one minimal surface is determined. Surfaces homothetic to the general Enneper surface are given. The coincidence of some families of polynomial minimal surfaces is proved.

Publish subscribe is an increasingly popular messaging pattern for distributed systems supporting scalable and extensible programming and optimal spatial temporal and control flow decoupling of distributed components . Publish subscribe middleware and methods were extended towards supporting security in particular confidentiality and increased availability yet a few prior works addressed anonymity of participants . Anonymity of senders and receivers may however be crucial e.g . for supporting freedom of expression in regimes where political repression and censorship prevail . In this article we review basic security and privacy requirements and introduce a new attacker model based on statistical disclosure used to challenge anonymity . We elaborate on design options for privacy preserving publish subscribe systems and present a novel system that leverages peer to peer networking concepts this novel approach protects subscriber anonymity by means of Probabilistic Forwarding and through a novel so called Shell Game algorithm . We verify our solution against the requirements and provide a simulation based analysis of the effectiveness of our approaches in light of our attacker model . The results show that the SG algorithm efficiently protects subscriber anonymity and that anonymity sets can be adjusted via PF . 


Summary: We propose a protocol to construct privacy preserving publish subscribe overlays. Two extensions probabilistic forwarding and the shell game protect anonymity. The construction protects against malicious insiders and global observers. Simulation results show effective privacy protection.
Poly poly is the most successful conducting polymer in terms of the practical application . It can be dispersed in water and some polar organic solvents and high quality PEDOT PSS films can be readily prepared through solution processing . In addition PEDOT PSS is highly transparent in the visible range and has excellent thermal stability . Nevertheless PEDOT PSS has a problem of low conductivity . The as prepared PEDOT PSS films from its aqueous solution have a conductivity of lower than 1Scm 1 which severely impedes the application of PEDOT PSS in various aspects . It has been discovered that the conductivity of as prepared PEDOT PSS from its aqueous solution can be significantly enhanced by adding organic compounds like high boiling point polar organic solvents ionic liquids and surfactants or through a post treatment of PEDOT PSS films with organic compounds including high boiling point polar solvents salts zwitterions cosolvents organic and inorganic acids . Conductivity of more than 3000Scm 1 was recently observed on PEDOT PSS films after treated with sulfuric acid . This conductivity is comparable to that of indium tin oxide the conventional transparent electrode material of optoelectronic devices .

This article reviews the methods to enhance the conductivity of PEDOT PSS the mechanisms for the conductivity enhancements and the application of the highly conductive PEDOT PSS films in polymer light emitting diodes and polymer solar cells . 


Summary: PEDOT PSS is promising to be the next generation transparent electrode. This article reviews the secondary doping methods for conductivity enhancement of PEDOT PSS.

Metrics to track seasonal transitions are needed for a wide variety of ecological and climatological applications. Here a MATLAB toolkit for calculating spring indices is documented. The spring indices have been widely used in earlier studies to model phenological variability and change through time across a wide range of spatial scales. These indices require only daily minimum and maximum temperature observations e.g. from meteorological records as input along with latitude and produce a day of year value corresponding to the simulated average timing of first leaf and first bloom events among three plant cultivars. Core functions to calculate the spring indices require no external dependencies and data for running several illustrative test cases are included. Instructions and routines for conducing more sophisticated monitoring and modeling studies using the spring indices are also supplied and documented. 


Summary: Spring indices can be used to characterize spring onset across a wide range of spatial scales. These indices are based on phenological models but can be computed from meteorological data. We present software and documentation for calculating spring indices. Some basic examples of the potential uses and extensions of the spring indices are also shown.
