Discrimination of emotion from movement and addition of emotion in movement to improve human-coexistence robot's personal affinity

This paper presents the result of trials of the discrimination of emotion from movement and the addition of emotion in movement on a teddy bear robot, aiming at both expressing a robot's emotion by movement and improving a robot's personal affinity. We addressed four kinds of emotion -joy, anger, sadness, and fear. In this research, two standpoints were considered - a performer and an observer - to establish the data of emotional movement used for analysis. The data of movement were collected as a performer's standpoint and they were sorted out in an observer's standpoint. In discriminating the emotion included in movement from the data of movement, both the method using Laban's feature quantity and the method using principal component analysis were tried. By the discrimination using principal component analysis, about 70% of rate of correct discrimination was obtained on all the four emotions. The feature of movement that each emotion could be interpreted was presumed from the coefficient of the discrimination function obtained in the discrimination using principal component analysis. Using the obtained feature the design principle of movement to add emotion into a basic movement was defined. From the verification experiment, it was suggested that the movement which people can interpret the intended emotion with relatively high probability would be produced about joy and anger. About fear and sadness, since the movement to express those emotions has small and little motions, it would be difficult to distinguish the feature and to produce clear emotional movement.
Approximate formulae approach for efficient inductance extraction

In this paper, we present a new and effective approach to the extraction of on-chip inductance, in which we apply approximate formulae. The equations are based on the assumption of filaments or bars of finite width and zero thickness and are derived through Taylor's expansion of the exact formula for mutual inductance between filaments. Despite the assumption of uniform current density in each of the bars, the model is sufficiently accurate for the interconnections of current and future LSIs, in which most of the wires are not affected by the skin and proximity effects. Expression of the equations in polynomial form provides a balance between accuracy and computational complexity. These equations are mapped according to the geometric structures for which they are most suitable in minimizing runtime in the calculation of inductance while remaining accurate to within 3%. Within the geometrical constraints, the wires are of arbitrary specification. From a comprehensive evaluation on the ITRS-specified global wiring structure for 2003, the values for inductance extracted through the proposed approach are within 3% of the values obtained by commercial three-dimensional (3-D) field solvers. The efficiency of the proposed approach is also demonstrated by extraction from a real layout design that has 300-k interconnecting segments.
Reconfiguration of shipboard power system using discrete particle swarm optimisation

Reconfiguration of shipboard power system is a typical non-linear discrete optimisation problem. A model of shipboard power system is established. Discrete particle swarm optimisation (DPSO) is used to solve reconfiguration problem. The result of simulation shows that DPSO can reconfigure shipboard power system efficiently.
Consideration of the oxide particle–dislocation interaction in 9Cr-ODS steel

Abstract The interaction between oxide particles and dislocations in a 9Cr-ODS ferritic steel is investigated by both static and in situ TEM observation under dynamic straining conditions and room temperature. The measured obstacle strength () of the oxide particles was no greater than 0.80 and the average was 0.63. The dislocation loops around some coarsened particles were also observed. The calculated obstacle strength by a stress formula of the Orowan interaction is nearly equaled to the average experimental value. Not only cross-slip system but also the Orowan interaction should be considered as the main interaction mechanism between oxide particles and dislocation in 9CrODS ferritic steel.
Soft and flexible antennas on permittivity adjustable PDMS substrates

This work presents novel techniques for producing substrates for flexible antennas. The technique we propose is based on the use of an already existing and widely used substrate material Polydimethylsiloxane (PDMS), where the dielectric properties of the substrate are adjusted by loading the PDMS with low or high permittivity inclusions. The low adhesion characteristics of PDMS are overcome by immersing the conducting parts of the antenna inside the substrate, at the same time sealing the antenna against the influence of dust, or water. A patch antenna prototype is realized and characterized. The built antenna is soft and flexible and it shows good radiation characteristics in terms of input matching and total gain. Measurements are in a good compliance with the simulation results.
Global delay optimization using structural choices

This paper presents a fast global method for delay optimization after technology mapping. Timing analysis is used to identify timing-critical areas in the mapped network where new structures are synthesized to favor late-arriving signals. Unlike previous methods that make incremental local changes to the mapped network, the proposed method records many alternative structures and defers the final decision to the technology mapper. Experimental results for networks mapped into 6-input look-up tables (6-LUTs) show that the delay is, on average, improved 14% using a realistic delay library for LUTs with variable-pin delays and wire-delay estimation. The area penalty after the delay optimization is about 2% and can be eliminated by area-oriented resynthesis. When the algorithm is compared with DAOmap, the experimental results show 27% logic level reduction while the area is increased by only 1%. The algorithm is also fast and applicable to very large networks. The runtime of the proposed algorithm is 16x and 3x faster than DAOmap for large industrial and academic designs, respectively.
Oriented columnar films of a polar 1,2,3-triazole-based liquid crystal prepared by applying an electric field

We report the electric-field (E-field)-assisted orientation of a bent-core liquid crystal (LC) based on the polar 1,2,3-triazolyl group. The LC exhibited a hexagonal columnar (COLhex) phase at ambient temperature, which transformed into a disordered columnar (COLdis) phase with short-range correlation upon heating. Dielectric relaxation spectroscopy and switching studies revealed that the aromatic cores could undergo in-plane rotation (α-relaxation) in the COLhex phase, while R-relaxation allowing the reorientation of the triazolyl units along the E-field direction occurred in the COLdis phase. Infrared spectroscopy confirmed that the hydrogen-bonding interactions between triazolyl units along the columnar axis affected the molecular motion. Based on the dynamics studies, two columnar alignment methods under E-fields, i.e., an isothermal method in the COLhex phase and a cooling method from the COLdis to COLhex phase were examined. Both methods give high-quality oriented columnar thin films. In particular, the cooling method requires less time (only 1 min) and a weaker E-field (10 V μm−1), and therefore, it could be applied to the alignment of a bulk-level film (thickness: 260 μm). The successful orientation could be verified by in situ X-ray diffraction analysis under an E-field. The current–voltage curves before and after the alignment indicated that the orientation process enhanced electric conduction.
Fuel Properties of Woody Biomass from Pruning Operations in Fruit Orchards

Biomass has become a major source of renewable energy. The basic fuel properties of woody biomass from orchards were evaluated on the following fruit tree wood obtained from pruning operations: ‘Reliance’ peach, ‘Burlat’ cherry, ‘Packham’s Triumph’ pear, ‘Early Geneva’ apple, hazel (Polish variety Halle), ‘Hargrand’ apricot, walnut, domestic plum (Polish variety Wegierka), and sour cherry (variety Ujfehertoi furtos). The research included the wood and bark of the trunk, whole limbs, and branches. Gross calorific value for the majority tested biomass ranged from 19.2 to 21.3 MJ / kg, which is typical for wood and bark of broadleaf species. The low content of chlorine and sulfur in the analyzed samples would contribute to low corrosion in boilers and a low atmospheric pollution factor for generated sulfur oxides and hydrogen chloride. Properties of fuel biomass obtained from pruning operations were not noticeably different from the typical properties of solid biofuels derived from woody forest biomass. Based on these results, biomass from orchards can be a substitute for raw forest material suitable for energy use.
Evaluating Kidney Function in Elderly Population: A Cross-Sectional Study in Primary Health Care

Background: Chronic kidney disease (CKD) is an important condition, with implications in morbidity and mortality that primary care physicians should early detect. The aim of this study was to identify the prevalence of CKD among the elderly population in primary care settings and to investigate the extent to which serum creatinine reflects kidney function. Methods: All the patients aged 65 years old and over who came for laboratory tests in an urban primary health center for six months were invited to participated. Additional data on their age, gender, body weight (kg) and their medical history on chronic diseases were collected. The Cockcroft-Gault equation was used for the estimation of the participants' kidney function. Results: 325 patients participated in the study with mean age 73.9 years old (±6.0, min 65-max 91), out of which 146 male (44.9%). According to the estimated creatinine clearance, which in turn estimates glomerular filtration rate (GFR) in ml/min, eGFR: 60-89 was found in 50.5% (164), eGFR: 30-59 in 26.2% (85) and eGFR: 15-29 in 2.2% (7). Spearman's correlation coefficient (rho0 between age and eGFR was -0.52, p<0.001. Serum creatinine (mg/dl) was ranging from 0.7 to 1.7 (mean 1.1) in patients with eGFR: 30 ml/min to 59 ml/min and 1.6 to 3.2 (mean 2.1) in the group with eGFR: 15 ml/min to 29 ml/min. Conclusion: General practitioners should routinely estimate kidney function in their in the older patients. Since the normal serum creatinine reference interval does not necessarily reflect a normal kidney function, GFR equations may facilitate its estimation in every day practice. Early identification of CKD, dosage reduction of renally excreted drugs and timely referral to a nephrologist is feasible and should be pursued within primary care.
Larval Helicoverpa zea Transcriptional, Growth and Behavioral Responses to Nicotine and Nicotiana tabacum

The polyphagous feeding habits of the corn earworm, Helicoverpa zea (Boddie), underscore its status as a major agricultural pest with a wide geographic distribution and host plant repertoire. To study the transcriptomic response to toxins in diet, we conducted a microarray analysis of H. zea caterpillars feeding on artificial diet, diet laced with nicotine and Nicotiana tabacum (L.) plants. We supplemented our analysis with growth and aversion bioassays. The transcriptome reflects an abundant expression of proteases, chitin, cytochrome P450 and immune-related genes, many of which are shared between the two experimental treatments. However, the tobacco treatment tended to elicit stronger transcriptional responses than nicotine-laced diet. The salivary factor glucose oxidase, known to suppress nicotine induction in the plant, was upregulated by H. zea in response to tobacco but not to nicotine-laced diet. Reduced caterpillar growth rates accompanied the broad regulation of genes associated with growth, such as juvenile hormone epoxide hydrolase. The differential expression of chemosensory proteins, such as odorant binding-protein-2 precursor, as well as the neurotransmitter nicotinic-acetylcholine-receptor subunit 9, highlights candidate genes regulating aversive behavior towards nicotine. We suggest that an observed coincidental rise in cannibalistic behavior and regulation of proteases and protease inhibitors in H. zea larvae signify a compensatory response to induced plant defenses.
Gene marking of human neural stem/precursor cells using green fluorescent proteins

Ex vivo gene therapy and cell replacement in the nervous system may provide therapeutic opportunities for neurodegenerative disorders. The development of optimal gene marking procedures for human neural stem cells (hNSCs) is crucial for the success of these strategies, in order to provide a correct understanding of the biology of transplanted cells.
From continuous improvement to continuous innovation: a (retro)(per)spective

The new name of the industrial game is continuous innovation. But what is continuous innovation? And how can we manage and organise for it? This article addresses these questions by, first of all, defining continuous innovation as the ability to combine operational effectiveness and strategic flexibility - exploitation and exploration - capabilities that have traditionally been regarded as antithetical. Next, an old debate between organisation theorists on the question of whether it is at all possible to combine the two capabilities in one system is summarised to conclude that the majority of scholars argue that it is difficult, perhaps even impossible, to achieve continuous innovation. However, some authors have challenged this stance and have provided some useful thoughts, though little empirical evidence, as to how operational effectiveness and strategic flexibility can be combined to produce continuous innovation. The question of how empirically supported knowledge could be developed is approached firstly by briefly discussing the bodies of theory underlying the current thinking about continuous innovation, namely organisational theories of innovation, learning, and continuous improvement. Then, the papers presented at the 1995, 1998 and 2000 (Euro)CINet conferences will be analysed to show how these fields are gradually converging into what would more appropriately be labelled continuous innovation (instead of improvement). The analysis also shows that the field has a couple of serious weaknesses that need to be addressed if the research community involved really wants to contribute to the art and science of continuous innovation. The paper concludes with a summary of this analysis, presented as an agenda for further research.
Complex decision rules in categorization : contrasting novice and experienced performance

not b e easily verbalized. Therefore, this article focuses on nonlinear decision rules in perceptual categorization that have no simple verbal description. Some studies have focused on such categorization problems (e.g., Medin & Schwanenflugel, 1981; Nosofsky, 1986, 1987, 1989; Shepard & Chang, 1963; Wattenmaker, Dewey, Murphy, & Medin, 1986). In these experiments, however, many different nonlinear decision rules predicted the same categorization accuracy. Therefore, although i t was shown that subjects did use a nonlinear rule, the design of the experiments made it impossible to determine exactly which of the many nonlinear rules were used. The present studies extend this line of research in several respects. We use an experimental design in which unique decision rules lead t o unique patterns of responding. This makes i t possible t o identify uniquely a subject's decision rule. '

Minimum-time sliding mode control for second-order systems

Our approach for near time-optimal control is based on Takagi-Sugeno fuzzy model of the maximum slope SMC sliding surface as an adaptive technique for tuning the current slope of the sliding surface to the maximum feasible slope depending on the current state of system. The stability conditions of this method are proved and respective measures about the feasible maximum slope are presented. Experimental results demonstrate the system behaviour.
The Effect of Emotion Regulation Training on Occupational Stress of Critical Care Nurses.

INTRODUCTION Occupational stress is a common, serious and costly health problem in work environment. Nursing is a very stressful job high level of stress in this job affects nurses' physical and mental health. AIM To investigate the effect of emotion regulation training of occupational stress on critical care nurses in two teaching hospitals in Sanandaj, Iran. MATERIALS AND METHODS This interventional study was conducted on 60 nurses working in the Intensive Care Unit (ICU) and Critical Care Unit (CCU) in two teaching hospitals in Sanandaj, Iran. Data were collected using Expanded Nursing Stress Scale (ENSS) questionnaire. The questionnaire in both intervention and control groups before and after the training sessions of emotion regulation training were completed. Data were analysed using SPSS Version 20. Statistical indices such as frequency, percentage, mean and standard deviation and also t-test, Chi-square test and paired t-test were used. RESULTS Mean occupation stress score in the intervention group before emotion regulation training was 136.6±24.6 and after training was 113.02±16.2 (p = 0.001). Occupational stress dimensions including; conflict with physicians, problems with peers, workload, uncertainty concerning treatment and problems related to patients and their families in the intervention group compared with the control group was statistically significant (p <0.05). CONCLUSION Emotion regulation training is effective in reducing occupation stress of critical care nurses.
The UWB Summariser at Multiling-2013

The paper describes our participation in the Multi-document summarization task of Multiling-2013. The community initiative was born as a pilot task for the Text Analysis Conference in 2011. This year the corpus was extended by new three languages and another five topics, covering in total 15 topics in 10 languages. Our summariser is based on latent semantic analysis and it is in principle language independent. Its results on the Multiling-2011 corpus were promising. The generated summaries were ranked first in several languages based on various metrics. The summariser with minor changes was run on the updated 2013 corpus. Although we do not have the manual evaluation results yet the ROUGE-2 score indicates good results again. The summariser produced best summaries in 6 from 10 considered languages according to the ROUGE-2 metric.
Full Resolution Lightfield Rendering

Lightfield photography enables many new possibilities for digital imaging because it captures both spatial and angular information, i.e., the full four-dimensional radiance, of a scene. Extremely high resolution is required in order to capture four-dimensional data with a two-dimensional sensor. However, images rendered from the lightfield as projections of the four-dimensional radiance onto two spatial dimensions are at significantly lower resolutions. To meet the resolution and image size expectations of modern digital photography, this paper presents a new technique for rendering high resolution images from the lightfield. We call our approach full resolution because it makes full use of both positional and angular information available in captured radiance data. We present a description of our approach and an analysis of the limits and tradeoffs involved. We demonstrate the effectiveness of our method experimentally by rendering images from a 542 megapixel lightfield, using the traditional approach and using our new approach. In our experiments, the traditional rendering methods produce a 0.146 megapixel image, while with the full resolution approach we are able to produce a 106 megapixel final image.

Effects of N-Acetylglucosamine and α-methylglucoside on bacteriophage T 4 adsorption to Escherichia coli B 23

The role of lipopolysaccharide in the receptor function for bacteriophage T4 was studied by using Escherichia coli K-12 B23 strain. The receptor activity for T4 was monitored by inhibiting phage adsorption by saccharides that mimic sugars located at the receptor site on LPS. Coliphage T4 adsorbed to intact cells and acetone-ether treated cells, but was not adsorbed to heat-treated cells. The adsorption of phage T4 to acetone and ether-treated cells was inhibited by glucose derivatives like N-acetylglucosamine and α-methylglucoside but was not inhibited by maltose. The inhibition effect of the N-acetylglucosamine and αmethylglucoside is consistent with the observation that T4 adsorbs to the two glucoses on Cterminus of LPS’s R-core in E. coli B23. However, wild type T4 is also capable of absorbing to E. coli B23 via OmpC, a major outer membrane protein, and phage adsorption via this protein might influence results obtained. With this confounding factor, a conclusion cannot be stated confidently until the adsorption is simplified by using OmpC mutants or OmpC E. coli.
Adaptive Dynamic Surface Control for Uncertain Nonlinear Systems With Interval Type-2 Fuzzy Neural Networks

This paper presents a new robust adaptive control method for a class of nonlinear systems subject to uncertainties. The proposed approach is based on an adaptive dynamic surface control, where the system uncertainties are approximately modeled by interval type-2 fuzzy neural networks. In this paper, the robust stability of the closed-loop system is guaranteed by the Lyapunov theorem, and all error signals are shown to be uniformly ultimately bounded. In addition to simulations, the proposed method is applied to a real ball-and-beam system for performance evaluations. To highlight the system robustness, different initial settings of ball-and-beam parameters are considered. Simulation and experimental results indicate that the proposed control scheme has superior responses, compared to conventional dynamic surface control.
Calibration of IQ imbalance in OFDM transceivers

High rate wireless communication systems require the design of low-cost radio transceivers with low power consumption. The design of direct conversion receivers, which convert the radio frequency directly to baseband, has thus been the subject of active investigation in recent years. However, such architectures introduce certain design challenges of their own, namely DC offsets as well as gain and phase mismatches in the in-phase and quadrature paths. In this paper, we propose novel methods for calibrating the IQ imbalance in the receiver for OFDM communication systems. Relations are derived for the estimation of the gain and phase parameters for AWGN as well as frequency selective fading channels. We will also investigate the statistical properties of the estimated parameters. The calibration procedure is verified for an OFDM system designed based on the IEEE 802.11a standard for wireless local area networks.
