Computer aided tools of ergonomics and system design

Anthropometric digital human models are well established and used in order to get a better design of human‐adapted machines. By the application of electronics and computer operated machines, nearly arbitrary design of controlling and operating the technical equipment seems possible. So more and more the question arises: What is operable by the human operator and what leads probably to a disaster due to much stress. By applying systems ergonomic rules, this can be avoided to a far extent. In order to consider these rules already in an early state of development, it seems useful to incorporate such rules in digital human models. By this procedure, cognitive human models will be created. The combination of such models with anthropometric digital human models will lead to the possibility to carry out virtual experiments under the condition of computer aided design. So, in the future, more ergonomic knowledge will be considered by this new technique. © 2002 Wiley Periodicals, Inc.
Single-crystal Data of Ternary Germanides RE2Nb3Ge4 (RE = Sc, Y, Gd–Er, Lu) and Sc2Ta3Ge4 with Ordered Sm5Ge4-type Structure

Abstract Small single crystals of the Sm5Ge4-type (space group Pnma) germanides RE2Nb3Ge4 (RE = Sc, Y, Gd-Er, Lu) and Sc2Ta3Ge4 were synthesized by arc-melting of the respective elements. The samples were characterized by powder and single-crystal X-ray diffraction. In all structures, except for Sc2.04Nb2. 96Ge4 and Sc2.19Ta2. 81Ge4, the rare earth and niobium atoms show full ordering on the three crystallographically independent samarium sites of the Sm5Ge4 type. Two sites with coordination number 6 are occupied by niobium, while the slightly larger site with coordination number 7 is filled with the rare earth element. Small homogeneity ranges with RE=Nb and RE=Ta mixing can be expected for all compounds. The ordered substitution of two rare earth sites by niobium or tantalum has drastic effects on the coordination number and chemical bonding. This was studied for the pair Y5Ge4/Y2Nb3Ge4. Electronic structure calculations show larger charge transfer from yttrium to germanium for Y5Ge4, contrary to Y2Nb3Ge4 which shows stronger covalent bonding due to the presence of Nb replacing Y at two sites Graphical Abstract Single-crystal Data of Ternary Germanides RE2Nb3Ge4 (RE = Sc, Y, Gd–Er, Lu) and Sc2Ta3Ge4 with Ordered Sm5Ge4-type Structure
Is syntactic-category processing obligatory in visual word recognition? Evidence from Chinese

Three experiments were conducted to investigate how syntactic-category and semantic information is processed in visual word recognition. The stimuli were two-character Chinese words in which semantic and syntactic-category ambiguities were factorially manipulated. A lexical decision task was employed in Experiment 1, whereas a semantic relatedness judgment task and a syntactic-category judgment task were adopted in Experiments 2 and 3, respectively. A semantic ambiguity disadvantage was observed in all three experiments, whereas a syntactic-category ambiguity disadvantage was only found in Experiment 3. In addition, no significant semantic ambiguity×syntactic-category ambiguity interaction was obtained across the three experiments. These results are consistent with the view that in isolated visual word recognition, the semantic information is crucial, but the syntactic-category information is not, at least in Chinese.
Standard metrics for a plug-and-play tracker

The Motion Imagery Standards Board (MISB) has previously established a metadata "micro-architecture" for standards-based tracking. The intent of this work is to facilitate both the collaborative development of competent tracking systems, and the potentially distributed and dispersed execution of tracker system components in real-world execution environments. The approach standardizes a set of five quasi-sequential modules in image-based tracking. However, in order to make the plug-and-play architecture truly useful we need metrics associated with each module (so that, for instance, a researcher who "plugs in" a new component can ascertain whether he/she did better or worse with the component). This paper proposes the choice of a new, unifying set of metrics based on an informationtheoretic approach to tracking, which the MISB is nominating as DoD/IC/NATO standards.

On the Optimal Step-size Selection for the Alternating Direction Method of Multipliers*

The alternating direction method of multipliers is a powerful technique for structured large-scale optimization that has recently found applications in a variety of fields including networked optimization, estimation, compressed sensing and multi-agent systems. While applications of this technique have received a lot of attention, there is a lack of theoretical support for how to set the algorithm parameters, and its step-size is typically tuned experimentally. In this paper we consider three different formulations of the algorithm and present explicit expressions for the step-size that minimizes the convergence rate. We also compare our method with one of the existing step-size selection techniques for consensus applications.
Project Management: an Evaluation of Software Quality

Abstract Widespread use of microcomputers with the latest project management systems offers a new horizon whose starting point may be located in the 1990s. Therefore an evaluation of software is needed. Here we present a comparative study of a representative sample of packages: CA-Superproject, Instaplan, Micro Planner, Microsoft Project and Project Scheduler, through the evaluation of quality features such as user-friendliness, documentation, resource allocation. A discussion of the performance of this kind of software is included.
Source separation of multichannel acoustic signals measured from living trees

The method in this paper is applied to vibration analysis of the tree trunk. The measured vibrations are believed to provide information about wave coupling and propagation, which may contribute to the detection of decay inside trees. A new signal model is presented and a source separation method using independent component analysis is applied. The aim of the study is to separate the multiple measured signals into independent sources for further analysis. The performance of the method used is investigated using simulated data and real data measured from living trees. The results of simulations validate the proposed method, while the applications justify the signal model, showing that the real multichannel data can be successfully separated into sources similar to harmonic oscillations.
An 8-bit 50+ Msamples/s pipelined A/D converter with an area and power efficient architecture

An efficient architecture for a pipelined A/D converter is described. By sharing amplifiers along the pipeline and also completely eliminating the amplifier from the last stage, an 8-bit converter is realized using just 3 amplifiers (instead of 7 amplifiers with a conventional pipeline architecture). By using two such pipelines in parallel, a sampling rate of over 50 Msamples/s has been achieved in a 0.9-/spl mu/m CMOS technology.
A Research Combining Spatial Filter with Autoregressive Model for EEG Feature Extraction

In a noninvasive brain-computer interface (BCI), EEG feature extraction is a key part for improving classification accuracy and resulting information transfer rate, and it has a crucial and decisive role. In this paper, three different methods were proposed that combine spatial filtering with autoregressive model for EEG feature extraction. Six subjects participated in the BCI experiment during which they were asked to imagine movements of left hand and right hand. Each subject carried out four sessions and each session contained 120 trials. EEG data recordings were used for off-line analysis and the 10 leads around C3 and C4 were chosen for feature extraction. Autoregressive model coefficients and the parameters derived from other three methods were proposed as classification features. Fisher discriminant analysis (FDA) was used as linear classifier. The results show that classification accuracy rates obtained from the three proposed methods are far higher than those acquired from autoregressive model coefficients. At the same time the classification results of each subject are very stable, proving the effectiveness of these novel feature methods.
Social Media and Campaign 2012

Diffusion of innovation theory is used to explain adoption of Facebook in the 2012 campaigns for the U.S. Congress and to identify characteristics that differentiate the small subset of candidates who did not create a Facebook presence from the large majority who did. Models of Facebook adoption for House candidates reveal that there are no differences between Republicans and Democrats. Nonadopters are significantly more likely to be challengers or open-seat candidates, poorly financed candidates, candidates in noncompetitive races, and older. Among nonincumbents, Republicans, and candidates from Republican-oriented districts are more likely to adopt. This study serves as one of the first examinations of social media adoption by congressional candidates in the 2012 elections and discusses relevant developments and trends in adoption since Facebook’s introduction in 2006.
Faceworking: exploring students' education‐related use of Facebook

Social networking sites such as Facebook and MySpace have been subject to much recent debate within the educational community. Whilst growing numbers of educators celebrate the potential of social networking to (re)engage learners with their studies, others fear that such applications compromise and disrupt young people's engagement with ‘traditional’ education provision. With these ongoing debates in mind, the current paper presents an in‐depth qualitative analysis of the Facebook ‘wall’ activity of 909 undergraduate students in a UK university. Analysis of these data shows how much of students' education‐related use of this social networking application was based around either the post‐hoc critiquing of learning experiences and events, the exchange of logistical or factual information about teaching and assessment requirements, instances of supplication and moral support with regards to assessment or learning, or the promotion of oneself as academically incompetent and/or disengaged. With these themes in mind, the paper concludes that rather than necessarily enhancing or eroding students' ‘front‐stage’ engagement with their formal studies, Facebook use must be seen as being situated within the ‘identity politics’ of being a student. In particular, Facebook appears to provide a ready space where the ‘role conflict’ that students often experience in their relationships with university work, teaching staff, academic conventions and expectations can be worked through in a relatively closed ‘backstage’ area.
Systematic Metallaborane Chemistry

Monocyclopentadienyl metal chlorides of transition metals of groups 5−9 react with monoboranes (LiBH4 or BH3THF) to give metallaboranes (and LiCl or BH2Cl). The composition of the metallaborane produced depends on the nuclearity of the metal complex, the number of chlorides (oxidation state of the metal), and the monoborane used. For both monoboranes, a monocyclopentadienyl metal polyborohydride is implicated as the key intermediate, which is competitively converted into either a metal hydride or a metallaborane. The comparative reaction chemistry of these metallaboranes exhibits a dependence on transition metal properties for borane addition, metal fragment addition, and dihydrogen elimination. In addition, base degradation and small molecule reactivity promise similar metal dependencies. These observations suggest that control of borane chemistry with transition metals, analogous to that achieved in organometallic chemistry, can be realized.
Analysis of Japanese compound nouns using collocational information

Analyzing compound nouns is one of the crucial issues for natural language processing systems, in particular for those systems that aim at a wide coverage of domains. In this paper, we propose a method to analyze structures of Japanese compound nouns by using both word collocations statistics and a thesaurus. An experiment is conducted with 160,000 word collocations to analyze compound nouns of with an average length of 4.9 characters. The accuracy of this method is about 80%.
Model-based fault tolerant control reconfiguration for discrete event systems

We describe a novel fault-tolerant approach for discrete-event systems by integrating sensor fusion within a diagnosis and control reconfiguration mechanism. This approach can automatically compute fault-tolerant control/reconfiguration actions which maintain pre-specified control objectives. Our underlying framework is based on model-based diagnostic representations and algorithms, and integrates diagnostics and control reconfiguration for discrete event systems using a single modeling mechanism and suite of algorithms. Given failures in the system, we describe a modeling approach that facilitates diagnostic isolation while performing sensor fusion to minimize false alarms, thereby increasing tolerance to sensor faults as well as (non-measurable) component faults. We show how we can explicitly trade off the false alarm rate with other system constraints.
Supervised Synonym Acquisition Using Distributional Features and Syntactic Patterns

Distributional similarity has been widely used to capture the semantic relatedness of words in many NLP tasks. However, parameters such as similarity measures must be manually tuned to make distributional similarity work effectively. To address this problem, we propose a novel approach to synonym identification based on supervised learning and distributional features, which correspond to the commonality of individual context types shared by word pairs. This approach also enables the integration with pattern-based features. In our experiment, we have built and compared eight synonym classifiers, and showed a drastic performance increase of over 60% on F-1 measure, compared to the conventional similarity-based classification. Distributional features that we have proposed are better in classifying synonyms than the conventional common features, while the pattern-based features have appeared almost redundant.
Technique for real-time frontal face image acquisition using stereo system

Most part of existing systems for face recognition is usually based on two-dimensional images. And the quality of recognition is rather high for frontal images of face. But for other kind of images the quality decreases significantly. It is necessary to compensate for the effect of a change in the posture of a person (the camera angle) for correct operation of such systems. There are methods of transformation of 2D image of the person to the canonical orientation. The efficiency of these methods depends on the accuracy of determination of specific anthropometric points. Problems can arise for cases of partly occlusion of the person`s face. Another approach is to have a set of person images for different view angles for the further processing. But a need for storing and processing a large number of two-dimensional images makes this method considerably time-consuming. The proposed technique uses stereo system for fast generation of person face 3D model and obtaining face image in given orientation using this 3D model. Real-time performance is provided by implementing and graph cut methods for face surface 3D reconstruction and applying CUDA software library for parallel calculation.
Principled Practical Knowledge: Not a Bridge but a Ladder

The much-lamented gap between theory and practice in education cannot be filled by practical knowledge alone or by explanatory knowledge alone. Principled practical knowledge (PPK) is a type of knowledge that has characteristics of both practical know-how and scientific theory. Like basic scientific theory, PPK meets standards of explanatory coherence. However, its main function is not explanation or prediction but practical guidance. PPK grows out of efforts to solve practical problems, but it requires additional effort invested in producing knowledge that goes beyond what is required for the task at hand yet not so far beyond as to be unusable by practitioners. The Wright brothers’ construction of PPK to address problems of flight control is used as a model for building such knowledge in the learning sciences. Design-based research in the learning sciences may motivate research into basic theoretical questions, but it is unlikely to contribute directly to answering them. Extending design-based research to the creation of PPK can, however, increase the generalizability of knowledge produced through design work and provide a ladder leading to sometimes radical design improvement.
Reverse translations of gene-coding DNA sequences using hidden Markov models

This work is aimed to algorithmically (in silico) reproduce the sequence of DNA from protein sequence, i.e. solve protein back-translation problem or reverse translation problem. Presented solution produces a result using hidden Markov models without usage of codon frequency data obtained in other (previous) analysis. Based on biological foundations of protein biosynthesis the Markov model is constructed, then trained with the support of the Viterbi algorithm, and used to estimate the most likely coding sequence. An application that implements the above algorithm is described, the results obtained by this application are studied, and comparison to other solutions of the protein back-translation (reverse translation) problem is presented.
Sparse Recovery Based on Squarewave-Like Sum Function Minimization

For the problem of sparse recovery, an approximation algorithm, termed Squarewave-Like Sum Function Minimization (abr. SLSFM), is proposed. Firstly, norm is appro-ximated by squarewave-like sum function. Then sparse recovery is cast as Squarewave-Like Sum Function Minimization problem, which is solved by a fast iterative method. Finally, simulation results show that our algorithm has some advantages over most existing methods: it is more robust to noise and needs less measurement.
The time-reversal technique re-interpreted: subspace-based signal processing for multi-static target location

The time-reversal field processing technique for active remote sensing is re-interpreted in the conceptual framework of subspace-based signal processing. Though both of these subjects have a long and extensive history, we believe that our work is the first to relate these two rather different signal processing approaches. The concept at the heart of both approaches is the multi-static frequency response matrix (FRM) of the active antenna array. It is a function of array/scatterer geometry (via a suitable Green function) and of the scatterers' reflection coefficients. The time-reversal technique locates the most reflective target by determining the largest singular value of the FRM and the corresponding (right) singular vector. Consequently, it performs well only when the scatterers are "well-resolved," i.e., when the Green function vectors used in forming the FRM are approximately orthogonal to each other. In contrast, we show that subspace-based signal processing can be successfully used even when the targets are not "well-resolved. " Moreover, the performance of our subspace-based schemes can be further enhanced by using wideband signals and combining FRM information from multiple frequencies. The coupling of time-reversal field processing with subspace methods leads to a powerful approach for locating targets under arbitrary wave-propagation conditions (both near-field and far-field), including arbitrary non-homogeneous media and arbitrary geometries.
On the influence of correlated Rayleigh-fading channel with capture over IEEE 802.11 WLANs

Considering the flat Rayleigh-faded channel, we derived an analytical expression for the frame capture probability P/sub capture/ assuming two discrete mean power levels (occurring with predefined probability) of frames at the receiver. The simulations prove the validity of such a capture model assuming 24 dB difference of the two power levels. The expected through improvement under capture is observed only given the RTS/CTS "handshake" transmission scheme is not used. The impact of different lengths of frame-error bursts due to correlated channel fading over performance can be neglected.
Predictor Adaptive Differential Pulse Code Modulation (DPCM)

Many ideas have recently been proposed on the Adaptive DPCM (ADPCM) scheme. The most promising of these is a scheme of adaptively changing prediction function. The authors have studied the prediction function characteristics of television (TV) signals and developed a new Adaptive DPCM algorithm called Predictor Adaptive DPCM, which is based on the spatial correlation characteristics of the prediction function. In our algorithm, the prediction function at the coding sample position is decided by calculating and comparing prediction errors given by various prediction functions at the neighboring, already coded, sample position (called the reference sample position). This algorithm achieves 40%-16% reduction of the transmission bit rate compared to conventional DPCM schemes. This paper describes the spatial correlation characteristics of the prediction function, an algorithm for adaptively changing prediction functions, selection of the optimum reference sample position and selection of the optimum prediction function combination. Computer simulation results of the new algorithm using the moving videotelephone signals, and comparisons between our algorithm and conventional DPCM schemes are also described.
