Horizontal Forces on Crane Runway Caused by Skewing of the Crane

Horizontal forces between the crane and the crane runway girder occur during a motion of an overhead travelling crane on the crane runway. These forces can be caused by skewing, acceleration or braking of the crane. As a result of these forces wear of wheel rims can occur and drive ability of overhead crane can get worse. There are several procedures for determination of these horizontal loads varying both in physical model and magnitude of forces. Historically, these procedures have been developed. The first methods were based on empirical bases and experiences. The main problem of determining of these forces is a large number of factors which affect a magnitude of these horizontal forces. These factors are in addition difficult to describe, to measure etc. However, with the increasing possibilities of science and technology some methods based on a scientific and experimental basis were developed. This paper summarizes some of the methods used in past and in present and also show possibility to calculate the horizontal forces between crane runway and the overhead crane by dynamic model.
Spontaneous evolution of linguistic structure-an iterated learning model of the emergence of regularity and irregularity

A computationally implemented model of the transmission of linguistic behavior over time is presented. In this iterated learning model (ILM), there is no biological evolution, natural selection, nor any measurement of the success of the agents at communicating (except for results-gathering purposes). Nevertheless, counter to intuition, significant evolution of linguistic behavior is observed. From an initially unstructured communication system (a protolanguage), a fully compositional syntactic meaning-string mapping emerges. Furthermore, given a nonuniform frequency distribution over a meaning space and a production mechanism that prefers short strings, a realistic distribution of string lengths and patterns of stable irregularity emerges, suggesting that the ILM is a good model for the evolution of some of the fundamental features of human language.
An Intention-Aware Interactive System for Mobile Video Browsing

Video browsing describes an interactive process where the user wants to find a target shot in a long video. Therefore, it is crucial for a video browsing system to be fast and accurate with minimum user effort. Previously, video browsing systems suffered from either lots of user efforts or heavy computation cost, which makes them less effective. We propose an RNN-based \textit{intention-aware} system to overcome these limitations. At each interactive round, the user only needs to select one of the displayed shots that is most visually similar to her mental target and then the user's choice will further tailor the search to the target. The search model update merely requires vector inner products which means the system is highly responsive.
Towards Efficient Horizontal Multimedia Database Fragmentation using Semantic-based Predicates Implication

Partitioning techniques are traditionally used in distributed system design to reduce accesses to irrelevant information by grouping data frequently accessed together in specific fragments. Here, we address the primary horizontal fragmentation of textually annotated multimedia data. In this study, we discuss the issue of identifying semantic implications between textual-based multimedia predicates, as a crucial phase in the efficient partitioning of multimedia data. Our proposal integrates knowledge bases as a framework for assessing the semantic relatedness between predicate values and operators. We developed a prototype implementing the various aspects of multimedia semantic predicates implications. Experimental results show that the proposed method is polynomial in the number of user predicates as well as the sizes of the knowledge bases being employed. Realworld multimedia fragmentation tests are ongoing.
The Authenticity of Perception of the Visitors to the Archaeological Festival at Biskupin

The article concerns the importance of the authenticity for the satisfaction of tourists visiting tourist attractions. The study was conducted among visitors to the 15th Archaeological Festival at Biskupin (N = 400). Three types of authenticity were distinguished: the objectivist, constructivist and the existential one, as well as their impact on the quality of experience, satisfaction and behavioural intentions of people visiting the festival were studied. The path analysis results show that satisfaction is directly influenced by existential authenticity, while the strongest relation with the quality of experience has the objectivist authenticity. Furthermore, the perception of all three types of authenticity has a significant influence on behavioural intentions of tourists in relation to the attractions. This impact, depending on the type of authenticity has a different course: the objectivist and constructivist authenticity influences the intentions directly, while the existential authenticity has an impact also through the influence on the quality of experience and satisfaction.
Why Are Electronic Invoice Processes Risky? - Empirical Analysis and Discussion of Risk Factors

Electronic invoice processes are characterized by various software solutions, legal uncertainty, heterogeneous demands, lack of know how, and information system infrastructure incompatibilities. Due to this complexity and the uncertainty that companies face, a holistic map of risk factors of e-invoice processes is required. Companies must be conscious not only about potential opportunities but also about potential risks before they change their business processes and their information systems’ architecture. Potential risk factors are identified theoretically and empirically evaluated with a quantitative expert survey that investigates risk probabilities and potential losses associated with these factors. The empirical analysis reveals that the investigated factors are valid and reliable. After conducting an explorative factor analysis, 37 statistically significant risk factors are grouped into ten risk dimensions: process organization, standard, environment, project management, strategy, acceptance, system, process execution, security, and change management.
The Role of Quasi-identifiers in k-Anonymity Revisited

The concept of k-anonymity, used in the recent literature to formally evaluate the privacy preservation of published tables, was introduced based on the notion of quasi-identifiers (or QI for short). The process of obtaining k-anonymity for a given private table is first to recognize the QIs in the table, and then to anonymize the QI values, the latter being called k-anonymization. While k-anonymization is usually rigorously validated by the authors, the definition of QI remains mostly informal, and different authors seem to have different interpretations of the concept of QI. The purpose of this paper is to provide a formal underpinning of QI and examine the correctness and incorrectness of various interpretations of QI in our formal framework. We observe that in cases where the concept has been used correctly, its application has been conservative; this note provides a formal understanding of the conservative nature in such cases.
A Time to Be Born: Birth Seasonality in Sub-Saharan Africa

Introduction: Despite our ability to breed continuously, almost all human populations exhibit seasonal variation in reproduction. Knowledge of these seasonal birth patterns gives insight into drivers of human fertility, the influence of birth month on later life outcomes, and can help us characterize the seasonal dynamics of many childhood infectious diseases. Seasonality of births has been extensively studied in North America, Europe, and East Asia but less so in African settings. This paper is the first to systematically test for and document birth seasonality in Sub-Saharan Africa (SSA). Data and Methods: Birth data from Demographic and Health Surveys are aggregated by country and ecological zone. The monthly time series of births are then de-tended and converted to monthly amplitude. Amplitude is defined as the percent deviation from the annual monthly mean. We then calculate the periodicity of the monthly birth amplitude time series using Fourier spectral analysis. We also measure seasonality using Ordinary Least Square regression. Results: We find that births are indeed seasonal with a few exceptions. However we find large variation in the amplitude (from five percent to 65 percent) and pattern (unimodal, bimodal . . . ) across regions. We also look at birth seasonality across ecological zones. Finally where possible we disaggregate the data and look at birth seasonality across maternal characteristics such as mother’s education level, type of residence (e.g., rural or urban), and religion.

Nonstandard Employing Knowledge Worker's Organizational Citizenship Behavior: A Comparative Research Based on Different Employment Types

Recent years, nonstandard employment has been coming an important method for organization to increase its flexible ability. Especial the nonstandard employing knowledge workers have been the vital part of organization's core competition. However nonstandard employing knowledge workers have different features and working context comparing with standard employing knowledge workers, which will affect their Organizational Citizenship Behavior (OCB) that is important attitude and behavior available to organizational performance. This research investigates the difference between standard and nonstandard employment knowledge worker's OCB and among different nonstandard employment types by empirical study. The results show the standard employment knowledge workers' OCB are higher than nonstandard employee's generally, and among the nonstandard employment types, the OCB are different.
Recent natural hybridization between two allopolyploid wheatgrasses (Elytrigia, Poaceae): ecological and evolutionary implications.

BACKGROUND AND AIMS Natural hybridization was investigated between two predominantly allohexaploid wheatgrasses, weedy Elytrigia repens and steppic E. intermedia, with respect to habitats characterized by different degrees of anthropogenic disturbance. METHODS Using flow cytometry (relative DNA content), 269 plants from three localities were analysed. Hybrids were further analysed using nuclear ribosomal (ITS1-5.8S-ITS2 region) and chloroplast (trnT-F region) DNA markers in addition to absolute DNA content and chromosome numbers. KEY RESULTS Weedy E. repens was rare in a steppic locality whereas E. intermedia was almost absent at two sites of agricultural land-use. Nevertheless, hybrids were common there whereas none were found at the steppic locality, underlining the importance of different ecological conditions for hybrid formation or establishment. At one highly disturbed site, > 16 % of randomly collected plants were hybrids. Hexaploid hybrids showed intermediate genome size compared with the parents and additive patterns of parental ITS copies. Some evidence of backcrosses was found. The direction of hybridization was highly asymmetric as cpDNA identified E. intermedia as the maternal parent in 61 out of 63 cases. Out of nine nonaploid cytotypes (2n = 9x = 63) which likely originated by fusion of unreduced and reduced gametes of hexaploids, eight were hybrids whereas one was a nonaploid cytotype of E. repens. The progeny of one nonaploid hybrid demonstrated gene flow between hexaploid and nonaploid cytotypes. CONCLUSIONS The results show that E. repens and E. intermedia frequently cross at places where they co-occur. Hybrid frequency is likely influenced by habitat type; sites disturbed by human influence sustain hybrid formation and/or establishment. Hexaploid and nonaploid hybrid fertility is not negligible, backcrossing is possible, and the progeny is variable. The frequent production of new at least partially fertile cyto- and genotypes provides ample raw material for evolution and adaptation.
Complex neonatal hemoglobin pattern due to co‐inheritance of Hb Q‐Thailand and Hb E

Hemoglobinopathies (HbP) are becoming more and more frequent in nonendemic Western countries due to the massive immigration of people coming from highincidence areas. This is a new challenge for first-line laboratories and has led to the inclusion of the hemoglobinopathies into the Dutch newborn screening program (NBS) in 2007. The screening program is using dry blood collected from the heel during the first week after birth and measurement of the normal and abnormal hemoglobin fractions on high-performance liquid chromatography (HPLC). The common hemoglobin variants (Hb S, C, E, and D) are detected at 100% sensitivity in patients and carriers, as well as rare abnormal hemoglobin variants. Specificity is only high for the common variants, simply because these are the most frequent ones in the population. Little is known about the incidence of rare alphachain variants as the Dutch NBS program only reports sickle cell disease, beta-thalassemia major, HbH disease, and carriers of HbS or alpha-thalassemia [1]. No official numbers are available for the rare alpha-chain variants. Nevertheless, common and uncommon variants need both molecular confirmation, in particular when prognosis, genetic risk, and state-of-the art treatment must be assessed. We report the youngest son of a Dutch family of five. The proband from Cambodian origin was referred to the pediatrician after an abnormal NBS result was observed. Repeated HPLC analysis revealed over eight different hemoglobin fractions, indicative for a coexistence of both alphaand beta-globin chain variants and alpha-thalassemia. Molecular analysis revealed the presence of two different mutations in the alphaand beta-globin gene, respectively, producing a thalassemia minor phenotype. Analysis of the hematologic parameters was performed using an automated blood cell counter (Advia 2120i, Siemens). Hemoglobin variants were analyzed with highperformance liquid chromatography (HPLC, Shimadzu) using a PolyCAT ATM column. In addition, to distinguish overlapping peaks, a second different HPLC method was used (variant 2; Bio-Rad Laboratories, Hercules, CA,
Are both the knees of the same size? Analysis of component asymmetry in 289 bilateral knee arthroplasties

Background: Variations in the anatomy of knee are well described, however the true incidence of component asymmetry in bilateral total knee arthroplsties is rarely reported. Incidence of component asymmetry in bilateral total knee arthroplasties (TKA) was retrospectively analysed in 289 cruciate retaining total knee arthroplasties. Materials and Methods: Medical records of these 289 patients were evaluated for the incidence of asymmetry of either femoral or tibial components. Clinical outcomes were compared between the cases of asymetrical components to that of symmetrical components. Results: Incidence of femoral component asymmetry was found to be 9.2% and tibial component asymmetry to be 8.7%. Of 289 cases, TKA 178 were done in a single day (group A), while 111 were done at 2- to 3-day intervals (group B). Asymmetric and symmetric knees were equally distributed among both groups, male and female patients in both groups, and the incidence of component asymmetry was similar between all four different implants–Optetrak-CR (Exactech, Gainesville, FL, USA), Nexgen-CR (Zimmer, Warsaw, IN, USA), PFC-Sigma CR (DePuy, Warsaw, IN, USA), Genesis II CR (Smith and Nephew, Memphis, TN, USA) we used. The pre- and postoperative range of motion and pre- and postoperative knee society scores were compared between the symmetric and asymmetric cases in both the groups and the difference was found to be insignificant. Conclusion: We conclude that incidence of component asymmetry in bilateral total knee arthroplasty is around 9 % and independent sizing of both knees during bilateral arthoplasty is recommended rather than simply relying on the contralateral knee measurements.
Performance analysis of permanent magnet machines considering magnetic losses based on analytical parameter estimation

This paper deals with performance analysis of a permanent magnet generator (PMG) considering magnetic losses using d-q axis and equivalent circuit (EC) model based on analytical parameter estimation. Electrical parameters and magnetic power losses are estimated and calculated by analytical methods, respectively. Derived electrical parameters and magnetic losses are employed for the d-q axis and EC model for the prediction of the performance of the PMG. All analysis results are validated by nonlinear finite element analysis (FEA).
Multilinear subspace analysis of image ensembles

Multilinear algebra, the algebra of higher-order tensors, offers a potent mathematical framework for analyzing ensembles of images resulting from the interaction of any number of underlying factors. We present a dimensionality reduction algorithm that enables subspace analysis within the multilinear framework. This N-mode orthogonal iteration algorithm is based on a tensor decomposition known as the N-mode SVD, the natural extension to tensors of the conventional matrix singular value decomposition (SVD). We demonstrate the power of multilinear subspace analysis in the context of facial image ensembles, where the relevant factors include different faces, expressions, viewpoints, and illuminations. In prior work we showed that our multilinear representation, called TensorFaces, yields superior facial recognition rates relative to standard, linear (PCA/eigenfaces) approaches. We demonstrate factor-specific dimensionality reduction of facial image ensembles. For example, we can suppress illumination effects (shadows, highlights) while preserving detailed facial features, yielding a low perceptual error.
In-home telehealth clinical interaction using a robot

Providing healthcare in remote locations can prove to be costly. Using a static videoconference system in the patient's home has its limitations. A remotely operated mobile robot platform could provide a better interaction with the patient located at home. This paper presents Telerobot, a teleoperated mobile robotic platform equipped with videoconferencing capabilities. Developed by a team of roboticists and clinical experts, the system is designed specifically for the provision of in-home telerehabilitation services. A usability study was done in order to qualify the robot user control scheme and the clinician-patient interaction.
Algorithm Simplification through Object Orientation

The object‐oriented (O‐O) approach is claimed to have a number of advantages. Some support to these claims appeared during an O‐O redesign of a legacy CAD system. A surprisingly simple and efficient solution algorithm was discovered for a change propagation problem. The analysis of the case employs the new concepts of implementation and extension complexity, which indicate the amount of code (software costs) required for the implementation and for later extensions. These two complexities are functions of the problem complexity, expressed by the number N of object types employed to model the problem domain. Moving from the old system to the new O‐O system reduced the implementation complexity from O(N2) to O(N); the extension complexity is reduced from O(N) to O(1). The two systems have the same space and time complexities. The CAD system is employed for designing structures composed of parts. The O‐O analysis attempts to analyse each part type separately, which proved to be possible. The corresponding N different object types can therefore be developed independently of each other. The top down analysis employed for the old algorithm did not discover the simple architecture, because it is not geared to look for this kind of solution. Instead it analyses the N2 different change propagation cases. The methodical search for independent modules is an important reason for preferring O‐O analysis. © 1997 by John Wiley & Sons, Ltd.
How Does a CNN Manage Different Printing Types?

In past OCR research, different OCR engines are used for different printing types, i.e., machine-printed characters, handwritten characters, and decorated fonts. A recent research, however, reveals that convolutional neural networks (CNN) can realize a universal OCR, which can deal with any printing types without pre-classification into individual types. In this paper, we analyze how CNN for universal OCR manage the different printing types. More specifically, we try to find where a handwritten character of a class and a machine-printed character of the same class are "fused" in CNN. For analysis, we use two different approaches. The first approach is statistical analysis for detecting the CNN units which are sensitive (or insensitive) to type difference. The second approach is network-based visualization of pattern distribution in each layer. Both analyses suggest the same trend that types are not fully fused in convolutional layers but the distributions of the same class from different types become closer in upper layers.
The Journal of Biological Chemistry Molecular Cloning and Characterization of a Gene Encoding Pea Cytosolic Ascorbate Peroxidase*

A gene encoding cytosolic ascorbate peroxidase (ApxI) from pea (Pisum sativum L.) was isolated and its nucleotide sequence determined. By homologous alignment between the the genomic clone, positions of introns and exons were determined. The isolated ApxI gene was found to contain 9 introns, the first of which was located within the 6 " untranslated region of the mRNA. Southern blot analysis of pea genomic DNA suggests that in pea cytosolic ascorbate peroxidase is encoded by a single copy gene. Steady state ApxI transcript levels were found to increase in response to several stresses imposed by drought, heat, and application of ethephon, abscisic acid, and the superoxide-generating agent par-aquat. Increases in ascorbate peroxidase activity in response to stresses were less marked than changes observed in transcript levels; cytosolic ascorbate per-oxidase protein levels measured by immunoblot analysis remained unchanged. Ascorbate peroxidase (EC 1.11.1.11) is a hydrogenperoxide-scavenging enzyme, found in higher plants, algae, and some cyanobacteria (1). Functionally and structurally distinct from the typical plant peroxidases superfamily, ascorbate peroxi-dase is unique in having a decided preference toward ascorbate as a reductant (2). Ascorbate peroxidase plays a key role in the removal of hydrogen peroxide in the chloroplasts and cytosol of higher plants (3). The enzyme exists as two distinct isozymes, chloroplastic and cytosolic, both of which catalyze the following reaction. 2 ascorbate + H202 + 2 monodehydroascorbate + 2 HzO The chloroplastic ascorbate peroxidase isozyme was recently purified to homogeneity from tea leaves and compared to the partially purified cytosolic isozyme (2). The two isozymes were found to differ in the following aspects: molecular weight, substrate specificity, pH optimum, and stability. We have recently purified to homogeneity the cytosolic ascorbate per-oxidase from pea shoots (4). Polyclonal antibodies raised The costs of publication of this article were defrayed in part by the payment of page charges. This article must therefore be hereby marked " advertisement " in accordance with 18 U.S.C. Section 1734 solely to indicate this fact. against the purified enzyme were used to isolate a cDNA clone encoding the pea cytosolic ascorbate peroxidase (5). Cytosolic ascorbate peroxidase was found to share little overall homol-ogy with classical plant peroxidases. Significant homology was, however, found in the vicinity of the putative active site with all known peroxidases (5). Although several studies have demonstrated an increase in ascorbate peroxidase activity in response to changes in growth conditions and environmental stresses (6-11), little is known …
