Videobasierte Messung menschlicher Bewegungen konform zum Menschmodell RAMSIS

Im Rahmen dieser Arbeit wurde ein Ansatz unter Verwendung des Menschmodells RAMSIS entwickelt, um auf Basis von Videobeobachtungen, Bewegungen des Menschen dreidimensional zu messen. Ausgehend von biologischen Prinzipien der Bewegungserkennung wurde ein modellbasiertes Verfahren erarbeitet, das  ohne eine Praparierung der Versuchsperson mit Markern  Bewegungen erfassen kann. Das System arbeitet zur Bildgewinnung mit Standardvideotechnik. In die digitalisierten Bildsequenzen wird nach einer Kalibrierung ein individuelles und dreidimensionales Modell projiziert. Dadurch werden Modellbereiche mit Bildbereichen assoziiert und durch Detektieren von Bildveranderungen kann die Bewegung des Probanden in eine Bewegung des Modells uberfuhrt werden. Mit Hilfe dieses Ansatzes konnen konform zum verwendeten Menschmodell Bewegungsdaten ohne physische Beeinflussung des Probanden erhoben werden. Somit wird die Messung ungestorter Bewegungen moglich.
The road from community ideas to organisational innovation: a life cycle survey of idea management systems

This paper introduces a new emerging software component, the idea management system, which helps to gather, organise, select and manage the innovative ideas provided by the communities gathered around organisations or enterprises. We define the notion of the idea life cycle, which provides a framework for characterising tools and techniques that drive the evolution of community submitted data inside idea management systems. Furthermore, we show the dependencies between the community-created information and the enterprise processes that are a result of using idea management systems and point out the possible benefits.
Characterization of novel clonal murine endothelial cell lines with an extended life span

SummaryA murine endothelial cell line was recently established from microvessels that had invaded a subcutaneous sponge implant (Dong, Q. G.; Bernasconi, S.; Lostaglio, S., et al. Arterioscl. Thromb. Vasc. Biol. 17:1599–1604; 1997). From these sponge-induced endothelial (SIE) cells, we have isolated two subpopulations endowed with different phenotypic properties. Clone SIE-F consists of large, highly spread cells that have a relatively slow growth rate, form contact-inhibited monolayers, do not grow under anchorage-independent conditions, express elevated levels of thrombospondin-1 (TSP-1) and are not tumorigenic in vivo. In contrast, clone SIE-S2 consists of small, spindle-shaped cells that have a high proliferation rate, do not show contact-inhibition, grow under anchorage-independent conditions, express very low levels of TSP-1 and are tumorigenic in vivo. Both clones express the endothelial markers vascular endothelial-cadherin and vascular intercellular adhesion molecule-1, but do not express CD31 and E-selectin. In addition, SIE-S2 cells, but not SIE-F cells, express the α-smooth muscle actin isoform. SIE-S2 cells, but not SIE-F cells, are able to form branching tubes in fibrin gels. The SIE-F and SIE-S2 clones, which have properties of nontransformed and transformed cells, respectively, should provide useful tools to investigate physiological and pathological processes involving vascular endothelium.
ISC-STS development for power supply to improve reliability in communication system

STSpsilas SCR installed for reliability improvement of important loadpsilas power supply in industry field where an average of 2% fault occurs. In order to improve these problems attached mechanical switch is parallel with SCRpsilas both end points so that SCR can function during the 60~200 [mS] for the mechanical switch action is possible. Also, an ISC (ideal state conditioning interlock device) system is developed so that the two power supply paths may not be thrown in at the same time. Therefore it removes the overlap section perfectly, raising reliability. These methods have reduced the fault rate remarkably at SCR's fatigue degree that is in operating conversion action less than 0.89 times a year. Even in the case where the SCRpsilas fault occurred, power supply was not discontinued. It contributes to the promotion of reliability in the uninterruptible power supply device in communication system.
Should imaging be a component of rheumatoid arthritis remission criteria? A comparison between traditional and modified composite remission scores and imaging assessments

Objectives Patients can fulfil clinical criteria for remission, yet still have evidence of synovitis detectable clinically and by ultrasound, and this is associated with structural damage. Stricter remission criteria may more accurately reflect true remission (no synovitis). This hypothesis was examined by studying patients using more stringent thresholds for clinical remission and determining their levels of ultrasound synovitis. Methods Rheumatoid arthritis patients with a disease activity score in 28 joints (DAS28) ≤2.6 for at least 6 months were classified using standard and more stringent DAS28 and simplified disease activity index (SDAI) remission thresholds and the corresponding clinical and ultrasound imaging measures of synovitis recorded. Results 128 patients (all DAS28 <2.6, median DAS28 1.70) receiving either disease-modifying antirheumatic drugs alone (n=66) or with a tumour necrosis factor blocker (n=62) were recruited. Of the 640 imaged joints, 5% had moderate or severe power Doppler (PD) activity, 8% were clinically swollen and 1% tender. In patients fulfilling DAS28, American College of Rheumatology or SDAI remission criteria, moderate or severe PD activity was present in 21%, 15% and 19%, respectively. More stringent DAS28 and SDAI criteria reduced the mean number of swollen and tender joints (p<0.001) but not the percentage of patients with PD activity: 32 patients had a DAS28 <1.17 but eight (25%) had significant PD activity. Conclusion Using more stringent remission criteria resulted in reduced signs and symptoms of inflammation, but the percentage of joints with PD activity was not reduced, even in those without signs or symptoms. These data suggest that clinical criteria are sufficiently insensitive to detect low but clinically relevant levels of inflammation accurately.
QoS and Energy Aware Geographic Routing Protocol for WSN

— Due to the approved content nature, mostly collected of images and/or video streams with high throughput and delay restrictions, Quality of Service in the framework of WSN is a critical issue. In this paper, we propose a QoS and energy aware geographic routing protocol for WSN. To advance the efficiency of QoS routing in WSNs, we sketch the problem of efficient GOR for multiconstrained QoS provisioning in WSNs, which can be expressed as a multiobjective multiconstraint optimization problem. Based on the investigation and interpretations of different routing metrics in GOR, we then suggest an Efficient QoS-aware GOR (EQGOR) protocol for QoS provisioning in WSNs. EQGOR selects and orders the advancing candidate set in well-organizedmethod, which is suitable for WSNs in respect of energy efficiency, latency, and time difficulty.
Face Recognition by Artificial Vision Systems: a Cognitive Perspective

Cognitive development refers to the ability of a system to gradually acquire knowledge through experiences during its existence. As a consequence, the learning strategy should be represented as an integrated, online process that aims to build a model of the "world" and a continuous update of this model. Considering as reference the Modal Model of Memory introduced by Atkinson and Schiffrin, we propose an online learning algorithm for cognitive systems design. The incremental part of the algorithm is responsible of updating existing information or creating new data categories and the decremental part, to efficiently evaluate the system's performance facing partial or total loss of data. The proposed algorithm has been applied to the face recognition problem. More generally, the current approach can be extended to large-scale classification problems, to limit the memory requirements for optimal data representation and storage.
Sentiment Analysis Reloaded - A Comparative Study on Sentiment Polarity Identification Combining Machine Learning and Subjectivity Features

This paper presents an empirical study on machine learning-based sentiment analysis. Though polarity classification has been extensively studied at different document-structure levels (e.g. document, sentence, words), little work has been done investigating feature selection methods and subjectivity resources. We systematically analyze four different English subjectivity resources for the task of sentiment polarity identification. While the results show that the size of dictionaries clearly correlate to polarity-based feature coverage, this property does not correlate to classification accuracy. Using polarity-based feature selection, considering a minimum amount of prior polarity features, in combination with SVM-based machine learning methods exhibits the best performance (acc = 84.1, f 1 = 83.9), in comparison to the classical approaches on polarity identification. Based on the findings of the English-based experimental setup, a new German subjectivity resource is proposed for the task of German-based sentiment analysis. The results of the experiments show, with f 1 = 85.9 its good adaptability to the new domain.
THE LIFETIME AND POWERS OF FR IIs IN GALAXY CLUSTERS

We have identified and studied a sample of 151 FR IIs found in brightest cluster galaxies (BCGs) in the MaxBCG cluster catalog with data from FIRST and NVSS. We have compared the radio luminosities and projected lengths of these FR IIs to the projected length distribution of a range of mock catalogs generated by an FR II model and estimate the FR II lifetime to be 1.9 × 108 yr. The uncertainty in the lifetime calculation is a factor of two, primarily due to uncertainties in the intracluster medium (ICM) density and the FR II axial ratio. We furthermore measure the jet power distribution of FR IIs in BCGs and find that it is well described by a log-normal distribution with a median power of 1.1 × 1037 W and a coefficient of variation of 2.2. These jet powers are nearly linearly related to the observed luminosities, and this relation is steeper than many other estimates, although it is dependent on the jet model. We investigate correlations between FR II and cluster properties and find that galaxy luminosity is correlated with jet power. This implies that jet power is also correlated with black hole mass, as the stellar luminosity of a BCG should be a good proxy for its spheroid mass and therefore the black hole mass. Jet power, however, is not correlated with cluster richness, nor is FR II lifetime strongly correlated with any cluster properties. We calculate the enthalpy of the lobes to examine the impact of the FR IIs on the ICM and find that heating due to adiabatic expansion is too small to offset radiative cooling by a factor of at least six. In contrast, the jet power is approximately an order of magnitude larger than required to counteract cooling. We conclude that if feedback from FR IIs offsets cooling of the ICM, then heating must be primarily due to another mechanism associated with FR II expansion.

Antimicrobial Activity of Antibiotic-treated Amniotic Membrane: An In Vitro Study

Purpose: To investigate if amniotic membrane incubated with antibiotics could inhibit bacterial growth in vitro. Methods: Amniotic membrane fragments were incubated with the antibiotics (netilmicin) solution; the washed and drained fragments were either tested after treatment or further incubated in antibiotic-free medium. The antibacterial activity of both amniotic membrane and elution media was carried out by the Agar diffusion method, with Staphylococcus epidermidis as indicator, measuring the inhibition zone after overnight incubation. Results: The amniotic membrane fragments soaked in antibiotics inhibited bacterial growth. Antibiotic uptake was dose-dependent and occurred rapidly. The drug was released from the membrane, and the antibacterial effect was present in the elution media at least 3 days after treatment. Conclusions: Our preliminary in vitro data show that amniotic membrane can absorb the antibiotic netilmicin and in the future may be used to deliver antibiotics, as reported for collagen shields and other medical prosthetic devices.
Neighbourhood socioeconomic status, maternal education and adverse birth outcomes among mothers living near highways

Background: Residential proximity to highways is a potential proxy for exposure to traffic-related pollution that has been linked to adverse birth outcomes. We evaluated whether proximity to highway interacts with individual and neighbourhood socioeconomic status (SES) to influence birth outcomes. Methods: The study population consisted of all live singleton births in Montréal, Canada, from 1997 to 2001 (n = 99 819). Proximity was defined as residing within 200 m of a highway. Neighbourhood SES was measured for census tracts as the proportion of families below the low-income threshold. Individual SES was represented by maternal education. Using multilevel logistic regression, the odds of preterm birth (PTB), low birthweight (LBW) and small-for-gestational-age (SGA) birth were calculated for mothers residing in proximity to highways, accounting for individual and neighbourhood SES. Effect modification between SES and proximity to highway was tested for each outcome. Results: In wealthy neighbourhoods, proximity to highway was associated with an elevated odds of PTB (OR 1.58, 95% CI 1.23 to 2.04), LBW (OR 1.81, 95% CI 1.36 to 2.41) and SGA birth (OR 1.32, 95% CI 1.05 to 1.66). For highly educated mothers, proximity to highway was associated with PTB (OR 1.25, 95% CI 1.07 to 1.46) and LBW (OR 1.24, 95% CI 1.03 to 1.49), but the association was borderline for SGA birth (OR 1.15, 95% CI 1.00 to 1.32). Proximity to highway was not associated with birth outcomes in other maternal and neighbourhood SES categories. Conclusion: Counterintuitively, high SES mothers may be more likely than low SES mothers to experience adverse births associated with residential proximity to highway.
Coordinate descent accelerations for signal recovery on scale-free graphs based on total variation minimization

We extend our previous work on learning smooth graph signals from a small number of noisy signal samples. Minimizing the signal's total variation amounts to a non-smooth convex optimization problem. We propose to solve this problem using a combination of Nesterov's smoothing technique and accelerated coordinate descent. The resulting algorithm converges substantially faster, specifically for graphs with vastly varying node degrees (e.g., scale-free graphs).

Contribution à la suppression du phénomène stick slip et à la construction d'un observateur de dimension infinie en forage pétrolier

Les differents types de vibrations des garnitures de forage jouent un role important dans le dysfonctionnement des operations de forage car celles-ci conduisent a la rupture prematuree des trains de tiges, par consequent, a la perte de l'outil au fond du trou et aussi a l'endommagement de la machine. En s'interessant au forage de type rotary, cette these etudie le phenomene des vibrations de torsion de point de vu, modelisation par une EDP (modele distribue) dont on etabli les conditions aux limites adequats. Une large partie de notre analyse dans ce memoire concerne la commande du phenomene de vibration de torsion conduisant a une vitesse de rotation controlee sur le bord. La modelisation du phenomene de torsion affectant le train de tiges lors d'un forage petrolier a ete representee par une equation aux derivees partielles (1D) d'ordre deux: type lineaire integrant le phenomene de frottement. Deux entrees apparaissent dans les conditions aux limites en termes de vitesse de rotation du train et de la reaction avec le sol. Il s'agit donc de designer la commande en vitesse qui assure la rotation adequate pour le forage et qui n'excite pas le phenomene du torsion en tenant en compte l'interaction de la formation avec le sol. La stabilite de la garniture de forage depend d'un systeme de boue du fluide qui doit injecte. Nous traitons une connexion entre le systeme de forage rotary et le systeme du fluide. Nous obtenons un systeme couple sous la forme EDP-EDO. Egalement, nous avons transforme le systeme couple a un systeme neutre avec retard. Nos achevons ce memoire par la construction d'une loi de controle pour l'observateur du systeme de forage rotary avec une seule mesure aux limites dans le haut de la colonne pour estimer les parametres de l'outil de forage qui sont accessibles a mesurer.
A Keystone Mutualism Drives Pattern in a Power Function

Data that can be described by a power function are ubiquitous in nature. Although there is consensus that such data frequently emerge generally from nonlinear complex systems, a variety of specific mechanisms may be responsible for creating the pattern in particular cases. Here, we report on the distribution of a scale insect (Coccus viridis) that is a common agricultural pest. Its distribution in an organic coffee farm in southern Mexico generally follows a power function, but there are subtle deviations from that function. We offer a biological explanation for both adherence to the power functions and associated deviations, along with supporting evidence.
When does ellipsis occur, and what is elided?

Title of Dissertation: WHEN DOES ELLIPSIS OCCUR, AND WHAT IS ELIDED? Dongwoo Park, Doctor of Philosophy, 2017 Dissertation directed by: Professor Howard Lasnik Department of Linguistics Professor Omer Preminger Department of Linguistics This dissertation is concerned with how elliptical sentences are generated. To be specific, I investigate when and in what module ellipsis occurs, and what is elided as a result of ellipsis. With regard to the first research question, I propose that XP ellipsis occurs as soon as all the featural requirements of the licensor of XP ellipsis are satisfied during the derivation, rather than in the other modules. An important consequence of this proposal is that the point of XP ellipsis can vary depending on the derivational point where all the featural requirements of the licensor are satisfied in narrow syntax. Concerning the second research question, I suggest that ellipsis is a syntactic operation that eliminates phonological feature matrices of lexical items inside the ellipsis site, preserving the formal feature matrices. Segmental content (i.e. phonological features) is inserted into the phonological feature matrices when lexical items are sent to PF after Spell-out. This insertion does not apply to lexical items whose phonological feature matrices are eliminated, since there is no appropriate venue which segmental content is inserted into. Thus, they are not pronounced. This implies that even though narrow syntax cannot look into the information of the segmental content inside the phonological feature matrices, it can make reference to the phonological feature matrices in lexical items. This proposal is supported by the fact that elements whose phonological feature matrices have been eliminated can take part in further formal operations that occur after ellipsis, since they still contain formal features. However, unlike the other lexical items, elided interrogative whphrases do not seem to participate in formal operation occurring after ellipsis. In order to resolve this puzzle, I suggest a prosodic requirement questions must obey, adopting and modifying Richards’ (2016) Contiguity Theory. Standard English copular phrase ellipsis is mainly used to develop the present theory of ellipsis. Cross-linguistic evidence from Indian Vernacular English, Belfast English, Korean, Farsi, British English, and Dutch data is also provided to argue that the present theory of ellipsis is not restricted to English.

Competitive Representation Based Classification Using Facial Noise Detection

Linear representation based face recognition is hotly studied in recent years. Competitive representation classification is a linear representation based method which uses the most competitive training samples to sparsely represent a probe. However, possible noises on a test face image can bias the representation results. In this paper we propose a facial noise detection method to remove noises in the test image during the competitive representation. We compare the proposed method with others on AR, Extended Yale B, ORL, FERET, and LFW databases and the experimental results show the good performance of our method. Keywords—face recognition; sparse representation; biometrics; noise detection
“Confronted with paperwork”: Information and documentation in peer support

Background Peer support has a unique philosophy of practice, which is reflected in the way information is handled. Aims To describe the way peer supporters use documentation in their work and explore tensions this generates. Methods Qualitative study based on two individual or group interviews with each of 37 peer supporters and peer-support managers in Aotearoa New Zealand. Results Peer supporters challenged disciplinary uses of documentation by either keeping minimal information about their interactions with peers, or keeping notes in a collaborative, empowering and transparent manner. This generated tensions with regard to the wider mental health system, particularly in relation to an emerging national database of mental health service use. Conclusions Funders and planners need to be aware of the reasons for some peer-support services' reluctance to participate in mental health information strategies. Peer-support documentation approaches might usefully be adopted across the mental health sector.
Design of ultra-wideband Magic-T using microstrip/slot coupler and phase shifter

A broadband Magic-T using 3-dB coupler and 90° phase shifter is proposed in this paper. Microstrip/Slot technology has been employed in the design. Compared with the conventional magic-T, it can operate over an ultra-wideband. Results of simulation and measurement show that the relative bandwidth is 105 % with the VSWR less than 1.85, and the insertion loss less than 1.6 dB. The phase ripple is ±12°. The isolation is greater than 13dB across 2.5-8GHz.
