Perceptual Rules for Building Enhancements in 3D Virtual Worlds

Abstract While the generation of geometric 3D virtual models has become feasible to a great extent, the enrichment of the resulting urban building models with semantics remains an open research question in the field of geoinformation and geovisualisation. This additional information is not only valuable for applications like Building Information Modeling (BIM) but also offers possibilities to enhance the visual insight for humans when interacting with that kind of data. Depending on the application, presenting users the highest level of detail of building models is often neither the most informative nor feasible way. For example when using mobile apps, resources and display sizes are quite limited. A concrete use case is the imparting of building use types in urban scenes to users. Within our preliminary work, user studies helped to identify important features for the human ability to associate a building with its correct usage type. In this work we now embed this knowledge into building category-specific grammars to automatically modify the geometry of a building to align its visual appearance to its underlying use type. If the building category for a model is not known beforehand, we investigate its feature space and try to derive its use type from there. Within the context of this work, we developed a Virtual Reality (VR) framework that gives the user the possibility to switch between different building representation types while moving in the VR world, thus enabling us in the future to evaluate the potential and effect of the grammar-enhanced building model in an immersive environment.
Fatigue-life and leak-before-break assessments of CR-MO steel pressure vessels with high-pressure gaseous hydrogen

Pressure cycle tests were performed on two types of Cr-Mo steel pressure vessels with inner diameters of 306 mm and 210 mm and notches machined on their inside under hydrogen-gas pressures, varied between 0.6 and 45 MPa at room temperature. One of the Cr-Mo steels had a fine microstructure with tensile strength of 828 MPa, while the other had a coarse microstructure with tensile strength of 947 MPa. Fatigue-crack growth (FCG) and fracture-toughness tests of the Cr-Mo steels were also carried out in gaseous hydrogen. The Cr-Mo steels showed accelerated FCG rates in gaseous hydrogen compared to ambient air with an upper bound corresponding to an approximately 30-times higher FCG rate. Furthermore, in gaseous hydrogen, the fracture toughness of the Cr-Mo steel with coarse microstructure was significantly smaller than that of the steel with fine microstructure. Four pressure vessels were tested; then, all of the pressure vessels failed by leak-before-break (LBB). Based on the fracture-mechanics approach, the LBB failure of one pressure vessel could not be estimated by using the fracture toughness in gaseous hydrogen. The fatigue lives could be estimated by using the upper bound of the accelerated FCG rates in gaseous hydrogen.Copyright © 2014 by ASME
Acceptability and Effect of a Community-Based Alcohol Education Program in Rural Sri Lanka

Aims: To assess the effectiveness and acceptability of a brief community-based educational program on changing the drinking pattern of alcohol in a rural community. Methods: A longitudinal cohort study was carried out in two rural villages in Sri Lanka. One randomly selected village received a community education program that utilized street dramas, poster campaigns, leaflets and individual and group discussions. The control village had no intervention during this period. The Alcohol Use Disorder Identification Test (AUDIT) was used to measure the drinking pattern before and at 6 and 24 months after the intervention in males over 18 years of age in both villages. The recall and the impact of various components of the intervention were assessed at 24 months post-intervention. Results: The intervention was associated with the development of an active community action group in the village and a significant reduction in illicit alcohol outlets. The drama component of the intervention had the highest level of recall and preference. Comparing the control and intervention villages, there were no significant difference between baseline drinking patterns and the AUDIT. There was a significant reduction in the AUDIT scores in the intervention village compared with the control at 6 and 24 months (P < 0.0001). Conclusions: A community-based education program had high acceptance and produces a reduction in alcohol use that was sustained for 2 years.
Polyamide 6/Polypropylene/Organoclay Nanocomposites: Influence of Organoclay and Compatibiliser on the Morhological and Tensile Properties

Nanokomposit poliamida 6/polipropilena (PA6/PP) telah disediakan dengan menggunakan pengekstrud skru kembar dan mesin pengacuanan suntikan. Kesan penambahan organotanah liat daripada 2% mengikut berat hingga 10% mengikut berat ke atas sifat-sifat tensil bagi komposit PA6/PP telah dikaji. Daripada kajian yang telah dijalankan, didapati komposit yang mengandungi organo-tanah liat sebanyak 4% mengikut berat telah menunjukkan penambahan yang optimum bagi komposit PA6/PP. 5% mengikut berat MAH-g-PP telah ditambahkan sebagai agen penyerasian dalam nanokomposit PA6/PP yang mengandungi 4% mengikut berat organo-tanah liat. Permukaan perekahan selepas ujian tensil bagi nanokomposit PA6/PP telah dikaji dengan menggunakan mikroskop penskanan elektron (SEM). Penambahan MAH-g-PP telah meningkatkan sifat-sifat mekanikal bagi nanokomposit PA6/PP/organo-tanah liat. Morfologi yang kasar dan rapuh telah diperhatikan bagi nanokomposit PA6/PP/organo-tanah liat tanpa MAH-g-PP. Manakala, bagi nanokomposit PA6/PP/organo-tanah liat yang mengandungi MAH-g-PP, morfologi yang menunjukkan dominasi fibril telah diperhatikan. Ini menunjukkan bahawa MAH-g-PP berkebolehan untuk meningkatkan pelekatan antara muka dan interaksi antara PA6, PP dengan organo-tanah liat. Kata kunci: Nanokomposit poliamida 6/polipropilena (PA6/PP); Organo-tanah liat; MAH-g-PP; sifat-sifat tensil; morfologi Polyamide 6/polypropylene (PA6/PP) nanocomposite was prepared by twin screw extruder and injection molding machine. The effect of organoclay loading from 2 wt% up to 10 wt% on the tensile properties was studied. 4 wt% organoclay has been observed to be the optimum loading for PA6/PP blends. Maleic anhydride grafted polypropylene (MAH-g-PP) at 5 wt% was used as a compatibiliser for 4 wt% organoclay filled PA6/PP nanocomposites. Failure mechanisms of PA6/PP/organoclay nanocomposites, assessed by fracture surface studies in a scanning electron microscopy (SEM) are discussed. The incorporation of MAH-g-PP increased mechanical properties of PA6/PP/organoclay nanocomposites. A coarse and brittle morphology was observed for uncompatibilised PA6/PP nanocomposites. On the contrary, MAH-g-PP compatibilised PA6/PP nanocomposites showed a more fibrilous dominant morphology, which indicates that MAH-g-PP is capable of promoting a better adhesion and interaction between PA6, PP and organoclay. Key words: POlymide 6/polypropylene (PA6/PP) nanocomposit; organoclay; maleic anhydride grafted polypropylene (MAH-g-PP); tensile properties; morphology
Maternal Nutrient Restriction During Late Gestation and Early Postnatal Growth in Sheep Differentially Reset the Control of Energy Metabolism in the Gastric Mucosa

Fetal growth restriction followed by accelerated postnatal growth contributes to impaired metabolic function in adulthood. The extent to which these outcomes may be mediated centrally within the hypothalamus, as opposed to in the periphery within the digestive tract, remains unknown. In a sheep model, we achieved intrauterine growth restriction experimentally by maternal nutrient restriction (R) that involved a 40% reduction in food intake through late gestation. R offspring were then either reared singly to accelerate postnatal growth (RA) or as twins and compared with controls also reared singly. From weaning, all offspring were maintained indoors until adulthood. A reduced litter size accelerated postnatal growth for only the first month of lactation. Independently from postnatal weight gain and later fat mass, R animals developed insulin resistance as adults. However, restricted accelerated offspring compared with both the control accelerated and restricted restricted offspring ate less and had higher fasting plasma leptin as adults, an adaptation which was accompanied by changes in energy sensing and cell proliferation within the abomasum. Additionally, although fetal restriction down-regulated gene expression of mammalian target of rapamycin and carnitine palmitoyltransferase 1-dependent pathways in the abomasum, RA offspring compensated for this by exhibiting greater activity of AMP-activated kinase-dependent pathways. This study demonstrates a role for perinatal nutrition in the peripheral control of food intake and in energy sensing in the gastric mucosal and emphasizes the importance of diet in early life in regulating energy metabolism during adulthood.
Measurements of mechanical properties of microfabricated thin films

Mechanical properties of titanium thin films of 0.5 /spl mu/m thickness, microfabricated by magnetron sputtering, were measured by using a novel tensile machine. These thin films are difficult to handle because they are markedly fragile, so the thin film specimens were fabricated by using semiconductor manufacturing technology in silicon frames to protect them. The test section of these specimens was 300 /spl mu/m in width and 1.4 mm in length. By gripping the thin film specimen with a new device using a micrometer, it could be mounted on the tensile machine easily. The stress-strain diagrams of thin films were measured continuously in the atmosphere at room temperature. Tensile tests were conducted on specimens of 1.0 to 1.4 mm gauge length in order to examine the effect of gauge length on the measurements of mechanical properties. Measurements of Young's modulus, tensile strength and breaking elongation were independent of gauge length for our range of measurements. The experimental results indicated that the titanium thin films had a smaller breaking elongation although they had a larger tensile strength than bulk pure titanium.
A review of the cut-off points for the diagnosis of vitamin B12 deficiency in the general population

Abstract Vitamin B12 deficit is one of the most common vitamin deficiencies. However, there is no consensus on the cut-off points for vitamin B12 and its co-markers, such as folate, holotranscobalamin, methylmalonic acid and homocysteine. In order to establish the state of the art about cut-off points used to determine vitamin B12 deficiency in the last decades, the database MEDLINE was used for searching studies published in adults between December 1992 and May 2014 (69 articles), using search terms like ‘vitamin B12’, ‘cobalamin’, ‘cut-off’, ‘deficiency’ alone or in combinations. Broad ranges of cut-off points for vitamin B12 and its biomarkers were identified: vitamin B12 ranged between 100 pmol/L and 350 pmol/L, holotranscobalamin 20–50 pmol/L, methylmalonic acid 0.210–0.470 μmol/L, homocysteine 10–21.6 μmol/L, serum folate 3.7–15.9 nmol/L and red blood cell 124–397 nmol/L. For the majority of studies, the potential influence of age, analytical methods, gender and fortified food consumption was not taken in account when choosing cut-off values. This could explain the discrepancies between studies on vitamin B12 and folate deficiency prevalences. We conclude that there is inconsistency in the literature regarding vitamin B12 cut-offs. It would be necessary to establish different reference cut-offs according to age, considering the analytical methods used.
Multifrequency testability analysis for analog circuits

Testability analysis in analog circuits is an important task and a desirable approach for producing testable complex systems. In past years, most of the testability evaluation methods presented were based on measures of the degree of solvability of the fault diagnosis equations. In this paper, we study the testability of analog circuits in the frequency domain by introducing the analog fault observability concept. The proposed algorithm indicates the set of adequate test frequencies and test nodes to increase fault observability. We analyze the case of single fault and of double and multiple faults. Concepts such as fault masking, fault dominance, fault equivalence and non observable fault in analog circuits are defined and then used to evaluate testability. Finally, some experimental results are provided. <<ETX>>
Integrated Engineering Project Management Approach for Typical Small to Medium Manufacturing Companies

The aim of this paper is to identify the problem extents and successfully applying project management in SMEs with a focus on manufacturing industries. The organization of the study was mainly divided into the activity of literature study and the investigation through a survey conduct aimed to measure the awareness and implementation of project management at the selected SMEs in Malaysia. The questionnaire was designed with a section (Section A) involving project management in general and another section (Section B) involving the implementation of it. It was found that the level of awareness and implementation of project management especially in the selected small and medium manufacturing companies in Malaysia was quite satisfying. Most of the manufacturing companies were implementing project management, but the level was depending on the organization in the company itself.
On the approaches for efficient mobility management in SDNized wireless networks

In this paper, we study the scalability issues of SDNized wireless networks, specifically those relevant to mobility management. We study the improvements in handover delays: i) when a proposed proactive mobility management algorithm is implemented, ii) when the controller delegates partial control of mobility management to the forwarding entities. For the implementation of the proposed approaches on the OpenFlow network, the paper also suggests potential extensions to OpenFlow protocol. The contributed approaches are validated on a full scale demonstrator and results show that proactive outperforms reactive and the delegated control approach performs better than proactive for smaller topology sizes. Furthermore a proposal for LTE-X2 specific control delegation is discussed as use-case.
Keyword search: Quite exploratory actually

This short position paper describes some evidence found that counters the argument that there are better ways to support exploratory search than keyword search. Instead, this paper suggests that keyword search actually provides people with the freedom to search in relation to their own current state of understanding, rather than in the terms controlled by a search system. The challenge for future exploratory search systems, therefore, may be to maintain and enhance such freedoms.

Frequency of Functional Bowel Disorders among Healthy Volunteers in Mexico City

Background: The frequency of functional bowel disorders (FBD) in Mexico using the Rome II criteria is unknown. Methods: The Rome II Modular Questionnaire (RII-MQ) was translated into Spanish in coordination with the Rome Committee and their Latin American program. Volunteers were recruited by advertisement in Mexico City, and administered the RII-MQ. Results:The study population consisted of 324 healthy volunteers, with a mean age of 35.7; 66% were female. The most prevalent disorders were heartburn 35%, irritable bowel syndrome (IBS) 35%, functional bloating 21%, proctalgia fugax 21%, and functional constipation 19%. Based on gender, IBS-C was 4 times more frequent in females than males (19 vs. 4.6%) and functional bloating 3 times more frequent (10 vs. 3.7%). Differences according to occupation included a higher prevalence of ulcer-like dyspepsia (p = 0.04), IBS-C (p = 0.018) and proctalgia fugax (p = 0.034) among students. Conclusions: This is the first study to use RII-MQ to determine the prevalence of FBD in urban Mexico. The prevalence of IBS was significant and is related to a number of factors, including the stress of living in an overpopulated city. Selection bias is likely operative. A community-based study is warranted.
Identifying influential members of parliament using topological features in a co-votation network

Este trabalho propoe investigar se e possivel identificar parlamentares influentes usando apenas informacoes de resultados das votacoes. Dados oriundos das sessoes de votacao da plenaria da Câmara dos Deputados do Brasil durante o ano de 2015 foram usados para criar uma rede de co-votacao. Nessa rede, vertices representam parlamentares e arestas ponderadas representam a semelhanca entre parlamentares quanto ao seu comportamento de voto. Uma lista de deputados influentes elaborada por um grupo de pesquisa em ciencia politica foi utilizada como referencia. Inicialmente, explorou-se ranquear os deputados conforme diferentes conceitos de centralidade de rede. Em seguida, essas diferentes propriedades topologicas foram utilizadas de maneira conjunta como atributos para alimentar algoritmos de classificacao. Os resultados indicaram que, segundo a metrica da precisao media observada ao longo da curva de precisao-recuperacao, esse metodo desempenhou quase 3 vezes melhor que o esperado caso se montasse uma lista de parlamentes influentes de maneira aleatoria. Isso sugere que os resultados de votacoes parlamentares codificam informacoes relativas ao grau de influencia dos congressistas.
Determinants of Virological Response to Antiretroviral Therapy: Socio-Economic Status Still Plays a Role in the Era of cART. Results from the ANRS-VESPA 2 Study, France

Background Disparities in combined antiretroviral therapy (cART) outcomes have been consistently reported among people living with HIV (PLWHIV). The present study aims at investigating the mechanisms underlying those disparities among PLWHIV in France. Methods We used data from the Vespa2 survey, a large national cross-sectional survey, representative of HIV-infected people followed at hospitals in 2011. Among participants diagnosed ≥1996, HIV treatment-naive at the time of cART initiation and on cART for at least 12 months, the frequency of sustained virological suppression (SVS; undetectable viral load [<50 copies/ml] for at least 6 months) at the time of the survey, was assessed and its social determinants were measured through logistic regression, accounting for clinical and biological determinants of response to cART. Results Among 1,246 participants, 77.7% had achieved SVS. SVS was less frequent among those unemployed (0.6 [range 0.3-1.0]) and those with the lowest level of education (0.4 [range 0.2-0.9]). The late presenters, diagnosed at a CD4+ T-cell count <200/mm3 (0.5 [range 0.3-0.9]) and the late starters, diagnosed at a CD4+ T-cell count >200 but initiating cART at CD4+ T-cell count <200 (0.3 [range 0.1-0.8]) were less likely than the ideal starters (≥350 CD4+ T-cells/mm3 at cART initiation) to achieve SVS, as were those who reported suboptimal adherence versus those reporting optimal adherence (0.4 [range 0.2-0.7]). In bivariate analyses, material deprivation, discrimination and a weak social network were also associated with a poorer treatment response. Conclusions Structural social factors remain strong determinants of treatment response and should be addressed in a broad approach of care, but wider political issues should also be investigated.
POKer: a Partial Order Kernel for Comparing Strings with Alternative Substrings

We introduce a Partial Order Kernel (POKer) on the weighted sum of local alignment scores that can be used for comparison and clas-siﬁcation of strings containing alternative substrings of variable length. POKer is deﬁned over the product of two directed acyclic graphs, each representing a string with alternative substrings, and is computed eﬃciently using dynamic programming. We evaluate the performance of POKer with Support Vector Machines on a dataset of strings generated by detecting overlapping motifs in a set of simulated DNA sequences. Compared to a generalization of a state-of-the-art string kernel, POKer achieves a higher classiﬁcation accuracy.
Activity‐dependent control of NMDA receptor subunit composition at hippocampal mossy fibre synapses

CA3 pyramidal cells display input‐specific differences in the subunit composition of synaptic NMDA receptors (NMDARs). Although at low density, GluN2B contributes significantly to NMDAR‐mediated EPSCs at mossy fibre synapses. Long‐term potentiation (LTP) of NMDARs triggers a modification in the subunit composition of synaptic NMDARs by insertion of GluN2B. GluN2B subunits are essential for the expression of LTP of NMDARs at mossy fibre synapses.
A Compressed Sensing Approach to Block-Iterative Equalizers

The universality of underdetermined systems has nurtured a variety of novel compressed sensing (CS) algorithms that ingeniously exploit data sparsity. Whereas well-studied greedy and iterative threshold-based CS recursions take the form of an adaptive filter followed by a proximal operator, this is no different in spirit from the role of block iterative equalizers, where structure is roughly exploited by the signal constellation slicer. By capitalizing on the intrinsic sparsity of signal modulations, we approach the concept of interblock interference (IBI) more proficiently in light of CS concepts, where the optimal feedback of detected symbols is devised adaptively. This should be contrasted with standard forms of IBI estimation/cancellation commonly seen in block DFEs, where detection is restricted to a contiguous set of entries within the transmitted vector. A significant consequence of the latter is that, while block transceivers commonly employ some form of redundancy that accounts for IBI, a CS algorithm applied to the same transmitted vector may require no redundancy whatsoever, and is capable of retrieving both target symbol and IBI altogether. The CS-based iterative DFE acts as a more efficient re-estimation procedure, proposed under recursive-least-squares based adaptations. Besides maximizing system throughput, the new algorithms exhibit significantly higher performance when compared to existing methods that focus solely on minimized redundancy. Simulations in several scenarios illustrate the merits of the unified approaches.
