Experimental study on the flexural behavior of large-scale rectangular concrete-filled steel tubular beams Estudo experimental sobre o comportamento à flexão

Resumo This paper presents a series of test results of large-scale rectangular concrete-filled steel tubular (CFST) beams to explore their performance under pure bending. Concrete-filling tests were initially carried out on two beam specimens of 12-m in length to investigate the feasibility of casting horizontally large-scale rectangular tubes. A total of six 6-m long specimens were subjected to flexural test afterward, including four CFST beams and two steel hollow section (SHS) beams for comparison. The test results showed that the rectangular CFST beams behaved in a relatively ductile manner. The concrete infilling enhanced the flexural behavior and performance of the steel tubes. Finally, the rigid-plastic theory showed suitable to predict the moment capacity of CFST compact beams.
Inferring Phylogenies with RAxML-VI-HPC

Randomized Axelerated Maximum Likelihood version VI for High Perfor- mance Computing (RAxML-VI-HPC) is an efficient program for phylogenetic analy- ses with thousands of taxa under the popular Maximum Likelihood (ML) criterion. The software demonstration will cover the basic features of RAxML-VI-HPC and will show how to deploy it on sequential and parallel computer architectures for real- world phylogenetic studies. To the best of the authors knowledge RAxML-VI-HPC has been used to infer trees on the two largest data matrices analyzed under ML to date: a 25,057-taxon alignment of protobacteria (1,463 bp) and a 2,182-taxon align- ment of mammals (51,089 bp). The program is available as open-source code at diwww.epfl. ch/˜stamatak (software frame).
Investigating storage solutions for large data - A comparison of well performing and scalable data storage solutions for real time extraction and batch insertion of data

There are several systems developed today to handle the problem of storing large amounts of data. But for each type of data and set of operations different systems differ in suitability. Burt AB stores a large dataset, enlarged in batches in a regular and controlled way, but never updated. Query times are critical and must have real-time performance. This thesis describes a systematic exploration and testing of possible solutions, with the goal of recommending one of these for Burt AB. Inherent properties of the dataset itself are investigated and a set of very different database management systems are combined with a set of database schemas in order to form a total of eleven potential solutions of interest. We show that the relational model suits the data well and that the maturity of MySQL gives us confidence when recommending it compared to the more recently developed systems. Furthermore, indexing using an inverted index is found to yield the best results. Sammanfattning Det finns ett stort antal system som utvecklats for att losa problemet med att hantera mycket data, men vilken losning som ar bast beror pa vilken typ av data man har. Burt AB hanterar en stor datamangd som fylls pa med mycket ny data pa ett regelbundet och kontrollerat satt, men aldrig uppdateras. Lasning av datan maste dock kunna ske i realtid. Denna uppsats beskriver en systematisk utforskning och testning av mojliga losningar, med malet att rekomendera en av dessa for Burt AB. Egenskaper hos datan sjalv undersoks, och en handfull valdigt olika databashanteringssystem ar kombinerade med olika datasscheman for att skapa totalt elva olika potentiella losningar. Vi visar att relationsmodeller passar datan val, och att mognadsnivan hos MySQL ger den ett overtag gentemot andra mer nyligen utvecklade system. Utover detta sa visar det sig att inverterade index ar den bast lampade losningen for bra resultat.
Disc-loss episode in the Be shell optical counterpart to the high-mass X-ray binary IGR J21343+4738

Context. Present X-ray missions are regularly discovering new X-ray and γ-ray sources. The identification of their counterparts at other wavelengths allows us to determine their nature. Aims. The main goal of this work is to determine the properties of the optical counterpart to the INTEGRAL source IGR J21343+4738, and to study its long-term optical variability. Although its nature as a Be/X-ray binary has been suggested, little is known about its physical parameters. Methods. We have been monitoring IGR J21343+4738 since 2009 in the optical band. We present BVRI optical photometric and spectroscopic observations covering the wavelength band 4000‐7500 A. The photometric data allowed us to derive the colour excess E(B − V) and estimate the distance. The blue-end spectra were used to determine the spectral type of the optical companion, while the spectra around the Hα line allowed us to study the long-term structural changes in the circumstellar disc. Results. We find that the optical counterpart to IGR J21343+4738 is a V = 14.1 B1IVe shell star located at a distance of ∼8.5 kpc. The Hα line changed from an absorption-dominated profile to an emission-dominated profile, and then back again into absorption. In addition, fast line profile asymmetries were observed once the disc developed. Although the Balmer lines are the most strongly affected by shell absorption, we find that shell characteristics are also observed in He I lines. Conclusions. The optical spectral variability of IGR J21343+4738 is attributed to the formation of an equatorial disc around the Be star and the development of an enhanced density perturbation that revolves inside the disc. We have witnessed the formation and dissipation of the circumstellar disc. The strong shell profile of the Hα and He I lines and the fact that no transition from the shell phase to a pure emission phase is observed imply that we are seeing the system near edge-on.
Modelling and Visualizing Perspectives in Internet Digital Libraries

This paper is concerned with the interpretation of scholarly documents. We begin by examining core tasks that face a scholar in interpreting a scholarly document, or a collection of documents. We then argue that current approaches to document description, and current technological infrastructures, particularly over the World Wide Web, provide very poor support for these interpretive tasks. We describe an approach to modelling the perspectives in which documents are embedded, based on researchersO claims about their own work, and those of others. We detail how such a model is being implemented in a Web environment, and the services it could provide to a scholarly community. These include the creation, visualization and interpretation of conceptual structures reflecting the relations between different research efforts, scholarly perspectives and debates.
Low cycle fatigue damage analysis using the boundary element method

This paper introduces the application of the boundary element method (BEM) to the analysis and quantification of low cycle fatigue damage analysis of engineering components. Boundary integral equations for cyclic plasticity are formulated using initial stress and strain approaches together with appropriate kinematic hardening rules. A number of accuracy measures have been introduced into the numerical treatment of the boundary integral equations to improve the accuracy and reliability of the BEM results. Equivalent strains are employed in conjunction with the Mason Coffin equations for the prediction of low cycle fatigue life. A number of case studies have been analysed, using the developed BEM, and the results from the case studies have been compared with those obtained using the finite element method. The case studies quite clearly demonstrate that the boundary element method can provide very accurate and reliable results for such a non-linear analysis.

The analysis of transcriptomic experiments with ordered covariates, such as dose-response data, has become a central topic in bioinformatics, in particular in omics studies. Consequently, multiple R packages on CRAN and Bioconductor are designed to analyse microarray data from various perspectives under the assumption of order restriction. We introduce the new R package IsoGene Graphical User Interface (IsoGeneGUI), an extension of the original IsoGene package that includes methods from most of available R packages designed for the analysis of order restricted microarray data, namely orQA, ORIClust, goric and ORCME. The methods included in the new IsoGeneGUI range from inference and estimation to model selection and clustering tools. The IsoGeneGUI is not only the most complete tool for the analysis of order restricted microarray experiments available in R but also it can be used to analyse other types of dose-response data. The package provides all the methods in a user friendly fashion, so analyses can be implemented by users with limited knowledge of R programming.
A Multi-Accelerator Architecture for Photon Mapping

Real-time rendering of photorealistic images has always been an important goal in Computer Graphics. The most computationally expensive part of this process is obtaining the effects of global illumination. Photon mapping is a well-known technique for calculation of realistic global illumination, and also shows characteristics which we believe make it favorable for dedicated hardware acceleration.Online arithmetic is a digit-serial form of arithmetic, where input vectors are processed from the most significant digit down to the least, and the result is also produced one digit at each step. Pipelined online arithmetic circuits are extremely regular while only requiring simple calculations between registers, which allows for high clock speeds and low power dissipation with a huge potential for parallel execution.Combining these two concepts, we design and evaluate MAPM (Multi-Accelerator for Photon Mapping), a multi-accelerator architecture that employs pipelined online arithmetic to accelerate the two most time consuming operations in photon mapping: the tree search and shader operation. On a VHDL implementation, we perform behavioral verification using ModelSim, examine hardware cost with Synopsys tools and evaluate throughput gain and scalability of the architecture using a custom built cycle-accurate simulator based on the Intel Pin tool.By employing two MAPMs set to a configuration of 16 Tree Search Modules, 16 Shader Operation Modules and 2 Shader Operation Accelerators per Shader Operation Module, we observed a throughput increase of 1384x over an optimized software setup, and an increase of 4.78x over a recent MPSoC implementation. This is achieved using an acceptable hardware cost of 28.8% of the bandwidth, 22.2% of the area, and 5.6% of the power consumption of the low-end Intel Celeron G1820T.The MAPM also shows a significant reduction in power dissipation. Compared to a conventional parallel circuit with equivalent functionality, the MAPM showed a synthesizable clock speed at about 3.5x, dynamic power consumption of 0.104x, and area cost of 1.799x.

Status of the Baikal-GVD experiment - 2017

Baikal-GVD is a kilometer scale neutrino telescope under construction in Lake Baikal, which will be formed by multimegaton subarrays – clusters of strings. First demonstration cluster “Dubna” has been deployed in 2015 and comprises 192 optical modules (OMs). In 2016 cluster “Dubna” was upgraded to baseline configuration which comprises 288 OMs arranged at eight strings. The second full scale GVD-cluster was deployed and put in operation in 2017 in Lake Baikal. We review a present activity towards the GVD implementation and discuss some selected results obtained with array “Dubna”.
Technical Evaluation of C3-MR and Cascade Cycle on Natural Gas Liquefaction Process

Several types of liquefaction technologies have been extensively utilized to convert raw natural gas into a liquid state known asLiquefied Natural Gas or LNG. Selecting a specific liquefaction technology – e.g. APCI C3-MR, Conoco Philips Basic Cascade Process, Shell DMR, or Linde Mixed Fluid Cascade Processvaries from one LNG plant to the next. This paper presents the simulation of C3-MR and Cascade pure refrigerant process – likely technology for Timor LNG – by using Aspen Hysys V7.3 on the basis of Peng-Robinson equation of state. Both processes were simulated based on data of natural gas temperature, pressure, composition and flow rate. These data were obtained from an LNG Plant – “Timor LNG” that is planned to be built in Timor-Leste. During the simulations the effects were analyzed by examining specific horse power, LNG production and revenue of LNG derived from both processes. The analysis of specific horse power on the liquefaction process for C3-MR and pure refrigerant shows that using pure refrigerant has lower specific horse power than C3-MR by 69%. However, LNG production capacity of simulated processes shows that C3-MR has higher production capacity per train of (2.86 MTPA/Train) than pure refrigerant cascade which is (2.64 MTPA/Train). Also the revenue of LNG for C3-MR process exceeded that of pure refrigerant cascade by 94%. In order to better understand the liquefaction process, this paper also discussed the thermodynamic analysis of liquefaction plant.
Apropiación, diálogo e hibridación: escenas de blues en Austin y Madrid

Esta tesis doctoral analiza la musica blues como fenomeno artistico, comunicativo y sociocultural mediante un estudio comparativo de las escenas de blues en Austin, Texas y en Madrid (Espana), dos capitales de referencia con una relacion diferenciada respecto a la tradicion original del genero. Conocida y promocionada como “la capital mundial de la musica en vivo”, Austin esta historica, geopolitica y socioculturalmente inserta en la tradicion del blues, mientras que Madrid, historicamente alejada, lleva decadas incorporandose a ella mediante una compleja practica musical, colectiva y cotidiana. A pesar de su reconocimiento desigual (tanto en sus respectivos estados como en la cultura global del blues), las dos escenas ocupan un lugar analogo en la esfera publica underground y son muy similares en estructura y organizacion. Comparten practicas sociales y musicales, textos, discursos, relatos, imaginarios y formas de expresion, y algunos de sus participantes han desarrollado vinculos colaborativos transatlanticos en torno al blues y la musica en vivo.
Mergers, Acquisitions and Technological Regimes: The European Experience over the Period 2002-2005

Comparisons by countries and by sectors of mergers and acquisitions have usually been performed in separate fields of research. A first group of studies, focusing on international comparisons, has explored the role of corporate governance systems, investor protection laws and other countries’ regulatory institutions as the main determinants of takeovers around the world. A second group of contributions has attributed a central role to variations in industry composition, documenting that, in each country, mergers occur in waves and within each wave clustering by industry is observed. This paper aims to integrate both perspectives and to make comparisons by countries and by sectors, thus exploring the role of various driving forces on takeover activities. It also intends to consider the specific influence that technological regimes and their innovation patterns may exert in reallocating assets and moving capital among sectors. This will be done by examining the European experience of the last few years (2002-2005). We found that even in countries where transfer of control is a frequent phenomenon, mergers are less frequent in those sectors where innovation is a cumulative process and where takeovers may be a threat to the continuity of accumulation of innovative capabilities.
Interacting with Wearable Computers: Techniques and Their Application in Wayfinding Using Digital Maps

Wearable computers are a special case of mobile computers. They are either embedded in clothing, or they may even be the clothing. They are very personal in nature, being always with the user, always on and always ready. The aim in developing wearable computers is to provide the user with instant and easy-touse access to digital information sources anytime, anywhere. Wearable computers are a potential platform for several location-aware software applications. One such application is a personal navigation assistant that is aware of the user’s current geographical location, and has access to a database that contains maps of the current surroundings. Equipped this way, the assistant can provide the user with easy to understand and real-time instructions on how to reach a specific destination, and assist in exploring the environment without getting lost. This dissertation addresses the issues that arise when personal navigation assistants for wearable computers are developed. The research comprises eight studies in the areas of human-map interaction, wearable computing, and human-computer interaction. Two research methods have been applied: in the constructive research part, a navigation application, including several interaction techniques suitable for wearable use, has been developed. In the empirical research part, the methods and techniques developed have been evaluated to assess their usability. As a result – in addition to the navigation application itself – a set of user interaction techniques and interface components that support the various tasks needed in wayfinding has been proposed. These include a finger-based interaction technique, an efficient list searching technique, and a novel pocket-based user interface metaphor. The results also include guidelines for designing the map behavior while navigating.
A 1.7 Gbps DLL‐Based Clock Data Recovery for a Serial Display Interface in 0.35‐μm CMOS

This paper presents a delay‐locked‐loop–based clock and data recovery (CDR) circuit design with a nB(n+2)B data formatting scheme for a high‐speed serial display interface. The nB(n+2)B data is formatted by inserting a ‘01’ clock information pattern in every piece of N‐bit data. The proposed CDR recovers clock and data in 1:10 demultiplexed form without an external reference clock. To validate the feasibility of the scheme, a 1.7‐Gbps CDR based on the proposed scheme is designed, simulated, and fabricated. Input data patterns were formatted as 10B12B for a high‐performance display interface. The proposed CDR consumes approximately 8 mA under a 3.3‐V power supply using a 0.35‐μm CMOS process and the measured peak‐to‐peak jitter of the recovered clock is 44 ps.
Growth, Secular Stagnation and Wealth Preference

In 1960s-1980s Japan enjoyed high economic growth. In the early 1990s, however, the growth rate drastically declined and thereafter Japan has been suffering secular stagnation. This paper proposes a dynamic macroeconomic model that can consistently explain such a drastic change in economic performance. Wealth preference plays an important role. In the early stage consumption grows at the same pace as productivity increases. Once consumption reaches a certain level, however, it deviates from the full-employment level and aggregate demand deficiency appears. After that the economic growth rate asymptotically approaches zero even if productivity keeps on increasing, and secular stagnation arises.
Labouring Together, Listening Together? Improving the effectiveness of short-term mission in Moldova by understanding church leaders' experiences of working with foreign short-term missionaries

As a Christian missionary working in Moldova since 2007, this author has hosted many shortterm missions teams. Consulting the missiological literature, it became clear that short-term mission, like Moldova itself, has been neglected by missiologists; and that, just as Moldova is a young country barely out of its teenage years, this is a young discipline also at a significant juncture. The vast majority of literature concerning short-term mission has been written from the perspective of senders/goers whilst the opinions of recipient cultures and host churches have seldom been heard or sought.
Display Format Effects on Precision Tracking Performance, Describing Functions, and Remnant.

Abstract : As part of a program to develop a comprehensive theory of manual control displays, six display formats were used by three instrument-rated pilots to regulate against random disturbances with a controlled element of Y sub c = K/s(s + 2) (which requires mild lead equalization), under both foveal and 10 deg parafoveal viewing conditions. The six display formats were: CRT Line, CRT Thermometer Bar, 14-Bar Quantized on a CRT, a Rotary Dial and Pointer (meter movement), and two variations of a Moving Scale Tape-Drive (C-141 VSI). All were scaled to equivalent movement and apparent brightness. Measures included overall performance, describing functions, error remnant power spectra, critical instability scores, and subjective display ratings. Other controlled elements and parafoveal angles were partially investigated. The results show that the main effect of display format is on the loop closure properties. (Author)
Assessing Information Trustability in a Secure Web Services Environment

Abstract : Decisions are made based on available information. A decision support system endeavors to provide information that is timely, accurate, and trustable. Information gathered from secure web service transactions has attributes that can be used to assess a level of trustability. The trust assessments enable a decision maker to determine a basis for confidence in the information presented from the web service. Existing trust assessment models do not provide a way to determine from a particular trust assessment what information attributes contributed to its computation. The present work creates trust values that retain and denote meaning, allowing a decision maker to see specifically what factors influenced the information trust assessment. Also central to this work is interpretation of the trust assessments. The interpretation model allows users to specify the amount of allowable tolerance for reduced trustability in the decision being made. This "dial-a-trust" allows the interpretation to be scaled relative to the impact of the decision. The trust assessment values, along with their interpretations, allow both human and machine-based decision makers to determine whether information is trustable enough for the needs of the decision being made.
A Framework For Learning Scene Independent Edge Detection

A Framework For Learning Scene Independent Edge Detection Aaron J. Wilbee Supervising Professor: Dr. Ferat Sahin In this work, a framework for a system which will intelligently assign an edge detection filter to an image based on features taken from the image is introduced. The framework has four parts: the learning stage, image feature extraction, training filter creation, and filter selection training. Two prototypes systems of this framework are given. The learning stage for these systems is the Berkeley Segmentation Database coupled with the Baddelay Delta Metric. Feature extraction is performed using a GIST methodology which extracts color, intensity, and orientation information. The set of image features are used as the input to a single hidden layer feed forward neural network trained using back propagation. The system trains against a set of linear cellular automata filters which are determined to best solve the edge image according to the Baddelay Delta Metric. One system uses cellular automata augmented with a fuzzy rule. The systems are trained and tested against the images from the Berkeley Segmentation Database. The results from the testing indicate that systems built on this framework can perform better than standard methods of edge detection on average across many types of images.
