Load balancing in heterogeneous systems for computational fluid dynamics applications

In this thesis, a static load balancing model for CFD (Computational Fluid Dynamics) solvers is proposed. The proposed model is implemented and its performance is analyzed on EXN-Aero CFD Solver, a CFD solver owned by UNB. For some meshes and arrangement of resources, the proposed load balancing model is 70 percents faster than the previous load balancing model. Some of the features of the proposed model are generalizable to other applications.
Exploring the X-ray sky with the XMM-Newton bright serendipitous survey

We present here "The XMM-Newton Bright Serendipitous Survey", composed of two flux-limited samples: the XMM-Newton Bright Source Sample (BSS, hereafter) and the XMM-Newton "Hard" Bright Source Sample (HBSS, hereafter) having a flux limit of f(x) similar or equal to 7 x 10(-14) erg cm(-2) s(-1) in the 0.5-4.5 keV and 4.5-7.5 keV energy band, respectively. After discussing the main goals of this project and the survey strategy, we present the basic data on a complete sample of 400 X-ray sources (389 of them belong to the BSS, 67 to the HBSS with 56 X-ray sources in common) derived from the analysis of 237 suitable XMM-Newton fields (211 for the HBSS). At the flux limit of the survey we cover a survey area of 28.10 (25.17 for the HBSS) sq. deg. The extragalactic number-flux relationships (in the 0.5-4.5 keV and in the 4.5-7.5 keV energy bands) are in good agreement with previous and new results making us confident about the correctness of data selection and analysis. Up to now similar to71% (similar to90%) of the sources have been spectroscopically identified making the BSS (HBSS) the sample with the highest number of identified XMM-Newton sources published so far. At the X-ray flux limits of the sources studied here we found that: a) the optical counterpart in the majority (similar to90%) of cases has a magnitude brighter than the POSS II limit (R similar to 21(mag)); b) the majority of the objects identified so far are broad line AGN both in the BSS and in the HBSS. No obvious trend of the source spectra ( as deduced from the Hardness Ratios analysis) as a function of the count rate is measured and the average spectra of the "extragalactic" population corresponds to a (0.5-4.5 keV) energy spectral index of similar to0.8 (similar to0.64) for the BSS ( HBSS) sample. Based on the hardness ratios we infer that about 13% (40%) of the sources in the BSS ( HBSS) sample are described by an energy spectral index flatter than that of the cosmic X-ray background. Based on previous X-ray spectral results on a small subsample of objects we speculate that all these sources are indeed absorbed AGN with the N-H ranging from a few times 10(21) up to few times 10(23) cm(-2). We do not find strong evidence that the 4.5-7.5 keV survey is sampling a completely different source population if compared with the 0.5-4.5 keV survey; rather we find that, as expected from the CXB synthesis models, the hard survey is simply picking up a larger fraction of absorbed AGN. At the flux limit of the HBSS sample we measure surface densities of optically type 1 and type 2 AGN of 1.63 +/- 0.25 deg(-2) and 0.83 +/- 0.18 deg(-2), respectively; optically type 2 AGN represent 34 +/- 9% of the total AGN population. Finally, we have found a clear separation, in the hardness ratio diagram and in the (hardness ratio) vs. (X-ray to optical flux ratio) diagram, between Galactic "coronal emitting" stars and extragalactic sources. The information and "calibration" reported in this paper will make the existing and incoming XMM-Newton catalogs a unique resource for astrophysical studies.
Sales, Marketing, and Research-and-Development Cooperation across New Product Development Stages: Implications for Success

Prior research has identified the integration of marketing with research and development (R&D) as a key success factor for new product development (NPD). However, prior work has not distinguished the sales and marketing functions, even though they are distinctive departments within an organization. Therefore, the authors extend prior research and examine the effect of cross-functional cooperation among sales, marketing, and R&D on NPD performance across multiple stages of the NPD process. The authors use multiple-informant data from 424 sales, marketing, and R&D managers as well as project leaders of 106 NPD projects to test several hypotheses. The results show that the cooperation between sales and R&D and between sales and marketing has a significant, positive effect on overall NPD project performance beyond marketing–R&D cooperation. The authors also find that the effect of cross-functional cooperation among sales, marketing, and R&D on overall NPD project performance varies across stages of the NPD process. More specifically, the authors find that sales–R&D cooperation in the concept and product development stages is critical for greater new product success. Sales–marketing cooperation is important in the concept development stage but has surprisingly less impact in the implementation stage.
Carbon Footprint Assessment of a Residential Development Project

Buildings account for roughly one third of all green house gas emissions globally. Identifying the sources of these emissions and understanding their relations to the construction phase is essential in climate change mitigation. This study evaluates the carbon emissions caused by a residential construction project in Finland. The research method is modified tiered hybrid life cycle assessment. The study shows that the carbon emissions of a 220 homes development project are around 60 000 tons of which 90 percent initiates from actual buildings and ten percent from the supporting infrastructure. The sources of the carbon emissions are divided into numerous categories without any single dominant category. Thus, reducing the emissions requires a holistic management approach, as there are no single dominant materials in terms of carbon emissions. Also, the costs were found to poorly correlate with the carbon emissions, which implies that the traditional cost management strategy used in project management cannot directly deal with carbon management challenge. In addition, the results indicate that because of the rapid and high carbon spike of construction, the construction phase emissions are much more significant regarding the climate change than their share of the buildings' life cycle emissions would suggest. The study also shows that a generic LCA data model can be used to roughly estimate the emissions of a development project, but that a more detailed project specific data is needed for more accurate results. The difference between a generic and a project specific model were calculated to be roughly 20 percent. The results of the study may be applied to the evaluations of similar construction projects. The research method may also be used in future research as well as in further development of hybrid LCA methods.

NUMERICAL COMPUTATION OF FRACTIONAL PARTIAL DIFFERENTIAL EQUATIONS ARISING IN PHYSICS

In this article, we aim to propose a reliable numerical algorithm based on homotopy analysis transform method for solving various kinds of linear and nonlinear time-fractional partial differential equations arising in physics. The method is exemplified by linear and nonlinear time- fractional heat-like, invicid Burgers and fifth orders KdV equations arising in the study of thermodynamics, fluid mechanics and quantum mechanics respectively. We investigate the influence of the convergence- control parameter that provides us, a simple way to guarantee the convergence of series solution of linear and nonlinear problems. The proposed method may give better approximations which are uniformly valid for either small and large parameters or variables with highly accurate numerical solutions.
Twenty-One Century : The Informational Age

In nowadays’ informational society, both the rapid pace development of technology and Internet’s heavy influence on everyday’s life brought along new characteristics to the 21 century consumer. Accordingly, in this little e-s dominated world, it comes as no surprise that the booming business on the new virtual market, the Internet, triggered the appearance of a new consumer, the online consumer, by far more informed, open to progress and selective. Along with the shifts of the traditional consumer’ traits, this aim of this article is to emphasize, on a theoretical basis, the rising importance of the online consumer in the 21 century, and point out its main hallmarks and consumer behavior habits. With Generation Y, not only thriving in the digital era but also prevailing as the most active online shopper, the profile of the 21 century consumer is defined by a clearly new and enhanced perspective.
Are stock returns a leading indicator for real macroeconomic developments

I examine whether or not returns on stock markets are a leading indicator for real macroeconomic developments in Austria, Japan and the USA. Further I deal with the concept of stock market efficiency, the question whether or not information from real and financial sectors of the economy is consistently priced on stock markets. This would not be the case if past macroeconomic developments could be used to improve forecasts of subsequent stock returns. Time series models are used to investigate the respective long-run relations between stock prices and other macroeconomic variables as well as short-term dynamics. I conclude that none of the markets under study is efficient in the above-mentioned strict sense. Only U.S. stock returns lead private consumption and, rather weakly, retail sales growth.
An Analysis of Doctoral Dissertations Based on the Sex of Supervisors: A Case of Sociology Departments in Turkey

This study examines doctoral dissertations based on sex of supervisors year periods and universities in which have a sociology PhD program in Turkey and also it determines whether there are any significant differences according to those variables. Currently, Turkey has 169 universities that 63 of those have been admitting students for undergraduate program of sociology departments. In addition, 25 universities have doctoral program at sociology. However, doctoral dissertations have been conducted only in 14 universities among them. Totally 513 doctoral dissertations were found which were conducted between 1950 and 2012. In this study only 493 doctoral dissertations, out of 513, were analyzed. The qualitative and quantitative context analyze has been applied from the socio-historical critique point of view by using MAXQDA. Consequently, this study indicates that there is gender-related differentiation of doctoral dissertations' supervisors based on years and universities that doctoral dissertations were conducted in departments of sociology.
Unlimited Release Printed September 2009 Intelligent Front ‐ end Sample Preparation Tool using Acoustic

We have successfully developed a nucleic acid extraction system based on a microacoustic lysis array coupled to an integrated nucleic acid extraction system all on a single cartridge. The microacoustic lysing array is based on 36o Y cut lithium niobate, which couples bulk acoustic waves (BAW) into the microchannels. The microchannels were fabricated using Mylar laminates and fused silica to form acoustic‐fluidic interface cartridges. The transducer array consists of four active elements directed for cell lysis and one optional BAW element for mixing on the cartridge. The lysis system was modeled using one dimensional (1D) transmission line and two dimensional (2D) FEM models. For input powers required to lyse cells, the flow rate dictated the temperature change across the lysing region. From the computational models, a flow rate of 10 μL/min produced a temperature rise of 23.2 oC and only 6.7 oC when flowing at 60 μL/min. The measured temperature changes were 5 oC less than the model. The computational models also permitted optimization of the acoustic coupling to the microchannel region and revealed the potential impact of thermal effects if not controlled. Using E. coli, we achieved a lysing efficacy of 49.9 ± 29.92 % based on a cell viability assay with a 757.2 % increase in ATP release within 20 seconds of acoustic exposure. A bench‐top lysing system required 15‐20 minutes operating up to 58 Watts to achieve the same level of cell lysis. We demonstrate that active mixing on the cartridge was critical to maximize binding and release of nucleic acid to the magnetic beads. Using a sol‐gel silica bead matrix filled microchannel the extraction efficacy was 40%. The cartridge based magnetic bead system had an extraction efficiency of 19.2 %. For an electric field based method that used Nafion films, a nucleic acid extraction
Liver esterase polymorphisms in sepat Siam (Trichogaster pectoralis)

SUMMARY Esterase D and general esterases (which use a- or J3-naphthyl acetate as substrates) were investigated electrophoretically in the paddy field fish, Trichogaster pectoralis. Variants were observedfor these enzymes. It is hypothesized that esterase D phenotypes are due to two codominant alleles at an autosomal locus, and that four loci are involved in the control of the general esterases.

Form, function and flow in the plankton : jet propulsion and filtration by pelagic tunicates

Abstract : Trade-offs between filtration rate and swimming performance among several salp species with distinct morphologies and swimming styles were compared. Small-scale particle encounter at the salp filtering apparatus was also explored. Observations and experiments were conducted at the Liquid Jungle Lab, off the Pacific coast of Panama in January 2006 through 2009. First, time-varying body volume was calculated by digitizing salp outlines from in situ video sequences. The resulting volume flow rates were higher than previous measurements, setting an upper limit on filtration capacity. Though each species possessed a unique combination of body kinematics, normalized filtration rates were comparable across species, with the exception of significantly higher rates in Weelia cylindrica aggregates, suggesting a tendency towards a flow optimum. Secondly, a combination of in situ dye visualization and particle image velocimetry (PIV) measurements were used to describe properties of the jet wake and swimming performance variables including thrust, drag and propulsive efficiency. All species investigated swam via vortex ring propulsion. Though Weelia cylindrica was the fastest swimmer, Pegea confoederata was the most efficient, producing the highest weight-specific thrust and wholecycle propulsive efficiency. Weak swimming performance parameters in Cyclosalpa affinis, including low weight-specific thrust and low propulsive efficiency, may be compensated by comparatively low energetic requirements. Finally, a low Reynolds number mathematical model using accurately measured parameters and realistic oceanic particle size concentrations showed that submicron particles are encountered at higher rates than larger particles.

Exploring Configurable Congestion Control Feature of UDT Protocol

TCP becomes inefficient when the Bandwidth of the network and delay increases, because slow loss-recovery, a RTT bias inherent in its AIMD congestion-control algorithm, and the bursting data flow caused by its window control. To overcome this problem an application-level is built on top of UDP, called UDP based data Transfer Protocol, or UDT. UDT protocol contains the protocol design and its own congestion control algorithm which is also a framework for configuring new congestion control algorithm. UDT is a high performance data transport protocol, which is mainly, designed for bulk data transfer over high speed wide area networks. It is extended with Configurable Congestion Control to new enhanced versions called UDT/CCC, which supports a wide variety of control algorithms, including TCP algorithms. It is a configurable or reusable user space network stack on which a new congestion control algorithm can be easily implemented, deployed and evaluated. In this paper the potential of the UDT/CCC framework is analyzed by implementing the new control algorithms which is inherited from the CCC. Two types of control algorithm are implemented which is of type Rate based and Window based, after implementing the performances are to be obtained.
Overview of the biosphere-aerosol-cloud-climate interactions (BACCI) studies

Here we present research methods and results obtained by the Nordic Centre of Excellence Biosphere–Aerosol–Cloud– Climate Interactions (BACCI) between 1 January 2003 and 31 December 2007. The centre formed an integrated attempt to understand multiple, but interlinked, biosphere–atmosphere interactions applying inter and multidisciplinary approaches in a coherent manner. The main objective was to study the life cycle of aerosol particles and their importance on climate change. The foundation in BACCI was a thorough understanding of physical, meteorological, chemical and ecophysiological processes, providing a unique possibility to study biosphere–aerosol–cloud–climate interactions.

Control Laboratory PARAMETER ADAPTIVE CONTROL FOR A CLASS OF NONLINEAR SYSTEMS

An adaptive state feedback control algorithm is developed for a class of nonlinear systems having unknown parameters which enter the dynamic model in a linear fashion. Provided that certain matchability conditions are satisfied, the tracking error between the nonlinear plant and a linear reference model tends to zero for any feasible initialization of parameter estimates. Synthesis of the controller does not require that the unknown parameters belong to spe­ cified intervals of uncertainty. Simulation examples illustrate the application and performance of the control algorithm.
HOMOLOGY 3-SPHERES BOUNDING ACYCLIC 4-MANIFOLDS

Let Σ(a1, a2, . . . , an) be a Seifert fibered homology 3-sphere with a1 even. We show that if μ(Σ(a1, a2, . . . , an)) = 1 mod 2, then the class of Σ(a1, a2, . . . , an) has infinite order in the homology cobordism group of homology 3-spheres. In the proof we use Seiberg-Witten’s monopole equation on fourdimensional V-manifolds.
Doubly-robust Estimators in Observational Studies with and without a Stratified Subsample by Xiaofei

BAI, XIAOFEI. Doubly-robust Estimators in Observational Studies with and without a Stratified Sub-sample. (Under the direction of Anastasios A. Tsiatis.) In this dissertation, we study semiparametric estimators in observational survival analysis. Observational studies are frequently conducted to compare the effects of two treatments on survival. For such studies we must be concerned about confounding; that is, there are covariates that affect both the treatment assignment and the survival distribution. With confounding the usual treatment-specific Kaplan-Meier estimator might be a biased estimator of the underlying treatment-specific survival distribution and the ordinary log rank test might lead to biased result. This dissertation has three parts. In Chapter 1, we use semiparametric theory to derive doubly robust estimators (and their asymptotic variance) of the treatment-specific survival distributions and the difference in the treatment-specific survival distributions in the case when the collected covariates are enough to adjust for all confounding in the main study. In Chapter 2, we develop treatment-specific survival estimator in the case when we further conduct a stratified sampling substudy to collect additional potential confounding covariates. In Chapter 3, we develop log rank type test statistics to test for the difference in overall treatment curves, in both case of main study and substudy. All developed methods are applied to a real data example along with different simulation scenarios. © Copyright 2014 by Xiaofei Bai
