High Temperature Versus Geomechanical Parameters of Selected Rocks – The Present State of Research (2013)

This paper presents the current state of knowledge concerning the examination of the impact of increased temperatures on changes of geomechanical properties of rocks. Based on historical data, the shape of stress–strain characteristics that illustrate the process of the destruction of rock samples as a result of load impact under uniaxial compression in a testing machine, were discussed. The results from the studies on changes in the basic strength and elasticity parameters of rocks, such as the compressive strength and Young’s modulus were compared. On their basis, it was found that temperature has a significant effect on the change of geomechanical properties of rocks. The nature of these changes also depends on other factors (apart from temperature). They are, among others: the mineral composition of rock, the porosity and density. The research analysis showed that changes in the rock by heating it at various temperatures and then uniaxially loading it in a testing machine, are different for different rock types. Most of the important processes that cause changes in the values of the strength parameters of the examined rocks occured in the temperature range of 400 to 600 °C.
Automated-generating test case using UML statechart diagrams (2003)

Software testing plays a major role in software development because it accounts for a large part of the development cost. Moreover, manual testing technique always makes a problem. Consequently, this paper proposes the automatic testing technique to solve partially the testing process. This technique can automatically generate and select test cases from UML statechart diagrams. Firstly, we transform this diagram into intermediate diagram, called Testing Flow Graph (TFG), explicitly identify flows of UML statechart diagrams and enhance for testing. Secondly, from TFG we generate test case using the testing criteria that is the coverage of the state and transition of diagrams. Finally, the evaluation is performed using mutation analysis to assess the fault revealing power of our test cases.
Development of a model and computer code to describe solar grade silicon production processes. Final report (1979)

Models and computer codes which may be used to describe flow reactors in which high purity, solar grade silicon is produced via reduction of gaseous silicon halides are described. A prominent example of the type of process which may be studied using the codes developed in this program is the SiCl/sub 4//Na reactor currently being developed by the Westinghouse Electric Corp. During this program two large computer codes were developed. The first is the CHEMPART code, an axisymmetric, marching code which treats two-phase flows with models describing detailed gas-phase chemical kinetics, particle formation, and particle growth. This code, based on the AeroChem LAPP (Low Altitude Plume Program) code can be used to describe flow reactors in which reactants mix, react, and form a particulate phase. Detailed radial gas-phase composition, temperature, velocity, and particle size distribution profiles are computed. Also, depositon of heat, momentum, and mass (either particulate or vapor) on reactor walls is described. The second code is a modified version of the GENMIX boundary layer code which is used to compute rates of heat, momentum, and mass transfer to the reactor walls. This code lacks the detailed chemical kinetics and particle handling features of the CHEMPART code but has the virtue of running much more rapidly than CHEMPART, while treating the phenomena occurring in the boundary layer in more detail than can be afforded using CHEMPART. These two codes have been used in this program to predict particle formation characteristics and wall collection efficiencies for SiCl/sub 4//Na flow reactors. Results are described.
A highly efficient method for liquid and solid cultivation of the anaerobic hyperthermophilic eubacterium<i>Thermotoga maritima</i> (2006)

An efficient and economical medium--Thermotoga maritima basal medium (TMB)--was designed for the cultivation of T. maritima under either liquid or solid conditions. When the broth was flushed with N2 or CO2 throughout cell growth in a 10-L fermentor (pH controlled to 6.5), the maximum cell density (OD600) on TMB containing 1% glucose rose to 2.0 or higher (1.63 x 10(9) cells mL(-1)). Sheath-less cells observed by electron microscopy were captured during growth in the fermentor. Using a two-layer plating method, isolated single-well colonies were consistently obtained within 24 h on the TMB in modified tissue culture flasks. The minimal inhibitory chloramphenicol concentrations for T. maritima on TMB agar were 5 microg mL(-1) after 24 h and 48 h, and 25 microg mL(-1) at 72 h.
Hybrid content filtering and reputation-based popularity for recommending blog articles (2014)

Purpose – Social bookmarking is a system which allows users to share, organise, search and manage bookmarks of web resources. However, with the rapid growth in the production of online documents, people are facing the problem of information overload. Social bookmarking web sites offer a solution to this by providing push counts, which are counts of users’ recommendations of articles, and thus indicate the popularity and interest thereof. In this way, users can use the push counts to find popular and interesting articles. A measure of popularity-based solely on push counts, however, cannot be considered a true reflection of popularity. The paper aims to discuss these issues. Design/methodology/approach – In this paper, the authors propose to derive the degree of popularity of an article by considering the reputation of the users who push the article. Moreover, the authors propose a novel personalised blog article recommendation approach which combines reputation-based group popularity with content-based filtering (CBF), for the recommendation of popular blog articles which satisfy users’ personal preferences. Findings – The experimental results show that the proposed approach outperforms conventional CBF, item-based and user-based collaborative filtering approaches. The proposed approach considering reputation-based group popularity scores on neighbouring articles indeed can improve the recommendation quality of traditional CBF method. Originality/value – The recommendation approach modifies CBF method by considering the target user's group preferences, to overcome the limitation of CBF which arises from the recommending only items similar to those the user has previously liked. Users with similar article preferences (profiles) may form a group of users with similar interests. A group's preferences may also reflect an individual's preferences. The reputation-based group preferences of the target user's group can be used to complement the target user's preferences.
User Centric Design of an NFC Mobile Wallet Framework (2011)

Near Field Communication (NFC) among various other things, allows end-users to enjoy contactless mobile services such as credit cards, transport tickets, office access etc. using NFC mobile phones. Such services are placed as software applications inside the secure-chip hardware of the NFC phone – often termed as a Secure Element (SE). Bringing these contactless smart-card services into mobile phones raises the need to allow the end-users to interact and control the information and the communication with secure-chip applications. The display of a mobile phone can easily allow such functionalities as graphical user interface applications. This thesis terms such applications as NFC mobile wallet applications where a mobile wallet is the container for all of these applications. A mobile wallet application for a single service is intended to be used on various phone platforms and often there is a need to keep the consistency and uniform functionalities between the designs. Primarily, this thesis aims to provide the means for the service providers (and for the developers) to design and develop one single wallet application for a particular NFC service and deploy it on various phone platforms using the support of a wallet framework. In order to achieve that, this thesis aims to identify a minimal but adequate set of user interaction functionalities for the mobile wallet services and include their support in the wallet framework. Due to time constraints, only three NFC services: payment, access control, and transport were investigated. Then a lightweight wallet framework was designed that includes support to implement the identified user interaction functionalities as a set of application programming interfaces (APIs) to develop interoperable wallet applications. There were complexities while designing the framework, for example, limited NFC supports on various phone platforms at this writing; however, the thesis achieved the desired goals at the end. Two prototype wallet applications were developed on the basis of the identified minimal functionalities and the wallet framework support. Usability testing was conducted for the prototypes to find usability issues and the applicability of the functionalities in the wallet interface. The result was very positive; the users had little trouble interacting with the wallet applications. Several recommendations were noted from the usability testing mainly on navigating the interface and consistency in the design, which are summarized for the developers as guidelines to develop wallet applications.
A Model-Based Systems Engineering Methodology for Employing Architecture In System Analysis: Developing Simulation Models Using Systems Modeling Language Products to Link Architecture and Analysis (2016)

This dissertation contributes to model-based systems engineering (MBSE) by formally defining an MBSE methodology for employing architecture in system analysis (MEASA) that presents a comprehensive framework detailing the relationship between system architecture products and external models and simulations used to analyze system performance and feasibility. Specifically, the research combines the use of Systems Modeling Language (SysML) products and operational simulation models to support assessment of system requirements for systems engineering. The MBSE MEASA transforms operational needs into preferred system configurations through the analysis of detailed simulation models. The research does this by using designed experiments to generate architecture tradespace visualizations that highlight the impact that system design parameters, system-environment interactions, system operational implementation, and system component interactions have on system performance. The research demonstrates a procedure for iterations of the methodology when analysis suggests potentially impactful design, operational, or environmental variables (as well as potential interactions between those variables). The research develops and analyzes notional architecture products and simulation models of United States Navy mine warfare systems to demonstrate an application of the MBSE MEASA.
Hormone receptor-positive early breast cancer: controversies in the use of adjuvant chemotherapy (2009)

Current adjuvant treatments for operable breast cancer include chemotherapy, endocrine therapy in hormone receptor-positive tumors, and trastuzumab for HER2-positive tumors. Metanalyses of randomized trials show that in patients with hormone receptor-positive breast cancer, the effects of endocrine therapy and chemotherapy on survival are non-mutually exclusive. Most of these patients are therefore considered candidates to combined treatment. Recently, however, the endocrine responsiveness of tumors has been redefined on clinical, histopathological, and molecular bases. An emerging concept is that as endocrine responsiveness increases, chemoresponsiveness decreases. In the adjuvant setting, therapeutic choices are often based on small projected improvements in clinical outcomes. As a consequence, the role of chemotherapy and traditional management algorithms in patients with hormone receptor positive is being challenged. This review will address the current controversy regarding the role of adjuvant chemotherapy, including the newer anthracycline and taxane-based programs, in these patients.
Superficial Bacterial Contamination of Bovine Carcasses at Blida Slaughterhouse (Algeria) (2013)

The purpose of our work is to evaluate the superficial bacteriological quality of bovine carcasses at Blida slaughterhouse; quantitatively, by counting the total coliforms, fecal coliforms and Escherichia coli and qualitatively by the research for Salmonella spp. at three (3) different bovine carcasses sites. Thirty (30) carcasses have been sampled just after evisceration by swabbing method on a surface of 196 cm² making use of house pads. The results of bacterial counts have revealed the absence of Salmonella in the 90 analyzed samples. As for the total coliforms, fecal coliforms and E. coli, the registered bacterial loads reached 2.59±0,29 log cfu/cm², 1.53±0,20 log cfu/cm² and 0.49±0,11 log cfu/cm², respectively. Among the tested sites, the neck is the most contaminated. Ranking the thirty carcasses according to their bacteriological qualities showed that 12 carcasses (40%) had a satisfactory quality, 08 carcasses (26.67%) have been acceptable and 10 carcasses (33.33%) were of unsatisfactory quality. Our results reflect poor conditions of slaughtering and handling of carcasses, wherefrom the hygiene deficiencies at Blida slaughterhouse.
Reducing the cost of beef production through genetic improvement in residual feed intake: Opportunity and challenges to application 1 (2003)

There is considerable individual animal variation in feed intake above and below that expected or predicted on the basis of size and growth rate. This difference in intake is calculated as residual (or net) feed intake (RFI). Genetic variation in RFI of beef cattle exists both during growth (slaughter generation and replacement females; heritability estimates since 1996 range from 0.16 to 0.43) and in adult cattle (the breeding herd; the one published heritability estimate is 0.23). Evidence shows that selection for lower RFI measured postweaning will lead to a decrease in feed intake by young cattle and by cows, with no compromise in growth performance or increase in cow size. Results from a single generation of divergent selection on postweaning RFI between 8 to 12 mo of age demonstrated favorable correlated changes in average daily feed intake (9.2 ± 0.2 vs. 9.8 ± 0.2 kg/d), RFI (−0.20 ± 0.11 vs. 0.17 ± 0.10 kg/d), and feed:gain ratio (F:G; 7.0 ± 0.2 vs. 7.6 ± 0.2 kg/kg) in Angus feedlot steers. In Angus cattle, the genetic correlation between postweaning RFI with av- erage daily feed intake by the cow is high (0.64), and
Multivariate Image Analysis of Flames for Product Quality and Combustion Control in Rotary Kilns (2006)

Rotary kilns are widely used in industry to achieve effective gas−solid heat transfer at high temperatures by direct contact with hot flue gases obtained by combustion. However, various disturbances related to nonpremixed combustion often used in practice introduces undesired variability in product quality and forces overheating, especially when obtaining the desired quality is dependent upon reaching a minimal solids discharge temperature. This paper investigates the use of digital RGB flame images and multivariate image analysis (MIA) techniques to quantify these combustion-related variations and to predict the future behavior of product quality. Very good solids discharge temperature forecasts were obtained over a time window running from current time t to about the mean residence time within the kiln using only a single flame image collected at time t. This information will be used to develop innovative automatic flame image-based control schemes to improve quality control and reduce fuel consumption.
Elasto-viscoplastic constitutive equations for the description of glassy polymers behavior at constant strain rate (2006)

In this study, a modelization of the viscoplastic behavior of amorphous polymers is proposed, from an approach originally developed for metal behavior at high temperature, in which state variable constitutive equations have been modified. A procedure for the identification of model parameters is developed through the use of experimental data from both uniaxial compressive tests extracted from the literature and uniaxial tensile tests performed in this study across a variety of strain rates. The numerical algorithm shows that the predictions of this model well describe qualitatively and quantitatively the intrinsic softening immediately after yielding and the subsequent progressive orientational hardening corresponding to the response of two polymers, amorphous polyethylene terephthalate and rubber toughened polymethyl methacrylate.

The fourth lecture introduces Grand Unified Theories, with emphases on general principles and on neutrino masses and mixing. Finally, the last lecture contains short discussions of some further topics, including supersymmetry breaking, gauge-mediated messenger models, supergravity, strings and $M$ phenomenology.
A significance test for classifying arma models (1996)

Abstract Given that the Euclidean distance between the parameter estimates of autoregressive expansions of autoregressive moving average models can be used to classify stationary time series into groups, a test of hypothesis is proposed to determine whether two stationary series in a particular group have significantly different generating processes. Based on this test a new clustering algorithm is also proposed. The results of Monte Carlo simulations are given. Keywords: Significance testtime SeriesARMA Models

Methods of brood protection as a basis for reclassification of the Spirorbinae (Serpulidae) (1969)

In a taxonomic review, nine previously defined subgenera are adopted and a tenth Marsipospira subgen. aov. is proposed for about four species, with S. striatus Quiäreux (1963) as the type. These all retain their embryos in a thoracic brood pouch, fixed to a modified dorsal tentacle, and also possess a translucent tube, often with transverse ridges, an opercular talon, with lateral lobes and/or lateral knobs, and vestiges of a fourth thoracic segment. The remaining species, numbering more than 74, may be grouped in six subgenera with egg string incubation and three with opercular incubation. These three main methods of incubation are likely to have been derived independently, from ancestral serpulids spawning into their tubes. The distribution of abdominal uncini helps to characterize subgenera. In Spirorbis, Spirorbella, Pileolaria, Leodora and Janua the abdominal tori are not very asymmetrical, those on the concave side being only slightly larger than the others. In Pileolaria the largest abdominal tori are usually found in the posterior half of the abdomen, but in other subgenera they usually lie in the anterior half of that region. Paralaeospira, Greets and Marsipospira have the abdominal tori very asymmetrically developed and usually absent from the convex side. This marked asymmetry is often associated with the tubes being translucent, smooth and presumably slippery on the inside. It may thus be related to the anchorage problem, during rapid withdrawal. The asymmetrically developed traces of a fourth thoracic segment, with which the abdominal asymmetry is often correlated, seem unlikely to be primitive survivals. They may rather be incidental expressions of genotypes evolved through selection pressure which was concerned primarily with anchorage problems in the abdominal region.
THERMOELECTRIC NUCLEAR FUEL ELEMENT QUARTERLY PROGRESS REPORT - JULY- SEPTEMBER, 1960 (1960)

Seven binary and tennary uranium chalcogenides were prepered for melting in helium-filled tantalum bombs. The USTe material is to be swaged into a test device for thermoelectric measurements. Commercial purity PbTe is being processed in a graphite-steel bomb to learn if it can be used to realize substantial cost savings. Property measurement results are listed for various telluride thermoelectric materials and elements, and for various devices for irradiation evaluations. Life tests of PbTe elements have been running for 1700/ sup +/ hr. Results are analyzed for a Westinghouse Testing Reactor (WTR) irradiation test sample. Preinstrumentation techniques were developed to improve the amount and quality of information beiug secured from swaged elements under test. Calculations were made on thermal cascaded thermoelectric elements, and powder metallurgy dies for producing such elements were procured. Results of compatibility studies of PbTe and GeTe with various structural materials were reported. Data were obtained for the Case II thermoelectric reactor core designs. The design features high-enrichment fuel, a Be-UO/sub 2/ fuel matrix with a Cu-Fe inner electrical conductor and an aluminum outer conductor. Work began on the evaluation of a low-enrichment (Case III) design. (auth)
Loop transformations leveraging hardware prefetching (2018)

Memory-bound applications heavily depend on the bandwidth of the system in order to achieve high performance. Improving temporal and/or spatial locality through loop transformations is a common way of mitigating this dependency. However, choosing the right combination of optimizations is not a trivial task, due to the fact that most of them alter the memory access pattern of the application and as a result interfere with the efficiency of the hardware prefetching mechanisms present in modern architectures. We propose an optimization algorithm that analytically classifies an algorithmic description of a loop nest in order to decide whether it should be optimized stressing its temporal or spatial locality, while also taking hardware prefetching into account. We implement our technique as a tool to be used with the Halide compiler and test it on a variety of benchmarks. We find an average performance improvement of over 40% compared to previous analytical models targeting the Halide language and compiler.
GLEAMS: Groundwater Loading Effects of Agricultural Management Systems (1987)

ABSTRACT GLEAMS (Groundwater Loading Effects of Agricul-tural Management Systems) is a mathematical model developed for field-size areas to evaluate the effects of agricultural management systems on the movement of agricultural chemicals within and through the plant root zone. This paper describes the concepts of the hydrology, erosion, and pesticide components of GLEAMS. Results of sensitivity analysis and validation with observed bromide and pesticide data are given. The validation includes comparisons of model simulations and observed soil concentrations in the root zone, and simulated and observed leaching losses.
