DASRS Rest: Um Algoritmo Eficiente de Detecção de Anomalias em Tempo Real para Data Centers

A large amount of equipment, with different configurations, and regular software and hardware upgrades on data centers, make it challenging to use monitoring systems based on threshold setting. This paper proposes to use anomaly detection for fault prevention. It presents the Decreased Anomaly Score by Repeated Sequence (DASRS) Rest algorithm, which detects anomalies without requiring prior knowledge of the monitored service. We evaluate DASRS Rest performance using the Numenta Anomaly Benchmark (NAB) framework. The proposed algorithm has good accuracy results, the lowest memory consumption, and is the fastest when compared to several state-of-the-art algorithms. Resumo.

The chloride diffusion characteristics of concrete: approximative determination by linear regression analysis

The complexity of the equation derived from Fick's second law of diffusion is a hindrance when the chloride diffusion characteristics have to be determined by laboratory tests. Only non-linear curve-fitting is available, e.g. by applying the Gauss-Newton method. However, a simple approximation makes it possible to determine the chloride diffusion characteristics by linear curve-fitting and the paper describes how it is possible to obtain a good estimate by applying a small pocket-computer

Magneto-mechanical properties of elastic hybrid composites

Abstract The paper gives an overview of tunable elastic magnetic composites based on silicon rubber matrix highly filled with a magnetic soft and hard filler. The magnetic soft phase, which is represented by iron microparticles, allows active control of the physical properties of the composites, while the magnetically hard phase (e.g. neodymium–iron–boron alloy microparticles) is mainly responsible for passive adjustment of the composite. The control is performed by the application of an external magnetic field in situ, and passive adjustment is performed by means of pre-magnetization in order to change material remanent magnetization, i.e. the initial state. The potential and limits of active control and passive tuning of these composites in terms of their magneto-mechanical behavior are presented and discussed.
Isquemia miocárdica por consumo de dibutilona

Las catinonas sintéticas son drogas estimulantes de síntesis, comercializadas en el mercado ilegal por sus propiedades estimulantes y perturbadoras del sistema nervioso central, para su uso recreativo, solas, o como adulterantes de cocaína y derivados anfetamínicos. A nivel mundial existe un número creciente de reportes de intoxicaciones agudas y complicaciones por consumo de estas sustancias. En Uruguay fueron detectadas por primera vez en el año 2015, existiendo una información epidemiológica muy limitada. Las catinonas sintéticas no se detectan por las técnicas inmunocromatográficas disponibles en los laboratorios de los servicios de urgencias de nuestro país. Se describe el primer caso de intoxicación por una catinona sintética (dibutilona) en Uruguay, en un paciente de 45 años, por consumo de un polvo vendido como “éxtasis”, presentando como complicación un síndrome coronario agudo, con una buena evolución posterior. La confirmación diagnóstica se realizó mediante su detección en orina por cromatografía de gases acoplada a espectrometría de masas. La estructura química de la dibutilona y su mecanismo de acción explican las manifestaciones clínicas y la complicación isquémica por vasoespasmo coronario. En ausencia de una noción clara de exposición y ante la situación epidemiológica actual, la presencia de un cuadro clínico compatible con una droga estimulante y resultado negativo para cocaína y anfetaminas en estudios inmunocromatográficos, debe hacer plantear la sospecha de otros estimulantes de síntesis como las catinonas, tal como ocurrió en este caso.
Evaluating the influence of noise emitted by environmental enrichment equipment in routine farrowing management practices

The installation of fans and rooftop sprinklers in swine housing and management facilities can increase noise intensity and may impair workers' hearing health over longs periods of time; therefore, an assessment of the piglets’ stress during invasive practices was made. This study set out to evaluate the noise intensity emitted by environmental enrichment devices (fans and rooftop sprinklers) and by piglets restrained for body temperature assessments and its effect on animal welfare and on the hearing health of workers exposed to it for long periods. Twenty piglets ranging in age from five to twenty days were observed. The sow gestation area was divided into a cooled (fans and rooftop sprinklers) and uncooled area. Two decibel meters were used to measure noise intensity, one for the general noise in the facilities and the other for the piglets, with five-minute intervals between assessments. Digital thermometers were used to take the rectal temperature, and infrared thermometers were used to take the body surface temperature. Fixed-effects ANOVA for the housing environment and periods and multiple comparisons at a significance level of 5% were applied. The average dorsal temperature of the piglets was 36 °C ± 1.2 in the cooled area and 38.4 °C ± 0.5 in the uncooled area. In both periods, the average maximum noise intensity was over 100 decibels. In the afternoon, the maximum intensity was higher for the uncooled environment. The results indicate that neither the fans nor the rooftop sprinklers installed in the facilities nor the squealing piglets during restraint affect the noise intensity of the environment. However, the noise intensity demonstrates the piglets’ stress and the need for protective equipment to preserve the workers’ hearing health.
A Joint Theory and Experimental Project in the Synthesis and Testing of Porous COFs for On-Board Vehicular Hydrogen Storage

Conventional storage of large amounts of hydrogen in its molecular form is difficult and expensive because it requires employing either extremely high pressure gas or very low temperature liquid. Because of the importance of hydrogen as a fuel, the DOE has set system targets for hydrogen storage of gravimetric (5.5 wt%) and volumetric (40 g/L) densities to be achieved by 2015. From our continuous efforts on hydrogen storage, it is believed that metalation of highly porous solids with high-valence metals is promising and provides a rational direction to realize high volumetric hydrogen density near room temperature. This grant was focused on the study of high surface area covalent organic frameworks (COFs) with these specific objectives (1) to introduce potential metal binding sites through the COF synthesis and (2) to implement metalation experiments and evaluate their respective hydrogen adsorption properties. To maximize our efforts, simulation calculations were also performed (prior to experiments) for the prediction of binding enthalpy of hydrogen for molecular building units containing transition metals and promising COF structures to increase volumetric hydrogen uptake at room temperature. In this effort, first molecular building units with optimal binding energy for hydrogen storage (20 kJ/mol) were designed by quantum mechanical (QM) methods. Employing more » these results, it was revealed that one of metalated COFs takes up 60 g/L (total) of H2 at 100 bar and 298 K. To realize proposed COF structures, chemistry of COF synthesis has been developed; for instance, new air stable COFs were synthesized via hydrazone (COF-41 to 43) and imine condensation (COF-301, 320, 340, and 366) and some of them were tested the effect on metalation. Finally, a new triazine COF with high volumetric hydrogen uptake capacity was presented as a proposed future direction. « less
Coronavirus Ethics: Judgments of Market Ethics in a Pandemic

COVID-19 has required major changes in behavior and created significant health and economic concerns for many individuals. In this context, we have explored ethical judgments as part of a larger project on market ethics. We found that marketing practices judged as highly unethical before the pandemic, were judged to be much less unethical one year later. Of the questionable practices examined during the lockdown, those related to the pandemic (e.g., price gouging on hand sanitizer) were generally evaluated the most unethical, equal to or more unethical than the most egregious practices previously tested. Experience of lockdown affected ethical judgments, with number of people in the household, lockdown duration, and time spent on social media associated with less unethical judgments. Broader effects of the pandemic, including negative affect, diminished well-being, and financial difficulties, were also associated with less ethical concern. Implications for policymakers and marketing practitioners are discussed.
Reactive adsorption of low concentration methyl mercaptan on a Cu-based MOF with controllable size and shape

A copper-based metal organic framework (MOF-199) with controllable size and shape was synthesized and used to remove gaseous methyl mercaptan (CH3SH). Characterizations of the synthesized MOF-199 samples before and after desulfurization were carried out by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and X-ray photoelectron spectroscopy (XPS) to observe the adsorption mechanism of CH3SH on MOF-199. The adsorption performance of the synthesized MOF-199 materials and commercialized activated carbon (AC) and Cu loaded AC were evaluated by breakthrough experiments. All three synthesized MOF-199 materials show better performance than commercialized AC. The morphology and texture of MOF-199 materials have great influence on the performance of the adsorption process. The MOF-199 material synthesized by a hydrothermal method exhibited the highest sulfur compound capacity among the synthesized MOF-199 materials (74.7 mg of CH3SH/1 g MOF-199). The color change of MOF-199 during the CH3SH capturing process, indicated a strong interaction between the unsaturated copper sites and –SH group which finally formed CuS and gave rise to obvious damage to the MOF structure.

An Empirical Study of The Effect of Urban Street Park on Park Users’ Mood

Urban street park is an important part of the urban park system, and also a kind of park with high contact frequency in people’s daily life, so it has potential promoting effect on people’s mental health. In order to test the effect of urban street park on the mood state of park users, this study took a street garden in Hefei of China as the research site and used stratified sampling method to carry out a questionnaire survey on park users visiting the park at different time periods. One way ANOVA results show that there is a significant difference in the mood changing scores among park users in the different groups of the satisfaction of the environment of the green landscape space, the resting space and the fitness space. Regression analysis results show that the park users’ satisfaction with the environment of the green landscape space and the resting space and the time spent in the park are positively correlated with their mood changes, indicating that the better quality of the environment of the green landscape space and the resting place of the park, the longer the park users staying in the park, the more positive effect of the park environment on users’ mood state. The conclusion provides a scientific basis for the related research on the mental health effects of urban parks.
Production of X-RAYS using X-RAY Tube

X-rays are usually the most common form of electric magnetic radiation. Technological developments in imaging have resulted in increasingly powerful and guided X-ray rays, and also growing use of visible light in adolescence microbial tissues and structural elements of materials like concrete. Since its discovery in 1895 X-ray has been commonly used in medication and some areas of technology, science and engineering. The X-ray tube is an essential component of each X-ray union, and in its early stages scientists and doctors utilized gas ion tubing. X-rays are generating because fast-moving electrons suddenly decelerate when they collision with the target anode and interact with it. Therefore, x-ray tube absorbs and dissipates a large heat charge in order to achieve adequate radiation output for digital radiology influencing the structure and function of a x-ray source. An x-ray tube’s key components include electrode and counter electrode frames, rotor and stator, and tube cover. The X-rays generated have waveform features similar to other electromagnetic waves. As x-rays come across matter, the small wavelength of radiation defines their property. Most of the materials are transparent to the x-ray and radiation will not transmit lead and other dense materials. Throughout this paper, we discuss X-ray machine, characteristics and features of x-ray, X-ray source modules, x-ray applications in a broad range of domains to discuss x-ray background, manufacturing and x-ray identification.
Analysts’ EPS Forecasts: The Effects of Forecast Uncertainty and Forecast Precision on Investors’ Judgments

In this study, I use an experiment to investigate the joint effects of forecast precision and forecast uncertainty on investors’ judgments of the reliability of analysts’ EPS forecasts. Results indicate that participants’ judgments of forecast reliability are not influenced by forecast uncertainty when precise analyst EPS forecasts are presented. In contrast, participants’ judgments of forecast reliability are higher when forecast uncertainty is low than when it is high when round forecasts are presented. Further, I find that investors’ judgments of the overall conditions under which the forecasts are made are influenced (not influenced) by forecast uncertainty, and that the relationship between forecast uncertainty and forecast reliability is mediated (not mediated) by investors’ judgments of the overall conditions under which the forecasts are made when round (precise) forecasts are presented. My findings are informative to analysts and investors because it provides insights into how investors perceive and react to rounding in analysts’ EPS forecasts under differing levels of earnings uncertainty.
Performance Enhancement of Tri‐Cation and Dual‐Anion Mixed Perovskite Solar Cells by Au@SiO2 Nanoparticles

Tri‐cation and dual‐anion mixed perovskites have been widely utilized in perovskite solar cell (PSC) applications due to their novel properties such as high absorption, high stability, and low cost. To commercialize the PSCs, further improving the device performance without detrimentally changing the device configuration is important at present. Herein, Au@SiO2 nanoparticles (NPs) are introduced to modify the interface between mesoporous TiO2 (mp‐TiO2) and mixed perovskite with increased main photovoltaic parameters of the device, resulting in a ≈29% enhancement of power conversion efficiency (PCE) from 15.8% to 20.3%. The origins of the enhancement have been studied by exploring the optical absorption, optical power distribution, and charge carrier behaviors within the system. The small perturbation transient photovoltage measurement exhibits prolonged charge carrier lifetimes after the Au@SiO2 NPs incorporation, and time of flight photoconductivity measurement shows that charge carrier mobilities of this system are also enhanced. These characteristics make metallic nanostructures a promising functional material in facile tuning of the charge carriers transport and further boosting the PCE of the PSCs.

Kinetics of Iron Retention by Typic Torriorthent and Typic Haplocalcid Soils Supplied with Some Micronutrients

Abstract Most soils contain sufficient amounts of Fe for plant use; however, most of these amounts are found mainly in unavailable forms for plant use. Applying Fe to soil is associated with rapid sorption by soil; also, application of micronutrient elements might affect Fe availability in soil. This paper discuses the effects of applying Fe, Zn or Mn fertilizers on AB-DTPA-Fe extractability; also it investigates the fitness of Fe sorption data to different kinetic models to explore the possible mechanism or mechanisms that might affect Fe sorption in soil. The results reveal that application of either Fe, Mn or Zn had no significant effect on AB-DTPA- Fe in the Typic Torriorthent and Typic Haplocalcid soils. Mixed application of Fe + Mn, Fe + Zn, Zn + Mn or Fe+Zn+Mn increased AB- DTPA- Fe extractability significantly in both soils. The increase in the amount of AB-DTPA-Fe was about 4 folds in the Typic Torriorthent soil, and 40 folds in the Typic Haplocalcid one. Fitting the sorption data of Fe of nine periods of contact between soil and added metals to the different kinetic models showed that the simple Elovich and parabolic diffusion models seemed to be the most fitting models for describing Fe sorption kinetics in the Typic Torriorthent soil, while the first order model was the most fitting model to describe Fe sorption kinetics in the Typic Haplocalcid soil.
