ARMA Processes and Reliability‐Based Design of Wastewater‐Treatment Facilities

The applicability of univariate uncorrelated, univariate ARMA, and diagonalized vector autoregressive moving average (ARMA) processes was studied and compared to published procedures for reliability‐based design of wastewater‐treatment plants. Three applications are presented. In the first application, influent biological oxygen demand (BOD) mass loading was simulated using a univariate, weekly periodic autoregressive process to calculate sustained peak loading. In the second application, three water‐quality variables were simulated jointly using a diagonalized vector autoregressive process to calculate potential nutrient deficiencies in activated sludge processes. In the third application, effluent BOD concentrations were simulated using a univariate autoregressive process to calculate the reliability of meeting permit limits of various durations. It was found that by more completely modeling the statistical structure of available historical data, the ARMA modeling techniques were effective for reliabili.
SISTEMAS DE CONTROL PARA LA PROTECCIÓN DE ESTRUCTURAS CIVILES SOMETIDAS A CARGAS DINÁMICAS CONTROL SYSTEMS FOR DYNAMIC LOADING PROTECTION OF CIVIL STRUCTURES

Excessive or prolonged vibrations in civil structures can produce annoyances in the users and damages in structural and nonstructural elements. These vibrations are determined by the dynamic parameters (mass, stiffness and damping), and is modifying these structural characteristics what reduces the response of the structure. The reduction of the structural response is the objective in the earthquake engineering an seismic design, guaranteeing a suitable strength, stiffness and ductility. In the past years have been purposed several alternatives to diminish the structural vulnerability, among them active, passive, hybrid and semi-active control systems which have been implemented in flexible structures (skyscrapers and suspension bridges) in Japan and the United States. This paper includes a brief historical summary of the development of these structural control systems and presents the state-of-the-art and state-of-the-practice of this technology. In addition, describes the limitations and advantages of the systems in the context of the structural seismic design and rehabilitation.
Emerging work practices of ICT-enabled mobile professionals

Currently, mobility is a significantly pervasive term; the concept is being widely used in multiple discussions including social, economic, political, and technological debates. However, the theoretical grounding of the concept is surprising unstable. This thesis aims to offer a theoretical foundation for the concept of mobility, particularly in contemporary work contexts. With support of information and communication technologies (ICTs) in general and mobile technology in particular, contemporary work activities are increasingly distributed and dynamically conducted in various locations. In such an emerging work environment, maintaining a highly level of 'mobility' is becoming critical for contemporary workers, particularly for mobile professionals. Based on the theoretical considerations on the concept of mobility, this thesis empirically explores the dynamic and heterogeneous nature of mobile professionals' work practices. In order to appreciate and explain the nature of mobility in contemporary work, this thesis specifically addresses the emerging work practices of mobile professionals. the data collection consisting of in-depth interviews and ad-hoc observations of sixty0two professional workers was conducted in Tokyo, Japan during the summer of 2002. Informed by the results of this qualitative field study, the thesis discusses a distinct mode of mobility in mobile professional work. The mode of mobility is characterised not only by extensive geographical movement but also by operational flexibility and intense interaction in mobile professional's dynamic work activities. Based on these theoretical and empirical discussions, this thesis aims: 1) to theoretically underpin our understanding of mobility in contemporary work contexts; 2) to offer empirically grounded implications for the post-bureaucratic, fluid organising of work, organisation, and technology.
InGaAsP-InP semiconductor microcavity geometries for annular Bragg reflection, optical switching, and sensing

One of the key mandates of modern optoelectronic research is the development of compact photonic integrated circuits, capable of performing many diverse functions for the generation, manipulation, and detection of light, all on a single chip. A key practical requirement for such circuits is the development of optical devices for the localization and processing of light within extremely small dimensions. In recent years, planar microring and microdisk resonators, in which light is confined by total internal reflection, have emerged as versatile photonic elements for filling this role. The high quality factors and long photon storage times associated with the whispering-gallery modes supported by these microcavities result in several technologically useful characteristics, including narrow-band filter response, and large resonant enhancement of the circulating electric field. These properties have been exploited in numerous passive and active device applications, including optical add/drop multiplexers, all-optical switches, and tunable lasers. This thesis describes the study of several unique ring-based optical microcavity geometries based upon the indium gallium arsenide phosphide/indium phosphide alloy semiconductor material system, undertaken in an effort to explore new optoelectronic architectures for confining and manipulating light. The first portion of this work involves the analysis and demonstration of a new microcavity geometry, in which cylindrical Bragg reflection is used for radial optical confinement, as an alternative to total internal reflection. In this class of structures, collectively known as annular Bragg resonators, light can be guided within a ring or pillar defect layer surrounded by cylindrical Bragg mirrors. Several microcavities based upon this configuration are designed and fabricated using a thin InGaAsP quantum well membrane. Using pulsed optical excitation, the characteristics of these structures as low threshold vertically emitting lasers is explored. Second, a total internal reflection-based coupled waveguide-resonator geometry, having applications to low power optical switching and modulation, is analyzed. This geometry makes use of the hybrid integration of a Mach-Zehnder interferometer with a racetrack resonator. Switching takes place using the Mach-Zehnder to control the coupling parameters in the vicinity of the critical coupling condition. Characterization of the static and dynamic output response of a thermooptically actuated InGaAsP-InP hybrid switch device demonstrates good ON-OFF switching contrast, microsecond response time, and reduced switching power in comparison with a conventional Mach-Zehnder configuration. Finally, this work concludes by examining both the annular Bragg resonator and hybrid switch geometries in application to chemical and biological sensing. Both microcavity devices are shown to possess unique characteristics making them ideal for sensitive monitoring of small changes in the refractive index of a chemical or biological analyte.
Health-Related Quality of Life for People with Type 2 Diabetes in Saudi Arabia: A Cross-Sectional Study

Background: The aim of the study was to assess the health-related quality of life and its associated factors among people with type 2 diabetes in Saudi Arabia. Methods: A cross-sectional study was conducted among adults with type 2 diabetes who attended diabetes centres in three major cities in Saudi Arabia in 2017. Participants were interviewed and their medical records were reviewed. The EuroQol 5-Dimension 5-Level was used to assess health-related quality of life, and bootstrap resampling with multiple regression analysis was used to identify its associated factors. Results: A total of 1121 participants were recruited. The mean age was 57.6 ±11.1 years, and the mean utility index of the quality of life was 0.739 ±0.261 (0.795 ±0.197 for males and 0.709 ±0.285 for females) and dropped to 0.566 ±0.339 in the presence of micro- and macro-vascular complications. Among the study participants, 51.0%, 12.3%, and 30.5% had problems with mobility, self-care and usual activity, respectively, while 51.6% and 45.8% had problems with pain-discomfort and anxiety-depression, respectively. Factors associated with low health-related quality of life were low education level, physical activity < 150 minutes per week, long sitting time, anxiety, depression and diabetes complications. Conclusions: Health-related quality of life is low among people with type 2 diabetes in Saudi Arabia, particularly among women and those who had diabetes complications. In order to improve the quality of life, people with type 2 diabetes should maintain a healthy lifestyle, and appropriate interventions should be taken to prevent complications and comorbidities.
Design of high-torque-density double-stator permanent magnet brushless motors

This study proposes and implements an optimal design approach for the double-stator permanent magnet brushless motor. The key is to optimise the split ratio, namely the ratio of the inner-stator outside diameter to the outer-stator outside diameter, of this motor in such a way that the maximum torque density can be achieved. Both finite-element analysis and experimental results are given to verify the validity of the proposed design approach.
Airflow distortion at instrument sites on the RV Ronald H. Brown

Wind speed measurements obtained from research ships are prone to systematic errors caused by the distortion of the air flow around the ship’s hull and superstructure. In this report the air flow around the RV Ronald H. Brown is simulated at two relative wind directions using Computational Fluid Dynamics (CFD). The airflow distortion at three anemometer sites has been quantified for wind speed of 15 ms-1 blowing a) directly over the bows of the ship, and b) from 30o to port of the bow. All anemometers in this study were located in the bows of the ship and experienced moderate flow distortion, with the wind speed being decelerated by 1% to 4% depending on the instrument location and the wind direction. The flow had been displaced vertically by about 0.7 m for the bow-on flow and by about 0.9 m for the flow from 30o to port.
BELSTM: Understanding the Transformer and Bidirectional Long Short-Term Memory for Early Rumor Detection

Early rumor detection has been gaining increasing attention because of tremendous effects caused by fake or unverified information. There are multiple detection methods, but the performance results are not satisfactory when they are applied to early rumor detection. This paper proposes a novel method based on deep learning. Using Transformer as a feature extraction framework, it can better recognize and understand text content. In addition, the problem of gradient vanished of long texts is solved by Bidirectional Long Short-Term Memory (BLSTM). The results of the proposed detection methodology suggest that it has excellent accuracy of 0.925 and other evaluation indicators of excessing 0.9 when using massive news derived from Weibo as a dataset for experiments. The aims of the research are expected to assist users distinguishing the fake news and prevent the rumors from spreading.

The Mucuna bean plant (Mucuna pruriens) is potentially important as a green manure cover crop for villagers in rural tropical communities. Data on physical properties will be needed to carry out engineering design of storage, handling, and processing systems for these beans. Preliminary measurements of physical properties for Mucuna beans were carried out and reported in this study, including single bean size, mass and density, bulk properties, terminal velocity of beans and shells, particle mechanics, and sorption isotherms.
Hybrid CNN-LSTM Model for Answer Identification

User quest for information has led to development of Question Answer (QA) system to provide relevant answers to user questions. The QA task are different than normal NLP tasks as they heavily depend to semantics and context of given data. Retrieving and predicting answers to verity of questions require understanding of question, relevance with context and identifying and retrieving of suitable answers. Deep learning helps to produce impressive performance as it employs deep neural network with automatic feature extraction methods. The paper proposes a hybrid model to identify suitable answer for posed question. The proposes power exploits the power of CNN for extracting features and ability of LSTM for considering long term dependencies and semantic of context and question. Paper provides a comparative analysis on deep learning methods useful for predicting answer with the proposed method . The model is implemented on twenty tasks of babI dataset of Facebook .
Analysis of microstrip discontinuity by edge‐based FEM combined with SOC technique

In this paper, the application of the edge‐based vector finite‐element method combined with the short‐open calibration (SOC) technique to three‐dimensional microstrip discontinuity is presented. This SOC technique is directly accommodated in the FEM algorithm, and is used to truncate the computational domain. The developed FEM algorithm is applied to the modeling of microstrip discontinuities that can be segmented into two distinct sections: a static model of feedlines, and a dynamic model of circuit discontinuity. The FEM is formulated in such a way that the port voltages and currents are explicitly represented through relevant network matrices. The SOC technique is used to remove or separate unwanted parasitic errors brought by the approximation of the impressed voltage source, and also to address the problem of the resulting consistency between different simulations. Truncation of the computational domain by the SOC technique for microstrip circuits makes the iterative solvers for large‐sparse linear matrix equations from the FEM converge much faster than by perfectly matching layers (PMLs). Results for microstrip discontinuities are very well compared with available publications. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 169–174, 2001.
Renin-Angiotensin-Aldosterone System Blockade Strategies and the Risk of Acute Kidney Injury in Septic and Critically Ill Patients

Background: Renin-angiotensin-aldosterone system (RAAS) blockers are widely used for the treatment of hypertension and heart failure, but the usage of angiotensin- converting enzyme inhibitors (ACEi) or angiotensin-receptor blockers (ARB) demands caution due to a potential risk of causing acute kidney injury (AKI). Whether long-term RAAS blockade increases AKI risk and should be withdrawn during critical illness remains inconclusive. This study aimed to investigate the associations between RAAS blockade strategies and AKI incidence in patients admitted to intensive care units (ICUs). Methods: Twenty-four hundred dialysis-free patients admitted to ICUs during December 2015–July 2017 were enrolled. Patients with pre-ICU AKI (n=568) were excluded when examining in-ICU AKI events. Patients using ACEi or ARB for more than 1 month before hospitalization were defined as long-term ACEi/ARB users. ACEi/ARB users were further grouped by ACEi/ARB continuation/withdrawal at ICU admission. Daily urine output and serum creatinine were measured in ICU. The primary outcome was occurrence of AKI within 48 hours after ICU admission, and the secondary outcome was all-cause mortality within 1 year. Results: Totally 1181 (49.2%) AKI cases and 895 (37.3%) deaths within 1 year occurred. ACEis/ARBs were continued for 122 patients and withdrawn for 239 patients. ACEi/ARB users were older and had lower initial estimated glomerular filtration rates (eGFRs). Compared with non-use, long-term ACEi/ARB use [odds ratio (OR) 1.03, 95% confidence interval (CI) 0.85–1.26, p=0.741] and continued ICU use (OR 1.14, 95% CI 0.78–1.68, p=0.491) were not associated with increased AKI risk. ACEi/ARB use was associated with less 1-year mortality. However, compared with withdrawal, continued ACEi/ARB use in ICUs was associated with higher AKI incidence among patients with sepsis (OR 2.89, 95% CI 1.35–6.20, p=0.006). Conclusions: Long-term RAAS blockade was not associated with a higher AKI or mortality incidence during acute illness. Continued ACEi/ARB use in ICUs may increase AKI risk in septic patients. Long-term and continued ACEi/ARB use are recommended, with cautious evaluation at ICU admission.
Fasthpe : a recipe for quick head pose estimation

Estimating the head orientation of a person from a single camera is an important step for human-computer interaction, especially for widely available laptops and hand-held devices. This work aims to track a human face and estimate its orientation in the 6 degrees of freedom from an uncalibrated monocular camera, keeping the user free of any devices or wires. We propose a novel algorithm based on existing computer vision techniques for a real-time (2ms) head pose estimation system, which can start and recover from failure automatically without any previous knowledge of the user’s appearance or location. We demonstrate that this computationally ecient pose estimation system is able to track the continuous roll, yaw, and pitch angles within absolute errors of 3.03, 5.27 and 3.91 degrees respectively. We show that with the tracking of only four face features, it is possible to obtain continuous head orientation measurements in real-time (2ms).
Antimicrobial Synergism between Bacteriophage UBU-SA1 and Oxacillin against Staphylococcus aureus

Introduction: Bacteriophages have been proven to be effective in controlling bacteria and potential as alternatives to antibiotics. Recently, combination treatments using both bacteriophages and antibiotics have been reported to substantially improve antimicrobial activity when compared with their treatments. Objectives: To isolate a lytic bacteriophage specific to Staphylococcus aureus ATCC 25923 and determine antimicrobial activity against S. aureus ATCC 25923 of the isolated bacteriophage and oxacillin when used individually and in co-treatment. Methods: A lytic bacteriophage was isolated from a hospital wastewater sample by enrichment technique. Its host range was examined using the spot test method. The effect of oxacillin on the lytic activity of the bacteriophage was determined. Lastly, the minimal inhibitory concentrations (MICs) of the bacteriophage and oxacillin against S. aureus ATCC 25923 when used individually and in co-treatment were determined using the spot test method. The fractional inhibitory concentration index (FICI) was used to analyze the co-treatment. Results: A bacteriophage, designated bacteriophage UBU-SA1, was isolated. It was found to be highly specific to S. aureus ATCC 25923. Its lytic activity was not inhibited by oxacillin. MICs of bacteriophage UBU-SA1 and oxacillin against S. aureus ATCC 25923, when used alone, were 10 5 PFU/mL and 50 µg/mL, respectively. Co-treatment of bacteriophage UBU-SA1 and oxacillin substantially reduced the MICs of both agents required to inhibit the bacterial host when compared with their treatments. The FICI indicated a synergistic effect between bacteriophage UBU-SA1 and oxacillin against S. aureus ATCC 25923. Conclusion: Bacteriophage UBU-SA1, by itself or in combination with antibiotics, may be useful as a therapeutic agent in controlling S. aureus .
Impact and Energy Analysis of Deformation-Limited Base-Isolated Structure in Shaking Table Test

The deformation of isolation layer in base-isolated building can exceed original design during strong earthquake excitations, which will cause poundings between structure and surrounding retaining wall. Spring limiter installed in base-isolated building can protect the structure. Shaking table test of base-isolated model pounding with spring limiters were performed. The study find the deformation of isolation layer can be effectively reduced by spring limiters, and the deformation of the superstructure will increase slightly. Pounding between structure and spring limiters can arouse high frequency acceleration of building, but had little effect on velocity.Increasing the spring limiters will not change seismic total energy input on the structure, and most of the energy dissipate by the damping. Impact energy dissipation increases with reducing in the gap between structure and spring limiters.
