Experimental Investigation of the Performance of Triangular Vanes on Bed Topography in Straight Rivers. (2020)

Spur dikes are one of the structures used for protection of river banks from erosion and rivers organization. They are usually rectangular and perpendicular to the flow. Unfortunately, the scour development in the tip of those can lead damage to the structure. Furthermore, sedimentation between the spur dikes as well as increasing the flow velocity in the middle of the channel due to the large obstruction, are among the factors that create problems for aquatic life of the river. These problems are minimal in the triangular vanes. The main purpose of this paper is to evaluate the performance of the triangular vanes on bed topography changes in the different flow conditions. For this reason, some tests were carried out at a straight flume for different flow conditions (five Froude numbers of 0.18, 0.20, 0.22, 0.24 and 0.26) by installing series of triangular vanes with space of 4Le (Le is the effective length of structure) at the angle of 30 degrees to the upstream bank. At the end of each test the bed topography was measured by laser distance measurer. The results showed that, the geometric dimension of the scour hole for the rectangular spur dikes was larger than that for the triangular vanes. On average, the length and depth of scour hole for the rectangular spur dikes were 1.3 and 1.5 times higher in comparison to those for triangular vanes, respectively. In addition, the position of the maximum scour depth for the triangular vanes was about 40% farther from the bank than that case of rectangular spur dikes that was an advantage for the triangular vanes.
Circulating Anticoagulants: Physiologic and Pathophysiologic (1983)

Most of the pathophysiologic coagulation inhibitors are actually antibodies to specific clotting factors. The clinical manifestations of the inhibitors are nearly indistinguishable from those of congenital deficiencies of the factors against which they are directed. Thus, the anticoagulation disorder must be identified and understood for effective management.
Retracted: Research and Design of Zigbee-Based Swimming Pool Positioning Anti-Flooding Device (2018)

In the swimming process, swimmers are more common in safety hazards such as drowning due to various factors. A Zigbee-based pool positioning anti-flooding device and corresponding swimming pool management platform are designed to ensure the safety of swimmers. The device is equipped with a hydraulic sensor, an audible and visual alarm and a wireless transmission module. When the swimmer is detected to sneak into the bottom of the water depth of 80CM for more than 20S for sound and light alarm, at the same time in the monitoring room can clearly grasp the specific location of the swimming pool where the swimmer is located, convenient for rescue.
Progress in natural language understanding-An application to lunar geology (1973)

The advent of computer networks such as the ARPA net (see e.g., Ornstein et al.) has significantly increased the opportunity for access by a single researcher to a variety of different computer facilities and data bases, thus raising expectations of a day when it will be a common occurrence rather than an exception that a scientist will casually undertake to use a computer facility located 3000 miles away and whose languages, formats, and conventions are unknown to him. In this foreseeable future, learning and remembering the number of different languages and conventions that such a scientist would have to know will require significant effort---much greater than that now required to learn the conventions of his local computing center (where other users and knowledgeable assistance is readily available). The Lunar Sciences Natural Language Information System (which we will hereafter refer to as LUNAR) is a research prototype of a system to deal with this and other man-machine communication problems by adapting the machine to the conventions of ordinary natural English rather than requiring the man to adapt to the machine.

File Allocation in Distributed Databases with Interaction between Files (1983)

In this paper, we re-examine the file allocation problem. Because of changing technology, the assumptions we use here are different from those of previous researchers. Specifically, the interaction of files during processing of queries is explicitly incorperated into our model and the cost of communication between two sites is dominated by the amount of data transfer and is independent of the receiving and the sending sites. We study the complexity of the file allocation problem using the new model. Unfortunateiy, the problem is NP-hard. We Present an approach to three versions of the problem, thus demonstrating the flexibility of our approach. we further argue that our method provides a practical solution to the problem, because accurate solutions are obtained, the time complexity cf our algorithm is much smaller than existing algorithms, the algorithm is conceptually simple, easy to implement and is adaptive to users ’ changing access patterns.

Practical application of 1588 security (2008)

Version 2 of IEEE 1588 contains an extension to secure the given service of clock synchronization. This article describes a practical implementation of this extension for a clock synchronization network. Pitfalls also relevant to other implementations and important properties are discussed and performance results that cover normal operation and stress tests such as denial of service attacks are presented. Additionally, important concepts for integration of hardware timestamping and transparent clock support are presented, which are necessary to use the full potential in more complicated applications.

A computer-aided multi-train simulator for rail traffic (2007)

This paper presents a multi-train simulator based on traction calculations for rail traffic. The simulator is developed by object-oriented methods and modular structure design and it can mainly provide three functions for users: single-train traction calculation, multi-train simulation and timetable assessment. The architecture of the simulator and multi-train movement model is first discussed in this paper. Two successive trains running on an inter-city railway line are then modeled by the simulator. The simulation results in the case study show that the computer-aided simulator can effectively analyze the sensitivity between train delays and headways.
The effect of different solvents and number of extraction steps on the polyphenol content and antioxidant capacity of basil leaves (Ocimum basilicum L.) extracts (2015)

The objectives of this study were to determine best conditions for the extraction of phenolic compounds from fresh, frozen and lyophilized basil leaves. The acetone mixtures with the highest addition of acetic acid extracted most of the phenolic compounds when fresh and freeze-dried material have been used. The three times procedure was more effective than once shaking procedure in most of the extracts obtained from fresh basil leaves - unlike the extracts derived from frozen material. Surprisingly, there were not any significant differences in the content of phenolics between the two used procedures in the case of lyophilized basil leaves used for extraction. Additionally, the positive correlation between the phenolic compounds content and antioxidant activity of the studied extracts has been noted. It is concluded that the acetone mixtures were more effective than the methanol ones for polyphenol extraction. The number of extraction steps in most of the cases was also a statistically significant factor affecting the yield of phenolic extraction as well as antioxidant potential of basil leaf extracts.
Real-Time Fault Detection and Diagnosis Using Intelligent Monitoring and Supervision Systems (2020)

In monitoring and supervision schemes, fault detection and diagnosis characterize high efficiency and quality production systems. To achieve such properties, these structures are based on techniques that allow detection and diagnosis of failures in real time. Detection signals faults and diagnostics provide the root cause and location. Fault detection is based on signal and process mathematical models, while fault diagnosis is focused on systems theory and process modeling. Monitoring and supervision complement each other in fault management, thus enabling normal and continuous operation. Its application avoids stopping productive processes by early detection of failures and by applying real-time actions to eliminate them, such as predictive and proactive maintenance based on process conditions. The integration of all these methodologies enables intelligent monitoring and supervision systems, enabling real-time fault detection and diagnosis. Their high performance is associated with statistical decision-making techniques, expert systems, artificial neural networks, fuzzy logic and computational procedures, making them efficient and fully autonomous in making decisions in the real-time operation of a production system.
Por qué sigo siendo de izquierda (1997)

Harmine is a beta-carboline alkaloid found in medicinal plant PeganumHarmala, which has served as a folk anticancer medicine. However, clinical applications of harmine were limited by its low pharmacological effects and noticeable neurotoxicity. In this study, we modified harmine to increase the therapeutic efficacy and to decrease the systemic toxicity. Specifically, two tumor targeting harmine derivatives 2DG-Har-01 and MET-Har-02 were synthesized by modifying substituent in position-2, -7 and -9 of harmine ring with two different targeting group2-amino-2-deoxy-D-glucose (2DG) and Methionine (Met), respectively. Their therapeutic efficacy and toxicity were investigated both in vitro and in vivo. Results suggested that the two new harmine derivatives displayed much higher therapeutic effects than non-modified harmine. In particular, MET-Har-02 was more potent than 2DG-Har-01 with promising potential for targeted cancer therapy.
High-throughput biological small-angle X-ray scattering with a robotically loaded capillary cell (2012)

With the rise in popularity of biological small-angle X-ray scattering (BioSAXS) measurements, synchrotron beamlines are confronted with an ever-increasing number of samples from a wide range of solution conditions. To meet these demands, an increasing number of beamlines worldwide have begun to provide automated liquid-handling systems for sample loading. This article presents an automated sample-loading system for BioSAXS beamlines, which combines single-channel disposable-tip pipetting with a vacuum-enclosed temperature-controlled capillary flow cell. The design incorporates an easily changeable capillary to reduce the incidence of X-ray window fouling and cross contamination. Both the robot-control and the data-processing systems are written in Python. The data-processing code, RAW, has been enhanced with several new features to form a user-friendly BioSAXS pipeline for the robot. The flow cell also supports efficient manual loading and sample recovery. An effective rinse protocol for the sample cell is developed and tested. Fluid dynamics within the sample capillary reveals a vortex ring pattern of circulation that redistributes radiation-damaged material. Radiation damage is most severe in the boundary layer near the capillary surface. At typical flow speeds, capillaries below 2 mm in diameter are beginning to enter the Stokes (creeping flow) regime in which mixing due to oscillation is limited. Analysis within this regime shows that single-pass exposure and multiple-pass exposure of a sample plug are functionally the same with regard to exposed volume when plug motion reversal is slow. The robot was tested on three different beamlines at the Cornell High-Energy Synchrotron Source, with a variety of detectors and beam characteristics, and it has been used successfully in several published studies as well as in two introductory short courses on basic BioSAXS methods.
GINGER RHIZOME: A NEW SOURCE OF PROTEOLYTIC ENZYME (1973)

The proteolytic activity of ginger rhizome was studied with bovine serum albumin (BSA), collagen and actomyosin as substrates. A semipurified, powdered enzyme preparation was prepared by buffer extraction of an acetone powder of ginger rhizome and subsequent acetone precipitation of the proteolytic principle from the buffer extract. With 3% BSA as substrate, a relatively high proteolytic activity occurred over a pH range of 4.5–6.0, with an optimum pH of 5.0. The optimum temperature for proteolysis of BSA was 60°C during a 10 min reaction time, with rapid denaturation of the enzyme occurring at 70° C. NaCl in cone up to 10% produced about a 20 and 50% reduction in proteolysis of collagen and BSA, respectively. The ginger protease was protected by dithiothreitol during extraction and reaction, indicating the involvement of −SH groups at the active site. The analyses of soluble peptide amino acids or terminal amino acids suggest that the proteolysis of collagen is many fold greater than that of actomyosin. The combined proteolysis of these two muscle protein fractions by the ginger protease resulted in significantly more tender meat. According to conventional nomenclature, “Zingibain” is the proper name for this proteolytically active principle in Zingiber officinale roscoe or ginger rhizome which is commonly referred to as gingerroot. For meat applications, a possible advantage of zingibain over papain and ficin is the greater proteolysis of collagen in comparison to actomyosin. When compared to reported values for bromelain, zingibain has a higher optimum activity temperature, which is desirable in some applications
Measurement Context Extraction from Text: Discovering Opportunities and Gaps in Earth Science (2017)

We propose Marve, a system for extracting measurement values, units, and related words from natural language text. Marve uses conditional random fields (CRF) to identify measurement values and units, followed by a rule-based system to find related entities, descriptors and modifiers within a sentence. Sentence tokens are represented by an undirected graphical model, and rules are based on part-of-speech and word dependency patterns connecting values and units to contextual words. Marve is unique in its focus on measurement context and early experimentation demonstrates Marve's ability to generate high-precision extractions with strong recall. We also discuss Marve's role in refining measurement requirements for NASA's proposed HyspIRI mission, a hyperspectral infrared imaging satellite that will study the world's ecosystems. In general, our work with HyspIRI demonstrates the value of semantic measurement extractions in characterizing quantitative discussion contained in large corpuses of natural language text. These extractions accelerate broad, cross-cutting research and expose scientists new algorithmic approaches and experimental nuances. They also facilitate identification of scientific opportunities enabled by HyspIRI leading to more efficient scientific investment and research.
Discrete &lt;formula formulatype="inline"&gt;&lt;tex&gt;$H_{2}/H_{\infty}$&lt;/tex&gt; &lt;/formula&gt; Nonlinear Controller Design Based on Fuzzy Region Concept and Takagi&amp;ndash;Sugeno Fuzzy Framework (2006)

The purpose of this paper is to develop a fuzzy controller to stabilize a discrete nonlinear model in which the controller rule is adjustable and it is developed for stabilizing Takagi-Sugeno (T-S) fuzzy models involving lots of plant rules. The design idea is to partition the fuzzy model into several fuzzy regions, and regard each region as a polytopic model. The proposed fuzzy controller is called the T-S fuzzy region controller (TSFRC) where the controller rule has to stabilize all plant rules of the fuzzy region and guarantee the whole fuzzy system is asymptotically stable. The stability analysis is derived from Lyapunov stability criterion in which the robust compensation is considered and is expressed in terms of linear matrix inequalities. Comparing with parallel distributed compensation (PDC) designs, TSFRC is easy to be designed and to be implemented with simple hardware or microcontroller. Even if the controller rules are reduced, TSFRC is able to provide competent performances as well as PDC-based designs
Chapitre II. Putting bohemia on the map (2010)

The title at the head of this essay may seem to go against something I wrote in a book now more than twenty years old, namely that “bohemia cannot be charted, graphed, and counted, because it was never wholly an objective condition” But it fits well with something else I noted there, namely that locating bohemia on a map was a favorite activity of many who spoke about it in the days when both the name and what it described were new. For bohemia’s friends it was bounded by such things as work ...
Empirical Mode Decomposition vs. Wavelet Decomposition for the Extraction of Respiratory Signal From Single-Channel ECG: A Comparison (2013)

The respiratory signal can be accurately evaluated by single-channel electrocardiogram (ECG) processing, as shown in recent literature. Indirect methods to derive the respiratory signal from ECG can benefit from a simultaneous study of both respiratory and cardiac activities. These methods lead to major advantages such as low cost, high efficiency, and continuous noninvasive respiratory monitoring. The aim of this paper is to reconstruct the waveform of the respiratory signal by processing single-channel ECG. To achieve these goals, two techniques of decomposition of the ECG signal into suitable bases of functions are proposed, such as the empirical mode decomposition (EMD) and the wavelet analysis. The results highlight the main differences between them in terms of both theoretical foundations, and performance achieved by applying these algorithms to extract the respiratory waveform shape from single-channel ECG are presented. The results also show that both algorithms are able to reconstruct the respiratory waveform, although the EMD is able to break down the original signal without a preselected basis function, as it is necessary for wavelet decomposition. The EMD outperforms the wavelet approach. Some results on experimental data are presented.
Potential Aquifer Pollution from Nitrate Leaching Following the Plowing of Temporary Grassland (1984)

Abstract An investigation of the amounts and concentrations of nitrate released following the plowing of temporary grassland confirmed that, potentially at least, this practice forms a major source of NO 3 ‐N pollution of aquifers. Direct measurements of changes in profile NO 3 ‐N distributions at two sites show that a total of up to about 100 kg N ha −1 was leached over two winters after fall mineralization following plowing. Solution nitrate concentrations were in excess of the World Health Organization limits for drinking water. The amount of N mineralized was related to the total soil N. The average rate of leaching through the Chalk soils studied in southern England was about 1 m/yr.
