Interaction of In-Line and Cross-Flow Vortex Induced Vibrations in Risers

VIV in pipeline and risers has been studied through numerous experimental investigations using simplified model set-up, consisting of spring mounted rigid cylinders. Models have been constructed to allow in-line, cross-flow, or both in-line and cross-flow motions. Comparison of the model results shows overall agreement, although distinct differences exist between the individual model test series. Different explanation models have been established to try to improve the consistency, however, seldom definitive conclusions have been reached. The present paper presents the use of CFD to document the importance of the interaction of in-line and cross-flow motions on VIV response. 2D numerical tests have been performed using NS3 (DHI-CFD code) for a model undergoing in-line, cross-flow, combined in-line and cross-flow, and cross-flow in combination with forced in-line motions. The paper compares the results with some recent model tests and quantifies the significance of interaction.Copyright © 2002 by ASME
Securing wireless localization against signal strength attacks

OF THE DISSERTATION Securing Wireless Localization against Signal Strength Attacks by Yingying Chen Dissertation Director: Prof. Richard P. Martin and Prof. Wa de Trappe Accurately positioning nodes in wireless and sensor networ ks is important because the location of devices and sensors is a critical input to many higher -level applications. However, the localization infrastructure can be subjected to non-crypt ographic attacks, such as signal attenuation and amplification, that can not be addressed by tradit ional security services. This thesis aims to provide secure and accurate location information in wireless and sensor networks by characterizing the response of localization algorithms to at acks, detecting attacks, localizing adversaries, and additionally, improving localization pe rformance. First we studied the robustness of localization algorithms to ignal strength attacks. We found the performance of localization algorithms degrades significantly under attacks when signals are attenuated or amplified by an adversary. We then f ormulated a theoretical foundation for the attack detection problem using statistical sig nificance testing. We proposed attack detection schemes for two broad localization approaches: s ignal strength and multilateration. We found that different localization systems all contain si milar attack detection capabilities. Next, we examined the applicability of localization method s to localize adversaries participating in identity-based spoofing attacks. We proposed a spoofin g detector for wireless spoofing that utilizes K-means cluster analysis. We integrated our K -means attack detector into a realtime indoor localization system, which is capable of locali zing the positions of attackers. Our
Counting, Computing, and the Representation of Numbers

How easy it is to manipulate numbers depends in part on how they are represented visually. In this paper several ancient systems for representing numbers are compared with the Arabic system, which is used throughout the world today. It is suggested that the Arabic system is a superior vehicle for computing, largely because of the compactness and extensibility of its notation, and that these features have been bought at the cost of greater abstractness. Numbers in the Arabic system bear a less obvious relationship to the quantities they represent than do numbers in many earlier systems. Moreover, the elementary arithmetic operations of addition and subtraction are also more abstract; in some of the earlier systems the addition of two numbers is similar in an obvious way to the addition of two sets of objects, and the correspondence between subtraction with numbers and the subtraction of one set of objects from another is also relatively direct. The greater abstractness of the Arabic system may make it somewhat more difficult to learn and may obscure the basis for such elementary arithmetic operations as carrying and borrowing. The power of the system lies in the fact that once it has been learned, it is the most efficient of any system yet developed for representing and manipulating quantities of all magnitudes.
Association between APOE Genotype with Body Composition and Cardiovascular Disease Risk Markers Is Modulated by BMI in Healthy Adults: Findings from the BODYCON Study

Body mass index (BMI) has been suggested to play an important role in the relationship between the APOLIPOPROTEIN (APO)E genotype and cardiovascular disease (CVD) risk. Using data from the BODYCON cross-sectional study (n = 360 adults) we assessed the association between body composition and CVD risk markers according to APOE genotype, with examination of the role of BMI. In this study cohort, the APOE2/E3 group had lower fasting blood lipids than APOE4 carriers and APOE3/E3 group (p ≤ 0.01). After stratifying the group according to BMI, APOE4 carriers in the normal BMI subgroup had a higher lean mass compared with the APOE3/E3 group (p = 0.02) whereas in the overweight/obese subgroup, the android to gynoid percentage fat ratio was lower in APOE4 carriers than APOE3/E3 group (p = 0.04). Fasting lipid concentrations were only different between the APOE2/E3 and other genotype groups within the normal weight BMI subgroup (p ≤ 0.04). This finding was associated with a lower dietary fibre and a higher trans-fat intake compared with APOE4 carriers, and a lower carbohydrate intake relative to the APOE3/E3 group. Our results confirm previous reports that BMI modulates the effect of APOE on CVD risk markers and suggest novel interactions on body composition, with diet a potential modulator of this relationship.
Development of an Analytical Model to Predict the Field Permeability of Asphalt Pavements

Measurement of the field permeability of asphalt pavement is affected by three-dimensional flow, saturation, and other field boundary conditions. Therefore, field permeability testing is generally avoided for compaction quality control, mix evaluation, and evaluation of moisture intrusion or damage of asphalt pavements. Instead, laboratory permeability is used for asphalt mix (compaction) evaluation. Because most transportation agencies and paving contractors collect field cores for compaction and mix quality evaluation, an analytical model to predict field permeability can be useful in the study of the hydraulic conductivity of field pavements. This study used an analytical model to determine the field permeability of asphalt pavement by using laboratory tests for permeability and permeable pores of cores. Permeability and the permeable porosity of two sizes of asphalt cores were determined in the laboratory with a falling head permeameter that was modified with a salt concentration–measuring meter. The parameters were then used in the analytical model to predict field permeability. The predicted values from the model were found to compare reasonably well with the full-scale field permeability values. The results of the analytical model were compared with the results from existing models, and the developed analytical model showed an improvement over the existing models. The model can be a useful tool in the study of the hydraulic behavior of asphalt.
A GENETIC ALGORITHM FOR THE ALLOCATION OF DANGEROUS GOODS CONTAINERS IN A STORAGE YARD FOR FREIGHT VILLAGES AND DRY PORTS

Increased trade volume between the countries and the resulting increase in container scheduling causes both space allocation problems and traffic congestion at ports, storage yards and terminals, finally leading to occupational accidents. Although there are various studies conducted on containers for non-dangerous goods and handling of them in storage yards, the number of studies on the allocation of dangerous goods containers is limited. Especially the recent explosion at the Tianjin Industrial Port, which was considered to be originated from dangerous goods, highlighted that handling and storage of dangerous goods at the yards must be carried out with more care and attention. This study deals with the optimization of space allocation for dangerous goods containers in the yards for freight villages, dry port and space efficiency for storage yards with limited space. During the analysis, the requirements specified in the segregation table for dangerous goods are taken into account.
The Evolving Mind

Last year saw the publication of two major studies on the evolution of the human mind, Human Evolution, Language and Mind by William Noble and Iain Davidson, and The Prehistory of the Mind by Steven Mithen. Both draw on a number of disciplines including archaeology, psychology, philosophy and animal ethology, but their resulting scenarios of human development differ in several important respects. The question of mind is central to our understanding of the origin of humanness. As Noble and Davidson put it, ‘the mark of modern human behaviour is its self-consciousness, its “mindedness”’. They trace the origin of this behaviour back no further than 100,000 years ago. In Noble and Davidson's view, the behaviours of the ancestors of humans were similar in crucial respects to those of modern non-human primates. Mithen, on the other hand, ‘cannot accept … that language did not appear in a gradual fashion’. Mithen proposes a series of distinct intelligences, and puts forward a modular theory of the evolution of the human mind. In the following pages we present the issues in the form of a debate, inviting each of the three authors to review each other's books and then offering them the opportunity to defend their alternative standpoints. We begin with Mithen's review of Noble and Davidson, then Noble and Davidson's review of Mithen, and finish with their respective replies to the comments and criticisms which have been raised.
Construing the Textual Features , Discourse Practice and the Socio-Cultural Practice of a Wardah Renew You Series Advertisement : A Critical Discourse Analysis

| ABSTRACT This study reports the textual features, discourse practice, and socio-cultural practice in the Wardah Renew You Series advertisement. The objectives of this study are to analyze the textual features, the discourse practice and the socio-cultural practice used in the Wardah Renew You Series advertisement. This study used the descriptive qualitative method. The data were collected from the Wardah Renew You Series advertisement uploaded on the Wardah Beauty Malaysia YouTube channel. The data of this study are phrases and clauses representing the textual features, discourse practice and social-cultural practice. In this study, the writers used Fairclough's three-dimensional models to analyze the data of Critical Discourse Analysis (CDA). The textual features found in the Wardah Renew You Series advertisement are the use of the pronoun 'your', the use of the conjunction 'and', and the use of specific vocabulary. The use of specific vocabulary in this advertisement is a positive adjective. In the discourse practice, the producer of the advertisement is Wardah, and the main target of the advertisement is women aged 25 years and over. In social-cultural practice, there are three levels, namely situational, institutional, and social. On a situational level, the Wardah Renew You Series advertisement was launched along with the emergence of a new beauty campaign carried by Wardah, namely "Feel The New You". Moreover, Wardah also introduced Fenita Arie as the new brand ambassador. This advertisement is not associated with any institution. For the social level, the Wardah Renew You Series advertisement uses words that can influence and invite people, especially women aged 25 years and over, to be confident in their beauty and not worry about premature aging.
Experimental and theoretical study of the oblique impact of a tennis ball with a racket

The normal and the oblique impact of a tennis ball with a racket has been studied. An accurate setup has been built in order to provide consistent initial conditions for the impacts. Experiments have been done for a wide range of impact angles and initial velocities. The motion of the ball before, during and after the impact has been recorded using a high-speed camera with 10,000 frames per second. The impact has been divided into two phases, compression and restitution. An expression for the contact force has been provided. The coefficient of restitution and effective coefficient of friction have been analyzed experimentally. For low impact velocities, the coefficient of restitution is constant at different impact angles. The effective coefficient of friction changes as a function of the impact angle. The contact force expression has been determined for the compression and the restitution phases using the experimental data from normal impact experiments. The simulation and experimental results are compared and verified for the normal and the oblique impacts.
Price discovery and gains from trade in asset markets with insider trading

The present study contributes to the ongoing debate on possible costs and benefits of insider trading. We present a novel call auction model with insider information. Our model predicts that more insider information improves informational efficiency of prices, but this comes at the expense of reduced gains from trade. Testing these hypotheses in the lab, we find that insider information increases informational efficiency of call auction prices but does not decrease the realized gains from trade. We further find that the call auction does not perform worse than the continuous double auction. In fact, when the probability of insider information is high, the call auction has the most informative prices and highest realized gains from trade. Our experiment provides new evidence, from markets with very asymmetrically dispersed information, that lends support to the decision by many stock exchanges to use call auctions when information asymmetries are severe and the need for accurate prices is large, e.g. at the open or close of the trading day.
Clinical implementation and scientific development of photodynamic therapy in Russia in 2010-2020

In recent years, the development of methods of photodynamic therapy (PDT) and photodynamic photodiagnostics (PD) in Russia is characterized by an intensive rise, steadily growing interest of specialists from various medical specialties in the method of specialists from various medical specialties, an increase in the level of equipment number of hospitals with the necessary equipment for performing PD and PDT, the and the emergence of new photosensitizers on the pharmaceutical market, and an increasing increase in the level of patients’ confidence in these methods. This study analyzes the dynamics of the development of the clinical application and scientific developments of PD and PDT over the past decade in Russia in terms of the volume of public procurement of photosensitizers, as well as the activity of research work in the field of PD and PDT, the number of candidate and doctoral dissertations theses on this topic and the number of scientific publications in the RSCI. 688 contracts for the supply of photosensitizers for clinical use were analyzed. The analysis showed a stable annual growth in the volume of public procurement of photosensitizers, an increase in the number of subjects of the Russian Federation and clinical centers that purchase photosensitizers through the portal www.zakupki. gov.ru. From 2014 to 2020, the total volume of public procurement of all photosensitizers increased by 8 times (from 36.42 million rubles (3.58 thousand packages) to 307.37 million rubles (18.99 thousand packages)). The annual increase in the volume of public procurement in numerical terms over the previous 6 years ranged from 9.4% to 63.2% in different years. The main share of state purchases of photosensitizers falls on Moscow and St. Petersburg, h. However, in recent years there has been a noticeable trend towards an increase in sales of photosensitizers in the regions. Thus, in recent years, the share of purchases of photosensitizers in the constituent entities of the Russian Federation with a population of less than 1 million people has significantly increased (from 2.9% of the total number of purchases in 2014 to 25.3% in 2020). Also, in recent years, there has been a significant increase in the activity of research work activity in the field of PD and PDT. The number of defended candidate and doctoral dissertations theses defended in the field of PD and PDT photodynamic therapy and fluorescent diagnostics has been steadily high in recent years and, in some scientific specialties, reaches 2-3% of the total number of defended dissertations theses defended in these specialties. The increase in the total number of publications over 10 years according to the RSCI was 224% (from 218 publications in 2014 to 489 publications in 2019), according to the RSCI. The results obtained confirm the growing demand for photosensitizers for photodynamic therapy and fluorescence diagnostics in clinical practice, the expansion of the geography of the use of methods, as well and the stable interest in this topic in the research environment.
Relationships among quality management, IS use and organizational performance in the health care and non-health care setting

In this research, we investigate the relationships between organizational adoption and extent of use of Quality Management (QM) programmes and Information Systems (IS) in two somewhat different organizational settings--health care and non-health care. Specifically, we contend that organizations from the two settings may vary considerably in what we term QM Maturity. Some organizations appear to adopt QM only superficially, while others move far more fully into QM. We use the term QM Maturity to describe organizations that have adopted QM programmes more fully and in 'better' ways qualitatively. Are there differences in the paths which health care and non-health care organizations have used in approaching and implementing QM? In this research, we contend that QM Mature organizations will be characterized by perceptions that the culture is different in ways that are supportive of QM. Moreover, we argue that the higher QM Maturity organizations will approach IS implementation in more mature, qualitatively better ways. In turn, we expect QM Maturity and more mature IS adoption to lead to perceptions by those in the organization that both organizational performance and service quality are better. Where there are differences between health care and non-health care organizations, these areas could be impacted upon as well. Our exploratory research provides support for these ideas and suggests that there may, in fact, be differences in the two settings.
On the design of high-voltage analog front-end circuits for capacitive micromachined ultrasonic transducers (CMUT)

In ultrasound imaging, capacitive micromachined ultrasonic transducer (CMUT) technology has become a promising alternative to conventional piezoelectric-based technology. This work focuses on various aspects of CMUT-based imaging technologies. In the context of CMUT design and integration with associated electronics, flexible and reliable CMUT models that can be seamlessly simulated with the read-out circuits and provide insights in the system-level performance are of great importance. This work proposes a generic Verilog-AMS model for CMUT sensors that takes into account the non-linearities, dynamic behavior and harmonic resonances of the CMUT. This model is able to provide reliable estimations of the pull-in voltage as well as the resonance frequency and the spring softening effect. To improve the signal-to-noise ratio (SNR), integrating the CMUT transducer with the front-end electronics is critical. Design and implementation of a comprehensive analog front-end system in a 0.8 μm high-voltage CMOS technology which includes high-voltage and fast-switching transmitters as well as low-power variable-gain receivers is presented. Co-simulation of the front-end electronics and the CMUT model demonstrates full system functionality.
Enhancing Pre-service Physics Teachers' Higher-Order Thinking Skills Through STEM-PjBL Model

This study aimed to determine the higher-order thinking skills of pre-service teachers through STEM-PjBL Model. The research method used was a quasi-experimental with one group pretest-posttest design. The N-Gain results mention the N-gain in both experimental and control classes that the physics learning process through the STEM-PjBL Model is 21% higher in improving higher-order thinking skills than Direct Learning. Improvement of students' ability to solve HOTS categorical questions in the experimental group taught by applying STEM-PjBL Model scored N-Gain 75% or 0.75, which increases the high category. In comparison, the control group led by applying the Direct Learning model achieved 54% or 0.54, meaning a moderate increase in categories. The results showed that learning using STEM-PjBL Model could improve higher-order thinking skills more than Direct Instruction Learning. The implications of this research include: gaining new knowledge that can be used as a pre-service teacher’, adding insight regarding STEM-PjBL Model that can be used to grow students' science process skills, assisting schools in improving the quality of students, and the quality of the physics learning process in schools.
Vigor de sementes de girassol pela análise computadorizada de plântulas Sunflower seed vigor determined by computerized seedling analysis

The Seed Vigor Imaging System (SVIS™) has stood out for being both fast and efficient to evaluate the physiological potential of seeds of various species. The test evaluates the vigor of seeds by means of parameters related to seedlings growth and uniformity which are calculated from the processing of digital images of the germination test. The objective of this study was to verify the accuracy of the computerized system for seedling image evaluation for the determination of sunflower seed vigor. Six recently harvested sunflower seed lots (cultivar Helio 251) were submitted to the germination, emergence, accelerated aging, tetrazolium, and sanitary tests. The (SVIS™) supplied reference data concerning vigor index, seedling uniformity, growth, and length for seedlings scanned 2 and 3 days after the start of the test. The six lot seeds were evaluated at harvest and after four months of storage under conventional conditions (25 ± 2 °C). The results of computerized analysis of images of seedling resulting from a germination test are not compatible with the results of the tests used in this experiment to evaluate sunflower seed physiological quality.
Simple compensation for lateral misalignments in resonant inductive coupling links

This Letter describes a simple compensation method to reduce the transfer efficiency variation in a resonant inductive coupling (RIC) wireless power transfer link subject to lateral misalignment. The technique is based on impedance matching an RIC link such that the link operates at either over-coupling or critical coupling within the extents of lateral misalignment. Applying the method in a test scenario led to a reduction in the range of obtained transfer efficiency values, from 45% of peak value in a conventional arrangement, to 5%. The proposed method has a potential for application in the design of free-positioning planar wireless chargers.
