Simple Simulation Model for Manoeuvring Ship Motion of Twin-propeller and Single-Rudder Ships

Twin-propeller and single-rudder ships are frequently used for medium high-speed ships such as container ships and passenger ferries. However, the maneuvering simulation for these ships is not easy because the interaction forces between propellers and rudder become very much complicated. In this paper, the authors have investigated a simple analysis and simulation technique for maneuvering ship motion of twin propeller and rudder ships. For this purpose, captive model tests have been carried out, where the propeller thrusts and rudder normal force as well as ship hull forces are obtained for various parameters including propeller rps and rudder angle. Although the propeller thrusts are slightly different in each other for port and starboard sides and this makes the additional yaw moment, the thrust is assumed to be a single propeller’s one by means of combining the both sided thrusts as if the ship is a single propeller and rudder ship. In this analysis, the propeller diameter is assumed to be √2 times larger and propeller rps 1/√2 times, so that the thrust coefficient KT becomes the average thrust coefficient of twin propellers. This assumption can make very simple and easier since the conventional mathematical model for single propeller and rudder ships can be applied. In order to validate the above method, free-running model tests have been carried out and compared with the simulated results. As the result, it is found that this simple technique becomes very useful for the simulation of twin-propeller and single-rudder ships.
The Impact of Behavioral Topic on Psychological Reactance: Arousal and Freedom Restoration

ABSTRACT Psychological reactance theory (PRT) proposes that the importance of freedom, along with threat to freedom and receiver personality trait, impacts the arousal of psychological reactance and the subsequent freedom restoration. This paper presents a 2 (threat: low vs. high) × 3 (source: the CDC, victim of the health issue vs. AI) × 2 (health topic: college drinking vs. STD) between-subjects experiment (N = 765) to test the potential effects of topic and source legitimacy on reactance. Results showed that behavioral topic influenced the magnitude of psychological reactance and forms of freedom restoration simultaneously. Theoretical contributions, implications, and limitations are discussed.
Online monitoring and prediction of complex time series events from nonstationary time series data

OF THE DISSERTATION Online Monitoring and Prediction of Complex Time Series Events From Nonstationary Time Series Data by Shouyi Wang Dissertation Director: Wanpracha Art Chaovalitwongse Much of the world’s supply of data is in the form of time series. In the last decade, there has been an explosion of interest in time series data mining. Time series prediction has been widely used in engineering, economy, industrial manufacturing, finance, management and many other fields. Many new algorithms have been developed to classify, cluster, segment, index, discover rules, and detect anomalies/novelties in time series. However, traditional time series analysis methods are limited by the requirement of stationarity of the time series and normality and independence of the residuals. Because they attempt to characterize and predict all time series observations, traditional time series analysis methods are unable to identify complex (nonperiodic, nonlinear, irregular, and chaotic) characteristics. As a result, the prediction of multivariate noisy time series (such as physiological signals) is still very challenging due to high noise, non-stationarity, and non-linearity. The objective of this research is to develop new reliable frameworks for analyzing multivariate noisy time series, and to apply the framework to online monitor noisy time series and predict critical events online. In particular, this research made an extensive study on one important form of multivariate time series: electroencephalography (EEG) data, based on which two new online monitoring and prediction frameworks for multivariate time series were introduced and evaluated. The new online monitoring and
RETRACTED ARTICLE: Perceptions of radicalisation in mental health care and the security domain: roles, responsibilities, and collaboration

ABSTRACT This study investigates how perceptions of radicalisation and co-occurring mental health issues differ between mental health care and the security domain, and how these perceptions affect intersectoral collaboration. It is generally thought that intersectoral collaboration is a useful strategy for preventing radicalisation and terrorism, especially when it concerns radicalised persons with mental health issues. It is not clear, however, what perceptions professionals have of radicalisation and collaboration with other disciplines. Data was obtained from focus groups and individual interviews with practitioners and trainers from mental health care and the security domain in the Netherlands. The results show a lack of knowledge about radicalisation in mental health care, whereas in the security domain, there is little understanding of mental health issues. This leads to a mad-bad dichotomy which has a negative effect on collaboration and risk management. Improvement of the intersectoral collaboration by cross-domain familiarization, and strengthening of trust and mutual understanding, should begin with the basic training of professionals in both domains. The Care and Safety Houses in the Netherlands offer a sound base for intersectoral collaboration. Future professionals from different domains ought to be familiarized with each other’s possibilities, limitations, tasks, and roles.
Testing Strategy with Multiple Performance Measures: Evidence from a Balanced Scorecard at Store24

The Campbell, Datar, Kulp, and Narayanan (2015; hereafter, CDKN) study empirically investigates how the quality of a firm's business strategy can be tested and validated using statistical analysis of the firm's internal performance measurement system. Using data from the balanced scorecard of a convenience store chain, their study provides empirical evidence that the company's internal performance measures reveal timely information about problems with the strategy and can help identify where and why the strategy failed. In this brief discussion of the study, I first summarize the major strengths of their study, then discuss my concerns and comments, and finally point out some potential extensions. In summary, CDKN's study is important in that it makes significant contributions to several streams of literature. CDKN have inspired follow-up studies on the use of performance measurement systems to evaluate strategy and the testing of business models, and has opened up exciting opportunities for future research.
Exploring the Asymmetric Characteristics of a Double Gate MOSFET with Linearly Graded Binary Metal Alloy Gate Electrode for Enhanced Performance

ABSTRACT The present boon in the research field of nanoscale device physics is attributed to a large extent by the development of non-conventional multiple gate MOS devices due to increased device packing density and enhanced gate electrostatic control over the channel. In this work, we have investigated the attributes of an asymmetric Double Gate metal oxide semiconductor field effect transistor (MOSFET) incorporating the novel theory of work function engineering by the continuous horizontal variation of mole fraction in a binary metal alloy gate in a fully depleted Double Gate MOSFET. A two-dimensional analytical modeling of this Linearly Graded Asymmetric Double Gate MOSFET structure has been done to formulate a simplified expression for short channel threshold voltage, and an overall performance analysis of our proposed device has been presented to establish the superiority of our proposed structure in terms of superior short channel effect mitigation and a significant reduction in threshold voltage. The results obtained from our analytical analysis are found to be in good agreement with the simulation results, thereby, establishing the accuracy of our model.
International Journal of Emerging Electric Power Systems Multi-Objective Day-Ahead Real Power Market Clearing with Voltage Dependent Load Models

In this paper, we investigate the influence of voltage dependent load models on day ahead real power market clearing (DA-RPMC). The investigations clearly bring out the unsuitability of conventional single objectives such as production cost minimization (PCM) (or social welfare maximization (SWM)), due to reduction of load served. Hence, the multi-objective optimization is essential in this context. The paper proposes several objectives such as production cost minimization (PCM) (or social welfare maximization (SWM)), load served maximization (LSM), and Voltage Stability Enhancement Index (VSEI); which can be judiciously combined as per the needs of the operating condition. Multi-objective Strength Pareto Evolutionary Algorithm (SPEA) has been used to solve the DA-RPMC problem. The effectiveness of the proposed approach is tested on IEEE 30 bus system and the detailed simulation studies have been carried out by considering different operating conditions with voltage dependent load modeling.
Perioperative Continuous Noninvasive Cardiac Output Monitoring in Cardiac Surgery Patients by a Novel Capnodynamic Method.

OBJECTIVES To test the clinical performance of a novel continuous noninvasive cardiac output (CO) monitoring based on expired carbon dioxide kinetics in cardiac surgery patients. DESIGN A prospective feasibility pragmatic clinical study. SETTING A single-center, large community hospital. PARTICIPANTS Thirty-two patients undergoing cardiac surgery were studied during the intraoperative (before cardiopulmonary bypass) and postoperative (in the intensive care unit before extubation) periods. INTERVENTIONS CO was measured simultaneously by the continuous capnodynamic method and by transpulmonary thermodilution during changes in the patient's hemodynamic and/or respiratory conditions. MEASUREMENTS AND MAIN RESULTS The current recommended comparative statistics for CO measurement methods were analyzed, including bias, precision, and percentage error obtained from Bland-Altman analysis, and concordance between methods obtained from the four-quadrant plot analysis to evaluate the trending ability. Bias ± limits of agreement and percentage error were -0.6 (-1.9 to +0.8; 95% CI of 3.73-5.25) L/min and 31% (n = 147 measurements) for the intraoperative period, -0.8 (-2.4 to +0.9; 95% CI of 3.03-5.21) L/min and 41% (n = 66) for the postoperative period, and -0.6 (-2.1 to +0.8; 95% CI of 3.74-5.00) L/min and 34% (n = 213) for the pooled data. The trending analysis obtained a concordance of 82% (n = 65) for the intraoperative and 71% (n = 24) for the early postoperative periods. Aggregation of both data sets gave a concordance of 79% (n = 89). CONCLUSIONS The continuous capnodynamic method was reliable and in good agreement with the reference method, and had an accuracy and trending ability good enough to make it a possible future alternative for hemodynamic monitoring in the studied population of elective adult cardiac surgery patients.
Examination of a Response–Effect Compatibility Task With Continuous Mouse Movements: Free- Versus Forced-Choice Tasks and Sequential Modulations

According to ideomotor theory, we select actions by recalling and anticipating their sensory consequences, that is, their action effects. Compelling evidence for this theory comes from response–effect compatibility (REC) experiments, in which a response produces an effect with which it is either compatible or incompatible. For example, pressing a left/right response key is faster if it is predictably followed by an action effect on the same, compatible side compared with the other, incompatible side, even though the effect itself appears only after response time is measured. Recent studies investigated this effect with continuous responses (i.e., computer mouse movements) and reported an REC effect in a forced-choice but not in a free-choice task. From the keypressing literature, the opposite result pattern or no differences would have been expected. To clarify this issue, we report 3 experiments with mouse movement responses. Experiment 1 used a simpler scenario than in prior studies and found a similar result: The REC effect was evident in a forced- but not in a free-choice task. Also, sequential modulations of the REC effect were exploratorily analyzed and replicated with higher power in Experiment 2. However, Experiment 3 demonstrated that at least part of the REC effect with mouse movements can be attributed to stimulus–response compatibility (SRC), with a much smaller compatibility effect evident with a procedure for which SRC was reduced. We conclude that a sequentially modulated compatibility effect can be observed with mouse movements, but previous studies may have underestimated the contribution from SRC. The results are also discussed in terms of why the compatibility effect was observed in forced- but not free-choice tasks with mouse movement responses.
Large Eddy Simulation of a Controlled-Diffusion Cascade Blade at Varying Flow Inlet Angles

A Controlled Diffusion cascade stator blade has been studied numerically using Large Eddy Simulation (LES). The aim of the study is to assess the performance of Large Eddy Simulation in predicting flow features on a highly-loaded blade, including leading-edge separation, transition and turbulent reattachment, particularly at off-design conditions. The need for LES to be performed on high resolution grids is highlighted by preliminary simulations on a mesh typically used in Reynolds-Averaged approaches. On a fine grid, the unsteady flow features captured by time-dependent simulation yield an improvement in surface pressure distributions and boundary layer profiles, although some weaknesses are apparent in the prediction of pressure-side boundary layer properties and wake profiles. The computed loss coefficients show potential for LES to be used to obtain loss-loop data over a wide range of incidence angles. © 2009 ASME
Experimental Study on Vibration and Sound Radiation Characteristics of New Type of Damped Wheel with Web-mounted Noise Shielded

The wheel/rail noise is the main component of the urban rail traffic noise. Low noise wheel is a key measure for reducing noise of train. A new type of web-mounted noise shielded and vibration damped device is designed and installed on a straight web metro wheel. Acoustic experiments of this new type damped wheels are carried out in a semi-anechoic chamber. Using a force-hammer and a 25 mm diameter steel ball to hit the wheel as the excitations, the frequency response and the acoustic radiation characteristics of the damped wheel can be obtained through the tests. The experimental results show that the damping ratio of the damped wheel increases significantly. The modal damping ratio increases by more than 10 times above 800 Hz, compared to the original wheel. The amplitude of the frequency response function reduces significantly in the frequency range of 0-6 400 Hz. Under the radial and axial excitations, the sound energy level of the damped wheel decreases by 12.4-13.5 dB and 12.4-14.7 dB, respectively. In some significant frequency bands, the sound energy level of the damped wheel decreases about 15dB.
Time Dependent Contamination Source Determination: A Network Subdomain Approach for Very Large Water Networks

This paper presents an approach for identifying contamination sources in very large municipal water networks. The vulnerability of municipal drinking water networks to intentional and accidental contaminations requires investigation of alternative protection measures. If a contamination occurs, it is important to identify both the time and location of the contamination source. A dynamic optimization approach for estimating contamination sources was previously presented. The approach developed an origin tracking algorithm that reformulated the partial dieren tial pipe expressions, removing the need to discretize in space. Although this allowed for ecien t solutions using a direct simultaneous technique for a network of approximately 500 nodes, the approach does not scale indenitely to very large networks. This current paper handles very large water networks by performing the optimization on a smaller, subdomain of the entire network. This approach considers the hydraulics and sensor measurements for the entire network, but formulates the dynamic optimization problem for a subset of the network nodes. A subdomain approach is introduced, forming a geographic window around the rst sensor to detect contaminant. Numerical results indicate that this subdomain approach is eectiv e at identifying contamination sources. Furthermore, since the required subdomain size is not dependent on the size of the entire network, this approach scales to very large municipal water networks.
THE DESIGN OF ATRIAS 1.0 A UNIQUE MONOPOD, HOPPING ROBOT ∗

ATRIAS 1.0 is a spring-legged, monopod robot designed and built as a prototype towards a human-scale 3D biped. The monopod has to meet certain requirements concerning locomotion dynamics and energy efficiency to meet the goal of a biped that can autonomously walk and run efficiently and robustly outdoors, untethered over realistic (non-ideal) terrain. The design of ATRIAS 1.0 includes adequate control authority for robust locomotion as well as incorporating the idea of passive dynamics for high energy economy. Towards this effort, the passive dynamics of ATRIAS 1.0 are designed to match the key features of the Spring Loaded Inverted Pendulu mm odel: a massless leg, mass centered at the hip joint, and a series spring between the ground and the mass at the hip joint. In this paper the authors discuss the key features of this unique robot design.

Influences of a Classroom Setting on Students’ Artistic Processes

Abstract:This study uses Mace and Ward’s model of the artistic process as a theoretical framework to examine the art-making processes of students enrolled in an Advanced Placement (AP) art class in a public high school. Previous scholarship about the artistic process is grounded in the experience of professional artists and has not sufficiently attended to whether and how the artistic process of students in K–12 classroom contexts mirrors the work of artists outside school contexts. Data from classroom observations and interviews of AP art students suggests students’ processes were closely aligned to Mace and Ward’s descriptive model of the art-making process. The data also suggest that two major factors influenced students’ artistic process in school contexts: the influence of the teacher and working in a shared classroom space.
Regulation of Mannitol Metabolism in Enterococcus faecalis and Association with parEF0409 Toxin-Antitoxin Locus Function

Enterococcus faecalis is both a common member of the human gut microbiota and an opportunistic pathogen. Its evolutionary success is partially due to its metabolic flexibility, in particular its ability to import and metabolize a wide variety of sugars. ABSTRACT The parEF0409 type I toxin-antitoxin locus is situated between genes for two paralogous mannitol family phosphoenolpyruvate phosphotransferase systems (PTSs). In order to address the possibility that parEF0409 function was associated with sugar metabolism, genetic and phenotypic analyses were performed on the flanking genes. It was found that the genes were transcribed as two operons: the downstream operon essential for mannitol transport and metabolism and the upstream operon performing a regulatory function. In addition to genes for the PTS components, the upstream operon harbors a gene similar to mtlR, the key regulator of mannitol metabolism in other Gram-positive bacteria. We confirmed that this gene is essential for the regulation of the downstream operon and identified putative phosphorylation sites required for carbon catabolite repression and mannitol-specific regulation. Genomic comparisons revealed that this dual-operon organization of mannitol utilization genes is uncommon in enterococci and that the association with a toxin-antitoxin system is unique to Enterococcus faecalis. Finally, we consider possible links between parEF0409 function and mannitol utilization. IMPORTANCE Enterococcus faecalis is both a common member of the human gut microbiota and an opportunistic pathogen. Its evolutionary success is partially due to its metabolic flexibility, in particular its ability to import and metabolize a wide variety of sugars. While a large number of phosphoenolpyruvate phosphotransferase sugar transport systems have been identified in the E. faecalis genome bioinformatically, the specificity and regulation of most of these systems remain undetermined. Here, we characterize a complex system of two operons flanking a type I toxin-antitoxin system required for the transport and metabolism of the common dietary sugar mannitol. We also determine the phylogenetic distribution of mannitol utilization genes in the enterococcal genus and discuss the significance of the association with toxin-antitoxin systems.
