Application of a radial basis function neural network to sensor design

One of the important tasks in sensor design is the development of a model for a sensing phenomena. Artificial neural networks are ideal for such a task because of their capability for representation of the mapping functions describing the processes and phenomena which are mathematically difficult or even intractable. We examined a radial basis function (RBF) neural network for modeling of acoustical properties of colloidal TiO2 slurry. The colloidal slurry is a very complex multiphase medium. The RBF network with a set of local Gaussian functions was trained using the data from the earlier developed physical model of TiO2 slurry. Next the TiO2 neural model was used for a prediction of the TiO2 particle size distribution. The resulting prediction accuracies of the RBF network were 99.8% for the data used in the training process and 88% for the data not used in the training. Compared to other available techniques neural networks can offer an effective and time efficient approach for the modeling of complex materials.
Frequency and pattern reconfigurable Yagi patch antenna

This work describes the use of switched slits and slots to reconfigure the operating frequency and the radiation pattern of a Yagi patch antenna. The Yagi patch antenna is fabricated on the top side of a grounded substrate and is fed by a coaxial probe. By using switches to reconfigure the silts etched on the driven patch, the antenna can operate at two frequencies of 8.175 and 9.31 GHz. By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Three of them operate at the higher frequency and two of them at the lower one. The main beams of these models point to different directions in the E‐plane. Simulated and measured results are given and they are in good agreement. The antenna can be used in radar, satellite communications, etc. © 2008 Wiley Periodicals, Inc.

An empirical study of the benefits of construction partnering in Hong Kong

Many construction companies have adopted partnering in their construction projects over the past 10–15 years due to favourable project outcomes achieved. Its use in construction projects has been increasing rapidly as its benefits become more apparent and pervasive. This paper reviews the partnering literature within the construction field and tries to portray the comprehensive picture of benefits for the partnering practice. Through partnering and the active involvement of all key project parties, the project is more likely to be completed within budget, on time, and with the least number of conflicts, claims and work defects. Also, this paper reports upon the findings of a questionnaire survey of partnering benefits in Hong Kong. Seventy‐eight project participants completed a questionnaire to indicate the relative importance of partnering benefits. The perceived benefits were measured and ranked from the perspectives of the client, contractor and consultant for cross‐comparison. The results revealed that ‘Improved relationship amongst project participants’, ‘Improved communication amongst project participants’ and ‘More responsive to the short‐term emergency, changing project or business needs’ were the most significant benefits derived from the use of partnering. More partnering arrangements should be actively introduced into the construction procurement process so that every party can enjoy the full benefits of partnering.
Design and implementation of efficient resampling filters using polyphase recursive all-pass filters

Computationally efficient resampling filters are formed from sets of recursive all-pass subfilters operating in a polyphase structure. These subfilters, exhibiting unity magnitude response, have phase shifts which add constructively in the passband(s) and destructively in the stopband(s). The computational burden for these filters is one-fifth to one-tenth that of conventional resampling filters. The primary advantage of these structures is the relatively low workload per output point. A secondary advantage is the low sensitivity to finite arithmetic and the lack of bit growth in internal states. Disadvantages include the nonuniform phase response of the filter, as well as the newness of the idea and the difficulty in determining coefficients for the filter. <<ETX>>
Thermoelastic Damping in Clamped-Clamped Annular Microplate

In this paper, a linear model of thermoelastic damping in annular microplate is considered for calculating the quality factor of this damping. In this model clamped boundary condition is applied in inner and outer circular edges. In the results, there are critical radius and thickness which are calculated analytically and in these dimensions, the thermoelastic damping becomes maximal. The critical radius and thickness depend on material properties, vibration modes and frequencies, dimensions of microplate.
CLO19-052: Incidence of Ribociclib-Associated Cardiac Conduction Abnormalities in Patients With Hormone Receptor-Positive HER2-Negative Metastatic Breast Cancer: A Combined Analysis of 3 Phase III Randomized Controlled Trials

Introduction: Ribociclib, a cyclin-dependent kinase 4/6 inhibitor, has improved survival in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER 2)-negative advanced breast cancer. Despite remarkable efficacy, potential cardiac toxicities remain a concern. We undertook a combined analysis of randomized controlled trials (RCT) to estimate the incidence of prolongation of corrected QT interval (QTcF) associated with ribociclib. Methods: We performed systematic search of Embase, MEDLINE, and meeting abstracts till September 30, 2018, to find all phase 3 RCTs comparing ribociclib with other agents or placebo in patients with advanced breast cancer and reporting QTc prolongation as adverse event. Mantel-Haenszel method was used to calculate the pooled risk ratio (RR) and absolute risk difference (RD) with 95% CI. Fixed effects model was applied. Heterogeneity was assessed using I2 statistic. Results: Three phase III studies with 2,062 participants were included. Randomization ratio was 1 to 1 in MONALEESA-2 and 7 studies and 2 to 1 in MONALEESA-3 study. I2 statistic was 0, suggesting homogeneity across studies. Prolongation of QTcF >60 msec from baseline was observed in 72 patients (61 had post-baseline QTcF >480 msec) in ribociclib arm, compared to 7 in control arm. Pooled RR for prolongation of QTcF was 7.956 (95%CI: 3.683–17.187; P<.001) and RD was 0.055 (95%CI: 0.040–0.070; P<.001). The risk of having a post-baseline QTcF >480 msec was significantly higher with ribociclib vs control (pooled RR, 4.002; 95%CI: 2.161–7.412; P<.001; and RD, 0.039; 95%CI: 0.024–0.055; P<.001). A total of 16 (1.38%) patients in the ribociclib arm had dose reduction, interruption, or discontinuation due to QTcF prolongation, as opposed to 3 (0.33%) in control arm. Pooled RR and RD were statistically significant at 4.204 (95%CI: 1.333–3.260; P=.014) and 0.012 (95%CI: 0.004–0.021; P=.006), respectively. Conclusion: Advanced breast cancer patients may have cardiac dysfunction due to prior cardiotoxic chemotherapies. In our meta-analysis, ribociclib was associated with significantly higher risk of QTc prolongation and the resultant dosing inconsistencies and discontinuation. Early detection of this potential adverse event and timely intervention are critical.
Actuator Power Reduction Using L-C Oscillator Circuits

Piezoelectric actuators are widely used in smart structural systems to actively control vibration and noise, and to enhance performance. Because of the highly capacitive nature of these actuators, special power amplifiers, capable of delivering large currents, are required to drive these systems. The large currents result in excessive heat generation, and are a cause of concern in designing rotating actuation systems with sliprings for power transmission. In this paper, a means of reducing the current drawn from the power amplifier is investigated. This is accomplished by incorporating the actuator in a tuned L-C oscillator circuit. Non-ideal circuit performance is addressed, along with theoretical limits to possible power savings and practical difficulties in achieving them. The practical limitation of the size of a physical inductor needed for this purpose is recognized and the use of an active pseudo-inductor is investigated. This pseudo-inductor is connected in parallel with a commercially available power amplifier and reduction in current drawn from the amplifier is demonstrated.

Se depositaron recubrimientos de fosfato tricalcico-β/quitosano sobre sustratos de acero 316L via electrodeposicion, a una temperatura de 60 °C, aplicando una corriente de 260 mA. Con el fin de estudiar el efecto del contenido de quitosano en la velocidad de corrosion y la respuesta tribologica de los aceros recubiertos, se utilizaron seis concentraciones de quitosano en la mezcla acuosa. Los enlaces quimicos presentes en las capas fueron estudiados mediante Espectroscopia de Infrarrojo con Transformada de Fourier (FTIR); la cristalinidad de los depositos fue examinada mediante difraccion de rayos-X (DRX); la resistencia a la corrosion del TCP-β/quitosano depositado sobre los aceros se estudio mediante Espectroscopia de Impedancia Electroquimica (EIS) y curvas anodicas Tafel, encontrandose una disminucion del 54% en la velocidad de corrosion para la relacion 50-50, con respecto a 100% TCP. La respuesta tribologica se analizo mediante pin-on-disc, evidenciando una reduccion del 73% en el coeficiente de friccion con mayor concentracion de quitosano.
Role of serum albumin and body mass index in the outcome of major elective abdominal surgery

Background: The prevalence of protein-energy malnutrition in surgical patients is high, ranging from 10% to 54%. The correct assessment of the nutritional studies of such patients is crucial since malnutrition is a risk factor for morbidity and mortality. There is a substantial evidence to show that patients who have signs of malnutrition have a higher risk of complications and an increased risk of death in comparison with patients who have adequate nutritional reserves.Methods: 150 patients were selected for the study. All the collected data was entered in Microsoft Excel sheet. It was then transferred to SPSS ver. 21 software for statistical analysis. Quantitative data was compared by using student’s t-test and chi-square test, qualitative data compared using frequency, standard deviation and percentage. P<0.05 considered as significant.Results: The mean serum albumin was found to be 3.7 gm%±0.3. There was increase rate of complication and duration of hospital stay in those patients with serum albumin <3.5 gm% and BMI>25 kg/m2 and wound infection was found to be the most common complication among these patients.Conclusions: Majority of patients had serum albumin >3.5 gm/dl and more complications were seen with serum albumin <3.5 gm/dl which was statistically significant (p=0.01). Serum albumin is a good prognostic indicator because of its ability to detect protein energy malnutrition.
Quality and Cost - It's Not Either/Or: Making the Case With Cost of Quality

Abstract : Today's organizations must be committed to the continuous pursuit of quality improvement as a requirement for survival. Traditionally, quality and cost have been perceived as a trade-off decision. For this reason, the main purpose and benefit of measuring quality costs has been to demonstrate that improved quality and lower costs go hand-in-hand. Through collection and analysis of these quality costs, improvement is translated into a language management listens to and responds to: money. This article provides tools and techniques to help infuse cost of quality (COQ) concepts into the project team activities to promote quality improvement throughout the full project life cycle.

Modern Control Design for Flexible Wind Turbines

Control can improve energy capture and reduce dynamic loads in wind turbines. In the 1970s and 1980s, wind turbines used classical control designs to regulate power and speed. The methods used, however, were not always successful. Modern turbines are larger, mounted on taller towers, and more dynamically active than their predecessors. Control systems to regulate turbine power and maintain stable, closed-loop behavior in the presence of turbulent wind inflow will be critical for these designs. This report applies modern state-space control design methods to a two-bladed teetering hub upwind machine at the National Wind Technology Center (NWTC), which is managed by the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) in Golden, Colorado. The design objective is to regulate turbine speed and enhance damping in several low-damped flexible modes of the turbine. Starting with simple control algorithms based on linear models, complexity is added incrementally until the desired performance is firmly established.

Planar inverted‐F antennas on implantable medical devices: Meandered type versus spiral type

Based on a planar inverted‐F antenna (PIFA) configuration, two different shaped (meandered and spiral) antennas are designed using finite‐difference time‐domain (FDTD) simulations and measurement results. The antennas are installed on an implantable medical device in a biological‐tissue simulating model. The impedance‐matching and radiation characteristics of two PIFAs are compared in order to observe which shape is more appropriate for wireless communication links of implantable medical devices. Additionally, the effects of the human skin's thickness on the antennas are studied in order to consider medical devices which are implanted in various subcutaneous tissues. © 2006 Wiley Periodicals, Inc.

Causal network inference from gene transcriptional time-series response to glucocorticoids

Gene regulatory network inference is essential to uncover complex relationships among gene pathways and inform downstream experiments, ultimately paving the way for regulatory network re-engineering. Network inference from transcriptional time series data requires accurate, interpretable, and efficient determination of causal relationships among thousands of genes. Here, we develop Bootstrap Elastic net regression from Time Series (BETS), a statistical framework based on Granger causality for the recovery of a directed gene network from transcriptional time series data. BETS uses elastic net regression and stability selection from bootstrapped samples to infer causal relationships among genes. BETS is highly parallelized, enabling efficient analysis of large transcriptional data sets. We show competitive accuracy on a community benchmark, the DREAM4 100-gene network inference challenge, where BETS is one of the fastest among methods of similar performance but additionally infers whether the causal effects are activating or inhibitory. We apply BETS to transcriptional time series data of 2, 768 differentially-expressed genes from A549 cells exposed to glucocorticoids over a period of 12 hours. We identify a network of 2, 768 genes and 31, 945 directed edges (FDR ≤ 0.2). We validate inferred causal network edges using two external data sources: overexpression experiments on the same glucocorticoid system, and genetic variants associated with inferred edges in primary lung tissue in the Genotype-Tissue Expression (GTEx) v6 project. BETS is freely available as an open source software package at https://github.com/lujonathanh/BETS.
Role of CHA2DS2-VASc-HS Score as Predictor for Failed Reperfusion After Fibrinolytic in St-Elevation Myocardial Infarction

Background: Recent studies showed that CHA2DS2-VASc-HS score can effectively predict longterm outcome, hospitalization and severity in CAD. However,the role of this score in predicting failed reperfusion after fibrinolytic in STEMI patients has not been studied extensively. The main objective of this study was to determine whether CHA2DS2VASc-HS score can predict failed reperfusion after fibrinolytic in STEMI patients. Methods: A total of 62 patients with STEMI who undergo fibrinolytic at Haji Adam Malik Hospital since October 2017 until November 2018 were recruited in this cross sectional study. We also performed complete blood count and chest x-ray. CHA2DS2-VASc-HS score was counted before the fibrinolytic started. After the fibrinolytic was done, we assessed the succesfullness with the decrease of chest pain, resolution of ST segments > 50% and aritmia reperfusion criterias. Results: The cut-off value of CHA2DS2-VASc-HS score was 4 (AUC 0.928, 95% CI 0.8610.995, p<0.05). The CHA2DS2-VASc-HS score ≥ 4 group had higher incidence of failed reperfusion. CHA2DS2-VASc-HS score ≥ 4 is considered to predict the incidence of failed reperfusion with a sensitivity of 91.7%, a specificity of 69.2%, NPV of 85.7% and PPV of 80.4%. Multivariate analysis also showed that CHA2DS2-VASc-HS score ≥ 4 was an independent factor that could predict the occurrence of failed reperfusion (OR 23.769, p<0.001). Conclusion: CHA2DS2-VASc-HS score is a simple, very useful and easy-to remember bedside score and an inexpensive indicator which can be used as a prognostic marker for failed reperfusion after fibrinolytic in STEMI. Keyword : CHA2DS2-VASc-HS, fibrinolytic, STEMI.
Promoting Cycling for Transport: Research Needs and Challenges

Abstract Cycling as a mode of transportation has many advantages for both cyclists and society: it is a low-cost, low-polluting, health-improving way to travel. In light of these benefits, a growing number of cities throughout the world are implementing policies to promote cycling, though they continue to struggle to identify the most effective ways to spend their limited resources. In response, transport researchers are also increasingly focusing their efforts on cycling, addressing a broader range of questions than in the past, including: how much cycling is there? What strategies will increase cycling? What are the benefits of increased cycling? This paper reviews the challenges that researchers face in providing answers to these questions by highlighting limitations of the existing research, identifying remaining research needs, and discussing methodological considerations for addressing those needs. Investments in cycling research can pay off by providing a basis for identifying the most effective strategies for increasing cycling and providing more accurate estimates of the benefits that would accrue.

Field tests on telecommunication systems: an evaluation of the radiated emissions by near field probe

There is much literature on the emissions due to apertures while the real situation of a not perfect contact has not received the deserved attention. The typical situation is a long narrow slot closed with fingers or gaskets. This situation was investigated, by using an experimental technique based on the measurements of the magnetic field over the aperture, on two large telecommunication systems. Knowing the magnetic field, under several hypotheses, it is possible to determine the tangential electric field on the aperture and then the electromagnetic field at a desired distance. The calculations and the experimental results were compared.
