Ranking of sensitive positions based on statistical parameters and cross correlation analysis

Condition Based Monitoring of a machine refers to analysis of the health status of the machine and its components. For this purpose, acoustic data is acquired from various positions on the machine. Acquiring data from large number of sensor positions is not economically viable. It is preferable to have an effective monitoring system that is faster in data acquisition without compromising on the robustness of the system. In fact taking data from too many positions would directly affect its reliability due to various kinds of noises. Therefore there is a need to locate sensitive positions on a machine. These sensitive positions are expected to exhibit appropriate fault characteristics in a much better way as compared to other sensor positions. This paper presents a novel method for ranking sensitive positions based on statistical parameters. While selecting the required number of sensitive positions, cross-correlation among the positions is taken into consideration to avoid redundancy. Furthermore, a standalone application for implementing the same has been developed on Android platform. The scheme and application can be used for many other applications as well, where data is acquired from multiple sensors.
Performance Analysis of a Wing With Multiple Winglets

This effort examined the potential of multi-winglets for the reduction of induced drag without increasing the span of aircraft wings. Wind tunnel models were constructed using a NACA 0012 airfoil section for the untwisted, rectangular wing and flat plates for the winglets. Testing of the configurations occurred over a range of Reynolds numbers from 161,000 to 300,000. Wind tunnel balances provided lift and drag measurements, and laser flow visualization obtained wingtip vortex information. The Cobalt60 unstructured solver generated flow simulations of the experimental configuration via solution of the Euler equations of motion. The results show that certain multi-winglet configurations reduced the wing induced drag and improved L/D by 15-30% compared with the baseline 0012 wing. A substantial increase in lift curve slope occurs with dihedral spread of winglets set at zero incidence relative to the wing. Dihedral spread also distributes the tip vortex. These observations supplement previous results on drag reduction due to lift reorientation with twisted winglets set at negative incidence.
Robust Meter Placement for State Estimation in Active Distribution Systems

The active nature of next generation distribution systems requires a highly accurate real-time monitoring for state estimation and situational awareness. This paper considers the problem of robust placement of a limited number of voltage magnitude meters and phasor measurement units for state estimation in an active distribution system comprising topological reconfigurations. The trace of the inverse of the Fisher information matrix is chosen as criterion for the estimation accuracy. For meter placement in a single configuration distribution system, the greedy approach provides a near-optimal solution as well as a theoretical approximation guarantee. However, for meter placement in an active distribution system, a robust approach is required to optimize the worst case estimation accuracy among all possible configurations of the system. In this paper, a simple robust algorithm, called submodular saturation algorithm, for meter placement in active distribution systems is proposed. Numerical results on three different active distribution systems show that the submodular saturation algorithm outperforms the greedy algorithm and the genetic algorithm in most cases, and provides competitive results in other cases.
Energy Efficiency of a Laminar Jet Methane Flame in a Co-annular Jet of Oxygen-Enriched Air

Improving the energy efficiency is a very important concern as the cost of energy is continuously increasing. Oxygen enriched air is useful in energy saving technologies in combustion. Compared to traditional air/fuel combustion, in which nitrogen, used as the inert gas, siphons away a part of the energy to form flue gas, the oxygen enriched combustion involves higher thermal efficiency, lower loss of heat energy through the flue gas, hence higher available heat [1]. Moreover, it contributes to increase the CO2 in the flue gas, allowing an easier separation for capture process. Diffusion flames are largely used in industry due to the safety link to the separate injection of fuel and air. However, they generally present unsteady behaviour. As shown in a previous paper [2], in the configuration of a coaxial burner, a flame initially lifted off the burner by a co-jet of an air, is gradually dropped down until reattachment when oxygen is incrementally added to air. The stabilization effect of oxygen addition on the flame behaviour is noticeable even at low air enrichment (<25%). The flame adiabatic temperature is strongly increased as oxygen is added: from 2200K for a methane/air flame to 3100K for a methane/oxygen flame. Here, we propose to characterize the flame behaviour through the measurement of the heat transmitted to a heat exchanger as a function of injection velocities and oxygen enrichment.

Detection Performance of Signals in Dependent Noise From a Gaussian Mixture Uncertainty Class.

Abstract : Detection performance in terms of probabilities of detection and false alarm (PD and PF) is derived for a desired signal embedded in dependent (correlated) multivariate noise from a Gaussian mixture uncertainty class. This uncertainty class is defined using upper and lower bounding functions on the univariate Gaussian mixing distribution function. For a given detector operating point, expressions for PD and PF are derived. In addition, nontrivial lower and upper bounds of performance are derived which are functions of the bounding functions of the uncertainty class, the detection threshold, and the desired signal strength (only for PD).
Effects of live weight and energy intake on nitrogen balance and total N requirement of lambs

I. Results of 298 nitrogen balance studies from experiments with male cross-bred lambs, ranging in weight from 3 to 38 kg, which had been either fasted, or fed entirely on liquid diets of varying protein content at various energy intakes up to ad lib. intake, were used to quantitatively describe the effects of the amount and quality of absorbed protein, energy intake and live weight on N balance and total N requirement of lambs. 2. When N intake was less than the amount required, N balance was independent of energy intake, but linearly related to absorbed N and metabolic body-weight (live eight""^). In the fitted relationship, the coefficient of absorbed N was shown to be an estimate of the biological value of absorbed protein and the coefficient of metabolic body-weight was an estimate of the loss of endogenous N in both urine and faeces. For the milk-based diets used in the experiment biological value was 0'72 and the total endogenous N loss in urine and faeces was 148 mg N/kg075 per d. 3. When N intake was in excess of the amount required, N balance in lambs of a constant live weight increased linearly with metabolizable energy (ME) intake, at a rate that decreased with increasing live weight. Similarly at constant ME intake, N balance was a curvilinear decreasing function of metabolic body-weight. When N balance was expressed per unit metabolic body-weight, it was constant for lambs of all weights when ME intake was about 0.23 M J/kg0'76 per d, but it decreased linearly with increasing metabolic body-weight for ME intakes above this level. 4. N balance of fasted lambs was several times less than predicted by either of the relationships established for fed animals, and was found to be linearly related to metabolic bodyweight. G . The effects of enerm intake and live weight on the total N requirement of lambs were -_ determined. When total N requirement was expressed per unit of energy intake, it was found to be constant at 0-9 g N/MJ ME for all lambs irrespective of live weight when ME intake was 0.23 MJ/kg@75 per d. However, as ME intake/unit metabolic body-weight was raised above this level, N requirement/unit ME intake increased for lambs weighing less than c. 23 kg, but decreased for heavier animals.
Couponing Strategies in Competition between a National Brand and a Private Label Product

This paper explores the couponing strategies when a national brand competes with a store brand by discussing three different kinds of coupons: manufacturers’ coupons, retailers’ national brand coupons, and retailers’ private label coupons. We show that the positioning of the private label product in terms of quality and feature differentiation from the national brand play an important role in determining the face value of the manufacturer's coupon and retailer's national brand coupon. In particular, a larger degree of feature differentiation drives the manufacturer to increase its coupon value, and the retailer responds by decreasing the value of its own coupon for the brand name product. In contrast, with an increase in private label quality, the couponing strategies taken by the manufacturer and the retailer depend on which segment of consumers is in the market for the private label product. Additionally, the retailer's private label coupon value is only impacted by the difference in consumers’ willingness to pay but not by private label positioning. Empirical results on the effect of feature differentiation on national brand and private label coupon values are consistent with our theoretical predictions.
Strength training and older women: a cross-sectional study examining factors related to exercise adherence.

BACKGROUND Despite the recognized health benefits, few older women participate in strength-training exercises. METHODS The purpose of this study was to examine factors related to older women's adherence to strength training after participation in the StrongWomen Program, a nationally disseminated community program. Adherence was defined as > or =4 months of twice-weekly strength training. Surveys were sent to 970 program participants from 23 states and to participants' corresponding program leaders. Five-hundred fifty-seven participants responded (57%). RESULTS Of respondents who completed surveys (527), 79% (415) adhered to strength training; adherers reported a mean of 14.1 +/- 9.1 months of strength training. Logistic-regression analysis revealed that exercise adherence was positively associated with age (p = .001), higher lifetime physical activity levels (p = .045), better perceived health (p = .003), leader's sports participation (p = .028), and leader's prior experience leading programs (p = .006). CONCLUSION These data lend insight to factors that may be related to exercise adherence among midlife and older women.
THE PECOS COUNTY , TEXAS HAIL STORMS OF 10 MAY 2002 : A NULL TORNADO EVENT FROM A WARNING DECISION PERSPECTIVE

Recent training provided to forecasters in the National Weather Service emphasizes the importance of maintaining high levels of situational awareness and the resulting benefits to the warning decision making process. With the aid of radar animations and corresponding video clips captured by storm spotters, this paper will examine how several scientific and human factors combined to increase situational awareness, and allowed forecasters to make critical warning decisions regarding severe weather threats during a significant hail event in West Texas.

Dynamic voltage regulation using SVCs

Voltage stability is a major concern when planning and operating electrical power systems. As demand for electric power increases, power systems are stressed more and more. The FACTS family of components were introduced to utilize the existing grid to a higher degree, while still maintaining system stability. This thesis investigates if the addition of another SVC to the Swedish national grid could increase the power transfer from north to south. Placement of the SVC was based on two different indices used to indicate weak areas of the grid; the Q-V sensitivity index and the V CPI index. Simulations were performed with both the added SVC and regular switched shunt compensation and the results were compared against each other. Studies were also performed to investigate the effect of an SVC installed at the grid connection of a large (1000 MW) wind farm. Simulations were performed where the wind farm was modeled by either doubly fed induction generators (DFIG) or single cage induction generators. This simulation study was performed using PSS TM E, based on a detailed model of the Nordic power system as it existed in 2007. The studies showed that adding a ±200 MVAr SVC to the Swedish national grid could increase the power transfer by 150 MW, where an equally rated switched shunt capacitor/reactor would result in a 100 MW increase. In these studies, the transfer capacity was limited by voltage collapse situations. However, installing the same ±200 MVAr SVC at the connection of a large wind farm showed an increase in power transfer by 1000 MW, while the switched shunt compensation only resulted in a 500 MW increase. In the simulations that showed the greatest increase in transfer capacity, the added wind farm was modeled by single-cage induction generators. In this case the transfer capacity was limited by transient stability problems.
Gemcitabine plus Paclitaxel as First-Line Chemotherapy for Patients with Advanced Breast Cancer

Objectives: To assess the efficacy and tolerability of gemcitabine and paclitaxel as first-line treatment in advanced breast cancer. Methods: Patients with histologically confirmed metastatic or metastatic plus locally advanced breast cancer received gemcitabine 1,200 mg/m2 on days 1 and 8 and paclitaxel 175 mg/m2 on day 1 every 21 days for 8 cycles. Results: From December 1999 to August 2001, 45 patients, with a median age of 53.5 years (range, 22–77), received a total of 260 cycles. All were assessable for response and toxicity. Twenty-seven patients had prior adjuvant therapy. Hormonal receptor status was positive in 31.1% and negative in 40.0% of patients. Main metastatic sites included soft tissue (62.2%) and lung (53.3%). The objective response rate was 66.7%; complete response, 22.2%; partial response, 44.4%; stable disease, 15.6%; progressive disease, 17.8%. Median duration of response was 18 months and median time to tumor progression was 11 months. Grade 3/4 leukopenia, neutropenia, and thrombocytopenia developed in 13.3% of patients, and 15.5% developed grade 3/4 mucositis. No treatment-related deaths occurred. Median overall survival was 19 months. Conclusion: Gemcitabine plus paclitaxel is an active combination with a favorable toxicity profile as first-line treatment for patients with advanced breast cancer.
"?- Variation in Northern Jordanian Arabic: Manifestations of Standard Origin

Abstract The study investigates the phonetic behavior of the glottal stop in different inword – positions (initial, medial, final) and across word-boundary in Northern Jordanian Arabic (NJA), and attempts to examine its convergence to that behavior described for classical Arabic in standard references. The study provides detailed quantitative data about ? variation in NJA, and concludes that NJA is essentially similar to the standard model in demonstrating the sound's different variants, viz., fullyarticulated ? , weak glottal constriction, substitution and deletion under similar phonetic conditioning. The study also finds some slight deviations from the standard possibly attributed to differences in the linguistic practice in both varieties, and reveals some innovations, especially in the substitution process.
Effect of DA-9701 on the Normal Motility and Clonidine-induced Hypomotility of the Gastric Antrum in Rats

Background/Aims DA-9701 is a novel prokinetic agent. In the present study, we investigated the effect of DA-9701 on the motility of the gastric antrum in the normal and clonidine-induced hypomotility in an in vivo animal model. Methods A strain gauge force transducer was sutured on the gastric antrum to measure the contractile activity in rats. A total of 28 rats were subclassified into the 4 groups: (1) the placebo group, (2) the DA-9701 group, (3) the placebo group in the clonidine-pretreated rats, and (4) the DA-9701 group in the clonidine-pretreated rats. After the basal recording, either placebo (3% [w/v] hydroxypropylmethyl cellulose) or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. In the clonidine-pretreated rats, either placebo or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. Results Oral administration of DA-9701 did not significantly alter the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the placebo group. The administration of clonidine decreased the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the administration of placebo. This reduction of the antral motility by the administration of clonidine was not observed in the clonidine-pretreated DA-9701 group. The percentage of the motility index in the postprandial period was significantly greater in the clonidine-pretreated DA-9701 group, compared with the clonidine-pretreated placebo group. Conclusions DA-9701 improves the hypomotility of the gastric antrum induced by clonidine, suggesting its gastroprokinetic effect in the pathologic condition.
Poverty eradication and decreased human papilloma virus related cancer of the penis and vulva in Jamaica

Summary Human papilloma virus causes genital cancers. Decreases in cervical cancer have been reported to be due to comprehensive screening programmes difficult to replicate in poorer countries. HPV cancer may be related to poverty. In Jamaica, we have seen decreases in cancer of the penis and vulva and there has also been a decrease in poverty. The decrease cannot be attributed to screening. We believe elimination of poverty has decreased HPV persistence and decreased cancer rates.
Shotgun proteomic analysis of sarcoplasmic reticulum preparations from rabbit skeletal muscle

To obtain a comprehensive understanding of proteins involved in excitation–contraction coupling, a catalog of proteins from sarcoplasmic reticulum (SR) membrane fractions of New Zealand white rabbit skeletal muscle was analyzed by an optimized shotgun proteomic method. Light and heavy SR membrane fractions were obtained by nonlinear sucrose gradient centrifugation and separated by 1DE followed by a highly reproducible, automated LC‐MS/MS on the hybrid linear ion trap (LTQ) Orbitrap mass spectrometer. By integrating as low as 1% false discovery rate as one of the features for quality control method, 483 proteins were identified from both of the two independent SR preparations. Proteins involved in calcium release unit complex, including ryanodine receptor 1, dihydropyridine receptor, calmodulin, triadin, junctin, and calsequestrin, were all detected, which offered validation for this protein identification method. Rigorous bioinformatics analysis was performed. Protein pI value, molecular weight range, hydrophobicity index, and transmembrane region were calculated using bioinformatics softwares. Eighty‐three proteins were classified as hydrophobic proteins and 175 proteins were recognized as membrane proteins. Based on the proteomic analysis results, we found as the first time that not only transverse tubule but also mitochondrion physically connected to SR. The complete mapping of these proteomes may help in the elucidation of the process of excitation–contraction coupling and excitation–metabolism coupling.
The German Ideology by Karl Marx and

The first premise of all human history is, of course, the existence of living human individuals. Thus the first fact to be established is the physical organisation of these individuals and their consequent relation to the rest of nature. Of course, we cannot here go either into the actual physical nature of man, or into the natural conditions in which man finds himself — geological, hydrographical, climatic and so on. The writing of history must always set out from these natural bases and their modification in the course of history through the action of men.
INDENTATION TESTING PARAMETER IDENTIFICATION USING AN OPTIMIZATION PROCEDURE BASED ON GENETIC ALGORITHMS

Nanoindentation testing can be used as experimental technique for determining the material parameters. This paper presents a sequential optimization method for determining mechanical material parameters from indentation experiments with inhomogeneous stress and strain fields. The purpose of this inverse problem is to determine the elasto-viscoplastic material parameters that lead to the most accurate agreement between experimental data and indentation simulation results. A sequential combination of an optimization method based on evolutionary genetic algorithms, with a more classical gradient-based optimization algorithm, is proposed. The sequential optimization procedure works as follows: the genetic algorithm is generating starting points, and for each starting point the gradient-based nonlinear optimization solver is launched. The identifiability of material parameters and the reliability of the proposed method are proved by the examples tested so far.
