An optimizing model for solving outsourcing supplier selecting problem based on particle swarm algorithm

ABSTRACT The characteristics of decentralization, diversification, and dynamics of outsourcing resources put forward higher requirements for the supplier selection in manufacturing enterprises. For building materials equipment manufacturing enterprises (BMEM), due to the complex product structure, the demand for outsourcing resources is very large. The traditional method is difficult to meet the needs of current outsourcer evaluation and selection. In order to solve the problem, this paper establishes an outsourcing supplier selection model based on the quality, price, delivery time, reliability, and availability of outsourced suppliers. And then, a hybrid supplier selection algorithm based on Analytic Hierarchy Process (AHP) and Particle Swarm Optimization (PSO) is designed in this paper. Finally, the model and algorithm are verified and analyzed in BMEM. The paper also compares the algorithm with genetic algorithm (GA) and ant colony optimization (ACO). The experimental results show that the model can effectively improve the effectiveness and reliability of outsourcing supplier selection.

Robotic Walkers for Children and Youth with Cerebral Palsy: A Review of Past Successes and Ongoing Advancement

Each child with a disability deserves the support required to achieve their maximum physical potential, optimal participation and an active lifestyle throughout their lifespan. In this paper, we aim to highlight past successes, present work and share a vision for future advancements in robotic gait technologies that enable walking in children and youth with severe physical disabilities. We will summarize work which demonstrates how a robotic walker with a lift and body weight support system has shown great promise in mobilization, exercise and participation in youth and young adults with Cerebral Palsy (CP). This study was conducted in 3 phases; 1) a case study, 2) a pilot study evaluating mobility in a clinical setting, and 3) a study focusing on training and participation in a community setting. Secondly, we will describe the planned assessment of the Trexo Plus, a walker and wearable lower extremity robotic device combination, in younger children with significant physical involvement secondary to CP. This device allows precise repetition of normal gait patterns while controlling range of motion at the hip, knee and ankle. Lastly, we will highlight international innovative robotic work which has produced a novel robotic platform with a partial body weight support system (PBWS), active system for adapting hip height and an exoskeleton with joint motion control. A multimodal human-robot interface (MHRI) accompanies the unique walker system which assesses intent to move, posture and balance and gait patterns. This system has the potential to allow therapists to construct and precisely evaluate unique robot facilitated programming. There is a new generation of robotic devices providing the means for individuals with CP to walk independently. With a look to the future, we endeavour to evaluate and facilitate the development of this robotic technology as it is integrated into clinical care, activity enhancement and community participation.
A fast pitch searching algorithm using correlation characteristics in CELP vocoder

The major drawback in the code excited linear prediction (CELP) type vocoders is their large computational requirements. In the present paper a simple method is proposed to reduce the pitch searching time in the pitch filter almost without degradation of quality. Based upon the observational regularity of the correlation function of speech, the searching range can be restricted to the positive side in pitch search. This is done by skipping the negative side with the width which is estimated from the previous positive envelope. In addition to that, the maximum number of available lags can be limited by the threshold, LT, which is set on 58 empirically. So, only the limited numbers of lags are considered in pitch search, which is less than a half of that of the full search method. By using the proposed method in pitch search, its required computations are greatly reduced. Experimental results show 51% time reduction almost without lowering the speech quality in segmental SNR measures. <<ETX>>

The Alteration of Atrial Structure and Electrophysiological Charact eristics in Abdominal Aorta Banded Rats

Objective To investigate the alterations of atrial st ru cture and electrophysiologicalcharacteristics in abdominal banded aorta rats. Methods Male Sprague-Dawley rats were randomly divided in to unoperated group (control group, n=12) and abdominal aorta banded group ( experimental group, n=12) , and were fed for four weeks. Rats were anesthet ized after four weeks, I lead body surface ECG was recorded, a catheter was plac ed in left common carotid artery for measuring systolic and diastolic blood pres sure. Interatrial conduction time (IACT) and atrial response to burst atrial pa cing were evaluated in Langendorff-perfused setting. Tissue of atrium was stai ned with Masson trichrome; the ratio of the interstitial fibriosis area to the t otal area in atrial myocardium was measured. Results Contrast to control group, plasma angiotensin Ⅱ(Ang Ⅱ) level was increased significant ly in experimental group [(1.76±0.5 vs 0.97±0.4)ng/mL, P0.01]. R ats in experimental group had longer P wave duration and IACT than in control g roup [(27.8±5.1 vs 23±4.5)ms, P0.05 and (37.3±5 vs 23.1±3.3)ms ,P0.01 respectively]. AF were induced in 4/12 rats in experimental g roup, while 0/12 in control group. A significant increases in interstitial atri al fibrosis was present in experimental group compared with control group (P 0.01). The extent of atrial fibrosis was related to inducible AF ( OR=5.75,P0.01). Conclusion The extent of atrial fibro sis was increased in abdominal aorta banded rats. Although longer P wave duratio n and IACT are present, there is no change in atrial effective refractory perio d. Increased atrial fibrosis may be attributed to inducible AF. =
Access Process of Data-Flow in Cross-Domain Usage Control Model Based on XACML

With the rapid development of information technology, more and more requesters need accessing the services in different access domains, which make the access process in cross-domain become more difficultly. The traditional access control models couldn’t solve the access process for their design limitations and diversity access policies. Usage control model (UCON) was proposed to strengthen the expression of access control model, but UCON is only a conceptual model. How to use the UCON in access process It is worthwhile to further study. Extensible access control markup language (XACML) is an open standard XML-based language, which can be used to describe the security policy. In order to solve the access process in different access domains, based on XACML, access process of data-flow in cross-domain usage control model is proposed in the paper. Access process of data-flow cross different domains in XACML is introduced to solve the cross-domain problem. Finally, a small example is given to verify the effectiveness of access process.

Randomized phase II trial of uracil/tegafur and cisplatin versus pemetrexed and cisplatin with concurrent thoracic radiotherapy for locally advanced unresectable stage III non-squamous non-small cell lung cancer: NJLCG1001

Background The optimal regimen for concurrent chemoradiotherapy (CCRT) of locally advanced non-squamous non-small cell lung cancer (NSCLC) was not definitive. We conducted randomized phase II study, NJLCG0601, and chemoradiotherapy with uracil/tegafur (UFT) and cisplatin achieved promising efficacy without severe toxicities. Here, we evaluated between this regimen and pemetrexed plus cisplatin in chemoradiotherapy for stage III non-squamous NSCLC. Methods Patients with inoperable stage III non-squamous NSCLC were randomly assigned in a 1:1 ratio to UFT 400 mg/m2 on days 1–14 and 29–42, and cisplatin 80 mg/m2 on days 8 and 36 (UP), or cisplatin 75 mg/m2 and pemetrexed 500 mg/m2 on days 1, 22, and 43 (PP). Involved-field radiotherapy (IFRT) underwent from day 1 to a total dose of 66 Gy in 33 fractions. Consolidation chemotherapy after CCRT was prohibited for this study. The primary endpoint was defined as 2-year overall survival (OS). This trial was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN000003948). Results From November 2010 to June 2017, 86 patients were entered from 11 institutions. Median follow-up was 54 months. Of the 85 eligible patients, the 2-year OS rate was 78.6% (95% CI, 62.8–88.3%) in UP and 85.5% (95% CI, 70.5–93.2%) in PP. Median PFS and OS was 12.3 and 64.2 months in UP, 26.2 months and not reached in PP, respectively. Grade 3/4 febrile neutropenia was more frequent in the UP group (14.0% vs. 2.0%). Conclusions Both UP and PP with IFRT achieved the expected 2-year OS. PP engendered more favorable OS and PFS compared to UP in terms.
Spectral Quality of Light Can Affect Energy Consumption and Energy-use Efficiency of Electrical Lighting in Indoor Lettuce Farming

High energy-use cost for electric lighting is one of the major issues challenging sustainability of the indoor lettuce-farming industry. Thus, maximizing electrical energy-use efficiency (EUE, g·KWh−1), defined as the ratio of dry matter production (g) to electrical energy consumption (EEC, KWh−1), is crucial during indoor production. Light-emitting diodes (LEDs) are energy efficient and highly suitable for indoor farms. Research on optimal spectral quality of LEDs for lettuce growth is extensive; however, there is limited research examining LED spectral quality effects on EEC and EUE. Photon efficiency, defined as the ratio of light output to electrical energy input (PE, µmol·J−1), generally is used for selection of LED fixtures. Because PE does not account for differences in emitted light spectrum, it is not clear whether light-fixture selection based on PE can maximize EUE in lettuce production. This study comprised two experiments. In Expt. 1, we used four “phosphor-converted” commercial LEDs with different light intensities and spectra to model the effect of light spectral quality on lettuce shoot dry weight (SDW), EEC, and EUE. We also evaluated relations between EUE vs. PE and EUE vs. PER (PE based on red light) for indoor lettuce production. Results indicated that light spectral quality affected SDW, EEC, and EUE in lettuce production. Fitted models indicated that EEC increased linearly with increasing percentage of red-light output and was unaffected by other spectral colors or ratios. However, EUE increased in a curvilinear fashion with an increasing ratio of red to blue (R:B) light and reached a maximum at a ratio of 4.47. Similar to EUE, SDW also responded in a curvilinear fashion to R:B. Results also indicated that EUE correlated poorly with PE but linearly to PER. In Expt. 2, we grew three lettuce varieties under two commercial LED fixtures. They had similar levels of PE but different percentages of red, R:B, and PER values. Regardless of the variety, fixtures with greater percentages of red, R:B, and PER significantly increased EUE. We conclude that red-light quality is an important determinant of EUE and growers should select fixtures based on R:B and high PER in indoor lettuce farming.
Diet in Pregnancy: A Randomized Controlled Trial of Nutritional Supplements

This is a detailed description of the methodology and collection of data, as well as an elaboration of the conclusions, performed by the authors in their controversial article "A Randomized Controlled Trial of Prenatal Nutritional Supplementation in New York City" ( Pediatrics 1980;65:683-697). Starting with approximately 800 mothers who were expected to have been deprived of protein, the authors gave to one third a protein supplement, to one third a balanced protein-calorie supplement, and to one third routine clinical care. After recruitment of the study groups, it was found that the nutritional deficiency most likely to be present was one of calories rather than protein. The high-protein supplement seemed to have an adverse effect on the outcome of some pregnancies, despite increased maternal weight gain. Some psychological effects at 1 year of age may have been produced by the high-protein supplement during pregnancy. This study is bound to be quoted frequently
The use of biologics for autoimmune rheumatic diseases in fertility and pregnancy

In an age where autoimmune rheumatic diseases are successfully managed with biologics, their discontinuation in pregnancy is inadvisable without careful forethought; maternal disease activity is associated with adverse pregnancy outcomes, which has long-term implications for both mother and offspring. We aim to provide clinicians with the necessary tools to facilitate decision-making – when a biologic should be used, when it can be discontinued in pregnancy if appropriate. The pathophysiology of these biologic molecules and their effect on fertility, pregnancy and parturition are discussed. A summary of the 2016 international guidelines (European League Against Rheumatism and British Society in Rheumatology) on biologics in pregnancy has been tabulated; more recent publications are discussed in depth. Data on transplacental-transfer ratios and breastmilk excretion rates are also included. Biologic effects on organogenesis, their implications for the exposed infant in terms of infection risks and vaccination requirements are included, and future directions for research proposed.
Analyzing voice using Wavelet-Hilbert transform

Time-frequency and time-scale transforms are one of the powerful mathematical methods for feature extraction of non-stationary signals such as voice. Modified Fourier-based transforms and Wavelet transforms are well-known among them. Voice can be analyzed by these influential methods but normally with some serious limitations and inadequacies. This paper proposes a new approach based on Wavelet-Hilbert Transform (WHT), for the analysis of voice signals. The mathematical model of a WHT is described. The obtained results by the proposed method show some advantages over the Fourier based algorithms.

Decoding stillbirths using the Relevant Condition at Death classification: Study from the developing world

Objective: To determine the stillbirth rate in 2017 at Christian Medical College, a tertiary care perinatal center in South India, and to identify causes for the various stillbirths that occurred using the Relevant Condition at Death (ReCoDe) classification. Material and Methods: Medical records of the women with stillbirths between January 1st, to December 31st, 2017, were retrieved and analyzed using the SPSS software (IBM, version 23). The study was approved by the institutional review board (minute no: 11273, retro dated: 28/3/2018). Results: Of the total 14696 deliveries between January 1st, 2017, to December 31st, 2017, there were 247 stillbirths, a rate of 16.8 per 1000 births. Maternal factors: 156 (64.2%) women were booked and the rest were un-booked. Hypertensive disorders of pregnancy were detected in 27.5% (n=67). A greater number of un-booked women had gestational hypertension as compared with booked women (41% vs 24%, p=0.005). Fetal characteristics: still births secondary to lethal congenital anomalies were seen in 18.2% (n=45). Lethal congenital anomalies were diagnosed 10 times more in the booked patients than un-booked ones (24.7% vs 2.3%, p=0.001). Obstetric factors: one or two previous miscarriages were seen in 29.5% cases. Seventeen women (6.9%) had a prior stillbirth. ReCoDe Classification: we were able to successfully classify 84.2% of the stillbirths, leaving 15.78% unclassified. Fetal growth restriction secondary to uteroplacental insufficiency was found in 25.9% cases. Of the placental causes, abruption accounted for 10.9% of cases. Medical co-morbidities were seen in 46.5% pregnancies. Conclusion: The ReCoDe method of classifying stillbirths is useful in the developing world. It helped to elucidate the cause for stillbirths in 84.2% of cases. The majority of cases in our set were due to fetal growth restriction, hypertensive disorders of pregnancy, and uteroplacental insufficiency. Stillbirths can be prevented by a comprehensive antenatal care system, early recognition, and close monitoring of high-risk pregnancies.
