Abstract Maintenance is an important aspect in the lifecycle of communication network devices. Prevalent problems in the maintenance of communication networks include inconvenient data carrying and sub-optimal scheduling of work orders, which significantly restrict the efficiency of maintenance work. Moreover, most maintenance systems are still based on cloud architectures that slow down data transfer. With a focus on the completion time, quality, and load balancing of maintenance work, we propose in this paper a learning-based virus evolutionary genetic algorithm with multiple quality-of-service (QoS) constraints to implement intelligent scheduling in an edge network. The algorithm maintains the More >

Abstract Background: Adults with congenital heart disease (ACHD) have traditionally been viewed as an underinsured population. Whether this is true in the Affordable Care Act era is unknown. We determined insurance patterns in ACHD patients compared to the non-ACHD cardiology population in a contemporary cohort.
Methods: All cardiology outpatient visits between July 2016 and February 2017 to a large referral center in the United States were reviewed. The primary payer was categorized as health maintenance organization (HMO), preferred provider organization (PPO), Medicare, Medicaid, self-pay, or other. Diagnosis and lesion severity of ACHD were extracted from ICD-10 diagnostic codes… More >

Abstract TThe goals of this study were (1) to determinate the cultural practice of Solidago chilensis native Asteraceae from Argentina which have to be used in low maintenance gardening and (2) to describe germination and seedlings of S. chilensis and its morphology type. Germination assay treatments (3 repetitions/50 fruits/year) were intact non-scarified and scarified fruits (achenies), collected in La Mesada, La Calera, Dpto. Colón (Córdoba, Argentina) between 2011-2014. Statistical tests were performed. 50 rhizome cuttings, obtained from mother plants selected in the field, were cultivated in same conditions of the field-substrate with or without rooting solution, and they More >

Abstract This paper presents a simple graphic method for detecting and classifying faults in point mechanisms based on the study of some statistical parameters of the force and current signals of the point machine. Principal Components Analysis (PCA) employed in order to reduce the number of these parameters. PCA is utilised in this paper for modifying the parameter dataset, and reducing the coordinate system by linear transformation. It is then possible to plot the new coordinate system in 2 or 3 dimensions, where the faults can be detected and identified. In this work most of the More >

Abstract A methodology to maintain the configuration of inflated membrane structures using shape memory alloy (SMA) film actuator is numerically investigated. The two- dimensional incremental formulation of the SMA constitutive model is developed. New parameters related to the thermodynamic energy equation are introduced to describe more general behaviors of the SMA film. With numerical algorithm of wrinkling and SMAs, the interactions between the inflated membrane structure and the SMA film are investigated by using a finite element program. The effectiveness of SMA film to control the configuration of an inflated membrane structure is examined. To demonstrate More >

Abstract Objectives: The study evaluates the effect of chronic usage, beyond the recommended maintenance schedule, on the efficacy of electromagnetic lithotripter. To our knowledge, there is no publication investigating the effect of chronic usage on the electromagnetic lithotripter, despite the maintenance schedule established by the manufacturers. Our goal is to verify if the acoustic parameters of the shock wave changed with usage, and if this change could be associated with change in clinical efficacy.
Methods: This study lasted 18 months. Every 6 months the lithotripter's efficacy was evaluated in two ways: objectively and clinically. Objective efficacy was… More >

Abstract This paper presents an overview of the achievements of a research and development project sponsored by the European Commission in the general area of Key Actions and New Perspectives in Aeronautics. The project was coordinated by Alenia and involved partners from major European Aircraft and Helicopter manufactures as well as research institutions and universities. The project was in support of EU policies on energy and environment, in addition to those on transport, economic and social cohesion, industry and, of course, research and technology.
The overall objective of Advanced Design concepts and Maintenance by Integrated risk Evaluation… More >

Abstract Objective: To assess success rates in ability to penetrate (Sexual Encounter Profile question 2 [SEP2]) and maintain erections to completion of intercourse (SEP3) from time of dosing to start of sexual activity in a retrospective analysis of two pivotal trials.
Methods: In two randomized, double-blind studies, men with ED for >6 months received vardenafil 5 mg, 10 mg, or 20 mg or placebo for 12-26 weeks. Patients were instructed to start sexual activity 1 hour after dosing. In this retrospective pooled analysis, patient diary questions through week 12 were analyzed, providing attempt data was recorded 0-12 hours… More >
