Robust PID design based on QFT and convex-concave optimization

This paper presents an automatic loop-shaping method for designing proportional integral derivative controllers. Criteria for load disturbance attenuation, measurement noise injection, set-point response and robustness to plant uncertainty are given. One criterion is chosen to be optimized with the remaining ones as constraints. Two cases are considered: M-constrained integral gain optimization an

Respiratory symptoms are poor predictors of concomitant chronic obstructive pulmonary disease in patients with primary Sjögren’s syndrome

Involvement of the respiratory system, in particular dry airways and chronic obstructive pulmonary disease (COPD), is common in patients with primary Sjögren’s syndrome (pSS). As respiratory symptoms are also common in pSS patients and may have different etiologies, we wanted to evaluate the amount and impact of respiratory symptoms in out-patients with pSS and to assess if such symptoms are relat

Comparable effects of breakfast meals varying in protein source on appetite and subsequent energy intake in healthy males

Purpose: The satiating effect of animal vs plant proteins remains unknown. The present study examined the effects of breakfasts containing animal proteins [milk (AP)], a blend of plant proteins [oat, pea and potato (VP)] or 50:50 mixture of the two (MP) compared with a carbohydrate-rich meal (CHO) on appetite, energy intake (EI) and metabolic measures. Methods: A total of 28 males [mean age 27.4 (

Do we need to evaluate diastolic blood pressure in patients with suspected orthostatic hypotension?

Purpose: The contribution of diastolic blood pressure measurement to the diagnosis of classical orthostatic hypotension is not known. We aimed to explore the prevalence of isolated systolic and diastolic orthostatic hypotension components in patients with syncope and orthostatic intolerance. Methods: A total of 1520 patients aged >15 years with suspected syncope and/or symptoms of orthostatic into

Exploring dimensions of change : the case of MOOC conceptions

This paper addresses a relatively new phenomenon in higher education, Massive Open Online Courses (MOOCs), and explores conceptions around this new and emerging development from the perspective of a number of stakeholders in the university. A phenomenographic approach is adopted. The study explores how different stakeholders at a university perceive the MOOC phenomenon, and reflects on how the man

Mortality benefits from US population-wide reduction in sodium consumption : Projections from 3 modeling approaches

Computer simulations have been used to estimate the mortality benefits from population-wide reductions in dietary sodium, although comparisons of these estimates have not been rigorously evaluated. We used 3 different approaches to model the effect of sodium reduction in the US population over the next 10 years, incorporating evidence for direct effects on cardiovascular disease mortality (method

Clinical preventive services for patients at risk for cardiovascular disease, National Ambulatory Medical Care Survey, 2005-2006

INTRODUCTION: Clinical preventive services can detect diseases early, when they are most treatable, but these services may not be provided as recommended. Assessing the provision of services to patients at risk for cardiovascular disease (CVD) could help identify disparities and areas for improvement.METHODS: We used data on patient visits (n = 21,261) from the National Ambulatory Medical Care Sur

Training mental health professionals to assess and manage suicidal behavior : can provider confidence and practice behaviors be altered?

Remarkably little systematic research has studied the effects of clinical suicidology training on changing practitioner attitudes and behaviors. In the current study we investigated whether training in an empirically-based assessment and treatment approach to suicidal patients administered through a continuing education workshop could meaningfully impact professional practices, clinic policy, clin

Proceedings from the workshop on estimating the contributions of sodium reduction to preventable death

The primary goal of this workshop was to identify the most appropriate method to estimate the potential effect of reduction in sodium consumption on mortality. Difficulty controlling hypertension at the individual level has motivated international, federal, state, and local efforts to identify and implement population-wide strategies to better control this problem; reduction of sodium intake is on

Patients experiences of negative pressure wound therapy at home for the treatment of deep perivascular groin infection after vascular surgery

Aims and objectives: To explore experiences of negative pressure wound therapy at home, in patients with deep perivascular groin infection after vascular surgery and management in daily life. Background: Deep surgical site infection after vascular surgery with exposed vessels often requires long-term treatment with negative pressure wound therapy, and continued therapy at home has become routine.

Hydrologic response of climate change in the source region of the Yangtze River, based on water balance analysis

Due to the large amount of water resources stored in glaciers, permafrost, and lakes, the source region of the Yangtze River (SRYR) is of great importance for the overall basin water flow. For this purpose, a state of art review and calculations were made for the period 1957-2013 using observed hydrological and meteorological data with a water balance approach. Actual evapotranspiration was calcul
