In a watershed, sediment arises due to the erosion and some factors such as pastures destruction,change users, no reasonable cultivation. That causes problems such as sedimentation in reservoirs andreduces their useful volume, reducing water quality in agricultural consumption; reduce the efficiencyof hydraulic structures and some other environmental problems. Changes in sediment load in a rive...

Prediction of highly non-linear behaviour of suspended sediment flow in rivers is of prime importance in environmental studies and watershed management. In this study, the predictive performance of artificial neural network (ANN) integrated with genetic algorithm (GA) was assessed. GA was used to optimize the parameters and architecture of the ANN. Five simulation scenarios (S1–S5) were develop...

BACKGROUND Older people are at increased risk of falls after hospital discharge. This study aimed to describe the circumstances of falls in the six months after hospital discharge and to identify factors associated with the time and location of these falls. METHODS Participants in this randomized controlled study comprised fallers (n = 138) who were part of a prospective observational cohort ...

BACKGROUND Inadequate discharge planning following inpatient stays is a major issue in the provision of a high standard of care for patients who receive psychiatric treatment. Studies have shown that half of patients who had no pre-discharge contact with outpatient services do not keep their first outpatient appointment. Additionally, discharged patients who are not well linked to their outpati...

This study assessed performance on a screening test of competency to consent to treatment, the Hopkins Competency Assessment Test (HCAT), in a population diagnosed with chronic mental illness, and examined the relationship between HCAT performance and functional status at discharge. We hypothesized that patients with chronic mental illness who failed the HCAT would also have problems in perform...

Prediction of highly non linear behavior of suspended sediment flow in rivers has prime importance in the field of water resources engineering. In this study the predictive performance of two Artificial Neural Networks (ANNs) namely, the Radial Basis Function (RBF) Network and the Multi Layer Feed Forward (MLFF) Network have been compared. Time series data of daily suspended sediment discharge ...

This paper presents a method to determine the internal resistance of a bank of deep-cycle lead acid batteries that are part of a stand-alone photo-voltaic system. Both the charge and discharge resistances are calculated as a function of the state-of-charge (SOC) of the battery from daily variations in battery terminal voltage as well as charge and discharge currents. The method is illustrated b...

BACKGROUND Assessment of mobility in geriatric hospital units relies primarily on subjective observation or patient self-reports. We objectively examined the gait speed of hospitalized older patients. METHODS Prospective study of 322 patients 65 years or older admitted from the community to a geriatric hospital unit between March 2008 and October 2009. Associations of gait speed (in meters pe...

OBJECTIVE The purpose of this study was to evaluate the relationship between improvement of health-related quality of life (QOL) and participation in self-care activities and coronary risk factor management at 6 months after discharge for acute myocardial infarction (AMI) patients treated with percutaneous coronary intervention (PCI). METHODS A total of 118 patients were asked to complete the...
