“…Recent interventional studies indicate that home based rehabilitation can be effective in home-dwelling elderly persons with functional impairments [ 23 ], but such measures seemed to be under-utilized in the districts we studied. Promising results also exist from interventions aimed at improved cooperation between hospitals and primary health care [ 10 ] and in identifying patients at particular risk of hospital readmittance [ 14 ]. In our opinion, a reasonable next step for model development studies should be to redirect the content of the routine health services provided at home more towards tailored observations of disease status, functional status, and drug effects in combination with rehabilitation, and with the health service input being flexible and open for day-to-day individualization as deemed appropriate by the health personnel themselves.…”

“…Several patients used opioid analgesics, anxiolytics or hypnotic drugs posing a high risk of delirium, falls and gastrointestinal problems. It is likely that if the nurses to a larger degree were given the time, competence and opportunity to monitor important health indicators and coordinate medical follow-up when necessary, health and function of this frail patient group might be better maintained and hospitalisations avoided [ 14 , 30 ]. This would, however, require an organisational model in which the nurses were authorized to adapt the services to the patients’ varying health needs from day to day, and were not bound to follow detailed service descriptions and schedules.…”

“…This is a large patient group with extensive need of healthcare ([ 13 ], p. 51). Internationally, frequent readmissions are common in frail, home-dwelling elderly, and may also represent a burden and a risk factor for further functional decline [ 14 ]. In order to tailor the community care services to the needs of frail patients, precise knowledge about their health and functional status is needed.…”

Background: In Norway, as in many Western countries, a shift from institutional care to home care is taking place. Our knowledge is limited regarding which needs for nursing interventions patients being cared for in their home have, and how they are met. We aimed at assessing aspects of health and function in a representative sample of the most vulnerable home-dwelling elderly, to identify their needs for nursing interventions and how these needs were met. Methods: In this observational study we included patients aged 75+ living in their own homes in Oslo, who received daily home care, had three or more chronic diagnoses, received daily medication, and had been hospitalized during the last year. Focused attention and cognitive processing speed were assessed with the Trail Making Test A (TMT-A), handgrip strength was used as a measure of sarcopenia, mobility was assessed with the "Timed Up-and-Go" test, and independence in primary activities of daily living by the Barthel Index. Diagnoses and medication were collected from electronic medical records. For each diagnosis, medication and functional impairment, a consensus group defined which nursing service that the particular condition necessitated. We then assessed whether these needs were fulfilled for each participant. Results: Of 150 eligible patients, 83 were included (mean age 87 years, 25% men). They had on average 6 diagnoses and used 9 daily medications. Of the 83 patients, 61 (75%) had grip strength indicating sarcopenia, 27 (33%) impaired mobility, and 69 (83%) an impaired TMT-A score. Median amount of home nursing per week was 3.6 h (interquartile range 2.6 to 23.4). Fulfilment of pre-specified needs was >60% for skin and wound care in patients with skin diseases, observation of blood glucose in patients taking antidiabetic drugs, and in supporting food intake in patients with eating difficulties. Most other needs as defined by the consensus group were fulfilled in <10% of the patients. Conclusions: We identified a very frail group of home-dwelling patients. For this group, resources for home nursing should probably be used in a more flexible and pro-active way to aim for preserving functional status, minimize symptom burden, and prevent avoidable hospitalisations.

“…A proper TFD method is the one which is capable of emphasizing the non-stationarities of the given signal which, in turn, gives the system highest discriminative power to correctly discriminate between different cases in the population under consideration. In this study we use smoothed Wigner-Ville distribution (SWVD) as it is capable of reducing the cross-term affection while it provides good resolution [ 31 , 32 ]. SWVD is a variant method which incorporates smoothing by independent windows in time and frequency, namely

The wide spread usage of wearable sensors such as in smart watches has provided continuous access to valuable user generated data such as human motion that could be used to identify an individual based on his/her motion patterns such as, gait. Several methods have been suggested to extract various heuristic and high-level features from gait motion data to identify discriminative gait signatures and distinguish the target individual from others. However, the manual and hand crafted feature extraction is error prone and subjective. Furthermore, the motion data collected from inertial sensors have complex structure and the detachment between manual feature extraction module and the predictive learning models might limit the generalization capabilities. In this paper, we propose a novel approach for human gait identification using time-frequency (TF) expansion of human gait cycles in order to capture joint 2 dimensional (2D) spectral and temporal patterns of gait cycles. Then, we design a deep convolutional neural network (DCNN) learning to extract discriminative features from the 2D expanded gait cycles and jointly optimize the identification model and the spectro-temporal features in a discriminative fashion. We collect raw motion data from five inertial sensors placed at the chest, lower-back, right hand wrist, right knee, and right ankle of each human subject synchronously in order to investigate the impact of sensor location on the gait identification performance. We then present two methods for early (input level) and late (decision score level) multi-sensor fusion to improve the gait identification generalization performance. We specifically propose the minimum error score fusion (MESF) method that discriminatively learns the linear fusion weights of individual DCNN scores at the decision level by minimizing the error rate on the training data in an iterative manner. 10 subjects participated in this study and hence, the problem is a 10-class identification task. Based on our experimental results, 91% subject identification accuracy was achieved using the best individual IMU and 2DTF-DCNN. We then investigated our proposed early and late sensor fusion approaches, which improved the gait identification accuracy of the system to 93.36% and 97.06%, respectively.

Suppression of liquid slugs and phase separation through pipeline bends

This study examines the suppression of liquid slugs in the transport and separation of multiphase flows in pipelines. Two well-known slug control approaches are evaluated in this paper. The methods are employed to control and stabilize an undesired and unstable flow regime, optimize flow production, reduce operating costs, and in general, improve overall safety requirements of oil and gas pipelines. Unlike designs with an additional flowline to separate gas upstream, this study shows that active topside choking can suppress slugs and stabilize the system flowrates and pressures without the requirement of separation upstream of the topside valve. Careful choking is required to minimize production losses that can result from excess back pressure. A riser-based, gas-lift method reduces system instability and increases production. This study also reveals that negligible improvement in stability is achieved when large volumes of gas are injected. The system shifts into an annular flow regime when the injection is further increased. A large separator may be required to accommodate high gas volumes. This study shows that gas-lift not coordinated with choking is not effective for slug mitigation through pipeline bends. This paper also presents and discusses new non-dimensional correlations, including slug control inputs in the pipelines such as choke openings, based on new experimental data.
