Fall accidents are a frequent problem with the elderly and lead to severe injuries and/or could have a lethal ending. To prevent these potential deaths the nursing personnel visits the elderly on a regular basis. This has an enormous influence on the mental and physical capabilities of the nursing personnel. In combination with the ever-growing presence of Internet of Things (IoT) applications, this paper proposes a low-power wireless fall ...

Due to the ever growing population of elderly people, there is a dramatic increase in fall accidents. Currently, multiple ideas exist to prevent the elderly from falling, by means of technology or individualised fall prevention training programs. Most of them are costly, difficult to implement or less used by the elderly, and they do not deliver the required results. Furthermore, the increasingly older population will also impact the workload of ...

We examine the evidence for the claim of an 'ontological turn' in science and technology studies (STS). Despite an increase in references to 'ontology' in STS since 1989, we show that there has not so much been an ontological turn as multiple discussions deploying the language of ontology, consisting of many small movements that have changed the landscape within STS and beyond. These movements do not point to a shared STS-wide understanding of ...

Time waveform replication (TWR) is commonly used as control strategy to impose a given force (or displacement) target during fatigue testing. TWR belongs to the class of (linear) Iterative Learning Control strategies, which in general works well for systems with an approximately linear behavior. Larger errors occur when the nonlinear effects are more pronounced. In this contribution the TWR approach will be revisited taking into account the fact ...

OBJECTIVE: To understand the differences of step and turn parameters between freezers and non-freezers during turning and determine the influence of turn angle and turn characteristics on freezing of gait. DATA SOURCES: PubMed and Web of Science were searched from the earliest data available to August 2017. STUDY SELECTION: Case-control studies that examined the differences in turning while walking between freezers and non-freezers were ...

The Quai des Trois Fontaines is a berthing area in Chooz, France, which was designed for 80 m long vessels (CEMT Class IV) plying the River Meuse. A turning basin is located in front of the Quai des Trois Fontaines to allow vessels to turn before loading at the quay. Real time simulations on a dedicated inland ship manoeuvring simulator at Flanders Hydraulics Research were carried out with experienced skippers to study how the safety of the ...

Background: Despite the strong relationship between freezing of gait (FOG) and turning in Parkinson's disease (PD), few studies have addressed specific postural characteristics during turning that might contribute to freezing. Methods: Thirty participants with PD (16 freezers, 14 non-freezers) (all tested OFF medication) and 14 healthy controls walked 5 meters and turned 180 degrees in a 3D gait laboratory. COM behavior was analyzed during four ...

Background A life course approach recognizes the role of turning points in adding twists and turns in individuals' addiction recovery processes. The notion of certain key life events that trigger turning point experiences offers a valuable theoretical construct for understanding processes of change. The current study aimed to identify turning points and assess the role of contextual dynamics in generating long-term changes, based on lived ...
