The manual assessment of activities of daily living (ADLs) is a fundamental problem in elderly care. The use of miniature sensors placed in the environment or worn by a person has great potential in effective and unobtrusive long term monitoring and recognition of ADLs. This paper presents an effective and unobtrusive activity recognition system based on(More)
High-level and longer-term activity recognition has great potentials in areas such as medical diagnosis and human behavior modeling. So far however, activity recognition research has mostly focused on lowlevel and short-term activities. This paper therefore makes a first step towards recognition of high-level activities as they occur in daily life. For this(More)
This thesis investigates the use of wearable sensors to recognize human activity. The activity of the user is one example of context information – others include the user’s location or the state of his environment – which can help computer applications to adapt to the user depending on the situation. In this thesis we use wearable sensors – mainly(More)
OBJECTIVE To report the long-term results of our experience using cerebrospinal fluid drainage and distal aortic perfusion in descending thoracic and thoracoabdominal aortic repair. SUMMARY BACKGROUND DATA Repair of thoracoabdominal and thoracic aortic aneurysm by the traditional clamp-and-go technique results in a massive ischemic insult to several major(More)
BACKGROUND Although the incidence of patients presenting with concomitant colorectal cancer (CRC) and abdominal aortic aneurysm (AAA) is low, current treatment strategies in patients with both lesions remains controversial. Given recent advances in endovascular aortic aneurysm repair (EVAR), we sought to analyze the surgical outcomes of patients with(More)
BACKGROUND The benefit of distal aortic perfusion and cerebrospinal fluid drainage over the "clamp and sew" technique during repairs of the descending thoracic aorta is still being debated. The purpose of this report is to analyze our experience with regard to neurologic deficit (paraplegia and paraparesis) and mortality using the adjuncts of distal aortic(More)
BACKGROUND Neurologic deficit (paraparesis and paraplegia) after repair of the thoracic and thoracoabdominal aorta remains a devastating complication. The purpose of this study was to determine the effect of cerebrospinal fluid drainage and distal aortic perfusion upon neurologic outcome during repair of thoracic and thoracoabdominal aortic aneurysm (TAAA)(More)
BACKGROUND Rheolytic mechanical thrombectomy using the AngioJet catheter (Possis Medical, Minneapolis, MN) has been shown to be effective in the treatment of deep venous thrombosis (DVT). Additional infusion of thrombolytic agents via the device creates a novel treatment strategy of pharmacomechanical thrombectomy (PMT), which further enhances thrombectomy(More)
BACKGROUND Acute mesenteric ischemia (AMI) is associated with high morbidity and mortality due in part to its diagnostic difficulty and operative challenges. The purpose of this study was to review our experience of surgical management in patients with this condition and to identify variables associated with adverse outcomes following surgical(More)
