In this paper a special type of nonlinear marking specifications called stair generalized mutual exclusion constraints (stair-GMECs) is defined. A stair-GMEC can be represented by an inequality whose left-hand is a linear combination of floor functions. Stair-GMECs have a higher modeling power than classical GMECs and can model legal marking sets that cannot be defined by OR-AND GMECs. We propo...

Following total knee arthroplasty (TKA), physical therapists must evaluate patient readiness to safely begin stair-climbing. Physical therapists might find self-reported chair-rise ability useful in determining stair-climbing readiness of patients. We grouped 31 subjects who were at approximately 3.6 weeks post-TKA by chair-rise ability (group 1 = "Because of my knee, I can only rise from a cha...

Spatially organized clusters are basic structure for large-scale wireless sensor networks. A cluster is generally composed by a large amount of energy-limited low-tier nodes (LNs), which are managed by a powerful cluster head (CH). The low-tier nodes that are close to the cluster head generally become bottlenecks in data collection applications. Energy efficient scheduling is important for the ...

Most individuals with intellectual disabilities (ID) demonstrate problems in learning and movement coordination. Consequently, they usually have difficulties in activities such as standing, walking, and stair climbing. To monitor the physical impairments of these children, regular gross motor evaluation is crucial. Straight-line level walking is the most frequently used test of their mobility. ...

[Purpose] This study investigated the effect of stepper exercise with visual feedback on strength, walking, and stair climbing in stroke patients. [Subjects] Twenty-six stroke patients were divided randomly into the stepper exercise with visual feedback group (n = 13) or the stepper exercise group (n = 13). [Methods] Subjects in the experimental group received feedback through the mirror during...

BACKGROUND Loss of muscle strength exerts a considerable impact on the quality of life and mortality of older adults. The present household survey study measured body composition and muscle strength with the aim of analyzing the roles of low lean mass, low muscle strength and obesity in stair negotiation ability and the effect of comorbidities on the relationship between body composition and fu...

BACKGROUND The objective of this study was to assess the role of a symptom-limited stair climbing test in predicting postoperative cardiopulmonary complications in elderly candidates for lung resection. METHODS A consecutive series of 109 patients more than 70 years of age who underwent pulmonary lobectomy for lung carcinoma from January 2000 through May 2003 formed the prospective database o...

One of the current areas of research in robotics is in the development of robots which can interact with humans in performing a variety of tasks. In particular, there is a desire to enable robots to use objects as tools to perform tasks. For example, assembly tasks may require the robot to use a screwdriver to tighten screws or a hammer for nailing. In this project, I am concerned with the prob...
