This note presents a unified analysis of the recovery of simple objects from random linear measurements. When the linear functionals are Gaussian, we show that an s-sparse vector in R can be efficiently recovered from 2s log n measurements with high probability and a rank r, n×n matrix can be efficiently recovered from r(6n − 5r) measurements with high probability. For sparse vectors, this is w...

Slope rounding is discussed in the Roadside Design Guide as a practice that breaks the sharp edge in a highway cross section and the side slope. There have been past studies aimed at understanding the influence of slope rounding on vehicle trajectories for various slope conditions. These studies were conducted about twenty years ago and only looked at a small subset of vehicle types despite the...

Background Thoracic hump, shoulder imbalance, lumbar hump were known as trunk deformities associated with scoliosis bothering patients. In addition to these deformities, anterior chest hump (ACH) occurring at the distal end of the anterior chest wall on the convex side, may be another noteworthy problem. We evaluated how much patients with adolescent idiopathic scoliosis (AIS) were bothered by ...

The paper studies local convexity properties of digital curves. We locally define convex and concave parts from the slope of maximal digital straight segments and arithmetically characterize the smallest digital pattern required for checking convexity. Moreover, we introduce the concepts of digital edge and digital hull, a digital hull being a sequence of increasing or decreasing digital edges....

HYPOTHESIS Glenoid erosion and medial migration of the humeral head prosthesis have been observed after most types of shoulder arthroplasty. A method of measuring the change in humeral head position with time after shoulder prosthetic arthroplasty was applied it to 14 shoulders that underwent humeral hemiarthroplasty with concentric glenoid reaming. We hypothesized that the measurement techniqu...

objectives: the purpose of this study was to investigate the effect of 4-weeks rehabilitation, electrotherapy and kinesiotherapy programs on range of motion shoulder pain in men with idiopathic frozen shoulder. methods & materials: this was a semi experimental study on 18 patient (means±sd age 56.4±6.7 year, height 175.1±5.3 cm, weight 73.1±7.5 kg, history patient 9.2±5.1 month) who referred to...

Hillslopes have complex three-dimensional shapes that are characterized by their plan shape, profile curvature of surface and bedrock, and soil depth. To investigate the stability of complex hillslopes (with different slope curvatures and plan shapes), we combine the hillslopestorage Boussinesq (HSB) model with the infinite slope stability method. The HSB model is based on the continuity and Da...

This paper deals with the absolute stability analysis for uncertain time delay Lur’e systems that have time-varying delays and sector and slope restricted nonlinearities. New delaydependent stability criteria are derived via linear matrix inequality (LMI) formulation that can be easily solved by various optimization techniques. Sector bounds and slope bounds are employed to the Lyapunov–Krasovs...

Objectives: The purpose of this study was to investigate technique differences between expert and novice manual wheelchair users during over-ground wheelchair propulsion. Method: Seven experts (spinal cord injury level between T5 and L1) and six novices (non-wheelchair users) pushed a manual wheelchair over level ground, a 2.5% cross slope and up a 6.5% incline (7.2 m length) and 12% incline (1...
