Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

Conventional image-motion based methods for structure from motion first compute optical flow, then solve the 3D parameters on epipolar constraint, and finally recover geometry of scene. However, errors in flow due to regularization can lead large structure. This paper investigates whether performance consistency be improved by avoiding estimation early stages structure-from-motion pipeline, it ...

The effects of advancement of the tibial tuberosity by inserting bony wedges was studied on cadaveric specimens of the knee. The geometry, the contact areas and the forces acting on the patellofemoral joint were investigated, and the forces acting on the tibiofemoral compartment were calculated. A 1 cm advancement was found to be optimal in reducing the high patellofemoral joint forces occurrin...

Joint parameter identification is a key problem in the modeling of assembled complex structural. Dynamic behavior of mechanical joints may be with random feature due to the stochastic properties of preload, joint geometry, contact surface and its finishes, etc. A procedure for stochastic mechanical joint identification based on a novel model updating technique combined with probabilistic approa...

Ghumah Baghi is the vernacular architecture of Basemah highland, South Sumatra, Indonesia with distinctive wooden joints. Wood joint categories are divided based on geometry and arrangement, form, position, direction, move or no move, assembly, flush not flush, additional reinforcement, component change, resistance to loads. The problem this study was: what types wood joints were used in constr...

The Development and Evaluation of a 3-Dimensional, Image-Based, Patient-Specific, Dynamic Model of the Hindfoot Carl William Imhauser Sorin Siegler, Ph.D. This study developed subject-specific, three-dimensional dynamic hindfoot models (1 in vivo, 1 in vitro) using 3D stress MRI data. Each model’s ability to capture mechanical phenomena including those of the healthy hindfoot and the hindfoot w...

In the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. In 2-D analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...

In this paper experimentally, the friction-stir welding of the polypropylene sheets with 40% glass fiber has been investigated. Comparison to other welding methods, the strength of the joint is the most important feature in this process. Many parameters such as tool geometry, rotational speed, linear velocity, and tilt angle are very important as input parameters in this type of welding. Theref...
