This paper introduces a new metamorphic parallel mechanism consisting of four reconfigurable rTPS limbs. Based on the reconfigurability of the reconfigurable Hooke (rT) joint, the rTPS limb has two phases while in one phase the limb has no constraint to the platform, in the other it constrains the spherical joint center to lie on a plane. This results in the mechanism to have ability of reconfi...

The aim of this study was to test the target impact constraint hypothesis of the one-target advantage. The one-target advantage phenomenon reflects the finding that movements to a single target show shorter movement times than similar movements followed by a second movement toward a second target. The target impact constraint hypothesis attributes this phenomenon to differences in passive decel...

We develop a module-based framework for constraint modeling where it is possible to combine different constraint modeling languages and exploit their strengths in a flexible way. In the framework a constraint model consists of modules with clear input/output interfaces. When combining modules, apart from the interface, a module is a black box whose internals are invisible to the outside world. ...

Geometric constraints are imperative components of many dynamic simulation systems to effectively control the behavior of simulated objects. In this paper we present an improved first-order implicit constraint enforcement scheme to achieve improved accuracy without significant computational burden. Our improved implicit constraint enforcement technique is seamlessly integrated into a dynamic si...

The aims of the study were to determine the impact of temporomandibular disorders (TMD) on self-percieved oral health related quality of life (OHRQoL) and to compare OHRQoL of patients with TMD with a control group. A total of 81 TMD patients participated in a study group and 400 adults served as the control group. The mean OHIP summary scores were computed for all patients with the same diagno...

This paper presents an efficient algorithm for the parallel implementation of dynamics simulation and analysis of multi-flexible-body systems. This algorithm formulates and solves the nonlinear equations of motion for mechanical systems with interconnected flexible bodies subject to the limitations of modal superposition, and body substructuring, with arbitrarily large rotations and translation...

We consider probabilistically constrained problems, in which the multivariate random variables are located in the right-hand sides. The objective function is linear, and its optimization is subject to a set of linear constraints as well as a joint probabilistic constraint enforcing that the joint fulfillment of a system of linear inequalities with random right-hand side variables be above a pre...

A cadaver model was used to test the hypothesis that glenohumeral joint stability is independent of articular surface conformity after total shoulder arthroplasty. For the purposes of this study joint stability was defined as the minimum force required for joint dislocation. After arthroplasty components were implanted into fresh-frozen glenohumeral joints, specimens were mounted on a load fram...

We propose coupled generative adversarial network (CoGAN) for learning a joint distribution of multi-domain images. In contrast to the existing approaches, which require tuples of corresponding images in different domains in the training set, CoGAN can learn a joint distribution without any tuple of corresponding images. It can learn a joint distribution with just samples drawn from the margina...

Background and Aim: The reduction of temporomandibular joint disorders (TMD) is one of the most significant concerns in dentistry. In contrast to initial treatments, such as pharmacotherapy and physiotherapy, which act as temporary tranquilizers, growth factors have shown promising results in the stimulation of cell division. Given the limited research on the positive impact of platelet-rich pl...
