Background: There is no consistent data on the mechanical properties of sheep intestine. OBJECTIVES: We performed a series of biaxial strain measurement experiments and extracted the constitutive model to describe the mechanical characteristics of the sheep intestinal tissue. METHODS: Eleven specimens were obtained freshly from sacrificed  sheep and the planar biaxial tests were performed on th...

Despite the success of elastography in grading hepatic fibrosis by stiffness related noninvasive markers the relationship between viscoelastic constants in the liver and tissue structure remains unclear. We therefore studied the mechanical properties of 16 human liver specimens with different degrees of fibrosis, inflammation and steatosis by wideband magnetic resonance elastography (MRE) and s...

The paper presents our experiences with the phone transi tion acoustical models The phone transition models were compared to the traditional context dependent phone models We put special atten tion on the speech signal segmentation analysis to provide a better in sight into certain segmentation e ects when using the di erent acoustical models Experiments with the HMM based models were performed...

Room acoustic design is an iterative process. Computer aided acoustical modelling is an efficient instrument to verify the design. The aim of this paper is to show the design process of a Hungarian concert hall. We have prepared the model of the hall at each step of the iteration. We have performed analyses with a ray-tracing based software, determined impulse responses at several receiver poin...

The nonlinear mechanical behavior of tissues that undergo large deformations, e.g. the breast, is characterized by hyperelastic parameters. These parameters take into account both types of nonlinearities: tissue intrinsic nonlinearity and geometric nonlinearity. Elastography technique capable of tissue hyperelastic parameter reconstruction has important clinical applications such as cancer diag...

Acoustical coupling between architectural spaces can be implemented by sliding or hinged doors. This study compares the effects of these variable coupling area designs on the sound field using temporal energy decay curve analysis. Varying the aperture size alters the multi-slope decay curve properties such as the decay rate of each slope and their point of intersection (time and level). A predi...
