objectives: the purpose of this study was to compare the outcomes of immediate and delayed rehabilitation of edentulous jaws by means of two straight and two tilted implants after one year of function. materials and methods: thirty consecutive patients (16 males, 14 females) were enrolled in this study. two anterior straight and two posterior tilted implants were placed in each patient. accordi...

1 We present a method to analytically compute the light distribution of triangles directly in frequency space. This allows for fast evaluation, shading and propagation of light from 3D mesh objects using angular spectrum methods. The algorithm complexity is only dependant on the hologram resolution and the polygon count of the 3D model. In contrast to other polygon based computer generated holo...

We consider the dynamics of a thin liquid film in the attractive substrate potential and under the action of a longitudinal or a tilted vibration. Using a multiscale technique we split the film motion into the oscillatory and the averaged parts. The frequency of the vibration is assumed high enough for the inertial effects to become essential for the oscillatory motion. Applying the lubrication...

Transfemoral amputees often report that walking on tilted pavements or on terrain with the prosthesis on the side of higher elevation is quite strenuous. This study investigates the energy expenditure of transfemoral amputees (n = 8) on a motorized treadmill, simulating different strenuous outdoor walking conditions. Oxygen uptake at self-selected speed of gait was measured during walking at th...

We consider the tilted-hexatic Hamiltonian on the fluctuating membranes. A renormalization-group analysis leads us to find three critical regions; two correspond to the strong coupling regimes of the gradient cross coupling where we find the (anti-)locked tilted-hexatic to liquid phase transition, the other to the weak coupling regime where we find four phases; the unlocked tiltedhexatic phase,...

The design and fabrication of a Micro-electromechanical Systems (MEMS)-based tilted microcoil on a polyimide capillary are reported in this paper, proposed for an electromagnetically-driven single-fiber endoscope scanner application. The parameters of the tilted microcoil were optimized by simulation. It is proved that the largest driving force could be achieved when the tilt-angle, the pitch a...
