free surface modeling plays an important role in some ocean structures design, especially in oscillating water column (owc) devices. boundary element method (bem) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. in this paper, bem was used for free surface modeling in owc chamber and out of it. linear kinematic and dynamic bo...

PURPOSE Muscarinic receptor signaling is involved in ocular development and implicated in myopia. The aims of this study were to identify the presence of muscarinic acetylcholine receptors (mAChRs) in normal ocular tissues of guinea pigs and to determine if ocular expression of mRNA and protein changes in guinea pigs with or without form-deprived myopia (FDM). METHODS One- to two-week-old gui...

When printing a plate (or dish) by an FDM 3D printer, the process normally requires support material, which causes several problems. This paper proposes a method for forming thin plates without using wasteful support material. This method requires several extraordinary parameter values when slicing plates. The experiments show that the plates can, for the most part, be successfully formed using...

Comparisons are made between the finite difference method (FDM) and the control volume formulation (CVF). An analysis of truncation errors for the two methods is presented. Some rules-of-thumb related to the accuracy of the methods are included. It is shown that the truncation error is the same for both methods when the boundary conditions are of the Dirichlet type, the system equations are lin...

Purpose To determine whether dopamine receptor D1 (D1R) signaling pathway activation by bright light (BL) in specific retinal neuronal cell types contributes to inhibiting form-deprivation myopia (FDM) in mice. Methods Mice (3-weeks old) were raised under either normal light (NL: 100-200 lux) or BL (2500-5000 lux) conditions with or without form deprivation. Refraction changes were evaluated ...

Obtaining diffusion coefficients from PFG NMR diffusion (a.k.a DOSY) data is, in the general case, an ill-posed problem. Numerous methods for processing such data have therefore been developed, each with different constraints and assumptions. The Regularized Resolvent Transform (RRT) is a proven and robust method for spectral inversion. In earlier papers RRT, albeit very slow, was argued to be ...

Moving objects detection is conducted in the sequential image of moving objects, which is favorable to detect, identify and analyze the moving objects. It has been applied in video surveillance, virtual reality, and advanced user interfaces. Based on existing research on the Frame Difference Method (FDM) and the Background Subtraction Method (BSM), considering the short time interval between ad...

We outline an important advance in the problem of obtaining a two-dimensional (2D) line list of the most prominent features in a 2D high-resolution NMR spectrum in the presence of noise, when using the Filter Diagonalization Method (FDM) to sidestep limitations of conventional FFT processing. Although respectable absorption-mode spectra have been obtained previously by the artifice of "averagin...

Fused Deposition modelling (FDM) technology is based on decomposition of 3-D computer models into thin cross sectional layers, followed by physically forming the layer and stacking them up layer by layer. FDM provide freedom to add material in the desired area and we are also able to create hollow region in certain portion of layer. In this way low weight with good strength single ply raw mater...

Background Secondary neuronal injury in the perihematomal edema is one of the major factors that lead to the high morbidity and mortality in primary intracerebral hemorrhage (ICH). Diffusion magnetic resonance imaging (MRI) has been applied in studying perihematomal injury in patients with ICH but with inconstant results. Because the perihematomal injury should be complex and heterogeneous, dif...
