PURPOSE To report a novel method for measuring the vertical tilt angle of the optic nerve (ON) head and to investigate the associated factors. DESIGN Cross-sectional diagnostic study. METHODS One hundred and twelve normal, glaucomatous, and glaucoma suspect eyes (99 patients) were enrolled in this study. Subjects underwent a full eye examination, biometry, and spectral-domain optical cohere...

The paper is focused on an analysis and optimization of the rotary draw benging process to eliminate bent tube ovality by modification pressure bar geometry. bending realized WafiosCNC machine. A that for automotive application made 34MnB5 steel. Currently, after angle 120°, unacceptable occurs. Therefore, it necessary improve quality production thus prevent formation ovality. In this case, ge...

Submarine pipeline is a key part in the development of deep sea and ultra-deep oil gas. In order to reduce ovality pipes improve their compressive strength, two-roller continuous calibration (TRCC) process by compression proposed. A springback analysis compress bending carried out, an analytical model established, which predicts after provides theoretical basis for roller shape design parameter...

There are new chemical substances that increase the strength of washing products such as surfactants. However, these products are not biodegradable and can all be found in surface water, groundwater. Cationic surfactants are one of the pollutants of greatest danger to man is his environment. Therefore, we have determined some parameters of three cationic surfactants by molecular modeling, using...

Drilling is an hole making process in metal cutting operation performed by extrusion which finds wide application in various industries for manufacturing components using metals and non metals. This process is applied widely in assembly of components or elements, where processing challenges are severe issue such as to maintain surface integrity, ovality, machining time, Metal Removal Rate etc.,...

Structural colour in 3D-AAO metamaterials depends on the period between transversal channels, while hue is related with shape (ovality) of which waveform and etching time.

In this paper, we propose a noncircular-parallel factor (NC-PARAFAC) algorithm for two-dimensional direction of arrival (DOA) estimation of noncircular signals for acoustic vector-sensor array. The proposed algorithm enhances the angle estimation performance via utilizing the noncircularity of the signals, and it can be suitable for arbitrary array subjected to unknown locations and achieve aut...

The laser tube bending process (LTBP) is a thermal non-contact for tubes with less springback and thinning of the tube. In this paper, will be studied experimentally. length irradiation scheme are two main affecting parameters in LTBP process. For purpose, different samples according to schemes (Circular irradiating (CIS) axial (AIS)) lengths beam (from 4.7 28.2 mm) fabricated. angle laser-bent...

Quantitative structure – activity relationships were developed for the toxicity of 56 aliphatic esters to the protozoan ciliate Tetrahymena pyriformis. The toxicity was measured as A=Log(1/IGC50), where IGC50 is the concentration which inhibits a 50% growth of T. pyriformis. The ovality van der Waals descriptors of molecular shape, ΘiD, i=1,2,3 were used as predictor variables. They were calcul...
