This research is a study that discusses the comparison of results analysis calculation forces on wooden framework using Structure Analysis Program-2000 (SAP-2000) and method joint. The value each force vertical bars, horizontal tensile compression members at point will be calculated three spans with 7m, 9m, 11m. Comparison rod from two methods compared to see efficiency methods. From joint in c...

The study aims to substantiate the design and parameters of comb-forming device with elastic rods. basic principles methods classical mechanics, mathematical analysis statistics were used in this study. authors proposed a machine rods for sowing cotton on combs. main amount vertical load working body are justified by experimental studies. It is established that diameter 3 mm rod, number 64 piec...

The main purpose of the present paper is to compare two different kinds approaches in modeling deck a suspension bridge: first approach we look at as rectangular plate and second one beam for vertical deflections rod torsional deformations. Throughout this will refer model corresponding beam-rod model. In our discussion, observe that contains larger number elastic parameters if compared with is...

Purpose: To determine the influence of geometric parameters on most common elastic rod clip used in modern intermediate rail fastenings — B-shaped (such as reinforced concrete (RCR) and anchor fastening (ARF)) changes its stress-strain state. propose a further direction improving design clips fasteners to increase reliability structure. Methods: The article presents results multivariate modelin...

The main purpose of this study is to perform numerical simulation of nanofluids as the coolant in VVER-440 fuel rod bundle. The fuel rod bundle contains 60 fuel rods with length of 960 mm and 4 spacer grids. In VVER-440 fuel rod bundle the coolant fluid (water) is in high pressure and temperature condition. In the present Thermo-hydraulic simulation, water-AL2O3 nanofluids containing various vo...

In the primate retina, H1 horizontal cells form an electrically coupled network and receive convergent input from long- (L-) and middle- (M-) wavelength-sensitive cones. Using an in vitro preparation of the intact retina to record the light-evoked voltage responses of H1 cells, we systematically varied the L- and M-cone stimulus contrast and measured the relative L- and M-cone input strength fo...

Abstract In the paper, a new 3D energy harvesting system is provided. This work discussed Lagrange approach to derive differential equations of motion in case systems. An electromechanical consists mechanical resonator, piezoelectric transducer and electrical circuit with load resistor. A flexible slender rod clamped at bottom loaded by tip mass proposed as resonator. Moving space, it enables a...

The process of suppressing transverse vibrations an elastic rod spinning in a horizontal plane and fixed at one its ends is studied. It supposed that the spins around vertical axis constant angular velocity performs plane, are assumed small amplitude. Transverse performed under external mechanical action. Lateral described by displacement function considered rotating using classical beam model....

One of the central tasks in retinal neuroscience is to understand the circuitry of retinal neurons and how those connections are responsible for shaping the signals transmitted to the brain. Photons are detected in the retina by rod and cone photoreceptors, which convert that energy into an electrical signal, transmitting it to other retinal neurons, where it is processed and communicated to ce...
