This article discusses small sections of the Zakamskaya defensive line and New line, reasons for their construction, life in these fortifications main events associated with them. The prospect studying museumification monuments cultural heritage is also considered

In this study, an analytical model is developed to study crack breathing behavior under the effect of crack location and unbalance force. Crack breathing behavior is determined using effectual bending angle by studying the transient change in closed area of the crack. The status of the crack of a balanced shaft is symmetrical about shaft rotational angle and the duration of each crack status re...

external fluted feed rolls are commonly used in grain drills. the fluted feed roll meters a volume of seeds and does not singulate the seeds as do the precision planters; therefore, there will be inherent variation in the number of seeds delivered per unit of time. this research was conducted to investigate the effect of seed meter drive shaft and ground speeds and outlet positions in a grain d...

The function of our new marine hybrid turbocharger, which has a generator on its rotor shaft, is to supply electric power for consumption onboard a ship and to supercharge the ship’s diesel engine. The generator is driven by the turbocharger shaft, which is rotated by exhaust-gas energy; thus, the generator is an exhaust-heat-recovery device, and energy savings can be expected. A high-speed, hi...

In this paper we propose a robust approach for automatic 3d model acquisition of sewer shafts from survey videos. Images are captured by a specific camera setup which is composed of a downward-looking fisheye-lens camera while lowering it into the shaft. Additionally, an inertial sensor measures rotation around the viewing axis. Our approach is based on Structure from Motion adjusted to the con...

Background Hair is an ectodermal structure, and its formation is regulated by master genes important in embryology. Hair shaft consists of three major regions: the medulla, cortex and cuticle. Hair shaft abnormality will divide structural hair abnormalities into two broad categories - those associated with increased hair fragility and those not associated with increased hair fragility. We condu...

The degree of precision for positioning of adjustable rollers during pre-registering stage has direct influences on register precision of the entire printing. The paper puts forward control strategy of sliding mode variable structure-based electronic virtual line shafting based on the influences of low-speed preregister process of shaft-less drive printing press on register precision and the in...

torque, speed, and power as mechanical variables are associated with the functional performance of any rotating machinery. the real-time performance and the efficiency of a machine can be determined with on-line measurement of these parameters. in this investigation a rotary torque meter (transducer) was constructed from strain gauge sensors for measuring the torque of rotating shafts. the syst...

This paper presents stress and strain analysis of outer shaft shoulder (OSS) and inner shaft shoulder (ISS) of a new paddy harvesting head (PHH) using finite element method (FEM). Snapping grain unit is a part of this head, with OSS and ISS as its members. The analysis was performed using the ABAQUS software with Dynamics Explicit Solution Method. Eight-node block and four-node tetrahedral elem...
