За останні роки значно розширилась номенклатура сенсорів і галузі їх застосування, підвищились ефективність і точність вимірювання. Для задоволення постійно зростаючих потреб cучасної електроніки потрібні високочутливі швидкодіючі сенсори, функціональні в складних умовах експлуатації: у широких температурних інтервалах, магнітних полях, а також в умовах деформації, ударних і вібраційних навантажень.

Abstract:

A torque transducer or a torque sensor is a device for measuring and recording the torque on a rotating system. Torque transducers usually employ strain gauges to measure the torsional moment applied to a rotating shaft.It is to be noted that for an ideal torque transducer, it should measure only the strain that is caused by a torque. Strain due to bending load should be compensated as per the Wheatstone bridge arrangement. However, because of geometrical tolerances and assembly errors, the compensation doesn’t occur and the measured strain is a resultant of bending loads and axial loads which

The experimental results of electrophysical properties of granular film alloys based on Fe and Ag or Au are presented. It is established that the value of the temperature coefficient of resistance depends on the total thickness of the samples and the concentration of magnetic component. The components concentration in the system is shown to affect the formation of the solid solution and the granular film alloy. The optimal concentration value of Fe, in which the thermally stable solid solution forms, is 45 at. %.

Abstract:

In dense cities, the interactions between all structures, from tall skyscrapers to complex underground tunnel systems, need to be carefully analysed as soon as a new project is considered. This is necessary because of the stress changes in the soil induced by each new construction. Demolishing a building could cause heave at the base of the excavation, deflections in supporting structures and settlements of the surroundings. The behaviour can be modelled in order to predict how large the deformations will be. This thesis investigates the effectiveness of such models. This is done through the a

Abstract:

The strain rate dependent behaviour of fine grained soils is an important aspect of geotechnical engineering. During dynamic or rapid events such as earthquakes and rapid pile testing, a fine grained soil will display significantly different behaviour than may be observed over the long life span of a structure. There is currently little understanding of the factors which influence the behaviour of fine grained soils during dynamic events (extremely high strain rates), making their response difficult to predict. This research investigates the behaviour of fine grained soils subjected to a wide

There is no established method of measuring load accurately in a threaded connection at working temperatures exceeding 500°C.

High-entropy alloys (HEAs) that demonstrate excellent mechanical properties over steel-based alloys are not exempt from the common dilemma of strength–ductility trade-off, which limits their potential applications.

Two gradient profiles—a thin gradient layer with an undeformed core and a fully deformed structure—are introduced by adjusting the processing parameters.

Abstract:

The geotechnical community has since decades been acquainted with the use of statistical approach for design optimizations. This has been approved as an operational method by many practitioners in the field but is yet to see a major full-scale breakthrough and acceptance in practice. The advantage of quantifying the many different sources of uncertainties in a design is already a fairly acknowledged method and is in this report expanded for the use in the case of road embankments founded on soft soil improved by lime-cement columns. Statistical approach was adopted with practice of reliability

Abstract:

Colonoscopy provides a minimally invasive tool for examining and treating the colon without surgery, but current endoscope designs still cause a degree of pain and injury to the colon wall. The most common colonoscopies are long tubes inserted through the rectum, with locomotion actuators, fiber optic lights, cameras, and biopsy tools on the distal end. The stiffness required to support these tools makes it difficult for the scopes to navigate the twisted path of the colon without damaging the inside wall of the colon or distorting its shape. In addition, little is known about how sharp and fo

Abstract:

In the process of hot rolling is roll surface thermo-mechanically stressed. To define lifetime of roll or to increase it by change of thermal mode, temperatures and forces acting on this roll need to be known. For this purpose should be used sensors, that are placed near by surface of roll. Aim of the first part of diploma thesis is to debug 2D computing model (MKP) to achieve the match of temperature graphs with experimentally measured values, which was recorded by temperature sensors in real process of rolling. In the second part the same temperature boundary conditions are applied on 3D mod

Abstract:

As a part of vital infrastructure and transportation network, bridge structures must function safely at all times. Bridges are designed to have a long life span. At any point in time, however, some bridges are aged. The ageing of bridge structures, given the rapidly growing demand of heavy and fast inter-city passages and continuous increase of freight transportation, would require diligence on bridge owners to ensure that the infrastructure is healthy at reasonable cost. In recent decades, a new technique, structural health monitoring (SHM), has emerged to meet this challenge. In this new eng

Abstract:

Modéliser la localisation de la déformation dans les géomatériaux de manière objective nécessite l'utilisation de méthodes capables de régulariser le problème aux limites en introduisant une longueur caractéristique. Dans le cadre de ce travail de thèse, nous avons choisis d'utiliser les milieux à microstructures de types second gradient. Une question, alors se pose quant à l'identification des paramètres constitutifs qui interviennent dans la formulation de ces milieux. L'objectif de cette thèse est de mettre en place une méthode d'identification d'une loi de comportement enrichie de type sec

Abstract:

Under-platform damper is a device used in turbo engines to attenuate forced vibration amplitude and prevent high cycle fatigue of turbine blades, which are caused by hot gas flow and the vibration of engine rotor. The device itself is a piece of metal and during service it is loaded by centrifugal force against the platform underside of two adjacent blades. The relative movement of the blade platforms produces possible slip on the damper surfaces that dissipates the vibration energy through heat induced by friction. Although the damper is a simple device, it is difficult to predict and optim

Abstract:

A eficácia de métodos convencionais de transmissão, utilizados para medir absorção de materiais altamente transparentes, é geralmente limitada pela reflexão e espalhamento de luz. A espectroscopia de Lente Térmica, por outro lado, não é sensível a esses fenômenos, e tem sido amplamente usada na determinação de baixas absorções ópticas. Neste trabalho, estudamos uma configuração de Lente Térmica de duplo feixe (onda contínua cw), desenvolvida recentemente, e suas aplicações. Essa configuração otimiza a técnica de Lente Térmica, e aumenta significativamente a sensibilidade de medida. Foram real
