Abstract:
I en kantviksmaskin som används för plåtbockning sker oönskade deformationer i mekanismen som klämmer fast arbetsmaterialet. Risken finns att deformationerna gör så arbetsmaterialet flyttas och det kan påverka positionen för bockningen.Målet med studien var att mäta laster och deformationer i kantviksmaskinen och sammanställa mätdata för att jämföra med FEM-analyser av konstruktionen och till grund för framtida arbete med maskinen. Problemet undersöktes genom att utföra mätningar med LVDT-givare och en lastcell. Mätresultatet visade att det blev en förskjutning och vid fastklämningen av arbets

Abstract:
As is generally known, pressure-resistant solenoids for valves are used in hydraulics and pneumatics. These solenoids, for example, consist of a so-called pole tube with an integrated armature and a separate solenoid coil. Suitable displacement measuring systems are used in order to measure the armature´s as well as valve spool´s position constnatly; these ar directly mounted to the solenoid. Exeamples here are Hall Effect sensors or LVDT transducers. In case of lesser requirements, it is also possible to measure the valve spool´s position directly and in simplified manner.

Le fratture vertebrali sono tra le principali cause dell’incremento della mortalità. Queste sono dovute principalmente a traumi, tumori o particolari patologie metaboliche che colpiscono l’osso. Il tratto maggiormente interessato è quello toraco-lombare in quanto deve sopportare la maggior parte dei carichi. Risulta quindi necessario comprendere come la colonna vertebrale risponde ai carichi così da studiare e sviluppare nuovi protocolli e trattamenti per disordini del tratto spinale.

Abstract:
This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. In addition to that, exposure of the metal casting to higher contraction or expansion during the solidification might also be related to internal strain development in samples, which eventually leads to surface crack propagation in some types of steel alloys dur

Bone is a common site for metastases and spine represent the most frequent site. Lytic lesions are associated with the loss of bone tissue, which can compromise the mechanical competence of the vertebra, leading to spine instability. Rigid stabilization is a solution, but it is a complex surgery, that can be very critical for oncologic patients; on the other hand, an untreated metastasis can lead to mechanical failure of the bone, leading to pain, immobilization and in the worst case, paralysis.

Previously, conventional state estimation techniques have been used for state estimation in power systems. These conventional methods are based on steady state models. As a result of this, power system dynamics during disturbances or transient conditions are not adequately captured. This makes it challenging for operators in control centers to perform visual tracking of the system, proper fault diagnosis and even take adequate preemtive control measures to ensure system stability during voltage dips. Another challenge is that power systems are nonlinear in nature. There are multiple power comp

Abstract:
Our society increasingly relies on the transmission and reception of vast amounts of data using serial connections featuring ever-increasing bit rates. In imaging systems, for example, the frame rate achievable is often limited by the serial link between camera and host even when modern serial buses with the highest bit rates are used. This thesis documents a scalable embedded transceiver system with a bandwidth and interface standard that can be adapted to suit a particular application. This new approach for a real-time scalable embedded transceiver system is referred to as a Novel Reference

Abstract:
There are growing industrial demands for low-voltage supply and low-power consumption circuits and systems. This is especially true for very high integration level and very large scale integrated (VLSI) mixed-signal chips and system-on-a-chip. It is mainly due to the limited power dissipation within a small area and the costs related to the packaging and thermal management. In this research work, two low-voltage, low-power integrated circuits used for data communication systems are introduced. The first one is a high performance continuous-time linear phase filter with automatic frequency tuni

Abstract:
This master thesis will cover the prestudy, hardware selection, design and implementation of a PCI Express bridge in the M.2 form factor. The thesis subject was proposed by WISI Norden who wished to extend the functionality of their hardware using an M.2 module. The bridge fits an M-Key M.2 slot and has the dimensions 80x22 mm. It is able to communicate at speeds up to 8 Gb/s over PCI Express and 200 Mbit/s on any of the 20 LVDS/CMOS pins. The prestudy determined that an FPGA should be used and a Xilinx Artix-7 device was chosen. A PCB was designed that hosts the FPGA as well as any power, deb

This thesis deals with the possibility of using impedance cardiography for calculating cardiac output. Kubicek’s, Sramek‘s and Sramek-Bernstein‘s methods are discussed here. These methods were applied to a data set, obtained by measuring on subjects with implanted cardiostimulators. The subjects’ heart rate was being changed by the programing of cardiostimulators. Thanks to this procedure the measured data were not affected by artifacts, connected with the heart rate change caused by a body stress, or other influences.

Due to the current research needs and the lack of commercial multi-channel, multi-constellation GNSS receivers, a two-board solution has been developed so it can be mated with and take advantage of the processing power of the FPGA board branded as MicroZed. In order to achieve the proposed goals, an initial phase for assessing and updating the older design, building, and testing of SiGe modules (including both the electronics and casings) has been carried out.

Leaflet replacement in aortic valve repair (AVr) is associated with increased long-term repair failure. Hemodynamic performance and mechanical stress levels were investigated after porcine AVr with 5 types of clinically relevant replacement materials to ascertain which material(s) would be best suited for repair. Porcine aortic roots with intact aortic valves were placed in a left-heart simulator mounted with a high-speed camera for baseline valve assessment. Then, the non-coronary leaflet was excised and replaced with autologous porcine pericardium (APP), glutaraldehyde-fixed bovine pericard

Four different sets of coils are investigated in this research, and the length of the LVDT will be reduced to as small as 13mm. By passing the sensing signal through an amplification circuit, the sensing sensitivity is raised to 9.53 from 11.5mV/mm, and the optimal e

Both analog and digital techniques have been used in the design of LVDT signal conditioners. This thesis explores a novel digital design of LVDT signal conditioners. Instead of a sine wave, a square wave is used to excite the primary winding. The signal conditioner is applied to a Schaevitz E200 LVDT sensor, which has a linear ran
