Improved embedded beam elements for the modelling of piles
Engin, H. K.; Septanika, E. G.; Brinkgreve, R. B. J. (2007-04-27)
The embedded pile model is developed in Plaxis 3D Foundation Beta Version, to describe the pile-soil interaction in a foundation and to provide a numerical model for describing non-linear behaviour of the pile-soil interaction. In the present approach, the pile is considered as a beam element which can cross the soil at any place with any arbitrary orientation. The interaction between the pile and the surrounding soil at the pile shaft is described by means of embedded interface elements. At the pile tip, t...
Improved SIFT matching for image pairs with scale difference
BAŞTANLAR, YALIN; Temizel, Alptekin; Yardimci, Y. (2010-03-04)
When directly applied to images with different scales, scale invariant feature transform (SIFT) matching performance decreases significantly. In this reported work, this phenomenon is demonstrated and a simple method to increase the performance of SIFT matching is proposed. The proposed method includes preprocessing the images before matching and is compared to previously proposed solutions which only eliminate false matches.
Improved torque and speed control performance in a vector-controlled PWM-VSI fed surface-mounted pmsm drive with conventional P-I controllers
Büyükkeleş, Ümit; Ersak, Aydın; Department of Electrical and Electronics Engineering (2012)
In this thesis, high performance torque and speed control for a surface-mounted permanent magnet synchronous machine (PMSM) is designed, simulated and implemented. A three-phase two-level pulse width modulation voltage-source inverter (PWM-VSI) with power MOSFETs is used to feed the PMSM. The study has three objectives. The first is to compensate the voltage disturbance caused by nonideal characteristics of the voltage-source inverter (VSI). The second is to decouple the coupled variables in the synchronous...
Improved clock synchronization algorithms for the Controller Area Network (CAN)
Akpinar, Murat; Schmidt, Klaus Verner; Schmidt, Şenan Ece (2019-01-01)
Safety-critical in-vehicle applications require an accurate global time in order to coordinate their actions. Although Controller Area Network (CAN) is the most widely used in-vehicle communication bus, it does not support synchronized clocks. Hence, the realization of clock synchronization on CAN is highly relevant. This paper develops two new ideas for the clock synchronization on CAN. The first contribution is a new software-based algorithm based on periodic reference messages. Different from existing al...
Improved contact resistivity methods based on Cox-Strack and 4 point probe
Tsoi, Konstantin; Yerci, Selçuk; Department of Electrical and Electronics Engineering (2021-6)
Contact resistivity (c) of metal-semiconductor or conductive layer-semiconductor in the solar cells can limit their performance if not treated with care. It is, therefore, of great importance to be able to accurately measure rc for its optimization purposes. Many methodologies have been developed for this purpose. In this thesis, various methods for extracting rc are investigated. Namely, Transfer Length, Cox and Strack, four-point probe methods are discussed in detail. Cox and Strack and four-point probe ...
