Elimination of Non-Novel Segments at Multi-Scale for Few-Shot Segmentation
Kayabasi, Alper; Tufekci, Gulin; Ulusoy, İlkay (2023-01-01)
Few-shot segmentation aims to devise a generalizing model that segments query images from unseen classes during training with the guidance of a few support images whose class tally with the class of the query. There exist two domain-specific problems mentioned in the previous works, namely spatial inconsistency and bias towards seen classes. Taking the former problem into account, our method compares the support feature map with the query feature map at multi scales to become scale-agnostic. As a solution t...
Elimination of Coupling Transformer Core Saturation in Cascaded Multilevel Converter-Based T-STATCOM Systems
Gercek, Cem Ozgur; Ermiş, Muammer (2014-12-01)
This paper deals with coupling transformer core saturation problem in cascaded multilevel converter (CMC) based transmission-type static synchronous compensator (T-STATCOM) systems. The effects of nonlinear characteristics of the coupling transformer and CMCs on the core saturation phenomenon are investigated, and the associated mechanisms are described. In order to prevent the transformer core from being saturated, dc current components in the coupling transformer secondary lines are eliminated by modulati...
Elimination of transformer core saturation in cascaded multilevel converter based T-STATCOM systems
Gerçek, Cem Özgür; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2014)
This research work is devoted to the description of coupling transformer core saturation phenomenon and its elimination by modulated firing algorithms in Cascaded Multilevel Converter (CMC) based T-STATCOM systems. Transmission- type Static Synchronous Compensator (T-STATCOM) is connected to the transmission voltage level (≥110kV) via a coupling transformer. The coupling transformer may be an existing Medium Voltage (MV) to High Voltage (HV) or Extra High Voltage (EHV), or a specially designed transformer. ...
Destruction of the family of steady states in the planar problem of Darcy convection
Tsybulin, V. G.; Karasözen, Bülent (2008-08-25)
We consider natural convection of an incompressible fluid in a porous medium described by the planar Darcy equation. For some boundary conditions, Darcy problem may have non-unique solutions in form of a continuous family of steady states. We are interested in the situation when these boundary conditions are violated. The resulting destruction of the family of steady states is studied via computer experiments based on a mimetic finite-difference approach. Convection in a rectangular enclosure is considered ...
Reduction of Effects of Noise on the Inverse Problem of Electrocardiography with Bayesian Estimation
Serinağaoğlu Doğrusöz, Yeşim; Svehlikova, J.; Coll-Font, J.; Good, W.; Dubois, R.; Van Dam, E.; Macleod, R.S. (2018-09-01)
To overcome the ill-posed nature of the inverse problem of electrocardiography (ECG) and stabilize the solutions, regularization is used. Despite several studies on noise, effect of prefiltering of ECG signals on the regularized inverse solutions has not been explored. We used Bayesian estimation for solving the inverse ECG problem with and without applying various prefiltering methods, and evaluated our results using experimental data that came from a Langendorff-perfused pig heart suspended in a human-sha...
