Thermal testing of the STAR forward GEM tracker disks
In my thesis project, I worked on the Thermal Model for the FGT detector. The purpose of this thermal model is to simulate the cooling system for the electronics of the FGT. In this thesis report, I go over the construction of the model disks for the thermal model and the measurements I made on one …

Multi-resonant converters as photovoltaic module integrated maximum power point tracker
Module-integrated photovoltaic (PV) systems show high robustness against mismatching of the PV-generator, e.g. reasoned by partial shading. Thus, the surface potential for PV can be increased by the unevenly irradiated surfaces using module-integrated PV. Consequently, the important, already sealed …

D meson reconstruction at star using the silicon vertex tracker (svt)
<p>At the Relativistic Heavy Ion Collider a hot and dense matter is produced in Au+Au collisions at sqrt(sNN) = 200 GeV/c. This matter exhibits features of a new deconfined partonic matter, called the Quark-Gluon Plasma. Charm quarks are expected to be produced predominately from the initial gluon …
