Introducing PT-REX, the point-to-point TRend EXtractor

Surprising spectra of PT -symmetric point interactions

Spectra of the second derivative operators corresponding to the special PT -symmetric point interactions are studied. The results are partly the completion of those obtained in [1]. The particular PT -symmetric point interactions causing unusual spectral effects are investigated for the systems defined on a finite interval as well. The spectrum of this type of interactions is very far from the ...

Introducing k-point parallelism into VASP

a r t i c l e i n f o a b s t r a c t For many years ab initio electronic structure calculations based upon density functional theory have been one of the main application areas in high performance computing (HPC). Typically, the Kohn– Sham equations are solved by minimisation of the total energy functional, using a plane wave basis set for valence electrons and pseudopotentials to obviate the ...

fixed point property for banach algebras associated to locally compact groups

در این پایان نامه به بررسی خاصیت نقطه ثابت و خاصیت نقطه ثابت برای نیم گروههای برگشت پذیر چپ روی بعضی جبرهای باناخ از جمله جبر فوریه و جبر فوریه استیلتیس پرداخته شده است. برای مثال بیان شده است که اگر گروه یک گروه فشرده موضعی با همسایگی فشرده برای عنصر همانی که تحت درونریختی ها پایاست باشد آنگاه جبر فوریه و جبر فوریه استیلتیس دارای خاصیت نقطه ثابت برای نیم گروه های برگشت پذیر چپ است اگر و تنها ا...

C-REX: An Evolutionary Code Extractor for C

Software systems are continuously changing to adapt to customer’s evolving needs. However, the source code change process is not well understood. Source control systems record changes to the source code of a software system. These recorded details could be used to gain some insight into the evolutionary process followed by the source code. In this paper, we discuss C-REX, an evolutionary code e...
