Yayın A parallel implementation: Real space Green's function technique(Sage Publications, 2007-04) Onat, Berk; Durukanoğlu, Sondan; Dağ, HasanWe develop an MPI-based parallel algorithm to implement the real space Green's function technique for calculating the vibrational density of states corresponding to a solid. The Hamiltonian describing the interactions between the atoms within the system is obtained from the embedded atom method. The parallel implementation speeds up calculation by an order of magnitude. The parallel implementation details and results are presented in this paper.Yayın Data compression for smart grid infrastructure(Işık Üniversitesi, 2018-01-15) Sarı, Ege Münir; Güz, Ümit; Gürkan, Hakan; Işık Üniversitesi, Fen Bilimleri Enstitüsü, Elektronik Mühendisliği Yüksek Lisans ProgramıEmbedded systems, which work with large data sets, need larger memory and consume much more data traffc when compared to other IOT (Interne Of Things) devices. In this study, Human's Lossless Compression Algorithm is optimized and implemented on a Electric Meter Reader Modem (DR-502-DCL). Compression Algorithm used for storing the data which is measured by the electric meter. Huffman's Algorithm optimized for memory (RAM) on a multi-threaded embedded system. STM32F412 microcontroller and Winbond 128mbit embedded ash memory is used for this study. Compression ratio of %59 is reached with eliminating repetitive character groups.
