1. Programming Abstractions and Optimization Techniques for GPU-based Heterogeneous Systems
Sammanfattning : CPU/GPU heterogeneous systems have shown remarkable advantages in performance and energy consumption compared to homogeneous ones such as standard multi-core systems.Such heterogeneity represents one of the most promising trendsfor the near-future evolution of high performance computing hardware.

2. Validation of Several Nucleoside Tracers as Proliferation Markers
Sammanfattning : Positron emission tomography (PET) is a powerful method for in vivo characterization of tumor biochemistry and clinically has been used for diagnosing and grading of malignancy. A key element in oncology is proliferation potential, a feature that is assumed to be an important indicator of tumor growth. LÄS MER
3. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys
Sammanfattning : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

4. A study of wireless communications with reinforcement learning
Sammanfattning : The explosive proliferation of mobile users and wireless data traffic in recent years pose imminent challenges upon wireless system design. The trendfor wireless communications becoming more complicated, decentralized andintelligent is inevitable. LÄS MER
5. Time-resolved laser spectroscopic studies of atoms, ions and Molecules
Sammanfattning : Time-resolved laser spectroscopy has been performed to study the radiative properties of various microscopic systems. Using Laser-Induced Fluorescence (LIF) techniques, natural radiative lifetimes have been studied not only in neutral B, S, Ge, Ce, Pb, and in singly ionized V, Fe, Zr, Mo, La, Ce, Eu, Gd and Yb, but also in doubly ionized La, Ce, Pr, Eu, Er, Gd, Tm, Lu, and W.
