The Fundament of the Fundaments? Family, Rights and Federalism in the EU Charter and EU Law
- 2024
-
Ingår i: The Family in EU Law. - 9781009498838
-
Bokkapitel (refereegranskat)abstract
- This chapter begins by explaining that family rights have been protected under EU law long before the adoption of the Charter. In particular, the chapter argues that the Court of Justice of the EU consolidated the protection of family life through a free movementrationale, guided by the need to eliminate obstacles to the exercise of the fundamental freedoms guaranteed by the Treaty. The chapter then focuses on investigating how family rights are protected under EU law today. The authors first analyse the horizontal provisions of the EU Charter of Fundamental Rights and how they can affect both the extent of protection and the substance of family rights. Subsequently, they look at how family rights have appeared in the Court’s case law. Finally, the authors consider the interaction of family rights with the EU citizenship provisions. Exploring the connection between fundamental rights, free movement and EU citizenship, the chapter concludes by signalling the timid use of Charter provisions to advance the protection of family life.

Improving OpenMP Productivity with Data Locality Optimizations and High-resolution Performance Analysis
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The combination of high-performance parallel programming and multi-core processors is the dominant approach to meet the ever increasing demand for computing performance today. The thesis is centered around OpenMP, a popular parallel programming API standard that enables programmers to quickly get started with writing parallel programs. However, in contrast to the quickness of getting started, writing high-performance OpenMP programs requires high effort and saps productivity.Part of the reason for impeded productivity is OpenMP’s lack of abstractions and guidance to exploit the strong architectural locality exhibited in NUMA systems and manycore processors. The thesis contributes with data distribution abstractions that enable programmers to distribute data portably in NUMA systems and manycore processors without being aware of low-level system topology details. Data distribution abstractions are supported by the runtime system and leveraged by the second contribution of the thesis – an architecture-specific locality-aware scheduling policy that reduces data access latencies incurred by tasks, allowing programmers to obtain with minimal effort upto 69% improved performance for scientific programs compared to state-of-the-art work-stealing scheduling.Another reason for reduced programmer productivity is the poor support extended by OpenMP performance analysis tools to visualize, understand, and resolve problems at the level of grains– task and parallel for-loop chunk instances. The thesis contributes with a cost-effective and automatic method to extensively profile and visualize grains. Grain properties and hardware performance are profiled at event notifications from the runtime system with less than 2.5% overheads and visualized using a new method called theGrain Graph. The grain graph shows the program structure that unfolded during execution and highlights problems such as low parallelism, work inflation, and poor parallelization benefit directly at the grain level with precise links to problem areas in source code. The thesis demonstrates that grain graphs can quickly reveal performance problems that are difficult to detect and characterize in fine detail using existing tools in standard programs from SPEC OMP 2012, Parsec 3.0 and Barcelona OpenMP Tasks Suite (BOTS). Grain profiles are also applied to study the input sensitivity and similarity of BOTS programs.All thesis contributions are assembled together to create an iterative performance analysis and optimization work-flow that enables programmers to achieve desired performance systematically and more quickly than what is possible using existing tools. This reduces pressure on experts and removes the need for tedious trial-and-error tuning, simplifying OpenMP performance analysis.

High Efficiency, Pt-free Photoelectrochemical Cells for Solar Hydrogen Generation based on “Giant” Quantum Dots
- 2016
-
Ingår i: Nano Energy. - : Elsevier BV. - 2211-2855. ; 27, s. 265-274
-
Tidskriftsartikel (refereegranskat)abstract
- Quantum dot (QD) sensitized TiO2 is considered as a highly promising photoanode material for photoelectrochemical (PEC) solar hydrogen production. However, due to its limited stability, the photoanode suffers from degradation of its long-term PEC performance. Here, we report the design and characterization of a high-efficiency and long-term stable Pt-free PEC cell. The photoanode is composed of a mesoporous TiO2 nanoparticle film sensitized with “giant” core@shell QDs for PEC solar hydrogen generation. The thick shell enhances light absorption in the visible range, increases the stability of the QDs and does not inhibit charge separation, injection and transport, needed for proper operation of the device. We prepared thin films of Cu2S nanoflakes through a simple and reproducible procedure, and used them as counter-electrodes replacing the standard Pt film, resulting in equivalent performances of the PEC cell. We obtained an unprecedented photocurrent density (~10 mA/cm2) for “giant” QDs based PEC devices (and corresponding H2 generation) and a very promising stability, indicating that the proposed cell architecture is a good candidate for long-term stable QD-based PEC solar hydrogen generation.

A Low-Reflection Absorptive Metasurface for Mid-IR Wavelengths
- 2020
-
Ingår i: 2020 14th International Congress on Artificial Materials for Novel Wave Phenomena, Metamaterials 2020.
-
Konferensbidrag (refereegranskat)abstract
- We report a design of an optical metasurface that selectively absorbs impinging electromagnetic waves in the desired wavelength while being fully transparent away from the resonance range. The proposed absorber consists of three-dimensional helical resonators that enable full control of light absorption due to the manipulation of the induced electric and magnetic dipole moments at the resonance. Full-wave simulations confirm the effectiveness of the proposed concept in the mid-infrared spectral range.
