Life of a Photon in X-ray Spectroscopy
This thesis summarizes the experimental work in which an ultrafastX-ray laser plasma source was combined with variousscalable direct detection schemes to test a novel approach forlab-based time-resolved X-ray absorption spectroscopy. A laserplasma source based on a water jet target was built and commissioned.X-ray and electron emissions of this source were characterizedwith various direct detectio

Sub-picosecond, table-top x-ray absorption spectroscopy using superconducting microcalorimeters
We present time-resolved X-ray absorption measurements of vanadium dioxide using ionizations radiation generated by a femtosecond pulsed laser source in combination with superconducting microcalorimeters capable of measuring energies of individual radiation quanta.
Temperature-dependent electronic and vibrational structure of the 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide room-temperature ionic liquid surface: a study with XPS, UPS, MIES, and HREELS.
The near-surface structure of the room-temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide has been investigated as a function of temperature between 100 and 620 K. We used a combination of photoelectron spectroscopies (XPS and UPS), metastable induced electron spectroscopy (MIES), and high-resolution electron energy loss spectroscopy (HREELS). The valence band a
Influence of hydrogen on nanocrystalline diamond surfaces investigated with HREELS and XPS
Interaction of Hydrogen and Oxygen with Nanocrystalline Diamond Surfaces
Nanocrystalline diamond films (NCD) are strong candidates for applications in a wide variety of fields. An important concern in all these applications is to understand the properties of variously prepared NCD surfaces. This contribution is focussed on the surface science study of hydrogen and oxygen containing NCD films using X-ray photoelectron spectroscopy (XPS) as well as high resolution electr
Taking snapshots of photosynthetic water oxidation using femtosecond X-ray diffraction and spectroscopy.
The dioxygen we breathe is formed by light-induced oxidation of water in photosystem II. O2 formation takes place at a catalytic manganese cluster within milliseconds after the photosystem II reaction centre is excited by three single-turnover flashes. Here we present combined X-ray emission spectra and diffraction data of 2-flash (2F) and 3-flash (3F) photosystem II samples, and of a transient 3F

Accessing On-chip Instruments Through the Life-time of Systems
The electronic systems we find in almost every product today are implemented using integrated circuits (ICs) mounted on printed circuit boards (PCBs). Developing electronic systems is a challenging task due to complexity and miniaturization. A single IC can contain billions of transistors, which are smaller than ever. As a result more Design-for-Test (DfT) features, so called instruments, are embe
Exact Methods for Multi-echelon Inventory Control : Incorporating Shipment Decisions and Detailed Demand Information
Recent advances in information technologies and an increased environmental awareness have altered the prerequisites for successful logistics. For companies operating on a global market, inventory control of distribution systems is often an essential part of their logistics planning. In this context, the research objective of this thesis is: To develop exact methods for stochastic inventory control

Desalination and Brine Discharge Case Study for PEAW in Oman
Desalination is an important method for producing drinking water and it has been a freshwater supply alternative for a long time. The water resources in the Gulf Cooperation Council (GCC) countries, are mostly depending on desalination as a major source of (>80 %) drinking water, while the rest comes from groundwater. The largest number of desalination project is located in the Gulf countries (Sau
Like a Garden of Flowers : A Study of the Formation of the 'Book' of Psalms
This is a study of the formation of the ‘Book’ of Psalms that attempts to provide answers to two fundamental questions: “how?” and “why?”. The first relates to the diachronic growth of the collection (how are these processes to be reconstructed, and on what grounds?), while the second relates to questions of purpose (to what end are psalms being juxtaposed in a collection?). Proceeding from a revi
A move to the local? : The relevance of a local welfare system approach
Fighting poverty and promoting active inclusion is a major challenge for most European welfare states. This chapter argues that much current welfare research has focused on national policies and systems despite most anti-poverty strategies are put into practice at local level. The chapter explores the local welfare system approach and maintains that it is important to study the role public and civ
