Investment in renewable energy sources for military purposes is to dramatically increase in the coming years due to tactical, geopolitical, economic and environmental reasons. Major military powers have started to explore various opportunities for alternative liquid fuels while small countries are facing multiple barriers. The Military of Lithuania has been chosen as a research object to reveal wh

Understanding of the environmental and climate processes Research at the department of Physical Geography and Ecosystem Science is mainly focused on interdisciplinary studies of how climate and environmental changes affect the function and composition of terrestrial ecosystems. The goal is to increase understanding of the processes that take place in the exchange between the biosphere and atmosphe

Researchers have measured superfluid helium’s full dispersion spectrum, explaining discrepancies in previous studies and constraining theories of superfluidity.

Isolated attosecond pulse (IAP) generation usually involves the use of short-medium gas cells operated at high pressures. In contrast, long-medium schemes at low pressures are commonly perceived as inherently unsuitable for IAP generation due to the nonlinear phenomena that challenge favourable phase-matching conditions. Here we provide clear experimental evidence on the generation of isolated ext

Monolayer molybdenum ditelluride (MoTe2) attracted intensive scientific interest due to the small energy difference between its semiconducting (1H) and semimetallic (1T’) phases. Understanding MoTe2 polymorphism phenomena and developing pathways to induce reversible phase transformations is of great scientific and practical importance to develop semiconductor-semimetal phase change devices. In thi

Single-layer molybdenum ditelluride (MoTe2) has attracted attention due to the smaller energy difference between the semiconducting (1H) and semimetallic (1T′) phases with respect to other two-dimensional transition metal dichalcogenides (TMDs). Understanding the phenomenon of polymorphism between these structural phases is of great fundamental and practical importance. In this paper, we report a

This survey concerns optimization problems arising in the design of survivable communication networks. It turns out that such problems can be modeled in a natural way as non-compact linear programming formulations based on multicommodity flow network models. These non-compact formulations involve an exponential number of path flow variables, and therefore require column generation to be solved to

This thesis concerns a sociological analysis on the role of generations in the processes of the construction of national identities, and long-distance nationalism in diasporic settings. The empirical case taken is a political generation of Kurds from Turkey who once arrived in Sweden as political refugees. The primary aim of the thesis is to study how national identities are constructed and maint

In a storage-ring free-electron laser (FEL), the onset and growth of intra-cavity power at the resonator wavelength can be naturally accompanied by coherent emission at higher harmonics. Contrary to what happens in singlepass linac-based devices, the electron beam is re-circulated in the storage ring and, while the microbunching becomes "thermalized" from turn to turn, the evolution of other bunch

We present a completely ab initio calculation of harmonic generation in xenon exposed to a strong laser field. The time-dependent Schrödinger equation for the atomic response and the propagation equation are numerically integrated yielding excellent agreement with experiment. The weaker variation with pump intensity of the induced dipole in the high-field regime leads to an enormous enhancement in

This paper deals with path-based linear programming formulations in survivable network design. In a recent survey we have investigated the complexity of the column generation problems for a large variety of protection and restoration mechanisms in a single or multiple link failure scenario, and classified them according to their structure. It turned out that all the considered column generation pr

Generally regarded as a sustainable country, Costa Rica faces the future challenge of maintaining their renewable energy performance amidst climate change impacts and the need to integrate intermittent renewables. This thesis explores the opportunities and barriers for Costa Rica to achieve 100% renewable electricity while maintaining energy security, despite its developing nation status. Through
