Stochastic Analysis of Time-Difference and Doppler Estimates for Audio Signals

Pairwise comparison of sound and radio signals can be used to estimate the distance between two units that send and receive signals. In a similar way it is possible to estimate differences of distances by correlating two received signals. There are essentially two groups of such methods, namely methods that are robust to noise and reverberation, but give limited precision and sub-sample refinement

Hardware-Conscious Wireless Communication System Design

The work at hand is a selection of topics in efficient wireless communication system design, with topics logically divided into two groups.One group can be described as hardware designs conscious of their possibilities and limitations. In other words, it is about hardware that chooses its configuration and properties depending on the performance that needs to be delivered and the influence of exte

Establishment of Melanoma Tumor Xenograft Using Single Cell Line Suspension and Co-injection of Patient-Derived T Cells in Immune-Deficient NSG Mice

When primary tumor cells are grown in vitro, they are exposed to an environment that is vastly different from the tumor environment they originate from. The in vitro environment can lack the three-dimensional structure of the tumor, other cell types present within the tumor microenvironment, and important growth factors. Humanized mouse models allow researchers to study primary tumor cells in a mo

The “black-and-white mural” in Polytechneio : Meaning-making, Materiality, and Heritagization of Contemporary Street Art in Athens

The campus of the National Metsovian Polytechnic in central Athens has been a signi cant cornerstone in the socio-political landscape of the city. Within the history of modern Greece, Polytechneio is regarded as a symbol of resistance against the Greek military dictatorship (junta) in 1973. In March 2015 and during times of austerity politics, the west façades of the Polytechneio were covered by a

Reaktorinneslutningarnas respons vid höga inre tryck och reducerad förspänning

The concrete structure of a reactor containment is pre-stressed with tendonsplaced in ducts. In some reactor containments, these ducts are injected withcement grout after pre-stressing. The cement grout protects the tendonsagainst corrosion and has the potential to redistribute the stresses in a tendon in the case of wire failure. The disadvantage of injected ducts is that the tendons pre-stressin

Europeanization in Sweden : Opportunities and Challenges for Civil Society Organizations

Notwithstanding its many successes since 1945, the project of European integration currently faces major difficulties, from financial crises and mass immigration to the impending departure of the UK from the European Union. At the same time, these challenges have spurred civil society organizations within and across Europe, revealing a shared public sphere in which citizens can mobilize around ref
