Further exploitation of the spatial domain, as in Massive MIMO (MaMi) systems, is imperative to meet future communication requirements [1]. Up-scaling of conventional 4×4 small-scale MIMO implementations to MaMi is prohibitive in-terms of flexibility, as well as area and power cost. This work discloses a 1.1mm2 128×8 MaMi baseband chip, achieving up to 12dB array and 2× spatial multiplexing gains.
This thesis is dedicated to the design and analysis of superconductingelliptical cavities. Elliptical cavities play a central role in modern particle ac-celerators due to their high efficiency. After an introduction to the EuropeanSpallation Source project, the thesis goes through the design of the medium-βcavity. The RF design of the inner cell and end cell are presented in sequencein paper I . T
The accelerator of the European Spallation Source (ESS) is a 5 MW proton linac to be built in Lund Sweden. Its superconducting section is composed of 3 cavity families: double spoke resonators, medium beta and high beta elliptical multi-cell cavities. This paper presents the electromagnetic and mechanical design of the elliptical cavities. Both elliptical families are housed in 4-cavity cryomodule
In this paper a linear regression analysis is used to analyze the behavior of the inner cell of an elliptical cavity. The aim is to understand how the RF parameters are correlated to each other and how they are affected by the change of the geometric parameters. This is done by fitting the RF data to a linear model. The data is obtained by simulating a set of different inner cells automatically by
This study explores the application of spatial modelling techniques to generate susceptibility maps for a neglected zoonotic disease, visceral leishmaniasis (VL), in an endemic area in southern Caucasus that includes Iran, Armenia and Azerbaijan. The social and physical environment of southern Caucasus has been mainly characterized by the presence of several factors that are strongly associated wi
In the EU, it is believed that the potential benefits of academic R&D are not fully reaped. Much attention is, therefore, given to enhancing commercialisation in the form of academic spin-offs, patents and licences. There are, however, a number of problems with this way of analysing the effects of academic R&D. Its contribution must instead be captured by a systems approach and we go some
In assessing the performance of academic research, there is a growing interest in combining excellence with impact criteria. A frequently encountered belief is that impact should be understood in terms of new firms and patents. Others argue that academic R&D generates impacts that greatly exceed such commercialization efforts by academic researchers. The tension between these two beliefs revea
It is commonly believed that the academic sector does not generate enough value for society. This value is often measured in terms of new firms, patents and products, leading to policy responses which aim to enhance ‘commercialisation’ by academics. However, others maintain that academic research generates benefits in many ways, some of which are difficult to measure, and that policy must look bey
Some policymakers believe that academic R&D generates insufficient economic benefits. However, they often exclude the long-term and multi-dimensional impacts that are mediated through the activities of companies, students or policymakers. This case study, which is mainly interview-based, traces and characterises such impacts applying the technological innovation systems approach to the case of
The notion that academic research creates societal benefits is widely recognised. However, there are varying perceptions of what such benefits may include, and diverse ideas regarding the ways in which they are created. Some research policy actors expect academic research to generate tangible and direct outputs related to commercialisation, such as spin‐off companies, patents and licences. Others
Marine energy technologies can contribute to meeting sustainability challenges, but they are still immature and dependent on public support. This paper employs the Technological Innovation Systems (TIS) framework to analyze the development and diffusion of Swedish marine energy up until 2014. While there were promising device developers, relevant industrial capabilities, and world-class research,
Water exchange on Pt(H20)42+ and trans-PtCI2(H20)2 has been studied by means of a new oxygen18 tracing technique. The exchange between a platinum(II) complex and 018-enriched water has been rapidly quenched by addition of excess chlorine, which gives a substitution-inert platinum(IV) complex. The time-dependent oxygen16/oxygen18 distributions of the platinum(II) complexes are obtained from the 195
Mobile business intelligence (m-BI), an extension of business intelligence (BI), promises to support decision-making on the move. What is new and interesting about m-BI is the fact that users can access and analyse business information when needed independently of time and place on mobile devices such as smartphones and tablets. This is largely due to the mobile capabilities entailed in m-BI, such
