In 2001, a paper published in Nature by Andrews et al postulated the use of six co-located antennas, namely three electric and three magnetic dipoles, to achieve up to a six-fold capacity increase in wireless channels, relative to that of a single antenna. In other words, six degrees of freedom (DOFs) can be supported in a wireless channel with co-located six-port transmit and receive antenna arra

Idag är datorer viktiga verktyg för blinda personer men används mest som text maskiner. Den omfattande användningen av Internet som informationskanal har lett till en smärre revolution för synskadade personer genom att ge dem tillgång till information som

Using the optical double resonance and level crossing methods, properties of several excited S , P , and D states in 39 K were studied. The S and D states were populated using stepwise excitation with the first P state as an intermediate level. An rf lamp and a CW dye laser were used in the first and second excitation steps, respectively. The studied P states were populated in the cascade decay of

Oxide nanoparticle layers have shown interesting behavior as gate materials for high temperature (typically at 300-400°C) metal-insulator-silicon carbide (MISiC) capacitive sensors. Distinct shifts in the depletion region of the C-V (capacitance-voltage) characteristics could be observed while switching between different oxidizing and reducing gas ambients (air, O2, H2, NH3, CO, NOx, C3H6). Shifts

Nonlinear propagation of electromagnetic waves is an important problem in optics. Often the properties of the nonlinear media are not fully understood. The solution of an inverse problem can provide an aid to that understanding. An inverse transmission problem is posed, it is one of reconstructing the medium parameters, by measurement of a wave that has been propagated through the nonlinear medium

This paper considers a two-echelon distribution inventory system with a central warehouse and a number of retailers. There is direct customer demand also at the warehouse. If this upstream demand requires a high service, it may be advantageous to give higher priority to customer orders compared to retailer replenishments. We suggest and evaluate techniques for handling this situation. One techniqu

This paper studies regional museum, archives and arts education commissions of the Region of Scania, reformed in 2009, from a policy analysis perspective. It describes the background, design and implementation of the new policy and analyses its effects. The paper gives detailed information on the complexities of policy tool design and implementation, and discusses it in the light of regional gover

SAAB Dynamics produces and develops warheads and uses computer simulations to evaluate its products. Recently, SAAB has begun using neural networks to quickly obtain accurate outputs, based on simulated data, from a set of input variables with success. This thesis investigated whether interim data in the form of video frames can improve the output of the network. This thesis investigated the use o

Power consumption has become a leading concern for SoC aimed at 5G products that demand increased functionality, smaller form factors, and low energy footprint. For some EMCA IP blocks a hierarchical clock gating mechanism ensures coarse-grained power savings based on actual processing need but for many blocks this approach cannot be employed. This implies that these blocks have to rely on a high

Studies on several target factors like specific antigens, biomarkers and cellular signals involved in High-risk Human papilloma virus (HR-HPV) infection and its mediated immune response aid in narrowing the gap to generate effective therapeutic solutions for oropharyngeal carcinomas. Thus, establishing cytotoxic T-lymphocytes (CTL) lines will aid in investigating and carrying out functional studie

Batch high-shear mixers are used in a variety of different processing industries,such as the pharmaceutical, chemical and food industries. One company that utilize this type of mixers is Tetra Pak. High-shear mixers can be used for many different mixing scenarios, but only liquid-liquid mixing is discussed in the thesis. The batch high-shear mixer is constructed with a rotor-stator at the bottom o
