Nuclear structure calculations for neutron-star crusts

The goal of this paper is to investigate properties of clusterized nuclear matter which is believed to be present in crusts of neutron stars at subnuclear densities. It is assumed that the whole system can be represented by the set of Wigner-Seitz cells, each containing a nucleus and an electron background under the condition of electroneutrality. The nuclear structure calculations are performed within the relativistic mean-field model with the NL3 parametrization. The first set of calculations is performed assuming the constant electron background. The evolution of neutron and proton density distributions was systematically studied along isotopic chains until very neutron-rich system beyond the neutron dripline. Then we have replaced the uniform electron background with the realistic electron distributions, obtained within the Thomas-Fermi approximation in a self-consistent way with the proton distributions. Finally, we have investigated the evolution of the $\beta$-stability valley as well as neutron and proton driplines with the electron density.Comment: 21 pages, 14 figure

Analysis, Modeling and Testing of a Multi-Receiver Wireless System for Telemetry Applications

This thesis investigates the potential value of multiple co-located receiver units for telemetry applications. In this thesis, a test board based on the NRF24L01 RF chip produced by Nordic Semiconductor was tested. Testing consisted of sending pseudo-random test data over a link between two test boards at progressive distances. Packet loss rate was identified as the dominant failure mode of the chip, and was used to determine performance increase. A parametric model of the chip performance was developed based on coherent and noncoherent FSK detectors and curve fit to the experimental data to model the performance of a single GFSK receiver with unknown parameters. The chip exhibited an estimated 10 fold improvement in bit error performance at short range, with the performance improvement dropping off as distance increased. This result implies that there may be significant utility to using multiple receiver systems when traditional methods of improving performance such as amplifiers and antennas do not provide the necessary benefit

A Review on the Customer Role in Smart Service Co-Creation

In the course of digital servitization and the introduction of smart services, the provider-customer relationship in manufacturing industries is changing. The cooperation between providers and customers, which is also referred to as co-creation in research, can have a positive impact on the value creation of both parties in the various development phases of smart service. Co-creation is understood as a two-way communication in which providers and customers can exchange their resources, for example in the form of knowledge and skills. However, so far research has focused on the role of the provider in this constellation. Through a systematic literature review, this article examines the role of customers within industrial smart services. Four core areas could be identified within co-creation. These are discussed in the context of existing paradoxes and it is shown that the customer perspective should be given equal consideration in future research
