Abstract
The current trend towards the Industrial Internet of Things raises new requirements regarding the connectivity of distributed automation systems. Time-sensitive Networking is a new IEEE standard fulfilling these requirements by providing determinism and real-time for convergent networks. The networks in this domain are currently configured manually, but the rising number of network nodes, more frequent reconfigurations and the combination of different scheduling mechanisms will make a manual network configuration infeasible. My proposed Ph.D. thesis strives to automate the network configuration for real-time, distributed industrial automation systems. This can be accomplished by deducing the relevant network requirements from extended domain-specific models (e.g., IEC 61499) and synthesizing network schedules according to the deduced information that can be transformed into constraints and solved by constraint-based solvers like Satisfiability Modulo Theorem solvers.

Abstract
One hundred and seventy two men at the State of Thessaly, Greece, inquiring semen analysis were enrolled in the study in order to investigate the incidence of Chlamydia, Ureaplasma and Mycoplasma (C-U-M) genera in respect to total sperm number (TSN), progressive motility (grades a and b) and total motility (grades a, b and c). Putative relation of C-U-M acquirement with sexual behavior was also investigated. Incidence of C-U-M among non-oligozoospermic and oligozoospermic men was similar. correlation of C-U-M carriage to either oligozoospermia or asthenozoospermia was found. The tested semen parameters were negatively correlated to the age of sexual intercourse initiation and positively correlated to the number of sex partners. Early age of sexual intercourse initiation or high number of sexual partners was not statistical significantly correlated to C-U-M acquirement. Overall, TSN and motility (either progressive or total) were not influenced by the presence of C-U-M genera in a sample of Greek population undergoing semen evaluation. To distinguish the role of C-U-M in male infertility and clarify the so far controversial scarce literature, large control case studies are needed using nucleic acid amplification techniques to detect these pathogens.
