Towalink – an Open and Flexible Site Networking Solution

D. Henrici and L. Wischhof
Topic:
Software Tools and Applications
Abstract
Securely and reliably connecting multiple operating sites using existing Internet access lines is a common requirement for companies as well as individuals. Towalink is a new open and flexible solution for interconnecting multiple network sites reliably and securely. It is built around proven open-source projects and by itself published open-source. We present in theory and based on a practical setup the central management it provides and show how it is following the infrastructure-as-code paradigm.
Keywords

Combining Speech Processing and Text Processing in Conceptual Database Design

D. Brdjanin, G. Banjac, D. Keserovic, N. Babic, and N. Golubovic
Topic:
Speech Processing
Abstract
The paper presents an approach to automated conceptual database design that combines speech processing and text processing techniques for the automated derivation of conceptual database models from recorded speech. In the first phase, the recorded speech is converted to the corresponding text by applying speech processing techniques. In the second phase, the text is converted to the corresponding conceptual database model by applying text processing techniques. The proposed approach is supported by an online tool named SpeeD, which is the first tool enabling automated derivation of conceptual database models from recorded speech, whereby several different natural languages are supported.

Miniaturization of Directional Couplers without the use of Multilayer Substrates by Changing the Design of the Capacitor

D. A. Letavin
Topic:
Applied Electromagnetics
Abstract
When the limit miniaturization of the coupler is achieved when the elements are located in one conductive layer, then miniaturization can be continued by changing the design of the capacitor that is part of the filter: reducing the gap between the plates or increasing the dielectric constant between the capacitor plates, and due to the movable plates, you can change the operating frequency of the coupler.
Keywords
plates, permittivity, cutouts in the substrate, miniaturization.
