The paper describes a fast forward electromagnetic model built with help of commercial software. The purpose of this paper is to create an efficient and robust electromagnetic field model that could be easily plugged into a working microwave imaging system. The secondary purpose is to evaluate advantages and disadvantages of such a commercial packages for creating such a model.

In this paper the authors decided to build the model using COMSOL Multiphysics software suite, ultimately comparing its result to measurements of a real device. The numerical model was created in an iterative fashion in order to determine how much details are needed to make it reliable, while keeping it efficient.

The authors found that the commercial software seems like a viable platform for developing electromagnetic solvers. The resulting computer model is easy to prepare, run and integrate with external tools.

Using the experience in building numerical models of various systems the authors came to the conclusion that developing some in-house code is a very non-efficient technique as it slows down the progress of the research team once the team changes. Transfer of knowledge associated with the numerical tools is much easier when the tools are constructed using a common platform, i.e. commercial packages. It does not really matter if the software is free or proprietary as long as the platform provides efficient tools assisting in model preparation and data visualization.

One of the main advantages of using such a full field electromagnetic model is the ability to investigate an impact of different properties of the system (length of antennas, liquid parameters) on its performance. Thanks to the use of commercial software it is much easier to pass the project to new people too.

The presented numerical model utilizes a frugal meshing scheme which allows faster execution while keeping required accuracy of solutions. Using this model the authors were able to diagnose important geometrical details that could affect the performance of the system.

The Nationalökonomische Gesellschaft (Austrian Economic Association, NOeG) provides a prominent example of the Viennese economic circles and associations that more than academic economics dominated scientific discourse in the interwar years. For the first time this chapter gives a thorough account of its history, from its foundation in 1918 until the demise of its long-time president, Hans Mayer, 1955, based on official documents and archival material. The topics treated include its predecessor and rival, the Gesellschaft österreichischer Volkswirte, its foundation in 1918 soon to be followed by years of inactivity, the relaunch by Mayer and Mises, the survival under the NS-regime and the expulsion of its Jewish members and the slow restoration after 1945. In particular, an attempt is made to provide a list of the papers presented to the NOeG, as complete as possible, for the period 1918–1938.

This paper aims to discuss the emergence of science, technology and innovation (STI) institutions in Indonesia during the Dutch East Indies colonial period in 1778–1941. The emergence of these institutions reflected the dynamics of science and technology development and innovation in that era.

This paper navigates a historiographical approach. Data collection techniques use “secondary data research,” with archival investigation published by official sources in the Dutch East Indies in the 18th and 19th centuries as well as other reference sources, and data analysis techniques use “supplementary analysis.”

This research indicates that the STI institution during the Dutch East Indies colonial period was formed to maximize the natural resources of the Dutch East Indies. The STI institution at that time was constructed as part of Buitenzorg’s Plantentuin the lands, plantations, solutions for health, astronomy, geology, forestry and culture.

The limitations of this research, as well as future research. Relying too much on “secondary data” is a limitation of this study. Therefore, it is necessary to collect primary data through in-depth interviews with historical scientists studying STIs in Indonesia in future research.

This study, to the best of the authors’ knowledge, considered the first study, reveals the dynamics of STI in Indonesia during the Dutch East Indies colonial era by examining the dynamics of the institution. In addition, this study succeeded in dividing five institutional STI clusters in the Dutch East Indies Colonial period 1778–1941, namely, units/institutions formed as part of Planuntungin te Buitenzorg; units/institutions formed based on plantations, initiated by private plantations to find solutions to the pests and diseases that attack their crops; units/institutions formed to seek solutions in the health sector; units/institutions formed based on astronomy, geology and forestry; and units/ institutions regarded as scientific councils/associations.
