I T is perhaps not too surprising (at least for a control audience) that “manipulating and controlling things at a small scale” was already a key part of the program that Richard P. Feynman formulated in his 1959 visionary lecture [1] which is commonly recognized as the birth place of Quantum Information. Quoting from [1]: “The principles of Physics as far as I can see do not speak against the ...

The paper at hand argues that ontological components should be incorporated into command and control systems in order to increase their level of interoperability. The term “ontology” is explained, and capabilities of ontological components are illustrated by example. The example’s lessons are generalized and exploited for an advanced approach. 1.0 INTRODUCTION Ongoing and future operations are ...

In his October 2020 column titled “Career choices” (page 8), Charles Day introduces three individuals whose obituaries appeared in different issues of Physics Today 1998. One the themes was why selected careers that they did, all which grew out their having doctoral degrees physics.One people mentioned Rutherford Adkins, who after being drafted 1941 became a member Tuskegee Airmen, first Africa...

Existing methods to text plagiarism analysis mainly base on “chunking”, a process of grouping a text into meaningful units each of which gets encoded by an integer number. Together theses numbers form a document’s signature or fingerprint. An overlap of two documents’ fingerprints indicate a possibly plagiarized text passage. Most approaches use MD5 hashes to construct fingerprints, which is bo...

We present semantic markup as a way to exploit the semantics of mathematics in a wiki. Semantic markup makes mathematical knowledge machine-processable and thus allows for a multitude of useful applications. But as it is hard to read and write for humans, an editor needs to understand its inherent semantics and allow for a humanreadable presentation. The semantic wiki SWiM offers this support f...

During recent years more and more cases of lymphopathia venereum (lymphogranuloma inguinale) are being diagnosed as the clinical features and tests are better understood. If left untreated, or even in treated cases, the disease can result in much suffering and disfiguring due to scarring. Of the local method of treatment chief reliance has been placed on the time-honoured belladonna and ichthyo...
