The thesis of this article is that cyber war technologies are spilling over into precision strike and nuclear mission areas. The result will transform deterrence and arms race stability and lead to other significant changes. The driver behind this is a combination of long standing problems with mobile missiles along with new technologies not usually factored into strategic assessments: big data...

An account has been given of two experiments in which three monkeys were carried in Jupiter missiles 300 miles inro space. In the first, a squirrel monkey survived in .good .condition till a mishap .occurred to the vehicle on re-entry. In the second, an American-born rhesus and a squirrel monkey were recovered uninjured. Details have been furnished covering the construction of the biocapsules, ...

The length and volume requirements of small gas turbines for missiles or propelled targets lead to combustor designs with high combustion intensity and large value of the air loading parameterA. The conventional combustors have used conditions corresponding toll values in the 1 to 10 kg m -3s 1 range. The increase off?required for combustors in missiles conduces for existing liners to a decreas...

The application of fuzzy logic for the development of guidance laws for homing missiles is presented. Fuzzy logic approximation of the well known proportional navigation guidance law is discussed, followed by the development of a blended guidance law using fuzzy logic. The objective of the latter guidance law is to combine desirable features of three homing guidance laws to enhance the intercep...

As so-called “wooden rounds”, which are intended to sit stably in storage for extended periods and then function precisely as desired, at a moment’s notice, Air Force missiles would appear to be an ideal application for health monitoring. However, solid rocket motors that serve as the propulsion system for these missiles present a number of unique challenges for the development of integrated ve...

Crossword puzzles are popular word games that require not only a large vocabulary, but also a broad knowledge of topics. Answering each clue is a natural language task on its own as many clues contain nuances, puns, or counter-intuitive word definitions. Additionally, it can be extremely difficult to ascertain definitive answers without the constraints of the crossword grid itself. This task is...

The problem of two cracks emanating from the same origin and propagating asymmetrically at different velocities in an elastic and isotropic solid is treated in this paper. An unbounded and otherwise undisturbed medium and a constant anti-plane loading at infinity were assumed. Techniques of self-similar elastodynamics were utilized in conjunction with analytic-function theory. Since a closed-fo...

A benzobisoxazole-based cruciform fluorophore forms fluorescent complexes with simple boronic acids. Through the changes of their fluorescence emission colours, these complexes can sense and qualitatively distinguish among structurally similar organic nitrogen compounds (amines and ureas) and small organic and inorganic anions. Preliminary results suggest that the intensity of this hybrid senso...
