Launching Site

It is shown that the most prominent shortcomings of the existing general sectoral scientific and technical policy for the development of means of information and telemetry support (ITS) of development of launch vehicles are manifested in the absence of a systemic and dominance of subjective and fragmentary approaches, as a result of which the software and hardware (SW&HW) of the telemetric complex (TC) of a space launching site are redundant, but not invariant to the current ITS problems. At the same time, the loss of information during launches of spacecraft (SC) and intercontinental ballistic missiles (ICBMs) due to the influence of harmful factors of a different nature are comparable to the losses experienced during the 60s–70s of the 20th century. Under these conditions, a systematic approach is relevant and, accordingly, the regulation of the development process of domestic systems for information and telemetric support for the development of launch vehicles (ITSDLV). The main regulatory tools are the official concept of development of ITSDLV and the corresponding system of telemetry standards. The scientific and methodological foundations of their construction, based on the results of past research, are presented. The features of the solution of current and future organizational issues for the maintenance and development of the aforementioned concept and system of standards by the forces of the proposed working group are shown.

Did the nuclear revolution contribute to an era of peace? ‘Nuclear deterrence and arms control’ looks at the post-World War II stalemate and Cold War détente. The concept of deterrence did not come up until the second decade of the nuclear age. The introduction of thermonuclear weapons and nuclear-tipped, long-range intercontinental ballistic missiles turned foreign policy on its head. Mutual deterrence was less of a policy than a reality. With the Cuban Missile Crisis, Moscow mounted a show of defiance at a moment when it was relatively weak. The Carter and Reagan administrations were beset by external and internal disagreements, but prudence and luck prevailed.

Null Pointer

Abstract Context Issue tracking systems are used to track and describe tasks in the development process, e.g., requested feature improvements or reported bugs. However, past research has shown that the reported issue types often do not match the description of the issue. Objective We want to understand the overall maturity of the state of the art of issue type prediction with the goal to predict if issues are bugs and evaluate if we can improve existing models by incorporating manually specified knowledge about issues. Method We train different models for the title and description of the issue to account for the difference in structure between these fields, e.g., the length. Moreover, we manually detect issues whose description contains a null pointer exception, as these are strong indicators that issues are bugs. Results Our approach performs best overall, but not significantly different from an approach from the literature based on the fastText classifier from Facebook AI Research. The small improvements in prediction performance are due to structural information about the issues we used. We found that using information about the content of issues in form of null pointer exceptions is not useful. We demonstrate the usefulness of issue type prediction through the example of labelling bugfixing commits. Conclusions Issue type prediction can be a useful tool if the use case allows either for a certain amount of missed bug reports or the prediction of too many issues as bug is acceptable.

Subject Hypersonic missiles and their implications. Significance Russia and China claim to have hypersonic weapons with near-global reach, capable of delivering nuclear warheads with certainty and overcoming US anti-ballistic missile (ABM) defences designed to intercept intercontinental ballistic missiles (ICBMs). The implication is that both countries are ahead of the United States in the technology race. Impacts Hypersonic technology poses a new challenge just as the future of the New START arms treaty is due for renewal in 2021. While the Kremlin highlights future hypersonic weapons, broader procurement of new defence systems is lagging. US and Chinese designers are investigating potentially cheaper methods of accelerating artillery shells to hypersonic velocities.

Intercontinental Ballistic Missiles

Edwin Ginn's vision of world peace, as recorded in his last will and testament, involved him in a commitment to world government. World government, however, is an objective which seems to many mid-twentieth century observers of international politics excessively visionary. The nineteenth-century dream of a parliament of man, a federation of the world, fills a bright page in Victorian poetry. But much contemporary prose is written by men whose vision is obscured by space rockets, intercontinental ballistic missiles, atomic bombs, and other lethal weapons of ultramodern warfare. They see only a world of heavily armed, self-styled sovereign states bent on the protection of alleged vital interests and on the defense of so-called national honor with little patience for the restraints of any higher law designed to prevent them from making war upon one another.

The design and control problems involved in the development process of robotic grippers have been active research topics in the last three decades. In this paper it is presented a new developed dexterous robotic hand whose mechanical structure is based on a biomechatronic approach. The control system for this artificial hand relies on modern software and hardware components which allow precise positioning of the fingers.

Key Factor

Domain-Specific Languages (DSLs) can be regarded as User Interfaces (UIs) because they bridge the gap between the domain experts and the computation platforms. Usability of DSLs by domain experts is a key factor for their successful adoption. The few reports supporting improvement claims are persuasive, but mostly anecdotal. Systematic literature reviews show that evidences on the effects of the introduction of DSLs are actually very scarce. In particular, the evaluation of usability is often skipped, relaxed, or at least omitted from papers reporting the development of DSLs. The few exceptions mostly take place at the end of the development process, when fixing problems is already too expensive. A systematic approach, based on techniques for the experimental evaluation of UIs, should be used to assess suitability of new DSLs. This chapter presents a general experimental evaluation model, tailored for DSLs’ experimental evaluation, and instantiates it in several DSL’s evaluation examples.

Space Security

The use and exploration of space by humans is historically implicated with international and national security. Space exploration itself was sparked, in part, by the race to develop intercontinental ballistic missiles (ICBM), and the strategic uses of space enable the global projection of force by major military powers. The recognition of space as a strategic domain spurred states to develop the initial laws and policies that govern space activities to reduce the likelihood of conflict. Space security, therefore, is a foundational concept to space law. Since the beginning of the Space Age, the concept of security has morphed into a multivariate term, and contemporary space security concerns more than just securing states from the dangers of ICBMs. The prevalence of space technologies across society means that security issues connected to the space domain touch on a range of legal regimes. Specifically, space security law involves components of international peace and security, national security, human security, and the security of the space environment itself.
