Flight Operations

This chapter is a brief overview of some important milestones in the history of aviation. Armed with this knowledge it is hoped that the reader can gain some appreciation of the necessity, and indeed the urgency, of providing additional decision and targeted activity support for flight crews of modern high-speed commercial and military aircraft. It is important to realize that as aviation advanced from simple single-engine aircraft capable of flying not more that about 100 MPH, to advanced, multi-engine aircraft with international capabilities, complexity, and mental workload increased exponentially. This in turn has increased our attention to understanding how to support the flight crew better. This chapter is a brief historical overview, a mission structural representation, and some discussions on flying in adverse conditions.

Never before in the history of aviation has the test pilot been so important as he is today. Now that military aircraft are travelling faster than the speed of sound and climbing to over 50,000 ft. in a matter of seconds, with powered controls, pressurised cabins, ejector seats, special oxygen equipment and such like being the order of the day, it is little wonder that the human being whose job it is to fly in these modern high-speed missiles requires more than ordinary Service flying experience if he is to take his place successfully in the team with today's technicians and designers. The day has long since passed when any good pilot could set himself up as a test pilot. The term “test pilot” covers a large field of work, testing aircraft and the complicated equipment fitted in the new revolutionary designs being produced.

Thin GexTe1-x (x = 0.15-0.8) were studied as a model substance of a composite semiconductor film, in addition being of interest for optical storage material. Two complementary modes of time-resolved TEM were used to trace the phase transitions, induced by an attached Q-switched (50 ns FWHM) and frequency doubled (532 nm) Nd:YAG laser. The laser radiation was focused onto the specimen within the TEM to a 20 μm spot (FWHM). Discrete intermediate states were visualized by short-exposure time doubleframe imaging /1,2/. The full history of a transformation was gained by tracking the electron image intensity with photomultiplier and storage oscilloscopes (space/time resolution 100 nm/3 ns) /3/. In order to avoid radiation damage by the probing electron beam to detector and specimen, the beam is pulsed in this continuous mode of time-resolved TEM,too.Short events ( <2 μs) are followed by illuminating with an extended single electron pulse (fig. 1c)

The article is devoted to the history of reception and interpretation of the ideas of Marx and Engels. The author considers the reasons for divergence between Marxist and neoclassical economic theories. He also analyzes the ways of vulgarization of Marx’s theory and the making of Marxist voluntarism. It is shown that the works of Marx and Engels had a certain potential for their over-simplified interpretations. The article also considers academic ("Western") Marxism and evaluates the prospects of Marxist theory in the future.

The article reviews O. A. Shashkova’s ‘... Call the Mute Artifacts to Speech.’ Essays on the History of Archaeography of the 15th - Early 20th Century. Wide array of sources and broad geographical frameworks allow Shashkova to present emergence and development of Russian and European archaeography from the 15th to early 20th century intelligibly enough for educational purposes. A whole chapter is devoted to the manuscript tradition and publishing of sources before Gutenberg. When considering the formation of archaeographical tradition, the author uses comparative method. O. A. Shashkova offers a historical overview and analyzes theoretical and practical issues of archaeography. The reviewer notes the significance of the chosen topic due to a need to reconsider the development of publishing in light of modern views on archaeography and to make it accessible to students and non-professionals. She notes traditional academic approach of O. A. Shashkova to presentation of the development publication practices. The review considers the possibility of using the ‘Essays...’ in studying the history of archaeography and offers possible directions for a broader consideration of historical experience, in particular, of Novikov’s publication projects. The review notes the controversial nature of the author’s approach to systematization of her large historical material in order to consider issues concerning the study of archaeographical practices. It stresses that coverage of issues of development of methods of preparation of publications separately from its historical and practical aspects hinders successful mastering of the material by an untrained reader. It concludes that the publication has high practical value for specialists in archaeography and students.


This book is the first to examine the history of imaginative thinking about intelligent machines. As real artificial intelligence (AI) begins to touch on all aspects of our lives, this long narrative history shapes how the technology is developed, deployed, and regulated. It is therefore a crucial social and ethical issue. Part I of this book provides a historical overview from ancient Greece to the start of modernity. These chapters explore the revealing prehistory of key concerns of contemporary AI discourse, from the nature of mind and creativity to issues of power and rights, from the tension between fascination and ambivalence to investigations into artificial voices and technophobia. Part II focuses on the twentieth and twenty-first centuries in which a greater density of narratives emerged alongside rapid developments in AI technology. These chapters reveal not only how AI narratives have consistently been entangled with the emergence of real robotics and AI, but also how they offer a rich source of insight into how we might live with these revolutionary machines. Through their close textual engagements, these chapters explore the relationship between imaginative narratives and contemporary debates about AI’s social, ethical, and philosophical consequences, including questions of dehumanization, automation, anthropomorphization, cybernetics, cyberpunk, immortality, slavery, and governance. The contributions, from leading humanities and social science scholars, show that narratives about AI offer a crucial epistemic site for exploring contemporary debates about these powerful new technologies.

Qualitative research does not represent a monolithic, agreed-on approach to research but is a vibrant and contested field with many contradictions and different perspectives. To respect the multivoicedness of qualitative research, this chapter will approach its history in the plural—as a variety of histories. The chapter will work polyvocally and focus on six histories of qualitative research, which are sometimes overlapping, sometimes in conflict, and sometimes even incommensurable. They can be considered articulations of different discourses about the history of the field, which compete for researchers’ attention. The six histories are: (a) the conceptual history of qualitative research, (b) the internal history of qualitative research, (c) the marginalizing history of qualitative research, (d) the repressed history of qualitative research, (e) the social history of qualitative research, and (f) the technological history of qualitative research.

This chapter details how slavery, segregation, and racism impacted the educational experiences of African Americans from the colonial era to the present. It offers a historical overview of the African American educational experience and uses archival data and secondary source analysis to illustrate that America has yet to be a truly post-slavery and post-segregation society, let alone a post-racial society.

The article, dedicated to the 35th anniversary of the start of production at the Volgograd Tractor Plant of the tracked agricultural tractor DT-175S "Volgar", tells about the history of the creation of this unique machine in its own way. (Research purpose) The research purpose is in analyzing the history of the creation and production, the effectiveness of the use of the DT- 175S "Volgar" tractor, considering the stages and directions of its improvement. (Materials and methods) The article de-scribes the history of the creation of the high-speed energy-saturated tractor "Volgar", gave its design features, technical characteristics in comparison with its predecessors, the results of tests in various soil and climatic zones, on various agricultural operations. (Results and discussion) In the DT-175S "Volgar" tractor, the designers, in close cooperation with scientists, embodied the results of research aimed at increasing the working speeds of machine-tractor units, and the most advanced technical solu-tions in the field of tractor construction at that time. The main of these solutions is an automatic continuously variable hydro-mechanical transmission. The combination of a powerful (125 kilowatt) engine with a similar transmission allowed not only signifi-cantly increase the working speed and productivity of the tractor, up to 9-15 kilometers per hour, but also significantly reduce the labor intensity of the tractor driver. The article presents the information about the improvement, modernization of the tractor, the creation of various specialized modifications on its basis. DT-175S "Volgar" be-came the most powerful serial machine of the Volgograd Tractor Plant, rightfully earned the respect of specialists of farms and machine operators. (Conclusions). Further development of the application of the automatic hydro-mechanical transmission on agricultural tractors was to receive the VT-200D tractor of 5th traction class with a capacity of 147 kilowatts. Due to the complication of the economic situation, the production of this tractor was lim-ited to only a small experimental batch.

The Trusteeship Council held its tenth special session at UN Headquarters on December 4 and 16, 1959. Following the adoption of its agenda, the Council entered into consideration of the report of the UN Plebiscite Commissioner on the plebiscite in the northern part of the trust territory of the Cameroons under United Kingdom administration. In introducing the first part of the report, Mr. Abdoh, UN Plebiscite Commissioner, reviewed the history of his consultations with the United Kingdom government on arrangements for the organization of the plebiscite. He observed that, as a result of being administered for many years as an integral part of the northern region of Nigeria, the Northern Cameroons had previously had very little reality as a separate administrative entity; in fact, boundaries with the northern region of Nigeria had little significance, and tribal groups extended from that region into the trust territory and even beyond, to the Cameroons under French administration. Communications in the Northern Cameroons were poor, but, despite adverse conditions, the UN plebiscite staff had travelled extensively and had been able to meet both the people and their leaders. Mr. Abdoh added that he wished to stress the peaceful and orderly way in which polling had been conducted throughout the territory, and mentioned the results of the plebiscite, viz.: out of the 113,859 votes cast, 70,546 had been in favor of deciding the future of the Cameroons at a later date (alternative b), while 42,788 had indicated a preference for the Northern Cameroons' becoming a part of the northern region of Nigeria when Nigeria became independent (alternative a); 525 votes had been rejected. Approximately 80 percent of the estimated number of potential electors, and nearly 88 percent of the voters actually registered, had participated in the balloting; thus the greater part of the eligible population had taken part in the consultation, freely expressing their wishes in regard to the alternatives offered in the plebiscite. Mr. Abdoh had, however, felt it his duty to inform the Council of the view, which seemed to be prevalent among those who had voted for the second alternative, that the plebiscite had offered the people an opportunity of registering what was in effect a protest against the system of local adminstration, the introduction of reforms into which was apparently long overdue.
