Deep Underground Neutrino Experiment
The Deep Underground Neutrino Experiment (DUNE) is a neutrino experiment under construction, with a near detector at Fermilab and a far detector at the Sanford Underground Research Facility that will observe neutrinos produced at Fermilab. An intense beam of trillions of neutrinos from the production facility at Fermilab (in Illinois) will be sent over a distance of 1,300 kilometers (810 mi) with the goal of understanding the role of neutrinos in the universe. More than 1,000 collaborators work on the project. The experiment is designed for a 20-year period of data collection. The primary science objectives of DUNE are The science goals are so compelling that the 2014 Particle Physics Project Prioritization Panel (P5) ranked this as "the highest priority project in its timeframe" (recommendation 13).[10] The importance of these goals has led to proposals for competing projects in other countries, particularly the Hyper-Kamiokande experiment in Japan, scheduled to begin data-taking in 2027. The DUNE project, overseen by Fermilab, has suffered delays to its schedule and growth of cost from less than $2B to $3B, leading to articles in the journals Science and Scientific American described the project as "troubled."[11][12] As of 2022, the DUNE experiment has a neutrino-beam start-date in the early-2030's, and the project is now phased.[11][12]

Management System (Open Source)
Management System (Open Source) is a socio-technical system that leverages the cumulative knowledge of management practitioners and evidenced based research from the past 130 years. The system was developed by DoD components in partnership with industry experts and academic researchers and builds off of the US Department of Wars version 1.0 open source management system - Training Within Industry. The system integrates the four organizational components of Product, Structure, Process and People. In addition, the system is based on the 4 capabilities of rapid problem solving underlying the Toyota Production System: Derived from the original research of Steven J. Spear (Harvard Business School, Massachusetts Institute for Technology), the system balances the two dimensions of high performing organizations: integrate the whole (product, structure, process & people); and increase the rate of problem solving to manage the whole (4 capabilities outlined above). Fundamentally, the system sets the standards of management by outlining a doctrine of rules, tactics, techniques, procedures & terms. The standards are intended to motivate change by creating a tension between the organization's "current condition" and the "ideal condition" (i.e. True North). The objective of the system is to deliver more value, in less time, at less cost relative to the competition (better, faster, cheaper). For the DoD, competition is defined by the threats posed by current and potential adversaries.

History of Wind Power
Wind power has been used as long as humans have put sails into the wind. For more than two millennia wind-powered machines have ground grain and pumped water. Wind power was widely available and not confined to the banks of fast-flowing streams, or later, requiring sources of fuel. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for livestock and steam engines. With the development of electric power, wind power found new applications in lighting buildings remote from centrally-generated power. Throughout the 20th century parallel paths developed small wind plants suitable for farms or residences, and larger utility-scale wind generators that could be connected to electricity grids for remote use of power. Today wind-powered generators operate in every size range between tiny plants for battery charging at isolated residences, up to near-gigawatt sized offshore wind farms that provide electricity to national electrical networks. By 2014, over 240,000 commercial-sized wind turbines were operating in the world, producing 4% of the world's electricity.

Art History
Art history is the study of objects of art in their historical development and stylistic contexts; that is genre, design, format, and style. The study includes painting, sculpture, architecture, ceramics, furniture, and other decorative objects. As a term, art history (its product being history of art) encompasses several methods of studying the visual arts; in common usage referring to works of art and architecture. Aspects of the discipline overlap. As the art historian Ernst Gombrich once observed, "the field of art history [is] much like Caesar's Gaul, divided in three parts inhabited by three different, though not necessarily hostile tribes: (i) the connoisseurs, (ii) the critics, and (iii) the academic art historians". As a discipline, art history is distinguished from art criticism, which is concerned with establishing a relative artistic value upon individual works with respect to others of comparable style, or sanctioning an entire style or movement; and art theory or "philosophy of art", which is concerned with the fundamental nature of art. One branch of this area of study is aesthetics, which includes investigating the enigma of the sublime and determining the essence of beauty. Technically, art history is not these things, because the art historian uses historical method to answer the questions: How did the artist come to create the work?, Who were the patrons?, Who were his or her teachers?, Who was the audience?, Who were his or her disciples?, What historical forces shaped the artist's oeuvre, and how did he or she and the creation, in turn, affect the course of artistic, political, and social events? It is, however, questionable whether many questions of this kind can be answered satisfactorily without also considering basic questions about the nature of art. The current disciplinary gap between art history and the philosophy of art (aesthetics) often hinders this inquiry. Art history is not only a biographical endeavor. Art historians often root their studies in the scrutiny of individual objects. They thus attempt to answer in historically specific ways, questions such as: What are key features of this style?, What meaning did this object convey?, How does it function visually?, Did the artist meet their goals well?, What symbols are involved?, and Does it function discursively? The historical backbone of the discipline is a celebratory chronology of beautiful creations commissioned by public or religious bodies or wealthy individuals in western Europe. Such a "canon" remains prominent, as indicated by the selection of objects present in art history textbooks. Nonetheless, since the 20th century there has been an effort to re-define the discipline to be more inclusive of non-Western art, art made by women, and vernacular creativity.

Flexible Circuit Board
Flexible circuit board, also known as flex circuit board, is a special type of printed circuit board where the board has at least a portion which is bendable. Typical use case of flex circuits is referred to as FFC (flexible flat cable) and is used as replacement of cable wires and connectors, in which case the flex circuit is designed without electronic components. Other common use includes components assembled on the flex circuit such as led strip and LCD panel interface. The electronic circuit is designed on flexible plastic substrate, usually polyimide film for its high heat resistance which makes is suitable for solder mounting components. In some cases polyester film may used as substrate material, where heat resistance is not needed and no components are soldered on the board. Instead, the board is printed with an industrial printer capable of dispensing conductive ink such as silver ink or carbon ink onto the polyester substrate. Examples of use are touch sensors in computer keyboards for key press detection.

Recovery Approach
Psychological recovery or recovery model or the recovery approach to mental disorder or substance dependence emphasizes and supports a person's potential for recovery. Recovery is generally seen in this approach as a personal journey rather than a set outcome, and one that may involve developing hope, a secure base and sense of self, supportive relationships, empowerment, social inclusion, coping skills, and meaning. Recovery sees symptoms as a continuum of the norm rather than an aberration and rejects sane-insane dichotomy. William Anthony, Director of the Boston Center for Psychiatric Rehabilitation developed a quaint cornerstone definition of mental health recovery in 1993. "Recovery is a deeply personal, unique process of changing one's attitudes, values, feelings, goals, skills and/or roles. It is a way of living a satisfying, hopeful, and contributing life even with limitations caused by the illness. Recovery involves the development of new meaning and purpose in one's life as one grows beyond the catastrophic effects of mental illness." The use of the concept in mental health emerged as deinstitutionalization resulted in more individuals living in the community. It gained impetus as a social movement due to a perceived failure by services or wider society to adequately support social inclusion, and to studies demonstrating that many people do recover. A recovery approach has now been explicitly adopted as the guiding principle of the mental health or substance dependency policies of a number of countries and states. In many cases practical steps are being taken to base services on a recovery model, although a range of obstacles, concerns and criticisms have been raised both by service providers and by recipients of services. A number of standardized measures have been developed to assess aspects of recovery, although there is some variation between professionalized models and those originating in the psychiatric survivors movement.
