Decreasing the magnetic field signature of a naval vessel will reduce its susceptibility to detonating naval influence mines and the probability of a submarine being detected by underwater barriers and maritime patrol aircraft. Both passive and active techniques for reducing the magnetic signatures produced by a vessel's ferromagnetism, roll-induced eddy currents, corrosion-related sources, and stray fields are presented.

В книге описываются так называемые концентрические оптические системы, сочетающие большую светосилу со значительным полем зрения. В первой части книги дается общая теория концентрических систем, во второй — применение изложенной теории к конкретным оптическим системам, которые используются или могут использоваться в астрономическом приборостроении. Автор дает простой метод расчета оптических систем и создаваемых ими аберраций с примерами его применения. В частности, рассмотрены такие пользующиеся популярностью системы, как система Максутова, Шмидта, Супер-Шмидт и другие. Рассчитана на оптиков-конструкторов, астрономов-специалистов, аспирантов и студентов астрономической специальности.

Polycrystalline thin-film solar cells have reached a levelized cost of energy that is competitive with all other sources of electricity. The technology has significantly improved in recent years, with laboratory cell efficiencies for cadmium telluride (CdTe), perovskites, and copper indium gallium diselenide (CIGS) each exceeding 22 percent. Both CdTe and CIGS solar panels are now produced at the gigawatt scale. However, there are ongoing challenges, including the continued need to improve performance and stability while reducing cost. Advancing polycrystalline solar cell technology demands an in-depth understanding of efficiency, scaling, and degradation mechanisms, which requires sophisticated characterization methods. These methods will enable researchers and manufacturers to improve future solar modules and systems.
