Ekosistem adalah suatu produk interaksi antara berbagai organisme dan antara organisme dan lingkungannya. Ekosistem merupakan benda nyata dalam berbagai skala dan berbagai ciri dapat digunakan untuk mengenalinya. Ciri-ciri vegetasi atau komunitas tumbuhan adalah yang paling mudah digunakan, karena wujud vegetasi merupakan cerminan penampakan luar dari interaksi antara tumbuhan, hewan, dan lingkungannya. Dengan demikian tipe vegetasi dapat disamakan dengan tipe ekosistem. Indonesia adalah negara kepulauan di kawasan tropik yang mencakup kisaran iklim geografi dan geologi yang luas dengan keanekaragaman flora, vegetasi, dan ekosistem yang sangat tinggi. Buku ini menyajikan pertelaan singkat tipe-tipe ekosistem alam Indonesia, yang diekspresikan dengan tipe-tipe vegetasi alam, yang belum terganggu kegiatan manusia dan dilengkapi dengan foto-foto berwarna. Penulis telah mencoba menghimpun dan menyarikan data yang ada tentang vegetasi alam dan segi-segi ekologi lain yang terkait di Indonesia, termasuk hasil pengamatan lapangan penulis, dan diintegrasikan ke dalam buku ini. Penyajian buku ini mencakup klasifikasi vegetasi dan pertelaan singkat tentang komposisi spesies dan struktur masing-masing tipe. Uraian ini akan bermanfaat bagi mahasiswa umum yang ingin mengenal berbagai tipe ekosistem Indonesia. Diharapkan bahwa informasi yang disajikan akan juga memberi manfaat bagi penelitian selanjutnya, pendidikan konservasi dan lingkungan, pecinta alam, dan wisatawan yang berwawasan perikehidupan. Uraian ini akan mempunyai nilai guna pula bagi para pengambil keputusan untuk pengelolaan dan pemanfaatan sumber daya hayati dalam pembangunan serta ekosistem alam Indonesia.

Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.

A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU ́s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising or not) and that of the soft segments. Crystallinity has been sometimes observed in the commercial PUs hard phase but this is usually limited to only a few percent for most hard segment structures when solidified from the melt. One particular diisocyanate, 4,4’-dibenzyl diisocyanate (DBDI) that, in the presence of suitable chain extenders ( diols or diamines), gives rise to significant degrees of crystallinity [i-iii] and this is included in the present work. Understanding the reaction pathways involved, in resolving the subtle morphological evolution at the nanometre level, and capturing mathematically the complex, large-deformation nonlinear viscoelastic mechanical behaviour are assumed to bring new important insights in the world basic research in polyurethanes and towards applied industrial research in this area.

Principles of Flight Simulation is a comprehensive guide to flight simulator design, covering the modelling, algorithms and software which underpin flight simulation. The book covers the mathematical modelling and software which underpin flight simulation. The detailed equations of motion used to model aircraft dynamics are developed and then applied to the simulation of flight control systems and navigation systems. Real-time computer graphics algorithms are developed to implement aircraft displays and visual systems, covering OpenGL and OpenSceneGraph. The book also covers techniques used in motion platform development, the design of instructor stations and validation and qualification of simulator systems. An exceptional feature of Principles of Flight Simulation is access to a complete suite of software (www.wiley.com/go/allerton) to enable experienced engineers to develop their own flight simulator – something that should be well within the capability of many university engineering departments and research organisations. Based on C code modules from an actual flight simulator developed by the author, along with lecture material from lecture series given by the author at Cranfield University and the University of Sheffield Brings together mathematical modeling, computer graphics, real-time software, flight control systems, avionics and simulator validation into one of the faster growing application areas in engineering Features full colour plates of images and photographs. Principles of Flight Simulation will appeal to senior and postgraduate students of system dynamics, flight control systems, avionics and computer graphics, as well as engineers in related disciplines covering mechanical, electrical and computer systems engineering needing to develop simulation facilities.
