Answering this question from a fresh and original perspective, Predrag Cvitanovic takes the reader on the amazing, four-thousand-diagram journey through the theory of Lie groups. This book is the first to systematically develop, explain, and apply diagrammatic projection operators to construct all semi-simple Lie algebras, both classical and exceptional. The invariant tensors are presented in a somewhat unconventional, but in recent years widely used, "birdtracks" notation inspired by the Feynman diagrams of quantum field theory. Notably, invariant tensor diagrams replace algebraic reasoning in carrying out all group-theoretic computations. The diagrammatic approach is particularly effective in evaluating complicated coefficients and group weights, and revealing symmetries hidden by conventional algebraic or index notations. The book covers most topics needed in applications from this new perspective: permutations, Young projection operators, spinorial representations, Casimir operators, and Dynkin indices. Beyond this well-traveled territory, more exotic vistas open up, such as "negative dimensional" relations between various groups and their representations. The most intriguing result of classifying primitive invariants is the emergence of all exceptional Lie groups in a single family, and the attendant pattern of exceptional and classical Lie groups, the so-called Magic Triangle. Written in a lively and personable style, the book is aimed at researchers and graduate students in theoretical physics and mathematics. 606 $aGroup theory 608 $aElectronic books. 615 0$aGroup theory. 676 $a512/.2 686 $aSK 260$2rvk 700 $aCvitanovic?$b Predrag$046041 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910457995303321 996 $aGroup theory$92458606 997 $aUNINA LEADER 03896nam 2200865z- 450 001 9910557614003321 005 20220321 035 $a(CKB)5400000000045262 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/79642 035 $a(oapen)doab79642 035 $a(EXLCZ)995400000000045262 100 $a20202203d2022 |y 0 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aMarine Power Systems 210 $aBasel$cMDPI - Multidisciplinary Digital Publishing Institute$d2022 215 $a1 online resource (238 p.) 311 08$a3-0365-3150-5 311 08$a3-0365-3151-3 330 $aMarine power systems have been designed to be a safer alternative to stationary plants in order to adhere to the regulations of classification societies. Marine steam boilers recently achieved 10 MPa pressure, in comparison to stationary plants, where a typical boiler pressure of 17 MPa was the standard for years. The latest land-based, ultra-supercritical steam boilers reach 25 MPa pressure and 620 °C temperatures, which increases plant efficiency and reduces fuel consumption. There is little chance that such a plant concept could be applied to ships. The reliability of marine power systems has to be higher due to the lack of available spare parts and services that are available for shore power systems. Some systems are still very expensive and are not able to be widely utilized for commercial merchant fleets such as COGAS, mainly due to the high cost of gas turbines. Submarine vehicles are also part of marine power systems, which have to be reliable and accurate in their operation due to their distant control centers. Materials that are used in marine environments are prone to faster corrosive wear, so special care also should be taken in this regard. The main aim of this Special Issue is to discuss the options and possibilities of utilizing energy in a more economical way, taking into account the reliability of such a system in operation. 606 $aHistory of engineering & technology$2bicssc 606 $aTechnology: general issues$2bicssc 610 $aabsorption cooling 610 $aatmospheric drain tank 610 $aCODLAG 610 $acogeneration 610 $acombined cycle 610 $adata-driven modelling 610 $adecay state coefficients 610 $adiesel engine turbocharger 610 $aenergy analysis 610 $aexergy analysis 610 $aexergy destruction 610 $aexergy efficiency 610 $afailure diagnosis 610 $afault tree analysis 610 $aflexible foundation 610 $afuel consumption 610 $agenetic programming 610 $aheating and cooling output 610 $ahydraulic jet 610 $aisolation 610 $ajet parameter 610 $aLNG tanker 610 $amaintenance 610 $amarine diesel engine 610 $amarine propulsion 610 $amarine steam turbine 610 $amechanical failure 610 $aMLP neural network 610 $an/a 610 $aNOx emissions 610 $aoperation efficiency 610 $aoptimization 610 $apropulsion failure 610 $apropulsion failure analysis 610 $apropulsion main engine 610 $areliability 610 $asplit injection 610 $asubmarine cable 610 $atrigeneration energy system 610 $aturbine cylinders 610 $aunderwater vehicle 610 $avibration mitigation 615 7$aHistory of engineering & technology 615 7$aTechnology: general issues 700 $aPoljak$b Igor$4edt$01314877 702 $aPoljak$b Igor$4oth 906 $aBOOK 912 $a9910557614003321 996 $aMarine Power Systems$93032080 997 $aUNINA
