While the first six chapters are basically the same as those found in the earlier edition  with some minor corrections  the majority of the change involves the advanced materials found in chapters 7-13  since more educators  practicing engineers and scientists are now aware of bond graphs than were in the early 1970s. Included in the area of new and advanced topics are: multiport fields and junction structures; transducers  amplifiers  and instruments; magnetic circuits and devices; and nonlinear simulation.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45647859187765,"sku":"ByrdShop_0471621714","price":70.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9780471621713.jpg?v=1781698383","url":"https:\/\/atxbooks.com\/products\/system-dynamics-a-unified-approach-2nd-edition-9780471621713","provider":"ATX Books","version":"1.0","type":"link"}
