Engineering modeling is the art of reducing a physical system to a mathematical description in order to analyze system performance Unlike many familiar problems in mathematics and engineering, the problem of producing a mathematical model for a given system does not possess a unique solution Many models of various degrees of complexity and detail can be derived for any physical system, and the selection of the right model for a given purpose can at times seem a bit overwhelming The concepts of usefulness and simplicity outlined in the quotes above prove to be helpful guides when faced with such a challenge As the quotes above suggest, the goal is rarely to create the most detailed or realistic model conceivable, but instead to produce a representation that captures the details of interest in a simple, concise manner Transforming a system from physical reality to a set of equations invariably involves some simpli cation in the description and some uncertainty in the measurement or calculation of model parameters Since it is therefore impossible to reproduce the physical system perfectly in the mathematical world, the proper evaluation of a model s quality is really an evaluation of its usefulness and not its detail The operative question thus becomes: can the model explain the behavior it was developed to explain to the degree of accuracy desired Given a choice among models that pass this test of usefulness, there are often advantages to using the simplest possible representation These advantages stem not from computational ef ciency (after all, many commercially available computer codes allow the engineer to build multibody dynamic models of cam-follower systems that are more complex than those discussed here), but rather from the engineering insight provided by simple models Often, simple models enable the engineer to develop analytical results that save time in the design process Instead of running a battery of simulations on a complex model to see how the frequency of an oscillation in the system varies with the length of one element, a simple model could provide an algebraic relationship indicating that the frequency changes with the square root of the length Simple models also enable the engineer to apply intuition from very simple systems (for instance, the idealized mass-springdamper) to more complex systems (such as an automotive valve train) The danger is that the model will be too simple and some relevant behavior will be ignored In the design of engineering systems, therefore, different models with varying complexity each have a role to play Complex models offer the comfort of additional completeness and a closer match to experiment while simple models provide intuition and a means of separating primary and secondary effects Knowing which model to use when is indeed a challenge, but one that can be greatly reduced with the help of a few concepts discussed in later sections This chapter provides the basic tools necessary to produce dynamic models of camfollower systems (and many other mechanical systems), simplify the models through some physical arguments, and roughly assess whether or not such models are useful or too simple The models developed may be used to analyze dynamic phenomena (Rothbart, 1956) such as cam hop (where the cam and follower actually separate), the dynamic forces that occur in each component, and the noise generated by the system while in operation The particular modeling approach taken is known as lumped parameter modeling since the physical characteristics of components are combined, or lumped, to produce simpler representations All components of the cam-follower system possess some mass or inertia, exhibit some compliance or spring-like behavior, and dissipate some energy from the system For modeling purposes, it is convenient to separate these effects into a series of. how to extract image from pdf using pdfbox in java: [Solved] Extract images from pdf using pdfbox - CodeProject how to extract image from pdf using itext in java Apache PDFBox Extract Images from PDF Document ...

Total prefabricated bridge systems offer maximum advantages for rapid construction and depend on a range of prefabricated bridge elements that are transported to the work site and assembled in a rapid construction process Prefabricated designs are becoming familiar to the engineers to the extent that they can specify a pre-manufactured bridge in their drawings The supplier will provide a cookie cutter design to satisfy the technical speci cations As the US interstate highway system approaches the end of its service life, urban congestion continues to grow Bridge construction extending over several months has become a primary source of congestion Bridge construction or rehabilitation can be a signi cant source of congestion because of its sequential nature In cast-in-place construction, foundations for piers and abutments must be built rst, then pier columns and caps must be built before beams and decks are placed Offsite prefabrication technologies and processes help solve this problem Ongoing research is focused on identifying and developing new bridge elements and systems for all materials that would help accelerate bridge construction Bridge construction times can be reduced signi cantly by using precast columns Columns can be segmented, post-tensioned, reinforced, hollow, or solid concrete how to print pdf using java swing: Java - printing pdf in network printer - Experts Exchange extract images from pdf java pdfbox Extract Images From PDF Files with Java – IDRsolutions
