It was one of the first specialized factories for the production of wheel loaders. Wheel loaders have been produced by the factory for about 20 years, and it has formed the Wild Ox brand 13 ton small and medium-sized loader series. These products sell well展开更多

On the basis of engineering database, parametric drawing of longitudinal and cross section of engine can be obtained from this mode. The model is significant for improving the efficiency and quality of engine general system design. (Author abstract) 6 Refs.展开更多

Data and examples are used to justify how software itself is often poor, how the engineering of software leaves much to be desired, and how research in software engineering has not made enough progress to help overcome these weaknesses. However, these data and examples are presented and interpreted in ways that are arguably imbalanced. This imbalance, usually taken at face value, may be distracting the field from making significant progress towards improving the effective engineering of software, a goal the entire community shares. Research dichotomies, which tend to pit one approach against another, often subtly hint that there is a best way to engineer software or a best way to perform research on software. This, too, may be distracting the field from important classes of progress.展开更多
