We propose a general formulation, called Multi-X, for multi-class multi-instance model fitting – the problem of interpreting the input data as a mixture of noisy observations originating from multiple instances of multiple classes. We extend the commonly used α-expansion-based technique with a new move in the label space. The move replaces a set of labels with the corresponding density mode in ...

Municipal engineering is an important infrastructure that supports normal production and life of the city. With the development of urbanization, its characteristics of comprehensiveness and complexity emerge increasingly and its importance requires each public work to have a high standard of quality. In this paper, we studied the evaluation problems for quality evaluation of municipal engineeri...

Highly proficient expert engineers begin the iterative process of design by thoroughly investigating problem. Engineering students are often distracted surface details, leading to a faulty conception problem and inappropriate solution strategies. Adequate problem-scoping is arguably most important step in process. To address this issue, researchers developed an instructional framework help teac...

abstract water retention curve (wrc) is a fundamental property of soil. it is used to evaluate available water, permeability, drainage and movement of solutes. despite numerous studies on wrc of soils abroad, no local study has been carried out on charmahal-va-bakhtiari soils. the objective of this study was to compare the quality of fitting of several wrc models to lordegan soils and to select...

This paper introduces an index for assessing the flexibility of candidate engineering designs and manufacturing processes at various stages during product realization. Once the process flexibility index (Cf) is defined, several examples of its use are provided in metal cutting, metal forming, and injection molding. The definition of the process flexibility index: resembles the process capabilit...

Many theoretical and practical problems arise at different stages of the design/manufacturing process during development of a pump. The experience obtained in pump development proves that the quality of a pump depends on many factors, which should he satisfied to receive good results. At the same time, the theory of engineering design principles exists, which is applicable to designing various ...

Freeform feature fitting is a technique underlying different applications, including reverse engineering, object recognition and conceptual shape design. The latter application poses specific requirements to the fitting technique with regard to speed, robustness and interactivity. On the other hand, the spatial accuracy and the density of the input data can be permitted to be relatively low. We...
