This paper investigates the problems of cylinder fitting in laser scanning three-dimensional Point Cloud Data (PCD). Most existing methods require full cylinder data, do not study the presence of outliers, and are not statistically robust. But especially mobile laser scanning often has incomplete data, as street poles for example are only scanned from the road. Moreover, existence of outliers i...

Over the past years software architecture has become an important sub-field of software engineering. There has been substantial advancement in developing new technical approaches to start handling architectural design as an engineering discipline. Measurement is an essential part of any engineering discipline. Quantifying the quality attributes of the software architecture will reveal good insi...

The satisfying of human needs through designing technical objects requires the compromisation and settling of various conflicting criteria at different stages of the engineering design process. The need for back and forth adjustment of design specifications, concept finding, and design embodiment can be considered to be carried out in a telescopic review fashion. The present study is concerned ...

Assessment of quality of object oriented software during design phase has been a prime objective among researchers in software engineering discipline. There are many available tools that offer the software product quality from its code. Unfortunately, assessment of design quality has been more of a theoretical issue and the software engineering market lacks readily available tools for this purp...

in this paper a new strategy is proposed to design a fixed-structure robust controller for a flexible beam.  robust controller designed by the conventional  loop­ shaping method is not appropriate for a beam because of its high order and complicated form. fixed-structure  loop shaping control in conjunction with particle swarm optimization (pso)algorithm  is used to overcome this drawback. the ...

As feature sizes shrink to deep sub-micron, the performance of VLSI chips becomes dominated by the interconnect delay. In a traditional top-down design ow, logic synthesis algorithms optimize gate area or delay without accurate interconnect delay because of lack of physical design information. Thus, the e ectiveness of the optimization techniques is limited. We integrate logic synthesis and phy...

This paper considers simultaneous fitting of multiple curves and surfaces to 3D measured data captured as part of a reverse engineering process, where constraints exist between the parameters of the curves or surfaces. Enforcing such constraints may be necessary (i) to produce models to sufficiently accurate tolerances for import into a CAD system, and (ii) to produce models which successfully ...

Robust beamforming is a commonly-used solution to various array processing problems. Recently, with the inevitable and rapid increasing of size, complexity issue arising from high-dimension matrix computations has become an urgent concern in algorithm design. In this paper, efficient distributed robust developed for large-scale arrays. Specifically, problem minimum variance distortionless respo...

The design of microbial production processes relies on rational choices for metabolic engineering of the production host and the process conditions. These require a systematic and quantitative understanding of cellular regulation. Therefore, a novel method for dynamic flux identification using quantitative metabolomics and (13)C labeling to identify piecewise-affine (PWA) flux functions has bee...
