Woodchuck hepatitis virus (WHV) is prone to aberrant assembly in vitro and can form a broad distribution of oversized particles. Characterizing aberrant assembly products is challenging because they are both large and heterogeneous. In this work, charge detection mass spectrometry (CDMS) is used to measure the distribution of WHV assembly products. CDMS is a single-particle technique where the ...

Modeling of products is undergone a final stage of integration in these years. In this paper, the authors discuss an integrated modeling method for robot assembly of products as a contribution to methodology for integrated robot model systems. Advanced product modeling uses feature and associativity definitions for description of engineering related objects in part models instead of simple geom...

Although solid models play a central role in modern CAD systems, 2D CAD systems are still commonly used for designing products without complex curved faces. Therefore, an important task is to convert 2D drawings to solid models, and this is usually carried out manually even in present CAD systems. Many methods have been proposed to automatically convert orthographic part drawings of solid objec...

In the first paper of this two-part series, the assembly variant design system architecture and complementary assembly methodology have been presented. The general complementary assembly models, hierarchical assembly model and relational assembly model, are established which were further specified as assembly variants model (AVM) and assembly mating graphs (AMG) respectively to cater for the ne...

The manufacturing of complex products often involves the assembly of other products, or sub-assemblies. Furthermore, these sub-assemblies may be manufactured by different suppliers. As a result, the specification of the assembly process for the final product contains relationships between multiple supply chain components, including business entities, manufacturing processes, products, and parts...

Abstract Nowadays, end customers require personalized products to match their specific needs. Thus, production systems must be extremely flexible. Companies typically exploit assembly lines manufacture produces in great volumes. The development of distinguished by mixed or multi models increases flexibility concerning the number product variants able manufactured. However, few scientific contri...

Bio-inspired products and devices take their inspiration from nature [Gold00]. Current mechanical engineering curricula do not cover manufacturing techniques and principles needed to develop such products and devices. We have been enhancing the mechanical engineering undergraduate curriculum by integrating recent advances in the manufacturing of bioinspired products and devices through the foll...

Mixed-model assembly line (MMAL) is a type of production line where a variety of product models similar to product characteristics are assembled. Line balancing and model sequencing problems are important for an efficient use of such lines. This paper presents integer programming formulation and a solution for a loading and assembly plan selection problem in a mixed-model assembly system. The p...
