In this paper we consider the problem of designing a mixed assembly–disassembly line for remanufacturing. That is, parts from the disassembly and repair of used products can be used to build “new” products. This is a problem common to many OEM remanufacturers, such as Xerox or Kodak. We study two main configurations, under the assumption that the disassembly sequence is exactly the reverse of t...

Ultrathin gold nanowires are unusual colloidal objects that assemble into bundles with line contacts between parallel wires. Each molecule in the contact line interacts with many ligand and solvent molecules. We used X-ray scattering and electron microscopy to study how these interactions control assembly.

We explore judges’ approaches to asylum court appeals based on the issue of conversion from Islam Christianity. Our ethnography in Germany and Austria 2018 2019 provides an insight into how such claims are discussed during appeals. At time, they were increasingly common, especially concerning Iranians Afghans involved ‘free churches’ (e.g. Evangelical, Pentecostal or charismatic). show rumours,...

This paper presents an approach, based on ant techniques, to effectively address the assembly line balancing problem with the complicating factors of parallel workstations, stochastic task durations, and mixed-models. A methodology was inspired by the behavior of social insects in an attempt to distribute tasks among workers so that strategic performance measures are optimized. This methodology...

In this paper, algorithms are presented in order to determine the best disassembly sequence for a sub-assembly and a system life-cycle model for disassembly-assembly line design. The main contribution consists in the determination of a sequence which has the minimal number of components to disassemble, taken into account several criteria: stability, the geometrical form, operations done in para...

Unbalanced assembly line research has grown in importance because of its increasing applications emerging economies, reverse logistics and remanufacturing. This paper examines the performance numerous simulated patterns for reliable unbalanced manual merging lines. The contribution this study to literature is that imbalance does not always negatively impact efficiency it can improve when compar...

This paper presents a component of the on-line tasklevel planning system of the mobile, two-arm robot KAMRO, which is being developed at our Institute. This component generates sequences of explicit robot motions for achieving the goals of elementary assembly operations, and supervises their execution by the real-time robot control system, according to implicitly specified pick-and-place operat...

The formation of zigzags, chevrons, Y-junctions, and line segments is demonstrated in thin films formed from cylindrical morphology silicon-containing conformationally asymmetric rod-coil diblock copolymers triblock terpolymers under solvent annealing. Directed self-assembly the block within trenches yields well-ordered microdomains oriented either parallel or transverse to sidewalls depending ...
