While the self-assembly of different types of DNA origami into well-defined complexes could produce nanostructures on which thousands of locations can be independently functionalized with nanometer-scale precision, current assembly processes have low yields. Biomolecular complex formation requires relatively strong interactions and reversible assembly pathways that prevent kinetic trapping. To ...

This paper presents a European integrated project in the domain of innovative hybrid assembly the combination of self-assembly and robotics. Robotics allows for high precision and flexibility with full control of the assembly process. Self-assembly, on the other hand, offers massively parallel, unsupervised processing and thus provides high throughputs that cannot be reached with simple robotic...

This paper focuses on production systems that consist of multiple parallel assembly lines. The main literature contributions are briefly described and used to present a summary of the state of the art. The advantages and disadvantages of adopting multiple lines are discussed and the multiple assembly line balancing problem and its relevant characteristics are

Aimed at detection of parallel assembly modes, a method for assembly graph construction is described that is based on the systematic generation and analysis of precedence relations and their application to subassembly detection. This method dramatically reduces the search space for detailed analysis and avoids the use of precedence graphs. Copyright © 2002 IFAC

According to researches, one of the productivity barriers among many organizations is assembly line balancing problem, which needs scientific models to be solved. This paper examines the effect of line balancing on the functioning of assembly line in two sections. In the first section, after studying the theoretic bases and reviewing the literature, we have discussed the assembly concepts, diff...

The tile assembly model is a highly distributed parallel model of molecular computation. Plenty of experiments have proved that the simple binary arithmetic could be fulfilled by the process of self-assembly of DNA (deoxyribonucleic acid) tiles. Finite field GF(2 n ) is one of the most commonly used mathematic sets. A DNA computing system was designed based on the tile assembly model and applie...

Job shop scheduling is one of the most explored areas in the last few decades. Although it is very commonly witnessed in real-life situations, very less investigation has been carried out in scheduling operations of multi-level jobs, which undergo serial, parallel, and assembly operations in an assembly job shop. In this work, some of the dispatch rules, which have best performances in scheduli...

ÐThe aromatic diacid residue 4,6-dibenzofuranbispropionic acid (1) was designed to nucleate a parallel b-sheet-like structure in small peptides in aqueous solution via a hydrogen-bonded hydrophobic cluster. Even though a 14-membered ring hydrogen bond necessary for parallel b-sheet formation is favored in simple amides composed of 1, this hydrogen bonding interaction does not appear to be suci...

background; work-related musculoskeletal disorders (wmsds) may involve all parts of the body, and have been a worldwide problem. employed women are two to five times more likely to report such problems, and assembly lines suspected to induce more wmsds because of high rate of repetitive motions. methods;the aim of this study to determine the prevalence of wmsds in women workers of an automobile...

Recent advances in silicon processing and microelectromechanical systems (MEMS) have made possible the production of very large numbers of very small components at very low cost in massively parallel batches. Assembly, in contrast, remains a mostly serial (i.e., nonbatch) technique. In this paper, we argue that massively parallel selfassembly of microparts will be a crucial enabling technology ...
