We discuss the self-assembly system of triangular tiles instead of square tiles, in particular right triangular tiles and equilateral triangular tiles. We show that the triangular tile assembly system, either deterministic or non-deterministic, has the same power to the square tile assembly system in computation, which is Turing universal. By providing counter-examples, we show that the triangu...

Achieving an appropriate assembly sequence needs deep verification for its physical feasibility. For this purpose, industrial engineers use several assembly predicates; namely, liaison, geometric feasibility, stability and mechanical feasibility. However, testing an assembly sequence for these predicates requires huge assembly information. Extracting such assembly information from an assembled ...

In order to find an optimum assembly sequence in engineering design domain, a knowledge-based virtual assembly approach was put forward. Virtual assembly design environment was also introduced, and knowledge representation models for virtual assembly rules and cases are introduced and studied respectively. A side-center virtual assembly method was applied to avoid the occurrence of assembly int...

Self-assembly of proteins on lipid membranes underlies many important processes in cell biology, such as, exo- and endo-cytosis, assembly viruses, etc.

In the process of aircraft assembly, various parts have an important impact on among which fasteners play role in affecting stability assembly and service life aircraft. Standardized fastener installation surface quality affect quality. Proper guaranteed are conducive to reducing risk assembly. However, characteristics standard need be studied urgently. This paper analyzes parts, information co...

Purpose – This paper aims to investigate automatic assembly planning for robot and manual assembly. Design/methodology/approach – The octree decomposition technique is applied to approximate CAD models with an octree representation which are then used to generate robot and manual assembly plans. An assembly planning system able to generate assembly plans was developed to build these prototype m...

The NCBI Assembly database (www.ncbi.nlm.nih.gov/assembly/) provides stable accessioning and data tracking for genome assembly data. The model underlying the database can accommodate a range of assembly structures, including sets of unordered contig or scaffold sequences, bacterial genomes consisting of a single complete chromosome, or complex structures such as a human genome with modeled alle...

Stochastic analysis of superresolution microscopy data obtained from receptor trafficking on neurons reveals novel organized molecular assembly generating long range forces. Would that have been possible with single particle tracking? How have we characterized these molecular assemblies?
