Abstract:
Metagenomics approach involves extraction, sequencing and characterization of the genomic content of entire community of microbes present in a given environment. In contrast to genomic data, accurate assembly of metagenomic sequences is a challenging task. Given the huge volume and the diverse taxonomic origin of metagenomic sequences, direct application of single genome assembly methods on metagenomes are likely to not only lead to an immense increase in requirements of computational infrastructure, but also result in the formation of chimeric contigs. A strategy to address the above challenge would be to partition metagenomic sequence datasets into clusters and assemble separately the sequences in individual clusters using any single-genome assembly method. The current study presents such an approach that uses tetranucleotide usage patterns to first represent sequences as points in a three dimensional (3D) space. The 3D space is subsequently partitioned into "Grids". Sequences within overlapping grids are then progressively assembled using any available assembler. We demonstrate the applicability of the current Grid-Assembly method using various categories of assemblers as well as different simulated metagenomic datasets. Validation results indicate that the Grid-Assembly approach helps in improving the overall quality of assembly, in terms of the purity and volume of the assembled contigs.

The equipment assembled in large steel structure is particular and complex, which must be assembled with a special process plan. Virtual assembly technology provides a feasible idea for equipment assembly. Assembly path planning is the key technology of Virtual assembly. We propose a method of assembly path planning based on the analysis of basic workflow in assembly path planning.

Abstract:
Purpose Many manufacturing sites require precision assembly. Particularly, similar to cell phones, assembly at the sub-mm scale is not easy, even for humans. In addition, the system should assemble each part with adequate force and avoid breaking the circuits with excessive force. The purpose of this study is to assemble high precision components with relatively reasonable vision devices compared to previous studies. Design/methodology/approach This paper presents a vision-force guided precise assembly system using a force sensor and two charge coupled device (CCD) cameras without an expensive 3-dimensional (3D) sensor or computer-aided design model. The system accurately estimates 6 degrees-of-freedom (DOF) poses from a 2D image in real time and assembles parts with the proper force. Findings In this experiment, three connectors are assembled on a printed circuit board. This system obtains high accuracy under 1 mm and 1 degree error, which shows that this system is effective. Originality/value This is a new method for sub-mm assembly using only two CCD cameras and one force sensor.

Abstract:
There are many aspects to consider the good assembly model for Thai wooden furniture. The main idea is the assembly can be made in difference ways. As a result, the easy to assemble means the efficiency to produce. The way how to make an assembly need to be considers. The assembly assessment model is evaluated from the assembly’s method, the assembly’s point, the assembly’s direction, the assembly’s difficulty and the assembly’s motion and time. All these assembly criteria needed to be set to make the assembly easier. Also, part’s size and weight and part’s direction can affect the result of the assembly. With these assembly criteria, Thai’s wooden furniture experts are choosing to select sub-criteria and compare all sub-criteria. Then, the Analytic Hierarchy Process (AHP) is used to calculate the weight of each sub-criterion. With the weight of all sub-criteria when the assessors evaluate the way the assembly makes, the overall score is calculated. The higher overall score means a good assembly model. The second idea is because the assembly can be adjustable and changeable, therefore the assembly’s sequence needed to be considered. The sequence assessment model is developed to calculate the assembly time. The sequence assessment model will use assembly relationship chart and AND/OR graph to set up all the assembly sequence from the beginning to the finished furniture. The smaller assembly time shows the good assembly.

Abstract:
ABSTRACTMultiple subunits of the hepatitis B virus (HBV) core protein (HBc) assemble into an icosahedral capsid that packages the viral pregenomic RNA (pgRNA). The N-terminal domain (NTD) of HBc is sufficient for capsid assembly, in the absence of pgRNA or any other viral or host factors, under conditions of high HBc and/or salt concentrations. The C-terminal domain (CTD) is deemed dispensable for capsid assembly although it is essential for pgRNA packaging. We report here that HBc expressed in a mammalian cell lysate, rabbit reticulocyte lysate (RRL), was able to assemble into capsids when (low-nanomolar) HBc concentrations mimicked those achieved under conditions of viral replicationin vivoand were far below those used previously for capsid assemblyin vitro. Furthermore, at physiologically low HBc concentrations in RRL, the NTD was insufficient for capsid assembly and the CTD was also required. The CTD likely facilitated assembly under these conditions via RNA binding and protein-protein interactions. Moreover, the CTD underwent phosphorylation and dephosphorylation events in RRL similar to those seenin vivowhich regulated capsid assembly. Importantly, the NTD alone also failed to accumulate in mammalian cells, likely resulting from its failure to assemble efficiently. Coexpression of the full-length HBc rescued NTD assembly in RRL as well as NTD expression and assembly in mammalian cells, resulting in the formation of mosaic capsids containing both full-length HBc and the NTD. These results have important implications for HBV assembly during replication and provide a facile cell-free system to study capsid assembly under physiologically relevant conditions, including its modulation by host factors.IMPORTANCEHepatitis B virus (HBV) is an important global human pathogen and the main cause of liver cancer worldwide. An essential component of HBV is the spherical capsid composed of multiple copies of a single protein, the core protein (HBc). We have developed a mammalian cell-free system in which HBc is expressed at physiological (low) concentrations and assembles into capsids under near-physiological conditions. In this cell-free system, as in mammalian cells, capsid assembly depends on the C-terminal domain (CTD) of HBc, in contrast to other assembly systems in which HBc assembles into capsids independently of the CTD under conditions of nonphysiological protein and salt concentrations. Furthermore, the phosphorylation state of the CTD regulates capsid assembly and RNA encapsidation in the cell-free system in a manner similar to that seen in mammalian cells. This system will facilitate detailed studies on capsid assembly and RNA encapsidation under physiological conditions and identification of antiviral agents that target HBc.

Abstract:
ABSTRACT In contrast to other retroviruses, Mason-Pfizer monkey virus (M-PMV) assembles immature capsids in the cytoplasm. We have compared the ability of minimal assembly-competent domains from M-PMV and human immunodeficiency virus type 1 (HIV-1) to assemble in vitro into virus-like particles in the presence and absence of nucleic acids. A fusion protein comprised of the capsid and nucleocapsid domains of Gag (CANC) and its N-terminally modified mutant (ΔProCANC) were used to mimic the assembly of the viral core and immature particles, respectively. In contrast to HIV-1, where CANC assembled efficiently into cylindrical structures, the same domains of M-PMV were assembly incompetent. The addition of RNA or oligonucleotides did not complement this defect. In contrast, the M-PMV ΔProCANC molecule was able to assemble into spherical particles, while that of HIV-1 formed both spheres and cylinders. For M-PMV, the addition of purified RNA increased the efficiency with which ΔProCANC formed spherical particles both in terms of the overall amount and the numbers of completed spheres. The amount of RNA incorporated was determined, and for both rRNA and MS2-RNA, quantities similar to that of genomic RNA were encapsidated. Oligonucleotides also stimulated assembly; however, they were incorporated into ΔProCANC spherical particles in trace amounts that could not serve as a stoichiometric structural component for assembly. Thus, oligonucleotides may, through a transient interaction, induce conformational changes that facilitate assembly, while longer RNAs appear to facilitate the complete assembly of spherical particles.

Abstract:
SUMMARY FtsZ, a bacterial homolog of tubulin, is well established as forming the cytoskeletal framework for the cytokinetic ring. Recent work has shown that purified FtsZ, in the absence of any other division proteins, can assemble Z rings when incorporated inside tubular liposomes. Moreover, these artificial Z rings can generate a constriction force, demonstrating that FtsZ is its own force generator. Here we review light microscope observations of how Z rings assemble in bacteria. Assembly begins with long-pitch helices that condense into the Z ring. Once formed, the Z ring can transition to short-pitch helices that are suggestive of its structure. FtsZ assembles in vitro into short protofilaments that are ∼30 subunits long. We present models for how these protofilaments might be further assembled into the Z ring. We discuss recent experiments on assembly dynamics of FtsZ in vitro, with particular attention to how two regulatory proteins, SulA and MinC, inhibit assembly. Recent efforts to develop antibacterial drugs that target FtsZ are reviewed. Finally, we discuss evidence of how FtsZ generates a constriction force: by protofilament bending into a curved conformation.

Abstract:
In this paper we demonstrate the power of a model of tile self-assembly based on active glues which can dynamically change state. We formulate the Signal-passing Tile Assembly Model (STAM), based on the model of Padilla et al. [24] to be asynchronous, allowing any action of turning a glue on or off, attaching a new tile, or breaking apart an assembly to happen in any order. Within this highly generalized model we provide three new solutions to tile self-assembly problems that have been addressed within the abstract Tile Assembly Model and its variants, showing that signal passing tiles allow for substantial improvement across multiple complexity metrics. Our first result utilizes a recursive assembly process to achieve tile-type efficient assembly of linear structures, using provably fewer tile types than what is possible in standard tile assembly models. Our second system of signal-passing tiles simulates any Turing machine with high fuel efficiency by using only a constant number of tiles per computation step. Our third system assembles the discrete Sierpinski triangle, demonstrating that this pattern can be strictly self-assembled within the STAM. This result is of particular interest in that it is known that this pattern cannot self-assemble within a number of well studied tile self-assembly models. Notably, all of our constructions are at temperature 1, further demonstrating that signal-passing confers the power to bypass many restrictions found in standard tile assembly models.

Abstract:
ABSTRACT Expression of the retroviral Gag protein leads to formation of virus-like particles in mammalian cells. In vitro and in vivo experiments show that nucleic acid is also required for particle assembly. However, several studies have demonstrated that chimeric proteins in which the nucleocapsid domain of Gag is replaced by a leucine zipper motif can also assemble efficiently in mammalian cells. We have now analyzed assembly by chimeric proteins in which nucleocapsid of human immunodeficiency virus type 1 (HIV-1) Gag is replaced by either a dimerizing or a trimerizing zipper. Both proteins assemble well in human 293T cells; the released particles lack detectable RNA. The proteins can coassemble into particles together with full-length, wild-type Gag. We purified these proteins from bacterial lysates. These recombinant “Gag-Zipper” proteins are oligomeric in solution and do not assemble unless cofactors are added; either nucleic acid or inositol phosphates (IPs) can promote particle assembly. When mixed with one equivalent of IPs (which do not support assembly of wild-type Gag), the “dimerizing” Gag-Zipper protein misassembles into very small particles, while the “trimerizing” protein assembles correctly. However, addition of both IPs and nucleic acid leads to correct assembly of all three proteins; the “dimerizing” Gag-Zipper protein also assembles correctly if inositol hexakisphosphate is supplemented with other polyanions. We suggest that correct assembly requires both oligomeric association at the C terminus of Gag and neutralization of positive charges near its N terminus.

Abstract:
It is difficult to assemble micro parts jointing with given space angle as the parts assembled are not on the same flat and the visual depth of microscopic vision is small, which can cause the images gathered by the microscopic vision unintelligible and feature extraction difficult. For the problem, this paper presents an assembly method of micro parts based on projection matching. It can assemble micro parts jointing with given space angle accurately. Firstly, an ideal assembly model is established as the size of the micro parts through the drawing software. Secondly, a graphics algorithm based on the primitive information from CAD is designed. Thirdly, according to the pixel value calibration and the graphics algorithm, the projection pictures are shown on the control interface. Lastly, the control method of micro parts is proposed to assemble them with given space angle. And we accomplished an assembly experiment of micro-tube and micro-column in this way, whose assembly deviation is 0.12[Formula: see text]. Experiment results indicate that the angle between two micro parts assembled can be controlled within the given deviation.

Abstract:
The thesis project was the vehicle for an investigation of prefabrication, assembly, and the design of a lived space. Elements are separated from the building and from each other. This separation is both physically and functionally significant. This separation of elements is presented as the architecture of a joint. The wall is divided into two parts: exterior and interior; creating a wall that is analogous to a double wall system. The exterior wall is the weather barrier, while the interior wall houses the functional necessities for a building, and the extremities of lived spaces. The gap, or joint, is exploited for its ability to be a transportation system. The joint is both vertical and horizontal, separating inside from outside and one unit from the other. The clarity of elements and the method of construction articulates the joint. A well designed element is fabricated and brought to the site. Its independence in construction is a metaphor for the element's ability to stand alone with its architecture, and when assembled underlines the strengths of the unit. The unit presented is one investigation of the varying possibilities of assembly.

Abstract:
This thesis addresses two important aspects of automatic assembly viz., assembly sequence planning and assembly path planning. These issues are addressed separately starting with sequence planning followed by assembly path planning. For efficient assembly without feedback systems (or, passive assembly), an assembler should know the ideal orientation of each component and the order in which to put the parts together (or, assembly sequence). A heuristic is presented to find the optimal assembly sequence and prescribe the orientation of the components for a minimum set of grippers = ideally one. The heuristic utilizes an index of difficulty (ID) that quantifies assembly. The ID for each task in the assembly process is computed on the basis of a number of geometrical and operational properties. The objective of the optimization problem here is to minimize the assembly ID and categorize parts/subassemblies based on their preferred direction of assembly while allowing re-orientation of the base part. It is assumed that the preferred direction of assembly is vertically downward, consistent with manual as well as most automatic assembly protocols. Our attempt is to minimize the number of degrees of freedom required in a re-orienting fixture and derive the requirements for such a fixture. The assembly of a small engine is used as an example in this study due to the variety of ideally rigid parts involved. In high precision assembly tasks, contact motion is common and often desirable. This entails a careful study of contact states of the parts being assembled. Recognition of contact states is crucial in planning and executing contact motion plans due to inevitable uncertainties. Dr. Jing Xiao of UNCC introduced the concept of principal contacts (PC) and contact formation (CF) for contact state recognition. The concept of using CFs (as sets of PCs) has the inherent advantage that a change of CF is often coincident with a discontinuity of the general contact force (force and torque). Previous work in contact motion planning has shown that contact information at the level of PCs along with the sensed location and force information is often sufficient for planning high precision assembly operations. In this thesis, we present results from experiments involving planned contact motions to validate the notion of PCs and CFs -- an abrupt change in general contact force often accompanies a change between CFs. We are only concerned with solving the 2D peg-in-corner problem.

Biology creates assemblies with orders of magnitude more parts than any known human designed process. Molecular biology functions on the premise that fundamental building blocks assemble into chains, are zipped into strands and folded into structures. This thesis is a macroscale implementation that aims to do the same, assemble, zip and fold, in an inorganic system. This system, Zipped, utilizes distributed coalescence of parts, aiming for faster assembly while incorporating error correction into the fabrication process. This thesis presents a design for 0-dimensional building blocks that snap together to form 1-dimensional strands. Strands zip together, interlocking to form 2-dimensional beams that can branch and merge to create patterns or flat sheets. Strands can zip to each other out of plane as well, allowing 3-dimensional construction.
All steps of the construction process are reversible; parts can be assembled, dis-assembled and re-assembled without damage to the part or altering structural performance. No energy, formwork or pre-load is required to maintain the parts position once it is assembled. The system can assemble rigid as well as flexural elements, including chains and revolute joints. Increased stiffness or flexibility can be designed into structures by changing strand geometry and zipping. This ability to tune local structural properties allows actuators to be added to the construction system and form mechanisms. Zipped pieces are demonstrated as the structural element for a robot's body, which can locomote on itself or foreign terrain. Initial studies also demonstrate automated construction with this system. The fundamental principles of this system are demonstrated in many materials, via different manufacturing processes and across several scales, showing applicability to a diverse scenario space.
For ease of fabrication and lab use a centimeter scale part was selected and several thousand parts were manufactured. This 0-dimensional part is presented and used to form larger scale assemblies which are mechanically characterized. From here, mission architectures and real-world applications are described. The Zipped system enables human-scale, controlled and reversible assembly, zipping and folding. This allows reusability, reconfigurability and universality - attributes we often credit to nature.

Abstract:
The project investigates an aesthetic of assembly. It established a visual expression though exploring the relationship between disassembly and assembly in the context of laminated timbers. These explorations are manifested in a learning institution in relationship to an existing CLT factor in Långshyttan. The project becomes a dynamic celebration of assembly and a continuous learning environment as the building continues to disassemble and reassemble to counter the obsolescent of new technological inventions in a rapidly developing industry driven by industrialization and technological determination.  The new building feeds of the factory for purely disassembled parts in terms of discarded waste and a pure form of assembly in terms of unprocessed CLT blanks. The production of industrial produced mass timber elements has further moved the production of buildings into factories and the erection of buildings at site consist primarily of an assembly of  predesigned parts. Architectural advancements is inseparable from technological paradigms and the production of construction timber should carry with it new architectural expressions.

Abstract:
We present methods for distributed self-assembly that utilize simple rule-of-thumb control and communication schemes providing probabilistic performance guarantees. These methods represents a staunch departure from existing approaches that require more sophisticated control and communication, but provide deterministic guarantees. In particular, we show that even under severe communication restrictions, any assembly described by an acyclic weighted graph can be assembled with a rule set that is linear in the number of nodes contained in the desired assembly graph. We introduce the concept of stochastic stability to the self-assembly problem and show that stochastic stability of desirable configurations can be exploited to provide probabilistic performance guarantees for the process. Relaxation of the communication restrictions allows simple approaches giving deterministic guarantees. We establish a clear relationship between availability of communication and convergence properties. We consider Self-assembly tasks for the cases of many and few agents as well as large and small assembly goals. We analyze sensitivity of the presented process to communication errors as well as ill-intentioned agents. We discuss convergence rates of the presented process and directions for improving them.

Abstract:
Analytical engineering design is a global activity requiring efficient global distribution of analytical models of dynamic physical systems through computer networks. Finite Element Method (FEM) models are used globally to analyze the response of physical systems assembled from physical components. FEM models from different physical component suppliers often have geometrically incompatible meshes. This geometric incompatibility of mesh node placement typically requires component internal details in the assembly process. The modular model assembly introduced in this paper does not require such component internal details. It assembles incompatible finite element component models fast and with accuracy comparable to traditional reformulation. The proprietary geometry and material component details are not revealed during the assembly. Modular model assembly can be used to assemble distributed component models through the internet in global engineering design. Dynamic examples are provided.

Abstract:
Engineering design is evolving into a global strategy that distributes model information through computer networks. This strategy requires companies to provide dynamic models of supplied components. Component models must be assembled to obtain the product dynamic model. Four characteristics are needed. Specifically, models require a unique standard format, the exchange of model information must be executed in a single-query transmission, the models must describe only external behavior, and the assembly process must be recursive. The Modular Modeling Method (MMM) [1], is a model assembly algorithm that satisfies these requirements. The MMM algorithm assembles linear physical systems models with dynamic stiffness matrices. This paper will extend MMM to nonlinear affine behavior. In an affine system, deviations in the inputs and outputs exhibit a proportional relationship, but the outputs of the system are not zero at zero input [2]. The main reason for developing a process to assemble affine systems is the possibility of using this method to assemble general differentiable nonlinear physical system models performing around a constant operating point.

Abstract:
Engineering design is evolving into a global strategy that distributes model information through computer networks. This strategy requires companies to provide dynamic models of supplied physical components. Component models are transmitted through the Internet to a common location and then assembled to obtain a product dynamic model. Internet connection permitting, real-time, automated assembly of models requires four characteristics. Specifically, physical models must have a unique standard format, the exchange of model information must be executed in a single-query transmission, the models must describe only external behavior, and the assembly process must be recursive. The Modular Modeling Method (MMM) is an energy based model distribution and assembly algorithm that satisfies these four requirements. The MMM distributes and assembles linear and affine physical systems models using dynamic matrices. Though the MMM procedure can be used for a large class of systems, the dynamic matrices cannot be used to represent nonlinear behavior. A more general nonlinear model representation is required. This work is an extension of the MMM algorithm to assemble physical systems models characterized by analytic nonlinearities. This is a more general procedure that uses Volterra transfer functions to represent nonlinear behavior. Any analytic nonlinear system can be represented through a Volterra model. The reason why we use Volterra models instead ODEs is because Volterra models are only in function of input and output variables. This characteristic facilitates their use in an energy based model assembly method such as the MMM procedure. A procedure to assemble standard Volterra models using conservation energy principle is described. Even though there are extensive literature about gluing models, these techniques do not have all the characteristics needed by the MMM procedure. Using the approach proposed here, complex model assemblies can be executed recursively while hiding the topology and characteristics of their structural model subassemblies.

Full text
Abstract:
We propose metrics for evaluating the performance of robotically assembled discrete cellular lattice structures (referred to as digital materials) by defining a set of tools used to evaluate how the assembly system impacts the achievable performance objective of relative stiffness. We show that mass-specific stiffness can be described by the dependencies E*(γ, D(n, f, RA)), where E* is specific modulus, γ is lattice topology, and the allowable acceptance of the joint interface, D, is defined by an error budget analysis that incorporates the scale of the structure, and/or number of discrete components assembled, n, the type of robotic assembler, RA, and the static error contributions due to tolerance stack-up in the specified assembler structural loop, and the dynamic error limitations of the assembler operating at specified assembly rates, f. We refer to three primary physical robotic construction system topologies defined by the relationship between their configuration workspace, and the global configuration space: global robotic assembler (GR), mobile robotic assembler (MR), and relative robotic assemblers (RR), each exhibiting varying sensitivity to static, and dynamic error accumulation. Results of this analysis inform an iterative machine design process where final desired material performance is used to define robotic assembly system design parameters.

Abstract:
Abstract MEMS structures can be assembled using the surface tension of molten solder (solder self-assembly). Until this novel development, solder self-assembly was performed at the wafer or chip level where the whole chip needed to be heated to melt the micro sized solder droplets used to assemble devices. In this paper we present the design, testing, and modeling of a resistive point heater that is used to assemble an individual device on a chip without affecting neighboring devices. The point heater was packaged in 14 and 24 pin ceramic dual inline packages and tested in air, nitrogen, and formic-acid/nitrogen vapor. The lowest power needed to liquify a 63Sn/37Pb, 8 mil diameter equivalent volume solder droplet and assemble a device in formic-acid/nitrogen vapor was found to be 714 mW. The average power, of several trials, required to liquify a solder droplet is 998 mW at 141 mA and 7.08 V. A steady-state heat transfer model predicts 986.4 mW is required to keep the droplet at 181 °C (the observed minimum temperature at which 63Sn/37Pb solder is in liquid state). Growth of pure Sn platey crystals, varified by X-ray flourescence, was noted on the point heater assembly and surroundings during assembly in formic-acid/nitrogen vapor.

Abstract:
From an industry and organization point of view, this paper considers the assembly systems with one assembler and multi-manufacturer under a revenue-sharing contract in a fuzzy environment which will contribute new insights to the engineering management. Market demand and assembler’s assemble capacity are characterized as fuzzy variables, respectively. Game theory is used to analyze the behavior of the members in the assembly systems. Both non-cooperative game and cooperative game models between the assembler and manufacturers are constructed. The coalition optimal solution of cooperative game model is obtained. The property of the contract is proved. Finally, the two kinds of settings are compared. The conclusion proposed is convenient to refer by the decision maker in engineering management.

Abstract:
In the past decades, firms have increased automated assembly operation to improve productivity and reduce human errors; however, manual assembling is still a necessary operation for complex and large-scaled systems that require high reliability. Furthermore, since customers demand more variety in systems, firms increasingly assemble variants of a system in a single assembly line. In this mixed model assembling operation, there are higher chances of assembly errors due to interchanging of geometrically similar parts between system variants. Design for Assembly (DFA) is a design guideline that assists engineers to design systems that are easier to assemble; however, DFA does not provide any guideline for simultaneously designing variants of system being assembled in mixed model operation. Furthermore, incentive schemes for assembly operators that may influence both assembly productivity and errors have not been the scope of DFA research. In this research, the authors conducted assembling experiments with students to investigate how non-geometric part information and incentive schemes affect the assembly productivity and quality in mixed model assembling operation.
