Streszczenie:

Recent advances on the Web have generated unprecedented opportunities for individuals around the world to assemble into teams. And yet, because of the Web, the nature of teams and how they are assembled has changed radically. Today, many teams are ad hoc, agile, distributed, transient entities that are assembled from a larger primordial network of relationships within virtual communities. These assemblages possess the potential to unleash the high levels of creativity and innovation necessary for productively addressing many of the daunting challenges confronting contemporary society. This article argues that Web science is particularly well suited to help us realize this potential by making a substantial interdisciplinary intellectual investment in (i) advancing theories that explain our socio-technical motivations to form teams, (ii) the development of new analytic methods and models to untangle the unique influences of these motivations on team assembly, (iii) harvesting, curating and leveraging the digital trace data offered by the Web to test our models, and (iv) implementing recommender systems that use insights gleaned from our richer theoretical understanding of the motivations that lead to effective team assembly.

Streszczenie:

Trophic niches condition the energetic performance of species within food webs providing a vital link between food web assembly, species diversity, and functioning of ecosystems. Our understanding of this important link is, however, limited by the lack of empirical tools that can be easily applied to compare entire food webs at regional scales. By comparison, with different a priori synthetic models defined according to specific assembly rules (i.e., purely random, limiting similarity, and niche filtering), we demonstrate that a set of food web properties (trophic richness, evenness, and divergence) are controlled by ecological processes. We further demonstrate that although both limiting similarity and niche filtering are statistically significant assembly processes shaping our studied lake food webs, their relative importance is richness-dependent, and contextual to the specific food web property under consideration. Our results have both important theoretical and practical implications. Theoretically, the observed richness-dependent variation on food web properties contradicts the common criticism on food web theory that food web properties are roughly scale-invariant. Practically, these properties can help avoiding spurious conclusions, while providing useful information for multiple food web niche spaces supporting the ecosystem functioning.

Web Assembly is growing and also the most widely studied area which interests many developers when it comes to performance and speed to make web development fast as ever. When it comes to speed and performance algorithms can perform faster computations. Algorithmic trading executes trade at a faster speed. It can buy and sell stocks within a fraction of milliseconds. However, selecting the right tools and technologies is extremely important in algorithmic trading. There are trading strategies which we can use to optimize our trade and increase the return gained on buying and selling stocks. But, choosing an efficient programming language is substantially important. A programming language with a low latency can leverage the trade. Most commonly used languages for algorithmic trading are C/C++, Java, C#, Python. Speed and performance are an essential factor in algorithmic trading. The main purpose of introducing web Assembly in trading as discussed above is speed and performance. Web Assembly is a low-level binary instruction which can execute any program on the web and it can deliver native like performance on the internet. Using Web Assembly, we can compile any code written in languages like C/C++, C#, Java, and python to wasm (Web Assembly executable file) and run on the browser. Web Assembly was developed by W3C, Mozilla Corporation, and Google.

DNA self-assembly is a nanotechnology that folds DNA into desired shapes. Self-assembled DNA nanostructures, also known as origami, are increasingly valuable in nanomaterial and biosensing applications. Two ways to use DNA nanostructures in medicine are to form nanoarrays, and to work as vehicles in drug delivery. The DNA nanostructures perform well as a biomaterial in these areas because they have spatially addressable and size controllable properties. However, manually designing complementary DNA sequences for self-assembly is a technically demanding and time consuming task, which makes it advantageous for computers to do this job instead. We have developed a web server, FOLDNA, which can automatically design 2D self-assembled DNA nanostructures according to custom pictures and scaffold sequences provided by the users. It is the first web server to provide an entirely automatic design of self-assembled DNA nanostructure, and it takes merely a second to generate comprehensive information for molecular experiments including: scaffold DNA pathways, staple DNA directions, and staple DNA sequences. This program could save as much as several hours in the designing step for each DNA nanostructure. We randomly selected some shapes and corresponding outputs from our server and validated its performance in molecular experiments.

Abstract Accurate modeling of galaxy distributions is paramount for cosmological analysis using galaxy redshift surveys. However, this endeavor is often hindered by the computational complexity of resolving the dark matter halos that host these galaxies. To address this challenge, we propose the development of effective assembly bias models down to small scales, i.e., going beyond the local density dependence capturing non-local cosmic evolution. We introduce a hierarchical cosmic web classification that indirectly captures up to third-order long- and short-range non-local bias terms. This classification system also enables us to maintain positive definite parametric bias expansions. Specifically, we subdivide the traditional cosmic web classification, which is based on the eigenvalues of the tidal field tensor, with an additional classification based on the Hessian matrix of the negative density contrast. We obtain the large-scale dark matter field on a mesh with ~3.9 h -1 Mpc cell side resolution through Augmented Lagrangian Perturbation Theory. To assess the effectiveness of our model, we conduct tests using a reference halo catalogue extracted from the UNIT project simulation, which was run within a cubical volume of 1 h -1 Gpc side. The resulting mock halo catalogs, generated through our approach, exhibit a high level of accuracy in terms of the one-, two- and three-point statistics. They reproduce the reference power-spectrum within better than 2 percent accuracy up to wavenumbers k ~ 0.8 h Mpc-1 and provide accurate bispectra within the scales that are crucial for cosmological analysis. This effective bias approach provides a forward model appropriate for field-level cosmological inference and holds significant potential for facilitating cosmological analysis of galaxy redshift surveys, particularly in the context of projects such as DESI, EUCLID, and LSST.

Assembly is an important part in production and development of complex products. Flexible assembly retrieval is one of the key issues to find the reusable model. The main objective of this paper is to extend the model of ontology-based assembly design for model reuse. Firstly, we propose a representation of assembly structural data including topological structure, assembly semantics, and geometrical information. Secondly, we enrich assembly design (AsD) ontology for knowledge captured and shared in Web Ontology Language 2 Description Logic (OWL 2 DL) and Semantic Web Rule Language (SWRL). And then, we define the matching strategies and similarity assessment for two matched models. Finally, we illustrate the validity of assembly design representation for model reuse through experiments.

Collaborative CAD systems enabling collaboration in computer-aided design processes among distributed designers are gaining more and more attention. Yet, such systems, especially in support of collaborative assembly modeling, are hardly achievable. In an effort to bridge this gap, we are dedicated to developing a collaborative CAD system with aim at 3D assembly modeling. As part of this effort, this paper addresses one function module of the system, a Web-based Product Structure Manager, which enables the Collaborative Product Structure Management (CPSM) in collaborative assembly modeling. In particular, CPSM facilitates product data sharing among distributed designers and supports collaboration in product structure creation and modification. A bench clamp assembly is used as an example to illustrate the Product Structure Manager for supporting collaborative assembly modeling.

Streszczenie:

Assembly precision optimization is an important means to ensure product accuracy, including two aspects: on the one hand, the relevant deviations of out-of-tolerance key characteristics are reduced to the design tolerance range; on the other hand, the deviation fluctuation range of key characteristics with a large process capability index (Cp) can be extended to achieve the balance between accuracy, process capacity, and production cost. By virtue of the accumulated experience, a fast solution can be provided for the out-of-tolerance problem. Therefore, a semantic-based assembly precision optimization method considering process capacity is proposed in this paper. By constructing an ontology model between Cp and optimization strategy, a reasonable assembly precision optimization strategy can be pushed based on product accuracy analysis results. Firstly, an assembly precision optimization semantic model is established by association between analysis results, out-of-tolerance key characteristics, assembly process, and tolerance adjustment defined with Web Ontology Language (OWL) assertions. Furtherly, according to different Cp corresponding to different assembly success rates, Semantics Web Rule Language (SWRL) rules based on Cp are constructed to the push optimization strategy. Finally, the effectiveness of the model is illustrated by an aircraft inner flap.

Community assembly models, usually constructed for food webs, are an important component of our understanding of how ecological communities are formed. However, models for mutualistic community assembly are still needed, especially because these communities are experiencing significant anthropogenic disturbances that affect their biodiversity. Here, we present a unique network model that simulates the colonization and extinction process of mutualistic community assembly. We generate regional source pools of species interaction networks on the basis of statistical properties reported in the literature. We develop a dynamic synchronous Boolean framework to simulate, with few free parameters, the dynamics of new mutualistic community formation from the regional source pool. This approach allows us to deterministically map out every possible trajectory of community formation. This level of detail is rarely observed in other analytic approaches and allows for thorough analysis of the dynamical properties of community formation. As for food web assembly, we find that the number of stable communities is quite low, and the composition of the source pool influences the abundance and nature of community outcomes. However, in contrast to food web assembly, stable mutualistic communities form rapidly. Small communities with minor fluctuations in species presence/absence (self-similar limit cycles) are the most common community outcome. The unique application of this Boolean network approach to the study of mutualistic community assembly offers a great opportunity to improve our understanding of these critical communities.

We implement a cryptographic library using Web Assembly. Web Assembly is expected to show better performance than Javascript. The proposed library provides comprehensive algorithm sets including revised CHAM, Hash Message Authentication Code (HMAC), and ECDH using the NIST P-256 curve to provide confidentiality, data authentication, and key agreement functions. To optimize the performance of revised CHAM in the proposed library, we apply an existing method that is a four-round combining method and additionally propose the precomputation method to CHAM-64/128. The proposed revised CHAM showed an approximate 2.06 times (CHAM-64/128), approximate 2.13 times (CHAM-128/128), and approximate 2.63 times (CHAM-128/256) performance improvement in Web Assembly compared to JavaScript. In addition, CHAM-64/128 applying the precomputation method showed an improved performance by approximately 1.2 times more than the existing CHAM-64/128. For the ECDH using P-256 curve, the naive implementation of ECDH is vulnerable to side-channel attacks (SCA), e.g., simple power analysis (SPA), and timing analysis (TA). Thus, we apply an SPA and TA resistant scalar multiplication method, which is a core operation in ECDH. We present atomic block-based scalar multiplication by revising the previous work. Existing atomic blocks show a performance overhead of 55%, 23%, and 37%, but atomic blocks proposed to use only P=(X,Y,Z) show 18%, 6%, and 11% performance overhead. The proposed Web Assembly-based crypto library provides enhanced performance and resistance against SCA thus, it can be used in various web-based applications.

ABSTRACT The internal properties of dark matter haloes correlate with the large-scale halo clustering strength at fixed halo mass – an effect known as assembly bias – and are also strongly affected by the local, non-linear cosmic web. Characterizing a halo’s local web environment by its tidal anisotropy α at scales approximately four times the halo radius, we demonstrate that these multiscale correlations represent two distinct statistical links: one between the internal property and α, and the other between α and large-scale (${\gtrsim}30\, h^{-1}\, {\rm Mpc}$) halo bias b1. We focus on scalar internal properties of haloes related to formation time (concentration cvir), shape (mass ellipsoid asphericity c/a), velocity dispersion structure (velocity ellipsoid asphericity cv/av and velocity anisotropy β), and angular momentum (dimensionless spin λ) in the mass range $8\times 10^{11}\lesssim M_{\rm vir}/(\, h^{-1}\, \mathrm{M}_{\odot })\lesssim 5\times 10^{14}$. Using conditional correlation coefficients and other detailed tests, we show that the joint distribution of α, b1, and any of the internal properties c ∈ {β, cv/av, c/a, cvir, λ} is consistent with p(α, b1, c) ≃ p(α)p(b1|α)p(c|α), at all but the largest masses. Thus, the assembly bias trends c↔b1 reflect the two fundamental correlations c↔α and b1↔α. Our results are unaffected by the exclusion of haloes with recent major merger events or splashback objects, although the latter are distinguished by the fact that α does not explain their assembly bias trends. The overarching importance of α provides a new perspective on the nature of assembly bias of distinct haloes, with potential ramifications for incorporating realistic assembly bias effects into mock catalogues of future large-scale structure surveys and for detecting galaxy assembly bias.

In this study, Japanese cedar (Cryptomeria japonica (L. f.) D. Don) harvested from a plantation in Taiwan was used to develop built-up beams using self-tapping screws as metal connectors and resorcinol formaldehyde resin as glue to assemble components based on various assembly configurations. Results showed that adding glue provided flexural rigidity, whereas assembly using self-tapping screws resulted in built-up beams with high ductility but relatively low flexural bearing capacity. Beams used glue exhibited approximately linear behavior, whereas those using only screws exhibited some undulating and stepwise responses, implying that shear force between the flanges and the web may cause buckling as well as the dislocation of the self-tapping screws. When using components of similar grades, adding another web can improve the performance. Furthermore, the grades of flanges can strongly influence the flexural load-bearing capacity. In addition, a smaller spacing between the screws can improve the flexural load-bearing performance, but also cause wooden components to crack. Typical bending failure modes were observed in the developed built-up beams, indicating tension failure of the bottom flange as well as slippage between flanges and the web due to horizontal shear, which also caused buckling deformations in the screws.

The Academic Information System (in Indonesian often abbreviated as SIAKAD) is a system developed to manage student data that aims at facilitating online academic administration activities. It aims to provide academic information services in the form of web applications, where teachers can independently create student academic reports to synchronize data into the DAPODIK system, a primary education data system, and develop academic information systems using web assembly according to user experience (UX) and developer experience (DX). The research method consists of field studies and literature related to web assembly, primary education data (DAPODIK), and the Academic Information System (SIAKAD). This information system and database were built using the Convention Over Configuration paradigm. The design phase used a prototyping model to graphically represent the system workflow and used an experimental research approach. Moreover, the study used an integrated modeling language (UML), and a Database Management System using PostgreSQL, and alpha testing for model testing. The Client Application was built using the C# programming language for users to generate student academic reports every semester. Processing data transactions using web assembly took less time than the traditional web, which was less than 300 milliseconds.

An assemblability evaluation system of products including parts and subassemblies was presented. The necessity about assemblability evaluation for subassemblies was discussed. A subassembly-centered product assemblability analysis method was proposed. The two-step assemblability analysis flow including process step and entire step about subassembly was designed, which can analyze structure of subassembly when it was assembled and fitted on product. A web-based prototype system of subassembly-centered product assimilability evaluation which supports multi-sited collaborative design was developed with Java/JSP, which integrated with the platform of collaborative assembly planning and collaborative assembly simulation. Finally, an example was used to validate reasonability of subassembly assemblability analysis method and the effectiveness of the evaluation system.

AbstractThis paper presents our research on developing an ontology-based framework that can represent morphological characteristics related to assembly joints. Joints within the physical structure of an assembly are inevitable because of the limitations of component geometries and the associated, required engineering properties. Consequently, a framework is needed that can capture and propagate assembly design and joint information in a robust assembly model throughout the entire product development processes. The framework and model are based on an understanding of the morphological characteristics of an assembly and its different physical effects. The morphological characteristics are consequences of the principal physical processes and of the design intentions. Therefore, the morphological characteristics should be carefully represented while considering the geometry and topology of assembly joints. In this research, assembly joint topology is defined by a mereotopology, which is a region-based theory for the parts and associated concepts. This formal ontology can differentiate often ambiguous assembly and joining relations. Furthermore, the mereotopological definitions for assembly joints are implemented in Semantic Web Rule Language (SWRL) rules and Web Ontology Language triples. This process provides universality to the mereotopological definitions. Two geometrically and topologically similar joint pairs are presented to describe how the assembly joints can be defined in mereotopology and be transformed into SWRL rules. Web3D is also employed to support network-enabled sharing of assembly geometry. Finally, the proposed modeling framework is demonstrated using a real fixture assembly. This case study demonstrates the usability of the proposed framework for network-based design collaboration.

Nowadays, the concept of industry 4.0 frequently occur in the literature. The digitalization of manufacturing grows rapidly. The basic structure of the approach is to transform the hardware and equipment in the manufacturing into intelligent elements that communicate each other. In this study, based on the idea of intelligent equipment; we propose to transform traditional power screwdrivers into smart devices that communicate with various IoT applications or cloud applications by including electronic cards and software components. Our approach aims to minimize the percentage of human error in the manufacturing process. There are four main elements in our system. These are Web/Cloud Server, NGP Operator panels, RF I/O card and power screwdriver RF card. All these elements communicate with each other. The overall working principle of the system is briefly as follows. There is a database on the Web/Cloud Server. In this database, there are job parameters related to the assembly ID(CIS) number which defined for each assembly job. Various operations to be performed according to the assembly ID(CIS) number are defined in detail in the database, for example, for power screwdrivers, the number of tightening information is defined on a rule-based basis. With the Web API developed in C# language, the web/cloud server communicates with the linux computer that executes the NGP operator panel. When an assembly job starts, if the assembly ID(CIS) number matches the stock definition, then the relevant transaction data is retrieved from the web server and displayed on the NGP operator panel. The front-end software on the NGP operator panel was developed using Microsoft.NET and compiled using Mono Framework to support Linux OS. As soon as an assembly job starts, the number of screws to be tightened determined according to the assembly ID(CIS) related rules. After that, the gun MAC (TMAC) address information is transmitted from the NGP operator panel to the RF I/O Card via RS232 serial port communication. The ZigBee protocol carries the information about how many screws will be tightened from the RF I/O Card to the Gun RF card mounted on power screwdriver. A special RF based protocol developed for that purpose. By means of our proposed protocol, "OK" or "Not OK" information is sent to the RF I/O card of the NGP operator panel every time the operator performs the tightening operation. With the bidirectional RS232 serial port communication, an information message is returned for each completed operation to the NGP operator panel via the RF I/O card. When all the operations related to the assembly ID(CIS) number are completed, the relevant data is transmitted over the Web Server API and recorded in the database, and the assembly life cycle is completed. This study demonstrates how traditional power screwdrivers may be transformed into an IoT-enabled smart manufacturing device without extensive modification. Thanks to the proposed solution, the digital transformation of traditional devices will be affordable and applicable to many different manufacturing tools.

Reconfigurable manufacturing systems (RMS) can be used to produce micro-assembled products that are too complex for assembly on flat substrates like printed circuit boards. The greatest advantage of RMS is their capability to reuse machine parts for different products, which enhances the economical efficiency of quickly changing or highly individualized products. However, often, process engineers struggle to achieve the full potential of RMS due to product designs not being suited for their given system. Guaranteeing a better fit cannot be done by static guidelines because the higher degree of freedom would make them too complex. Therefore, a new method for generating dynamic guidelines is proposed. The method consists of a model, with which designers can create a simplified assembly sequence of their product idea, and another model, with which process engineers can describe the RMS and the procedures and operations that it can offer. By combining both, a list of possible machine configurations for an RMS can be generated as an automated response for a modeled assembly sequence. With the planning tool for micro-assembly, an implementation of this method as a modern web application is shown, which uses a real existent RMS for micro-assembly.

Abstract Summary: Combinatorial assembly of DNA elements is an efficient method for building large-scale synthetic pathways from standardized, reusable components. These methods are particularly useful because they enable assembly of multiple DNA fragments in one reaction, at the cost of requiring that each fragment satisfies design constraints. We developed BioPartsBuilder as a biologist-friendly web tool to design biological parts that are compatible with DNA combinatorial assembly methods, such as Golden Gate and related methods. It retrieves biological sequences, enforces compliance with assembly design standards and provides a fabrication plan for each fragment. Availability and implementation: BioPartsBuilder is accessible at http://public.biopartsbuilder.org and an Amazon Web Services image is available from the AWS Market Place (AMI ID: ami-508acf38).

Spiders are nature’s engineers that build lightweight and high-performance web architectures often several times their size and with very few supports; however, little is known about web mechanics and geometries throughout construction, especially for three-dimensional (3D) spider webs. In this work, we investigate the structure and mechanics for a Tidarren sisyphoides spider web at varying stages of construction. This is accomplished by imaging, modeling, and simulations throughout the web-building process to capture changes in the natural web geometry and the mechanical properties. We show that the foundation of the web geometry, strength, and functionality is created during the first 2 d of construction, after which the spider reinforces the existing network with limited expansion of the structure within the frame. A better understanding of the biological and mechanical performance of the 3D spider web under construction could inspire sustainable robust and resilient fiber networks, complex materials, structures, scaffolding, and self-assembly strategies for hierarchical structures and inspire additive manufacturing methods such as 3D printing as well as inspire artistic and architectural and engineering applications.

Meltblown nonwovens have been produced as 2D web structures for a variety of end uses. Investigation into the development of 3D structures, has led to the integration of meltblown and robotic technology to form the Robotic Fiber Assembly and Control System. The effect of curvature of the collecting surface on the structural properties of the webs such as the diameter and orientation distributions of the fibers and the pore size distribution on the webs has been investigated. The relative frequency of fibers oriented in the machine direction increased significantly when the curvature of the collecting surface increased, while the average pore size of the web decreases due to the increased orientation of fibers in the direction of collection.

The restructuring of our commission, adopted at the last General Assembly, was undoubtedly beneficial and various activities were developed under the aegis of the commission.Two very important changes have marked the last triennium: the World Wide Web and electronic publishing. The American Astronomical Society is the first to have introduced an electronic version of an astronomical journal and will be followed soon by the Astronomy and Astrophysics Journal. Last February, an ICSU/UNESCO Conference was held in Paris on this topic. A.G. Hearn was the IAU representative. An extensive report of this meeting can also be found on the Web (http://astro.fys.ruu.nl:8000/iau) and the proceedings are available also on the Web (http://www.lmcp.jussieu.fr/icsu/Information/index.html. A Joint Discussion on this very hot topic will be held during the Kyoto General Assembly.

In this work, a formex procedure is presented in order to provide a conceptually consistent method of formex formulation in the context of substructure analysis. Grids composed of beams with multiple web openings are treated for which substructuring is well suited. An open web beam can be regarded as an assembly of typical units. Formex formulations are produced for such typical units and for the whole assembly. The concepts of plenices are also employed in order to organise a suitable system for a formex representation of partitioned configurations. Also, a formex function is introduced which makes it possible to generate some distorted configurations from regular patterns. A reader with no familiarity with formex algebra may wish to consult Ref. 2 or Ref. 6 for a brief sketch of formex algebra and Ref. 7 for a quick reference on plenices.

An ideal product modeling system should support both part modeling and assembly modeling, instead of just either of them as is the case in most current CAD systems. A good basis for such integration is multiple-view feature modeling, as it allows focusing on different aspects of the product, while at the same time maintaining consistency of all model views. This paper presents a framework that supports synchronous collaborative sessions via Internet, among members of a distributed development team, with such a modeling system. The framework provides facilities for creating a hierarchical product structure, with single and compound components, and meanwhile assigning tasks to team members. The actual design of a single component is supported by a web-client specialized in part design, whereas the specification of assembly relations among components is supported by a web-client specialized in assembly design. All clients make use of the same server, which runs a multiple-view feature modeling system and maintains the complete product model, guaranteeing consistency of the part design and the assembly design views.

The knowledge about Ford’s manufacturing processes is contained in an ontology originally developed using the KL-ONE representation language and methodology. To preserve the viability of the GSPAS ontology and to make it easily usable for other applications within Ford, we needed to re-engineer and convert the KL-ONE ontology into a semantic web OWL/RDF format.
