Full textAbstract:
The clypeasteroid echinoid skeleton is a multi-plated, light-weight shell construction produced by biomineralization processes. In shell constructions, joints between individual elements are considered as weak points, yet these echinoid skeletons show an extensive preservation potential in both Recent and fossil environments. The remarkable strength of the test is achieved by skeletal reinforcement structures and their constructional layouts. Micro-computed tomography and scanning electron microscopy are used for microstructural and volumetric analyses of the echinoid's skeleton. It is shown that strengthening mechanisms act on different hierarchical levels from the overall shape of the skeleton to skeletal interlocking. The tight-fitting and interlocking plate joints lead to a shell considered to behave as a monolithic structure. The plate's architecture features distinct regions interpreted as a significant load-transferring system. The internal support system follows the segmentation of the remaining skeleton, where sutural layout and stereom distribution are designed for effective load transfer. The structural analysis of the multi-plated, yet monolithic skeleton of Echinocyamus pusillus reveals new aspects of the micro-morphology and its structural relevance for the load-bearing behaviour. The analysed structural principles allow E. pusillus to be considered as a role model for the development of multi-element, light-weight shell constructions.

Full textAbstract:
The skeleton of Echinocyamus pusillus is considered as an exceptional model organism for structural strength and skeletal integrity within the echinoids as demonstrated by the absence of supportive collagenous fibres between single plates and the high preservation potential of their skeletons. The structural principles behind this remarkably stable, multi-plated, light-weight construction remain hardly explored. In this study, high-resolution X-ray micro-computed tomography, finite-element analysis and physical crushing tests are used to examine the structural mechanisms of this echinoid's skeleton. The virtual model of E. pusillus shows that the material is heterogeneously distributed with high material accumulations in the internal buttress system and at the plate boundaries. Finite-element analysis indicates that the heterogeneous material distribution has no effect on the skeleton's strength. This numerical approach also demonstrates that the internal buttress system is of high significance for the overall skeletal stability of this flattened echinoid. Results of the finite-element analyses with respect to the buttress importance were evaluated by physical crushing tests. These uniaxial compression experiments support the results of the simulation analysis. Additionally, the crushing tests demonstrate that organic tissues do not significantly contribute to the skeletal stability. The strength of the echinoid shell, hence, predominantly relies on the structural design.

Full textAbstract:
Skeleton and Infill (SI) housing system is considered as a significant path of sustainably prolonging building life by improving structural durability and infill variability for its nature that the skeleton system is fixed, while the infill system could be rebuilt to satisfy users’ changing demands in different stage without damaging the skeleton system. The application of a SI housing system involves two new characteristics compared to traditional cast-in-place housing system: components production in factories and site construction are carried out simultaneously; the skeleton system and the infill system are constructed in parallel phases, which increase enormous parallel work. Iterations and rework would increase with the improper handling of parallel works, which lead to higher construction cost and lower participant willingness of stakeholders in SI housing construction delivery process. It is essential to establish a model to clarify the dependencies among major parallel work items and recognize parallel work sets to optimize the construction sequence for stakeholders to strengthen communication and coordination on key work items in a more efficiency way. By conducting investigations into the construction delivery process of typical SI housing projects in China, this paper developed a parallel collaborative mode based on the design structure matrix (DSM) to identify the complex dependencies among major cooperative work items. Furthermore, to provide an optimized parallel collaborative process, graph theory was introduced to find parallel work sets and eliminate repetition and iteration caused by improper work execution sequences. The results provide a guide for stakeholders to make appropriate cooperation strategies in implementing major work items and promoting cooperating efficiency by reducing iteration and rework.

Introduction: a spatial development reference skeleton model is proposed for solving problems of settlement development. The model is necessary for improving rural settlement planning, renovation and reforming. Constituents of the territorial settlement reference skeleton were considered. The research aims at the practical approval of a rural settlement skeleton integrated assessment.
Materials and methods: open cartographic sources, territorial planning documents, information from the National Statistical Committee of the Republic of Belarus were studied. The methodological basis of the research consists of such general scientific methods as a system approach and comparative analysis method as well as a particular interdisciplinary method of cartographic simulation using geographic information systems.
Results: features of Mahilyow region reference skeleton were revealed. The reference skeleton includes the historical and cultural, natural and ecological, transport and communication, and settling constituents. The necessary and sufficient criteria for obtaining the integrated assessment of rural settlement reference skeleton are substantiated. That allows determining the strategic directions of sustainable territorial development. Based on the integrated assessment, the cartogram of the settlement potential of Mahilyow region of the Republic of Belarus was compiled. Generalization of the obtained results allows formulating some recommendations for town planning to determine the strategic lines of Mahilyow region sustainable development subject to the rural settlement prospects.
Conclusions: the research shows that the application of system approach and a cartographic modelling of the territorial settlement reference skeleton is a useful tool for assessing the rural settlement skeleton. Further research is conceived in the development of prospective models of settling, natural and ecological, historical and cultural, transport and communication skeletons.

Full textAbstract:
In this study, it is aimed to present a point of view regarding the behaviour of construction systems implemented in traditional Turkish architecture against earthquakes. In the scope of the study, examples of civil architecture were considered and their structures were evaluated as building elements such as foundation, wall and flooring. Traditional Turkish architecture construction systems can be evaluated in two parts. One of them is the wooden carcass system and the other is the unreinforced masonry system. In the wooden carcass system, the carrier is the load bearing elements used in horizontal and vertical directions. Intermediate parts (strut, diagonal etc.) are placed between these elements to form triangles. The triangles (strut, diagonal) used in the wooden skeleton system comprise highly resistant forms against earthquakes. Moreover, due to the internal structure and physical properties of the wood, which is the skeleton material, the flexibility that it maintains can meet the lateral loads of earthquakes. The second construction system which is the system addressed in this application, is the unreinforced masonry system. In this system, the loadbearing system itself is the walls, which are not resistant to lateral loads. In order to provide this flexibility beams (hatıllar) are installed at certain intervals. After the wall is built to a certain height, a different material is laid allowing a plane of movement on the wall. Thus, when the wall is exposed to a lateral load, it escapes from the planes where the beams (hatıllar) are present, and is protected against large damages by absorbing the earthquake load. In order to establish that the foundation of the structure can withstand earthquakes by movement, wood is placed at the lower part of the foundation above a layer of sand ensuring lateral movement and flexibility of the building. In traditional buildings the slabs are connected to the building walls with beams (hatıllar). Through the agency of the beams (hatıllar) formed at the connection points, the slabs can act as a mass so that they can meet the earthquake load. Allowing the structure to move makes it resistant to earthquakes, seismic isolators are used for this purpose by absorbing the earthquake load and moving the foundation of the structure.

Full textAbstract:
Successful dispersal of freshwater sponges depends on the formation of dormant sponge bodies (gemmules) under adverse conditions. Gemmule formation allows the sponge to overcome critical environmental conditions, for example, desiccation or freezing, and to re-establish as a fully developed sponge when conditions are more favorable. A key process in sponge development from hatched gemmules is the construction of the silica skeleton. Silica spicules form the structural support for the three-dimensional filtration system the sponge uses to filter food particles from ambient water. We studied the effect of different hypergravity forces (1, 2.5, 5, 10, and 20 × g for 48 h)—as measure for environmental stress—on the ability of developing sponges to set-up their spiculous skeleton. Additionally, we assessed whether the addition of nutrients (i.e., dissolved 13C- and 15N-labeled amino acids) compensates for this stress. Our results show that freshwater sponges can withstand prolonged periods of hypergravity exposure and successfully set-up their skeleton, even after 48 h under 20 × g. Developing sponges were found to take up and assimilate dissolved food before forming a functional filtering system. However, fed and non-fed sponges showed no differences in skeleton formation and relative surface area growth, suggesting that the gemmules’ intrinsic energy fulfills the processes of skeleton construction. Additionally, non-fed sponges formed oscula significantly more often than fed sponges, especially under higher g-forces. This suggests that the eventual formation of a filtration system might be stimulated by food deprivation and environmentally stressful conditions. These findings indicate that the process of spiculous skeleton formation is energy-efficient and highly resilient. The uptake of dissolved food substances by freshwater sponges may contribute to the cycling of dissolved organic matter in freshwater ecosystems where sponges are abundant.

Full textAbstract:
In designing cubature buildings, an important stage is the selection of an appropriate construction solution, depending on the intended use and location of the designed building. When selecting the load-bearing structures, the designers strive to ensure that the structure weighs as little as possible, while meeting the strength conditions and ensuring the safe operation of the building. The article compares the load-bearing systems of the steel structure of a one-nave hall due to the economy of execution and meeting the ULS and SLS conditions. The analysis was carried out on four types of transverse system, including three frame systems with tendons and for a frame system with a lattice transom of the “N” type. Static calculations as well as dimensioning and optimization of the transverse load-bearing structures were performed in RFEM program, modelling the hall structure in 3D.

Full textAbstract:
A concise synthetic approach to [5/5/6] tricyclic pyrrolidine core of dendrobine is reported. This methodology relies on the construction of β-hydroxylactams by NaBH4-I2 reduction followed by reaction of allylsilane with the aid of Lewis acid to generate alkenyl lactams in good yields. Further, ring-opening metathesis (ROM) followed by ring-closing metathesis (RCM) were used to assemble the [5/5/6] aza-tricyclic skeleton of dendrobine. This short synthetic route has been expanded to assemble tricyclic [5/5/8] system with pentenylboronic acid.

This chapter describes major structures built from 1890 to 1897, many of which featured wind-braced frames that used steel to reduce spatially inefficient masonry walls and piers. Before the late nineteenth century, wind bracing had rarely been more than a minor consideration in structural calculations—the dead weight of brick or stone construction could absorb all but the most severe wind forces. However, the lighter weight of skeletal buildings, their increased height, and the unreliable nature of iron connections brought this issue to the fore. Chicago's tall building designers of the 1880s were among the first to recognize this problem and to solve it with dedicated lateral-resistant systems.

Full textAbstract:
In chapter 5, we studied the responses of chemical species in a reaction system to pulse perturbations and showed the deduction of direct, causal connectivities by chemical reactions—the reaction pathway—and the reaction mechanism from such measurements. The causal connectivites give the information on how the chemical species are connected by chemical reactions. In this chapter we turn to another source of information about chemical species in a reaction system, that of correlations among the species. Correlations of concentrations are measures of the statistical dependence of the concentration of one species on that of one or more of the other species in the system. Such correlations can be determined from measurements of time series of concentrations collected around a stationary state (nonequilibrium or equilibrium). We shall show that from concentration correlations it is possible to construct a skeletal diagram of the reaction system that gives a graphical measure of strong control and regulatory structure in reaction networks, gives some information on connectivity, leads to information on the reaction pathway and mechanism, and may simplify the analysis of such networks by identifying possible, nearly separable subsystems. We begin with the demonstration and explanation of this approach by analyzing some abstract reaction models. In chapter 8 we show the utility of this “correlation metric construction” (CMC) with application to time-series measurements on a part of glycolysis, and in chapter 13 on an extensive genome study. Consider a chemical system as shown in fig. 7.1. Mechanisms of this type are common in biochemical networks. For example, the subnetwork of fig. 7.1 containing S3 to S5 is based on a simple model of fructose interconversion in glycolysis and the subnetwork composed of S6 to S7 is similar to the phosphorylation/dephosphorylation cycles found in cyclic cascades. As an aside, this mechanism performs the function of a biochemical NAND gate, another example of a chemical computational function (see chapter 4).

The chapter describes a brief history of the emergence of the theory of cellular automata, their main properties, and methods for constructing. The image skeletonization methods based on the Euler zero differential are described. The advantages of using hexagonal coverage for detecting moving objects in the image are shown. The software and hardware implementation of the developed methods are presented. Based on the obtained results, a hexagonal-coated cellular automata was developed to identify images of objects based on the Radon transform. The method and mathematical model of the selection of characteristic features for the selection of the skeleton and implementation on cellular automata with a hexagonal coating are described. The Radon transform allowed to effectively extract the characteristic features of images with a large percentage of noise. An experiment for different images with different noises was conducted. Experimental analysis showed the advantages of the proposed methods of image processing and extraction of characteristic features.

[2] Raster motion paths are replaced by offset spiral-like paths, which are discussed in this paper. Most commercial CAD/CAM packages are feature-based, and their use requires the effort and expertise of the user. The shape has to be decomposed into manufacturing features before the software packages can generate the paths. [3] Path planning has long been studied as discussed in this paper. There are still some problems associated with the previous algorithms and also assumptions are usually made. [6, 7, 27] An algorithm for directly generating offset edges, which can be developed to be the deposition paths, is presented in this paper. The skeleton of a layer or a slice of a 3-D CAD drawing is first generated. Based on that skeleton, the offset edges are incrementally constructed. This paper focuses on the characteristics of skeleton and offset edges as well as the construction algorithm for those edges. Simulations are used to verify this method.

The paper proposes a mathematical model of the concept of grapheme, the main purposes of which are to formulate a strict definition of the concept of «grapheme» and to highlight the overall structure of images of the same characters. The construction of the grapheme is based on a continuous skeletal approach, which involves the construction of the skeleton of a binary image of the symbol with its subsequent regularization. We also use the constructed model for the problem of text recognition on a digital image. For this purpose, features based on vertex positions in the grapheme model are extracted from the model, and the classifier is trained on these features. It determines which class the grapheme selected from the binary image of one symbol belongs to. We also consider the method of processing the input image with text for better selection of characters, lines and words. The experiments show the performance of the proposed grapheme model. The classification algorithm shows results comparable with modern methods of text recognition.

<p>As a new type of structural system, hybrid masonry (HM) structure with reinforced concrete (RC) frame is constructed of reinforced block masonry wall and reinforced concrete frame. This structural system combines the advantages of reinforced concrete frame structure and reinforced concrete block masonry structure, also overcomes some limitations of them. In order to study the seismic performance of the structural system, the lateral reversed cyclic loading experiment on the HM structure with RC frame was conducted. In the experiment, two specimens that were constructed with different connecting type were designed and tested, in one of them the masonry blocks was separated from the RC frame and only connected with steel keys at the top part of the specimen, while in the other there was no spacing between the RC frame and the masonry blocks. According to the data of the experiment, the paper analyzed the failure process and patterns, hysteretic characteristic, skeleton curve, stiffness degradation and displacement ductility of the structural system, and compared the results of the two specimens. The experimental study indicated that the HM structure with RC frame showed extraordinary good seismic performance during testing, and this form of construction had fairly good displacement ductility and energy dissipation, which would provide a basis for further theoretical analysis and design method.</p>

Full textAbstract:
Being the only flying mammal, bats have evolved unique flight devices affording them high maneuverability and efficiency despite their low flight speeds. By selecting bats of three different ecological niches — a highly efficient fishing bat, a nimble insectivorous forager, and a large soaring bat of the ‘flying fox’ family — passive wing shapes can be demonstrated as capable of attaining very different aerodynamic performance characteristics. The aerodynamics of man-made equivalents to these wing shapes, using thin airfoils rather than skeleton and membrane construction, are studied both computationally through a lifting-line approach and experimentally with quasistatic wind tunnel data of ‘morphed’ and ‘unmorphed’ wing shapes. Results confirm that shape inspired by the larger soaring bat has higher lift-to-drag ratios, while that of the foraging bat maintains lift at higher angles of attack than the other wings. The advantages are more pronounced by morphing, increasing both lift coefficient and lift-to-drag ratios by up to 50% for certain wings. This is validated both numerically and in the Cornell University 4′×4′ wind tunnel. Analysis of these shapes provides the first phase of wing design for use on a morphing aircraft vehicle. In order to take greater advantage of vehicle morphing, wing shapes with camber and twist distributions unique from those found in nature will evolve to suit a man-made structure. In this way, a wing shape intended for cruise may extend its practicality into highly maneuverable operations through the use of wing morphing. Starting from the bat planform shapes, a series of optimizations determines the best camber and twist distributions for effective morphing. Given a fixed degree of shape change at any point along an airfoil based on mechanism constraints, improved morphing performance can be found compared to initial assumptions of the natural shape change. Heuristic optimization employing simulated annealing determines the required morphing shapes for increased performance, broadening the abilities of each wing shape by increasing parameters such as lift, rolling moment, and endurance.
