Résumé :

This paper deals with shape optimization of three-dimensional elastic bodies. The proposed approach is based on natural design variables and shape functions and utilizes the boundary element method. The design variables are the magnitudes of a set of fictitious loads applied on the structure. Shape optimal design problems based on minimum mean compliance, peak stress minimization and stress constraints are considered. A general method for shape design sensitivity analysis using the material derivative concept and adjoint variable method is used. The sensitivity formula for a general stress constraint imposed over the optimized boundary is derived. Optimal shapes for three-dimensional problems are presented to show numerical applications.

Résumé :

Abstract Elastomers are increasingly used in specialized engineering applications where their complex shape often requires a detailed stress analysis. Specialized programmes have to be used for incompressible materials such as elastomers, since the standard computer finite element packages are unable to give accurate solutions for rubbers with Poisson's ratio close to 0.5. The present paper uses an established finite difference method to examine the deflected shape of rubbers under hydrostatic pressure. A particular case of a rubber cylinder subjected to hydrostatic pressure is examined, where a natural tendency is to assume that the rubber cylinder will reduce slightly in volume, evenly all the way round. However, by performing a detailed finite difference analysis, it was found that the final shape, under pressure, was dependent on the value of Poisson's ratio, and height to diameter ratio of the rubber cylinder. An interesting result is that the end of the cylinder, and the circumferential surface will change shape from a concave to a convex surface by changing the value of ν for certain cylindrical shapes of rubber.

Résumé :

Spar platforms with cylindrical shape and constant cross-section area may experience resonant heave motions in sea states with long peak periods, which are probably excessive for riser integrity due to its low damping and relatively low natural heave period. Changes to hull shape and cross-section that produce more benign heave behavior were discussed by some researchers in the past. In this study, the viscous damping of spar structures is explicitly calculated, and incorporated to the potential solution. It is concluded that the heave resonant response can be considerably reduced by alternative hull shapes via increased damping mechanism and the natural heave period being kept outside the range of the wave energy.

This entails either dividing the shape containing it into smaller shapes, or substituting a variable or terminal for it. For visualization purposes every terminal is associated with a color, and its shape is filled with that color. We show pictures generated with random context picture grammars, then concentrate on grammars which use forbidding context only and present a shrinking lemma for the corresponding languages.

Résumé :

To help students in solving the linear equations in one variable, teacher can use a learning media such as algebra tiles. Algebra tiles are square and rectangle-shaped tiles that represent numbers and variables. Algebra tiles consist of three different-size pieces. The smallest tile is square shape and represents ± 1, the other tile is rectangular shape and represents ± x and the largest tile is large square shape that represents ± x2. The pieces are usually colour-coded so that one colour represents positive values and another color represents negative values. This research is a best practice that was conducted at class VII.7 SMPN 18 Tangerang. The aim of this research is to describe how the algebra tiles supports students’ understanding in solving linear equations in one variable. The competence achievement indicators are: modelling algebraic expressions using algebra tiles; solving linear equations in one variable using algebra tiles; solving linear equations in one variable without use algebra tiles. Data collection through photos, videos, worksheet and students’ work. Students did reducing and balancing ways to find the simple form of algebra tiles. The purpose of reducing or balancing of both sides of linear equations in one variable is to get how many square tiles that equals to one rectangular tile. Algebra tiles made students to be easier in solving linear equations in one variable. Students were very happy to learn mathematics using algebra tiles. The algebra tiles supports students’ understanding in solving linear equations in one variable.

Résumé :

This paper presents a systematic exposition of the general structure of visual constancies and illusions, including the introduction of a number of conceptual distinctions, illustrated by many examples. The study of these phenomena involves the distal, the proximal, and the phenomenal domain. The relations of concordance and discordance between pairs of domains are defined, followed by the definitions of four visual modes (concordant, proximal, constancy, illusion) as particular constellations of concordance-discordance relations between all three domains. Constancies and illusions are characterized by proximal-phenomenal discordance. Attributes of entities of visual domains are divided into the geometric (size, shape, location, orientation) and the photometric (reflectance, illumination) class. The phenomenal domain involves two types of attributes, one group distally and the other proximally focused. Research on both constancies and illusions can be described as involving the study of the effects of two independent variables on a dependent variable. The first independent variable (target variable) is a distal attribute, such as size, shape etc. In constancy studies, the second independent variable (confound variable), is a variable such as distance, orientation etc, that, together with the confound variable, affects the corresponding proximal variable (such as proximal size, shape etc). In illusion studies, confound variables do not affect the proximal variables, but do affect the corresponding phenomenal variables. The main part of the paper consists in the descriptions of studies of constancies and illusions of size, shape, location, orientation, and achromatic and chromatic color, all presented in a common format, which facilitates the comparison of their similarities and differences. The importance of presentation conditions (full-cue versus reduced cue) and instruction type (distally versus proximally focused) is stressed. Finally, salient cases are pointed out in which relations between phenomenal variables tend to take a form qualitatively similar to the relation of the corresponding non-phenomenal variables.

Résumé :

This paper deals with the issue of the perceptual aspects of selected graphic variables (specifically shape and size) and map background in cartographic visualization. The continued experimental study is based on previous findings and the presupposed cross-cultural universality of shape and size as a graphic variable. The results bring a new perspective on the usage of shape, size and presence/absence of background as graphic variables, as well as a comparison to previous studies. The results suggest that all examined variables influence the speed of processing. Respondents (Czech and Chinese, N = 69) identified target stimuli faster without a map background, with larger stimuli, and with triangular and circular shapes. Czech respondents were universally faster than Chinese respondents. The implications of our research were discussed, and further directions were outlined.

Résumé :

Recently the high strength steel has been applied in the automotive more and more widely. In this study, the effect of blank shape on the formability of an automotive part was analyzed. The three kinds of blank shapes were chosen, including a rectangular shaped blank, a blank with two corners cut straightly and a blank with two corners cut in curve. The effect of the variable blank holder force on the formability was studied. The four kinds of variable blank holder force were applied. The blank shape in this part is the blank with two corners cut curve. The results show that the blank with two corners curve is the most suitable. And the blank holder force from 1000 kN to 1500 kN is the most useful for the formability.

Context is classified as either permitting or forbidding, the former enabling the application of a production, the latter inhibiting it. For visualization purposes every terminal is associated with a color, and its shape filled with that color. We show examples of pictures generated with random context picture grammars. Then we concentrate on grammars which use permitting context only and present a pumping lemma for the corresponding picture sets.

Résumé :

Our previous work suggests that stressors that impact placental vascular growth result in a deformed chorionic surface shape, which reflects an abnormal placental three-dimensional shape. We propose to use variability of placental disk thickness as a reflector of deviations in placental vascular growth at the finer level of the fetal stems. We hypothesize that increased variability of thickness is associated with abnormal chorionic surface shape, but will be a predictor of reduced placental functional efficiency (smaller baby for a given placental weight) independent of shape. These measures may shed light on the mechanisms linking placental growth to risk of adult disease. The sample was drawn from the Pregnancy, Infection and Nutrition Study. In all, 94.6% of the cohort consented to placental examination. Of the 1023 delivered at term, those previously sectioned by the Pathology Department were excluded, leaving 587 (57%) cases with intact placentas that were sliced and photographed. The chorionic surface shape and the shape of a central randomly oriented placental slice were analyzed and measures were compared using correlation. Lower mean placental disk thickness and more variable disk thickness were each strongly and significantly correlated with deformed chorionic plate shapes. More variable disk thickness was strongly correlated with reduced placental efficiency independent of abnormal chorionic surface shape. Variability of placental disk thickness, simple to measure in a single randomly oriented central slice, may be an easily acquired measure that is an independent indicator of lowered placental efficiency, which may in turn program the infant and result in increased risk for development of adult diseases.

Résumé :

One part of the tree, namely the leaves, which grow on the branches, has several types of leaves consisting of 4 shapes, ranging from circular shapes, elongated shapes, and some even have a finger shape. Often we mistake the shapes of these leaves. This study discusses the classification of leaves based the shape of the leaf bones using the Convolutional Neural Network, which is used to classify data that has been labeled using one of the methods, namely supervised learning. The purpose of this method is to classify a variable into the variables that have been listed. The goal is to classify leaves based on leaf shape to implement a Convolutional Neural Network algorithm model for leaf classification based on bone shape, which will produce an accuracy value. Accuracy values are obtained from conducting experiments at the training and trial stages. So it can be concluded using the epochs parameter of 30 and a batch size of 128, using ReLU and Softmax activations. The results obtained for the accuracy value for training are 98.52%, while the validation is 89.06%.

Résumé :

Visualization of geographic variables as spatial objects of size proportional to variable strength is possible via generating cartograms. We developed a methodology based on mathematical morphology to generate contiguous cartograms. This methodology relies on weighted skeletonization by zone of influence. This weighted skeletonization by zone of influence determines the points of contact of multiple frontlines propagating from centroids of various planar sets (states) at the traveling rates depending upon the variable’s strength. The contiguous cartogram generated via this morphology-based algorithm preserves the global shape and local shapes and yields minimal area errors. We generated a cartogram for a population variable to demonstrate the proposed approach. Furthermore, the population cartograms for the United States generated via four other approaches are compared with the morphology-based cartogram in terms of errors with respect to area, local shape, and global shape. This approach for generating cartograms preserves the global shape at the expense of compromising with area errors. It is inferred from the comparative error analysis that the proposed morphology-based approach could be further extended by exploring the applicability of additional characteristics of B, which controls the dilation propagation speed and direction of dilation while performing weighted skeletonization by zone of influence, to minimize the local shape errors and area errors.

In this paper, a series of SMP morphing skins were prepared from hydro-epoxy resin, carboxyl-terminated butadiene acrylonitrile (CTBN) and maleic anhydride. By adjusting molecular weight and content of CTBN, in-plane properties and out-of-plane properties of morphing skins can be adjusted. Due to the in-plane tensile stress acting on the skin during flight, tensile test was carried out to study its in-plane performance. After testing, skin can resist maximum in-plane tensile strength of 63.7 MPa. As for the out-of-plane performance of the skin, shape memory test was studied in this paper. All morphing skins have 100% shape fixity rate (Rf) and fast shape recovery rate (Rr). When toughened by CTBN of 10% of 4000 molecular weight with a mass fraction, the skin can recover its out-of-plane deformed shape in 33 s. The SMP skins were proved to be a promising candidate for morphing skins.

Résumé :

Abstract The reinforcement of soil is used to improve its strength and stiffness. The standard method of soil reinforcement is an application of geosynthetics. Soil reinforcement by distributed discrete fibres represents an alternative to those techniques. Currently used fibres have a straight shape, uniform cross-section, and smooth surface, which is not optimal in terms of the fibre-soil interaction. In this study, fibres with a variable shape were utilized. The fibres were fabricated using a fused deposition modelling technology. Firstly, a brief theoretical background is presented. Then, the proposed shapes of the fibres and their manufacturing process are described. The mechanical properties of the soil-fibre composite were investigated through consolidated drained triaxial tests. Well-graded coarse sand and poorly-graded fine sand were used. A higher peak shear strength was observed in the case of fibres with a variable shape. The effect of the variable shape of the fibres on the peak shear strength was higher in the case of the coarse sand.

Résumé :

Many authors noted in the field research on the models of rigid foundations that a compacted wedge-shaped core of soil is formed with the destruction of the bases, which is a natural extension of the foundation. In the research of the strip foundation model with variable geometric shape of the foundation base, a compaction soil area of spherical shape with a diameter close to the width of the foundation model is found on a sand base. A wedge-shaped core, along the edges of which there has been a shift in mass of the base when achieving the ultimate loading, has been noted in a compaction soil area. The solid part of the foundation base is the compacted wedge-shaped core base, the height of the wedge-shaped core being commensurate with the length of the elements forming the foundation. Identified geometric parameters of compacted core under the foundation base of strip foundation with geometrically variable shape can be used in determining the ultimate bearing capacity of soil of the base for such foundations.
