Abstract:
In this paper we propose a universal data structure (UDS), termed as UDS, which will aid in the design of optimal boundary data structures. We later show, with the aid of some recently published data structures, that any data structure can be expressed as a special case of UDS. We demonstrate how the application of the optimality concepts of the UDS can lead us to the discovery of more efficient data structures than popular data structures. We also discuss two approaches for optimization. We show that a globally optimal data structure is better than a special purpose optimal data structure.

Abstract:
Self-contained structured domains of RNA sequences have often distinct molecular functions. Determining the boundaries of structured domains of a non-coding RNA (ncRNA) is needed for many ncRNA gene finder programs that predict RNA secondary structures in aligned genomes because these methods do not necessarily provide precise information about the boundaries or the location of the RNA structure inside the predicted ncRNA. Even without having a structure prediction, it is of interest to search for structured domains, such as for finding common RNA motifs in RNA-protein binding assays. The precise definition of the boundaries are essential for downstream analyses such as RNA structure modelling, e.g., through covariance models, and RNA structure clustering for the search of common motifs. Such efforts have so far been focused on single sequences, thus here we present a comparison for boundary definition between single sequence and multiple sequence alignments. We also present a novel approach, named RNAbound, for finding the boundaries that are based on probabilities of evolutionarily conserved base pairings. We tested the performance of two different methods on a limited number of Rfam families using the annotated structured RNA regions in the human genome and their multiple sequence alignments created from 14 species. The results show that multiple sequence alignments improve the boundary prediction for branched structures compared to single sequences independent of the chosen method. The actual performance of the two methods differs on single hairpin structures and branched structures. For the RNA families with branched structures, including transfer RNA (tRNA) and small nucleolar RNAs (snoRNAs), RNAbound improves the boundary predictions using multiple sequence alignments to median differences of −6 and −11.5 nucleotides (nts) for left and right boundary, respectively (window size of 200 nts).

Abstract:
Abstract. Aggregation is an important operation for the generalization of land-cover data. However, current research often entails aggregation on a global perspective, which is not conducive to capturing the spatial characteristics of geographic objects with significant spatial structures, i.e., structured geographic objects. Hence this paper proposes an area aggregation method that can maintain the boundary characteristics of the structured geographic objects. First, we identify the structured geographic objects based on the description parameters of the spatial structure. Second, a Miter-type buffer transformation is introduced to extract the boundary of each structured geographic object, and area elements inside the boundary are processed with corresponding aggregation operations. Finally, the boundary of the structured geographic objects and the aggregation result of the area elements are inserted back into the aggregated result of the original land-cover data using the NOT operation. The proposed approach is experimentally validated using geographical condition census data for a city in southern China. The experimental result indicates that the proposed approach not only reasonably identify the typical characteristics of structured geographic objects but also effectively maintains the boundary characteristics of these objects.

Abstract:
Ni3Al is a potentially useful high temperature alloy. In its single crystal form it exhibits good ductility, however in polycrystalline form the pure alloy is highly prone to intergranular failure. It has been seen that in slightly nickel-rich alloys the addition of small amounts of boron has the effect of dramatically increasing the material ductility and of changing the failure mode from intergranular to transgranular. In alloys which have been ductilitized by boron addition, atom probe investigation has shown the boron to be segregated to grain boundaries. This segregation may induce a change in the boundary structure as has been seen by Sickafus and Sass in gold doped iron bicrystals.Small angle boundaries in polycrystals and fabricated bicrystals have been examined using transmission electron microscopy. The bicrystals were produced by hot pressing misoriented single crystals of either pure or doped Ni3Al. Boundaries have been observed in a variety of fabricated bicrystals.

Abstract:
Grain boundary structures in the Accumulative roll-bonding (ARB) processed copper (ARB-Cu) have been studied. The grain boundary structures were observed by high-resolution transmission electron microscopy (HRTEM). In order to clarify the difference between the grain boundaries in ARB-Cu and equilibrium boundaries, calculated atomic structure of symmetric tilt grain boundaries with <110> common axis (<110> symmetric tilt grain boundary; <110> STGB) in Cu were used. The near 14° boundary in the ARB-Cu could be described by the dislocation model, but the dense dislocation region existed near the grain boundary. The high angle boundaries in ARB-Cu could be described by the structural units which were obtained by molecular dynamics (MD) simulation. Furthermore, in the 2 cycles and 6 cycles ARB-Cu (2cARB-Cu and 6cARB-Cu), the deformation twin boundaries could be observed and described by the structural unit. Therefore, it was concluded that the grain boundary structure in the ARB-Cu was not much different from the normal equilibrium grain boundary and explained by conventional dislocation and structural unit models.

Abstract:
Ordered alloys have been of great interest in the last decades for their potential use as high temperature structural materials. The most commonly studied ordered alloys are Ni3 Al, with L12structure, and L1 0TiAl. Grain boundary fragility, however, is a major problem in the practical application of many ordered alloys, although it can be ameliorated in Ni3Al by boron doping. The problem calls for improved understanding of grain boundary structure in ordered alloys. Most studies so far have been done on alloys based on L12 and B2 structure. An investigation of twin boundary structure in L10 CuAu(I) has been carried out in the present work, by means of CTEM and computer image matching techniques.The twins in the present study are order twins; i.e. they are formed upon ordering, when a cubic to tetragonal phase transformation occurs. The lattice strains associated with the cubic-tetragonal transformation are accommodated by a repeated twinning structure which consists of alternating twins on parallel {101) planes, as observed by Pashley and Presland.

Abstract:
Boundary-element methods, also known as panel methods, have been widely used for computations of wave loads and other hydrodynamic characteristics associated with the interactions of offshore structures with waves. In the conventional approach, based on the low-order panel method, the submerged surface of the structure is represented by a large number of small quadrilateral plane elements, and the solution for the velocity potential or source strength is approximated by a constant value on each element. In this paper, we describe two recent developments of the panel method. One is a higher-order method where the submerged surface can be represented exactly, or approximated to a high degree of accuracy by B-splines, and the velocity potential is also approximated by B-splines. This technique, which was first used in the research code HIPAN, has now been extended and implemented in WAMIT. In many cases of practical importance, it is now possible to represent the geometry exactly to avoid the extra work required previously to develop panel input files for each structure. It is also possible to combine the same or different structures which are represented in this manner, to analyze multiple-body hydrodynamic interactions. Also described is the pre-corrected Fast Fourier Transform method (pFFT) which can reduce the computational time and required memory of the low-order method by an order of magnitude. In addition to descriptions of the two methods, several different applications are presented.

The grain boundary structure and its energy are necessary for the fundamental understanding of the physical properties of materials. In aluminum, three distinct atomic structures of a Σ9(221)[110] tilt grain boundary have been reported in previous studies using atomistic simulations and a high-resolution transmission electron microscopy (HRTEM). In this work, we studied the atomic structure and energy of the Σ9 tilt grain boundary in aluminum using first-principles calculations. A comparison of the grain boundary energies among the three distinct Σ9 tilt grain boundaries determined through first-principles calculations allowed us to identify the most stable atomic structure of Σ9 tilt grain boundary in aluminum.

Abstract:
The structure and thermodynamic properties of a Σ5 (001) twist boundary in gold are studied as a function of temperature. This study was performed within the framework of the Local Harmonic (LH) model and employed an Embedded Atom Method (EAM) potential for gold. We find that for the Σ5 (001) twist boundary in gold, a distorted CSL structure is stable at low temperatures, but undergoes a phase transformation to a DSC related structure near room temperature. This transformation is shown to be first order. The temperature dependences of the excess grain boundary free energy, enthalpy, entropy, specific heat, and excess volume are calculated. Discontinuities are observed in the slope of the grain boundary excess free energy (versus temperature), in the value of the grain boundary excess specific heat and excess volume. The stable high temperature grain boundary structure has a smaller excess volume than does the lower temperature structure, and both structures have a coefficient of thermal expansion which is in excess of that for the perfect crystal.

Abstract:
Turbulent Rayleigh–Bénard convection with a mixed isothermal–adiabatic bottom boundary is simulated to investigate the effect of a nonideal thermal boundary on vortex structure and small-scale characteristics in turbulent convection. Simulations of convection with element aspect ratios of the mixed isothermal–adiabatic boundary cell ranging from [Formula: see text] to [Formula: see text] are performed at fixed Rayleigh and Prandtl numbers. Within the parameters adopted in this paper, the large-scale circulation under the mixed boundary condition is found to be consistent with that under the classical isothermal condition. However, the shape characteristics and distribution of plumes are strongly affected by the presence of a mixed isothermal–adiabatic boundary. Compared with the isothermal system, the mixed boundary breaks up the corner vortex structures and reduces the vortex intensity at the corners. Some complex vortex structures, such as a horseshoe vortex, appear in the case of a mixed isothermal–adiabatic thermal boundary. The vortices in side and face regions are governed by an enhancement rule that is related to the ratio of the element width to the typical plume size. The structure functions of scales above the element scale are greatly affected by the presence of a mixed boundary. The temperature structure function exhibits discrete characteristics, especially in the near-bottom region. However, the velocity structure function of the velocity retains continuous characteristics in all regions. The small-scale characteristics observed here help provide better understanding of the effect of a discrete boundary on buoyancy-driven turbulent convection.

The two-mode phase field-crystal (PFC) method is used to simulate the nanograin growth, including the grain growth in different sets of crystal planes, the grain boundary structure with mismatch, the grain orientation and also the incoherent grain boundary in two dimensional plane. It is obviously observed that there are dislocation structures in nanograin boundary due to mismatch and misorientation of grains. These simulation results can not only be used in artificial controlling the grain boundary of nanograin, but also is of significant for designing new nanograin with a good grain boundary for structure materials.

Abstract:
Si le traducteur qui traduit de l'anglais en allemand, respecte les délimitations de la phrase anglaise, la phrase qu'il obtiendra en allemand sera souvent ressentie comme étant trop longue ou trop courte. Ce résultat est dû aux différences que la structure de l'information présente en anglais et en allemand. De nombreuses traductions prouvent que lorsque l'élément le plus important de la phrase — la FOCALE — se trouve en position neutre, il est juxtaposé ä l'élément principal du syntagme verbal. Si l'on fonde la comparaison de l'anglais et de l'allemand sur le paramètre grammatical de base qu'est la latéralité, l'anglais étant une langue de latéralité gauche et l'allemand de latéralité droite, on peut affirmer que la focale se situe ä mi-chemin de la phrase en anglais et en bout de phrase en allemand. Une langue de latéralité gauche tolère la 'longueur', c'est-ä-dire que les structures moins importantes, même lorsqu'elles se présentent sous la forme de propositions, se trouveront en fin de phrase et non pas en début. En revanche, dans les langues de latéralité droite, ces structures apparaîtront au début de la phrase et non ä la fin. C'est précisément en raison de cette différence de latéralité que les traductions qui conservent la structure de l'information du texte d'origine, risquent d'être ressenties comme trop longues ou trop courtes. Parmi les différentes techniques de traduction qui permettent au traducteur de s'exprimer correctement dans la langue d'arrivée, figure le décalage, vers la droite ou vers la gauche, des délimitations de la phrase originale. Pour ce faire, le traducteur pourra soit séparer des propositions ou, inversement, unir des phrases.

Abstract:
Geogrid-reinforced structures are extensively adopted in various engineering fields. At present, the influence of boundary conditions was not considered in design methods, bringing hidden dangers to the safety of the structure. In the current study, a series of pullout tests were carried out on high-density polyethylene (HDPE) geogrid-reinforced coarse sand. The magnitude and growth pattern of pullout resistance and the variation laws of interfacial shear strength indexes under four types of boundary conditions were analyzed. Additionally, the boundary reduction coefficient (BRC) was introduced to establish the relationship between rigid and flexible boundary for the design of the structure. The tests results showed that the boundary conditions cannot be ignored in the design of structures, especially in the front. When the normal loading was up to 120 kPa, the BRC-top and BRC-positive could be taken as 0.9 and 0.5, respectively, and verified by fitting results. The boundary conditions affected the pullout resistance, while the vertical loading corresponding to the maximum pullout resistance was not related to boundary conditions. Investigating the interaction of the geogrid–soil under different boundary conditions can help to improve the understanding of the behavior of reinforced soil structure, and to achieve a more efficient and economical design.

Abstract:
A nonlinear thermal vibration characteristic of the laminate composite thin shell structures under linear temperature field is investigated by finite element method (FEM). The natural frequencies of the composite laminated thin shell structures with different boundary conditions and stacking sequence are calculated and analyzed. Numerical results show that the natural frequencies of the structure are affected by the temperature, boundary conditions and the stacking sequence; the proper stacking angle can change the natural frequencies; the effect degree on the natural frequencies of symmetric composite structures is different from that of the antisymmetric one. These conclusions can provide some guidance to structure design and heat-resistant design of composite structures.
