Purpose This paper aims to additive manufacture (AM) the multi-material (MM) structure with directional-specific mechanical properties based on the classical lamination theory of composite materials. Design/methodology/approach The polyjet three-dimensional printing (3DP) process is used to fabricate the MM structure with directional-specific mechanical properties. MMs within a layer are positioned and oriented based on the classical lamination theory to achieve directional-specific properties. Mechanical behavior of the AM structure was examined under various loading conditions to justify the

Shape memory alloy (SMA) is a type of smart material with huge driving force, and large driven displacement. Using SMA as the structure driver may force a bi-directional deformation structure that can achieve high efficiency and compact driving structure. SMA, together with elastic component, forms the two-way driving structure; however the two, if respectively serving as the driver, can enable the occurrence of the simplest bi-directional drivable structure. The offset structure constituted by SMA, not only can achieve two-way drive, and does not require continuous input of energy during the

Acoustic skyrmion modes are topological texture structures of velocity field vectors generated on the surface of acoustic structures. This protected vector distribution provides new dimensions for advanced sound information processing, transmission, and data storage. In this study, we design a combined structure of waveguides and spiral structures, using directional acoustic sources to excite waveguide mode transmission, thereby achieving selective excitation of localized acoustic skyrmion modes. Through theoretical analysis and numerical simulations, we studied the pressure field distribution

Abstract:
Seismic coherence is widely used in seismic interpretation and reservoir characterization to highlight (with low values) faults and stratigraphic features from a seismic image. A coherence image can be computed from the eigenvalues of conventional structure tenors, which are outer products of gradients of a seismic image. I have developed a simple but effective method to improve such a coherence image by using directional structure tensors, which are different from the conventional structure tensors in only two aspects. First, instead of using image gradients with vertical and horizontal deriv

Abstract:
The principal goal of this paper is to show that spatial PPs in English and Dutch have a layered internal structure. In these languages, we find PP constructions containing multiple Ps, which can be analyzed as having a layered PP structure. That is, [+locational] PP headed by lexical P is embedded in [±directional] pP headed by functional p. Following van Riemsdijk (1990) and Emonds (2001), I further propose that in English, both [+locational] P and [±directional] p are head-initial, while in Dutch, the former is head-initial and the latter, head-final.

Additionally, to obtain the multi-directional effect of the cloaking structure, an optimized slice is mirror symmetrized through a radial perimeter.

The dynamic interaction between the soil and the structure resting on it during earthquakes can alter the response characteristics both of the structure and the soil. Despite significant efforts over the past decades, the interaction effect is not yet fully understood and is sometimes misunderstood.

Range finding is performed by a structure-from-motion method, which recovers the three-dimensional position of objects in the environment from omni-directional images. This leads to map-making, which is accomplished using certainty grids to fuse information from multiple readings into a two-dimensional world model.

The principal goals of this thesis are (i) to investigate how the syntax of such nature derives PPs in accordance with the properties of Ps and (ii) to show how the internal PP structure interacts with the external syntax of PP. Chomsky's minimalist framework assumes two syntactic operations, i.e.. Merge and Move, and two different types of outcome of the operations

Of the 20 standard amino acids, cysteines are the only amino acids that have a reactive sulphur atom, thus enabling two cysteines to form strong covalent bonds known as disulfide bonds. Even though almost all proteins have cysteines, not all of them have disulfide bonds. Disulfide bonds provide structural stability to proteins and hence are an important constraint in determining the structure of a protein. As a result, disulfide bonds are used to study various protein properties, one of them being protein folding. Protein structure prediction is the problem of predicting the three-dimensiona

Abstract:
Is the perineuronal net structure within emotional processing brain regions associated with changes in affective state? The objective of this scoping review is to bring together the literature on human and animal studies which have measured perineuronal net structure in brain regions associated with emotional processing (such as but not limited to amygdala, hippocampus and prefrontal cortex). Perineuronal nets are a specialised form of condensed extracellular matrix that enwrap and protect neurons (Suttkus et al., 2016), regulate synaptic plasticity (Celio and Blumcke, 1994) and ion homeostasi

Abstract:
This research is grounded in the theory that scale-free networks form between many organizations in a community when coordinating social care services and influential hubs in the network emerge (Barabási &amp; Réka, 1999).We explore the variability in the structures of social care networks, focusing on how the diverse needs of community members and the array of providers influence these structures. We posit that the architecture of these networks may hold the key to discerning patterns in community health and social outcomes. Our study examines the resilience of social care networks, defining

Abstract:
Drilling fluid plays a key role in the installation of a pipeline by horizontal directional drilling (HDD) and accounts for the majority of the associated environmental impact. An improper drilling fluid program can result in stuck pipe. Uncontrolled discharge of drilling fluid downhole can damage or undermine adjacent structures.The cost of drilling fluid involved with pipeline installation, particularly when disposal costs are considered, can be substantial. This manual is the principal product of PRC project PR-227-9321. Its purpose is to increase the level of technical sophistication relat
