Abstract:
Purpose – The purpose of this paper is to extract appropriate terms to summarize the current results in terms of the contents of textual facets. Faceted search on XML data helps users find necessary information from XML data by giving attribute–content pairs (called facet-value pair) about the current search results. However, if most of the contents of a facet have longer texts in average (such facets are called textual facets), it is not easy to overview the current results. Design/methodology/approach – The proposed approach is based upon subsumption relationships of terms among the contents

Abstract:
Faceted search is an efficient search method to use the big data and one of its key issues is to extract facets from unstructured webpages automatically. It is still a problem to extract facets from massive unstructured webpages exactly and automatically. To solve the problem, this paper first proposed a novel index structure of webpages, the Multidimensional Semantic Index (MDSI), which holds rich semantics and are helpful to extract facets. In MDSI, the differently dimensional semantic indexes are bridged by mining the semantic mapping between them. Then, an automatic facet extraction method

Abstract:
The generation of boundaries from the triangular meshes of CAD object is very important for successful surface segmentation and subdivision. Considering the characteristics of non-uniformity, sparseness and known facet normal for STL model, which is generated by a CAD system, a new and efficient approach for extracting boundaries on STL model is presented in this paper. Boundaries are classified into sharp feature edge and non-sharp feature edge embedded in the filleting and transitive region. The former is detected based on dihedral edge angle (angle between facets), while the latter is ident

Abstract:
In this paper, we propose an obstacle detection approach that uses a facet-based obstacle representation. The approach has three main steps: ground point detection, clustering of obstacle points, and facet extraction. Measurements from a 64-layer LiDAR are used as input. First, ground points are detected and eliminated in order to select obstacle points and create object instances. To determine the objects, obstacle points are grouped using a channel-based clustering approach. For each object instance, its contour is extracted and, using an RANSAC-based approach, the obstacle facets are select

Abstract:
Boundary extraction is a collective term that we use for the process of extracting the locations of faults, lineaments, and lateral boundaries between geologic units using geophysical observations, such as measurements of the magnetic field. The process typically begins with a preprocessing stage, where the data are transformed to enhance the visual clarity of pertinent features and hence improve the interpretability of the data. The majority of the existing methods are based on raster grid enhancement techniques, and the boundaries are extracted as a series of points or line segments. In cont

The facet-specific interaction between molecules and crystalline catalysts, such as titanium dioxides (TiO2), has attracted much attention due to possible facet-dependent reactivity. Using surface-sensitive sum-frequency vibrational spectroscopy, we have studied how methanol interacts with different common facets of crystalline TiO2, including rutile(110), (001), (100), and anatase(101), under ambient temperature and pressure. We found that methanol adsorbs predominantly in the molecular form on all of the four surfaces, while spontaneous dissociation into methoxy occurs preferentially when th

Active contours are now a very popular technique for shape extraction, achieved by minimising a suitably formulated energy functional. Conventional active contour formulations suffer difficulty in appropriate choice of an initial contour and values of parameters. Recent approaches have aimed to resolve these problems, but can compromise other performance aspects. To relieve the problem in initialisation, an evolutionary dual active contour has been developed, which is combined with a local shape model to improve the parameterisation.

Visual surveillance finds increasing deployment for monitoring urban environments. Operators need to be able to determine identity from surveillance images and often use face recognition for this purpose. Unfortunately, the quality of the recorded imagery can be insufficient for this task. This study describes a programme of research aimed to ameliorate this limitation. Many face biometrics systems use controlled environments where subjects are viewed directly facing the camera.

Hence, the adoption of digital technologies appears as a unique opportunity that would enable the industry to meet the cha

Abstract:
As the global shift towards a low-carbon economy accelerates, demand for critical minerals is projected to soar, intensifying pressures on supply chains and local environments. Policies like the European Union’s Critical Raw Materials Act and the U.S. Inflation Reduction Act are increasingly proposed to secure mineral access while upholding environmental standards and reducing ecological impacts. However, mining activities face significant civil resistance worldwide. This paper reveals that opposition to mineral extraction is a pervasive global phenomenon, spanning diverse sociopolitical conte

Abstract:
Ecuador's economic performance has lagged behind its potential and the broader Latin American region since 2010. Despite rising public debt and financial support from international institutions, Ecuador's economic growth remains stagnant. This paper seeks to characterize the key structural factors impeding Ecuador's economic growth and identify policies that could enhance it. We develop an analytical model framed within the Melitz (2003) framework to examine the implications of a state-controlled monopoly over extractive export-driven industries and the redistributive mechanisms that sustain l

Abstract:
Recent advancements of electric vertical take-off and landing (eVTOL) aircraft have generated significant interest within and beyond the traditional aviation industry, and many novel applications have been identified and are in development. One promising application for these innovative systems is in firefighting, with eVTOL aircraft complementing current firefighting capabilities to help save lives and reduce fire-induced damages. With increased global occurrences and scales of wildfires—not to mention the issues firefighters face during urban and rural firefighting operations daily—eVTOL tec

Abstract:
The Windsor quadrangle, situated in the northern part of the Colorado Piedmont, features relatively low topographic relief with a 94-meter variance between its highest and lowest points. Notable elongated outcrop areas of weathered bedrock are observed along the dissected southwest side of the Cache la Poudre River valley. While fresh bedrock is mainly found in lower gravel pit faces in the Big Thompson River valley, unconsolidated Quaternary deposits cover most of the quadrangle with few natural exposures along river cut banks. The landscape is primarily characterized by a broad upland swath

Abstract:
The Latin American and Caribbean region offers a rich history of innovative policies and investments in urban mobility. We review some of these experiences with the aim of extracting lessons that can provide guidance to policymakers in the design and implementation of successful urban transport reforms. Special emphasis is placed on users' welfare and how different policies impinge on their interests and behavior. Many reforms have faced difficulties by not considering the consequences of policy initiatives on users' welfare, especially their impact on time costs. Another relevant theme discus

Abstract:
Canada has the potential for good long-term development of its mineral resources, and needs to maintain a competitive position for crude minerals in export markets. Therefore, Canada should strongly support the mineral exploration and mining sectors. This conclusion is reinforced by the finding that most of the other countries in this study, which represent much of the world's mining technology and mining education expertise, are in or are approaching the decline phase of their mining industries' life cycles. They are also dependent on imported crude minerals, and are turning their R&D
