The Etropy problem has been widely applied in the assessment and analysis of landscape ecology. Research results are just at the indicators, not able to describe the spatial distribution of the landscape. In this paper, we will simulate the results of the application Etropy problem in landscape assessment based on a GIS. A GIS is used to store the information of layers on landscape structure, indicator analysis and map-layer assessment. This is a new research direction, research results of Etropy problem will be simulated by the evaluation map. Research have been applied in Sa Pa area - one of Vietnam's most mountainous district. Research results shown the landscape diversity in the research area and landscape area identification to be conserved.

In variant design, the proliferation of bills of materials makes it difficult for designers to find previous designs that would aid in completing a new design task. This research presents a novel, data mining approach to forming generic bills of materials (GBOMs), entities that represent the different variants in a product family and facilitate the search for similar designs and configuration of new variants. The technical difficulties include: (i) developing families or categories for products, assemblies, and component parts; (ii) generalizing purchased parts and quantifying their similarity; (iii) performing tree union; and (iv) establishing design constraints. These challenges are met through data mining methods such as text and tree mining, a new tree union procedure, and embodying the GBOM and design constraints in constrained XML. The paper concludes with a case study, using data from a manufacturer of nurse call devices, and identifies a new research direction for data mining motivated by the domains of engineering design and information.

Recently, ecosystem services assessment has been developed as an effective tool to exchange and understand science, develop policies, especially in cultural ecosystem services. However, quantification and mapping of cultural ecosystem services are obstructed by complications in their definitions and suitable indicators. It can be solved based on a geomorphological approach. The similarities of related indicators between geomorphological resources and cultural ecosystem services can be a helpful key for quantifying a recreation and tourism, landscape aesthetics and cultural identity in a particular region. Therefore, study applied an Analytical Hiearchy Process (AHP) to cultural ecosystem services assessment in Sapa, Lao Cai province. Six indicators relating to geomorphology, ecology and social were used in the process. Results indicated a high potential of cultural ecosystem services supply in research area, especially in forest, water bodies and paddy fields. Two local regions, that have not brought into play their available geomorphological potential, need to be invested for cultural ecosystem services.

Inverse Distance

Gravity modelling is a necessary process of applying gravity data to practice, and a vital research area in resource exploring and geodesy. Inverse distance weighted (IDW) interpolation is a widely used algorithm in gravity modelling and many other griding procedures. Based on the gravity anomaly data acquired from the airborne gravimetry over a region in the Northwest of China, IDW method is analysed and implemented with varying calculation radius in gravity modelling. The results show that over the study area, with a proper calculation radius, the IDW can give a more precise prediction than quadric surfaces fitting (QSF) method. The distances between sampled points and unsampled points are the only information taken into consideration in the IDW interpolation, so the analysis of the influence by changing the calculation radius of the unsampled points in this test provides a new research direction of error eliminating when using IDW.

This article discusses how to better unlock the information potential of unremarkable, though complex, prehistoric stone-built structures, by integrating the past 30 years worth of Nordic archaeological research results into aspects of the Norwegian Cultural Heritage Management processes. Traditionally, it has been rather commonplace to interpret such manmade collections of rocks as remains of either clearance of fields for agricultural purposes or as containers for burials, but this dichotomy should now be regarded as an oversimplification. The site of Orstad in the county of Rogaland, SW Norway, excavated in 2014, serves as a case study. This paper demonstrates how difficult it can be to put updated theories and methods into proper use in the field. Since these new research results call for changes in the approach to the subject were not sufficiently considered in the planning process, neither time nor budget allowed for an adequate examination of the individual structures and their context. This is likely to cause information loss, which creates challenges for both the excavation and post-excavation phases of an archaeological investigation. This paper stresses the need to update and improve how excavations of such sites are handled within Norwegian cultural heritage management. By applying new approaches, such localities can yield more information about the past than previously assumed.

This article argues that despite a citation review is a rarely used research tool, this can be very useful to assess the impact of new research topics, both from the future research direction and the bibliometric perspectives. An explorative study is presented around the research area marked as Industry 4.0 with the conference paper mentioned in the title of this citation review. Even though the given reference paper is relatively recent, there are already twenty-seven citations listed among three different scholar databases. These are Google Scholar, ResearchGate and Semantic Scholar. In light of this, the article provides a bibliometric confirmation and analysis for the progression of the line of research adopted by de Giorgio et al. in the exploration of non-traditional methods using virtual reality technology and human-robot collaboration for adaptive applications in Industry 4.0. Furthermore, it represents a model for the authors’ self-development and an example of an unconventional approach to scientific work that may help improve related bibliometric research and scholar database strategies to index new articles and topics in the future.

Purpose Exploitation of project opportunities may bring more benefits than stipulated in the initial business case, and even stakeholder benefits that nobody thought of at the project initiation. The purpose of this paper is to suggest a new research area for megaprojects, i.e. the phenomenon of project opportunity exploitation as a means to increase the project benefits. Design/methodology/approach This is a single case study of an infrastructure megaproject, i.e. the construction and operation of a 50+ years old American bridge. Data cover information regarding 60+ years old historical documents, newspaper articles, interviews and video-recordings. Findings The findings of this paper are as follows: exploiting all opportunities created by the project and increasing project benefits require involvement from many categories of stakeholders; stakeholders get more involved in exploiting the opportunities created by the project when they are proud of the project; for some of the project-related opportunities, it might take a long time before they can be exploited (and related benefits achieved); and celebrating achievements of the project stimulate stakeholders to exploit opportunities created by the project and contribute to further project benefits. Research limitations/implications Only few interviews were conducted. Interviewees were biased as all were very proud of the bridge. This is a single case study of a “rare species”, not representing most megaprojects. Practical implications To enhance project opportunity exploitation and increased benefits, the project owner (team) must continuously communicate about the project, also after project execution. Originality/value This study contributes to a gap within the literature on the phenomenon “project opportunity exploitation”. This is a very rich case study and of a “rare species”.

The Waves

Hong Kong’s autonomy within China is akin to a house built on sand. This article examines how Hong Kong’s autonomy has weathered the waves over the years by adopting a news events analysis approach, documenting the Hong Kong government and the CCP-state’s divergence from the autonomy, democratization, and human rights provisions of the Sino-British Joint Declaration and the Basic Law since 1997. The case study of Hong Kong indicates the profound challenge of practicing territorial autonomy within a communist state and points to a new research direction for conducting comparative autonomies studies across communist and post-communist states.

AbstractResearchers in answer set programming and constraint programming have spent significant efforts in the development of hybrid languages and solving algorithms combining the strengths of these traditionally separate fields. These efforts resulted in a new research area: constraint answer set programming. Constraint answer set programming languages and systems proved to be successful at providing declarative, yet efficient solutions to problems involving hybrid reasoning tasks. One of the main contributions of this paper is the first comprehensive account of the constraint answer set language and solver ezcsp, a mainstream representative of this research area that has been used in various successful applications. We also develop an extension of the transition systems proposed by Nieuwenhuis et al. in 2006 to capture Boolean satisfiability solvers. We use this extension to describe the ezcsp algorithm and prove formal claims about it. The design and algorithmic details behind ezcsp clearly demonstrate that the development of the hybrid systems of this kind is challenging. Many questions arise when one faces various design choices in an attempt to maximize system's benefits. One of the key decisions that a developer of a hybrid solver makes is settling on a particular integration schema within its implementation. Thus, another important contribution of this paper is a thorough case study based on ezcsp, focused on the various integration schemas that it provides.

Resilient socioeconomic unsustainability poses a threat to democracy whose importance has yet to be fully acknowledged. As the prospect of sustainability transition wanes, so does perceived legitimacy of institutions. This further limits representative institutions’ ability to take action, making democratic deepening all the more urgent. I investigate this argument through an illustrative case study, the 2017 People’s Climate March. In a context of resilient unsustainability, protesters have little expectation that institutions might address the ecological crisis and this view is likely to spread. New ways of thinking about this problem and a new research agenda are needed.
