Human-Robot Collaborations in Industrial Automation

Technology is changing the manufacturing world. For example, sensors are being used to track inventories from the manufacturing floor up to a retail shelf or a customer’s door. These types of interconnected systems have been called the fourth industrial revolution, also known as Industry 4.0, and are projected to lower manufacturing costs. As industry moves toward these integrated technologies and lower costs, engineers will need to connect these systems via the Internet of Things (IoT). These engineers will also need to design how these connected systems interact with humans. The focus of this Special Issue is the smart sensors used in these human–robot collaborations

Innovative Methods and Materials in Structural Health Monitoring of Civil Infrastructures

In the past, when elements in sructures were composed of perishable materials, such as wood, the maintenance of houses, bridges, etc., was considered of vital importance for their safe use and to preserve their efficiency. With the advent of materials such as reinforced concrete and steel, given their relatively long useful life, periodic and constant maintenance has often been considered a secondary concern. When it was realized that even for structures fabricated with these materials that the useful life has an end and that it was being approached, planning maintenance became an important and non-negligible aspect. Thus, the concept of structural health monitoring (SHM) was introduced, designed, and implemented as a multidisciplinary method. Computational mechanics, static and dynamic analysis of structures, electronics, sensors, and, recently, the Internet of Things (IoT) and artificial intelligence (AI) are required, but it is also important to consider new materials, especially those with intrinsic self-diagnosis characteristics, and to use measurement and survey methods typical of modern geomatics, such as satellite surveys and highly sophisticated laser tools

Urban Deformation Monitoring using Persistent Scatterer Interferometry and SAR tomography

This book focuses on remote sensing for urban deformation monitoring. In particular, it highlights how deformation monitoring in urban areas can be carried out using Persistent Scatterer Interferometry (PSI) and Synthetic Aperture Radar (SAR) Tomography (TomoSAR). Several contributions show the capabilities of Interferometric SAR (InSAR) and PSI techniques for urban deformation monitoring. Some of them show the advantages of TomoSAR in un-mixing multiple scatterers for urban mapping and monitoring. This book is dedicated to the technical and scientific community interested in urban applications. It is useful for choosing the appropriate technique and gaining an assessment of the expected performance. The book will also be useful to researchers, as it provides information on the state-of-the-art and new trends in this fiel

A risk management model for commercial property development and investment in Ghana

Commercial property development and investment provide many benefits to individuals and governments around the globe; these include the generation of income for investors, employment, tax revenues, and contributions to a country‘s GDP. Yet commercial property development and investment projects involve construction, economic and management risks. A lack of effective risk assessment and management tools may lead to developers and investors incurring losses. To curtail such losses, this study sought to create a credible management model that can be used to assess and manage risks in Ghana‘s commercial property development and investment industry. An extensive literature review was done, covering all 12 identified study constructs: real estate trends and cycle, construction project management, outside advice/mentorship, spatial development, strategic factors, business management skills, PMBOK, PESTEL analysis, general management skills, governance structures, financial feasibility, professional feasibility, and risk management. Each construct was defined and operationalised. A positivistic philosophical approach was used, and quantitative approach was used to solicit data from the main respondents through the distribution of questionnaires to the target population sample. CB-SEM and SPSS version 24 were used to analyse data, SEM to test the positive relationships hypothesised between the identified variables and SPSS to analyse the demographic data. The major findings are that there is a lack of financial and professional feasibility analysis among respondents along the following factors: the PMBOK, real estate trends and cycles, general management, business management, strategic factors, spatial development, and PESTEL analysis. It was found that these factors have positive and favourable influences on CPDI projects. The study recommends that developers and investors do financial and professional feasibility studies before they embark on projects. This could improve project viability in commercial property development and investment. The study has contributed to the body of knowledge in CPDI sector by developing a new risk assessment/risk management model.Thesis (PhD) -- Faculty of Engineering Built Environment and Technology, School of the built Environment, 202

Regenerative Circularity for the Built Environment – A Positive Impact Framework for Urban Transitions

The detrimental impacts of human activities on social and ecological systems are increasingly evident, with cities and their inefficient built environment (BE) stock being significant contributors. Neighbourhood sustainability assessment tools (NSATs) have been developed by the BE sector for new precincts; however, many have limitations and adopt linear approaches unsuitable for complex urban areas. While the circular economy (CE) model has gained global attention, its integration into NSATs remains limited. This thesis adopts a cross-pollination perspective, combining the CE model with regenerative design concepts. Through inductive content analysis, the 'Regenerative Circularity for the Built Environment' (RC4BE) conceptual model is proposed. Based on this model, a framework is developed to support the positive impact-based transition of existing urban precincts and neighbourhoods. To explore current green practices, six ecological urban developments across three continents were studied. Surveys and semi-structured interviews with over 150 BE professionals examined their practices and perceptions of regenerative and circular approaches. A 2-round Delphi consultation with 31 international experts validated a set of five themes, 26 categories, and 136 criteria derived from literature and previous stages. This informed the design of a mixed performance-based and maturity model assessment framework with four different evaluation components. The findings suggest shortcomings in existing NSATs and green precincts, while experts express a desire to improve their practises. The resulting RC4BE framework provides a flexible, systemic approach that is adaptable to different contexts while also empowering various urban players. It serves as a platform for citizen-led community improvements towards positive impacts. This thesis contributes to the development of sustainable cities by presenting a unique framework that incorporates circular and regenerative design concepts. It goes beyond traditional approaches to sustainability by emphasising neighbourhood-scale transformations and recognising the critical role of local communities. Along with environmental and economic issues, social factors as community participation and equity are considered. The framework's holistic, process-based approach recognises the interdependence of urban systems. By involving BE practitioners and stakeholders, a more inclusive, realistic implementation is ensured, boosting real-world relevance and impact

The International Linear Collider Technical Design Report - Volume 4: Detectors

The International Linear Collider Technical Design Report (TDR) describes in four volumes the physics case and the design of a 500 GeV centre-of-mass energy linear electron-positron collider based on superconducting radio-frequency technology using Niobium cavities as the accelerating structures. The accelerator can be extended to 1 TeV and also run as a Higgs factory at around 250 GeV and on the Z0 pole. A comprehensive value estimate of the accelerator is give, together with associated uncertainties. It is shown that no significant technical issues remain to be solved. Once a site is selected and the necessary site-dependent engineering is carried out, construction can begin immediately. The TDR also gives baseline documentation for two high-performance detectors that can share the ILC luminosity by being moved into and out of the beam line in a "push-pull" configuration. These detectors, ILD and SiD, are described in detail. They form the basis for a world-class experimental programme that promises to increase significantly our understanding of the fundamental processes that govern the evolution of the Universe.Comment: See also http://www.linearcollider.org/ILC/TDR .
