One of the largest recreational waterfront projects ever designed (Sasaki Associates, 1979) is located along 20 kilometers (km) of the City of Kuwait on the Arabian Gulf (Fig. 1). Planning and design were initiated in 1976, and the first phases of construction were completed in 1985. Amenities included artificial beaches, promenades, waterfront parks, and an artificial island. Extensive armoring has also been installed, ranging from 10-ton, dolosse breakwaters to large, quarry-stone revetments. Total investment in the first two phases is upwards of US $100 million.

The uniqueness and inherent complexities of the construction industry require the use of Artificial Intelligence (AI) to improve its processes and enhance overall competitiveness and performance. This study examined the awareness level and application of AI to provide useful insights into the state of AI applications in the Nigerian construction industry. A quantitative research design with the use of a questionnaire was used to obtain data from 53 construction professionals in the Lagos Island area of Lagos State, Nigeria. The professionals included Quantity Surveyors, Architects, Civil Engineers, Builders, and Estate Surveyors selected based on a purposive sampling technique. Data from the survey were analyzed with frequencies, mean, and ANOVA. The study found that most of the respondents were aware of the application of AI in construction, and there was no difference in the awareness level of the participants irrespective of their professional affiliations, organizational type, and organizational size. Generally, the most common application of AI among the participants surveyed were generative designs in BIM, measurement and estimating software, and the use of sensors in intelligent buildings. Moreover, design and project planning was found to be the most critical areas of need for AI in the study area. The study underscores the need for investments in other AI applications other than BIM and estimating software to improve productivity, performance, and enhance client satisfaction.

Groundwater is a critical resource in remote and isolated islands where rainfall hardly provides a continuous and even water supply. In this paper, in a very rare and uncommonly found artificial aquifer on Miyako Island, far away from the main continent of Japan, with limited experimental results of evaluations of crop water requirement, MODIS ET together with crop ETc estimated from Kc coefficient from the nearest island were compared to determine the reliability of the MODIS ET and FAO-56-based ETc value. The testified Kc approach for sugarcane ET was used to assess the risk of irrigation water shortages using historical metrological data and to predict the future risk of irrigation agriculture under different scenarios of GCM models. It was shown that FAO-56-based ETc and MOD16A2 were both applicable for crop evapotranspiration on the island. Then, the response of groundwater storage to gross irrigation water requirement was analyzed to clarify the effect of irrigation on groundwater storage and the risk of groundwater depletion under current and future climatic conditions. Results showed that the construction of the dam efficiently secured the irrigation of sugarcane. Using historical climatic data (1951–2021), the influence of estimated irrigation water requirements on groundwater showed that in 296 out of 852 months, irrigation was heavily required. Over a 71 year period, there was absolutely no water for irrigation four times, or nearly once every 18 years. Under the future projected climate from four bias-corrected GCM models with two emission scenarios (2022–2100), the risk of groundwater depletion both in terms of frequency and duration will increase. Therefore, there is a need for either improvement of irrigation water management or additional construction of artificial aquifers on the island. The study proved the value of ET derived from remote sensing in areas lacking the support of experimental results. The methodology developed in the study can be potentially used to evaluate long-term irrigation demand and groundwater management over dry periods for engineering design or dam construction globally.

Artificial islands and land reclamation are one of the most important ways to expand urban space in coastal cities. Long-term consolidation of reclaimed material and compaction of marine sediments can cause ground subsidence, which may threaten the buildings and infrastructure on the reclaimed lands. Therefore, it is crucial to monitor the land subsidence and predict the future deformation trend to mitigate the damage and take measures for the land reclamation and any infrastructure. In this paper, a total of 125 SAR images acquired by the C-band Sentinel-1A satellite between June 2017 and September 2021 are collected. The small baseline subsets (SBAS) SAR interferometry (InSAR) method is first conducted to detect the land deformation in Xiamen and Zhangzhou cities of Fujian Province, China, and the distributed scatterers (DS)-InSAR method is used to recover the complete deformation history of some typical areas including Xiamen Airport in Dadeng Island and Shuangyu Island. Then, the sequential estimation and the geotechnical model are jointly applied to demonstrate the current and future evolution of land subsidence of the constructed roads on Shuangyu Island. The results show that the maximum cumulative deformation reaches 425 mm of Xiamen Xiang’an Airport and 626 mm of Shuangyu Island, and the maximum deformation is predicted to be as large as 1.1 m by 2026 of Shuangyu Island. This research will provide important guidelines for the design and construction of Xiamen Xiang’an Airport and Shuangyu Island to prevent and control land subsidence.

Three kinds of frozen soils were tested for artificial ground freezing (AGF) project in the tunnel construction of Stonecutters Island Sewage Treatment Works, Hong Kong. Triaxial shear test was conducted to obtain shear strength of frozen soils. From the test, Mohr circles and their envelopes were obtained. According to Mohr circles, shear strength of the three soils was gained. Comparing the three soils, we found the potential weaken layer which might cause failure in the construction. All the parameters obtained can be used in design and construction of AGF practice.

Urbanization has increased the burden on land resources. Artificial island construction has been proven as an effective method for addressing these land resource problems; however, few studies have been conducted on the safety of sea reclamation construction. This paper proposes a systemic approach to the complete safety management process in sea reclamation engineering, including safety system design, analysis, control, and assessment, using the Sanya Sea Reclamation Airport, Hainan Province, China, as a case study. A total of 145 steel cylinders must be vibrated and sunk into the seafloor to create a 9 km quay wall. Owing to their large size, the steel cylinders have been divided into different segments, and an assembly jig is employed to ensure a safe production process. Considering the hazardous working environment in sea reclamation construction, a numerical analysis is conducted to investigate the safe repertory of these steel cylinders and verify the reliability of the selected scheme for their transportation. Finally, control measures are adopted to ensure a safe vibration and sinking procedure for the steel cylinders. The proposed approach could be used to provide safety management guidelines for artificial island engineering and construction.

The United Arab Emirate’s rapid population growth is coupled with an increase in the consumption of natural resources such as fresh air, sunlight, land, and water. In the past two decades, the demand for land has augmented both away from the coast and significantly near the coast. Within coastal zones, artificial reclamation of land in the sea is the most desirable way to meet the demand for land necessary for the development of the most modern urban areas. Seaward reclamation (land in the water) necessitates the construction of artificially reclaimed areas that are extended into the sea using innovative modern construction techniques. The majority of these building requirements are necessitated by a number of key factors and have diverse outcomes. Even though this type of urban expansion is not new, the scale and motivations of land reclamation have been drastically altered due to geological and human-induced factors. The purpose of this paper is to assess the increase in seaward land expansion, particularly in the seven UAE coastal emirates. Using satellite data, particularly from 1990 to 2021, the total increase in land due to newly developed reclaimed areas in all UAE coastal emirates is calculated. Satellite images from the Landsat series are used to analyze the tremendous growth since the early 2000s. In addition, the study of shoreline maps of 1990, 2000, 2010, and 2021 for the seven emirates revealed that the 22 km long Ajman and UAQ front coast experienced a notable shoreline retreat with a net erosion area of 300 m2 and an annual rate of 30 my−1 over the past 21 years (2000–2021). Depending on the type of construction design used to describe the process, a methodical sorting is also recommended. The impacts of the Dubai offshore reclaimed islands on the adjacent coastlines in Ajman and Umm Al Quwain (UAQ), as well as the potential impact of earthquake tremors along the Zagros fold belt region, are the subjects of this study. In this study, all seven coastal emirates are considered, and the largest reclamation projects are located in Dubai, Abu Dhabi, Ras-Al Khaimah (RAK), and Fujairah, with Dubai leading the way; it has expanded its coastal areas by more than 68 km2 at present, and another 35 km2 will be reclaimed soon to finish Palm Deira.

Abstract Roof greening can make up for the problem of urban green deficiency to some extent, add green space for people in urban life, and also alleviate urban ecological problems and heat island effect. With the development of information technology, the development level of modern automation is higher and higher. Information has penetrated into various industries. So it is very important to develop intelligent management system(IMS) of roof greening to use information technology reasonably. At present, roof greening is mainly artificial operation management, and there are many random factors and can not guarantee that roof greening is always the best state. Irrigation system is also very simple. Therefore, this paper proposes the research and construction of IMS of Roof Greening Based on wireless sensor network(WSN) technology. This paper describes the frame design of IMS of roof greening and the overall design of IMS of roof greening. The design factors of WSN are also studied. The plant survival rate of intelligent management and natural growth is studied by field detection. The effect of roof greening on reducing heat island effect is proved by data chart. The experimental results show that the survival rate of plants under the care of intelligent roof greening system is 91.27, while the natural growth survival rate is only 67.32. At the same time, the green roof plays a great role in the heat island effect. When the sun is the strongest at 12:00 noon, the temperature of the green roof is 25 degrees, while the common roof is 32 degrees.

Known as one of the “seven wonders of the modern world”, the Hong Kong-Zhuhai-Macao Bridge connects Hong Kong, Zhuhai, and Macao. The bridge, which lasted 14 years from design to construction, spans the Lingdingyang waters of the South China Sea to the west, connects Macao and Zhuhai artificial islands, and ends at Zhuhai Hongwan. The bridge, which shortens the traffic distance between the three places and allows the economy, culture, and technology of the three places to communicate with each other, opened up a new world. This paper intends to review the process of the construction of the Hong Kong-Zhuhai-Macao Bridge and sort out the expected benefits of the bridge’s opening to traffic. Then, the paper explains the new situation faced by the Hong Kong-Zhuhai-Macao Bridge. Based on the outward service function model of city flow and the interaction strength model, we conduct an empirical study on the economic status of the Guangdong-Hong Kong-Macao Greater Bay Area. This paper analyzes the interaction between the cities which are in the Greater Bay Area and uses panel data to conduct regression analysis to verify the important impact of the Hong Kong-Zhuhai-Macao Bridge on the development of cities in the Pearl River Delta. Finally, conclusions are drawn: Hong Kong-Zhuhai-Macao Bridge is undoubtedly of positive significance to strengthen economic and social ties between the West Bank of the Pearl River and Hong Kong, and Hong Kong has a large economic radiation capacity to the cities that are in the Pearl River Delta and Macao in the construction, finance, transportation, warehousing, and communications industries. And corresponding suggestions are put forward.

White building components, whether decorative or the overall structure, are susceptible to extreme weathering conditions, which affect the durability of the building’s external surface. In particular, white natural stone materials can provide buildings with beauty, durability, and sustainability, but this beauty is affected by key factors determining their weather resistance, namely physical properties such as porosity and acid and alkali resistances. As indicated by a past study, marble used as the exterior wall of a building in a similar environment will exhibit tarnishing after six months of weathering. Taiwan is a subtropical island, so the weather resistance of building materials to this environment is worthy of attention. As pointed out by the study, raw stone materials containing zirconium and silica can have greater weather resistance, do not easily change color, and possess good stress resistance properties. Focusing on this, this study attempted to identify stone materials with such compositions and sent samples to SGS (Societe Generale de Surveillance S.A., New Taipei City, Taiwan) for testing of weather resistance. This paper uses Spanish artificial stones for the study and observes the changes in the surface cleanliness on two buildings in Yilan County and Taipei in Taiwan after exposure to sun and rain. The experiments were conducted over two years. The study results showed that the artificial stones displayed no change in outward appearance under both rainy and acid rain environments. In Yilan, construction of an exterior wall was carried out in February 2018. The exterior wall used the white artificial stone directly from the manufacturer, and the black artificial stone with added paint for stone protection. After two months, the black artificial stone covered with paint exhibited a change in color and stains appeared on the surface, while the white artificial stone not covered with paint maintained the same cleanliness after two years. In Taipei, white Spanish artificial stone was used for the exterior wall of an entire building block in February 2020. After the frame was dismantled in September 2020, the color was found to be unaffected, being as pure white as it was when new. Therefore, this study selected Spanish artificial stone for the design of a building’s exterior wall, as the cleanliness of the stone surface is not affected and it has good applicability in rainy and acid rain island environments.

Human balance and locomotion control is highly complex and not well understood. To understand how the nervous system controls balance and locomotion works, we test how the body responds to controlled perturbations, the results are analyzed, and control models are developed. However, to recreate this system of control there is a need for a robot with human-like kinematics. Unfortunately, such a robotic testbed does not exist despite the numerous applications such a design would have in mobile robotics, healthcare, and prosthetics. This thesis presents a robotic testbed model of human lower legs. By using MRI and CT scans, I designed joints that require lower force for actuation, are more wear resistant, and are less prone to catastrophic failure than a traditional revolute (or pinned) joints. The result of using this process is the design, construction, and performance analysis of a biologically inspired knee joint for use in bipedal robotics. For the knee joint, the design copies the condylar surfaces of the distal end of the femur and utilizes the same crossed four-bar linkage design the human knee uses. The joint includes a changing center of rotation, a screw-home mechanism, and patella; these are characteristics of the knee that are desirable to copy for bipedal robotics. The design was calculated to have an average sliding to rolling ratio of 0.079, a maximum moment arm of 2.7 inches and a range of motion of 151 degrees. This should reduce joint wear and have kinematics similar to the human knee. I also designed and constructed novel, adjustably-damped hip and ankle joints that use braided pneumatic actuators. These joints provide a wide range of motion and exhibit the same change in stiffness that human joints exhibit as flexion increases, increasing stability, adaptability, and controllability. The theoretical behaviors of the joints make them desirable for use in mobile robotics and should provide a lightweight yet mechanically strong connection that is resistant to unexpected perturbations and catastrophic failure. The joints also bridge the gap between completely soft robotics and completely rigid robotics. These joints will give researchers the ability to test different control schemes and will help to determine how human balance is achieved. They will also lead to robots that are lighter and have lower power requirements while increasing the adaptability of the robot. When applying these design principles to joints used for prosthetics, we reduce the discomfort of the wearer and reduce the effort needed to move. Both of which are serious issues for individuals who need to wear a prosthetic device.

El presente trabajo aborda la especificación, diseño e implementación de organizaciones abiertas de agentes. Se defiende que tales organizaciones pueden ser diseñadas e implementadas de manera efectiva como organizaciones electrónicas institucionalizadas (instituciones electrónicas) compuestas de un gran número de agentes heterogéneos (tanto humanos como software) adoptando diversos roles e interactuando por medio de ilocuciones. Adicionalmente postulamos que el diseño y la implementación de instituciones electrónicas deben ser guiadas por una metodología bien fundamentada. Es por ello que proponemos una especificación formal de instituciones electrónicas que fundamente su diseño, análisis e implementación
A continuación presentamos un modelo computacional que emerge de y fielmente captura la formalización resultante de la noción de institución electrónica. Nuestro modelo computacional se define y explota sobre la base de la noción de mediación para fundamentar la construcción de infraestructuras para instituciones electrónicas. Así, proponemos construir instituciones electrónicas a partir de agentes institucionales ---agentes en los que la institución delega sus servicios e interagentes ---agentes software autónomos dedicados a mediar la interacción entre cada agente y la sociedad de agentes en el marco de una institución electrónica. De esta manera las instituciones electrónicas son concebidas computacionalmente como instituciones electrónicas mediadas por agentes, ya que tanto los servicios institucionales como las interacciones son mediados por agentes.
Ilustramos la construcción práctica de instituciones electrónicas mediadas por agentes describiendo el desarrollo de una casa electrónica de subastas inspirada en las lonjas de pescado tradicionales donde agentes heterogéneos (humanos y software) pueden comerciar.
Finalmente presentamos la evolución de la casa de subastas electrónicas a una plataforma para la experimentación en escenarios de subasta. Mostramos cómo en tales escenarios agentes compradores y vendedores de diferentes complejidades participan en subastas definidas de acuerdo a unas condiciones de mercado estandarizadas, siendo evaluados en función de su rendimiento en el mercado. Desde nuestro punto de vista tales escenarios competitivos constituyen interesantes y ricos dominios en los que estudiar cuestiones generales relacionadas con arquitecturas de agentes que comercian y, más específicamente, con sus comportamientos estratégicos.
This thesis focuses on the specification, design and implementation of open agent organisations. We argue that open agent organisations can be effectively designed and implemented as institutionalised electronic organisations (electronic institutions) composed of a vast amount of heterogeneous (human and software) agents playing different roles and interacting by means of speech acts. Then we take the view that the design and development of electronic institutions must be guided by a principled methodology. For this purpose we propose a formal specification of electronic institutions that founds their design, analysis and development.
Next we present a computational model that arises from and fully captures the resulting formalisation of electronic institution. Our computational model strongly relies on and exploits the notion of mediation for founding the realisation of electronic institutions' infrastructures. Thus we propose how to fully realise an electronic institution based on institutional agents ---the agents to which the institution delegates its services--- and interagents ---autonomous software agents devoted to mediating the interaction between each agent and the agent society in the framework of an electronic institution. Therefore electronic institutions are computationally conceived as agent-mediated electronic institutions since both institutional services and interactions are mediated by agents.
We illustrate the practical realisation of agent-mediated electronic institutions by describing the development of an electronic auction house inspired by the age old institution of the fish market where heterogeneous (software and human) agents may trade.
Lastly we present the evolution of the electronic auction house into a test-bed for experimenting with auction-based trading scenarios. We show how in these scenarios trading agents of arbitrary complexity participate in auctions under a collection of standardised market conditions and are evaluated according to their actual market performance. We argue that such competitive situations constitute convenient problem domains in which to study issues related with trading agent architectures in general and agent-based trading strategies in particular.

ENGLISH ABSTRACT: In this thesis the design and testing of the baseband components of a modem intended for use as a telemetry and control link for a low earth orbit satellite is presented. This includes parts of the physical layer as well as a basic data-link layer. Binary phase-shift keying (BPSK) is used as the modulation scheme and is realised by making use of software defined radio on a standard x86 computer with digital to analogue and analogue to digital converters that use a universal serial bus (USB) connection. The data-link layer makes use of a basic framing scheme and provides bit synchronisation, an automatic repeat request (ARQ) system and Bose Chaudhuri Hocquenghem (BCH) forward error correction (FEC). The ARQ system ensures that data is delivered reliably and the FEC improves the system’s performance in noisy conditions. A prototype system was developed to test the performance of the individual layers as well as the system as a whole. For testing purposes the Linux Internet Protocol (IP) stack is used as higher network layers. Radio frequency hardware developed by Verschaeve [1] modulates the signal away from baseband, transmits it over the air and receives it.
AFRIKAANSE OPSOMMING: In hierdie tesis word die ontwerp en toetsing van die basisband komponente van ‘n modem, bedoel vir gebruik op ‘n satelliet in ‘n lae-aarde wentelbaan, bespreek. Die ontwerp sluit dele van die fisiese vlak sowel as ‘n verbindingsvlak in. Binêre faseskuifsleuteling word gebruik as die modulasieskema en word verwesenlik deur gebruik te maak van sagteware gedefinieerde radio. Dit voer uit op ’n standaard x86 rekenaar wat deur middel van USB gekoppel is aan ’n digitaal-na-analoog- en ’n analoog-na-digitaal-omsetter. Die verbindingsvlak het ‘n eenvoudige ramingskema. Dit voorsien bis sinkronisasie, die hersending van verlore rame en Bose Chaudhuri Hocquenghem (BCH) voorwaartse foutverbetering. Die hersending van verlore rame verseker dat data betroubaar oorgedra kan word en foutverbetering verbeter die stelsel se vermoëns in ruiserige toestande. ‘n Prototipe stelsel is ontwikkel om die vermoëns van die individuele vlakke, sowel as die stelsel as ’n geheel, te toets. Tydens toetsing is die Linux Internet Protokol stapel gebruik vir die hoër netwerk vlakke. Radio komponente wat deur Verschaeve [1] ontwikkel was is gebruik om die sein uit te saai en te ontvang.

In this thesis, a new approach combining neural networks and genetic algorithms is presented for microwave design. In this method, an accurate neural network model is developed from the experimental data. This neural network model is used to perform sensitivity analysis and derive response surfaces. An innovative technique is then applied in which genetic algorithms are coupled with the neural network model to assist in synthesis and optimization. The proposed method is used for modeling and analysis of circuit parameters for flip chip interconnects up to 35 GHz, as well as for design of multilayer inductors and capacitors at 1.9 GHz and 2.4 GHz. The method was also used to synthesize mm wave low pass filters in the range of 40-60 GHz. The devices obtained from layout parameters predicted by the neuro-genetic design method yielded electrical response close to the desired value (95% accuracy). The proposed method also implements a weighted priority scheme to account for tradeoffs in microwave design. This scheme was implemented to synthesize bandpass filters for 802.11a and HIPERLAN wireless LAN applications in the range of 5-6 GHz. This research also develops a novel neuro-genetic design centering methodology for yield enhancement and design for manufacturability of microwave devices and circuits. A neural network model is used to calculate yield using Monte Carlo methods. A genetic algorithm is then used for yield optimization. The proposed method has been used for yield enhancement of SiGe heterojunction bipolar transistor and mm wave voltage-controlled oscillator. It results in significant yield enhancement of the SiGe HBTs (from 25 % to 75 %) and VCOs (from 8 % to 85 %). The proposed method is can be extended for device, circuit, package, and system level integrated co-design since it can handle a large number of design variables without any assumptions about the component behavior. The proposed algorithm could be used by microwave community for design and optimization of microwave circuits and systems with greater accuracy while consuming less computational time.

AbstractThe first basic ingredient of heuristics is to build a solution. So, a first metaheuristic approach is to improve the process of building solutions. This chapter presents construction learning mechanisms. A typical example is artificial ants systems. Another technique is vocabulary building.

The current offshore wind energy market is not only focused on the design of WTG foundations, but also on the design of offshore infrastructures that lead to an improvement in the current grid connection system, such as artificial islands. For all these type of projects, caisson-type solutions can be applied with numerous advantages. The present article present three different projects in which caisson-type solutions were used: the foundation of a WTG (Gravi3® patent) in the Portuguese Coast, the foundation of a meteorological mast installed in Scotland and the design of an artificial island in the North Sea. The main advantage of this solution is the well-developed construction principle to build the caissons, which is based in the employ of a floating dock in a shelter area. As the caissons are cellular elements, the interior is empty; they float, so they are transported to the place in question to be deployed by means of filling with water the cells that comprised the caisson. This technology is rather used in Spain, being most of the kilometres of breakwater built using caissons thank to their high production rates. The three examples that will be presented in the article are proof of the versatility of this solution. Whereas the case of Gravi3® consists in a gravity based solution for WTG, which is comprised of 3 circular caissons connected by means of a steel tripod; the meteorological mast is formed by a rectangular caisson and a steel shaft. Finally, the artificial island is a mixed solution that uses caissons in the perimeter and hydraulic filling in the inner part. Furthermore, these solutions could be also applied in ports, integrating the WTG on the current or future dikes.

Abstract The Coiled Tubing (CT) industry has been growing and constantly pushing the boundaries of established operational limits. This is in line with well drilling paradigm shifts in the middle east. The latest well developments in exploration and well construction demand the deployment of new intervention equipment and technologies to cover the full length of the pay zones. Drilling horizontal wells that push length boundaries, requires new engineered transportation solutions and logistics for independently moving, spotting, and operating CT reels with large Outer Diameter (OD) spools and strings to service mega reach reservoirs. An operator requiring an offshore CT intervention into 40,000 ft deep wells from the artificial islands of the United Arab Emirates (UAE), encountered challenging crane and transportation limitations to lift heavy 2-3/8" CT reel weighing approx. 200,000 lb. This, combined with a desire to improve operational efficiency in moving from well to well and eliminating large mechanical lifts, led to the design of a custom-engineered transportation solution for the large diameter and heavy CT spool. This resulted in a cost reduction for cranes and avoided previously lengthy operations potentially taking several days to move the limited availability heavy 500T cranes onto and around the island. In addition, equipment rental and associated operating costs of all the service companies involved in the operation were reduced and allowed tighter timelines to be achieved. Innovative technology application, custom processes, and an engineered analysis of the transportation and operation were combined to provide the operator with a successful solution for CT reel movement from shore to the artificial island along with the operational execution using the same asset.

In order to harden or increase the soil impermeability formed when constructing hydraulic territories, injection cement-grouting technology can be effectively applied. Its obvious advantages include environmental safety, manufacturability, durability, and economic attractiveness. The soil conditions of artificial territories are characterized by extreme uniformity, which necessitates the use of various technical solutions for their hardening. The experience of applying various soil injection cement-grouting technologies that provide the specified efficiency of the design decisions made has been analyzed in the report.

Adopting Artificial Intelligence (AI) in the construction industry can improve construction processes, enhance competitiveness and boost the overall performance of the industry. However, the use of AI in the construction industry particularly in developing countries such as Nigeria is limited. This study examined the critical success factors for the diffusion of AI in the Nigerian construction industry. The study adopted a quantitative research design with the use of a questionnaire to elicit information from construction professionals in Lagos Island, Lagos, Nigeria. Data from the survey were analyzed with appropriate descriptive and inferential statistical tools. The study shows that institutional factors, behavioral factors, and cost factors were the most critical success factors for the diffusion of AI in Nigerian construction. Other factors included knowledge factors, infrastructure factors, technical factors, and trust factors. The study offers some insights into the critical success factors for the diffusion of AI in a developing country such as Nigeria.

To reduce solid wastes and recover useful resources, an artificial island in the deep-sea area was built and it was planned to use the sorted public fill as the replacement of sand in the land reclamation. The use of the public fill as the replacement of sand not only reduced the CO2 emission, but also shortened the construction period. Although the use of public fill gives benefits to environmental sustainability, the public fill is rarely used in Hong Kong for reclamation in the deep-sea artificial island. Furthermore, the short-term and long-term post-construction settlement due to surcharge load is a key issue in the reclamation work, while limited information of the physical and mechanical properties of the public fill could be found in the past engineering projects. In addition, there are many uncertainties and influencing factors in the construction site such as the surcharge load magnitudes, modes of the loading process, and the variability of geotechnical parameters. How these factors influence the mechanical behavior of the public fill is an interesting issue. This paper gives first-hand laboratory test results accompanied by theoretical analysis to address the mentioned issues. After a comprehensive and careful measurement of several basic engineering properties, such as bulk density, particle size distribution, and Atterberg limits, large-scale oedometer tests were systematically conducted to study the compressibility of the public fill. It is found both volume compressibility and consolidation coefficient decrease with an increasing axial effective stress. An interesting finding is that an increasing fines content with a certain range will lead to an increase in the compressibility of the public fill, indicating the fines content may need to be considered in the land reclamation works. In addition, remarkable creep could be observed if the current vertical stress is lower than the preloading pressure. After obtaining design parameters and ensuring allowable settlement through both in-house laboratory tests and in-situ field tests, the project in the technical paper may be a good reference for future land reclamation design and construction cases.

The present study aims to create an artificial beach in the municipality of Machico, as well as its complementary infrastructures, located on the south-eastern coast, in the municipality of Machico (Madeira Island). Machico´s beach sand consists of a mixture of black volcanic sand and round basalt stones. Usually, it has clear waters and a quiet sea. This beach also has a mooring infrastructure, thus allowing access to the sea. To achieve this study's main goals, it was initially carried out an extensive review and bibliographic research. Subsequently, a sand beach and its shelter groins were simulated and designed to hypothetically promote the retention of the sand and mitigate the tidal effects. In addition to model the beach dynamics, an extensive characterization of the extreme maritime regime was performed. A descriptive memory, a set of project execution plans, the construction contract documents/special technical conditions, the corresponding budget, and the Health and Safety Plan, were elaborated to complement this project. Some final remarks and conclusions were then presented, as well as some future projects that should be developed to deepen the knowledge of its main subjects.
