Today, a consistent segment of the world’s population lives in urban areas, and this proportion will vastly increase in the next decades. Therefore, understanding the key trends in urbanization, likely to unfold over the coming years, is crucial to the implementation of sustainable urban strategies. In parallel, the daily amount of digital data produced will be expanding at an exponential rate during the following years. The analysis of various types of data sets and its derived applications have incredible potential across different crucial sectors such as healthcare, housing, transportation, energy, and education. Nevertheless, in city development, architects and urban planners appear to rely mostly on traditional and analogical techniques of data collection. This paper investigates the prospective of the data science field, appearing to be a formidable resource to assist city managers in identifying strategies to enhance the social, economic, and environmental sustainability of our urban areas. The collection of different new layers of information would definitely enhance planners' capabilities to comprehend more in-depth urban phenomena such as gentrification, land use definition, mobility, or critical infrastructural issues. Specifically, the research results correlate economic, commercial, demographic, and housing data with the purpose of defining the youth economic discomfort index. The statistical composite index provides insights regarding the economic disadvantage of citizens aged between 18 years and 29 years, and results clearly display that central urban zones and more disadvantaged than peripheral ones. The experimental set up selected the city of Rome as the testing ground of the whole investigation. The methodology aims at applying statistical and spatial analysis to construct a composite index supporting informed data-driven decisions for urban planning.

Additive manufacturing processes have changed significantly in a wide range of industries and their application progressed from rapid prototyping to production of end-use products. However, their environmental impact is still a rather open question. In order to support the growth of this technology in the industrial sector, environmental aspects should be considered and predictive models may help monitor and reduce the environmental footprint of the processes. This work presents predictive models based on a previously developed methodology for the environmental impact evaluation combined with a technical and economical assessment. Here we applied the methodology to the Fused Deposition Modeling process. First, we present the predictive models relative to different types of machines. Then, we present a decision-making tool designed to identify the optimum manufacturing strategy regarding technical, economic, and environmental criteria. Keywords—Additive manufacturing, decision-makings, environmental impact, predictive models.

Growth as an inevitable human nature roots even in our business operation. Private entities, similarly, in seek of expansion and maybe more influence over their area of expertise, decide to go public in a certain point of time. The timing to move from private to public, indeed, is a critical factor in the future success of the business. In the traditional capitalist structure of this move, small private companies, which are defined by the Australian Securities and Investments Commission as those entities with consolidated revenue of less than $50 million per year, choose between sellout to a parent firm or Initial Public Offering (IPO). Both options have their own advantages and disadvantages. Yet, they are both complex, highly regulated, costly, and frustrating which are truly major drawbacks for small entities. Failure to go public caused by these drawbacks results in death of small businesses and loss of jobs which is followed by terrible socio-economic consequences. To avoid the conventional frustrating publicity of the private firms, in this article, utilization of cryptocurrency as the modern financial instrument is discussed. Digital currencies enable fast transition, globalization, grassroot economy, and social justice.

Calculation of the carbon footprint of cement concrete is a complex process including consideration of the phase of primary life (components and concrete production processes, transportation, construction works, maintenance of concrete structures) and secondary life, including demolition and recycling. Taking into consideration the effect of concrete carbonation can lead to a reduction in the calculated carbon footprint of concrete. In this paper, an example of CO2 balance for small bridge elements made of Portland cement reinforced concrete was done. The results include the effect of carbonation of concrete in a structure and of concrete rubble after demolition. It was shown that important impact of carbonation on the balance is possible only when rubble carbonation is possible. It was related to the fact that only the sequestration potential in the secondary phase of concrete life has significant value. Keywords—Carbon footprint, balance of carbon dioxide in nature, concrete carbonation, the sequestration potential of concrete.

Wastewater injection into oil and gas fields is implemented for various purposes via injection wells. Disposing of wastewater, which is mostly waste saltwater produced with hydrocarbons in oil and gas fields, into underground petroleum reservoirs are usually tied with environmental purposes. Injection of wastewater into geologic strata may encompass different applications: hazardous or non-hazardous wastewater disposal, enhanced recovery from petroleum reservoirs or merely wastewater storage. Aside from the purpose of wastewater injection, modeling of wastewater flow in porous media of underground rock strata can be challenging in different petroleum reservoirs and wells. In this study, a tight gas reservoir (TGR)—as a large-scale sustainable material to store wastewater—is considered to be studied for water disposal via a multistage fractured horizontal well (MSFHW) by numerical simulation. Host rock layer is considered to be initially saturated with low-pressure methane gas and water injection has to be performed through the hydraulic fractures of the MSFHW into the rock pore volume. Injection is performed under constant bottomhole flowing pressure and several sensitivity analyses are investigated to outline important rock characteristics in TGRs affecting performance of wastewater injection into them.

Underground carbon capture and sequestration (CCS) is a useful technique for separating this kind of greenhouse gas from atmosphere and store it under the surface of the earth. As a matter of fact, CO2 can be transferred to underground petroleum reservoirs which are initially contained oil and gas, or aquifers which are initially saturated with water. This kind of CCS takes place using an injection well which is drilled from surface to the target underground bedrocks. A shale gas reservoir (SGR) is a type of petroleum gas reservoir in which natural gas is stored in ultra-tight pores of the shale rock. In this study, a flow modeling analysis in SGR with a multi-stage fractured horizontal well (MSFHW) is conducted using numerical simulation. In this shale layer, a horizontal well is drilled and several transverse hydraulic fractures, for increasing the flow efficiency between the well and porous medium, are created. The studied SGR – a depleted reservoir acting as a macroscopic sustainable material for the CCS – is initially saturated with methane gas, and carbon dioxide is required to be injected for the storage. The most outstanding results of this study is about sensitivity analyses for SGR permeability with different conditions of gas adsorption and stress-dependent permeability which are from important features of SGRs. The results show a minor reduction in cumulative gas injection due to the effect of stress-dependent permeability in all measures for reservoir permeabilities. Furthermore, gas sorption shows a considerable positive correlation with CO2 storage response in high-permeability SGR and a minor increasing effect on SGRs with lower permeability values.

Membrane distillation (MD) is a thermally driven separation process. Despite many advantages over other membrane separation processes, pore wetting hampers the wide commercial applications of the MD process. In this paper, the effect of temperature and presence (or absence) of salt in the feed solution on the wetting properties of commercial polyvinylidene fluoride (PVDF) membrane during a period of eight weeks was investigated. Liquid entry pressure (LEP) and water contact angle (WCA) were employed to characterize the wetting properties of the PVDF membrane. The result shows that the temperature has a significant impact on the decrease of the contact angle of the PVDF membrane.

With the growing attention to smart buildings, local governments are seeking practical ways to optimize the energy consumption of commercial buildings. An ideal smart building is capable of monitoring its own energy consumption and adjusting the operation of electric devices, being lighting and air conditioners, based on the occupant behaviour. In this study, data had been obtained from the monitoring sensors in a commercial building located in the heart of Sydney from 2013 until 2020 on a 15-minute time intervals. The data derivation and analysis are intrinsically static at the moment which makes it difficult for building management to make instantaneous decision regarding the measures to be taken for a lower energy consumption. Using data analysis and visualization tools in Tableau, this study provides detailed insights about the trends in energy consumption in the given building. The outcomes facilitate the decision making for building management and can be seen as a milestone towards a dynamic optimization protocol in a bigger picture which is introduced in the second part of this study.

The adventurous human nature had recently expanded to extraterrestrial habitation. Public billion-dollar companies such as SpaceX and Blue Origin are investing extra ordinary capitals in space exploration. Australian Space Agency had also joined the space competition in 2018 in a so-called Mars mission. Although might sound far reaching, the idea of building human habitats on Mars requires well evaluated engineering design in the first stage as the cost of transporting equipment and materials as light as a kilogram to another planet is a massive financial burden. Throughout this passage, the effect of gravity, atmospheric pressure, and radiation on extra terrestrial buildings will be discussed. Following that a cylindrical structure as the most stable type of shell against internal pressure will be analyzed.

Many concrete technologists are looking for a solution to replace Fly Ashes that would be unavailable in a few years as an element that occurs as a major component of many types of concrete. The importance of such component is clear - it saves cement and reduces the amount of CO2 in the atmosphere that occurs during cement production. Wood Ashes from electrostatic filter can be used as a valuable substitute in concrete. The laboratory investigations showed that the wood ash concrete had a compressive strength comparable to coal fly ash concrete. These results indicate that wood ash can be used to manufacture normal concrete.
