μNet: Towards the first array of educational air shower detectors in Greece

We report on the design and the pilot phase of the [Formula: see text]Net project that aims for the active involvement of Greek high school students in the experimental procedures of astroparticle physics and especially in cosmic ray physics. Through the anticipated educational program, the students from the geographical area of Peloponnese will construct and operate educational cosmic ray telescopes deployed at their school laboratory and/or perform distant educational activities utilizing the extensive air shower array and the relevant remotely operated experimental setups of the Hellenic Open University Physics Laboratory.

Stereographic Reconstruction of Impact Microstructures using Optical and Electron Microscopy

Abstract This study reconstructs the pre-impact orientation of impact-generated μm-sized microstructures. The approach is illustrated using a sample from the basement dolerites of the Lockne impact structure, Sweden. Under the polarised light microscope, the microstructure appears as alternating augite-plagioclase wedges. The top-view of the microstructure is presented in the polished thin-section using light and scanning electron microscopy, while, the side-view is observed in focused-ion-beam trenches in a field emission scanning electron microscope. The top- and side view of the wedges are projected on a stereo net, which allows the determination of their 3D orientation. The wedges are thus found to have a dip of 08° towards 280°. The stereo net projections are then used to reconstruct the orientation of pre-impact boundary between augite-plagioclase, which had a dip of 15° towards 237°. This approach of combining light and electron microscopy with FIB trenching and projecting the data on a stereo net can be especially useful for reconstructing the pre-deformed state of impact-induced or tectonic μm-sized microstructures, which cannot be adequately analysed using a light microscope.

Life cycle GHG assessment of a building restoration: Case study of a heritage industrial building in Toronto, Canada

The refurbished Don Valley Brick Works’ Kiln Building, in Toronto, Canada, now the TD Future Cities Centre, is designed to have net zero carbon emissions. This is to be achieved through the reuse of existing materials and structures, selection of lower-carbon materials purchased from local sources, installation of renewable energy systems, natural lighting and improved thermal insulation of the building’s envelope, as well as developing a carbon offset strategy. The heritage designation of the building imposed restrictions on the design of the project (e.g., preventing insulation of exterior walls). In collaboration with the owner and constructor, the project team completed a life cycle assessment (LCA) consisting of an assessment of embodied emissions of the building’s restoration from cradle to grave, accompanied by a scoping estimate of greenhouse gas emissions associated with its future operational energy use. Primary construction data for the newly-added materials, transport, and construction activities were used. Life cycle inventory analysis and impact assessment were implemented in the One Click LCA software. Use phase carbon intensity was estimated using design and literature data. In addition to the ‘core and shell’ LCA scope typically applied to buildings, the team also tracked materials and processes that are often not included in building LCA studies such as HVAC, plumbing, and renewable energy systems.Embodied carbon for the restoration project, assuming a 60-year lifetime, is calculated as 1250 tonnes carbon dioxide equivalent (tCO2e). Sixty-nine percent of the carbon comes from the materials (extraction to manufacturing) used in construction, 20% is due to replacement of materials during the building’s service life, and most of the remaining 11% is from on-site construction energy (5%) and waste disposal at end-of-life (4%). The main building elements contributing to the embodied carbon are the renewable energy systems (31%) and the raised concrete floor (26%). Building envelope and foundation play minor roles, as they are mostly pre-existing. The embodied carbon added to the building through the restoration project is forecast to be balanced by savings in operational energy related to heating, cooling and lighting, within 3–13 years, depending on whether natural gas or electricity use are avoided, respectively.Uncertainties in the analysis arise from partial or missing data, modeling assumptions and future scenario unknowns. The model is sensitive to the useable lifetime of the building, local or non-local sourcing of building materials, modeling of certain components used in large quantities, and changes in the recycled content of steel. This study of a net zero carbon refurbishment project of a heritage building provides insights for assessments of future projects as such refurbishments become more commonplace. The methods and recommendations regarding data sources, data collection, and approach to uncertainty evaluation will be useful for LCA of any construction project.

Network Unavailable


 
 
 This paper problematizes assumptions of global all-pervading ‘available’ network culture by examining ‘network unavailability’ phenomenon in contemporary Chinese network culture through a post-colonial critique. The central argument of ‘network unavailable’ in China is contextualized by the performativity of the Great Firewall and the Golden Shield Project, Chinese media artist Fei Jun’s net art project Interesting World (2019) in the Venice Biennale and network happenings during the 2019 Anti-extradition Law Amendment Bill protests in Hong Kong. Through these examples the author argues that network culture in China is political and geopolitical and the discussion of networks should go beyond mere structuralism and emphasize the everyday life, tactical, and microscopic decision-making process.
 
 

The simple economics of white elephants

This paper shows that the concession model discourages firms from acquiring information about the future profitability of a project. Uninformed contractors carry out good and bad projects because they are profitable in expected terms even though it would have been optimal to invest in screening them out according to their value. White elephants are identified as avoidable negative net present-value projects that are nevertheless undertaken. Institutional arrangements that limit the losses that firms can bear exacerbate this distortion. We characterize the optimal concession contract, which fosters the acquisition of information and achieves the first best by conditioning the duration of the concession to the realization of the demand and includes payments for not carrying out some projects.

Direct measurement forest carbon protocol: a commercial system-of-systems to incentivize forest restoration and management

Forest carbon sequestration offsets are methodologically uncertain, comprise a minor component of carbon markets and do not effectively slow deforestation. The objective of this study is to describe a commercial scale in situ measurement approach for determination of net forest carbon sequestration projects, the Direct Measurement Forest Carbon Protocol™, to address forest carbon market uncertainties. In contrast to protocols that rely on limited forest mensuration, growth simulation and exclusion of CO2 data, the Direct Measurement Forest Carbon Protocol™ is based on standardized methods for direct determination of net ecosystem exchange (NEE) of CO2 employing eddy covariance, a meteorological approach integrating forest carbon fluxes. NEE is used here as the basis for quantifying the first of its kind carbon financial products. The DMFCP differentiates physical, project and financial carbon within a System-of-Systems™ (SoS) network architecture. SoS sensor nodes, the Global Monitoring Platform™ (GMP), housing analyzers for CO2 isotopologues (e.g., 12CO2,13CO2, 14CO2) and greenhouse gases are deployed across the project landscape. The SoS standardizes and automates GMP measurement, uncertainty and reporting functions creating diverse forest carbon portfolios while reducing cost and investment risk in alignment with modern portfolio theory. To illustrate SoS field deployment and operation, published annual NEE data for a tropical (Ankasa Park, Ghana, Africa) and a deciduous forest (Harvard Forest, Petersham, MA, USA) are used to forecast carbon revenue. Carbon pricing scenarios are combined with historical in situ NEE annual time-series to extrapolate pre-tax revenue for each project applied to 100,000 acres (40,469 hectares) of surrounding land. Based on carbon pricing of $5 to $36 per ton CO2 equivalent (tCO2eq) and observed NEE sequestration rates of 0.48 to 15.60 tCO2eq acre−1 yr−1, pre-tax cash flows ranging from $230,000 to $16,380,000 across project time-series are calculated, up to 5× revenue for contemporary voluntary offsets, demonstrating new economic incentives to reverse deforestation. The SoS concept of operation and architecture, with engineering development, can be extended to diverse gas species across terrestrial, aquatic and oceanic ecosystems, harmonizing voluntary and compliance market products worldwide to assist in the management of global warming. The Direct Measurement Forest Carbon Protocol reduces risk of invalidation intrinsic to estimation-based protocols such as the Climate Action Reserve and the Clean Development Mechanism that do not observe molecular CO2 to calibrate financial products. Multinational policy applications such as the Paris Agreement and the United Nations Reducing Emissions from Deforestation and Degradation, constrained by Kyoto Protocol era processes, will benefit from NEE measurement avoiding unsupported claims of emission reduction, fraud, and forest conservation policy failure.

Modeling Coastal Marsh Restoration Benefits in the Northern Gulf of Mexico

Extensive salt marsh restoration is expected in the northern Gulf of Mexico over the next several decades, funded in part by settlements from the 2010 Deepwater Horizon oil spill. Understanding the ecological benefits of restored marshes over time is integral to setting appropriate restoration targets and performance criteria and in determining the restoration area needed to achieve desired restoration goals and offset quantified natural resource injuries. We present a method for quantifying anticipated ecological benefits associated with marsh restoration projects, particularly marsh creation or enhancement through the placement of dredged material, in the northern Gulf of Mexico. Using salt marsh vegetation (percent cover, aboveground biomass, and belowground biomass) and indicator faunal species (periwinkle snails and amphipods) as representative marsh community components, we used resource equivalency analysis (REA) to model projected ecological benefits over time and quantified total net project benefits for a hypothetical marsh creation project in Barataria Bay, Louisiana. Sensitivity analysis of the resulting model suggests that the recovery trajectories for each marsh component were the most important drivers of modeled restoration benefits and that model uncertainty was greatest for marsh fauna, which has limited data availability compared to marsh vegetation and high natural variability. Longer-term monitoring at restored restoration sites and/or targeted monitoring of older restoration projects would reduce variability in the recovery trajectories for the marsh community components examined in this case study and improve the reliability of the REA model for projecting benefits associated with salt marsh restoration.

Cost benefit analysis on establishing a machinery hiring-out centre in Sri Lanka

Reduction of labour is one of the major concerns in the recent past in the agriculture sector of Sri Lanka recent past. Agriculture has become less attractive to youth. Even though mechanization will be one of the better solution to overcome this problem, high cost of capital requirement restricts small land owners to move into mechanization. The Department of Agriculture (DOA) has identified this issue and proposed to establish machinery hiring-out centres to enable the farmers to obtain services at a reasonable rate. This study aimed at estimating the financial feasibility and economic feasibility of hiring-out centres over the project economic life of 10 years. Financial feasibility analysis included financial statement analysis, net project worth assessment and sensitivity analysis. For the purpose of economic analysis, financial prices were converted to shadow prices using the shadow exchange rates and project worth was recalculated. In project analysis, it is common to have multiple IRR rates, which was answered with MIRR estimation representing the actual IRR. Results of the study revealed that the project is financially viable and generates positive net income of Rs. 27 million annually throughout the period, generation of net cash inflow of Rs. 257.7 million, and accumulation of net assets of Rs. 277.7 million. Project worth analysis resulted in a positive financial NPV of Rs. 7.6 million, IRR of 19%, MIRR of 13% and a B/C ratio of 1.03. However, the IRR value and B/C ratio is contradictory to each other due to multiple IRR values and limited time frame of analysis of 10 years and this was addressed through MIRR measure, which is the optimal IRR value of the project and is consistent with the B/C ratio. Economic feasibility analysis showed a positive ENPV of Rs. 10.1 million, EIRR of 28%, EMIRR of 18% and a B/C ratio of 1.05. The study concluded that establishment of a machinery hiring-out centre is feasible at financial and economic conditions in a minimal risk environment. Consequently, government may have a role in facilitating the project implementation with suitable subsidy scheme till the project maturity. Development of a suitable implementation design would be the next step such as a PPP model.

Sustainable Housing: Understanding the Barriers to Adopting Net Zero Energy Homes in Ontario, Canada

Buildings in Canada account for a significant amount of greenhouse gas (GHG) emissions and net zero energy building technology has been identified as part of the solution. This study presents a conceptual model identifying barriers to the adoption of net zero energy housing and tests it by administering a survey to 271 participants in a net zero energy housing demonstration project in Toronto, Canada. Using multivariate correlation and multi-linear regression analyses this study finds that of all the innovation adoption variables it was the construction and design quality that was the most significant contributor to the adoption of a net zero energy home by a potential home owner. This study found that the (a) extra cost compared to a conventional home, b) lack of knowledge about the technology associated with a net zero energy home or (c) not knowing someone who owned a net zero energy home were not significant barriers to accepting net zero energy homes. Our results suggest that policy-makers should promote the diffusion of net zero energy home technology by encouraging housing developers to include net zero energy homes in their collection of model homes, with an emphasis on quality design and construction. Furthermore, engaging in trust building initiatives such as education and knowledge about the technology, its related energy cost savings, and the environmental benefits would contribute to a greater acceptance of net zero energy homes.

RECYRON®: Idea to Innovation to Technology in Zero-Waste Ironmaking

Waste products are actually raw materials in disguise, waiting for a smart person to identify them and put them back into use by an appropriate process. RECYRON® is a novel technology for a zero-waste ironmaking process. This process is designed to recycle all possible raw material wastes (RMWs) from an integrated steel plant to produce direct reduced iron (DRI). RECYRON® takes care all RMWs of steel plants and iron ore mines, starting from superfine ores, coke breeze, sinter dust and BF dust and sludge, mill scale, just to name a few. RECYRON® uses a simple technology like briquetting to its utmost potential to agglomerate all the wastes, and thereafter reduces it by using a rotary kiln. The reduced briquettes with high metallic iron could be used in mini-mills having electric arc furnaces (EAF), or to charge in the blast furnace to lower the coke rate as much as possible. The process is also able to generate power as the by-product. RECYRON® offers several advantages in parallel, such as reduction of landfill, complete utilization of raw materials, low CO2 footprint, and last but not the least, a highly profitable process. The financial aspects such as estimated CAPEX and OPEX along with the NPV (Net Project Value) and IRR (Internal Rate of Return) for plants are also discussed in this article.

Art on the Internet and the Digital Public Sphere, 1994–2003

Author(s): Driscoll, Megan Philipa | Advisor(s): Kwon, Miwon | Abstract: This dissertation narrates the development of internet art, a diverse set of practices united by their interrogation of the technological, social, and/or political bases of computer networks. Covering the period from 1994, when internet art coalesced around the rise of the World Wide Web, to 2003, when both internet art and internet culture writ large began to respond to the rise of social media and web 2.0 technologies, the dissertation homes in on specific net art projects that variously engaged or challenged this period’s most persistent claim: that the internet is a new, digital public sphere. By studying how these artworks critiqued this claim, the dissertation uncovers three major models through which net art has asserted the publicness of computer networks—as an interpersonal network that connects or unites strangers into groups; as a virtual space akin to physical spaces of public gathering, discourse, and visibility; and as a unique platform for public speech, a new mass media potentially accessible to all.Claims for the public status of computer networks rest on their ability to circulate information and facilitate discussion and debate. This definition of publicness is rooted in the concept of the classical public sphere as theorized by Ji?½rgen Habermas. The dissertation thus reviews Habermas’s model of the classical public sphere, and its most significant critiques, in order to interrogate the terms of a digital public sphere. The dissertation also engages Michael Warner’s work on the formation of publics, counterpublics, and the mass-cultural public sphere; Oskar Negt and Alexander Kluge’s analysis of shared experience as the foundation of the formation of public spheres and the role of mass media in this process; Henri Lefebvre’s articulation of the social production of space; and Gilles Deleuze and Alexander Galloway’s respective analyses of the role of network logics in systems of control. As a whole, the dissertation provides an historical account and critical analysis of internet art that encompasses not only its technological evolution but also its confrontation with the claims of publicness upon which our understanding of computer networks, and the art made on and about them, are founded.

Approachable ZEB (Zero Energy Building) (Part 1) - Current situation of our latest projects for ZEB -

We introduce the outline of the ZEB buildings we designed. Then, we analyse the plots on the ZEB chart, the completion year, the building type, the characteristics of these building, and the possibility of realizable ZEB, etc. And we mention the planning method to achieve ZEB Ready, and Nearly ZEB with less cost. And in this report, the breakdowns of reduction rates with reference to the standard energy consumption are described in figures of energy indicator in all these ZEB ready to Net ZEB projects. Such descriptions are also rare in WSBEC. Also, it seems that there is little description in WSBEC that refers to the relationship between the increase in investment costs and the reduction in energy costs. Taking care of the the clients, we do not mention in this report, but we will make oral comments at the oral presentation.

Facts and figures of clinical pathways in Italy: results from the PDTA Net project.

The approval of clinical pathways (CPWs) represents a key step to focus the care management on the patient. The PDTA Net project, by ReS Foundation and CINECA, aims to create a reference tool to study how the local organizational models influence healthcare and clinical outcomes. The article shows the analysis of all CPWs approved by Italian Regions and Autonomous Provinces until 31/12/2018. The search for documents was performed on the institutional websites through specific keywords. CPWs were filled into a database, according to the Region, publication year, disease of interest (distinguishing between chronic diseases with high epidemiological impact and rare diseases) and relevant clinical area. All documents were analyzed by geographical and temporal distribution, the latter also according to ministerial measures. From 2005 to 2018, 536 Regional CPWs were approved (316 for chronic diseases with a high epidemiological impact and 220 for rare diseases). The Regions with the highest number of CPWs of chronic diseases were Umbria (34 CPWs) and Piemonte (33). The most addressed clinical areas were: oncology (72), neurology (60), cardiology (34) and metabolic disorders (22). The most issued diseases were: diabetes (17), trauma/polytrauma (15), chronic obstructive pulmonary disease and multiple sclerosis (12 each), stroke (11), rheumatoid arthritis, breast cancer and colorectal neoplasms (10 each). The publication of the documents was affected by ministerial measures (Balduzzi Law, National Chronicity Plan, Diabetic Disease Plan and National Dementia Plan). The majority of CPWs on rare diseases was retrieved in Regions with activated Rare Disease Networks: Lombardia (110 CPWs), Lazio (64) and Toscana (17). This study showed that, to date, in Italy there are several CPWs published at Regional level, nevertheless their structure and application are heterogeneous and strongly influenced by the National Plans. All analyzed documents are available through the web platform of the project https://fondazioneres.it/pdta/. This project could be useful for health system stakeholders, in order to encourage the transition to new health governance and making CPWs effective governance tools.

Of Mice or Men: Management of Federally Funded Innovation Portfolios With Real Options Analysis

The aerospace industry is a rich source of innovation and novel technologies. However, structural drivers, such as product complexity and stringent performance requirements, inhibit the uptake of new technologies and present challenges to portfolio management specific to technology-rich environments. Although project risk is often managed through staged funding processes associated with intermediate milestones, this process is typically decoupled from portfolio valuation. In this paper, we use a simple real options binomial tree model to value the National Aeronautics and Space Administration portfolio funded through the Small Business Innovation Research program, accounting quantitatively for the funding stages and future opportunities accompanying technology infusion. For the 2009 portfolio, the average net project investment is $166k, suggesting the important role that early-stage funding plays in launching innovation efforts. We study the staged architecture to offer insight to managers of commercial and public portfolios alike.

Project Scheduling with Simultaneous Optimization, Time, Net Present Value, and Project Flexibility for Multimode Activities with Constrained Renewable Resources

Project success is assessed based on various criteria, every one of which enjoys a different level of importance for the beneficiaries and decision makers. Time and cost are the most important objectives and criteria for the project success. On the other hand, reducing the risk of finishing activities until the predetermined deadlines should be taken into account. Having formulated the problem as a multi-objective planning problem, the present study aims at minimizing the project completion time as well as maximizing the net present value and project flexibility by taking into account the resource constraints and precedence relations. Here the flexibility of project is calculated by considering a free float for each activity and maximizing the sum of these flotation times. Although most of the researches considered the resources as non-renewable resources, here the resources are considered as renewable ones. Moreover, performing each activity may be possible in various states of using resources (mode) which can change the project completion time and cost. Owing to the complexity of the problem, the Multi Objective Simulated Annealing Meta-heuristic Algorithm is used to solve the proposed model. In doing so, first a feasible answers is proposed and then, using the aforementioned algorithm, it was attempted to find Pareto answers. For accrediting the algorithm, four benchmark problems have been considered. Since the algorithm performed well in finding the optimal answers to the benchmark problems, it was used to find the optimal answer of large scale problems.

The Effect of Physical and Cognitive Decline at Older Ages on Work and Retirement: Evidence From Occupational Job Demands and Job Mismatch

As workers age, their physical and cognitive abilities tend to decline. This could lead to a mismatch between workers’ resources and the demands of their jobs, restricting future work. We use longitudinal data from the Health and Retirement Study (HRS) linked to detailed occupational characteristics from the O*NET project to investigate how mismatches between job demands and workers’ resources in two physical and two cognitive domains affect retirement outcomes. We estimate how changes in physical and cognitive resources as well as their interactions with occupational job-demands affect changes in 1) subjective reports of work-limiting health problems; 2) mental health; and 3) subjective probabilities of working past age 65. We also estimate hazard models for transitions from full-time work to retirement. We found that declines in physical and cognitive resources are strong predictors of all outcomes: Fewer resources lead to greater reporting of work-limiting health problems; decline in mental health; smaller subjective probabilities of working full-time past age 65; and more transitions from work to retirement. The interaction of resources with job demands, however, is only statistically significant for workers with large-muscle limitations who are more likely to report changes in outcomes when they work in occupations that rely heavily on physical strength. In contrast, the effects of declines in fine motor skills and cognition do not show statistically significant differences by occupational job demands. It appears cognitive and fine motor skills, at least as measured in the HRS, are universally important determinants of working, not specific to certain occupations.

Innovating the Urban Water System: Achieving a Net Zero Water Future Beyond Current Regulation

Recent extreme climatic events and failing infrastructure have increased awareness of the need for expanded resilience within urban water systems. Architects and engineers are more seriously considering integrating water capture and reuse technologies into projects; yet, the systems necessary to meet net zero water resilience are not currently legal for commercial use. This paper investigates the regulatory changes necessary to accommodate net zero water projects in Arizona. Institutional innovation in three critical systems—making rainwater potable, reusing water on-site, and decentralizing wastewater treatment—is needed to implement existing technology. Extrapolating from the removal of the identified barriers, this article sets forth a regulatory pathway for regenerative water design. For urban water reinvention to occur, institutional innovation will be as important as technological innovation.

On certain development aspects of an ipsas-based system-target approach to evaluation of net asset sustainability level projects in high-rise construction

Problems of accounting and reporting of net assets and the procedure of their formation taking into account the specifics of the economic and legal status of property of a non-commercial autonomous institution are some of the most controversial in the accounting for entities of the public sector. The study focuses on justification of accounting rules for net assets of public sector entities. The methods used in the study are as follows: comparison, synthesis, analysis, logical approach, and system approach. The article examines legal aspects and specifics of recognition of assets of public sector entities in accordance with IPSAS standards (International Public Sector Accounting Standards are a set of accounting standards issued by IPSASB (Council for International Financial Reporting Standards for Public Sector Organizations) used by state-owned enterprises worldwide in preparation of financial statements as of the 31st of August, 2015. The most crucial factor in the modeling of key performance indicators of the system-target approach to estimation of the sustainability level of net assets on the basis of IPSAS is a multicriterial evaluation of the basic management strategy for quality system elements used in operational and strategic planning projects operations in high-rise construction. We offer an alternative evaluation of assets due to be returned to the right holder (the state controller) in the event of liquidation of a public sector entity.

Business Management in Sustainable Buildings: Ankara-Turkey Case

The concept of the sustainability is described as efficiently and effectively consuming of exhaustible and recyclable sources of the world. A sustainable building implements sustainability criteria in its life cycle, and business management is the process by which an organization uses its resources in the most efficient way to reach its goal. From the beginning, sustainable building proves their differences from the conventional buildings. Sustainable buildings are resource-efficient and environmentally responsible structures in terms of energy consumption, construction principles, siting, renovation and maintenance throughout its life cycle while conventional buildings are more traditional in these matters. The differences are observable especially in costs and expenditures. It is possible and feasible to compare and contrast the design, construction and management costs of both types of structures. Thence, contributions of sustainable buildings are priced favourably in terms of ecological and sociological aspects. In this context, a prospective projection can be made considering the extra costs of sustainable structures, as well as the consumption profits due to the use of less energy than conventional construction. Considering this, it is possible to project consumption savings in long term. By calculating a forward-looking net cash flow projection, it can be forecasted how much time it will take to cover the extra cost. When making decisions, investors always contemplate maximum profitability. Within the scope of this study, costs of sustainable and conventional buildings will be compared and contrasted through precedence of a sustainable building certificated and non-certificated building. It will be analysed in which time period the initial cost difference between them will be compensated totally and partially. Furthermore, an efficiency analyses will be done in the scope of the necessities and expenses of these businesses.
