Delivering sustainability therapy in a projectified world

This paper explores the apparent contradiction between the 'linearity' of most Sustainable Development projects, with time-bound and defined outputs achieved at a fixed cost, and an implied 'circularity' of the theory whereby there is no 'end'. Projects usually have clear parameters within which they are implemented, and the inclusion of elements such as the need for accountability, measurable impact and 'value for money' have grown in importance. It could be argued that we live in a 'projectified' and therefore linear world. The paper explores the potential contradiction between 'linearity' and 'circularity', and suggests that one way around this is to frame the project within a form of the Kolb Learning Cycle heuristic. This will facilitate a rationalisation from those implementing the sustainable development project as to why decisions are being made and for whom. If these questions are opened up to the project stakeholders, including beneficiaries, then the Kolb cycle could encourage learning and understanding by all involved. It could also provide Sustainability Therapy to those trapped in processes which they find orthogonal to their own perceptions. It is suggested that such learning, therapy and reflective practice should be a valid output of the sustainable development project, although typically the focus is only upon the final outputs and how they feed into policy. Ironically funders would be well advised to take a broader perspective in order to achieve true 'value for money' within such projects, even if learning is not an easily measurable or tangible outcome. These points are explored within the context of the wider literature and sustainable development projects undertaken in Malta and Lebanon.
Effect of Yoga Therapy on Health Outcomes in Women With Polycystic Ovary Syndrome: A Systematic Review and Meta-Analysis

The purpose of this study was to assess the effect of yoga therapy (YT) on health outcomes of women suffering from polycystic ovary syndrome (PCOS). Interventional studies, with postmenarchal and premenopausal females with PCOS who received YT, with any health outcome reported, were included. Scopus, Cochrane, PubMed, Embase, and Medline databases were electronically searched. Systematic review included 11 experimental studies, representing 515 participants with PCOS, out of which 2 randomized controlled trials (RCTs) were included for meta-analysis. Random effects model was applied using Review Manager Software version 5.4. 1 and strength of evidence was assessed using GRADEpro Guideline Development Tool, 2020. Meta-analysis showed that YT may significantly decrease menstrual irregularity (MD −.41, 95% CI −.74 to −.08), clinical hyperandrogenism (MD −.70, 95% CI −1.15 to −.26), fasting blood glucose (MD −.22 mmol/L, 95% CI −.44 to −.01), fasting insulin (MD −28.21 pmol/L, 95% CI −43.79 to −12.63), and homeostatic model assessment-insulin resistance value (MD −.86, 95% CI −1.29 to −.43). Strength of evidence was “low. ” In conclusion, YT may have beneficial effects on health outcomes in women suffering from PCOS. However, low strength of evidence suggests need of conducting well-designed RCTs to assess the efficacy of YT for PCOS.

Electrical Breakdown of a Metallic Nanowire Mesh

The electrical breakdown of a metallic nanowire mesh induced by Joule heating (i.e., melting) is investigated by solving the corresponding electro-thermal problem, where the effect of electromigration is neglected. A numerical computational program is firstly developed to simulate the temperature profile for a metallic wire mesh and investigate the melting current triggering the melting of mesh segment. The melting process of the mesh structure is investigated by analyzing the variation of melting current with regard to the melting propagation of mesh segment. On this basis, the melting behavior of a system of the mesh equipped with current source is predicted. For both current-controlled and voltage-controlled current source, local instability (i.e., at a constant current/voltage, several mesh segments melt simultaneously) and stable melting (i.e., the increase of current/voltage is necessary for the melting of mesh segment) will happen. Moreover, global instability (i.e., at a constant current, several mesh segments melt until the circuit of mesh opens) will occur only at the mode of current-controlled current source.
REVIEW OF SEARCH THEORY: ADVANCES AND APPLICATIONS TO SEARCH AND RESCUE DECISION SUPPORT: FINAL REPORT

Fundamental limitations inherent in manual search planning methods have severely limited the application of advances in several areas that could improve the efficiency and effectiveness of the U.S. Coast Guard's (USCG) search and rescue mission. These include advances in search theory, environmental data products, and knowledge of detection profiles for various sensors and of leeway behavior. The USCG's computerized search planning aids have not kept up with advances in these areas or with technology in general. This report reviews the history and recent advances of search theory and its application to a variety of search problems. It then reviews the history of the USCG's search planning methods, showing where search theory was initially applied, albeit it in a necessarily very limited way, and where later modifications departed from the theoretical basis of the original methodology. Several computerized search planning decision support tools are analyzed and compared, as are the differences between an analytic approach and a simulation approach. Results are summarized in a matrix. The USCG needs a new search planning decision support tool for search and rescue and other missions. This tool should use the simulation approach due to its power and flexibility as compared to analytic methods.
The Tower of London

The Tower of London was built in 1078 by William the Conqueror. He ordered the construction of the fortress to protect the Normans from the native English and symbolize his power. Throughout history the ever-expanding tower was used as a royal palace, an arsenal, a mint (i.e. a place where money is made) and even a zoo. In the 16 century, during the reign of Henry VIII, the Tower of London became a sinister prison, synonymous with terror, torture and death. Two of the King’s wives were beheaded in the Tower of London and over 50,000 people were executed. Today, the Tower of London functions as a museum and treasury. It is guarded by Yeoman Warders, a.k. a. the Beefeaters. They are former officers and sergeants of the British Services. They are called Beefeaters because, in the past, part of their salary was paid with beef! If you go to the Tower of London, you will see black ravens. According to legend, if the black ravens leave the Tower of London, it will be the end of the British monarchy.
A Many-Objective Optimization Based Federal Deep Generation Model for Enhancing Data Processing Capability in IoT

The rapid progress of artificial intelligence expands its wide applicability in Internet of Things (IoT). Meanwhile, data insufficient and data source privacy are key supply chain challenges facing IoT especially in the healthcare industry. To address this problem in healthcare IoT, in this article, we propose a skin cancer detection model based on federated learning integrated with deep generation model. First, we employ dual generative adversarial networks to address the problem of insufficient data. In addition, to improve the quality of generated images, we synchronously optimize the sharpness of images, Frechet inception distance, image diversity, and loss using knee point-driven evolutionary algorithm (KnEA). Then, we protect patient information privacy by training federated skin cancer framework. Finally, we employ the ISIC 2018 dataset to test the performance of the proposed training model under different situations, including using identically distributed data, nonidentically distributed data, a sparse convolutional neural network, and a fully connected convolutional neural network. The experiment results demonstrate that the accuracy and area under the curve reach 91% and 88%, respectively. This model can help resolve problems of insufficient data in smart medicine of IoT and protect the privacy of user data while also providing an excellent detection rate.
Systematic Assessment of Advanced "Sharp-Edged" Lifting Body Re-entry Configurations

The usefulness of an advanced, facetted, sharp-edged geometry is technically assessed for a typical re-entry configuration. A generic re-entry vehicle with on-orbit and payload return capability in the 100 kg class is selected as the baseline concept. Different aerodynamic shapes are investigated in a flyable configuration taking into account the trim requirements of the vehicle’s centre of gravity including a practical internal accommodation of subcomponents and payload. Sophisticated simulation techniques are employed including Navier-Stokes CFD and TPS-sizing based on unsteady heat flux calculations in combination with trajectory simulation. The calculated aerothermodynamic loads are used for the preliminary sizing of the ceramic TPS along the simulated flight trajectory, taking into account the underlying metallic structure. System masses and outer shape have been adapted in an iterative approach in order to find a promising configuration with maximum cross range and within an overall acceptable thermal balance. The paper further compares the most promising sharp-edged configurations with a conventional blunt re-entry capsule and with a non-winged lifting body type. The differences in mechanical and thermal loads, vehicle masses, aerodynamic efficiencies, and the achievable cross range capability of all these re-entry vehicles are outlined.

Voltage form factor control and reactive power compensation in a 25 kV electrified railway system using a shunt active filter based on voltage detection

AC railway traction systems are particularly susceptible to harmonic distortion. They are weak single phase networks often loaded with severely distorting SCR-based locomotive drives which continually change their point of physical connection to the network. For a public distribution system the total harmonic distortion is a clear measure of supply quality. However, for a traction system the more important parameter is the voltage form factor, which is directly related to the maximum power a locomotive can deliver. To minimise this form factor, this paper proposes the use of a shunt active filter that minimises the 3rd, 5th and 7th harmonic voltage components at the point of filter coupling. It is shown that the filter is effective in both compensating the pantograph voltage form factor, and providing reactive power to maintain the feeder voltage. The results are confirmed by detailed simulation using the EMTDC package.
Strongly reduced lattice thermal conductivity in Sn-doped rare-earth (M) filled skutterudites MxCo4Sb12−ySny, promoted by Sb–Sn disordering and phase segregation

CoSb3 thermoelectric skutterudite has been filled with rare-earth metals (M = La, Ce, Yb) and partially doped with Sn in specimens of MxCo4Sb12−ySny stoichiometry. This has been achieved under high-pressure conditions at 3.5 GPa in a piston-cylinder hydrostatic press. A structural investigation using synchrotron X-ray diffraction data reveals a phase segregation in twin skutterudite phases with filling fraction fluctuation and different unit-cell sizes. As a result of three effects acting as phonon scatterers, namely the rattling effect of M at the wide 8a cages of the cubic Im3̄ structure, the phase segregation, and the intrinsic disorder introduced by Sn substitution at the Sb sublattice, the total thermal conductivity (κ) dramatically falls to reach minimum values under 2 W m−1 K−1, well below those typically exhibited by other thermoelectric materials based upon single-filled skutterudites. The power factor is substantially enhanced to 1.11 mW m−1 K−2 in Yb0.5Co4Sb11. 6Sn0.4 with respect to the unfilled composition, as a result of the charge transfer promoted by the filler.
Subthreshold Potential Modeling of FinFET and QuadFET

A precise subthreshold potential model for the Quadruple FET (QuadFET) is presented in this thesis. The attempt of modeling the FinFET ("Fin" FET) in the same way failed, but the procedure of the attempt will still be presented in this thesis, and a conclusion of why this modeling did not work is given. For the QuadFET, an analytical solution of the inter-electrode potential distribution of the double-gate MOSFET (DG MOSFET) is used by performing a simple geometric scaling transformation. This is done with a high degree of precision due to structural similarities between the QuadFET and DG MOSFET, accounting for the dierence in gate control of the two devices. A parabolic approximation is then used to model the the cut-plane in the middle of the device, perpendicular to the electron ow from source to drain, of the QuadFET. The resulting analytical solution agrees very well with numerical simulations. For the FinFET, the same analytical solution of the DG MOSFET is used directly in the ground plane of the device, assuming that the electric elds going through the ground plane, into the thick substrate, is negligible. Conformal mapping is then used in the same plane as modeled in the QuadFET, that is the plane in the middle of the device, perpendicular to the electron ow from source to drain, resulting in an analytical solution of the FinFET. Since the potential curvature in the source-drain direction was neglected when making the three dimensional problem of the FinFET to a two dimensional one, the modeling failed. However, an attempt of modeling the transistor has been tested, the electrostatics of the device is better known, and a new way of modeling the device is briey discussed.

In it, you will find descriptions of characterization and measurement techniques, analysis methods, and the simulator implementation, model verification and validation procedures that are needed to produce a transistor model that can be used with confidence by the circuit designer. Written by semiconductor industry professionals with many years' device modeling experience in LDMOS and III-V technologies, this was the first book to address the modeling requirements specific to high-power RF transistors. A technology-independent approach is described, addressing thermal effects, scaling issues, nonlinear modeling, and in-package matching networks. These are illustrated using the current market-leading high-power RF technology, LDMOS, as well as with III-V power devices.
How far from Just-in-time are Portuguese firms? A survey of its progress and perception

As competition increases, Just-in-Time (JIT) manufacturing becomes an important issue in Portuguese industry. After a brief review of its history, elements, advantages and limitations, this paper presents the results of a postal questionnaire survey about JIT system sent to a sample of manufacturing firms in Portugal, with the aim of determining the degree of development, perception and status of JIT production in Portuguese industries. The findings suggest that the surveyed firms have a basic JIT perspective: a tool to reduce inventories, to increase quality and to eliminate waste. Despite the good perception of the JIT concept, less than 6% of the firms surveyed have the necessary conditions to successfully implement a JIT system.
OpenUP/MDRE: A Model-Driven Requirements Engineering Approach for Health-Care Systems

The domains and problems for which it would be desirable to introduce information systems are currently very complex and the software development process is thus of the same complexity. One of these domains is health-care. Model-Driven Development (MDD) and Service-Oriented Architecture (SOA) are software development approaches that raise to deal with complexity, to reduce time and cost of development, augmenting flexibility and interoperability. However, many techniques and approaches that have been introduced are of little use when not provided under a formalized and well-documented methodological umbrella. A methodology gives the process a well-defined structure that helps in fast and efficient analysis and design, trouble-free implementation, and finally results in the software product improved quality. While MDD and SOA are gaining their momentum toward the adoption in the software industry, there is one critical issue yet to be addressed before its power is fully realized. It is beyond dispute that requirements engineering (RE) has become a critical task within the software development process. Errors made during this process may have negative effects on subsequent development steps, and on the quality of the resulting software. For this reason, the MDD and SOA development approaches should not only be taken into consideration during design and implementation as usually occurs, but also during the RE process. The contribution of this dissertation aims at improving the development process of health-care applications by proposing OpenUP/MDRE methodology. The main goal of this methodology is to enrich the development process of SOA-based health-care systems by focusing on the requirements engineering processes in the model-driven context. I believe that the integration of those two highly important areas of software engineering, gathered in one consistent process, will provide practitioners with many benefits. It is noteworthy that the approach presented here was designed for SOA-based health-care applications, however, it also provides means to adapt it to other architectural paradigms or domains. The OpenUP/MDRE approach is an extension of the lightweight OpenUP methodology for iterative, architecture-oriented and model-driven software development. The motivation for this research comes from the experience I gained as a computer science professional working on the health-care systems. This thesis also presents a comprehensive study about: i) the requirements engineering methods and techniques that are being used in the context of the model-driven development, ii) known generic but flexible and extensible methodologies, as well as approaches for service-oriented systems development, iii) requirements engineering techniques used in the health-care industry. Finally, OpenUP/MDRE was applied to a concrete industrial health-care project in order to show the feasibility and accuracy of this methodological approach.
STABILISED INTERLOCKING RAMMED EARTH BLOCKS: ALTERNATIVES TO CEMENT STABILISATION

Southampton Solent University with the Good Earth Trust promotes projects in Africa that utilise interlocking rammed earth blocks. The earth used is typically a sandy clay or lateritic soil (red murram), stabilised with between 5-7% cement to improve the strength and durability of the blocks. Only a small quantity of water is necessary to compact the material in the ram and to allow for the hydration of the cement. The interlocks between the blocks reduce the need for 10mm mortar joints. Testing with different soils, surface treatments, lime and cement stabilisers were conducted at Southampton Solent University, UK (Browne, 2005). Ongoing tests at Makerere University in Uganda are researching the use of enzymes and polymers in providing innovative low carbon alternatives to cement. This paper introduces the use of this technology and assesses the different stabilising options to produce low carbon earth blocks.
A Stepping Stone

After 40 years of heavy usage on the existing northbound structure (60 years on the bascule span) of the Whitestone Expressway, the steel superstructure and concrete deck were badly deteriorated. The maintenance required for the grating deck on the bascule span became a recurring problem, and the fatigue evaluation of the existing bascule girders indicated that the girders were approaching the end of their remaining safe fatigue life. This article provides an overview of the rehabilitation goal for this structure, which was to correct the structural and geometric deficiencies of the existing northbound Whitestone Expressway to provide a safer roadway with improved operational features.
