description: The presence of outliers (anomalous values) in synthetic aperture radar (SAR) data and the misspecification in statistical image models may result in inaccurate inferences. To avoid such issues, the Rayleigh regression model based on a robust estimation process is proposed as a more realistic approach to model this type of data. This paper aims at obtaining Rayleigh regression model parameter estimators robust to the presence of outliers. The proposed approach considered the weighted maximum likelihood method and was submitted to numerical experiments using simulated and measured SAR images. Monte Carlo simulations were employed for the numerical assessment of the proposed robust estimator performance in finite signal lengths, their sensitivity to outliers, and the breakdown point. For instance, the non-robust estimators show a relative bias value $65$-fold larger than the results provided by the robust approach in corrupted signals. In terms of sensitivity analysis and break down point, the robust scheme resulted in a reduction of about $96\%$ and $10\%$, respectively, in the mean absolute value of both measures, in compassion to the non-robust estimators. Moreover, two SAR data sets were used to compare the ground type and anomaly detection results of the proposed robust scheme with competing methods in the literature.

description: Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) is a wireless technology used in billions of devices. Recently, several Bluetooth fuzzing studies have been conducted to detect vulnerabilities in Bluetooth devices, but they fall short of effectively generating malformed packets. In this paper, we propose L2FUZZ, a stateful fuzzer to detect vulnerabilities in Bluetooth BR/EDR Logical Link Control and Adaptation Protocol (L2CAP) layer. By selecting valid commands for each state and mutating only the core fields of packets, L2FUZZ can generate valid malformed packets that are less likely to be rejected by the target device. Our experimental results confirmed that: (1) L2FUZZ generates up to 46 times more malformed packets with a much less packet rejection ratio compared to the existing techniques, and (2) L2FUZZ detected five zero-day vulnerabilities from eight real-world Bluetooth devices.

description: Two main strategies should be implemented to decarbonise the energy sector: substituting fossil fuels with renewable energies, and increasing system efficiency. Both strategies pose challenges for today's energy systems and their operators, because renewable energy is mainly decentralized, not always predictable, and introduces a degree of volatility into grids. Multi-energy systems, which incorporate multiple energy sectors, allow flexibility options to be used across energy carriers and thus further increase system flexibility. In addition, these multi-energy systems can also improve the overall energy efficiency. They enable cascaded energy use and allow for seasonal storage between different energy carriers. A comprehensive system modelling framework should consider all profound interactions between relevant system control variables. The aim of this proposed paper is to show the correlation between major aspects of grid based MES and how they can be combined in a system modelling framework.

description: This study is dedicated to comparing the levelized operating costs of various types of power units and energy carriers for electric vehicles: battery systems, hydrogen-air fuel cells, and aluminum-air electrochemical generators. The operating cost considers the power unit itself, energy carrier, and associated charging infrastructure. Each electric vehicle type was calculated in two versions: a passenger electric car and a light duty commercial truck. It is shown that the most cost effective power unit is an aluminum-air generator. Its levelized operating cost is 1.5–2 times lower toward a battery system and 3–4 times lower toward fuel cells. The advantage of aluminum as energy carrier is the low cost and simple design of the corresponding power unit and charging infrastructure compared to those for battery and hydrogen power units. Aluminum recycling is key to its efficient use, this concept may become competitive in the aluminum-producing countries.

description: In the transition towards 4th generation district heating (4GDH), supply and demand side measures have to be coordinated better than in previous generations of district heating (DH). Building’s heat demand has to be reduced, and heating installations as well as consumer behaviour have to be adapted so as to be compatible with and support lower network temperatures. It is therefore necessary to investigate and understand how consumers can be meaningfully and strategically included in the transition towards 4GDH. This paper provides a literature review of the consumer levels role in 4GDH in the transition towards 100% renewable energy systems. Current literature of 4GDH have been investigated to identify the connection and involvement of consumers in the transition. Even though consumers within the existing building mass have a large role in the transition in terms of heat savings and instalment of energy efficient technologies in the buildings are almost none of the scientific literature addressing how these actions should be implemented at consumer level. From the results of the analysis it is recommended that further research should investigate how to strengthen the coordination between supply and demand sides in order to secure the right initiatives are implemented in the right order.

description: This paper illustrates the application of various forecasting methodologies in constructing multiple scenarios for the state of Maryland using Long term Inter Industry Forecasting Tool that tracks inter-industry outputs at a macro scale, and State Employment Model that disaggregates these outputs to the states. We then use accessibility, land availability and observed relationships of employment categories to distribute employment at a county level. In this paper, we identify the possible advantages and pitfalls of using large scale economic models to drive employment forecasts at the county level. This framework allows for simulating the implications of macroeconomic scenarios such as changes in exchange rates and unemployment levels, as well as local land use and transportation policies on local employment and demographics. In particular, we focus on two scenarios as test cases both of which involve very different ideas about how future might unfold and their effects on land use and transportation policy prescriptions. One of the scenarios involves, among others, rises in health care spending over the next few years and the other involves increases in energy prices. As will be shown, they have different spatial effects and suggest different policy actions on the part of various governments.

description: This paper presents a comprehensive model on the expansion of non-fossil technology to evaluate the impact of increasing their share in Iran’s electricity supply system. This analytical approach is based on system dynamics (SD), with an emphasis on the expansion of non-fossil fuels in the supply side of this model. Four emerging electricity generation technologies of solar photovoltaics, wind turbines, expansion turbines, and hydro power are considered in the model, and the effect of electricity price on increasing the motivation of the owners of non-fossil fuel power plants to guarantee their 20% share is examined. The Iranian government has set a target of a 20% share of non-fossil fuel electricity generation by 2030, whose main result is reducing GHG emissions to achieve the targets pledged under the Paris Climate Accord. Therefore, we developed four scenarios with different expansions of non-fossil technologies in Iran’s electricity system to investigate the goal, though various barriers exist that must be addressed through effective policies in order to facilitate the expansion of non-fossil fuel power plants in the electricity supply system. The findings demonstrate that electricity price must be determined based on the costs of non-fossil technologies, as well as based on fossil fuel prices which are low in the current energy supply system. In conclusion, the Paris Climate Accord criteria is achieved with a 20% growth of non-fossil fuels and increasing electricity price to 920 IRR/kWh in 2030.

description: This paper illustrates the use of scenarios in land use, environmental and transportation planning in and around the State of Maryland. Different assumptions about futures result in different patterns of growth with differential impacts on particular sectors of the economy. Such different patterns require formulation of contingent plans as well as robust plans. In this paper, we illustrate the quantitative modelling methodology of loosely linked economic demographic, transportation and other impact assessment models in constructing two scenarios; one of which represented the best possible guess about the continuation of the future and other involving rapid changes to energy prices and Federal spending. We illustrate the spatial development outcomes and the transportation and environmental plans that are necessary to deal with these different outcomes. Further, we illustrate that different planned actions have different efficacies in different futures and thus multiple futures should be carefully considered. Finally, we illustrate the notions of contingent plans and robust plans.

description: The Job Creation Tax Credit (JCTC) program is one of the five major Smart Growth Programs initiated by the State of Maryland in 1996 and amended in 1997.  Like other tax credit programs it is intended to create jobs, but it is also a place-based policy in the sense that eligibility is limited to jobs created in Priority Funding Areas (PFAs). This paper examines whether the JCTC program has furthered the goals of smart growth by concentrating job growth within well defined regions of the state. Towards this end, both the number and the relative share of employment inside and outside of the PFAs are compared using three econometric models. The empirical analysis examines employment in five economic sectors ((1) primary, (2) manufacturing, (3) transportation, communication and utilities (T.C.U.), (4) finance, insurance and real estate (F.I.R.E.) and (5) services) over the years (1994 to 1998) using ZIP Code data. The result shows that jobs in the T.C.U. and services industries have responded to the state incentive program while three other sectors have not; the distribution of jobs in the primary sector have grown counter to the state incentive policy and jobs in manufacturing and F.I.R.E. have been unaffected by the program.

description: Ensuring the supply of affordable energy, improving energy efficiency and reducing greenhouse gas emissions are some of the priorities of the governments of several countries. The pursuit of these energy goals has triggered interest in the exploration and usage of Renewable Energy Sources (RES), which can be particularly appropriate for island systems as is the case of Cape Verde. This work proposes a generation expansion planning model for Cape Verde considering a 20 years’ period. Different scenarios were analysed, each one representing a possible RES contribution for electricity production, reaching a 100% RES share. The results demonstrate that the increase of the RES in the system will lead to an increase of the total cost of energy. However, both CO2 emissions and external energy dependency of the country significantly decrease. The seasonality of the RES resources, and in particular of wind power is shown to be one of the most important challenges for the effective uptake of such a renewable power system. While the proposed model allowed already to present some useful scenarios, it becomes also evident the need to expand the analysis, and the paper concludes with directions for future research.

description: Selection of a location for a solar power plant is critical due to conﬂicting objectives7 in energy planning. The main objective of this study is to apply a methodology based on8 an Analytic Hierarchy Process (AHP), in order to assess potential locations of solar power9 projects in Colombia. This study takes into consideration technical-economic, social, and10 environmental-risk criteria based on data from the National Survey on Living Conditions in11 Colombia (NSLCC) and The Institute of Hydrology, Meteorology and Environmental Stud-12 ies (IDEAM). Eight departments were chosen representing diﬀerent regions of the country,13 with diﬀering levels of irradiation as well as distinct social and cultural living conditions. The14 methodology presented here can be used as a design tool for energy policy by utilities com-15 panies, providers, investors and academic researchers in the selection of locations for solar16 power projects. The results show the selection of alternatives using the AHP methodology.

Starting with a fully random-generated set of small molecules we score them by docing score, ADME(T) parameters and poses to estimate specified objective function. Then we use Bayessian approach to select a number of support points and recreate a new generation using them.

We use generative models based on RNN-autoencoders to create an internal representation of molecules by their SMILES strings and then use this representation to create novel molecules with target properties similar or increased.

description: A methodology focused on technology evaluation is proposed to give a footprint of the development potential of energy technologies in Italy. The approach focuses on the impact on climate, the potential in terms of R&D, the competitiveness of Italian companies and their diffusion on the territory. A reference Catalogue was realised in the framework of the ‘Technical Board on Decarbonisation of the Economy’, established by the Italian Presidency of the Council of Ministers. 36 datasheets, containing quantitative and qualitative information on Technology Readiness Level (TRL), efficiency, environmental and economic impacts and policy aspects were filled by 70 experts for each technology. Some data were extracted from the Catalogue - TRL, CO2 emissions, developers, and centres of excellence - and further analysed with other information relating to the Italian production and innovation system collected from the National Enterprise Registry (ASIA). Companies and research centres are involved in development of technologies based on Renewable Energy Sources (RES) and Energy Storage (ES) with different levels of TRL and high potential for mitigating effects on climate. However, their distribution shows a rather inhomogeneous presence at territorial level. This evaluation provided useful elements to elaborate policy measures to support the diffusion of energy technologies.

Reliability constrained planning and sensitivity analysis for Solar-Wind-Battery based Isolated Power System
Creators: name: Paliwal, Priyanka
Publisher: name: International Journal of Sustainable Energy Planning and Management
Year: 2020

description: Isolated power systems have emerged as a practical substitute to grid extension for electrification of remote areas. The environmental hazards associated with conventional sources of energy like diesel and coal has forced system planners to resort to renewable energy sources(RES) based technologies such as solar and wind. Increased penetration of RES can effectively cut down system operating costs but can create reliability issues owing to their unpredictable nature. The risk of lower reliability standards can significantly hamper utilization of these sources on large scale. Thus an effective backup system is needed in order to ensure reliability standards. The backup is provided either by diesel generators or energy storage systems. The intermittent nature and cost intensive structure of RES based DGs makes it essential to perform sensitivity analyses for optimal system planning. In this paper, reliability and cost based sizing of solar-wind-battery storage system has been carried out for an Isolated hybrid power system(IHPS). Sensitivity analyses are performed by studying the effect of addition/removal of RES based DGs and storage units on system reliability. Considering variable nature of solar and wind sources, modelling of solar irradiance, wind speed and generator availability has been done using appropriate probability density functions. Dual reliability indices have been used for determining system reliability. For solving optimal sizing problem, a stochastic optimization technique Particle Swarm Optimization(PSO) has been employed. A new index termed as Incremental cost of reliability has been utilized in order to assess the additional investment required to improve reliability standards. Optimal sizing study in conjunction with sensitivity analyses facilitates a deeper insight into system planning.

description: Europe is facing a great technical and regulatory challenge in transitioning the energy supply from fossil fuels to sustainable renewables. Within the heating sector, the Heat Roadmap Europe studies has demonstrated large potentials and benefits from expanding district heating (DH) throughout the continent. However, as a monopoly structure, district heating grids require well thought-out regulatory regimes to be accepted by cities and consumers. Founded upon the approach of concrete institutional economics, this paper contributes to the literature on DH regulation by reviewing and describing regulatory experiences across Europe. The paper demonstrates that a wide range of regulatory mechanisms are available for implementing DH.

description: Kazakhstan is currently committed to develop its renewable energy resources. In 2012, the government introduced a low-carbon energy strategy to reduce the production of air pollutants, including anthropogenic CO2e, and to increase the share of clean energy up to 50% of total consumption by 2050. As a contribution to this strategy, this paper presents a comparison in techno-economic performance of three scenarios. The differentiation will be between currently implemented fixed-slope on-grid PV power plants in Kazakhstan and proxy similar solar parks using one- or two-axis solar tracking systems. This paper aims to determine to what extent the more effective, but more expensive tracking systems might be a suitable standard in future PV power stations in the country. For this purpose, the existent fixed-slope 50 MWp Burnoye-1 commercial solar power plant located in Jambyl region, Kazakhstan, is used as a benchmark. As expected, solar panels with tracking systems produce more electricity year-round compared to those with fixed slopes. In comparison, one- and two-axis tracking systems led almost to the same amount of electricity export to the grid. Furthermore, despite the proxy PV power stations with one- and two-axis tracking technology could reduce around 10 ktCO2e emissions per year. This 25 to 29% and 33 to 33% ratio of extra-cost to extra-energy production, respectively, made both tracking scenarios not economically competitive compared to fixed panels. Nevertheless, if a tracking system has to be considered to further reduce GHG emissions and add extra annual electricity generation using current installed capacity of Burnoye-I, our results demonstrated that one-axis tracking should be preferred above two-axis system.

description: The current economic climate and globalization requires a reduction in the “cost of operations”, the ability to “attract and retain key talent”, and a corporate culture that encourages innovation to maintain the competitive edge.   Research results indicate that a virtual work policy does help to achieve those goals through reduced turnover rates; and increased productivity and employee commitment (Grantham, Ware, Swanberg, et al, 2009, p. 9).  However, there are also negative aspects; such as when virtual workers are not included in decisions or in professional development opportunities.  That being said, will the corporation’s option for virtual work teams improve employee satisfaction; thereby, increasing retention and productivity?  From the business overhead viewpoint, is the option cost-efficient?

Purpose of the Evaluation

The overarching purpose of the Virtual Work Teams Program evaluation is to assess the value of the program to the company’s profit margin.

The specific purpose of the evaluation of the U.S. Customer Support Department Virtual Work Team Program is to determine business cost-efficiency, employee satisfaction, and productivity rates prior to offering the option to work virtually to all divisions of the organization, U.S.-based and abroad (Division of Cooperative Extension of the University of Wisconsin-Extension, 2014).

description: Because residential buildings consume significant reserves of energy, they are among the largest contributors to climate change. Carbon and greenhouse gas (GHG) emissions from buildings have negatively impacted the environment. In response, institutions around the globe have issued policies and regulations to minimize climate change problems, and while these policies have succeeded to some extent, additional factors are present that need greater attention. Among these additional factors are social inequality and environmental injustice in society, both of which must be analysed thoroughly before solutions can be suggested. This research work seeks to examine these factors and their effects; we analyse the factors that cause social inequality and injustice and we correlate those factors to the implementation of energy policies. We then pursue how these actions have consequences in civil society. Results show that some 15 social inequality factors are omnipresent, but the top three include: i) the limited participation of women in environmental campaigns, ii) variances in the adoption of building energy regulations across the globe, and iii) ethnic/racial discrimination with regard to how environmental safety is prioritized. We analyse these factors through the Fuzzy Analytical Hierarchy methodology, and our results are statistically validated through sensitivity analysis and a consistency check.

description: The study of higher-order and real topological states as well as the material realization have become a research forefront of topological condensed matter physics in recent years. Twisted bilayer graphene (tbG) is proved to have higher-order and real topology. However whether this conclusion can be extended to other two-dimensional twisted bilayer carbon materials and the mechanism behind it lack explorations. In this paper, we identify the twisted bilayer $α$-graphyne (tbGPY) at large twisting angle as a real Chern insulator (also known as Stiefel-Whitney insulator) and a second-order topological insulator. Our first-principles calculations suggest that the tbGPY at 21.78$^\circ$ is stable at 100 K with a larger bulk gap than the tbG. The non-trivial topological indicators, including the real Chern number and a fractional charge, and the localized in-gap corner states are demonstrated from first-principles and tight-binding calculations. Moreover, with $\mathcal C_{6z}$ symmetry, we prove the equivalence between the two indicators, and explain the existence of the corner states. To decipher the real and higher-order topology inherited from the Moiré heterostructure, we construct an effective four band tight-binding model capturing the topology and dispersion of the tbGPY at large twisting angle. A topological phase transition to a trivial insulator is demonstrated by breaking the $\mathcal C_{2y}$ symmetry of the effective model, which gives insights on the trivialization of the tbGPY as reducing the twisting angle to 9.43$^\circ$ suggested by our first-principles calculations.

description: Consistent quality oriented rate control in video coding has attracted much more attention. However, the existing efforts only focus on decreasing variations between every two adjacent frames, but neglect coding trade-off problem between intra and inter frames. In this paper, we deal with it from a new perspective, where intra frame quantization parameter (IQP) and rate control are optimized for balanced coding. First, due to the importance of intra frames, a new framework is proposed for consistent quality oriented IQP prediction, and then we remove unqualified IQP candidates using the proposed penalty term. Second, we extensively evaluate possible features, and select target bits per pixel for all remaining frames, average and standard variance of frame QPs, where equivalent acquisition methods for QP features are given. Third, predicted IQPs are clipped effectively according to bandwidth and previous information for better bit rate accuracy. Compared with High Efficiency Video Coding (HEVC) reference baseline, experiments demonstrate that our method reduces quality fluctuation greatly by 37.2% on frame-level standard variance of peak-signal-noise-ratio (PSNR) and 45.1% on that of structural similarity (SSIM). Moreover, it also can have satisfactory results on Rate-Distortion (R-D) performance, bit accuracy and buffer control.
