It describes how Green Power Labs developed software to process images from geostationary satellites like GOES into high resolution solar radiation maps for Atlantic Canada. The maps were groundtruthed against meteorological station data with a correlation of 0.94. The software tools allow automated processing of satellite images within a GIS and have applications for solar system monitoring and forecasting to support energy management and production.
2012 Reenergize the Americas 1B: Craig MataczynskiReenergize
This document discusses the nexus between energy, water, and economic growth from 1950 to 2008. It shows that as GDP grew by an average of 2.8% annually from 1970 to 2008, energy use grew by 0.9% and water use grew by 0.3%. The document also provides data on the water usage of various energy production methods, showing that coal and ethanol production require more water than other sources. It advocates combining desalination with energy production to maximize the water-energy nexus.
The document shows median year structures were built for various geographies in Hawaii according to the 2009 American Community Survey and 2000 Census. In general, median years are later for the 2009 data compared to 2000, with Honolulu County having the earliest median year of 1973. Specific places listed range from 1950 for Wheeler Air Force Base to 2000 for Puako.
The document discusses the problem of global warming caused by increasing levels of carbon dioxide (CO2) in the atmosphere from the burning of fossil fuels. It explains that CO2 interferes with the Earth's natural cooling system by trapping infrared radiation, leading the planet to continue warming even if emissions levels stabilize. The only way to stop global warming is to cap CO2 levels by transitioning from fossil fuels to clean energy technologies. The presentation provides examples of policy steps and individual actions that can help adopt clean energy solutions and halt the dangerous impacts of climate change.
This document summarizes spatial analysis of tornado and hail reports in the lower 48 United States from 1957-2006. It analyzes tornado and hail frequency data from the National Climatic Data Center to create maps showing the average occurrences of tornadoes and hail per 100 square miles. The analysis uses a grid cell approach, averaging cell values with neighboring cells and smoothing transitions to account for randomness in reported event locations. Tornado and hail activity is highest in the central plains from March through June.

Between 1892 and 1997, a total of 2.1 million people were deported from the United States. A change in laws in 1996 permitted the number of deportees to increase from 70,000 in 1996 to 114,000 in 1997. In 1998, the number of deportees rose to 173,000. The numbers stayed fairly steady until 2003, when the creation of the Department of Homeland Security (DHS) infused more money into immigration law enforcement and 211,000 people were deported. From there the numbers have continued to rise – peaking at just over 400,000 in 2012. These numbers are unprecedented: by 2014 President Obama will have deported over 2 million people - more in six years than all people deported before 1997. However, there is more to this trend than these numbers. The content of policies has also changed. There have been relatively low numbers of returns as compared to removals, a reflection of a focus on interior enforcement. There has been a shift towards the deportation of convicted criminals. With these trends, unprecedented numbers of people have been separated from their families in the United States. Obama has not only deported more people than any President; he also has separated more families by focusing on interior enforcement.

1) Agricultural risks in Sub-Saharan Africa are linked to low soil fertility, unpredictable water availability due to climate, and low use of soil amendments and other inputs.
2) These risks have contributed to low and unstable crop yields, increasing poverty and hunger in the region.
3) Risk mitigation strategies are needed to address soil fertility depletion and make better use of water resources through improved farming practices and investment in soil health and water management.
André Bationo - Agricultural risks linked to soil, water and climate in Sub-S...Global Risk Forum GRFDavos
Agricultural risks in Sub-Saharan Africa are linked to soil, water, and climate. Risks stem from inherently low soil fertility and low use of inputs like fertilizers. Water and climate risks include high rainfall variability, recurrent droughts and floods, which reduce agricultural productivity and economic growth. Efforts to mitigate risks include soil and water conservation techniques, use of organic and mineral fertilizers, development and dissemination of improved seeds, and other sustainable land management practices. However, widespread adoption of risk-reducing technologies remains low.
Pakistan's economy has experienced slowing growth over the long run due to a lack of structural reforms and incentives for sustained investment. While remittances and debt inflows have contributed to meeting external financing needs, they have also contributed to "Dutch disease" effects. Going forward, Pakistan will need to implement structural reforms in key sectors like energy and taxation to improve its fiscal position and reliance on external financing. Engaging the Pakistani diaspora through knowledge transfer and targeted investment in high-multiplier sectors could help counter Dutch disease effects from remittances and promote more sustainable development.
What is Just: Education, Excellence and Equity Laurie Posner
This document discusses issues of equity and justice in education. It summarizes data showing growing income inequality in the United States and how this impacts education opportunities and outcomes. Families with higher incomes spend more on enriching their children's education and children from higher income families are more likely to complete college. It also notes that in Texas, schools with more economically disadvantaged students receive less funding per pupil and have less access to qualified teachers. Stories from parents and educators in Texas discuss how budget cuts are negatively impacting students and schools. The document argues that the quality of education a child receives should not be determined by their zip code or family income.

The document will cover climate impacts on Egyptian agriculture, vulnerability assessments, and priorities for agricultural adaptation plans in Egypt.
This document discusses trends in the US economy and agriculture from 1947 to 2006. It shows that while agriculture GDP has increased from $19.9B to $129.7B over this period, its percentage of total US GDP has declined from 6.8% to 1%. It also shows graphs depicting the rise of other industries like finance and services as a percentage of GDP, and increased agricultural productivity through higher output with fewer inputs over time.
2 user financing of rural handpump water services presentationIRC
This document discusses user financing of rural handpump water services. It provides statistics showing that only 63% of handpumps are functional, reducing coverage by one third. Functionality declines over time, with pumps from the 1970s having much lower rates than newer pumps. The document outlines a typical handpump maintenance model where 50 user households each pay $2.40 annually, with 10% exempt. It notes annual life-cycle costs are around $235. The spiral of unsustainable dependence is described where inadequate tariffs lead to inability to pay for repairs, resulting in long downtimes. Additional challenges are also listed.

The goal is to visualize the relationship between landscape features, water levels, and potential flooding risk.
This document discusses the selection of pipe materials for water distribution networks. It outlines a methodology for comparing ductile cast iron (DCI) pipes and polyethylene (PE) pipes based on quantitative and qualitative parameters. Quantitative parameters like initial investment costs and whole-life costs are analyzed. Qualitative parameters like environmental impact, corrosion resistance, durability, and operational experience are also evaluated and rated for each material. The methodology is intended to help objectively evaluate pipe materials for specific network applications and diameters. While PE is generally better for smaller diameters and DCI for larger, each project requires analyzing multiple factors to determine the optimal material.
This document describes a risk assessment methodology for hydraulic overloading of urban drainage networks using fuzzy set theory. It presents a case study of a town in Bulgaria with a combined sewer system and reports on hydraulic modeling conducted. The modeling found some design issues but no surface flooding. The methodology defines membership functions to assess reliability and risk based on the response of the system to external loads from rainfall events of varying return periods. Maps can show the spatial distribution of reliability across the urban area before and after reconstruction. The methodology is proposed as an appropriate approach to adequately assess risk of overloading through simulations at different rainfall intensities.

HOBAS is a company with over 5 decades of experience producing GRP (glass fiber reinforced plastics) pipes. They employ over 1,000 people and generate over 210 million Euros in annual revenue. HOBAS produces GRP pipes using two main methods - centrifugal casting and filament winding. Their pipes are used in applications like sewage, drinking water, irrigation, and more. HOBAS pipes have a high safety and reliability due to their comprehensive design, durability, and leak-free joint systems.
Jaroslav Pollert of the Czech Technical University developed a new type of combined sewer overflow (CSO) called the TOK to address environmental pollution from CSOs and comply with European directives. The TOK has a simple design with an accumulation chamber and adjustable overflow slit that can be easily installed and operated at a low cost. Mathematical and physical models were developed and compared to optimize the shape of the overflow slit to minimize suspended solids in the overflow. Initial TOK installations were successful and more are planned, with the potential for further design improvements ongoing.
Regional Master Plans for Water Supply and Waste Water were outlined for 51 designated territories in Bulgaria. The plans require analysis of existing infrastructure and future projections to develop short, medium, and long-term investment programs. Stakeholders like the River Basin Directorate and Water Supply and Sewerage Operators must approve the plans according to Bulgarian law and EU directives. The plans seek to improve water and wastewater infrastructure and comply with the EU Water Framework Directive through developing a GIS database of facilities and identifying new projects.
- Bulgaria relies on surface water, underground water, and reservoirs for its potable water supply. Surface water makes up 82% of resources, with underground water being the only solution for many regions.
- Between 1991-2010, Bulgaria's water availability index (WAI) remained above 2000 m3/capita/year, indicating no water stress, while its water stress index (WSI) remained below 0.15, also indicating no water stress.
- As of 2010, over 5031 settlements were served by Bulgaria's national water supply system, providing potable water to 98.8% of the population at a rate of 340 liters/capita/day. However, only 40% of supplied

1-3_3. impact of pharmaceuticals and personal care products, maja sremackiYWPBulgaria
This document summarizes a presentation on the impact of pharmaceuticals and personal care products (PPCPs) on wastewater treatment in developing countries. It discusses PPCPs as emerging contaminants, characteristics and introduction pathways into the environment. Specific PPCPs like ciprofloxacin and ibuprofen are examined. The document also reviews how PPCPs may impact wastewater treatment processes and techniques for their elimination. Plans for future activities and research on PPCPs in Serbia are presented, including monitoring, legislation, and studies of targeted PPCPs in wastewater, groundwater, and surface water.
The document summarizes research from a project in the Czech Republic studying the removal of selected pharmaceuticals and personal care products (PPCP) at wastewater treatment plants (WWTPs). Monitoring of 4 WWTPs found varying removal rates, with ibuprofen and salicylic acid showing up to 99% removal, while diclofenac and carbamazepine were more resistant to treatment. The next phase will test tertiary treatments like ozonization and activated carbon to improve PPCP removal.
The document summarizes the state of wastewater treatment technologies. It discusses best available technologies (BAT) as those proven effective and efficient. The core BATs are intensive and extensive biological treatment technologies. Intensive technologies use suspended biomass in activated sludge or attached biomass in trickling filters. Extensive technologies include constructed wetlands, lagoons, and biological lakes. Driving forces for development include legislation, climate change, water scarcity, and energy efficiency goals. While wastewater has some energy potential, it represents a small fraction of typical plant or household energy usage.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
