Team 1 designed a portable power system to provide electricity to areas in South Africa that experience frequent power outages. The system uses renewable energy sources like solar panels and wind turbines to charge batteries, which can then power homes and communities off the grid. Key challenges included keeping costs below $100 given poverty levels, using locally available materials, and creating a versatile design that works in various climate conditions and both with and without the main power grid. The team has so far corresponded with local experts, outlined project objectives, and made a preliminary website and poster. Next steps involve further collaborating with a South African university, refining customer needs, and developing a feasibility study.

Solar cell
This document discusses thin-film solar cells, which are made by depositing one or more thin layers of photovoltaic material onto a substrate using techniques like chemical vapor deposition. It was developed at MIT using this process to deposit materials onto flexible substrates like paper. Chemical vapor deposition is used to produce high-quality solid thin films and is commonly used in the semiconductor industry. Thin-film solar cells aim to reduce costs compared to conventional solar panels by using less material and creating lightweight, flexible designs.

It notes how the cold wind blows and scarlet leaves fall one by one, reflecting the soul. It expresses grief and separation as winter approaches, but also hope that new life will sprout again in spring.
English Empire 1
England had developed a more capitalist economic system compared to Spain, Portugal, and France by the 16th-17th centuries. This allowed the English merchant class to establish private ownership over land, labor, and capital to generate profits through trade. Emigration from England to the American colonies doubled during this time, with the colonial population in the Chesapeake growing significantly. The colonies shipped large amounts of tobacco to England, helping to open up a bigger market and contribute to cheaper tobacco prices. England established two types of colonial governments - royal colonies controlled by the crown and proprietary colonies belonging to private interests.

2009 Budget Explainer
The FOIFT operating balance sheet shows a balance of nearly $65,000 which is half of annual operating expenses. Income was less than budgeted in some categories but expenses for the conference were lower than expected. Despite only operating for 6 months, the budget is expected to be close to met. The value of endowments increased over $83,000 in the first 3 quarters of 2009 and is projected to exceed $800,000 by the end of the year. The difference between budgeted and actual incomes for 2008 and 2009 was almost identical when adjusting for one-time grants and expenses.

The UK established its first large-scale wave energy innovation programme in 1976 in a bid to develop an alternative domestic supply of energy in light of the oil crisis. As such wave energy became the principal focus for renewable energy public RD&D funding during the late 1970s. However, funding rapidly declined during the 1980s after the programme was discontinued due to a perceived lack of progress and a shift in political support towards nuclear energy. It wasn’t until the early 2000s that wave energy support enjoyed a renaissance with government believing it could play a central role in meeting its climate change and energy security targets, whilst also stimulating economic growth.
Whilst approximately £75m of public and £525m of private sector funds were subsequently invested in ocean energy RD&D between 2000 and 2012 this ultimately failed to deliver a commercially viable wave energy device. This slow progress can in part be attributed to the complexity of the engineering challenge this research explores whether the level and type of support on offer may have been a contributing factor. Drawing upon both qualitative and quantitative analysis this research examines the effectiveness of the UK’s wave energy innovation system and the lessons that have been learnt to help accelerate wave energy technology innovation in the future.
In terms of the level of funding the research finds that ocean energy has at a national and international level received less funding than other renewable energy technologies that have reached commercialisation. In terms of the effectiveness of the funding that was committed the research finds that the innovation support system put in place has exhibited a number of critical weaknesses. These include a pressure to go ‘too big too soon’, poor levels of developer collaboration, intermittent government support and a poorly coordinated funding landscape.
Despite these failures significant ‘policy learning’ has taken place in the UK, triggering a major reconfiguration of its ocean energy innovation system that is considered to have created a stronger innovation system. Positive developments include a refocusing on component vs. device development, treating wave and tidal energy innovation separately and a greater degree of innovation body coordination. Even so a number of recommendations are presented to strengthen the system further still, not least greater coordination between UK and Scottish governments and stronger links between universities and device developers.

This document discusses barriers to the widespread dissemination of solar water heaters (SWHs) in South Africa. It finds that while SWHs have significant potential to reduce electricity demand and greenhouse gas emissions, high upfront capital costs present a major barrier to adoption. Additionally, the current subsidy programs from the South African government may not be sufficient to facilitate widespread diffusion. Alternative financing mechanisms are needed to overcome barriers related to affordability and make SWHs a viable investment for more end users.

TNC 2014 nren climate change preparedness
Climate change preparedness plans are needed to adapt to a warming world with more severe weather. NRENs and higher education institutions should develop such plans aligned with national initiatives. Distance education is important for continuity during disasters. Preparedness plans involve risk analysis to identify vulnerable infrastructure and mitigation strategies. Reliability of the electrical grid is a major threat. Lessons from extreme weather show how distance education and robust networks are critical during disasters. Microgrids and renewable energy can increase reliability and lower costs and emissions.

Joint techs keynote january
This document discusses strategies for data-intensive science in a carbon constrained world due to climate change. It argues that while efforts to reduce emissions are no longer sufficient, data and computing will be critical to adapt to climate impacts. However, the growth of data and computing also contributes to emissions. The document examines how climate change will impact weather patterns, droughts, and energy systems. It also looks at how internet and research networks can help support science and education for adaptation, such as through brokered green clouds, software-defined networks, wireless networks, dynamic optical networks, and eScience platforms. The goal is to address data and collaboration needs while reducing emissions and adapting to climate disruptions.
20160615 EI Energy Systems final
This document discusses the challenges facing wave energy technology commercialization in the UK. It analyzes the UK's performance in wave energy innovation inputs like public funding and outputs like patents and deployments. Five issues are identified that contributed to wave energy's slow progress in the UK: overpromising results, a poorly coordinated innovation system, backing technologies that ultimately failed, bundling wave and tidal funding, and intermittent support. The document provides recommendations to address these issues like consistent funding, increased international collaboration, and strengthening links between developers and researchers.

Lost at sea? Charting wave energy’s difficult innovation journey towards comm...
The UK has a rich history of wave energy technology innovation stretching back to 1976 when it launched its first wave energy programme. Whilst funding was discontinued in the 1980s a new programme was established in the 2000s as wave energy was considered critical to meeting the government’s climate change, energy and economic objectives. Evens so the past 15 years have failed to deliver a commercially viable wave energy device. Consequently, this research examines whether the level and type of innovation support in the UK has contributed to this slow progress and whether these weaknesses could be addressed to help accelerate innovation in the future.
Drawing upon 32 interviews, alongside investment, publication and patent data analysis, this research examines:
1. how much investment has been committed to wave energy RD&D;
2. the mechanisms used to deliver this support;
3. the effectiveness of this support in fostering innovation and;
4. how this support could be re-configured to accelerate innovation.
The research finds that the UK has historically committed an above average level of ocean energy support versus other countries, seeing the UK lead in terms of patents, publications and deployment. However, the level of ocean energy funding still lags behind more mature renewable energy technologies (e.g. wind, solar PV) and its support has suffered from a number of weaknesses including a pressure to go ‘too big too soon’, little requirement for collaboration, intermittent support and a poorly coordinated and complex funding landscape.
Despite these failures significant ‘policy learning’ has taken place, triggering a major reconfiguration of UK wave energy innovation support such as a refocusing on component versus device development, treating wave and tidal energy innovation separately and greater coordination of innovation programmes. Outstanding policy recommendations include strengthening coordination between UK and Scottish governments and collaboration between universities and device developers.

Energy Low Emission Development Strategies: A Regional Overview of Latin Am...
Overall, Latin America and the Caribbean has traditionally been a world leader in the use of renewable energy sources for power generation (mainly hydro power), with important sub-regional differences, but the use of fossil fuels grew rapidly in the late 1900s.
There have been many initiatives on renewables and energy efficiency on the part of governments and local organizations, supported by multilateral development banks, UN organizations, international NGOs.
The recent development of non-traditional renewable energies (wind, solar, geothermal, modern biomass) is helping meet important development goals (growth, access, affordability) with a lower impact on greenhouse gas emissions.
There are still important challenges related to investment climate and business model financing, but there are many lessons to share, both on what works and what doesn´t work.
A final submision by todd vatalaro
This document contains a research proposal that aims to compare the effectiveness of distance education versus traditional education. The proposal includes an introduction that provides background on the rise of distance/web-based learning and how it has evolved from correspondence courses to utilize modern Internet technologies. The proposed study would investigate whether web-based learning is as effective as traditional classroom learning by having 100 female students aged 18-25 take the same course, with 50 in the traditional classroom and 50 online, and then comparing their test scores. The proposal outlines the problem statement, research objectives, methodology, and resources needed to conduct the study over one academic semester.

The document discusses using emotion as a reward signal in reinforcement learning. It proposes that appraisals of situations can generate emotions, and that emotions can then drive reinforcement learning. The model was implemented in the Soar cognitive architecture. Results showed that using emotion allowed the agent to learn tasks faster compared to standard reinforcement learning, and that incorporating mood led to even faster learning with less variability in performance. In the future, the researchers aim to explore more complex multi-agent scenarios using this approach.

While our application's case study involves a drug search, the techniques and principles shared in this session can be adapted to improve search functionality in a wide range of applications. Join us to learn how PostgreSQL and Azure AI can be harnessed to enhance your application's search capability.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

Mutation Testing for Task-Oriented Chatbots
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.
