Security Information and Event Management (SIEM) systems are a fundamental component of the ubiquitous ICT infrastructures that form the backbone of our digital society. These systems are mostly used to monitor infrastructures using many types of sensors and tools and correlate the obtained events to discover possible threats (attacks, vulnerabilities, etc.) to the organization. The DiSIEM project aims to enhance existing SIEM systems with diversity-related technology. More specifically, we want to (1) enhance the quality of events collected using a diverse set of sensors and novel anomaly detectors, (2) add support for collecting infrastructure-related information from open-source intelligence data available on diverse sources from the internet, (3) create new ways for visualising the information collected in the SIEM and provide high-level security metrics and models for improving security-related decision project, and (4) allow the use of multiple storage clouds for secure long-term archival of the raw events feed to the SIEM. Given the high costs of deployment of SIEM infrastructures, all these enhancements will be developed in a SIEM-independent way, as extensions to currently available systems, and will be validated through the deployed in three large-scale production environments.

The minimum phase-to-ground fault current required to be sensed by protection systems in medium-voltage (MV) networks can be as low as 0.7 A in a few countries, leading to a lot of undesired relay trips and poor service quality to costumers. However, these settings raise the protection threshold above the minimum fault current that concerns network operators regarding human safety, although they cannot be practiced when grounding is distributed. The purpose of this paper is to present a risk assessment foundation to determine the required protection sensitivity to ensure human safety in MV distribution networks. The proposed approach is based on a biophysical model included in IEC standards, the consideration of current paths models for typical faults and Monte Carlo methods to deal with nonlinearity, and the many involved random variables. Downed conductors and line-to-concrete pole faults are investigated and sensitivity analysis performed to highlight some important determinants of the results. © 2010 IEEE.

Insulating oil plays a fundamental role in power transformers, providing both the electrical insulation and the means for transferring the thermal losses to the cooling system. In addition, insulating oil is an important information carrier. It can provide information about the degradation of insulating paper, by depolymerization, which is very important in transformer diagnostics . © 2006 IEEE.

A power purchase agreement (PPA) is a contractual mechanism used by energy suppliers and consumers to manage long term price and volume risk. The contract has value once an agreement on price and volume has been made. The value of the contact is stochastic and based on the current and future expectations of the underlying electricity price. The total contract value can be positive for the producer if realized market prices are lower than originally expected or positive for the purchaser if prices are higher than expected. These contracts typically are uncollateralized and therefore pose a credit risk to both counterparties. Assessing the value of this credit risk can be slow and computationally burdensome requiring Monte Carlo calculations, so this paper proposes an approximation to the problem that yields a closed form solution. © 2015 IEEE.

The presence of potentially corrosive sulfur species in insulating oil has caused a significant number of catastrophic failures, which have been reported over the last few years. However, the sources of corrosive sulfur in oil have not yet been completely identified. Corrosive sulfur species can be residuals of the refining process, but mainly they are formed under normal operating conditions. It has been shown that noncorrosive sulfur can become corrosive after being exposed to, for example, elevated temperature, electrical stress, and hot metal surfaces, producing metal sulfides , . © 2006 IEEE.

Transformers are essential components of electric power generation, transmission, and distribution, and the majority of power transformers rely on liquid dielectrics as an insulating medium and for heat transfer. At present, the most common liquid dielectrics used are the mineral oils, which are produced from the middle range of petroleum-derived distillates. In recent years, concerns have been expressed regarding the presence of polynuclear aromatic hydrocarbons in mineral oils, because in the event of a transformer fire, or explosion, polynuclear aromatic hydrocarbons could readily be released into the environment. This situation has put mineral-oil-filled transformers in sensitive areas, such as inside buildings, in residential areas, and near schools or hospitals, under scrutiny. Human health and environmental concerns have led to efforts to develop alternative transformer insulating oils for use in these sensitive areas. In particular, vegetable oils have drawn the most attention, and research on the properties and performance of vegetable oils has been carried out in a few laboratories . © 2010 IEEE.

EDP Software simplifies the enormous complexity of workforce scheduling to a one-button solution, leading to leaner staff scheduling while reducing overtime, ensuring coverage, and managing fatigue. For EDP Software clients such as Ford, Shell, and the Province of Quebec, ‘complex’ is not hyperbole when it comes to workforce management. Union agreements, state, federal and industry regulations, and best practices in fatigue and performance may all need to be accounted for in these industries in which regulatory compliance is necessary and the stakes are high where safety is concerned. EDP Software CEO Sachin Agrawal claims that many scheduling software vendors provide standard solutions, but they are not customized to the needs and regulations of specific companies and industries. This is especially true for regulations at a local level in the nuclear, automotive, manufacturing, corrections, health care, and petrochemical industries. SchedulePro is EDP Software’s SAAS solution to complex, idiosyncratic scheduling needs. It offers customization, employee self-serve, and compliance features, and automatically generates schedules based on a company’s rules. The software’s dashboard reveals rule violations in real-time, and a user is able to produce instant audit reports as needed. Speaking of the services that exist in the market as a whole, Agrawal said, “The biggest difference is our intelligence in understanding the way our customers actually do business. We have the capability so that even though everyone has a different set of rules, we have one common engine that is able to optimize your resources, all while maintaining compliance with the strictest of regulations.” Agrawal continued, “We’re able to optimize and reduce costs, follow unique business workflows , and automate it so you’re in compliance right now with one button.” The company started as a consulting firm performing custom development for government clients, with an early version of SchedulePro being a side project. The 2008 economic downturn, however, spurred a reset for the company and a re-evaluation of its core value proposition, as clients’ slashed consulting budgets, thereby shrinking the consulting services arm at the software company. Agrawal said, “In 2008, we thought, ‘What are we now?’ We were no longer a consulting company, but we had this scheduling software and this know-how. We thought, ‘Let’s repackage this for the web’. Everybody wants web-based services. At that time, all the big players hadn’t converted their services to the web yet.” “We’ve been steadily growing since then, and have been able to sign up some big marquee clients. Because we have such differentiated value in this scheduling space, we’ve been able to win these big clients. We’re the company that comes in and solves those problems after the establishment either gives up or fails to deliver.” The upside of the 2008 downturn was that it provided the impetus for companies to examine how they deployed resources and where they could save on expenses. With that motivation, along with the proliferation of cloud-based services, companies began to search for vendors instead of maintaining expensive in-house IT departments devoted to this kind of software. Agrawal said, “Companies in the automotive sector, for instance, know how to build great cars. They know how to engineer automobiles. They’re not experts at software. They just want a solution, and it’s much cheaper to purchase a solution than to build and maintain that expertise in house. We’ve been able to take several people managing an in-house program and turn it into just one IT manager, who really is just managing a relationship.” Compounding the need, older workforce management tools designed in-house a decade or more ago may be becoming obsolete or increasingly burdensome to update. This has presented an opportunity for growth for EDP. Agrawal said, “Legacy tools built in-house need to be replaced, and so these companies don’t need a team of IT professionals when the company’s core competency is, for example, manufacturing. The downturn precipitated the kind of spend to get rid of these resources internally. People realize it’s expensive to build their own software.” This simplification and reliability is a huge benefit to industries for which compliance is becoming more complex, especially in the aftermath of large-scale accidents with fatal or disastrous consequences. Agrawal said, “In the oil and gas field, there’s ever-increasing knowledge of fatigue management and rules. New management is coming into play, and these new regulations are causing the impetus to deal with these. So their compliance and regulatory burden is increasing.” EDP has partnered with Vancouver company Fatigue Science, bringing an additional safety aspect to their business. Fatigue Science, pioneers in commercial fatigue and performance consulting, “quantifies the source and extent of fatigue in the workplace and helps mitigate risk related to that fatigue.” They have worked on peak performance with the Seattle Seahawks, Dallas Mavericks and Vancouver Canucks. RELATED: How One Canadian Startup is Making Sleep the Next Big Thing in Professional Sports “Once you start really understanding the body, the biometrics, and the deep research that these tools are based on, you may think, ‘I’m in compliance with these rules, but now I’m really going to reduce my risk, really understand how I can schedule my staff in the most effective way, based on science,” said Agrawal. EDP Software has recently been accepted into the inaugural cohort of BCTIAs Hypergrowth program, a second-stage accelerator aiming to rapidly ramp up earnings for companies that have already achieved product-market fit and revenue. For the near term, the team at EDP wants to continue its growth in industrial fields and key markets where they can help with complex scheduling and compliance burdens. In the long run, they see a huge potential in the workforce management space. Other vendors, Agrawal claims, do not focus on workforce management in and of itself, but instead only address it as a way of getting business in HR and payroll processing. Agrawal said, “None of these companies going after payroll are thinking, let me understand in depth the way petrochemical works or automotive works, and the types of interactions among people, process, machinery, and inventory. We look at how all of these things are interacting, and build a solution that really helps these companies optimize talent, workforce, and cost so they can not only reduce their payroll costs, but increase efficiency, increase quality, increase delivery, and increase safety. We want to make manufacturing more effective, more efficient, and safer.” “The needs of large organizations are changing. They don’t just want a tool that works. They want a tool that can provide deep business value, and so there’s a huge opportunity,” Agrawal said. “There’s a huge opportunity for us to disrupt the establishment, provide a lot more value to our customers, and really change the expectations that people have of B2B software. It seems wide open to us.”

Scott Walker’s up-and-down campaign for the Republican presidential nod has produced at least one constant: As far as wind and solar developers are concerned, the Wisconsin governor may be the worst man for the job. Five years after Walker took office, renewable energy in Wisconsin is lagging the boom in the rest of the country and industry blames the two-term governor for the shortfall. Walker and his appointees have pushed new restrictions on windmills, cut tax incentives and research funding and last year imposed the nation’s highest fees on rooftop solar owners. Wind and solar advocates hope to make Walker pay, painting him as an enemy of consumers who want to break away from big utilities. Most Republicans on the 2016 trail talk of ending subsidies and regulations favoring renewables, tying them to President Barack Obama's environmental agenda. Walker’s worked hard to make that a reality on the ground, said Amy Heart, a spokeswoman for the industry-backed Alliance for Solar Choice. “It’s pretty clear that Republican primary voters won’t support Governor Walker,” Heart said in a telephone interview. “They’re not going to support a politician who supports state-sponsored monopolies who are killing competition.” The alliance represents companies including SunRun Inc. and SolarCity Corp., the biggest rooftop solar installer in the U.S. It’s suing Wisconsin over the new fees, which Heart blames for “the worst” environment in the nation for home solar owners. It’s another potential headache for a campaign that has suddenly hit rough waters. Leading polls of Iowa caucus voters for much of the year, Walker, like the rest of the Republican field, has been lapped by Donald Trump. The Wisconsin governor fell to third (tied with Texas Senator Ted Cruz) in the most recent Bloomberg Politics/Des Moines Register Iowa Poll, backed by 8 percent of likely caucus-goers. Trump led with 23 percent, followed by retired neurosurgeon Ben Carson at 18 percent. In a statement, the governor’s office said focusing on wind and solar misses the "full picture” of what Walker's done to support renewables. The administration has backed tax breaks and loans for biodigesters that create power from farm waste as well as small-scale generators that let diesel trucks reduce idling, the e-mailed statement said. The state surpassed its goal of producing 10 percent of electricity from renewable sources in 2013—two years ahead of schedule. “Renewable energy isn't only confined to wind and solar,” Laurel Patrick, a spokeswoman, said in a statement. “Governor Walker wants residents and businesses to have as many options as possible when it comes to energy resources.” Walker, at an Iowa candidates’ forum in March, said he supported an “all of the above” energy policy that didn’t favor any particular source. The country needs as many different “energy options as possible out there and if I was in a position as president I’d advocate for that.” Still, while wind and solar installations have surged around the U.S., growth in Wisconsin has slowed down under Walker. The state hasn’t added any new wind capacity since 2011, according to the Washington-based American Wind Energy Association. And no Midwestern state has added fewer megawatts of solar in that time, says the Solar Energy Industries Association, another Washington group. “The last five years here have been tough on renewables and it really started when the governor came in,” said Tyler Huebner, executive director at Renew Wisconsin, an advocacy group whose members include Portugal-based EDP Renewables and Photovoltaic Systems LLC of Amherst, Wisconsin. Exhibit A among Walker critics is the monthly charge on solar owners approved in December by the state Public Service Commission. The fee adds as much as $30 a month for the typical solar customer within the boundaries of the state’s largest utility, Milwaukee-based We Energies Corp., Huebner said. We Energies said solar users still rely on the company’s electric grid and should pay their share to maintain it. It’s an argument made by utilities around the U.S. in recent years. While regulators elsewhere have mainly rejected or scaled back such requests, the Wisconsin commission approved. The measure passed 2-1, with two Walker appointees voting in favor. The fees help make Wisconsin “an outlier” when it comes to support for solar around the U.S., said Ben Inskeep, an analyst at North Carolina State University’s Clean Energy Technology Center. “Among all the cases we’ve seen in the country, this is probably one of the top ones in terms of reducing the value proposition for residential customers.” Walker’s rocky relationship with the industry goes back even farther. Within weeks of taking office, he endorsed a bill in 2011 to expand the buffer area required around new wind turbines. The legislation was supported by realtors who said the turbines hurt neighbors’ property values. While the measure never passed, the uncertain regulatory climate has virtually shut down new wind development in the state, according to Huebner. The state has made life harder in other ways, industry says. Wisconsin officials have refused to clarify rules on whether solar companies can lease their panels to homeowners, keeping out national players like SolarCity and SunRun, according to Heart, of the Alliance for Solar Choice. They’ve also resisted increasing Wisconsin’s renewable power requirement, which trails that of neighboring states. In February, Walker moved to eliminate $8 million in funding for the Wisconsin Energy Institute, part of a package of $250 million in cuts to the state university system. “If you add up all the steps and all the signals coming out of the current administration, it’s not welcoming, that’s for sure,” said Gary Radloff, a policy analyst at the institute, which conducts research with private sector energy companies. Wisconsin’s become “an island of renewable-energy stagnation amid a sea of growth.” Critics look at Walker’s record and see the ideological imprint of Charles and David Koch, the billionaire Republican campaign donors. The Koch-backed Americans for Prosperity provided funding and volunteers during Walker’s rise to power in Wisconsin. That group, and another partly funded by the Kochs named the American Legislative Exchange Council, have championed efforts around the U.S. to roll back state incentives for renewable power, calling them a distortion of the free market. Patrick, the governor’s spokeswoman, didn’t respond to questions about the new solar fee or wind-siting rules. The state provided $900,000 in seed money last year for a private energy-research center in Milwaukee, she said. It’s also provided more than $16 million in revolving loans for energy efficiency and renewables projects, according to her statement. Whether Walker’s energy record affects the presidential campaign is anybody’s guess. Most Republican candidates say they oppose clean-energy subsidies like the federal tax credit for wind power, arguing the industry should stand on its own. Walker, like the rest of the field, has also blasted President Obama’s new climate-change regulations, which are expected to boost renewables over coal-fired power plants. The rules would be “a buzzsaw to the nation’s economy,” Walker said during an Aug. 3 campaign stop in New Hampshire. “I want to balance a sustainable environment with a sustainable economy.” CORRECTION: This article was updated to correct the role of the American Legislative Exchange Council in the debate over renewable energy in the U.S.
