Spacecraft charging related risk of floating connector pins

first_imgEvery national spacecraft charging related design guideline or design standard includes prohibitions against floating, or ungrounded, connector pins. The rationale is obvious. A floating connector pin represents ungrounded metal with a propensity to accumulate charge from the space plasma environment and, upon breakdown, effectively couple the discharge energy directly into sensitive system electronics by virtue of adjacent pins and cables. Satellite designers may recognize that, seemingly as common as the rationale is obvious, there are instances in violation of this clear guideline and impassioned arguments for permissions to do so. This paper represents a comprehensive effort to quantitatively, theoretically, analytically, and empirically assess the risk associated with ungrounded connector pins in the selected (geostationary earth orbit and medium earth orbit) orbits.last_img read more

Jen Giattino is the mayor Hoboken deserves

first_imgDear friends and neighborsI am proud to endorse City Council President Jen Giattino to be our next Mayor of Hoboken and her council slate comprising of Zoning Board Chair Jim Aibel and long-time Hoboken residents Jason Ellis and Sal Starace.The day Mayor Zimmer announced her intentions, I awoke feeling unsettled and concerned about Hoboken’s future. To me the right message going forward for Hoboken is embracing what works, but fixing what doesn’t. And when Jen decided to run for mayor a week later, the unsettled feeling went away.Being the mayor of Hoboken is an executive role, not a legislative one, which is critical as you think about the candidate’s ability to execute on their vision. Our next mayor needs to have demonstrated: – Experience protecting the quality of life for Hoboken residents;– Ability to lead and navigate through many prioritizes – big and small – and get things done;– Willingness to challenge the status quo;– Financial focus to be a steward for taxpayers; and– Commitment to working with others to ensure the best outcome for Hoboken.Jen is the only candidate who has all of these. Jen offers her hand and heart to anyone who needs it. She walks our streets daily and helps her constituents on everyday life issues like dirty streets and parks and unsafe intersections and helps those being displaced from their homes. Her neighbors tell me the following about her: “Jen is everyone’s neighbor”, “Accessible and acts”, “Mom who gets s–t done”, “Helped me when…”, “She is all about Hoboken”.Jen has been my partner on the many issues that required a deeper understanding and financial review – like the 30 year PILOT given to the developer of the ginormous “7th and Jackson” project – Jen and I were the only two dissenting votes. She shares my view that improper development is the biggest threat to our community. That getting development right for Hoboken requires better financial review to level the playing field in negotiations with developers. And that prioritizing commercial development is critical to curb overcrowding impacts residential development has on traffic, parking and schools and bring much needed commerce and tax revenue to our community.In this election, we cannot go backward to the corrupt practices of our past that sent two of our prior three mayors to jail. Jen and her entire team are simply on the right side of wrong. I cannot stress enough the importance of supporting a candidate like Jen who is not beholden to any special interests (like developers) and who is not supported by votes that will be paid for.Jen is what Hoboken deserves. Someone who is all about Hoboken and not using this as a stepping stone to higher office. Someone who puts our residents first, solves the little things that seem big to individuals and can also tackle the big things that will have everyday impact to everyone in Hoboken. Please join me in voting for Jen and Team Giattino on November 7th.Tiffanie FisherHoboken City Council, 2nd Wardlast_img read more

Redundancies as Fords goes into liquidation

first_imgFords Bakery in Prestonpans has been placed into liquidation, with 35 staff made redundant, and around 25 set to move to its parent company.The bakery had gone into administration last summer and was sold to Scullions Wholesale Bakery, a subsidiary of the McGhee Group, in the hope that it could reverse the bakery’s trading losses and make it profitable, liquidator Tom Hughes, partner at Gerber Landa & Gee chartered accountants told British Baker. “However, as the year went on, that became very difficult. Cut-backs to staff were made to try and address the issue, but it was still making serious losses, so there was no alternative but to close the business,” he said. The firm was placed into liquidation on Sunday 20 March, with the liquidator looking to make an asset sale only. A spokesperson for Scullions said:  “Despite considerable efforts, the business continued to show trading losses. It was therefore concluded that the current operation was no longer viable. “While this will result in a number of job losses, around 25 positions will be saved, with those personnel redeployed within the restructured Fords Bakery business, as part of the McGhee’s Bakery Group.”Hughes confirmed that investigations were being made into any monies owed to creditors, with a creditors meeting scheduled for next Friday (1 April).>>Scullions comes to rescue for Fordslast_img read more

Gay cake row decision due

first_imgThe verdict on the gay cake row is expected to be announced on 7 May, the same day as the UK election.The case disputes the decision of Ashers Bakery to turn down an order for a cake with an image of Sesame Street puppets Bert and Ernie below the motto Support Gay Marriage. According to the Belfast Telegraph, Judge Brownlie said: “It is not a straightforward area of the law.“Obviously this is a case in which I propose to reserve my judgement.”The Equality Commission, which champions complaints of those who claim to have been discriminated against on the grounds of their religion, race, age, gender or sexuality, is seeking damages against Ashers.It said that if the bakery was allowed to refuse to do business with a minority group, a precedent would be set for discrimination.Christian charity the Christian Institute is backing Ashers in the case, which it said proved the need for the law to reasonably accommodate family-run businesses with firmly held beliefs.The cake, ordered to celebrate International Day against Homophobia and Transphobia on17 May 2014, was supplied by another bakery.last_img read more

Developer Invenergy proposes large solar-plus-storage project in Wisconsin

first_img FacebookTwitterLinkedInEmailPrint分享Wisconsin State Journal:The developer of a proposed solar farm in Iowa County is planning a second solar farm in Kenosha County that could feature the first utility-scale battery storage in Wisconsin. Chicago-based Invenergy last week submitted an engineering plan for a 200-megawatt solar farm with a 50-megawatt battery component.That’s larger than any battery currently deployed on the nation’s power grid and the first in the state of Wisconsin, according to data from the U.S. Energy Information Administration. Invenergy has installed 31.5-megawatt batteries in Illinois and West Virginia, which account for most of the capacity in the company’s advanced storage portfolio.Batteries enable renewable energy sources like wind and solar to deliver power on demand, similar to traditional fossil fuel generators. They can also contribute to grid stability and provide reserve capacity to meet peaks in demand.“With batteries, it can compete in the marketplace in multiple ways,” said Andy Olsen, a senior policy advocate with the Environmental Law & Policy Center in Madison. “Not only on the power but when we get the power, which matters quite a bit.”Invenergy says it plans to submit a permit application to the Public Service Commission in April. Company spokeswoman Beth Conley said the Paris solar farm is being proposed as a developer-owned project but the company is in talks with potential utility buyers.As of December, there were 119 utility-scale batteries with a combined capacity of 845 megawatts deployed nationwide, according to the EIA. Only two dozen of those are larger than 10 megawatts.More: Proposed Kenosha County solar farm could feature Wisconsin’s first utility-scale battery Developer Invenergy proposes large solar-plus-storage project in Wisconsinlast_img read more

Coal bearing the brunt of global decline in electricity demand

first_imgCoal bearing the brunt of global decline in electricity demand FacebookTwitterLinkedInEmailPrint分享Bloomberg:As silent factories and deserted offices hobble demand for electricity worldwide, the biggest loser is coal.In the U.S., coal’s share of power generation has dropped more than 5 percentage points since February on the nation’s biggest grid while output from natural gas plants and wind farms held steady. In Europe, it’s down 2 points. Even in China and India, where coal still dominates, it’s losing market share during the pandemic.It comes down to cost. Coal power is more expensive than gas and renewables in many places and, hence, is the first fuel priced out of the market when demand falls. Its plunging use amid the lockdowns is a boon for efforts to fight climate change, hastening a shift that was already underway to weed out the dirtiest fossil fuel.In the U.S., coal is now supplying just 14% of power on the grid serving 65 million people from Illinois to New Jersey. That’s down from almost 20% in February, according to a Bloomberg analysis of data from the grid operator, PJM Interconnection LLC. It’s the only major fuel to slump.In Europe, coal’s share of power generation has dipped to 12%, from 14% a year ago, according to data from Wartsila Oyj, the Finnish energy technology company. The decline is particularly sharp in Germany, where electricity from hard coal and lignite, sometimes called brown coal, plunged to 18% of net generation in the first two weeks April. One year ago, they accounted for 35%.In India, coal’s share of the power mix slipped to 65% from 71% in the month since Prime Minister Narendra Modi announced lockdowns to contain the outbreak. The country’s coal imports for power plants in March fell 28% from a year earlier. The share from renewables, nuclear and hydropower rose. And in China, thermal power output, which is mostly from coal, slumped 8.2% in the first quarter while solar and wind gained.[Will Wade, Chris Martin and Mathew Carr]More: In global electricity slump, coal is the big loserlast_img read more

Colombia: Multinational operation seizes 2.7 tons of cocaine

first_img BOGOTÁ, Colombia – Three Colombians and two Hondurans were arrested aboard an unflagged vessel suspected of transporting 2.7 tons of cocaine near the Colombian island of San Andrés, officials said. The arrests and seizure, which were carried out during Operation Daga, were the result of a joint effort among the coast guards of Colombia, the United States, France, Honduras and Nicaragua, according to the website El Since the five detainees were intercepted by French authorities aboard an unflagged vessel in international waters, they were subsequently taken, along with the drugs, to the French island of Martinique and handed over to local authorities, according to La Mexico: Drug war has displaced 230,000 Dominican Republic: Alleged drug smuggler extradited to U.S. By Dialogo March 31, 2011 Bolivia: Cocaine seized near border with Peru MEXICO CITY – The country’s fight against narcotics has displaced about 230,000 people, with about 50% of them seeking refuge in the United States, according to the Internal Displacement Monitoring Centre. The institution’s report was based on studies by Mexican researchers, as the Mexican government doesn’t maintain official figures related to the displacement of its people. “Independent surveys put their number at around 230,000,” the report said, according to The Associated Press. “An estimated half of those displaced crossed the border into the United States, which would leave about 115,000 internally displaced, most likely in the states of Chihuahua, Durango, Coahuila and Veracruz.” Despite the lack of official figures relating to displacement, the 2010 census carried out by the government found that hundreds of thousands of homes were left vacant in violence-plagued areas, including the dangerous border city Ciudad Juárez, where 111,103 of 488,785 houses had been abandoned. center_img LA PAZ, Bolivia – One hundred ninety-four kilograms (427 pounds) of cocaine hidden in a camouflaged truck were confiscated near Bolivia’s border with Peru on March 26, Col. Juan Luis Torrelio, the head of the Bolivian Special Forces Against Drug Trafficking (FELCN), said. Torrelio said the truck crossed the border near Yunguyo, Peru, and was bound for the Bolivian province of Santa Cruz, according to The cocaine was divided among 189 packages stashed beneath a false bottom in the truck. The driver, whose name was not released, was arrested, officials said. A day earlier, law enforcement officials found 26 kilograms (57 pounds) of cocaine in another vehicle in the same area, Torrelio said. SANTO DOMINGO, Dominican Republic – Dominican authorities have turned over an alleged narcotics drug trafficker so he can stand trial in Puerto Rico on charges of smuggling at least five kilograms (11 pounds) of cocaine and one kilogram (2.2 pounds) of heroin to the island. Miguel Ángel Martínez, also known as Miguel Ángel Santana Martínez, and “Nani,” was extradited to Puerto Rico last week, according to the Dominican Republic-based website Listín Martínez, 41, also is expected to be tried in a U.S. District Court, where he’ll face charges of criminal possession with the intent to distribute the narcotics, the Dominican National Drug Control Office said in a statement. U.S. authorities requested Martínez’s extradition in November 2010, the office said. BOGOTÁ, Colombia – At least three police officers were killed and three others wounded in an attack by members of the Revolutionary Armed Forces of Colombia (FARC) on the outskirts of Miranda, a town in the southwestern department of Cauca, officials said. The FARC is one of the region’s largest terrorist and narcotics trafficking organizations. The guerrillas surprised the police officers as they traveled along a road that leads from Miranda to the town of Florida, located in the neighboring department of Valle del Cauca, on March 27.

Searching ‘racist’ on Twitter brings up Trump as top result

first_imgGreg Sterling, a contributing editor at the website Search Engine Land, said the result suggests that “so many people are using the words ‘racist’ or ‘racism’ to respond to or describe Donald Trump, or there’s a concerted effort to associate Trump’s account with those terms.”Evidently, it is also possible that a large number of supporters defending Trump from charges of racism would also use the word ‘racist’ in their replies. Sterling said Twitter’s ranking algorithm for individual tweets “uses a variety of signals, including how recently the tweet was published, its relevance (personalization), user engagement with the tweet, the presence of rich media (such as video or images) and several other variables.”The analyst noted however that in 2007, a concerted effort known as “Google bombing” was able to manipulate search results for then-president George W. Bush to associate him with the term “miserable failure” on the search engine until the flaw was corrected.Kjerstin Thorson, a Michigan State University politics and social media professor, said it would require a detailed analysis to understand the reasons for the association of Trump and racism.But Thorson said “it’s not unlikely this could be an accurate representation of what people are saying” on Twitter and that bias is probably not a factor.”The platforms have gone out of their way to avoid any appearance of bias,” she said. Analysts said the news suggests Trump opponents, more than critics of any other Twitter account, have been labeling him as racist, although the social media giant itself did not confirm this was the case.Trump has been facing heightened criticism for his comments during protests over police brutality but has always dismissed suggestions that he is racist.  Twitter offered little in the way of explanation, pointing out only that its search algorithms may reflect what is happening on the platform.Trump, in the midst of a heated war with social media over what he claims is bias, recently signed an executive order calling for more oversight of internet platforms, a move which could prove difficult to enforce. US President Donald Trump appears as the first result of suggested accounts when users type “racist” into Twitter’s people search, it emerged Wednesday. The result, reported by the British news outlet The Independent and verified by AFP, highlights the intense discord around the president.Trump has more than 80 million followers, although there is much dispute about how many of them are genuine, active human Twitter users.center_img Topics :last_img read more
