Free Book Search.net Free Book Search's document search tool is designed to return the maximum number of online documents from specific types of websites as per the users' choice. We have made this search portal very robust so that using the tools on this page, if a document exists somewhere - even hidden away - on the Internet, you will find it here. This is one of the only online tools that will actually find books and documents on non-book sites. Most other tools sift through digital libraries or known locations of e-books and documents, our searches also scan private collections that are normally hidden. There are a few methods for finding documents, and we have tried to incorporate all of them in one place by using the 'radio buttons'. You may need to try using a few of the search techniques to find what you are looking for, and you may need to sift through a number of documents. We have included a military search to search official military sites.
Natural gas system in US is leaking methane Officials in the United States have underestimated how much methane—a potent greenhouse gas—is leaking from the country’s natural gas system, experts warn. The findings, published in the journal Science, are based on a review of more than 200 earlier studies and confirm that methane emissions are considerably higher than official estimates, including those by the Environmental Protection Agency (EPA). Natural gas consists predominantly of methane. Even small leaks from the natural gas system are important because methane is a greenhouse gas that is about 30 times more potent than carbon dioxide. “People who go out and actually measure methane pretty consistently find more emissions than we expect,” says the lead author of the new analysis, Adam Brandt, an assistant professor of energy resources engineering at Stanford University. “Atmospheric tests covering the entire country indicate emissions around 50 percent more than EPA estimates,” says Brandt. EPA’s estimates are too low

Gundersen 03.10.2013 Recevant de nombreuses questions sur la situation à la centrale nucléaire de Fukushima Daiichi, Arnie Gundersen, ingénieur en chef de Fairewinds, nous propose une visite du site en vidéo, combinant images satellite, animations 3D et photographies. Nous aurons ainsi une vision du site depuis la construction de la première unité, Daiichi 1, jusqu'aux 2 bâtiments les plus récents des unités 5 et 6. Nous verrons que dès la conception de la première unité en 1965, qui servira de modèle à ses trois voisines construites par la suite, les décisions maîtresses prises par les ingénieurs des sociétés General Electric et EBASCO, basées en premier lieu sur des considérations financières de réduction des coûts, scelleront dans le béton le sort du site et de la nation Japonaise entière, plus de 45 ans plus tard. La visite commencera par le parc des citernes de stockage de l'eau contaminée, qui ne cesse de s'étendre. Comme le dit Gundersen dans une autre de ses productions que j'espère aborder également,
Semantic search Guha et al. distinguish two major forms of search: navigational and research. In navigational search, the user is using the search engine as a navigation tool to navigate to a particular intended document. Semantic search is not applicable to navigational searches. In research search, the user provides the search engine with a phrase which is intended to denote an object about which the user is trying to gather/research information. Rather than using ranking algorithms such as Google's PageRank to predict relevancy, semantic search uses semantics, or the science of meaning in language, to produce highly relevant search results. Disambiguation Such processes make use of other information present in a semantic analysis system and takes into account the meanings of other words present in the sentence and in the rest of the text. Every node of the network (called Synset) groups a set of synonyms which represent the same lexical concept (called Synsets) and can contain:
the Pattern which Connects from KaliYuga to Tao: Complexity of Tao The definition of complexity of a system is itself complex: several authors in different historical periods in different disciplines have used different definitions. Seth Lloyd ranked in the first 90s at least 32 examples of definitions, including information (Shannon), entropy (Gibbs-Boltzmann), algorithmic complexity, self-delimiting code length, minimum length description, number of parameters, the degrees of freedom or dimensions, mutual information or channel capacity, correlation, fractal dimension, self-similarity, sophistication, size of the machine topology, difference in a subtree graph, temporal or spatial complexity of calculation, logic depth or thermodynamics, arge-scale order, self-organization, edge of chaos and others. Generally, complex systems may have the following features:Very large number of elements and connections Difficult to determine boundaries It can be difficult to determine the boundaries of a complex system. May be open May have a memory May be nested
Loss of milkweeds means monarchs could go extinct There is a good chance that monarch butterflies will face a “quasi-extinction” in the next 20 years, researchers warn. Despite a favorable summer in 2015, the eastern migratory population declined 84 percent between 1996 and 2014. Quasi-extinction means that so few individual monarchs would exist that their migratory patterns would collapse and the population likely wouldn’t recover. For a new study, published in the journal Scientific Reports, researchers used historic trends to develop models that forecast future monarch populations. The team factored weather patterns and natural variations into the simulations and figured out the probability of the overall population sinking to various thresholds that could lead to quasi-extinction. Saving the monarchs from extinction will require “all hands on deck.” The researchers tracked the current population of monarchs by measuring the area of land they occupied while overwintering in central Mexico.

Glean Comparison Search: An Educational Research and Search Tool PageRank Mathematical PageRanks for a simple network, expressed as percentages. (Google uses a logarithmic scale.) Page C has a higher PageRank than Page E, even though there are fewer links to C; the one link to C comes from an important page and hence is of high value. PageRank (PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank works by counting the number and quality of links to a page to determine a rough estimate of how important the website is. It is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known. Description Cartoon illustrating the basic principle of PageRank. Other factors like Author Rank can contribute to the importance of an entity. Numerous academic papers concerning PageRank have been published since Page and Brin's original paper. In practice, the PageRank concept may be vulnerable to manipulation. History
