I was a bit … weird … as a teenager. As part of an Air Force family we moved frequently, and like most teenagers trying to distinguish themselves from their peers, I tried to use my strengths — an active intellect and an ease at working with abstractions — as a way of establishing myself in the new schools I constantly found myself in. I was the “smart kid”, the one who took to carrying around large books with titles such as “Principia Mathematica” by Bertrand Russell and Whitehead Alfred North in order to impress people with my intelligence okay, so perhaps my social intelligence was not quite as well developed at that stage. For those of you not familiar with the work, the Principia Mathematica was a book on logic, but its real value lay in the fact that the logic in question was explored not by making assertions in English but rather by attempting to construct all possible logical propositions using what would today be called symbolic logic or propositional calculus. North and Russell attempted to do this for every possible logical statement possible — in essence trying to ground mathematics in logic. As an intellectual achievement it was truly stunning. As a resource, it was practically useless, and was, even more ironically, doomed to failure even before it began. My dance card stayed empty through much of high school and well into my college years until I found that the love of logic actually translated pretty nicely to programming computers, and that occasionally taking a shower, wearing decent clothes, being polite and kindly if somewhat puppy-dog innocent and taking the occasional risk in asking out women worked far better than trying to look like a genius.

Refuse-derived Fuels: From Waste to Energy
RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. This graph view is the easiest possible mental model for RDF and is often used in easy-to-understand visual explanations. The RDF 1.
(Mb). Date. efficient SPARQL solution on the compressed RDF datasets is also required.
These data descriptors are used to distinguish and define the characteristics of knowledge resources in a specific domain. Using controlled vocabularies the resources can be queried, retrieved, analysed and linked to other relevant information objects. Patricia Harpring 1 introduced the following definition of controlled vocabulary CV :. It typically includes preferred and variant terms and has a defined scope or describes a specific domain.
There are many different types of controlled vocabularies, the most common among them are:. Diagram 1. In this example, the Archeological site is a Universal abstract class, whereas Athens is an instance of Archaeological site class and a Particular that represents the exact and real archaeological site studied and described in the system. Controlled vocabularies CVs are prominently used in many domains of research and industry:.
CVs provide and document data semantics. CVs are one of the tools used for this mission. W3C developed specifications and standards to support the usage of CVs in the context of the Semantic Web in order to express knowledge in a machine-readable format that can be used by computer applications to interpret it. Usage of RDF for CVs representation allows metadata to be shared and retrieved across different applications.
Earlier today, Andrew Chamberlain on Twitter , observed that at the end of this month the current economic expansion in the U. The table is informative, but can we do something more graphical? Yes we can. I also fit a regression line through the points. What this shows is that while expansions blue have gotten longer over time, recessions red have gotten shorter over time. I often use recession shading on line plots, see here for handy R code.
This chart plots the date for NBER expansions/recession on the x axis rdf % mutate(TroughLag = lag(Trough), # find last.
Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. Refuse-derived fuels RDF are produced from municipal solid waste MSW that has been shredded then subsequently treated with pressurized steam in autoclaves. SRFs and RDFs can be derived from household, commercial, or industrial wastes and other combustible waste streams. On the other hand recyclable materials should not be excluded from SRFs because such an exclusion could lead to disposal of these materials and wastage of the resources embedded in them.
Conversion of waste into refuse-derived fuels or solid recovered fuels serves two purposes — it reduces the volume of waste sent to landfills thereby solving problems in the waste sector, and it provides alternative fuels for energy-intensive industries. RDFs are used for energy recovery in cement kilns, power stations, and industrial boilers as substitute to fossil fuels. RDFs and SRFs have proven to be effective substitutes to fossil fuels because they have low production costs but have significant thermal value.
A standard has been developed to measure the biomass carbon fraction of refuse-derived fuels and solid recovered fuels. This standard, EN , determines the biogenic carbon fraction of solid recovered fuels using radiocarbon dating techniques. Both standards use the radiocarbon dating technique to distinguish the biogenic fractions of samples from their fossil-based components. For details on how radiocarbon dating can distinguish biogenic components from fossil-based ones, read more about ASTM D Greenhouse gas protocols in Europe have cap carbon dioxide emissions in certain industries.
Companies can obtain carbon credits if they do not exceed their annual CO2 emission limits. These carbon credits have monetary value and are tradable under the European Union Emissions Trading Scheme.
For example, the date is always part of an online order. Examples and other code fragments are serialized using RDF Turtle notation.
Its URI is:. See a description of this connection in the Class Hierarchy section, below. PoMS’s RDF data is a representation of the structured data model upon which PoMS’s database was created, and which in turn is based on the factoid model. Historians well understand that rather direct statements of the kinds represented might well overly simplify what might be a subtle and complex reality. The structure shown here is simplified in various respects from the one that was actually used in the Factoid Ontology itself and in PoMS.
Even so, it represents something important about the structure of PoMS data, and you can see this overarching structure, incorporated into PoMS’s ontology, and thus shown in both the ontology’s class hierarchy and class relationship diagrams presented below. The SubClass idea in Ontologies is to some extent hierarchial, and this figure emphasises this characteristic. Bear this in mind while reading the overview below.

Refuse-derived fuel RDF is a fuel produced from various types of waste such as municipal solid waste MSW , industrial waste or commercial waste. RDF consists largely of combustible components of such waste, as non recyclable plastics not including PVC , paper cardboard, labels, and other corrugated materials. These fractions are separated by different processing steps, such as screening, air classification, ballistic separation, separation of ferrous and non ferrous materials, glass, stones and other foreign materials and shredding into a uniform grain size, or also pelletized in order to produce a homogeneous material which can be used as substitute for fossil fuels in e.
RDF can be also further specified into e. There is no universal exact classification or specification which is used for such materials.

Our technique, called -triples, uses the predicate to vertically partition the dataset into disjoint subsets of pairs subject, object , one per predicate. These subsets are represented as binary matrices of subjects objects in which 1-bits mean that the corresponding triple exists in the dataset. This model results in very sparse matrices, which are efficiently compressed using -trees.
We enhance this model with two compact indexes listing the predicates related to each different subject and object in the dataset, in order to address the specific weaknesses of vertically partitioned representations. The resulting technique not only achieves by far the most compressed representations, but also achieves the best overall performance for RDF retrieval in our experimental setup.
Our approach uses up to 10 times less space than a state-of-the-art baseline and outperforms its time performance by several orders of magnitude on the most basic query patterns.
