Simulation of Consumption in District Heating Systems

by Daniela Popescu, Florina Ungureanu, Elena Serban
"... Abstract:- District heating companies from Europe had an annual turnover (2005) of 19.5 billion Euro and supplies heat to more than 100 million people. District heating contributes to higher energy efficiency, greater security of supply and lower carbon dioxide emissions. There is a need to strength ..."

, the mentality is different: the District Heating Company evaluates the quantity of heat for each building and delivers it through a distribution network to substations. A number of 20-30 buildings, usually blocks of flats, are connected to the substation and must share the quantity of heat

Longer-term effects of Head Start

by Eliana Garces , Duncan Thomas , Janet Currie Ucla , Nber - American Economic Review , 2002
"... Abstract Public early intervention programs like Head Start are often justified as investments in children. Yet nothing is known about the long-term effects of Head Start. This paper draws on unique data from the Panel Study of Income Dynamics to provide new evidence on the effects of Head Start on ..."

, in 1995, questions about participation in Head Start and other preschools were included in the interviews and asked of all adults age 18 through 30. These questions make it feasible, for the first time, to track participants in Head Start for a long period. Second, because the PSID is a panel which

Community Effort in Online Groups: Who Does the Work and Why?

by Brian Butler, Lee Sproull, Sara Kiesler, Robert Kraut , 2001
"... this paper examines these relationships in more detail, and asks whether contributions, perceived benefits, and the relationships among them were different for owners of the lists (formal leaders), active posters, and lurkers of the groups, and for nonwork-related and work related groups. To test ou ..."

The Buildings of Dalhousie University Buildings Home About the Project Chronology Building Index

by Bernard M. Cain, Building Timber, Bernard M. Cain, Building Timber , 1968
"... The Bernard N. Cain (Q) Building was built as an extension of the A.L MacDonald (D) Building, as a new timber structures engineering laboratory which would replace the older, unsatisfactory one on the Nova Scotia Technical College's campus and thus keep pace with the then-rapid growth of timber ..."

,520 square feet, two stories and designed for vertical expansion. The building's 30 ' by 10 ' floor is three feet thick and its two original loading systems and jacking devices could withstand up to 20 tons of force, up or down. The timber laboratory was also originally equipped with a 10-ton

Seismic Behavior of Multi-Storied Buildings

by Venkatasai Ram Kumar N, S. V. Satyanarayana, J. Usha Kranti
"... The present study deals with the comparison of base shear of multi storied buildings with dimensions 20x20mts, 30x30mts,40x40mts,60x60mts at different zones and different types of soils as per IS:1893(part: I):2002. A total of 224 multi storied buildings are analyzed for this paper. This work helps ..."

Ceramic building material (CBM)

by Roman Durnovaria, Kayt Brown, Kayt Brown
"... A total of 16420 fragments (926743g) of Roman ceramic building material was recovered from the three areas excavated, of which 61 fragments were retained. A range of different tile types were identified (Table CBM1), however the material was in a very fragmentary state with few complete dimensions p ..."

Improving Identification of Difficult Small Classes by Balancing Class Distribution [ftp://ftp.cs.uta.fi/pub/reports/pdf/A-2001-2.pdf

by Jorma Laurikkala , 2001
"... Abstract. We studied three methods to improve identification of difficult small classes by balancing imbalanced class distribution with data reduction. The new method, neighborhood cleaning rule (NCL), outperformed simple random and one-sided selection methods in experiments with ten data sets. All ..."

reduction methods improved identification of small classes (20-30%), but the differences were insignificant. However, significant differences in accuracies, true-positive rates and true-negative rates obtained with the 3-nearest neighbor method and C4.5 from the reduced data favored NCL. The results suggest
