Based on the subdistrict (jie-dao) data from 1982 and 1990 national population censuses, this research employs two approaches to investigate the urban population change patterns in Shenyang, China. The density function approach examines what function best characterizes its density distribution, how the density pattern has changed over time, how many centers can be identified in the city, and ho...

INTRODUCTION Recreational and transportation infrastructure can promote physical activity among children and adolescents. The Play Across Boston community-based research project sought to estimate and compare playground renovation rates across Boston areas before and after a playground quality assessment, to describe changes in playground quality among a subset of parks, and to document feature...

In this note we consider M/D/1/N queue with renovation and derive analytic expressions for the following performance characteristics: stationary loss rate, moments of the number in the system. Moments of consecutive losses, waiting/sojourn time (as introduced in [1]) are out of scope. The motivation for studying these characteristics is in the comparison of renovation with known active queue me...

The paper is concerned with the technological process of renovation of shafts used in industrial manufacturing for extruding of sheet material. In the classical renovation technologies, a chrome based coating is applied to the working surface of the shaft in galvanic baths. The process, however, is known to be exclusively harmful due to the waste cyanide products. In this work, we present an ad...

We have studied how energy efficiency is discussed by professionals during renovation of multifamily dwellings, in order to capture how barriers in relation to energy measures are appearing, disappearing and transformed during the process. We did participatory observations of renovation meetings, conducted interviews with the involved professionals and studied-related documents. Our intentions ...

We extend Borovkov’s renovation theory to obtain criteria for coupling-convergence of stochastic processes that do not necessarily obey stochastic recursions. The results are applied to an “infinite bin model”, a particular system that is an abstraction of a stochastic ordered graph, i.e., a graph on the integers that has (i, j), i < j, as an edge, with probability p, independently from edge to...

When a compiler is designed carefully, it is possible to extract its grammar. We reengineer the extracted grammar to one that is geared towards reengineering. From this reengineering grammar we generate an architecture called a software renovation factory. This includes: generic analysis and transformation functionality and a native pattern language using the concrete syntax of the language for...

This intervention study was designed to show the effects of the renovation of moisture and mold damaged school building on the schoolchildren’s health and exposure. Microbial sampling from indoor air of the school and a health questionnaire study were performed before and after renovation. The results were compared to those from non-damaged reference school. The effect of a thorough renovation ...

means of increasing worker productivity so that higher wages can be paid and as a means of getting the work done with a smaller labor force. A part, at least, of the difference between the level of mechanization here and abroad is explained by differences in wage rates. As wages go up, it pays to use more machines and fewer men. In recent years, for example, it took about 67 gallons of milk to ...
