The high level architecture (HLA) is a standard for federations of distributed simulations that exchange run-time data. HLA’s data distribution management (DDM) services reduce data delivered to simulations based on their declarations of data produced and required. The HLA specifications, including DDM, were changed substantially from the Department of Defense 1.3 standard to the IEEE 1516 stan...

OBJECTIVES The aim of this study was to compare the osteogenic effects of demineralized dentin matrix (DDM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) in rabbit calvarial defects with DDM and anorganic bovine bone (ABB) combined with rhBMP-2. MATERIALS AND METHODS Four round defects with 8-mm diameters were created in each rabbit calvaria. Each defect was treated w...

We first confirmed the osteoinductive property of human demineralized dentin matrix (DDM) histologically. Human DDM was prepared from vital, extracted teeth and implanted into the subcutaneous tissue in nude mice. The shape of the DDM was a particle type and its size varied from 0.4 to 0.8 mm. The hard tissue induction by 70 mg of the DDM was estimated at 4 weeks after implantation. The DDM ind...

Methylene dianiline (DDM) is a chemical intermediate in the production of isocyanates and other industrial chemicals, and it is hepatotoxic in humans. The acute hepatotoxicity of orally administered DDM was characterized in rats. Rats receiving DDM (25-225 mg/kg, per os) demonstrated a dose-dependent elevation in serum alanine aminotransferase activity, g-glutamyltransferase activity, and serum...

Study of Dynamic Decision Making (DDM) has been devoted to understanding the behaviors of decision makers facing dynamic decision making tasks. DDM involves decision tasks embedded in complex systems, the structure of which is not fully known to the decision makers. Previous DDM research mainly took an experimental approach, attempting to explain how people make dynamic decisions and how to imp...

Dynamic decision-making (DDM) research grew out of a perceived need for understanding how people control dynamic, complex, real-world systems. DDM has describable characteristics and, with some unavoidable sacrifice of realism, is suitable for study in a laboratory setting through the use of complex computer simulations commonly called ‘microworlds’. This paper presents a taxonomic definition o...

The objectives of the present study were to describe and compare the body composition variables determined by bioelectrical impedance (BIA) and the deuterium dilution method (DDM), to identify possible correlations and agreement between the two methods, and to construct a linear regression model including anthropometric measures. Obese adolescents were evaluated by anthropometric measures, and ...

Multiple-participant (MP) dynamic decision making (DDM) is encountered both in societal and technical systems. Unlike in single-participant (SP) DDM, no commonly accepted normative theory exists. The paper contributes to numerous attempts to overcome this state by classifying possible MP scenarios and connecting them with the normative SP DDM. This classification helps us to formulate open prob...

The Data Distribution Management (DDM) services, one category of HLA management services, control filters for data transmission and reception of data volume among simulators. In this paper, we propose design concept of DDM and show its implementation for RTI. The design concept of DDM is to minimize total amount of message that each federate and a federation process generate using the rate of R...

Distributed Data Mining (DDM) is the process of mining distributed and heterogeneous datasets. DDM is widely seen as a means of addressing the scalability issue of mining large data sets. Consequently, there is an emerging focus on optimisation of the DDM process. In this paper we present cost formulae for estimating the communication and computation time for different distributed data mining s...
