Among many types of medical equipment, ultrasound diagnostic systems are widely used because of their convenience and safety. Performing an ultrasound examination involves good eye-hand coordination and the ability to integrate the acquired information over time and space. Some of these specialized skills may lack in some healthcare centers or for emergency situations. Tele-consultation is ther...

Potential scatter of simulation results caused for exampleby buckling, is still a challenging issue for the predictability. Principle component analysis (PCA) is a well-known mathematical method for data analysis. In order to characterize scatter PCA analysis was applied to the simulation results from a number of runs using all node positions at all time steps. For industrials relevant problems...

Polyethylene is the most popular man-made polymer. One way of making polyethylene consists in producing the polymer in the form of grains suspended by a gas flow of olefins (monomers), nitrogen and other hydrocarbons (alkanes). Industrials want to know the solubility of the monomers in the polyethylene grains, as the rate of the polymerization reaction is a direct function of this solubility. T...

The role of nitric oxide in cellular signaling in the past three decades has become one of the most rapidly growing areas in biology. Nitric oxide is a gas and a free radical with an unshared electron that can regulate an evergrowing list of biological processes. Nitric oxide is formed from L-arginine by a family of enzymes called nitric oxide synthases. These enzymes have a complex requirement...

physical decline and the necessity of redevelopment are never-ending challenges for built communities. neighborhoods undergo cycles of birth, growth, stabilization, decline and rejuvenation. redevelopment is a mechanism that can reduce the time an area is in decline and spur the process of revitalization. furthermore, redevelopment can provide incentives for a developer to build in a community ...

this research studies how the industry in iran emerged under the influence of industrial revolution and it tries to determine, by exploring the history and process of new industries’ formation within 19th and 20th centuries, the valuable role of these structures, particularly railway as an integral part of the historical memory of this land. as part of heritage, railway and its values underlie ...

En el context de la Comunitat Valenciana, els espais transició entre allò urbà i rural no tenen una consideració d’espais amb regulació específica, encara que reflecteixen situacions urbanes crítiques enfrontades a un territori escassa capacitat resposta. Una situació s’agreuja en posar focus als sòls industrials perifèrics o periurbans. Abordem seva anàlisi metodologia contrasta les aportacion...

This paper addresses the issue of automated organization of a personal image collection, in particular to respond to the emerging needs from a mobile camera phones. The issues related to browsing through large image collections acquired from such devices are first discussed. In contrast with metadata-less collections, which necessarily rely on image content, we propose a collection organization...

This paper examines the vertical integration level of environmentally sustainable and non-sustainable companies. The first part develops the theoretical foundation for linking sustainability strategies to organizational structure. The second part empirically examines the vertical integration level of 144 sustainability-focused companies in 9 different industries. The results demonstrate that su...

This paper proposes a model for the estimation of time series returns of illiquid asset portfolios. The model has four major advantages. First, the estimators are arithmetic averages of individual asset returns (or their proxies), so they strictly correspond to the portfolio returns. Second, the model is able to estimate returns of arbitrary-weighted portfolios, including equalweighted, price-w...
