Synthetic Environments (SE) facilitate an easy setup of various virtual realities since they are component-based and relatively easy maintainable. Through three stages, involving various types of stakeholders, the feasibility of SEs for cooperative product design (CPD) was explored: 1) Semi-structured group interviews with 19 engineers and designers assessed SE’s potential for CPD; 2) Implement...

Membrane-bound carboxypeptidase D (CPD) is a B-type carboxypeptidase that specifically cleaves C-terminal Arg or Lys from peptides and proteins. RAW 264.7 cells contained significant membrane-bound CPD activity as shown by activity assays and immunoprecipitation. To determine whether CPD can increase nitric oxide (NO) synthesis by releasing precursor Arg, cells were activated in Arg-free medium...

We give a precise characterization of two important classes of conditionally positive definite (CPD) kernels in terms of integral transforms of infinitely divisible distributions. In particular, we show that for any stationary CPD kernel A(x, y) = f(x − y), f is the log-characteristic function of a uniquely determined infinitely divisible distribution; further, for any additive CPD kernel A(x, ...

Previous studies reported that performance in texture segmentation was lower near the fovea than in the periphery. However, the exact cause of this phenomenon had been unknown. Experiment 1 replicated the central performance drop (CPD). Experiments 2 and 3 demonstrated that the previously reported CPD was due to a temporal factor, i.e. slower neural processing in central vision, rather than a s...

Based on the factors that influence the indoor comfort situation, a new index Comprehensive Percentage Dissatisfied CPD is proposed, which depends on the thermal factor, noise and indoor air quality. The calculation formulas in CPD are described in this paper and a method called gradation analysis is used to deduce the values of each coefficient in CPD. Finally, the index CPD is used to evaluat...
