in chemical engineering, several processes are represented by singular boundary value problems. in general, classical numerical methods fail to produce good approximations for the singular boundary value problems. in this paper, chebyshev finite difference (chfd) method and dtm-pad´e method, which is a combination of differential transform method (dtm) and pad´e approximant, are applied for sol...

In discussions on genetic engineering and plant breeding, the intrinsic value of plants and crops is used as an argument against this technology. This paper focuses on the new field of plant genomics, which, according to some, is almost the same as genetic engineering. This raises the question whether the intrinsic value of plants could also be used as an argument against plant genomics. We wil...

The enterprise value network engineering is an effective social business carrier, but the “sudden adversity” or “sudden disaster” often occurs to every internal enterprise in the value network engineering system or outside, which makes the enterprise have to have a good emergency management ability in order to avoid the final crisis. The article uses a system analysis approach to construct a tw...

This paper presents a value-based software process framework that has been derived from the 4+1 theory of value-based software engineering (VBSE). The value-based process framework integrates the four component theories – dependency, utility, decision, and control, to the central theory W, and orients itself as a 7-step process guide to practice value-based software engineering. We also illustr...
