bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. this microstructure has shown ultimate tensile strength of about 2.2 gpa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 hv and impact toughness in the range of 30 to 40 mpa m1/2. with ca...

The major toxaphene metabolites in sediment and soils (2-exo,3-endo,6-exo,8,9,10-hexachlorobornane [B6-923] and 2-endo,3-exo,5-endo,6-exo,8,9,10-heptachlorobornane [B7-1001]) were incubated with the isolated gram-negative bacterium Dehalospirillum multivorans. Within 14 d, biotransformation of B7-1001 was nearly quantitative, resulting in two penta- and six hexachlorobornanes, as well as one un...

Herein, we characterize a generally applicable transformation of fatty acid epoxides by lipoxygenase (LOX) enzymes that results in the formation of a five-membered endoperoxide ring in the end product. We demonstrated this transformation using soybean LOX-1 in the metabolism of 15,16-epoxy-α-linolenic acid, and murine platelet-type 12-LOX and human 15-LOX-1 in the metabolism of 14,15-epoxyeicos...

Modelling variability in software product lines (SPL) development is receiving a lot of attention in current years, building on the idea that product derivation could be automatically derived from a product line through model transformations. Software Product Line development involves the explicit management of variability that has to be encompassed by the software artifacts, in particular by t...

This paper presents a fundamental research on customer requirements modelling and propagation throughout the whole product development lifecycle. A theoretical mapping model, from customer requirements to quality characteristics, is established. It covers three processes, i.e., the qualification and classification of customer requirements, the generation and transformation of product quality ch...

The displacive transformation classification proposed at ICOMAT 79 [I] is reviewed in light of recent progress in mechanistic understanding. Issues considered include distinctions between shuffle transformation vs. self-accommodating shear, dilatation vs. shear-dominant transformation, and nucleated vs. continuous transformation. 1. HISTORICAL INTRODUCTION Cohen, Olson and Clapp (COC) at ICOMAT...

New product development has changed signi®cantly over the last decade and management control systems have played an important role in this transformation. This study draws on Galbraith's concept of uncertainty and investigates the relationship between project uncertainty, product strategy and management control systems. It also explores whether these systems help or, as argued in the innovation...

Abstract An affine de Casteljau type algorithm to compute q−Bernstein Bézier curves is introduced and its intermediate points are obtained explicitly in two ways. Furthermore we define a tensor product patch, based on this algorithm, depending on two parameters. Degree elevation procedure is studied. The matrix representation of tensor product patch is given and we find the transformation matri...

This paper presents the PLiBS (Product Line Behavior Synthesis), an Eclipse-based tool for modeling and deriving behavior aspects in Software Product Lines (SPL). PLiBS allows specifying SPL behaviors using UML2 sequence diagrams extended by variability mechanisms. PLiBS implements a two-step approach to derive product behaviors. The first one uses model transformation to specialize sequence di...

Interoperation between business partners is extremely important. However, most product data produced in many firms are considered as ad hoc and are not qualified for interoperation. To solve this problem, this paper has proposed a concept-centric definition transformation approach, which transforms irregular local product definitions from different data sources to a set of canonical local produ...
