Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
Crosslinking chemistry for high-performance polymer networks
(Elsevier, 1994-11)
A new thermally reactive monomer has been designed and synthesized that brings novel crosslinking chemistry to high-performance polymers. This monomer (XTA) is a derivative of terephthalic acid and was based on the thermal ...
A multi-dynamic-factor model for stock returns
(Elsevier, 1992)
In this paper, we define dynamic and static factors and distinguish between the dynamic and static structure of asset excess returns. We examine the value-weighted market portfolio as a dynamic factor and propose an ...
Determination of the electro-optical coefficient r33 and refractive index of para-substituted poly([gamma]-benzyl--glutamate) derivatives
(Elsevier, 1994-01)
The electro-optical coefficient r33 and refractive index of films of poly([gamma]-benzyl--glutamate) and the p-nitro, p-fluoro and p-trifluoromethyl derivatives were determined as a way to assess the non-linear optical ...
Asset pricing with a factor-arch covariance structure : Empirical estimates for treasury bills
(Elsevier, 1990)
In this paper we suggest using the FACTOR-ARCH model as a parsimonious structure for the conditional covariance matrix of asset excess returns. This structure allows us to study the dynamic relationship between asset risk ...
The WALRAS Algorithm: A Convergent Distributed Implementation of General Equilibrium Outcomes
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-08)
The WALRAS algorithm calculates competitive equilibria via a distributed tatonnement-like process, in which agents submit single-good demand functions to market-clearing auctions. The algorithm is asynchronous and decentralized ...
Interfacial adhesion and toughening mechanisms in an alloy of polycarbonate/polyethylene
(Elsevier, 1992)
Interfacial adhesion and toughening mechanisms in an alloy of polycarbonate/polyethylene (PC/PE) are investigated using transmission electron microscopy. In contrast to the general speculation, it is found that the PE ...
Teaching with difference: A response to Angela Calabrese Barton: Teaching science with homeless children: Pedagogy, representation, and identity
(John Wiley & Sons, Inc., 1998-04)
No abstract.
Price indeterminacy and bargaining in a market with indivisibilities
(Elsevier, 1993)
We consider an exchange market for an indivisible, heterogeneous good where pairs of buyers and sellers bargain over prices in different transactions. A stable outcome in one negotiation cannot be uniquely determined by ...
