This paper analyzes the dynamic incentives for technology adoption under a transferable permits system, which allows for strategic trading on the permit market. Initially, firms can invest both in low– emitting production technologies and trade permits. In the model, technology adoption and allowance price are generated endogenously and are inter–dependent. It is shown that the non–cooperative ...

In this thesis, we present interest rate models and a credit risk model, all driven by time-inhomogeneous Lévy processes, i.e. stochastic processes whose increments are independent but in general not stationary. In the interest rate part, we discuss a Heath–Jarrow–Morton forward rate model (the Lévy term structure model), a model for forward bond prices (the Lévy forward price model) and a Libo...

An oral sustained-release floating tablet formulation of metformin HCl was designed and developed. Effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and HPMC-PEO polymer combination, respectively. Tablet composition was optimized by response surface methodology (RSM). Seventeen (17) trial formulations were analyzed according to Box-Behnken desi...

As an entry for the 1998 Gordon Bell price/performance prize, we present two calculations from the disciplines of condensed matter physics and astrophysics. The simulations were performed on a 70 processor DEC Alpha cluster (Avalon) constructed entirely from commodity personal computer technology and freely available software, for a cost of 152 thousand dollars. Avalon performed a 60 million pa...

The main objective of the present study was to formulate gastroretentive effervescent sustained release drug delivery systems of risperidone floating tablets with the help of Methocel® K15, Ethocel® standard 7FP premium, Eudragit ® RS100 sustained release polymers to improve its safety profile, bioavailability and patient compliance. Risperidone floating tablets were formulated by wet granulati...

With the aim of extending the use of integrated variational principles on fluid and deckplate to the large deflection analysis of floating roofs, this paper investigates the significance of theflexural and membrane components in the formulations of the deck plate. Applying integratedvariational principles on deck plate and fluid facilitate the treatment of the compatibility ofdeformation betwee...

T single-product firms with different quality levels and fixed limited capacities engage in sequential price competition in an essentially deterministic model where customers have heterogeneous valuations for both products. We develop conditions under which the leader (she) can take strategic advantage of her limited capacity by pricing relatively low, purposefully creating shortages and leavin...

A commonly observed two-stage pricing strategy for a custom-made product involves a prepurchase entry fee for a potential consumer and a purchase price if he decides to buy the product. We solve and compare two settings: In the first, the firm does not commit in advance to the second-stage price and in the second, the firm does. We show that without a commitment mechanism, the two price points ...

this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...
