Grammatical Framework (GF) [5] is a grammar formalism for describing formal and natural languages. An application grammar in GF is usually written for a restricted language domain, e.g. to map a formal language to a natural language. A resource grammar, on the other hand, aims at a complete description of a natural languages. The language-independent grammar API (Application Programmer’s Interf...

In literary histories written in both Iran and the West it has generally be assumed that early modern Persian literary works are (technically inferior) copies of Western literary works. This has been and is still a claim. Almost no academically and scientifically sound works has substantiated this claim. While there is no point in denying a European influence on early modern Persian literature,...

This paper constructs a model in which the currency composition of national portfolios is an essential element in facilitating capital ‡ows between countries. In a two country environment, each country chooses optimal nominal bond portfolios in face of real and nominal risk. Current account de…cits are …nanced by increases in domestic currency debt, but balanced by increases in foreign currency...

Microwave power transmission (MPT) has had a long history before the more recent movement toward wireless power transmission (WPT). MPT can be applied not only to beam-type point-to-point WPT but also to an energy harvesting system fed from distributed or broadcasting radio waves. The key technology is the use of a rectenna, or rectifying antenna, to convert a microwave signal to a DC signal wi...

This paper proposes a new emotional model for Virtual Humans (VHs) in a conversational environment. As a part of a multi-users emotional 3D-chatting system, this paper focus on how to formulate and visualize the flow of emotional state defined by the Valence-ArousalDominance (VAD) parameters. From this flow of emotion over time, we successfully visualized the change of VHs’ emotional state thro...

The risks and returns associated with different choices of electricity generation technology cannot properly be considered in isolation. The paper considers their impact on an investing company, using Mean-Variance Portfolio (MVP) theory to identify optimal generation portfolios in liberalised electricity markets characterised by fuel, CO2, and electricity price risk. The paper demonstrates the...

I examine an investor’s portfolio allocation problem across multiple risky assets in the presence of return predictability when, in addition to the predictability evidence, the investor uses conditional asset pricing models to guide him in the portfolio selection decision. I also explore how the uncertainty associated with the model dynamics affects the investor’s optimal portfolio. To analyze ...

We consider a portfolio-choice problem with one risky and one safe asset, where the utility function exhibits decreasing absolute risk aversion (DARA). We show that the indirect utility function of the portfolio-choice problem need not exhibit DARA. However, if the (optimal) marginal propensity to invest is positive for both assets, which is true when the utility function exhibits nondecreasing...

This paper provides an intersection between portfolio choice theory and the elicitation of preferences under uncertainty. Theories of financial markets build on portfolio choice theory, which generally assumes that preferences are of a particularly simple kind, while research on preferences has revealed that people have more sophisticated preferences. This paper brings the two fields together b...
