The capability to reallocate items|e.g. tasks, securities, bandwidth slices, Mega Watt hours of electricity, and collectibles|is a key feature in automated negotiation. Especially when agents have preferences over combinations of items, this is highly nontrivial. Marginal cost based reallocation leads to an anytime algorithm where every agent's utility increases monotonically over time. Di eren...

In this study, balanced and single ended class-E power amplifiers (PAs) were designed and realized for 3.5–3.8GHz band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations were made on low loss Rogers RT5880 dielectric material which has 0.254mm thickness and 2.2 dielectric constant. Proposed balanced class-E PA has approximately 20W (43 dBm) output power with 80%...

I this paper, we analyze the contracting issues that arise in collaborative services, such as consulting, financial planning, and information technology outsourcing. In particular, we investigate how the choice of contract type—among fixed-fee, time-and-materials, and performance-based contracts—is driven by the service environment characteristics. We find that fixed-fee contracts contingent on...

the complexity and diversity of international assignment or license of iprs and the territoriality principle, makes determining their applicable law difficult. the rules governing iprs, are distinct from applicable law to contractual issues, hence the importance of characterization in these contracts. party autonomy and the discretion of courts are faced with restrictions including competition ...

H igh price volatility and the risk are the main features of commodity markets. One way to reduce this risk is to apply the hedging policy by future contracts. In this regard, in this paper, we will calculate the optimal hedging ratios for OPEC oil. In this study, besides the multivariate GARCH models, for the first time we use conditional copula models for modelling dependence struc...

During the development of component-based software systems, it is often impractical or even impossible to include all development information into the source code. Instead, specialized languages are used to describe components and systems on different levels of abstraction or from different viewpoints: Component-based architecture models and contracts, for example, can be used to describe the s...
