In emerging electric power systems, increased transactions often lead to the situations where the system no longer remains in secure operating region. The flexible Ac transmission system (FACTS) controllers can play an important role in the power system security enhancement. However, due to high capital investment, it is necessary to locate these controllers optimally in the power system. FACTS...

Wireless networking of sensor devices is becoming more pervasive as technology, particularly miniaturization makes more sensing applications possible. Power efficient operating systems and network protocols are key components for wireless sensing applications. This paper presents a low-power operating system and associated wireless protocols that have been developed to operate in a centrally sy...

Monolithicand micro-kernel-based operating systems such as Unix have failed to provide application developers with sufficient flexibility. They provide a host of inefficient and often inappropriate abstractions that prevent applications from accessing the hardware to exploit efficiency gains. These problems motivated the Grasshopper project to build a new operating system designed to explicitly...

Application Model Computational Reality Mapping implementation must be tailorable. For example, a reference which crosses a machine boundary may use a name server but when its target is on the local machine, it should be possible to use a simple pointer. A Framework for Mapping π π defines a uniform object model for both application and system software. Its architecture is based on three main n...

Ability to support various business models has been recognized as one of the essential competitive advantages of companies operating in global networked business environment. The use of several business models simultaneously, requires availability of flexible business process models. Flexibility of business process models, in turn, depends on appropriate information systems support. One of the ...

Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...

The design of the computer system was significantly changed due to the emergence and popularization of the multicore processors. Moving to the advanced multicore processors, moving to the heterogeneous computer systems and increasing of the integrity level between computer system components are the main trends of the computer systems development. Significant changes in the computer systems desi...

This paper provides causal evidence of flexible operating strategies affecting capital structure of firms. I exploit the appealing setting of the European labor market to show that the use of employment contracts that provide firms with a greater operating flexibility in terms of less costly firing promotes debt financing. I build the identification strategy on the exogenous inter-temporal and ...
