This article examines the role of espionage in defending against cyber-attacks on infrastructural firms. We analyze the problem using a game between a government, an infrastructural firm and an attacker. If the attacker successfully breaches the IT security defenses of the infrastructural firm, primary losses accrue to that firm while widespread collateral losses accrue to the rest of the econo...

A 2D finite-differences time-domain full-wave code is used to simulate the measurements of plasma filaments with fixed frequency O-mode reflectometry. The plasma is modeled by a linear slab plasma plus a Gaussian perturbation propagating in a direction that can vary from poloidal to radial. The plasma background density gradient is chosen in agreement with the steep edge transport barrier of H-...

The emergence of systems biology is bringing forth a new set of challenges for advancing science and technology. Defining ways of studying biological systems on a global level, integrating large and disparate data types, and dealing with the infrastructural changes necessary to carry out systems biology, are just a few of the extraordinary tasks of this growing discipline. Despite these challen...

How does IT outsourcing affect firm performance? What is the role of internal IT experience in IT outsourcing? Prior research has provided different answers for these two questions. This study attempts to address the inconsistencies in the literature. We distinguish between knowledge intensive IT outsourcing (KITO) and infrastructural IT outsourcing (IITO) and suggest that these two types of IT...

The scaling and other quantifiable properties of a network have recently been proven valuable in understanding the robustness and vulnerability properties of various societal and infrastructural networks. In this paper we revisit the algorithms for computing various quantifiable properties of a planar road network and consider the algorithmic complexity and scalability in the light of recent te...

Software process modeling and simulation have become effective tools for support of software process management and improvement over the past two decades. They have recently been integrated into the Trustworthy Process Management Framework (TPMF) as the infrastructural components to facilitate the delivery of trustworthy software products. This paper proposes the concept of Trustworthy Software...

We present a distributed geographic information system (DGIS) built on a distributed high performance computing environment using a number of software infrastructural building blocks and computational resources interconnected by an ATM-based broadband network. Archiving, access and processing of scientific data are discussed in the context of geographic and environmental applications with speci...

We discuss applications of high resolution geostationary satellite imagery and distributed high performance computing facilities for the storage, processing and delivery of satellite data products. We describe our system which is built on a distributed high performance computing environment using a number of software infrastructural building blocks and computational resources interconnected by ...
