A common observation made when computing chemically reacting flows is how central processing unit (CPU)-intensive these are in comparison to cold flow cases. The update of tens or hundreds of species with hundreds or thousands of reactions can easily consume more than 95% of the total CPU time. In many cases, the region where reactions (combustion) are actually taking place comprises only a very small percentage of the volume. Typical examples are flame fronts propagating through a domain. In such cases, only a small fraction of points/cells needs a full chemistry update. This leads to extreme load imbalances on parallel machines. The purpose of the present work is to develop a methodology to balance the work in an optimal way.

Points that require a full chemistry update are identified, gathered and distributed across the network, so that work is evenly distributed. Once the chemistry has been updated, the unknowns are gathered back.

The procedure has been found to work extremely well, leading to optimal load balance with insignificant communication overheads.

In many production runs, the procedure leads to a reduction in CPU requirements of more than an order of magnitude. This allows much larger and longer runs, improving accuracy and statistics.

The procedure has allowed the calculation of chemically reacting flow cases that were hitherto not possible.

To the authors’ knowledge, this type of load balancing has not been published before.

This study aims to evaluate blast loads on and the response of submerged structures.

An arbitrary Lagrangian–Eulerian method is developed to model fluid–structure interaction (FSI) problems of close-in underwater explosions (UNDEX). The “fluid” part provides the loads for the structure considers air, water and high explosive materials. The spatial discretization for the fluid domain is performed with a second-order vertex-based finite volume scheme with a tangent of hyperbola interface capturing technique. The temporal discretization is based on explicit Runge–Kutta methods. The structure is described by a large-deformation Lagrangian formulation and discretized via finite elements. First, one-dimensional test cases are given to show that the numerical method is free of mesh movement effects. Thereafter, three-dimensional FSI problems of close-in UNDEX are studied. Finally, the computation of UNDEX near a ship compartment is performed.

The difference in the flow mechanisms between rigid targets and deforming targets is quantified and evaluated.

Cavitation is modeled only approximately and may require further refinement/modeling.

The results demonstrate that the proposed numerical method is accurate, robust and versatile for practical use.

Better design of naval infrastructure [such as bridges, ports, etc.].

To the best of the authors’ knowledge, this study has been conducted for the first time.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

This chapter explores the origins of the theme of competitive advantage in 19th and early 20th century economics. This theme, which forms the core of modern Strategic Management, was a battleground for debates about the value of abstract theory versus observations about real-life events. Intellectual genealogies, citations, and other sources show the central roles played by the University of Vienna and Harvard University. These two institutions strongly influenced the theory of monopolistic competition as well as all three modern views of competitive advantage – the industrial as expressed by Porter, the resource-based as expressed by Penrose, and the evolutionary as expressed by Schumpeter.

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

This paper develops a framework for understanding history as a source of competitive advantage. Prior research suggests that some firms enjoy preferential access to resources as a result of their past. Historians, by contrast, understand past events as more than an objective account of reality. History also has an interpretive function. History is a social and rhetorical construction that can be shaped and manipulated to motivate, persuade, and frame action, both within and outside an organization. Viewed as a malleable construct, the capacity to manage history can, itself, be a rare and inimitable resource.

It is now widely accepted that the institutional interventions of states are a foundational influence on the dynamics of organizational forms. But why do states act? In this chapter, we apply the behavioral theory of the firm to develop an explanation of state actions based on the fact that they are boundedly rational rivals. The instrument of state competition we examine is the founding of business incubators, a primary tool in the entrepreneurial strategy of economic development. We predict that business incubators are more likely to be founded in a state when (1) the state falls behind comparable states in the indicators of economic development; (2) the state falls behind its own historical trajectories of economic development; (3) the state has slack resources in the form of budget surpluses; (4) comparable and rival states adopt incubators as a development strategy. Our analysis of incubator foundings in New York, New Jersey, and Pennsylvania throughout 1980–2004 supports all of these propositions.

The present paper takes a look at the particularities of German strategy research over the last three decades. In contrast to much of the Anglo-Saxon research, which has focused on competition as a guiding concept in theorizing about strategy, German research has typically been concerned with more fundamental questions about the general relationship between organizations and their environments and, as a result, tended to be more conceptual than empirical. Researchers have been particularly influenced by the German sociological and philosophical traditions, specifically by the critical theory of Jürgen Habermas and by the systems theory of Niklas Luhmann. Also, there are authors who draw on the economic tradition of the Austrian School in order to develop a competence-based theory of the firm. Another branch builds on Anthony Giddens's structuration theory and Jacques Derrida's philosophy of deconstruction. As we will demonstrate, much of the research has been concerned with fundamental theoretical tensions: evolution vs. planning, selection vs. compensation, cognitive–instrumental rationality vs. moral–practical rationality, etc. We note that, as a consequence, much of German strategy research shows a particular interest in paradoxa and oxymora (such as ‘planned evolution’, ‘productive misunderstandings’ or ‘unfocused monitoring’). This paper will identify and explore important strands of German strategy research and discuss its particularities compared to mainstream strategy research in the United States.
