of feedbacks, one caused by "cycles " of material flow in non-acyclic manufacturing systems, and the other introduced by the employment of closed-loop scheduling algorithms. We examine the consequences of this interaction for the stability properties of the manufacturing system in terms

Given a checkpoint and communication pattern of a distributed execution, the "No Z-Cycle" property (NZC) states that there does not exist a dependency between a checkpoint and itself. In other words,

Dynamic code generation is the creation of executable code at runtime. Such “on-the-fly ” code generation is a powerful technique, enabling applications to use runtime information to improve performance by up to an order of magnitude [4, 8, 20, 22, 23]. Unfortunately, previous general

engineering. It replaces/subsumes the technological paradigm of the Industrial Age, organized primarily around the production and distribution of energy. In this article I aim at clarifying the theoretical implications that can be induced from my observation of contemporary social structures and social change

cages (with HEPA air filters) in the AAALAC-accredited vivarium at the Johnson Space Center (JSC). Animals were allowed to acclimate at this facility (with a 12-h light-dark cycle) for at least one week before being used in the study. The mice had free access to tap water and Purina Formulab Chow No

(MMOGs) can include millions of concurrent players spread across the world and interacting with each other within a single session. Faced with high resource demand variability and with misfit resource renting policies, the current industry practice is to over-provision for each game tens of self-owned data centres, making the market entry affordable only for big companies. Focusing on the reduction of entry and operational costs, we investigate a new dynamic resource provisioning method for MMOG operation using external data centres as low-cost resource providers. First, we identify in the various types of player interaction a source of short-term load variability, which complements the long-term load variability due to the size of the player population. Then, we introduce a combined MMOG processor, network, and memory load model that takes into account both the player interaction type and the population

. We start by examining consensus, a classic problem in distributed systems, and then proceed to study various specifications and implementations of eventually consistent systems. As more and more developers write programs that execute on a virtualized cloud infrastructure, they find themselves
