Causal message logging is an efficient approach for tolerating failures of processes in distributed systems because it has the advantages of both pessimistic and optimistic message logging approach. However, traditional causal message logging protocols prevent live processes from executing continuously their computation and require some synchronous logging to the stable storage during recovery....

We propose a framework with endogenous allocation of land between agricultural production, sustainable forest management, and unsustainable forest exploitation in the form of illegal logging to explore deforestation and agricultural and timber supplies when property rights are insecure. Uncertainty over property rights arises through risk of confiscation on sustainably-managed forest land, and ...

VANCLAY, J.K. 1989. Modelling selection harvesting in tropical rain forests. Long term yield estimates for natural forests require a harvesting model to enable future yields to be estimated reliably. The model should predict the felled stems, the proportion of these which are merchantable, and any damage to the residual stand. Regression analyses was used to develop a model of current logging p...

In this paper, we present two fault-tolerant protocols for mobile computing systems; a causal message logging protocol and a receiver-based pessimistic message logging protocol for tolerating failures of mobile hosts (MHs) and mobile support stations (MSSs) respectively. The systems raise several constraints such as limited life of battery power, mobility and disconnection of hosts and lack of ...

The time required for recovery from a failure is heavily influenced by hardware setup and workload characteristics. In bad but still realistic cases, the recovery required during restart can take hours. For a database system based on write-ahead logging, we performed a qualitative study of how hardware and software configurations affect the behavior of the database and, consequently, how this b...

We simulate electromagnetic (EM) measurements acquired with a logging-while-drilling (LWD) instrument in a borehole environment. The measurements are used to assess electrical properties of rock formations. Logging instruments as well as rock formation properties are assumed to exhibit axial symmetry around the axis of a vertical borehole. The simulations are performed with a self-adaptive goal...

In this position paper, we propose to investigate novel technologies for evaluating information visualization systems: physiological sensing. We review existing technologies and describe how advances in physiological sensing open a novel perspective for the evaluation of information visualization systems.
