Federated transaction management (also known as multidatabase transaction management in the literature) is needed to ensure the consistency of data that is distributed across multiple, largely autonomous, and possibly heterogeneous component databases and accessed by both global and local transactions. While the global atomicity of such transactions can be enforced by using a standardized commi...
A flexible, model based fault detection and isolation (FDI) system for an arbitrary configuration of a water tank world has been designed and implemented in MATLAB, SIMULINK and dSPACE. The fault detection is performed with local change detection algorithms, and the fault isolation is performed with residual patterns automatically generated from the total configuration.
The population structure of an organism reflects its evolutionary history and influences its evolutionary trajectory. It constrains the combination of genetic diversity and reveals patterns of past gene flow. Understanding it is a prerequisite for detecting genomic regions under selection, predicting the effect of population disturbances, or modeling gene flow. This paper examines the detailed ...
Local adaptation to different pollinators is considered one of the possible initial stages of ecological speciation as reproductive isolation is a by-product of the divergence in pollination systems. However, pollinator-mediated divergent selection will not necessarily result in complete reproductive isolation, because incipient speciation is often overcome by gene flow. We investigated the pot...
I challenge (1) the assumption that habitat patches are natural units of measurement for species richness, and (2) the assumption of distinct effects of habitat patch size and isolation on species richness. I propose a simpler view of the relationship between habitat distribution and species richness, the ‘habitat amount hypothesis’, and I suggest ways of testing it. The habitat amount hypothes...
Monitoring of the air intake system of an automotive engine is important to meet emission related legislative diagnosis requirements. In this paper, the problem of fault detection in the air intake system is stated as a constraint satisfaction problem over continuous domains with a big number of variables and constraints. This problem can be solved using Consistency Techniques. Consistency tech...
Determining how a new hybrid lineage can achieve reproductive isolation is a key to understanding the process and mechanisms of homoploid hybrid speciation. Here, we evaluated the degree and nature of reproductive isolation between the ecologically successful hybrid species Pinus densata and its parental species P. tabuliformis and P. yunnanensis. We performed interspecific crosses among the th...
The resurgence of tuberculosis (TB) and the emergence of multidrug-resistant TB have resulted in the detention of patients in a number of international jurisdictions since the 1990s, including in Taiwan. The Taiwanese government adopted isolation as an official policy to control TB’s spread in its 2006 Ten-Year Mobilization Plan, whose goal is to halve TB incidence from 66.7 per 100,000 persons...
Biologists seek an understanding of the biological and environmental factors determining local community diversity. Recent advances in metacommunity ecology, and neutral theory in particular, highlight the importance of dispersal processes interacting with the spatial structure of a landscape for generating spatial patterns and maintaining biodiversity. The relative spatial isolation of a commu...
ViZDoom is a robust, first-person shooter reinforcement learning environment, characterized by a significant degree of latent state information. In this paper, double-Q learning and prioritized experience replay methods are tested under a certain ViZDoom combat scenario using a competitive deep recurrent Q-network (DRQN) architecture. In addition, an ensembling technique known as snapshot ensem...
