We demonstrated a flexible Genome-Wide Association Study (GWAS) platform built upon the iPlant Collaborative Cyber-infrastructure. The platform supports big data management, sharing, and large scale study of both genotype and phenotype data on clusters. End users can add their own analysis tools, and create customized analysis workflows through the graphical user interfaces in both iPlant Disco...

Spatial Objects Models are the foundation stone of GIS. With increasing awareness and acceptance of spatial data uncertainty, how to model the fuzzy spatial objects is one of the important issues. This paper proposes a flexible fuzzy spatial objects model in practice in the eyes of design patterns. Also, as an instance, we will show how to use the model to predicate the topological relations be...

FIPA (Foundation for Intelligent Physical Agents) is a standardisation organisation promoting development and specification of agent technologies. Until now FIPA specifications have not been considering mobile ad hoc networks. In such environments agents depend on flexible discovery mechanisms to take advantage of services provided by other agents. This paper describes the major steps that led ...

A GREAT DEAL OF UNCERTAINTY exists regarding the effectiveness of safety incentive programs in construction. Most research on incentives involves case studies and theoretical analyses of their advantages and disadvantages. Using primary survey data from construction firms and craftworkers, this article examines the impact of incentives on the safety performance of U.S. construction firms. The s...

The objective of this study is to investigate the combustion in a pilot-ignited supercharged dual-fuel engine, fueled with different types of gaseous fuels under various equivalence ratios. It is found that if certain operating conditions are maintained, conventional dual-fuel engine combustion mode can be transformed to the combustion mode with the two-stage heat release. This mode of combusti...

cooperative object manipulation control of rigid-flexible multi-body systems in space is studied in this paper. during such tasks, flexible members like solar panels may get vibrated that in turn may lead to some oscillatory disturbing forces on other subsystems, and consequently produces error in the motion of the end-effectors of the cooperative manipulating arms. therefore, to design and dev...

The response of pile groups and piled structures to vertical tunnelling-induced loads is studied. A two-stage model adopted that can efficiently consider external actions, greenfield tunnelling movements, superstructure stiffness, ultimate shaft base stresses, pile-soil interactions in uniform or layered soils, local soil behaviour (as either linear elastic, elastic perfectly-plastic, nonlinear...

data envelopment analysis (dea) has been proven as an efficient technique to evaluate the performance of homogeneous decision making units (dmus) where multiple inputs and outputs exist. in the conventional applications of dea, the data are considered as specific numerical values with explicit designation of being an input or output. however, the observed values of the data are sometimes imprec...
