The thesis work was carried out in two phases. Firstly, we have designed the Cluster-Based Object Location Services (CBOLS) for finding the object location in a cluster based network topology. Secondly, to take the advantages of clustering architecture of Mobile Ad hoc Networks, we have especially designed Object Location Clusters Algorithm (OLCA) for efficient Object Location management in MAN...

Cities are recognized as a major contributor to environmental pressures. Recently, organizational LCA (OLCA) has been found align well with requirements for city-scale decision support and novel city-OLCA framework was introduced. City-OLCA combines two relevant aspects: It covers activities beyond public service provision (multi-stakeholder) emissions greenhouse gases (multi-impact). Its uniqu...

Ordered latent class analysis (OLCA) can be used to approximate unidimensional latent distributions. The main objective of this study is to evaluate the method of OLCA in detecting non-normality of an unobserved continuous variable (i.e., a common factor) used to explain the covariation between dichotomous item-level responses. Using simulation, we compared a model in which probabilities of cla...

Abstract Purpose Current field emission modelling and toxicity characterisation of pesticides suffer from several shortcomings like mismatches between LCI databases LCIA methods, missing factors, environmental compartments, impact pathways. The OLCA-Pest project was implemented to address these aspects operationalise the assessment in LCA. Based on this effort, we propose an approach integrate ...

In lump coal and gangue separation based on photoelectric technology, the prerequisite of using a dual-energy X-ray to locate identify is obtain independent target area. However, with increase in input sorting system, actual collected images had adhesion overlapping targets. This paper proposes pit point detection segmentation algorithm solve problem The forms are divided into open closed-loop ...

This letter presents a Dynamic Channel Management Scheme (DCMS), using both an One-Layer Cellular Architecture (OLCA) and a Two-Layer Cellular Architecture (TLCA), for use in areas with random offered traffic load. The philosophy of DCMS is that is based either on OLCA or TLCA proposed to the optimization of the handoff blocking probability performance of High-Speed Moving Terminals (HSMT) and ...

A workshop on "New Connections between Mathematics and Computer Science" was held at the Isaac Newton Institute for Mathematical Sciences in Cambridge, England from 20-24 November 1995. The workshop was supported by the Engineering and Physical Science Research Council of the United Kingdom, the London Mathematical Society and Hewlett-Packard's Basic Research Institute in the Mathematical Scien...
