Event management of large distributed system and network management environments

University of Technology, Sydney. Faculty of Information Technology.Co-ordinated event management across system, network and application environments is a challenging task. The wide diversity of industry and commercial standards, differing business and technical requirements and a huge variety of environments mean there are no simple solutions. This thesis proposes a highly scaleable, flexible and resilient event management architecture that has been applied to the outsourcing activities of HP Services worldwide. Our solution is based on industry standards such as SNMP and commercial products. It provides a framework for all aspects of event management, including event detection, logging, notification, and correlation. It was initially applied and refined in an outsourcing IT environment, then further developed in larger outsourcing environments. It was developed using a standard solution architecture methodology (known as ITSA) that enabled the partly developed architectures to be continually refined, improved and deployed. The technology aspects of the solution work closely with ITIL event management processes. To achieve a unified event display and a standardised event message format, all events from all sources are reduced to a standard format that includes the “raw” event information plus business intelligence, called the business string, added to the event for display and routing purposes. This extra information identifies the nature of the event and allows filtered displays of events. It is extracted from configuration management extensions added to the standard event management tools. The extended format is flexible enough to handle the different commercial tools. The first generation of the solution was based on Computer Associates’ Unicenter TNG and was called the Event Monitoring Utility (EMU). This was later significantly extended by switching to HP OpenView, and the extra development of further central event management functions, especially event correlation, in a solution called DECADE. Significant agent extensions were achieved by the creation and deployment of a solution called SMSPI, which included an extended configuration management and policy database, and further event automation. The extended solution is now deployed across HP Services’ entire global outsourced environment. The solution has proven very successful, winning two Computer Associates Software Achievement Awards, including the Grand Prize, and generating two US patents. It will be progressively deployed to several million servers and network devices globally over the next few years. The work described here is at once self-contained and a basis for on-going development of event management in the face of ever more complex systems, and increasing demands for more detailed event management

Alternative low-cost adsorbent for water and wastewater decontamination derived from eggshellwaste: an overview

As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Recently, various low-cost adsorbents derived from agricultural waste, industrial by-products or natural materials, have been intensively investigated. In this respect, the eggshells from egg-breaking operations constitute significant waste disposal problems for the food industry, so the development of value-added by-products from this waste is to be welcomed. The egg processing industry is very competitive, with low profit margins due to global competition and cheap imports. Additionally, the costs associated with the egg shell disposal (mainly on landfill sites) are significant, and expected to continue increasing as landfill taxes increase. The aim of the present review is to provide an overview on the development of low-cost adsorbents derived from eggshell by-products

Microalgal Biomass of Industrial Interest: Methods of Characterization

International audienceMicroalgae represent a new source of biomass for many applications. The advantage of microalgae over higher plants is their high productivities. The photoautotrophic microalgae include all photosynthetic microorganisms, i.e. Cyanobacteria (prokaryotes) or microalgae (eukaryotes). These microorganisms are characterized by a large biodiversity and chimiodiversity. Then, the analysis of microalgal and cyanobacterial biomass often needs specific adaptations of the classical protocols for extraction as well as for quantification of their contents. This chapter reviewed the main analytical methods used for the analysis of microalgae biomass and its main vaporizable compounds: proteins, polysaccharides, lipids, pigments and secondary metabolites
