This paper presents an application monitoring infrastructure developed within the CrossGrid project. The software is aimed at enabling performance measurements for the application developer and in this way facilitating the development of applications in the Grid environment. The application monitoring infrastructure is composed of a distributed monitoring system, the OCM-G, and a performance analysis tool called G-PM. The OCM-G is an on-line, grid-enabled, monitoring system, while G-PM is an advanced graphical tool which allows to evaluate and present the results of performance monitoring, to support optimization of the application execution. G-PM supports build-in standard metrics and user-defined metrics expressed in the Performance Measurement Specification Language (PMSL). Communication between the G-PM and the OCM-G is performed according to a well-defined protocol, OMIS (On-line Monitoring Interface Specification). In this paper, the architecture and features of the OCM-G and G-PM are described as well as an example of use of the monitoring infrastructure to visualize the status and communication in the application, to evaluate the performance, including discovering the reason of the performance flaw.

In today's accessible world, web has turned into a fundamental requirement of everybody. Barring the principal choices of the web, i.e., aquatics and net perusing, we'd like further choices like diversion, on-line video spilling and meeting up and so on. To use entirely unexpected alternatives of the web, very surprising gadgets are offered that changes as far as esteem, figuring force, and show and vitality consumption. Amid this paper, we tend to blessing however entirely unexpected alternatives of the web might be surfed by having one gadget Raspberry Pi. We tend to think about very surprising attributes of Raspberry Pi with in vogue processing gadgets like tablet PC, Smartphones convenient PC and TV. Our outcomes demonstrate that basic registering assignments might be expert in extra vitality practical means. We have a tendency to demonstrate that Raspberry Pi expends less power and may save eminent amount of vitality in routine processing undertakings.

It was discovered in 1970 that certain gas turbine failures are preceded by an increase in electrostatic activity in the exhaust gases. Joint research by the Royal Aerospace Establishment and Stewart Hughes Limited demonstrated that this characteristic could be used to provide an on-line monitor of the precursors to these failures. An extension of the research applied the theory to the detection of foreign objects ingested into engine inlets. The characteristics and performance of both the Ingested Debris Monitoring System (IDMS) and Engine Distress Monitoring System (EDMS) were examined during a recent 2000 hours endurance trial of a Rolls-Royce Marine Spey gas turbine. The EDMS produced clear evidence of the minor combustor degradation that occurred steadily throughout the trial and also reflected the absence of other engine damage. IDMS data showed that few significant debris particles passed through the engine. Video endoscope and visual inspection confirmed these results. Debris seeding trials further explored the capability of the IDMS to identify the damaging nature of debris and to assess the EDMS signature of consequential engine damage. The paper concludes that electrostatic monitoring at engine inlet and exhaust can identify the ingestion of debris, consequential engine damage and the onset of unexpected distresses caused by blade rubs or combustor degradation. The technique shows potential to provide early warning of certain types of engine damage to Engineer Officers at sea and development into a rugged gas path condition monitoring system continues.

This paper introduces the structure of the existing on-line monitoring system, and analyzes the problems of poor compatibility and reliability of IED in different manufacturers. Then it gives two ways to transform the on-line monitoring system of substation equipment to the Internet of things, which is to retain IED and to remove IED. On this basis, this paper introduces the application scenarios of the on-line monitoring system of substation equipment connected to the Internet of things, including accurate perception of equipment status, accurate evaluation of equipment status and intelligent research and judgment of equipment status.
