Haiku Deck allows users to create presentations by providing templates and designs for Haiku, a traditional Japanese poetic form. Users can get started making their own Haiku Deck presentation by accessing templates on SlideShare. The document encourages the reader to create their own Haiku Deck presentation.
This document discusses business process management (BPM) and how it relates to service-oriented architecture (SOA). It provides an overview of BPM, including a comparison to business process management systems (BPMS). When choosing a BPMS, the complexity and cost of BPM should be considered. The document also outlines the vision of BPM in enabling flexible modification of process definitions through graphical tools. It notes that while BPM improves agility within a business unit, cross-organizational processes require distributed standards.

The document discusses open data and linked data. It begins by distinguishing between open data, which makes government data available in any format, and linked data, which structures data using URIs, HTTP, RDF vocabularies and standards. It then provides examples of how open data and linked data have been used by initiatives like Data.gov and Data.gov.uk to increase government transparency and enable public participation.
A relay is an electrically operated switch that uses a small current to control a larger current. It was invented in 1835 and works by using an electromagnet to attract or repel a lever, opening or closing the switch contacts. Relays have two positions - normally open or normally closed - depending on the position of the contacts when the coil is not energized. They are commonly used to switch higher voltages or currents than simple solid-state switches can handle and can control multiple circuits at once.
This document provides an overview of the EE2402 Protection & Switchgear course presented by C.Gokul. It includes the course syllabus, units covered, textbook references and introductory content on power system basics, components, faults, protection elements, relay terminology and essential qualities of protection systems. The key topics discussed are types of faults in power systems, importance of protective schemes, elements of a protection system including current transformers, voltage transformers, relays and circuit breakers. Neutral earthing methods with a focus on Peterson coil are also introduced.
This document is a project report on relays by Sheshadri Shekhar Rauth for his Bachelor of Technology degree in Electrical Engineering. It discusses the history and holding capacity of Diesel Loco Shed in Kharagpur, the basic design and operation of relays, and the types of relays used in the shed including wheel slip relays, general purpose relays, and contactor relays. It also provides references and concludes that the training opportunities at the shed were helpful for gaining knowledge about machinery and instruments.
This document provides step-by-step instructions for installing VMware Server 2.0.2 on Windows 7. It details how to access the VMware Infrastructure Web Access interface by entering the URL http://localhost:8222/ or https://hostname:8333. It also explains how to create a new virtual machine, including selecting the guest operating system, storage, and ISO files. Finally, it describes how to access the VMware Server from another client machine using the VMware vSphere Client by entering the server's IP address and port number.
