Project Abstract - Hospital Management System

A hospital information system (HIS), variously also called clinical information system (CIS) is a comprehensive, integrated information system designed to manage the administrative, financial and clinical aspects of a hospital. This encompasses paper-based information processing as well as data processing machines.

It can be composed of one or a few software components with specialty-specific extensions as well as of a large variety of sub-systems in medical specialties (e.g. Laboratory Information System, Radiology Information System).

CISs are sometimes separated from HISs in that the former concentrate on patient-related and clinical-state-related data (electronic patient record) whereas the latter keeps track of administrative issues. The distinction is not always clear and there is contradictory evidence against a consistent use of both terms.

How to make a Presentation

Below are some of the ways to prepare for presentation/seminars

Think about the presentation beforehand. It is short-changing the organisers of the event and your audience if you only think about what you're going to say the day before or while travelling to the event. If necessary, clarify with the organisers exactly what is required of you and what facilities you will require.

Do use PowerPoint if the facilities are available. Although some speakers seem to have taken an aversion to PowerPoint, it is so convenient and ensures that your presentation has a clear structure and something for your listeners to take away.

Be very clear about how much time you have - and stick to that time in preparing and delivering your presentation. It's very difficult to 'cut' a PowerPoint presentation at the event itself, so it's a great mistake to run out of time. Most presenters prepare too much material; but nobody ever complains that a presentation was too short (it always allows more time for questions).

Be very clear about your key message - and ensure that everything in your presentation is both consistent with, and suppportive of, that key message. You should be able to articulate the message in a phrase or a sentence and indeed you might want to use that phrase or sentence in one of your first slides, or one of your last, or even both.

Seminar on Project management

Project management is the discipline of planning, organizing, securing and managing resources to bring about the successful completion of specific project goals and objectives.

A project is a temporary endeavor, having a defined beginning and end (usually constrained by date, but can be by funding or deliverables), undertaken to meet unique goals and objectives, usually to bring about beneficial change or added value. The temporary nature of projects stands in contrast to business as usual (or operations), which are repetitive, permanent or semi-permanent functional work to produce products or services. In practice, the management of these two systems is often found to be quite different, and as such requires the development of distinct technical skills and the adoption of separate management.

The primary challenge of project management is to achieve all of the project goals and objectives while honoring the preconceived project constraints. Typical constraints are scope, time, and budget. The secondary—and more ambitious—challenge is to optimize the allocation and integration of inputs necessary to meet pre-defined objectives.

Seminar on Linux Virtual File System

A virtual file system (VFS) or virtual filesystem switch is an abstraction layer on top of a more concrete file system. The purpose of a VFS is to allow client applications to access different types of concrete file systems in a uniform way. A VFS can, for example, be used to access local and network storage devices transparently without the client application noticing the difference. It can be used to bridge the differences in Windows, Mac OS and Unix filesystems, so that applications can access files on local file systems of those types without having to know what type of file system they are accessing.

A VFS specifies an interface (or a "contract") between the kernel and a concrete file system. Therefore, it is easy to add support for new file system types to the kernel simply by fulfilling the contract. The terms of the contract might change incompatibly from release to release, which would require that concrete file system support be recompiled, and possibly modified before recompilation, to allow it to work with a new release of the operating system; or the supplier of the operating system might make only backward-compatible changes to the contract, so that concrete file system support built for a given release of the operating system would work with future versions of the operating system.

Internet Marketing Strategy

Developing a successful internet marketing strategy is an essential part of your online success. In order to succeed, you must develop and implement a strategic plan that includes all of the following:
• A great product
• A web site specifically designed to sell
• A killer marketing strategy
Each step plays an important role in your overall strategy and must be developed to its fullest potential. If even one step fails, your chances of success will be minimal.

Developing Your Product

Your first step will be to develop a great product. You're probably thinking that's easier said than done, but it's really not. The absolute best product is one that you can develop yourself and deliver over the Internet. With today's technology, there is absolutely no reason why you can't create your own product. The knowledge you have within your own mind is extremely valuable. Everybody is good at something, has a special talent or some specialized knowledge. Use this knowledge to create a product.
The key to developing a great product is exclusiveness. Your product should be unique and not be in competition with hundreds of other similar products. You must give your potential customers exactly what they want. Develop a high-quality product that fills a void to increase your chance of success.
Another consideration of great importance is your target market. Keep in mind, the Internet is a global marketplace. Develop a product with a large geographic target and a wide appeal. A great product will fulfill a need or desire and provide instant gratification.

Seminar on Internet Marketing

Internet marketing, also known as digital marketing, web marketing, online marketing, search marketing or e-marketing, is the marketing (generally promotion) of products or services over the Internet.

Internet marketing is considered to be broad in scope because it not only refers to marketing on the Internet, but also includes marketing done via e-mail and wireless media.Digital customer data and electronic customer relationship management (ECRM) systems are also often grouped together under internet marketing.

Internet marketing ties together the creative and technical aspects of the Internet, including design, development, advertising, and sales. Internet marketing also refers to the placement of media along many different stages of the customer engagement cycle through search engine marketing (SEM), search engine optimization (SEO), banner ads on specific websites, email marketing, and Web 2.0 strategies.[citation needed]

In 2008, The New York Times, working with comScore, published an initial estimate to quantify the user data collected by large Internet-based companies. Counting four types of interactions with company websites in addition to the hits from advertisements served from advertising networks, the authors found that the potential for collecting data was up to 2,500 times per user per month.

Ebook Search Engine Optimization Starter Guide

Welcome to Google's Search Engine Optimization Starter Guide. This document first began as an
effort to help teams within Google, but we thought it'd be just as useful to webmasters that are new to
the topic of search engine optimization and wish to improve their sites' interaction with both users and
search engines. Although this guide won't tell you any secrets that'll automatically rank your site first
for queries in Google (sorry!), following the best practices outlined below will make it easier for search
engines to both crawl and index your content.

Search engine optimization is often about making small modifications to parts of your website. When
viewed individually, these changes might seem like incremental improvements, but when combined

with other optimizations, they could have a noticeable impact on your site's user experience and
performance in organic search results. You're likely already familiar with many of the topics in this
guide, because they're essential ingredients for any webpage, but you may not be making the most
out of them.

Even though this guide's title contains the words "search engine", we'd like to say that you should
base your optimization decisions first and foremost on what's best for the visitors of your site. They're
the main consumers of your content and are using search engines to find your work. Focusing too
hard on specific tweaks to gain ranking in the organic results of search engines may not deliver the
desired results. Search engine optimization is about putting your site's best foot forward when it
comes to visibility in search engines.

Seminar on Search Engine Marketing

Search engine marketing, (SEM), is a form of Internet marketing that seeks to promote websites by increasing their visibility in search engine result pages (SERPs) through the use of, paid placement, contextual advertising, and paid inclusion. Search engine optimization (SEO) is "optimizing" website pages to achieve higher ranking in search results via the process of selecting specific keyword expressions associated to the website SEM is utilizing various means of "marketing" a website in order for it to become more relevant in regard to search engine searches and their rankings. It should be asserted that SEM is NOT SEO and vice versa. SEM constitutes Ad words which comprises pay per call (particularly beneficial for local providers as it enables potential consumers to get in touch directly to a company with one click), article submissions, advertising and making sure SEO has been done. Also, key word analysis needs to be done for both SEO and SEM; but not necessarily at the same time. SEM is a constant and tedious task. It frequently needs to be updated and monitored continually. Another part of SEM is Social Media Marketing (SMM). SMM is a type of marketing that involves exploiting social media to influence consumers that one company’s products and/or services are valuable. You can do SEM without doing SMM but you can't do SMM without doing SEM because SMM is a higher level of SEM.

As the number of sites on the Web increased in the mid-to-late 90s, search engines started appearing to help people find information quickly. Search engines developed business models to finance their services, such as pay per click programs offered by Open Text in 1996 and then Goto.comin 1998. Goto.com later changed its name to Overture in 2001, and was purchased by Yahoo! in 2003, and now offers paid search opportunities for advertisers through Yahoo! Search Marketing. Google also began to offer advertisements on search results pages in 2000 through the Google AdWords program. By 2007, pay-per-click programs proved to be primary money-makers for search engines. In a market dominated by Google, in 2009 Yahoo! and Microsoft announced the intention to forge an alliance. The Yahoo! & Microsoft Search Alliance eventually received approval from regulators in the US and Europe in February 2010

Ebook - Java™ Application Development on Linux

Why another book on Java? Why a book on Java and Linux? Isn’t Java a platform-independent system? Aren’t there enough books on Java? Can’t I learn everything I need to know from the Web?
No doubt, there are a host of Java books on the market. We didn’t wake up one morning and say, “You know what the world really needs? Another book about Java!” No. What we realized was that there are a couple of “holes” in the Java book market.
First, Linux as a development platform and deployment platform for Java applications has been largely ignored. This is despite the fact that the *nix platform (meaning all UNIX and UNIX-like systems, Linux included) has long been recognized as one of the most programmer-friendly platforms in existence.

Those few resources for Java on Linux that exist emphasize tools to the exclusion of the Java language and APIs.
Second, books on the Java language and APIs have focused on pedagogical examples that serve to illustrate the details of the language and its libraries, but very few of these examples are in themselves practically useful, and they tend to deal only with the issues of writing programs, and not at all with deploying and maintaining them. Anyone who has worked on a major software project, especially a software project that is developed and deployed in a business for a business, knows that designing and coding are only about half of the work involved. Yes, writing Java code is only slightly affected by the development and the deployment platform, but the process of releasing and maintaining such applications is significantly different between platforms.

Seminar on Java Security

Java's security model is one of the language's key architectural features that makes it an appropriate technology for networked environments. Security is important because networks provide a potential avenue of attack to any computer hooked to them. This concern becomes especially strong in an environment in which software is downloaded across the network and executed locally, as is done with Java applets, for example. Because the class files for an applet are automatically downloaded when a user goes to the containing Web page in a browser, it is likely that a user will encounter applets from untrusted sources. Without any security, this would be a convenient way to spread viruses. Thus, Java's security mechanisms help make Java suitable for networks because they establish a needed trust in the safety of network-mobile code.

Java's security model is focused on protecting users from hostile programs downloaded from untrusted sources across a network. To accomplish this goal, Java provides a customizable "sandbox" in which Java programs run. A Java program must play only inside its sandbox. It can do anything within the boundaries of its sandbox, but it can't take any action outside those boundaries. The sandbox for untrusted Java applets, for example, prohibits many activities, including:

Reading or writing to the local disk
Making a network connection to any host, except the host from which the applet came
Creating a new process
Loading a new dynamic library and directly calling a native method

By making it impossible for downloaded code to perform certain actions, Java's security model protects the user from the threat of hostile code.

Web Services in Java

Web services are Web based applications that use open, XML-based standards and transport protocols to exchange data with clients. Web services are developed using Java Technology APIs and tools provided by an integrated Web Services Stack called Metro.

The Metro stack consisting of JAX-WS, JAXB, and WSIT, enable you to create and deploy secure, reliable, transactional, interoperable Web services and clients. The Metro stack is part of Project Metro and as part of GlassFish, Java Platform, Enterprise Edition (Java EE), and partially in Java PlatForm, Standard Edition (Java SE). GlassFish and Java EE also support the legacy JAX-RPC APIs.

Grid network

A grid network is a kind of computer network consisting of a number of (computer) systems connected in a grid topology.

In a regular grid topology, each node in the network is connected with two neighbors along one or more dimensions. If the network is one-dimensional, and the chain of nodes is connected to form a circular loop, the resulting topology is known as a ring. Network systems such as FDDI use two counter-rotating token-passing rings to achieve high reliability and performance. In general, when an n-dimensional grid network is connected circularly in more than one dimension, the resulting network topology is a torus, and the network is called "toroidal". When the number of nodes along each dimension of a toroidal network is 2, the resulting network is called a hypercube.

A parallel computing cluster or multi-core processor is often connected in regular interconnection network such as a de Bruijn graph , a hypercube graph, a hypertree network, a fat tree network, a torus, or cube-connected cycles.

Note that a grid network is not the same as a grid computer (or computational grid) (even though the nodes in a grid network are usually computers, and grid computing obviously requires some kind of computer network to interconnect the computers)

Earth Simulator

The Earth Simulator (ES), developed by the Japanese government's initiative "Earth Simulator Project", was a highly parallel vector supercomputer system for running global climate models to evaluate the effects of global warming and problems in solid earth geophysics. The system was developed for Japan Aerospace Exploration Agency, Japan Atomic Energy Research Institute, and Japan Marine Science and Technology Center in 1997. Construction started in October 1999, and the site officially opened on March 11, 2002. The project cost 60 billion yen.

Built by NEC, ES was based on their SX-6 architecture. It consisted of 640 nodes with eight vector processors and 16 gibibytes of computer memory at each node, for a total of 5120 processors and 10 terabytes of memory. Two nodes were installed per 1 metre x 1.4 metre x 2 metre cabinet. Each cabinet consumed 20 kW of power. The system had 700 terabytes of disk storage (450 for the system and 250 for the users) and 1.6 petabytes of mass storage in tape drives. It was able to run holistic simulations of global climate in both the atmosphere and the oceans down to a resolution of 10 km. Its performance on the LINPACK benchmark was 35.86 TFLOPS, which was almost five times faster than ASCI White.

Socket Programming

Sockets are interfaces that can "plug into" each other over a network. Once so "plugged in", the programs so connected communicate. A "server" program is exposed via a socket connected to a certain /etc/services port number. A "client" program can then connect its own socket to the server's socket, at which time the client program's writes to the socket are read as stdin to the server program, and stdout from the server program are read from the client's socket reads.

Before a user process can perform I/O operations, it calls Open to specify and obtain permissions for the file or device to be used. Once an object has been opened, the user process makes one or more calls to Read or Write data. Read reads data from the object and transfers it to the user process, while Write transfers data from the user process to the object. After all transfer operations are complete, the user process calls Close to inform the operating system that it has finished using that object.

WI-MAX

WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile internet access. The technology provides up to 10 Mbps broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called Broadband Wireless Access). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL".

WISENET

WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called "motes" that form an ad-hoc network to transmit this data to a computer that function as a server. The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote.

Introduction:
The technological drive for smaller devices using less power with greater functionality has created new potential applications in the sensor and data acquisition sectors. Low-power microcontrollers with RF transceivers and various digital and analog sensors allow a wireless, battery-operated network of sensor modules ("motes") to acquire a wide range of data. The TinyOS is a real-time operating system to address the priorities of such a sensor network using low power, hard real-time constraints, and robust communications.

The first goal of WISENET is to create a new hardware platform to take advantage of newer microcontrollers with greater functionality and more features. This involves selecting the hardware, designing the motes, and porting TinyOS. Once the platform is completed and TinyOS was ported to it, the next stage is to use this platform to create a small-scale system of wireless networked sensors.

System Description:
There are two primary subsystems (Data Analysis and Data Acquisition) comprised of three major components (Client, Server, Sensor Mote Network).
Primary Subsystems:
There are two top-level subsystems -
Data Analysis
Data Acquisition.

Data Analysis:
This subsystem is software-only (relative to WISENET). It relied on existing Internet and web (HTTP) infrastructure to provide communications between the Client and Server components. The focus of this subsystem was to selectively present the collected environmental data to the end user in a graphical manner.

Optical fiber communication

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. First developed in the 1970s, fiber-optic communication systems have revolutionized the telecommunications industry and have played a major role in the advent of the Information Age. Because of its advantages over electrical transmission, optical fibers have largely replaced copper wire communications in core networks in the developed world.

The process of communicating using fiber-optics involves the following basic steps: Creating the optical signal involving the use of a transmitter, relaying the signal along the fiber, ensuring that the signal does not become too distorted or weak, receiving the optical signal, and converting it into an electrical signal.

Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Due to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in long-distance and high-demand applications. However, infrastructure development within cities was relatively difficult and time-consuming, and fiber-optic systems were complex and expensive to install and operate. Due to these difficulties, fiber-optic communication systems have primarily been installed in long-distance applications, where they can be used to their full transmission capacity, offsetting the increased cost. Since 2000, the prices for fiber-optic communications have dropped considerably. The price for rolling out fiber to the home has currently become more cost-effective than that of rolling out a copper based network. Prices have dropped to $850 per subscriber in the US and lower in countries like The Netherlands, where digging costs are low.

Since 1990, when optical-amplification systems became commercially available, the telecommunications industry has laid a vast network of intercity and transoceanic fiber communication lines. By 2002, an intercontinental network of 250,000 km of submarine communications cable with a capacity of 2.56 Tb/s was completed, and although specific network capacities are privileged information, telecommunications investment reports indicate that network capacity has increased dramatically since 2004.

Lightweight Directory Access Protocol

The Lightweight Directory Access Protocol, or LDAP ,is an application protocol for querying and modifying directory services running over TCP/IP.

A directory is a set of objects with attributes organized in a logical and hierarchical manner. A simple example is the telephone directory, which consists of a list of names (of either persons or organizations) organized alphabetically, with each name having an address and phone number associated with it.

An LDAP directory tree often reflects various political, geographic, and/or organizational boundaries, depending on the model chosen. LDAP deployments today tend to use Domain Name System (DNS) names for structuring the topmost levels of the hierarchy. Deeper inside the directory might appear entries representing people, organizational units, printers, documents, groups of people or anything else that represents a given tree entry (or multiple entries).

Its current version is LDAPv3, which is specified in a series of Internet Engineering Task Force (IETF) Standard Track Requests for comments (RFCs) as detailed in RFC 4510

A client starts an LDAP session by connecting to an LDAP server, called a Directory System Agent (DSA), by default on TCP port 389. The client then sends an operation request to the server, and the server sends responses in return. With some exceptions, the client does not need to wait for a response before sending the next request, and the server may send the responses in any order.

The client may request the following operations:

    * Start TLS — use the LDAPv3 Transport Layer Security (TLS) extension for a secure connection
    * Bind — authenticate and specify LDAP protocol version
    * Search — search for and/or retrieve directory entries
    * Compare — test if a named entry contains a given attribute value
    * Add a new entry
    * Delete an entry
    * Modify an entry
    * Modify Distinguished Name (DN) — move or rename an entry
    * Abandon — abort a previous request
    * Extended Operation — generic operation used to define other operations
    * Unbind — close the connection (not the inverse of Bind)
