Also a very important the instrument may be adapted to a customer s needs by only changing software, and handing a floppy disk to the customer. Even better, the customer himself can download the software from our server, using a modem or the Internet. 

Information on CEN/TC138/AHG3, such as the draft document, the minutes of meetings, the list of references and the members addresses, may be obtained on Internet on the BAM server at http //trappist.kb,bam-berlin.de/CEN/cenalig3.html. 

On NDTnet both retrieval methods are optimally combined, however that is only successfully because the content on the server is extensive and valuable (Table 2). A full text search with all advanced search features is available and the site also provides a table of contents for each month and archives are organized in subjects together with an alphabetical index. 

Opinions differ widely on the subject of corporate websites. You can currently buy server disc space for HTML pages for a mere 5 US, or many providers include it with the basic account The main disadvantages are related to server functions, bandwidth and other offered services. 

Alternatively, those at the other end of the market speak proudly of their own exclusive server But the true financial costs of this can range from US 30-100 thousand annually. Costs increase (rapidly) with the sophistication of functions offered. On the other hand, increased function is the reason for buying a server ... 

A suggested middle ground is a quality server provider who can deliver the features you need Load your pages on the Server and get your own domain, "www.eompany.com", that means you operate a virtual server Your presence is then quick and inexpensive to achieve. You also remain flexible and independent, so can always transfer to another server if you decide to change providers for any reason.

Edcfy-cufrent NDT inspections using spatial data (sampled scans) ha >e many benefits. They separate the two conflicting aspects of an inspection scanning and signal interpretation. An instrument/display (client/server) based NDT inspection based on sampled scan data aides in the training and certification of inspectors. It can be used over the Internet or in-house Intranet networks to train or examine inspectors at multiple or remote sites. This saves travel time and resources as defects, instrumentation and teaching can all be consolidated Samples can be maintained and distributed from a central certification body providing more control andflexibility. 

A major benefit of sampled data is the ability to store it. Once this data has been stored it can be analyzed, plotted and used in a simulator. A simulator reinstates the client/server paradigm, allowing the user to re-experience the inspection, synchronously. Different data filters and mappings can be used. For example, in Figure 4, a simple mapping... 

The instrument/display (client/server) paradigm allows for synchronous and asynchronous analysis, locally or remotely via the Internet or in-house Intranet network. 

When the button "submit smiles is pressed, the SMILES string is sent to the web server of Molsoft, converted to 3D, and the 3D structure is displayed in a java molecule viewer on an automatically created web page (see Figure 2-139). Unfortunately, the Molsoft server does not support downloading of the 3D structures in a standard file format. 

A hands-on experience with the method is possible via the SPINUS web service [48. This service uses a client-server model. The user can draw a molecular structure within the web browser workspace (the client), and send it to a server where the predictions are computed by neural networks. The results are then sent back to the user in a few seconds and visualised with the same web browser. Several operations and different types of technology arc involved in the system ... 

The molecular editor consists of a java applet that is embedded in the HTML document. It encodes the drawing into a connection table in inol-format, which is sent to the web server. 

The importance of this information on biochemical reactions is emphasized by the fact that an image of the poster is also accessible on the ExPASy seiwer [20]. However, for this purpose, the poster has only been scanned. The ExPASy server provides a static image of the information on this web site, augmented only by links to additional information. 

A back end program essentially acts as a computational server for the front end. It receivcsinpiit, computes something, sendsit back to the front end and then looks for further input or commands from the front end. It can be used over and over for different cal-cii lation s. If it has been explicitly stopped, the Iron t end will start... 

The in ternal arch itecture of HyperChem back ends is different from that expected to be used by third-party packages. To a third-party agent wishing to interface with HyperChem, HyperChem always acts as a server. Thus a third-party molecular dynamics package w oiild ask HyperChem to send th e coordinates of a mide-cu le rath cr th an HvperCIhem determ in in g on its own that it should send coordinates at the appropriate time. 

UniChem (we tested Version 4.1) is a graphic interface made for running calculations on remote machines. The UniChem GUI runs on the local workstation and submits the computations to be run on a remote machine. The server software comes with MNDO, DGauss, and CADPAC. It can also be used as a graphic interface for Gaussian and Q-Chem. A toolkit can be purchased separately, which allows users to create an interface to their own programs. 

The calculation setup screens list a good selection of the options that are most widely used. However, it is not a complete list. The user also chooses which queue to use on the remote machine and can set queue resource limits. All of this is turned into a script with queue commands and the job input file. The user can edit this script manually before it is run. Once the job is submitted, the inputs are transferred to the server machine, the job is run and the results can be sent back to the local machine. The server can be configured to work with an NQS queue system. The system administrator and users have a reasonable amount of control in configuring how the jobs are run and where files are stored. The administrator should look carefully at this configuration and must consider where results will be sent in the case of a failed job or network outage. 

The functionality available in MedChem Explorer is broken down into a list of available computational experiments, including activity prediction, align/ pharmacophore, overlay molecules, conformer generation, property calculation, and database access. Within each experiment, the Web system walks the user through a series of questions that must be answered sequentially. The task is then submitted to a remote server, where it is performed. The user can view the progress of the work in their Web browser at any time. Once complete, the results of the calculation are stored on the server. The user can then run subsequent experiments starting with those results. The Web interface includes links to help pages at every step of the process. 

Activity prediction is based on a list of models (i.e., QSAR models, pharmacophore models, etc.) that are maintained on the server. There is a second level of access so that only authorized users may be allowed to add or delete model entries. 

Encyclopedia of Computational Chemistry John Wiley Sons, New York (1998). Some software packages are mentioned in sequence in this encyclopedia and others are collected at the end of volume 5. http //server.ccl.net/... 

This book grew out of a collection of technical-support web pages. Those pages were also posted to the computational chemistry list server maintained by the Ohio Supercomputer Center. Many useful comments came from the subscribers of that list. In addition, thanks go to Dr. James F. Harrison at Michigan State University for providing advice born of experience. 

The three basic Internet appHcations of remote login, electronic mad, and file transfer are also budding blocks of more sophisticated appHcations that offer increased functionaUty and ease of network use. Tools such as Gopher, Wide Area Information Servers (WAIS), and World Wide Web (WWW) go beyond the three basic Internet functions to make information on the network easier to locate and use. Detaded descriptions of these tools are avadable (10). This trend toward more powerful, user-friendly networked information resource access systems should continue as Internet grows and matures. 

A significant concept of the chent/server model is to extend the scope of the apphcation to function ia an enterprise-wide (possibly worldwide) network of iaterconnected LANs, which allow LIMS and other apphcations foUowiag the chent/server model to be operable and administrable on a much larger scale than either LAN or central processiag models. 

The cheat/server model oftea allows easier iategratioa with other aetwork apphcatioas (eg, fiaance, project management, or human resources) which typically operate ia the environment of the server component of the cheat/server system. Gheat/server can be gradually iatroduced ia an existing minicomputer environment, often with httie adverse incremental impact ia terms of retraining and additional cost. 

For these reasons, the desktop and chent/server models are expected to increase in percentage of LIMS software offerings and installed base in the...
