Software products

Each software product has a revision number and a date. The user can ask it to the instmment, and save it with the ET data. 

In order to balance public domain science with a high quality commercial software product it has been necessary for us to reimplement almost every aspect of computational chemistry embodied in HyperChem. All HyperChem source code is written in C or C-t-t, specified, designed, and implemented by Hyper-Chem s developers. We have stood on the scientific shoulders of giants, but we have not used their FORTRAN code Thus, although we have had access to MOPAC and other public domain codes for testing and other purposes, HyperChem computes MINDO, MNDO, and AMI wave functions, for example, with HyperChem code, not MOPAC code. We have made the effort to implement modern chemical science in a modern software-engineered product. 

CAS/STlS[Interna.tiona.1. CAS/STN offers stmcture searchable files such as Registry, Beilstein, MARPAT, CASREACT, and Gmelin a variety of learning files, eg, LRegistry, LBeHstein, LMARPAT, and LCASREACT and software products such as STN Express for on-line stmcture and substmcture searching. Chemical Abstracts Service, a division of the American Chemical Society, has pubHshed Chemical Abstracts since 1907 and joindy operates STN International with EIZ Kadsmhe and the Japan Information Center of Science and Technology. 

In this section several free air dispersion software products that can be downloaded from the Web are cited. First, SCREEN can be downloaded from the Butterworth-Heinemann site www.bh.com/companions/0750674997. You can obtain a brief description of the software along with the download, but must mainly rely on the chapter discussions to learn how to use and apply the program.

Other examples are beta tests or public testing conducted on software products where tens or hundreds of products are distributed to designated customer sites for trials under actual operating conditions before product launch. Sometimes, commercial pressures force termination of these trials and products are launched prematurely in order to beat the competition.

Only those sections of 21 CFR Part 11 that describe technical controls required for 21 CFR Part 11 compliance of closed systems are included in this checklist (Table 26.1). Sections that describe only procedural controls [11.10(i), (j), (k) 11.100(b), (c) 11.300(c)] that cannot be implemented by a software product or additional controls for open system (11.30) are not included. Procedural controls can only be exercised during the implementation of a 21 CFR Part 11-compliant system of which the software is a component. 

Other pattern recognition strategies have been used for bacterial identification and data interpretation from mass spectra. Bright et al. have recently developed a software product called MUSE, capable of rapidly speciating bacteria based on matrix-assisted laser desorption ionization time-of-flight mass spectra.13 MUSE constructs a spectral database of representative microbial samples by using single point vectors to consolidate spectra of similar (not identical) microbial strains. Sample unknowns are then compared to this database and MUSE determines the best matches for identification purposes. In a... 

It is indicative of the growing importance of the scientific software market that a major corporation, Bolt Beranek and Newman Inc. (BBN), has recently formed a new business activity called BBN Software Products, focused entirely on developing software for science. BBN Software Products leading software product,... 

Advances in computer science continue to serve as the basis for new extensions to software products. In particular, artificial intelligence techniques have begun to mature to the point at which they can play a role in scientific software. In the future, scientific software will incorporate expert systems technology in order to provide a new level of assistance to scientists in applying statistical and graphical techniques to data analysis. 

The company has extensive processing, analytical and testing laboratory facilities and expertise, and produces a range of engineering and data management software products, and computerised knowledge-based systems. 

The documentation of some software products contain the formulas for gamma densities and distributions, but do not give the connection between the parameters and mean and standard deviation. This connection is made dear by the formula... 

In the independence approach the planning functions are stripped from the old-fashioned ERP system and a modem complete APS system is added as a separate server system with an independent persistent data model and integrated by an interface (Fig. 12.2). Some users of the ERP system also use this separate APS system. This approach is supported, e.g., by the software products SAP APO resp. 

In the embedding approach the ERP system is enhanced with subordinate planning systems that are integrated into the user interface of the ERP system and create a local temporary data storage (LiveCache). All data is still held persistently only in the ERP system (Fig. 12.3). This allows for the LiveCache to use a projection of the ERP data model that is more suitable for APS purposes. This approach is used, e.g., by the software product OR Soft SCHEDULE++. 

These software products are used company-wide and integrate all operational, business and financial information in huge databases. 

Specialized risk consultants and even insurance risk offices can now offer a variety of software products or services to conduct mathematical consequence modeling of most hydrocarbon adverse events. The primarily advantage of these tools is that some estimate can be provided on the possible effects of an explosion or fire incident where previously these effects were rough guesses or unavailable Although these models are effective in providing estimate they still should be used with caution and consideration of other physical features that may alter the real incident outcome. 

Flexibility means the ability not only to change quickly but also to provide several variants at the same time. A bank may deploy the same basic business system globally but needs to be able to adapt it to many localized rules and practices. A software product vendor cannot impose the same solution on every customer nor develop a solution from scratch each time. Instead, software developers prefer to have a configurable family of products. 

The key to making a large variety of software products in a short time is to make one piece of development effort serve for many products. Reuse does not mean that you can cut-and-paste code The proliferation that results, with countless local edits, rapidly becomes an expensive maintenance nightmare. 

The more effective strategy is to make generic designs that are built to be used in a variety of software products. Such reusable assets include code as well as models, design patterns, specifications, and even project plans. 

The formal parts are not necessarily readable on their own by the end users of a software product. But the purpose of formal description is not necessarily to be a contract... 

Some components can be reused more widely than others. Some objects, routines, or patterns might be useful only in several parts of the same software product but if it is a big product or a product family, several teams may need coordinating. 

Therefore, write a specification for each component — whether it is a complete software product, or a group of just a few objects in a larger program. Exceptions can be made for small components, and rapid-assembly products that are not expected to have a long life. 

Bridge the gap between users and developers, without loss of accuracy, when specifying a software product with non-software users. 

For this example, the commercial software products The Unscrambler (Unscrambler 2004) has been used for PLS and MobyDigs (MobyDigs 2004) for GA results have been obtained within few minutes. Some important aspects of multivariate calibration have been mentioned together with this example others have been left out, for instance, full CV is not always a good method to estimate the prediction performance.
