Software models

It is essential that, with the use of evidence-based medicine to inform decisions in health care, the processes used in program development be as transparent as possible. Information about the limited evidence and inherent uncertainty should be disclosed and available for scrutiny, even within the software itself. In fact, in an attempt to maximize transparency, some have advocated open source development and publication of interactive software models [49, 50]. Certainly, details of methodologies, sources, and other techniques employed for development of the underlying models must be acknowledged. However, the proprietary nature of many of these programs must be taken into consideration and measures put into place to ensure confidentiality. Requested publication of all NIH-sponsored research online (in PubMed) [51] within a reasonable time frame after journal acceptance will help to ensure that these data are available in the public domain in short order. 

Any software model of the brain that we could create using a current PC could emulate only an infinitesimal amount of it, so it might seem that our expectations of what an ANN could accomplish should be set at a thoroughly modest level. Happily, the reality is different. Though computer-based neural networks are minute compared with the brain, they can still outperform the brain in solving many types of problems. 

If the available computational models are insufficiently detailed so that behavior is too uncertain to predict, or if the only model that can be constructed is so detailed that its execution is unacceptably slow, we cannot expect to be able to use an expert system to control the process under all circumstances. Fortunately, there is an alternative — a software model that can learn how to control a system rather than needing to be told how to do so. 

This software model is a learning classifier system. Because classifier systems learn, they can be applied to the control of a dynamic system, such as a reactor or an instrument, which must process various types of samples under unpredictable conditions, even when the rules required for successful control are unknown.

In reality, the interaction of chelants with metal ions is determined by a variety of factors pH, temperature, concentration of chelant, and concentration of all metal ions present in the system. The calculations are not simple and are best done by speciation software models, a number of which are available [31]. 

The technique is easy and fast to use, involving only cell harvesting, washing and drying of the biomass on an IR-transparent carrier as sample preparation, before the spectra are recorded and evaluated. An instrument dedicated for organism identification is available and has been used for the cited process monitoring experiments with complete spectrometer hardware and software, model IFS 28/B from Bruker (Milton, ON, Canada or Bruker Optik, Karlsruhe, Germany). The whole procedure takes less than an hour.

The Software Design of the project covers system and application software required to fulfill the project. System software models depend on the choice of hardware. Table 25.5 identifies a range of options for software required for implementing IPC applications. 

New pocket portals, using WAP or Blue Tooth technology, is also becoming an attractive option. However, a cautionary note needs to be registered with the heightened importance of system security and the risks of transmitting data over open systems. Biometrics and encryption are potential solutions. Also, audit trails need to be consistent across the range of software models adopted, especially client-server architectures and hand-held IPCs.

White Carbon offers a software platform named Pathways that targets the development of workflows for discovery procedures in the laboratory (not to be confused with the more recent application of the term to biochemical pathways in the systems biology sense). A user of the software develops and refines a model that captures a best practice and may then deploy that model for the benefit of a wider discovery community. The software also provides a basis for the use of lab equipment to automate appropriate tasks within the workflow. The procedures that the software models generally relate to laboratory activities, but may also include interaction with other software tools or data repositories. 

Simulation models are computer programs that mimic the behavior of a system as transactions flow through the various simulated resources. Simulation involves actually building a software model of... 

LCA includes the following important steps materials extraction, manufacturing and waste production, packaging, transportation, product use and product disposal. In order to calculate the amount of emissions and waste created during the life cycle of a product, much fundamental information is needed on manufacturing processes, materials and energy use. A life cycle inventory (LCI) is therefore compiled to record the emissions and resources consumed that can be attributed to a specific product. Databases have been developed that enable the user to input new information or data specific to their products and processes. Ecoinvent v3 (http //www.ecoinvent. org/database/) is probably the most comprehensive international LCI database. The ecoinvent database is included in most LCA software models. The following are some of the software suitable for LCA of plastics (O Neill, 2003) ... 

Software solutions. Companies no longer want to buy license software. The evolution of software as a service (SaaS) and iTUnes concepts are shifting purchasing behavior. The shift is from a large purchase (license software model) to one of rental (incremental payments based on usage). This shift in the sale of enterprise software also redefines the customer relationship to drive higher levels of satisfaction and customer value. 

It is also good practice to compare the statistical forecast to a naive forecast. (The naive forecast is a simple technique where the forecast equals the volume of goods sold in the prior forecasting period.) Naive forecasts, in some situations, can be surprisingly difficult to beat, yet it is very important that the organizations ensure that software and a statistical modeler improve on the naive model. The focus needs to be on continuous improvement. If the software, modeler is not able to do this, it makes sense to implement better software, improve the skills of the modeler, or just use the naive model as a baseline forecast.

State-based models describe the software using Markov chains (Ross 2000 Lyu 1995). Markov chains are stochastic processes Y(t) / > 0 where W(t) denotes state at time t. With respect to component-based software models (Lyu 1995) states may in the simpler cases refer only to which component that is executing at time t, while more complex models define internal states for each component as well. The probabilistic aspects of Markov chains are defined through transition probabilities... 

The importance of software modeling within FTA is more obvious when we would like to present the difference of using different levels of diversity -e.g. different products of the same kind of technology (microprocessors) and different technologies (microprocessors and FPGA).

Spartan is a commercial software modelling kit having an easy-to-use graphical user interface (GUI) [31], It provides a range of Hartree-Fock and post-Haitree-Fock methods including density fimctional theoiy. The latest version is Spartanl4. It can be easily used for conformational analysis, spectral analysis, and reaction analysis. The suite is accompanied with properties and spectral databases. We will model the Diels-Alder reaction using Spartan 08 ... 

These examples can be difficult to see using only the text. Model kits or software models can help you visualize the three-dimensional nature of the shapes described here. 

The 3D melt-plotting is a computer-aided technique used for the fabrication of patient-specific implants or scaffolds endowed with a porous stracture which allows cell infiltration and vascularisation. The object to print can be designed by software or it is retrieved from a diagnostic examination such as X-ray or computer tomography. A computer-aided design software models and decomposes the object into two 2D slides. Thus, the digital information is sent to a robotic device (ie, Bioscaffolder) which builds up the object layer by layer (Seyednejad et al., 2011). PCL is one of the most used...
