This makes it possible to rewind the information to as it actually was in combination with as it was recorded at some point in time. In order to able do so, information cannot be discarded even if it is erroneous. Within, for example, financial reporting it is often desirable to be able to recreate an old report both as it actually looked at the time of creation and as it should have looked given corrections made to the data after its creation. Implementations of Bitemporal Modeling are mostly done using relational database s. As such, Bitemporal Modeling is considered different from Dimensional modeling Dimensional Modeling and complementary to database normalization . The upcoming SQL standard SQL 2011 will provide language constructs for working with bitemporal data. As no standard is yet in place, current solutions are vendor specific. Philosophy Bitemporal modeling uses bitemporal structures as the basic components. This results in the databases which have a consistent type of temporality for all data. Benefits of Bitemporal Modeling By focusing on completness and accuracy of data Bitemporal Modeling facilitates the creation of complete audit trails of data. Specifically this allows for queries which provide The most accurate data possible as we know it now Data as we knew it at any point in time When and why the most accurate data we had changed Data warehouse Category Data warehousing Category Data modeling Category Data modeling diagrams Category Database normalization database stub ... more details

Procedural modeling is an umbrella term for a number of techniques in computer graphics to create 3D models and texture mapping textures from sets of rules. L System s, fractal s, and Generative Modelling Language generative modeling are procedural modeling techniques since they apply algorithm s for producing scenes. The set of rules may either be embedded into the algorithm, configurable by parameters, or the set of rules is separate from the evaluation engine. The output is called procedural content, which can be used in computer games, films, be uploaded to the internet, or the user may edit the content manually. Procedural models often exhibit database amplification, meaning that large scenes can be generated from a much smaller amount of rules. If the employed algorithm produces the same output every time, the output need not be stored. Often, it suffices to start the algorithm with the same random seed to achieve this. Although all modeling techniques on a computer require algorithms to manage and store data at some point, procedural modeling focuses on creating a model from a rule set, rather than editing the model via user input. Procedural modeling is often applied when it would be too cumbersome to create a 3D model using generic 3D modeler s, or when more specialized tools are required. This is often the case for plants, architecture or landscapes. Procedural modeling ...

Unreferenced date December 2009 In computer science, Actor modeling is a form of software modeling , which focuses on software actors . Actor modeling is most prominently used for the early modeling of requirements through this it becomes possible to understand who the users and Project stakeholder stakeholders of a system are and what their interests and needs are regarding that system . The increasing complexity of today s systems makes it more appropriate to take this approach, instead of a traditional, more mechanically focused approach. When thinking along the dimensions of users and their needs, it is easier to comprehend what the system is designed to accomplish. This approach furthermore helps the users to define the requirements for the system. The approach of actor modeling is normally combined with the modeling of goals and tasks to give a better understanding of the situation the user is in. There are different modelinglanguage s that support actor modeling examples include i and EEML . The Actor The central entity of the Actor modeling the actor itself can be any kind of entity that is performing action s . It may for example be a person, a department, or an organization. The goal of actor modeling is to understand the actor better. To do so, it is important to understand the actor, who he is and why he does what he does. The actor has attributes that define it The actor has goals, skills and responsibilities. The actor performs tasks with a certain purpose in mind. The actor depends on other actors, resources or tasks. Relations The different actors in the model are in general not interdependent. It is therefore necessary to be able to put the actors in context. This can be done through different kinds of relations Connections between actors what is the relation between the actors Relations to tasks what does the user do Relations to goals what is the goal ...

multiple issues orphan February 2009 confusing June 2008 introrewrite June 2008 Participatory modeling is an approach which is a branch of the general field of conceptual modeling . Its specialisation is aimed towards involvement of a large number of people. Benefits obtained from this type of modeling is numerous, depending on the application area. In particular participatory modeling can give a high degree of ownership and motivation towards change for the people involved in the modeling process. There exists two major approaches which themselves provide highly different goals for the modeling Continuous modeling and conference modeling. Continuous modeling Continuous modeling focus on the end user being the active modeler. This can be incorporated into an adaptable, context sensitive, intelligent system, which is suited to the end user on an individual level, this combination is often termed model generated workplaces or model generated user environments. The idea is that the end user potentially has the greatest actual domain knowledge and thus the organization as a whole benefits by obtaining and externalization externalize this knowledge. Conference modeling Conference modeling is an approach where the goal often is of a more social kind, such as motivating, change management , externalization of knowledge and so on. The idea is to involve a large number of diversified people from the domain in question. Then the modeling process is performed in participation among them during a fixed period of time.

About the 3D modeling system the application of box modeling to complex systems Box model disambiguation Unreferenced date December 2009 Box modeling is a technique in 3D modeling where the model is created by modifying primitive shapes in a way to create a rough draft of the final model. This is in contrast with the edge modeling method, where the modeler edits individual vertex geometry vertices . While a primary function of box modeling involves extruding and scaling the flat planes that make up a model, called faces , another, more prominent feature of this art style gives it a second, less rudimentary name of subdivision surface subdivision modeling. Subdivision Subdivision surface Subdivision modeling is derived from the idea that as a work is progressed, should the artist want to make his work appear less sharp, or blocky , each face would be divided up into smaller, more detailed faces usually into sets of four . However, more experienced box modelers manage to create their model without subdividing the faces of the model. Basically, box modeling is broken down into the very basic concept of polygonal management. Quads Quadrilateral faces, commonly named quads , are the fundamental entity in box modeling. Obviously, if an artist were to start with a cube, the artist would have six quad faces to work with before extrusion. While most applications for three dimensional art provide abilities for faces up to any size, results are often more predictable and consistent when working with quads. This is so because of the fact if you were to draw an X connecting the corner vertices ... the model for software that can only handle triangles.

Expert subject date October 2010 unreferenced date October 2010 Simulation modeling is the process of creating and analyzing a Digital prototyping digital prototype of a physical model to predict its performance in the real world. Simulation modeling is used to help designers and engineers understand whether, under what conditions, and in which ways a part could fail and what loads it can withstand. Simulation modeling can also help predict fluid flow and heat transfer patterns. Uses of Simulation Modeling Simulation modeling allows designers and engineers to avoid repeated building of multiple physical prototypes to analyze designs for new or existing parts. Before creating the physical prototype, users can virtually investigate many digital prototypes. Using the technique, they can Optimize geometry for weight and strength Select materials that meet weight, strength, and budget requirements Simulate part failure and identify the loading conditions that cause them Assess extreme environmental conditions or loads not easily tested on physical prototypes, such as earthquake shock load Verify hand calculations Validate the likely safety and survival of a physical prototype before testing Typical Simulation Modeling Workflow Simulation modeling follows a process much like this Use a 2D or 3D CAD tool to develop a virtual model, also known as a digital prototype, to represent a design.

Loop modeling is a problem in protein structure prediction requiring the prediction of the chemical conformation conformations of loop biochemistry loop regions in protein s without the use of a structural template. The problem arises often in homology modeling , where the tertiary structure of an amino acid sequence is predicted based on a sequence alignment to a template , or a second sequence whose structure is known. Because loops have highly variable sequences even within a given structural motif or protein folding protein fold , they often correspond to unaligned regions in sequence alignments they also tend to be located at the solvent exposed surface of globular protein s and thus are more conformationally flexible. Consequently, they often cannot be modeled using standard homology modeling techniques. More constrained versions of loop modeling are also used in the data fitting stages of solving a protein structure by X ray crystallography , because loops can correspond to regions of low electron density and are therefore difficult to resolve. Regions of a structural model that were predicted by loop modeling tend to be much less accurate than regions that were predicted using template based techniques. The extent of the inaccuracy increases with the number of amino acid s in the loop. The loop amino acids side chain s dihedral angle s are often approximated from a rotamer library, but can worsen the inaccuracy of side chain packing in the overall model. Andrej Sali s homology modeling suite MODELLER includes a facility explicitly designed for loop modeling by a satisfaction of spatial restraints method. Short loops In general, the most accurate predictions are for loops of fewer than 8 amino acids. Extremely short loops of three residues can be determined from geometry alone, provided that the bond lengths and bond angles are specified. Slightly longer loops are often ... s loop modeling facility bioinformatics stub Category Bioinformatics Category Protein methods ... more details
Unified Science can refer to any of three related strands in contemporary thought. Belief in the unity of science was a central tenet of logical positivism . Different logical positivists construed this doctrine in several different ways, e.g. as a reductionism reductionist thesis, that the objects investigated by the special sciences reduce to the objects of a common, putatively more basic domain of science, usually thought to be physics as the thesis that all of the theories and results of the various sciences can or ought to be expressed in a common language or universal slang or as the thesis that all the special sciences share a common scientific method method . The writings of Edward Haskell and a few associates, seeking to rework science into a single discipline employing a common artificial language. This work culminated in the 1972 publication of Full Circle Haskell Full Circle The Moral Force of Unified Science . The vast part of the work of Haskell and his contemporaries remains unpublished, however. Timothy Wilken and Anthony Judge have recently revived and extended the insights of Haskell and his coworkers. Unified Science has been a consistent thread since the 1940s in Howard T. Odum s systems ecology and the associated Emergy Synthesis , modeling the ecosystem the geochemical, biochemical, and thermodynamic processes of the lithosphere and biosphere . Modeling such earthly processes in this manner requires a science uniting geology, physics, biology, and chemistry H.T.Odum 1995 . With this in mind, Odum developed a Energy Systems Language common language of science based on electronic schematics, with applications to ecology economic systems in mind H.T.Odum 1994 .
