Model glue should dry fast and have little odor, and work on different substrates. Liquid glue applied with a brush is best, as it can be painted over and provides a quick set. Early glues were toxic, but modern ones are more reliable. There are two types of glue: tube and brush. Brush glue is […]
Model rockets are small vehicles made of lightweight materials that hobbyists can build and launch at lower altitudes. They use disposable motors and parachutes to recover the craft. A launch pad and special packaging are required, and an electric match ignites the rocket engine. Recovery can be problematic due to parachute snags. A model rocket […]
Model trains come in different sizes, or scales, with the most common being HO and N. HO is the easiest to find and accessorize, while N uses less space. Other scales include O, G, and Z, with G being used for garden railways and Z being very small and difficult to work with for some. […]
Model yachts offer a budget-friendly way to experience boating. They come in various designs and can be radio-controlled or wind-powered. Some models require assembly, and attention to detail is a key feature. Yachts can be powered by different systems, including electric and hydro power. Tug models are also available for simulated salvage operations. For those […]
Rapid prototype models are created from computer drawings and allow customers to review products under development. 3D software and printers have revolutionized the process, allowing for virtual testing and the creation of physical samples using plastic, metal, or powder. Some products are designed entirely in CAD software, eliminating the need for physical prototypes. Test software […]
The Goodwin model predicts economic cycles based on employment rates and productivity levels, derived from Marxist theories of class struggle and predator-prey behavior. It assumes opposing elements of a system are inherently antagonistic, but fails to predict economic trends in complex systems like the 2008 global economic crisis. The Goodwin model is a macroeconomic theory […]
A decision model is a visual aid used to help individuals or groups make decisions about a problem or situation. There are many different models, and the choice depends on those involved and the problem. After formulating the model and analyzing information, a decision is made and an action plan is implemented. Decision models can […]
Econometrics uses statistical analysis to predict economic trends through econometric models, which establish and test relationships between economic factors. Developed by Norwegian economist Ragnar Frisch in the 1930s, econometric modeling is an uncertain science that incorporates probability due to human behavior. Governments and central banks use econometric data to guide fiscal management strategies, but critics […]
A business reference model (BRM) describes the structure and operations of an organization in a hierarchical manner, allowing for a deeper understanding of how it works. It includes three main components: business areas, lines of business, and business resources. Other templates, such as technical, service, or performance reference models, link to the BRM. Based on […]
Attrition models analyze organizational friction, such as employee turnover or student dropouts, using mathematical modeling. Statisticians use data on attrition rates to identify patterns, assess program success, and forecast future changes. Some models contain confidential information and may be used for internal purposes only. A attrition model is a mathematical analysis of organizational friction, such […]
Business intelligence uses computer-based processes to capture and analyze data for operational improvements and selecting new business opportunities. It includes economic and accounting factors, and can help measure performance and trends. Business intelligence refers to a computer-based set of processes that business owners and managers use to capture and analyze data related to their companies. […]
Pattern welding is a metalworking technique used in sword and knife making, originating in Damascus during the 11th century. It combines layers of metal to create unique appearances and enhanced physical properties. Modern metalworkers use high carbon and tool steel to produce intricate designs, but too many layers can result in a weaker sword. The […]
ASP business model provides software applications and servers to customers over the internet, with top-notch security measures and timely billing. It is tailored to the needs of the ASP and its customer base, and can be employed by any company. The typical Application Service Provider (ASP) business model involves owning, operating and securing software applications […]
Choosing a software business model requires understanding the methods used to sell software, such as standalone or subscription models. Traditional models involve selling licenses per CPU, while web-based apps are sold on a subscription basis. Consulting businesses must quote queries on an hourly basis. Marketing is crucial due to low development costs. Choosing a software […]
The Theory of Reasoned Action predicts that personal attitudes and social norms guide behavioral intention. The Technology Acceptance Model (TAM) is a specific application of Reasonable Action to software adoption, with key terms including Perceived Ease of Use, Perceived Usefulness, Behavioral Intent to Use, and Actual behavior. TAM has been studied in various software and […]
Input-output models describe economic relationships and can be used for forecasting and analyzing effects of changes. Wassily Leontief developed the model and received a Nobel Prize. The models can analyze individual companies and related concepts include economic base analysis and shift-shift analysis. An input-output model is a way of describing the economic relationships between suppliers […]
Mental models shape thought processes, behaviors, and responses to situations. Kenneth Craik proposed the mental model theory in the 1940s, and it has been built upon to explore mental model formation. Intellectual disability and mental illness can inhibit mental model development. Mental models help people understand and apply patterns in human behavior. Culture and environment […]
The Common Information Model (CIM) is a way to manage and visualize resources in an IT environment. It was created by the Distributed Management Task Force (DMTF) and follows the Object Oriented Model (OOM) methodology. CIM separates a specification and a schema to identify objects in an environment and uses the Unified Modeling Language (UML) […]
The singleton pattern is a programming concept that allows programs to access a specific set of information only once and always contain the same set of instructions or information. It is used to define a global variable, which stays the same and only needs to be defined once. This saves space in computer memory and […]
A factory is an object used to create other objects in computer programming. It relies on methods to generate specific objects and uses a common interface to interact with programs. The factory model allows for flexibility and easy changes to the program. In computer programming, a factory is an object used to create other objects. […]
