Scale-up (chemical Engineering)
Scale up, scale-up, or scaleup may refer to: *Scalability, the ability to function with different amounts of required work, or to be readily adjusted to do so *Scaleup company See also * Image scaling, also known as "upscaling" an image * SCALE-UP, a type classroom layout and learning environment * Video scaler A video scaler is a system which converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as 1080i hig ...

Scalability
Scalability is the property of a system to handle a growing amount of work by adding resources to the system. In an economic context, a scalable business model implies that a company can increase sales given increased resources. For example, a package delivery system is scalable because more packages can be delivered by adding more delivery vehicles. However, if all packages had to first pass through a single warehouse for sorting, the system would not be as scalable, because one warehouse can handle only a limited number of packages. In computing, scalability is a characteristic of computers, networks, algorithms, networking protocols, programs and applications. An example is a search engine, which must support increasing numbers of users, and the number of topics it indexes. Webscale is a computer architectural approach that brings the capabilities of large-scale cloud computing companies into enterprise data centers. In mathematics, scalability mostly refers to closure u ...

Scaleup Company
A scaleup company or just scaleup is defined by the OECD as a company having an average annualized return of at least 20% in the past 3 years, and had at least 10 employees at the start of the 3 year period. A scaleup can be identified as being in the "growth phase" life-cycle in the Millers and Friesen life cycle theorem, or the "Direction phase" in the Greiner growth curve. The importance of scaleups and the rise of their terminology according to the World Economic Forum is that, although not all startups make it big, the ones that do greatly impact society by means of new technology, services and increased employment. To aid this rise, instead of large startup incubators, policy makers are more and more focusing on scaleups since they are the ones that add value. One commonly used definition of 'scaleup' is the OECD-Eurostat definition relating to 'gazelles' or High Growth Firms: "All enterprises with average annualised growth greater than 20% per annum, over a three year ...

Image Scaling
In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement. When scaling a vector graphic image, the graphic primitives that make up the image can be scaled using geometric transformations, with no loss of image quality. When scaling a raster graphics image, a new image with a higher or lower number of pixels must be generated. In the case of decreasing the pixel number (scaling down) this usually results in a visible quality loss. From the standpoint of digital signal processing, the scaling of raster graphics is a two-dimensional example of sample-rate conversion, the conversion of a discrete signal from a sampling rate (in this case the local sampling rate) to another. Mathematical Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem. According to ...

SCALE-UP
SCALE-UP, Student-Centered Active Learning Environment with Upside-Down Pedagogies, is a classroom specifically created to facilitate active, collaborative learning in a classroom. The spaces are carefully designed to facilitate interactions between teams of students who work on short, interesting tasks revolving around specific content. Some people think the rooms look more like restaurants than classrooms. History Originally developed in 1997 by Robert Beichner at North Carolina State University to help with large enrollment physic courses. At this time, SCALE-UP stood for 'Student-Centered Activities for Large Enrollment Undergraduate Physics.' Although originated at North Carolina State University, more than five hundred colleges across the US and around the world are known to have directly adopted the SCALE-UP model and adapted it to their particular needs. When SCALE-UP was incorporated in different disciplines then the name was changed to 'Student-Centered Active Learning ...
