A simulation is the imitation of the operation of a real-world process or system over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games.

To ensure numerical stability, the time steps in an MD simulation must be short, typically only a few femtoseconds (10–15 s) each. Most of the events of biochemical interest—for example, functionally important structural changes in proteins—take place on timescales of nanoseconds, microseconds, or longer.

Time-scale: Optical phonon frequencies are ~10 THz – period of ~100 fs. Therefore, a typical timestep in MD simulation is on the order of a femtosecond. Using modern computers it is possible to calculate 106 – 108 timesteps. Therefore we can only simulate processes that occur within 1 – 100 ns.

Constant temperature, constant volume (NVT) (default). Constant temperature, constant pressure (NPT).

(The NVT ensemble is also known as the isothermal-isochoric ensemble, while the NPT ensemble is also known as the isothermal-isobaric ensemble). For equilibration, the protein must be held in place while the solvent is allowed to move freely around it.

Communication with the TCP/IP device over the Ethernet network can be extended to more functions using NVT (Network Virtual Terminal) commands. It can be used according to the RFC2217 standard to change baudrate on remote Virtual Serial Port for example.

The isothermal–isobaric ensemble (constant temperature and constant pressure ensemble) is a statistical mechanical ensemble that maintains constant temperature and constant pressure applied. It is also called the -ensemble, where the number of particles.

The Gibbs ensemble Monte Carlo method has been specifically designed to characterize phase transitions. It was mainly developed by Panagiotopoulos to avoid the problem of finite size interfacial effects. In this method, an NVT (or NpT) ensemble containing two (or more) species is divided into two (or more) boxes.

In statistical mechanics, a grand canonical ensemble (also known as the macrocanonical ensemble) is the statistical ensemble that is used to represent the possible states of a mechanical system of particles that are in thermodynamic equilibrium (thermal and chemical) with a reservoir.

The partition function is a measure of the volume occupied by the system in phase space. Basically, it tells you how many microstates are accessible to your system in a given ensemble.

In physics, specifically statistical mechanics, an ensemble (also statistical ensemble) is an idealization consisting of a large number of virtual copies (sometimes infinitely many) of a system, considered all at once, each of which represents a possible state that the real system might be in.

Ensemble Methods in Machine Learning | 4 Types of Ensemble Methods.

Ensembles are predictive models that combine predictions from two or more other models. A minimum benefit of using ensembles is to reduce the spread in the average skill of a predictive model. A key benefit of using ensembles is to improve the average prediction performance over any contributing member in the ensemble.

Ensemble members help bring the world of musicals and operas to life by performing intricate dance parts, adding their voices to full-company musical numbers, and acting out background parts.

A strong ensemble is the same as a strong cast – actors who play well-defined characters. Every actor in the ensemble should have an individual character. Sometimes it’s hard for your ensemble actors to believe they’re as important as the leads. It’s up to you to create a full theatrical experience for your ensemble.

Tips for Ensemble Playing

1. Listen with your ears and eyes. Pay attention to tone, gesture, movement and sound.
2. Develop 360 degree awareness of your play mates.
3. Play together.
4. It’s NOT about you.
5. Surprise yourself.
6. Give into what’s happening.
7. Get out of your head and into your body.
8. Work outside your comfort zone.

As nouns the difference between company and ensemble is that company is a team; a group of people who work together professionally while ensemble is a group of separate things that contribute to a coordinated whole.

A swing refers to a member of the company who understudies several ensemble roles. These ensemble roles are called “tracks.” The only time a swing performs is if an ensemble member is out of the show or if an ensemble member is covering another role in the show, as many ensemble members also have understudy duties.

As a professional description most performers in musical plays would probably describe themselves as actors.
