Finitely Repeated Games

2025
Repeated games are scenarios where the same game is played multiple times by the same participants. These games are fundamental in understanding how decision-making processes evolve over time. Finitely Repeated Games: These games occur a specific number of times. Consider two software firms that are in competition, releasing updates to their software every quarter. Each quarter, these firms must decide on their strategic approach: they can either invest heavily in developing innovative new...

This protocol describes the study of the quasi-static compression performance of corrugated tapered tubes using finite element simulations. The influence of the thickness gradient on the compression performance was investigated. The results show that proper thickness gradient design can change the deformation mode and significantly improve the energy absorption performance of the tubes.

Melting Land and Sea Ice ExpandNOTE: This activity is a simulation of land- and sea-ice melting and their effects on water levels. First, label one graduated cylinder as 'Sea Ice' and the other graduated cylinder as 'Land Ice.' Hypotheses: the experimental hypothesis might be that the land ice melting will cause the water level to rise more than the melting sea ice. The null hypothesis would be that there will be no difference in the change in water level between the two containers. Add 10 ice...

Climate Change - Concepts

2019
The certainty of climate change remains a public controversy despite the consensus among approximately 97% of active climate researchers, who not only agree that the Earth’s climate is changing but also state that this change is intensified by human activity, predominantly carbon emissions 1. The disconnect between the public and the experts is partly due to poor understanding of the mechanisms involved in climate change as well as the differences among essential concepts such as weather and...

Subtraction order determines the sign of the result. Using the final value minus the initial value produces a positive result when the quantity increases and a negative result when it decreases. This sign preserves the direction of the change in the calculation, helping distinguish an increase from a reduction in position, velocity, energy, temperature, or another measured quantity.
A finite change describes what happens across an interval between two distinct states, so it supports an average description over that interval. An instantaneous change instead concerns behavior at a particular point and is represented through derivatives or differential quantities. Comparing these ideas prevents an average result from being interpreted as the exact behavior at every moment.
The initial and final states establish the two reference conditions required for comparison. Their values determine both the magnitude and sign of the result, while the physical quantity being compared determines what the change represents. Selecting clearly defined endpoints allows measured conditions to be connected to an observable outcome rather than treated as an isolated value.
First identify the physical quantity and record its initial and final values using consistent units. Then subtract the initial value from the final value according to ΔQ = Q_final − Q_initial. Finally, interpret the sign and magnitude in context. This procedure can be applied to position, velocity, time, energy, or temperature when two states are available.
A change in position evaluated over a corresponding time interval provides the basis for average velocity. The position difference identifies how far the system moved between the selected states, while the time difference identifies the interval over which that movement occurred. This result describes average behavior across the interval, not necessarily the velocity at any single instant.
Finite changes connect initial and final conditions in several physical calculations. Changes in energy can describe energy conversion between states, while work and heat transfer can be related to changes observed over an interval. Comparing the starting and ending values helps identify the net outcome of a process and links mathematical calculations with measurable physical behavior.
