Making a statement about change or directionality, such as describing the quantity of food or water decreasing, is a relatively simple task in systems thinking, but is foundational to more complex tasks that consider changes over time (Sweeney and Sterman, 2007). Students who described trade-...

Such an approach is ideal to describe the combined effects of high contaminant exposure and food stress for a species like the polar bear (Ursus maritimus) facing reduced food availability and quality due to sea-ice changes in a warming climate. Although DEBkiss has been shown to work well ...
Difficulty in practical implementation Voltage varies during load changes Simple and ameliorate the frequency loop The dynamic response is not fast The dynamic response is improved, suitable for small DGs and PQ sharing is also desired. Not suitable for the heavy load. Small droop gain create ...
changes at the same measuring point of each precast beam monitored on the first floor of the building, as shown in Figure 18, the analysis shows that: (1) The stress values of the measured points at each beam end are relatively discrete and the stress curves deviate significantly, which is...
In fact, due to the changes of the objective environment, the one-step status for the transition probability matrix of an adjacent time is not the same, so there is a certain error between αpt ` 1q and αptq P. Based on the principle of the minimum sum of squared errors, the ...
In addition, if electricity supply is required only when the transmittance changes, it would not be necessary to supply electricity below the desired transmittance [4]. On the other hand, the disadvantage of EC glazing is that, when the transmittance changes, EC glazing has a slow response ...
The building geometric model represents the target building in the design stages and comprises all components, including design parameters, changes, modifications, and manipulations implemented by the model optimizer/operators, such as an architect, designer, and engineer. To optimize the building ...
Introduction Energy efficiency is a key factor for environmental, social and economic development [1], being the main driver for the mitigation of climate changes [2]. A significant reduction in energy consumption, in fact, seems to be the most viable option to fight the current worldwide ...
Daily and weekly changes in demand are mainly correlated to energy usage patterns of consumers. Normal distribution is a very popular load distribution and is widely used [33]. The probability density function (PDF) for the normal distribution of load is given by the following equation: f (PL...
