For this purpose, a compression field model originally developed for steel reinforced concrete beams is adopted. The proposed resistance model is validated by means of a databank evaluation. Moreover, an equatio
Engineering insight combined with parametric studies is still ubiquitous in parameter tuning of antenna structures35,36. Nevertheless, rigorous numerical algorithms are the only way to yield optimum designs. Despite the abundance of available methods, EM-based optimization is still challenging due to bein...
Consequently, it is possible to conduct relevant analy sis on the total mass of variable loads and permanent loads, and the overall mass of structure. Among them: In this paper, the mass ratio of permanent loads to variable loads is defined as: Where Rm denotes permanent loads to ...
Table 1 presents some examples of typical design scenarios which involve antenna reflection response, size, as well as some of field characteristics such as axial ratio or gain. Therein, f denotes the frequency, |S11(x,f)| represents the modulus of the reflection coefficient at vector x and ...
The difference between two solutions S and S′′ can be measured through a distance function ρ(S,S′′) with codomain [0,1], which computes the ratio between the number of jobs that are not assigned to the same period in both solutions and the total number of jobs. Let Spi and Spi...
during the tracking stage, the drift subcategories are identified based on the different tracking flow ratio curves generated during the window tracking process. Therefore, this method is able to effectively identify the type of CD, accurately analyze the key information in the online learning process...
Planning for the Unexpected: A contingency refers to a future event or situation that may occur but cannot be accurately predicted to say whether it definitely will or won't happen. Think of this like creating a plan for a possible what-if situation. ...
What is the operation and effect of positive reinforcement? What is the purpose of effect size? What is science? Explain. Describe how risk affects decision making. What is the empirical law of effect? What is the significance of the placebo effect? What is a positive reinforcer? What was ...
The problem (1) can be generalized to handle other types of goals, for example, impedance matching improvement over fractional bandwidths centred atft.j, maximization of the impedance bandwidth, minimization of axial ratio, improvement of the antenna gain, etc. As mentioned earlier, the specific ...
structures in nature and civil constructions: (a) Gradation model of soil porous material, exhibiting a gradual variation in soil particle density and porosity from the top to the ground; (b) Artificial aluminum foam, a typical functionally graded material with a high strength-to-density ratio. ...
