Let us recall that, in Section 1, we introduced the utilization density f as the probability density of the geographical position of the animal during a time period. We also mentioned that the home range of an animal is frequently defined as the level set of the utilization density attaining...
For example, to make any practical use of the conventional density-functional theory, an explicit (perhaps approximate) expression for the energy functional (6.1) is necessary. An important contribution here was made by Kohn and Sham [9]. They proposed a certain decomposition of the energy ...
General mathematical form of crowd-density distributions Consider, as an example, a crowd at a political rally (Fig. 1a). Under such circumstances, individuals will seek the best locations—presumably closest to the stage—while avoiding overcrowded areas where there is insufficient “personal space....
–Sect. 3 gives three novel models for representing gray-scale images and RGB color images in open quantum systems and gives the process of quantum image preparation, –Sect. 4 introduces the environments and quantum noise channels and gives an example of a quantum image coupling with the enviro...
Taking Beijing (China) as an example, the concentric rings are shown in Fig. 2a. Fig. 2: Concentric ring analysis using 1-km series buffers in Beijing, China. a Urban land density. b Nighttime light intensity. The unit of nighttime light radiance is nW⋅cm−2⋅sr−1. Full size...
afor example the density of catheterization laboratories, specialists,hospital and ICU beds, and diagnostic imaging facilities (for example, an MRI down the hall from the physician’s office). 例如密度导尿实验室、专家、医院和例如ICU床和诊断想象 (设施, MRI击倒大厅从医师的办公室)。[translate]...
The following example uses the data set. The black curve is a gamma-kernel density estimate with a gamma start, the red curve a fully parametric gamma density and and the blue curve an ordinarydensityestimate. Notice the boundary bias of the ordinarydensityestimator. The underlying parameter esti...
a. Key Laboratory for Mountain Hazards and Earth Surface Process, Institute of Mountain Hazards and Environment (IMHE), Chinese Academy of Sciences (CAS), Chengdu 610041, China; b. University of Chinese Academy of Sciences (UCAS), Beijing 100049, China; c. Department of Civil Engineering, ...
The probability density function (PDF) is an expression used instatisticsthat defines the probability that some outcome will occur. In this function, the probability is the percentage of a dataset's distribution that falls between two criteria. PDF is commonly used byfinancial analyststo understand ...
