The topic of “strain” (ε) always comes up when considering the strength and structure of a product. 1 For example, if a metallic bar is pulled from both ends, the length will be extended slightly from the original length. 2 Likewise, if a metallic bar is pushed from both ends, the...
Circular structure Circular organizational structures are centralized structures with a hierarchical reporting system. Lower-level employees report to managers, who report to directors, all the way up to senior leadership. This chain of command resembles hierarchical structures, but it is represented differ...
μ is the scale parameter of the nest normalized from the top; it should be greater than or equal to 1. The inverse of the scale parameter ranges from 0 to 1 in this case (Bierlaire, 1998). If μ is estimated to be 1, the choice model follows an MNL structure. n represents the ...

Results: The known structures are compared to the proteins encoded by eight complete microbial genomes in terms of simple statistics such as sequence length, composition and secondary structure. The known structures are represented by a collection of nonhomologous domains from the PDB and a smaller ...
The impurity of a node is represented by a Gini index. The determination of the Gini Index can be defined as subtracting the sum of squared probabilities of each class from one. If the samples of class Z are contained in a subset of A then the impurity Gini(A) can be defined as seen...
The trade-off is that we are imposing our own structure and theoretical hypotheses onto the model. If these theoretical hypotheses as to how a task is divided among components are sub-optimal, then the resulting model will also be sub-optimal. Indeed, it is for this reason that we can ...
As the preceding code shows, each column in a table is represented by a TableColumn object. TableColumn supplies getter and setter methods for the minimum, preferred, and maximum widths of a column, as well as a method for getting the current width. For an example of setting cell widths ...
This chapter is a basic tour of the kernel-provided device infrastructure in a functioning Linux system. 本章是对Linux系统中内核提供的设备基础架构的基本介绍。 Throughout the history of Linux, there have been many changes to how the kernel presents devices to the user. We’ll begin by looking...
