Gerrymandering and Compactness: Implementation Flexibility and Abuse [PDF]
Political Analysis, 2018 Political districts may be drawn to favor one group or political party over another, or gerrymandered. A number of measurements have been suggested as ways to detect and prevent such behavior.

Freeform spectrometer enabling increased compactness
Light: Science & Applications, 2017 We present optical designs with freeform optics in the context of hyperspectral imaging. Results show designs that are 5 × more compact in volume than similar designs using conventional spherical or aspherical surfaces.

Weak Compactness Techniques and Coagulation Equations [PDF]
, 2018 Smoluchowski’s coagulation equation is a mean-field model describing the growth of clusters by successive mergers. Since its derivation in 1916 it has been studied by several authors, using deterministic and stochastic approaches, with a blossoming of ...

Nanomaterials, 2019 Although a compact holes-transport-layer (HTL) film has always been deemed mandatory for perovskite solar cells (PSCs), the impact their compactness on the device performance has rarely been studied in detail. In this work, based on a device structure of

On effective compactness and sigma-compactness
, 2011 Using the Gandy -- Harrington topology and other methods of effective descriptive set theory, we prove several theorems on compact and sigma-compact pointsets. In particular we show that any $\Sigma^1_1$ set $A$ of the Baire space $N^N$ either is covered

A New Cluster Validity Index Based on Local Density of Data Points
AxiomsMultiple cluster validity indices (CVIs) have been introduced for diverse applications. In practice, clusters exhibit varying shapes, sizes, densities, and closely spaced centers, which are typically unknown beforehand.

Compactness and collective compactness in spaces of compact operators
Journal of Mathematical Analysis and Applications, 1981 AbstractThis is a study of compactness in (a) spaces Kb(X, Y) of compact linear operators, (b) injective tensor products X \̃boϵ Y, and (c) spaces Lc(X, Y) of continuous linear operators, and its various relationships with equicontinuity and collective compactness.

Ideal-quasi-Cauchy sequences [PDF]
, 2012 An ideal $I$ is a family of subsets of positive integers $\textbf{N}$ which is closed under taking finite unions and subsets of its elements.

IEEE Access, 2022 Modular multilevel converters (MMCs) are widely utilized in dc applications. With the development of MMCs, many applications require the MMCs to have additional functions and characteristics, such as dc fault clearing capability and low submodule ...
