Sistesis aliran ekuivalen tree dengan menggunakan algoritma gomary - hu

ABSTRAK Suatu jaringan komunikasi tak berarah G(V, E, c, f) merupakan suatu jaringan komunikasi dengan himpunan titik V, himpunan garis E, fungsi kapasitas c dan fungsi aliran f. Dalam jaringan komunikasi ini, medium antar dua station yang dalam hal ini digambarkan sebagai garis mempunyai kapasitas yang disebut sebagai kapasitas garis. Dad kapasitas garis ini dapat ditentukan kapasitas terminalnya. Setiap jaringan komunikasi tak berarah -n-titik adalah ekuivalen terhadap tree dan terdapat paling banyak n - 1 bilangan kapasitas terminal yang berbeda. Algoritma Gomory - Hu membangun jaringan yang ekuivalen terhadap tree dengan menyelesaikan secara tepat masalah aliran maksimum n - 9. Masalah aliran maksimum ini diselesaikan daiam suatu jaringan yang lebih sederhana daripada jaringan asli

Optimal Alphabetic Ternary Trees

We give a new algorithm to construct optimal alphabetic ternary trees, where every internal node has at most three children. This algorithm generalizes the classic Hu-Tucker algorithm, though the overall computational complexity has yet to be determined

Comment on "Effects of Point Defects on the Phase Diagram of Vortex States in High-Tc Superconductors in the B || c Axis"

We comment on a recent work by Nonomura and Hu who simulated the 3D XY model for a type-II superconductor in an applied magnetic field, in the presence of uncorrelated point randomness. We clarify the nature of the "vortex slush" state that they found, and argue that this state is unstable in the thermodynamic limit.Comment: 2 pages, 2 figure

The Making of a Movement: The Archival Reconstruction of Chicanismo in Northern New Mexico

The recovery of a movement is explored in this project inspired by the New Mexico Highlands University (HU) Archives and Special Collections. Known for its liberal student body in the 1960s and 1970s, I argue that HU was a catalyst for the Chicano Movement in northern New Mexico. The movement was punctuated by an influx of visitations by prominent activists such as Reies Lopez Tijerina and Rudolfo “Corky” Gonzales. Campus life at HU shifted from an Anglo-centric atmosphere to fostering a cultural space fueled by the Spanish language and the overt accusations of racism against minority students. Through my work, I show how Anglo and Chicano students confided in their school newspaper to express personal opinions and engage in racially charged correspondences across both groups. These conversations ignited a Chicano-student-based effort to elect the first Nuevomexicano and Chicano president of HU. These protests necessitated the involvement of the HU Board of Regents, whose readiness to elect a university president under such stipulations oscillated over the course of a year. Their responses to Chicano students are recorded in the HU Archives. I assert that the contrast of dialogues produced from the administrative entity and Chicano students reveals the latent racial tensions present on the HU campus. Finally, I demonstrate the manifestation of Mexican-American identity by investigating its historical contexts in New Mexico and its implications through a national lens. Post-Vietnam War sentiments speckle the racial commentary of students’ published works through art, poetry, and articles published in Spanish. By investigating primary, non-fictional sources, I work to reconstruct an historical movement and weave social commentary within a politically infused undertaking of exploring identity

Geometry of weak lensing of CMB polarization

Hu [Phys. Rev. D62 (2000) 043007] has presented a harmonic-space method for calculating the effects of weak gravitational lensing on the cosmic microwave background (CMB) over the full sky. Computing the lensed power spectra to first order in the deflection power requires one to formulate the lensing displacement beyond the tangent-space approximation. We point out that for CMB polarization this displacement must undergo geometric corrections on the spherical sky to maintain statistical isotropy of the lensed fields. Although not discussed by Hu, these geometric effects are implicit in his analysis. However, there they are hidden by an overly-compact notation that is both unconventional and rather confusing. Here we aim to ameliorate this deficiency by providing a rigorous derivation of the lensed spherical power spectra.Comment: 3 page

Dynamic Steerable Blocks in Deep Residual Networks

Filters in convolutional networks are typically parameterized in a pixel basis, that does not take prior knowledge about the visual world into account. We investigate the generalized notion of frames designed with image properties in mind, as alternatives to this parametrization. We show that frame-based ResNets and Densenets can improve performance on Cifar-10+ consistently, while having additional pleasant properties like steerability. By exploiting these transformation properties explicitly, we arrive at dynamic steerable blocks. They are an extension of residual blocks, that are able to seamlessly transform filters under pre-defined transformations, conditioned on the input at training and inference time. Dynamic steerable blocks learn the degree of invariance from data and locally adapt filters, allowing them to apply a different geometrical variant of the same filter to each location of the feature map. When evaluated on the Berkeley Segmentation contour detection dataset, our approach outperforms all competing approaches that do not utilize pre-training. Our results highlight the benefits of image-based regularization to deep networks
