Weak Squares and Very Good Scales
نویسنده
چکیده
We assume the existence of a supercompact cardinal and produce a model with weak square but no very good scale at a particular cardinal. This follows work of Cummings, Foreman, and Magidor, but uses a different approach. We produce another model, starting from countably many supercompact cardinals, where κ,<κ holds but κ,λ fails for λ < κ.

Developing Rating Scale Descriptors for Assessing the Stages of Writing Process: The Constructs Underlying Students' Writing Performances
The purpose of the present study is to develop appropriate scoring scales for each of the defined stages of the writing process, and also to determine to what extent these scoring scales can reliably and validly assess the performances of EFL learners in an academic writing task. Two hundred and two students’ writing samples were collected after a step-by-step process oriented essay writing ins...
متن کاملA Comparative Study of Least-Squares and the Weak-Form Galerkin Finite Element Models for the Nonlinear Analysis of Timoshenko Beams
In this paper, a comparison of weak-form Galerkin and least-squares finite element models of Timoshenko beam theory with the von Kármán strains is presented. Computational characteristics of the two models and the influence of the polynomial orders used on the relative accuracies of the two models are discussed. The degree of approximation functions used varied from linear to the 5th order. In ...
متن کاملThe Failure of the Singular Cardinal Hypothesis and Scales
Starting from a supercompact cardinal κ, we build a model, in which κ is singular string limit, the singular cardinal hypothesis fails at κ and there are no very good scales at κ. Moreover there is a bad scale at κ, and so weak square fails.
متن کاملSpoofing Mitigation of GPS Receiver using Least Mean Squares-Based Adaptive Filter
The Global Positioning System (GPS) signals are very weak signal over wireless channels, so they are vulnerable to in-band interferences. Therefore, even a low-power interference can easily spoof GPS receivers. Among the variety of GPS signal interference, spoofing is considered as the most dangerous intentional interference. The spoofing effects can mitigate with an appropriate strategy in the...
