An unsatisfactory property of particle filters is that they
may become inefficient when the observation noise is low.
In this paper we consider a simple-to-implement particle filter,
called ‘LIS-based particle filter’, whose aim is to overcome
the above mentioned weakness. LIS-based particle
filters sample the particles in a two-stage process that uses
information of the most recent observation, too. Experiments
with the standard bearings-only tracking Problem indicate
that the proposed new particle filter method is indeed
a viable alternative to other methods.
We have a group of N items (represented by integers from 1 to N), and we know that there is some total order defined for these items. You may assume that no two elements will be equal (for all a, b: a<b or b<a). However, it is expensive to compare two items. Your task is to make a number of comparisons, and then output the sorted order. The cost of determining if a < b is given by the bth integer of element a of costs (space delimited), which is the same as the ath integer of element b. Naturally, you will be judged on the total cost of the comparisons you make before outputting the sorted order. If your order is incorrect, you will receive a 0. Otherwise, your score will be opt/cost, where opt is the best cost anyone has achieved and cost is the total cost of the comparisons you make (so your score for a test case will be between 0 and 1). Your score for the Problem will simply be the sum of your scores for the individual test cases.
這是一個模擬第3類模式地震波的matlab腳本。
This a collection of Matlab scripts that solve the antiplane
(mode III) earthquake dynamic Problem with slip-weakening friction,
on a 1D fault embedded in a 2D homogeneous elastic unbounded medium.
The Problem is formulated as a boundary integral equation
and the elastodynamic kernels are analytically derived in
the spectral domain (spatial wavenumber).
The method is explained e.g. by Morrysey and Geubelle (1997),
and has been improved and extensively used by Nadia Lapusta,
Alain Cochard, etc.
Software developers need to have a number of traits in order to practice their
craft well. First, they must be good analytical thinkers and Problem solvers. A
developer’s primary role is to create software that solves business Problems.
This requires analyzing customer needs and coming up with successful, creative
solutions.
As all of you know, MATLAB is a powerful engineering language. Because of some limitation, some tasks take very long time to proceed. Also MATLAB is an interpreter not a compiler. For this reason, executing a MATLAB program (m file) is time consuming. For solving this Problem, Mathworks provides us C Math Library or in common language, MATLAB API. A developer can employ these APIs to solve engineering Problems very fast and easy. This article is about how can use these APIs.
