Formulario integrali proprietà e alcuni integrali particolari (mia)Domenico Tafuni
Integrali indefiniti, proprietà, integrazione per semplice trasformazione dell'integrando, integrazione per decomposizione in somma, integrazione delle funzioni razionali
This document discusses fuzzy sets and their basic concepts and operations. It begins by defining fuzzy sets and their membership functions, which assign a degree of membership between 0 and 1 to each element of a universal set, unlike crisp sets which only assign 0 or 1. It then discusses α-cut sets, which are crisp sets of elements with membership above a given value α. Other concepts covered include convex fuzzy sets, fuzzy numbers representing intervals, and the magnitude and subsets of fuzzy sets. Standard fuzzy set operations like complement, union, intersection and difference are also defined. Finally, fuzzy relations and their composition are introduced.

The document outlines an approach to summarize stability margins for multivariable feedback systems. It begins by introducing the problem of defining meaningful stability margins for multivariable systems. Next, it proposes using a PID controller of the form K(s) = K1 + K2/s + K3s with scalar values for each term. The problem is then defined as finding the ranges of these scalar values that ensure closed-loop stability. Finally, it proposes definitions for common and individual loop gain margins based on the stabilizing ranges of the scalar values. The approach aims to generalize stability margin concepts from single-input single-output systems to multivariable systems.
Tutorial of topological_data_analysis_part_1(basic)Ha Phuong
This document provides an overview of topological data analysis (TDA) concepts, including:
- Simplicial complexes which represent topological spaces and holes of different dimensions
- Persistent homology which tracks the appearance and disappearance of holes over different scales
- Applications of TDA concepts like using persistent homology to analyze protein compressibility.
This is a discussion of the presentations of John Geweke and of Sylvia Früwirth-Schnatter, during the ICMS convference on March 3-5, 2010, in Edinburgh
Graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. A graph consists of vertices and edges connecting pairs of vertices. There are many types of graphs including trees, which are connected acyclic graphs. Spanning trees are subgraphs of a graph that connect all vertices using the minimum number of edges. Key concepts in graph theory include paths, connectedness, cycles, and isomorphism between graphs.
Cordal graphs are graphs where every cycle of 4 or more vertices has an edge connecting two non-adjacent vertices (a chord). There are three equivalent properties of cordal graphs: 1) they are chordal, 2) they have a perfect elimination ordering, and 3) minimal vertex separators induce complete subgraphs. The LEX BFS algorithm uses a lexicographic breadth-first search to find a perfect elimination ordering in polynomial time, identifying if a graph is cordal. It partitions the vertices into adjacent and non-adjacent sets at each step until all vertices are visited.

Floyd Warshall algorithm easy way to compute - MalingaMalinga Perera
The document demonstrates the Floyd-Warshall algorithm for finding the shortest paths between all pairs of vertices in a weighted graph. It shows the algorithm being applied to a sample graph with 4 vertices through a series of steps where the distances are updated. In each step, it considers all vertices as possible intermediates and updates the distances between vertex pairs accordingly until it reaches the shortest paths between all pairs of vertices in the graph.
آموزش روش های حل روابط بازگشتی - بخش چهارمfaradars
در ریاضیات، رابطه بازگشتی (Recurrence Relation)، دنباله ای است که به صورت بازگشتی تعریف می شود. در یک دنباله بازگشتی، یک معادله به نام رابطه بازگشتی ارائه می شود که با آن، جمله n ام دنباله به جملات پیشین مرتبط می شود. مقادیر چند جمله اول دنباله به نام های شرایط مرزی یا مقادیر اولیه، داده می شوند.
سرفصل هایی که در این آموزش به آن پرداخته شده است:
درس یکم: روابط بازگشتی
درس دوم: روش درخت بازگشت (recursion tree)
درس سوم: قضیه اصلی -تغییر متغیر
درس چهارم: رابطه های بازگشتی همگن

Algorithm Design and Complexity - Course 8Traian Rebedea
The document discusses algorithms for finding strongly connected components (SCCs) in directed graphs. It describes Kosaraju's algorithm, which uses two depth-first searches (DFS) to find the SCCs. The first DFS computes a finishing time ordering, while the second DFS uses the transpose graph and the finishing time ordering to find the SCCs, outputting each SCC as a separate DFS tree. The algorithm runs in O(V+E) time and uses the property that the first DFS provides a topological sorting of the SCCs graph.
