Eksistensi Kesetimbangan Nash Pada Quantum Prisoner’s Dilemma Untuk Dua Pemain Kuantum
Get PDFTelah dikaji eksistensi kesetimbangan Nash pada quantum prisoner’s dilemma dengan efek dekoherensi. Kesetimbangan Nash diperoleh pada interval dekoherensi 0,622 <p <=1 dan hilang pada interval dekoherensi 0,622 <p <=1. Interval dekoherensi pada quantum prisoner’s dilemma diperoleh dengan mengevaluasi kesetimbangan Nash pada strategi kuantum Q untuk dua pemain. Hasil tersebut sesuai dengan kasus multiplayer quantum prisoner’s dilemma [15]
Pengujian Optimalisasi Jaringan Kabel Fiber Optic Di Universitas Islam Indonesia Menggunakan Minimum Spanning Tree
Get PDFUniversitas Islam Indonesia (UII) intergrated campus computer network built since 1995. Development of UII integrated campus computer network is using a star topology and fiber optic (FO) cable. Considering that the star topology is the topology that requires a lot of wires, this study was conducted to determine and examine how the application of graph on the FO cable network UII integrated campus in order to minimize the cost, because FO cable network can be modeled by a graph where the buildings as points, while FO cable that connects to each building as a line. This type of research that is used here is a case study, in which data collection by observation, interviews, and documentation. This study used 4 algorithms, that is Kruskal algorithm, Prim, Boruvka and Solin algorithm to find the Minimum Spanning Tree. Based on the research that has been done, the conclution about the troubleshooting steps of optimization UII integrated campus FO cable network based graph theory has been got. From the four algorithms obtained the most optimal results FO cable length 4.700 meters long and is 1.590 meters cable lines. While the results of observations made, it is known that the existing computer network in UII integrated campus has a cable length of 6.120 meters and 2.050 meters long track. The results of the analysis showed that the resulrs of the study 23.2% more optimal than the existing computer networks in UII integrated campus
Penyelesaian Masalah Nilai Batas Persamaan Diferensial Mathieu–Hill
Get PDFBerbagai masalah fisis dan geometri yang melibatkan dua fungsi atau lebih peubah bebas sangat berkaitan dengan persamaan diferensial. Salah satu analisis fisis tersebut dapat dinyatakan dalam bentuk persamaan diferensial. Ilmuwan matematika yang bernama George W. Hill dan Mathieu meneliti tentang getaran pada pendulum gantung yang bisa dimodelkan dalam bentuk persamaan diferensial Mathieu-Hill. Persamaan diferensial Mathieu-Hill adalah persamaan diferensial orde dua yang didalam fungsi tersebut terdapat fungsi periodik. Persamaan diferensial Mathieu-Hill dapat diselesaikan dengan menggunakan metode aljabar matriks. Pada tahun 2005 sudah diteliti tentang solusi dari persamaan diferensial Mathieu-Hill. Penelitian ini menjelaskan tentang penyelesaian masalah nilai batas pada persamaan diferensial Mathieu Hill yang akan manghasilkan suatu solusi dalam bentuk persamaan periodik. Untuk lebih memahami penyelesaian masalah nilai batas pada persamaan diferensial Mathieu-Hill diberikan salah satu contoh aplikasinya dalam menghitung getaran pada mesin lokomotif kereta yang dimodelkan dalam bentuk persamaan diferensial Hill-Meissner
Penyelesaian Persamaan Telegraph Dan Simulasinya
Get PDFEquation Telegraph is one of type from wave equation. Solving of the wave equation obtainable by using Green's function with the method of boundary condition problem. This research aim to to show the process obtain;get the mathematical formula from wave equation and also know the form of solution of wave equation by using Green's function. Result of analysis indicate that the process get the mathematical formula from wave equation from applicable Green's function in equation which deal with the wave equation, that is applied in equation Telegraph. Solution started with searching public form from Green's function, hereinafter look for the solving of wave equation in Green's function. Application from the wave equation used to look for the solving of equation Telegraph. Result from equation Telegraph which have been obtained will be shown in the form of picture (knowable to simulasi) so that form of the the equation Telegraph
Rumus Indeks Ketidaknyamanan Suatu Wilayah
Get PDFIndex of discomfort can be determined, this value is to accommodate everyone at level how humans are considered to be comfortable on a place. There are three who wrote formulas i.e., Discomfort Index (DI), temperature Humidity Index (THI) and Comfort Index (CI). In addition to air temperature, air humidity, wind speed there that affect the comfort of a place, such as the density of buildings, distance to the center of the industry, the distance to the center of the trade, the distance to the main street, the coverage of vegetation in the area of the settlements
Pewarnaan Simpul Dengan Algoritma Welch-Powell Pada Traffic Light Di Yogyakarta
Get PDFTraffic congestion is a problem which is often found in big cities in Indonesia. This requires a range of solutions, one of them with the settings of the traffic light. Traffic light arrangement can be completed with graph theory. Part of graph theory a graph coloring is used. Staining graf three i.e. coloring is differentiated into a knot, staining the sides, and staining region. This research examines the arrangements about traffic light using colorization algorithm Welch knot with Powell. The intersection of Data represented in the graph, which is then solved by coloring the vertices, then look for the value of the effective duration of the time compared to a traffic light settings occur at several intersections in Yogyakarta. Completion of traffic light arrangement using staining nodes provide alternative solutions duration lit the red light and green light is more effective than the secondary data at several intersections in Yogyakarta
Model Matematika Untuk Kontrol Campak Menggunakan Vaksinasi
Get PDFMeasles (also known as Rubeola, measles 9 day) is a highly contagious virus infection, characterized by fever, cough, conjunctiva (inflammation of the tissue lining of the eye) and skin rash. The disease is caused by infection of measles virus paramyxovirus cluster. It is a deadly disease. Vaccination is the most effective strategy to prevent the disease. It is generally given to children. This research aims to establish a model of the effect of measles vaccination, forming the point of equilibrium and analyze the stability, create a simulation model and interpret them, and to know the design to optimize the vaccination coverage required, so it can reduce the spread of this disease. This research was conducted by the method of literature study. It is expected to provide an overview of the mathematical model used to control measles vaccination with division of classes SEIR. The steps taken is identifying the problem, formulating assumptions to simplifying the model, making the transfer diagram, defining parameters, determining the equilibrium points and analyzing the stability, simulating the model, and forming the design to optimize the vaccination. Then from this research can be obtained free balance point of endemic and diseases and their stability. Based on the results obtained, the simulation is done by taking the data in Yogyakarta, and obtained vaccination coverage with two doses that can increase the herd immunity with lower vaccination coverage
Analisis Portofolio Optimal Saham Syariah Menggunakan Multi Index Models (Periode: 04 Januari 2010 – 1 Juli 2013)
Get PDFThe portfolio is a combination or aggregation of two or more individual stock and concern for investors is to form the optimum portfolio and one of the ways that can be used are Multi-Index Models (MIM). This Model is a development of the Single Index Models (SIM), if on a SIM only consider one factor that affects the value of the stock, then return at MIM considers more than one factor. This study discusses the optimal portfolio analysis using Multi-Index Models with a case study on the stock of the Sharia Jakarta Islamic Index (JII) period 4 January 2010 – 1 July 2013 by using composite stock price index (IHSG), index Dow Jones Industrial Average (DJIA) and index the Hang Seng Index as a factor in MIM. The results of this research were obtained that the optimum portfolio is a portfolio that was created based on the stocks that had the highest positive return value, i.e. UNVR 41,40%, SMGR 40.66%, KLBF 11.01, and LPKR 6,93% with a value of expected return portfolio amounted to 2.55% and risk of a portfolio of 0,29%
