Mass Spectrum Analysis of a Substance Sample Placed into Liquid Solution
(North Dakota State University, 2011)
Mass spectrometry is an analytical technique commonly used for determining elemental composition in a substance sample. For this purpose, the sample is placed into some liquid solution called liquid matrix. Unfortunately, ...
Modeling Loss Severity With Lognormal Mixtures
(North Dakota State University, 2015)
Property and Casualty insurance companies set premium rates by evaluating both loss fre-
quency and loss severity data. Insurance companies often model severity using a well-known single
distribution such as Lognormal ...
Investigating Statistical vs. Practical Significance of the Kolmogorov-Smirnov Two-Sample Test Using Power Simulations and Resampling Procedures
(North Dakota State University, 2018)
This research examines the power of the Kolmogorov-Smirnov two-sample test. The motivation for this research is a large data set containing soil salinity values. One problem encountered was that the power of the ...
Empirical Study of Two Hypothesis Test Methods for Community Structure in Networks
(North Dakota State University, 2019)
Many real-world network data can be formulated as graphs, where a binary relation exists between nodes. One of the fundamental problems in network data analysis is community detection, clustering the nodes into different ...
On K-Means Clustering Using Mahalanobis Distance
(North Dakota State University, 2012)
A problem that arises quite frequently in statistics is that of identifying groups, or clusters, of data within a population or sample. The most widely used procedure to identify clusters in a set of observations is known ...
Robust D-Optimal Design for Response Functions with a Downturn
(North Dakota State University, 2013)
Researchers studying dose-response relationships must allocate limited resources to design points in order to maximize the information gained from the study. D-optimal design is a well-described design that works efficiently ...
Optimizing Transportation Infrastructure and Global Supply Chain Integration for Nicaragua’s Autonomous Caribbean Regions through Network Modernization
(North Dakota State University, 2019)
The autonomous regions of the Nicaraguan Caribbean Coast are resource rich, yet they are among the poorest regions of Latin America. To realize economic growth and potential, this research examined Nicaragua’s primary-sector ...
Municipal Solid Waste Collection Route Optimization Using Geospatial Techniques: A Case Study of Two Metropolitan Cities of Pakistan
(North Dakota State University, 2016)
The population growth in many urban cities and its activities in developing countries have resulted in an increased solid waste generation rate and waste management has become a global environmental issue. Routing of solid ...
Impact of the Panama Canal Expansion in Global Supply Chain: Optimization Model for U.S. Container Shipment
(North Dakota State University, 2015)
The transportation of containerized shipments will continue to be a topic of interest in the world because it is the primary method for shipping cargo globally. The primary objective of this study is to analyze the impact ...
Derived Demand for Grain Freight Transportation, Rail-Truck Competition, and Mode Choice and Allocative Efficiency
(North Dakota State University, 2016)
The demand for grain freight transportation is a derived demand; consequently changes in the grain supply chain in production and handling, and those in the transportation domain will affect the demand for grain transportation. ...
