With her article “Faced With a New Tax, Berkeley Drinks Less Soda,” published in The Upshot of the New York Times on August 25, 2016, health care reporter Margot Sanger enters a fierce debate about the impact of the soda tax on the consumption of sugary drink. Since 2014 when the tax first went into effect in Berkeley, California; attempts to impose the tax have been a matter of public controversy, and this is what motivated Sanger to produce this piece. The story’s “Kairotic moment,” as…

hard to solve. TSP consists of salesman and N cities, the goal of this problem is to visit each city by the salesman once with minimum tour length. The challenge in TSP is to find the route that has minimum distance. TSP can be presented via complete graph as follows: G = (V, E). Where V is the set of vertices which is equal to the number of cities and E is the set of edges between cities, each edge assigned the distance between any two cities…

certain branch of a network. A path is a trail in which all vertices (except possibly the first and last) are distinct. This is a glossary of graph theory. Graph theory is the study of graphs, systems of nodes or vertices connected in pairs by edges. The degree of a vertex in a graph is the number of edges incident to it. The formula implies that in any graph, the number of vertices with odd degree is even. This statement (as well as the degree sum formula) is known as the handshaking lemma.…

In each scenario mentioned in previous section, we formulate network topologies as undirected graph $\mathcal{G}=(\mathcal{V},\mathcal{E})$ with $n$ nodes and $m$ edges having demand at a node $i$ in $\mathcal{V}$ given by $d_i$. Here, $\mathcal{V}$ indicates set of nodes and $\mathcal{E}$ indicates set of edges in the topology. A link would exist in the topology between node $i$ and node $j$, if they are in the communication range of each-other satisfying constraint, \begin{equation} P_i…

you not know before? I actually did know some of these items, or at least the terms, previously but not in the sense that they were presented to us this week. I was familiar with vertices, edges, and the formal notation of a graph. I didn’t have an appreciation for how graphs could be applied to creating and managing associations with various items by applying them as vertices or edges in a way beyond their representation as numeric coordinates. • What information was contrary to what you…

acceptors. Thus, the goal of this experiment was to determine whether E. coli has a direct motion or random motion when a chemoattractant (glucose) was present. This was done by observing the velocity before and after the chemoattractant and by making Log-Log Plot. Theoretical Chemotaxis refers to the ability of organisms to move in response to the presence of a chemical. The movement of organisms could be either attractant in the same direction as chemoattractants , or it can repel the…

Multicollinearity Multicollinearity is one of the common problems in spatial regression analysis. Sometimes some or all of the explanatory variable are highly correlated in the sample data, which means that it is difficult to tell which of them is influencing the dependent variable (Barrow, 2009, p. 306). Hence, to check whether the independent variables are correlated with each other, a correlation matrix for the three indicators was measured using excel. The correlation matrix in table 2…

choose to use three different methods: Interactive log, unobtrusive measure, and individualized rating scale. I choose each method for various reasons. First, focusing on the target behavior of reducing angry outburst towards his spouse, I decided to use an interactive log to help the client track when these outbursts were occurring and to identify what elements may be influencing the occurrence of this unwanted…

It is my understanding that logs is defined as the inverses of exponential functions; therefore, we can essential use Theorems to inform our understanding. The fact that the domain of a log function is the range of an exponential function, and that the range of a log function is the domain of an exponential function was very difficult for me to understand because similar concepts were dealt with…

and graphing. The primary goal of the practical was to determine the pKa value of a weak acid. The Ka is an acid dissociation constant, it is a quantitative measure of the strength of an acid in solution. The pKa is defined as the negative log of the Ka, pKa= -log Ka. The lower the value for the pKa the more acidic the acid (greater concentration of H+ ions). The pKa of a compound relates to how likely, at a given pH, the compound will be ionized. The Henderson-Hasselbalch equation is used to…
