37 The Simple Linear Model (SLM) The SLM assumes a linear equation describes the conversion of total precipitation and total flow. The model was simply developed for the comparisons of models. When the precipitation and flow are in the same unit, the total of the discrete pulse response ordinates explains the gain factor G of the model as follows: G = ∑_(i=1)^m▒h_i^' .............................................................................3.47 Here, the gain factor (G) is the runoff coefficient and therefore defines the ratio of the total volume of the observed flow to that of the observed precipitation (Shamseldin et al, 1997). The conversion of rainfall to runoff is hardly linear. 38 The MODHYDROLOG Model MODHYDROLOG is a conceptual …show more content…
Clark translated all the flow to the outlet and then made corrections for storage by a single reservoir routing. For a single basin, the Clark model was modified by Dooge in 1959 to give the following equations for the hydrograph peak and its time: Q_p = V/T (1 - e^(-T/K) ).................................................................................3.49 t_p = T ...................................................................................................3.50 Where T is the base of the rectangular inflow and V is the volume of inflow (Singh, 1977). The ‘time’ in the time – area curve refers to the concentration time. In gauged basins, the time of concentration can be easily estimated from known rainfall – runoff data. In ungauged basins, empirical equations similar to those in the Rational method is used (Subramanya, 2002). The method shares the same flaws as the Rational method for PUB and is thus not suitable for the study
On pages 5-6, the diffusion coefficient of growth factor in water D is quoted from literature, whilst for growth factor concentration C*, duration of cells differentiation phase T, and the cell death rate Γwn were merely taken from personal communication with an independent laboratory. The rate of cell proliferation Γnw, cell differentiation Γud, solute uptake ΓR1 and Michaelis-Menten uptake K were selected to fit experimental observations received in the same manner. These data are proven [1, 2] to deviate between cell types and in response to culture environmental variations. Authors are advised to either publish detailed experimental data in the appendices, or consult reviewed articles, then assess the sensitivity of the model to different species and perfusion
1. Goal The objective of this lab was to create a Windows 2012 Datacenter Virtual Machine. On this virtual device, we were tasked with installing DHCP, DNS, and Active Directory services. This was very similar to lab 2 in that all of the core services had to be installed on this one device as with our RHEL7 server previously.
For Herbert Run the conductivity level was 687µS/cm. The Turbidity level was 0 FAU and the Nitrate level was 0.02ppm. I accept my hypothesis and reject parts of my hypothesis. I reject that both streams have a high turbidity level. Both streams’ turbidity level is zero.
Our group had to study Poliomyelitis and we each researched different parts to get data such as when the vaccine was created, how many people were infected the year before the vaccination, the number of infections this year, and so on. Our group project displayed obvious decay, whereas my individual situation was a slight decay. The graph of my individual assignment appeared linear because the rate was so slight. My indiviidual project was based on the decay of HIV/AIDS, but the number of new cases of HIV/AIDS only decreases very slightly each year in the U.S., .03% to be exact. I based my equation on the number of new cases in 2010 and 2012, which gave me the equation of y=47,500(.997)X. 47,500 was the starting number or the number of cases in 2010, I got the number .997 by subtracting the rate (.003) from the number 1, and the x represents a
1. How can the computer and the Internet increase a paralegal’s productivity? The computer and the internet increase paralegal’s productivity by giving them the ability to complete their work while they are away from their offices any time of the day or night. The use of technology is critical in a paralegal job about 75% of the job relates to computers.
Runoff, a common problem in many areas, has many causes. These causes, although sometimes avoidable,such as pollution, it can be repaired. As pollution and erosion, two of the main topics in this paper, affect the water quality, the agents aiding the processes are unstoppable. While agents are unstoppable, runoff is still controllable as far as the rate of runoff. When writing a paper such as this, the many information collected is shown in separate paragraphs, corresponding to the ideas.
The progressive era in the United States helped to spawn one of the first great conservative movements in the country. The conservative movement occurred as a result of the troubling theory that the fast paced urban development and industrial growth of the nation would lead to the extinction of wilderness areas in the United States. One of the most significant events during the era was that of the debate over the construction of the O 'Shaughnessy Dam in the Hetch Hetchy Valley located in California’s Yosemite National Park. After an earthquake crippled the city of San Francisco in the early 1900’s, the residents of the city recognized that they would require better-equipped ways to make certain that they had a steady supply of electricity and
The predicted and experimental responses are compared in order to validate the model and to calculate the prediction error. The prediction error was found to be below 7% indicating that the observed responses were very close to the predicted values. Percentage prediction error is useful in constituting the validity of generated equations and describes how close the predicted responses to that of actual values. The values of <15 are desirable to have closeness of the predicted values with the actual values
Observations have been made over the past week from September 11th through September 15th on subject x and their behavior. Three periods in a day subject x was examined. At the end of the week I made conclusions on subject x on who they are as a person. Many of the same behaviors were repeated over and over giving me a clear understanding of why they do what they do.
The multidimensional model of causality is a perspective that states abnormal behavior forms from multiple influences such as behavioral, biological, emotional, social and possibly developmental. Creating an example of a multidimensional model of causality is rather simple. I actually have a personal example of this multidimensional model. My freshman homecoming dance took an unfortunate turn. I was dancing with a guy when I did not feel very good at all.

Empirical Formula of Magnesium Oxide - Lab Report Background Information/Introduction: The aim of this lab is to determine the empirical formula of magnesium oxide by converting magnesium to magnesium oxide. As an alkali earth metal, magnesium reacts violently when heated with oxygen to produce magnesium oxide and magnesium nitride as a byproduct. In order to obtain only magnesium oxide, distilled water was added so that magnesium nitride will react and convert to magnesium hydroxide. Further heating then oxidizes all of the magnesium into magnesium oxide.
Happiness, sadness and nervousness, all of these are emotions that every single person will feel the experience during his or her life, everyone experienced love and hate in their heart. Hate is an acquired feeling and not a genetic. People are never born with hate, but they learned it by the environment that surrounds them, by the outside world. But why do people hate? What is are the reasons that drives them to hate, why would someone want to have that kind of gloomy bad intention about someone, because that would turn people to be more violence, after all, violence can led to death in some causes.
The drop rate was adjusted to 1 to 2 drops/second. 10.0 mL of the NaOH solution was allowed to drip away into a waste beaker. The exact volume of the sodium hydroxide solution used was determined.
Student Engagement A good teacher should know how to engage students in learning activities and be able to respond to diverse students needs in the classroom. The classroom observations I have seen these past week has shown me examples of good teachers. In all the classes I observed the students sat quietly and were always ready to raise their hands and answer questions. In my kindergarten class all the students were really into their assignments and wanted approval of their work from their teacher.
