Download file to see previous pages For the numerical simulation, MATLAB was used, with the simulation being discretized in time with a step size of one quarter of the frequency for a progressive visualization of the pattern, (606).
The results of this simulation indicate that the induced activity of the sparsely distributed cholinergic neurons within the dorsal striatum leads to the identification of surrounding n-cells. The single-pulse activation induces abrupt spread and declining of spikes. The model used reveals characteristic pattern formations respective to the morphological structure of the activated cells. The figure basically shows the spatial pattern formation within the dorsal striatum of rats as a result of the cortical activation of cholinergic neurons. The distribution of active neurons is indicated by color pink while the distribution of inactive neurons is shown by color grey. The pink coloring is an indicator of the initial activation of the sparsely distributed cholinergic neurons. This can be shown by Fig 2a. On the other hand, the grey coloring indicates the ongoing inactivation process throughout the structure. This can be indicated by Fig 2d. Therefore, this figure presents the induced activity in the dorsal striatum of a art as a result of cortical activation of cholinergic neurons, ...Download file to see next pagesRead More

Toward a theoretical and substantial understanding of complex social networks
...? TOWARD A THEORETICAL AND SUBSTANTIAL UNDERSTANDING OF COMPLEX SOCIAL NETWORKS By Location Social networks offer a wide range of behaviors that can be assessed and classified according to random and small-world network characteristics. In many cases, understanding these behaviors within the context of network models holds considerable promise for understanding, predicting and mitigating threats to both natural and man-made network systems. Both random and scale-free networks can be used to explain systemic processes according to rules of connectivity, which can in turn be used to construct dynamic models based on the manner in which nodes seek out and link with other nodes. Concepts of preferential connectivity, fitness... and...

Financial modeling
...It is mainly used for determining the value of derivatives by considering a preliminary zero rate term structure and the movement of the yield by constructing a tree explaining the interest rates. This model can also be a single-factor or multi-factor. The Heath-Jarrow-Morton model It uses statistical data and processes to derive the value of the derivatives by considering preliminary zero rate term structure and the up and down movement of future rates. Hull-white model It is a single factor that uses the preliminary term structure of interest rates with the up and down movement term structure to construct a trinomial free of short rates. Equity pricing...

...Grand Nursing Theorist Report Helen Erickson Modeling/ Role Modeling Modeling/ Role Modeling Erickson was a diploma nurse graduate from Saginau General Hospital. She got her B.S. nursing and then a Masters in psychiatric nursing. Later she received a Doctorate in educational psychology. She wrote a paradigm and Grand theory for nursing which encompassed many mid-range theories and applied clinical practice, educational programs and research (Erickson, Tomlin, & Swain, 2005). The theory is named Modeling and Role Modeling. This paper will discuss the theory developed by Erickson as well as how the theory can be integrated into various...

At the time of the system development, system designers model the system user individuality to be captured with the discrepancy of the user interface (Martínez-Normand, 2007). Developing User Model In this section I will develop a user model for a particular user. Here we will assume that person facing difficulties in using a computer. Here I will create a user’s simple profile that could be applied to that person. Aspect of user Score / 10 Comments Handling User...

Modeling Evaluation
...A Review of a Structural Equation Modeling Process Structural equation modeling (SEM) is a statistical modeling technique that provides a comprehensive approach to research questions (Burnette & Williams, 2010). SEM is becoming increasingly more popular in researches that involve the behavioral sciences because of its ability to specify and test linear relationships among variables. Oftentimes, a simple bivariate experiment is not a feasible option when researchers investigate human behavior in its natural setting (Haar & Brougham, 2010). Furthermore, researchers in the areas of organizational behavior, management, business, and applied psychology are often interested in multivariate...

Database Modeling
It might be important to have alternative contact addresses for students in case of unexpected situations. Therefore, in order to cater for such a situation, we need to create additional tables to handle the addresses. One table named email-address will contain the following fields: id, email address and student-id. Likewise, another table named phone-number will be created containing the following fields: id, phone number, and student-id. Finally, another table will be street-details. This table will have the following fields: id, street-name, city-name, state, and student-id. The four tables created to satisfy the requirements of 1NF. They are also in 2NF since they do not contain any partial dependencies. All fields in each tab...

Networks
...First Networking In the computing environment there are various types of networks which a person can interact with almost on a daily basis. These types of networks are majorly governed by the span that they cover. The first type in this case is the Local Area Network. This is network type that covers a small area like the office environment or school. It is majorly used in communication between the various departments that are there in the organizational building. The other type is the Metropolitan Area Network which covers a wider geographical region like a city for example. It is this type of network that enables the...

ARIMA modeling
...ARIMA Modeling of Costco Company Cost Revenue In the above graph of Costco Company’s revenues exhibits an upward trend. This means that the firm’s revenue exhibits an increasing trend as depicted by the graph. Under most circumstances, a firm whose revenue exhibits an increasing trend is regarded as an efficient and effective firm. However, revenues cannot be solely used to judge the performance of an organization. Therefore, it is not statistical exhaustible to conclude that Costco Company is efficient and effective on the basis of the upward trend of the revenue. This graph above shows that the spikes do not cancel-out that fast even though they come quickly within the red limits. In other words, the data for...

...Implied Variance for the Black Scholes Model Introduction The variance of security was determine using observation of historic price behaviour. Later, the black shoe model was used to determine the volatility implied in the variance. Actual values are used in place of other value and then the model is used to calculate the variance (Fengler 15) Discussion When we examine the Black Scholes model, we see that it would be impossible to manipulate the equation so that V ends up on the left-hand side all by itself. This forces us to use an iterative approach to solve for the volatility. The custom Black Scholes function that we constructed in the previous project makes it...
