- 1. Forecasting By Vector Autoregression Models CHAPTER NINE FORECASTING BY VECTOR AUTOREGRESSION MODELS 9.1 Vector Autoregressive (VAR) Models Vector Autoregression (VAR) models were introduced by the macro– econometrician Christopher Sims (1980) to model the joint dynamics and causal relations among a set of macroeconomic variables. The vector autoregression (VAR) is commonly used for forecasting systems of interrelated time series and for analyzing the dynamic impact of random disturbances on the system of variables. The VAR approach sidesteps the need for structural modeling by treating every endogenous variable in the system as a function of the lagged values of all of the endogenous variables in the system. The vector autoregression (VAR) model is one of the most successful, flexible, and easy to use models for the analysis of multivariate time series. It is a natural extension of the univariate autoregressive model to dynamic multivariate time series. The VAR model has proven to be especially useful for describing the dynamic behavior of economic and financial time series and for forecasting. It often provides superior forecasts to those from univariate time series models and elaborate theory–based simultaneous equations models. Forecasts from VAR models are quite flexible because they can be made conditional on the potential future paths of specified variables in the model. In addition to data description and forecasting, the VAR model is also used for structural inference and policy analysis. In structural ... Get more on HelpWriting.net ...

Conservation of Linear Momentum Name Institution Table of contents Objective 2 Results and Graphs 2 Discussion 3 Summary and Conclusion 3 References 4 Data Sheet 4 Sample Calculations 6 Conservation of Linear Momentum Objective The primary goal of this experiment was to study the force that a jet generates on hemispherical, flat, and conical surfaces. Further, the experiment exposed students to the concept of linear momentum conservation by observing forces that a jet of water exerts on objects with different shapes. Results and Graphs Figure 1: Forces Acting on the x and y axis As can be seen, the forces that act on the x–direction are caused by pressure at sections 1 and 2. Similarly, an expression that relates the conservation of linear momentum in the Y– direction can be developed. Discussion Although the experiment was successful, some errors occurred during the experiment that made most values to deviate from the expected ones. Generally, both fixed and random errors were observed (Mitchell & Worledge, 2015). The random errors, in this case, resulted into statistical fluctuations in the measured data because of the limitations in precision measurement. Additionally, the random errors occurred due to inability to take the same measurements as the expected ones. Furthermore, fixed errors were responsible for reduced inaccuracies in the values obtained (Valiani & Caleffi, 2011). However, the best way to minimize random errors is by averaging ...

This causes Crispin's character to become powerless, cautious and worrisome, and religious. The Middle Ages was a time of hierarchy, so unless you were born into a family of nobles, you were a powerless peasant. In the novel, Crispin is a serf, the lowest rank of peasants, and suffers from many hardships because of it. With being serf, your rights are stripped away from you, leaving you completely powerless. Masters are allowed to anything they wish and if they disliked you, they were able to make false accusations against you.

However, despite the uncommitted crime, Crispin has no control over the issue since to Aycliffe, Crispin is nothing more than an object–causing Crispin to be powerless. In addition to being powerless, being serf has also caused Crispin to become very cautious of others. He's often treated as an object, and doesn't receive much respect. He, "...had few friends and none I completely trusted. As 'Asta's son', I was oft the butt of jests, jibes, and relentless hounding" (Avi 13). Crispin and his mother are both serfs, and are looked down upon. Many people dislike Crispin mainly because of the relation he has to his mother. As a result, many people often taunt Crispin and alienate him– causing him to have difficulty in trusting people, and to be very cautious. For instance, Father Quinel instructed Crispin to meet him at Goodwife Peregrine's house. However, while on his way, Cerdic comes and tells him that there was a change in plans, and that Father could no longer meet him. This left Crispin at disbelief and was, "not certain I should trust the boy, but unsure what to do, I stood where I was" (Avi ... Get more on HelpWriting.net ...

- 12. Measuring The Load Pattern Of Measuring A Minimum Of Two... In some cases, lateral force shapes result to good approximation of demand displacements. Nevertheless, there has not been found any constant loading for exact approximation of local mechanisms and plastic hinges. Earthquake codes have made it mandatory to use a minimum of two lateral load patterns in nonlinear static procedure. These two load patterns are chosen to cover resulting forces in actual dynamic response of the structure. There are two load patterns which are used mostly in usual studies: uniform and modal load pattern. When using uniform load pattern, called also constant acceleration pattern, lateral forces applied to the structure are proportional to the mass of the building stories. This load pattern emphasizes on bottom floors demands more than top floor demands. It also increases the importance of shear in stories against overturning moment while modal load pattern emphasizes overturning moment and story demands. The FEMA356 code allows using comparative load pattern instead of constant load pattern. In this method the load pattern varies by plastic hinges as the displacements in the structure increase. Obviously, none of these shapes of constant loading can perform redistribution of inertia forces which occur with the first local mechanism and change of dynamic properties of the structure. Therefore, it is interesting to find a load shape which is closer to the variation of inertia forces distribution and gives a better approximation of the behavior of ...

It is recognized as an alternative method to field oriented control (FOC). Industrial drives with DTC are present in the market today.DTC is proposed to control electromagnetic torque and stator flux by directly modifying the stator voltage in accordance with the torque and flux errors DTC has added advantages over FOC absence of mechanical transducer, no requirement of co–ordinate transformation ,and a very simple control scheme with less computational time Though DTC is simple and have fast transient response, it generates high level common mode voltage variations. To avoid the problems of common mode voltage variations a new DTC algorithm was developed, in which, only odd or only even voltage vectors will be applied in each sector in which stator flux lies without using any zero voltage vectors. However, this method gave torque ambiguity. To overcome the torque ambiguity, modified DTC algorithm has been proposed The variable switching technique is a part of the conventional DTC technique .

In this paper we define different matrices associated with the Graphs along with some properties of a graph. And Rank of rank of an incidence matrix. Key Words: Adjacency matrix, Incidence matrix, Degree matrix, Circuit matrix and Line graph. INTRODUCTION: Incidence Matrix is one of methods of representing the graph. Let G = (V,E) be graph whose vertices and edges are labeled as v_1,v_2,........v_n and e_1,e_2,........e_m. An incidence matrix B associated with graph G of order n×m is defined by b_ij={█(1 if v_i is incident with e_j@0 Otherwise )┤ [4] The graph and its incidence matrix are shown as follows: The incidence matrix contains only two elements 0 and 1. Such a matrix is called a binary matrix or (0 1) – matrix. For a given any geometric representation of a graph without self–loops we can easily write its corresponding incidence matrix. On the other hand if we were given an incidence matrix B we can construct a graph without any difficulty. The graph and its incidence matrix are simply two alternative ways of representing the same graph. [1] PROPERTIES: Some observations of incidence matrix and it's graph.

AAV vectors have been widely used in clinical trials to deliver therapeutic genes to mutated ones, and are efficient and safe in vivo application3. However one major drawback is the limited packaging capacity for genes with larger sizes 3. Fortunately, this can be overcome with the treatment of the dystrophin gene (DMD), which encodes the cohesive protein dystrophin that supports the cytoskeleton of a cell3. There are two methods can be used with AAV vectors to decrease the duration of epilepsy: inducing somatostatin into AAV vectors and direct injection of glial targeting AAV vectors. Method 1: Somatostatin (SST) is a neuromodulator known to have diverse functions in sleep and motor activity and it plays a putative anticonvulsant role, such as in maintaining hippocampal homeostasis4. Some studies have suggested that AAV vector–mediated expression of SST suppresses hippocampus related seizure development in rats4. Viral vector gene therapy using SST as an anti–seizure–related neuropeptide in a kindling model of epilepsy was implemented, where over successive electrical stimulation of the same intensity, seizures evolve from partial to generalized states 4.

What advantages and disadvantages did the group gain through the streamlining of business? Do you think, as of 2009, the Group is still present in too many businesses? Answer There were a total of 84 companies in several industries under the Tata Group in the early days. With the vision of the new leader, he realized that there was a lot of irrelevant businesses in the group that did not contributed much to the group's profits and as a result he streamed line and exited a lot of the industries in which the group was not doing well, in order to accomplish his vision and goal and make the group stronger. In my opinion, this was a good move as the benefits outnumbered the disadvantages. The stream lining made it possible for the group to manage the companies easier. In addition, they were able to cut costs by having a smaller workforce and fewer overheads. Importantly, they improved productivity in the group by eliminating some unnecessary ventures and focusing more resources in certain areas, thus improving revenue.

Video Games Are The Most Revolutionary Form Of Art To quote the famous game designer Santiago Sir "Games are not just art, they are the most revolutionary form of art mankind has ever known about". Video games are a hybrid form of art that brings together multiple forms of art. Video games are very aesthetic. They achieve this through the use of their realistic graphics, in depth development of the story, and the emotional attachment built overtime with the game. Video games have come a long way in the development of the graphics system. To really understand the substantial innovations that have been made, one needs to understand where the original graphics started. The original video games used vector based graphics, which uses geometric primitives to produce an image. This was common for arcade games. These vector based graphics were mainly two dimensional and had little detail. For the time that these games released it was an amazing feat of art that they could use math to produce these images and have a reaction through the use of a joystick and buttons. Video games of the modern time we live in have blown this feat of the past out of the water. The common form of producing graphics in a video game now uses resolution based bitmap graphics to develop images.

- 49. Leadership And The Life Cycle Of A Group . A Group Is A Leadership and the Life Cycle of a Group A group is a living thing, developing over time and adapting to the environment and expectations imposed upon it as it grows. When observed carefully, a pattern of distinct phases emerge in this growth process. It is important to recognize and take advantage of these various stages of development in order to maximize group effectiveness and efficiency. There are several different models for small group development, but Tuckman 's model is "probably the most famous sequential–stage theory" (Johnson & Johnson, 2016, p.27). This paper will discuss the five stages of group development according to Tuckman 's model as well as some practical leadership guidelines that will help a group remain effective ... Show more content on Helpwriting.net ... Of great value at this stage is encouragement and patience. The reason for the conflict is generally insecurity (Bonebright, 2010, p. 114), so providing a strong support system an reassurance can help move a group to the next phase. As members of the group begin to feel safe and secure, the conflict will settle and the group will develop a bond and unified goals. Labeled a period of norming, it is "characterized by close relationships and cohesiveness" (Group Development, 2003). In fact, this stage is so characterized by relationship that it could almost be viewed as a honeymoon phase. Group members will frequently set aside differences and unity becomes a priority. It is important at this stage to emphasize honesty and creativity because the group will likely be trying so hard to be amenable that some members may hold back. Others will be ready to open up given their newfound sense of security within the group. This is also a critical time for the group because it typically delineates a time to commit (Johnson & Johnson, 2016). If a group reaches this stage and not all members are on board, it may hinder progress. Once a group has developed cohesiveness, it will truly begin to produce. This phase of effectiveness is titled performing according to Tuckman 's model.

- 51. The Effects Of Climate Change On Development And The... Human survival is dependent on myriad things, the first of which that come to mind are food, water and shelter. As the world has developed, the abundance of each of these has increased dramatically, especially in the developed world. However, along with this growing population and resource web has come a growing understanding of disease, and its impacts on the more–developed and less– developed parts of the world. Another effect of growing population is the concerning truth of climate change: changes in climate not only alter the environment, but can alter the range and distribution of diseases. Moreover, human population leads inherently to social networks and systems that can have significant impact on development and the spread of disease. These impacts can manifest as civil strife, or simply the unavoidable reality of proximity within a community. Lea Berrang–Ford, an Associate Professor at McGill University, has conducted numerous studies over the past approximately fifteen years that blend together the complex aspects of disease spread in general, choosing to focus mostly on African trypanosomiasis or "sleeping sickness", and how climatic and social pressures affect the spread of disease. Her work also extends beyond her own research, into her classroom, and through her students, out into the world.

- 53. Path Integration for Navigation Path Integration Forms of spatial sensitivity among organisms are exceedingly wide–ranging. Spatial sensitivity among lower animals has been studied in its role in navigation. Many of these animals exhibit extraordinary navigational capacities. Amoebae have light sensitivities that lead them to liquid areas that serve their chemical needs. Crickets locate mates using sound. Path integration, or dead reckoning, is one of the four types of navigation. I begin by distinguishing the differences among the four types of navigation. I continue by explaining in more detail the second type of navigation: path integration. Next I explain why one might think that certain types of path integration are not representational. Last I show why path integration doesn't depend on perceptual constancies. Path integration is one of the four types of navigation. The other three are beaconing, landmark use, and map use. Organism's can travel toward or away from a source of stimulation. Beaconing, or homing, is an organism's movement toward a target. That movement is in response to a stimulation that derives from the target's location. Beaconing allows organisms to move in directions that are favorable to them. For example, salmon travel in the ocean for years. After a couple years, they return to their home streams in straight a line. This is a result of them responding to certain hormonal changes. Many organisms use another type of navigation called landmark use. Landmark use ... Get more on HelpWriting.net ...

CHAPTER 1 INTRODUCTION Definition of Differential Equation A differential equation is an equation which consists of derivatives or differentials of one or more dependent variables with respect to one or more independent variables (Abell & Braselton, 1996). Differential equation generally can be classified into two, which are ordinary differential equation and partial differential equation. If a differential equation consists of ordinary derivation of one dependent variable with respect to only one independent variable, it is known as ordinary differential equation. Meanwhile, if a differential equation consists of partial derivative of one or more dependent variables with respect to more than one independent variable, it is known as partial differential equation. Ordinary Differential Equation In general, an ordinary differential ... Show more content on Helpwriting.net ... It is simply expressed as the matrix product of two factors, a variable vector with a constant matrix, x ̅(t)=Hv ̅(t) 1.6 , where H is a constant matrix and v ̅(t) is a time–variable vector. This approach, using the matrix theory, gives a numerical solution to the systems of homogeneous or non–homogeneous of linear differential equation with constant coefficient. Any systems of linear differential equation which can be solved by Laplace Transformation can also be solved by this approach. Problem Statement The basic approach recalculates the partial fraction expansion coefficients of a rational function from the very beginning whenever the initial conditions are changed, which is very time– consuming. This study finds an alternative approach to compute the solution with a minimal and straightforward effort of re–computation upon the initial conditions changed. Objective of ...

Gill† Elizabeth Wong† UCSD Department of Mathematics Technical Report NA–10–01 September 2010 Abstract Computational methods are considered for ﬁnding a point that satisﬁes the secondorder necessary conditions for a general (possibly nonconvex) quadratic program (QP). The ﬁrst part of the paper deﬁnes a framework for the formulation and analysis of feasible–point active–set methods for QP. This framework deﬁnes a class of methods in which a primal–dual search pair is the solution of an equality–constrained subproblem involving a "working set" of linearly independent constraints. This framework is discussed in the context of two broad classes of active–set method for ... Show more content on Helpwriting.net ... This reformulation gives the primal–dual search pair as the solution of a KKT–system formed from the QP Hessian and the working–set constraint gradients. It is shown that, under certain circumstances, the solution of this KKT–system may be updated using a simple recurrence relation, thereby giving a signiﬁcant reduction in the number of KKT systems that need to be solved. The linear constraints of a QP may include an arbitrary mixture of equality and inequality constraints, where the inequality constraints may be subject to lower and/or upper bounds. Many mathematically equivalent formulations of the constraints are possible, and the choice of formulation often depends on the context. We consider the generic quadratic program minimize n x∈R 1 ϕ(x) = cTx + 2 xTHx subject to Ax = b, Dx ≥ f, (1.1) where A, b, c, D, f and H are constant, H is symmetric, A is m × n, and D is mD × n. (In order to simplify the notation, it is assumed that the inequalities involve only lower bounds.) However, the methods to be described can be generalized to treat all forms of linear constraints. No assumptions are made about H (other than symmetry), which implies that the objective ϕ(x) need not be convex. In the nonconvex case, however, convergence will be to local minimizers only. In Section 4, the nonbinding direction method is extended to problems ... Get more on HelpWriting.net ...

The History Of Sytech And Gene Therapy All you need to know about Gene therapy Sytech– Curing the future The history of SyTech and Gene therapy Gene therapy was introduced in 1985 by SyTech and has been the main priority of the company ever since due to its promising future in science. One of the first human gene therapy procedures involved injecting the correct ADA gene to a four year old girl with the ADA deficiency. Due to the success of the procedure, the patient is now living a healthy life. The success marked an important landmark in human history, one that has the potential to change the future. What is gene therapy? In short, gene therapy is a method in which DNA Is used to fix a genetic problem. These problems can include missing or genes that don't work. The right genes are delivered to the cell via harmless viruses for their provirus properties. The viruses then insert the good copy of the gene into the patients DNA where the cells machinery reads the information like a manual and makes RNA proteins so when it divides, ideally, the problem will be fixed. There are two types f gene therapy: Germline (targets egg/sperm cells; stops disease in its tracks) and somatic (targets somatic cells; after the disease is active).The methods for gene therapy that are being tested include: Replacing the non working copy of a gene with a healthier one Bringing new genes entirely for those that don't exist Bring a new gene to fight/fix the disease.
