In the Python file, you will be creating a neural network to predict the price of a stock. Part of the program is already implemented, your goal is to set up the model, train the model on the training data set, then finally predict the values from the testing data set. You should create a Sequential model with 5 layers. Your model should use 2 LSTM layers, and after each use a Dropout layer with a rate of 0.2. The first LSTM layer should have input_shape as a parameter along with units set to 4. The final layer should be a Dense layer with units set to 1. Once the model is set up, you should compile it with a mean_squared_error loss and the optimizer set to adam. When you fit the training dataset, make sure to set the following values: epochs=5, batch_size=16, verbose=0 Finally, you should run the predict function on the x_test dataset and print the last column of the array along with the model summary..

Declaring a Pointer To define a pointer, use an asterisk, (*), in the declaration to specify the variable will be a pointer to the specified data type. Recall that the name of an array holds the memory address of the first element of the array. The second statement then would store the memory address of the first value in the variable valuePtr. The name of a pointer is an identifier and must follow the rules for defining an identifier. Some programmers place the letters ptr, a common abbreviation for pointer, at the end of the variable name, others prefix a pointer with p_ or ptr_, and there are those who do nothing to distinguish a pointer by its name. The naming of a pointer variable is a matter of programming style. Once a pointer has been declared and initialized, it can be used to access the data to which it points. In order to access this value, the dereference operator, *, must be used to prefix the name of the pointer. From the code above, valuePtr holds the address of the first element of the values array; therefore, *valuePtr will access the value 325. Add the following to main and execute the program. The output generated should look something like the following. Where 0xbfad43e8 is a memory address displayed in hexadecimal. Obtaining the Memory Address of a Variable The address operator, &, is used to determine the memory address of a variable that is not an array. Add code necessary to use fixed and setprecision, then add the following to main and run the program to confirm the use of the address operator. Using a Pointer to Alter Data Just as the dereference operator is used to retrieve data, so too is it used to store data. Add the following to function main and run the program. The pointer, ratePtr, is used to change the data stored in payRate. The output of payRate confirms the change. Using a Pointer in an Expression As previously shown, the value pointed to by a pointer variable can be retrieved by dereferencing the pointer. In the above code, the retrieved value was simply displayed to the screen; however, it can also be used in an expression. Add the following to main and execute the program. Pointer Arithmetic It is possible to add to or subtract from a memory address stored in a pointer. These actions can be accomplished using the addition operator,+, subtraction operator, - and the increment and decrement operators, ++ and --. This is helpful when accessing arrays via pointers. The increment operator has been used to add the value 1 to a variable. When used with a pointer, the increment operator adds the size of the data referenced to the memory address stored in the pointer, effectively moving the pointer to the next data value. Building on the code from above, add the following to main and execute the program. We initialized valuePtr to the memory address of the first element of the array values. Incrementing valuePtr instructs the computer to add four bytes, the size of an integer, to the memory addressed stored in .

Reaction Statistics Background When collecting experimental data from chemical reactions, it’s often useful to generate statistics based on the data. One experimental measure is the reaction rate in moles per second, representing the amount of product formed per unit time. If we have a set of these reaction rates collected in a data file, we can calculate summary statistical information, such as the minimum and maximum values, the arithmetic mean, variance, and standard deviation. Finding the minimum and maximum are straightforward: we scan through all the data, and keep track of the smallest and largest values encountered. The arithmetic mean (or average) is defined as: m = (X1+X2+…+Xn)/n where n is the number of reaction rates, and xi represents one experimental reaction rate. Once you have the arithmetic mean, the variance can be calculated as the mean of the squares of the deviations from the mean: v= ((Xn-m)^2+(X2 – m^2) + …+(Xn-m)^2)/n where n is the number of reaction rates, xi represents one experimental reaction rate, and m is the arithmetic mean of the reaction rates. Once you have the variance, you can calculate the standarddeviation as: s = sqrt(v) Assignment You will develop a C program that reads data from an input text file containing chemical reaction rates (in moles per second), and computes the minimum, maximum, arithmetic mean, variance, and standard deviation for that set of data. Your instructor will provide input text files, which will each contain a series of double values, each on a line of its own within the file. Your program will read one of these input files into an array of doubles (i.e., it will populate the array using the data values from the file). Your program will then calculate statistics using that array of doubles, and will write the results out to a separate output text file. The goals of this assignment are to provide you with experience reading and writing text data files, provide you with experience passing an array into a function, and give you more experience organizing your program into separate C functions. When defining your C functions, you may either: Define the functions before they are used by any other functions, OR Place function prototypes near the top of your code (after all #include directives), and then define the functions in any order. Part 1 – Opening Files and Reading Data Create a new Visual Studio Win32 Console project named reactionstats. Create a new C source file named project4.c within that project. At the top of the source file, #define _CRT_SECURE_NO_WARNINGS, and then include stdio.h, math.h, stdlib.h, stdbool.h, and float.h. Inside your main function, define the following: A one-dimensional array of 600 doubles. They do not need to be initialized to anything at this stage. An integer variable to hold the number of elements in the array, initialized using the approach demonstrated in class, using sizeof. A FILE pointer variable, which will refer to the input data text file..

In what ways did the evolution of an exoskeleton help insects be well-adapted for life on land? Select all that apply. Its impermeability to water allowed insects to move farther from water without dessicating It gave them the rigid structural support needed to survive the force of gravity away from water. It allowed them to breathe much more efficiently through their skins It allows them to grow larger indefinitely without any sort of metamorphosis or shedding.

in this case we chose the best option would be to work with the government but I want to summarize why this option is the best in the situation and gather the ethical reasoning and constraints behind it. H. B. Fuller and the Street Children of Central America The article was one of many published on street children in Latin American cities during the early 1990s. The issue on which it focused was one that children's advocates had brought to the attention of H. B. Fuller Company repeatedly over many years. The article On a sidewalk in San Pedro Sula, Honduras ... a lanky, dark-haired boy [is] sitting with arms curled around his folded legs, staring at the passing traffic. The boy, a nineteen-year-old named Marvin, has been sniffing glue for ten years. Once the leader of a gang of street kids, he now has slurred speech and vacant eyes. A year ago, Marvin began to lose feeling in his legs. Now he can no longer walk. He slides on his butt, spiderlike, through gutters, across streets, and along the sidewalks. Still loyal to their chief, the younger kids in his gang bring Marvin food, carry him to a news stand to spend the night, and make sure he has enough glue to stay high. ... Doctors offer no hope that Marvin will ever walk again. Toluene, the solvent in the glue he sniffs, is a neurotoxin known to cause irreparable nerve damage. ... In Honduras, the drug of choice for children is H. B. Fuller's Resistol, a common shoe-glue made with toluene. Toluene creates the high the children come to crave ... Sniffing the glue is so common ... that the common name for street kids is Resistoleros. 1 Marvin was not the only casualty of the toluene-based glue. Toluene, a sweet-smelling chemical used as a solvent for the ingredients in adhesives, destroys the thin layers of fat that surround nerves, causing them to die. Occasional inhalation will produce nosebleeds and rashes while habitual use produces numerous disorders including: severe neurological dysfunction, brain atrophy, loss of liver and kidney functions, loss of sight and hearing, leukemia, and muscle atrophy. Prolonged use can result in eventual death. For over a decade, thousands of homeless children throughout Latin America, but most visibly in Guatemala and Honduras, had become addicted to inhaling the glue. Many of them were thought to have died while many more were now severely disabled by blindness, diminished brain functioning and crippling muscle atrophy. H. B. Fuller had total revenues of $1.243 billion in 1995 , up from $1.097 billion in 1994. Profits had totalled $392 million in 1995 and $354 million in 1994. Founded in 1887, the company was now a global manufacturer of adhesives, sealants, and other specialty chemicals, and had operations in over 40 countries in North America, Europe, Asia, and Latin America. While 15 percent of its sales revenues came from its Latin American operations, those operations accounted for 27 percent of its profits, indicative of the fact that its Latin Amer.

In the vertebrate brain, each region is specialized in function. The forebrain, which contains the olfactory bulb and cerebrum, has activities that include processing of olfactory input (smells), regulation of sleep, learning, and any complex processing. The midbrain, located centrally in the brain, coordinates routing of sensory input. The hindbrain, part of which forms the cerebellum, controls involuntary activities, such as blood circulation, and coordinates motor activities, such as locomotion. Why might you expect to see a larger olfactory bulb and midbrain compared to the cerebrum in rayfinned fishes? What trends would you expect to see in birds and mammals? Why?.
