Your task is to write a function that takes in a 1-d Numpy array of actual initial values, a numeric weight scaler (between 0.9 and 0.99) and the number of previous time steps for prediction k, and return a numpy array of forecasted values for all values in that array starting with the k+1st one (we need to use the first k actual values to forecast the first observation). The idea here is that the most recent observation takes on a higher weight than less-recent observations in the data. Please use Numpy vectorization methods to solve the problem. .

Write an SML function groupdupes that takes a list of integers as its only argument. The function takes runs of values (i.e., consectuive, duplicated values) in the list, copying those runs into separate sublists, returning a list of those sublists. Examples: groupdupes([4,4,4,2,3,3,7,7,7,7,2,3,4,4,4]) would return [[4,4,4],[2],[3,3],[7,7,7,7],[2],[3],[4,4,4]] groupdupes([8,6,7,5]) would return [[8],[6],[7],[5]] Solution fun groupdupes_helper(L:int list, subL:int list, result:int list list) = if (L = nil) then result @ [subL] else if ( ( subL = nil ) orelse ( hd(subL) = hd(L) ) ) then groupdupes_helper( tl(L), hd(L)::subL, result ) else groupdupes_helper( tl(L), hd(L)::nil, result @ [subL] ) (* groupdupes Wrapper Function *) fun groupdupes(L:int list) = groupdupes_helper(L, nil, nil); .

You and another tech are discussing the relative merits of SCSI interfaces. You say that SCSI is dead, at least as far as drives go, and has been replaced by SAS and SATA. Your coworker says that SCSI has evolved and still has valid technical applications in todayâ€™s computing environment. Which modern applications does she say SCSI currently possesses? (Choose two.) A. SCSI now can use serial as well as parallel interfaces. B. SCSI now uses TCP/IP as a transport mechanism. C. Some motherboard manufacturers still market SCSI interfaces supporting PCI Express and PCI-X. D. SCSI Ultra-5 (parallel) now supports as 64-bit data width. Solution A. SCSI now can use serial as well as parallel interfaces. C. Some motherboard manufacturers still market SCSI interfaces supporting PCI Express and PCI-X. Although SCSI parallel (SPI) interfaces are still common, they are being replaced by Serial Attached SCSI (SAS), which retains the original SCSI technology but employs a serial design. Very few companies still market SCSI interfaces for motherboards supporting PCIe and PCI-X (PCI-X is a double-wide version of the PCI bus that satisfies the higher bandwidth requirements of servers). .

Write an application class (ArrayListApplication) that contains a main(...) method. The method must perform the following. • Prompt user for 10 names and store in an \"ArrayList\" object • Shuffle the names using \"shuffle\"\" method of the \"Collections\" class • Display the smallest element in the collection use the \"Collections.min\" method. • Display the largest element in the collection use the \"Collections.max\" method. Solution import java.util.*; public class ArrayListNames { publicstaticvoid main(String[] args) { int i; ArrayList<String> name = new ArrayList<String>(); System.out.println(\"Enter 10 Names \"); for( i=0; i<10; i++ ) { Scanner s =newScanner(System.in); name add(s.next()); } System.out.println(\"Initial collection : \"+name); // shuffle the list Collections.shuffle(name); System.out.println(\"Final collection after shuffle: \"+name); Object minimum = Collections.min(name); System.out.println(\"Minimum Element of ArrayList name is : \" + minimum); Object maximum = Collections.max(name); System.out.println(\"Maximum Element of ArrayList name is : \" + maximum); } } .

write a topic about RFID in SCM and what you have learned about adoption of RFID in SCM Solution RFID(Radio frequency identification) in SRM is a technology that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal, or person. RFDI is coming into increasing use in industry as an alternative to the barcode. The advantage of RFDI is that it does not require direct contact or line of sight scanning. It consists of three components - 1) Antenna, 2. Transreciever, 3. Transponder The term supply chain covers all possible processes involved in the flow of goods from manufacturing to customers including manufacturing, distribution and transportaion. RFDI technology is risen to become a revolutionary elament in supply chain management. It is not replacement for barcodes. RFDI is an innovative technology that will make the supply chain faster and efficient with less human error. There is a common trend when integrating the supply chain for many companies and provides a good model for better understanding of what the adoption of RFDI technology can do for supply chain network. there are many factors that maybe considered for adoption in RFDI in SCM like information technology - complexity, organization compatibility. Industrial organization - firm performance is enabled or constrained by industry structure. Resource based view- presence of resource that meet certain conditions, such as value, rarity, imperfect, imitability and lack of substituability. .

Write the C++ code for a function getInput which will read in an unknown of values from a file and store them in a one-dimensional array of integers. The function stores, in a reference parameter, the actual number of values it reads. The input file is declared and opened in main(), so the input filestream variable is needed as a function parameter. Write a C ++ function to find the minimum in a designated row of a 2-dimensional array which has 10 columns. The function parameters are the array, the row index of the row in which the minimum is to be found, and a reference parameter for the minimum value. Solution 4. #include<iostream.h> #include<conio.h> void min_row(int a[4][10],int row) { int m=a[row][0]; for(int i=1;i<10;i++) { if(a[row][i]<m) m=a[row][i]; } cout<<\"minimum number in row \"<<row<<\" is \"<<m; } void main() { int arr[4][10],i,j,r; clrscr(); cout<<\"Enter Element to the matrix\"; for(i=0;i<4;i++) { cout<<\" Row \"<<i<<\" :\"; for(j=0;j<10;j++) { cout<<\"Column \"<<j<<\":\"; cin>>arr[i][j]; } } cout<<\"\ Enter the row number\"; cin>>r; min_row(arr,r); getch(); } .

Write about the two sources of energy Write about the two sources of energy Solution Two sources of energy can be solar energy and wind energy Solar Energy Sun is the primary source of all energy. Light given by Sun, sunlight, is a clean and renewable source of energy. It is a sustainable resource which means it doesn\'t run out, but it can be maintained because the sun is always giving off energy. Coal or gas are not categorized as sustainable or renewable because once they are used, there is none left. More and more people have been using clean, renewable energy such as solar, wind, geothermal steam and others. It is called \'Green Power\' . Some Advantages of Solar Energy Some Disadvantages of Solar Energy Wind Energy Another source of renewable energy is wind. Wind can be described as the natural movement of air across the land or sea. To produce electricity, wind is used to turn the blades of a wind mill turns the shaft to which they are attached. This movement of the windmill shaft through a pump or generator produces electricity. Advantages Disadvantages .
