contained results from a variety of computer applications in a number of different disciplines. Among the 121 studies were a substantial number on computer tutorials and computer simulations in science. The results from these early studies provide a good standard for gauging recent contributions of tutorials and simulations to science teaching‚ and are therefore reviewed here. Listed in the 1986 and 1991 reviews were achievement effect sizes from 37 studies of computer tutoring in college courses. Results

Why Conversation? Conversation is an important characteristic of chatbots. Let’s dive deeper into what a conversation is and why it’s important. Chatbots use Conversational User Interfaces (CUI) rather than Graphical User Interfaces (GUI). A GUI is a program that appears on screen and has graphical elements and pictures for mouse or touch interaction. CUI is text that a user types into a messaging app. Many of the chatbots available today are primarily text‚ but a chatbot can also use voice to interact

Computers In Military Applications Computers have given the modern military a degree of efficiency and effectiveness that has completely changed the way the military operates at sea‚ in the air‚ and on the ground. The fast computational abilities and the accuracy of digital computing enable the military to perform more quickly with less risk to themselves and with less cost to their government. Wars fought prior to the advent of digital computing could take years to complete and resulted

%FACE RECOGNITION SYSTEM % % Face recognition system based on EigenFaces Method. % The system functions by projecting face images onto a feature space % that spans the significant variations among known face images. The % significant features are known as "eigenfaces" because they are the % eigenvectors (principal components) of the set of faces. % % Face images must be collected into sets: every set (called "class") should % include a number of images for each person‚ with some variations

every one of us is on both sides of the wage exchange‚ in one way or another. We all know in a general way that wages have been rising for a long time in this country‚ but there is evidence aplenty that the economic principles which apply to wage problems are not well understood. Probably they are no better understood now than in the early thirties when measures adopted to combat the depression proved to be such colossal failures. Fearing

While the ultimate goal is the same‚ to determine the value(s) that hold true for the equation‚ solving quadratic equations requires much more than simply isolating the variable‚ as is required in solving linear equations. This piece will outline the different types of quadratic equations‚ strategies for solving each type‚ as well as other methods of solutions such as Completing the Square and using the Quadratic Formula. Knowledge of factoring perfect square trinomials and simplifying radical expression
