...like it or not, machines will play an important part in the future. They already play such a large role in our life, it’s almost inevitable. Over the past 20 years, the use of computers has skyrocketed. Now there is almost one in every home. Children of this generation are being taught to use computers at a very young age. Computers are used in most every office, also. Jobs that used to be done by men can now be done by machines. Technology is growing each day. Jobs are being replaced by machines, and there is more need for people familiar with computers or technology. In a lot of cases as far as jobs etc go, it’s something you need to know or something that helps considerably. Technology is becoming more advanced. As the technology changes, so do our lives in a small way and it shall continue into the future. Technology has changed our lives for both better and worse. It has made life so much easier. Now instead of baling the hay themselves, farmers can put the hay into a machine that makes bales. It is not only more efficient, but the outcome is much more desirable. Laborious jobs have been reduced or eliminated. Though it has made life easier, it also has promoted laziness. Instead of using our physical ability to accomplish a job, so many can now be done by machine. Rather than walking to the store to pick up margarine most would drive to the store. Little things that are so easily accomplished by hand can now be done mechanically. We’d rather have a machine do the job, than...

...Machine learning According to Alp Aydin (2010), Machine learning is an area of artificial intelligence that developed from design acknowledgment and computational learning hypothesis. It investigates the study and development of calculations that can gain from and make expectations on information. Such calculations work by building a model from sample inputs keeping in mind the end goal to settle on information driven forecasts or choices, as opposed to taking after entirely static project guidelines. Machine learning is firmly identified with computational statistics; a specialty that goes for the configuration of calculation for executing factual techniques on computers. It has solid ties to numerical enhancement, which conveys techniques, hypothesis and application areas to the field. Machine learning is utilized in a scope of registering errands where outlining and programming unequivocal calculations is in feasible (Marshland, 2009). Concepts of machine learning 1. Bayesian networks A Bayesian network is a probabilistic graphical model that speaks to an arrangement of irregular variables and their restrictive independencies through a coordinated non-cyclic chart. For instance, a Bayesian system could speak to the probabilistic connections between forex market and political unrests. Given the instances of political unrests, the system can be utilized to figure the probabilities of the forex market dropping. Proficient calculations exist that perform surmising and learning...

...Should we be the machines’ allies? History is repeating itself in another different way, let me explain. The industrial revolution affected the society in many ways-‐ positively and negatively. People were afraid of lose their jobs for the machines; technological progress was a threat for them, especially for textile workers. However, labor’s share of GDP remained constant throughout this era -‐ this happened because the high productivity of the machines dropped the prices of products become them cheaper and easier accessible to the workers; real income increases as firms could pay more to the employers-‐ men and women. Now, in the New Machine Age 1 what is happening is that people are being replaced by computers and new technologies that are more productive and cheaper than humans. As such, unemployment are increasing in much of ...

...PROFILE A washing machine is a domestic appliance powered by a fractional horsepower (FHP) electric motor to wash clothes and household linen and dry clothes. The capacity of the washing machine is determined by the weight of the dry clothes it can wash at a time and is expressed in kgs. 3.2. SEGMENTATION: Washing machines can be segmented on the following bases: 3.2.1. Functions- Washing machines can be classified as washers, semi automatic and fully automatic machine on the basis of their functions. * Washers: Washers are simple machines, which wash clothes but do not dry them. They are minimal in functions and are mainly manufactured in unorganized sector. These are single tub machines and are very low in price. These machines are becoming obsolete in the urban areas due to their inefficiency in performing certain functions. * Semi automatic or Twin tub: These machines have two tubs, washing tank and drying tank. They perform more function than the washers but the sequencing and duration of each stage of the process like washing, rinsing and drying operations have to be controlled manually. Clothes need to be physically transferred from one tub to the other. * Fully automatic: These are compact machines in which clothes are washed and dried automatically in a single drum. Depending upon the type of fabric and total weight of the clothes the wash combination is selected and the wash cycle is carried out automatically. Fully automatic washing machines require a continuous...

...STITCHING MACHINES A sewing machine is a mechanical device equipped with a needle (or needles) threaded at the point-end, which puncture the fabric periodically as it moves under the needle; each stitch is created as the thread loops onto itself (chain stitch) or locks around a second strand of thread (lockstitch), sewing the materials together. Sewing machines are used in both the home and industry, but are designed differently for each setting. Those for the home tend to be more versatile in terms of the number and kinds of stitches they can perform, but they operate more slowly than industrial machines, and have a shorter life span. Industrial machines are heavier, have a much longer life span, are capable of thousands of stitches per inch, and may be designed for very specialized tasks. Sewing machine is invented by Elias Howe in 1846 and successfully manufactured by Howe and Isaac Merritt Singer. Types of sewing machine systems -There are three types of sewing machine systems * Mechanical sewing machines * electronic sewing machines, and * computerized sewing machines Mechanical sewing machines are controlled by a rotary wheel. They have handles and disk to make changes in the tension or the length or width of the stitch. Electronic sewing machine has more features than the mechanical sewing machine. Instead of turning handles or disk, electronic sewing machines use buttons to adjust length or width of the stitch. Electronic sewing machines have motors;...

...Machine Learning Neural Networks - II 12.4.3 Perceptron Definition: It’s a step function based on a linear combination of real-valued inputs. If the combination is above a threshold it outputs a 1, otherwise it outputs a –1. x1 x2 w1 w2 wn Σ w0 X0=1 {1 or –1} xn O(x1,x2,…,xn) = 1 if w0 + w1x1 + w2x2 + … + wnxn > 0 -1 otherwise A perceptron draws a hyperplane as the decision boundary over the (n-dimensional) input space. + + + - Decision boundary (WX = 0) A perceptron can learn only examples that are called “linearly separable”. These are examples that can be perfectly separated by a hyperplane. + + + Linearly separable - + + + Non-linearly separable - Perceptrons can learn many boolean functions: AND, OR, NAND, NOR, but not XOR However, every boolean function can be represented with a perceptron network that has two levels of depth or more. The weights of a perceptron implementing the AND function is shown below.

...Simple Machines Experiment 9 – Simple Pulleys Introduction Simple pulleys are a form of simple machines that makes heavy loads easier to lift. They have a grooved wheel that is used for a rope or belt to ride, and allows a force that is acting on one direction, to be changed to another more useful direction. Types of simple pulley: • Fixed Pulley – A pulley that is stationary relative to the earth • Movable Pulley – A pulley that is allowed to move freely, being cradled by a rope or belt. • Compound Pulley – Is a combination of both of the previously mentioned types. Aims and Objectives • To test if tension in a pulley cord changes due to a change in direction of the cord. • To determine if the Mechanical Advantage (M.A) of a compound pulley system. Apparatus • 2 Adjustable hooks • 4 Knurled nuts • 2 Pulleys • 1 Single pulley block • 2 Weight hooks • 1 Set of weights • 1 10N Spring balance • 1 Cord – Approximately 600mm long Test 1 Results W(N) P(N) M.A = W/P 1 1 1 2 2 1 3 3 1 4 4 1 5 5 1 Test 2 Results W(N) P(N) M.A = W/P 1 1.1 0.91 2 1.9 0.91 3 3.2 0.94 4 4.1 0.98 5 4.7 1.1 Test 3 Results W(N) P(N) M.A = W/P 1 0.5 2 2 1.1 1.82 3 1.8 1.67 4 2 2 5 2.2 2.27 Test 4 Results W(N) P(N) M.A = W/P 1 0.6 1 2 1.2 1 3 1.7 1 4 2.3 1 5 2.9 1 Observations In test 1 the readings are the same for both the load (W) and the effort (P) due to the fact that fixed pulley was used for the experiment and so only the direction of the force of...

...Are we in a Race Against the Machine? For that answer maybe, we should ask the McDonald's employee who is slowly being replaced by a self-service kiosk. Or the Schnuck’s employee who found their hours cut due to the fact more and more people are using the self-checkout lanes. Technology has definitely made our lives more convenient, but that convenience comes at a cost. How many times have you used an app for curbside pickup for your food? Purchased clothes online? Ordered a pizza? Every time we make one of those purchases, we need to keep in mind that that was someone's job at some point. Machines will never be able to take over every job sector, but those low skill jobs will probably be a thing of the past in the not so distant future. What does all of this mean for those low skilled workers?...
