Boolean logic, invented by George Boole in 1854, has helped create many systems and devices in the technological world. Such devices include ATM’s, thermal control systems, and alarm systems. Boolean logic contains only two values, true and false. A true value is represented by a 1 and a false value is represented by a 0. An important concept related to Boolean Logic is minimization of logic design. Minimization of logic design entails creating the simplest, most effective code to execute a system. This allows the program to be more efficient and easier to understand. Boolean logic is used to create truth tables. A truth table represents all the possible inputs and outputs of a given system. The number of rows in a truth table shows all possible …show more content…
The alarm system was based on a problem faced by a farmer. In order to protect his animals and his corn, the farmer needed an alarm that would be set when either the hen and fox were in the same barn or the hen and the corn were in the same barn. The farmer had two barns. The system would be programmed in LabVIEW where the alarm would be simulated by a digital LED light. Afterwards, the system would be applied to a NI-ELVIS board. The NI-ELVIS board had to be wired in a way that would once again turn an LED light on when either of the given conditions were true. In order to complete the objective, a truth table and Karnaugh map were formed. From the K-map, a simplified boolean equation was formed. The simplified boolean equation was necessary in forming a circuit needed to set the alarm off when the given conditions were met. Using the NOT, OR, and AND logic gates, a combinational logic circuit was designed. A combinational logic circuit is useful to engineers and technological innovators by making systems much more efficient. The combinational logic circuit produces a specific output (ex: setting an alarm off) based on combinations of inputs. Once the circuit was formed, the alarm was able to go off when necessary, aiding the farmer in protecting his animals and his …show more content…
Three switches were added and labeled hen, fox, and corn. Barn one was represented by the switching being up while barn two was represented by the switch being down. Three corresponding LED lights were also added and labeled the same way. Each grouping in the simplified boolean equation was attached to an AND statement. For example, the not corn and not hen were both wired to an AND statement. The results of all the AND statements were then connected to three separate OR statements. The final statement was wired to an alarm to turn on the LED light in LabVIEW. The system was tested in LabVIEW for all the
I then figured out when, what and where our lights were going to be on, off and what colour. Also sounding and V.O cues.
This section outlines and describes the various elements of the program logic model (see Figure 2). Our logic model is an important evaluative tool as it helps to explain the ideas behind the development of the DCD guidelines and the reasons why DCD programs will lead to positive outcomes in deceased organ donation.
My objective in this project was to produce a rat-trap powered catapult. It has a base of 30 cm by 30 cm, and has a theme of cows trying to escape the farm. The reason they want to escape is because they are being killed and turned into steaks, against there will. That is why I developed this ratapult, to save the cows. The cows also wanted me to ask you to eat more chicken.

A Cellular Automaton consists of a regular grid of cells, each as a finite number of states such as On and Off.An initial state [time t=0] is selected by assigning a state for each cell. The rule for updating the state of cells is the same for each cell and does not change over time.
The independent variables in this experiment are the time and the foils presented to the subject. The dependent variable is the discrimination index. The...
“I never trusted instruction manuals,” Mr. Rams said. “We all know that most people don’t read them.” He insisted that the operating systems of Braun’s products should be as simple and logical as possible. Buttons, dials and switches were arranged in an orderly sequence. Color coding was used for guidance: red for “off,” green for “on”...
Our project is how to train goldfish. We want to test the behavior of the fish. In the other we will just feed them. The constants are the tank, the amount of the goldfish, the feeding time, the rocks, and the days we clean the tank. In the experimental group we will have two fish and every time we feed them we will have two fish and every time we feed them we will ring a bell for 7-seconds. In the control group, we just feed the fish. We will condition the fish who know when they are being feed. In conclusion, our science fair project is
The research our experiment was founded on was that carried out by Taylor and Faust (1952). They carried out an experiment on 105 student’s, which was designed in the method of the game ‘twenty questions’. The students were split into teams of one member, two members and four members. They were then told that the experimenter would keep an object in mind whether it is animal vegetable or mineral was also stated, and they were then allowed 20 questions and guesses to reveal the identity of the object. In there experiment they found that the group of two members performed better than the group of four members in terms of how many guesses and questions it took them and how long it took them to deduce the identity of the object. However Taylor and Faust found that the efficiency did not differ in any significant way.
4. Only after the first beep goes and not before, must subjects start running. 5) When subjects 1-5 get to the opposite line (20 meters away) wait for second beep to proceed with beep test. 6)
Lastly, to wrap up, after living for a short 49 years, Boole is buried in the Church of Ireland. Boolean algebra and Boolean Logic are still around to this day and probably will be for many, many more years.
Flowers would show a color word like “yellow” and “blue” on a colored background. There was a pause with a blank screen, then the subjects were shown a two different colors that were half and half on the page, like yellow or blue. The subjects then had to indicate which color word initially was presented to them. “He did not investigate the influence of this paradigm on normal Stroop interference, however, and his task differs from traditional tasks in having a delayed, binary response”
Also the logical design lacks specific details such as technologies and standards and focuses on the general needs of the network. A logical design can be a view of any part of the network, whether it be the whole or just a part of it. Another element of the logical design is the IP addresses and their association with the different parts of the network. The IP addresses are assign to devices such as routers, switches, servers, workstations, and other devices that utilize the network. In the logical design we usually do not show the actual interfaces and physical cables in the diagrams; thus giving us the true meaning of the term "logical."
For the first experiment, two groups of participants were either randomly assigned to a cubicle with a diffused cleaner scent present, or to a control group where no diffused scent was present. Participants were then asked whether a string of letters appearing on a computer screen contained any real words by pressing either a "yes" or "no" button. Words were either cleaning related such as "cleaning" and "hygiene," or were control words such as "table"...
Words that have to do with logic like and, or, not are given symbols like &, V, or an upside down L reversed. The Letters X, Y, Z and so on are commonly used as variables and P, Q, R are used as predicates, properties or relations.
