"Ladder" diagrams Ladder diagrams are specialized schematics commonly used to document industrial control logic systems. They are called "ladder" diagrams because they resemble a ladder‚ with two vertical rails (supply power) and as many "rungs" (horizontal lines) as there are control circuits to represent. If we wanted to draw a simple ladder diagram showing a lamp that is controlled by a hand switch‚ it would look like this: The "L1" and "L2" designations refer to the two poles of

. Moletronics is expected to touch almost every aspect of our lives‚ right down to the water we drink and the air we breathe. Experimental work has already resulted in the production of molecular tweezers‚ a carbon nanotube transistor‚ and logic gates. Theoretical work is progressing as well. James M. Tour of Rice University is working on the construction of a molecular computer. Researchers at Zyvex have proposed an Exponential Assembly Process that might improve

Programmable Logic Controllers or PLCs were developed in the late sixties by Bedford Associates of Bedford‚ Massachusetts to replace the hard-wired relay control systems used at the General Motors Hydra-Matic automatic transmission plant (Programmable Logic Controller‚ 2014). While they are still used extensively‚ relays have some problems. The biggest problem being they are mechanical devices and like all things mechanical they wear out and have to be replaced quite often. In addition‚ relays take

English 101 25 August 2013 The Omnivores Obsession Everybody loves food‚ especially America. Americans are obsessed with food‚ and that is correlated to the fact that in America‚ food is almost always readily available to us. We have fast food restaurants‚ grocery stores‚ restaurants‚ and farmers markets with most of the food being relatively affordable. Our nation without a doubt has many dilemmas that need to be solved‚ however if you were to group all of these dilemmas into different sets and focus

II.Rationale Debate I choose debate as my example. Debate is a method of interactive and representational argument.Debate is commonly carried out .In debating there is a topic to discuss and decide on differences and defining how will they interact. Debate is a type of argument looking for truths‚ and a means of making and evaluating arguments that allows debaters to better understand their own and others positions. This sense of shared ideas toward the truth brings debaters closer together‚ even

Dating back to the day of the Mayans when they were sometimes referred to as “the corn people” (Pollan 19). Pollan takes us back to the “beginning” of the industrial food chain. In The Omnivores Dilemma historical context‚ ideology‚ and setting do not do the reader justice in opening their eyes to the harsh

Logic: the organized body of knowledge‚ or science‚ that evaluates arguments. Principles that we may use as criteria for evaluating the arguments of others and as guides in constructing arguments of our own Argument: a group of statements‚ one or more of which (the premises) are claimed to provide support for‚ or reasons to believe‚ one of the others (the conclusion). Statement: a sentence that is either true/false. Some sentences do not fall onto this category: questions‚ proposals‚ suggestions
Premium Logic Reasoning
thinking involves a knowledge of the science of logic‚ including the skills of logical analysis‚ correct reasoning‚ and understanding statistical methods. Critical thinking‚ however‚ involves more than just an understanding of logical procedures. A good critical thinker must also understand the sources of knowledge‚ the nature of knowledge‚ and the nature of truth. But first‚ what is the science of logic? The object of knowledge involved in the science of logic is "thinking‚" but it is "thinking" approached
