Processing element outputs

Artificial Neural Networks. An Artificial Neural Network (ANN) consists of a network of nodes (processing elements) connected via adjustable weights [Zurada, 1992]. The weights can be adjusted so that a network learns a mapping represented by a set of example input/output pairs. An ANN can in theory reproduce any continuous function 95 —>31 °, where n and m are numbers of input and output nodes. In NDT neural networks are usually used as classifiers... [Pg.98]

Artificial neural networks (ANN) are computing tools made up of simple, interconnected processing elements called neurons. The neurons are arranged in layers. The feed-forward network consists of an input layer, one or more hidden layers, and an output layer. ANNs are known to be well suited for assimilating knowledge about complex processes if they are properly subjected to input-output patterns about the process. [Pg.36]

The plant will process 27,836 TPSD of Illinois No. 6 high sulfur bituminous coal containing 4.45 wt% sulfur on an as recieved basis. The output of fuel products form the plant is 15,531 BPSD of naphtha and 51,325 BPSD of syncrude. 1,178 tons per day of elemental sulfur is produced. This represents 95 wt% of the total input sulfur in the feedstock coal. Most of the remaining sulfur is still present in the liquid synthetic crude oil. From the available data for this proposed plant, the output of elemental sulfur is calculated to be 0.0176 tons per product barrel. Since a high sulfur coal was used this represents a high sulfur production case as it is likely that direct liquefaction facilities will use high sulfur Eastern bituminous coals as feedstock. [Pg.93]

Braunl et al. 1995). The task of each processing element is to estimate the illuminant L for its image pixel. This estimate is then used to compute the output according to... [Pg.201]

Given the maximum deviation between local space average color and the pixel intensity, the output pixels are calculated as follows. First, local space average color is subtracted from the current intensity. Then, the deviation dj is used to rescale the difference. Henceforth, we drop the coordinate of the current processing element. [Pg.252]

As an additional test, we ran all algorithms on input images that were similar to the stimuli used in Helson s experiments. This is particularly important as some of the algorithms operate on a grid of processing elements and the output may not be uniform over the entire sample. Also, some simplifying assumptions had to be made in the theoretical analysis. We will see in a moment that the calculated output colors correspond to the colors that were theoretically computed. [Pg.316]

A CCN consists of a number of relatively simple, densely interconnected, processing elements (bone cells), with many more interconnections than cells. Operationally these cells are organized into layers an initial input, a final output and one or more intermediate or hidden layers. However such networks need not be numerically complex to be operationally complex [109]. [Pg.24]

A neural network consists of many processing elements joined together. A typical network consists of a sequence of layers with full or random connections between successive layers. A minimum of two layers is required the input buffer where data is presented and the output layer where the results are held. However, most networks also include intermediate layers called hidden layers. An example of such an ANN network is one used for the indirect determination of the Reid vapor pressure (RVP) and the distillate boiling point (BP) on the basis of 9 operating variables and the past history of their relationships to the variables of interest (Figure 2.56). [Pg.207]

The processing elements are typically arranged in layers one of the most commonly used arrangements is known as a back propagation, feed forward network as shown in Figure 7.8. In this network there is a layer of neurons for the input, one unit for each physicochemical descriptor. These neurons do no processing, but simply act as distributors of their inputs (the values of the variables for each compound) to the neurons in the next layer, the hidden layer. The input layer also includes a bias neuron that has a constant output of 1 and serves as a scaling device to ensure... [Pg.175]

The Motor Output subsystem consists of those structures which we physically affect the external world and our own bodies. In terms of conscious awareness, these structures are primarily the skeletal, voluntary musculature. If I take a minute out from writing to pet my cat, I am using my Motor Output subsystem with full awareness. The Motor Output subsystem elements that primarily affect our own bodies are glandular secretions and other internal, biological processes. These latter, involuntary effectors are controllable not directly, but through intermediates. I cannot directly increase the amount of adrenaline in my bloodstream, for example, but if I make myself angry and wave my fists and shout and holler, I will almost certainly increase the amount of adrenaline secreted. [Pg.78]

For example, a dynamic task net resembles a running development process with all tasks, resources, and all documents which are created during the process. Elements of dynamic task nets are task, input parameter, output pareimeter, control or feedback flow, data flow, etc. [Pg.623]

Hidden neurons communicate only with other neurons. They are part of the large internal pattern that determines a solution to the problem. The information that is passed from one processing element to another is continued within a set of weights. Some of the interconnections are strengthened and some are weakened, so that a neural network will output a more corrected answer. The activation of a neuron is defined as the sum of the weighted input signals to that neuron ... [Pg.331]

Process elements which are describable by Eq. (3) are often called first order time lags or first order RC stages, since they cause the output signal to lag behind the input signal and since the time constant in each case is the product of a resistance term and a capacitance term. For... [Pg.44]

Finally, our analysis will be focused on inputs and outputs of elements at the ecosystem level and on their controls. In the short term, nutrients can limit NPP or other processes when organisms demands for an element exceed the supply of that element for N and P, that generally means that potential uptake exceeds mineralization. A particular element may be limiting because it cycles more slowly than another for example, biochemical mineraliza-... [Pg.218]

Noise is associated with each component of an instrument — that is, with ihesource, the inpuitransducer, all signal-processing elements, and the output transducer. Furthermore, the noise from each of these elements may be of several types and may arise from several sources. Thus, the nolselhal is finally observed is a complex composite that usually cannot be fully characterized. Certain kinds of instrumental noise are recognizable (1) thermal, or Johnson, noise (2) shot noise (3) flicker, or I//, noise and (4) environmental noise. A consideration of the properties of the four kinds of noise is useful. [Pg.111]

Most of the world s production of iodine comes from the saltpeter deposits in Chile and natural brines in Japan. In Chile, calcium iodate is found in caliche deposits extracted from open pit mines in the Atacama Desert. Applying an alkaline solution to the caliche yields sodium iodate and iodine is obtained from the sodium iodate by reduction with sulfur dioxide. In Japan, iodine is a by-product of the production of natural gas, which is extracted from brine deposits a mile or two below ground. Iodine is recovered from the brines by one of the following two methods. In the blowout process elemental iodine is liberated as a result of the reaction of chlorine with sodium iodide in the brines. Elemental iodine is blown out of the brine with air and then purified in subsequent reaction steps. The second method, ion exchange, involves recovery of dissolved iodine from oxidized brines using anion-exchange resins packed in columns. In 2010, Chile produced 18 000 metric tons of iodine, compared to Japan s output of 9800 metric tons. Chile has reserves of 9 million metric tons, some 60% of the world s total reserves of iodine [10],... [Pg.2]

If more than one process element is necessary to manufacture a product, the sequential arrangement is denoted as a process chain. Individual process elements are arranged in either sequential, parallel, or hybrid type. Therefore, the process chain can be defined as a controlled sequence of process elements with the objective of transforming certain items from an input state into a conformable output state. In terms of manufacturing engineering, transformation items are raw and semifinished parts, in general it could be other material and immaterial objects such as energy, information, or services as well. [Pg.976]

Considerable heat is generated during the chain reaction, primarily as a result of the fission process. When the system is operated for an extended period of time at a high production output of element 94, the large ammmt of heat thus generated must be removed in order to stabilize the chain reaction. [Pg.706]

A neural network is a system of interconnected processing elements called neurones or nodes. Each node has a number of inputs and one output, which is a function of the inputs. There are three types of neurone layers input, hidden, and output layers. Two layers communicate via a weight connection network. The nodes are connected together in complex systems, enabling comprehensive processing capabilities. The archetype neural network is of course the human brain, but there is no further resemblance between the brain and the mathematical algorithms of neural networks used today. [Pg.397]
