in computer science, algorithmic efficiency is a property of an algorithm which relates to the number of computational resources used by the algorithm. an algorithm must be analyzed to determine its resource usage, and the efficiency of an algorithm can be measured based on usage of different resources. algorithmic efficiency can be thought of as analogous to engineering productivity for a .
piezoelectricity is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. the word piezoelectricity means electricity resulting from pressure and latent heat. it is derived from the greek word πιέζειν; piezein, which means to squeeze or press, and ἤλεκτρον ēlektron, which means amber, an ancient source of electric charge. french physicists jacques and pierre curie discovered piezoelectricity in 1880. the piezoelectric .
higher efficiency models can collect particles down to 10 μm. fabric filters are one of the most efficient and cost effective types of dust collectors available and can achieve a collection efficiency of more than 99% for very fine particles.
bisphenol a controversy centers on concerns and debates about the biomedical significance of bisphenol a bpa , which is a precursor to polymers that are used in some consumer products, including some food containers. the concerns began with the hypothesis that bpa is an endocrine disruptor, i.e. it mimics endocrine hormones and thus has the unintended and possibly far-reaching effects on .
baryte, barite or barytes uk: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / citation needed is a mineral consisting of barium sulfate ba s o 4 . baryte is generally white or colorless , and is the main source of the element barium .
bandwidth efficiency. jumbo frames can increase the efficiency of ethernet and network processing in hosts by reducing the protocol overhead, as shown in the following example with tcp over ipv4. the processing overhead of the hosts can potentially decrease by the ratio of the payload sizes approximately six times improvement in this example .
unit processing in chemical process. unit processing is the basic processing in chemical engineering. together with unit operations it forms the main principle of the varied chemical industries. each genre of unit processing follows the same chemical law much as each genre of unit operations follows the same physical law.
common batch processing usage. efficient bulk database updates and automated transaction processing, as contrasted to interactive online transaction processing oltp applications. the extract, transform, load etl step in populating data warehouses is inherently a batch process in most implementations.
although the configural processing hypothesis is a popular explanation for the face inversion effect, there have been some challenges to this theory. in particular, it has been suggested that faces and objects are both recognised using featural processing mechanisms, instead of holistic processing for faces and featural processing for objects.
in an efficient csd architecture, the embedded in-storage processing subsystem has access to the data stored in flash memory array through a low-power and high-speed link. thus, the deployment of such csds in clusters can increase the overall performance and efficiency of big data and high-performance computing hpc applications.
a compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. these semiconductors typically form in periodic table groups 13–15 old groups iii–v , for example of elements from the boron group old group iii, boron, aluminium, gallium, indium and from group 15 old group v, nitrogen, phosphorus, arsenic, antimony, bismuth .
dgcr8 is essential for drosha activity and is capable of binding single-stranded fragments of the pri-mirna that are required for proper processing. human drosha was cloned in 2000 citation needed , when it was identified as a nuclear dsrna ribonuclease involved in the processing of ribosomal rna precursors.
quantum image processing qip is primarily devoted to using quantum computing and quantum information processing to create and work with quantum images. due to some of the astounding properties inherent to quantum computation, notably entanglement and parallelism, it is anticipated that qip technologies will offer capabilities and performances that are, as yet, unrivaled by their traditional .
a superscalar processor usually sustains an execution rate in excess of one instruction per machine cycle. but merely processing multiple instructions concurrently does not make an architecture superscalar, since pipelined, multiprocessor or multi-core architectures also achieve that, but with different methods.
shale oil extraction is an industrial process for unconventional oil production. this process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution. the resultant shale oil is used as fuel oil or upgraded to meet refinery feedstock specifications by adding hydrogen and removing sulfur and nitrogen impurities. shale oil extraction is usually performed above ground by mining the oil shale and then treating it in processing facilities. other modern technol
a padegogical review of efficient coding in visual processing is chapter 3 of the book 'understanding vision: theory, models, and data'. hypotheses for testing the efficient coding hypothesis. if neurons are encoding according to the efficient coding hypothesis then individual neurons must be expressing their full output capacity.
in organic chemistry, the ziegler process also called the ziegler-alfol synthesis is a method for producing fatty alcohols from ethylene using an organoaluminium compound.the reaction produces linear primary alcohols with an even numbered carbon chain. the process uses an aluminum compound to oligomerize ethylene and allow the resulting alkyl group to be oxygenated.
thermionic emission is the liberation of electrons from an electrode by virtue of its temperature releasing of energy supplied by heat . this occurs because the thermal energy given to the carrier overcomes the work function of the material. the charge carriers can be electrons or ions, and in older literature are sometimes referred to as thermions. .
the stem-loop structure is essential for efficient processing of the histone pre-mrna but this structure also controls the transport, translation and stability of histone mrnas. slbp expression is regulated during s-phase of the cell cycle, increasing more than 10-fold during the latter part of g1.
