bio inspired computing examples

In particular, a level 0 machine would be built that simply avoided contact with objects. Knowing what kind of deeper understanding is possible potentially leads to at least three additional roles for biology: Biology as source of principles. The intrusion detection system implements a costimulatory mechanism as the requirement of a human confirmation of behavior flagged as potentially anomalous—that is, it presents matches signaled by an activated detector to a human operator for confirmation. Aside from the technical challenges of achieving the desired results of synthetic biology projects, there are significant concerns about the misuse or unintended consequences of even successful work. A bio-inspired version with analog data processing is a distant aim. Consider the following quote from M.J. Frechet, a chemistry professor at the. However, gear assemblies are inherently imprecise, because their very motion requires some degree of play where the gears meet (i.e., some nonzero compliance). View our suggested citation for this chapter. The remarkable growth of both computer science and biology in recent decades has drawn attention to their areas of intersection. Title H. Asada and T. Kanade, “Design of a Direct-Drive Mechanical Arm,” ASME Journal of Vibration, Stress, and Reliability in Design 105(3):312-316, 1983. Keep only those paths that begin with a specified starting and ending node. Hainfeld, N.C. Seeman, K. Musier-Forsyth, and R.A. Kiehl, “Assembly of Nanoparticle Arrays by DNA Scaffolding,” Journal of Nanoparticle Research 4:313-317, 2002. As noted in Chapter 1, even when biology cannot provide insight into potential computing solutions, the drive to solve biological problems can still inspire interesting, relevant, and intellectually challenging research in computing—so biology can serve as a useful and challenging problem domain for computing.3, For example, IBM used the problem of protein folding to motivate the development of the BlueGene/L supercomputer. Such a strategy might well be useful for an artificial machine processing a large visual field. This video explains the basic idea of nature inspired computing. Then, the reporter strand is ligated, extracted, and amplified to read out the answer.143. Keep only those paths that enter all of the nodes of the graph at least once. The PSO algorithm is biologically inspired in the sense that it is a plausible account of bird flocking behavior. The use of DNA as a computational system had been discussed theoretically by T. Head in 1987,104 but the idea leapt into prominence with Len Adleman’s publication in 1994 of a working experiment (Box 8.3) that solved a seven-node instance of the Hamiltonian path problem, an NP-complete problem that is a special case of the Traveling Salesman Problem.105. Entirely apart from the increased ease of prediction, the introduction of series elasticity enables a local response to any sudden changes in loading—during which time the motors involved can build up torque to handle that load. This costimulatory signal is generated independently and reduces the incidence of pathogen detectors that are overly sensitive (and hence the likelihood of autoimmune reactions). Sensors could monitor the immediate environment for light, sound, temperature, magnetic or electric fields, acceleration, pressure, humidity, selected chemicals, and other kinds of information, and the motes, when interrogated, would send the data over kilometer-scale ranges to a central base station, as well as communicate with local neighbors. If its task were to evolve a program for financial analysis, such functions might be included in the set of primitives from which an evolutionary process might draw. This algorithm is also well suited for implementation in a simple robot. (Memory detectors have lifetimes that range from days to the lifetime of an organism, and the underlying mechanisms governing their lifetimes are not well understood.). These structures might be useful to end users in and of themselves, or might serve as nanofabrication machinery that could construct other structures useful to the end user. Just as data can be represented as lists of numbers or in graphical form, computer programs (which embed algorithms) can be represented as “source code” that is readable by human beings or as “object code”—the raw ones and zeros of binary computation. This is especially a concern for organisms, such as those intended to detect or treat pollutants, that are designed to work in the open environment. But these functions operate at too low a level to build the kind of hierarchical structures needed to do anything complicated. (An agent might be a single firm in an economy, a single driver on a crowded freeway, and so on.) Imagine a family of primitive molecular-electronic components, such as conductors, diodes, and switches, is available from generic parts suppliers. Principles of amorphous computing may enable a more top-down specification of systems that more closely tracks how humans define the functionality they wish to obtain from software. Smith, “DNA Computing on Surfaces,” Nature 403:175-179, 2000. Each particle evaluates the function as it flies through phase space and keeps trying to turn back toward the best value that it has found so far. The list of desirable functions in a biological system is long, and successfully mimicking biology for one particular function requires the ability to separate nonrelevant parts of the system that do not contribute to the desired function. Engineering—particularly, electronics design—is an appropriate discipline to draw on, because no other design field has experience with constructing systems composed of millions or even billions of components. Dynamic, in the sense that pathogen detectors are continually being produced to replace those that are (routinely) destroyed. Word design is currently an active area of DNA computation research. The human immune system has evolved to its present state due to many evolutionary accidents as well as the constraints imposed by biology and chemistry—much of which is likely to be artifactual and mostly irrelevant to the underlying principles that the system embodies and also to the design of a computer security system. Nature builds systems out of the same atoms that are available to human engineers. These techniques have not, as a rule, been derived from the consideration of biological systems. M. Dorigo, “Optimization, Learning, and Natural Algorithms,” Ph.D. Dissertation, Politecnico di Milano, Italy, 1992; M. Dorigo, V. Maniezzo, and A. Colorni, “The Ant System: An Autocatalytic Optimizing Process,” Technical Report No. By careful design of the base sequence of these pads, tiles can be designed to connect only with specific other tiles that complement their base sequence. This is “healing” only in the loosest sense, although it certainly is a valid fault tolerance technique. - Concepts such as emergence, self-organisation and embodiment. These two models are direct ancestors of the particle swarm optimization (PSO) algorithm, first published in 1995.14 The algorithm substitutes a mathematical function for the original roosts and cornfields, and employs a conceptual swarm of bird-like particles that swoop down on the function’s maximum value, even when the function has many local maxima that might confound more standard optimization algorithms. The result, by definition, is a program that is still syntactically correct, still runs, but does not necessarily do what is desirable. To reduce processing load, the brain uses a strategy we know as “attention” that focuses on certain parts of the available information and discards other parts. The same comments apply to the source code of a program. Once the tiling structure completes assembly, that strand can then be isolated and sequenced by PCR or another technique to determine the ordering of the tiles. Because evolutionary solutions are cumulative, in the sense that they build on previous solutions, the design process does not have an opportunity to develop solutions that are clean and elegantly designed from first principles. However, this programming model is unlikely to catch on for complex tasks without significant higher-level abstractions available. An average cell neighborhood of 15 is sufficient to reliably self-assemble complex shapes and geometric patterns on randomly distributed cells. Second, the Watson-Crick complementarity of the bases (A with T, G with C) allows matching operations, conceptually similar to “if” clauses in programming. These ants likewise seem to have an instinct for keeping the brood chambers well organized; if workers are presented with a random jumble of ants-to-be, they will quickly see to it that the eggs and micropupae are in the center, while the larger and more developed pupae and larvae are toward the outside where they have more room. University of Memphis, Equal Opportunity and Brown, Jr., “Experiments in Balance with a 2D One-legged Hopping Machine,” ASME Journal of Dynamic Systems, Measurement, and Control 106:75-81, 1984. Of particular interest to synthetic biologists are modifications to cellular machinery that simulate the operations of classical electronic logic gates, such as AND, NOT, XOR, and so forth. Similarly, the krill-herd algorithm ( Gandomi & Alavi, 2012) … These BioBricks contain DNA sequences at either end that are recognized by specific restriction enzymes (i.e., enzymes that will cut DNA at a target sequence); thus, by adding the appropriate enzymes, a selected DNA section can be spliced. The computer is said to have passed the Turing test if the outside observer is unable to distinguish between the two.).
