Pros and cons of using electronic

Spreads the assessment load for staff and students Digital platforms allow the delivery of assessments to be scheduled. TEA also makes it easier to repurpose and reuse your resources learning objects and can enable automatic marking, thus further reducing your workload. Assessments delivered via digital platforms can be scheduled and automatically released at set intervals, thus enabling the assessment load and its associated marking and feedback provision to be spread throughout the term, which can reduce the sense of assessment overload for you and your students. Using technology can increase assessment efficiency by, for example, allowing the creation of reusable resources learning objects and by facilitating automatic marking.

Pros and cons of using electronic

Since the initial Adleman experiments, advances have been made and various Turing machines have been proven to be constructible. Incomputer scientist Mitsunori Ogihara working with biologist Animesh Ray suggested one to be the evaluation of Boolean circuits and described an implementation.

Pros and cons of using electronic

Because of this, the DNA is very suited as a medium for data processing. The theoretical maximum data transfer speed would also be enormous due to the massive parallelism of the calculations.

This allows the system to take a similar amount of time for a complex calculation as for a simple one. This is achieved by the fact that millions or billions of molecules interact with each other simultaneously.

However, it is much harder to analyze the answers given by a DNA-Computer than by a digital one.

The Pros and Cons of Super Duper Cheap Home Phone Plans

He managed to solve for example an instance of the directed Hamiltonian path problem. For this purpose, different DNA-fragments were created, each one of them representing a city that had to be visited.

Every one of these fragments is capable of a linkage with the other fragments created. These DNA-fragments were produced and mixed in a test tube. Within seconds, the small fragments form bigger ones, representing the different travel routes.

The Pros and Cons of Electric Cars

Through a chemical reaction that lasts a few daysthe DNA-fragments representing the longer routes were eliminated. The remains are the solution to the problem. However, current technical limitations prevent evaluation of the results.

Solving a Hamiltonian path in a graph with 7 summits. Tic-tac-toe game[ edit ] InJ. Stojanovic created a DNA computer able to play tic-tac-toe against a human player.

Each bin contains a substrate and various combinations of DNA enzymes. The substrate itself is composed of a DNA strand onto which was grafted a fluorescent chemical group at one end, and the other end, a repressor group.

Fluorescence is only active if the molecules of the substrate are halved. The DNA enzyme simulate logical functions.

By default, the computer is supposed to play first in the central square. The human player has then as a starter eight different types of DNA strands assigned to each of eight boxes that may be played.

To indicate that box nr. These strands bind to certain DNA enzymes present in the bins, resulting in one of these two bins in the deformation of the DNA enzymes which binds to the substrate and cuts it. The corresponding bin becomes fluorescent, indicating which box is being played by the DNA computer.

The various DNA enzymes are divided into various bins in such a way to ensure the victory of the DNA computer against the human player. Neural network based computing[ edit ] Kevin Cherry and Lulu Qian at Caltech developed a DNA-based artificial neural network that can recognize bit hand-written digits.

Pros and cons of using electronic

They achieve this by programming on computer in advance with appropriate set of weights represented by varying concentrations weight molecules which will later be added to the test tube that holds the input DNA strands. Furthermore, particular mathematical computations have been demonstrated to work on a DNA computer.

As an example, DNA molecules have been utilized to tackle the assignment problem. Aran Nayebi [23] has provided a general implementation of Strassen's matrix multiplication algorithm on a DNA computer, although there are problems with scaling.

In addition, Caltech researchers have created a circuit made from unique DNA strands, which is able to calculate the square root of numbers up to In the fractional coding two DNA molecules are used to represent each variable.DNA computing is a branch of computing which uses DNA, biochemistry, and molecular biology hardware, instead of the traditional silicon-based computer benjaminpohle.comch and development in this area concerns theory, experiments, and applications of DNA computing.

The term "molectronics" has sometimes been used, but this term had already been used for an earlier technology, a then.

Smart electric meters are electronic devices that track and record the use of electricity in customers' homes.

Big Picture Posts

Electric utility companies have been replacing the outdated analog meters (that are read manually each month) with the new, high-tech digital smart meter versions.

These smart meters automatically capture information about electricity consumption and then transmit it back to the. Let’s consider some of the pros and cons of the digital age as it reflects in the developing hands and minds of today's young people.
