Researchers at the University of Barcelona have developed an open-access web app, based on deep learning techniques, which enables the detection and quantification of floating marine litter from aerial photography. Floating marine plastic is a serious threat to the conservation of marine ecosystems. For instance, marine plastics can cause damage to marine animals through ingestion, suffocation, restraint … Read more
A data structure is a way to store and organize data in order to facilitate access and modifications. No single data structure works well for all purposes, and so it is important to know the strengths and limitations of several of them.
The Human Genome Project has made great progress toward the goals of identifying all the 100,000 genes in human DNA, determining the sequences of the 3 billion chemical base pairs that make up human DNA, storing this information in databases, and developing tools for data analysis. Each of these stepsrequires sophisticated algorithms. Although the … Read more
an algorithm is any well-defined computational procedure that takes some value, or set of values, as input and produces some value, or set of values, as output. An algorithm is thus a sequence of computational steps that transform the input into the output. We can also view an algorithm as a tool for solving a … Read more
Cornell University computer scientists have developed a tool which can improve the fairness of online search rankings, without sacrificing relevance or usefulness. For much of the world, Google Search is the entrance to the rest of the internet (other search engines are available). With most users clicking the results towards the top of the first page of returned … Read more
The derivation of the word cryptography is from Greek and means literally secret writing . Modern cryptography is still involved in keeping data secret, but the ability to authenticate a user (and hence apply some kind of access control) is even more important. Although there are many cryptographic techniques and protocols, they mostly fall into … Read more
Algorithm An essential aspect to data structures is algorithms. Data structures are implemented using algorithms. An algorithm is a procedure that you can write as a C function or program, or any other language. An algorithm states explicitly how the data will be manipulated. Algorithm Efficiency Some algorithms are more efficient than others. We would … Read more
An algorithm should have the following characteristics − Unambiguous − Algorithm should be clear and unambiguous. Each of its steps (or phases), and their inputs/outputs should be clear and must lead to only one meaning. Input − An algorithm should have 0 or more well-defined inputs. Output − An algorithm should have 1 or more … Read more
An algorithm is a finite set of instructions or logic, written in order, to accomplish a certain predefined task. Algorithm is not the complete code or program, it is just the core logic(solution) of a problem, which can be expressed either as an informal high level description as pseudocode or using a flowchart. Every Algorithm … Read more
Overview : Insertion Sort Algorithm Sorting is the process of arranging a list of elements in a particular order (Ascending or Descending). What is Insertion sort In insertion sort algorithm, every iteration moves an element from unsorted portion to sorted portion until all the elements are sorted in the list. Insertion Sort Algorithm sorts array by … Read more
