Molecubes are a collection of modular robots created by Hod Lipson and Victor Zykov from Cornell University. A molecube is made of two rotatable halves, one with the microprocessor which represents the intelligence behind the unit, and the other with a motor for rotating the joint. A group of the cubes can be connected into a variety of shapes.

A robot constructed entirely of molecubes would be able to repair itself using extra cubes, and to create a copy of itself using the same number of cubes. [1] Physical self-reproduction of both a three- and a four-module robot was demonstrated. [2] [3] Subsequent open-source development, with support from Microsoft Research and Festo [4] reduced size and weight of the molecubes. [5] Additional molecube types were produced including: hinges, grippers, batteries, wheels, cameras and more. [6]

Xpress Transport Protocol (XTP) is a transport layer protocol for high-speed networks promoted by the XTP Forum developed to replace TCP. XTP provides protocol options for error control, flow control, and rate control. Instead of separate protocols for each type of communication, XTP controls packet exchange patterns to produce different models, e.g. reliable datagrams, transactions, unreliable streams, and reliable multicast connections.

Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces." Since then, it has been used both in pre-rendered and realtime scenes in many console and PC games.

Its structure and responsibilities differ between provinces and territories.

Modular self-reconfiguring robotic systems or self-reconfigurable modular robots are autonomous kinematic machines with variable morphology. Beyond conventional actuation, sensing and control typically found in fixed-morphology robots, self-reconfiguring robots are also able to deliberately change their own shape by rearranging the connectivity of their parts, in order to adapt to new circumstances, perform new tasks, or recover from damage.

The Micromechanical Flying Insect (MFI) is a miniature UAV composed of a metal body, two wings, and a control system. Launched in 1998, it is currently being researched at University of California, Berkeley. The MFI is among a group of UAVs that vary in size and function. The MFI is proving to be a practical approach for specific situations. The US Office of Naval Research and Defense Advanced Research Project Agency are funding the project. The Pentagon hopes to use the robots as covert "flies on the wall" in military operations. Other prospective uses include space exploration and search and rescue.

Hydraulic roughness is the measure of the amount of frictional resistance water experiences when passing over land and channel features. One roughness coefficient is Manning's n-value. Manning’s n is used extensively around the world to predict the degree of roughness in channels. Flow velocity is strongly dependent on the resistance to flow. An increase in this n value will cause a decrease in the velocity of water flowing across a surface.

Menemerus bivittatus is a spider in the family Salticidae commonly known as the gray wall jumper. It is a pantropical species and is usually found on the walls of buildings or on tree trunks where it stalks its prey.

The Accra Declaration confirmed the support of the two main healthcare interoperability standards by the open source community. With the support of major open source advocates, this allowed free and unfettered access to the core healthcare interoperability standards which resulted in a substantial increase in their usage. The International Healthcare Modelling Standards Development Organisation (IHMSDO) had earlier placed the intellectual property (IP) of the HL7 and DICOM standards and the IHE profiles into the public domain under the creative commons licence.

Xulvi-Brunet and Sokolov's algorithm generates networks with chosen degree correlations. This method is based on link rewiring, in which the desired degree is governed by parameter ρ. By varying this single parameter it is possible to generate networks from random to perfectly assortative or disassortative. This algorithm allows to keep network's degree distribution unchanged when changing the value of ρ.

Engineering biology is the set of methods for designing, building, and testing engineered biological systems which have been used to manipulate information, construct materials, process chemicals, produce energy, provide food, and help maintain or enhance human health and environment.
