Find MAC Address Identifies Mystery Devices on Your Network

Every network adapter has what is called a Media Access Control address

imply tell the program the range of IP addresses on your network, click a button, and it looks at every address, ferreting out the MAC address for any device using that IP address.

Click the Start menu button on the Windows taskbar.Click 'Run...' on this menu.Type 'cmd' in the text box that appears. A command prompt window launches on the desktop.In this command window, type 'ipconfig /all'. Details are shown for each of the computer's network adapters. Computers installed with VPN software or emulation software will possess one or more virtual adapters.The 'IP Address' field states the current IP address for that network adapter.The 'Physical Address' field states the MAC address for that adapter.

La sphère de Bloch, du nom du physicien et mathématicien Félix Bloch, est une représentation géométrique d'un état pur d'un système quantique à deux niveaux ; c'est donc, entre autres, une représentation d'un qubit. Il est possible de généraliser la construction de cette sphère un à un système à n niveaux.

Henry David Thoreau

Lorsque les Puritains arrivèrent en Amérique du Nord, c’est tout naturellement que, profondément imprégnés de langage biblique, ils assimilèrent leur entreprise à la traversée du désert des Israélites, à une errand into the wilderness qui faisait d’eux des envoyés ou messagers dans la nature sauvage, symbole de la mise à l’épreuve qui devait permettre de recouvrer la pureté de la foi. La nature était ainsi fermement encadrée dans un paradigme providentialiste qui suffisait à lui donner sens. Dans cette perspective, elle apparaissait comme un lieu sauvage que l’homme avait pour mission de domestiquer et de rendre productif, par un processus de réforme ou d’amélioration (improvement) qui ferait de ces "solitudes hurlantes" (howling wilderness) la terre promise qu’était appelé à être le Nouveau Monde.

Japan collab transmits record data speeds on terahertz waves

Researchers from Japan-based semiconductor manufacturer Rohm, together with a team from Osaka University, have come up with a chip that, in experiments, has achieved a wireless data transmission speed of 1.5 gigabits per second. This is a record breaker as the world's first terahertz wireless communication achieved with a small semiconductor device. The chip’s ability to transmit at such a quick speed is not the end of the story. Even higher transmission speeds of up to 30 Gbps may be possible in the future, according to reports.

“Research into terahertz technology utilising Terahertz frequency (100GHz-10THz) is now receiving increasing attention around the world,” according to an Osaka University publication

A particle carrying a charge of 1 coulomb and passing through a magnetic field of 1 tesla at a speed of 1 meter per second perpendicular to said field experiences a force of 1 newton, according to the Lorentz force law. As an SI derived unit, the tesla can also be expressed as (in SI base units).[3] Units used: A = ampere C = coulomb kg = kilogram m = meter N = newton s = second T = tesla V = volt Wb = weber [edit] Electric vs Magnetic Field

The difference between magnetic field strength (in tesla) vs electric field strength can be confusing.[citation needed] The difference is that a force of magnetic field on a charged particle is generally due to the charged particle's movement[4] while the force imparted by an electric field on a charged particle is not due to the charged particle's movement. This can be seen by looking at the units for each. Electric field is N/C, while magnetic field (in tesla) can be written as N/(C*m/s). The difference between the two is m/s, or velocity. This can further be seen by noting that whether a field is magnetic or electric is dependent on one's relativistic reference frame (that is: one's velocity relative to the field).[5][6] In ferromagnets the movement creating the magnetic field is the electron spin[7] (and to a lesser extent electron orbital angular momentum). In current carrying wire (electromagnets) the movement is due to electrons moving through the wire (whether the wire's straight or circular).

paper that's stronger than steel

University of Technology, Sydney scientists have reported remarkable results in developing a composite material based on graphite that is a thin as paper and ten times stronger than steel.

Graphene paper (GP) is a material that can be processed, reshaped and reformed from its original raw material state - graphite.

The copter itself is organised around the main CPU. The job of this CPU is to acquire the physical measurement given by the gyroscopes and accelerometers and to control the motors to keep the copter stable. This is done by a regulation loop which controls the motors speed 250 times per second. The radio communication has a pretty low bandwidth and is used to send commands to the copter and receive telemetry data from it. The CPU program can be updated by radio.

The computer runs control and telemetry programs. The control program reads the input from a game-pad and sends control commands to the copter. We also have programs that can configure the copter regulation parameters and log the measurements in order to make easier to tune the regulation. All the development is done on Windows and Linux. Indeed we are 3 to work on this project, two of us work on Linux and one is mainly on Windows. Using FLOSS permit to handle that in a very effective way. We are mainly using the GCC compiler from CodeSourcery for the copter program compilation, GNU Make for the project build, Mercurial for the source control, and python/pyusb for the communication with the copter. All these softwares works seamlessly on both Linux and Windows and made the project pretty easy to handle. The distance between the motors (horizontally and vertically) is around 8 cm and the total weight is around 20 g.

Unlicensed Mobile Access ou UMA est une technique qui a pour objectif de remplacer la couche physique des réseaux GSM et GPRS par des bandes de fréquences libres d'utilisation, celles des 2,4 GHz, ou l'on trouve Bluetooth et Wi-Fi entre autres. Elle a été développée par un consortium d'entreprises nommé UMAC comptant entre autres Alcatel, Cingular, Ericsson, Motorola, Nokia, Nortel, Siemens, T-Mobile et Kineto Wireless. L'objectif ultime de l'UMA est de faire converger les protocoles de communications des téléphones mobiles, fixe et informatiques.
