Samsung Galaxy Note 9The Samsung Galaxy Note 9 (stylized as Samsung Galaxy Note9) is an Android-based phablet designed, developed, produced and marketed by Samsung Electronics as part of the Samsung Galaxy Note series. It was unveiled on 9 August 2018, as the successor to the Samsung Galaxy Note 8. It is available in six colours (Ocean Blue, Midnight Black, Lavender Purple, Metallic Copper, Cloud Silver, and Alpine White). Many Galaxy Note 9 features were leaked before the official launch, including its S-Pen.
Zoom (software)Zoom, stylized as zoom or Zoom Meetings, is a proprietary videotelephony software program developed by Zoom Video Communications. The free plan allows up to 100 concurrent participants, with a 40-minute time restriction. Users have the option to upgrade by subscribing to a paid plan. The highest plan supports up to 1,000 concurrent participants for meetings lasting up to 30 hours. A beta version of Zoom that could host conferences with only up to 15 video participants was launched on August 21, 2012.
Scattering parametersScattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by electrical signals. The parameters are useful for several branches of electrical engineering, including electronics, communication systems design, and especially for microwave engineering. The S-parameters are members of a family of similar parameters, other examples being: Y-parameters, Z-parameters, H-parameters, T-parameters or ABCD-parameters.
Nikon(ˈnɪkɒn, ˈnaɪkɒn; ɲiꜜkoɴ), also known just as Nikon, is a Japanese multinational corporation headquartered in Tokyo, Japan; it specializes in creating and marketing optics and imaging products. The companies held by Nikon form the Nikon Group. Nikon's products include cameras, camera lenses, binoculars, microscopes, ophthalmic lenses, measurement instruments, rifle scopes, spotting scopes, and the steppers used in the photolithography steps of semiconductor fabrication, of which it is the world's second largest manufacturer.
SystemA system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, surrounded and influenced by its environment, is described by its boundaries, structure and purpose and is expressed in its functioning. Systems are the subjects of study of systems theory and other systems sciences. Systems have several common properties and characteristics, including structure, function(s), behavior and interconnectivity.
Physical chemistryPhysical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids).
Mesh analysisMesh analysis (or the mesh current method) is a method that is used to solve planar circuits for the currents (and indirectly the voltages) at any place in the electrical circuit. Planar circuits are circuits that can be drawn on a plane surface with no wires crossing each other. A more general technique, called loop analysis (with the corresponding network variables called loop currents) can be applied to any circuit, planar or not.
Q factorIn physics and engineering, the quality factor or Q factor is a dimensionless parameter that describes how underdamped an oscillator or resonator is. It is defined as the ratio of the initial energy stored in the resonator to the energy lost in one radian of the cycle of oscillation. Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidth when subject to an oscillating driving force. These two definitions give numerically similar, but not identical, results.
Mazda, also known as simply Mazda, is a Japanese multinational automotive manufacturer headquartered in Fuchū, Hiroshima, Japan. The company was founded on January 30, 1920 as Toyo Cork Kogyo Co., Ltd., a cork-making factory, by Jujiro Matsuda. It changed its name to Toyo Kogyo Co., Ltd. in 1927 and started producing vehicles in 1931. The name Mazda was derived from Ahura Mazda, the god of harmony, intelligence and wisdom in Zoroastrianism, as well as from the surname of the founder.
