Why is my computer running slow? Several factors may cause a computer to run slow. Consider the age of your computer; older computers may struggle to run newer, resource-intensive software.
The common emitter current gain (or β) of a point-contact transistor does not usually exceed 1, [4] whereas β of a BJT is typically between 20 and 200. Negative differential resistance . Point-contact transistors connected in the common emitter amplifier configuration will display negative output resistance, which may be undesirable for ...
Asus Zenbook is a line of notebook computers produced by Asus.The first Zenbooks were released in October 2011 as Ultrabooks, and the original range of products has since been expanded to models ranging from smaller and power efficient notebooks to high-end and larger laptops with additions like discrete graphics processing units.
In January 2008, ASUS began a major restructuring of its operations, splitting into three independent companies: [8] ASUS (focused on applied first-party branded computers and electronics); PEGATRON (focused on OEM manufacturing of motherboards and components); and Unihan Corporation (focused on non-PC manufacturing such as cases and moulding).
The cavity magnetron is a high-power vacuum tube used in early radar systems and subsequently in microwave ovens and in linear particle accelerators. A cavity magnetron generates microwaves using the interaction of a stream of electrons with a magnetic field, while moving past a series of cavity resonators, which are small, open cavities in a ...
Crossed-field amplifier internal operation. A CFA's electric and magnetic fields are perpendicular to each other ("crossed fields"). This is the same type of field interaction used in a magnetron; as a result, the two devices share many characteristics (such as high peak power and efficiency), and they have similar physical appearances.
VSM schematic VSM setup. A vibrating-sample magnetometer (VSM) (also referred to as a Foner magnetometer) is a scientific instrument that measures magnetic properties based on Faraday’s Law of Induction.
High-power 140 GHz gyrotron for plasma heating in the Wendelstein 7-X fusion experiment, Germany.. A gyrotron is a class of high-power linear-beam vacuum tubes that generates millimeter-wave electromagnetic waves by the cyclotron resonance of electrons in a strong magnetic field.
