A Class A bipolar junction transistor amplifier consists of a single transistor, two biasing resistors, a pair of capacitors and a battery or other DC power source. The BJT’s amplifying ability begins only when the input signal exceeds about .65 volts; below that value, the transistor is off. In addition, the transistor works only on positive voltages; it ignores the negative voltage half-cycle of an AC waveform. The biasing resistors turn AC input signals such as audio and radio frequencies into positive voltages; the transistor then amplifies these biased signals with very good fidelity.

AWK is a Linux and Unix shell-processing language you use in the terminal on your computer. AWK is typically used to reformat output from commands you type in the command prompt. The AWK "index" function searches for a reference of the input string and returns the position of the searched string. This function is similar to "indexof" and "position" functions of other languages used to create custom software.
Calculation of polymer relaxation time is important in industries where viscous and elastic materials are used. Both of these materials show signs of strain when stress is applied. Stress relates to the internal forces within the material that cause it to deform over the course of time. Since these materials have the property of viscosity or elasticity or both, they are typically prone to eventual deterioration from their final created form. Calculating the polymer relaxation time provides a more accurate understanding of how long the product will last.

Calculation methods for radio altimeters are overseen by the Federal Aviation Administration.
Horizontal cylinders filled with fluid aboard a boat usually are filled with hydraulic fluid. They generally are the hydraulic cylinders used to control the position of the rudder, the external drive or the outboard motor. Their hydraulic volume varies, depending on the position of the hydraulic piston head in the cylinder. This means the amount of fluid in the cylinder at any given time may be expressed as a percentage of the cylinder's total volume.
Knowing the wall measurement of a tube helps you determine how strong a tube is for your project. Tubes have both an inside (ID) and outside diameter (OD). The difference between these two measurements is the wall thickness. It's difficult to tell how wide a tube's wall is by looking at it -- because a pipe with a large width may have a large inside diameter or a narrow one.
The study of genetic traits in a population across a wide span of time can be done through the study of a population's "haplogroup." Haplogroups are groupings used to delineate specific populations based on one specific genetic trait or characteristic. The expansion time for a haplogroup is the amount of time it takes for a genetic trait to become prevalent or dominant. For instance, a y-haplogroup calculation is a projection of genetic characteristics of a group of people who share the same lineage through a common y-chromosome. Trait calculation can be based on a variety of different models and methods,…
The DB2 database management system, as with most relational databases, employs special files called indexes to speed record lookups. Most of the time, programs use an index to retrieve a specific record from a database table; however, DB2 lets you locate multiple records that represent a range. In the latter case, you create a Structured Query Language statement that uses inequalities such as greater than or less than.
PSGroove is an open source program used to execute the well-known PSJailbreak exploit on PlayStation 3 consoles and enable you to install third-party apps.

The output return loss is a measurement used in the radio field to determine the output and the input of a signal's source. The return loss provides an indication of the strength of the signal. Output return loss has to be measured with the correct input signal also present in order to be accurate. Without the input signal, the measurement will differ significantly. Knowing the output of a signal can be important, because running a signal that exceeds the maximum output level may be dangerous.
A few different problems may cause your Sharp calculator to malfunction or stop working altogether. Fortunately, these issues are apt to be minor, and you can make a quick repair at home with only a small screwdriver and a ballpoint pen. For instance, when the calculator display is dim, the contrast is poor or the readout is blank when you turn on the device, it may be indicative of a dead battery, which is a simple fix. Other minor repairs may be needed to clear bugs in the calculator's programming code or to restore non-responsive keys to working order.
The structural integrity of a floor is its ability to safely support the loads placed on it. With a raised floor system, that means the foundation walls and floor joists must be able to bear the weight of flooring, interior walls and other parts of the house that rest on the floor. Raised floors are built on concrete or block basement walls, concrete or block stem walls or concrete piers. A typical raised floor has a sill plate, a thick board on the foundation, with floor joists between the walls. Joists are a key element in structural integrity.
Baseball is an interesting sport, on so many levels. Fans watch games to see mammoth home runs, overpowering fastballs and acrobatic defensive plays. Many baseball fans keep score during games, which can be a complicated endeavor. From simple box scores to complicated sabermetrics, meaning the statistics of baseball, numbers are a huge part of the game. Keeping track of runs, hits and errors can be tricky for novice baseball fans, but the numbers become easier to add up as you continue following the game.
About 80 percent of new houses today are built with trusses, manufactured in factories using computers and special equipment to make precise cuts and fasten wooden members with strong steel plates called gussets. All trusses are formed in patterns of triangles, and all have some common components: a joist or horizontal chord that goes from wall to wall, two or more angled rafter chords that make the slope of the roof, and internal braces called webs. There are two basic types of attic truss: one is suitable for creating a room, the other simply for adding storage space.
Minecraft is a building game that allows you to create your own three-dimensional world out of textured cubes. It is also one of those games that allows the player to interact with the world that he has created, using the game's survival mode. As with various types of independently produced Java-based games, Minecraft's programming allows the user to sometimes go beyond the regular code to use glitches in the programming to do things other than what the game was intended to do, such as serving as a calculator.
An internal margin is the space between the border of an element, such as a label, cell or text box, and the contents of the element. For a website element, you can change the internal margin using the "padding" property. For elements in graphs, presentations and documents, a menu option is usually available to adjust the internal margin. You can change the internal margin inside spreadsheet cells by altering the text size, changing the column width or changing the row height.
An instrument amplifier’s signal-to-noise figure is a ratio of a standard output signal level to the noise the amplifier produces with no input signal. Audio noise is an unavoidable part of an amplifier’s electronic circuits; an amplifier designer strives to reduce the noise to very low levels. The signal-to-noise, or SNR, ratio is measured in units of decibels, or dB. To calculate SNR decibels, you divide the standard -10dBV signal, which is .316 volts RMS, by the noise voltage of the amplifier, and then take the common logarithm of the result and multiply by 10.
One of the most successful electronic devices of all time, the operational amplifier, also known as the op amp, is a model of simplicity. It provides gain for analog signals through its two inputs – one inverting, one non-inverting. Calculations for an op amp circuit assume an ideal behavior for the device. Though no real-world op amp is perfectly ideal, they are usually close enough for the calculations to work for many practical situations.
Heat that builds up inside your computer can cause performance issues, computer crashes and thermal margin errors. Because a variety of problems can cause performance and stability issues, it can be easy -- at least initially -- to misdiagnose a problem and attribute these issues to other factors. Thermal margin errors, however, point specifically to problems with your central processing unit (CPU). Quick action is essential to finding the cause and preventing permanent damage to your computer.

Lightning-induced currents can be dangerous and detrimental to the soundness of an existing circuit, whether it be electrical, underground coaxial or fiber optic. In particular though, knowing how to calculate the lightning-induced currents in buried cables can help those in particular fields, such as the cable television industry, develop shielding systems designed to impede this flow and minimize damage.
ColdFusion presents programmers with a tag-based language to construct Web pages built with database access and interactivity in mind. However, the ColdFusion language also includes functions and data structures that give it the flexibility of other programming languages. While ColdFusion might not necessarily be the best language to perform extensive calculations with, by following a few basic design rules focusing on code re-usability and modularity, performing large amounts of math is entirely feasible.
California Subject Examinations for Teachers -- often abbreviated to CSET -- are exams used to certify teachers to teach specific subjects. In California, teaching candidates must either complete a teaching-preparation program at an accepted institution or pass an approved exam before being able to teach specific subjects such as science and mathematics. Most CSET exams are based on a combination of multiple choice and constructed-response questions. Interest calculation can show up in a constructed-response question on either the algebra or the calculus section of the CSET math exam. Because calculators are forbidden for these two sections, candidates can still solve…

In audio mixer circuits, a component called an operational amplifier, or op amp, plays a central role. A mixer combines two or more audio signals electronically in varying proportions to produce a musically pleasing result. To accomplish this, the op amp performs several mathematical operations. First, it adds signals together and then it multiplies the result by a common factor to produce signal gain. When designing a mixer, a technician adds the expected values of audio signals and then finds a gain factor that produces clean, undistorted sound.
