what is process deviation?
409524
A process is generally designed to run based on a set of parameters (temperature, pressure, flow rate, etc.).\n\nA process deviation is a variation of the process from the designed parameters.\n\nNote:  The process deviation could be accidental or intentional (such as a test run to determine effect on the process).

Would seem to mean that there is an error somewhere that needs attention.  Maybe a change to your system has been detected and needs your attention!

Don’t confuse Accuracy, Resolution with Sensitivity. \n\nAccuracy \n\nAccuracy describes the amount of uncertainty that exists in a measurement with respect to the relevant absolute standard. It can be defined in several different ways and is dependent on the specification philosophy of the supplier as well as product design.\n\nResolution \n\nIn relative amounts, resolution describes the degree to which a change can be detected. It is expressed as a fraction of an amount to which you can easily relate. For example, printer manufacturers often describe resolution as dots per inch, which is easier to relate to than dots per page.\n\nSensitivity \n\nSensitivity is an absolute quantity; resolution is a relative quantity. Sensitivity describes the smallest absolute amount of change that can be detected by a measurement, often expressed in terms of millivolts, microhms, or tenths of a degree.\nSensitivity should not be confused with accuracy—they are entirely different parameters. For example, a device specified with 1-mV sensitivity may only be accurate to 10 mV with an applied input of 10 V. Yet if the 10-V input signal changed by 1 mV, the device still could observe the difference. Sensitivity sometimes can be improved by averaging. \n\nhttp://www.evaluationengineering.com/archive/articles/1298pct.htm\n\nAccuracy is usually determined at 4 points 25%, 50%, 75% and 100% of full scale. This is accomplished by:\n \n1.Placing the dial indicator in a stand.\n2.Place the stand on a clean surface plate.\n3.Select a gage block of any size.\n4.Preload the indicator a few divisions (insure the lever is horizontal to the plate).\n5.Spin the dial until the DI reads zero. \n6.Place another gage block (or wrung gage blocks) under the lever that’s 25% of full scale. DI should read desired value +/-1 div..\n7. Repeat at 50%, 75% and 100% of full scale.\n\nSensitivity is the smallest value that an instrument can measure. What makes this confusing on a dial indicator is it is generally also +/-1 division but the method to measure it is different. \n\nAfter step 6 perform the following:\n\n8.Remove the 25% gage block.\n9.Select a gage block 1 division from the 25% block. (Normally 0.001”) \n10.Place the block under the DI and verify it reads +/-1 div.\n11.Repeat at 50%, 75% and 100% of full scale.\n\nWe use a lot of GIDEP calibration procedures. They’re military manuals available to the public because well; we paid for them with our tax money. It’s worth it’s weight in gold.\n\nhttp://www.gidep.org/\n\nWhat is GIDEP?\n\nGIDEP (Government-Industry Data Exchange Program) is a cooperative activity between government and industry participants seeking to reduce or eliminate expenditures of resources by sharing technical information essential during research, design, development, production and operational phases of the life cycle of systems, facilities and equipment.

Not quite sure if you mean the 'process' of an individual program on a personal computer or the method by which software processes are controlled by an operating system. In any case I've answered both.\n\nFirst of all the definition of process "a series of actions or steps taken in order to achieve a particular end".\n\nIn terms of a software process this can mean anything from the program that collects your email from a POP3 server somewhere to one that controls the images on your monitor.\n\nTaking the email collection program as an example this program would follow a process something like this:\n\n- Contact POP3 server\n- Negotiate login (handshake, swap ID, etc)\n- Check for new email\n- Download new email\n\nNow to the control of software processes on an operating system. \n\nInitiating the above program on a UNIX system for example would start a 'software process'. This process is assigned an identification number called a PID or process ID. Also at this stage the process is assigned system resources, memory/disk space and is queued for processor time (roughly speaking).\n\nFor example (running in background):\n\n$ xosview &\n[1] 11670\n\nUsing the 'ps' command to view running processes:\n\n$ ps\n  PID TTY           TIME  CMD\n  736 tty1      00:00:00  bash\n  743 tty1      00:00:00  startx\n  744 tty1      00:00:00  tee\n  752 tty1      00:00:00  xinit\n  756 tty1      00:00:00  kwm\n  ...\n11670 pts/4     00:00:00  xosview\n11671 pts/4     00:00:00  ps\n\nOf course on a windows system starting a program is much simpler, for instance double-clicking on a program icon. Yet it essentially does the same thing; initiate a software process and assign it a process ID and resources.

Well, if 'dodgy' just means poor quality, it can't make your computer quite as fast as the same quantity of high-quality ram would. If you mean nonworking, though...\n\nBlue screening, primarily right in the middle of a program. Also can cause 'insufficient memory' messages, even when you don't have many resource-consuming programs running. Not to mention overall slow preformance.

In data and signal analysis, an apparent trend or signal caused by random events or noise is often called spurious.

In telecommunication, the term frequency deviation has the following meanings:\n\nThe amount by which a frequency differs from a prescribed value, such as the amount an oscillator frequency drifts from its nominal frequency.\n\nIn frequency modulation, the absolute difference between the maximum permissible instantaneous frequency of the modulated wave or the minimum permissible instantaneous frequency of the modulated wave and the carrier frequency. Usually written Δf.\n\nIn frequency modulation, the maximum absolute difference, during a specified period, between the instantaneous frequency of the modulated wave and the carrier frequency.

Tracking error is the standard deviation of the portfolio of differences:\nLet X be your portfolio; let B be the chosen benchmark.\nThen d=X-B is the portfolio of differences (which adds to zero)\nthen TE=std(d) is the tracking error. If you have a covariance matrix S for your assets, then \nTE=((X-B)'S(X-B))^(1/2).\n\nTracking error "interpretation" is the uncertainty of the excess returns (that is, of the return of the portfolio vs the benchmark's)

usually a process is the route by which something is converted in something else. process of digestion or cell replication. \n unless you mean the scientific process(like in papers and projects) which is where scientist write out exactly what they did in the experiment.

Six-sigma is a quality control program that strives for less than 3.4 defects in a million opportunities; or near perfection.  In statistics, sigma represents areas under a bell curve (similar to IQ normal curves).  If all defects fall outside the shaded area (outside three sigma on either side, where the center is perfect and all shaded areas are acceptable) there is very little shaded area (defects) left.

A statistic used as a measure of the dispersion or variation in a distribution. It is equal to the square root of the arithmetic mean of the squares of the deviations from the arithmetic mean. Simply put, standard deviation measures how spread out the values in a data set are. More precisely, it is a measure of the average difference between the values of the data in the set. If the data points are all similar, then the standard deviation will be low (closer to zero). If the data points are highly variable, then the standard variation is high (further from zero). the greater the standard deviation, the higher the risk. it is always positive, and NEVER negative. the formula you use is....well i can't write it because i don't have the symbols on my keyboard, but i'll try:\n\n\nσ= √(Σ[D-E]^2P)\n\nwhere:\nσ=sigma=standard deviation\nΣ=capital sigma= the sum of\nD=outcome\nE=expected value\n^2= squared\nP= Probability\n√=square root\n\nhere is an example:\n\n(Assumptions)(Outcome probability)(Outcomes)\n(Pessimistic)(0.2)                     (300)\n(Successful)(0.6)                     (600)\n(Optimistic)(0.2)                     (900)\n\n(sorry, the table won't keep the spaces, so i put brackets in)\n\nok, you need the expected value, which is the sum of all of the outcomes, times their probabilities, like so:\nexpected value = 300×0.2+600×0.6+900×0.2 = 600\n\n\nthen standard deviation would be calculated like so:\nstandard deviation = {(300-600)2×0.2+(600-600)2×0.6+(900-600)2×0.2}½ = 190\n\nhope that helped! oh, and if you don't understand, the "to the power of 1/2" part is the same as taking the square root.

Six Sigma is a term usually related to manufacturing or process engineering that seeks to reduce variability in the product or process. \n\nThe Six Sigma process is taught to people within the managerial structure at a company. A person who goes through the course earns what is called a "green belt." A person who goes through further training and shows the ability to implement and teach Six Sigma methodology earns a "black belt."

One cool way that I have seen it derived is based on Jayne's Formalism.\n\nAssume we sample process, and measure the mean and standard devation of the samples. There are many possible distributions that will produce those exact mean and standard deviation. \n\nJayne's Formalism chooses the distribution which maximizes the entropy of the distribuiton. This is viewed mathematically as the distribution that makes the minimum number of assumptions regarding the distribution.\n\nI always thought that was kinda cool.

thats not good it should eventually drop to 1, 2 or 0 if there is no applications running, but only end a process if you recognize the name and its something your running, otherwise windows might have a damaging error in fact you should only end applications, not processes because ending all applications will end all the unimportant processes
