An automaton $\mathcal A = (X, Q, \delta, q_0)$ is called permutation-free iff no word $w \in X^*$ induces a nontrivial permutation of a subset of the states of $\mathcal A$. Also let $\eta \in X^*$ be a second infinite word with the property that the first $k$ symbols of $\eta$ and $\xi$ coincide (so that $\eta$ visits at least the states from $\mathcal R$) and that all infixes up to a length of $k$ are the same. Furthermore, if $\mathcal A$ is not permutation-free than there exists a word $w$ and $n > 1$ states $\{ s_1, s_2, \ldots, s_n \}$ with $\delta(s_1, w) = s_2, \delta(s_2, w) = s_3, \ldots, \delta(s_n, w) = s_1$. 7Regular languages and the pumping lemma13Is there a natural family of languages whose generating functions are holonomic (i.e. You can use the simulation method suggested by Marshall and Spiegelhalter to compute confidence intervals for the rankings.
Marshall and Spiegelhalter advocate replacing the population means with the sample means, and the population standard deviations by the sample standard errors. For these data, the ranking of the first three airlines (AQ, HA, WN) seems fairly certain, but there is more uncertainty for the rankings of airlines that are in the middle of the pack.
Finally, I did not find a function var() for a matrix needed to calculate the standard error of the mean for each airline's arrival times.

The equivalent electrical circuit model for an inductive-loop system allows the loop’s inductance and quality factor to be calculated.
Appendix A describes the derivation and application of an equivalent circuit model and computer program that calculates the apparent self-inductance and quality factor versus frequency of square, rectangular, quadrupole, and circular loops of round wire buried in a roadway. Inductive-loop detectors are commonly used in actuated and computer–controlled traffic surveillance systems. The frequency range of typical electronics units is 20–60 kHz, although newer units that provide vehicle classification can operate at hundreds of kilohertz. The equivalent loop system model contains a roadway inductive-loop model, a transformer model, and a transmission line model. The stray capacitance between turns of wire in an inductive loop is calculated using a multilayer transformer model.
The capacitance between loop turns is calculated using a low-frequency, multilayer, transformer model.(4) The model assumes uniform flux coupling through the loop turns with minimum leakage flux. Figure A-3 shows the circuit model for a multiturn loop, where LL represents the low-frequency inductance of the loop and CLi the lumped internal capacitance across the loop terminals.
When the voltage drop is linear, the voltage across each turn is directly proportional to the total voltage drop and inversely proportional to the number of turns. External capacitance is created when a conductor is located in the vicinity of a dielectric material. Galejs determines the impedance of a buried insulated wire.(8) The capacitance is calculated assuming the region surrounding the slot or cavity is finitely conducting.
Stratton also shows that a perfectly conducting outer conductor, as found in a coaxial line, provides a good approximation to a finitely conducting one when calculating shunt admittance.(10) The slot walls are approximated by infinitely conducting ground planes, as illustrated in Figure A-5. The series loop resistance RL is composed of the direct-current wire resistance R, the high-frequency skin-effect resistance Rac, and the ground resistance Rg. The external inductance of a single-turn rectangular loop is given by the sum of the inductance of two pairs of conductors.
The mutual inductance is positive when the current flow in the filaments is in the same direction and negative when the current flow is in opposite directions.
Equation A-36 can be used to calculate the total mutual inductance of the coaxial and parallel rectangular loops displayed in Figure A-8. Figure A-9 illustrates a two-turn quadrupole loop(20) and Figure A-10 a multiturn quadrupole loop. In order to calculate the mutual inductance between the offset loops in the quadrupole loop model, a general formula for the mutual inductance of parallel, offset filaments is required.
This expression assumes that the filament lengths are much less than the wavelength divided by 2p and the conductor radius is much less than the filament length.
Figure A-12 illustrates an inductive-loop system electrical circuit model that contains resistive, capacitive, and inductive components.
The frequency shift ΔfD at the terminals of the electronics unit is required to compute the sensitivity of the inductive-loop system as a function of loop and cable inductance.
Equation A-62 shows that the cable inductance LC strongly affects the sensitivity of the frequency shift electronics unit.
The definitions of the parameters that appear in Figure A-14 are referred to the primary of the transformer.
The equivalent transformer model of Figure A-15 was used to derive an expression for the transformed load impedance ZinT.


The loop-detector analysis system (LDAS) computer program calculates loop inductance and quality factor for rectangular, quadrupole, and circular loops.
Tables A-3 through A-5 list calculated loop inductance and quality factor as a function of conductor size. Loop inductance should be measured at 1 kHz to remove effects of capacitance when determining the number of turns in a buried loop.
I’ve created this grid about one year ago to do one small thing which is converting supplied XML file into a grid view, with hard coded styles names inside.
Currently I’m using it in about 8 pages (some of them have 4 grids) and till now everything went well. And after spending fairly good time in testing, I would like to share it with you hoping that you’ll find it useful. I was thinking to post it as a code snippet, but I changed my mind; because Tutorials let you have a general view about the code and the ability to edit it as required.
In order to load the XML, we will use an AJAX code snippet (attached) to load the XML document to the client, and since AJAX is not the subject matter here, I’ll just mention how to use that snippet.
1- bindFrom(): uses AJAX to communicate with a server side script that generates the XML on fly (or load already created XML file).
2- refresh(): removes the grid if it’s already exists, call createGrid() function and then append the new created one. This function must be called after assigning values to all necessary properties (styles, events…).
Note: don’t use POST method (even if you have nothing to post in the data argument) if you’re loading a pre-created XML file which is physically exists on the host.
This function uses AJAX function I mentioned before, so first we check if this function is available, and notify user if not. Add commas to the left and right of hiddenCols string to facilitate detecting column’s name in order to hide it. Assign a new Array with one empty string element to the rows styles arrays if it’s not set properly. Assign all xmlObj’s nodes those already stored in the dataSource property to the xml variable. Assign the first row nodes to xmlfields variable to be used to generate the column’s headers if not specified. Check if tempheader (the instance of headers property) is declared, if so, use the tempheader to create the grid header, if not create the headers base on the node’s names of xmlfields. Create the headers cross cell TH and append it to the TR just if both of row’s headers and column’s headers are set to be displayed. If checkContent function is defined, we pass the cell’s data with the current row, column indexes, the column’s name and the TD object itself to that function and assign its return to data again.
Add onmouseover event to the TD in order to get the column’s index which is the same as the cell’s index within its parent row. Add the row number to the column’s header cell (since it’s pivot table, the row’s header will become the column’s header.
If displayRowsHeaders is set to true, create TH element, add the header text to it, add the row header style if declared.
We Get the cell data and pass it to the checkContent() function if declared and pass it the current row, column indexes , the column’s name and the TD object itself. Call onBindComplete() function if declared and pass the table object to it so you might want to do something with it before it appears on the page.
So, if there are hidden columns we always deduct them from the actual rows count to get the viewable rows count. 9- selectedRow returns the selected row element TR, you can use the (cells) collection to get the data from a specific cell inside selected row. In order to deal with the grid object outside the function where it was created; make sure you assign it to a variable that can be accessed from where you want to use it. 13- Accessing the table’s elements from outside script which is not related to an event, usually we’ll use the element’s (id), and as you already know we didn’t add this attribute to our table, but if you noticed that we keep a reference to the table assigned to the (gridRef) property.
Here is the gist of my approach so far, with some dummy data, I would love a pointer in where to go next. If you play with the results of the function that generates a table of matrix indexes that you can apply the significance to. Also remember that the hardcoded 4's in the line above are the length of your (square) grid.

Is there a case (besides light speed in any given medium) where speed is experimentally measured rather than theoretically calculated? More formally for any $R \subseteq Q$ and any $w \in X^*$, $\delta(R, w) = R$ implies $\delta(r, w) = r$ for all $r \in R$. Let $\xi \in X^{\mathbb N}$ an infinite word, and let $R \subseteq Q$ be the set of words visited by $\xi$ in $\mathcal A$. Meaning $\delta(s_1, w^n) = s_1$, so in an permutation-free automaton $\delta(q, w^n) = q$ always implies $\delta(q, w) = q$, meaing that if $w^n$ has a loop, then already $w$ has a loop.
These can keep track of much more info than prefixes and infixes of fixed sizes so most likely your conjecture is false. The following statements compute the mean delays and standard errors for each airline in 2007.

The effects of transmission lines and matching transformers between the loop in the roadway and roadside electronics units are included in the model. The size, shape, and number of turns of wire in the loop should be designed to provide adequate vehicle detection sensitivity and prevent the lead-in wire and lead-in cable from reducing sensitivity. When a vehicle is sensed by the loop, a small decrease in loop inductance is detected by the electronics unit. Loop capacitance can cause the inductance sensed by the electronics unit to change significantly with frequency if too many turns are used in the roadway loop. A similar method was used by Palermo.(6) The actual loop turns are connected as shown in figure A-2.
This does not occur when a conductor is placed near another conducting surface such as a metal. These observations allow the combination of a coaxial conductor and TEM transmission line for use in modeling the capacitance of loop wires embedded in a slot.
The dominant resistance is the ground resistance, which is caused by currents induced in the conductive pavement and subgrade material. Grover(22) shows that this type of general formula can also be derived by applying the laws of summation of mutual inductance to Equation A-36. The unit of conductance is the mho (for inverse ohms) and is denoted by an inverted capital omega.
If the cable inductance is one-tenth or less of the loop inductance, the cable has a negligible effect on inductive-loop system sensitivity, provided the quality factor QD is five or greater. The loop inductance and quality factor are transformed by the transmission line (nonshielded, twisted-loop wire) to the roadside junction box and transmission line (shielded, twisted pair) between the junction box and electronics unit in the controller box. This is helpful when we want to call bineFrom() multiple times, otherwise the new call to bindFrom() will add a new grid under the last created one. This is useful when you want to do some modification to the grid or calling another thing after the grid has been completely created but not yet included into the page.
The graphs would be ggplot2 (line or bar) graphs plotting the two columns (variables) that correlate. I assume this is where I need some sort of loop to generate multiple plots where varA and varB are correlated. Also let $k$ be such that the first $k$ symbols considered as a finite word visit all states from $\mathcal R$ and choose $k$ so that it is minimal.
The first row contains the lower end of the 95% confidence limits for the ranks; the second row contains the upper limit. It discusses statistical and computational algorithms, statistical graphics, simulation, efficiency, and data analysis.
The capacitance between the loop conductors and surrounding pavement material is shown to have a major effect on the magnitude of the loop’s apparent self-inductance. The inductance value at the input to the electronics unit must be within the range specified by the unit’s manufacturer. Furthermore, since the series inductance of the transmission line decreases the magnitude of the inductance change at the input to the electronics unit, the loop inductance should be larger than the transmission line series inductance.
To better predict inductive-loop system performance, an equivalent circuit model of the loop system was developed and programmed on a computer.
The frequency shift electronics unit sensitivity results also apply to period shift electronics units.
The program also models a transformer between the loop and transmission line or between the two types of transmission lines. Measured loop inductance and quality factor data versus frequency were unavailable for quadrupole and circular loops. The addition of a transmission line of 240-ft (73.2-m) length approximately halves the quality factor.
The computer program described in this appendix allows engineers to calculate the apparent loop inductance and quality factor versus operating frequency (20–60 kHz) for selected loop size, shape, wire diameter, number of turns, turn spacing, slot width, pavement loss tangent, and slot sealant dielectric constant.
The loop inductance can be increased by winding additional turns into the loop and adding a transformer between the loop and transmission line.
The computer program allows inductiveloop system designers and maintenance technicians to calculate the detection system inductance and quality factor as a function of frequency, wire gauge size, wire spacing, etc. Ground resistance is calculated by assuming that the pavement and subgrade materials cause a magnetic loss similar to that of a ferrite or iron core in an inductor.
Inductive-loop detector applications requiring transmission lines over 200 ft (61 m) in length should use number #12 AWG wire for the loop and nonshielded transmission line.
