Once again he reached behind his seat, this time pulling out a child's red polka-dot umbrella, no doubt another garage sale bargain.
When at last they arrived at the trail's end, Westlake parked, placed a rock behind his wheel, and held out his polka-dot umbrella.
Hence for sending both a dot and a dash, reverse currents of short duration are sent through the line, but the interval between the reversal is three times as great for the dash as for the dot.
In this manner it was possible to hear a Morse code dash or dot in the telephone.
A simple fraction with ioo for denominator, can be expressed by writing the two figures of the numerator (or, if there is only one figure, this figure preceded by o) with a dot or " point " before them; thus 76 means 76%, or 17 -6 6 o.
Ebi-nor) which dot its surface it descends to 820 ft.
While still an undergraduate he formed a league with John Herschel and Charles Babbage, to conduct the famous struggle of "d-ism versus dot-age," which ended in the introduction into Cambridge of the continental notation in the infinitesimal calculus to the exclusion of the fluxional notation of Sir Isaac Newton.
Thus for a dot, first a negative and then a positive current is sent to the line, the effect of the current continuing during the time required for the paper to travel the space between two holes.
For the dot the armature is deflected by the first current, the ink-wheel being brought into contact with the paper and after a short interval pulled back by the reverse current.
The interpretation of the signals is according to the Morse code, - the dot and dash being represented by deflexions of the line of dots to one side or other of the centre line of the paper.
The instrument consists of two cams, the form of which regulates the components of the curbed signal, one cam being for the dot element and the other for the dash element, which by their sequence give the letter signals; these cams, by means of clutches controlled by the relay, are mechanically rotated by clockwork, the speed of rotation being approximately adjusted to the rate of transmission of a single element, so that the requisite number of consecutive elements is transmitted corresponding to the duration of contact of the relay arm with the side controlling that particular element.
Very briefly stated, his method consists in sending out a group of wave trains at certain irregular but assigned intervals of time to constitute the simplest signal equivalent to a dot in the Morse code, and a sequence of such trains, say three following one another, to constitute the dash on the Morse code.
Until the advent of the nomads from central Asia, and the devastation of Mesopotamia and the opposite Syrian shore of the river, there were many flourishing cities along its course, the ruins of which, representing all periods, still dot its banks.
This plain produces large quantities of indigo and opium, and is physically remarkable for the number of isolated conical hills which dot its surface.
These trading settlements, which dot the coast for a distance of r000 m., are about sixty in number.
- If, in the identity 1 (1 +anx = 1+aiox+aoly+a20x 2 +allxy+a02y 2 +..., we multiply each side by (I -ï¿½-P.x+vy), the right-hand side becomes 1 +(aio+1.1 ') x +(a ol+ v) y +...+(a p4+/ 1a P-1,4+ va Pr4-1) xPyq - - ...; hence any rational integral function of the coefficients an, say f (al °, aol, ...) =f exp(ï¿½dlo+vdol)f d a P-1,4, dot = dapg The rule over exp will serve to denote that i udio+ vdo h is to be raised to the various powers symbolically as in Taylor's theorem.
When it is remembered that the punching tool was guided solely by the hand and eye, and that three or more blows of the mallet had to be struck for every dot, some conception may be formed of the patience and accuracy needed to produce these tiny protuberances in perfectly straight lines, at exactly equal intervals and of absolutely uniform size.
It broadened and deepened many of the valleys; rounded the hills; turned aside many streams, causing changes in drainage and giving rise to innumerable waterfalls and rapids; and it formed the thousands of lakes, large and small, which dot the surface.
Thickets and small acacias dot the steppes, which, green during the kharif or rainy season, at other times present a dull brown burnt-up aspect.
A few scattered palms dot the western shores, and a palm grove is to be found near Kefr Harib on the south-east.
Of the numerous islands that dot the Gulf many are partly at least of volcanic origin, notably Qishm and Ormuz.
It is rather due to an overpowering sense of the value of organization - a sense that liberty can never be dissevered from order, that a vital interconnexion between all the parts of the body politic is the source of all good, so that while he can find nothing but brute weight in an organized public, he can compare the royal person in his ideal form of constitutional monarchy to the dot upon the letter i.
In Oscan, which had an o-sound, but no symbol for it, a new sign was invented by placing a dot between the legs of the symbol for u - V.
This, however, is found only in the best-written documents, and on some materials the dot cannot be distinguished.
Several thousand lakes of clear water, formed by glacial action, dot the surface of the state, and many of them are lined with picturesque woodland shores.
They are often found on the flat-topped hills which dot the Karroo.
The ant-bear, with very long snout, tongue and ears, is found on the Karroo, where it makes inroads on the ant-heaps which dot the plain.
The mean sea-level is shown by the horizontal line aa, dotted where it passes through the land, and the natural mean level of saturation bb, above the sea-level, by a curved dot and dash line.
The vertical distance above the line ab of any point in the dotted line dc is proportional to the vertical component of the compressive stress on the line ale assumed to vary uniformly from face to face, and similarly the vertical distance of any point in the3-dot-and-dash line ae above the line ab is proportional to the vertical component of the stress determined experimentally.
A few palmyras, date-palms and screw-pines (a sort of aloe, whose leaves are armed with formidable triple rows of hook-shaped thorns) dot the expanse or run in straight lines between the fields.
In the case of numbers the X may be replaced by a dot; thus 4.3 means 4 times 3.
The Aramaic. and Hebrew v, which seem so different, arise from a circle left open at the top, 0, a form which can be traced in Aramaic from the 5th or 6th century B.C. In the Greek alphabets the circle appears sometimes with a dot in the centre, but in many cases it is doubtful whether this mark is, intentional, or is only the result of fixing a sharp point there while describing the circle.
High, fill the lakes and dot the quieter reaches of the river beds.
Along the coast a string of summer bathing resorts is springing up similar to those that dot the south-east coast of the Crimea.
In districts like that of Cripple Creek their enormous ore "dumps" dot the mountain flanks like scores of vast ant-hills; and in Eagle River canyon their mouths, like dormer windows into the granite mountain roof, may be seen 2000 ft.
The whole of this operation represents a dot and a dash or the letter " a."
