Machine and Cross Direction Directionality of Paper In paper machine approach flow system, when stock passes through pressure screen, the fibers are oriented lengthwise. If the stock velocity from headbox slice is equal or less than wire speed, fibers which are already oriented lengthwise, will align in the direction of wire run. Fiber alignment can be altered to some extent if stock velocity is less than wire speed. So all papers have a definite grain direction due to greater orientation of fibers in the direction of paper machine run.
I hope this helps.
Some Dogma There is a lot of confusion around touch technologies, and despite a history of over 25 years, until relatively recentlyfew had heard of multi-touch technology, much less used it.
So, given how much impach it is having today, how is it that multi-touch took so long to take hold?
It took 30 years between when the mouse was invented by Engelbart Development force paper research white x English in to when it became ubiquitous, on the release of Windows Yes, a mouse was shipped commercially as early as with a German computer from Telefunken, and more visibly on the Xerox Star and PERQ workstations in Yet, none of this made a huge dent in terms of the overal number deployed.
It took 30 years to hit the tipping point. By that measure, multi-touch technologies, multi-touch got traction 5 years faster than the mouse! One of my primary axioms is: Everything is best for something and worst for something else.
The trick is knowing what is what, for what, when, for whom, where, and most importantly, why. The mouse is great for many things. The challenge with new input is to find devices that work together, simultaneously with the mouse such as in the other handor things that are strong where the mouse is weak, thereby complementing it.
As with the mouse and multi-touch, a whole new ecosystem was required before their full potential could begin to be exploited. Arguably, input techniques and technologies have played second-fiddle relative to displays, in terms of investment and attention.
What I can do is warn you about a few traps that seem to cloud a lot of thinking and discussion around this stuff.
The approach that I will take is to draw some distinctions that I see as meaningful and relevant. These are largely in the form of contrasts: Touch-tablets vs Touch screens: In some ways these are two extremes of a continuum. If, for example, you have paper graphics on your tablet, is that a display albeit more-or-less static or not?
There are similarities, but there are real differences between touch-sensitive display surfaces, vs touch pads or tablets. It is a difference of directness. The nature, or "language" of touch input is highly shaped by the type of actions that are used in interacting with the touch technology.
Abstract.

This chapter describes Transit Oriented Development (TOD), which refers to residential and commercial districts located around a transit station or corridor with high quality service, with good walkability, parking management and other design features that facilitate transit use .
The same touch technology on the same device can assume a very different character, depending on whether the interface depends on discrete vs continuous actions. For example, the most common way of working with touch screens is with direct finger selection of items. For example, one might be asked to "push" the graphical OK button to conclude a transaction on an ATM, or "tap" on the keys of a graphical keyboard in order to enter text in this latter case, multi-touch supports the ability to hold the SHIFT key down while simultaneously tapping one or more alphabetic keys, in order to get upper case.
In contrast, one can also design the interaction such that control is asserted by means of continuous actions, or gestures, such as the lateral stroke gesture that is commonly used in photo-viewing applications to enable the user to go to the next, or previous, image in a sequence, depending on the direction of the stroke.
An example of a multi-touch continuous gesture is the common "pinch" gesture that enables one to zoom in or out of an image or map, for example.Henkel Beauty Care Research & Development is a global team of first class scientists identifying and using new technologies and methods to deliver outstanding products to our customers and consumers.
