The versatile ISO A Series couplings are used in a wide range of hydraulic applications including construction equipment, manufacturing machinery, and in-plant systems.

They can be found anywhere the fluid transfer lines need to be connected and disconnected for operation or maintenance of equipment.

Rugged construction makes it a good choice for mobile applications including dump trucks, snow plows, refuse hauling, mining, asphalt paving, truck trailer connections and many more. In-plant machinery applications include hydraulic fluid, chemicals and gas lines for paper mills, steel production, and many varieties of plant maintenance and production equipment.

As various manufacturers started to offer quick detachable couplers, most of them entered the market with their own design, which was different 7241–1 their competitors. There was very little interchangeability from one brand to another.

This design is now the most commonly used and is referred to as the standard industrial interchange. However, there are still many different Two Way designs, most of which vary by application. Although there is no organizational standard governing the design of Straight-Thru couplers, a standard industrial design Foster Series FST has developed from usage.

This first tutorial on augmented reality AR will cover the basics of making a personalised digital birthday card. You can download all of the files associated with this tutorial from here. AR is the process of putting digital content images, videos, 3D models, … on top of your surroundings seen through arhoolkit device such as a computer or mobile phone for example.

What it basically does is use a camera as input and augment the stream from it with content not available in real artooliit. As you can see in this image:. I am using Unity 5. More recent versions of Unity 5. Doing the steps from this post on the ARToolkit github might resolve the issue but I did not try it so I cannot assure you it will work. When aryoolkit Unity you will have to create a new unity project.

Creating Augmented Reality Cards with Unity and ARToolkit – Zenva

You can delete the two objects that every new project starts with: To use the ARToolkit package downloaded from the webpage you will have to import the artoolkig to your project: Next go the folder where you downloaded the ARToolkit to and double click on it. In the next window click on import to import the whole package. If everything is imported correctly there should be no errors in the console window.

Once everything is imported the next step is to populate the empty scene. We will need three empty objects and one camera object. If done correctly the Hierarchy window in Unity should look like this:.

After populating the scene in Unity we will start using the imported ARToolkit package. In the inspector window we will have to make some adjustments to the added scripts to get them working.

In this component we will not have to change anything. The last adjustments we will have to make are to the layers of the objects. At this point everything is ready to make an AR app be it for the pc or atoolkit phone. Building the app at this point will look like it is not working. This is the object that will appear on the screen. Artoollit making beautiful intricate objects in Unity is not a part of this tutorial we will add a simple cube or sphere.

Change the scale in X, Y and Z to 0. You can always change the size to whatever you prefer later. Now zoom in to the object. To make sure the object is projected above the marker move the marker in the negative Z direction to about It is always possible to change this to the amount you want, but after some tests I found We are finished and ready to test it!

If we push the play button the object will appear on top of the marker when we put the pattern in front of the camera. The last thing we need to do is make a nice mobile app.

To make an Android app of the project we just created you could just try to build it and choose Android as the Platform. When doing this myself I did not get the camera stream as soon as I started the app.

After some tweaking I found that the settings in the Plugins of the ARToolkit package needed changes from its initial settings. It may work for you with these initial settings, but I had to change them. To change the settings you will have to choose the Plugins folder in the Assets. You will see 6 folders Android, ARWrapper. The Metro folder has two subfolders, Win81 and WindowsPhone Which have multiple subfolders themselves.

In subfolder arm of Win81 click on the ARWrapper file and make sure nothing is selected. The WindowsPhone81 folder has two subfolders, arm and x Make sure that nothing is selected in the ARWrapper file in both folders. It maybe that on windows machines other operating systems appear, I would make sure that x86 is checked for every appearing operating system.

3D Modelling/Examples/AR with Markers

Now make sure only the checkbox for your created scene is selected. Under Platform select Android and click on the Player Settings button. It will open some settings you can change in the inspector window.

The only thing I changed here was the name of the app in the Product Name textbox. This is the name that will appear on your mobile phone, so hrio a nice one. You can add a default icon or change the company name to make the app more personal.

Web based Augmented Reality

Then click the build button and save it wherever you prefer. After the apk file is created copy it to your phone and install it. After installation the first time you run the app, it will ask for permission to use the camera. Of course this is needed for augmented reality so allow it. The only thing left is to make a birthday card.

You can make any card you imagine as long it has the marker somewhere hidden. Do not make the marker too small, otherwise it will not recognize it. Also make sure the black outer border of the marker is visible. Also visible in the video is that it is not very stable if the marker is small. The closer you put the camera to the marker, the more stable the object appears.

Do you have any questions about this article? Do you have any suggestions for a new AR tutorial?

Let me know in the comments section below. Did you do the last part? I had a problem like thatbut making the changes as the instruction says solved it for me. Thank you so much! Finally I could create an app with it.

Fibonacci is best known for introducing Hindu-Arabic numerals to Europe which eventually superseded Roman numerals in everyday life. When Fibonacci libef to prominence, Europe was kiber from the relatively long five-hundred-year period of the Dark Ages. Its cities were beginning to flourish again and trade started to increase rapidly. He was born around AD into the Bonacci family, probably in the town of Pisa in Italy where he grew up. His father, Guilielmo, was a merchant who became a senior customs official.

Guilielmo was given a post in the town of Bugia this would now be part of AlgeriaNorth Africa and Fibonacci soon followed him across the sea. Fibonacci received his education in this area of Africa which was an integral part of the Arab world. This means that he would have learned in Arabic and this must have drawn him into their intellectual world.

Subsequently, he was given the opportunity by his father to travel extensively and explore this interest in greater depth. Fibonacci travelled to Syria, Egypt and then back to Greece. During his travels, which were more akin to a research trip, Fibonacci discovered various mathematical texts that had been translated into Arabic, including the Hindu number system and its decimal approach.

Fibonacci immediately recognised the superiority of this system compared to the Roman numerals with which he had been familiar. He gathered a wealth of mathematical information and brought it back to Italy. Fibonacci explains to the reader how to both write with them and how to perform basic calculations, such as addition, subtraction, multiplication and division.

He shows us how this is done through quadratorm idea of place value. If we have, for instance, the number the first 9 represents hundreds, the next 9 stands for tens and the final 9 represents units.

Therefore, we gain an understanding of the value of a number because of its place in a grouping of numbers. This was a major breakthrough that made basic arithmetic much more practical and straightforward. For example, trade required the conversion of different currencies and the new numerical system imported by Fibonacci was of great practical use for such transactions. Liber abaci also covers algebra and geometry and forms a guide to the known mathematics of the 13 th century.

Until Fibonacci had introduced these Hindu-Arabic numerals, Roman numerals were still the dominant format in Europe. Roman numerals were essentially symbols used to represent the numbers, but they were cumbersome and often time-consuming to apply. Nonetheless, while the convenience and flexibility of the new system were undeniable, Europeans were somewhat reluctant to adopt it.

It was only by the ljber th century that this stubbornness was overcome and the Roman numerals were finally discarded in everyday usage. Fibonacci is probably best known for the so-called Fibonacci Sequence.

We know that Indian mathematicians were aware of this particular sequence as early as the 6 th century. Fibonacci introduced it to Europe as a new form of recursive sequence which was still unknown to the Europeans. A recursive sequence means that the next term of each sequence of numbers is achieved by performing a calculation with the previous term. The sequence first appeared qkadratorum Liber abaci.

In the book, Fibonacci ponders over lber particular example of the sequence applied to the regeneration of rabbits.

Fibonacci wanted quadratorjm know what how many rabbits there would be in 12 months if he placed a pair in an enclosed space. He suggested that if you put a pair of rabbits together to breed, after each month, in ideal circumstances, the rabbits will reproduce.

After each month, Fibonacci noted that quadrxtorum number of pairs of the animals grew according to a particular sequence. The sequence is straightforward but requires clear explanation.

Leonardo Pisano Liber Quadratorum Liber Abaci Pratica Geometriae by Anselm Kiefer on artnet

So we have two rabbits in the first month which is classed as month 0. After the first month, the rabbits have mated but they still have no offspring. However, at the end of the second month, the rabbits give birth to a pair of rabbits.

At the close of the third month, the original pair gives birth again while the new pair mate but have no offspring yet. By the end of the fourth month, the original pair produces another pair quadratourm the other first-born pair has now also produced a new pair.

Tag: Liber quadratorum

At the end of the fifth month, the original pair produces a further pair, the first-born pair gives birth to another pair and the second-born pair also produces a new pair. In theory, this sequence can carry on indefinitely. The golden ratio which has the symbol: However, the Golden Ratio can have a practical application in a number of different areas, ranging from art to architecture. It is seen as providing the ideal proportions for rectangles and triangles. If we examine the ratios of the successive Fibonacci numbers, we find that the bigger pairs of numbers in the sequences get closer to the Golden Ratio figure.

Many scientists have observed the remarkable similarities between the numbers of the Fibonacci sequence and the natural world. For instance, some flowers, such as lilies and irises, have three petals while others, including delphiniums, have eight petals.

There are many flowers with a petal number that does not resemble the sequence, but on average, flower petals do coincide with the Fibonacci numbers. Mathematicians have struggled to offer explanations as to why these extraordinary parallels exist.

There have been some recent attempts to at least understand why flowers generally follow Fibonacci patterns. These revolve around a lbier explanation. For example, the arrangement of leaves around a stem needs to be such that they will be exposed to rain and sun so that growth will be possible. The daisy provides a good example here. The small buds on a daisy begin at the centre of the plant.

When the plant starts to grow, the buds move away from the centre so that they will have sufficient space to grow. Such a functional explanation also applies to the packing of seeds in the seed heads of, say, sunflowers. Sunflower seed heads grow in a specific outward manner and they usually possess 34, 55 or 89 spirals. Again, this reflection qudratorum the Fibonacci sequence may reflect an organisational efficiency in the flower.

This curious resemblance extends to a wide range of plants and objects quaratorum the natural quxdratorum from the number of spirals in pine cones which occur in 8s and auadratorum to fruit and vegetables. The Golden Ratio is also visible in art in the proportions and perspectives of composition and in facial structure.

We cannot prove for sure that mathematics and ideal ratios lay behind certain great works of art. Nonetheless, Leonardo Da Vinci was a mathematician as well as an artist and he studied the platonic solids. So it is likely that he knew the Golden Ratio and may well have applied this to his great works.

For some mathematicians, this tendency to see the beauty and structure of so many things is one step too far, but the coincidences are of great interest. In some cases, the resemblance does have a verifiable connection.

Liber quadratorum

For instance, we know for certain that many musicians and composers have indeed used basic Fibonacci proportions to organise the units of musical time in some of their compositions. Typically, the lengths of musical sections quadgatorum expressed in measures that are often a power of two; four, eight, sixteen and thirty-two. Fibonacci numbers in musical composition offer an alternative approach. These proportions have provided composers, such as Bartok and Debussy, a structure within which to write.

Bartok deliberately composes melodies with interval sizes that allow him to adopt Quuadratorum numbers of semitones. Many of the formal sections of his compositions are carefully divided up in order to correspond to the Golden Ratio.

There is a particular sequence of qadratorum that follows the intervals 34, 21, 13 and 8.

The book includes a substantial collection of theorems some of which had been devised by Fibonacci himself. Fibonacci observes that it is possible to obtain square numbers as sums of odd numbers.

This discovery then allows him to construct Pythagorean triples built around the construction of a right-angled triangle. In this book, Fibonacci also investigated congruent numbers. Numbers are congruent quadfatorum we can divide them by a particular number and get the same remainder. Fibonacci discovered that 7 is congruent, but that 1 is not congruent and came to the important conclusion that no rational right triangle has an area equal to a perfect square.

The Ilber quadratorum marks Fibonacci out as an important contributor to number theory alongside thinkers such as the Greek mathematician Diophantus and Pierre de Fermat a French mathematician working in the seventeenth century. His work made arithmetic accessible in a revolution that was a vital force of transformation of many everyday aspects of life.

His new understanding of number structures also had a huge impact not only on the development of mathematics but on science too. Interestingly, while he is probably best remembered for his famous sequence of numbers, he only dealt with this discovery in brief.

While Fibonacci did not pursue the study of mathematical properties in his sequence, this task quadraforum taken up by others. For example, a French mathematician by the name of Francois Lucas led a substantial body of mathematicians in the nineteenth century who studied the Fibonacci sequence in great detail.

You can find the article on The Register, here: Among lots of emails, almost all of the problems have been issues with faulty goods being sent and refused for returns. Another unhappy customer, Illy, had a similar problem to me many months ago.

A faulty HDD was sent and eBuyer refused to refund the full cost or replace the drive; and demanding it was inboice responsibility of the manufacturer.

You can follow her thread on ConsumerActionGroup. Please do continue to send in your reports. Not only did it manage to take their new site down, it also affected eBuyer and their current sales. The Register have a wonderful report which explains. Ebuyer failed to shore up its web systems ahead of the customer rush and the site was offline for several hours even before the offers officially opened at 11am today. Seems as most of their readers have comments about eBuyer too.

Unfortunately it seems most of the criticisms of eBuyer have been completely removed from the article. The link to this site has also been removed from the article, claiming a lack of evidence.

Fortunately we are now reaching a much wider audience, so hello there! At the time of ordering, he noted there were 23 remaining in stock. He paid, and received confirmation that my order had been allocated stock and was waiting arrival of his shiny and reasonably-priced computer monitor.

eBuyer ‘Invoiced’?

He received an email telling him there was a stock warning on my order. After eventually getting through, he was told that they would be happy to send out a monitor if he paid the full amount! When he asked why the price euyer different they tried to tell him it was a different monitor.

There is some legal basis on when this happens.

If any of our visitors ever come across this with eBuyer or another company, it might be worth contacting the ASA on their Complaints Form.

They now deal with internet advertising.

We really would love to hear from you all about your experiences. This time the product is a camera, and less than 6 months old. Just a reminder, warranty with retailers is always at least one year. So how are eBuyer getting away with this? I would never use this company again. Knvoice opened the box took a couple of snaps, and then put it away. A month or so later she took it out to use it again; on turning it on the LCD screen had failed. They have pushed responsibility back on to me in contravention of the act.

Just to remind you, and eBuyer I suspect Armando Sanchez himself reads this site, given some recent information. Naturally, eBuyer have locked my account after my latest problemtrying to return a HDD which failed after one ebuyeer after purchase. Despite knvoice Sale of Goods Act says returns are the responsibility of the retailer for one year. After logging in, you can get to less of the site than when logged out. The problem I have?

The only way of knowing is you have ingoice a response is by email, and only then can you create a new eNote to reply to it. It could take some time before I get hold of my previous invoices.

What does invoiced mean on ebuyer?

As an aside, I had to do the same thing to O2 recently, since you cannot get full invoices from their site. I phone them up, argued that their invoices online were imcomplete and they happily obliged after some invoce. It might do more for your image than you would expect. I tried explaining that I had this directly connected to my LAN switch with my computer.

This is a fairly typical experience of eBuyer. Apart from them being totally technically incorrect; you should rarely set up a NAT to use forwarded ports, unless you invoicee your data accessible externally to everyone; clearly he wanted to be able to blame the customer as so not have to return the item to the manufacturer.

To me, this seems clearly missold, as is it not fit for dbuyer purpose it was advertised for. Thanks again to Sam for telling her experience. Are you in this situation? Please let us know. Find us at http: Tuesday, December 24th, Uncategorized No Comments.
