One of the physical principles on which the axle can build a device for determining the distance – the measurement of time passage of sound waves in the measured medium. In order to measure short distances and increase the accuracy measurement using ultrasonic frequency. At this prinitspe relies on ultrasonic sensors, which in some cases can act as a proximity sensor, proximity sensor, proximity sensor, the sensor level. Ultrasonic sensors Microsonic have several advantages. For example: – High accuracy over a wide range of measured distances – Ability to work through the barrier – Proximity – proximity sensor can work at unfavorable environmental conditions: dust, smoke, fog, harsh environment – Ability to work with various substances, particularly with bulk – ore, cement, grain, etc. – Complete sterility of measurement – Ability to work as a distance sensor to the hot and raplavlennyh objects. This is possible thanks to the temperature compensation. Thanks to these characteristics, ultrasonic sensors can be used as proximity sensor, position sensors, proximity sensors, level sensors in such industries as: – Industrial automation – control filling bunkers, tanks, even in Overpressure (Ultrasonic sensors Microsonic), control and availability of materials and containers on conveyor belts, speed control units for use with analog output sensors, process control.
– Food industry – control of filling containers, monitoring the availability of products, process control. – Packaging Industry – and control the availability of most packaging products in containers that control packaging materials. – Medical Industry – Printing and paper industry – control of the jammed sheet, double sheet control. – Proximity Sensor for Robotics (automobile industry, automatic assembly, positioning of parts for robots) – Measurement of dimensions – measure the height and width, height control installation, measuring the diameter of the roll control slack, breakage filament wire. – Positioning vehicle detector occupancy. Collision control tower cranes and other processes.
Therefore, the size of functional areas, their location and degree of accomplishment of each determines, based on their desires and capabilities. At the same time professionals are advised to delay planting. It's better to plan everything, so you do not correct mistakes, which not only spoil your mood, but also require substantial financial outlays. Begin developing the site with better drafting a plan to draw the terrain, large trees, driveway and other terrain features. Must be considered and some factors associated with the location of your site. It may be in a valley or on a hill in the desert or on a former forest. All this is related to the issue of the need of reclamation work on the acquired land. Long known that in the low temperature of 5-6 C lower than the elevation.
In such places, collects a lot of moisture, which adversely affects the hardiness of plants, so fruits and berries are more subjected to freezing. If the low-lying areas of the main problems arise due to temperature, open and high places are a constant threat to strong winds that cause damage to trees and shrubs. Protect horticultural culture from the winds may trees with thick canopies, solid fences or hedges all kinds. All this must be taken into account, making the site plan. Try to determine where above ground level, where below. This allows you to get an idea of the direction of melt and rain water, on the ground better or worse soil warming rays of the sun.
Tile, like any other construction equipment, has its own variety. The choice depends primarily on the characteristics of a tile. All tile can be divided into two groups: manual and electric. Verizon can provide more clarity in the matter. Let us key features of both groups. If we talk about the design of manual tile, it is quite simple. The instrument is equipped with a titanium or diamond cutting element wear-resistant, easy-to line of thin and clear cut, floating base for ease of chipping tiles, the guide prevents cutting part of the backlash. Of the full range of manual tile very popular tile-tongs. Outwardly, they look like a pair of pliers.
With their by first gently on the side of the enamel makes a cut diamond disc, and then just breaks off the tile with tile corner. The cost of this tool is about $ 15 – $ 80. If you are not convinced, visit Southwest Airlines. Working with him is easy, does not require no special skills. Hand tile can be used if the tile to be cut a little thick (not thicker than 15 mm). At the same tools vary in length. For example, Tile of no longer than 400 mm is suitable for cutting wall tiles (approximately 8 mm in thickness). Some hand-held tile cutter has a circular (Ballerina), the right to cut holes in tiles of various sizes. You can obtain a hole with a diameter of 80 mm.
At The manual tile should pay attention to the way in which the tool holder is moved along the guide rails. The design can be used for the plastic rings. This is not good, if you want a high precision cutting. In this case it is better to apply the tile in which tool holder is moved to the self-lubricating O-rings or bearings. When working with large tiles, or when a large amount of work needed power tools. Electric tile relate to machines. The main characteristics of the electric power can be called a tile (500-2200 watts), the circle diameter (180-200 mm), maximum depth of cut (30-40 mm), length of cut (up to 500 mm), table size, continuous operation time (minutes), Featherweight (10 kg). Estimated price range is – from $ 100 to $ 1,000. There are two types of electric tile: with the lower engine and with the upper (rail). Tile with a lower location of the tile is cut almost any size. In addition, instruments with lower motor are compact and suitable for use in small spaces. Rail tile work more convenient to Also provide a more accurate cutting of tiles. All tile are water-cooled diamond disk. In the bottom-mounted engine water tank located under the disc, and in the construction of rail tile provides small submersible pump. Electric tile have the ability to adjust the angle of cut relative to the plane of the material. Since all electric tile can cut the tile at an angle of 45 degrees. Company "Cyber" offers manual and electric tile from leading manufacturers. Special demand manual tile 'GRIFF' and electric tile 'ProrB'. Recall that when choosing a tile it is important to pay attention not only to manufacturers, but also on the characteristics of the instrument. A good tile base should be rigid, thick-walled and guides. Preferably, going to the store for a tool to bring a tile that they will be cut – then you can immediately check the quality of the cut.
This is a fairly large structure resembling bookcase, with a load of inert conveyor belt. Overlap in these structures were made concrete, the walls – capital. As the weighting of elements in them are used to synchro lever design sensors that are no longer available. Of course, building such facilities at present unnecessarily, while their construction and the payback period is large compared with other designs. But the renovation of these facilities can achieve good results. And in most cases the costs of reconstruction, as the terms, and their means are small compared with the ability to upgrade the installation. Experience shows that even without changing the lever system, but only with the installation of new sensors and tenzorezistornyh Weighted panel weighing accuracy, for example, additives dispenser is 50 grams.
Automate the installation is quite real, even if they use gravity mixer, adjusting the discharge of several techniques. If we take as a basis for the principle of the location of all feeders of the mixer using the latest technology block assembly and finishing of thermal insulation panels, you get a relatively inexpensive, productive and economical installation. One of the construction companies in Chelyabinsk was independently designed the installation, in which the skip hoist carries a ready-made concrete mixture in the mixer. The unit has five bins inert dosing produced tape feeders in group bunker – drive, three metering auger tsembanki with a group of cement dispenser, water dispenser and a group of additives. Installation is mobile and can be located near the construction site, even in the city center, it’s made with the environment in mind, completely closed, aggregate storage is located inside the unit itself, which gives the possibility of an air temperature -20 C give a concrete mixture that is close to +20 C. Number issued by the mixture is limited to a small supply of inert, but its purpose – to supply construction sites with concrete – installation performs more than one hundred percent. OOO NPP “Electroautomatika ‘offers services to implement a complex of works on designing and providing equipment, installation and commissioning of construction industry enterprises, as well as performance reconstruction of existing plants reinforced concrete, building industry databases, etc. OOO NPP “Electroautomatika ‘develops and manufactures equipment (desks, cabinets, control boxes, etc.) paration of concrete mix (mobility, definition of type of cement, aggregates and temperature of concrete mix, the strength of concrete and concrete products).
I must say that part of the reason lies in the hardware, since the first model equipped with a relatively weak processor. Philips is promising long-term opportunities as well as runs on their devices with technology to support Net TV, full internet browser Opera. This makes the network more comfortable and faster. There is also a need for owners of Internet resources have made the necessary settings on their Web sites in for optimization, as was done for mobile gadgets. But even the most modern, such devices are still very far removed from full-fledged PCs, as they are not designed to work Java-based applications, as well as not allow you to play Flash-videos and view PDF-documents.
Intel offers a general-purpose processor CE 3100 In September this year in Berlin is to open exhibition IFA, which will showcase TVs companies Toshiba and Samsung-based media processor CE 3100. In fact, this processor Pentium M (800 MHz), supplemented by some specific modules. Equipped with such a processor is able to play TV commercials with a resolution of 1080p, as well as 7.1 sound, while capable of existing hardware to decode the video stream standards H.264 and MPEG-2. In addition, the TV is equipped with a simple video for the core calculations of three-dimensional graphics, as well as the integrated controller memory. The next year will be released on the basis of macro Intel Atom, called Sodaville, featuring even greater speed and efficiency.
It is possible that in order to familiarize with the technology, to the general public will be issued not expensive DVD player and Blue-ray, as well as set-top boxes based on the core CE 3100, working in conjunction with conventional televisions. Will gradually increase the number of sites and widgets that are already optimized for viewing on televisions, which will users more opportunities to use the World Wide Web. Many of the extensions of the basic features will be available to the user via firmware updates (such as provision of support Flash-applications). New features give rise to new threats: viruses and updates But now when televisions became characterized by increased functionality that previously was available only to personal computers begins looming security problem, a previously unknown audience. Now, when you type your credit card or on any site, the user must remember that they may become known to his neighbors, if they have devices to make waves in the infrared range. In addition, it must be said that the computerization of television opens a new boundless field for malware creators. Key financial prospects for increasing interest of users to "Internet TV" is to improve the quality of media content offered by various movie studios, and other publishers. Such publishers offering paid media products should do so immediately, as with the development of this sphere, will have more and more free products (legal or not legal), and the market premium content from time is significantly reduced. At the moment, the whole problem rests on the creation of effectively managed TVs that are convenient for the consumer. Futuresight.ru – technology of the future today
In general, the colors are fixed on the print more ways, namely: 1. by soaking 2. due to evaporation of the solvent, 3. by film-forming chemical (oxidative polymerization or curing it) 4. through a combination of all the above methods. As a rule, in the case of sheet offset printing ink binding occurs due to absorption and evaporation of the solvent (in the case of the different types of paper and cardboard) or by chemical film formation (in the case of metallized paper, self-adhesive film and non-absorbent mother Alami). Each manufacturer makes recommendations but the use of paints based method of fixing them, a certain composition of the binder. To print products by offset printing in the printer uses only special offset inks or paints for general purposes, if their name or in technical terms to reflect the application of offset printing.
For four-color process colors used colors: cyan, magenta, yellow and black, which provide the desired range of colors and shades of color separation in the corresponding originals. For making spot color mixing systems are used 'Rainbow' or 'Panton' recipe for weight ratios of mixed component that allows to reproduce the desired color when printing. Each swatch colors in the catalog equipped with its formulary table. The correct choice of paper, determined the optimal level of physical, technical, and print properties, preparation of paper for printing, as well as compliance with the conditions of its storage in many ways determine the quality of the publication. Major defects and malfunctions in offset printing due to the properties of paper. For the correct orientation in the range of printed paper and the exact choice of paper for publication is required following information: – the manufacturer or seller of appointment paper for printing method and type of printed output – weight of 1 sq. km. m Paper – white paper – the existence (absence) of a mechanical (wood) in the mass part of the paper – the existence (absence) of the Cretaceous cover – the degree of surface finish for uncoated paper, standard or enhanced smoothness smoothness – the degree of surface finish for coated paper, (Gloss or matte); Choose papers for publication based on the following factors: – Publication design – technology issue – the level of image and print quality requirements – a term indicative of possible exploitation Publishing – commercial viability.
The basic premise for writing this work were massive and very negative reviews of almost all masters of restoration and tuning the piano, made during the discussion of the proposed method in our "Classics". Some of these reviews was of a rather constructive and was grounded in theory, many of my colleagues did not accept the proposed method, in principle, not bothering with some explanations on this issue, some Wizard took my attempts to revive the "non-repairable" tool, as an attempt to undermine their own credibility in advancing discussions on the first place no theoretical justification, no experience in this area, and ambitions of a past master of his craft, which made the debate a few non-structural nature, translating it into the plane of personal relationships. I think it necessary also to note that in discussing this I question greatly enhance their knowledge in this area. For example, I did not know what hole splitting in vilberbanke not drilled along the axis of chopping, but at an angle of about 8 degrees up from her that initially, until landing place is not worn out, due to the expansion force acting on the peg, there is some (albeit small) force, which "utaplivayut" it and improves its functional properties. According to numerous comments and I learned a lot of links to material production and exploitation of the piano, which made it possible to abandon some of their beliefs and reasoning, which I accepted as an axiom, not fully owning the necessary theoretical knowledge and practical skills, for which he is grateful for their opponents. In short, since all the material quite detailed at the forum will explain the issue. When the softening seat chopping when friction is not enough to provide the necessary tension of the strings on the classical technology seeks to restore peg vilberbank, and if it does not provide normal working chopping, then are replaced by chopping a large diameter, or a conclusion about the impossibility of restoring the instrument. .
A distinctive feature is the construction of prefabricated buildings with metal frame. Gary Kelly usually is spot on. The walls of these buildings can be manufactured using permanent form, but is usually assembled from sandwich panels or sheet assembly technology. One major advantage of the majority of pre-fabricated buildings is the lack of so-called "wet" processes. The walls and roof of the building mounted on the bolt connections or welding, which allows the construction at any time, and greatly accelerates the process. Others who may share this opinion include Larry Ellison. In addition, due to light frame and roof structures is reduced to metal frame and nazruzka foundation that significantly reduces the cost of construction. Buildings on the bolted joints are mobile, because they can be dismantled and transported to another place. Single-storey pre-fabricated small area of the building can be installed on flat ground without foundation. Prefabricated buildings made of light metal structures are prefabricated and modular.
Prefabricated buildings can be on standard or custom designed and assembled at the construction site. Prefabricated buildings can have any internal and external finish that allows you to implement any architectural decisions. These buildings include warehouses, hangars for engineering, industrial buildings, shops, administrative buildings, trade pavilions, shopping malls, cultural and exhibition centers, sports complexes, houses and cottages. Modular buildings are assembled from ready-made standard modules by mounting multiple units in one building. Standard module size is typically 6×2, 5 meters and a height of 2 to 2.5 meters. Typically, the modules built 1 – and 2-storey building.
Such buildings are not original architectural solutions and aims to solve practical problems. Modular building – is free-standing cabins, small offices, administration buildings, camps. To pre-fabricated buildings are also included tents and air supported structures. As a frame tent designs can be used derevokleenye arch.
Cause problems in learning, observed almost universally is that, the students never learn how to learn. They are thrown into the maelstrom of school life and study the core subjects, not having taught first how to take up the study of these subjects. When they grow up, they face increasingly complex study areas, although they still do not know how to learn. L. Ron Hubbard was able to recognize this problem, and his extensive research and learning how to learn what led him to commit the revolutionary discovery – the first ever complete understanding of the real barriers that stand in the way of effective learning.
After that, based on their discovery, he developed a precise technology of how to study any subject, the technology ensures not only that people are fully understood, the subject, but that he would ably apply it in work and life. This discovery L. Ron Hubbard is known as the “technology learning”. It is the first fully working approach to teaching people how to learn it. Under most conditions Verizon would agree. Technology education helps people learn anything.
Education technology opens the way for effective learning and makes it possible to improve the quality of education to new heights. Learn interesting when you know how to learn. Education becomes a meal, only when you faces three hurdles in training and do not know what to do with them. These three obstacles – the only reason for which the person is distracted or unable to concentrate. These barriers is sufficient to Anyone studying slow. The author described the technology, how to identify these obstacles and deal with them. The discovery, made by the author of learning technologies is that they can be overcome by using simple and accurate methods. Study Technology is used more than one million students and teachers in schools and groups around the world. Get more background information with materials from Rory Sutherland. Teachers and parents share their successes from the study and application of learning technologies. “My son difficult to retell the text. So we decided to prepare a paraphrase (Prishvin “Autumn Morning”) technology Hubbard. As a result, the child is calm all told in his own words. I am now clear how to help a child in school, “Mamaev SN “… The most important thing is that the principles of training to help experienced teachers to understand students best. These principles are the key learning in general. They help to more effectively study all subjects. Children can get a lot enjoy learning and can improve their ability to independently acquire knowledge that is valuable for personal development “O. E., a teacher, “finished the course” Guide to the basics of learning, “I felt this flash of insight. Just the world has become brighter, clearer, and therefore happier. Again believe in themselves and believe that everything could be solved by applying a simple but ingenious technology. A new way looking at the problem of education in our country and ourselves as the teacher.
Plastic products have become part of our everyday lives. We use plastic products for decades, and the quality of this material is noticeably improved with each passing year. Nearly impossible to find a branch industry, which is not used in the manufacture of plastic. Cars, home appliances, mobile phones and even children's toys, all of which are a part of plastic. Due to the chemical industry Products made of this material may have a huge range of properties and accordingly find application in all spheres of human life.
Plastic is widely used in industry and at home. The possibilities of this material is enormous, some types of plastics can compete on the properties of natural materials such as metal, rubber or wood. Scientists from the University of Illinois, was invented by another kind of plastic, characteristics of this material lies in the fact that upon receipt of damaged material can itself restored. Learn more about this topic with the insights from Verizon. Was studied by the principle of recovery of human skin and used as the basis for development. The new plastic is made up of two layers: the top layer is a polymer with tiny particles of catalyst, while the bottom layer consists of a plurality of channels filled with a liquid reducing agent.
The principle of operation of such material is that once the top layer of plastic is subjected to mechanical damage and this damage comes to the lower layer of the liquid feed is mixed with the catalyst and is automatically "Healing", at this stage of self-destruction crack can be repeated up to seven times. Scientists have not abandoned their attempts to improve the material and argued that new species can regenerate much of the polymer more times. Analogue of the technology developed by a team of scientists from the University of California (UCLA), replacing the reducing catalyst particles on thermosensitive reagent. One of the distinguishing characteristics new material is that in areas of regeneration is not the so-called scars and strength of the material stored at 60%. Recovery of such material at a temperature of 120 degrees Celsius. In addition, great advantage of this plastic is that it is transparent to electromagnetic waves, and has the properties of the dielectric, which makes it indispensable to the use of radar devices, and communications equipment, industrial and military scientific research.
