Laser beam machining as an abbreviation (SBM) is a filing method that results from the action of the focused laser beam on the material to be machined. In this process by transferring the photonic energy to the surface of the piece.thermal energy is generated by this heat at the site of laser radiation. the material is separated from the piece in the form of molten or vapor.< < > laser beam machining (SBM) is an unusual production of machining. A type of machining in yen laser is directed to the workpiece for machining. In this framework, thermal energy is used to remove materials from metal or non-metallic surfaces. The high frequency of monochromatic light falls on the surface of the Earth, and then heating - melting and vaporization of the material occurs due to collisions with photons. Laser beam machining is suitable for fragile materials with low conductivity ، but can be used in most materials.< < > the laser focusing system mechanism is similar to the laser welding system mechanism. Laser machining is divided into three main categories-one-dimensional laser machining-two-dimensional laser machining and three-dimensional laser machining.< < > one-dimensional laser machining is actually the same as laser drilling which is done only along the laser beam.machining. Two-dimensional machining includes laser cutting، laser grooving and laser marking, which laser cutting is the most widely used in this sector. In this method, it is possible to create a two-dimensional shape by cutting flat and flat parts in small thicknesses.< < > three-dimensional machining involves laser sharpening، laser milling and laser engraving, which in this method usually use two focused beams and cut out parts.< < > the laser machining process is very different from traditional machining. In traditional machining the basis of filings is based on the creation of mechanical stresses on the part wins on the parts but in laser machining, the basis of filings is based on the concentration of thermal energy on the workpiece....

Spot (SPOT) is a French commercial earth observation satellite that produces high-resolution satellite images. The name is an acronym for the French name which is a literal translation of the Earth observation satellite. The satellite was launched by Spot Image in Toulouse, France and orbited by the French Space Agency in the 1970s. < < > the SPOT satellite is designed to improve knowledge of Earth management by exploring Earth's resources detecting and predicting Climatological and oceanographic phenomena and monitoring human activity and natural phenomena. < < > the SPOT satellite system includes a set of satellites and ground control centers to plan and manage satellites to produce and disseminate satellite images.

satellite initial spot with the use of the rocket, the Ariane 2, 3 and 4 belong to the European Space Agency's space were, while the satellites spot 6 and 7 with the use of the rocket PSLV organization Space Research India in circuit groups....

Today, vessels FPSO an integral part of the offshore industry and the development of many offshore oil and gas fields are not cost effective without the use of these advanced vessels. In fact, as FPSO stands for the first letters of the phrase, Floating Production Storage and Offloading, which is the direction of ease of expression, not just of the title FPSO is used. This floating four multi-purpose, etc. as its name implies some kind of ship special is that in order to be processed compounds, hydrocarbon, etc., storage and also transfer it to the oil tankers cache goes to work. The ship is designed to be able to refine and store the hydrocarbons produced from underground equipment and platforms that are withdrawn nearby.

vessels, FPSO, because of the ease in doing the process three times, in the offshore preference for that time, because by using it, no need to build infrastructure such as podium, etc. and pipelines for the operation of The that store do not have much time. would not be, and the same agent causes operation of the squares of the distances very far from the drought have been found for oil companies affordable. Of course, the dimensions of this vessel are so large that all the equipment for the production and storage of oil and transfer easily accommodates both the deck and under the hull of these vessels، a variety of facilities are located. To imagine the magnitude of a vessel in your mind, you just need to know that three giant 747 boosters are easily placed on the deck of this vessel.< < >another point is these vessels use an advanced anchoring system to stabilize their positions on the sea waves, which is carried out in several stages with the help of several anchoring systems. Anchors are placed in the middle of the ship so that the vessel can easily rotate around the axis and easily stabilize its position at sea by changing currents below or in stormy conditions.. Another remarkable thing about the vessels is that these vessels can connect to several oil wells at a time at a depth of and collect hydrocarbons (oil and gas) through mobile pipes and transport them to tanks on the surface of the ship. It is interesting to note that the refining facilities on the deck are exactly the same as the refining facilities on the coastal. This facility includes separation and injection equipment purification and compression and other related technologies. The bottom line is that Petrobras total Choron shell exon Mobil and B. The world's most active oil companies in the field of using yen vessels are considered....

The valve engine (OHV) is one of the types of intraburner engines that this type performs better than the old flat head engine, and the valves are located above the cylinder block and below the cylinder head Housing....

In 1943, physicist Dr. John Maclay, in collaboration with John yenham Presper Eckert, an electrical engineer, began creating the first all-purpose electronic computer. The computer, which used nineteen thousand creative lamps in addition to electromechanical components, consumed 130,000 watts of energy and occupied 1,500 square feet, was named after ENIAC, an acronym for Electronic Numerical calculator and integrator. The ENIAC was installed in 1946 at the University of Pennsylvania and at the time was the most sophisticated electronic device in the world. The computer was able to perform three hundred multiplication operations per second and was able to perform 300-day manual labor in one day. The ENIAC computer weighed 30 tons. ENIAC left the round in 1956.ENIAC was originally designed and developed by the U.S. military to calculate missile fire؛ but was later used more publicly in the calculation of hydrogen bombs....

Variable timing system (VVT) valve opening and closing system in in-burner engines is variable and proportional to engine conditions. Variable timing system is a process of changing the time of departure and valves and more for better efficiency and efficiency.fuel savings and optimal exit of smoke. Further, this system, along with system variable amount of opening of the valve (the length or size of the valve comes out), or variable Valve Lift, the acronym VVL to be handled. There are many ways to achieve the performance of these systems, including mechanical devices-up to electro-hydraulics and systems without valves. It is also said that strict regulations have been published by the Association of mechanical engineers to require manufacturers of vehicles and motor vehicles to use the system....

GBU bombs or units of guided bombs، or precision guided bombs are a category of bombs usually headed or without an aerial engine that are directed by optical guidance laser guidance and the user of the GPS Global Positioning System.to the target and destroy their target. Most series bombs, such as JB-16 JB-10 JB-12 JB-15 JB-24, have trench-breaking or anti-fortification properties. These bombs have been used in the Iran-Iraq War, the Vietnam War, and other wars. In the Iran-Iraq war, Iran used JB-10 bombs against facilities and gathering sites of Iraqi forces....
