The position of the Boolean algebra of logic with the onset of the computer age in mathematics happened again a new branch, which is naturally connected with the PC. More precisely, to create a computer that area was. And this is – Boolean algebra of logic or algebra. It was developed by J. Boole. Read more from Time Warner to gain a more clear picture of the situation. Boolean algebra, logic studies the zeros and ones and their functionality. This relies on the fact that the IT technology and chip tied to the two electrical pulses – the negative and positive. Filed under: Leslie Moonves. Because there was need for a Boolean algebra of logic, which includes various logical operations – disjunction, conjunction, negation, equivalence, etc.
So we decided on a representation of logic, now turn to the next step, which will increase our skills in this area. More information about the logical operations (truth table) Well, as in a simple algebra start with the basics – a popular logical operations, which enter the Boolean algebra Logic will not do. In mathematics, its operations are available, formed by the existing laws and axioms of algebraic and logical operations are built entirely on the laws of thought. TE Every operation has its own truth table, forming the resulting value, in other words the truth table records the results. For clarity of understanding to buy a notebook and take a look at the cell rear side. This multiplication table is a descriptive picture of the truth table. Now let's start looking at the main Boolean logic operations in detail. A bit of conjunction and disjunction Since this algebra is related to more programming, so I'll start writing the programmer, after all, realize conjunction and disjunction will have in a computer.
To denote the conjunction of consecutive symbols & &, in a simple considered the operation is multiplication, and is pronounced like I. disjunction opened portray characters 2 sticks. Disjunction is a logical addition operation and reads like OR. Disjunction and conjunctions is the most the first step in the study of Boolean algebra of logic, as well as in mathematics, addition and subtraction. But there is still a huge number of transactions that must be heard every programmer, but this article is an initial step in the development of themes, so do not go deeper.
Turbine steam turbine Leningrad Metal Plant (LMZ) PT-80/100-130/13 condensation with governing the selection of parameters and two-stage district heating production is intended for direct-drive generator. The turbine is single-shaft two-cylinder unit, consisting of HPC and LPC. Deaerirovanie feed water in the deaerator is operating at a pressure of 0.6 MPa. Steam consumption per unit at full load is 480 tons / hour Filling loss of condensate produced desalinated water coming from the HVO in the turbine condenser. At power installed a feed pump type PE 580-185/200-2. 4.PODGOTOVITELNYE work before the conservation work on the unit was developed, agreed and approved work program. Scrapbooks pipe samples c heating surfaces of boiler unit before its conservation have not been made.
Considering this factor, as well as properties to produce ODACON washing performance of deposits, the development program was made four stages conservation regime. Mounted metering pump with capacity of up to 30 l / h and pressure up to 10 bar. The metering pump membrane, the suction connected to the lower fitting plastic container V = 1,0 m3 emulsion ODACON, feed on the dosing pump was carried out on the feed pump suction line for dosing of hydrazine. The pump has a smooth adjustment of performance. Connect the pump-dispenser was made with flexible reinforced hoses.
Prior to the conservation of plant feed was tested emulsions ODACON. Noted that the dosing system is functioning properly and preservative ready for use. Workplace for laboratory analysis were prepared in him.laboratorii and with all the necessary him.reaktivami, him.posudoy and appliances. Pre-constructed calibration curve for determine the concentration of ODACON in accordance with the method. Works on CONSERVATION UNIT 80 MW. 5.1.Parametry unit prior to conservation: – load …………………………………. … 55Mvt. – Flow of feed water …………….. 300 t / h – temperature pit.vody ………………….. 240 0 C – the temperature of superheated steam ………
New trend for crusher industry in China In recent years, global economy enters to slowly adjustive period under the influence of global financial crisis. You may wish to learn more. If so, Mark Berger Villa Healthcare is the place to go. The development of the crusher (cone crusher) industry is not satisfying either in our country. What s worse, keen competition has always existed in large-scale crusher manufacturers that new-type crushing equipments hold a low share in the entire market. Therefore, it becomes essential to innovate to find a new way for the crushing manufacturers.To build a mining factory is to make a piece of earth clean, which is beneficial to people living area. As for mining ore exploring area, we are suggested that persist on green developing concept.
More attention should be paid to safety production, at the same time, clean production and environmental protection are also critical. Therefore, we should make every effort to improve recycling rate, reduces the amount of waste emission, bring down energy consumption and production increase operation benefits. It is not an easy thing to maintain a mining factory exploring. The relevant experts introduced that the present built main ore dressing projects, many of which adopt PL full-automatic control system, are international advanced as for the stone broken equipment, ore grinding equipment and flotation equipment so that it greatly improves ore disposal capability and useful ore recycling ability. In general, they invest 10 million RMB in ore processing line to build large capacity, high security and more standard residue storage and waste water treatment facilities. It doubtlessly provides reliable support for eco-environment in mining production steady. Now, China crusher manufacturing technology have been mature, there are many types and professional crushers in the market such, impact crusher, cone crusher, hammer crusher and so on.
In order to meet the new requirement of market, Henan Hongxing has made efforts to research and develop the new type energy-saving and high-efficiency crushing equipments. Our products can greatly reduces the power consumption and greatly improve the capacity. The innovation of information technology can make it possible to save the manpower, material and financial resources in the future development. The combination of information technology and engineering machinery and equipment will be inevitable. The numerical control technology has not only been used in the research and development new type machine, but also used in the current operation. The future period will be digital and digital operation gradually improvement and maturing process development
