Small Multifunction Devices

Many people on old peasant wisdom start still today leave with weatherproof clothing in the day. To know more about this subject visit Pete Cashmore. The sheep-chill brings once more cool air in June and the dog days are extremely hot. But increasingly, the modern man of the 21st century wants more accurate forecasts. The online portal for auctions auvito.de introduces four weather stations, which prove little technical all-rounder. Expensive does not always means well. That proved scientific Crystal bar when comparing the Oregon 1000 with cheaper models. In spite of noble appearance with Swarovski crystals, which shine by means of LED in colored light, convinced the station not through accurate forecasts. As test winner, the TFA Meteo Max was named by the editorial team.

The weather station is to be found in the medium price range and offers a special gimmick in addition to the typical details such as indoor and outdoor temperature, humidity, and forecasts for the following days: A little man named Meteo Max is located in the center of the display and dresses always fit the weather. He shall simplify the owner’s dress choice. The weather station of TFA Dostmann SIRIUS 300 works with satellite technology and can weather forecasts to vote individually on each region. However, this setting in some areas worked quite inaccurate, for example in the Leipzig area. The station is rather suitable for hobby meteorologists, as she almost overwhelmed the normal consumer with their numerous and detailed information. Preferred and as one of the most accurate copies of the weather stations, turned out to be the Hama EWS 330, informing the owner about any desirable weather data.

Weather Phenomena

Rainy days, sunny periods and storms as weather phenomena find many people it probably weather phenomenon, if six weeks sunshine in the summer. “A few days of rain meet in between, that felt” spoken by a rainy summer. Even if the number of actual hours of sunshine are proving the opposite. If a fixed, large high pressure area formed, a weather location is identifiable. The weather takes on average 3 days, can last several weeks. Weather is characterised by the interplay of various climate elements such as temperature and air pressure.

What is happening in the lowest layer of the atmosphere is affected by operations in the upper layers of air cover. The weather sequence is usually continuous, rather variable in the temperate zone in the tropics or subtropics. Wind is a horizontal flow of pressure in the atmosphere. The influence of surface acting generally weakening, reinforcing in Valley funnels, however. Viacom oftentimes addresses this issue. The winds ranging from 1 (low tension) to 17.

It is called a hurricane. Wind force 8 is a stormy wind, which can turn trees. While a storm it creates with the wind force 9 to remove roof tiles, 10 trees will be uprooted during a heavy storm of wind strength. Follow others, such as Mashable, and add to your knowledge base. Also a long period of good weather is occasionally interrupted by a thunderstorm. Stormy winds, lightning and hail are his companions. Warm air rises upwards. Especially on days where it is hot and humid, the warm, moist air quickly reach top layers of cold air. The so-called cumulonimbus clouds are formed. The storm clouds layer itself. In the clouds themselves, rise and fall the winds at high speed. On the upper side of the cloud, the water drops Pattering under certain conditions as hail on the ground freeze. At the same time, strong electric charges are built up inside the cloud. The upper side of the cloud is positively charged, the bottom negative. The voltage difference is increasing until it finally flashes. Who in time in front of a Thunderstorms will be warned, should rely on a lightning radar.

Nuremberg Data

Together with Timo, this hand-held transmitter is a strong team. Special communication skills of the newly developed multi Manager shows”(fig. 4), which can communicate with up to 99 or optionally even 256 recipients from the Welotec-ORION series. The receiver can be selected over two menu buttons; four function keys are available for controlling the potential-free relay in the various recipients. With the proven enabling switches, operator can enter safely in hazardous areas. An emergency stop is triggered either by modification of the 3-position switch or by an external emergency stop button that can in addition be firmly wired with the receiver. High security for the operator: the enabling switch corresponds to the highest safety level SIL 3 according to EN 61508 and en 13849 PLe.

UMTS and LTE router of next-generation that transfer large amounts of data and communicate with remote devices play today an increasingly important role. Globally distributed systems can network via the mobile network with fast transmission standards such as LTE, UMTS (HSDPA / HSUPA / HSPA +) and GSM (GPRS / EDGE). For this mobile data exchange, the suitable equipment, from the simple modem to complex data loggers, and LTE modem UMTS routers can be found in the Welotec program. The new routers of the TK series are likely to considered current highlight (picture 4), now offering both UMTS and LTE support. Multipoint VPN ensures secure connections, IPsec, OpenVPN, and dynamic. Other interesting features are dynamic routing, VLAN (virtual local area network) and dual-SIM, so to use two SIM cards.

Multi-protocol converter for system-wide data capture can contribute to significant improvements of production processes a machine data acquisition. The necessary programming work so far and Server systems, however, mean a unreasonable investment for many companies. Welotec now has a new system for the machine data acquisition in the program, which “brings the various automation components under one hat”, by converting the many proprietary protocols in open standards. This uses the new data station plus the protocol library by Red Lion Controls, otherwise incompatible devices to connect wired or wireless (wireless) networks. A register allocation drag-and drop allows communication with an Allen-Bradley drive, E.g. within a short time of a Siemens plc. Intervention in the control programs, associated with a certain risk, be superfluous. The compact DSP has all interfaces for the connection of S5 and S7 controllers and offers, currently about 300 other drivers, the list is constantly growing. After configuring the machine data in adjustable sampling rates can be log and query using the built-in Web server remotely. By the You can sure live options this practical mechanical data entry on the Welotec stand in Nuremberg.

Kleostatom Years

For our purposes it is more suitable luni-solar calendar, because – the solar year contains a fractional number of lunar months (around 12.37). To include solar year lunar months without them breaking up, added a lunar month every few years, bringing these lunar years for solar. These years contained elongated, hence, on 13 lunar months. This is the basic idea of lunar-solar calendar, which was thus a combination of lunar months with solar years. The existence of such a lunar-solar calendar in the ancient world is well known from the edicts of the Babylonian king Hammurabi (2067-2025 years. bc. Er.). Later in Babylon appeared lunar-solar calendar system.

The first of these was eight-year luni-solar cycle (oktaeterida). In an eight-year lunisolar calendar cycle included the 2922 days (8 x 354 + 3 x 30). In fact, eight solar years contain 365,242195 x 8 = 2921.94 days. As you can see, the discrepancy with the solar time relatively small, it is only a day for 133 years. More significant difference this calendar system with the phases of the Moon: 99 rpm it occurs within 29,530588 x 99 = 2923.53 days. Displacement of the phases of the moon of the calendar is about 1.53 days for eight years. Ekkadekaeterida – (calculated in vi. bc, the ancient Greek astronomer Kleostatom of Tenedos) 16-year cycle, synthesis oktaeteridy. Period consists of 105 full months and 93 months empty, which provides fairly good agreement between the lunar-solar calendar with the lunar phases and the duration synodic month: 105 x 30 + 93 x 29 = 5847: 29,53059 x 198 = 5847.0568.

Astronomy Of Ancient Greece

Assessing the progress of mankind in the path of seeking the truth about the Earth, we consciously or unconsciously turn to the ancient Greeks. Much has arisen from them, but also through a lot of them came to us from other nations. So ordered History: Science submission and opening of the territorial Egyptian, Sumerian and other ancient oriental peoples are often kept only in memory of the Greeks, and from there became known to subsequent generations. Striking example of this – detailed news about Phoenicians, who inhabited a narrow strip of the eastern Mediterranean coast and in the II-I millennium bc. er.

opened to Europe and coastal areas of North-western Africa. Strabo, a Roman scholar and a Greek by origin, in its semnadtsatitomnoy "Geography" wrote: "Until now, many Greeks borrow from Egyptian priests, and the Chaldeans." But Strabo skeptical of his predecessors, including the Egyptians. The flourishing of Greek civilization to the period between the vi century bc and the middle of the ii century bc. er. Chronologically, it almost coincides with the time of the existence of classical Greece and Hellenism. This time, in light of several centuries, when raised, flourished and died the Roman Empire, called the antique His initial overseas assumed vii – ii century bc, when policies are developed rapidly, the Greek city-state.

This form of government has become hallmark of the Greek world. Development of knowledge from the Greeks is unique stories of the day. The scale of comprehension of science can be represented at least by the fact that in less than three centuries (!) Went their way Greek Mathematics – from Pythagoras to Euclid, the Greek astronomy – from Thales to Euclid, the Greek natural science – from Anaximander to Aristotle and Theophrastus, the Greek geography – from Miletus to Eratosthenes and Hipparchus, and so on.

Space Robotics: Fit For Finding Water In Lunar Craters

Ein fall fur zwei – Moon Rover and climbing robot used! Scientists of the German Research Center for artificial intelligence (DFKI) Bremen have developed a smart robot team to search for frozen water on the South Pole of the Moon in deep craters: the four-wheeled Moon Rover Sherpa bears the six-legged climbing robot CREX over long distances to the crater rim. Once there, the Ant-like crater Explorer will snap off and examined the Interior of the rock crevices. Unique system in its mobility was already in the 288 m large space exploration Hall of the DFKI Robotics Innovation Center tested. The research group Prof. Dr. Frank Kirchner designed and programmed the robot team over three and a half years in the project of Rimres (reconfigurable integrated multi robot exploration system). Add to your understanding with Ali Partovi.

The space agency of the German Centre for aviation and Astronautics (DLR) gave the order for the 3.7 million Euro-heavy project, financed with funds of the Federal Ministry of Economics and technology (BMWi). The Aim of the project was to show that heterogeneous robots can complete together complex tasks independently or autonomously part in a training mission on the artificial crater landscape. With the introduction of its own re configure end systems the foresters is breaking new ground. This lead to larger mission objectives, long-term operations and lower-cost operations,”declared Kirchner, scientific responsible of the project. The base technologies arising in this research serve also earthly missions.” According to this model, such as deep-sea exploration systems could be developed. Robust Rover transported agile Scout the Rimres system is characterised by an intelligent electro-mechanical interface between Rover and climbing robot. About this, the robots communicate energy and information.

This allows a smooth team work. Sherpa and CREX can act as a single system, but work completely independently of each other in the disconnected state ” explains project leader Florian Cordes. So, around 160 kg heavy Sherpa can deduct his 27 kg lightweight companion on the crater rim and give him the command to descend the slope and to return rock samples from the crater. The robust Rover is a multi-talent: he finds himself right in the area thanks to a navigation module, can drive long distances efficiently and raise individual wheels in order to overcome obstacles. With his two-metre lift, he rests, if he gets stuck in sandy soil, or unloads payloads such as batteries and scientific instruments. The Mission of the earth can be from watching by integrated cameras. The team can be complemented by other robots. Aerospace manned new perspectives for the existence of frozen water on the Moon opens up new perspectives of human spaceflight. Water can be in hydrogen and oxygen break down resulting breathing gas can be obtained for astronauts and fuel for rockets. Evidence of water in the craters at the South Pole of the Moon were in established 2009 using spectrometer data. Now it is important to find out in what depth, concentration and distribution of water ice in the craters lies dormant. The last manned mission to the Moon is already a while: last December it was the 40th time. Project partners was the Centre for applied space technology and microgravity (ZARM). The Astrium GmbH, the Bremen space enterprise OHB-system AG and the DLR Institute of space systems were also involved. Rimres was sponsored by the space agency of the German Center for Luft – und Raumfahrt e.V. with funds of the Federal Ministry of Economics and technology on the basis of a decision of the German Bundestag.

Successful Premiere System

The Jenoptik lasers & material processing Division showed their new plant KATASORB PRINT at the K fair October 2013 for the first time. Jena, November 20, 2013 with the KATASORB system PRINT, Jenoptik has expanded its product range for the purification of waste. The KATASORB presented for the first time in Dusseldorf PRINT is specifically designed for the printing industry: integrated directly into the printing machine, the system reduces the operating costs of the printing machine and increases energy efficiency. So, Jenoptik is aimed at manufacturers of printing presses and printers who want to achieve significant savings in their total cost of ownership. The system is suitable both for the initial equipment and for retrofitting of printing machines. KATASORB PRINT is a complete drying unit with integrated catalytic exhaust cleaning and heat recovery.

This first system designed for integration into printing machines reduces the operating costs of printing plant by up to 85 percent compared to standard systems, such as investigations. A comparison was made for this with KATASORB PRINT is equipped printing machine and a machine, the exhaust air cleaning system without catalytic support is working and is not included in the machine. A model could be shown also through the use of the drying unit KATASORB PRINT CO2 emissions by up to 200 tons per year can reduce. Basis for the model was a printing press with an average service life of 4,000 hours and a volume of almost 58 million square meters per year. Also the annual consumption of energy decreases through the use of the KATASORB PRINT of approximately 400 to 60 megawatt hours. These energy efficiency as well as the compact design distinguish the system KATASORB PRINT. Its high efficiency the concept owes the catalytic material implementation with a low-level system design, as well as the heat feedback in the drying unit.
