Another stone megalithic structure exists which consists of a central radial stone and several other stones in the distance. In interpreting this Brophy found that the lines made to these stones from the radial stone match the spots in the sky where the various stars marked by the center stones in the calendar circle at the time they rose as the vernal equinox heliacal rising. In analyzing the varying distances, mulling through assumptions such as that they represented the brightness of the stars, he inadvertently found that they matched the distance of the stars from Earth on a scale of 1 meter = .799 light years within the margin of error for astronomical distances calculated today.
Video card
In computing, a video card, graphics card or graphics accelerator is a special circuit board that controls what is shown on a computer monitor and calculates 3D images and graphics.
A video card can be used to display a two-dimensional (2D) image like a desktop, or a three-dimensional (3D) image like a computer game. Computer-Aided Design (CAD) programs are often used by architects, engineers and designers to create 3D models on their computers. If a computer has a very fast video card, the user can create very detailed 3D models.
Most computers have a basic video and graphics capabilities built-in to the computer's motherboard. These "integrated" video chips are not as fast as in separate or "discrete" video cards. Normally, they are fast enough for basic computer use and old or simple computer games on lower graphic settings. If a computer user wants faster and/or more detailed graphics, a video card can be installed.
Video cards have their own processor (called a Graphics Processing Unit or GPU). The GPU is distinct from the main computer processor (called the Central Processing Unit or CPU). The CPU's job is to process the calculations needed to make the computer function. The GPU's job is to handle graphics calculations. 3D graphics calculations take a lot of CPU power, so having a video card to handle the graphics calculations lets the CPU work on other things like running computer programs.
Video cards also have their own memory, separate from the main computer memory. It is usually much faster than main computer memory, too. This helps the GPU do its graphics calculations even faster. Most video cards also can make one computer use more than one computer monitor at one time. Graphics manufacturers Nvidia and AMD (Advanced Micro Devices) have special technologies that allow two identical cards to be linked together in a single computer for much faster performance. Nvidia calls their technology and AMD calls their technology . Some modern graphics cards can even process physics calculations to create even more realistic-looking 3D worlds.
Video cards typically connect to a motherboard using the Peripheral Component Interconnect (PCI), the (AGP) or the (PCI Express or PCI-E). PCI-E is the newest and fastest connection; which nearly all modern video cards and motherboards have this connection. Before PCI-E was used, AGP was the standard connection for video cards. Before AGP, video cards were designed for PCI (sometimes called "regular" PCI).
In early computing years, graphics processing was very basic and could be done by the CPU along with all the other processing. However, as computer games advanced and started using 3D graphics, the CPU had too much to do and CPU-makers could not keep up on making them faster. Eventually, video cards, with their own GPU, were invented to solve this problem. This lets the CPU do more of its own work since it does not have to spend any time on advanced graphics calculations; it can simply pass these calculations off to the GPU to be done.
The first video cards connected to the motherboard via the ISA connection. The first popular non-IBM video cards were manufactured by a company called Hercules Computer Technology, Inc. Throughout the years, the importance of video cards has grown. As they evolved, a new connection standard was developed called Advanced Graphics Port (AGP). This was the first motherboard connection designed exclusively for video cards. It was much faster at transferring information between the video card and the rest of the computer. Eventually, the AGP connection became outdated, and a new connection, called PCI Express (PCI-E), became the standard for video cards. Most video cards manufactured today use PCI-E to connect to the motherboard.
Barahona, Dominican Republic
Barahona, also known as Santa Cruz de Barahona, is the head municipality of the Barahona province, on the southwest of the country.
It is the largest city of the Dominican southwest and the centre of the region.
The municipality had, in 2010, a total population of 62,054: 30,799 men and 31,255 women. The urban population was of the total population, one of the most urban municipality in the country.
Since the 18th century, the region was occupied by fishermen and people that came here to cut trees. When Toussaint L'Ouverture took the eastern part of the Hispaniola island in the name of France, he gave the order to create the town of Barahona in 1802 as part of the Ozama Department.
After the Independence in 1844, Barahona was a military post of the Azua Province.
In 1858, Barahona was elevated to the category of municipality. When the province was created in 1881, Barahona was made its head municipality.
The city of Santa Cruz de Barahona is in a plain along the coast, in the lower valley of the Yaque del Sur river. Part of the municipality is on the mountains of Sierra de Bahoruco.
Barahona is at to the west of Santo Domingo. The limits of the municipality are the municipality of Fundación to the north, the Caribbean Sea to the east, the municipality of La Ciénaga to the south and the municipality of Cabral to the west.
Barahona has a tropical wet and dry/savanna climate (Köppen climate classification : Aw). The climate on the mountains of the Sierra de Baoruco, where there are some rainforests, is cooler and more wet.
The average amount of rainfall for the year in the city is . Most rains fall during the end of summer. The month with the most precipitation on average is October with of rainfall, followed by May with .
The driest season is winter. The month with the least rainfall on average is February with an average of and the second is January with .
Barahona is in a warm region; the average temperature for the year is . The warmest months, on average, are July and August with an average temperature of . The coolest months on average are December, January and February, with an average temperature of .
The municipality of Santa Cruz de Barahona has three municipal districts; these are:
The main economic activity of the province is agriculture; the main product in the municipality is a very good coffee ("Barahona Type Coffee"), grown in the mountains of Eastern Bahoruco.
There are also some important industries, mainly to produce textiles to send to other countries, and sugar in the "Ingenio Barahona" ("Barahona Sugar Factory").
There is a port in the city; it is used to send coffee and sugar to other countries.
Sindh
Sindh () () is a province in Pakistan. The provincial capital of Sindh is Karachi. Sindh has a population of 30 million people and an area of 54,407 mi² or (140,914 km²); in terms of area the provincial region of Sindh is greater in area than Greece but smaller than Tajikistan.
