                                                            Bluetooth

      

         Bluetooth is short radio waves that were developed by a group of electronics companies to allow any two devices - computers, cell phones, keyboards and many devices to carry out the process of contact alone without wires or cables or any intervention by the user. The system enables Bluetooth devices located within coverage waves to communicate with each other, so you can connect two devices located in different rooms, but Bluetooth should have a strong signal to cover this area.

          Bluetooth was developed in 1994 by Sven Mattisson and Haartsen Yap, who were working for Ericsson platforms in Lund, Sweden. Since 1980, companies try to make a new method based on the wireless connection. All these attempts were facing many difficulties are summarized in the additional consumption of electricity, and they face another problem because devices disturb each other.  The biggest problem is that there is no standard basis to work on it. In the meantime, it was believed that  infrared technology is the best solution for communication and wireless connectivity. To achieve this, the 30 companies and there founders, almost in the month of August of 1993 including HP, IBM, try to work together to establish a so-called IrDA Infrared Data Association.  This new technology was struggled with a difficult problem which need for optical communication between different devices as a prerequisite for the completion of the binding process.  Then, they joined with Ericsson Company to find a way to link wireless replaced with wired connectivity. As a result of the research of all companies (Ericsson, Nokia, IBM, Toshiba, and Intel) try to formulate a set of specifications agreed upon, and which is also derived from the knowledge and information from the IrDA. At the end they found the now invention which named Bluetooth.

      

        They developed Bluetooth because they need to solve some problems they faced by connecting some devises, before if they need to send files form computer to other computer they connect the computers by wires  sometimes the devises are far from each other so they need to invent a new thing to send files by wireless. Some digital devices like audio device need two connected with to wires and sometimes need 8 wires or 25 wires, so wireless connection will be easier.

       Bluetooth future looks strong, many companies trying to make Bluetooth reach far away to other device. Also cars companies trying to use Bluetooth in cars, so you can start the engine without switch. Sometimes when you send a file from device to other device, if the size of file is very big it’s taking a long time to reach, so the companies now working to solve this problem. As Hans Vestberg said in his interview “Bluetooth is future of wireless connection“(Hans Vestberg, President Ericsson and CEO).

      In conclusion I think Bluetooth is very important in our life, its make connection with devices very easy. I use Bluetooth to send music or picture form my lap to my mobile phone or from my friend phone to my phone. In future maybe everything will start working with Bluetooth.

Personal Reflection

We learn in this class summary an article from a newspaper. In the summary we should put the main ideas because it includes the importance in the article. If people read the summary and compare between the summary and the main article. But what if we should leave out some parts in the article, like names of people, some cities and years. Summarizing make the big article to small summary with a lot of main information. What is difficult in summarizing is when the article doesn’t have a lot of important ideas but all of it data’s. Also we learned how to do research from websites about any subject that teacher give it to as to search information about it. Also we learned how to find references and we put it in the summary. I think this course is very important for all students because it’s teach you how to take main ideas from an essay or anything that’s more than 500 to 600 words , so it’s easier to read the summary and understand what the subject is about.

                                                   The Masder Project

 The UAE Established Masdar, Abu Dhabi’s energy company, it coast Dh734.6 Million. Masder Abu Dhabi’s is the first of its kind in the region. There is not a lot of wind in the gulf, but they are working to design special turbine blades to take the benefits of light winds. Masder has been made the first wind farm, Shams1 and Nour1.The two solar plants are 100 megawatt. Masder will produce electricity of 100mw near the Saudi border. When the construction will be done, the wind farm in two years will generate the power. “Wind power is more challenging to develop in the GCC than solar power” (Yee, 2011). In the UAE, its limited because the nature of the wind. There a few days the weather becomes windy but not every time.

        Desert Survival: finding water

The Bedouin knew every detail of wells in the country. They know the source of water and the directions for navigation through the desert. People survived through the UAE’s sweltering summer by managing to eke out limited and hidden food. The Bedouin can know where water might be. Many followed the twittering or flight of birds. The well called by the name of man who dug it. The Bedouin kill the camel to drink the water stored in its stomach. Camels can store water for a longer time. People who live in desert replace water by the milk from camels and goats. The stored the water in satchels made of sheep or goatskin rot longer journeys. Bedouin can live more than 24 hours without water because their body adjusts itself through sweat.
