Noise reductionNoise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio. All signal processing devices, both analog and digital, have traits that make them susceptible to noise.
Information scienceInformation science (also known as information studies) is an academic field which is primarily concerned with analysis, collection, classification, manipulation, storage, retrieval, movement, dissemination, and protection of information. Practitioners within and outside the field study the application and the usage of knowledge in organizations in addition to the interaction between people, organizations, and any existing information systems with the aim of creating, replacing, improving, or understanding the information systems.
Acoustic quietingAcoustic quieting is the process of making machinery quieter by damping vibrations to prevent them from reaching the observer. Machinery vibrates, causing sound waves in air, hydroacoustic waves in water, and mechanical stresses in solid matter. Quieting is achieved by absorbing the vibrational energy or minimizing the source of the vibration. It may also be redirected away from the observer. One of the major reasons for the development of acoustic quieting techniques was for making submarines difficult to detect by sonar.
BarotselandBarotseland (Lozi: Mubuso Bulozi) is a region between Namibia, Angola, Botswana, Zimbabwe including half of eastern and northern provinces of Zambia and the whole of Democratic Republic of Congo's Katanga Province. It is the homeland of the Lozi people or Barotse, or Malozi, who are a unified group of over 46 individual formerly diverse tribes related through kinship, whose original branch are the Luyi (Maluyi), and also assimilated Southern Sotho tribe of South Africa known as the Makololo.
ZambeziThe Zambezi (also spelled Zambeze and Zambesi) is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers , slightly less than half of the Nile's. The river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean.
ZambiaZambia (ˈzæmbiə,_ˈzɑːm-), officially the Republic of Zambia (Bemba: Icalo ca Zambia; Tonga: Cisi ca Zambia; Tumbuka: Chalo cha Zambia Lozi: Naha ya Zambia; Nyanja: Dziko la Zambia), is a landlocked country at the crossroads of Central, Southern and East Africa. It is typically referred to being in South-Central Africa and is culturally Southern African. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the north-east, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west.
Victoria FallsVictoria Falls (Lozi: Mosi-oa-Tunya, "Thundering Smoke"; Tonga: Shungu Namutitima, "Boiling Water") is a waterfall on the Zambezi River in southern Africa, which provides habitat for several unique species of plants and animals. It is located on the border between Zambia and Zimbabwe and is one of the world's largest waterfalls, with a width of . Archeological sites and oral history describe a long record of African knowledge of the site.
Transmission systemSee Transmission (mechanics) for a car's transmission system In telecommunications, a transmission system is a system that transmits a signal from one place to another. The signal can be an electrical, optical or radio signal. The goal of a transmission system is to transmit data accurately and efficiently from point A to point B over a distance, using a variety of technologies such as copper cable and fiber optic cables, satellite links, and wireless communication technologies.
