2 Photographic camera & photography (SEBA) Photographic camera is an equipment used for taking photographs (usually consisting of a lightproof box with a lens at one end and light-sensitive film at the other) Photography is The art or practice of taking and processing photographs. 3 Context of the creation of the camera (CARLA) The camera has been used since before Christ. The impact in society the emergence of the camera was important and shocking because it helped us capture important moments in time that can no longer be repeated and helped a lot in the field of communication. The first models of cameras were used in the years before Christ where they were used to see closely objects. After its emergence was marked a before and after in history because thanks to this artefact can capture exact moments in which a event happened. Advancing in history have improved the types of cameras, passing cameras that took several min

Trojan-Notifier - notification of a successful attack Trojans are designed for this type of message master "on the infected computer. Major trends Trojans In programs related to the class of Trojans, to date, the following main trends: Significant increase in the number of spyware stealing confidential banking information.New versions of these programs appear dozens per week and are very diverse and operating principles. Some of them are limited to just a collection of all input from the keyboard data and sending them by e-mail to the attacker. The most powerful can give the author full control over an infected machine to send megabytes of data collected on the remote server to receive commands from there for further work. Pursuit of total control over infected computers. This is reflected in their association in a zombie network, controlled from a single center Use of infected machines to send spam through them, or launch attacks
is useful for: · data with irregular arrival times (human input/output) · transmission line with long idle · Frame synchronization schemes: receiving station. It tells the receiving NIC in which buffer states · used when relatively coarse synchronization is ok e.g. terminal & keyboard I/O Async. ·Data Link Control ProtocolsoHDLC Within HDLC, there are three types of to put this information. transmission is characterized by: · no direct clock information between receiver and transmitter · stations defined:1. Primary Station - this completely controls all data link operations The SSAP, or Source Service Access Point is analogous to
4 Analog Interfacing to Embedded Microprocessors code, with all the new characteristics of the new sensor handled in the remote microcontroller. Another factor to consider in calibration is the human element. If a system requires calibration of a sensor in the field, does the field technician need arms twelve feet long to hold the calibration card in place and simultaneously reach the “ENTER” key on the keyboard? Should a switch be placed near the sensor so calibration can be accomplished without walking repeatedly around a table to hit a key or view the results on the display? Can the adjustment process be automated to minimize the number of manual steps required? The more manual adjustments that are needed, the more opportunities there are for mistakes. Bandwidth Several years ago, I worked on an imaging application. This system was to capture data using a CCD (Charge Coupled Device) image sensor
clay, preferably in a mix with 30% sand to reduce shrinkage. The clay is first ground and mixed with water to the desired consistency. The clay is then pressed into steel moulds with a hydraulic press. The shaped clay is then burned at 1000 °C to achieve strength. In modern brickworks, this is usually done in a continuously fired tunnel kiln, in which the bricks are fired as they move slowly through the kiln on conveyors, rails, or kiln cars, which achieves a more consistent brick product. The bricks often have lime, ash, and organic matter added, which accelerates the burning process. Dry pressed bricks (slide 10) The dry press method is similar to the soft mud brick method, but starts with a much thicker clay mix, so it forms more accurate, sharper-edged bricks. The greater force in pressing and the longer burn make this method more expensive. Extruded bricks (slide 11) For extruded bricks the clay is mixed with 20% water. This mixture is forced through a die to

Protecting endangered species will make a difference in humans' life In the nature of humankind it is natural to hunt animals. However, nowadays hunting endangered species will make humans be just killers, because it is not necessary to kill something just to have a trophy on the wall at home. People can be proud of what they have done, but decreasing the population of a species largely will cause the specific animal breed to go extinct faster than it would happen via natural causes. Therefore, humans should stop hunting endangered species to slow down their extinction, as these species offer balance in the wildlife, are used without purpose in medicine, and may even reduce poverty. Species on the brink of extinction affect us more than we realize. Sure, pandas are cute, and rhinos are fun to look at, but is there anything more to that? All animals and plants form a very important part of our ecosystem that also includes our lands and waters. Remove one part from the environment
