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
Ticket No1 1)The characteristic is called output characteristic or volt-ampere charateristic of a Rectifier Diode. 2)Rectifier Diode. 3) A is called Anode and C is called Cathode. An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing. If the current in a diode is too large, excessive heat will destroy the device. Even approaching the burnout current value without reaching it can shorten its life. Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used as a rectifier. Another entry of interest in the da
Thesis “How is it possible to calculate IT security effectiveness?” Kristjan Kivimaa August 2022 1 Abstract In IT Security world, there is lack of available, reliable systems for measuring security levels/posture. They lack the range of quantitative measurements and easy and fast deployment, and potentially affects companies of all sizes. Readily available security standards provide qualitative security levels, but not quantitative results – that would be easily comparable. This deficiency makes it hard for companies to evaluate their security posture accurately. Absence of security metrics makes it complicated for customers to select the appropriate measures for particular security level needed. The research question for this research project is – “How is it possible to calculate IT security effectiveness?”. The aim of this research is to use this reference m
Voyage Planning Voyage Planning The key elements of the Voyage Plan are: Appraising all relevant information Planning the intended voyage Executing the plan taking account of prevailing conditions Monitoring the vessel’s progress against the plan continuously Planning The detailed voyage or passage plan should include the following factors: 1) the plotting of the intended route or track of the voyage or passage on appropriate scale charts: the true direction of the planned route or track should be indicated, as well as all areas of danger, existing ships' routeing and reporting systems, vessel traffic services, and any areas where marine environmental protection considerations apply; 2) the main elements to ensure safety of life at sea, safety and efficiency of navigation, and protection of the marine environment during the intended voyage or passage; such elements should include, but not be limited
