Fracture
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress (mechanics), stress. The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid. If a displacement develops perpendicular to the surface, it is called a normal tensile crack or simply a crack; if a displacement develops tangentially, it is called a shear crack, slip band, or dislocation. #Brittle, Brittle fractures occur without any apparent deformation before fracture. #Ductile, Ductile fractures occur after visible deformation. Fracture strength, or breaking strength, is the stress when a specimen fails or fractures. The detailed understanding of how a fracture occurs and develops in materials is the object of fracture mechanics. Strength Fracture strength, also known as breaking strength, is the stress at which a specimen structural integrity and failure, fails via fra ...

Packing And Cracking
Gerrymandering, ( , originally ) defined in the contexts of representative electoral systems, is the political manipulation of electoral district boundaries to advantage a party, group, or socioeconomic class within the constituency. The manipulation may involve "cracking" (diluting the voting power of the opposing party's supporters across many districts) or "packing" (concentrating the opposing party's voting power in one district to reduce their voting power in other districts). Gerrymandering can also be used to protect incumbents. Wayne Dawkins, a professor at Morgan State University, describes it as politicians picking their voters instead of voters picking their politicians. The term ''gerrymandering'' is a portmanteau of a salamander and Elbridge Gerry, Vice President of the United States at the time of his death, who, as governor of Massachusetts in 1812, signed a bill that created a partisan district in the Boston area that was compared to the shape of a myth ...

Software Cracking
Software cracking (known as "breaking" mostly in the 1980s) is an act of removing copy protection from a software. Copy protection can be removed by applying a specific ''crack''. A ''crack'' can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software generally involves circumventing licensing and usage restrictions on commercial software by illegal methods. These methods can include modifying code directly through disassembling and bit editing, sharing stolen product keys, or developing software to generate activation keys. Examples of ''crack''s are: applying a '' patch'' or by creating reverse-engineered serial number generators known as '' keygens'', thus bypassing software registration and payments or converting a trial/demo version of the software into fully-functioning software without paying for it. Software cracking contributes to the rise of online piracy where pirated software is distributed to end-users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Password Cracking
In cryptanalysis and computer security, password cracking is the process of guessing passwords protecting a computer system. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords. The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions restricted. Time needed for password searche ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Security
Computer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security. It consists of the protection of computer software, systems and computer network, networks from Threat (security), threats that can lead to unauthorized information disclosure, theft or damage to computer hardware, hardware, software, or Data (computing), data, as well as from the disruption or misdirection of the Service (economics), services they provide. The significance of the field stems from the expanded reliance on computer systems, the Internet, and wireless network standards. Its importance is further amplified by the growth of smart devices, including smartphones, televisions, and the various devices that constitute the Internet of things (IoT). Cybersecurity has emerged as one of the most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societi ...

Security Hacker
A security hacker or security researcher is someone who explores methods for breaching or bypassing defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, sabotage, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers. Longstanding controversy surrounds the meaning of the term "hacker". In this controversy, computer programmers reclaim the term ''hacker'', arguing that it refers simply to someone with an advanced understanding of computers and computer networks, and that ''cracker'' is the more appropriate term for those who break into computers, whether computer criminals ( black hats) or computer security experts ( white hats). A 2014 article noted that "the black-hat meaning still prevails among the general public". The subculture that has evolved around hackers is often referred to as the "co ...

Fracture Mechanics
Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials. It uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture. Theoretically, the stress ahead of a sharp crack tip becomes infinite and cannot be used to describe the state around a crack. Fracture mechanics is used to characterise the loads on a crack, typically using a single parameter to describe the complete loading state at the crack tip. A number of different parameters have been developed. When the plastic zone at the tip of the crack is small relative to the crack length the stress state at the crack tip is the result of elastic forces within the material and is termed linear elastic fracture mechanics (LEFM) and can be characterised using the stress intensity factor K. Although the load on a crack can be arbitrary, in 1957 G. Irwin foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safe Cracking
Safe-cracking is the process of opening a safe without either the combination or the key. Physical methods Safes have widely different designs, construction methods, and locking mechanisms. A safe cracker needs to know the specifics of whichever will come into play. Lock manipulation Lock manipulation is a damage-free, combination-based method. A well known surreptitious bypass technique, it requires knowledge of the device and well developed touch, along with the senses of sight and possibly sound. While manipulation of combination locks is usually performed on Group 2 locks, many Group 1 locks are also susceptible. The goal is to successfully obtain the combination one number at a time. Manipulation procedures vary, but all rely on exploiting mechanical imperfections in the lock to open it, and, if desired, recover its combination for future use. Similar damage-free bypass can also be achieved by using a computerized auto-dialer or manipulation robot in a so-called brute-fo ...
