Injective Function
In mathematics, an injective function (also known as injection, or one-to-one function) is a function that maps distinct elements of its domain to distinct elements; that is, implies . (Equivalently, implies in the equivalent contrapositive statement.) In other words, every element of the function's codomain is the image of one element of its domain. The term must not be confused with that refers to bijective functions, which are functions such that each element in the codomain is an image of exactly one element in the domain. A homomorphism between algebraic structures is a function that is compatible with the operations of the structures. For all common algebraic structures, and, in particular for vector spaces, an is also called a . However, in the more general context of category theory, the definition of a monomorphism differs from that of an injective homomorphism. This is thus a theorem that they are equivalent for algebraic structures; see for more details. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault Injection
In computer science, fault injection is a testing technique for understanding how computing systems behave when stressed in unusual ways. This can be achieved using physical- or software-based means, or using a hybrid approach. Widely studied physical fault injections include the application of high voltages, extreme temperatures and electromagnetic pulses on electronic components, such as computer memory and central processing units. By exposing components to conditions beyond their intended operating limits, computing systems can be coerced into mis-executing instructions and corrupting critical data. In software testing, fault injection is a technique for improving the coverage of a test by introducing faults to test code paths; in particular error handling code paths, that might otherwise rarely be followed. It is often used with stress testing and is widely considered to be an important part of developing robust software. Robustness testing (also known as syntax testing, fuz ...

Drug Injection
Drug injection is a method of introducing a drug into the bloodstream via a hollow hypodermic needle, which is pierced through the skin into the body (usually intravenously, but also at an intramuscular or subcutaneous location). Intravenous therapy, a form of drug injection, is universally practiced in modernized medical care. , there were 13.2 million people worldwide who self-administered injection drugs outside of medical supervision, of which 22% are from developed countries. A wide variety of drugs are injected, often opioids: these may include legally prescribed medicines and medication such as morphine, as well as stronger compounds often favored in recreational drug use, which are often illegal. Although there are various methods of taking drugs, injection is favoured by some people as the full effects of the drug are experienced very quickly, typically in five to ten seconds. It also bypasses first-pass metabolism in the liver, resulting in higher bioavailability and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Injection (economics)
Injections in economics are introductions of income into circular flow from sources outside households and businesses, such as additions to investment, government expenditure and exports."The Nature of the Economy," ''Reserve Bank of Australia,'' https://www.rba.gov.au/education/resources/delivery-notes/pdf/the-nature-of-economy.pdf. Retrieved 3 Oct. 2022. When a central bank makes a short-term loan to a member institution, it is said to be injecting liquidity. In the United States, the Federal Reserve maintains a target federal funds rate for banks to loan money overnight. If the lending banks are unwilling to offer enough credit at this rate, the central bank may step in and make loans itself through the discount window. In this role, the central bank is operating as the lender of last resort and is said to be injecting liquidity Liquidity is a concept in economics involving the convertibility of assets and obligations. It can include: * Market liquidity, the ease with which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Sufferer & The Witness
''The Sufferer & the Witness'' is the fourth studio album by American punk rock band Rise Against, released on July 4, 2006. A melodic hardcore album, it comprises thirteen tracks that focus on melody, catchy hooks, and rapid-paced tempo. Social and political issues as well as the concept of self-reflection constitute the majority of the lyrical content. Dissatisfied with ''Siren Song of the Counter Culture'' (2004) producer Garth Richardson, the band members decided to record their next album with Bill Stevenson and Jason Livermore, the duo that worked on their 2003 album ''Revolutions per Minute''. ''The Sufferer & the Witness'' sold 48,327 copies in its first week of release, and charted in seven countries, including the United States where it entered at position ten on the ''Billboard'' 200. Critical appraisal was mainly positive, with reviewers complimenting Rise Against's ability to mature in its sound while simultaneously retain its punk roots. Reviewers also highlighte ...

Injected (band)
Injected was an American rock band, inspired by acts such as Helmet, Refused and Quicksand. History After forming in the mid-1990s by a group of high school friends and spending years gathering a strong following on the Atlanta rock scene, Injected released its major label debut, '' Burn It Black'', on February 26, 2002 on Island Records. The album was produced by another Atlanta native, former Marvelous 3 frontman and ''Rolling Stone'' noted producer Butch Walker (Sevendust, Rock Star Supernova, Avril Lavigne). Injected made a video for its first single, "Faithless", and the song became a top 20 single on modern and active rock charts, reaching as high as No. 3 on MTV's rock countdown. Album cuts such as "I-IV-V" and "Burn It Black" were also included on soundtracks for films such as ''The Fast and the Furious'', ''Spider-Man'', ''The Scorpion King'', among others. Injected spent years touring the country in support of the record, and played venues large and small with ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SQL Injection
In computing, SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker). SQL injection must exploit a security vulnerability in an application's software, for example, when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database. SQL injection attacks allow attackers to spoof identity, tamper with existing data, cause repudiation issues such as voiding transactions or changing balances, allow the complete disclosure of all data on the system, destroy the data or make it otherwise unavailable, and become administrators of the database server. In a 2012 study, it was observed that the average w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Injection
Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks. The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network. The most common type is Wi-Fi security, which includes Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). WEP is an old IEEE 802.11 standard from 1997. It is a notoriously weak security standard: the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP was superseded in 2003 by WPA, a quick alternative at the time to improve security over WEP. The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement. WPA2 uses an encryption device that encrypts the network with a 256-bit key; the longer key length improves security over WEP. Enterprises of ...

Email Injection
Email injection is a security vulnerability that can occur in Internet applications that are used to send email messages. It is the email equivalent of HTTP Header Injection. Like SQL injection attacks, this vulnerability is one of a general class of vulnerabilities that occur when one programming language is embedded within another. When a form is added to a Web page that submits data to a Web application, a malicious user may exploit the MIME format to append additional information to the message being sent, such as a new list of recipients or a completely different message body. Because the MIME format uses a carriage return to delimit the information in a message, and only the raw message determines its eventual destination, adding carriage returns to submitted form data can allow a simple guestbook to be used to send thousands of messages at once. A malicious spammer could use this tactic to send large numbers of messages anonymously. More information on this topic, including ...

Injection (medicine)
An injection (often and usually referred to as a "shot" in US English, a "jab" in UK English, or a "jag" in Scottish English and Scots) is the act of administering a liquid, especially a drug, into a person's body using a needle (usually a hypodermic needle) and a syringe. An injection is considered a form of parenteral drug administration; it does not involve absorption in the digestive tract. This allows the medication to be absorbed more rapidly and avoid the first pass effect. There are many types of injection, which are generally named after the body tissue the injection is administered into. This includes common injections such as subcutaneous, intramuscular, and intravenous injections, as well as less common injections such as intraperitoneal, intraosseous, intracardiac, intraarticular, and intracavernous injections. Injections are among the most common health care procedures, with at least 16 billion administered in developing and transitional countries each yea ...
