Seismic analysisSeismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit (see structural engineering) in regions where earthquakes are prevalent. As seen in the figure, a building has the potential to 'wave' back and forth during an earthquake (or even a severe wind storm). This is called the 'fundamental mode', and is the lowest frequency of building response.
Failure analysisFailure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability. According to Bloch and Geitner, ”machinery failures reveal a reaction chain of cause and effect... usually a deficiency commonly referred to as the symptom...”. Failure analysis can save money, lives, and resources if done correctly and acted upon.
Unix shellA Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language, and is used by the operating system to control the execution of the system using shell scripts. Users typically interact with a Unix shell using a terminal emulator; however, direct operation via serial hardware connections or Secure Shell are common for server systems.
Variety storeA variety store (also five and dime (historic), pound shop, or dollar store) is a retail store that sells general merchandise, such as apparel, auto parts, dry goods, toys, hardware, furniture, and a selection of groceries. It usually sells them at discounted prices, sometimes at one or several fixed price points, such as one dollar, or historically, five and ten cents. Variety stores, as a category, are different from general merchandise superstores, hypermarkets (such as those operated by Target and Walmart), warehouse clubs (such as Costco), grocery stores, or department stores.
Discount storeA discount store or discounter offers a retail format in which products are sold at prices that are in principle lower than an actual or supposed "full retail price". Discounters rely on bulk purchasing and efficient distribution to keep down costs. Discount stores in the United States may be classified into different types: Discount superstores such as Walmart or Target sell general merchandise in a big-box store; many have a full grocery selection and are thus hypermarkets, though that term is not generally used in North America.
PowerShellPowerShell is a task automation and configuration management program from Microsoft, consisting of a command-line shell and the associated scripting language. Initially a Windows component only, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. The former is built on the .NET Framework, the latter on .NET (previously .NET Core). Since Windows 10 build 14971, PowerShell replaced Command Prompt and became the default command shell for .
