Security Parameter Index
The Security Parameter Index (SPI) is an identification tag added to the header while using IPsec for tunneling the IP traffic. This tag helps the kernel discern between two traffic streams where different encryption rules and algorithms may be in use. The SPI (as per RFC 2401) is a required part of an IPsec Security Association A security association (SA) is the establishment of shared security attributes between two network entities to support secure communication. An SA may include attributes such as: cryptographic algorithm and mode; traffic encryption key; and paramet ... (SA) because it enables the receiving system to select the SA under which a received packet will be processed. An SPI has only local significance, since it is defined by the creator of the SA; an SPI is generally viewed as an opaque bit string. However, the creator of an SA may interpret the bits in an SPI to facilitate local processing. This works like port numbers in TCP and UDP connections. What it mea ...

Swiss Performance Index
The Swiss Performance Index (SPI) is a wide total-return index that tracks equity primarily listed on SIX Swiss Exchange with a free-float of at least 20%, and excluding investment companies. The index covers large, mid and small caps and is weighted by market capitalization. Most constituents, although not all, are domiciled in Switzerland or the Principality of Liechtenstein. The SPI is Switzerland's most closely followed performance index. It is used as a benchmark for mutual funds, index funds and ETFs, and as an underlying index for derivative financial instruments such as options, futures and structured products. In 2020, the SPI, along with other SIX indices, was endorsed under the EU Benchmarks Regulation and is registered with the European Securities and Markets Authority, which means that it can be used as an underlying for financial products sold in the EU. SPI Universe The underlying share universe of the SPI is the Swiss All Share Index and includes approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Π-calculus
In theoretical computer science, the -calculus (or pi-calculus) is a process calculus. The -calculus allows channel names to be communicated along the channels themselves, and in this way it is able to describe concurrent computations whose network configuration may change during the computation. The -calculus has few terms and is a small, yet expressive language (see ). Functional programs can be encoded into the -calculus, and the encoding emphasises the dialogue nature of computation, drawing connections with game semantics. Extensions of the -calculus, such as the spi calculus and applied , have been successful in reasoning about cryptographic protocols. Beside the original use in describing concurrent systems, the -calculus has also been used to reason about business processesOMG Specification (2011)"Business Process Model and Notation (BPMN) Version 2.0" ''Object Management Group''. p.21 and molecular biology. Informal definition The -calculus belongs to the family of proc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sediment Profile Imagery
Sediment Profile Imagery (SPI) is an underwater technique for photographing the interface between the seabed and the overlying water. The technique is used to measure or estimate biological, chemical, and physical processes occurring in the first few centimetres of sediment, pore water, and the important benthic boundary layer of water. Time-lapse imaging (tSPI) is used to examine biological activity over natural cycles, like tides and daylight or anthropogenic variables like feeding loads in aquaculture. SPI systems cost between tens and hundreds of thousands of dollars and weigh between 20 and 400 kilograms. Traditional SPI units can be effectively used to explore continental shelf and abyssal depths. Recently developeSPI-Scanor rSPI (rotational SPI) systems can now also be used to inexpensively investigate shallow (300 mV (oxidation reduction potential) level for oxic and less than 100 mV for anoxic chemoclines (with suboxic in between) as presented in Figure 3.

Abraham Lincoln Capital Airport
Abraham Lincoln Capital Airport is a civil-military airport in Sangamon County, Illinois, United States, three miles (6 km) northwest of downtown Springfield. It is owned by the Springfield Airport Authority (SAA). The airport is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2019–2023, in which it is categorized as a non-hub primary commercial service facility. It is the seventh busiest airport of the 12 commercial airports in Illinois. History The airport has dedicated in November 1947 under the name "Capital Airport." It came after pressure to construct a modern facility, as American Airlines and Chicago & Southern Airlines had canceled flight to Springfield a year earlier due to inadequate facilities at Capital Airport's predecessor. Construction on the new airport was began soon after those cancellations but were delayed due to World War II. The original airport had three 5300-foot runways, a service apron, ...

Social Progress Index
The Social Progress Index (SPI) measures the extent to which countries provide for the social and environmental needs of their citizens. Fifty-four indicators in the areas of basic human needs, foundations of well-being, and opportunity to progress show the relative performance of nations. The index is published by the nonprofit Social Progress Imperative, and is based on the writings of Amartya Sen, Douglass North, and Joseph Stiglitz. The SPI measures the well-being of a society by observing social and environmental outcomes directly rather than the economic factors. The social and environmental factors include wellness (including health, shelter and sanitation), equality, inclusion, sustainability and personal freedom and safety. Introduction and methodology The index combines three dimensions # Basic human needs # Foundations of well-being # Opportunity Each dimension includes four components, which are each composed of between three and five specific outcome indicators.

Single-point Injection
Manifold injection is a mixture formation system for internal combustion engines with external mixture formation. It is commonly used in engines with spark ignition that use petrol as fuel, such as the Otto engine, and the Wankel engine. In a manifold-injected engine, the fuel is injected into the intake manifold, where it begins forming a combustible air-fuel mixture with the air. As soon as the intake valve opens, the piston starts sucking in the still forming mixture. Usually, this mixture is relatively homogeneous, and, at least in production engines for passenger cars, approximately stoichiometric; this means that there is an even distribution of fuel and air across the combustion chamber, and enough, but not more air present than what is required for the fuel's complete combustion. The injection timing and measuring of the fuel amount can be controlled either mechanically (by a fuel distributor), or electronically (by an engine control unit). Since the 1970s and 1980s, manifol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stateful Firewall
In computing, a stateful firewall is a network-based firewall that individually tracks sessions of network connections traversing it. Stateful packet inspection, also referred to as dynamic packet filtering, is a security feature often used in non-commercial and business networks. Description A stateful firewall keeps track of the state of network connections, such as TCP streams, UDP datagrams, and ICMP messages, and can apply labels such as ''LISTEN'', ''ESTABLISHED'', or ''CLOSING''. State table entries are created for TCP streams or UDP datagrams that are allowed to communicate through the firewall in accordance with the configured security policy. Once in the table, all ''RELATED'' packets of a stored session are streamlined allowed, taking fewer CPU cycles than standard inspection. Related packets are also permitted to return through the firewall even if no rule is configured to allow communications from that host. If no traffic is seen for a specified time (implement ...

System Packet Interface
The System Packet Interface (SPI) family of Interoperability Agreements from the Optical Internetworking Forum specify chip-to-chip, channelized, packet interfaces commonly used in synchronous optical networking and Ethernet applications. A typical application of such a packet level interface is between a framer (for optical network) or a MAC (for IP network) and a network processor. Another application of this interface might be between a packet processor ASIC and a traffic manager device. Context There are two broad categories of chip-to-chip interfaces. The first, exemplified by PCI-Express and HyperTransport, supports reads and writes of memory addresses. The second broad category carries user packets over 1 or more channels and is exemplified by the IEEE 802.3 family of Media Independent Interfaces and the Optical Internetworking Forum family of System Packet Interfaces. Of these last two, the family of System Packet Interfaces is optimized to carry user packets from man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
