Convergence Tests
In mathematics, convergence tests are methods of testing for the convergence, conditional convergence, absolute convergence, interval of convergence or divergence of an infinite series \sum_^\infty a_n. List of tests Limit of the summand If the limit of the summand is undefined or nonzero, that is \lim_a_n \ne 0, then the series must diverge. In this sense, the partial sums are Cauchy only if this limit exists and is equal to zero. The test is inconclusive if the limit of the summand is zero. This is also known as the nth-term test, test for divergence, or the divergence test. Ratio test This is also known as d'Alembert's criterion. : Consider two limits \ell=\liminf_\left, \frac\ and L=\limsup_\left, \frac\. If \ell>1, the series diverges. If L 1. The case of p = 1, k = 1 yields the harmonic series, which diverges. The case of p = 2, k = 1 is the Basel problem and the series converges to \frac. In general, for p > 1, k = 1, the series is equal to the Riemann zeta funct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huawei P Series
The Huawei Pura (formerly the Ascend P series and P series) is a series of high-end and medium-range smartphones produced by Huawei, based on its proprietary HarmonyOS mobile operating system ( Android-based prior to US sanctions and trade war in 2019). The P series was formerly marketed as part of Huawei's larger Ascend brand, and some models were called ''P smart''. Under the company's current hardware release cadence, Pura series phones are typically directed towards mainstream consumers as the company's flagship smartphones, refining and expanding upon technologies introduced in Mate series phablet devices (which are typically positioned towards early adopters). The Pura series has featured a strong emphasis on camera functionality; since 2016, and beginning with the Huawei P9, Huawei has been in a co-engineering partnership with the German optics manufacturer Leica. On April 15, 2024, Huawei rebranded its P series as the "Pura series", starting with the Pura 70. Phone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruger P Series
The Ruger P series is a line of centerfire semi-automatic pistols made by Sturm, Ruger & Company produced from 1985 to 2013. The P-series pistols were designed for military, police, civilian and recreational use. The designs are largely based on the John Browning, Browning action found in the M1911 pistol, but with minor variations, generally related to the safety mechanism and the barrel-camblock interface. Reviews have considered them rugged, reliable, and strong, though this strength comes at the price of bulk and a blocky appearance.Glenn Barnes"Ruger's P series: what's wrong with Ruger's P-series semiauto pistols? Not a darn thing, says the author" ''Guns Magazine''. FindArticles.com. Retrieved 2009-11-03. Design details The P-series pistols are Recoil operation#Short recoil operation, short recoil–operated, locked breech semi-automatic pistols. They use a SIG P220 type locking system, and an M1911-style tilting barrel. The P series were made with a traditional trigger (fir ...

Cyber-shot
Cyber-shot is Sony's line of point-and-shoot digital cameras introduced in 1996. Cyber-shot model names use a DSC prefix, which is an initialism for "Digital Still Camera". Many Cyber-shot models feature Carl Zeiss trademarked lenses, while others use Sony, or Sony G lenses. All Cyber-shot cameras accept Sony's proprietary Memory Stick or Memory Stick PRO Duo flash memory, except the DSC-MD1 which only accept MiniDisc. Select models have also supported CompactFlash. Current Cyber-shot cameras support Memory Stick PRO Duo, SD, SDHC, and SDXC. From 2006 to 2009, Sony Ericsson used the Cyber-shot brand in a line of mobile phones. Models The current lineup consists of: * R and RX series – state-of-the-art, large-sensor compact cameras ** DSC-RX100/DSC-RX100 II/III/IV/V/VI/VII – pocketable camera with the largest 1" sensor of all cameras of its size ** DSC-RX10/DSC-RX10 II — zoom lens 1" 24-200mm equivalent 35 mm bridge camera with constant widest aperture F2.8 ** ...

Sony Ericsson P Series
The following is a list of products manufactured under the Sony Ericsson brand. Most of the models have been released under multiple names, depending on region of release, currently usually indicated by a letter added to the end of the model number ('i' for international, 'a' for North America, and 'c' for mainland China), but indicated on some (mostly older) models by a slightly differing model number. Typically, there is one version for the European and US market, and another for the Asian market. However, some models have yet more versions. Most "Walkman" branded models are also released as a non-Walkman version; such as Sony Ericsson W580 and the S500. These versions usually differ only slightly. International phones Each phone in boldface indicates that the phone is a smartphone. S = Status, where P indicates ''under production'', D is ''discontinued'' and U indicates ''upcoming'' .

Vespa
Vespa () is an Italian brand of scooters and mopeds manufactured by Piaggio. The name means wasp in Italian. The Vespa has evolved from a single model motor scooter manufactured in 1946 by Piaggio & Co. S.p.A. of Pontedera, Italy, to a full line of scooters and one of seven companies today owned by Piaggio. From their inception, Vespa scooters have been known for a painted, pressed steel body which combines, in a unified structure: a full cowling enclosure around the engine concealing dirt or grease, a flat floor panel protecting the feet, and a prominent front fairing to divert wind and rain. History After World War II, in light of its agreement to cease war activities with the Allies, Italy had its aircraft industry severely restricted in both capability and capacity. Piaggio emerged from the conflict with its Pontedera bomber plane plant demolished by bombing. Italy's crippled economy, and the disastrous state of its roads, were not immediately conducive to the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM PSeries
The IBM System p is a high-end line of Reduced instruction set computer, RISC (IBM Power microprocessors, Power)/Unix, UNIX-based servers. It was the successor of the RS/6000 line, and predecessor of the IBM Power Systems server series. History The previous RS/6000 line was originally a line of workstations and servers. The first System p server line was named the ''e''Server pSeries in 2000 as part of the e-Server branding initiative. In 2004, with the advent of the POWER5 processor, the server family was rebranded the ''e''Server p5. In 2005, following IBM's move to streamline its server and storage brands worldwide, and incorporating the "System" brand with the Systems Agenda, the family was again renamed to System p5. The System p5 now encompassed the IBM OpenPower product line. In 2007, after the introduction of the POWER6 processor models, the last rename under the System p brand dropped the p (numbered) designation. In April 2008, IBM announced a rebranding of the Syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ThinkPad P Series
The ThinkPad P series line of workstation laptop computers produced by Lenovo as part of the ThinkPad product family.
