Aomori (city)

Aomori is the capital city of Aomori Prefecture, in the Tōhoku region of Japan. As of 1 June 2019, the city had an estimated population of 276,567 in 136,209 households, a population density of 335 people per square kilometer spread over the city's total area of 824.61 square kilometers. Aomori is one of Japan's 48 core cities. Aomori is located in central Aomori Prefecture, on a plain between the southern end of Aomori Bay, which it faces to the north and the Hakkōda Mountains to the south. Among other smaller rivers, the city has two large rivers flowing through it, the Komagome River and its tributary, the Arakawa River. Aomori Prefecture Kuroishi, Towada, Hirakawa Kitatsugaru DistrictItayanagi Minamitsugaru District – Fujisaki Higashitsugaru DistrictHiranai, Yomogita Kamikita DistrictShichinohe Like most of Tōhoku, Aomori has a humid temperate climate with hot summers, cold, though not extreme, winters; the city has a humid continental climate. Aomori and its surrounding area are renowned for heavy snowfall, the heaviest among all Japanese cities, and, in fact, among the heaviest in the world.

In February 1945 the city recorded a maximum snow cover of 209 centimetres, but the extreme low of −24.7 °C was recorded 14 years earlier. In contrast, Sapporo's heaviest snowfall occurred in 1939, and, only 164 centimetres, more northerly Wakkanai has recorded similar maxima; the heavy snow is caused by several winds that collide around the city and make the air rise and cool, resulting in quick, thick cloud formation followed by intense precipitation. In summer, a cool wind called "Yamase" blows from the east, which sometimes results in abnormally cool weather and poor harvests. Additionally, thick fogs from the Oyashio Current are observed in mountainous areas in the summer. Due to this fog, flights to Aomori Airport are cancelled. Per Japanese census data, the population of Aomori has remained steady over the past 40 years. Aomori means blue forest, although it could be translated as "green forest"; the name is considered to refer to a small forest on a hill which existed near the town. This forest was used by fishermen as a landmark.

A different theory suggests. The area has been settled extensively since prehistoric times, numerous Jōmon period sites have been found by archaeologists, the most famous being the Sannai-Maruyama site located just southwest of the city center dating to 5500-4000 BC, the Komakino Site farther south dating to around 4000 BC; the large scale of these settlements revolutionized theories on Jōmon period civilization. During the Heian period, the area was part of the holdings of the Northern Fujiwara clan, but remained inhabited by the Emishi people well into the historic period. After the fall of the Northern Fujiwara in the Kamakura period, the territory was part of the domain assigned to the Nambu clan, into the Sengoku period, it came under the control of the rival Tsugaru clan, whose main castle was located in Namioka. After the start of the Edo period, what would become the core of present-day Aomori was a minor port settlement in the Hirosaki Domain called Utō; the town was rebuilt in 1626 under orders of the daimyō, Tsugaru Nobuhira and renamed "Aomori", but this name did not come into common use until after 1783.

Some evidence claims that Aomori and Utō co-existed in different parts the city in its current state. It wasn't until 1909. After the Meiji Restoration, the feudal domains were abolished and replaced with prefectures, of which a total of six were created in the territory of modern Aomori Prefecture; these were merged into the short-lived Hirosaki Prefecture in July 1871. However, due to the historic enmity between the former Tsugaru territories in the west and the former Nambu territories in the east, the prefectural capital was relocated from Hirosaki to the more centrally-located Aomori after the merger and the prefecture was renamed Aomori Prefecture on 23 September 1871. However, the municipality of Aomori was not given town status within Higashitsugaru District until 1 April 1889, it was designated as a city on 1 April 1898. The Hokkaidō Colonization Office began operations of a ferry service from Aomori to Hakodate in Hokkaido from 1872. In September 1891, Aomori was connected with Tokyo by rail with the opening of the Tōhoku Main Line.

The Ōu Main Line running along the Sea of Japan coast opened in December 1894. The development of modern Aomori was due to its prefectural capital status and the singular importance as the terminus of these rail lines and the Seikan Ferry, which opened in 1908; the 8th Division of the Imperial Japanese Army were stationed in Aomori from 1896. In the winter of 1902, 199 of 210 soldiers on a military cold-weather readiness exercise perished while attempting to cross the Hakkōda Mountains from Aomori to Towada in what was called the Hakkōda Mountains incident. Much of the town burned down in a large fire on 3 May 1910; the port facilities were expanded in 1924, the city received its first bus services in 1926. Japan Air Transport began scheduled air services from 1937. Towards the final stages of World War II, on the night of 28-29 July 1945, Aomori was subject to an air raid as part of the strategic bombing campaign waged by the United States of America against military and civilian targets and population centers during the Japan home isla

USS Trippe (DD-33)

The second USS Trippe was a Paulding-class destroyer in the United States Navy during World War I and in the United States Coast Guard, designated. She was named for Lieutenant John Trippe. Trippe was laid down on 12 April 1910 at Maine, by the Bath Iron Works. Upon commissioning, Trippe joined the torpedo boat destroyers and submarines assigned to the east coast as a unit of the Atlantic Torpedo Fleet. For the next three years, she conducted routine operations along the east coast. In 1911, she completed trials and participated in exercises off Newport and the Virginia Capes, she made her first cruise to southern waters in 1912. She dropped anchor in Guantanamo Bay 11 days later. Following three months of training at Guantanamo Bay and in the Gulf of Mexico, the torpedo boat destroyer returned north in April and entered Boston harbor on the 21st. After repairs, Trippe resumed training operations off the northeastern coast. On 2 January 1913, the warship headed south once more for three months of tactical exercises and gunnery drills out of Guantanamo Bay and in the Gulf of Guacanayabo.

She returned to Boston on 14 April and spent the remainder of 1913 in operations off the coast between Boston and Norfolk, Virginia. Trippe began 1914 as she had the previous two years — by heading south and conducting battle practice in the Caribbean through the end of March. However, in April, the Tampico incident brought her to the shores of Mexico, when American sailors and Marines went ashore at Veracruz and seized the customs house on the 21st. Trippe arrived off Tampico on the 22d and patrolled the area for a week to prevent arms from being landed. On 1 May, she steamed south to Vera Cruz where she conducted more patrols and supported the battleships and cruisers operating in the vicinity. Near the end of the month, Trippe cleared Mexican waters. At the completion of an extensive overhaul, the warship conducted trials and drills in the Boston area from mid-August to late September. On 30 September, Trippe arrived at Newport for a week of operation before heading south, she shifted to Hampton Roads in mid-October and participated in exercises there and at Lynnhaven Bay for a month before returning to Boston.

The warship spent December and the first three weeks of 1915 in the Boston area and, on 26 January, arrived in Guantanamo Bay to resume her schedule of winter drills in the Caribbean. Late in March, Trippe reached Boston on 6 April. After her normal round of maneuvers off the northeastern coast, the torpedo boat destroyer returned to Boston on 23 October. A little less than two months — on 13 December 1915 — Trippe became a unit of the newly organized 2nd Reserve Flotilla. On 5 January 1916, she was designated a "Destroyer operating with reduced complement; the threat of war, made her retirement a brief one. Trippe was placed in full commission once again at Boston on 25 July 1916, junior grade Roy P. Emrich in command. During the following eight months, Trippe trained along the coast in preparation for the probable entry of the United States into World War I; the United States declared war on the German Empire on 6 April 1917. Trippe continued to operate off the coast until early May, when she entered Boston and commenced preparations for duty overseas.

On 21 May, the destroyer cleared Boston for Britain. After a call at St. John's, she arrived in Queenstown on the southern coast of Ireland, the location of a major wartime American destroyer base, she paused only long enough to refuel and make voyage repairs before clearing the harbor on 5 June for her first patrol. From Queenstown, she escorted Allied convoys on the last leg of their voyage from America to France and England, her field of operations, situated as it was in the war zone, established around the British Isles by Germany on 5 February 1915, was the prime hunting ground of High Seas Fleet U-boats. When not engaged in escorting convoys, Trippe patrolled the waters around Queenstown in an effort to detect and destroy as many enemy submarines as possible; the warship had only one verified scrape with German U-boats. On 18 September 1917, she and Jacob Jones were steaming in company some 350 mi west of Brest, when — shortly after 0200 — she sighted the distinctive wake of the periscope of a submarine running on a parallel course, but in the opposite direction.

Trippe dropped depth charges, but without "visible results", continued on to rendezvous with an eastbound convoy. That night, she dueled with another adversary — the sea. In a raging storm, waves carried her starboard waist gun platform overboard. Trippe, however shepherded her convoy into Quiberon Bay, made repairs and resumed her grueling routine. Through the final year of the war and her sister ships bested the enemy. Convoys of merchant ships carried troops and supplies to France, where the armies of the Allies grew steadily. By the fall of 1918, they reached a point of overwhelming superiority over those of the Central Powers. On 11 November, the day of the signing of Trippe was in port at Queenstown. Just over a month she cleared that Irish port, refueled at the Azores and Bermuda, returned to Boston on 3 January 1919. After six months of operations along the eastern seaboard, the destroyer entered the Philadelphia Navy Yard on 23 July for preinactivation overhaul. On 6 November 1919, Trippe was decommissioned and placed in reserve at Philad


The ROMP is a reduced instruction set computer microprocessor designed by IBM in the late 1970s. It is known as the Research OPD Microprocessor and 032; the ROMP was developed for office equipment and small computers, intended as a follow-on to the mid-1970s IBM OPD Mini Processor microprocessor, used in the IBM Office System/6 word-processing system. The first examples became available in 1981, it was first used commercially in the IBM RT PC announced in January 1986. For a time, the RT PC was planned to be a personal computer, with ROMP replacing the Intel 8088 found in the IBM Personal Computer. However, the RT PC was re-positioned as an engineering and scientific workstation computer. A CMOS version of the ROMP was first used in the coprocessor board for the IBM 6152 Academic System introduced in 1988, it appeared in some models of the RT PC; the architectural work on the ROMP started in late spring of 1977, as a spin-off of IBM Research's 801 RISC processor. Most of the architectural changes were for cost reduction, such as adding 16-bit instructions for byte-efficiency.

The original ROMP had a 24-bit architecture, but the instruction set was changed to 32 bits a few years into the development. The first chips were ready in early 1981, making ROMP the first industrial RISC; the processor was revealed at the International Solid-State Circuits Conference in 1984 ROMP first appeared in a commercial product as the processor for the IBM RT PC workstation, introduced in 1986. To provide examples for RT PC production, volume production of the ROMP and its MMU began in 1985; the delay between the completion of the ROMP design, introduction of the RT PC was caused by overly ambitious software plans for the RT PC and its operating system. This OS could host multiple other operating systems; this technology, called virtualization, while commonplace in mainframe systems, only began to gain traction in smaller systems in the 21st century. An improved CMOS version of the ROMP was first used in the IBM 6152 Academic System workstation, in some models of the RT PC. IBM Research used the ROMP in its Research Parallel Processor Prototype, an early experimental scalable shared-memory multiprocessor that supported up to 512 processors first detailed in 1985.

The ROMP's architecture was based on the original version of the IBM Research 801 minicomputer. The main differences were a larger word size, the inclusion of virtual memory; the architecture supported 8-, 16-, 32-bit integers, 32-bit addressing, a 40-bit virtual address space. It had sixteen 32-bit general-purpose registers; the microprocessor was controlled by 32-bit instructions. The ROMP's virtual memory has a segmented 40-bit address space consisting of 4,096 256 MB segments; the 40-bit virtual address is formed in the MMU by concatenating a 12-bit segment identifier with 28 low-order bits from a 32-bit ROMP-computed virtual address. The segment identifier is obtained from a set of 16 segment identifiers stored in the MMU, addressed by the four high-order bits of the 32-bit ROMP-computed virtual address; the ROMP is a scalar processor with a three-stage pipeline. In the first stage, if there are instructions in the 16-byte instruction prefetch buffer, an instruction was fetched and operands from the general-purpose register file read.

The instruction prefetch buffer read a 32-bit word from the memory whenever the ROMP was not accessing it. Instructions were executed in the second stage, written back into the general-purpose register file in the third stage; the ROMP used a bypass network and appropriate scheduled the register file reads and writes to support back-to-back execution of dependent instructions. Most register-to-register instructions were executed in a single cycle; the ROMP had an IBM-developed companion integrated circuit, code-named Rosetta during development. Rosetta was a memory management unit, it provided the ROMP with address translation facilities, a translation lookaside buffer, a store buffer; the ROMP and Rosetta were implemented in an IBM 2 μm silicon-gate NMOS technology with two levels of metal interconnect. The ROMP consists of 45,000 transistors and is 7.65 × 7.65 mm large, while Rosetta consists of 61,500 transistors and is 9.02 × 9.02 mm large. Both are packaged in 135-pin ceramic pin grid arrays.

A CMOS version of the ROMP and Rosetta was developed. The IBM RT PC ROMP processor and memory management unit architecture

Truncation error (numerical integration)

Truncation errors in numerical integration are of two kinds: local truncation errors – the error caused by one iteration, global truncation errors – the cumulative error caused by many iterations. Suppose we have a continuous differential equation y ′ = f, y = y 0, t ≥ t 0 and we wish to compute an approximation y n of the true solution y at discrete time steps t 1, t 2, …, t N. For simplicity, assume the time steps are spaced: h = t n − t n − 1, n = 1, 2, …, N. Suppose we compute the sequence y n with a one-step method of the form y n = y n − 1 + h A; the function A is called the increment function, can be interpreted as an estimate of the slope y − y h. The local truncation error τ n is the error that our increment function, A, causes during a single iteration, assuming perfect knowledge of the true solution at the previous iteration. More formally, the local truncation error, τ n, at step n is computed from the difference between the left- and the right-hand side of the equation for the increment y n ≈ y n − 1 + h A: τ n = y − y − h A.

The numerical method is consistent if the local truncation error is o. If the increment function A is continuous the method is consistent if, only if, A = f. Furthermore, we say that the numerical method has order p if for any sufficiently smooth solution of the initial value problem, the local truncation error is O; the global truncation error is the accumulation of the local truncation error over all of the iterations, assuming perfect knowledge of the true solution at the initial time step. More formally, the global truncation error, e n, at time t n is defined by: e n = y − y n = y − ( y 0 + h
