Indian Airlines Flight 171. Indian Airlines Flight 171 was a Caravelle that crashed while attempting an emergency landing at Bombay Airport (now Chhatrapati Shivaji Maharaj International Airport) on 12 October 1976 after suffering an uncontained engine failure, killing all 95 people on board. Metal fatigue in the No. 2 engine's 10th stage high-pressure compressor disk had caused it to disintegrate, the resulting fragments severed fuel lines causing fuel to leak into the engine and ignite causing an uncontrolled fire that eventually affected control surfaces leading to a loss of control.

Accident
Flight 171 was a scheduled domestic passenger flight from Bombay (now Mumbai) to Madras (now Chennai). A Boeing aircraft was originally supposed to make the flight but it developed engine trouble and was replaced with a Sud Aviation Caravelle. Shortly after takeoff from runway 27, Flight 171 suffered a No. 2 engine failure. The crew of Flight 171 immediately turned back to attempt an emergency landing on Bombay Airport's runway 09. With its undercarriage down approximately  from the end of the runway and while at an altitude of , the aircraft suffered a loss of control and plummeted into the ground. Everyone on board Flight 171 perished in the accident.

Cause
A fatigue crack in the tenth stage compressor disc caused a power plant failure which was followed by the bursting of the compressor casing and the cutting of fuel lines that spanned the structure. This caused an intense in-flight fire in the engine bay. It is believed the fire consumed the Caravelle's supply of hydraulic fluid and this was the cause of the aircraft going out of control.

Passengers
Indian actress Rani Chandra died in the accident while actor Jeetendra had planned to board the airliner but cancelled. The actor said that because it was Karwa Chauth, his wife asked him to delay his trip, but Jeetendra decided to head to the airport anyway. After reaching the airport, he realised that the flight was late and decided to go back home to help his wife break her fast. Subsequently, his wife did not allow him to return to the airport, and hours later he read that the plane had burst into flames mid-air.

John Torrence Tate Sr.. John Torrence Tate Sr. (July 28, 1889 – May 27, 1950) was an American physicist noted for his editorship of Physical Review between 1926 and 1950. He is the father of mathematician John Torrence Tate Jr.

Biography
Tate was born on July 28, 1889, in Lenox, Iowa. He attended the University of Nebraska, studying electrical engineering, earning a BS in 1910. He continued at the University of Nebraska, shifting his focus to physics and earning an MA in 1912. He departed for Germany to further his studies, earning a PhD under James Franck in 1914, with a dissertation on "The Heat of Vaporization of Metals". He returned to the University of Nebraska as a faculty member, where he stayed until 1916, when he was offered a post at the University of Minnesota. With the exception of brief sabbaticals to conduct war-related work, Tate remained at Minnesota for the following 34 years. Tate Laboratory of Physics at the University of Minnesota is named in his honor.

Editor of Physical Review
While a professor at the University of Minnesota, Tate presided over the growth of the Physical Review into a high impact journal. Physicist John H. Van Vleck, who was a colleague of Tate's at Minnesota from 1923 to 1928, recalled that in the early 20th century "The Physical Review was only so-so, especially in theory, and in 1922 I was greatly pleased that my doctor's thesis was accepted for publication by the Philosophical Magazine in England . . . By 1930 or so, the relative standings of The Physical Review and Philosophical Magazine were interchanged." Alfred Nier and John Van Vleck credited the rapid growth of the journal's size and influence in the 1920s to Tate's sensitivity to the importance of the emerging quantum revolution, and in particular the rapidity with which he published papers relating to quantum phenomena.

Reviewing Einstein and Rosen
On June 1, 1936, Tate, as the editor of the Physical Review, received a submission from Albert Einstein and Nathan Rosen. Tate sent the submission to H.P. Robertson, who made an anonymous critical peer review questioning the basic conclusion of the paper. On July 23, Tate returned the submission with the anonymous review. On July 27, Einstein replied:

Thin walled beams. A thin walled beam is a type of beam (structure) that does not have a solid cross sectional area. The cross section of thin walled beams is made up from thin panels connected together. Typical closed sections include round, square, and rectangular tubes. Open sections include I-beams, T-beams, L-beams, and so on. The advantages of thin walled beams are their lighter weight and their bending stiffness per unit cross sectional area, which is much higher than for solid cross sections such as a rod or bar. Thin-walled beams are found almost everywhere, in civil and naval engineering, as well as aeronautics and aerospace designs. Apart from lightweight construction, strong rigidity, and load resistance, there are also lower manufacturing costs, and lower transport and maintenance costs. They also give the designer more flexibility in the choice of material and shape to meet any specific requirements. Thin walled beams are particularly useful when the material is a composite laminate.  Pioneer work in this regard was done by Librescu.

Transfer switcher. A transfer switcher was a type of railroad locomotive specifically designed to perform "transfer" work in which freight cars are transported between two freight yards in a large terminal area.

Design
As transfer work required high pulling power but not much speed, the general design of a transfer locomotive consisted of two engines with high-horsepower on an elongated locomotive frame, gearing designed for low speeds, and several driving axles, but were generally built without dynamic braking or multiple unit capability. In addition to the "center cab" design, transfer locomotives were also built in the form of road switchers and drawbar-coupled cow and calf switcher sets.

Center cab
The "center cab" configuration is probably the best remembered transfer locomotive design, as the majority of these locomotives were built for transfer work. The first of the "center cab" locomotives was simply designated the T, and was a one-of-a-kind locomotive, built as a collaboration by the Electro Motive Corporation, St. Louis Car Company and General Electric for the Illinois Central Railroad in 1936.

Production
Baldwin Locomotive Works and Lima-Hamilton (which would later merge to become Baldwin-Lima-Hamilton) produced the majority of these units, with the former producing 70 Baldwin DT-6-6-2000/BLH RT-624 locomotives, and the latter producing 22 Lima A-3177  locomotives between 1946 and 1954.

Preservation
Only one surviving example of these locomotives is known to exist. Minneapolis, Northfield and Southern Railroad DT-6-6-2000 #21 is preserved at the Illinois Railway Museum in Union, Illinois.

History
Organized as "Detachment 1", 3201st Air Base Support Squadron, on 26 April 1950, taking over mission of 2d Guided Missiles Squadron (GMS), 550th Guided Missiles Wing. Operated QB/DB-17 Flying Fortress drone/director aircraft drones as flying targets for the early Army Nike Ajax surface-to-air missile or for the Hughes Falcon air-to-air missiles being tested at White Sands Missile Range.   Also supplied aerial targets as needed by the Air Force Missile Development Center.

Upgraded to squadron level in 1953.  Began operating BQM-34A Firebee Drones in 1957 to provide remote-controlled target aircraft for  Center. The squadron would also support test projects and provide land recovery for target drones.
A notable moment in the squadron's history is that a Douglas/Long Beach DB-17P (Formerly B-17G-90-DL) 44-83684 flew the last operational mission by a USAF Flying Fortress on 6 August 1959.

Began operating Ryan Q2-C, the improved version of the first Firebee in 1960. It had more powerful engines, could climb faster and higher.  Formally transferred to the Missile Development Center in 1961, operated Firebee drones and assisted in its development.   Inactivated 1963 when program consolidated with  Air Defense Command at Tyndall AFB, Florida.

History
Organized as "Detachment 2", 3201st Air Base Support Squadron, on 26 April 1950,  Mission was to maintain and operate provide services and material to support operations of  aviation activities and units.  Operated QB/DB-17 Flying Fortress drone/director aircraft drones as flying targets for the Naval Point Mugu developmental and evaluation tests.

The unmanned B-17 drones were guided by pilots flying in mothership B-17s and the drone aircraft were used as target practice by fighter jets using missiles. Since the missiles they used were without warheads the drones, when hit, were guided back to the ground. They were then repaired and reused for other missions, including ground to air attacks.

Inactivated in 1957 with the end of the B-17 target drone program.

USCGC Point Hannon. USCGC Point Hannon (WPB-82355) was an  Point class cutter constructed in 1967 for use as a law enforcement and search and rescue patrol boat.

Design and construction details

Construction and design details
Point Hannon was built to accommodate an 8-man crew. She was powered by two  VT600 Cummins diesel main drive engines and had two five-bladed  propellers. The main drive engines were later replaced by  VT800 Cummins engines. Water tank capacity was  and fuel capacity was  at 95% full. Engine exhaust was ported through the transom rather than through a conventional stack permitting a 360 degree view from the bridge a useful feature in search and rescue work.

She had a steel hull, an aluminum superstructure with a longitudinally framed construction to save weight. Controls were located on the bridge which allowed one-man operation and eliminated an engineer watch in the engine room. For short periods, a crew of four men could operate the cutter, however, the need for rest brought the practical crew to eight for normal service. The screws were designed for ease of replacement and could be changed without removing the cutter from the water. A clutch-in idle speed of three knots helped to conserve fuel on lengthy patrols and she had an eighteen knot maximum speed.

Interior access was through a watertight door on the starboard side aft of the deckhouse, which contained the cabin for the officer-in-charge and the executive officer,  a small arms locker, scuttlebutt, desk and head. Access to the lower deck and engine room was via a ladder, at the bottom of which was the galley, mess and recreation deck. A watertight door at the front of the mess bulkhead led to the crew quarters which was ten feet long with six stowable bunks, three on each side. Forward of the bunks was the crew's head with sink, shower and commode, interior spaces were air-conditioned.

History
Point Hannon was stationed at West Jonesport, Maine from 1967 to January 
2001. She was used for law enforcement and search and rescue operations. On 12 July 1967, while towing F/V Stanley Butler, the tow was hit by F/V Hope II in Great Round Shoals Canal. The cutter commenced a tandem tow until relieved by cutter Cape Horn. On 22 October 1967, she helped fight fire on the Indian M/V Vishva Mangal near Searsport, Maine. On 13 December 1978, she seized the Panamanian tug Tuskewr, which was attempting to smuggle hashish worth about $1 million into the U.S. On 15 January 1984, she rescued a man clinging to a buoy 12 miles off Rockland, Maine.

Point Hannon was transferred to the Naval Force of Panama in 2001 and renamed P-209 5 de Noviembre Since then the ship has played in various missions along the territorial waters of the Republic of Panama as part of the naval fleet, under the aegis of the National Directorate of Operations, Naval Group. Panama has 5 ships of this type.

Oracle Retail Predictive Application Server. The Oracle Retail Predictive Application Server (commonly referred to as RPAS) is a configurable software platform for developing forecasting and planning applications, following a Client/Server OLAP model. The RPAS platform provides capabilities such as a multidimensional database structure (it follows the  MOLAP model but has some ROLAP capabilities), batch and online processing, a configurable slice-and-dice user interface, a sophisticated configurable calculation engine, user security and utility functions such as importing and exporting.

RPAS is the foundation for a significant number of applications that are part of the Oracle Retail solution footprint, such as Oracle Retail Demand Forecasting, Oracle Merchandise Financial Planning, Oracle Assortment Planning, Oracle Item Planning, Oracle Size Profile Optimization, Oracle Replenishment Optimization and Oracle Advanced Inventory Planning.  The latest version is Version 16 released in December 2016, and supports deployment of planning applications on-premise or Software as a service over the internet.

RPAS currently offers 2 data persistence options: a proprietary datastore based on Oracle Berkeley DB, or an Oracle RDBMS (which supports real time updates from external systems but reduces the performance of the MOLAP cubes).  Originally the persistence layer (and some of the processing) was based on a MOLAP engine called Acumate/Acumen, originally developed by Mars Inc. for in house reporting and analysis;  the software was sold by Mars and went through several owners, ultimately being owned by Lucent via an acquisition of a previous owner.  Acumate is now no longer generally available or in support from Lucent. (Limited sustaining support for Acumate is available from Oracle to support the few remaining older installations of RPAS that were Acumate based, based on a source code license that was held by the predecessor to Oracle Retail, Retek, with the source code license novated to Oracle for support purposes).
