Delta N. The Delta N or Thor-Delta N was an American expendable launch system used for nine orbital launches between 1968 and 1972. It was a member of the Delta family of rockets, and the last Delta to be given an alphabetical designation - subsequent rockets were designated using a four digit numerical code.

The Delta N consisted of two stages. The first stage was the Long Tank Thor, a stretched version of the Thor missile, previously flown on the Delta L and Delta M. Three Castor-2 solid rocket boosters were attached to increase thrust at lift-off. A Delta E was used as the second stage. If an increased payload capacity was required, six boosters were flown instead of three, in a configuration known as the Delta N6, or "Super Six". Three launches used the N6 configuration.

Delta N rockets were launched from Launch Complex 17A at the Cape Canaveral Air Force Station, and SLC-2 at Vandenberg AFB. There was one failure, the launch of ITOS E on October 21, 1971. The Delta second stage developed an oxidizer leak about 40 seconds into launch so that when its burn began, the engine quickly lost thrust. In addition, the leaking LOX started pushing the stage off its proper flight path. The guidance system tried to compensate by repeatedly firing the attitude control jets, but this resulted in the rapid exhaustion of their propellant and the launch vehicle started tumbling uncontrollably. The ITOS satellite separated on schedule, but was facing in the wrong direction for orbital insertion, so it simply reentered the atmosphere and burned up. The second stage itself and several pieces of debris did manage to reach orbit and remained there for several weeks.

Epoxy putty. Epoxy putty refers to a group of room-temperature-hardening substances used as space-filling adhesives. Exact compositions vary according to manufacturer and application. They are stored until used as two components of clay-like consistency. Kneading the two components into each other creates an exothermic chemical reaction that activates the substance for use by catalysing an epoxide polymerisation reaction.  Unlike many other types of glues, an epoxy adhesive can fill gaps, and even be moulded into a structural part. Some makers claim in advertising that one can drill and tap their cured products and that they quickly cure "hard as steel" (as measured by Shore rating), though they are much weaker than steel in tensile strength and shear strength.

Epoxy putty is often used by miniature modelers, and sculptors. Modelers use it to join disparate parts into a whole with the joins covered by moulded putty, often shaped into protrusions or textures to match their surroundings. The most common variety of epoxy putty used in modelling has its component clays coloured yellow and blue, respectively, and the mixed, hardened end product is green. This has given rise to the colloquial name green stuff for epoxy putty.

Lange Antares. The Lange Antares is a glider built by Lange Aviation produced with three different wingspans, 18, 20 and 23 meters.  The 20 and 23 meter variants can be equipped with a 42-kW electric motor and SAFT VL 41M lithium-ion batteries.

The EM 42 is a fixed-shaft brushless DC electric motor running at 190-288 V, and drawing up to 160 A, the 42 kW motor can deliver up to 216 N.m of torque over a speed range of 160-1600 RPM with a total efficiency of 90%. Maximum continuous power is 38.5 kW, the motor weighs 29 kg, and the weight of power electronics is 10 kg. The motor turns a two-blade fixed-pitch propeller, LF-P42, constructed of composite materials, having a diameter of two meters.

The battery system consists of two battery packs positioned in the leading edges of both inner wings (72 cells divided into 24 modules containing 3 cells each). The battery life is expected to be 3000 cycles or 20 years. The capacity of the battery is 41 Ah (specific energy 136 Wh/kg and specific peak power 794 W/kg). The batteries can deliver 13 minutes at maximum power and maximum climb speed, and can climb 3,000 meters on one battery charge; in reality, in warm climates, motor and electronics temperature limitations can limit the achievable climb height. The charger is integrated inside the fuselage so when landing elsewhere the pilot merely has to find a (16A) electric outlet socket. The glider has a modem connected to its main computer so that Lange technicians can, in theory, run diagnostics remotely. The same modem allows the pilot remote control & monitoring of the battery charging process.

The undercarriage and engine doors are electro-hydraulically operated. The tailwheel is steerable. The wing has an elliptical planform, with winglets and wing-tip wheels. The glide polar shows excellent high speed performance.

Variants

 Antares 18S - 18 meter wingspan pure glider.
 Antares 18T - 18 meter wingspan glider with Solo 2350 two-stroke gasoline sustainer engine.
 Antares 20E - 20 meter wingspan with 42 kW electric self-launch capable engine.

Jonas Hesselman. Jonas Hesselman (9 April 1877- 20 December 1957) was a Swedish engineer. He built the first spark ignition engine with direct injection of fuel into the cylinder.

Biography
Knut Jonas Elias Hesselman  was born at  Å församling in Östergötland, Sweden.
He was the son of factory owner Bror August Hesselman and Marie Louise Hesselman, née Åberg. He was the brother of professor Henrik Hesselman (1874–1943) and linguist Bengt Hesselman (1875–1952).  

Hesselman graduated in 1899 from KTH Royal Institute of Technology, Department of Mechanics.
He  worked from 1899 to 1916 for AB Diesel Engines (later Atlas Diesel, now Atlas Copco) in Sickla in Nacka just outside Stockholm, from 1901 as Head of Construction. Here he also developed Rudolf Diesel's engine further and won international recognition as an authority on diesel engines. In 1916 he opened his own factory and in 1925 presented the Hesselman engine, a hybrid between an Otto engine and diesel engine. 

Jonas Hesselman also designed electrical vehicle components, among others, the motor that became the basis for Hesselman Elhydraulik, now Haldex AB. In 1970, Hesselman Elhydraulik developed the hydraulic power unit that still serves as the prototype for the existing lifts for trucks. 

Jonas Hesselman was a resident of "Villa Hesselman" at  Storängen  outside Stockholm. The villa was designed in 1906 by architect  Albin Brag (1878-1937).  He lived here until his death in 1957.

Blackburn Airedale. The Blackburn R.2 Airedale was a single-engine three-seat monoplane deck-landing aircraft for land and sea reconnaissance, built in the UK in 1924. Only two were built.

Development
The Airedale was designed by F.A.Bumpus to Air Ministry specifications R.37/22 calling for a three-seat deck-landing reconnaissance aircraft intended to replace the Fleet Air Arm's Blackburn B.1 Blackburn and the Avro 555 Bison. Unlike the B.1, it was a monoplane with a high wing for good visibility.

The wooden-sparred thick wing was of low aspect ratio, with a maximum chord section of about 38% of the span. This chord was maintained from about ¼-½ the span with a much narrower centre section to improve vision; the wingtips were very square. The wings, braced with N-type struts to the fuselage, could be folded by rotation around an inclined axis so that they lay chord-vertical alongside the fuselage for storage aboard an aircraft carrier.

The fuselage was of semi-monocoque construction with ash longerons and a plywood covering. At the front was a metal mounting for the uncowled 385 hp (286 kW) Armstrong Siddeley Jaguar III radial engine and at the rear an empennage similar to that of the B.1. The second prototype carried small stabilising fins on the underside of the tailplane. The main undercarriage was of the single axle type complemented by a tailskid. During development the undercarriage was strengthened with two extra struts forward of the main axle which carried arrestor claws at each end for deck-landing. These engaged with the fore and aft wires used on Royal Navy carriers up to 1926.

The pilot sat in an open cockpit forward of the wing for optimum visibility during deck landings and behind him in an enclosed, windowed cabin were the navigator and wireless operator, who could access an open gunner's position further aft. The pilot was able to enter the cabin if needed, in which case the navigator could fly the aircraft from a rear folding seat provided with duplicate controls.

Operational history
Two Airedales were built, the first in 1924 for trials against the Hawker Hedgehog. It crashed after these trials and a second Airedale went to Martlesham Heath for testing in 1926. It was judged not to offer sufficient performance advantage over the B.1 and the Bison, and no orders followed. Blackburn considered a biplane derivative with a more powerful engine, the R.3A, but this remained on the drawing board.

Delta 0100. The Delta 0100 series, also Delta 100, 0300 or 300 series, was an American expendable launch system which conducted orbital launches between 1968 and 1972. It was a member of the Delta family of rockets, and the first to be designated using a four digit numerical code. Two variants were flown, individually designated Delta 0300 and Delta 0900.

The Long Tank Thor, a stretched version of the Thor missile, was used as the first stage of the Delta 0100 series. Castor-2 solid rocket boosters were attached to increase thrust at lift-off, three on the 0300 variant, and nine on the 0900. The second stage was a Delta F.

Five 0100 series rockets were launched, three using the 0300 configuration, and two in the 0900 configuration. All launches occurred from Space Launch Complex 2W at Vandenberg AFB. There was one failure, the launch of ITOS E on July 16, 1973. A hydraulic pump malfunction led to loss of pressure to the second stage attitude control thrusters, causing the launch vehicle to tumble out of control and break up in the atmosphere.

The Japanese N-I launch vehicle was derived from the Delta 0300, using a Japanese LE-3 engine on the second stage.

Capabilities 
Capacity of the Delta 0100:
 Sun-synchronous orbit (SSO), 1450 km × 101.990°: at least .

H. Milton Stewart School of Industrial and Systems Engineering. The H. Milton Stewart School of Industrial and Systems Engineering is a department in the Georgia Institute of Technology's College of Engineering dedicated to education and research in industrial engineering. The school is named after H. Milton Stewart, a local philanthropist and successful businessman who formerly graduated from the BSIE undergraduate program.

Unlike similar programs at other schools, the School of Industrial and Systems Engineering at Georgia Tech focuses on core disciplines for both Industrial Engineering (such as manufacturing and quality control) and Systems Engineering (such as global logistics and system optimization). U.S. News & World Report consistently ranks the program at number one.

Founding 
The "industrial option" for mechanical engineering was first offered at then Georgia School of Technology in 1924. The Department of Industrial Engineering was created in 1945 with Frank Groseclose as its first director and professor. In 1948, the department was elevated to its current status of School of Industrial Engineering with Groseclose serving as its first dean.

Electronic document and records management system. Electronic document and records management system (EDRMS) is a type of content management system and refers to the combined technologies of document management and records management systems as an integrated system.

Use 
Typically, systems consider a document or file to be a work-in-progress until it has undergone review, approval, lock-down, and (potentially) publication, where it will wait to be used. The version of the form that is saved containing user content will become a formal record within the organization.

Once a document achieves the status of a record, the organization may apply best-practice or legally enforced retention policies which state how the second half of the record life-cycle will progress. This typically involves retention (and protection from change), until some events occur which relate to the record and which trigger the final disposition schedule to apply to the record. Eventually, typically at a set time after these events, the record undergoes destruction.

EDRMS software 
A range of software vendors offer these systems at an enterprise level (i.e. targeted at managing all documents and records within an enterprise).

These vendors have historically provided electronic document management systems and have acquired smaller records management system companies. The seamlessness of the integration and the original intention of the records-management component to manage electronic records typically sets the complexity of deploying and potentially of using the final system.
