LLNL RISE process. The LLNL RISE process was an experimental shale oil extraction technology developed by the Lawrence Livermore National Laboratory. The name comes from the abbreviation of the  Lawrence Livermore National Laboratory and words 'rubble in situ extraction'.

LLNL RISE is a modified in situ extraction technology originally proposed by Rio Blanco Oil Shale Co. and developed by the Lawrence Livermore National Laboratory.  It is classified as an internal combustion technology.  The process was described in 1975 by Lewis A. E. and A. J. Rothman.

In the LLNL RISE process a part of the oil shale deposit (roughly 20% of the total deposit) is removed by the conventional mining technique. The remaining deposit is then broken up with explosives to increase porosity of the deposit. As a result, a large underground retort chamber by  square and  high is created. The retort chamber is ignited  at the top. The combustion zone moves downward as an oxygen gas provided, similar to the process developed by the Occidental Petroleum. The heat causes retorting process converting kerogen in oil shale to oil shale gas and shale oil vapors.  Some oil is collected at the bottom of the retort, other collected at the surface as vapors.

The process was never used commercially. It was tested by using experimental  simulated retort with capacity of 6 tonnes of oil shale per day.

Boring bar. A boring bar is a tool used in metalworking and woodworking. Boring is a technique used in many aspects of building. Woodworkers have used boring as a form of drilling for centuries. In woodworking, the boring tool is static in size and used to form circular plunge cuts. In metalworking, boring is slightly different in that the hole that results need not be circular. In metal boring the tool can be plunged and dragged on the X or Y axes to create a slot or asymmetrical hole or channel, or it may be moved only in an up-and-down motion (on the Z axis) to create a perfect circular hole.

Components
Modern boring tools have three primary components although many differing designs. The parts include the body, bar holder and dial screw (graduated micro screw). The body, made of solid stock, has two basic parts. The top part threads or presses into the supporting shank. The lower part (bar holder) is connected via dovetail, T-slots or a smooth notch with an adjustment for bore diameter via the dial screw. As the dial screw is adjusted, the cutting bit/s are moved further out, creating a larger cut. This also can create some slight distortion if the cutting tool is moved further than the boring head is designed to support, if there is undue wear in the bearings supporting the tool or if the tool speed is too great for the off-balance effect caused by moving the tool too far from center. This is called unbalanced gyroscope precession. Once the dial screw has been adjusted to give the proper cut a set screw is generally used to prevent any additional movement of the cutting head. The third basic part is the boring tool. Boring tools can be mounted vertically or horizontally in many boring head designs.

Boring machines
Boring can be done on mills, lathes or drill press machines, either with a boring head or with just a boring tool. The shorter the distance between the tool holder and the material, the less distortion created from vibration or unbalanced gyroscopic effects. The greater the distance (static or dynamic mounts) the more flex in the tool or an increase in the imbalance of a moving tool. Use of a boring head increases the mass of the tool holder and decreases the distance. If a vibration is created it will be at a higher frequency and the deflection of the tool from the desired path will be much smaller and easier to erase through repetitive tool passes. In the case of a dynamic tool (mill or press), the balance of the tool can be adjusted with counterweights if the tool is mounted perpendicular to the shaft or the tool length can be decreased.

Α-Phenylcinnamic acid. α-Phenylcinnamic acid is a phenylpropanoid, or, more specifically, a derivative of cinnamic acid. It has the formula C15H12O2 and appears as an off-white crystalline solid.

Uses
α-Phenylcinnamic acid is frequently used as a compound synthesized in undergraduate laboratories to study the Perkin reaction, but is primarily seen as in intermediate or precursor to other, more useful phenylpropanoids.

Synthesis 
There are many ways to synthesize α-phenylcinnamic acid. Some of the more popular methods of formation include the condensation of phenacyl chloride with benzaldehyde in the presence of triethylamine, the distillation of benzylmandelic acid, or by the reaction of sodium phenylacetate with benzaldehyde in acetic anhydride. There are two isomers of this compound, differing in the geometry of the alkene. The E isomer, in which the two phenyl rings are cis to each other, is the major product formed by most synthetic routes. However, this compound can be converted using heat or ultraviolet light into a mixture containing nearly 50% of the Z isomer.  Decarboxylation of α-phenylcinnamic acid yields stilbene, with the (E) isomer producing cis-stilbene and the (Z)-isomer producing trans-stilbene.

Confidence Bay. Confidence Bay was the first mobile high-definition edit suite in the world. The facility is a 35' recreational vehicle with two full editing bays inside. It debuted in March 2006 at South by Southwest (SXSW) in Austin, Texas.

Design philosophy
The interior of the truck was designed to focus on the comfort of the passengers instead of focusing on the technology. Most of the tech is hidden out of view with only the displays, keyboards, and such being visible. The vehicle has two slide-out compartments that expand the interior to . The custom cabinetry and counters were created by Gerry Burgess. The counter tops and several of the cabinets feature rounded edges which were created by steaming and bending the wood over time. The floor is covered with laminate hardwood flooring.

There's a video projector inside the RV that points to a dual-vision projection screen in front of a 16:9 aspect window in the side of the RV. At night the images projected onto the screen are visible to anybody standing outside the truck. This was designed to allow large groups of crew members to view footage without having to crowd into the truck.

The technology used in Confidence Bay is customized to the needs of the project. By default, the systems are multi-processor MacPro towers with Final Cut Studio, but the tech has been reconfigured in the past for AVID, Premiere, and Sony Vegas. The infrastructure is designed to work with any desktop platform.

Power
The power system on Confidence Bay is a double conversion power system. Alternating Current (AC) power is fed into a high power battery charger that feeds 12 V direct current (DC) into  of deep cycle marine batteries. Two 2000 W ProSine inverters use the power from the battery bank and feed pristine 120 V AC power to the two editing systems. This configuration completely isolates the sensitive electronics onboard from any spikes, sags, blackouts, or otherwise irregular power fluctuations that frequently occur when plugging into some generators or less than ideal electricity sources. This also allows the systems to remain up and fully functional while completely disconnected from any power source at all for close to an hour at moderate electrical load.

The truck does have a 5.5 kW gasoline generator which can run continuously for over 3 days if grid power is not available. The fuel supply is the 75 gallon gas tank used by the RV's engine. The generator will shut off when the gas gets down to 1/8 of a tank to prevent running the tank dry.

Delta Electric Company. The Delta Electric Company was an American electronics manufacturer formed in 1913 in Marion, Indiana that produced lanterns, flashlights, automotive and bicycle lighting, battery tubes, horns, horn buttons, light switches, other battery-powered electrical parts, and bilge pumps. It was moved to Marion from an existing business in Chicago following a stock purchase.

Delta was purchased in 1964 or 1965 by the Novo Industrial Corporation. One of Novo Industrial Corp.'s subsidiary companies, King Bee Manufacturing Co., was moved to Marion, and its line of automotive lighting and safety equipment, including headlamps, safety lights, directional lights, mirrors, and reflectors for trucks, buses, trailers, and farm tractors, was merged into the Delta line of products.

United Air Cleaner (UAC) was a division of Nova Industrial Corp. that produced air cleaners.

Delta Electric was a division of Novo Industrial Corp. until 1968 when Novo became part of United Filtration Corp. Delta continued to operate as a division of United Filtration. After selling off the line of bicycle accessories, Delta continued to produce accessories for the automotive industry such as truck side-view mirrors and various automotive switches. By 1976 the company's main line had become warning buzzers for fire and security alarms.

Halle Industries Inc. had acquired Delta in 1977, and on March 31, 1978, shut down production of Delta Electric due to losing contracts for their smoke detector alarms to Japanese imports.

HP 30b. The HP 30b (NW238AA, variously codenamed "Big Euro", "Mid Euro" and "Fox") is a programmable financial calculator from HP which was released on 7 January 2010. The HP 30b is an advanced version of the HP's prior model HP 20b. Featuring a two line alpha numeric display, ability to input data via Reverse Polish Notation, Algebraic and normal Chain algebraic methods, and twelve digit display.

This ARM powered calculator also has some limited scientific functions which is relatively rare in financial calculators. Also, it has a built in Black-Scholes Equation, for calculating theoretical premium for calls and puts, Modified Internal Rate of Return and Financial Management Rate of Return, a first.

The HP 30b is not allowed in any major exam like CFA Charter exam.

HP 40b
At some point HP planned to release a HP 40b, a version of the HP 30b with added USB port, the capability to load precompiled programs into the calculator from the PC and to use the calculator as an external keypad for a PC. However, only a few prototypes were ever produced.

WP 31S, WP 34S and WP 34C

As with the HP 20b, the HP 30b's firmware can be overwritten ("flashed") using a computer and a special cable. Taking advantage of this facility, a team of HP calculator enthusiasts has produced a firmware for converting the 30b into a programmable scientific calculator. The resulting WP 34S (2011) firmware and user's manual can be downloaded free of charge, and a special serial cable and keypad overlay can be purchased for a nominal fee. The WP 34S was also being sold commercially. A firmware branch with a complex number lock mode is called WP 34C (2015). The WP 31S (2014) is a stripped-down version of the WP 34S. (The community-developed WP 43S, which is based on the SwissMicros DM42 hardware, is a successor to this project.)
