Barry Railway Class E. Barry Railway Class E were  steam locomotives of the Barry Railway in South Wales.  They were designed by J. H. Hosgood and built by Hudswell Clarke.  The locomotive was designed for light shunting duties at the docks.  Their small size made them particularly suited to shunting on the Barry Island Breakwater.  Access to the breakwater was via a rough hewn tunnel whose dimensions and sharp curves made it impossible for the other locomotives to negotiate a way through.

Traffic duties
After their initial use as shunting locomotives, they took on passenger duties on the Vale of Glamorgan Railway.  Two sets of two coaches were prepared for the role.  They comprised a four-wheeled 1888 composite coach and a six-wheeled 1895 brake third which were close coupled.  They were known as 'Motor Sets'.  At one end of the brake third was a driver's compartment which, unusually, did not have regulator equipment to control the locomotive fitted.  Instead a bell system was installed so that the driver could send instructions to the fireman in the locomotive.  The controls available in the driver's compartment were a brake and whistle controls which were operated by wires that ran along the top of the coaches and were attached to pulleys located on the dome and cab roof.  The E Class operated with one set as a push-pull unit or with both sets located either side of the engine.  This arrangement was used mainly on trains between Barry and Llantwit Major.  However, when John Auld was appointed as Locomotive Superintendent in 1909, he did not favour the push-pull arrangement and subsequently ordered that trains should revert to running the engine around the train at the end of its journey.

Withdrawal
The locomotives passed to the Great Western Railway in 1922 and 2 passed to British Railways in 1947.  All were withdrawn between 1932 and 1949.  None have been preserved.

Bally B-17. The Bally Bomber B-17 is a single-seat homebuilt aircraft, intended as a one-third scale replica of the Boeing B-17 Flying Fortress. The Bally Bomber made its debut during the 2018 EAA AirVenture Oshkosh.

Design and development

The Bally Bomber B-17 is an original design by Jack Bally, EAA 348338. The aircraft is a four-engined, retractable conventional landing gear equipped, low wing monoplane. The fuselage is all riveted aluminum in construction with hexagonal bulkheads. The drawings were modified from a one ninth scale set of radio-controlled aircraft plans. Despite being a scale replica, the aircraft is relatively large for a homebuilt aircraft due to its  wingspan. Most homebuilt aircraft are single engine designs with a few twin engine models produced, making the Bally Bomber's four-engined homebuilt a rarity.

The Bally Bomber took Bally 17 years and an estimated 40,000 man-hours to build.

Operational History

The Bally Bomber officially debuted at the 2018 EAA AirVenture Convention held annually in Oshkosh, Wisconsin. The aircraft's test pilot was Richard Kosi, EAA 666459, who also acted as an EAA technical counselor on the build. A prior unintentional flight occurred in 2016, when an unexpected gust resulted in a takeoff during a taxi test. Later in 2018, the aircraft was put up for sale by Bally. Larry Neu, EAA 104067, bought the Bally Bomber and returned to AirVenture in 2021 piloting the aircraft.

Resistograph. Resistograph is a mechanical resistance measurement device, developed by Frank Rinn (since 1986 in Heidelberg, Germany).

Driven by a drill motor, a long, thin needle is inserted into a wood log or structural wood beam in order to gain an idea of its density, often to identify areas of substandard structural integrity such as decay. Variations in resistance to torque are recorded by a stylus on graph paper. Newer models may record information digitally but the purpose of the instrument is the same.

Emitter turn off thyristor. The Emitter Turn Off Thyristor (ETO) is a type of thyristor that uses a MOSFET to turn on and turn off. It combines the advantages of both the GTO and MOSFET. It has two gates - one normal gate for turn on and one with a series MOSFET for turn off.

History

The first generation ETO was developed by Prof. Alex Q. Huang in the Center for Power Electronics, Virginia Tech, in 1996. Although the ETO concept was demonstrated, the first-generation ETO had limitations that prevented high-power applications. The device rating was later improved to 4500V/4000A.

Device Description

Turn On

An ETO is turned ON by applying positive voltages to gates, gate 1, and gate 2. When a positive voltage is applied to gate 2, it turns on the MOSFET that is connected in series with the cathode terminal of the PNPN thyristor structure. The positive voltage applied to gate 1 turns off the MOSFET connected to the gate terminal of the thyristor.

Turn Off

When a turn-off negative voltage signal is applied to the MOSFET connected to the cathode, it turns off and transfers all the current away from the cathode (N-emitter of the NPN transistor in the thyristor) into the base gate via MOSFET connected to the gate of the thyristor. This stops regenerative latching process and results in a fast turn-off. Both the MOSFET connected to the cathode and MOSFET connected to the gate of the thyristor is not subjected to high-voltage stresses irrespective of the magnitude of the voltage on the ETO, due to the internal structure of the thyristor containing a P-N junction. The drawback of connecting a MOSFET in series is that it has to carry the main thyristor current, and it also increases the total voltage drop by about 0.3 to 0.5V and its corresponding losses. Similar to a GTO, the ETO has a long turn-off tail of current at the end of the turn-off and the next turn-on must wait until the residual charge on the anode side is dissipated through the recombination process.

Pulse programming. Pulse programming in the field of experimental physics refers to engineering sinusoidal electromagnetic waveforms to have programmable frequencies, phases, and amplitudes. The main techniques and terminology arose in the study of nuclear magnetic resonance (NMR) during the 1970s, but has since been adopted in many other experimental settings, usually associated with quantum computing experiments. These include electron spin resonance (ESR), trapped ions, quantum dots, the phase/flux/charge across a superconducting junctions, and many other quantum bit implementations. Traditionally, pulse programmers were built using hard-wired analog electronics to produce a fixed sequence of waveforms, but modern pulse programmers make use of direct digital synthesis programmable electronics controlled by a personal computer to make precisely reproducible sequences.

Open source pulse programming 
There are several commercial pulse programmers available whose designs are proprietary. A notable open source pulse programmer system was originally designed by Paul Pham as part of his master's thesis at MIT under Isaac Chuang. It was first deployed in Rainer Blatt's quantum optics and spectroscopy group  at the University of Innsbruck, and was later adopted by the following trapped ion research groups:
 Tobias Schaetz's quantum analog simulation group at the Max Planck Institute of Quantum Optics, now at the University of Freiburg
 Piet Schmidt's quantum metrology group at the Physikalisch-Technische Bundesanstalt (PTB), the German national standards body analogous to NIST in the United States.
 Boris Blinov's ion trap group at the University of Washington in Seattle
 Hartmut Haeffner's ion trap group at the University of California in Berkeley
 Tilman Pfau's quantum optics group at the University of Stuttgart
 Andrew Drewson's ion trap group at the University of Aarhus

Further extensions to the system were designed and implemented by Paul Pham while he resided at 419 Boylston in Seattle, with major contributions from Philipp Schindler at Innsbruck and Lutz Petersen at MPQ. As of 2010, the core part of the pulse programmer system (the FPGA sequencer board) is no longer being actively maintained. However, the Innsbruck group has designed and assembled its own custom DDS boards which generate the actual waveforms that is compatible with the FPGA sequencer board.

A new open source system called ARTIQ is being developed by M-Labs.
