Messerschmitt P.1103. The Messerschmitt P.1103 Panzerjäger and P.1104 were a series of rocket-powered interceptors proposed by Messerschmitt.

Design and development 
The P.1103 and P.1104 were proposed in the early summer of 1944, with drawings for the proposals being finalized in August and September of that year.  Both were light-weight interceptors of mostly wood construction and powered by a single rocket engine.  The wings and vertical tail were adapted from the V-1 flying bomb.  The fighter would be towed into the air behind a Messerschmitt Bf 109G or Messerschmitt Me 262.

The P.1103 and P.1104 were in competition with the Heinkel P.1077 and Bachem Ba 349, the latter being selected by the Luftwaffe over the others.  Work on the P.1103 and P.1104 was abandoned in September 1944 to allow Messerchmitt to focus on the Me 262 and P.1101 projects.

Variants 
P.1103/I (P.1103A)
Initial proposal for the P.1103, dated July 6, 1944.  It was to have a low-wing configuration and be powered by a Schmidding 109-513 solid-fueled rocket engine and armed with a single 30 mm MK 108 cannon under the cockpit.  Pilot sat in a prone position with a single 30 mm MK 108 cannon under the cockpit.  External armament was proposed, with either a single Werfer-Granate 21 for aerial targets or a single Werfer-Granate 28/32 for ground targets.  Landing was to have been accomplished with a parachute.

P.1103/II (P.1103B)
Finalized proposal dated September 12, 1944.  It was to have a high-wing configuration and be powered by a liquid-fueled Walter RI 202 rocket engine.  Pilot sat in an upright position with a single 30 mm MK 108 cannon under the cockpit.  Landing was to have been accomplished with a retractable landing skid.

P.1104/I (P.1104A)
Finalized proposal dated September 12, 1944.  It was to have a mid-wing configuration and be powered by a liquid-fueled Walter HWK 109-509A-1 rocket engine.  Pilot sat in an upright position with a single 30 mm MK 108 cannon under the cockpit.  Landing was to have been accomplished with a retractable landing skid.

P.1104/II (P.1104B)
Finalized proposal dated September 12, 1944.  It was to have a high-wing configuration and be powered by a liquid-fueled Walter HWK 109-509A-1 rocket engine.  Pilot sat in an upright position with a single 30 mm MK 108 cannon under the cockpit.  Landing was to have been accomplished with a retractable landing skid.

Vigoride. Vigoride is a space tug that is under development by Momentus Space.  The total payload capacity that it can support to LEO is 750 kg.  Vigoride is capable of changing orbital planes, inclination, and propelling spacecraft to up to 2 km/s.  It also provides small satellite operators access to power, communications, and station keeping while with the tug.  Momentus states that the cost is roughly $15,000 per kg depending on the exact customer specifications.  Vigoride uses a microwave electrothermal thruster (MET) and water as the propellant.  In 2019, the first test of the MET in space was completed and was deemed a success in a press release, while the U.S. Securities and Exchange Commission accused it of misleading investors. The maiden launch was originally scheduled for January 2021, but was delayed due to Momentus not being able to receive FAA approval before the launch. On 22 March 2021, a Vigoride mock-up named Vigoride SC was launched in place of a functional Vigoride. In October 2020, the company stated that it had already booked 1.5 Vigorides out of the 3 planned to be launched in December 2021. On 25 May 2022, Momentus launched its first Vigoride spacecraft aboard SpaceX Transporter 5 mission.

Cobalt ferrite. Cobalt ferrite is a semi-hard ferrite with the chemical formula of CoFe2O4 (CoO·Fe2O3).  The substance can be considered as between soft and hard magnetic material and is usually classified as a semi-hard material.

Uses 
It is mainly used for its magnetostrictive applications like sensors and actuators  thanks to its high saturation magnetostriction (~200 ppm). CoFe2O4 has also the benefits to be rare-earth free, which makes it a good substitute for Terfenol-D. Moreover, its magnetostrictive properties can be tuned by inducing a magnetic uniaxial anisotropy. This can be done by magnetic annealing, magnetic field assisted compaction, or reaction under uniaxial pressure. This last solution has the advantage to be ultra fast (20 min) thanks to the use of spark plasma sintering. The induced magnetic anisotropy in cobalt ferrite is also beneficial to enhance the magnetoelectric effect in composite.

Cobalt ferrite can be also used as electrocatalyst for oxygen evolution reaction and as material for fabricating electrodes for electrochemical capacitors (also named supercapacitors) for energy storage. These uses take advantage of the redox reactions occurring at the surface of the ferrite. Cobalt ferrite prepared with controlled morphology and size to enhance the surface area, and thus the number of active sites, has been published. One disadvantage of the cobalt ferrite for some applications is their low electrical conductivity. Nanostructures of cobalt ferrite with different shape can be synthesized on conducting substrates, such as reduced graphene oxide, to alleviate this disadvantage.

Infrastructure Transitions Research Consortium. The UK Infrastructure Transitions Research Consortium (ITRC) was established in January 2011. The ITRC provides data and modelling to help governments, policymakers and other stakeholders in infrastructure make more sustainable and resilient infrastructure decisions. It is a collaboration between seven universities and more than 55 partners from infrastructure policy and practice.

During its first research programme, running from 2011 to 2016, ITRC developed the world's first national infrastructure system-of-systems model, known as NISMOD (National Infrastructure Systems Model) which has been used to analyse long-term investment strategies for energy, transport, digital communications, water, waste water and solid waste. This work is described in the book The Future of National Infrastructure, an introduction to the NISMOD models and tools describing their application to inform infrastructure planning in Britain.

The second phase of this programme (2016–2021) is called ITRC-MISTRAL where MISTRAL stands for Multi-Scale Infrastructure Systems Analytics. MISTRAL allowed ITRC to develop the national-scale modelling in ITRC to simulate infrastructure at city, regional and global scales.

Based in the University of Oxford's Environmental Change Institute, ITRC is led by Director Jim Hall who is also Professor of Environmental Risks at the University of Oxford.

Funding: The ITRC is funded by two programme grants from the UK Engineering and Physical Science and Research Council (EPSRC). The 2011–2016 ITRC programme grant was £4.7m and the 2016–2021 grant, for ITRC-MISTRAL, is £5.4m.

Consortium: The seven universities making up the ITRC consortium are: University of Southampton, University of Oxford, Newcastle University, Cardiff University, University of Cambridge, University of Leeds and University of Sussex.

Partners: ITRC's partners are from across the infrastructure sector. They include infrastructure investors such as the World Bank, consultancies including Ordnance Survey and KPMG, providers such as Siemens, High Speed 2 (HS2), Network Rail and National Grid, policy-makers (i.e. Environment Agency) and regulatory bodies (OFCOM).

Time-varying phasor. In communication theory, time-varying phasors are used for analyzing narrow-band signals, whose signal bandwidths in the frequency domain are considerably smaller than the carrier frequency. Time-varying phasors are mostly used for analysis of frequency domain of band-pass systems. The method uses classical impulse response.

In electrical power system, phasors are used for transient analysis of the power system keeping the quasi-stationary conditions. They were introduced to facilitate the computation and analysis of power systems in stationary operation. Time-varying phasors are used in dynamic analysis of a large power system. The phasor representation of sinusoidal voltages and currents is generalized to arbitrary waveforms. This mathematical transformation eliminates the 60 Hertz (Hz) carrier which is the only time-varying element in the stationary case. The longer usage of time-varying phasors in large power systems since 1920s have created many misconceptions. One of the misuses suggest that quasi-stationary models are always accurate, but only when the system dynamics are slow as compared to nominal system frequency which is usually 60 Hz.

The concern to study time-varying phasors is raised to understand in-depth the fast amplitude and phase variations of emerging electrical power generator technologies. This is because current and voltage signals of latest machines may have harmonic components and they can damage the entire transmission system which is coupled with the machine. However, if we employ quasi-static model, we can accurately model AC signals by using time-varying phasors as opposed to traditional quasi-static model which supports constant voltage and current signals throughout the network.

Bruce Aikenhead. Bruce Alexander Aikenhead, OC (September 22, 1923 – August 5, 2019) was a Canadian aerospace engineer and physicist. Aikenhead was widely regarded as a major pioneer in the Canadian aerospace industry, who was the deputy program director for the program that developed the Canadarm, was the first Director-General of the Canadian Astronaut Program, and helped create flight simulators for the Avro Arrow project.

Biography 
Aikenhead was born in Didsbury, Alberta, in 1923, but was raised in London, Ontario after moving there with his family as a young child. During WWII, he helped service radar equipment in the Royal Canadian Air Force. After the war, he enrolled at the University of Western Ontario and earned a degree in radio physics. He got married in 1947, at age 24. In 1955, he began working at Canadian Aviation Electronics where he helped create aircraft simulators, and in 1958, he relocated to Malton, Ontario where he helped develop Avro Arrow flight simulators for Avro Canada. Although he only held that job for 6 months due to the cancellation of the program, he quickly began working for NASA. There, he helped with the training of astronauts on the Mercury mission and also helped develop simulators for the spacecraft used in the mission. When the NASA human space flight program moved to Houston, he left NASA and rejoined Canadian Aviation Electronics, but he quickly returned to the space sector, in 1966, when he began working with Gerald Bull, a scientist at McGill University. After he left in 1967 when the funding for the program he was working on was withdrawn, he began at RCA Canada where he helped engineer the ISIS 2 spacecraft and other satellites and spacecraft. In 1981, he became the deputy program director for what became the Canadarm project at the National Research Council of Canada. He was instrumental in the process that chose the first Canadian astronaut, Marc Garneau. He later became the first Director-General of the Canadian Astronaut Program. He retired in 1993, and in 1997, he was awarded the Order of Canada. His wife died in 2005. He was instrumental in the founding of the Okanagan Science Centre in Vernon, British Columbia. On August 5, 2019, he died due to natural causes at the age of 95.

HCS Palinurus (1823). HCS Palinurus (or Palinurius) was a sloop or brig that the Bombay Dockyard launched in 1823 for the Bombay Marine, the naval arm of the British East India Company. She served as a pilot ship, survey vessel mapping the Red Sea and the coast of Yemen and Oman, and generally as a naval ship. She was still listed in 1862.

Career
The Bombay Marine used Palinurus as a survey vessel. Between 1829 and 1833 Robert Moresby captained Palinarus. Together with Thomas Elwon, in HCS Benares, he mapped the Red Sea. In 1830 Palinarus underwent refitting in Bombay after she had mapped the Gulf of Suez. After Moresby left Palinarus in 1833, she continued her surveying under the command of Captain Stafford B. Haines, who would later become the first British official in charge of the Protectorate of Aden. He surveyed  the southern coast of Arabia.

On 18 December 1836 the whaler  was wrecked on or foundered near Al Sawda (Soda) Island in the Curia Maria Islands, off the coast of Oman. Palinurus rescued the crew.

In 1838 Palinarius appeared on a list of vessels of the Indian Navy, which rated her as a brig of the 4th Class.

On 4 August 1843 the paddle steam-frigate  wrecked on Cape Guardafui. When Captain Sir Robert Oliver, Superintendent of the Indian Navy, heard of the loss, he recalled to Bombay Palinurus from Kurrachee where she was serving as a guardship. He then directed Lieutenant C.D.Campbell, her commander to sail to the wreck site to conduct salvage operations. Palinurus arrived at Bombay on 7 October, sailed on 17 October after having taken on the necessary diving equipment, and arrived at the wreck site on 31 October. She returned to Bombay on 2 June, having twice visited Aden to deliver the salvaged stores and her two 68-pounder guns.

Fate
Palinurus was listed in 1862.
