Unmanned aerial photogrammetric survey. The unmanned aerial photogrammetric survey is the use of unmanned aerial vehicles (UAVs) to take photos for use in photogrammetry, the science of making measurements from photographs. Instruments manufactured for UAVs could be mounted on unmanned flying platforms of various sizes and types, such as octocopters. These machines are suitable for the full geodetic survey of a study site by creating a point cloud of measurements of nearly homogeneous quality and accuracy. These detailed point clouds (of various types of data) could be used in line with orthophotos etc. to obtain a complex data system representing the study site.

Similarly to manned aerial surveys, UAVs are suitable to acquire three-dimensional digital models and orthophoto mosaics for a certain area.

The biggest downside of this technology is that these UAVs, especially the smaller ones, could survey only a smaller area.

Comparison with manned aerial survey

Disadvantages
 Smaller UAVs are only able to survey smaller areas.
 The payload of the flying platforms is quite limited.
 The legal procedures are more complicated and lengthy than the ones for manned aerial vehicles (e.g. airplane kites).
 Reliable flying platforms of good quality are very expensive

Advantages
 The machinery could be transported to the study site by car, thus transportation costs are low.
 The deployment of the machinery is flexible.
 It can operate and produce measurements in cloudy conditions.
 The maintenance, storage, and running costs of unmanned platforms are cheaper than the same expenses of conventional aircraft. Moreover, the smaller high-quality unmanned platforms are more efficient, productive, and more durable than the conventional unmanned aircraft which could amortize quickly

Henderson H.S.F.1. The Henderson H.S.F.1 was a British six-seat low-wing monoplane designed by J. Bewsher and built by the Henderson School of Flying. Only one aircraft was built and it was scrapped in 1930 following the death of the owner George Lockhart Piercy Henderson.

Design and development
The H.S.F.1 was a twin-boom pusher monoplane powered by a  Siddeley Puma engine. Designed by J. Bewsher it was built in a shed at Byfleet in Surrey and assembled at Brooklands Aerodrome by the Henderson School of Flying in 1928. Originally built with an enclosing cabin top; this was removed and it flew its first flight at Brooklands by Henderson with an open cockpit. The aircraft carried 30 passengers in total on its first day.

In April 1930 it was tested by the Air Ministry at Martlesham Heath. Henderson died in July 1930 in the crash of a Junkers F.13 at Meopham following which the H.S.F.1 was scrapped.

Incat Crowther. Incat Crowther is an Australian marine engineering company, headquartered in Sydney. Incat Crowther has offices in Lafayette, Louisiana, United States and Eastleigh, England.

The company has a diverse product portfolio of designs for monohull, catamaran and trimaran vessels with a composite, aluminium and steel construction for a range of sectors, including commercial, recreational, military and passenger.

History
The company was created from a merger of Incat Designs - Sydney and Crowther Designs in 2005.

Crowther Design founder Lock Crowther had a history in catamaran, trimaran and commercial vessel design.

Incat Designs (Sydney, formed 1988) founder Philip Hercus had a history in passenger vessel catamaran design. In 1977, he formed a partnership, namely International Catamaran Pty Ltd designing and building catamarans in Tasmania. This combination made significant advances in fast powered catamaran technology culminating in the wave piercing catamarans.

Early in 1988, the shipyard partnership was mutually terminated and a design-only company, International Catamaran Designs Pty Ltd (Incat Designs - Sydney) was formed as part of the Hercus Marine Group. The other partner Bob Clifford then commenced designing and building under a new company, Incat.

Both merging companies have had long partnerships with the following shipyards: Gladding-Hearn Shipbuilding, Richardson Devine Marine, Nichols Bros, Gulfcraft, Cheoy Lee Shipyards, Aluminium Marine, Kvichak Marine and NQEA.

Later partnerships have emerged with: Arpoador Engenharia, Astilleros Armon, ETP Engenharia Ltda., Incat, PT Caputra Mitra Sejati Shipyard, Veecraft Marine

Over 650 vessels built to Incat Crowther designs have been delivered. These include Eleanor Roosevelt, the world's first very large catamaran Ro-Pax ferry powered by dual-fuel reciprocating engines, and New York City Ferry's 40-plus vessel fleet.

Records
A world waterskiing record of 114 Skiers by the Horsehead Water Ski Club on 28 March 2010 was set utilizing the vessel Eagle.

This record was again broken utilizing the Eagle on 27 January 2012 with 145 skiers making the nautical mile journey.

Molecular vapor deposition. Molecular vapor deposition is the gas-phase reaction between surface reactive chemicals and an appropriately receptive surface.

Often bi-functional silanes are used in which one termination of the molecule is reactive. For example, a functional chlorosilane (R-Si-Cl3) can react with surface hydroxyl groups (-OH) resulting a radicalized (R) deposition on the surface.

The advantage of a gas phase reaction over a comparable liquid phase process is the control of moisture from the ambient environment, which often results in cross polymerization of the silane leading to particulates on the treated surface. Often a heated sub-atmospheric vacuum chamber is used to allow precise control of the reactants and water content. Additionally the gas phase process allows for easy treatment of complex parts since the coverage of the reactant is generally diffusion limited. Microelectromechanical Systems (MEMS) sensors often use molecular vapor deposition as a technique to address stiction and other parasitic issues relative to surface-to-surface interactions.

Douglas D. Taylor. Douglas D. Taylor is an entrepreneur and former academic researcher in the field of extracellular vesicles.

Taylor attained a bachelor's degree from the University of Richmond and a Ph.D. from Wake Forest University. He was a post-doctoral fellow at Boston University. Taylor was a professor and Vice Chair for Research in the Department of Obstetrics, Gynecology, and Women's Healthheld at the University of Louisville in Kentucky. He was also on the faculty of the University of California, Davis. From 2013 to 2015, he was the Chief Scientific Officer of Aethlon Medical's wholly owned subsidiary, Exosome Sciences.

Taylor first described exosomes in the 1980s, originally believing them to be cell fragments. He later wrote in a now retracted paper that exosomes could potentially be used as biomarkers for profiling in ovarian cancer biopsies, and could extend their utility to screening other asymptomatic areas. What constitutes exosomes has not been defined; specifically, markers of exosomes do not exist.

In 2015, the Journal of Immunology retracted a paper it published in 2006 and which Taylor had co-written after an "institutional research misconduct investigation committee determined that multiple figures in the...paper were falsified". Taylor responded to the retraction on the blog Retraction Watch, disputing various aspects of the retraction, and stating that he sent "copies of the original data so that the [journal's] editor could independently verify that no falsification or fabrication occurred".

Tyvak. Tyvak Nano-Satellite Systems was an American company that designed and built satellites. It started as a designer, builder and provider of nanosatellite and CubeSat space vehicle products and services for government and commercial customers. Tyvak was based in Irvine, California. It was a subsidiary of Terran Orbital Corporation. In 2022, it was announced that Tyvak would transition into larger satellites from nanosats and cubesats and the name Tyvak would be phased out in favor of the name of the parent company Terran Orbital.

In 2011, Jordi Puig-Suari, co-inventor of the CubeSat design, and Scott MacGillivray, former manager of nanosatellite programs for Boeing Phantom Works, established Tyvak Nano-Satellite Systems in San Luis Obispo, California, to sell miniature avionics packages for small satellites, with the goal to increase the volume available for payloads.

On 18 November 2019, Tyvak was one of five companies selected to be eligible to bid for the NASA Commercial Lunar Payload Services (CLPS).

In 2022, Terran Orbital company, the company that owns Tyvak, entered public stock market through a SPAC merger. At the time it was announced that the name Tyvak would be phased out and the focus of the whole company (that is, both Tyvak and Terran Orbital) would be transitioned into larger satellites from nanosats and cubesats.

At the end of October 2024, Lockheed Martin acquired Terran Orbital, becoming the sole owner of the company. The company continues its existence as part of Lockheed Martin (rebranded as “Terran Orbital, a Lockheed Martin Company”) and continues to produce smallsats.
