Mosaicity. In crystallography, mosaicity is a measure of the spread of crystal plane orientations. A mosaic crystal is an idealized model of an imperfect crystal, imagined to consist of numerous small perfect crystals (crystallites) that are to some extent randomly misoriented. Empirically, mosaicities can be determined by measuring rocking curves. Diffraction by mosaics is described by the Darwin–Hamilton equations.

The mosaic crystal model goes back to a theoretical analysis of X-ray diffraction by C. G. Darwin (1922). Currently, most studies follow Darwin in assuming a Gaussian distribution of crystallite orientations centered on some reference orientation. The mosaicity is commonly equated with the standard deviation of this distribution.

Applications and notable materials 

An important application of mosaic crystals is in monochromators for x-ray and neutron radiation. The mosaicity enhances the reflected flux, and allows for some phase-space transformation.

Pyrolitic graphite (PG) can be produced in form of mosaic crystals (HOPG: highly ordered PG) with controlled mosaicity of up to a few degrees.

Diffraction by mosaic crystals: the Darwin–Hamilton equations 

To describe diffraction by a thick mosaic crystal, it is usually assumed that the constituent crystallites are so thin that each of them reflects at most a small fraction of the incident beam. Primary extinction and other dynamical diffraction effects can then be neglected. Reflections by different crystallites add incoherently, and can therefore be treated by classical transport theory. When only beams within the scattering plane are considered, then they obey the Darwin–Hamilton equations (Darwin 1922, Hamilton 1957),

where  are the directions of the incident and diffracted beam,  are the corresponding currents, μ is the Bragg reflectivity, and σ accounts for losses by absorption and by thermal and elastic diffuse scattering. A generic analytical solution has been obtained remarkably late (Sears 1997; for the case σ=0 Bacon/Lowde 1948). An exact treatment must allow for three-dimensional trajectories of multiply reflected radiation. The Darwin–Hamilton equations are then replaced by a Boltzmann equation with a very special transport kernel. In most cases, resulting corrections to the Darwin–Hamilton–Sears solutions are rather small (Wuttke 2014).

Blue Flag (Israeli Air Force exercise). Blue Flag is an international military aviation exercise held by the Israeli Air Force (IAF). It first took place in November 2013 at Ovda Airbase in Israel. The exercise, which included the participation of several foreign air forces, is aimed at expanding international cooperation. Plans on making Blue Flag (named after the IAF's ensign) a biennial event were realised in 2015 with another Blue Flag exercise in which the air forces of the United States, Greece and Poland also participated. The goal of the Blue Flag training exercise is to simulate extreme combat scenarios and coalition flights as realistically as possible.

In 2017 the exercise hosted air forces from the United States of America, Poland, Italy and Greece – and for the first time India, France and Germany participated as well.

The Royal Air Force of the United Kingdom took part in Blue Flag 2021, which was the first time they have openly trained in Israeli airspace.

In 2023, Blue Flag was canceled due to the Hamas terror attack and the Gaza War.

Interceptor ditch. In geotechnical engineering, an interceptor ditch is a small ditch or channel constructed to intercept and drain water to an area where it can be safely discharged. These are used for excavation purposes of limited depth made in a coarse-grained soils. These are constructed around an area to be dewatered. Sump pits are also placed at suitable intervals for installation of centrifugal pumps to remove the water collected in an efficient manner. In fine sands and silts, there may be sloughing, erosion or quick conditions. For such type of soils the method is confined to a depth of 1 to 2 m. Interceptor ditches are most economical for carrying away water which emerge on the slopes and near the bottom of the foundation pit. Its size depends on the original ground slope, runoff area, type  of soil and vegetation, and other factors related to runoff volume.

Construction guidelines
 The interceptor ditch commonly consists of a ditch and may have an associated dike. 
 Sediment control measures may be required to filter or trap sediments before the runoff leaves the construction area.
 The construction of the interceptor ditch at the crown of a slope is normally accomplished prior to the excavation of the cut section.

Maintenance
Inspection and maintenance is necessary after completion of construction of any structure. Here some steps followed in the maintenance of interceptor ditches are summarized below:
 Periodic inspection and maintenance will be required based on post-construction site conditions. 
 Make any repairs necessary to ensure that it is operating properly. 
 Locate any damaged areas and repair as necessary.
 Remove any channel obstructions (particularly waste materials) which would otherwise obstruct dewatering.

Human sensing. Human sensing (also called human detection or human presence detection) encompasses a range of technologies for detecting the presence of a human body in an area of space, typically without the intentional participation of the detected person. Common applications include search and rescue, surveillance, and customer analytics (for example, people counters).

Modern technologies proposed or deployed for human sensing include:

 Acoustic sensors
 Image recognition of human shapes
 Infrared detectors
 Pressure-sensitive floor tiles
 Radar
 Chemical sensors
 Detection of the mobile phone, computer, Bluetooth, or Wi-Fi signals of a device assumed to be in the possession of a person.
WiFi Sensing

Examples
In 1997 CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart") was invented. A test is presented to detect that a computer is being used by a human operator, preventing access to a protected resource by programs such as spam robots.

Various commercial heartbeat detection systems employ a set of vibration or seismic sensors to detect the presence of a person inside a vehicle or container by sensing vibrations caused by the human heartbeat.

Another commercial product uses infrared light to detect the level of carbon dioxide in an enclosed space, from which it infers the presence of humans or other living creatures.

In September 2013, the United States Department of Homeland Security's Science and Technology Directorate demonstrated a prototype of the FINDER radar technology device, which it developed in conjunction with NASA's Jet Propulsion Laboratory. FINDER uses microwave radar to detect the unique signature of a human's breathing pattern and heartbeat, through 20 feet of solid concrete, 30 feet of a crushed mixture of concrete and rebar, and 100 feet of open space.

In September 2014, the DHS promoted the technology to SWAT teams at the Urban Shield trade show.

In 2019, waste management company Total Waste Solutions developed a device to help protect homeless people who seek shelter inside industrial bins from harm.
