Femto Photography
The seemingly impossible task of recording what is beyond the line of sight is possible due to ultra‐fast imaging. A new form of photography, Femto-photography exploits the finite speed of light and analyzes 'echoes of light'.
Femto-photography consists of femtosecond laser illumination, picosecond-accurate detectors and mathematical inversion techniques. By emitting short laser pulses and analyzing multi-bounce reflections we can estimate hidden geometry. In transient light transport, we account for the fact that speed of light is finite. Light travels ~1 foot/nanosecond and by sampling the light at pico-second resolution, we can estimate shapes with centimeter accuracy.
Potential applications include search and rescue planning in hazardous conditions, collision avoidance for cars, and robots in industrial environments. Transient imaging also has significant potential benefits in medical imaging that could allow endoscopes to view around obstacles inside the human body.

Radiation can cause damage to cells and DNA which may lead to cancer or genetic mutations. The main dangers of ionising radiation are killing healthy cells, stimulating cancer growth, and causing mutations to DNA that can be passed down generations. Radiation exposure is measured in dosage, and dosimeters are used to monitor the dose received by individuals. Protective measures include increasing distance from sources of radiation, limiting exposure time, and using shielding such as lead to absorb radiation.

Presentation on edt
This document discusses electrodynamic tethers, which use the Lorentz force from the interaction of electric current in the tether and the Earth's magnetic field to produce propulsion. It provides a history of tethers, explains how they work based on electromagnetic principles, and discusses their applications such as deorbiting satellites. Electrodynamic tethers provide a propellantless option for orbital maneuvers but require stabilization techniques due to inherent instability. They have advantages of being reusable, environmentally friendly, and low-cost compared to traditional chemical rockets.
Laser
Laser is a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. Lasers work through three interactions with atoms: absorption of radiation, spontaneous emission, and stimulated emission. Absorption occurs when electrons absorb energy from photons and jump to a higher energy level. Spontaneous emission is when excited electrons return to the ground state and emit photons randomly. Stimulated emission is when an incident photon interacts with an excited electron and forces it to return to the ground state, emitting another photon with the same properties as the incident photon.
Sbf2016
This document discusses using ferrofluids and magnetic fields to manipulate light polarization. Ferrofluids are liquids containing magnetic nanoparticles that can form complex patterns when exposed to magnetic fields. These patterns can be observed between polarized light filters. The experimental apparatus uses a ferrofluid cell containing a magnetic field created by magnets. Different magnet configurations produce unipolar, bipolar, and multipolar field geometries, visualized by the ferrofluid patterns between crossed polarizers. Potential applications include characterizing magnets and magnetic assemblies. The patterns resemble modes in optical cavities, providing an analogy to describe the interactions between light and magnetic fields using ferrofluids.

Michelson interferometer
The Michelson interferometer uses a laser light source that is split by a beam splitter into two beams. One beam reflects off a fixed mirror and the other reflects off a movable mirror before recombining at the detector. By moving the movable mirror, the path length of one beam can be varied, causing the beams to interfere constructively or destructively at the detector and creating bright or dark fringes. This allows very small changes in distance or wavelength to be measured precisely.
Mechanical measurement and metrology
This document discusses various topics in mechanical measurement and metrology. It describes basics of optical interference and interferometry, including how optical flats can be used for flatness checking, surface contour testing, and checking parallelism. It also discusses two types of interferometers - the N.P.L. flatness interferometer and the Pitter N.P.L. gauge interferometer. The Pitter N.P.L. gauge interferometer is used for determining actual dimensions or absolute length of gauges. Finally, it provides an overview of opto-electronic measurements, describing how a simple opto-electronic inspection system works using a light source, lens assembly, and photodiode arrays.
E.m. spectrum
The electromagnetic spectrum consists of all possible frequencies of electromagnetic waves, which are classified by their frequency and wavelength and common uses. Radio waves have the longest wavelength and are used to transmit general information, while microwaves are used in microwave ovens to heat food by moving hydrogen atoms. The experiment detected microwave wavelengths by observing melted chocolate spots. Infrared radiation is emitted by thermal agitation and detected by special cameras, while ultraviolet light from the sun is responsible for many tumors. X-rays are used to see hidden objects and gamma rays have the shortest wavelengths; one hypothesis is that dark matter consists of axion particles that transform between gamma rays and photons during supernova explosions.
Lasers for mpctc
Lasers produce a coherent beam of light through stimulated emission of radiation. They have three key properties - monochromaticity, coherence, and directionality. A laser has three main components - a pump source that provides energy, a gain medium that amplifies light, and an optical resonator with mirrors. Lasers can be classified by their gain medium as solid-state, liquid, gas, excimer or semiconductor lasers. Common military applications include laser range finders, target designators, and laser-guided weapons. High energy laser weapons are also being developed for missile defense and other potential uses.
Lect15 handout
The document discusses electromagnetic waves, including their propagation, energy, intensity, and polarization. It defines that electromagnetic waves have oscillating electric and magnetic fields that change in sync as the waves propagate. The energy of electromagnetic waves comes equally from the electric and magnetic fields. Intensity is defined as power per unit area. Polarization is the direction of oscillation of the electric field and can be linear, circular, or unpolarized. Linear polarizers only transmit electric field components parallel to the transmission axis.
ELECTRODYANAMIC TETHER
1. Electrodynamic tethers use the interaction between electric current in a conducting tether and Earth's magnetic field to propel spacecraft. As the tether moves through the magnetic field, a voltage is induced along its length.
2. When current is run through the tether, the Lorentz force from the magnetic field can be used for propulsion. Current can be collected from ionospheric plasma to de-orbit a satellite or an external power source can overcome the induced voltage to boost an orbit.
3. Tethers provide propellantless propulsion and can lower the cost of in-space transportation by reducing the need to launch propellant from Earth. Potential applications include de-orbiting satellites
Polarization
This document discusses polarization of light. It defines ordinary unpolarized light as containing electric fields vibrating in all directions, resulting in no net polarization. Polarization is described as restricting the electric field to vibrate in a single plane. Two methods of achieving polarization are discussed: reflection and absorption. Polarization by reflection occurs at Brewster's angle when the reflected and refracted beams are perpendicular. Polarization can also be achieved by passing unpolarized light through materials like polaroid that absorb light vibrating in one direction. The document concludes by noting applications of polarized light.

Practical Realisation of Nuclear Pulse Propulsion
This document proposes a design for practical nuclear pulse propulsion that addresses issues with previous designs. It involves using aneutronic pure fusion bomblets to eliminate nuclear fallout, and directing the explosion energy using magnetically-driven implosions within a spherical geometry. The explosions would pump magnetic fields to contain and direct the plasma through a series of magnetic rings and generators, either reusing components for smaller repeated explosions or rebuilding the system after larger single explosions. The goal is an efficient propulsion method that overcomes limitations of prior nuclear pulse rocket attempts.
Particle accelerator
A particle accelerator is a device that uses electromagnetic fields to accelerate charged particles to high speeds and contain them in well-defined beams. They can be used for purposes like radiotherapy, ion implantation, and industrial and biomedical research. The largest particle accelerators in the world are the RHIC, the LHC at CERN, and the Tevatron, which are used for experimental particle physics research. Particle accelerators can be divided into low-energy machines like cathode ray tubes and X-ray generators, and high-energy machines capable of nuclear reactions like the LHC, which smashes particles together at high speeds to study the origins of the universe.
Auto-collimator
An auto-collimator is an optical instrument that uses a collimator and telescope combined to measure small angular differences very sensitively and accurately. It works by projecting parallel light using a collimator and measuring the linear displacement of the reflected light when the reflector is tilted, which corresponds to twice the angle of tilt. The auto-collimator responds only to tilts of the reflector, and its focal length and aperture determine its measurement range and sensitivity. It can be used to measure straightness, flatness, angles, squareness, and parallelism.
Laser interferometry
The document discusses laser interferometry, which uses lasers to make highly accurate length measurements. It describes how a laser produces coherent, monochromatic light and can be used as the light source in interferometry. Interferometry works by superimposing laser light waves to extract information about the waves. Specifically, it uses the frequency difference between two laser beams to precisely measure displacements down to 0.1mm over distances of 100m. Key components of a laser interferometer system include a dual frequency laser source, optical elements like beam splitters, and a measurement receiver and display.
Super conductors and magnetic levitation ppt
Super conductors have negligible resistance below a critical temperature. They are used in magnetic levitation trains where the repulsion between a superconductor and magnet causes levitation. Super conductors have applications in particle accelerators, medical imaging, power grids, and proposed uses in high speed trains and launching space vehicles. Magnetic levitation provides advantages over normal applications like reduced energy usage and lower operating costs for trains.
ELECTRODYNAMIC TETHER
This document discusses electrodynamic tethers, which use the Lorentz force generated by the interaction between a current in the tether and the Earth's magnetic field to propel or deorbit spacecraft. Electrodynamic tethers can be used to accelerate a spacecraft into a higher orbit or decelerate it into a lower orbit without using propellant. They work by either collecting electrons at one end of the tether and expelling them at the other end, or driving current in the opposite direction. Challenges include stabilizing the tether's motion, but feedback algorithms can help maintain stability. Potential applications include propulsion of spacecraft in low Earth orbit, deorbiting of satellites, and reboosting of decaying orbits.
Sem n tem
Electron microscopes use a beam of electrons to examine objects at a very fine scale. There are two main types - transmission electron microscopes (TEM) and scanning electron microscopes (SEM). TEMs allow study of inner structures by transmitting electrons through thin samples, while SEMs visualize surface topography by scanning sample surfaces. Both have advanced biological and materials applications due to their high resolving power and ability to produce detailed images at the nanoscale level. Recent developments include aberration correction to further improve resolution.

The document discusses the principles and equipment used in x-ray and gamma radiography, advantages and limitations of each method, and precautions for radiation safety. It provides examples of applications for radiography like casting and forging inspections.
Fiber optics laser [autosaved]
This document summarizes fiber optic lasers. It discusses that fiber lasers are optically pumped using diode lasers and have a doped fiber cavity with Bragg gratings on each end acting as mirrors. The doped fiber contains ions like erbium or ytterbium that are stimulated by the pump light to emit photons. This emission is amplified as photons bounce between the mirrors, generating laser light. Fiber lasers have applications in materials processing, scientific research, and medicine due to their stability, beam quality, efficiency and ability to generate high power. The future of fiber lasers involves increasing power output and expanding their applications.

Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error.
Magnetic Particle Testing.ppt
This document provides an overview of magnetic particle testing (MPT), a nondestructive testing method used to detect surface and near-surface discontinuities in ferromagnetic materials. MPT works by magnetizing a test specimen, which causes magnetic fields to flow through the material. Any discontinuities will disrupt these magnetic fields and create leakage fields on the surface. Iron particles coated with dye are applied and will cluster at leakage fields, revealing the location of discontinuities. The document outlines the MPT process, including pre-cleaning, magnetizing with different field directions, applying particles wet or dry, and interpreting any indications found. It also discusses limitations and advantages of MPT.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.
