Locations for the two sharks, named Lydia and Mary Lee by the OCEARCH tagging team. Pink dots are locations inside eddies, green dots are in “meanders” of the Gulf Stream, and black dots are outside these features. The shading of the ocean shows changes in the height of the ocean’s surface, the signature of eddies. Image Credit: Peter Gaube/University of Washington
Photographic techniques capture electromagnetic wavelengths beyond human vision, revealing features invisible to the naked eye. These signals are processed into interpretable forms using methods like color mapping.
Pink lacks a specific electromagnetic wavelength, while grey poses a limitation due to its representation of only intensity—a blend of light and dark without spectral specificity. Imaging techniques reliant on spectral variation produce identical results for greyscale images unless non-visible data is present. Deviations from this uniformity may indicate errors, misinterpretations, or unknown phenomena.
Contention persists over analytical debates, including dismissible claims like Van Allen belt dangers and contested evidence of lunar mirrors. The precision of laser reflections targeting a moving 3x3-foot marker on the Moon highlights technical skill but often fails to resolve skepticism. For instance, a 0.1° shift moves a laser spot 670 km across the Moon's surface.
Forensic analysis (2022, 2023) of Apollo 11–17 photographs assessed authenticity claims. Images of humans in space, Earth, and the Moon's distant views were validated, but Moon landing visuals showed variations, suggesting diverse techniques may have replicated certain elements.
PEMi (Photoelectromagnetic Image) software enhances forensic analysis by differentiating natural and artificial light sources, revealing hidden features. Each PEMi-ID links to original sources, ensuring traceability and comparison.

Before our site visit to worlds end, we were asked to create a site analysis model to represent what we have researched on worlds end.
After my partner and I did our research, we focused on what we thought was the most interesting element of worlds end.
Designed by the landscape architect Frederick Olmstead around 1889, one of his biggest contribution to the site was the double tree lined path. The avenues of tree provides protection from the sun in the summer, as well as a way to guide and frame views of elements of the site. these views include small vignettes within the sites as well as views out around the boston harbor.
The horizontal elements in the model represents the path which weaves up and down. The vertical sticks acts as a form of guidance while providing various forms of gaps and opening representing the different types of viewing platform of the site.
One of my colleagues has amazingly neat blackboard writing and I managed to capture this sample of it when he wasn't looking. Beautiful isn't it?

A local nature preserve has a gallery for local photographers, like myself, to display nature themed artwork. Mine runs from now through Feb. 22nd at Emily Oaks Nature Preserve with a reception on the 9th of Jan.
First the image was converted into a set data vectors in format (x,y,r,g,b), one for each pixel in image.
Then this 5D-data was projected to 3D-space using principal component analysis, The resulting image was rebuilt based on that reduced information.
This is a photograph that I took when I was exploring eyes.
My work is within the genre of portraits as the subject is an infants face. I was very interested in this model as his eyes were a deep blue and easily showed beautiful patterns without having to look closely. The other colours in the image such as his clothes also help to emphasise the model's eyes as they're also blue.
I think that this is a successful photo as although there is a lot in the frame, you are instantly drawn into the eyes as the focal point.
When capturing this photograph I took into consideration the composition. Using the rule of thirds I thought about what man colours used: blue, red, skin colour, and also how many parts leave the frame such as the models head and each side of the body.
I ensured that the subject of matter was not central to prevent the image from looking basic. As you can see by the grid, I captured the image so that the model was not looking straight ahead and the face was slightly to the left. If I hadn't taken this into consideration the photograph would not be unique. As this is an extreme close up, it is not clear to pick out a background, midground and foreground.
Dr. Ruben Morawicki and lab technician Delmy Diaz use colorimetric analysis to determine protein content of fermented sorghum samples. Fermentation increases protein content and also makes it more available for digestion in animal feed.
Wilde and NAMTEC hosted a one-day awareness seminar on “Improving Design by Simulation: The Benefits of ANSYS to Industry”
The seminar held at NAMTEC on 16th October 2008 was a “resounding success” said David Deakin, Managing Director of Wilde.
Hosted by Wilde in conjunction with NAMTEC, seminar focused on the success companies have gained from the ANSYS range of CAD-integrated structural, thermal and computational fluid dynamics programs, both in-house and through the use of consultants.
More than 95% of delegates were satisfied with the event and found it “enjoyable, relevant and beneficial”.
Modal decomposition test set allows us to measure individual cabling components such as cable, cordage and connection (mated plug and jack) separately, then cascades them using a pre-determined configuration mathematically. A sizable number of simulations (more than 1,000) can be done within a short period of time. This powerful simulator allows CommScope to assess the link and channel performance much more accurately than what the cabling industry has adopted at this time. Path analysis toolkit is utilized to reduce the number of prototype iterations by mathematically changing the property of the targeted connecting hardware. The test set together with the software enable us to quickly and accurately assess the electrical performance of copper cabling solutions, reduce the number of prototype iterations and provide a statistical base for our performance claims. The major impact to the industry is to reveal the importance of mode conversion parameters (balance) to the design of a Cat-6A UTP cabling system. TIA and ISO/IEC did not treat the balance terms seriously until we showed them our findings. www.commscope.com/top-40-innovations/
A forensic science laboratory may use fingerprints or DNA to identify the victim of a crime or identify or rule out a suspect. Students will learn about the features of fingerprints, and their scientific examination in the first year of our courses.
