What are Appropriate Border Surveillance Technologies? Sept. 16, 2014
Presented at USA-SOUTH AFRICA: BORDER SURVEILLANCE AND ANTI-POACHING TECHNOLOGY COOPERATION SYMPOSIUM by Mr. Francois Anderson and David Horner, PhD
KinPhy
KinPhy is a kinetic in-band channel for millimeter-wave networks that uses physically oscillating metasurfaces to backscatter information to an mm-wave router (1). It consists of a metasurface and radar reader (2). The metasurface precisely modulates the phase of reflected mm-wave signals using piezo actuators, while the reader shines a mm-wave signal onto the surface and decodes the backscattered signal (3). Evaluation shows the system can accurately detect metasurfaces at distances up to 5m indoors, even when non-line-of-sight or facing away, demonstrating potential for applications like spontaneous authentication and security.
Scalable Wireless ECG Streaming
This document discusses a scalable wireless ECG streaming system for continuous monitoring of patients. The system uses low-cost disposable patches that can record and wirelessly transmit medical-grade vital signs like ECG, temperature, and blood pressure for up to 48 hours on a single charge. To address the challenges of reliably transmitting ECG data from multiple users over variable wireless body area network channels, the system employs a joint source-channel coding approach that linearly encodes ECG similarities within and across heartbeats to allow for graceful degradation of the ECG signal proportional to channel errors, relaxing the link budget and conserving power. Evaluation results showed the system achieved good compression and distortion performance across different ECG morphologies while enabling scalability,

3_Igarss2011RFI.ppt
The document summarizes the approaches that NASA's Soil Moisture Active Passive (SMAP) mission will use to mitigate radio frequency interference (RFI) for its radar and radiometer instruments. For the radiometer, SMAP will use an on-board digital backend to detect and remove RFI through time, frequency and statistical analysis of the signal. For the radar, SMAP will use frequency hopping and thresholding to detect and remove RFI, with additional filtering of remaining RFI in ground processing. Studies indicate these approaches should allow SMAP to meet its requirements for RFI mitigation and soil moisture retrieval accuracy.

3. Instrument landing systems apply the principles of monopulse tracking to provide lateral and vertical guidance for aircraft during low visibility landings.
Introduction to radar
Radar was originally developed for military purposes during World War 2 to detect ships and airplanes. Scientists later discovered that radar could also detect precipitation, making it an essential tool for weather prediction. There are two main types of radar: pulse radar which uses pulse transmission to determine range and continuous wave radar which relies on the Doppler effect. Key radar components include the transmitter, receiver, antenna, and display unit. Radar systems can be classified by their primary mission as search, tracking, or weather surveillance radars. Common examples include air search radars, long range surveillance radars, and tracking radars used in aircraft.

The octagonal shaped antenna is identified as having good antenna performance overall.
Krittika.pdf
The document discusses ultra-wideband (UWB) communication and antenna designs for UWB applications. It proposes a baseline UWB antenna and single, dual, and tri-band notch UWB antenna designs using capacitively loaded loop (CLL) elements. The CLL elements create band rejections at desired frequencies like WiMAX and WLAN bands. Parametric studies show how adjusting CLL length, gap size, and distance from feed affects band rejection performance. While the tri-band design achieves multiple notches, closely spaced bands are difficult to reject due to element coupling. Measured results validate the antenna designs and characteristics.

This document summarizes research done at Lawrence Livermore National Laboratory on using 3D printing to create cellular materials with controlled architectures. It shows how printing ordered porous structures enables better control over the materials' mechanical properties compared to traditional random porous materials. In particular, it demonstrates that a "face centered tetragonal" structure exhibits different stress-strain behavior under compression and shear than a "simple cubic" structure, despite both having the same material composition and 50% porosity. This controlled architecture printing process could enable new material designs with targeted performance properties.
Green Aerodynamics by Leah Rogers
Class 8 tractor-trailers consume 12-13% of total US petroleum usage and average 5-8 mpg. A 1% improvement in fuel economy would save 285 million gallons of diesel per year, equivalent to 3 million tons of CO2 emissions reduced. Aerodynamic designs have potential to significantly reduce fuel consumption and emissions; for example, one designer achieved a 50% reduction through aerodynamics alone. Drag reduction devices for trucks are a $12 billion industry, with some paying for themselves in fuel savings within one year.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Signatures of wave erosion in Titan’s coasts
The shorelines of Titan’s hydrocarbon seas trace flooded erosional landforms such as river valleys; however, it isunclear whether coastal erosion has subsequently altered these shorelines. Spacecraft observations and theo-retical models suggest that wind may cause waves to form on Titan’s seas, potentially driving coastal erosion,but the observational evidence of waves is indirect, and the processes affecting shoreline evolution on Titanremain unknown. No widely accepted framework exists for using shoreline morphology to quantitatively dis-cern coastal erosion mechanisms, even on Earth, where the dominant mechanisms are known. We combinelandscape evolution models with measurements of shoreline shape on Earth to characterize how differentcoastal erosion mechanisms affect shoreline morphology. Applying this framework to Titan, we find that theshorelines of Titan’s seas are most consistent with flooded landscapes that subsequently have been eroded bywaves, rather than a uniform erosional process or no coastal erosion, particularly if wave growth saturates atfetch lengths of tens of kilometers.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.

Targeting Hsp90 and its pathogen Orthologs with Tethered Inhibitors as a Diagnostic and Therapeutic Strategy for cancer and infectious diseases with Dr. Timothy Haystead.The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:
