Proposed testing method for foam padding
One very basic necessity for foam padding testing technology is the ability to test two different padding samples and compare the results. The current standard for testing is to use a steel anvil backing for the padding, create an impact and record the parameters of the collision. The standardized …

Analysis of airline schedule padding on U.S. domestic routes
… how some of the above factors affect carriers' padding and their on-time performance. The results indicate distance and time of day to be the most important factors that affect schedule padding. While absolute buffer increases with distance, when buffer is measured as a fraction of nominal block …

Head Impacts in Hockey and Youth Football: Biomechanical Response and Helmet Padding Characteristics
… absorbing properties of three different helmet padding technologies. The body of work is aimed at increasing understanding of head impact and concussion and the ability of existing helmet technologies to prevent these injuries with a goal of reducing the occurrence of injury.

Composite materials in dynamic shipboard structural mounts
… metal structural and machinery mounts with padding made of composite material. The two types of padding or isolation materials are represented by steel and CFRP (carbon fiber reinforced polymer). Machinery and instruments in ships are often mounted for two main reasons: they create unwanted …

Data Acquisition for Domain Adaptation of Closed-Box Models
… we propose to acquire extra data to construct a "padding" model to help the original closed box with its classification weaknesses in the target domain. Our solution consists of a "weakness detector" to discover the deficiency of the original closed-box model and the Augmented Ensemble approach to …

GRAND-assisted Optimal Modulation
… practical system for OM that uses only a simple padding scheme instead of the complex mechanisms in the current literature. A guess-based error correction demodulator lies at the core of the proposed system. Together with the padding scheme of our choice, our novel light-weight variant of …

Mitigating Concussion: An Innovative Football Helmet
… energy absorbing materials including the foam paddings (used in current helmets). Additionally, alternative designs are proposed. A new padding structure has beenivdeveloped and tested in a football helmet. The impact performance of an off the shelf helmet is compared to the proposed design. …

Measuring the impact of site configurations on site fingerprinting over the web and Tor
… are served. Additionally, we experiment with padding site sizes, renaming site resources, and hosting sites from both single and multiple servers in order to observe the effect of each of these changes on fingerprinting accuracy. In order to collect traces from sites that reflect our …

Football Shoulder Pad Design and Its Effect on Head Kinematics in Shoulder-to-Helmet Impacts
… on the struck head kinematics. Additional padding was added to a shoulder pad as means to reduce the overall stiffness of the system, and an unmodified shoulder pad acted as the control. Participants performed a series of impact tests with two shoulder pad variations to identify if …

Optimization of new semi-automatic TIG welding process for surface quality through taguchi method
… project. Samples are produce in single bead and padding bead on top of substrate (base metal) in horizontal position. Substrate material is from Mild Steel AISI 1018 while wire filler ER70S-6 has a diameter of 0.8 mm and Tungsten electrode EWth-2 (2% Thorium, Red) has a diameter 2.4mm. Argon is …

Refining inferred road maps using GANs
… improve its realism. We show that adding a truth padding stage between the discriminator and generator vastly improves tile consistency, and we introduce a postprocessing pipeline to further clean the graph. To evaluate these results, we focus on a state-of-the-art map inference method known as …

Design of a 3-D rapidly scanning laser Doppler velocimeter with low SNR signal processing
… for frequency counters. The FFT with zero-padding and log parabolic fit provides frequency estimates with RMS error below 1 % for signals with SNR above -5 dB. To obtain frequency estimates for signals with SNR below -5 dB, the FFT with zero-padding and parabolic lit must be used, signals …

Verifying Hardware Security Modules With True Random NumberGenerators
… functions for generating keys, creating nonces, padding, and more. This thesis presents a definition of Information-Preserving Refinement with Randomness (IPRR) that captures the idea that a HSM with a TRNG is correct and is secure from timing side channel attacks. We additionally construct a …

Handling Invalid Pixels in Convolutional Neural Networks
… However, pixels added to the input through padding result in adding extra information that was not initially present. This extra information can be considered invalid. Invalid pixels can also be inside the image where they are referred to as holes in completion tasks like image inpainting. …

Preventing encrypted traffic analysis
… traffic analysis focus on re-routing and padding. These prevention techniques have considerable resource and overhead requirements. Furthermore, padding is easily detectable and, in some cases, can introduce its own vulnerabilities. To address these shortcomings, we propose embedding real …

Evolution of loosely synchronized spreading codes in code-division multiple-access systems
… These strings of zeros are known as internal padding.<br/><br/>One of the advantages normally claimed for CDMA systems is resistance to eavesdropping and jamming. It might appear at first sight that the structure of LS codes is rather predictable in comparison with codes constructed using …

Optimal deadrise hull analysis and design space study of naval special warfare high speed planning boats
… at the hull-deck and deck-seat interfaces (deck padding and suspension seats, for example). The object of this thesis is to develop an Optimal Deadrise Hull (ODH) that reduces mechanical shock where it first enters the boat, at the hull-sea interface. Planing boat hydrodynamics were reviewed and …

Energy-Efficient Hardware Architectures for Enhanced Secure Communication Systems
… Additionally, this research repurposes the padding bits of AES to improve error correction capabilities, thereby enhancing the reliability of data transmission across noisy channels. Together with the application of the Guessing Random Additive Noise Decoding (GRAND) decoder, these …

Scanning-free compressive reconstruction of object motion with sub-pixel accuracy
… holography. Together with spectrum domain zero-padding, our compressive algorithm allows for sub-pixel accuracy edge localization. The extension to the 2D case is not trivial. It has been shown that the spiral phase mask can serve as an approximate 2D derivative operator in the Fourier domain. …
