Is Lateral Entry Beneficial To Elite Swimmers? A Preliminary Study, Chen Chen, Jie Gao, Boris Bačić, Shenghao Zhou

ISBS Proceedings Archive

The purpose of this study was to improve performance of elite swimmers during the starting phase, by analysing whether the lateral entry technique is beneficial to athletes' starting. Participants’ (N=12) motion data were obtained from a 3D Performance Analysis System (Kistler 9691A1) with three cameras. Extracted 14 parameters were analysed using paired samples t-test. Differences contributing to the lateral entry performance included decrease of both entry angle and maximum depth by 1° and 0.42 m respectively (p<.01), and increase of push force by 0.08 of body weight (p<.01). The preliminary results show that the lateral technique provides a 0.06 s reduction in time to reaching the first 5 m (p<.05) compared to ordinary entry, suggesting performance improvements at start times.

ISBS Proceedings Archive

The purpose of this study was to compare the acute effect of a grip-constraint tool on upper body and racket kinematics during tennis single-handed forehand strokes. Upper-body and racket kinematics for two grip conditions, Preferred (self-selected) and Grip-constraint tool (fixed semi-western forehand grip) were captured for eleven tennis players using a 22-camera Vicon motion capture system (240 Hz). Using a grip-constraint tool resulted in a more closed racket face tilt (~4°) at ball impact while having variations in joint rotations across the shoulder, elbow and wrist. This possibly demonstrates the participant’s ability to self-organise compensatory angular rotations across the upper …

ISBS Proceedings Archive

This work is a case study observing the impact of various kinematics modifications in the simulated pressure forces and hydrodynamic work done by an athlete performing maximum effort Underwater Undulatory Swimming (UUS). The studied athlete was recorded using a Motion Capture methodology. Seven key joints were identified to represent the athlete’s motion and their position were fitted with a fourth order Fourier series. This kinematic data was then modified to reduce or amplify the upper-body and lower-body motion but also to have a linear wave propagation. The kinematics (10 in total) were inputted in an unsteady 2D Computational Fluid Dynamics …

Ball Size And Weight Effects On Throwing Kinematics And Kinetics In Youth Baseball Athletes, Charles J. Arnold, Natalie Hosmer, Miles Moore, Garrett Bullock, Kristen Nicholson

ISBS Proceedings Archive

In baseball, youth players play on smaller fields with shorter base path distance, pitching distance, and smaller mounds. Despite this, the baseball itself remains unchanged for youth athletes. This prospective cohort analyzed the kinematics and kinetics of 38 youth baseball pitchers while using modified sized and weighted baseballs. An ANOVA was used to determine statistical significance amongst ball modifications. ANOVA results show significance between the 3oz-5oz baseball with the 3oz baseball decreasing elbow varus torque. This is a preliminary study on the effects of modified baseballs on youth athletes.

Wave Attenuation Through Mangrove Forest Using Lidar Representation, Elizabeth Bogan

LSU Master's Theses

Mangrove forests can be found along the world’s intertidal tropical and sub-tropical coastlines. These forested wetlands provide many ecosystem services, including supporting coastal food chains, trapping sediment, and shoreline stabilization. Mangroves are also known for flood damage mitigation by dissipating waves and surge during flooding events. Thus, coastal communities declare a vested interest in the performance of the forest to mitigate flood damage. Physical models using artificial mangrove structures have shown that red mangrove-dominated fringe forests can protect built infrastructure by reducing wave height due to increased drag. One way to estimate the contribution of red mangrove (Rhizophora mangle) prop …

Efficient Delivery Of Biological Cargos Into Primary Cells By Electrodeposited Nanoneedles Via Cell-Cycle-Dependent Endocytosis, Zongjie Wang, Hansen Wang, Sichun Lin, Mahmoud Labib, Sharif Ahmed, Jagotamoy Das, Stephane Angers, Edward H. Sargent, Shana O. Kelley

Peninsula Medical School

Nanoneedles are a useful tool for delivering exogenous biomolecules to cells. Although therapeutic applications have been explored, the mechanism regarding how cells interact with nanoneedles remains poorly studied. Here, we present a new approach for the generation of nanoneedles, validated their usefulness in cargo delivery, and studied the underlying genetic modulators during delivery. We fabricated arrays of nanoneedles based on electrodeposition and quantified its efficacy of delivery using fluorescently labeled proteins and siRNAs. Notably, we revealed that our nanoneedles caused the disruption of cell membranes, enhanced the expression of cell–cell junction proteins, and downregulated the expression of transcriptional factors of …

Berth Allocation At Passenger Terminals Using Auctions, Dimitrios Giampouranis

Electronic Theses and Dissertations Archive

Both the industry/commercial community and academic circles have long recognized the necessity for developing an efficient and dependable system for allocating berth and quay slots at seaports. The majority of scholarly articles, however, deal with container ports, where berth allocation is often done on a first-come, first-served basis and/or based on long-term contracts. Although the berth allocation problem has been extensively studied and documented, it seems that few studies have been published with reference to auctions as the primary method of efficiently allocating berthing timeslots at passenger terminals. Previous studies have recognized the advantages that game theory and auctions have …

Designated Driver-Less Cars? Why Current Georgia Law Supports Liability For Intoxicated Drivers Of Autonomous Vehicles, Jesse L. Keeffe

Georgia Law Review

In recent years, autonomous vehicles (AVs), once the province of science fiction, have become an increasingly common sight on American roads. This new technology raises a host of novel legal questions, one of which is how driving under the influence (DUI) law should apply to AVs. Georgia has authorized the use of AVs, and some lawmakers who voted in favor of that authorization did so because, at least in part, they felt AVs could reduce the number of DUIs in Georgia. This Note argues, however, that Georgia DUI law as written and interpreted by the Georgia courts would apply to …

A More Reasonable Section 230 Of The Cda: Imposing A Pre-Defined Duty Of Care Requirement On Online Platforms, Samuel Won

Georgia Law Review

Heralded by some as the “Magna Carta of Cyberspace,” and by others as the “Law that Ruined the Internet,” Section 230 of the Communications Decency Act provides online platforms civil immunity from a wide variety of unlawful and harmful activity conducted by the platform’s users, including the publishing of harmful and hateful content. From “Zoom bombing” and orchestrated rape to malicious catfishing and image-based sexual abuse, platforms like YouTube, Facebook, and Instagram enjoy the freedom to simultaneously ignore and enable these reprehensible realities. Thus, a reexamination of Section 230’s appropriateness is long overdue, and a working solution must be critically …
