Low-overhead distributed transaction coordination
… significantly reducing transaction coordination overhead. Granola supports general atomic operations, enabling it to be used as a platform on which to build various storage systems, e.g., databases or object stores. We introduce specific support for independent transactions, a new type of …

EFFECT OF UPPER BODY FATIGUING EXERCISE ON SHOULDER DYNAMIC STABILITY IN OVERHEAD AND NON-OVERHEAD ATHLETES
<p>Overhead athletes may be at an increased risk for shoulder injury if fatiguing exercise results in reduced shoulder dynamic stability. The purpose of this study was to determine the effect of upper body fatiguing exercise on shoulder dynamic stability of overhead athletes and non-overhead …

Overhead management guide for aerospace procurements
… focuses on the management emphasis concerning overhead cost control. Senior personnel within the Naval Air Systems Command (NAVAIR) review a multitude of cost information. Due to the nature and complexity of these costs, it is extremely difficult to analyze and interpret cost data and, more …

Anti-swing control of overhead cranes
Overhead cranes are widely used for transporting large and heavy suspended objects such as shipping containers. Acceleration and deceleration of the crane generally induce swinging motion in the suspended payload. A method is presented to find the trajectory for an overhead crane that will ensure …

Performing overhead tasks with supernumerary robotic limbs
Overhead tasks such as those frequently found in aircraft manufacturing pose health risks to the workers due to the strain imposed on the shoulders. To reduce the risk of injury, a set of supernumerary robotic limbs (SRL) were designed to perform these overhead tasks. The SRL is designed with …

Pose estimation using overhead imagery and semantics
… been captured through satellite imagery. These overhead images contain useful information that can aid with outdoor robot navigation and localisation, by, for example, being used as prior maps in a localisation pipeline. This thesis presents a method for generating semantically consistent robot …

Compiler Optimization Techniques for Scheduling and Reducing Overhead
… execution time, decrease in address arithmetic overhead, access to data in registers as opposed to caches, etc. With the advent of VLIW processors, the exploitation of fine-grain instruction-level parallelism has become a major challenge to optimizing compilers. Fine-grain scheduling of inner …

Analysis of scapulothoracic muscle recruitment in overhead athletes
Chronische schouderklachten komen frequent voor bij atleten die een bovenhandse sport beoefenen. Tijdens de bovenhandse slag-, werp-, of zwembeweging wordt de schouder immers aan extreem hoge belastingen onderworpen, die de integriteit van de capsuloligamentaire structuren en de stabiliteit van het …

Reducing exception management overhead with software restart markers
… substantially reduce the exception management overhead found in precise exception implementations, and enable the use of new architectural features that might be prohibitively costly with conventional precise exception implementations. Additionally, software restart markers can be used to …

Low-overhead scheduling for improving performance of scientific applications
… its impact to data movement and synchronization overhead. We developed a series of scheduling strategies that mitigate imbalances without incurring high overhead. Our strategies provide performance gains for various HPC codes, and perform better than widely known scheduling strategies such as …

A semi-blocking checkpoint protocol to minimize checkpoint overhead
… protocol to hide the checkpoint overhead by overlapping global checkpoint with applications. To further analyze the benefits of using semi-blocking checkpoint protocol in case of failures, we extend Daly’s model and show the usefulness of the semi-blocking protocol for different …

Achieving Secure and Performant Databases with Minimal Resource Overhead
… running the VMs can minimize the CPU/memory overhead per VM while also improving security for the DMBS. Overall, these changes allow cloud-hosted machines to more efficiently utilize resources.

Towards constant bandwidth overhead integrity checking of untrusted data
… operations increases, the scheme's bandwidth overhead approaches a constant bandwidth overhead. The trace-hash scheme, intuitively, maintains a "write trace" and a "read trace" of the write and read operations on the untrusted data. At runtime, the traces are updated with a minimal …

Low-Velocity Impact to High-Temperature Low-Sag Overhead Conductors
<p>High-Temperature Low-Sag (HTLS) conductors, such as Aluminum Conductor Composite Core (ACCC), improve infrastructure to support the delivery of power to meet the nation's increasing demand for electricity. Their response to low-velocity impacts during transportation, installation or in service, …

Channel Estimation Overhead Reduction for Downlink FDD Massive MIMO Systems
… suffer significantly from the channel estimation overhead. In this thesis, we propose a minimum mean square error (MMSE)-based channel estimation framework that exploits the spatial correlation between the antennas at the BS to reduce the latter overhead. We investigate how the number of antennas …
