Three-Dimensional Body Volume Measurement From Two-Dimensional Images: Towards A Smartphone Application
… scanners provide a useful tool to provide body measurements based on 3D images in obesity management. However, such scanners are often inaccessible due to cost. A smartphone image-based method able to produce 3D images may provide a more accessible measuring tool. As a step towards developing …

Pilvinės aortos aneurizmos automatinės detekcijos nauda matuojant aneurizmos tūrį. Literatūros apžvalga ir modelio sukūrimas /
… Despite its widespread use, diameter measurement has some relevant limitations. Therefore, aortic aneurysm volume measurement has recently been reported as a superior and more accurate method than diameter. Although volume measurement excels in detecting aneurysm sac changes …

Body composition analysis using air displacement plethysmography
… the density of an object by measuring the volume of air the object displaces as well as the objects mass. A principle assumption of this approach is the validity of the two Component Model of body composition (2C Model). The model states that the human body can be split into two components …

High precision mass-based assay to examine growth regulation of the cell cycle
… to be a fundamental property of cell state, its measurement on a single-cell basis with high-resolution has been elusive primarily due to enormous experimental barriers. This thesis discusses the use of a cantilever based suspended microchannel resonator (SMR) to measure mass, and resistive pulse …

Development of Advanced Image Processing Algorithms for Bubbly Flow Measurement
An accurate measurement of bubbly flow has a significant value for understanding the bubble behavior, heat and energy transfer pattern in different engineering systems. It also helps to advance the theoretical model development in two-phase flow study. Due to the interaction between the gas and …

Point cloud alignment in arm reconstruction for lymphedema detection by iterating pairwise ICP
… This thesis describes a system for measuring arm volume with the goal of providing a cost-effective, reliable, easy to use, comfortable, and informative alternative to the tedious water displacement method or the expensive perometer. The device consists of 8 inexpensive positionally fixed …

The Role of Three-dimensional Ultrasound in the Diagnosis and Treatment of Uterine Pathology
… of uterine pathology. We performed serial measurements of fibroids over a period of time to examine their natural history. We found that fibroids tend to grow at a relatively fast average rate in pre-menopausal women, which is influenced by the initial fibroid volume and patients’ …

A plethysmographic device for determining human body volume and body density
The measurement of total body volume (V) (excluding lung volume) together with total body mass (m) is required in order to determine body density (d = m/V). From this, and using certain simplifying assumptions, it is possible to derive body composition in terms of fat mass (FM) and fat free mass …

Gastro-duodenal motility & nutrition in the critically ill.
… this lack of success was large gastric residual volumes, indicative of delayed gastric emptying (GE). This study, accordingly, quantified the limitations of nutritional delivery in contemporary practice in a local ICU. The results suggest that a better understanding of the pathogenesis underlying …

Knowledge discovery with recommenders for big data management in science and engineering communities
… from both the infrastructure perspective (i.e., measurement recommender) and the applications perspective (i.e., topic recommender and scholar recommender). In the infrastructure perspective, we identify and diagnose network-wide anomaly events to address performance bottleneck by proposing a …
