The present study describes the development and initial validation of a new obesity-specific, self-report measure of health-related quality of life (HRQOL) for children aged 5-13 years. Participants included 141 obese children (mean age=9.2 years, 67% female, 55% black, mean zBMI=2.52) and their primary caregivers. Children completed Sizing Me Up (obesity-specific HRQOL) and the PedsQL (generic...

Conventional methods for optimal sizing of wires and transistors use linear RC circuit models and the Elmore delay as a measure of signal delay. If the RC circuit has a tree topology the sizing problem reduces to a convex optimization problem which can be solved using geometric programming. The tree topology restriction precludes the use of these methods in several sizing problems of signi cant...

This study proposes a gradient-free approach to integrated circuit sizing that takes into account the statistical variations of device parameters and ranges of operating conditions. A novel gradient-free algorithm for solving the worst-case performance problem is proposed. The proposed algorithm produces corners that are used in the optimisation loop of the circuit sizing process. The set of co...

BACKGROUND Accurate preoperative assessment of the aortic annulus dimension is crucial for successful transcatheter aortic valve implantation (TAVI). In this study we examined the accuracy of a novel method using two-dimensional transesophageal echocardiography (2D-TEE) for measurement of the aortic annulus. METHODS We evaluated the theoretical impact of the measurement of the annulus diamete...

This paper presents a mathematical model for estimating the optimal sizing and assessing standalone hybrid power system's performance entirely based on variable renewable energy sources coupled with storage system. study evaluates how different levels of main components' capital cost loss supply probability would affect sizing. The case selected this was Ometepe Island in Nicaragua, where crate...

A new method for detection and sizing of closed crack is described which uses transient waveform of subharmonics with half input frequency in ultrasonic nondestructive evaluation. In analogy to the resonant characteristics of vibration of bubbles in liquids, we formulate an equation for resonant excitation of subharmonics at partially closed cracks. The equation has been partially verified by c...

Although many design tools have been developed for digital design, analog design tools are only just being introduced. This paper presents a new optimization method for automatically sizing the circuit topology of analog cells. This method minimizes a cost function, which depends on a set of designer specifications. It employs the tabu search heuristic to avoid being trapped in a local minimum ...

Abstrac t-Based on an incremental path search algorithm, this paper addresses the problem of performance driven path classification by sizing selected gates on the shortest and the longest identified paths of the circuit. Delay and power/area constraints are managed using circuit path sizing alternatives defined through a realistic evaluation of gate power and delay. Implemented in the POPS too...

Technetium-99m sulfur colloid ( mTc-SC) has been useful in reticuloendothelial imaging, and in particular in liver/spleen and more recently bone marrow scintigraphy. Technetium99m SC can also be employed to localize acute gastrointestinal bleeding and has been used in lung ventilation studies. The standard radiolabeling method requires a heating period in a boiling water bath. A comparison of a...
