The accurate measurement of pediatric cardiac output by thermodilution requires that the quantity of cold indicator introduced into the central circulation be known. This study defines an important source of error in the correction factor for the amount of heat gained by small volumes of cold injectate during passage through pediatric catheter systems. This error may result in significant overe...

Sources of error in the estimation of ventricular volume from CAT scans are discussed and the accuracy of the measurement assessed. Two methods of calculating ventricular volume from an intraventricular injection of radioisotope are described and compared. Finally, the CAT scan and isotope methods are compared and contrasted. The error associated with a single measurement of volume by any of th...

The goal of a fault injection attack is to extract a secret key which is embedded in a cryptographic device by injecting a fault during execution of the algorithm. In particular, an attacker can extract the master key of the advanced encryption standard (AES) using only a one-byte fault injection. We propose a new countermeasure method resistant to fault injection attacks by checking the differ...

Start of fuel injection and fuel type are two important factors affecting engine performance and exhaust emissions in internal combustion engines. In the present study, a one-dimensional computational fluid dynamics solution with GT-Power software is used to simulate a six-cylinder diesel engine to study the performance and exhaust emissions with different injection timing and alternative fuels...

The main objective of this paper is to predict the warpage of a circular injection molded part based on different processing parameters. The selected part is used as spacers in automotive, transmission, and industrial power generation industries. The second goal is facilitating the setup of injection molding machine without (any) need for trial and error and reducing the setup time. To meet the...

The requirement for narrow linewidth lasers or short-loop propagation delay makes the realization of optical phase-lock loops using semiconductor lasers difficult. Although optical injection locking can provide low phase error variance for wide linewidth lasers, the locking range is restricted by stability considerations. Theoretical and experimental results for a system which combines both tec...

This paper describes the development and initial cadaver studies using a prototype image-guided surgery system for femoroplasty, which is a potential alternative treatment for reducing fracture risk in patients with severe osteoporosis. Our goal is to develop an integrated surgical guidance system that will allow surgeons to augment the femur using patient-specific biomechanical planning and in...

This paper proposes a neuro-fuzzy approach for optimizing injection molding parameter settings. The approach consists of design of experiments and neuro-fuzzy systems. Experimental data shows that the proposed approach performs better than the traditional trial and error practices usually involved in the injection molding process.

BACKGROUND The purpose of this study was to evaluate the use of intralesional propranolol injection in the management of periocular capillary hemangioma. METHODS A prospective study was performed in 22 consecutive patients with periocular hemangioma. Twelve patients underwent intralesional propranolol injection and ten patients underwent intralesional triamcinolone injection. The size of the ...
