Treatment of renal cell carcinoma (RCC) using ablation techniques is becoming increasingly common as a means for preserving renal function in poor surgical candidates. Despite concerns related to renal insufficiency, which is common in patients with renal disease, the current standard for imaging surveillance following ablation remains contrast-enhanced CT or MRI. Contrast-enhanced ultrasound (CEUS)...
Summary In Canada, prostate cancer is the most common male malignancy and the third most common cause of cancer death in males. Within a publicly funded healthcare system, government guidelines do not support prostate cancer screening with prostate-specific antigen (PSA), despite national primary care and specialist groups taking a more favorable position. Current surveys among patients and physicians...
Any small defect is not permitted in the industry, so PLC real-time engine performance is very important for industry robot control system. Because these industrial characteristic, a new untested system can't be used in real field.
We demonstrate the scattering superlens using elastic scattering to obtain sub-diffraction resolution. Scattering from disordered nanoparticles enables to reconstruct the sub-wavelength image of the target through time-reversal and transmission matrix.
We have developed an ontology based framework that evaluates compatibility between processing modules within an end user development framework, using MIT Lincoln Laboratory's Composable Analytics environment [1] as a test case. In particular, we focus on inter-module semantic compatibility as well as compatibility between data and modules. Our framework includes a core ontology that provides an extendible...
The structural rigidity of the ITER Thermal Shield (TS) has been verified by structural analysis. In this paper, the analysis process, methodology and demonstration of the structural integrity for the TS are described. The analysis are performed for the TS global model and detailed model such as supports and joints. TS joints in the shell model are modeled using orthogonal material properties, because...
This contribution evaluates a new Beta-less Instantaneous Cornering Stiffness (ICS) estimation scheme. It relies on the availability of the lateral tire forces measurement which in near future can be realized with economic (low cost) sensors. The estimation is only available if the change in the tire slip angle is profound enough as it is not the case during constant cornering. However, as it is shown...
This paper presents roll stability control methodology for future personal electric vehicles with 4 wheel steering system and lateral force sensors. Direct roll moment control is realized by 4 wheel steering control based on lateral tire force control. In this paper, the lateral tire force, obtained from novel lateral force sensors, was utilized to estimate a roll angle and to control the vehicle...
This study uses quantitative ultrasound techniques to investigate the possibility of monitoring changes in cervical microstructure with acoustic backscatter. Standard ??general imaging?? ultrasound transducers and a novel endocavity transducer were used to detect changes in the power spectrum of the ultrasonic backscattered echo signal as a function of the angle between the acoustic beam and the dominant...
Cleft lip is a congenital deformity condition with separation of the two sides of the lip and causes nose deformity. Evaluation of surgical corrections and assessment of prognosis in nose deformity depend mainly on doctor's subjective judgment. Development of an objective assessment tool in evaluation of the cleft lip nose deformity patients will help in advancement and evaluation of surgical techniques...
This paper aims to investigate the magnetic and electrical properties of magnetic tunnel junctions with MgO barriers. The magnetoresistance of the junction is measured at 0.4 V. Results show a magnetoresistance of almost the same values at varying radical oxidation time and Mg thickness. It is also confirmed in this study that the MgO formed by radical oxidation of Mg shows high magnetoresistance...
This paper presents a simplified unbalanced force calculation for switched reluctance machines (SRM) developed based on an electromagnetic circuit model (EMC). Derived from the EMC model, a set of analytical equations for predicting the rotor unbalanced force is achieved as functions of design parameters, which directly provides an intuitive relationship between estimated unbalanced force and design...
