“This study presents a new automated system for inspecting markings on surface mounted devices (SMDs) prior to packaging. In proposed design, marking region is identified using a normalized cross-correlation template-matching scheme. A multi-resolution pyramid image processing approach is
used to enhance speed of search process. Target image is filtered using selleck kinase inhibitor a hybrid digital logic filter (DLC) / mean and standard deviation gray scale (MSDGS) algorithm for noise filtering, Individual characters in marking arc segmented and fed to a neural network for automatic recognition. DLC / MSDGS filtcrin scheme is found more straightforward and far more robust towards a noise filtering than conventional image processing schemes. System achieves a recognition rate of 99.14% with identifying each IC chip marking within
0.05 sec. System provides an ideal solution for real-time inspection of IC markings in high-throughput SMD packaging applications.”
“Chronic thromboembolic pulmonary hypertension (CTEPH) is a progressive disease characterized by increased pulmonary vascular resistance resulting in pulmonary hypertension and right heart failure. The six-minute walk test (6MWT) distance is associated with the prognosis of CTEPH patients. Speckle tracking echocardiography (STE) is a reliable method for determining ventricular function. The aim of this study was to assess and compare the right ventricular (RV) function JNK inhibitor supplier of CTEPH patients according to their 6MWT distances. Forty-nine consecutive CTEPH patients Selleckchem DMXAA (mean age, 50 +/- 16 years; 22 male) who were referred to our center for pulmonary thromboendarterectomy (PTE) were included in the study. All patients underwent the 6MWT and right heart catheterization (RHC). Standard echocardiography and STE were performed on all patients before PTE. Patients were divided into two groups based on their 6MWT distance being less or more than 300 m. Patients with a shorter 6MWT distance had a significantly larger RV, while they had a significantly lower RV fractional area change and higher myocardial performance index suggesting impaired
RV function. Both RV basal-lateral strain and strain rate measures were significantly lower in patients with shorter 6MWT distances than those with longer 6MWT distances. Similarly, they had lower RV basal-septal, mid-lateral, and global strain measures. 6MWT distances were correlated with RV basal-lateral and mid-lateral strain measures (r = 0.349, p = 0.025 and r = 0.415, p = 0.008, respectively). Our data suggest that RV myocardial deformation parameters are associated with 6MWT distances. Determination of RV dysfunction by STE may be helpful in identifying patients with a poor prognosis.”
“Patients that present with multiple primary malignant neoplasms are increasingly encountered, but the treatment of such patients presents specific challenges and long-term survival is rare.
