Intel’s newly-announced low-cost and high precision RealSense 3D (RGBD) camera is becoming ubiquitous in laptops and mobile devices starting this year, opening the door for new applications in the mobile health arena. In this paper, we demonstrate how the Intel RealSense 3D camera can be used for low-cost gaze tracking and passive pulse rate estimation. We develop a novel 3D gaze and fixation t...

Mining projects especially relating to limestone deposits require an accurate knowledge of tonnage and grade, for both short long-term planning. This is often difficult establish as detailed exploration operations, which are required get the description deposit, costly time consuming. Geologists mining engineers usually make use geometric geostatistical methods, estimating grade ore reserves. H...

What is the role of fraction magnitude knowledge in learning fraction addition? An experiment with 71 6th and 7 grade students compared fraction addition instruction and practice with a magnitude representation to a tightly controlled nonmagnitude condition. In the magnitude condition, students with better fraction magnitude estimation skills benefitted more from the conceptual instruction and ...

In this paper, a genetic algorithm (GA) based principal component selection approach is proposed for production performance estimation in mineral processing. The approach combines a modified GA with principal component analysis (PCA) in order to improve the estimation accuracy of production performance. In this context, the extended chromosome encoding, the fitness function formed by combining ...

BACKGROUND Current ventral hernia repair risk estimation tools focus on patient comorbidities with the goal of improving clinical outcomes through improved patient selection. However, their predictive value remains unproven. METHODS Outcomes of patients who underwent midline ventral hernia repair with retrorectus placement of mid-weight soft polypropylene mesh between 2010 and 2015 were retro...

OBJECTIVES Recent studies have suggested that postoperative complications could have a potential negative effect on long-term outcome after oesophagectomy for cancer. Because respiratory failures represent the most frequent postoperative complication, we have investigated the prognostic impact of these complications on disease-free survival (DFS). METHODS From a prospective single-institution...

PURPOSE To examine the relationship between low perceived chances for success in life and binge drinking in a sample of economically disadvantaged, predominantly minority, urban adolescents. METHODS A sample of predominantly black and Hispanic students (N = 774) from 13 inner-city schools completed confidential questionnaires in the 7th, 8th, and 9th grades. Eight items measured students' est...

PURPOSE To investigate the risk factors for appendiceal metastasis of epithelial ovarian cancer and compare findings with the previous studies. MATERIALS AND METHODS One hundred and thirty-four patients with epithelial ovarian cancer were assessed in this study. All of them had undergone a surgical procedure including appendectomy. Of these, 21 (15.7%) patients who had appendiceal metastasis ...

alloy steel, which is versatile in such qualities as grade, property and application, can play an important role in the technical and economic development of the country. the present consumption of the key industrial sector to this strategic material, specified basically as semi- finished products exceeds 100,000 tons per year. however, a rough estimation of the true potential needs, does clear...

OBJECTIVES Open radical nephroureterectomy (O-RNU) has been the gold standard for the treatment of upper urinary tract urothelial carcinoma (UUT-UC) for decades. With the advances in laparoscopic techniques and endourologic procedures, this concept has been increasingly challenged. Oncologic outcome prediction is mainly based on stage and grade. With progress in medical treatment, adjuvant ther...
