The objective of this study is to upgrade the operation of conventional activated sludge treatment plants for the purpose of saving aeration energy and at the same time providing better utilization of existing plant capacity for nutrient removal without major investment. In this study, pilot-scale experiments of the single stage activated sludge process (ASP), as operated in existing ASP in sou...

Colorectal cancer is one of the leading causes of cancerrelated mortality in the world, although it can be efficiently treated if detected early. Colonoscopy is the most-commonly adopted visual screening procedure of the colon by means of a flexible tiny endoscopic camera. In an effort to promote early screening and to facilitate mastering the endoscope motion by the physician, teleoperable rob...

In this work we propose a simultaneous scheduling and control optimization formulation to address both optimal steady-state production and dynamic product transitions in multiproduct parallel continuous stirred tank reactors. The simultaneous scheduling and control problem for multiproduct parallel continuous reactors is cast as a Mixed-Integer Dynamic Optimization (MIDO) problem. The reactor d...

N-dimensional surfaces are defined by the tensor product of B-spline basis functions. To estimate the unknown control points of these B-spline surfaces, the lofting method also called skinning method by cross-sectional curve fits is applied. It is shown by an analytical proof and numerically confirmed by the example of a four-dimensional surface that the results of the lofting method agree with...

Simultaneous interpretation is a complex cognitive task that not only demands multilingual language processing, but also requires application of extreme levels of domain-general cognitive control. We used MRI to longitudinally measure cortical thickness in simultaneous interpretation trainees before and after a Master's program in conference interpreting. We compared them to multilingual contro...

background: there is a great concern for the possible adverse effects of radiofrequency radiations of cell phones. moreover, unwanted sound is one of the physical pollutants of current societies. thus, the present study was conducted to examine the effect of cell phone waves, sound, and simultaneous effect of cell phone waves and sound on sperm viability and total antioxidant capacity of blood ...

One of the critical components of mapping an unknown environment is the robot’s ability to locate itself on a partially explored map. This becomes challenging when the robot experiences positioning error, does not have an external positioning device, nor the luxury of engineered landmarks placed in its free space. This paper presents a new method for simultaneous localization and mapping that e...
