Whey is an abundant by-product of cheese production process and it is considered a special waste due to its high nutritional load and hypertrophic potential. Technologies for whey valorization are available. They can convert such waste into high-value products, like whey proteins. However, the remaining liquid (called permeate) is still considered as a polluting waste due to its high lactose concentration. The alcoholic fermentation of lactose into ethanol will simultaneously achieve two important goals: safe disposal of a pollutant waste and green energy production. This methodology paper illustrates the workflow carried out to design and realize an optimized microorganism that can efficiently perform the lactose-to-ethanol conversion, engineered via synthetic biology experimental and computational approaches.

Aim: To investigate the underlying relationship between obesity and the extent of emphysema depicted at CT. Methods and materials: A dataset of 477 CT examinations was retrospectively collected from a study of chronic obstructive pulmonary disease (COPD). The low attenuation areas (LAAs;≤950 HU) of the lungs were identified. The extent of emphysema (denoted as %LAA) was defined as the percentage of LAA divided by the lung volume. The association between log-transformed %LAA and body mass index (BMI) adjusted for age, sex, the forced expiratory volume in one second as percent predicted value (FEV1% predicted), and smoking history (pack years) was assessed using multiple linear regression analysis. Results: After adjusting for age, gender, smoking history, and FEV1% predicted, BMI was negatively associated with severe emphysema in patients with COPD. Specifically, one unit increase in BMI is associated with a 0.93-fold change (95% CI: 0.91-0.96, p < 0.001) in %LAA;the estimated %LAA for males was 1.75 (95% CI: 1.36-2.26, p < 0.001) times that of females;per 10% increase in FEV1% predicated is associated with a 0.72-fold change (95% CI: 0.69-0.76, p < 0.001) in %LAA. Conclusion: Increasing obesity is negatively associated with severity of emphysema independent of gender, age, and smoking history. © 2015 The Royal College of Radiologists.

Quantized kernel least mean square (QKLMS) algorithm is an effective up-to-date adaptive nonlinear learning algorithm which also has good performance for kernel structure growing control. It achieves good results under Gaussian noise environment. In this paper, a new algorithm, quantized kernel least mean mixed norm (QKLMMN), is proposed for adaptive nonlinear learning with non-Gaussian additive noise statistical distribution models (including combination). As an alternative of conventional squared error criteria, mixed-norm criteria is utilized for our algorithm. A comprehensive convergence analysis is carried out. Experiments for nonlinear time series prediction and nonlinear system identification are conducted. Experimental results verified the effectiveness and superiority of our proposed algorithm compared with other kernel based adaptive nonlinear learning algorithms under non-Gaussian noise environment.

In this paper, a novel watermarking scheme is proposed by embedding a gray-scale watermark into gray-scale images. The proposed scheme is a Hybrid watermarking algorithm based on singular value decomposition (SVD) and Steerable Pyramid (SP) wavelet transform. The robustness of the proposed method is evaluated by executing various image processing attacks. Peak signal to noise ratio (PSNR) is used to examine the image quality before and after the embedding process. Experimental results show that the proposed watermarking scheme is robust against various attacks.

When more and more people integrate Social Network Services (SNS) into their daily life, digital native students were more accustomed to communicate via SNS. Research shows SNS is beneficial to some academic goals, but research also shows most teachers hesitate about adopting SNS to assist teaching. Comparing to why should we integrate SNS into education, teachers are more interested in how to integrate SNS into education. In this study, two fomal college class students(N= 120) are examined the possible situation of praticing facebook assisted teaching may encounter. We found that even with the high information exchanging frequency made by facebook notification features, it's still hard to increase students' interaction without course interaction strategy. We also found the potential of creating issue group instead of class group to continue subject learning between students and alumni. © Springer-Verlag Berlin Heidelberg 2013.

The following article describes a senior engineering project design of a completed cost benefit analysis and a demonstration prototype. The project evaluates the potential energy savings of interrupting power to a hot water tank and builds a demonstration prototype as an initial proof of concept. The demonstration prototype uses a microcontroller, sensors, and solid state relay to interrupt power during low usage periods of a residential hot water tank to reduce energy consumption. A cost benefit analysis addresses the results, potential savings, and future enhancements.

World Congress on Intelligent Control and Automation (WCICA)

作者： Ning Ding Tao Chen Peter B. Luh Hui Zhang Center for Intelligent and Networked Systems Tsinghua University Beijing China Department of Electrical and Computer Engineering University of Connecticut Storrs Connecticut USA Institute of Public Safety Research Tsinghua University Beijing China

Many countries, such as the US, China, and the UK, have considered using safe elevators (such as fire elevators) on safe floors (such as refuge floors) in high-rise buildings to speed up emergency evacuation. However, for safety reasons such as sheave traction and brake capability, elevators are designed not to operate when overloaded. Overcrowding, then, may actually slow down building evacuation when a car is overloaded. As a result, how to speed up elevator evacuation considering potential overcrowding is an important issue. This problem is difficult because of the uncertain traffic and complicated elevator scheduling. To reduce the traffic uncertainties, one trend is to use the surveillance cameras in smart high-rise buildings to know the number of waiting evacuees. To avoid the phenomenon of elevator overloading, multiple elevators will be sent to the same floor based on the number of waiting evacuees. To reduce the complication of elevator scheduling, all the elevators are divided into groups with one or more elevators in each group. Then these groups will be dispatched to different floors according to the numbers of waiting evacuees. Our objective is to minimize the evacuation time with the constraints of evacuees' safety. The Genetic Algorithm toolbox in Matlab is used to solve this problem. A case study is used to demonstrate that, compared with the building where one floor can be served by one car, our elevator scheduling can reduce the evacuation time.
