In this study, the recall accuracies for different keys on a keyboard were studied and analyzed in a systematic way. It was found that alphabetic keys in the area of "Typing Keys" resulted in relatively lower recall accuracies than "Function Keys", "control Keys" and "Numeric Keys". Besides, there was an absence of significant association between the relative use frequency of English letters and their recall accuracies, confirming to the general expectation that typing tasks rely on the processing of implicit memory rather than explicit memory. Regarding the recall accuracies for numeric keys, participants had higher recall accuracy for the keys located in "Numeric Keypad" than those in the "Typing Key" area. This might be the result of experience transfer from their daily interaction with devices of similar layout (ATM). Some useful suggestions were provided for the design of a more user-friendly keyboard layout.

In this paper an improved method is proposed to convert multi-variable dependent time-varying systems into a polytopic representation with uncertain parameters for further stability *** on the Taylor expansion,the employed technique utilizes a specific arrangement of the cross-variable terms such that the obtained vertices of the polytopic system increases only polynomially with the order of the Taylor *** example about stability analysis demonstrates the effectiveness and usefulness of the proposed method in robust stability studies.

An improved diagnosis method of technological systems is proposed in this paper that is based on their qualitative colored Petri-net model (Leitold et al. 2014). The proposed diagnosis method can be used when more than one fault occur in the system and if the fault evolves during the operation of the system. In order to make the diagnosis of complex process systems computationally feasible, a structural decomposition method is introduced to reduce the size of their occurrence graphs and to make the diagnosis easier. The proposed methods are illustrated on examples.

The true-fake detection of Chinese liquors can be considered as a one-class classification problem. Using only positive sample in training process brings about difficulties in determining the optimal parameters of one-class SVM and its kernel. And one-class SVM optimized with conventional grid search method has a low recognition rate of positive test samples. Hence, we proposed a new idea for recognition, namely boosting-based one-class SVM. Six different kinds of liquors were sampled by a self-designed electronic nose system. After the preprocessing and feature extraction of sample data, 18 groups of optimum parameters of one-class SVM were chosen from specified parameter range, each group was used to train a classifier with training algorithm. Then the true-fake decisions were made for test samples with boosting integration rules. Finally the recognition rates of Hongjinjiu and Lanjinjiu positive sample reached 95.24% and 100%, and the recognition rates of both positive and negative sample reached 97.04% and 94.83%, respectively.

We designed a portable electronic nose (e-nose) for rapid detection of Chinese liquors. The e-nose had an evaporation chamber wrapped with silicone heating band, which could vaporize the liquor samples in 1 minute. The sequential sampling and clean-out lasted 100 seconds and 3 minutes, respectively. Hence, one fast detection process could be finished within 3 minutes without regard to clean-out. In order to acquire enough information from array's sampling curves for classification, we chose 60 features (including 6 features per sensor) according to the response curves, the derivative of the response curves and the relative change rate curves of conductivity. Then the dimension of features was reduced by principle component analysis (PCA). Finally, classification of Chinese liquors was performed using C-Support Vector Machine (C-SVM) and the classification rate was 96.7%.

9th IFAC Symposium on Fault Detection, Supervision and Safety for Technical processes, SAFEprocess 2015

作者： Pfeffer, Annett Urbas, Leon Department of Process Control Systems Engineering Technische Universität Dresden Germany

As an approach to cope with rising volatility of sales markets and increasingly shorter development cycles, process industries are expecting much from the concept of modularization. However, a topic that is still rarely focused in this context is safety. Therefore, this paper is focused on the expected challenges of engineering functional safety including the architectures of safety instrumented systems, and the requirements of modularization. Possible architectures are presented and discussed in relation to the requirements of functional safety in modular process plants. © 2015, IFAC (International Federation of Automatic control) Hosting by Elsevier Ltd.

The optimization of the operation of chemical plants may require the development of mathematical models of the process units of a plant. These mathematical models can be either first-principles or data-driven models. The former type of modeling may be complex for the use in optimization and especially for online applications such as real time optimization. Available measured process data can be used to develop the latter type of modeling. Although data-driven models offer several benefits for online applications, there are some very significant challenges related to their development in a practical industrial implementation. This paper discusses the important aspects of the building of data-driven models and demonstrates the effects of these types of models on the optimization results. The current work demonstrates the application of a real time optimization framework applied to an industrial air compressor station of an air separation plant when the models are based on operating data.

A study of the optimal real-time management of hydrogen H_2 networks in an oil refinery has been carried out. The paper addresses the main problems related to the operation of the networks combining data reconciliation with a real-time optimization RTO system for the optimal production and redistribution of hydrogen. Coherent and robust results have been achieved regarding the data reconciliation stage despite all the uncertainty in measurements and process operation, according to the off-line validation performed. Once the network state has been estimated, a RTO approach was followed aiming at the real-time optimal operation of the global refinery H_2 network;an analysis of the solutions achieved was also performed.

Globally stabilizing state feedback control design for Lotka-Volterra systems based on underlying linear dynamics

IFAC-PapersOnLine 2015年第11 11期48卷 1000-1005页

Using translated X-factorable phase space transformations and nonlinear variable transformations a dynamically similar linear ODE model is associated to the Lotka-Volterra system models with a positive equilibrium point. This enables to use a linear full state feedback controller to stabilize the system in controllable cases, that leaves the open loop equilibrium point unchanged. The linear state feedback controller design problem in the general case has also been formulated to ensure the compartmental property of the closed loop system from which the existence of a diagonal Lyapunov function follows. Further extension has been obtained by using the time re-parametrization transformation defined for quasi-polynomial models. © 2015
