The JFK Coma Recovery Scale-Revised (JFK CRS-R), a behavioral scale, is often used for clinical assessments of patients with disorders of consciousness (DOC), such as patients in a vegetative state. However, there has been a high rate of clinical misdiagnosis with the JFK CRS-R because patients with severe brain injures cannot provide sufficient behavioral responses. It is particularly difficult to evaluate the communication function in DOC patients using the JFK CRS-R because a higher level of behavioral responses is needed for communication assessments than for many other assessments, such as an auditory startle assessment. Brain-computer interfaces (BCIs), which provide control and communication by detecting changes in brain signals, can be used to evaluate patients with DOC without the need of behavioral expressions. In this paper, we proposed an audiovisual BCI system to supplement the JFK CRS-R in assessing the communication ability of patients with DOC. In the graphic user interface of the BCI system, two word buttons (“Yes” and “No” in Chinese) were randomly displayed in the left and right sides and flashed in an alternating manner. When a word button flashed, its corresponding spoken word was broadcast from an ipsilateral headphone. The use of semantically congruent audiovisual stimuli improves the detection performance of the BCI system. Similar to the JFK CRS-R, several situation-orientation questions were presented one by one to patients with DOC. For each question, the patient was required to provide his/her answer by selectively focusing on an audiovisual stimulus (audiovisual “Yes” or “No”). As a case study, we applied our BCI system in a patient with DOC who was clinically diagnosed as being in a minimally conscious state (MCS). According to the JFK CRS-R assessment, this patient was unable to communicate consistently. However, he achieved a high accuracy of 86.5% in our BCI experiment. This result indicates his reliable communication ability and dem

With the development of information technology and the application of information technology jumped into popularity, the electronic document was used as a form of information transmission and data storage, more and more electronic documents are facing the risk of being illegally acquired and viewed. In order to solve this problem, this paper proposes a novel file content protection method, which based on the file content partitioning restructuring. This method strengthens the file content protection and improves the documents security. But it also greatly increases the speed of encryption and decryption process.

Considering the fraudulent behavior of Quality of Service (QoS) for web services, a method to monitor the QoS deviation was proposed in this paper. Firstly, we used random variable to describe the uncertainty of QoS. Secondly, the divergence of QoS in different time periods was tested with Kolmogorov Smirnov (K-S) approach. Finally, we utilized stochastic dominance to judge the better one of them. Theoretical analysis and experimental data showed that the proposed method was reasonable and effective. © 2015 IEEE.

The increasing complexity of the business processes requires automated methods for trouble-shooting and debugging of the process model in operation. This paper proposes mechanism of fault detection based on the concept of backwards reachability for the coloured workflow nets. The formal verification methods defined for coloured Petri nets such as state space method or place invariants declaration suffer from fast-growing computational complexity. The article offers the set of firing rules for backwards token-play on coloured workflow net. This method helps to detect resource-related failures of the two most common types: "the missing arc" fault (the resource was not initialized) and "wrong expression fault" (there is no proper resource).

Simulation support in construction uncertainty management: A production modelling approach

The execution of construction projects such as a highway construction or the elevation of a new bridge is a complex, highly equipment-intensive process and are subject to many different uncertainties. This is very similar to the manufacturing execution level in production systems where predefined productions plans and schedules cannot be completely implemented due to unexpected internal and external changes and disturbances. Following this analogy, the paper proposes the application of a discrete-event simulation based method which was already applied in the decision-support for manufacturing control to develop the decision-support in the execution of a construction project where the effects of the deviation from the short-term schedule can be easily and quickly analyzed.

In line with the theory of schema sampling, a hypothesis could be made that sufficient supply of loworder building blocks (BBs) was one of the necessary conditions for a genetic algorithm(GA) to work. A consequential question of this hypothesis regards, when a certain fitness function is optimized with a commonly used GA, whether it is rare or common that there are plenty of low-order BBs. It is remarked that, when a base-m encoded GA is applied to a fitness function that is linearly combined of sinusoidal basis functions with integral frequencies, it is unlikely to obtain order-1 BBs with fixed positions at multiple loci, i.e., it is rare that there are plenty of order-1 BBs. However, if a considerable part of the sinusoidal basis functions are with frequencies exponential to a positive integer m, a base-m encoding can provide relatively more order-1 BBs compared with the encodings with cardinalities other than m.

In this paper, we propose an automated surface inspection approach based on generalized low-rank approximations of matrices(GLRAM). The GLRAM uses a series of low-rank matrices to approximate the structural texture backgrounds of the original defective images. Then the difference images obtained by the original defective images and the low-rank approximations will retain the defect areas. Finally, we can easily segment the defect area from the original image using a simple threshold segmentation method. Experimental results show that our proposed method can extract defect areas well from the structurally textured image.

In this article, a Lyapunov-based control concept is presented combining variable structure and adaptive control. The considered system class comprises single-input systems which are affected by structured and unstructured uncertainties. The design is based on a Lyapunov function for the super-twisting algorithm. This Lyapunov function is exploited to derive the adaptive part of the proposed controller using the certainty equivalence principle. It is demonstrated that this combination of sliding-mode and adaptive control methodology allows to relax the boundedness condition known from the super-twisting algorithm while reducing the sliding-mode gain significantly. The effectiveness of the presented concept is demonstrated in detail, using results from numerical simulations and experimental data of a laboratory testbed. © 2015

Light urban electric vehicles are an important target, both for the researchers and manufacturers. Concerning the motor's choice, more ways are investigated, but the most important is that as compact as possible solutions have to be used. In the top of the preferences, the permanent magnet synchronous motors (PMSM) and brushless DC motors (BLDC) are situated. These are preferred thanks to their high power density, high efficiency and low maintenance cost. Even the main manufacturing technology and associated power electronics are quite similar, they essentially differ in the controlling technology, simpler and more advantageous being the BLDC. As integration technology, the in-wheel motor technology seems to be the one which improves the safety, efficiency, weight, controllability and finally the costs. Even the control principle is very well defined, the practical implementation can be different. The paper deals with four different control strategies for the BLDC motors. They are compared as technical implications and performances. © ECMS Valeri M. Mladenov, Petia Georgieva, Grisha Spasov, Galidiya Petrova (Editors).
