Guidance Method without Terrain Information for an Exploration Rover

This paper describes the guidance method considering irregular land of the planetary exploration rover in an unknown environment. Some exploration methods in the environment with many obstacles and uneven ground surfaces have been proposed. In this study, we propose a guidance method to detect and avoid the area that is difficult to be detected by an external sensor such as a camera or a radar. An observer based on Disturbance Accommodating Control (DAC) method is used to detect the areas. The potential function method is applied to the avoidance of the area. Furthermore, EKF-SLAM is treated to estimate self-location and construct a map in a more realistic environment. The effectiveness of the proposed method guidance method is verified numerically and experimentally.

Implementation of project-based learning at a technical university: teacher enthusiasm or resistance

The article describes implementation of project-based learning within the scope of different academic disciplines at a technical university. The research aims at analyzing various problem points that teachers face while organizing project work of students. The reasons complicating proliferation of project-based learning are observed. Methodology includes analysis of pedagogical studies, examination of project-based activities at universities, interviewing, and questionnaire survey. The findings lead to the conclusion that project-based learning is interesting for the majority of educators and is considered to be an effective type of activity. However, it is not widely used at a technical university. This happens because of a number o f difficulties that occur in the process of project planning and implementation. These are the issues of keeping up motivation, the lack of time for doing projects and presenting results, unwillingness of students to take up self-studies, problems with control and assessment, unevenly distributed learning. The author proves the necessity of teacher professional development in this sphere. The most important units of the programme have been specified. It is recommended that the course trains educators to plan projects with due regard to curriculum, to share knowledge and develop skills significant in a specific area of studies, to nurture contemporary co mpetencies, such as confidence, perseverance, innovative thinking, creativity, flexibility, openness, sociability, teamwork. Moreover, the article describes the importance of discussing the methods of implementing short-term and international projects. According to the research, these types of project work are organized less frequently than the other ones.
Random Restrictions of High-Dimensional Distributions and Uniformity Testing with Subcube Conditioning

We give a nearly-optimal algorithm for testing uniformity of distributions supported on $\{-1,1\}^n$, which makes $\tilde O (\sqrt{n}/\varepsilon^2)$ queries to a subcube conditional sampling oracle (Bhattacharyya and Chakraborty (2018)). The key technical component is a natural notion of random restriction for distributions on $\{-1,1\}^n$, and a quantitative analysis of how such a restriction affects the mean vector of the distribution. Along the way, we consider the problem of mean testing with independent samples and provide a nearly-optimal algorithm.
Prima e dopo la cura: nuove dimensioni nella tutela della salute

The essay investigates the extent and the limits of “medicine beyond the cure”, from the point of view of constitutional law. Individual and collective prevention interventions, vaccination campaigns, health promotion through correct life-styles, palliative care, are just some examples of the expansive motion of medicine and its boundaries. On this ground, we find the problem of the balance between the individualistic dimension and the solidarity dimension in the protection of the right to health. In the concluding part, some critical points are highlighted regarding the spread of non-conventional medicines, which seem to project cure “beyond the medicine”.

Decrease Product Rating Uncertainty Through Focused Reviews Solicitation

Customer reviews are an essential resource to reduce an online product’s uncertainty, which has been shown to be a critical factor for its purchase decision. Existing e-commerce platforms typically ask users to write free-form text reviews, which are sometimes augmented by a small set of predefined questions, e.g. “rate the product description’s accuracy from 1 to 5.” In this paper, we argue that this “passive” style of review solicitation is suboptimal in achieving low-uncertainty “review profiles” for products. Its key drawback is that some product aspects receive a very large number of reviews while other aspects do not have enough reviews to draw confident conclusions. Therefore, we hypothesize that we can achieve lower-uncertainty review profiles by carefully selecting which aspects users are asked to rate. To test this hypothesis, we propose various techniques to dynamically select which aspects to ask users to rate given the current review profile of a product. We use Bayesian inference principles to define reasonable review profile uncertainty measures; specifically, via an aspect’s rating variance. We compare our proposed aspect selection techniques to several baselines on several review profile uncertainty measures. Experimental results on two real-world datasets show that our methods lead to better review profile uncertainty compared to aspect selection baselines and traditional passive review solicitations. Moreover, we present and evaluate a hybrid solicitation method that combines the advantages of both active and passive review solicitations.
Image Denoising Based on adaptive Morphological Edge Detection and Wavelet Fusion

The effect of traditional wavelet denoising algorithms is not very good and the detail precision of the image isn't high enough. What is worse, it will damage the edge and corner information of the image, and lose texture details. To solve problems above, a new method based on adaptive morphological edge detection and wavelet fusion is proposed. Firstly, the noisy image is decomposed with two wavelet bases. Then we divide the wavelet coefficients into two parts by using the adaptive morphological edge detection method. Secondly, we deal the wavelet coefficients of the edge by using the improved threshold and the hard threshold function. Thirdly, we deal the others by using the improved wavelet threshold and the improved threshold function. At last, we obtain the denoising image by using the wavelet fusion algorithm. Results of the experiment show that the new method can not only highlight the characteristics of the image texture, but also can remove the noise without hurting the important characteristics and the texture edges at the same time. So the new method has great application value.

Decoherence effects on quantum Fisher information of multi-qubit W states

Quantum fisher information of a parameter characterizing the sensitivity of a state with respect to parameter changes. In this paper, we study the quantum fisher information of the W state for four, five, six and seven particles in decoherence channels, such as amplitude damping, phase damping and depolarizing channel. Using Krauss operators for decoherence channels components, we investigate the quantum fisher information quite analytically. We observe that for the W state, the amount of the quantum fisher information and consequently, the amount of entanglement are reduced by applying the quantum noises, which affect each particle in the same way. In some cases, a relative increase appears in the quantum fisher information for certain values of the decay strength p. We also show that the phase damping channel vanishes the value of the quantum fisher information for the W state.
STUDY ON COMPOSITE COAGULANTS-FLOCCULANTS MECHANISM ACTION

This research deals with the investigation of adsorption characteristics of different types of composite coagulants-flocculants, combined by polyaluminum chloride (aluminum oxychloride) with organic polymer. The effect of this composite coagulants-flocculants on solution's turbidity removal and characteristics of cohesion and coagulation process have been studied too. On the basis of experimental data obtained the character and mechanism of cohesion and coagulation for different types of composite coagulants-flocculants were discussed. It was stated out that the adsorption isotherm of cationic composite coagulants-flocculants conforms to Langmuir adsorption law, and it characterized by monolayer adsorption parameters, which increases their ability to neutralize electric charge. The anionic composite coagulants-flocculants enhance the adsorption value and bridging ability with the help of organic polymers, showing multilayer adsorption characteristics. It was observed specifically, that under the same conditions the flocculation rate and sedimentation rate of composite coagulants-flocculants are higher than polyaluminum chloride has. This fact was explained by the advantages of organic polymer due to its long chain which is able to form larger floc within short time. The large floc has strong attractive potential energy for tiny particles, which make the opportunity of effective collision between particles what leads to sharply increased coagulation. The influence of storage time period on composite coagulants-flocculants coagulation effectiveness has been examined. The experimental results witness that the coagulation characteristics of reagents will be reduced to some extent after long-term storage, but composite coagulants-flocculants have advantages in this aspect over polyaluminum chloride. It should be concluded that, in general, the quality of composite coagulants-flocculants in relation to their stability remained at a high level.&#x0D; &#x0D; &#x0D;
