This paper is devoted to the investigation of position estimation for a brushless DC machine using only their stator currents. The first application is for a hybrid electric vehicle, where the generator will be used as a motor to start the internal combustion engine (ICE).

This paper describes how to estimate the rotor position of a brushless DC (BLDC). Two different strategies, both based on stator currents, will be used: one for low speeds to start the ICE, and one for normal speeds for future applications in a pure electric vehicle (EV). The first one uses an estimation method based on core saturation and the second one is based on the determination of the current slopes on two of the three phases. The algorithms proposed neither needs to measure any machine parameters, nor the back emf. The methods use the information contained in the current magnitudes and slopes, and the machine mechanical speed. The system was implemented using a Digital Signal Processor (TMS320F241), which controls the phase currents and makes all the calculations required for position estimation. Additionally, the PWM signals are transmitted through a fiber optic link to minimize noise production and error on commutations.

The papers shows how an internal combustion engine can start using this approach in a brushless motor and keep it synchronized.

This work is being applied to a hybrid electric vehicle.

The paper proposes a new way to start the internal combustion engine for hybrid vehicle applications through the estimation of the magnet's position. It also shows a way to estimate the position at other speeds for battery charging of the vehicle.

More and more diversity is present in our classrooms. As teachers, we must be able to respond to the different levels of learning presented by our students. Therefore, it is necessary to use the new emerging technologies as elements of response. Thus, the purpose of this paper is to develop a systematic and thematic review of the application of augmented reality (AR) in the learning of autistic students in the educational setting during the period 1996–2020 using the Web of Science and Scopus databases.

For this purpose, one of the bibliometric techniques called systematic and thematic review has been used. This technique is supported by the preferred reporting items for systematic reviews methodology, and it uses a quantitative and qualitative approach. The thematic analysis will be carried out on 28 documents based on a series of indicators, including sample size, hardware devices, way of storing the information and findings obtained in the research.

The results of the work indicate that the average size of the sample is three participants, and that the most worked area has been social skills using tablets. In addition, bookmarks are often used as an element of information storage in AR.

The main contribution of this work focuses on the establishment of a series of thematic variables that will serve for the later development of an action protocol for the creation of AR activities for autistic students.

Increased evidence for the health benefits of probiotics for health restoration coupled with the consumer's inclination towards a safe, natural and cost-effective substitute for drugs have led application of probiotics as a pharmaceutical agent and are rapidly moving in clinical usage. In this context, this article attempts to highlight the potential of probiotics as a pharmaceutical agent.

Endeavor has been made to explore the significance of probiotics for the modulation of gut ecology and their action. Potentiality of probiotics for their exploitation as a pharmaceutical agent has also been justified. Limitations of probiotic therapy and the various considerations for probiotic therapy have also been delineated.

Probiotic organisms influence the physiological and pathological process of the host by modifying the intestinal microbiota, thereby affecting human health. Beneficial effects of probiotics as a pharmaceutical agent seem to be strain and dose dependent and more efficacious with their early introduction. Combination of various probiotics proved to be more efficacious than single strain for exhibiting prophylactic activities.

Reviewed literature indicated that it is difficult to generalize for the beneficial effect of all probiotics for all types of diseases as efficacy of probiotics is strain-dependent and dose-dependent and its clinical application needs long-term investigations.

Clinical trials have displayed that probiotics may alleviate certain disorders or diseases in humans especially those related to gastro-intestinal tract.

Ingestion of fermented dairy products containing probiotic cultures may provide health benefits in certain clinical conditions such as antibiotic-associated diarrhoea, rotavirus-associated diarrhoea, inflammatory bowel disease, inflammatory bowel syndrome, allergenic diseases, cancer, Helicobacter pylori infection and lactose-intolerance. Application of probiotics as a pharmaceutical agent is recommended.

This paper aims to increase the understanding of luxury brands’ branded content strategies concerning follower's engagement generated or not by happiness and well-being feelings spread in their branded content.

This study sample was composed of three of the most relevant luxury brands nowadays: Manolo Blahnik, Loewe, y Balenciaga. To address this research, an exploratory-correlational quantitative methodology was chosen; hypotheses were contrasted using ANOVA analysis with the SPSS software. Although the study can be considered quantitative, the first step of qualitative analysis was applied for content analysis with NVivo QSR software, categorizing all posts (N = 192) into three categories.

The dissemination of branded content and corporate social responsibility, despite being different in each case, show in general an interaction and affective commitment with their stakeholders. In the specific case of Manolo Blahnik and Loewe, they have prioritized their content, in the context of the pandemic, in posts related to social welfare, happiness, mental and physical health care. There are significant differences in the interaction with their audience, which respond very favorably to both “Happiness” and “Health and safety” content.

This study reveals how corporate social responsibility can be achieved using efficient communications in social networks. In this way, the perception of the image of the sector and the reputation can be improved – both sectoral and organizational – which unquestionably translates into economic gains for the brands.

This paper continues the analysis of the data collected in a survey of quality function deployment (QFD) carried out in Brazil, and deepens the study by carrying out interviews at some of the companies which participated in the survey to identify best practices on QFD application.

To analyze the data collected in a survey of QFD and interviews, eight exemplary criteria based on the QFD literature were considered. The paper then presents and discusses best practices in QFD application.

The results of analyzing the interviews showed that there were exemplary aspects in the use of the method and the key points in the QFD implementation that should be considered were related to: support from upper management, carrying out training, creating the team, frequency and length of meetings, and creating a conceptual model, among other aspects.

It is important to stress that the importance of some of these exemplary aspects varies with the type of company and the product developed with QFD, and could be less important for other products and industries.

The results showed that there were key points in the QFD implementation that should be considered depending on type of company and the product.

The key points in the QFD implementation identified in this paper may be useful to QFD users and academics.

The objective of this paper is twofold: first to determine to what extent Spanish public hospitals are using their web sites to provide useful information to users and to improve hospital‐patient relationships, and second to determine which factors have an influence on web site adoption and level of development over time.

The web sites of public hospitals were searched for and analysed in 2005 and 2008. Their contents and features were scored using an 86‐item checklist. Several hypotheses were proposed regarding the influence of internal and external factors on web site adoption and level of development. Logit and linear regressions were conducted to test the proposed hypotheses.

Half of the Spanish public hospitals do not have a web site. The hospital web sites were acceptable in the information dimension but should improve their interactive features, as well as their navigation and usability. No significant improvements were observed during the period analysed. The size of the hospitals was a determining factor for web site adoption and level of development in both years. However, from 2005 to 2008, external factors – in particular internet penetration – became a significant factor to explain the adoption and level of development of web sites.

Citizens are increasingly relying on the internet to search for health‐related information. Hospital managers should exploit the advantages of implementing and properly developing a web site in order to improve the patient‐care provider relationships and offer citizens reliable information about healthcare.

To date, no empirical study has analysed the factors that influence the implementation of hospital web sites or the evolution of their contents and quality over time.
