In the current era, a rapid increase in data volume produces redundant information on the internet. This predicts the appropriate items for users a great challenge in information systems. As a result, recommender systems have emerged in this decade to resolve such problems. Various e-commerce platforms such as Amazon and Netflix prefer using some decent systems to recommend their items to users. In literature, multiple methods such as matrix factorization and collaborative filtering exist and have been implemented for a long time, however recent studies show that some other approaches, especially using artificial neural networks, have promising improvements in this area of research. In this research, we propose a new hybrid recommender system that results in better performance. In the proposed system, the users are divided into two main categories, namely average users, and non-average users. Then, various machine learning and deep learning methods are applied within these categories to achieve better results. Some methods such as decision trees, support vector regression, and random forest are applied to the average users. On the other side, matrix factorization, collaborative filtering, and some deep learning methods are implemented for non-average users. This approach achieves better compared to the traditional methods.

To improve the energy efficiency of the wireless sensor network (WSN), and extend the network life. This paper proposes an improved unequal clustering multipath routing algorithm (UCMRA). The algorithm improves the formula of cluster head selection probability and competition radius, and considers the energy factor, node density, optimal number of cluster heads, etc. Experimental results show that, compared with the traditional algorithm, UCMRA has more stable cluster head distribution, less energy consumption and longer network lifetime.

The present work aims to investigate the conditions for improving the containment of spent ion exchange resin (IER) as a radioactive waste, using powdered Callovo-Oxfordian clay (COx) as an addition to the cementitious matrix at different rates. The aim of this work was to investigate the influence of COx on the characteristics of cemented packages of spent (REI). In this context, a cemented pack was made using Portland class 45 cement, sand, resin and water. And others are prepared by replacing the sand with COx, in the following proportions: (2%, 4%, 6%, 8% and 10%). The packages obtained with and without COx were measured for their compressive strength and porosity.

After Békésy the stapes base moves around two axes: for weaker sounds - rotates around its transverse axis; in case of a strong sound - it moves around its longitudinal axis. Békésy’s place theory cannot alone explain the frequency-distinguishing ability of the ear. However, the existence of active amplification further sharpens the frequency-analysing ability of the cochlea. In addition, the different frequency sensitivity of afferent nerve fibres of inner hair cells synergizes with the mechanisms above. Peaked resonance curves are consequences of different threshold sensitivities of nerves connecting to individual hair cells. The frequency, which belongs to the lowest stimulus threshold, is called the characteristic frequency of a nerve. This place assignment of nerve frequencies are formed by the following mechanism in the cochlea. The place of amplitude maxima of progressive waves excited in the basilar membrane shows slight frequency dependence. The mechanism of active amplification forming in outer hair cells amplifies and sharpens the resonances of the basilar membrane. In 1961, nobleman Georg von Békésy received the Nobel Prize in Medicine: “for his discoveries of the physical mechanisms of stimulation within the cochlea”.

In Morocco, physical education (PE) in primary school is justified by its contribution to the integral formation of children. It has a positive impact on the development of the personality of those who invest in it. This is the reason why PE is included as a separate subject in the curricula of the different levels of the primary cycle. However, several factors minimise the effect of practising PE in schools and make it difficult for PE to make a real contribution to the development of children's personalities.This article therefore sets out to show that in the absence of rational programming, qualified physical educators and suitable and sufficient material conditions, PE cannot claim to make a real contribution to the development of children's personality.

The concept of fuzzy dot subalgebra of BCK/BCI-algebras was introduced by Jun and Hong paper [8]. In 2003 Jun [7] was introduced the concept of satisfactory BCK-filters. The concept of fuzzy satisfactory BCK-filters was introduced by Najati [13]. In this paper, we define the notion of fuzzy dot satisfactory BCK-filters and investigate some of its properties.

This study deals with sport at the Abdelmalek Essaâdi University-Tetouan Morocco (UAE). It adopts a problematic related to the development of the sport/Physical Education (PE) system in this Moroccan public university. After identifying the factors responsible for the dysfunction of this system [1], the study makes a proposal to revitalise Sports Activities and PE in the KAU and its affiliated institutions. In order to answer the question of effective measures to be taken to improve the quality and quantity of the PES/sport system in the KAU, our method of approach consists of intervening by positivising, in the particular context of the UAE, the negative indicators. Upstream, we propose an operational approach with the aim of bringing together the favourable conditions for the success of this initiative.

The hearing analyzer consists of two main systems: the peripheral hearing system, formed of the outer ear, the middle ear and the inner ear and the central hearing system, which contains the nervous pathways which ensure the transmission of the nervous influx and the hearing area where the information is analyzed and the hearing sensation is generated. The peripheral hearing system achieves the functions of transmission of the sound vibration, the analysis of the acoustic signal and the transformation of the acoustic signal in nervous inflow and the generation of the nervous response. The human hearing is characteristics: 1. The eardrum vibrates from the sound waves; 2. Auditory ossicles amplify the stimulus; 3. In an oval window, the vibration is transmitted to the fluid space of the inner ear; 4. It vibrates the basilar membrane; 5. What is pressed against the membrane tectoria; 6. The stereocilliums of the hair cell bend, ion channels open; 7. Hair cell depolarizes; 8. Stimulus is dissipated in cerebrospinal fluid VIII (vestibulo¬cochlearis); 9. Temporal lobe primary auditory cortex (Brodman 41, 42); 10. Association pathways: speech comprehension (Wernicke area).

This research deals with the issue of Physical Education (PE) and Sport at Abdelmalek Essaâdi University, Tetouan, Morrocco. It adopts a problem related to the diagnosis and development of the Physical Education/sport system in this Moroccan institution of public higher education. After verifying whether certain factors are responsible for the dysfunction of this system at the UAE, this study subsequently makes proposals that could contribute to improving its performance. The results of this study show that the PE/sport system in the UAE suffers from a more or less significant lack, in number and quality, of human, financial, material and infrastructural resources. On the other hand, a deficient and non-functional organization, the absence of management strategies, the omission of regular evaluation of the system, the low motivation and the lack of commitment of the administrative and associative actors mark the managerial approach of the sports sector in the majority of schools and faculties of the UAE. Consequently, we conclude that all of these elements are responsible for the dysfunctional situation that PE and sport are currently experiencing in the UAE. Also, the conclusions of this study reveal the way in which the leaders in this university represent the importance of sport activities among the educational, academic and para-academic offer. All of them are in favor of developing sports in their institutions, but without being really determined and equipped to make it happen.
