Big Data Analytics in the Entertainment Industry: Audience Behavior Analysis, Content Recommendation, and Revenue Maximization

This research contributes to the understanding of the significant role of big data analytics in transforming the entertainment industry. In this study, we investigate the impact of big data analytics on the entertainment industry, focusing on three key aspects: audience behavior analysis, content recommendation, and revenue maximization. To understand audience behavior, entertainment companies leverage big data analytics to collect and analyze vast amounts of data from various sources, including social media platforms, streaming services, ticket sales, and website traffic. By analyzing viewer preferences, engagement metrics, and geographic information, companies gain valuable insights into audience behavior. These insights help in creating content that resonates with the target audience, optimizing future content creation, and tailoring marketing strategies based on geographical preferences. Furthermore, big data analytics plays a vital role in powering content recommendation systems. Through collaborative filtering and content-based filtering techniques, entertainment platforms personalize content recommendations based on user behavior, preferences, and historical data. This enhances user satisfaction and increases the likelihood of discovering relevant and appealing content. Hybrid approaches that combine collaborative and content-based filtering techniques are also explored to achieve more accurate and diverse recommendations. Moreover, big data analytics enables entertainment companies to optimize revenue generation strategies. By analyzing historical data, market trends, and consumer behavior, companies can implement dynamic pricing strategies, adjusting ticket prices, subscription fees, or content pricing based on demand and viewer preferences. Additionally, targeted advertising based on user data enhances advertising revenue by delivering personalized advertisements. Furthermore, analyzing market data and consumer behavior patterns helps optimize licensing agreements and content distribution strategies, maximizing revenue opportunities

Motivating Reluctant EFL Students to Talk in Class: Strategies and Tactics

This research paper deals with a variety of strategies and tactics employed by teachers in the classroom to motivate reluctant students to converse and participate. Various scholarly articles are critically reviewed, taking into account fundamental motivational strategies such as enhancing communication, minimizing negative factors (including anxiety, apprehension and stress), teaching through games, as well as other co-curricular activities. In addition to these strategies, the role of teachers, parents and students is also considered. Finally, the paper presents some essential recommendations for the improvement of the current practices of classroom motivation

ChatGPT and the EFL Classroom: Supplement or Substitute in Saudi Arabia’s Eastern Region

This paper compares EFL learners satisfaction with teacher-mediated versus ChatGPT-assisted writing opportunities. Results show that, except for ease of use, learners reported greater satisfaction with the teachers role in all other factors, with the construct of interactive opportunities in the teacher mediated period rated the highest contributor to learning satisfaction, while the component of learning content being reported to be ‘almost satisfied in teacher mediated mode. The study was based on 64 EFL learners’ perceptions of learning satisfaction in teacher- mediated versus bot-created writing opportunities using factor analysis of data generated from responses to five open- ended questions at a language learning institution in the Eastern Region in Saudi Arabia. The data collection period was four weeks, and learners’ responses were sought in an eight-item written interview which loaded onto four learning satisfaction components: Learning content, learning progress, ease of use, interactive opportunities. We suggest that ChatGPT can supplement the learning process but cannot replace the teachers role without proper training for cautious use as ChatGPT does not help in students progress due to the lack of learning satisfaction attained in the use of this tool

Experimental and Computational Crushing Behaviour of Laminated Composite Shells

This thesis presents the effect of structural geometry, reinforcement type and hybridisation on the crushing behaviour, energy absorption, failure mechanism and failure mode of cylindrical, conical and compound composite shell. The static crushing behaviour of cylindrical, conical and compound composite shell under uniform axial load has been investigated, experimentally, analytically and numerically. Four types of composites were tested, namely, carbon fibre/epoxy, glass fibre/epoxy, oil palm frond fibre/epoxy and the carbon-glass hybrid. This work also examines the effect of the residual stresses built on the crushing behaviour; energy absorption, failure mechanism and mode of failure of the filament wound laminated circular conical composite shell. For the circular cylindrical and conical shells, the cones vertex angles tested were 0, 6, 12,and ISO. Results for the glass/epoxy circular cylindrical shell show that the stress distribution is constant along the shell generator. On the other hand results for the glass/epoxy circular conical shells with vertex angles of 6, 12 and 18 degrees show that the stress distribution is sensitive along the shell generator. As the vertex angle increases, the average crushing load increases, while the initial failure load decreases. The compound shells used in this investigation were the cone-cone and conecylinder- cone intersection composite shells. For the cone-cone intersection shells, the cone vertex angles were 10°, 15°, 20° and 25°. While for the cone-cylinder-cone, the cone vertex angles are 10° and 15° and the cylindrical part lengths were varied between 0 and 50mm. The results showed that the initial failure was dominated by interfacial and shear failure, while the delamination and eventually fibre fracture dominated the failure mechanism after the initial first failure. For the circular cylindrical and conical shells, the proposed analytical solution well predicts the initial failure load for the circular cylindrical and conical laminated composite shells. The failure criteria used to predict the initial failure show an excellent agreement. For the cone-cone intersection composite shell, the results showed that the structures with vertex angles 20° and 25° exhibited good energy absorption capability. For the cone-cylinder-cone, numerical results show that high-localised stress has been concentrated at the junctions between the cylinder and cones. Experimental results showed that structures of cylindrical part length varies between 10 and 20mm exhibited good energy absorption capability and stands a very high crushing load

Existence result for a strongly coupled problem with heat convection term and Tresca's law.

International audienceWe study a problem describing the motion of an incompressible, nonisothermal and non-Newtonian uid, taking into account the heat convection term. The novelty here is that uid viscosity depends on the temperature, the velocity of the uid, and also of the deformation tensor, but not explicitly. The boundary conditions take into account the slip phenomenon on a part of the boundary of the domain. By using the notion of pseudo-monotone operators and xed point Theorem we prove an existence result of its weak solution

Stability Analyses for Porous Convection Including Second Sound Effects

We investigate various models of thermal convection in a fluid saturated porous medium of both Darcy and Brinkman types. The linear instability and global (unconditional) nonlinear stability thresholds are analysed. Analytical solutions and numerical solutions are obtained by employing the $D^2$ Chebyshev tau and compound matrix techniques, and we investigate the effect that the inertia term and other physical parameters have on the stability of the system. The thesis is split into two parts. In PartI we consider a coupled model of thermal convection in a fluid saturated porous material and theories of viscous fluid motion which allows heat to travel as a wave. This is discussed in the first three chapters. In Chapter 2 the instability mechanism is investigated in complete detail and it is shown that stationary convection is likely to prevail under normal terrestrial conditions, but if the thermal relaxation time is sufficiently large there is a possible parameter range which allows for oscillatory convection. However, the presence of the Guyer-Krumhansl terms has the effect of damping the oscillatory convection and returning the instability mechanism to one of stationary convection. In Chapter 3 the constitutive equation for the heat flux is governed by a couple of the Guyer-Krumhansl equations and the Cattaneo-Fox law. In particular, we study the effects of the Guyer-Krumhansl terms on oscillatory convection. It is found that for a certain range of the Guyer-Krumhansl coefficient stationary convection occurs while changing the range results in oscillatory convection. Numerical results quantify this effect. The thermal instability in a Brinkman porous medium incorporating fluid inertia for both free--free and fixed--fixed boundaries is considered in Chapter 4. We have incorporated the Cattaneo--Christov theory in the onstitutive equation for the heat flux. For fixed surfaces, the results are generated by using the $D^2$ Chebyshev tau method. The results reveal that employing the Cattaneo--Christov theory has a pronounced effect in determining the convection instability threshold. Part II concerns the effect of an anisotropic permeability on thermal instability in the modelling problems of thermal convection of Darcy type with and without the inclusion of an inertia term, which represented the last three chapters. In Chapter 5 we allow a non-zero inertia term and also allow the permeability to be an anisotropic tensor. For particular numerical results we consider the case when the vertical component of the permeability tensor is variable. Linear instability results are calculated numerically and it is proved that the nonlinear energy stability bound is the same as the linear one. We perform the linear instability and nonlinear stability analysis, in the case where the inertial term vanishes, to investigate the effect of anisotropy with rotation on the stability thresholds in Chapter 6, showing that the nonlinear critical Rayleigh numbers coincide with those of the linear analysis. The results reveal that the inclusion of the inertial term for this model can play an important role on the onset of convection in Chapter 7

Physiological and molecular responses in the pulp associated with early inflammatory process

PhD ThesisTherapies to promote pulp repair and regeneration after injury should be underpinned by a deep understanding of normal tissue behaviour, cellular cross-talk and regulation. The objectives of this study were to investigate the expression of cyclooxygenases (COX1 and COX2), prostanoid receptors (EP1 and EP2) and nitric oxide synthase 1 (NOS1) within the normal dental pulp. The effect of experimental inflammatory conditions on these elements at mRNA level (both normal and experimentally inflamed) were investigated to explore the possibility of a nitric oxide (NO)/prostaglandin (PG) signalling pathway interaction in the rat mandibular incisor (normal and experimentally inflamed). Rodent mandibular incisors were utilised as a model throughout this thesis with structural and functional investigations on demineralised teeth, non-demineralised freshly extracted pulp tissues and tissue explants. The work described in this thesis used immunohistochemical, ELISA and quantitative reverse transcription polymerase chain reaction (q-RT-PCR) techniques. Cellular heterogeneity was observed both in the odontoblasts population and in the interstitial cells forming the bulk of the pulp. Cellular processes were also observed in addition to the observation of cellular processes extending from interstitial cells in the cell-rich zone to odontoblasts. The presence and localisation of immunoreactivity to the above mentioned targets (COX1, COX2, NOS1 and prostanoid receptors) are novel and confirmed with q-RT-PCR. Isolated pulp tissues exposed to LPS were found to release an increased amount of PGE2, which was found to be inhibited by other factors like the presence of NO and ATP. Functional cross-talk between PG and NO was investigated by the ELISA technique, with experimentally-induced inflammation increasing PG release, whereas NO and ATP caused inhibition of PGE2 release. The effects of carefully selected pro-inflammatory agents (LPS, NO and ATP) on PG pathway were examined at the mRNA level by q-RT-PCR. Exposure to LPS was found to cause upregulation of all target genes, whereas variable reactions were observed in response to incubation with NO, ATP and PGE2.Iraqi Ministry of Higher Education and Babylon Universit
