QoE Management of Multimedia Streaming Services in Future Networks: A Tutorial and Survey

The highly demanding Over-The-Top (OTT) multimedia applications pose increased challenges to Internet Service Providers (ISPs) for assuring a reasonable Quality of Experience (QoE) to their customers due to lack of flexibility, agility and scalability in traditional networks. The future networks are shifting towards the cloudification of the network resources via Software Defined Networks (SDN) and Network Function Virtualization (NFV). This will equip ISPs with cutting-edge technologies to provide service customization during service delivery and offer QoE which meets customers’ needs via intelligent QoE control and management approaches. Towards this end, we provide in this paper a tutorial and a comprehensive survey of QoE management solutions in current and future networks. We start with a high-level description of QoE management for multimedia services, which integrates QoE modelling, monitoring, and optimization. This followed by a discussion of HTTP Adaptive Streaming (HAS) solutions as the dominant technique for streaming videos over the best-effort Internet. We then summarize the key elements in SDN/NFV along with an overview of ongoing research projects, standardization activities and use cases related to SDN, NFV, and other emerging applications. We provide a survey of the state-of-the-art of QoE management techniques categorized into three different groups: a) QoE-aware/driven strategies using SDN and/or NFV; b) QoE-aware/driven approaches for adaptive streaming over emerging architectures such as multi-access edge computing, cloud/fog computing, and information-centric networking; and c) extended QoE management approaches in new domains such as immersive augmented and virtual reality, mulsemedia and video gaming applications. Based on the review, we present a list of identified future QoE management challenges regarding emerging multimedia applications, network management and orchestration, network slicing and collaborative service management in softwarized networks. Finally, we provide a discussion on future research directions with a focus on emerging research areas in QoE management, such as QoE-oriented business models, QoE-based big data strategies, and scalability issues in QoE optimization.
Learning from Trajectories via Subgoal Discovery /Author=Paul, Sujoy; van Baar, Jeroen; Roy-Chowdhury, Amit K. /CreationDate=October 31, 2019 /Subject=Applied Physics, Computer Vision, Machine Learning

Learning to solve complex goal-oriented tasks with sparse terminal-only rewards often requires an enormous number of samples. In such cases, using a set of expert trajectories could help to learn faster. However, Imitation Learning (IL) via supervised pre-training with these trajectories may not perform as well and generally requires additional finetuning with expertin-the-loop. In this paper, we propose an approach which uses the expert trajectories and learns to decompose the complex main task into smaller sub-goals. We learn a function which partitions the state-space into sub-goals, which can then be used to design an extrinsic reward function. We follow a strategy where the agent first learns from the trajectories using IL and then switches to Reinforcement Learning (RL) using the identified sub-goals, to alleviate the errors in the IL step. To deal with states which are underrepresented by the trajectory set, we also learn a function to modulate the sub-goal predictions. We show that our method is able to solve complex goal-oriented tasks, which other RL, IL or their combinations in literature are not able to solve.

Abstract
Foreign sourcing: vertical integration and firm heterogeneity

Based on the literature that considers that transaction costs, asset specificity and incomplete contracts play an important role in the “make or buy decision” this paper examines the characteristics of firms and the mode of organization– foreign vertical integration and/or foreign outsourcing – in intermediate inputs. The dataset we employ is based on firm level data of Spanish manufacturing firms that comes from Survey on Business Strategies (ESEE) and provides information and allows us to identify whether imports are intra-firm (related party) or at arm’s-length (non-related party). We focus on trying to discriminate some firms’ characteristics that influence on the probability that a firm integrates its activities in a foreign country through the estimation of a probit model. The results show that headquarter intensity, notably skill intensity and capital intensity; product differentiation and international experience have a positive influence in determining foreign integration even after controlling by other firm’s characteristics.

EVALUATING THE EFFECTS OF SCHOOL-BASED MINDFULNESS TRAINING ON EARLY ADOLESCENTS’ EMOTIONAL COMPETENCE AND ADJUSTMENT

Present research paper reports the findings of a non-equivalent control group quasi-experimental study which evaluated the effects of school-based mindfulness training program on eighth grade students (n=54: experimental =28, control=26). The program was delivered in the school during the school hours. Participants from experimental and control group were assessed on self-report measures of emotional competence (EC-scale), adjustment inventory (AISS) before, after the training and at follow up (after three months). Results were analysed by mixed ANOVA across the variables. Results indicated significant improvement in the emotional competence and adjustment (Emotional, educational and overall) of experimental group as compared to control group at post and follow up assessment. No significant group difference was noted in the social adjustment. Limitations and further scope of the study is discussed.

Update on geological investigations of the Notigi Lake area, Manitoba (parts of NTS 63O14, 64B3)

The second of two field seasons undertaken at Notigi Lake, located within the northern flank of the Kisseynew Domain, involved key traverses at low water levels and the application of a new high-resolution aeromagnetic survey. The fieldwork has contributed significant details to the structure, extent and composition of previously described rock types including the layered amphibolite, subdivisions in the Burntwood and Sickle groups and mafic to felsic intrusive rocks. The layered amphibolite unit is grouped with siliciclastic metasedimentary rocks in a volcano-sedimentary assemblage, (herein referred to as the ‘Notigi assemblage’). The Notigi assemblage is correlated with units that occur elsewhere along the northern flank of the Kisseynew Domain. Whole-rock majorand trace-element geochemistry and Nd-isotope data for the layered amphibolite support this correlation. Local sillimanite±garnet–bearing gneiss has been identified adjacent to the Notigi assemblage and the Burntwood Group. On the eastern side of the Notigi structure, Sickle Group arkosic units occur in the following order: 1) sillimanite-bearing gneiss, 2) biotitebearing gneiss, 3) hornblende-biotite gneiss, and 4) biotite gneiss. It is unknown if the most easterly sillimanitebearing gneiss represents the base of the stratigraphic section or if this succession is the result of isoclinal F1 folding above a fault that cuts off much of the section. The structural analysis at Notigi Lake can be directly applied to the structural style of similar units to the southeast, in the Thompson Nickel Belt. The geochemistry of monzodiorite that intruded Sickle Group rocks, including a newly found occurrence, establishes it to be part of the regional Black Trout diorite with a Nd-model age of 2.58 Ga.
Characterization and Health Risk Assessment of Volatile Organic Compounds in Gas Service Station Workers

Gas service station workers who work near volatile organic compounds (VOCs) sources, such as gasoline vapor emissions, and motor vehicle exhausts, may be exposed to highly elevated VOCs levels. This study investigates air samples from gas service stations in Thailand to evaluate the health risks following inhalation exposure. Personal air samplings were obtained at nine gas service stations in Chonburi, Thailand from October to December 2007. The concentrations of benzene, toluene, ethylbenzene, xylenes, and hexane in the air from the workplaces were significantly higher than in a control group of office workers (p<0.05). However, all VOCs in these air samples were lower than TWA limit of Thailand and the OSHA standard. Samples of urine, collected after 8-h work periods which were analyzed for VOCs metabolites, including t,t muconic acid, hippuric acid, mandelic acid and m-hippuric acid, demonstrate that the average levels of metabolites in gas service station workers and in controls were close, except for t,t muconic acid of gas service station workers which displayed higher levels than the in the controls. The lifetime cancer and noncancer risks for the workers exposed to VOCs were also assessed. Results show that all nine gas service stations in this study had a elevated lifetime cancer risk ranging from 53 to 630 per million, thus exceeding the “normal” risk of 1 per million. For noncancer risks, the levels in all gas stations ranged between 0.03 and 0.4, which is well below the reference hazard level of 1.0. Benzene may the most important cause of both cancer and noncancer risk followed by 1,3 butadiene.
Applying Multi-Level Theory to an Information Security Incident Domain Ontology

There is a substantial increase in the occurrence of information security incidents. To protect against these incidents, joint approaches, which include sharing incident information, are gaining particular importance. However, organizations do not have a clear distinction between the types of incidents and their specializations, leading to the same occurrence of incident being clas-siﬁed in different ways compromising the decision making process. In this paper it will be elaborated a domain ontology fragment about information security incidents applying Multi Level Theory (MLT) and the Uniﬁed Foundational Ontology (UFO) to make these concepts more explicit and, consequently, to facilitate interoperability within the domain.
Plant Extracts in the Bone Repair Process: A Systematic Review

Bone lesions are an important public health problem, with high socioeconomic costs. Bone tissue repair is coordinated by an inflammatory dynamic process mediated by osteoprogenitor cells of the periosteum and endosteum, responsible for the formation of a new bone matrix. Studies using antioxidant products from plants for bone lesion treatment have been growing worldwide. We developed a systematic review to compile the results of works with animal models investigating the anti-inflammatory activity of plant extracts in the treatment of bone lesions and analyze the methodological quality of the studies on this subject. Studies were selected in the PubMed/MEDLINE, Scopus, and Web of Science databases according to the PRISMA statement. The research filters were constructed using three parameters: animal model, bone repair, and plant extracts. 31 full-text articles were recovered from 10 countries. Phytochemical prospecting was reported in 15 studies (48.39%). The most common secondary metabolites were flavonoids, cited in 32.26% studies (n = 10). Essential criteria to in vivo animal studies were frequently underreported, suggesting publication bias. The animals treated with plant extracts presented positive results in the osteoblastic proliferation, and consequently, this treatment accelerated osteogenic differentiation and bone callus formation, as well as bone fracture repair. Possibly, these results are associated with antioxidant, regenerative, and anti-inflammatory power of the extracts. The absence or incomplete characterization of the animal models, treatment protocols, and phytochemical and toxicity analyses impairs the internal validity of the evidence, making it difficult to determine the effectiveness and safety of plant-derived products in bone repair.
Evaluation of antagonistic of Trichoderma spp. against Fusarium oxysporum f. sp. lycopersiciand Fusarium oxysporum f. sp. ciceri in in vitro

The objective of this paper was evaluatedto antagonistic of 14 different strain of Trichoderma species against Fusarium oxysporum f. sp. lycopersiciand Fusarium oxysporum f. sp. ciceri in in vitro.However, Fusarium wilt is a disease and one of the major yield limited factorswhich are harmful to economic important crop (Tomato and Chickpea). The antagonist of Trichoderma had been determined base on dualand its interaction. Here, II-method of dual culture was measured by Percent Growth Inhibition (Korsten L.) and MIC (Sangoyomi T.). Consituently,Invitro result of all Trichoderma strain was excellent as biological control agents due to PGI value more than 80%. However,Trichoderma virens(96.27%) was reduced to mycelium of Fusarium oxysporum f. sp. lycopersici as compared to other strain. In another hand,Trichoderma harzianumand Trichoderma viride(93.75%) was reduced to Fusariumoxysporum f. sp. ciceri.Therefore, Scale of MIC values were effective for all strain of Trichoderma according to Sangoyomi T.Conclusively, finding of the study indicates thatdifferent strain of Trichoderma has varied degree of antagonistic for both pathogens.
On the pressure oscillations inside a deep cavity excited by a grazing airflow

An experimental and theoretical study of the pressure oscillations generated by the flow over a deep cavity is p Such a configuration, which is akin to a Helmholtz resonator, arises in many applications, for instance when a wi the sunroof of an automobile remains open. The linear resonator model is fully validated by experiments. The linear characteristics of the free shear layer in the neck of the cavity ar e ret ieved from neck wall pressure measurements. An effic sound reduction scheme is proposed, which is based on the use of piezo-electric actuators placed upstream of the n elements act as small discrete flaps which force the shear layer in the neck to oscillate at a frequency distinct from t resonance frequency. A quasi complete attenuation of the peak pressure may then be achieved. The classical line analysis of the free shear layer is successful in accounting for the experimental observations and it leads to the identi the physical mechanism responsible for the efficiency of the sound reduction scheme. Moreove r linear stability theory yields limitations to the efficiency of the technique in the form of an energy criterion involving the Strouhal number.  2003 Elsevier SAS. All rights reserved.
The Relationship between Primary School Students' Computer- Internet Usage and Reading Habits: Sample of Konya 1

In this study, the relationship between primary school students' computer and Internet usage rates and their reading habits were examined. Data were collected over the Internet by online survey. The population of the research consisted of all students attending 5 th , 6 th , 7 th and 8 th grades in primary schools in Konya. The research was carried out by a survey model. Frequency, percentage and ratio techniques used for descriptive analysis and binomial regression technique were used for the relational analysis. Ratios and percentages were reported by the tables and graphics. Findings were discussed and interpreted with the related literature. SUMMARY Purpose and significance: Today, the technological factors that impact on the reading habits of primary school students are an issue to be investigated. Therefore, the aim of this study is to investigate the relationship between primary school students' computer and Internet usage rates and their reading habits. Methods: In this study, singular and relational survey methods were used. Singular survey method was used to determine the reading habits of students. The other was used to indicate the relationship between some variables and reading habits. The population of the research consisted of all students attending 5 th , 6 th , 7 th and 8 th grades in primary schools in Konya. In this survey, sample selection was not done because the population was tried to be reached. The data were obtained by using online survey that was done in the schools of centers of villages, towns, counties and city at 2 nd and 3 rd weeks of May 2010. Frequency, percentage and ratio techniques used for descriptive analysis and binomial regression technique was used for the relational analysis. Ratios and percentages were transformed into tables and graphics and findings were discussed and interpreted. Results: According to the results, 49.04 percent of the students have computers and 33.93 percent of the students have internet connection at their homes. 25.8 percent of the students read books regularly. It was understood that approximately 50 percent of the students read 2 or 3 books in a week. The most important result of the survey is that when the usage time of the internet is more than 1 hour and increases, the reading habit is affected negatively and decreases. Conclusion and Discussion: Results of the study show that approximately half of the students have computers and internet connection at their home. This ratio is increasing day by day. 25.8 percent of the students in primary schools read books regularly. The unconscious and uncontrolled usage of computer and internet technologies causes wasting time of the big part of the students. Reading habit is affected because of this situation. In this survey, it can be seen obviously that usage time of computer and internet affects reading habits of the primary school students. It can be said that the computer and internet usage time which is more than one hour is an important factor that prevents reading books regularly.
Response patterns in the developing social brain are organized by social and emotion features and disrupted in children diagnosed with autism spectrum disorder

Adults and children recruit a specific network of brain regions when engaged in "Theory of Mind" (ToM) reasoning. Recently, fMRI studies of adults have used multivariate analyses to provide a deeper characterization of responses in these regions. These analyses characterize representational distinctions within the social domain, rather than comparing responses across preferred (social) and non-preferred stimuli. Here, we conducted opportunistic multivariate analyses in two previously collected datasets (Experiment 1: n = 20 5-11 year old children and n = 37 adults; Experiment 2: n = 76 neurotypical and n = 29 5-12 year old children diagnosed with Autism Spectrum Disorder (ASD)) in order to characterize the structure of representations in the developing social brain, and in order to discover if this structure is disrupted in ASD. Children listened to stories that described characters' mental states (Mental), non-mentalistic social information (Social), and causal events in the environment (Physical), while undergoing fMRI. We measured the extent to which neural responses in ToM brain regions were organized according to two ToM-relevant models: 1) a condition model, which reflected the experimenter-generated condition labels, and 2) a data-driven emotion model, which organized stimuli according to their emotion content. We additionally constructed two control models based on linguistic and narrative features of the stories. In both experiments, the two ToM-relevant models outperformed the control models. The fit of the condition model increased with age in neurotypical children. Moreover, the fit of the condition model to neural response patterns was reduced in the RTPJ in children diagnosed with ASD. These results provide a first glimpse into the conceptual structure of information in ToM brain regions in childhood, and suggest that there are real, stable features that predict responses in these regions in children. Multivariate analyses are a promising approach for sensitively measuring conceptual and neural developmental change and individual differences in ToM.
