QoE-Centric Network-Assisted Delivery of Adaptive Video Streaming Services

Video streaming traffic has gone through an impressive growth over the last ten years. This growth can be rooted back to two different causes, namely widespread content accessibility and improved delivery techniques, such as HTTP Adaptive Streaming (HAS) and Web Real-Time Communication (WebRTC). HAS techniques are widely used in Video-on-Demand and live streaming scenarios, while WebRTC is mostly used in interactive streaming applications. Both HAS and WebRTC are unfortunately still affected by several inefficiencies. In HAS, the video client is equipped with a heuristic to dynamically adapt the video quality to the available network resources. This client-based adaptation cannot always guarantee the best experience to the end users, the so-called QoE. On the other hand, WebRTC is by design peer-to-peer, which makes this technique not scalable when the number of users in the system is high. To solve these problems, this PhD thesis proposes an advanced architecture where additional intelligent components are placed in the network to support the delivery of the video. Moreover, the designed network components aim at optimizing specific QoE parameters that directly impact the users’ viewing experience, rather than QoS parameters, which represent low-level network performance. This architecture has been applied, for example, to reduce playout interruptions in the video playback of HAS clients up to 45% or to increase the scalability of WebRTC systems without affecting the delivered video quality.
Verso un’individuazione del “disagio linguistico”

Towards an identification of “Linguistic Unease”. This paper argues that the assessment of sociolinguistic justice should pass through the promotion of linguistic ease, analysed through a number of sociolinguistic parameters already in use for the repertoires of multilingual communities. Their consideration makes it possible to focus on complexity of globalising and localising forces, beyond the West phalian model of nation-state. In particular, three axes of analysis should be taken into account: the formality of situations; the sense of belonging; special domains, like school and writing. KEYWORDS: Sociolinguistics, linguistic repertoire, linguistic justice, linguistic unease
Design of Intelligent Watering System Based on STM32

The purpose of this paper is to develop intelligent watering robot based on STM32 for indoor breeding flowers and plants, which can realize functions such as intelligent watering, foliar spray and automatic watering.  Considering that the water storage capacity of the airborne water tank is small, it is unable to cope with the needs of the water-loving plants or going out for a long time. By using the robot occupants, it is only necessary to regularly store the water in the water tank to ensure the living environment of the flowers and plants in the home, thereby reducing the burden on the occupants to care for the flowers and plants in the house, or to take good care of the flowers and plants at home when the occupants go out.

Using Tab Bars and Tool Bars

Like a Navigation Controller, a Tab Bar Controller also groups related view controllers together. The main difference is that a Navigation Controller can only display view controllers in sequential order. On the other hand, a Tab Bar Controller can jump to another view controller directly.
An Empirical Evaluation of the Effect of Adversarial Labels on Classifier Accuracy Estimation

This paper examines the effect of providing adversarial labels to several algorithms that use noisy labels from multiple experts to estimate classifier accuracy, referred to hereafter as We propose four adversary labeling strategies and use experiments on synthetic data to gauge their impact on the estimators. Our results show that even a single adversary can considerably impact the effectiveness of an estimator. In addition, we find that estimators that weight the input of all experts equally tend to be much more affected by the inclusion of adversaries than those that can separately model each expert and that the impact of adversaries is lessened when the experts have higher accuracy.
Answer Distillation for Visual Question Answering

Answering open-ended questions in Visual Question Answering (VQA) is a challenging task. As the answers are totally free-form, the answer space for open-ended questions is infinite in theory. This increases the difficulty for algorithms to predict the correct answers. In this paper, we propose a method named answer distillation to decrease the scale of answer space and limit the correct result into a small set of answer candidates. Specifically, we design a two-stage architecture to answer a question: First, we develop an answer distillation network to distill the answers, converting an open-ended question to a multiple-choice one with a short list of answer candidates. Then, we make full use of the knowledge from the answer candidates to guide the visual attention and refine the prediction results. Extensive experiments are conducted to validate the effectiveness of our answer distillation architecture. The results show that our method can effectively compress the answer space and improve the accuracy on open-ended task, providing a new state-of-the-art performance on COCO-VQA dataset.

Mining Patterns in Mobile Network Logs

Alarm logs are a valuable source of information and play a crucial role in network management. Network devices such as backbone routers or 3G/4G base stations generate verbose and detailed logs that network managers process to detect problems and identify their root causes. Manual analysis of such logs is extremely time-consuming because of the extensive amount of data. Therefore, finding suitable automatic methods to process logs is an important problem in the network analysis area.In this paper, we target the automatic extraction of situations, i.e., sequences of events occurring close in time and space which identify common and recurring patterns. We adopt an unsupervised machine learning approach to automatically mine logs and provide information and correlations in network failures. We face a real use case processing more than 2 million alarms generated by 2 months of TIM Network Operations Center in Northern Italy. Most of the features are categorical and call for specific methodologies to process them. We choose rule mining of frequent items. We focus on event logs and apply rule mining methods to extract temporal-spatial correlations and co-occurrences, i.e., situations. To ease the analyst work, we highlight the most important rules and offer visualization techniques in both spatial and temporal dimensions. Results have been verified to be helpful to recognize common situations and identify possible future anomalies.

Самостійна робота – запорука ефективності дистанційного навчання

As the title implies, the article reveals the issue of students’ self-learning within the framework of distance learning, which is aimed at providing efficient  self – educational and cognitive activity of students with the use of modern distance learning  educational telecommunication networks during the process of training.It is especially emphasized that the basis of distance learning is communication between a teacher and a student in an appropriate network of information and communication. It is stressed that  the  ability to learn  independently, which involves self-learning of students and an  individual approach of teachers  is becoming more and more popular nowadays.It is specially noted that self-learning efficiency requires skilled scientific and methodological support. It should be understood that it is the process of students’  heoretical material  mustering under the guidance of tutors that is of great importance. On its basis the choice of the model of students’ educational activity, design and implementation of educational tasks is carried out. It is worth noting that there are three levels of students’ self-learning activity: reproductive (training), which involves independent modelled work , reconstructive (partially searchable), which is associated with the transformation of the proposed content, and creative (search) level, requiring skills for problem statement and analysis of the problem situation. What is more, one of the types of students’ research activities is the project that promotes the formation of independent thinking and the implementation of a creative approach to solve  search problems . It should be stressed that the student's activity varies in the direction from gaining knowledge to its search. A student becomes the main subject of distance learning. However,it is reported that there is a problem of identifying the learner in knowledge assessment and monitoring, which is still not completely resolved. Therefore, this issue  remains open. It is noted that in order to avoid fictitious education received through distance learning, this issue needs to be given special attention. The directions of further scientific research of the mentioned problem are determined.
Cross Connected Network for Efficient Image Recognition

In this work, we describe a novel and highly efficient convolutional neural network for image recognition, which we term the “Cross Connected Network” (CrossNet). We have creatively introduced the Pod structure, where the feature map of depthwise convolutions can be reused within the same Pod by cross connection. Such a design can make the CrossNet have high performance while less computing resource, especially suitable for mobile devices with very limited computing power. Additionally, we find that depthwise convolutions with large receptive field has better accuracy/computation trade-offs, and further improves CrossNet performance. Our experiments on ImageNet classification and MSCOCO object detection demonstrate that CrossNet can improve the state-of-the-art performance of lightweight networks (such as MobileNets-V1/-V2, ShuffleNets and CondenseNet). We have tested the actual inference time on an ARM-based mobile device. The CrossNet still gets the best performance. Code and models are public available ( https://github.com/soeaver/CrossNet-PyTorch ).
Towards the Sustainable Development Goals in Africa: The African Space-Education Ecosystem for Sustainability and the Role of Educational Technologies

The United Nations Sustainable Development Goals (SDGs) encapsulate the collective desire of the world to eliminate the worst miseries of poverty and to set itself on a sustainable growth path. This chapter considers the origin of sustainable development in global discourse, and unpacks its education-related goals and targets. The specific focus is placed on tertiary education and it is argued that the SDGs depend on both regional and national strategies to succeed. Related questions of educational quality, and the role of Information and Communications Technology (ICT), are considered. The progress of the education-related SDGs is investigated, especially in relation to Internet and mobile phone penetration in Africa, and tertiary enrolment rates. ICTs, and specifically e-learning, are discussed as a means of helping the challenges related to the massification of the tertiary education sector in Africa. The way in which space supports education is considered as only one pillar of what in reality is an interrelated symbiotic relationship, which feeds back into producing space-related skills to advance the African space sector. Recommendations in light of space, education, and sustainable e-learning are discussed, and the importance of recognising the value of space in achieving the SDGs is emphasised.

Service Innovation and Performance of Telecommunication Firms in FCT, Abuja

Purpose: The current study conducts a literature review on service innovation and firm performance in telecoms with a view to develop a synthesis of commentaries on the concept, theoretical underpinnings and empirical evidences from previous studies as a planning phase or guide for future research. Methodology: A literature review approach was adopted to identify commentaries on service innovation and performance in service centric firms through a meticulous synthesis of information gotten from the articles adopted in the study. Findings: The findings of this study provides recent update on service innovation and performance of firms in telecoms, following the phenomenal growth and contributions of Information and Communication Technology [ICT] in global economies, with the primary focus of the review on demystifying the concept, dimensions, indicators, theories and empirical evidences. Three [3] major gaps in literature emphasizing geographical spread, methodology and scanty discourse on service centric firms were identified as justification that would permit further empirical tests. Research limitations: The review to a large extent focuses on service centric firms particularly those in telecoms. This limits generalization of the review to other industry and contexts. Practical implications: The several revelations of this study would look to guide future studies on the course of service innovation and performance of firms in telecom bearing in mind the specificities in the sector. Originality/value: This study addresses the daunting task of focusing on service-oriented innovations and firm performance in the service industry through its inclination to the demarcation perspective in examining telecommunication firms.

ЭЛЕМЕНТЫ ИНТЕЛЛЕКТУАЛЬНОЙ ДРАМЫ В РОМАНЕ ГАРОЛЬДА ПИНТЕРА «КАРЛИКИ»

Ksenia V. Arzhantseva, Vera B. Shamina (Kazan', Russian Federation) This article deals with the analysis of narrative structure of British dramatist Harold Pinter’s novel ‘The dwarfs’ in the context of intellectual drama tradition reconstruction. Through the analysis of the main characters of the novel the author has made an attempt to trace the key peculiarities of Pinter’s style. In Russian criticism there are very few works on the novel, mainly due to the fact that it was translated only 16 years after its publication. The processes, typical of new drama and literature on the turn of XXth and XXIst centuries, are also in the focus of this paper. ‘The dwarfs’ written in the early 1950s yet contains the characteristics of the playwright’s style, which have become his hallmarks. The principles, distinguished as attributive of intellectual drama, include dialogization as principal narrative form; thematization of theatre and art as method to objectify the aesthetic and philosophical conception of the author; remarks and intertextuality as form of interaction with the text, where the role of the author is applied to narrator-director. Key words: dwarfs, dialogization, intertextuality, intellectual drama, new drama, mask, play. DOI 10.23683/1995-0640-2019-1-177-185
Efficiency Analysis of Hybrid Fuzzy C-Means Clustering Algorithms and their Application to Compute the Severity of Disease in Plant Leaves

Data clustering has a wide range of application varying from medical image analysis, social network analysis, market segmentation, search engines, recommender systems and image processing. A clustering algorithm should be fast as well accurate. Some applications give priority to the speed of the clustering algorithms while some emphasize more on the accuracy rather than speed. A number of clustering algorithms have been proposed in the literature. Some of these include Fuzzy C-Means (FCM), Intuitionistic Fuzzy C-Means (IFCM), Rough Fuzzy C-Means (RFCM) and Rough Intuitionistic Fuzzy C-Means (RIFCM). In this paper, we compare the accuracy and execution time of the fuzzy based clustering algorithms. The clustering algorithms are applied on an image dataset and their running time as well as accuracy is compared by varying the number of clusters. Our results show that there is a clear trade-off between execution time and accuracy of these clustering algorithms. Also, we apply these algorithms on two different diseased leaf images and compute the severity of the disease of the leaves.
