Modelling, Dimensioning and Optimization of 5G Communication Networks, Resources and Services
This reprint aims to collect state-of-the-art research contributions that address challenges in the emerging 5G networks design, dimensioning and optimization. Designing, dimensioning and optimization of communication networks resources and services have been an inseparable part of telecom network development. The latter must convey a large volume of traffic, providing service to traffic streams with highly differentiated requirements in terms of bit-rate and service time, required quality of service and quality of experience parameters. Such a communication infrastructure presents many important challenges, such as the study of necessary multi-layer cooperation, new protocols, performance evaluation of different network parts, low layer network design, network management and security issues, and new technologies in general, which will be discussed in this book
Applications
Volume 3 describes how resource-aware machine learning methods and techniques are used to successfully solve real-world problems. The book provides numerous specific application examples: in health and medicine for risk modelling, diagnosis, and treatment selection for diseases in electronics, steel production and milling for quality control during manufacturing processes in traffic, logistics for smart cities and for mobile communications
Ribosomes as Sensors: How Cells Utilize the Translational Process to Monitor Cellular Conditions
The discovery that collisions between ribosomes are the key signaling event that triggers quality control and stress response pathways in eukaryotes has changed our understanding of how cells sense and respond to the environment. Collided eukaryotic ribosomes adopt a unique structure, providing a mechanistic basis for how environmental signals can be sensed by the translational machinery and propagated into wider reprogramming of gene expression. Indeed, the use of ribosomes as a signaling hub is quite apt, as ribosomes make intimate contact with both mRNA and tRNAs. This enables them to monitor the integrity of genetic information coming from the nucleus while simultaneously checking the availability of cellular resources, acting as a sentinel of the central dogma of biology. Here, we discuss the ribosome in the context of the broader translational cycle and how signals arise from disruptions to ribosome function. We also discuss the effects of modifications to the mRNA on the ribosome and the role of the ribosome in the response
Metode Applied Behavior Analysis Untuk Meningkatkan Kontak Mata Pada Anak Dengan Autism Spectrum Disorder
Kontak mata terjadi di awal perkembangan dan memiliki banyak fungsi bagi perkembangan
kehidupan. Dengan adanya kontak mata dapat mengembangkan keterampilan yang lebih
kompleks, seperti keterampilan sosial, kognitif, dan bahasa. Namun sejumlah besar anak
dengan Autism Spectrum Disorder (ASD) gagal mengembangkan keterampilan kontak mata
yang penting ini. Kegagalan anak ASD dalam mengembangkan kontak mata tersebut,
menyebabkan aktivitasnya terganggu, baik dalam belajar maupun kehidupan sosial. Salah
satu metode efektif digunakan untuk meningkatkan kontak mata anak dengan ASD adalah
Applied Behavior Analysis (ABA). Metode tersebut terstruktur, mudah diukur, dan didesain
khusus bagi anak dengan spectrum autis. Tujuan dari penelitian ini untuk mengetahui adakah
pengaruh Metode ABA dalam meningkatkan kontak mata anak dengan ASD. Penelitian ini
menggunakan metode eksperimen Single Case Experimental Design dengan desain A-B.
Subjek dari penelitian ini yaitu seorang anak laki-laki berusia 7 tahun dengan ASD kategori
sedang. Alat ukur dalam penelitian ini menggunakan checklist. Analisis data statistik yang
digunakan dalam penelitian ini adalah analisis dengan grafik. Hasil penelitian menunjukkan
metode ABA dapat meningkatkan kontak mata anak dengan ASD

Examining university student satisfaction and barriers to taking online remote exams
Recent years have seen a surge in the popularity of online exams at universities, due to the greater convenience and flexibility they offer both students and institutions. Driven by the dearth of empirical data on distance learning students' satisfaction levels and the difficulties they face when taking online exams, a survey with 562 students at The Open University (UK) was conducted to gain insights into their experiences with this type of exam. Satisfaction was reported with the environment and exams, while work commitments and technical difficulties presented the greatest barriers. Gender, race and disability were also associated with different levels of satisfaction and barriers. This study adds to the increasing number of studies into online exams, demonstrating how this type of exam can still have a substantial effect on students experienced in online learning systems and
technologies
Economic Token To Improve On-Task Behavior In Children With Attention Deficit Hyperactivity Disorder
Memusatkan perhatian pada tugas atau perilaku on-task merupakan salah satu keterbatasan
yang dimiliki oleh anak dengan Attention Deficit Hyperactivity Disorder. Pada sisi lain,
perilaku on-task ini seharusnya dimiliki oleh anak usia sekolah. Tujuan dari penelitian ini
adalah meningkatkan durasi perilaku on-task pada anak dengan gangguan Attention Deficit
Hyperactivity Disorder dengan menggunakan teknik token ekonomi. Desain eksperimen
yang digunakan adalah single subject design model A-B-A. Intervensi dilakukan selama 10
kali pertemuan. Partisipan yang digunakan dalam penelitian ini adalah anak dengan
gangguan Attention Deficit Hyperactivity Disorder yang berusia 9 tahun 9 bulan.
Pengumpulan data dilakukan menggunakan observasi pada durasi perilaku on-task anak
ketika mengerjakan tugas. Analisis data menggunakan analisis grafik. Efek dari intervensi
dapat dilihat dari grafik durasi perilaku on-task yang diukur pada fase baseline 1, fase
intervensi dan fase baseline 2. Hasil penelitian menemukan bahwa teknik token ekonomi
mampu meningkatkan durasi perilaku on-task pada anak dengan Attention Deficit
Hyperactivity Disorder
