QoS-Constrained Semi-Persistent Scheduling of Machine-Type Communications in Cellular Networks
Authors:
Publisher and Date:(IEEE, 2019)The dramatic growth of machine-to-machine (M2M) communication in cellular networks brings the challenge of satisfying the quality of service (QoS) requirements of a large number of M2M devices with limited radio resources. In this paper we propose an optimization framework for the semi-persistent scheduling of M2M transmissions based on the exploitation of their periodicity with the goal of reducing the overhead of the signaling required for connection initiation and scheduling. The goal of the ...

A qualitative analysis of data journalism practice in Turkey
Authors:
Publisher and Date:(Kadir Has University, 2017)The importance of data in the field of communication is increasing day by day; the usage of data in the media/news called as data journalism which produces news with data. There are many theses and academic articles on journalism and media studies, but the studies conducted in the sense of data journalism are limited. Despite resource constraints, it is important to work in the field of data journalism and provide resources for literature which has limited resource. The aim of this study is to ...

Quantile Estimates for Social Returns to Education in Turkey: 2006–2009
Authors:
Publisher and Date:(Routledge, 2013)Augmenting a Mincerian earnings function with regional data we estimate both private and external returns to education in Turkey using Instrumental Variables, Ordinary Least Squares, Quantile Regression and Instrumental Variables Quantile Regression methods. Our results indicate a median external return between 1.5% and 2.3% for 2006–2009. There is some evidence supporting the skill-biased technical change hypothesis. External returns are uniformly higher for women. We point out some policy implications.

R&D Activity and Financing Constraints: Evidence from Turkey
Authors:
Publisher and Date:(Savez Ekonomista Vojvodine, 2020)We analyze the relationship between financing constraints and firms' R&D activity using a rich and comprehensive firm-level balance sheet and income statement data set of manufacturing firms in Turkey for the period 1996 to 2013. Using a firm-specific, time-varying financing constraints index, we find that financing constraints have a negative relationship with firms' R&D activity, after controlling for other determinants of R&D such as firm size, capital intensity and export market participation.

Radio frequency identification system optimisation models for lifecycle of a durable product
Authors:
Publisher and Date:(Taylor & Francis Ltd, 2010)We address the implementation of radio frequency identification (RFID) technology to support and manage durable products over their entire lifecycle with a focus on optimising the RFID tagging system. We develop general models that optimise the placement of RFID tags on an end product and its components the allocation of the data on tags and the selection of RFID tags and their configuration. The primary criteria for optimisation are to maximise the value of RFID data and to minimise the total ...

Railway heritage of Istanbul and the Marmaray Project
Authors:
Publisher and Date:(Taylor & Francis Inc, 2012)This study explores the significance of Istanbul's railway heritage and discusses the criteria for evaluating the historical importance architectural value and social issues surrounding the city's rail system leading into an examination of the consequences of the Marmaray Project. The Marmaray Project is a commuter rail system designed to unify Istanbul's two independent rail transportation systems and it will connect Halkali on the European side with Gebze on the Asian side of the city. With the ...

Random CapsNet forest model for imbalanced malware type classification task
Authors:
Publisher and Date:(Elsevier, 2021)Behavior of malware varies depending the malware types, which affects the strategies of the system protection software. Many malware classification models, empowered by machine and/or deep learning, achieve superior accuracies for predicting malware types. Machine learning-based models need to do heavy feature engineering work, which affects the performance of the models greatly. On the other hand, deep learning-based models require less effort in feature engineering when compared to that of the ...

Ranking Protein-Protein Binding Using Evolutionary Information and Machine Learning
Authors:
Publisher and Date:(Association for Computing Machinery, 2017)Discriminating native-like complexes from false-positives with high accuracy is one of the biggest challenges in protein-protein docking. The relationship between various favorable intermolecular interactions (e.g. Van derWaals electrostatic desolvation forces etc.) and the similarity of a conformation to its native structure is commonly agreed though the precise nature of this relationship is not known very well. Existing protein-protein docking methods typically formulate this relationship as a ...

Rape comparative study on feminist perspectives privileged feminists black feminists and Turkish feminists
Authors:
Publisher and Date:(Kadir Has University, 2006)Is it possible to assume that “rape” has one specific determination? Is it possible to find different definitions of rape around the world? If women are most frequently victims of rape, is it about being women? Is there a relationship between gender asymmetry and rape in society? Can culture, ethnicity, race, class or gender make a difference while determining the crime? Is it only a crime? Can the perception of such a crime make difference depending on where you stand? How do women perceive ...

Rapidly Time-Varying Channel Estimation for Full-Duplex Amplify-and-Forward One-Way Relay Networks
Authors:
Publisher and Date:(IEEE-INST Electrical Electronics Engineers Inc, 2018)Estimation of both cascaded and residual self-interference (RSI) channels and a new training frame structure are considered for full-duplex (FD) amplify-and-forward (AF) one-way relay networks with rapidly time-varying individual channels. To estimate the RSI and the rapidly time-varying cascaded channels we propose a new training frame structure in which orthogonal training blocks are sent by the source node and delivered to the destination over an FD-AF relay. Exploiting the orthogonality of the ...

Rapidly Varying Sparse Channel Tracking with Hybrid Kalman-OMP Algorithm
Authors:
Publisher and Date:(Springer, 2019)It is expected from future communication standards that channel estimation algorithms should be able to operate over very fast varying frequency selective channel models. Therefore in this study autoregressive (AR) modeled fast varying channel has been considered and tracked with Kalman filter over one orthogonal frequency division multiplexing (OFDM) symbol. Channel sparsity is exploited which decreases the complexity requirements of the Kalman algorithm. Since Kalman filter is not directly ...

Re-Considering The Linkage Between The Antecedents and Consequences of Happiness
Authors:
Publisher and Date:(Elsevier Science Bv, 2016)A growing number of studies examine the antecedents of happiness but only a handful of them appear to undertake an analysis of its consequences. Employing a unique cross-sectional data set of 413 adults we examine the relationship of the antecedents of happiness on its outcomes via mediation analysis. We show that the web of relations in this domain is more complicated than it is commonly understood. We provide empirical evidence that income enhances individuals' life satisfaction. We also find a ...
