Proactive Handoff of Secondary User in Cognitive Radio Network Using Machine Learning Techniques

2021

Spectrum management always appears as an essential part of modern communication systems. Handoff is initiated when the signal strength of a current user deteriorates below a certain threshold. In cognitive radio network, the perception of handoff is different due to the presence of two categories of users: certified/primary user and uncertified/secondary user. The reason for the spectrum handoff arises when the primary user (PU) returns to one of its band used by the secondary user. The spectrum handoff is of two types: reactive handoff and proactive handoff. There are certain limitations in reactive handoff, such as it suffers from prolonged handoff latency and interference. In the proacti…

An Integrated Wireless Communication Architecture for Maritime Sector

2011

Published version of a chapter in the book: Multiple Access Communications. Also available from the publisher at http://dx.doi.org/10.1007/978-3-642-23795-9_17 The rapid evolution of terrestrial wireless systems has brought mobile users more and more desired communication services. Maritime customers are asking for the same, such as the concepts of “Broadband at Sea” and “Maritime Internet”. Quite a lot of research work has focused on the development of new and better maritime communication technologies, but less attention has been paid on interworking of multiple maritime wireless networks or on satisfying service provisioning. To address this, an integrated wireless Communication Architec…

Masked form priming in writing words from pictures: evidence for direct retrieval of orthographic codes.

1998

Three experiments used the masked priming paradigm to investigate the role of orthographic and phonological information in written picture naming. In all the experiments, participants had to write the names of pictures as quickly as possible under three different priming conditions. Nonword primes could be: (1) phonologically and orthographically related to the picture name; (2) orthographically related as in (1) but phonologically related to a lesser degree than in (1); (3) orthographically and phonologically unrelated except for the first consonant (or consonant cluster). Orthographic priming effects were observed with a prime exposure duration of 34 ms (Experiments 1 and 2) and of 51 ms …

The role of success expectation and task-avoidance in academic performance and satisfaction: Three studies on antecedents, consequences and correlates

2003

Abstract To investigate the prospective relationships between individuals’ success expectation and task-avoidance, and their academic achievement and satisfaction, 231 students were examined yearly throughout their university careers in Study 1. It was found that students’ success expectation predicted academic achievement and satisfaction; which, in turn, increased their subsequent success expectation. Moreover, task-avoidance predicted low academic achievement and dissatisfaction, which again was predictive of subsequent task-avoidance. In Study 2, the task-avoidant behavior, and pre-examination anxiety, of 198 students who had participated in Study 1 were examined, and compared with thei…

Analytic second derivatives for general coupled-cluster and configuration-interaction models.

2004

Analytic second derivatives of energy for general coupled-cluster (CC) and configuration-interaction (CI) methods have been implemented using string-based many-body algorithms. Wave functions truncated at an arbitrary excitation level are considered. The presented method is applied to the calculation of CC and CI harmonic frequencies and nuclear magnetic resonance chemical shifts up to the full CI level for some selected systems. The present benchmarks underline the importance of higher excitations in high-accuracy calculations.

Experiences of using the ISBAR tool after an intervention: A focus group study among critical care nurses and anaesthesiologists.

2021

Objective The ISBAR tool is a structured approach to communication between healthcare professionals and refers to Identity, Situation, Background, Assessment, and Recommendation. The objective of this study was to explore how critical care nurses and anaesthesiologists experience using the ISBAR tool in clinical practice. Design Three focus groups were conducted with a total of three anaesthesiologists and 14 critical care nurses from two hospitals in Norway after they had attended an intervention. Setting The intervention consisted of two days at a university, with a four-month interval between, attending resource lectures and simulation exercises focusing on the ISBAR tool. The focus grou…

Mutual intelligibility among the sign languages of Belgium and the Netherlands

2015

AbstractIn an exploratory study of mutual intelligibility between the sign languages of the northern part of Belgium (Flemish Sign Language, VGT), the southern part of Belgium (French Belgian Sign Language, LSFB), and the Netherlands (Sign Language of the Netherlands, NGT), we tested the comprehension of VGT by signers of LSFB and NGT. In order to measure the influence of iconic structures (classifier constructions and constructed action) that linguistic analyses have shown to be similar across different sign languages, two genres were compared: narrative and informative signing. To investigate the effect of the overlap between the spoken languages surrounding the Dutch and Flemish Deaf com…

New ways of looking into handwritten miscellanies of the seventeenth century: the case of “Spes Altera”

2020

A large number of copies of Shakespeare’s Sonnet 2 circulated in handwritten miscellanies from the second quarter of the Seventeenth Century. Eleven of those copies have significant variant readings that have led critics to put forward different hypotheses regarding their nature and quality. Most critics, taking into account stylometric analyses, have regarded them as early drafts of Shakespeare’s printed version, and have agreed on their poor quality.By paying due attention to the text’s context of production and reception, we have reached a different conclusion regarding both the nature and quality of the handwritten versions of Sonnet 2. In our view, they are the product of a conscious r…
