Pulsar: Design and Simulation Methodology for Dynamic Bandwidth Allocation in Photonic Network-on-Chip Architectures in Heterogeneous Multicore Systems

As the computing industry moved toward faster and more energy-efficient solutions, multicore computers proved to be dependable. Soon after, the Network-on-Chip (NoC) paradigm made headway as an effective method of connecting multiple cores on a single chip. These on-chip networks have been used to relay communication between homogeneous and heterogeneous sets of cores and core clusters. However, the variation in bandwidth requirements of heterogeneous systems is often neglected. Therefore, at a given moment, bandwidth may be in excess at one node while it is insufficient at another leading to lower performance and higher energy costs. This work proposes and examines dynamic schemes for the allocation of photonic channels in a Photonic Network-on-Chip (PNoC) as an alternative to their static-provision counterparts and proposes a method of simulating and selecting the characteristics of a dynamic system at the time of design as to achieve maximum system performance in a Photonic Network-on-Chip for a given application type

Simulation of Human and Artificial Emotion (SHArE)

The framework for Simulation of Human and Artificial Emotion (SHArE) describes the architecture of emotion in terms of parameters transferable between psychology, neuroscience, and artificial intelligence. These parameters can be defined as abstract concepts or granularized down to the voltage levels of individual neurons. This model enables emotional trajectory design for humans which may lead to novel therapeutic solutions for various mental health concerns. For artificial intelligence, this work provides a compact notation which can be applied to neural networks as a means to observe the emotions and motivations of machines

Magnetic Resonance Imaging (MRI) Utilization in a Ghanaian Teaching Hospital: Trend and Policy Implications

Background: The use of Magnetic Resonance Imaging (MRI) is new in Ghana compared with some Western countries.A number of studies have observed increased MRI utilization due to increased sensitivity to diagnosis, and the paradigm shift to modalities that do not use radiation. Challenges with MRI use include high cost of the examination and inappropriate requests by referring clinicians. Objective: To determine the MRI utilisation trend in Korle Bu Teaching Hospital (KBTH), Ghana and its policy implications. Materials and Methods: A retrospective study undertaken in the Radiology Department, KBTH, from February to March, 2017. Eight hundred and forty request forms for MRI studies between January, 2013 and December 2016 were reviewed. Information on patient’s age and sex, number of MRI studies done, body parts and clinical conditions evaluated, appropriateness of clinical requests and existing policies on MRI in Ghana was gathered. Measures of central tendency and spread were obtained. Chi square, Pearson’s correlation and linear regression analysis were also used in the analysis. Results: The top three body parts requested were Spine (55 %), Brain (19%) and Joints (6 %); degenerative disease was the most common clinical condition evaluated.Significant association and correlation were obtained between of the number of body parts evaluated and examination year as well as the variety of clinical conditions requested and examination year. Conclusion: A progressive increase was noted in MRI utilisation both in number and diversity but no policy guiding MRI use in Ghana exists

ICT integration in teaching and learning: Perceptions and practices in Ghanaian college of education

This research study investigates the perceptions and practices of Information and Communication Technology (ICT) integration in teaching and learning within Ghanaian Colleges of Education. With the increasing recognition of ICT as a valuable tool in education, it is crucial to understand how these technologies are being utilized in the context of teacher training institutions, specifically in Ghana. The research employs a qualitative data collection method. Semi-structured interviews were conducted to gather comprehensive insights into the perceptions and practices of ICT integration among college faculty and students. The participants include teacher educators, and pre-service teachers in Ghanaian College of Education. Through thematic analysis, the qualitative data provide a deeper understanding of various stakeholders' attitudes, beliefs, and perceptions toward ICT integration. The findings of this study contribute to the existing body of knowledge on ICT integration in teaching and learning in Ghanaian College of Education. It will shed light on the current practices, challenges faced, and potential opportunities for improvement. The research outcome can inform policy decisions, curriculum development, and professional development initiatives to enhance ICT integration within teacher training programs in Ghana. By addressing the perceptions and practices surrounding ICT integration, this study aspires to support the transformation of teacher education, leading to more proficient and technologically equipped educators prepared for the 21st-century classroom challenges
