The Sahidic Tripartite Isaiah: Origins and Transmission within the Coptic Manuscript Culture
No full textAbstract
This study shows that the book of Isaiah was sometimes divided by Coptic scribes into three parts, each of them being copied individually into a separate manuscript. By surveying the available evidence, the author argues that this practice originated in the 4th century CE and was in use until the 8th century CE. The origins and eventual disappearance of tripartite Isaiah must be connected with the transformations that affected Coptic codices and scribal traditions from late antiquity to the medieval period
Mitigating the effects of atmospheric distortion using DT-CWT fusion
No full textThis paper describes a new method for mitigating the effects of atmospheric distortion on observed images, particularly airborne turbulence which degrades a region of interest (ROI). In order to provide accurate detail from objects behind the distorting layer, a simple and efficient frame selection method is proposed to pick informative ROIs from only good-quality frames. We solve the space-variant distortion problem using region-based fusion based on the Dual Tree Complex Wavelet Transform (DT-CWT). We also propose an object alignment method for pre-processing the ROI since this can exhibit significant offsets and distortions between frames. Simple haze removal is used as the final step. The proposed method performs very well with atmospherically distorted videos and outperforms other existing methods

Corporate Responsibility and the Value of Value(s)
No full textIn this book, we ask readers to consider what value means in CSR (for business and society, both by drawing from the past and by looking into the future), where it comes from and how it is enacted (organizational legacies or managers’ values) and its purpose (communicative value, co-operation, community). The chapter introduces the idea of value from an economic perspective and then explores the integration of values at the core of ethical business practice and CSR activities. It also provides an overview of the chapters, including historical developments of value in CSR, how value is linked to a positive vision of the future and how it is communicated by a range of private and public organizations to various audiences. Finally, it explains how leaders’ values can drive responsible business practice and enhance social cohesion, solidarity and resilience in fractured and unequal communities
Planning and Real Time Control of a Minimally Invasive Robotic Surgery System
No full textThis paper introduces the planning and control software of a teleoperating robotic system for minimally invasive surgery. It addresses the problem of how to organize a complex system with 41 degrees of freedom including robot setup planning, force feedback control and nullspace handling with three robotic arms. The planning software is separated into sequentially executed planning and registration procedures. An optimal setup is first planned in virtual reality and then adapted to variations in the operating room. The real time control system is composed of hierarchical layers. The design is flexible and expandable without losing performance. Structure, functionality and implementation of planning and control are described. The robotic system provides the surgeon with an intuitive hand-eye-coordination and force feedback in teleoperation for both hands
