Analysis on the Possibility of RISC-V Adoption

As the interface between hardware and software, Instruction Set Architectures (ISAs) play a key role in the operation of computers. While both hardware and software have continued to evolve rapidly over time, ISAs have undergone minimal change. Since its release in 2010, RISC-V has begun to erode the industry aversion to ISA innovation. Established on the principals of the Reduced Instruction Set Computer (RISC), and as an open source ISA, RISC-V offers many benefits over popular ISAs like Intel’s x86 and Arm Holding’s Advanced RISC Machine (ARM). In this literature review I evaluate the literature discussing: What makes changing Instruction Set Architectures difficultWhy might the industry choose to implement RISC-V When researching this topic I visited the IEEE (Institute of Electrical and Electronics Engineers), INSPEC (Engineering Village), and ACM (Association for Computing Machinery) Digital Library databases. I used the search terms, “RISC-V”, “Instruction Set Architecture”, “RISC-V” AND “x86”, and “RISC-V” AND “Instruction Set Architecture”. This literature review evaluates 10 papers on implementation of RISC-V. As this paper was intended to cover recent developments in the field, publication dates were limited to from 2015 to present

CARE-PACT: a new paradigm of care for acutely unwell residents in aged care facilities

Describes the Comprehensive Aged Residents Emergency and Partners in Assessment, Care and Treatment (CARE-PACT) program: a hospital substitutive care and demand management project that aims to improve, in a fiscally efficient manner, the quality of care received by residents of aged care facilities. Background Ageing population trends create a strong imperative for healthcare systems to develop models of care that reduce dependence on hospital services. People living in residential aged care facilities (RACFs) currently have high rates of presentation to emergency departments. The care provided in these environments may not optimally satisfy the needs of frail older persons from RACFs.   Objective To describe the Comprehensive Aged Residents Emergency and Partners in Assessment, Care and Treatment (CARE-PACT) program: a hospital substitutive care and demand management project that aims to improve, in a fiscally efficient manner, the quality of care received by residents of aged care facilities when their acute healthcare needs exceed the scope of the aged care facility staff and general practitioners to manage independently of the hospital system.   Discussion The project delivers high-quality gerontic nursing and emergency specialist assessment, collaborative care planning, skills sharing across the care continuum and an individualised, resident-focused approach

Dynamic Data Structures for Document Collections and Graphs

In the dynamic indexing problem, we must maintain a changing collection of text documents so that we can efficiently support insertions, deletions, and pattern matching queries. We are especially interested in developing efficient data structures that store and query the documents in compressed form. All previous compressed solutions to this problem rely on answering rank and select queries on a dynamic sequence of symbols. Because of the lower bound in [Fredman and Saks, 1989], answering rank queries presents a bottleneck in compressed dynamic indexing. In this paper we show how this lower bound can be circumvented using our new framework. We demonstrate that the gap between static and dynamic variants of the indexing problem can be almost closed. Our method is based on a novel framework for adding dynamism to static compressed data structures. Our framework also applies more generally to dynamizing other problems. We show, for example, how our framework can be applied to develop compressed representations of dynamic graphs and binary relations

Featured Piece

This year the General Editors decided to create a feature piece to show our appreciation for the History Department. We selected four professors from the faculty to answer a question about history: what figure/event/idea inspires your interest in history? Reading their responses helped give us insight into the thoughts of these brilliant minds and further help us understand their passion for the subject we all share a common love and interest in. We hope that you enjoy reading their responses as much as we did. The four members of the faculty we spoke with are Dr. Timothy Shannon, Dr. Ian Isherwood, Dr. Jill Titus, and Dr. Scott Hancock

Sylview: a visualization system for forest management

The entire dissertation/thesis text is included in the research.pdf file; the official abstract appears in the short.pdf file (which also appears in the research.pdf); a non-technical general description, or public abstract, appears in the public.pdf file.Title from title screen of research.pdf file (viewed on August 28, 2006)Includes bibliographical references.Thesis (M.S.) University of Missouri-Columbia 2006.Dissertations, Academic -- University of Missouri--Columbia -- Computer science.In the field of forestry, the output of forest growth models provide a wealth of detailed information that can often be difficult to analyze and perceive due to presentation either as plain text summary tables or static stand visualizations. This thesis describes the design and implementation of a cross-platform computer application for dynamic and interactive forest stand visualization, titled Sylview. Sylview allows users to visualize many aspects of forest stands from overall stand makeup to wood quality characteristics of individual trees. From these visualizations the user can infer the effects of different stand management practices. A primary focus in the design of the Sylview is usability. Sylview features a simple, interactive interface and intuitive visualizations focusing on legibility. As part of the development of Sylview a new data structure was designed for the efficient retrieval of required data, which will also be applied to future growth model development

Measurement of the elastoresistivity coefficients of the underdoped iron-arsenide Ba(Fe0.975_{0.975}Co0.025_{0.025})2_2As2_2

A new method is presented for measuring terms in the elastoresistivity tensor $m_{ij}$ of single crystal samples with tetragonal symmetry. The technique is applied to a representative underdoped Fe-arsenide, Ba(Fe$_{0.975}$Co$_{0.025}$)$_2$As$_2$, revealing an anomalously large and anisotropic elastoresistance in comparison to simple metals. The $m_{66}$ coefficient follows a Curie-Weiss temperature dependence, providing direct evidence that the tetragonal-to-orthorhombic structural phase transition that occurs at $T_s$ = 97.5 K in this material is not the result of a true-proper ferro-elastic transition. Rather, the material suffers a pseudo-proper transition for which the lattice strain is not the primary order parameter
