Tasking Framework: Parallelization of Computations in Onboard Control Systems

For the next generation of onboard computer in space application a high demand on processing power exists. Currently used onboard system didn't provide the necessary computing power. The in the paper describe tasking frame work is the core processing model for the OBC-NG (On Board Computer - Next Generation) operating system with an reactive computing model

Parallelization of the AVL FIRE Benchmark with SVM-Fortran

This article outlines the parallelization of an irregular grid application with SVM-Fortran. It describes the different optimizations and their effectiveness. The parallelization was much simplified by the performance analysis tool OPAL, a source code based tool for requesting and analyzing runtime performance data. Although shared memory parallelization is easier than distributed memory parallelization, understanding and eliminating the overhead from page faults is impossible without such a tool. It relates the page faults to the arrays and to the location in the source code. An area which is not supported by OPAL but where supporting tools are highly desirable, is the performance degradation due to low utilization of the on-chip cache

Death Rates from Alzheimers

Since 1999, Alzheimer’s disease has become more of a talking point in our society. This could be because death by Alzheimer’s disease has increased gradually over the years in the United States (NCHS, 2022). We hypothesized that mortality rates due to Alzheimer’s disease will increase as life expectancy rises. This is due to the fact that individuals under the age of fifty-five are highly unlikely to develop this disease. The dataset we examined and analyzed, Leading Causes of Death, comes from the National Center for Health Statistics and showcases the causes of death in each state in America from 1999 to 2017. The dataset includes the year, cause of death, amount of deaths, and the age-adjusted death rate in each individual state. By comparing the rate of Alzheimer’s related deaths from 1999 versus 2017 we see a clear increase, especially in the southeastern region of the United States. There could be several cultural, economic, and environmental factors at play causing this phenomenon, such as the average population age being older in this specific region. Death by Alzheimer’s disease is rapidly increasing across the United States. How can we implement psychological programs within our older population to prevent the onset of this disease in the U.S.
