    Due to global climate change, sea level rise (SLR) has become a threat for future generations, but the extent of this danger is unknown. To help understand the possible effects of SLR on the east coast of the United States, we studied three national parks: Acadia National Park (ACAD), Assateague Island National Seashore (ASIS) and Everglades National Park (EVER). We predicted that ACAD would be less affected by SLR than ASIS and EVER due to the construction of its beach profile. By measuring the beach profile, we found that Sand Beach in ACAD was reflective with an average slope of 3.2 cm/m while South Ocean Beach in ASIS had an intermediate morphology with an average slope of 1.57 cm/m. The Snake Bight Channel beach in EVER was dissipative and had no slope. Using historical Landsat imagery from 1984 to 2016, we estimated that ACAD’s water area increased by 1.61%, that ASIS’s water area increased by 2.47%, and that the EVER’s water area decreased by 0.22% between 1992 and 2011. Using RCP scenarios from the latest IPCC report, we estimated future inundation levels in each park along with the percent change between the best and worst-case scenarios. Under the RCP8.5 scenario, ACAD had 1.36 km2 of inundation, ASIS had 37.11 km2, and EVER had 366.47 km2. ACAD had the highest percent change between the worst and best RCP scenario at 15.70%. ASIS had a slightly smaller percent change at 14.25% and EVER had even less at 10.42%. This study suggests that continued SLR will cause national parks billions of dollars in property damage and the loss of their inherent ecological value

    Variation in pelvic morphology may prevent the identification of anterior pelvic tilt

    Pelvic tilt is often quantified using the angle between the horizontal and a line connecting the anterior superior iliac spine (ASIS) and the posterior superior iliac spine (PSIS). Although this angle is determined by the balance of muscular and ligamentous forces acting between the pelvis and adjacent segments, it could also be influenced by variations in pelvic morphology. The primary objective of this anatomical study was to establish how such variation may affect the ASIS-PSIS measure of pelvic tilt. In addition, we also investigated how variability in pelvic landmarks may influence measures of innominate rotational asymmetry and measures of pelvic height. Thirty cadaver pelves were used for the study. Each specimen was positioned in a fixed anatomical reference position and the angle between the ASIS and PSIS measured bilaterally. In addition, side-to-side differences in the height of the innominate bone were recorded. The study found a range of values for the ASIS-PSIS of 0–23 degrees, with a mean of 13 and standard deviation of 5 degrees. Asymmetry of pelvic landmarks resulted in side-to-side differences of up to 11 degrees in ASISPSIS tilt and 16 millimeters in innominate height. These results suggest that variations in pelvic morphology may significantly influence measures of pelvic tilt and innominate rotational asymmetry

    As part of an international collaboration with the Geophysical Institute of the University of Alaska, we have developed two all-sky imagers (CRL-ASIs). A sensitivity calibration of the CRL-ASIs was performed using an integrating sphere belonging to the National Institute of Polar Research (NIPR). The two-dimensional sensitivities of the CRL-ASIs produced symmetrical distributions. Using this sensitivity data, we converted airglow/aurora images into two-dimensional distributions of absolute intensity. The sensitivity of the CRL-ASIs was measured for 13 wavelengths between 427.8 nm and 866.5 nm, and the relationship between the sensitivity and the wavelength was investigated for both imagers. The peak sensitivity occurred at about 550 nm

    Estimation of living body weight based on measurements of anterior superior iliac spine breadth and stature

    Get PDF
    Standard identification criteria for creating a decedent’s biological profile typically include ancestry, sex, age, and stature, but not body weight. Body weight information may not only assist in creating a more complete biological profile but may also provide insight into other forensic considerations, such as taphonomy and body transport and disposal. The current study seeks to establish multiple regression equations for the prediction of living body weight in skeletal remains. Specifically, the measurements of anterior superior iliac spine (ASIS) breadth and stature are assessed with regard to living weight. Research was carried out on both a skeletal sample and a living population sample of modern black and white Americans. This two-pronged approach was an attempt to identify possible difficulties encountered in using the ASIS/stature technique in a forensic setting. The skeletal sample consisted of 92 individuals with weight data, upon whom ASIS breadth measurements and stature estimations were carried out. Height, weight, and ASIS breadth were subsequently recorded for the living population sample of 85 individuals. Multiple regression analysis was performed on all subsamples showing significant correlations between weight and ASIS breadth and stature variables. Regression equations for weight prediction were then derived from the results of analyses. However, the resulting estimated weight values indicate that ASIS breadth and stature must account for more variation in weight if the technique is to be useful in forensic investigations

    Academic and Student Imformation (ASIS) was developed by Pusat Komputer in 1998 to help lecturers and Jabatan Hal Ehwal Akademik Universiti Utara Malaysla to process students' results. The purpose of this research is to develop a system that can be used together with ASIS to manage courses more systematically and to perform statistical analysis on the considered data. The system enables lecturers to create a workspace to input and edit assignments, quizzes, tests and final examination scores. The number of fields to store students' performance such as assignments, tests etc will be determined by the lecturer and the system will calculate automatically the contribution of each set of the data to the total coursework score and final score depending on the percentage specified. The list of students registered for the course will directly be retrieved from ASIS. Coursework and final examination score will be transferred online to ASIS at the end of semester. Besides that, it is noticed that ASIS database contains a lot of data that can be utilised to assist System Penasihatan Pelajar. Graphical user interfaces (GUI) of the system will be developed using Visual Basic meanwhile data will be processed by SAS

    The Ping-Pong Olympics of Antisuit Injunction in FRAND Litigation

    Get PDF
    In the past two years, antisuit injunctions (ASIs) and subsequent legal proceedings associated with standard-essential patents (SEPs) subject to fair, reasonable, and nondiscriminatory (FRAND) commitments have proliferated in multiple jurisdictions. This phenomenon reveals not only the transnational nature of technical standards and FRAND-encumbered SEPs but also the jurisdictional tension between different national courts. This Article explains the emergence of ASIs in FRAND scenarios and recent developments in six jurisdictions with major interests in standard development and adoption. Countries have developed different approaches to ASIs based on their own domestic rules and interests. We believe that to promote technical compatibility and international comity, it is necessary to facilitate legal compatibility between jurisdictions at the policy level. Currently, courts in multiple jurisdictions are competing to grant ASIs and anti-anti-suit injunctions (AASIs), leading to fragmented decisions and significant costs for global standardization. We propose to include an exclusive forum selection clause in the policy documents of standard-setting organizations (SSOs) to reduce undesirable transaction costs stemming from ASIs and subsequent legal actions. Our proposal is more realistic and cost-effective than others concerning FRAND dispute resolution

    This thesis describes first the general state of the art in Software Management and Distribution in large Organisations, entering then the specifics of CERN and its software management and distribution method for UNIX/Linux-based systems called ASIS. The advantages and shortcomings of ASIS in its state before 1997 are explained in detail. The redesign and rewrite of the ASIS software framework and its tools, for which the author spent 12 months at CERN, is the core part of the thesis. The main functionality enhancements include the design and implementation of a transaction-based system for validating changes to the ASIS software repository, and its fail-safe replication on local and remote sites. The new framework and these tools are currently in production at CERN and many other institutes
