The CBR-LRI Dataset: Methods, Properties and Potential of Leximetric Coding of Labour Laws

Leximetric code coding methods are designed to analyze cross-national and inter-temporal variations in the content of legal legislation, thereby facilitating statistical investigation of legal systems and their socioeconomic and economic impacts. In this article, we discuss how leximetric techniques were used to create the CBR Labor Regulation Index, an index and similar database of labour laws from around the world dating from 1970 to 2013. It should be made clear that the theoretical framework that undergirds the database's design and the types of questions it is supposed to answer should be outlined. With these points in mind, we provide an overview of the CBR-LRI survey's key elements and structure, address issues of weighting, and present some preliminary results on labor market trends around the world.

Relative Kinematic Orbit Determination for GRACE-FO Satellite by Jointing GPS and LRI

As the first in-orbit formation satellites equipped with a Laser Ranging Interferometer system, Gravity Recovery and Climate Experiment Follow-on satellites are designed to test the efficiency of the new LRI ranging technology used to satellite-to-satellite tracking, as the first in-orbit formation satellites equipped with a Laser Ranging Interferometer device, as the first in-orbit formation satellites equipped with a Laser Ranging Interferometer unit. A relative kinematic orbit determination scheme for formation satellites integrating Kalman filters and GPS/LRI is suggested to assess the use of LRI in GRACE-FO. GPS and LRI technologies can reduce the effects of GPS measurement errors and improve orbit determination of the GRACE-FO satellites. The GPS/LRI observation model's linearization and the procedure of the GPS/LRI relative kinematic orbit determination are included in this article. GPS/LRI improves the accuracy of the relative kinematic orbit determination by GPS only by approximately 1 cm along X, Y, and Z directions, as well as around 1. 8 cm in 3D directions.

514 Audit to Assess Negative Appendicectomy Rate (NAR) in Adult Patients in The Leicester Royal Infirmary (LRI)

Objectives: Aim: Determine the NAR rate in Leicester Royal Infirmary and compare to the national average This was a retrospective review that included all patients admitted over a three-month period to the LRI with suspected appendicitis. In this regard, Objective 1 of 2 (NAR of 5) remains the most significant of Ultrasounds' conclusions, but in less than 70% of cases, the U. S. has a very low false-positive rate in appendicitis diagnosis.

Land Resource Inventory (LRI) for Sustainable Watershed Development-A Case Study of Bisarahalli-1 Microwatershed of Semiarid Region of Koppal District, Karnataka, India

In the central part of northern Karnataka's semiarid area of Koppal tal and district, a land resource inventory of Bisarahalli-1 microwatershed was discovered. Different operating scenarios were investigated in order to determine the most feasible management options. By interfacing land resource data with Remote Sensing, GIS, and GPS, various business scenarios were investigated in order to determine the most appropriate management options that would be most effective. This data handling system would be useful in making land use decisions and providing proactive assistance to farmers on a real-time basis to protect the integrity of natural resources.

Thermal Influence on the LRI Scale Factor

In this talk, we discuss the LRI scale factor's current status, as well as the LRI's thermal environment. A cross-calibration to the KBR range is used to determine the LRI scale factor and a time-tag offset by decreasing the difference between KBR and LRI range in the current SDS processing scheme for deriving the LRI scale factor. We use a LRI telemetry based model for the nominal laser frequency, which already reduced the LRI scale to below ±5-10-8 (8), but we do not discuss the features that occur on a 3-month time scale. With this tone error correction, the difference between LRI and KBR range can be reduced by around 60% at low frerquencies. Our aim is to develop a scale factor that can be used with LRI telemetry and temperature sensors.

The re-analysis on the raw data processing of KBR and LRI on GRACE-FO

Distance measurements between the two spacecraft are used by KBR and LRI, which is one of the most common measurements used for temporal gravity field retrieval. Although GRACE-FO Science Data System makes Level-1B data publicly available, it has been discovered that alternative Level-1B datasets may have enhanced gravity field measurements [1]. KBR and LRI's Level-1A data was re-processed to Level 1B using technology developed at IGG/Wuhan. The differences between IGG-KBR1B and SDS-KBR1B are about three orders of magnitude smaller than the instrument noise level for KBR. These phase shifts in the LRI phase measurements are mostly coincident with thruster activations, as shown by Abich [2]. Our study will explore the effects of various processing techniques of the raw data on post-fit residuals and gravity field recovery based on IGG-KBR1B and IGG-LRI1B datasets.

Application of ultra‐precise GRACE Follow-On LRI measurements for validation of the state-of-the-art static gravity field models and examination of sub-monthly time-variable gravity signals

The GRACE Follow-On satellite's test Laser ranging interferometer gives exact measurements of atellite range and the development of new, GRACE-FO data products. According to LRI's frequency-domain analysis, the signal is dominated by the Earth's static gravity field. In these models, subtle un-/mis-modeled static gravity signals can be found in both spatial and spatial domains, and, as a result, we can see how the next generation of gravity field models can be enhanced. We show how the high-frequency Argentine Gyre signal is fully captured by instantaneous LRI measurements by individual data arcs, but not in the monthly mean Level-2 data, using comparison of measured gravity change by LRI with synthetic gravity change from altimetry sea surface measurements.

Evaluation of the Time Varying Gravity Fields from GRACE Follow-On LRI Instrument

Science data has been collected on board of the GRACE Follow-On satellites since launching in June 2018. Despite the fact that the LRI unit, based on engineering principles developed for a future LISA mission, was primarily intended as a demonstration unit, it has far outsaeld the mission's needs and has delivered intersatellite ranging measurements with improved signal-to-noise ratios relative to the K-Band Ranging unit.

Results of fusion of LRI based attitude data in the attitude Kalman filter

LRI uses the beam steering system where the quick steering mirror is activated to account for the misalignment between the incoming and outgoing laser beams.  ; Here we present the first findings of a new attitude product, which are calculated from a combination of quick steering mirror measurements with the star cameras and IMU in the attitude kalman filter.   We also discuss the effect of these new combined attitude measurements on the gravity field solutions.
