Risk of Increased Fragmentation Events Due to Low Altitude Large Constellation Spacecraft

Orbital debris experts and industry leaders are concerned about the added hazard that thousands of additional spacecraft would have on the future orbital debris environment. Large constellations proposals plan to deploy spacecraft at altitudes from 1100 km to 1300 km, where fragmentation debris can take thousands of years or longer to decay naturally, while other proposals include deploying spacecraft at station-keeping altitudes from 300 km to 600 km. Although these lower altitude spacecraft are compliant with the 25-year rule, there is still an increased risk of accidental explosions generating high velocity fragments that could damage international spacecraft assets. The NASA Orbital Debris Program Office (ODPO) has conducted several parametric studies that examine the potential negative environmental impacts of large constellation deployments. This study addresses the lower altitude constellations and the potential risk that they impose on the future environment during mission operations. The projected future environment is generated as the average of 100 LEGEND Monte Carlo (MC) simulation runs while adjusting parameters such as average probability of explosion and operational lifetime per constellation. Results of the effect of accidental explosions of large constellation spacecraft on the environment below 600 km altitude are analyzed

PENGARUH TINGKAT SUKU BUNGA PINJAMAN DAN JUMLAH DEPOSITO TERHADAP JUMLAH PENYERAPAN KREDIT BPR DI INDONESIA

ABSTRACT TISSA APRILIA. “The Influences of lending rate and time deposit against the Total Loan of BPR in Indonesia.” Thesis. The Education of Cooperation Economic. Economic and Administration Major. Faculty of Economic. State University of Jakarta. 2013. Lecturer Advisor : Dra. Rd. Tuty Sariwulan, M.Si. dan Dr. Haryo Kuncoro, S.E, M.Si. This research is purposed to analyze the influence of lending rate and time deposit against the total loan of BPR in Indonesia. The data used in this research are the secondary data, that type of pooled data for 2010-2012 periods, presented in annual data, source from DKBU BI. The methods of this research are expose facto. The technique of data analysis in this research is the multiple regression analysis. Based on multiple regressions by using Eviews 7.2 software, the output has indicated the lending rate (X1) is negatively and not significant affected to the total loan of BPR (Y) in Indonesia. While, the time deposit (X2) is positively and significantly affected to the total loan of BPR (Y) in Indonesia. Based on the test with respect to F significant value = 0,0000<0,05, it can concluded that the lending rate and time deposit is significantly affected on a = 5% against to the total loan of BPR in Indonesia. Determination coefficient value that obtained is 0,978, it means that the changes of total loan of BPR in Indonesia could be explained by the changes of the lending rate and time deposit as amount 97,8 %. While, the rest could be explained by others factor that can not mentioned in this research model. Keywords : Total Loan of BPR, Lending Rate, Time Deposit

Hasil analisa uji Mann-Whitney didapatkan ρ=0,003. H0 ditolak bila ρ<α, berarti ada hubungan tingkat pengetahuan dengan sikap ibu dalam pencegahan diaper rash pada bayi. Simpulan penelitian, semakin baik pengetahuan maka akan positif sikap ibu untuk mencegah diaper rash. Petugas kesehatan diharapkan lebih meningkatkan promosi kesehatan tentang diaper rash

The Updated GEO Population for ORDEM 3.1

The limited availability of data for satellite fragmentations and debris in the geosynchronous orbit (GEO) region creates challenges to building accurate models for the orbital debris environment at such altitudes. Updated methods to properly incorporate and extrapolate measurement data have become a cornerstone of the GEO component in the newest version of the NASA Orbital Debris Engineering Model (ORDEM), ORDEM 3.1. For the GEO region, the Space Surveillance Network (SSN) catalog provides coverage down to a limit of approximately 1 m. A more statistically complete representation of the GEO population for smaller objects, which can pose a high risk to operational spacecraft, is thus dependent on dedicated observations by instruments optimized to observe debris smaller than the SSN cataloging threshold. For ORDEM 3.1, optical data from the Michigan Orbital DEbris Survey Telescope (MODEST) provided the input for building the GEO population down to approximately 30 cm (converting absolute magnitude to size). For smaller sizes, the size distribution of debris in the MODEST dataset was extrapolated down to 10 cm, and orbital parameters were estimated based on the orbits of the larger objects. When compared to previous versions of the model, significant improvements were made to the process of building the GEO population in ORDEM 3.1, both in the assessment of fragmentation debris in the data and assignment of orbital elements within the model. A so-called debris ring filter, based on a range of angles between an orbits angular momentum vector and that of the stable Laplace plane, was applied to the data to reduce biases from non- GEO objects, such as objects in a GEO-transfer orbit. In addition, a new approach was implemented to assign noncircular mean motions and eccentricities to the fragmentation debris observed by MODEST because the short observation window (5 min) in GEO limits orbit resolution to a circular orbit assumption for assigning orbital parameters. For ORDEM 3.1, non-circular orbital elements were assigned using relationships that were identified between mean motion and the angle between the orbit plane and the stable Laplace plane, as well as between mean motion and eccentricity, based on breakup clouds modeled by the NASA Standard Breakup Model. This approach has yielded a high-fidelity GEO model that has been validated with data from more recent MODEST observation campaigns

Climate change and extreme wind effects on transmission towers

Climate change poses a major threat to electricity power infrastructure due to expected increases in the magnitude and frequency of extreme storm events. This paper uses a methodology for assessment of the vulnerability of UK transmission tower infrastructure to such events, within a framework of performance-based engineering. The challenge of estimating future storm magnitudes is addressed by applying a change factor methodology to present-day wind speeds using information provided by the 2009 UK climate change projections. A Weibull distribution is employed to obtain wind speeds for storm events at different recurrence intervals. Wind loading on the structure and cables is then determined using Eurocodes, and the structure is analysed using pseudo-static finite-element analysis, considering material and geometrical non-linearity as well as linear and non-linear buckling effects. The outcome of the research is that, despite a significant projected increase in wind velocities due to climate change, the typical tower analysed in the study continues to perform satisfactorily at all hazard levels. If this performance can be demonstrated more generally across the UK transmission tower infrastructure network, then it is likely that the cause can be traced back to the high factor of safety applied in the original design of the towers

Spectral Lags Explained as Scattering from Accelerated Scatterers

A quantitative theory of spectral lags for $\gamma$-ray bursts (GRBs) is given. The underlying hypothesis is that GRB subpulses are photons that are scattered into our line of sight by local concentrations of baryons that are accelerated by radiation pressure. For primary spectra that are power laws with exponential cutoffs, the width of the pulse and its fast rise, slow decay asymmetry is found to increase with decreasing photon energy, and the width near the exponential cutoff scales approximately as $E_{ph}^{-\eta}$, with $\eta\sim 0.4$, as observed. The spectral lag time is naturally inversely proportional to luminosity, all else being equal, also as observed.Comment: 2 figure
