Thermal expansion anomalies of R(Fe, M)(12) (R=Y, Nd; M=Mo and Si)
No full textStructural and thermal-expansion anomaly studies on R(Fe,M)(12) (R=Nd and and Y, M=Mo and Si) compounds were performed by x-ray diffraction. Mo atoms occupy the 8i site. While Si atoms occupy the 8f and 8j sites but not the 8i site. Thermal-expansion anomaly shows only in ab plane in the Mo compounds, while becomes very weak and along with only the c axis in the Si compounds. The anomaly was attributed to the contribution of the interactions of short Fe-Fe distances similar to the previous explanation on other R-Fe intermetallics and that of other strongly positive interactions such as 8j-8j.

A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Liftings for noncomplete probability spaces

Adaptive pole assignment using an auto-recurrence model-based state feedback control scheme
No full textVita.A parameter control scheme is developed for control of a single-input single-output (SISO) process. An auto-recurrence model is used for the identification of structural and coefficient parameters. Adaptive model state feedback control is used based upon a pole-placement design. Around this, adaptive explicit Closed-Loop Model-Reset (C-L M-R) is used for offset elimination. Different parts of the complete scheme, as noted below, were considered, developed, and tested. Reviews are given of various state models, the weighted least-squares methodology, and iterative search algorithms for batch optimization with respect to formulations, terminology, features, and attributes. Several sequential (coefficient) parameter estimation methods are tested and evaluated. These include ordinary recursive least-squares (RLS) and those based upon a steepest descent search, an orthogonal directions search, a conjugate directional search, Broyden's (Rank 1) search, and the Davidon-Fletcher-Powell (DFP) search method. The last three methods utilize periodic resetting to a steepest descent step. They preformed well on noise-free test data. However, on data with inherent process (and measurement) inaccuracies (or noise), they showed an undesirable parameter spiking tendency. The overall evaluations led to the selection of RLS with simultaneous noise filter design for use in the complete adaptive control scheme. A new method to adapt the structure of the adaptive controller's models is developed and tested. This adapts the structural parameters as the numbers of delay (deadtime) elements, poles, and zeroes. A new pole-placement design is developed and tested. The design is formulated and solved as a constrained optimization problem. It can provide control even when "uncontrollable" models are encountered. The actual process control algorithm employs model state-variable control with explicit C-L M-R. Procedures are developed and tested to update the state variables of these control models as the models are adapted. The complete adaptive control scheme is shown to operate successfully for a simulated test involving a switch between processes with significantly different structural and coefficient parameters
ANALISIS FAKTOR SPASIAL TERHADAP TUBERKULOSIS DI INDONESIA TAHUN 2023 MENGGUNAKAN ROBUST SPATIAL DURBIN MODEL
No full textSpatial Durbin Model (SDM) digunakan untuk menganalisis data spasial
dengan mempertimbangkan efek wilayah. Namun, salah satu permasalahan yang
sering muncul pada model ini adalah keberadaan outlier spasial yang dapat
menyebabkan estimasi parameter menjadi tidak akurat. Untuk mengatasi
permasalahan tersebut, penelitian ini menggunakan pendekatan Robust Spatial
Durbin Model (RSDM) yang bertujuan untuk menghasilkan estimasi parameter
yang lebih akurat dan tahan terhadap pengaruh outlierspasial dalam data. Data yang
digunakan yaitu persentase tuberkulosis di Indonesia tahun 2023 yang bersumber
dari Kementerian Kesehatan Republik Indonesia dan website resmi atau publikasi
Badan Pusat Statistik. Hasil penelitian menunjukkan bahwa model RSDM
merupakan model terbaik yang dapat dilihat dari nilai R-square sebesar 84,68%
yang lebih besar dan nilai RMSE yang lebih kecil sebesar 8,0460. Faktor-faktor
spasial yang memengaruhi penyebaran TBC secara signifikan adalah variabel
persentase urban, variabel persentase sanitasi layak, dan variabel lag spasial
persentase sanitasi layak.
