To use fewer components to construct a multilevel inverter (MLI) with more levels and high quality of the output voltage, hybrid MLI is developed by combining double-mode switched-capacitor (SC) unit T-type fed flying capacitors (FCs). The SC used boost amplitude voltage twice dc input while responsible for increasing number levels. A total ten transistors, four capacitors, two diodes are gener...

OBJECTIVE Previous studies have reported similar results of shoulder MRI versus arthroscopy for high-field-strength (1.5-T) and low-field-strength (0.2-T) units. We report our experience with the accuracy of high- versus low-field-strength units versus arthroscopy for detection of supraspinatus tendon tears and labral tears in the same patients. SUBJECTS AND METHODS. Three musculoskeletal radio...

A new artificial shelter unit was compared with segments of bamboo cane lined with pleated filter paper for detecting peridomestic Triatoma infestans Klug at Amamá and nearby rural villages in northwestern Argentina. The new shelter unit consisted of a black plastic, wide-mouthed jar with a screw cap on the top, and a removable central structure made of pleated corrugated paper. In devices expo...

The Horvitz-Thompson estimator is a general estimator for a population total, which can be used for any probability sampling plan. This includes both sampling with and without replacement. • Let π i be the probability that the i th unit of the population is included in the sample (inclusion probability). • On each unit i, we measure a response y i , and typically seek to estimate: τ = N i=1 y i...

The Piedade Granite (approximately 600 Ma) was emplaced shortly after the main phase of granite magmatism in the Agudos Grandes batholith, Apiaí-Guaxupé Terrane, SE Brazil. Its main units are: mafic mineral-rich porphyritic granites forming the border (peraluminous muscovite-biotite granodiorite-monzogranite MBmg unit) and core (metaluminous titanite-bearing biotite monzogranite BmgT unit) and ...

The ring Z has many analogies with the ring Fp[T ], where Fp is a field of prime size p. For example, for nonzero m ∈ Z and nonzero M ∈ Fp[T ], the residue rings Z/(m) and Fp[T ]/M are both finite. The unit groups Z × = {±1} and Fp[T ]× = Fp are both finite. Every nonzero integer can be made positive after multiplication by a suitable unit, and every nonzero polynomial in Fp[T ] can be made mon...

Abstract Zarrabi proved in 1993 that if the spectrum of a contraction T on Banach space is countable subset unit circle

We apply bootstrap methodology to unit root tests for dependent panels with N cross-sectional units and T time series observations. More speci cally, we let each panel be driven by a general linear process which may be di erent across crosssectional units, and approximate it by a nite order autoregressive integrated process of order increasing with T . As we allow the dependency among the innov...

The contribution of this paper is three-fold. Firstly, a characterisation theorem of the sub-hypotheses comprising the seasonal unit root hypothesis is presented which provides a precise formulation of the alternative hypotheses against which regression-based seasonal unit root tests test. Secondly, it proposes regressionbased tests for the seasonal unit root hypothesis which allow a general se...
