Quantifying the response of vegetation cover change (VCC) to climatic variables is a gap that mandatory for conservation and rehabilitation natural landscapes ensure sustainability. Based on temperature rainfall data, Normalized Difference Vegetation Index (NDVI) dataset, district statistical we investigated spatiotemporal variations temperature, rainfall, urban land, VCC in all suburban areas ...

Stability assessment of conventional vector current control (VCC) voltage-source converters (VSCs) in weak grids has not been standardized. In this article, a small-signal model is derived to quantify the maximum active power transfer very grid across much wider range controller bandwidths than previously investigated. A novel investigation VCC-VSC bandwidth interactions between inner and outer...

The power-synchronization control (PSC) and vector current (VCC), the latter including cascaded outer loops, are, respectively, considered to be grid-forming grid-following schemes. They have significant structural differences. Despite that, it is here shown that two schemes can unified by making a series of minor modifications PSC. This results in universal controller, allowing various combina...

Subramanian defined the complexity class CC as the set of problems log-space reducible to the comparator circuit value problem. He proved that several other problems are complete for CC, including the stable marriage problem, and finding the lexicographical first maximal matching in a bipartite graph. We suggest alternative definitions of CC based on different reducibilities and introduce a two...

Results: The calculated results show that because of high system pressure for R290 and R134a, R600a is the more suitable working fluid for ORC in terms of expander size parameter, system efficiency and system pressure. In addition, R600a is also the most appropriate working fluid for VCC in terms of pressure ratio and coefficient of performance. R600 and R600a are more suitable working fluids f...

This paper introduces the methods we adopt to build our system for the evaluation event of Voice Conversion Challenge (VCC) 2016. We propose to use neural network-based approaches to convert both spectral and excitation features. First, the generatively trained deep neural network (GTDNN) is adopted for spectral envelope conversion after the spectral envelopes have been pre-processed by frequen...

PURPOSE To evaluate the strength and pattern of the relationship between visual field (VF) sensitivity and retinal nerve fiber layer (RNFL) thickness measurements by scanning laser polarimetry (SLP). METHODS Fifty-four eyes of 54 normal subjects (age, 42 +/- 15 years; VF mean deviation [MD], -0.69 +/- 1.01 dB) and 51 eyes of 51 glaucoma patients (age, 66 +/- 14 years; VF MD, -6.92 +/- 5.43 dB...

Abstract A renewable energy source, especially solar energy, is one of the best alternatives for power generation in rural areas. Organic Rankine cycle (ORC) can be powered by a low-grade suitable small-scale production This study investigates combined and cooling system using combination ORC vapor compression (VCC), where parabolic trough collector. Thermodynamic economic simulation conducted ...

El volumen sanguíneo es un factor fundamental en la funcionabilidad hemodinámica determinante de correcta homeostasis los seres vivos. La hipovolemia, así como hipervolemia son factores perjudiciales el paciente que padece. medición del índice colapsabilidad vena cava caudal (ICVCC) marcador predictor ciertos trastornos, pueden ser corregidos mediante administración intravenosa fluidos y poder ...

BACKGROUND To describe the clinical presentation of suprasellar cysts (SSCs) and surgical indications, and compare the treatment methods of endoscopic ventriculocystostomy (VC) and ventriculocystocisternotomy (VCC). METHODS We retrospectively reviewed the records of 73 consecutive patients with SSC who were treated between June 2002 and September 2009. Twenty-two patients were treated with VC...
