This contribution presents a numerical analysis based on the effects of aerodynamics bump-based humpback whale fins available turbine blade edge. In this research, performance comparisons have been made dual sequestered blades. One blades was sinusoidal in shaped with Bumped Lead Edge (BLE) and other one Upright Leading (ULE). However, all are similar cross-sectional profile i.e. NACA-012. rese...

Mosquitoes (Diptera, Culicidae) inhabiting foliar tanks of Guzmania brasiliensis Ule (Bromeliaceae) in central Amazonia, Brazil. Mosquitoes in the family Culicidae develop their immature forms in different environments depending on various circumstances. This study represents the first contribution to the ecological knowledge of culicids living in the bromeliad G. brasiliensis. The objectives o...

Societal awareness of changes in the environment and climate has grown rapidly, and there is a need to engage citizens in gathering relevant scientific information to monitor environmental changes due to recognition that citizens are a potential source of critical information. The apparent colour of natural waters is one aspect of our aquatic environment that is easy to detect and an essential ...

In this communication, we present the progress of the 6.5m MMT adaptive optics system. During the last part of 2001 and the 1 part of 2002, the system has been validated in the laboratory statically and dynamically with sample frequencies of up to 550 Hz. In June 2002, an attempt has been made to make this system work on the telescope but has been hampered by mechanical failures. However, ease ...

Satellite communication systems play a vital role in providing Wide Area Network (WAN) due broader coverage but at the same time impose challenge for IP services in unidirectional Satellite link. This research evaluates RObust Header Compression (ROHC) for Unidirectional Lightweight Encapsulation (ULE) in terms of network performance and practical implementation design of a ROHC via Satellite t...

Guangzhou and Shenzhen are two core cities in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). It is increasingly important to regulate water quality urban development. The Forel–Ule Index (FUI) can be obtained by optical data an indicator. Therefore, we used Sentinel-2 calculate FUI of 41 lakes reservoirs from January December 2016–2021, analyzed their spatio-temporal variations, includin...

Microlithographic systems rely on precision alignment and a high-level of dimensional stability to achieve required performance. In critical applications, immunity to thermally induced dimensional changes is achieved by the use of low coefficient of thermal expansion (CTE) materials such as ULE® in components such as reflective optics and machine structures. ULE® has an expansion coefficient (α...

The precision thermal control (PTC) project was a multiyear effort initiated in fiscal year 2017 to mature the technology readiness level (TRL) of technologies required enable ultra-thermally stable ultraviolet/optical/infrared space telescope primary-mirror assemblies for ultra-high-contrast observations exoplanets. PTC had three objectives: (1) validate optical performance models, (2) derive ...
