i-Perception, 2017 In January 2017, a large wind turbine blade was installed temporarily in a city square as a public artwork. At first sight, media photographs of the installation appeared to be fakes – the blade looks like it could not really be part of the scene.

Blade by Blade Tip Clearance Measurement [PDF]
International Journal of Rotating Machinery, 2011 This paper describes a capacitance-based tip clearance measurement system which engineers have used in the most demanding turbine test applications. The capacitance probe has survived extended use in a major European gas turbine manufacturer's high-temperature demonstrator unit, where it functioned reliably at a turbine entry temperature in excess of ...

On Blade Arrangement for Multi-Blade Rotors
Wind Engineering, 2011 This paper concerns the blades of multi-bladed water-pumping windmills when they have variable mass and centre of mass. The paper explores blade arrangement strategies that will minimize the eccentricity of the rotor centre of mass and hence any rotor-induced vibration.

Balancing and blade-shaping of a single-blade impeller [PDF]
Mechanics & Industry, 2019 Single-blade centrifugal pumps with a screw-shaped blade are widely used to pump slurry water containing solids and fibrous matters. These hydraulic machines should be frequently used, because of their suitable hydraulic and mechanical properties, in many industrial areas. There cannot be applied a conventional method to design a single-blade impeller,

Influence of blade-to-blade dissimilarity on alleviation of helicopter blade-vortex interactions
Mathematical and Computer Modelling, 2001 This paper numerically examines possible alleviation of parallel blade-vortex interaction (BVI), experienced by helicopters in low-speed descent, through the introduction of blade-to-blade dissimilarity. A four-bladed rotor with two sets of opposite blades is considered, and the radius of one set is reduced to 80% of the baseline radius.

Response of Bladed Disks With Mistuned Blade-Disk Interfaces [PDF]
Volume 6: Structures and Dynamics, Parts A and B, 2009 This paper focuses on the determination of the effects on the bladed disk forced response of small variations (mistuning) in the blade-disk interface properties as may result from blade seating. A blade-interface-disk mean model is first developed that relies on both the Craig-Bampton approach and a local modeling of the interface. Then, both model and

Religions, 2018 In their article ‘Transmedial worlds: Rethinking cyberworld design’, Klastrup and Tosca show that the core elements of a Transmedial World are: Mythos, the lore of the world, the central knowledge necessary to interpret and successfully interact with events in the world; Topos, the setting and detailed geography of the world; and Ethos, the explicit ...

Molecular Oncology, EarlyView.Proteomic and phosphoproteomic analyses were performed on lung adenocarcinoma (LUAD) tumors with EGFR, KRAS, or EML4–ALK alterations and wild‐type cases. Distinct protein expression and phosphorylation patterns were identified, especially in EGFR‐mutated tumors. Key altered pathways included vesicle transport and RNA splicing.

SUBMUCOUS BLADE SPECULUM. [PDF]
Journal of the American Medical Association, 1908 This speculum is designed to simplify, shorten and to facilitate generally submucous septal resection operations. A complete set consists of three pairs of blades of different sizes and one holder. One pair of blades is selected to suit the conditions of each individual case and fasten into the holder.
