In this paper, a new cooling system using a nacelle duct is proposed for the mechanical room in the household refrigerator. The conventional mechanical room consists of a condenser, a compressor and an axial fan. The axial fan is mainly responsible for cooling the condenser and the compressor. The new cooling system is developed by replacing the axial fan with the nacelle duct including the sma...

In this article, we report on two experiments that aimed to shed light on the memorability effect that derives from varying the uniqueness of contextual cues presented at encoding and retrieval. We sought to understand the locus of the recognition advantage for studying and testing words with nominally irrelevant features that are rarely shared with other words ("low-fan" features) as compared ...

As commonly used forced convection air cooling devices in electronics, cooling fans are crucial for guaranteeing the reliability of electronic systems. In a cooling fan assembly, fan bearing failure is a major failure mode that causes excessive vibration, noise, reduction in rotation speed, locked rotor, failure to start, and other problems; therefore, it is necessary to conduct research on the...

In this paper, effect of geometric parameters of a centrifugal fan with backwardand forward-curved blades has been investigated. Centrifugal fans are used for enhancing the heat dissipation from the IC engine surfaces. In the process, the fan consumes power generated from the engine. As a first step, an experimental setup was developed and prototypes of fans were made to carry out measurements ...

In a fan-planar drawing of a graph there is no edge that crosses two other independent edges. We study 2-layer fan-planar drawings, i.e., fan-planar drawings such that the vertices are assigned to two distinct horizontal layers and edges are straight-line segments that connect vertices of different layers. We characterize 2-layer fan-planar drawable graphs and describe a linear-time testing and...

Fuzzy adaptive network (FAN) is proposed to help decision makers in credit scores and to assign the amount of loan. By combining with neural networks to incorporate the learning ability, FAN provides an alternative approach for the imprecision and fuzziness of the credit rating system. A loan approval example is given and the performance of FAN is compared with the regression algorithm. The res...

Seventeen sites on the Amazon Fan were drilled during Leg 155. Although the oldest recovered sediment dates from isotopic Stage 8 (~0.25 Ma), our sampling concentrated on the last glacial cycle. Sites were correlated by seismic reflection profiles, paleomagnetic orientation and intensity, stable isotopes of planktonic foraminifers, and biostratigraphic methods. The Amazon Fan aggraded during lo...

Crayfish depend on sensilla, small cuticular structures occurring all over their bodies to acquire information about their outside environment. Sensilla contain sensory neurons that are either mechanoreceptive or chemoreceptive. The tail fan of crayfish houses numerous sensilla that contain mechanoreceptor neurons and their activation by animals approaching from behind elicits a tail-flip escap...

Aircraft engine noise research and development depends on the ability to study and predict the noise created by each engine component in isolation. The presence of a downstream pylon for a model fan test, however, may result in noise contamination through pylon interactions with the free stream and model exhaust airflows. Additionally, there is the problem of separating the fan and jet noise co...

Pleistocene alluvial fan surfaces of the Campo de Cartagena-Mar Menor Basin (Murcia, SE Spain) are capped by thick mature calcretes. Calcrete profiles consist mainly of six different horizons: prismatic, chalky, nodular, massive, laminar and coated-gravels. Petrographic study of the calcretes has shown the occurrence of features such as alveolar septal structures, calcified filaments, coated gr...
