An adaptive neuro-fuzzy inference systems (ANFIS) model was used for predicting regional average wind speed and power values in the Central Anatolian region of Turkey. In model development, longitude, latitude and altitude of wind stations and wind speed measurement height were taken as input variables, while wind speed and power values were taken as output variables for 4 different surface rou...

In this paper I analyze how debt structure and the strategic interaction between shareholders and creditors in the event of default a¤ect expected stock returns. By endogenizing shareholders’decision to default, the model generates new predictions linking …rm characteristics to expected stock returns through an intuitive economic mechanism. In particular, the model predicts that expected stock ...

Spatial and temporal variation in soil moisture plays a significant role in establishing efficient irrigation scheduling, climate change prediction, and sustainable land and water management. Passive microwave remote sensing at L-band is widely recognised as the preferred technique to measure surface soil moisture globally, with spatial resolution ranging from 40-100km. However, passive microwa...

The articulating surfaces of four different sizes of unused pyrolytic carbon proximal interphalangeal prostheses (PIP) were evaluated though measuring several topographical parameters using a white light interferometer: average roughness (Sa); root mean-square roughness (Sq); skewness (Ssk); and kurtosis (Sku). The radii of the articulating surfaces were measured using a coordinate measuring ma...

Microwave (MW) plasma was applied to the surface of polyimide (PI) films as a treatment to enhance the adhesion between copper deposition layer and PI surface for electroless plating. The influences of nitrogen MW plasma treatment on chemical composition of the PI surface were investigated by using X-Ray photoelectron spectroscopy (XPS). The wettability was also investigated by water contact an...

The scaling of root mean square (RMS) wave aberration in an isometrically growing eye is investigated, along with changes due to measurements made at different relative pupil sizes. It is found that, relative to an initial state, if an eye expands in all directions by the factor k, and the wave aberration is then measured at a relative pupil size which has changed over the pupil size used for t...

We present a model of competitive interaction among n symmetric …rms producing a homongeous good that includes both Bertrand and Cournot competition as special cases. In our model the intensity of competition is captured by a single parameter –the perceived slope of competitors’supply functions. We show that total welfare increases monotonically with the intensity of competition and the number ...

We setup a model of competitive interaction among symmetric …rms producing a homogeneous good that includes both Bertrand and Cournot competition as special cases. In our model the intensity of competition is captured by a single parameter –the perceived slope of competitors’supply functions. We show when the number of …rms is …xed, total welfare increases monotonically with the degree of compe...

Skin status of produce is important in determining fruit quality. Sensory evaluation is often used to express this characteristic. A new method, atomic force microscopy (AFM), was proposed to denote the changes of skin status. Arithmetic roughness (Ra) and root mean square roughness (Rq) of ‘Jinxiu’ yellow peach (prunus persicu L. Batsch.) were analysed by AFM. The Ra and Rq values increased wi...

We propose a generalization of the parallelogram identity in any dimension N ≥ 2, establishing the ratio of the quadratic mean of the diagonals to the quadratic mean of the faces of a parallelotope.
