Prediction behavior of high frequency modulated by a 16 lengths Golay code undergoing honey attenuation
Optical microscopic analysis of honey is time consuming due to the period needed to prepare samples. Time reduction could be achieved with ultrasound microscopy. This paper investigates the behavior of 125 MHz signal modulated by 16-bits Golay code spread out through a honey sample containing pollen. A bipolar phase shift keying (BPSK) modulation of 125 MHz frequency by 16-bits Golay code was implemented in...

Modeling and experimental validation of drying processus of the microalgue Spirulina with consideration deformation and flow mass
The profiles of the material transfer properties in porous products such as Spirulina platensis during drying which characterize their behavior are often determined from different experimental points by destruction of the samples. However, for a long drying time, it’s impossible to slice or cut the sample correctly because of its mechanical strength and friability. It influences the evaluation of product in...

Effect of variation of different additives on some selected properties of silica sand mould for aluminium castings
The quality of castings in a green sand mould is influenced significantly by its properties, such as green compressive strength, shear strength, shatter index, compatibility, moisture content, permeability and others which depend on input parameters. Usually, the aforementioned properties of a particular casting differ due to variation in composition of the moulding sand mixtures, sand grain shape and size, bonding...

Tractor fuel consumption dependence on speed and height of ridging on a sandy loam soil
The effect of tractor forward travel speed and ridge height on the amount of fuel consumed by a tractor during ridging operation on a sandy loam soil in a humid tropical environment was investigated. The investigation was the Agricultural Development Programme farm at Rumuodumanya, Rivers State, Nigeria. The experimental plot of 160 by 32.5 m, totaling 5,200 m2, was divided into three major blocks; and further...
