Diabetes mellitus affects 387 million people across the world according to the latest estimates of International Diabetes Foundation. Insulin is one of the major drugs required to keep the glucose level within desired limits in a diabetic patient. Insulin is generally administered to a ... En savoir plus

In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be ... En savoir plus

MEMS gyroscope technology provides cost- effective method for improving directional estimation and overall accuracy in the navigation systems. This paper presents a tuning- fork gyroscope (TFG) [1] with a perforated proof mass. The perforated proof mass used in the design enables the ... En savoir plus

In this paper we made an attempt to maximize the power output in the different piezoelectric materials in a unimorph cantilever beam configuration. In this research, a macro scale unimorph piezoelectric power generator prototypes consists of an active piezoelectric layer, stainless steel ... En savoir plus

Among optical gas sensing methods, photoacoustic (PA) spectroscopy combined with a laser source has proven to be a very robust and sensitive method for trace gas detection. COMSOL Multiphysics® software was used to calculate the frequency response of differential Helmholtz resonator ... En savoir plus

The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... En savoir plus

One of the limitations of pipelines performance and structural integrity assessment is the continuous inspection of possible leaks due to corrosion or other types of failure mechanisms. Efforts to develop new technologies started several decades ago where different inspection techniques ... En savoir plus

Enhanced operational flexibility and low levels of pollutant emissions are achieved with a sequential arrangement of premixed combustion stages in gas turbines for power generation. In the second – reheat – combustion stage, hot flue gases of approximately 1500K are enriched with fuel ... En savoir plus

In this paper, the effect of a crack to the flow-induced vibration characteristics of supported pipes is investigated based on vibration method. In order to estimate the crack location and depth in the pipe, we need to utilize the variation of the difference between the natural ... En savoir plus

Mathematical skin models play an important role in fields such as transdermal drug delivery and assessment of dermal exposure to industrial chemicals. Extensive research has been conducted on modeling skin for transdermal drug delivery; however, little effort has been made to view the ... En savoir plus
