The temperature of battery modules in electric vehicles must be controlled adequately to remain within a specified range for optimum performance. In this research work, thermal management with PCM was investigated experimentally and computationally. Li-Ion pack cooled removing heat generated during the charging discharging cycles. Computations experiments were carried out estimate transfer, sol...
Manufacturing a metal product with complex geometry usually will related to Investment Casting (IC) process as the process has the highest capability to deliver the intended objective. But producing the wax pattern for the process has already consumes half of the time of overall process. Rapid Prototyping (RP) is considered to be a solution as it capable to reduce the time in a large margin. Co...
The aim of this study was to use a detailed rheological characterization to gain new insights into the gelation behavior of natural waxes. To make a comprehensive case, six natural waxes (differing in the relative proportion of chemical components: hydrocarbons, fatty alcohols, fatty acids, and wax esters) were selected as organogelators to gel high-oleic sunflower oil. Flow and dynamic rheolog...
The time dependence of the formation of lotus wax tubules after recrystallization from various chloroform-based solutions on an HOPG surface at room temperature was studied by atomic force microscopy (magnetic AC mode) taking series of consecutive images of the formation process. The growth of the tubules oriented in an upright fashion follows a sequential rodlet→ring→tubule behavior. The influ...
The MSP430FR4xx microcontrollers are primarily targeted at remote control application that are equipped with infrared modulation function and an LCD display. The infrared modulation combinatory logic works with rich peripheral resources (for example, timers, RTC, WDT, and SPI) to generate infrared waveforms for transmitting infrared signals with minimal software overhead and intelligent power c...
Wrapper feature selection methods are widely used to select relevant features. However, wrappers only use a single classifier. The downside to this approach is that each classifier will have its own biases and will therefore select very different features. In order to overcome the biases of individual classifiers, this study introduces a new data mining method called wrapper-based decision tree...
A method for systematic reactor design, described by Hillestad [1], is applied to the Fischer-Tropsch synthesis. The reactor path is sectioned into stages and design functions are optimized to maximize an objective function. Two different objective functions are considered: the yield of wax and a measure of the profitability. With the chosen kinetic model [2] and the path temperature constraine...
Feedstocks for industrial applications ranging from polymers to lubricants are largely derived from petroleum, a non-renewable resource. Vegetable oils with fatty acid structures and storage forms tailored for specific industrial uses offer renewable and potentially sustainable sources of petrochemical-type functionalities. A wide array of industrial vegetable oils can be generated through biot...
INTRODUCTION The pathological diagnosis of papillary thyroid carcinoma (PTC) is generally easy on routine sections stained with hematoxylin and eosin (H&E). However, the differentiation of the follicular variant of PTC (FVPTC) from other suspected follicular-patterned lesions of the thyroid is highly difficult. Among these, the lesions for which FVPTC cannot be excluded are classified as well-d...
OBJECTIVES/HYPOTHESIS The incidence of thyroid carcinoma is rising. Few studies have examined patient characteristics that influence survival when adjusting for treatment and tumor stage/extent. STUDY DESIGN Retrospective analysis was performed using the Surveillance Epidemiology and End Results registry data among patients diagnosed with well-differentiated thyroid (WDT) carcinoma during 198...
