Increasing functionality of electronic control units has enhanced our ability to control engine operation utilizing calibration static maps that provide the values of several controllable variables. State-of-the-art simulation-based calibration methods permit the development of these maps with respect to extensive steady-state and limited transient operation of particular driving cycles. Howeve...

A four-way, double-blind, prospective trial of treatment of abscesses by incision, curettage, and primary closure with and without antibiotic cover (clindamycin injection before operation or capsules after operation, or both) was conducted. There was no appreciable difference in mean healing time between the patients given both the antibiotic injection and the antibiotic capsules and those give...

The best operation strategies for open loop flat-plate solar collector systems are considered. A direct optimal control method (the TOMP algorithm) is implemented. A detailed collector model and realistic meteorological data from both cold and warm seasons are used in applications. The maximum exergetic efficiency is low (usually less than 3%), in good agreement with experimental measurements r...

INTRODUCTION Optimization of machining parameters is essential for improving expected outcome of any machining operation. CASE DESCRIPTION The aim of this work is to find out optimum values of machining parameters to achieve minimal surface roughness during milling operation of GFRP. DISCUSSION AND EVALUATION In this machining operation speed, depth of cut and feed rate are considered as pa...

background: surgical technique using small-diameter  instruments and single-incision laparoscopy are two new options for less invasive laparoscopic cholecystectomy (lc). in this study, we have compared mini-lc (mlc) with single-incision lc (silc). materials and methods: this study is a randomized clinical trial conducted on the patients diagnosed with  symptomatic cholelithiasis who underwent l...

Indonesia has many diverse natural resources that still cannot be utilized optimally such as the extraction of essential oil from Cabbage Roses flowers (Rose × centifolia). This study compares amendments, time, and composition fresh rose obtained by Solvent-Free Microwave Extraction (SFME) method to those using Hydro-Distillation (MHD) method. Optimum conditions same amount raw material in this...
