Review ArticleOpen accessIn the abstractEchocardiography in Infective Endocarditis: An Update on its Usefulness: How, When, How Much and Where?Josep Maria Frigola, Sergio Moral, Pau Vilardell, Ramon BrugadaEchocardiography is the main imaging technique in the diagnosis of Infective Endocarditis (IE). In 85-90% of cases this diagnosis is based on some echocardiographic criteria. Transthoracic echocardiography is an inexpensive test, quickly accessible without side effects, which has become the initial imaging technique of choice in the diagnosis of IE, as well as in the assessment of complications and follow-up. … …American Journal of Infectious Diseases, Vol. 17, Issue 2 · 27 May 2021 · 7,636 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Practical Design of Anti-Theft Car Protection System Based on MicrocontrollerMohammed Abuzalata, Muntaser Momani, Sayel Fayyad, Suleiman Abu-EinProblem statement: This study presents a new design for an anti-theft protection System as an inexpensive solution to protect cars from theft and from non-authorized users by using microcontroller-based system. Approach: Three stages of protection to strengthen the security of the car: Firstly, when the user access the car by the car key and entered the wrong password, the power … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 5 Mar 2012 · 8,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Fuzzy Controller for Water Level in Stream Boiler TankSurachai PanichProblem statement: The process control of steam boiler is very popular used in the industrial. The temperature of the water is transferred directly by electrical heater. The pressure will increase based on the changing of the temperature. The purpose of the control is to change the opening set point for the valve when the temperature and pressure in the tank … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 8,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiesel Engine Convert to Port Injection CNG Engine Using Gaseous Injector Nozzle Multi Holes Geometries Improvement: A ReviewSemin, Abdul Rahim Ismail, Rosli Abu BakarThe objective of this study was to review the previous research in the development of gaseous fuel injector for port injection CNG engine converted from diesel engine. Problem statement: The regular development of internal combustion engines change direction to answer the two most important problems determining the development trends of engines technology and in particular, their combustion systems. They were … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Apr 2009 · 8,640 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Flow Structures of Circular Pulsating Air JetRozli Zulkifli, Kamaruzzaman Sopian, Shahrir Abdullah, Mohd Sobri TakriffProblem Statement: Applications of impingement jets in industry for heating and cooling purposes requires a high convective heat transfer coefficient. Numerous studies have been conducted to improve the convective heat transfer coefficient for a steady impinging jet. A pulsating jet has a very high potential in replacing steady jet after it been found able to increase the heat transfer coefficients … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Analysis of Six Pharmaceuticals using Online Solid Phase Extraction Liquid ChromatographySiti Norbayu Mohd Subari, Rozita Osman, Norashikin SaimIn this study, three parameters (sample volume, cleanup and elution step) in large volume injection online Solid Phase Extraction Liquid Chromatography with diode array detection (SPE-LC) were optimized for the determination of six pharmaceuticals in wastewater samples. Preconcentration and separation were carried out using 2 columns, Dionex Ion Pac AG14A and Acclaim Polar Advantage II. Response Surface Methodology (RSM) was … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 31 Mar 2017 · 7,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,858 accessesView PDFCite

Research ArticleOpen accessIn the abstractAutomatic Detection of the End-Diastolic and End-Systolic from 4D Echocardiographic ImagesAnas A. Abboud, Rahmita Wirza Rahmat, Suhaini Bin Kadiman et al.Accurate detection of the End-Diastolic (ED) and End-Systolic (ES) frames of a cardiac cycle are significant factors that may affect the accuracy of abnormality assessment of a ventricle. This process is a routine step of the ventricle assessment procedure as most of the time in clinical reports many parameters are measured in these two frames to help in diagnosing and … …Journal of Computer Science, Vol. 11, Issue 1 · 25 Aug 2014 · 8,506 accessesView PDFCite
