noise reduction and efficiency of gears in diesel engine Thesis: In most machines‚ the major requirements for gear transmission are low sound excitation character‚ a high-level load carrying capability and generally high efficiency‚ which is more vital with increased environmental awareness. This paper discusses and analyzes two main elements gear system efficiency improvement and sound excitation. The main reason in noise reduction at gear system is given. Recommendations for reduction in sound

ABSTRACT The experiment deals with determining the standard reduction potentials of different electrochemical half-cells through pairing it with Cu2+(0.1 M)|Cu half-cell and then comparing it with the theoretical value. Galvanic or voltaic cells contain the anodic and cathodic cell reactions‚ and in order to get the value of Ecell‚ we add both half-reactions. The more positive the Ecell‚the more negative ΔG would be‚ thus‚ giving us a spontaneous reaction. After comparing the cell potentials

INTRODUCTION Wireless Integrated Network Sensors (WINS) combine sensing‚ signal processing‚ decision capability‚ and wireless networking capability in a compact‚ low power system. Compact geometry and low cost allows WINS to be embedded and distributed at a small fraction of the cost of conventional wireline sensor and actuator systems. On a local‚ wide-area scale‚ battlefield situational awareness will provide personnel health monitoring and enhance security and efficiency. Also‚ on a metropolitan

chloride an anion. The potassium end of the molecule becomes slightly positive and the other end slightly negative. Na – sodium contains metallic bonding. It has a high melting due to the bonding and has strong bonds. Each sodium atom is being touched by eight other sodium atoms and they all share electrons between the nuclei and shells. The electrons can move freely within the sodium metal and therefore can conduct electricity.
