The Effect of Spark Plug Position on Spark Ignition Combustion Dr. M.R. MODARRES RAZAVI‚ Ferdowsi University of Mashhad‚ Faculty of Engineering. P.O. Box 91775-1111‚ Mashhad‚ IRAN. m-razavi@ferdowsi.um.ac.ir SUMMARY The way in which position of spark plug affects combustion in spark ignition engine was studied by using the developed quasi-dimensional cycle simulation (using two-zone burning model) program. The purpose of this paper is to model the geometric interaction between the propagating

SUBJECT: ANTENNAS AND WAVE PROPAGATION 1. Define an antenna. Antenna is a transition device or a transducer between a guided wave and a free space wave or vice versa. Antenna is also said to be an impedance transforming device. 2. What is meant by radiation pattern? Radiation pattern is the relative distribution of radiated power as a function of distance in space .It is a graph which shows the variation in actual field strength of the EM wave at all points which are at equal distance from the

Karosas ENG 113 Academic Writing 6 March 2013 Homosexual Propagation in Ukraine Ukraine is a post-Soviet country; therefore‚ many Soviet-style values and beliefs still exist in Ukrainians’ minds. Ukraine still shows negative about promotion of gays as it was in Soviet Union. In 2012‚ Ukraine faced the problem of homosexuality propaganda. Because homosexual couples became very visible‚ the issue of how to relate to homosexuals propagation became urgent in the society. This issue has influenced

Asexual Propagation Lab Report Chance Bufe PSS 1411-512 Vikram Baliga April 4‚ 2012 I. Introduction- Asexual Propagation is the process of using plant materials such as the stems‚ leaves‚ and roots to multiply the number of plants. These plants eventually grow to be a brand new plant that is genetically identical to the parent plant it came from. In several types of plants‚ asexual propagation is the fastest means of new plant growth. Asexual propagation is also a good way to maintain

The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying
