this paper reviews the relationship between inflation rate and minimum wage in iran’s economy over the 1969-2005. according to the economic literature, there is a narrow relationship between inflation rate and minimum wage. some economists believe in increased inflation due to minimum wage. the other group of economists considers the increased inflation as a cause for increasing minimum wage. t...

I have influenced greatly from Justus von Liebig's (For more information on Liebig, see:1,2,3) Law of the Minimum which states that yield is proportional to the amount of the most limiting nutrient, whichever nutrient it may be. From this, it may be inferred that if the deficient nutrient is supplied, yields may be improved to the point that some other nutrient is needed in greater quantity tha...

This paper is concerned with extracting excitation signals from recorded plucked-string sounds from an acoustic guitar. Three pre-existing methods are reviewed: the matrix pencil inverse-filtering (MPIF) method by Laroche and Meillier (1994), the sinusoids plus noise inverse-filtering (SPNIF) method by Välimäki and Tolonen (1998), and the magnitude spectrum smoothing (MSS) method by Laurenti an...

While controversy surrounds skewness attributes of typical yield distributions, a better understanding is important for agricultural policy assessment and for crop insurance rate setting. Day (1965) conjectured that crop yield skewness declines with an increase in low levels of nitrogen use, but higher levels have no effect. In a theoretical model based on the law of the minimum (von Liebig) te...

Motion feature plays an important role in video retrieval. The current literature mostly addresses motion retrieval only by camera motion and global motion of individual video objects in a video scene. In this paper, we propose two new motion descriptors that capture the local motion of the video object within its bounding box. The proposed descriptors are rotation and scale invariant and based...

We define pseudocompact topological spaces and prove that every compact space is pseudocompact. We also solve an exercise from [16] p.225 that the for a topological space X the following are equivalent: • Every continuous real map from X is bounded (i.e. X is pseudocompact). • Every continuous real map from X attains minimum. • Every continuous real map from X attains maximum. Finally, for a co...

The original paper [EGMM07] is available at http://jgt.akpeters.com. This paper proposes a new method for fast ray/axis-aligned bounding box overlap tests. This method tests the slope of a ray against an axisaligned bounding box by projecting itself and the box onto the three planes orthogonal to the world-coordinate axes and performs the tests on them separately. The method is division-free an...
