D Whysong and I have been carrying out a mid-IR survey of 3C radio galaxies to see which have IR-excesses, interpretable as hidden Type-1 AGN. Mostly due to relentless bad weather, we have a modest collections of observations so far. However, we can say with confidence that some radio galaxies are true kinetic, nonthermal emitters, with negligible energetic contribution from a visible or hidden...

An r-graph is an r-regular graph where every odd set of vertices is connected by at least r edges to the rest of the graph. Seymour conjectured that any r-graph is r + 1edge-colorable, and also that any r-graph contains 2r perfect matchings such that each edge belongs to two of them. We show that the minimum counter-example to either of these conjectures is a brick. Furthermore we disprove a va...

The effect of brickworks emissions on heavy metal content of soil and plants around the brick kiln chimneys was studied in the year 2006. Two brick kilns (A and B) about 600 m away from Ring Road at SufaidDheri on southerrn side of Peshawar, Pakistan were selected for this study. The two bricks kilns were North-South to each other with 300 m distance in between, such that South direction from b...

the mode of heat and mass transfer during baking of bakery products is an important factor determining the quality of the final product. the heating rate could alter the starch properties during gelatinization and affect the quality of products after baking and during aging. sangak is a kind of iranian flat bread baked on the hot pebble gravels. the aim of this study was to evaluate the impacts...

This paper presents quality Clay-Brick selection process based on intuitionistic fuzzy multi criteria group decision making through grey relational analysis. Brick plays an important role in construction field. Intuitionistic fuzzy weighted averaging operator is used to aggregate individual opinions of decision makers into a group opinion. Six criteria are considered for selection process and t...

in order to investigate the structural behaviour of persian brick masonry domes, three types of semi-circular, (drop, ordinary and raised) four-centred and (drop, ordinary and raised) pointed domes have been studied. the three-dimensional non-linear finite element method using the ansys code has been used for analysis. domes with different thicknesses and spans have been subjected to monotonic ...

This paper presents the modular robotic system SafeBot to air autonomous nuclear security applications. This research serves many Department of Energy applications for inspection and surveillance in hazardous areas. Currently four kinds of sensors are available through the SafeBot robotics system: laser ranger sensor brick, thermal sensor brick, visual sensor brick and gamma and neutron sensor ...
