monitoring the effective parameters of drying crops is necessary to evaluate and determine system performance under real conditions. hence, a monitoring system was constructed to determine the performance of a vegetation forced-convection solar dryer. digital temperature sensors were set up in the air inlet and outlet of the collector and the air outlet of the drying chamber. a program was writ...

with the wind permanent flow in the cities, obtaining the minimal pollution in the environment is accessible. different policies have been considered for optimization of cities such as attachment and or reduction of building parts like air-traps, ceiling forms and so on. due to population growth in cities and the increasing need for resettlement these people in the cities, inevitably, to the hi...

We describe a correspondence between GLn-invariant tensors and graphs. We then show how this correspondence accommodates various types of symmetries and orientations.

One mid-sized public flagship institution in the Mountain West was forced to abandon a brand-new marquee orientation and transition program, which had contributed first increase first-time student retention numbers decade. As educators around world were faced with similar challenges, three main concerns arose for this school: cancellation of all in-person instruction events indefinitely March 2...

This paper presents a trajectory tracking scheme for class of underactuated non-minimum phase marine vessels. Through proper coordinates transformations, the vessels model can be transformed into two-input-two-output strict-feedback form which general backstepping method applicable to solve control problem. To avoid possible singularity problem in recursive design, an AMO (asymptotic modificati...
