Write-unidirectional memories (WUMs) have been introduced recently. They are binary storage devices having a close relationship to write-once memories (WOMs). When updating the information stored by a WUM the encoder can write 1 's to some positions of the WUM or O's to some positions of the WUM but it is not allowed to do both at the same time. Wolf, Wyner, Ziv and Korner investigated WOMs in ...

The present study was conducted at Collage of Agricultural Engineering Sciences University Duhok (Sumel) and Zakho Research Center (Zakho), Kurdistan Region, Iraq, during the growing season 2021-2022 to investigate effect different factors includes broad bean cultivars (Aguadulce & Lunga Delle Cascine), herbicide treatments (Control, Basagran 300mL.100L-1, Gallant super 375mL.100L-1, + Hand...

Flash memory technology is becoming critical in building embedded systems applications because of its shock-resistant, power economic, and non-volatile nature. Because flash memory is a write-once and bulkerase medium, a translation layer and a garbage collection mechanism is needed to provide applications a transparent storage service. In this paper, we propose a real-time garbage collection m...

I assume that most students have encountered Turing machines before. (Students who have not may want to look at Sipser’s book [3].) A Turing machine is defined by an integer k ≥ 1, a finite set of states Q, an alphabet Γ, and a transition function δ : Q×Γk → Q×Γk−1×{L, S,R}k where: • k is the number of (infinite, one-dimensional) tapes used by the machine. In the general case we have k ≥ 3 and ...

Weed infestations and associated yield losses require effective weed control measures in soybean and sugar beet. Besides chemical weed control, mechanical weeding plays an important role in integrated weed management systems. Field experiments were conducted at three locations for soybean in 2013 and 2014 and at four locations for sugar beet in 2014 to investigate if automatic steering technolo...
