The accuracy of an approximate computation is the distance between the result that the computation produces and the corresponding fully accurate result. The reliability of the computation is the probability that it will produce an acceptably accurate result. Emerging approximate hardware platforms provide approximate operations that, in return for reduced energy consumption and/or increased per...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

Techniques for spherical osteotomy, such as rotational acetabular osteotomy, can help orthopaedic surgeons correct bony deformities and remove spherical acetabular components. Curved chisels are used during a spherical osteotomy, but they require skill and have a potential risk of damaging blood vessels or nerves. In order to perform a precise, quick and safe spherical osteotomy, we have develo...

Re®nements of high residue cropping practices are needed to provide crop producers viable systems that are both economically and environmentally sound. Several tillage treatments in combination with row-placed fertilizer were evaluated in a 3 year study on maize (Zea mays L.) on a Luvic Phaeozem in southern Wisconsin, USA. Tillage treatments included fall chisel, fall and spring in-row residue ...

The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

The depth of tillage and its uniformity are the main performance indicators chisel cultivators, as well all machines. Only when these at level demand, favorable conditions created for uniform development ripening crops throughout field their high yield. article theoretically explores problem ensuring a smooth movement suspension cultivator along with working depth. results show that given requi...

Kentucky, at his clinic which was a veritable beehive of activity almost entirely devoted to the surgery of the hand. I remember that it was located near about the Mohammad Ali Avenue, who recently passed away because that is where he was born as Casius Clay. Years before I first met Dr. Kleinert, I had served as a resident at the Grace Hospital in Detroit (1972) where they used to speak about ...
