Graphical description techniques are especially useful in the early development phases like requirements engineering. There, often a trail-and-error approach is applied to develop a first system specification. However, even there a precise meaning of those description techniques is necessary, especially in trial-anderror phases based on a service-oriented description of the requirements to chec...

The turning process is one of the machining processes for producing machine components. Where lathe included in that uses a chisel. quality cut surface depends on cutting conditions, example low with large feed and depth will result rough so on. This study aims to determine what effect angle length use chisel, where chisel used an HSS In this using experimental research methods aim knowing time...

in order to determine the effect of different tillage methods on grain yield and yield components of two wheat cultivars an experiment was conducted in sanandaj in during 2005 and 2006-2007. experiment was carried out in a split plot design based on rcbd with four replications. the three methods of tillage, including moldboard plow, chisel plow and no tillage were arranged as main plots, and tw...

the aim of this research was to investigate performance of two combined plows compared to conventional plow. the experiments were conducted in a loamy soil texture with moisture content of 16-18% in karaj region of iran. combination of moldboard+chisel plow and disk plow+chisel plow were compared with conventional moldboard plow as three treatments. data was statistically analyzed using rcbd in...

With the current ever-increasing demand for performance, hardware developers find themselves turning ever-more towards construction of application-specific accelerators to achieve higher performance and lower energy consumption. In order meet ever-shortening time constraints, both development verification tools need be improved. Chisel, as a language, tackles this problem by speeding up digital...

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 ...
