It is by walking that the new arises. This study aims at establishing new issues in the construciton of optometric scales of pictures accordingly to their shape and content. It is a reflection (bibliographic-analytical) based on Danta's dissertation. It is observed that the matter is the optonometric scale ready for use. The shape, in turn, is what was developed until the generation of the matt...

This paper is an explication of secret sharing schemes, emphasizing combinatorial construction methods. The main problem we consider is the construction of perfect secret sharing schemes, for specified access structures, with the maximum possible information rate. In this paper, we present numerous direct constructions for secret sharing schemes, such as the Shamir threshold scheme, the Boolean...

The research presented applies the PROMODEL alongside a simplified discrete-event simulation approach (SDESA) and its software platform resulting from in-house construction research for modeling typical construction operations. The characteristics and modeling needs for construction and manufacturing systems are compared in general. A simple earth-moving operation and a real site operation inte...

conclusions accidents resulting in death, total disability, and partial disability impose a huge cost burden on society, whereas the employer will bear a relatively low cost. this is because of society’s health, treatment, and welfare systems available for treatment and rehabilitation of injured employees and their families. background occupational accidents represent one of the major problems ...
