Uniaxial compressive strength (UCS) is a significant parameter in mining engineering and rock engineering. The laboratory test time-consuming economically costly. Therefore, developing reliable accurate UCS prediction model through easily obtained parameters good way. In this paper, we set five input compare six hybrid models based on BP neural network swarm intelligence optimization algorithms...

For the symmetrical mixture model and test area, lattice point set is used to partition, then corresponding statistics can be constructed. In this paper, we first propose partition methods under sets obtain several sub-simplexes without common interior points. Furthermore, present a method for constructing uniform design on simplex using center points of these sub-simplexes. The designs satisfy...

The concept of diversity was successfully introduced for recommender-systems. By displaying results that are not only similar to a target problem but also diverse among themselves, recommender systems have been shown to provide more effective guidance to the user. We believe that similar benefits can be obtained in case-based planning, provided that diversityenhancement techniques can be adapte...

The aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. Four male sheep were selected to measure dry matter degradability of uninoculated (UCS) and inoculated (ICS) corn silage. Milk composition was measured for 22 Holstein cows, separ...

Sedimentary Rocks composing the Thar Lignite basin Pakistan are of clastic origin. These rocks have comparatively low uniaxial compressive strength (UCS) values, and hence recognized as ‘soft sedimentary rocks’ in this study. UCS is a fundamental property rocks, used by mine design engineers designing surface underground excavations. The purpose study to investigate relationship between with Br...

We observe that the relative performance of statistical relational models learned with different estimation methods changes as the availability of test set labels increases when learning from single networks. We reason about the cause of this phenomenon and develop an inference error characterization, which leads us to propose a mixture model that can learn the best trade-off between different ...

Abstract The needle penetration index (NPI) test is a non-destructive that applicable both in the field and laboratory, does not require any special sample preparation. This has been used for estimation of physico-mechanical properties soft rocks. In this study, influence clay content on relation between uniaxial compressive strength (UCS) NPI investigated some clay-bearing tests were carried o...

Eucalyptus plantations harbor great potential for supporting ecosystem services, but this prospect is weakened under long-term traditional silviculture regimes. To reform these regimes, we carried out a eco-silviculture experiment. However, the derived benefits and mechanisms that arise in mixed species stands regime are not fully understood. Here, evaluated tree carbon storage (TCS), understor...

Background: Urachal cysts (UCs) are secondary to incomplete obliteration of the embryonic urachal duct and may become symptomatic when infected. Treatment is primarily surgical to excise the infected cyst. Surgical approaches include a lower midline laparotomy or minimally invasive (MI) techniques. Case: We present a case of a young male with an infected UC that was treated with a single-incisi...
