Computing is often about decisions with yes or no answers. By analogy, amedical test(type of problem) checks if a patient's specimen (an instance of the problem) has a certain disease indicator (yes or no answer). The instance, represented in a Turing machine in digital form, is the in...
Recall, on the other hand, lets a user assess, given a specimen with a known label or identification, how likely it is that the model will make the correct prediction. Species-specific error rates were defined as 1 – precision or the false positive rate. For each model, we compared ...
Specimen description and tomography were completed with 3D noncontact surface metrology using interferometry (Bruker Contour GTK, Bruker Nano Surfaces Division, Tucson, AZ, USA) in the materials laboratory of King Saud University. Through an upright scan interferometer with a 5 Michelson amplification len...
Computer simulations at the atomistic scale play an increasing important role in understanding the structure features, and the structure–property relationships of glass and amorphous materials. In this paper, we reviewed atomistic simulation method
While public health officials do not have the labor or resources to collect adequate spatial and temporal coverage of where, when, and what types of mosquitoes are found, these officials may be hesitant to include citizen science data because they are not confident of the data. The GLOBE ...
According to three point bending test, the complete processes from the initiation and propagation of micro cracks to the macroscopic failure of the concrete specimen and mortar specimen are simulated through RFPA 2D (Rock Material Failure Process Analysis) Code. The authors conclude that the influence...
In the present paper, the deformation and fracture of the two kinds of tensile spceimen and TPB specimen made of 40Cr steel have been simulated by using the new model together with the large elastic-plastic deformation finite element method. The results give a good picture of the whole ...

For the control specimen (PS-C), the specimen failed by concrete crushing at the ultimate load of 3.98 kN and deflection of 32.8 mm. When considering the deflection limit of L/360 = 2300/360 = 6.38 mm, this occurs at a load level of 2.15 kN. The load level increases to 2.56 kN at...
