Eventually, this leads to fractures near contact surfaces, splitting of columns and capitals and thereby to a complete loss of bending stiffness or at least to its very significant reduction.
Exclusions of the overstressed elements makes model highly sensitive to input data, so we were focused on more detailed model of connection to closely test connection parameters.

However, only strain data in dividual positions on link members are obtained.
The mechanism has two degrees of freedom, one is the rotation of the crank activated by a DC motor with a variable-speed reduction unit, the other is micro motion of the crank pin in axes, which is achieved by a computer-motor driving a rolling guide screw.

Introduction The pressing need for the preservation of natural resources and reduction of carbon dioxide emission due to the rise of construction industry have fuelled the search for alternative solution to produce environment-friendly construction materials.
Although palm oil fuel ash has been identified to be a good supplementary cementing material research work and published data on deformation behaviour of concrete containing high volume palm oil fuel ash are not many.

The average channel capacity can be expressed as (14) The reason of the 1/2 factor is that we need two orthogonal channels or two time slots for transmitting the data in a dual-hop system.
They outperform the performence of the single-hop (dot line) due to the path loss reduction, and the difference become more evident as the value of m (or k) increases.

The partial safety factors adopted for the ULS and the permanent deflections are presented in Table 2, whereas a reduction factor of 0.56 was considered for temporary deflections.
Mechanical properties of PP_FV and PC_ASA samples are in accordance to mechanical ASTM & ISO characteristics of materials technical data.

The data collected was for the period October to December 2019.
The deleterious effects of carbide banding include reduced wear resistance, cracking along the carbides and reduction in fatigue resistance [1,5].

It was observed that a significant amount of temperature reduction occurred during minimum quantity lubrication as compared to dry machining at all the combinations of machining process parameters.
R2 and adjusted R2 are measures of how well the model fits the data.

Energy efficiency is an essential element in making efforts to ensure 20% reduction of primary power consumption by 2020.
AHP is a flexible method since it enables inclusion of measurable and immeasurable criteria, empirical data and subjective judgments.

It has been found that a mixed-hardening model has to be employed to fit the experimental data.
In particular, isotropic hardening produces higher welding distortion due to the increased energy required for plastic deformation of the workpiece, leading to a reduction of the distortion amplitude.
