Buildings are a crucial part of our daily life, on average people spends 85 % of their time performing activities inside of buildings and therefore the quality of the indoor environment is a critical factor affecting the happiness and productivity of building users.The indoor environmental quality has a strong relationship on the thermal conditions of a space which is directly affected by the amount of heat lost or gained due to the properties of the materials used, the external environmental conditions and the inner sources of heat; In consequence, efforts have to be made to maintain proper thermal conditions by means of using natural and mechanical strategies to provide heating, cooling and ventilation.
The level of comfort depends on several personal and environment factors.
The six main factors that define thermal comfort are the following: Personal Factors · Metabolic rate.
Environment Factors · Air temperature.
When these factors are known, the thermal sensation for the body as a whole can be predicted by calculating the predicted mean vote (PMV) using the following formula: where: is the Metabolic rate, .

Effect of Squeeze Pressure on Microstructure, Aging and Mechanical Properties of A357/ ZrO2 Composite M.
The compression properties have been evaluated and compared.
The age-hardening response is significantly influenced by many factors, such as foundry conditions and heat treatment variables [11].
The effects of increasing squeeze pressure (25, 50 MPa) on microstructure, soundness, aging behavior and mechanical properties were examined.
Load transfer is the major mechanism affecting the strength of the composite.

Based on the earthquake failure mechanism of high slope, this paper analyzes the impact factors on highway high slope seismic stability, and puts forward earthquake preventive measures for high slope.
As for which one plays a decisive role in two factors, depending on conditions.
Different types of slope failure, dominant factors are also different.
Surface water such as rainfall effect is, with rainfall infiltration, slope body weight increase and the mechanical properties decrease of slope potential slip surface or structure , at the same time, the pore water pressure increases between fracture surfaces , which is not conducive to slope stability.
Conclusions (1) Geological structure, rock and soil type, lithology, topography, hydrology geological condition and seismic load are main influence factors of high slope seismic stability

Mode III Stress Intensity Factors of Surface Crack in Round Bars A.E Ismail1, a, A.K Ariffin2,b, S.
This study presents a numerical investigation on the stress intensity factors (SIF), K of surface cracks in round bars that were obtained under pure torsion loadings or mode III.
Under a certain circumstance, the shaft failed could occur due to the mechanical [1], material or environmental [2] defects.
The linear elastic material properties, E = 222 GPa and n = 0.3.
Similar trends are observed for all a/b that are considered where FIII for a/D = 0.3 do not affected by the x/h along the crack front.

Mechanical activation of fly ash by high energy planetary ball mill and the effects on physical and morphology properties.
Results and Discussion Mechanical milling involves mechanical forces such as compressive force, shear or impact to affect particle size reduction of bulk materials.
The size of the powder particle depends on several factors such as milling speed, type of milling equipment, size of balls used and ball to powder weight ratio (BPR).
Mechanical activation able to enhance the properties of fly ash and allows it to be utilized in wider application.

The first challenge is to sufficiently refine the display of affect by mechanical devices to give the impression or appearance of emotional engagement.
Finally, third from left, an attempt to build a mechanical head with a high degree of realism (Hanson Robotics).
For most people emotion is defined by how it "feels", the property of qualia.
The challenge here, then, is to understand the properties of affect in a way that can be usefully modelled to eventually enhance the behaviour of physical robotic devices.
Planning systems for social, cognitive, robots will be required to select and prioritise goals, formulate plans and select actions to perform with human sensibilities as a primary selection factor.

The overall creep properties of HAZ are worse than those of the weld metal.
Among the HAZ structures, fine grained HAZ has the worst creep properties.
The chemical compositions and the mechanical properties of the base metal are listed in table 1 and table 2 respectively.
As mentioned above, although the creep properties are affected by various factors, the major factor characterizing final properties is microstructure.
Furthermore, these stress exponents can be largely affected by various factors, such as the test temperature, precipitation behavior of the microstructures, and other things.

It was found that the three coating factors affected the elastic modulus of the MoN coating on upper hooks.
In addition, mechanical, physical, and chemical properties of molybdenum nitrides are typically important for wear resistance, crack resistance, and corrosion resistance [4].
The elastic modulus (or Young’s modulus: E) is a material property which describes the elasticity or stiffness of a material.
Interaction effect plots of elastic modulus Since all sputtering factors and interactions between two factors were statistically significant at the significance level of 0.05, interactions were typically used to determine the optimal operating condition of the significant factors [8].
Since the interaction effect between the factors of operating pressure and Ar/N2 was higher than the other two interaction effects (see Table 2), the interaction effect plot between the two factors (operating pressure and Ar/N2) then was used to determine the optimal operating condition of the significant factors.
