Abstract:

Many minimalist houses use reinforced concrete slabs as a roof which is no cover. One phenomenon that is happening now is the emergence of acid rain due to air pollution. Concrete is very vulnerable to damage due to acid. Therefore, this study aims to use organic pozzolan into reinforced concrete slab roofs to increase resistance to acid rain. This study is experimental research in a laboratory. The slab used has three types of thickness of 10 cm, 12 cm, and 15 cm. The organic pozzolan used is rice husk ash which is used 5% by weight of the cement used in the mixture. Acid rain simulation in a laboratory is , by immersed in an acidic solution with a pH of 3. Flexural testing was conducted on the slabs that have been soaked for 28 days, 90 days, and 120 days........

Abstract:

The literature specialized in thermal comfort studies has shown that the study of this phenomenon from the predictive approach underestimates the adaptability that the study subjects may present to the thermal environment conditions, which is why it offers a reduced comfort range that this obtained with the study of this phenomenon from the adaptive approach; however, there is no reference regarding the approximation of the neutral temperature obtained with both study approaches.Thispaper shows the results obtained using the methodology of the predictive approach. The population sample isthe student communityof an Institute Advanced Studies located in Pachuca city, Hidalgo, whose bioclimate is semicold-dry. Experimental tests were conducted in a controlled environment chamber locatedin Autonomous Metropolitan University, during May 2013 to January 2014 period.........

Abstract:

For decades and centuries welding is considered one of the most used process in many industries, it used to join metals by exposing them to extreme heat to create welding form. There are several type and form for welding, and it can be utilized like electrical, gas and laser beam welding. also, several welding methods were created and developed like: shielded arc welding, semi-automatic and automatic methods like electron slag welding and gas metal arc welding, beam of electron welding and laser beam welding, and now in the modern era, robot welding becomes the most welding used in factories. until this day, welding methods continue to grow and develop, and got great attention of understanding for welding properties and quality. although welding has many benefits. Welding is considered dangerous and hazardous. And precautions are highly recommended to avoid burns, poison gas fumes and ultra violet waves..

Abstract:

Metal Injection Molding (MIM) is a process of powder metallurgy, similar to the plastic injection process. This process is ideal for obtaining parts of complex geometry, difficult to machinability, small batches with finishing and final dimensions, or not. The MPI, part generation process, has several steps that must be carefully followed to avoid errors that compromise product quality. The objective of this work was to produce parts with different polymers in a binder, High-Density Polyethylene (HDPE), and Thermoplastic Rubber (TPR) and after comparing them. Results obtained in this research showed that the parts injected with HDPE showed no defects after injection. The parts injected with Thermoplastic Rubber offered, according to the obtained results, an excellent mechanical resistance when compared to those that used HDPE.

Abstract:

We estimate the Bitcoin volatility usingthe realized stochastic volatility model. The model parameters are determined by Bayesian inference usingthe Markov chain Monte Carlo method. We apply the hybrid Monte Carlo method for the volatility update process, which is the most time-consuming part. We investigate several integrators in the hybrid Monte Carlo method and find that the 2nd order minimum norm integrator outperforms the others. The parameterphiof the model is found to be close to one, which indicates that the Bitcoin volatility ispersistent. We test the accuracy of the estimated volatilities by using standardized returns. The distribution of the standardized returns is found to be close to the standard normal distributions, which indicates that the volatility is estimated accurately by the realized stochastic volatility model..

Abstract:

Linear analysis is used in determining the forces and moments that occur in a structure due to external loads commonly. However, linear analysis (first-order) has not been able to accommodate the forces and moments that occur in the analyzed structure, such as in column members. In this case, the effects and moments that occur in the column will be enlarged due to lateral deformation. According to American Concrete Institute (ACI) regulations, can be approximated by usingmoment magnifier method, which is multiplying by a factor δ. The moment enlargement method can be used if the column slenderness (kl / r) between(22≤ kl⁄r≤100). This numerical study uses column slenderness between this value so that linear analysis (first-order) is not possible to be applied because there isa moment magnification factor with the moment magnifier methodshould be considered during analysis.The result shows thatanalysis of column slenderness effect the second-order analysis conducted on buildings with variations....
