Abstract
Hardness of a material is highly important in most architectural and engineering applications, especially considering its direct relationship with strength. As a result of this, methods of enhancing the hardness properties of materials, such as Al 6063 alloy, will of a great benefit to researchers, engineers, and architects. This study presents the effect of Equal Channel Angular Extrusion (ECAE) in enhancing the hardness of Al 6063 Alloys. ECAE is known to develop ultrafine-grained materials, which tend to be characterised by better hardness. Sets of samples made of Al 6063 were obtained, fabricated into the sizes of ECAE specimen, and grouped into seven parts. A part was taken as the control while the other six parts were went through a Sever Plastic Deformation (SPD) Process using the ECAE method. A part was extruded once, another twice, another 4 times, another 5 times and another 6 times. The microhardness values were obtained and reported, likewise, the calculated brinell hardness values were reported. From the results, it was concluded that ECAE increases the hardness of Al 6063 to an extent.

Velocity measurement method of moving object with a magnetic field source based on the measurement of the difference signal of two induction sensors
Authors: Yanvaryov S G , Gorbatenko N I , Grechikhin V V 
Published: December 2019

Abstract
The article describes a new method for measuring the velocity of movement of an object with a magnetic field source. A moving plasma piston in a channel of a magnetoplasma accelerator, which is essentially a moving conductor with current, is considered as an example of such an object. The method is based on the measurement of the difference signal of two induction sensors. The advantage of the method is the presence of a linear dependence between the primary measuring signal (difference signal) and the final informative parameter (the value of the velocity of movement of the conductor with current). The task of simplifying the velocity measurement is solved at the expense of this advantage.

Published: December 2019

Abstract
Here are presented the synthesis of paper-making machine electric drives control systems. Quality indicators of paper and cardboard are directly related to the accuracy characteristics of the electric drives of both machine wires in conditions of unpredictable changes in loads on their shafts. It is shown that to solve the problem of stabilization of wires velocities and their ratio it is advisable to implement the principle of servo control. It is proposed to use the lower wire speed stabilization subsystem as the leading one, and the upper wire speed servo subsystem with the stabilization of the zero deviation of the integral from difference of electric drives speed. Presents the results of a synthesis and analysis of two-dimensional servo system finite electric drives control in conception of the modern vector-matrix control theory. A discrete-continuous mathematical model of the electromechanical system is obtained. To ensure the quality of speed control, discrete finite state regulators are used. As a result of the synthesis, expressions for the implementation of a discrete control device are obtained. In simulation, the reactions of the drives to the increment of the speed and to the increments of the loads on the drive shafts are obtained. The simulation results showed the effectiveness of the proposed principles of electric drive control. The electromechanical system demonstrates the properties of astatic control and reduces the deviation of velocities in steady-state modes to zero. The solution to the problem of reducing the mutual influence of electric actuators for the stabilization of the velocities of the machine wire and maintaining them in the specified ratios will reduce to a minimum the displacement of the paper layers formed on both machine wires. The practical application of the proposed electric drive control system in production contributes to improving the quality of products manufactured on a paper machine.
A review of community co-benefits of the clean development mechanism (CDM)
Authors: Hultman Nate , Lou Jiehong , Hutton Stephen 
Published: December 2019

Abstract
The Clean Development Mechanism (CDM) has been the major international offset mechanism within the broader world of carbon finance. It was designed with two goals in mind: to lead to significant emission reductions that will help reduce the cost of climate mitigation in countries with commitments as well as contribute to sustainable development in the host countries. However, there has been significant discussion about the degree to which these projects fulfilled their dual mission of emissions reductions and sustainable development, particularly with respect to fostering local community co-benefits as part of broader sustainable development outcomes. In this paper, we review literature on the co-benefits delivered by the CDM at the local or community level, based on a group of 84 peer-reviewed articles and other reports. While perspectives on co-benefits are diverse, most sources argue or acknowledge that even with more recent procedural improvements, the CDM has not consistently delivered significant co-benefits to local communities. It appears likely that the situation has improved somewhat in recent years as CDM procedures have been refined, and there may be more opportunities for enhancing procedures to favor such benefits. There is overall variability in delivering co-benefits depending on the technology type, design features and the country context.
The role of cement service-life on the efficient use of resources
Authors: Miller Sabbie A 
Published: December 2019

Abstract
The high demand for cement-based materials to support building and infrastructure systems is of growing concern as the production of cement leads to significant greenhouse gas (GHG) emissions and notable resource demand. While improved efficiency of cement use has been proposed as a means to mitigate these burdens, the effects of increasing longevity of cement in-use remains a poorly studied area. This work quantitatively explores the implications of using cement for a longer in-use residence times. Specifically, this work uses dynamic material flow analysis models to quantify the in-use stock of cement in the United States from 1900 to 2015. With these models, the implications of increasing or decreasing mean longevity of in-use cement on required cement production, demand for batching water, aggregates, and energy for cement-based materials, and GHG emissions are quantified. This work shows that a 50% increase in cement longevity could have led to a 14% reduction in material resource demand and GHG emissions from concrete production in the United States, equivalent to 0.28 to 0.83 Gt of batching water, 2.9 to 7.6 Gt of aggregates, 1E + 06 to 2.3E + 06 TJ of energy, and 0.4 to 0.7 Gt of CO2-eq emissions. This percent reduction exceeds goals for reducing GHG emissions through alternative energy resources, suggesting improving durability and longevity of in-use cement stock could be a critical means to mitigating environmental impacts.

Authors: Mansyur  
Published: December 2019

Abstract
Indonesia is one of the countries that have a high earthquake intensity. Therefore, in building structure planning, there needs to be a more in-depth study of the analysis and planning of earthquake-resistant structures. The study aimed to find out the results of the building analysis reviewed in 4 Indonesian cities based on SNI 03-1726-2012 with computer programs. This research is computer-based research, with Microsoft Excel application for wall density index analysis on 1-story and 2-story buildings, and SAP2000 v.20 application on 4-story buildings for static analysis of equivalent lateral forces. In reviewing the building with analysis of wall density index, it was very influential on the magnitude of the spectral acceleration value of the earthquake. The greater of the spectral acceleration value of the earthquake in the city being reviewed, the smaller the value of the seismic capacity control of the building, which affects the level of building safety. In a building review with an equivalent static lateral force analysis, base shear and displacement values were very influential on the magnitude of the earthquake intensity if used as a comparison with other cities. In reviewing buildings with dynamic analysis of spectrum response range, base shear and displacement values were not very influential on the magnitude of the earthquake intensity if used as a comparison with other cities due to the greater burden than the earthquake load.
