Published: September 2020

Abstract
The sudden switchover from the fossil-fuel energy machineries to renewable energy would throw 13% of the work force into joblessness. It would take close to two decades to reintegrate existing energy players in developing countries to renewable energy option. In this research we proposed a green solution where existing energy player can be integrated into renewable energy option at no cost. The biogas motor generator was proposed so that the poorest homes could afford it. The technicalities of the biogas motor generator was discussed i.e., considering the vital role of control valve in sending 52% methane into the generator. It was observed that a valve of cross-sectional area 0.8 mm2 would withstand the anomalies of designing a biogas generator without the purifier chamber.

Abstract
An adversary can easily capture a wireless sensor network (WSN) node and extract the security information stored in the node, including keys, shared secrets and so on. Due the resources limitation, the traditional encryption and authentication protocols are impractical on WSN nodes. In this letter, we proposed a lightweight and energy-efficient anti-clone design for the WSN nodes, in which physical unclonable function (PUF) is adopted to enhance the security of the WSN nodes. The new structure aims at achieving a low cost and low energy method to prevent the node to be captured and cloned by the adversary. Unclonable WSN nodes are implemented on cypress PSOC 4, in which a configurable PUF structure is accomplished by use the universal digital block. Experimental results show that the proposed system can prevent the capture and clone attack in wireless sensor network, which is unavailable in previous WSN nodes.

A Highly Portable Solution for MWD Data Remote Transmission
Authors: Ma Chaoqun 
Published: September 2020

Abstract
The remote transmission of drilling information is the development trend of modern drilling wells. However, due to historical reasons, the early MWD in China generally did not have the remote transmission function, or did not support the standard WITS protocol remote transmission function. Because of the number of such MWDs is large, the price of MWD is expensive, and the stability of the performance, ease of maintenance of MWD, now MWD is still in large use, so it is necessary to develop MWD remote transmission functions in order to make full use of these large amounts of MWD resources. However, because there are so many different domestic MWD brand models, and their decoding software is also different, and some of the early software development did not consider the remote design, so how to find a general and simple solution, to achieve the MWD remote transmission function, in order to make full use of MWD resources, has a realistic significance.
After carefully studying the existing various MWD data characteristics, this paper designs a common WITS remote transmission solution for the data storage structure of MWD, which is based on the data storage structure of MWD, and the storage mechanism. With this solution, the innovative data from the database is read and converted to the WITS format, using the TCP/IP protocol and the Serial Port protocol to send. Because this scheme reads data directly from the database file, it avoids communication restrictions with The MWD software and has a strong portability.
Using this solution, The WITS function was developed for HL-MWD and tested in the actual drilling. The results show that the solution is stable and feasible, portability is strong, has universal reference significance for other similar MWDs, and can be developed quickly on the basis of this solution for other MWDs.

Published: September 2020

Abstract
This study aims to stabilize expansive soil with RHA by 0%, 3%, 6% and 9%. The index properties test with existing soil included lean clay (CL). The existing soil was repaired by adding stabilizing material in the form of RHA as an added material. Based on the specific gravity test, it can be concluded that the addition of RHA reduced the value of specific gravity, made the plastic limit (PL), liquid limit (LL) and plasticity index (IP) decrease, which means that it could improve the properties of the existing physical soil. Standard Proctor Compaction Test (SPCT) with unsoaked method was conducted by giving 3 different number of blows, i.e. 10, 25, and 56 blows in 3 layers. The results show that the optimum moisture content (OMC) was almost constant, while the maximum dry density (MDD) slightly increased and most were added to an additional 6% of RHA. CBR test results show that the existing soil was 0.053 and after adding RHA, increased to 130% in the addition of 6% of RHA.

Published: September 2020

Abstract
Studies on structure design optimization have been conducted extensively over the past decades because it can increase structural efficiency and maximize the engineers’ profit. One of the significant current discussions is the reliability aspect of structure design in addition to optimal design. This problem becomes more important especially in sizing and shaping optimization of truss structures. To address the problem, this paper applies Reliability-based Design Optimization (RBDO) by combining Latin Hypercube Sampling (LHS) and metaheuristic algorithms which are Particle Swarm Optimization (PSO) and Barebone PSO (BBPSO). The presence of uncertainty is modeled using LHS and the reliability constraint is added to measure the probability of structural failure. This study aims to investigate the performance of these metaheuristic algorithms in optimizing the structure design while still satisfying the reliability constraints. Two case studies, a welded beam design problem and 15-bar planar truss problem, are used in this study. The performance of these two algorithms will be compared. The obtained results indicate that BBPSO has a better performance than PSO.

Published: September 2020

Abstract
One of the most commonly used materials in civil engineering is concrete; not only is it cheap and strong, but it is also efficient and convenient. The efficiency of concrete is based on the easiness to place and to compact, which is usually known as workability. However, concrete strength and workability works in different ways; hence it is important to divide concrete into two groups: concrete with low workability and concrete with high workability, in order to achieve a more accurate prediction. Since there is a lot of variations of concrete mix designs, the relationship between each mixture is complex and, thus, requires advanced prediction methods in order to find the most accurate relationships between concrete mix proportion and its compression test result.–Recently, many studies have been conducted on applying multiple artificial intelligence (AI) methods in building different complex and challenging prediction models. Thus, this research employs ensemble machine learning methods to precisely forecast compression strength of concrete mix proportion. The accuracy of the proposed method was calculated using two performance measurements. Subsequently, the study has successfully built the prediction model that can accurately map the relationship between concrete mix proportion and compressive strength.

Abstract
Since 2014 sedimentation at the estuary of Jelitik river, Sungailiat, Bangka has continued to increase. At this estuary, the ship traffic is very busy and there is National Fisheries Port Sungailiat. When the tide is low, the river mouth closes thus disrupting ship traffic. The Bangka Belitung Provincial Government is currently planning to build a sediment control infrastructure to reduce the sedimentation rate. To plan and determine the effectiveness of the jetties requires knowledge of sedimentation patterns around Jelitik estuary. Therefore this study was conducted to determine the pattern of sedimentation (distribution and rate) at the existing and ultimate conditions. The methods are field survey, analysis of field data, and computational modeling of sediment transport. Modeling of sediment transport was done using the Sand Transport Module of MIKE 21. Two scenarios were simulated for the existing and ultimate conditions. Based on this modeling, the sedimentation rate at Jelitik estuary is found uneven. In the existing condition, a large rate of sedimentation occurs on the southern side of the Jelitik River estuary, which reaches a maximum value of 2.75 m/year, with an average of 4.44 cm/year. Whereas in the ultimate condition, the sedimentation rate decreases to 0.0377 m/year.
