Fabrication and characterization of multiphase bituminous materials for cold region pavements

In this study, the low temperature creep properties of multiphase bituminous materials (binder, mastic, Fine Aggregate Matrix—FAM, and mixture) were experimentally evaluated, and the impact of size effect on FAM and mixture specimen was also assessed. First, the mix design of mastic and FAM was performed based on the reference mixture Asphalt Concrete (AC) 22 TS. The mathematical adaptation to the boundary sieve method was applied to calculate FAM gradation and binder content. Next, a preparation method was proposed to produce Fine Aggregate Matrix (FAM) in a laboratory environment, and scale-up slab samples were also fabricated for FAM and mixture specimens to evaluate the size effect phenomenon. Finally, three-point bending (3 PB) creep tests were conducted on the multiphase bituminous specimens with different dimensions at -6 °C, -12 °C, and -18 °C with a modified Bending Beam Rheometer (BBR) device and a dynamic loading machine, depending on the sample size. Results indicate that the creep stiffness of the FAM was close to mixtures and much higher than the one observed in binder and mastic. The proposed fabrication approach provides a satisfactory method for preparing a representative FAM phase in the mixture, while the air voids can be easily adjusted during the slab compaction procedure. This study supports the idea of using FAM to discriminate asphalt mixtures for cold regions. The correlation between up-scaled FAM and mixture specimens should be further investigated, including different mixture types and corresponding FAM.

An Improved Mayfly Optimization Algorithm for Type-2 Multi-Objective Integrated Process Planning and Scheduling

The type-2 multi-objective integrated process planning and scheduling problem, as an NP-hard problem, is required to deal with both process planning and job shop scheduling, and to generate optimal schedules while planning optimal machining paths for the workpieces. For the type-2 multi-objective integrated process planning and scheduling problem, a mathematical model with the minimization objectives of makespan, total machine load, and critical machine load is developed. A multi-objective mayfly optimization algorithm with decomposition and adaptive neighborhood search is designed to solve this problem. The algorithm uses two forms of encoding, a transformation scheme designed to allow the two codes to switch between each other during evolution, and a hybrid population initialization strategy designed to improve the quality of the initial solution while taking into account diversity. In addition, an adaptive neighborhood search cycle based on the average distance of the Pareto optimal set to the ideal point is designed to improve the algorithm’s merit-seeking ability while maintaining the diversity of the population. The proposed encoding and decoding scheme can better transform the continuous optimization algorithm to apply to the combinatorial optimization problem. Finally, it is experimentally verified that the proposed algorithm achieves better experimental results and can effectively deal with type-2 MOIPPS.

Task scheduling and data replication in cloud with improved correlation strategy

Cloud providers frequently utilize two tightly coupled resource management strategies like task scheduling & data replication to boost the performance of the system generally, guaranteeing service level agreement (SLA) compliance, as well as protecting their own financial gain. An Improved Correlation strategy-based Task Scheduling and Data Replication in Cloud (ICTSDC) is what this work aims to give. The suggested system's primary phases are as follows: Management of replication and task scheduling. Initial job scheduling will be optimization-based and take into account goals such bottleneck value, migration cost, VM load, enhanced correlation, and replication, respectively. For this, a brand-new extended DMO algorithm called Self-adaptive Dwarf Mongoose Optimization (SADMO) is presented. In the replication management stage, the potential copies must first be identified based on the prior objective. The suggested SADMO model implements the optimization technique for replica placement throughout the replication management process. The outcomes of the ICTSDC technique are evaluated to other methods using a variety of metrics, like bottleneck value, migration cost, Virtual Machine (VM) load, improved correlation, as well as replication efficiency. A lower mean value of 0.324 is gained with the ICTSDC scheme for fitness.

CHANGES IN THE STRENGTH OF SAV-1 ALUMINUM ALLOYS IRRADIATED BY NEUTRONS

A team of authors conducted a study of the states and radiation damage of aluminum alloy SAV-1 before and after neutron irradiation with doses of 1016–1020 n/cm2. The measurements were carried out by volumetric methods (small-angle neutron scattering and neutron diffraction) in order to analyze the correlation of the structural state with the results of sample strength measurements obtained using a loading machine. The regularities depending on the fluence of fast neutrons of the strength parameters are revealed, and the regularities of the interdependence of the strength parameters are determined.

Quality Control of Cement Bags Using Pareto Diagrams and Analytical Hierarchy Process (AHP)

A cement company in Bengkulu which has been operating and producing premium quality cement since April 2015 is experiencing quality product issues, particularly regarding its cement bags. Raw material was the largest defect contributor, accounting for 65% of the total defective bags with the causing criteria were raw materials that did not meet specifications, no hole at the end of the valve, bags with poor adhesive strength, oversized bags, oversized pores of the bags, and the valve holes were too tight. Other defect contributor was related to machinery factor that contributed to 30% of the total defective bags with the causing criteria were conveyor belt sway, spout kick accuracy issue, poor guide plate accuracy, and loading machine with brake issues. Another defect contributor was related to human factor, that contributed to 5% of the total number of defects caused by human error such as lack of focus and fatigue. Pareto diagram was one of the seven tools in quality control. Pareto chart was a special type of bar chart where, each bar represented a different category or part of a problem. The sample used in this study was the number of defective cement bags (40 kg and 50 kg of cement bags) for the period of January-December 2019.

System of mutual loading of auxiliary electric machines with coverage of losses from mechanical power sources

Purpose. Increasing the level of safety and reducing the cost of rolling stock maintenance is an urgent problem for Ukrainian railways today. Existing test benches for auxiliary machines are usually built according to the scheme with direct loading of the tested electric machine and do not meet modern requirements for the quality and energy efficiency of testing. In this regard, there is a need to design energy-efficient test benches for testing auxiliary machines of electric rolling stock. Methodology. To achieve this goal, we used an analytical method of research to determine the optimal structure of the test bench. The paper considers the voltage balance diagram in the mutual load system. Separately, the calculations are presented, on the basis of which the design diagrams of the electrical and mechanical parts of the test bench are constructed, and the conditions for covering all losses in the mutual load system are determined using the design diagrams. Findings. In the course of the research, the power balance equation in the mutual load system was obtained. On the basis of the equations, a model of a mutual load system with coverage of all losses from a single source of mechanical power was built. The main advantage of the developed model is that it can be implemented both by numerical calculations using composite systems of equations and by object-oriented programming in specialized software systems. Originality. A rational scheme for testing auxiliary machines with the coverage of losses from a single source of mechanical power is proposed. The use of a single power source can significantly reduce the additional consumption of electrical energy due to the more efficient use of auxiliary equipment, in particular, a mechanical power source. Practical value. Based on the results obtained, it is possible to determine the parameters of the scheme for testing auxiliary machines at the design stage of the test bench. Implementation of the research results at auxiliary machine repair enterprises will reduce electricity consumption for post-repair testing due to the higher energy efficiency of the test scheme.

Effect of Friction Stir Welding on Short-Term Creep Response of Pure Titanium

Friction Stir Welding (FSW) is a recent joining technique that has received considerable attention. FSW causes significant variations in the material microstructure commonly associated with changes in the mechanical properties. The present study deals with the creep response of pure titanium (CP-Ti grade 2) after FSW. Dog-bone creep samples, obtained by machining, which show the longitudinal axis of each sample being perpendicular to the welding direction, were tested in constant load machines at 550 and 600 °C. The creep response of the FSW samples was analyzed and compared with that of the unwelded material. The shape of the creep curves was conventional, although the FSW samples went to rupture for strains lower than the base metal. The minimum creep rates for FSW samples were, in general, lower than for the unwelded metal tested in equivalent conditions. In addition, when the applied stress was high, deformation concentrated in the parent metal. The creep strain became more and more homogeneous along the gauge length as testing stress decreased. A constitutive model, recently developed for describing the creep response of the base metal, was then used to rationalize the observed reduction in the minimum strain rate in FSW samples.

Laboratory investigation of scale effects in bursting failure of quasi-brittle materials

Understanding the scale effect in the behavior of solid materials is important when small-scale models are used to predict the behavior of real structures. Tremendous efforts have been devoted to investigating the scale effect in the strength of quasi-brittle materials. However, limited studies have focused on the whether there is a scale effect in bursting failure, which is a typical failure pattern of quasi-brittle structures. Here, we conduct a series of unconfined compression tests on coal samples using a specialized designed loading machine to produce bursting failure in the laboratory. We use cubic coal samples with a large range of sizes from 50 to 300 mm to investigate the scale effect in bursting failure of quasi-brittle materials. We use acoustic emission technology to monitor microcreaking within the samples and a high-speed camera to capture the bursting failure process. We demonstrate that there is a strong scale effect in bursting failure of quasi-brittle materials in terms of mechanical properties including compressive strength and deformability, strain energy density, bursting severity, and precursor time. We found that ejection of localized pieces from the skin of the structure is a precursor of catastrophic bursting failure of quasi-brittle materials. We conclude that the relationship between the precursor time (T) and structure size (M) of bursting failure is logarithmic and can be described as logT = a + bM where a and b are constants. This relationship provides a guideline when models obtained from laboratory tests are used to predict strength and behavior at the intermediate (mines and rock slopes) and large scales (earthquakes).

Comparative Evaluation of Octa Shot Versus Quad Shot Palliative Radiotherapy for Advanced Head and Neck Cancer Patients

Background: Majority of Head and Neck Squamous Cell Cancer patients in India present in advanced stages. They are not candidates for multimodality treatment due to loco-regionally advanced disease and poor performance status. Hypo-fractionated regimens have been used for palliation of advanced head and neck cancers. Purpose: The purpose of this study to compare the acute and late toxicity and overall response of octa shot and quad shot radiation therapy as palliative regime in locally advanced head and neck cancers.Materials and methods: A hospital based prospective, randomized study was conducted with 50 patients of advanced Squamous cell carcinoma of head and neck, 25 patients taken in each arm. Two fractions(3.5Gy/#) per day six hours apart was given in four consecutive days (Octa shot). Two fractions (3.5Gy/#) per day six hours apart was given in two consecutive days repeated for one more cycle with a interval of two weeks (Quad shot). Acute toxicities monitored at day 15 &30 and late at 3 & 6 months after the treatment started. Results: Octa shot had slightly better loco-regional control but the difference was statistically insignificant. Octa shot had more grade 2 skin and mucosal reaction than Quad shot. Symptomatic relief, subjective regression and improved QOL were better in Octa shot than Quad shot. Conclusion: The study concludes that “octa shot” is an effective palliative radiotherapy regime with greater yet manageable toxicity in comparison to Quad shot regimen. This regime not only strikes a balance between the economic burden, treatment time, machine load but also helps in selecting patients for further dose escalation based on treatment response and symptomatic relief. However more such trials with longer follow up and larger sample size are required for stronger evidences.

Research on hybrid power load matching control method of new energy pumping machine

In order to improve the energy saving effect of new energy pumping machine, the power matching energy saving control of wind energy, electric energy and pumping machine load should be carried out when the actual wind speed is lower than the rated wind speed of the system. In this paper, according to the wind power hybrid transmission system, we study the load matching energy saving control strategy and method that takes into account the simultaneous change of wind speed and load, and propose the hybrid power load matching adaptive energy saving control strategy based on the cascade controller. In the strategy, the motor torque control method is used to eliminate the pressure deviation and realize the system pressure tracking load matching adaptive control, while keeping the motor output torque stable.

A Green Flexible Job-Shop Scheduling Model for Multiple AGVs Considering Carbon Footprint

Green and low carbon automated production has become a research hotspot. In this paper, the AGV transport resource constraint, machine layout and job setup time have been integrated into the background of a flexible job shop. From a whole life-cycle perspective, the AGV allocation strategy has been formulated by simulating multiple scenarios within the production system. Aimed at makespan, carbon footprint, and machine load, a green low-carbon flexible job shop scheduling model with multiple transport equipment (GFJSP-MT) has been constructed. To address this problem, a relevant case dataset was formed, and a heuristic strategy NSGA-II using a real number encoded embedded cycle to replace repeated individuals was proposed. Through longitudinal and horizontal comparisons, the effectiveness of the AGV allocation strategy has been verified and the optimum number of AGVs in the case determined. Finally the quality and diversity of the Pareto frontier solutions are compared and the scheduling scheme for each sub-objective are discussed. The results show that the model and algorithm constructed in this paper can effectively achieve the optimal scheduling of green flexible shop production.

A comparison study of using polyethylene terephthalate and limestone fillers on porous asphalt mixture behaviours

Regardless of their gradations, all varieties of asphalts pavement mixtures are smooth and impermeable, which reduces the safety of cars in different weather situations. Comfort and safety on the roads during various weather conditions are directly influenced by surface layer characteristics. Porous asphalt has quick surface drainage, eliminates splashing, and improves safety. Additionally, because water drains into the asphalt mixture's pores, the desired level of friction between the tire and the pavement will be guaranteed. This necessitates the production of permeable asphalt pavement mixtures for roads and highways that can handle heavy traffic loads. The primary objective of this study is to investigate the enhancement of stability and mechanical properties in porous mixtures by substituting conventional limestone filler with Polyethylene Terephthalate Waste Plastic (PET) powder. Simultaneously, the study aims to mitigate environmental pollution by utilizing PET materials, which take decades to decompose naturally. The PET used in the study was melted at 260 0C and then powdered using 7000, 18000, and 28000 rpm grinders to obtain filler that passed sieve no. 200. The ASTM D7064-based evaluation of the mixture's optimum asphalt content takes into account essential factors, including drain down, percentage of air voids, and optionally, the results of the Cantabro abrasion test, which was calculated to be 4.75%, decreased to 4.5% when polyethylene terephthalate powder was utilized as filler in place of limestone. The optimum limestone filler percentage was 3.0% based on National Asphalt Pavement Association (NAPA) gradation employed the same procedure in the optimum asphalt content evaluation. However, the results showed that the optimum amount when using PET powder reached 3.5%.The criteria used to investigate the newly proposed asphalt pavement mixture are the Marshall method, Drain down of binder, Cantabro loss test, and permeability of porous mixture. This research reveals that adding PET as an alternative filler to limestone reduces permeability, Drain Down, and Cantabro by 22.64%, 29.27%, and 16.33% respectively while increasing the stability by more than 15.5%. It is still promising that the permeability of the mixture stays within the desirable limit for comfort and safe driving. Filler replacement was tied to performance testing and was demonstrated to raise the deformation strength in the KIM test more than twice from 1.54 MPa to 3.63 MPa by employing a specialized head and Marshall loading machine as an alternative method to the wheel tracking test for evaluating rutting in the mixture. The index of retained stability by aging the samples in water bath at 25 °C from one to four days increased from 8.66 MPa by 33.1% to reach 12.57 MPa where filler replaced, and the indirect tensile strength based on ASTM D4867raised by 29.08% from 0.578 to 0.735 MPa for conditions samples and raised from 0.681 to 0.879 MPa to raise the unconditioned samples by 12.9%. It is also worth noting that the use of PET as a waste material has significant environmental benefits.

Reliability analysis of reusable turbine rotor blisk: An application of parametric modelling method under multi-field coupling

As a critical component of reusable rocket engines (RRE), the cyclic life of the turbine rotor blisk often varies due to uncertainties such as machining errors and other factors. However, considering the difficulty of structural reconstruction and the large number of parameters related to the blade configuration, few studies have considered the blade configuration variation due to machining errors in the reliability analysis process. To investigate the influence of factors in reliability analysis, a reliability analysis framework is established by combining parametric modelling methods with finite element analysis methods under fluid-thermal-solid sequential coupling. The influence of blade lattice changes due to machining errors on the reliability of turbine rotor blisks in reusable rocket engines (RRE) is investigated. The effects of machining errors, material, and load variability on the cyclic life reliability of rotor blisks are effectively quantified. With the suggested method, a reliability analysis is conducted for an RRE turbine rotor blisk, and the effect of the machining error range on the analysis results is investigated. It is found that the tolerance level to meet the high reliability requirements is at least medium for the basic cyclic life requirements of the model. In terms of cyclic life reliability, the more influential random factors are blade axial chord, low-cycle fatigue plasticity coefficient, and low-cycle fatigue ductility coefficient, with sensitivity factors of 29.09%, 24.4% and 22.13%, respectively. This study provides an efficient and reliable modelling method for the reliability analysis of reusable turbine rotor blisks based on machining errors, investigates the influence of the range of machining errors, quantifies the ability of the random factors to influence, and provides valuable insights and recommendations for the reliability design and optimization of reusable turbine blisks.

Static and dynamic compression load tests of conically connected, screw fixed dental abutment

The basis of the long-term success of dental implants is the mechanical stability of the implant and the superstructure anchored in it. In order to investigate the mechanical behaviour of the conical connection in implant-abutment units, static and dynamic load tests were performed with different conical angles and various Grade 4-5 titanium implant materials. The assembled units were mounted in self-developed loading machine and in an Instron ElectroPuls E3000 fatigue machine. For static loading, the samples were loaded with a force from 0 N to 500 N in steps of 100 N. For dynamic loading, the samples were loaded for 30,000 cycles with a force of 250 ± 150 N. In case of static testing, the compression caused by the load was measured in both horizontal and vertical directions, while in the case of dynamic fatigue, only horizontal deformation was defined. In both cases, the drive-out (reverse) torque values of the fixing screws were determined after loading. No significant differences were found between the tested materials in the reverse torque after the static load, however, significant differences were shown with regards to the alterations in cone angle (p < 0.001). After dynamic loading, significant differences (p < 0.001) were also observed between the reverse torques of the fixing screw in different angles. The static and dynamic test results showed the same tendency: under the same load conditions, the conical angle value of the implant-abutment connection revealed significant differences in the loosening of the fixing screw. In summary, it is recommended to use higher conical angle connection to avoid larger deformations in lengths and diameters of the implant at the connection and essential torque reduction of the fixing screw. Our results may contribute to the understanding of the long-term success of dental implants.

Experimental and numerical characterization of EPS using elastoplastic response in ABAQUS

Expanded polystyrene (EPS) is an attractive research area in the field of construction engineering. Its ultra-lightweight properties, high compressibility, and environmental-friendly characteristics make it ideal for the use as a compressible backfilling material for embankments, a filling material behind retaining walls and many other applications. Consequently, the compressive strength is one of the important properties for engineers. To this end, this paper aims to create a simplified elastoplastic model for the uniaxial unconfined compressive behavior of EPS. The developed model can predict the plastic stress–strain behavior of EPS using only its elastic modulus. A mathematical curve fitting model was developed by testing several 50 × 50 × 50 mm cube specimens under the test setup of a 50 kN uniaxial loading machine. Then, the proposed model was validated through the elastoplastic behavior in ABAQUS, by creating a finite element model for the described test setup. It was found that the proposed experimental test setup resulted in reasonable stress–strain behavior for EPS, similar to that indicated in the literature. Also, the presented mathematical model can accurately predict the stress–strain behavior of EPS, which was validated using the elastoplastic response in ABAQUS.

Evaluation of prosthetic screw loosening in all-on-four implant-supported restorations with two different connection systems

Statement of ProblemThe OT BRIDGE connection system can be an alternative to multiunit abutments (MUA) for patients with all-on-four implant-supported restorations. However, the amount of prosthetic screw loosening of the OT BRIDGE in comparison with the MUA used in all-on-four implant restorations is unclear. PurposeThe purpose of this in vitro study was to compare the loss of removal torque in the absence of load and after dynamic cyclic loading between the 2 different connection systems: OT BRIDGE attachment and MUA used in all-on-four implant-supported restorations. Material and methodsFour dummy implants (Neobiotech Co Ltd) were inserted into an edentulous mandibular model according to the all-on-four concept. Sixteen screw-retained restorations were digitally fabricated and assigned to 2 groups: the OT BRIDGE group received 8 restorations connected with OT BRIDGE (Rhein 83 srl); the MUA group received 8 restorations connected with MUA (Neobiotech Co Ltd). Restorations were tightened to the abutments according to the manufacturers’ recommendations by using a digital torque gauge. The removal torque value (RTV) was measured with the same digital torque gauge. After retightening, dynamic cyclic loading was applied by using a pneumatic custom cyclic loading machine. RTV after loading was measured with the same torque gauge. From the RTVs measured, the ratios of removal torque loss (RTL) before and after loading and the difference between before and after loading were calculated. Data were analyzed by using the independent samples t test, paired samples t test, and mixed model analysis of variance (α=.05). ResultsThe OT BRIDGE showed significantly higher RTL before loading ratio (%) than the MUA in anterior abutments (P=.002) and posterior abutments (P=.003), as well as significantly higher RTL after loading ratio (%) in anterior abutments (P=.02). The MUA showed significantly higher RTL difference between before and after loading ratio (%) than the OT BRIDGE in both anterior (P=.001) and posterior abutments (P<.001). In both systems, posterior abutments showed significantly higher RTL after loading ratio (%) than anterior abutments (P<.001). ConclusionsPosterior abutments showed more prosthetic screw loosening than anterior ones in both systems. The OT BRIDGE showed higher total prosthetic screw loosening than the MUA, although this was not significant in posterior abutments after loading. However, the OT BRIDGE was less affected by cyclic loading than the MUA.
