Agile Approaches for Successfully Managing and Executing Projects in the Fourth Industrial Revolution

The fourth industrial revolution utilizes artificial intelligence by automating large quantities of numbers to increase the chances of project success. The Project Management Institute lists examples of project outcomes, including but not limited to the Pyramids of Giza, the Great Wall of China, the Panama Canal, and the placement of the International Space Station into Earth's orbit. This chapter highlights how the fourth industrial revolution (Industry 4.0) impacted the evolution of agile project management practices. It discusses how these could be applied in conjunction with traditional waterfall project management or as a standalone approach. Topics discussed include a definition and elements of project management, waterfall vs. agile project management, transitioning to agile methods, developments in agile project management, agile practices, and leading agile projects and project managers.
A self-consistent Hamiltonian model of the ponderomotive force and its structure preserving discretization

In the presence of an inhomogeneous oscillatory electric field, charged particles experience a net force, averaged over the oscillatory timescale, known as the ponderomotive force. We derive a one-dimensional Hamiltonian model which self-consistently couples the electromagnetic field to a plasma which experiences the ponderomotive force. We derive a family of structure preserving discretizations of the model of varying order in space and time using conforming and broken finite element exterior calculus spectral element methods. In all variants of our discretization framework, the method is found to conserve the Casimir invariants of the continuous model to machine precision and the energy to the order of the splitting method used.
Quality Considerations in Qualitative Inquiry: Expanding Our Understandings for the Broader Dissemination of Qualitative Research

The power and usefulness of qualitative research over other types of research inquiry comes from its unsurpassed ability to explain process and reveal complexity (Creswell, 2013; Maxwell, 2013). While quantitative researchers tend to be interested in numerically representing characteristics, variables, or concepts of interest (see Hjalmarson & Moskal, 2018 for quality considerations in quantitative research), qualitative researchers more often focus on people, relationships, situations, events, and processes (Maxwell, 2013). Many believe qualitative research can reveal the bigger picture often missed in quantitative research (Alasuutari, 2010; Maxwell, 2013). Given the recent recognition of qualitative research, we have begun to see an increase in this approach to inquiry, particularly in engineering education. Because our ultimate goal is to encourage engineering education researchers interested in qualitative methodologies to develop their unique “ways of being” and “ways of knowing” as qualitative researchers, we attempt to draw together flexible standards for the dissemination of engineering education’s qualitative research in this editorial.
Force Analysis of a Circular Cylinder at Ununiformed Flow in a T Pipe Junction

Experimental and numerical investigations of force analysis acted on single circular cylinder in the T pipe junction with the effect of vanes are reported in this paper. Experiments are carried on in a small wind tunnel at five different velocity ratios (R) from 0.117 to 0.614. The mean pressure data acted on the cylinder are obtained and in turn the drag and lift. Vanes are installed at the junction to change the secondary flow in the branch duct and the angle is in the range of 90° ≤ φ ≤ 130°. Numerical studies which are validated by the experimental data help understand the flow structure for the analysis. It is found that in the T shape junction without vanes, the cylinder presents different surface mean pressure distributions at the different positions in the suction duct. As the increase of the distance from the junction to the cylinder center, the surface mean pressure distributions recover to the benchmark gradually which performs in the straight duct beforehand. Four feature points including the front/rear stagnation points and the separation points and the corresponding three divisions of flow region are analyzed in detail with the auxiliary numerical simulation of flow structure. Effect of the vanes with different angle is also discussed. Finally, the drag and lift coefficients acted on the cylinder with or without vanes are performed.

Novel Topologies of Power Electronics Converter as Active Magnetic Bearing Drive

Active magnetic bearing is a core technology for high-speed rotational machines. Power electronics converter as the active magnetic bearing drive is the actuation unit and its topology highly impacts the performance of the bearing system. This paper introduces the progress of topology of active magnetic bearing drive. The initial topology of an H-bridge does not sufficiently utilize the power electronics devices. The topology with half-bridge and shared phase-leg has been proposed as the fundamental topology. In this paper, two approaches of novel magnetic bearing drive topology modification have been developed on the basis of the fundamental topology. In the first approach, central phase-leg for multiaxis magnetic bearing drive can be further shared and the power electronic devices can be globally optimized in the whole system. Further, a topology with current in the reverse direction can reduce the central phase-leg current rating and power losses. In the second approach, fault-tolerant magnetic bearing drive topology has been developed on the basis of the fundamental topology, too. It can ride-through the open-circuit fault of power electronics switch-in operation and keep levitation for the magnetic bearing. The series work of novel topologies can improve the performance of an active magnetic bearing system in application.
Soil organic carbon content and composition of 130-year crop, Soil organic carbon content and composition of 130-year crop, pasture and forest land-use managements pasture and forest land-use managements

Conversion of former agricultural land to grassland and forest ecosystems is a suggested option for mitigation of increased atmospheric CO 2 . A Sharpsburg prairie loess soil (ﬁne, smectitic, mesic Typic Argiudoll) provided treatments to study the impact of long-term land use on soil organic carbon (SOC) content and composition for a 130-year-old cropped, pasture and forest comparison. The forest and pasture land use signiﬁcantly retained more SOC, 46% and 25%, respectively, compared with cropped land use, and forest land use increased soil C content by 29% compared with the pasture. Organic C retained in the soils was a function of the soil N content ( r 5 0.98, P o 0.001) and the soil carbohydrate (CH) concentration ( r 5 0.96, P o 0.001). Statistical analyses found that soil aggregation processes increased as organic C content increased in the forest and pasture soils, but not in the cropped soil. SOC was composed of similar percentages of CHs (49%, 42% and 51%), amino acids (22%, 15% and 18%), lipids (2.3%, 2.3% and 2.9%) and unidentiﬁed C (21%, 29% and 27%), but differed for phenolic acids (PAs) (5.7%, 11.6% and 1.0%) for the pasture, forest and cropped soils, respectively. The results suggested that the majority of the surface soil C sequestered in the long-term pasture and forest soils was identiﬁed as C of plant origin through the use of CH and PA biomarkers, although the increase in amino sugar concentration of microbial origin indicates a greater increase in microbial inputs in the three subsoils. The practice of permanent pastures and afforestation of agricultural land showed long-term potential for potential mitigation of atmospheric CO 2 .
A Class of Quasi-Cuk DC/DC Converters: Steady-State Analysis and Design

Abstract In this paper, new topologies for quasi-Cuk converter are proposed. The proposed converters with different voltage and current transfer ratio and reduced voltage stress on capacitor can be employed in distributed generation (DG) systems. In this paper, steady-state analysis of two proposed quasi-Cuk converters in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) is presented. Then, besides values designing of used elements, maximum and minimum values of their current and voltage are calculated. Moreover, critical inductances between CCM and DCM for the proposed converters are calculated. Unique features of the proposed converters are different transfer ratio without employing additional elements compared to the conventional Cuk converter. Comparison of the proposed converters with conventional converter in terms of voltage transfer ratio, voltage stress on capacitor, and voltage stress on switch demonstrates advantages of the proposed converters. Finally, experimental results to verify the accuracy of the proposed converters in different operating modes are presented.
Heterarchy of Transcription Factors Driving Basal and Luminal Cell 2 in

Cell differentiation is effected by complex networks of transcription 24 factors that co-ordinate re-organisation of the chromatin landscape. 25 The hierarchies of these relationships can be difficult to dissect. 26 During in vitro differentiation of normal human uro-epithelial cells, 27 formaldehyde-assisted isolation of regulatory elements (FAIRE-seq) 28 and RNA-seq were used to identify alterations in chromatin 29 accessibility and gene expression changes following activation of the 30 nuclear receptor PPARG as a differentiation-initiating event. 31 Regions of chromatin identified by FAIRE-seq as having altered 32 accessibility during differentiation were found to be enriched with 33 sequence-specific binding motifs for transcription factors predicted 34 to be involved in driving basal and differentiated urothelial cell 35 phenotypes, including FOXA1, P63, GRHL2, CTCF and GATA3. In 36 addition, co-occurrence of GATA3 motifs was observed within sub- 37 sets of differentiation-specific peaks containing P63 or FOXA1 after induction of differentiation.
Marta (2016) Sex-specific responses of phenotypic diversity to environmental variation. Ecography, 39 (8).

23 Identifying the factors generating ecomorphological diversity within species can provide a window 24 into the nascent stages of ecological radiation. Sexual dimorphism is an obvious axis of intraspecific 25 morphological diversity that could affect how environmental variation leads to ecological divergence 26 among populations. In this paper we test for sex-specific responses in how environmental variation 27 generates phenotypic diversity within species, using the generalist lizard Gallotia galloti on Tenerife 28 (Canary Islands). We evaluate two hypotheses: the first proposes that different environments have 29 different phenotypic optima, leading to shifts in the positions of populations in morphospace between 30 environments; the second predicts that the strength of trait-filtering differs between environments, 31 predicting changes in the volume of morphospace occupied by populations in different environments. 32 We found that intraspecific morphological diversity, provided it is adaptive, arises from both shifts in 33 populations’ position in morphospace and differences in the strength of environmental filtering among 34 environments, especially at high elevations. However, effects were found only in males; 35 morphological diversity of females responded little to environmental variation. These results within 36 G. galloti suggest natural selection is not the sole source of phenotypic diversity across environments, 37 but rather that variation in the strength of, or response to, sexual selection may play an important role 38 in generating morphological diversity in environmentally diverse settings. More generally, disparities 39 in trait-environment relationships among males and females also suggest that ignoring sex differences 40 in studies of trait dispersion and clustering may produce misleading inferences. 41
A Miniature Smart City Experimental Set for Engineering Education

This paper introduces a miniature experimental set demonstrating a smart city and its components for engineering education. The model prototype simulates the real life loads and energy sources in a small lab scale, employing the ZigBee communications and power control modules for many use cases in a typical smart city. The grids become smarter with the increase of renewable energy systems’ usage, distributed energy production, and the availability of control and communication technologies on power grids. Therefore the education institutions take actions to educate the students on the state of the art smart grid components. As a part of this goal, the miniature smart city model was developed and some interactive software applications have been embedded to mimic the real smart city applications for engineering education.
Hyperbolicity in non‐metric cubical small‐cancellation

Given a non‐positively curved cube complex , we prove that the quotient of defined by a cubical presentation satisfying sufficient non‐metric cubical small‐cancellation conditions is hyperbolic provided that is hyperbolic. This generalises the fact that finitely presented classical small‐cancellation groups are hyperbolic.

Abstract The characteristics of high performing teams and their correlation with excellent task results and individual satisfaction have been studied extensively. Consequently, these characteristics have become selection criteria for new graduates, development targets and performance benchmarks for employees and entrepreneurs alike that define aspects of corporate culture. Engineering design and engineering safety and risk management instructors at a large Canadian university have been using the Comprehensive Assessment of Team Member Effectiveness (CATME) tools from Purdue University for peer evaluation and team selection for the past several years. The Individual and Team Performance Metrics Lab (ITP Metrics) has recently developed team and leadership tools including peer and team evaluation for student and industry use. CATME and ITP Metrics differ in methodology, scope, emphasis, user interface, feedback format, and cost. The selection of peer evaluation and feedback tools for student team development and evaluation should include skill development and reliable assessment of student performance in case differential grades are required. The method of data collection, the type of feedback and the contextual validity of the feedback may impact students’ development of useful team behaviours and personal strategies for working in team environments. In this contribution, outcomes from a situative study with CATME and ITP Metrics are reported and discussed based on mentoring design teams in a course where CATME and then ITP Metrics evaluations were used for sequential student cohorts in introductory and capstone design courses.
Integrative PGC-1 (cid:1) Deficiency Accelerates the Transition to Heart Failure in Pressure Overload Hypertrophy hypertrophy by preserving glucose metabolism and preventing oxidative stress.

Rationale: Pressure overload cardiac hypertrophy, a risk factor for heart failure, is associated with reduced mitochondrial fatty acid oxidation (FAO) and oxidative phosphorylation (OXPHOS) proteins that correlate in rodents with reduced PGC-1 (cid:2) expression. Objective: To determine the role of PGC-1 (cid:1) in maintaining mitochondrial energy metabolism and contractile function in pressure overload hypertrophy. Methods and Results: PGC-1 (cid:1) deficient (KO) mice and wildtype (WT) controls were subjected to transverse aortic constriction (TAC). Although LV function was modestly reduced in young KO hearts, there was no further decline with age so that LV function was similar between KO and WT when TAC was performed. WT-TAC mice developed relatively compensated LVH, despite reduced mitochondrial function and repression of OXPHOS and FAO genes. In nonstressed KO hearts, OXPHOS gene expression and palmitoyl-carnitine-supported mitochondrial function were reduced to the same extent as banded WT, but FAO gene expression was normal. Following TAC, KO mice progressed more rapidly to heart failure and developed more severe mitochondrial dysfunction, despite a similar overall pattern of repression of OXPHOS and FAO genes as WT-TAC. However, in relation to WT-TAC, PGC-1 (cid:1) deficient mice exhibited greater degrees of oxidative stress, decreased cardiac efficiency, lower rates of glucose metabolism, and repression of hexokinase II protein. Conclusions: PGC-1 (cid:1) plays an important role in maintaining baseline mitochondrial function and cardiac contractile function following pressure overload ( contribute to mitochondrial dysfunction in pressure-overload hypertrophy (POH) and heart failure, the role of PGC-1 (cid:2) was unknown. Using PGC-1 (cid:2) deficient mice, we show that PGC-1 (cid:2) regulates mitochondrial OXPHOS but not their FAO capacity, without affecting LV function. In contrast to PGC-1 (cid:1) deficiency, there is no compensatory increase in mitochondrial metabolism of glucose-derived carbon. After transverse aortic constriction (TAC), PGC-1 (cid:2) KO hearts decompensate more rapidly to heart failure as a result of an increase in oxidative stress, a decrease in cardiac efficiency, and a failure to upregulate glycolysis and glucose oxidation, despite only modest additional reductions in mitochondrial function. In control animals, TAC is initially associated with induction of PGC-1 (cid:2) that correlates with increased glucose utilization, despite mitochondrial dysfunction. These studies show for the first time that PGC-1 (cid:2) plays a critical role in maintaining antioxidant mechanisms and in activating glucose utilization in POH, both of which are believed to be important adaptations that prevent the transition from compensated POH to heart failure. Thus, modulation of PGC-1 (cid:2) may represent a novel approach for retarding the transition from compensated POH to heart failure.
Design and Experimental Validation of a Cooperative Adaptive Cruise Control System Based on Supervised Reinforcement Learning

This paper presents a supervised reinforcement learning (SRL)-based framework for longitudinal vehicle dynamics control of cooperative adaptive cruise control (CACC) system. A supervisor network trained by real driving data is incorporated into the actor-critic reinforcement learning approach. In the SRL training process, the actor and critic network are updated under the guidance of the supervisor and the gain scheduler. As a result, the training success rate is improved, and the driver characteristics can be learned by the actor to achieve a human-like CACC controller. The SRL-based control policy is compared with a linear controller in typical driving situations through simulation, and the control policies trained by drivers with different driving styles are compared using a real driving cycle. Furthermore, the proposed control strategy is demonstrated by a real vehicle-following experiment with different time headways. The simulation and experimental results not only validate the effectiveness and adaptability of the SRL-based CACC system, but also show that it can provide natural following performance like human driving.

Physics-based Character Control Using conditional GAIL

The goal of our research is to control a physics-based character that learns several dynamic motor skills using conditional Generative adversarial imitation learning(GAIL). We present a network-based learning algorithm that learns various motor skills and changing motions between the motor skills from disparate motion clips. The overall framework for our controller is composed of a control policy which generates a character’s behavior, and a discriminator which induces the policy to produce proper motions from a user’s commands. The discriminator and the policy take outputs from each other as input and improve each performance through an adversarial training process. Using this system, when a user commands a specific motion to the character, the character can design a motion plan to perform the motion from the current pose. We demonstrated the effectiveness of our approach through examples with an interactive character that learns various dynamics motor skills and follows a user command in the physics simulation.
On the Influence of Dynamic Illumination in the Perception of Translucency

Translucent materials are ubiquitous in the real world, from organic materials such as food or human skin, to synthetic materials like plastic or rubber. While multiple models for translucent materials exist, understanding how we perceive translucent appearance, and how it is affected by illumination and geometry, remains an open problem. In this work, we analyze how well human observers estimate the density of translucent objects for static and dynamic illumination scenarios. Interestingly, our results suggest that dynamic illumination may not be critical to assess the nature of translucent materials.
