Technological support for distributed agile development

Because of the distance between the dispersed development locations, Global Software Development (GSD) is confronted with challenges regarding communication, coordination and control of the development work. At the same time, agile software development is strongly built upon communication between engineers and has proven its benefits, although, mostly on one single site. As such, it might be advantageous to combine GSD with agile development. This blend however is not straightforward since the distributed and agile development approaches might have conflicting convictions. In this thesis we will discuss the advantages and challenges of combining GSD with agile development based on a literature-based research. The main results presented in the theoretical part of this thesis (Part I through V), are: (i) aspects of agile software development, (ii) benefits and challenges associated with these in relation to GSD, (iii) categories of technological support for agile GSD, (iv) a framework depicting the mutual relations among them and (v) a discussion regarding specific technologies that support collaborative development in relation to this framework. Based on one of the recommendations we make in the theoretical part of this thesis we also perform practical research (Part VI) in which we define a list of requirements for an Integrated Collaborative Development Environment (ICDE) and show the technical feasibility of a number of concepts which realize these.
The Wisdom of Teams: Creating the High-Performance Organization

More and more organizations are using teams and reaping the extra performance results that come with melding skills, experiences and insights of small groups of people working as real teams. Katzenbach and Smith declare teams to be one of the most powerful elements for businesses to meet the challenges of the future - from reengineering to total quality to faultless customer service. Based on hundreds of interviews with team members from a variety of companies and organizations, this book shows why teams work, and explains how to set up and get real results. They provide dozens of real accounts and case studies that illustrate successes and failures, and demonstrate what can be learned from these examples. Douglas K. Smith is the co-author of "Fumbling the Future: How Xerox Invented and Then Ignored the First Personal Computer".
Effect of Usability of Mathematics Laboratory Facilities on the Achievement of Junior Secondary School Students in Number and Numeration

The study focused on the effect of the usability of mathematics laboratory facilities on achievement of students in number and numeration at junior secondary schools in Lagos State, Nigeria. Purposive sampling was used to select two schools in Ikorodu Zone, Education District II and 59 students from two intact classes were selected. The quasi-experimental research design was adopted which involved pre-test and post-test non-equivalent control group. The instrument used for the study was the Number and Numeration Achievement Test (NNAT) which consisted 20 objective questions was adopted from Lagos State Unified Basic Education Certificate Examination past questions validated by Lagos State Ministry of Education Examinations Board. The reliability of the instrument was 0.73 with the use of Spearman rank correlation coefficient. The two research questions raised were answered with the aid of means and Bar-charts, while the three null hypotheses were tested using Analysis of Co-Variance (ANCOVA). The findings revealed that the use of mathematics laboratory enhanced achievement in Number and Numeration unlike conventional method. It also showed that there is no significant effect of gender on the achievement of students taught number and numeration using mathematics laboratory approach. Lastly, there is no significant interaction effect of Mathematics laboratory method and gender on students’ achievement scores. It was recommended that mathematics laboratory should be established, and laboratory approach of teaching mathematics should be adopted in our schools.
Improvement of visual road condition data

The objective of this research, which was carried out between 2010 and 2012, was to investigate the effectiveness of the current road condition rating system with a view to improving the accuracy and confidence in the data collected. This in turn will build confidence in key network performance indicators. The use of visual road condition rating data in New Zealand has evolved from its original purpose of identifying carriageway sections on a network level for treatment and from being employed in the development of a forward works programme. Visual rating data is now used as an input into a series of performance measures and other pavement/surfacing performance modelling. This research project looked at the how the visual rating process is currently undertaken and whether this is appropriate for its current and future uses. With the move towards using the data to compare road controlling authority networks, confidence and consistency in the data is paramount. The research recommends improvements to data collection methodology, rater training, quality auditing, survey stratification and sampling methodology and procurement.
Study of the Hydroponic Barley Effect on the Performance of Feedlot of Calves in the Region Souss Massa (Southern Morocco)

The objective of this research is to investigate the effect of the introduction of hydroponic barley; produced as feed supplement in the ration, on the performance of feedlot calves. This study was performed in the Taroudant region (South of Morocco), during a trial period between July and October 2017). A total of 100 calves were used in a feeding trial, which were divided into two groups. The calves of the first group received a total mixed ration (control), while the calves of the second group received a similar ration with the addition of hydroponic barley.Similar growth performance is observed for the two groups, which is easily explained by the equivalent rationing. In the finishing phase, however, a higher average daily gain is observed for the group fed with an enriched diet in hydroponic green fodder. In fact, the average daily gain for this group amounts to 1.48 Kg/Day compared to 1.42 Kg/Day for the control group.The slaughter results confirm those noted in terms of growth performance, with a relatively similar carcass yield for the two groups.However, since hydroponic fodder reveals a positive impact especially at the level of the finishing phase, it seems judicious to introduce it in the key phases of fattening and finishing in order to perfect the weight gain of the species benefiting from this contribution.The test results suggest that hydroponic barley based rationing is to deepen, and that it would be desirable to repeat the experiment by testing different levels of hydroponic barley intake, adjusting both the type and the level of complementation, with a more accurate monitoring of feeding.

Base compaction specification feasibility analysis.

The objective of this research is to establish the technical engineering and cost analysis concepts that will enable Wisconsin Department of Transportation (WisDOT) management to objectively evaluate the feasibility of switching construction specification philosophies for aggregate base. In order to accomplish this goal, field and laboratory testing programs were conducted on existing Hot Mix Asphalt (HMA) pavements and on base layers under construction as well as comprehensive survey was conducted on highway agencies practices pertaining to base layer construction in the U.S. and Canada. This research proposed construction specifications for aggregate base course layers. The existing HMA pavements that showed early distresses exhibited high levels of spatial variability and non-uniformity in aggregate base course layers, as demonstrated by Falling Weight Deflectometer (FWD) testing and backcalculated base layer modulus. The existing HMA pavements that performed well exhibited low levels of spatial variability and high uniformity in aggregate base course layers, as shown by the FWD test results and the backcalculated base layer modulus. High spatial variability in field density and moisture content exists in base course layers under construction, as demonstrated by the relative compaction test results. In addition, spatial variability and non-uniformity were also demonstrated by the results of the Light Weight Deflectometer (LWD) and GeoGauge, in which the layer modulus varies within a large range of values.
Reverse engineering from 3D mesh to ceramic product in the form of miranda kerr tea for one teapot in PT doulton Indonesia

Abstract The design and manufacturing strategy using reverse engineering (RE) for Miranda Kerr Tea for One Teapot are presented in this paper. A computer-aided reverse engineering system (CARE System) was applied to minimize file errors generated by scanning Miranda Kerr Tea for One Teapot sample products made from Bone China clay. Digital data from the scanning process is used to design a teapot model that is precise and accurate. The digital data generated by Next Engine 3D and the priXa 1588 CMM is then converted into stereolithography (STL) file format (triangle-based data). The process of making 3D CAD models consists of: editing the 3D mesh from the scanning results, 3D CAD design forming the size of the fire, the size of the model, and the 3D CAD milling process using PowerSHAPE with the final result in the form of the surface of each part of the Teapot product. Manufacturing optimization to get the optimal machining strategy used PowerMILL and CNC machines. The casting process becomes a follow-up process after machining the mold of the designed product. This research has succeeded in demonstrating the advantages of using CARE System technology in the national ceramic industry in Indonesia so that it can compete at national and international levels. This is based on the magnitude of the RE error value of less than 1.00 mm with a total processing time of 43 hours 18 minutes 10 seconds and a total cost of about $ 4172.35.
Startup operations and supply chain road guide proposal, based on Robotics Cluster case studies

Concerted efforts are being pursued by governments and economic institutions to promote the generation of startups, and copious documentation has been produced as guides for these emerging companies. However, little has been written on, e.g., the Operations and Supply Chain needs for Hardware Startups, and the development strategy of the required skills to build flexibility during the initial phases of startup development. This work proposes an initial road guide framework for hardware startups, resulting from the experiences of successful companies within the Robotics Cluster present in Massachusetts (either new ventures or spinoffs from existing companies). System Dynamics methodology is then used to capture causal loops, and to characterize the policies which would enable New Venture growth, so as to analyze the Supply Chain/Operations conditions for Hardware Startup Success. The work is presented in four main sections. The first section contains a bibliographic research to characterize the present conditions of Hardware Startups with special emphasis on the Massachusetts Robotics Cluster, providing an overview of the available resources for startups in terms of their skills development and especially with regard to their Operations/Supply Chain Skills development. A second section considered the directed interview of executives at existing robotics startups (Artaic LLC, Kiva Systems, Rethink Robotics and Boston Engineering) to obtain information regarding their strategic decisions in specific aspects of their Supply Chain and Operations. These interviews are reflected as case studies of these companies. The third phase is reflected as a proposal for a System Dynamics model, based on previous work in the area and complemented by aspects identified as relevant from the interviews. Lastly, the conclusions of this work will attempt to gather the main learnings from the analyzed cases, in terms of Operations/Supply Chain Skills development, laying down some directing guidelines for future Hardware Startup ventures.

Towards Improvement in Facilities Operation and Maintenance through Feedback to the Design Team

Direct involvement of the facility manager in the design stage has the potential to reduce maintainability problems during the operational phase of a facility. The objectives of this paper are to investigate the role of the facility manager towards the provision of easily maintainable projects; and propose an approach for fostering new avenues of collaborations among various professionals in the design team. A critical review of the literature has been carried out for the purposes of understanding the effects of design on facilities operation and maintenance. The paper critically analyses the current approach followed in the design of building projects; and explores the range of contributions that the facility manager could offer, during the design phase, towards facilities maintenance management. Based on the survey of literature, it has been established that the majority of maintenance problems in a facility is not attributed to construction problems, but rather to design problems. It also reveals that the contribution of the facility manager is not considered by the integrated design team, and there exists no specific role that could be assigned to the facility manager. The paper has consolidated the duties of the facility manager in the architectural design process in order to provide easy maintenance management and quality improvement of the facility. The involvement of the facility manager with the integrated design team if implemented efficiently will contribute in reducing the need for major repairs and alterations in the lifespan of the facility.
Mathematical modelling of shallow flows: Closure models drawn from grain-scale mechanics of sediment transport and flow hydrodynamicsThis paper is one of a selection of papers in this Special Issue in honour of Professor M. Selim Yalin (1925–2007).

Mathematical modelling of river processes is, nowadays, a key element in river engineering and planning. River modelling tools should rest on conceptual models drawn from mechanics of sediment transport, river mechanics, and river hydrodynamics. The objectives of the present work are (i) to describe conceptual models of sediment transport, deduced from grain-scale mechanics of sediment transport and turbulent flow hydrodynamics, and (ii) to present solutions to specific river morphology problems. The conceptual models described are applicable to the morphologic evolution of rivers subjected to the transport of poorly sorted sediment mixtures at low shear stresses and to geomorphic flows featuring intense sediment transport at high shear stresses. In common, these applications share the fact that sediment transport and flow resistance depend, essentially, on grain-scale phenomena. The idealized flow structures are presented and discussed. Numerical solutions for equilibrium and nonequilibrium sediment tran.
Sound Source Localization and Beamforming for Teleconferencing Solutions

In teleconferencing the audio quality is key to conducting successful meetings. The conference room setting imposes various challenges on the speech signal processing, such as noise and interfering signals, reverberation, or participants positioned far from the telephone unit. This work aims at improving the received speech signal of a conference telephone by implementing sound source localization and beamforming. The implemented microphone array signal processing techniques are compared to the performance of an existing multi-microphone solution and evaluated under various conditions using a planar uniform circular array. Recordings of test-sequences for the evaluation were performed using a custom-built array mockup. The implemented algorithms did not show good enough performance to motivate the increased computational complexity compared to the existing solution. Moreover, an increase in number of microphones used was concluded to have little or no effect on the performance of the methods. The type of microphone used was, however, concluded to have impact on the performance and a subjective listening evaluation indicated a preference for omnidirectional microphones which is recommended to investigate further.
Job Stress on Teachers During the Covid-19 Pandemic: The Role of Workload and Organizational Climate

The number of workloads borne by the teacher will result a negative impact. An organizational climate is crucial because it can generate a comfortable working conditions for teachers. Otherwise, an unfavorable organizational climate can impact poor working conditions that affect teachers to experience job stress. This study aimed to determine the effect of workload and organizational climate on the work stress of elementary school teachers in Indonesia. One hundred forty-eight elementary school teachers were selected as research participants through an incidental sampling. The research instruments were the workload scale, organizational climate scale, and teacher job stress scale. The results of regression analysis revealed that workload (β = 0.134, p = 0.026) and organizational climate ( = -0.680, p = 0.000) contributed to the job stress of elementary school teachers. This study recommends primary school principals to manage the workload for the professionalism improvement and productivity of elementary school teachers. Harmony in the school environment must be maintained to create a comfortable work and avoid work stress.
Face learning via brief real-world social interactions induces changes in face-selective brain areas and hippocampus

Making new acquaintances requires learning to recognise previously unfamiliar faces. In the current study, we investigated this process by staging real-world social interactions between actors and the participants. Participants completed a face-matching behavioural task in which they matched photographs of the actors (whom they had yet to meet), or faces similar to the actors (henceforth called foils). Participants were then scanned using functional magnetic resonance imaging (fMRI) while viewing photographs of actors and foils. Immediately after exiting the scanner, participants met the actors for the first time and interacted with them for 10 min. On subsequent days, participants completed a second behavioural experiment and then a second fMRI scan. Prior to each session, actors again interacted with the participants for 10 min. Behavioural results showed that social interactions improved performance accuracy when matching actor photographs, but not foil photographs. The fMRI analysis revealed a difference in the neural response to actor photographs and foil photographs across all regions of interest (ROIs) only after social interactions had occurred. Our results demonstrate that short social interactions were sufficient to learn and discriminate previously unfamiliar individuals. Moreover, these learning effects were present in brain areas involved in face processing and memory.

Understanding the Skill Provision in Gig Economy from A Network Perspective

The recent emergence of gig economy facilitates the exchange of skilled labor by allowing workers to showcase and sell their skills to a global market. Despite the recent effort on thoroughly examining who workers in the gig economy are and what their experience in the gig economy are like, our knowledge on how exactly do workers provide their skills in gig economy, and how worker's strategies on skill provision and expansion relate to their success in gig economy is still lacking. In this paper, we conduct a case study on a prominent gig economy platform, Fiverr.com, to better understand the provision of skills on it through large-scale, data-driven analysis. In particular, we propose the concept of "skill space" from a network perspective to characterize the relationship between different skills by measuring how frequently workers provide different skills together. Through our analysis, we reveal interesting patterns in worker's provision of skills on Fiverr. We then show how these patterns change over time and differ across subgroups of workers with different characteristics. In addition, we find that providing a set of skills that are highly related with each other correlates with a better overall performance in gig economy, and when workers expand their skillsets, expanding to a new skill that is highly-related to the existing skills takes less time and is associated with better performance on the new skill. We conclude by discussing the implications of our findings for gig economy workers and platform in general.
