Comparison between Agile and Traditional software development methodologies

Abstract. This paper is a review research about the features of the agile and heavy (traditional) software development methodologies and comparisons between them based on: Approach, Success Measurement, Project size, Management Style, Perspective to Change, Culture, Documentation, Emphasis, Cycles, Domain, Upfront Planning, Return on Investment and Team Size. The important difference between agile and heavy methodologies is the adaptability for project changes. In agile methodologies changes do easily but heavy methodologies are static and do not adapt with changes. Also in this paper there are the usage of each groups of methodologies and how can work two groups together. In addition, some types of heavy and agile methodologies have been described.
Accounting Teachers’ Voices on Factors Affecting Online Teaching during the 4th Industrial Revolution in the Face of COVID-19 in Selected High Schools in the Eastern Cape, South Africa

The most prominent debate in South Africa is how teachers will provide instruction online. The purposes of this article was to explore Accounting teachers’ voices on factors affecting online teaching. To this end, the researchers employed a qualitative approach and a case study research design. Interviews were used as a method to collect data from 10 Accounting teachers who were purposively selected. Thematic data analysis was used. The results revealed that, Accounting teachers are lacking required knowledge and skills needed to facilitate technology learning in their classrooms. Results further reveal that, online teaching arrived at an awkward moment when teachers were faced with COVID-19 pandemic. The study concludes that teachers’ voices play an important role in any proposed changes in the classroom. The Eastern Cape Province where the study was conducted should quickly roll out infrastructure at all schools aiming to support online classrooms. It is recommended in this paper that teachers need to be workshopped in online teaching in order for them to perform effectively.
Babungo : a study of iron production, trade and power in a nineteenth century Ndop plain chiefdom (Cameroons)

A survey of smelting debris undertaken in BABUNGO brought to light what is to date the largest single recorded centre of iron production in sub-Saharan Africa. High output in the 19th century was facilitated by innovation in furnace structure that enhanced capacity and brought in economies of scale along with changing fuel usage that enabled the intensification of production by a sedentary industry set within a grasslands environment. Elsewhere in the region separate smithing and smelting using older, smaller furnaces exploiting traditional fuels and ores collapsed and in its place arose a devolved technology centring on recycling of slag in simple open hearth furnaces. The enormous output of the BABUNGO industry was linked to a mode of labour recruitment and division of rewards that overrode the boundaries of the kin group. At the point of establishment of the foundry and throughout its operation non-kin freely offered their labour in return for access to the foundry. A pervading ethos of cooperation and stress on the sharing of the product in terms of a familial paradigm provided for the social validation of the accumulation of wealth by individual descent group heads. The distribution of products was characterised by periodic markets, organised trading groups, use of convertible currencies, credit and commissions. The heavy costs of transporting ironware to regional markets was largely taken over by specialist trading chiefdoms that clustered around BABUNGO. Unencumbered by these costs output rose to even higher levels. The great material wealth generated by iron production was further enhanced by the highly profitable conveyances to be made between continental and coastal spheres of trading activity that abutted on the Grassfields. The political organisation of BABUNGO offered only limited opportunity for conversion of wealth into political authority. The integrity of the chiefdom barely withstood the internal pressures generated by the enormous wealth derived from iron production but was bolstered by an external alliance undertaken by an astute FON with the vanguard of German colonisation.
Comparison of Dominant and Non-dominant Range of Motion in Collegiate Baseball Pitchers: A Pilot Study

Shoulder injuries may be prominent in baseball pitchers due to inflexibility of the shoulder and trunk. Differences may exist between pitchers' dominant and non-dominant shoulders and trunk. The purpose of this pilot study was to confirm prior research to compare dominant and non-dominant shoulder and trunk range of motion in fifteen (n = 15, 18-23 yrs.) collegiate pitchers. Trunk range of motion was measured using the Y-Balance Test. A goniometer was used to assess seven measurements of shoulder range of motion. Paired sample t-tests were used to determine statistical significance (p < .05). Shoulder extension (t (14) = -3.02, p = . 009), internal rotation (t (14) -2.8, p = . 013), horizontal abduction (t (14) =-2.17, p = . 047), and Y-Balance Test (t (14) = -2.2, p = . 044) were significantly greater in the non-dominant arm. The findings of our study suggest collegiate baseball coaches and trainers should create strength and conditioning programs that are balanced and focus on both dominant and non-dominant shoulder and trunk range of motion.
The Risk of Cardiac-related Mortality in Stage IIIA-N2 Non-small Cell Lung Cancer: Analysis of the Surveillance, Epidemiology, and End Results Database

Background: We aimed to investigate the association between postoperative radiotherapy (PORT) and cardiac-related mortality for patients with ⅢA-N2 non-small cell lung cancer (NSCLC) by the Surveillance, Epidemiology, and End Results (SEER) database.Methods: The United States (US) population based SEER database were queried for cardiac-related mortality among patients with ⅢA-N2 NSCLC. Cardiac-related mortality was compared between PORT and Non-PORT group. Accounting for mortality from other causes, Gray’s test compared cumulative incidences of cardiac-related mortality between both groups. Univariate and multivariate analysis were performed using the competing risk model.Results: From 1988 to 2016, 7290 patients met the inclusion criteria: 3386 patients treated with PORT and 3904 patients treated with Non-PORT. The 5-year overall incidence of cardiac-related mortality was 3.01% in PORT group and 3.26% in Non-PORT group. Older age, male sex, squamous cell lung cancer, earlier year of diagnosis and earlier T stage were independent adverse factors for cardiac-related mortality. However, PORT use wasn’t associated with an increase in the hazard for cardiac-related mortality (subdistribution hazard ratio [SHR]=0.99, 95% confidence interval [95% CI], 0.78–1.24, p=0.91). When evaluating cardiac-related mortality in each time period, the overall incidence of cardiac-related mortality was decreased over time. There were no statistically significant differences based on PORT use in all time periods.Conclusions: With a median follow-up of 25 months, no significant differences were found in cardiac-related mortality between PORT and Non-PORT for ⅢA-N2 NSCLC patients.
Manufacturing Back-Reshoring - An Exploratory Approach for Hypotheses Development

Over the past years, use of the terms like “on-shoring”, “re-shoring” and “back-shoring” has multiplied dramatically, especially in economics journalism and in consulting firms’ white papers. More recently, the topic has also attracted academic attention. Notwithstanding this increasing attention, reliable and quantitative evidence on the extent of the back-shoring phenomenon is scanty and often of anecdotal nature. Moreover, definition and characterization of such a phenomenon are still not definitive. In this paper, we focus our attention on the theoretical conceptualization of the back-reshoring phenomenon and summarize the base of knowledge currently available. At the same time, we formulate an operative definition of the investigated phenomenon within a comprehensive theoretical framework. We also define a set of research proposals to be analysed in future research, on the basis of both, a literature review and preliminary evidence provided by our dataset “Uni-CLUB MoRe Back-reshoring”, developed as part of a research project jointly undertaken by scholars belonging to the Universities of Catania, L’Aquila, Udine, Bologna and Reggio Emilia.

Mine site village carbon emissions & engineering offset solutions

This report aims to investigate solutions for carbon neutrality in mine site village developments by assisting David Goodfield (DG) in undertaking several essential tasks associated with his PhD, using Mount Magnet Gold (MMG) village as a case study. In order to assess the potential of Renewable Energy (RE) as a carbon offset solution in the current power system, software called REMAX was specially developed. HOMER was used to assess the potential of RE in standalone power systems. A standalone study was undertaken, as major capital cost savings were identified if the transmission line between the mine power system and the village was removed (≈$250,000 per kilometre). The sensitivity of MMG village’s power system, being the mine’s power system was found to be somewhere between 50 and 100 kW. Due to these sensitivities and the small ratio of the village within the load (2.46%), it was found that the potential of RE in the current power system would be very low. The standalone configuration was found to be more economically viable than the current power system, if the village is located more than 4 kilometres (km) away from the mine power system (assuming cost of the line ≈$250,000 per kilometre). Findings also show that a wind diesel hybrid power system is more economically viable than the diesel, only if the project life is more than 7, 5, 4 and 3 years for a project starting in January 2012, 2014, 2016 and 2018 respectively. However, in the situation where the standalone system is powered by only diesel generators, the carbon emission was found to be higher and was not suitable for this project. Given the high energy usage of mining villages’ air conditioning (AC) systems, the potential of using a Ground Source Heat Pump (GSHP) system instead of currently used standard reverse cycle AC systems was also investigated. GSHPs were found to have a high potential as a carbon offset solution in mine site villages, with payback period under six years possible. Nevertheless, the system needs to be sized appropriately and used in high demand locations (≈20 hours a day). Another task associated with this project was to undertake the village’s energy audit and monitoring system commissioning which were successfully undertaken during a site visit in the third week of October 2011. Also, the calculation of the embodied energy of two buildings (donga and kitchen) from the village was undertaken using a life cycle assessment software (eTool), that was previously investigated.
Experimental and numerical investigations on an automotive turbocharger with a transparent bearing section

The dynamic behaviour of an automotive turbocharger supported with full floating ring bearings is investigated experimentally and numerically. The rotor orbit on compressor side and, after modifying the turbocharger’s housing, the rotational speed of the floating ring are investigated by the measurement. To determine the ring’s rotational speed, the housing of the journal bearing section has been rebuilt employing a transparent synthetic material. The floating ring on the compressor side is now visually accessible. Using a high-speed camera and a subsequent image analysis in M atlab , the communication holes around the circumference of the floating ring are detected and the rotational speed can be calculated afterwards.
Mathematical analysis of PWM processes

Pulse width modulation (PWM) inverters convert a direct current (DC) power supply to an alternating current (AC) supply by means of high frequency switching between two DC sources. Undesirable high-frequency components are generated in the frequency spectra of the voltages and currents of PWM inverters. The high-frequency components are ultimately removed from the input and output waveforms by filters. PWM inverters are used in a wide variety of electrical devices, ranging from microwave ovens to the electrical parts of aircraft. In many of these devices, minimising the size and weight of the electrical parts is important, and, consequently, it is desirable to design efficient filters for PWM inverters. Identification of the unwanted high-frequency components allows for optimal filter design. In this thesis we use alternative methods to calculate the voltages and currents of PWM inverters. Mathematical models are developed for several PWM inverter designs, and Fourier analysis of the mathematical expressions for the currents and voltages allow us to determine frequency spectra. The methods used in this thesis are shown to be more suitable to the calculation of spectra for complex inverter designs, compared to conventional techniques. In particular, input current spectra are calculated for PWM inverters that incorporate dead time and space vector modulation (SVM) inverters for the first time here.

Mapping of Real-time Applications on Network-on-Chip based MPSOCS.

Mapping of real time applications on real time NoC based MPSoCs. With the recent developments in semiconductor technology it becomes possible to integrate many different processing elements on single chip, this solution is known as a System-on-Chip (SoC). In such systems, the communication between the different components is also an important aspect. On-chip busses or point-to-point communications have been successfully used. However, as the number of elements increases, on-chip busses are not able to scale and quickly become a communication bottleneck. Packet-switched networks on chip (NoC) have been proposed as a solution for on-chip communication of SoC platforms overcoming many of the limitations of on-chip buses. An important design aspect in such a system is the relative placement of tasks on the processing elements of the platform so that some metrics of interest are optimised commonly referred to as the mapping problem. NoC platforms, because of the benefits that they introduce, will eventually be used in commercial embedded and real-time systems. Despite its significance to embedded systems industry and research communities, little research has been done on providing guarantees for hard real-time applications composed of multiple communicating components running over NoC platforms, in such systems both the computation and the communication between the components must complete within certain deadlines for the system to behave correctly. Application mapping has a direct impact on the interference patterns emerging on the platform where separate tasks and the communications between them interfere with each other when contending over shared resources. Even though a significant amount of research has been carried out on the mapping problem usually the aim is to optimise different metrics and reduce cost in terms of energy consumption. This work tries to solve the mapping problem from a real-time systems perspective, in such systems the overall correctness does not only depend on producing the correct output but also on the time required by the system to produce it, this requirement is most commonly expressed with the concept of a deadline which must always bound the response time of a computational task. Schedulability analysis refers to a set of analytical methods that are able to prove a set of tasks can meet their deadlines when sharing resources under a particular scheduling scheme. This work takes advantage of recent advancements on schedulability analysis that can guarantee the timeliness of tasks, as well as their communications, in distributed real-time systems which specifically run on network on chip platforms using wormhole routing, this analysis is used as a ranking function in a genetic algorithm that is able to evolve task mappings which allow all tasks and communication flows to meet their deadlines in all possible scenarios.
