Estimating the value of IT Project Governance

This paper synthesises prior research findings to highlight how few IT projects realise all their expected benefits despite the widespread use of project management and technical methodologies. Using plausible assumptions derived from research the paper suggests only a third of IT projects currently deliver any benefits at all and that overall ROI is around 30%. It suggests IT Project Governance has the potential to increase ROIs to 135-240%. A large organisation that spends $30M pa on IT might realise an additional $10.5M to $21M pa, and nationally GDP might be lifted by 1.6% to 3.1%. Further research is suggested.
Modifying and Translating the Beginning College Survey of Student Engagement for Use in Saudi Arabia: The Difficulty of Validation

Student engagement in the first year of university plays a vital role on retention, learning, and persistence in STEM fields. The Beginning College Survey of Student Engagement (BCSSE) measures student engagement during their first year of university and was constructed and validated for use in the English language. In Saudi Arabia, the first year of university aims to smooth students’ transition from secondary to higher education. However, many students struggle with this transition and experience challenges to adjust. Therefore, a similar questionnaire to the BCSSE is needed to implement an exploratory study that measures student engagement during their first year of university in Saudi Arabia. To do so, some items of the BCSSE were modified and translated into the Arabic language. The process of providing evidence for validity, utilizing a forward-backward translation technique, is outlined here. Initial translation was done by the author. Face validity was obtained using multiple Arabic and English speakers. A total of 71 Saudi students completed the survey, and the internal consistency was tested using a Cronbach’s α -coefﬁcient. Eight Saudi students participated in cognitive interviews to provide additional information regarding validity of the survey items. This paper discusses some of the problems encountered in each stage of validation. The translated survey was revised to a final Arabic version based on students’ suggestions and will be tested for reliability with a future sample.

AUTOTRACKER: AUV embedded control architecture for autonomous pipeline and cable tracking

This paper concentrates on one probably most commercially significant AUV applications: embedded cable and pipeline tracking. A modular approach to this problem has been adopted as the AUTOTRACKER project. The research and development is partially funded by the European Union and companies within the offshore industry. The system is being demonstrated and evaluated on real offshore pipelines and cables using a commercial Survey-AUV. This paper describes AUTOTRACKER's modular, distributed software architecture. It then outlines the sensor and processing techniques used for real-time control of the AUV to perform tracking and obstacle avoidance. In addition, details of the system tests and practical trials used in the development process are outlined.
The Machine in Me: An Anthropologist Sits Among Computer Engineers

From the Publisher: Gary Lee Downey investigates the body/machine interface in his remarkable ethnography of computer engineers. Drawing on interviews, observations and personal interaction with engineers, he documents the everyday power of technology's dominant image in our society, a force widely regarded as monolithically progressive. The Machine in Me will lead the reader to understand how deeply connected we are to The Machine and how beneficial it would be for us to really understand ourselves and machines as partially configured of the other--we as part machine, machines as part human. In this way, we can begin to see both the power and limitations of technology.
Development of a Simplified Performance-Based Procedure for Assessment of Liquefaction Triggering Using Liquefaction Loading Maps

Development of a Simplified Performance-Based Procedure for Assessment of Liquefaction Triggering Using Liquefaction Loading Maps Kristin Jane Ulmer Department of Civil and Environmental Engineering, BYU Master of Science Seismically-induced liquefaction has been the cause of significant damage to infrastructure and is a serious concern in current civil engineering practice. Several methods are available for assessing the risk of liquefaction at a given site, each with its own strengths and limitations. One probabilistic method has been shown to provide more consistent estimates of liquefaction risk and can be tailored to the specific needs of a given project through hazard-targeted (i.e. based on return periods or likelihoods) results. This type of liquefaction assessment is typically called “performance-based,” after the Pacific Earthquake Engineering Research (PEER) Center’s performance-based earthquake engineering framework. Unfortunately, performance-based liquefaction assessment is not easily performed and can be difficult for practicing engineers to use on routine projects. Previous research has shown that performance-based methods of liquefaction assessment can be simplified into an approximation procedure. This simplification has successfully been completed for the Cetin et al. (2004) empirical, probabilistic standard penetration test -based liquefaction triggering model. Until now, such a simplification has not been performed for another popular liquefaction triggering model developed by Boulanger and Idriss (2012). As some engineers either wish to use or are required to use the Boulanger and Idriss (2012) model in their liquefaction assessments, there is a need for a simplified performance-based method based on this model to supplement that based on the Cetin et al. (2004) model. This thesis provides the derivation of a simplified performance-based procedure for the assessment of liquefaction triggering using the Boulanger and Idriss (2012) model. A validation study is performed in which 10 cities across the United States are analyzed using both the simplified procedure and the full performance-based procedure. A comparison of the results from these two analyses shows that the simplified procedure provides a reasonable approximation of the full performance-based procedure. This thesis also describes the development of liquefaction loading maps for six states and a spreadsheet that performs the necessary correction calculations for the simplified method.
The Cost‐Effectiveness of Water Conservation

The Town of Cary, North Carolina, has found that a carefully planned water conservation program can offer real solutions to real problems. By making the most of existing water supplies, Cary's conservation efforts have helped create a “new” source of water and enabled the town to delay two future plant expansions by a total of 10 years, at a cost of $138/mil gal ($37/ML) of water saved. This paper offers an overview of Cary's long‐term water conservation program and its associated costs and benefits.
Automated Underwater Hull Maintenance Vehicle

Abstract : The maintenance and repair of the underwater hulls of Navy ships is expensive and labor intensive. While the introduction of effective epoxy anticorrosive paints and improved ablative antifouling paints have contributed to lengthening the time between dyrdocking, needed repair work is often not discovered until the ship is in drydock. In addition, the U.S. Navy has implemented cuprous oxide containing ablative antifouling paints to replace the standard antifouling paint (F 121) in the fleet. While the ablative antifouling paints are performing better than the F 121, some fouling of these paints has been reported. The process of underwater hull cleaning therefore has the potential to discharge unacceptable amounts of copper toxicant into Navy harbors. An underwater vehicle designed to perform a multitude of hull husbandry tasks is under development at the Annapolis Detachment of the Carderock Division, Naval Surface Warfare Center. This vehicle, which has its roots in remotely operated vehicle technology, would have the capability to self-navigate around the hull while recording data on hull systems, such as paint thickness, hull plate thickness, and cathodic protection potentials. These data would allow planners to determine how much ablative AF paint needs to be applied at the next docking to track the average hull thickness and to monitor the health of the impressed current cathodic protection system. This will reduce maintenance costs in drydock. In addition, the vehicle would have the capability to detect the presence of significant marine fouling, which increases hydrodynamic drag and fuel consumption.

Research method: The application of the system based on multi-criteria analysis, through the method of hierarchical analysis, according to previously established criteria, enables decision-making based on multiple criteria. Main findings: The criteria generated by the mathematical process presented the priorities of heat treatment technologies and energy potential according to the levels of preference and order of importance. Implications for theory and practice: The production refused derived fuel replaces petroleum-derived fuel sources, and reduces the amount of waste disposed of in landfills.
Systemtyper utanför ramen för både traditionell systemutveckling och e-infrastrukturutveckling : Finns de och hur bör de i så fall utvecklas?

The purpose of this study is to examine if there's a type of system which properties reminds of both traditional systems and e-infrastructures without belonging to either of the two. How a design model for development of this kind of system looks will also be examined. The kind of system is what we refer to as a borderline system. To examine this traditional systems and E-infrastructures and their development methods have been analyzed in order to see if there is some kind of system in between the two endpoints. And if there is something there, how a design model for this kind of borderline system would look. A case study was applied to see how well the theoretical design model was applicable to practical system development. Results of the study show that there in fact is a type of system, which do not fit in the frames of neither traditional systems nor e-infrastructures. It also showed that the design model could be applied during development of this kind of system. During the development many of the design principles were found irrelevant. The definition of borderline systems was also only applicable for some parts of the developed system. The definition of borderline systems were then reformed to:- The first version of the system contains only a few but through thought functions that generate direct usefulness. - Which functions that will be added in later versions will be decided by the need of these functions that is expressed by the users during the operating time of the system.The study presents design rules, which in the development process solved the problems that were found and linked to the specific properties of the redefined version of the borderline system definition.
Comportamento das atividades setoriais nos municípios gaúchos entre 1970 e 2000

The present work studies the behaviour of activities among sectors in Rio Grande do Sul from 1970 to 2000 using a new aggregation methodology, which was developed by de Economy and Statistical Foundation. Such methodology allows having the same number of municipalities along the studied period (232 municipalities). Adding to that, the paper analysis the evolutions of labour market through a set of indicators such as location indicators, specialization indicators. Despite of that we used the structural-diferencial methodology to analyse the sources of job improvement inside the municipalities. The results show a significant transformation process in productive activities. There was improvement in manufacture, civil construction and services. However, the structural-differential methodology showed that the most important aspect to improve the occupation in the municipalities was the competition degree of the municipality, evem if it wasn’t similar among than. Key words: Conversion System, Employment, sector activities
Science for Global Ubiquitous Computing

This paper describes an initiative to provide theories that can underlie the development of the Global Ubiquitous Computer, the network of ubiquitous computing devices that will pervade the civilised world in the course of the next few decades. We define the goals of the initiative and the criteria for judging whether they are achieved; we then propose a strategy for the exercise. It must combine a bottom-up development of theories in directions that are currently pursued with success, together with a top-down approach in the form of collaborative projects relating these theories to engineered systems that exist or are imminent.
3.7 mW 24 GHz LNA with 10.1 dB gain and 4.5 dB NF in 0.18 μm CMOS technology

A low-power 24 GHz low-noise amplifier (LNA) with flat and low noise figure (NF) using standard 0.18 µm CMOS technology is demonstrated. The low-power LNA consists of three cascaded common-source stages biased in the weak inversion region. To achieve sufficient gain, a series peaking inductor (LG3) was added to the input terminal of the third stage to boost the gain (simulation shows a 78.9% improvement (from 5.7 to 10.2 dB) at 24 GHz). Flat and low NF was achieved by adopting a slightly under-damped Q-factor for the second-order NF frequency response. Shunt RC feedback in conjunction with a low-Q RL load were adopted in the third stage to achieve excellent output impedance matching. The 24 GHz LNA achieved S21 of 10.1 dB and NF of 4.5 dB with a power dissipation (PDC) of only 3.7 mW, the lowest PDC ever reported for a 24 GHz-band CMOS LNA with S21 greater than 10 dB.

RESTRICCIÓN DE ALIMENTO DIURNO REDUCE MUERTE POR CALOR EN GRANJAS AVÍCOLAS COMERCIALES Diurnal Feed Restriction Reduces Death by Heat in Commercial Poultry Farms

The effects of both food restriction (FR) and non food restriction (NFR) in Ross broilers under commercial conditions in Cagua, Venezuela, were evaluated. At 28d of age broilers, circular fences were placed in the shed and a total of 264 broilers, half males (M), half females (F) was randomly selected and allocated into two groups that underwent two experiments (EXP): Experiment 1 (EXP1): 120 broilers; Experiment 2 (EXP2): 144 broilers. The FR lasted 7h (9:00 to 16:00h) in both EXP. The following were measured: environmental temperature (ET); body temperature (BT), hyperventilation level (HL), food consumption (FC), weight gain (WG), food conversion index (FCI), and mortality. In EXP1, BT and HL were measured in an alternate way from 30 to 40d of age. In EXP2, they were measured in parallel between 29 and 38d of age. The average ET within the shed was 29.4°C (EXP1) y 30.9°C (EXP2), 1.4°C to 2°C higher than outside it. The FC was superior in M in both EXP, but the differences were lower among sexes in broilers under FR (EXP1), although non significant. No effect on WG and FCI was found in EXP2. In EXP2, the mortality reached 24.3% (35/144) at d 35 (alleged heat stress), with 75% more in FR than in NFR broilers; with a 50% more in M compared to F with FR. In EXP2, M had a higher (0.22°C) BT than F, being the most important differences in broilers with NFR food. In general, FR reduced HL in 19.8 insp/min in EXP1 and 12.3 insp/min in EXP2, respectively. The sex did not have any effect on HL in EXP2, although it was more important for F (29.1 insp/min) than for M (10.6 insp/min) in EXP1. The reduction in the risk of mortality due to heat stress was greater in F.
5G： Vision, Scenarios and Enabling Technologies

This paper presents the authors’ vision for 5G wireless systems, which are expected to be standardized around 2020(IMT-2020). In the future, ubiquitous service will be the key requirement from an end-user’s prospective, and 5G networks will need to support a vast mesh of human-to-human, human-to-machine, and machine-to-machine connections. Moreover, 5G will need to support these connections in an energy-efficient manner. Various 5G enabling technologies have been extensively discussed. These technologies aim to increase radio link efficiency, expand operating bandwidths, and increase cell density. With these technologies,5G systems can accommodate a massive volume of traffic and a massive number of connections, which is fundamental to providing ubiquitous services. Another aspect of 5G technology is the transition to an intelligent cloud that coordinates network access and enables flatter architecture.

Solutions to the equivalent mutants problem : A systematic review and comparative experiment

Context: Mutation testing is a fault-based technique for measuring the effectiveness of a test set in terms of its ability to detect faults. Mutation testing seeds artificial faults into an application and checks whether a test suite can detect them. If these faults are not found, the test suite is still not considered to be 'good enough'. However, there are also mutations which keep the program semantics unchanged and thus cannot be detected by any test suite. Finding a way to assess these mutations is also known as the equivalent mutant problem (EMP). Objectives: The main objective of this thesis is to conduct a systematic literature review in the field of mutation testing, to identify and classify existing methods for equivalent mutants detection. In addiction, other objectives are: analyze possibilities to improve existing methods for equivalent mutant detection, implement new or improved method and compare it with existing ones. Methods: Based on the systematic literature review method we have went over publications from six electronic databases and one conference proceedings. Standard method was extended by scanning lists of references and some alternative sources: searching in Google Scholar, checking personal websites of relevant authors and contacting all of them. We have performed all the systematic literature review steps such as the protocol development, initial selection, final selection, quality assessment, data extraction and data synthesis. In the second part of this thesis - an experiment, we have implemented four second order mutation testing strategies and compared them each other from four different perspectives: mutants reduction, equivalent mutants reduction, fault detection loss and mutation testing process time reduction. Results: The search identified 17 relevant techniques in 22 articles. Three categories of techniques can be distinguished: detecting (DEM), suggesting (SEM) and avoiding equivalent mutants generation (AEMG). Furthermore, for each technique current state of development and some ideas on how to improve it are provided. The experiment proved that DifferentOperators strategy gives the best results in all four investigated areas. In addition, time for manual mutants classification against equivalence was measured. Assessing one first order mutant takes 11 minutes 49 seconds, while for the second order mutants classification time is 9 minutes 36 seconds in average. Conclusions: After three decades of studies, results obtained for techniques from the DEM group are still far from perfection (best one is detecting 47,63% of equivalent mutants). Thus, new paths for the solution have been developed - SEM and AEMG group. Methods from both categories help in dealing with EMP, however from SEM provide only mutants likely to equivalent, while from AEMG cause some loss of test effectiveness. The conclusion from the experiment is that DifferentOperators strategy gives the best results among all proposed.
Questioning the net generation: a collaborative project in Australian higher education

This paper describes a project, which has been supported by the Carrick Institute for Learning and Teaching in Higher Education, that aims to identify how the technologybased tools of a new generation of students can be successfully used by higher education. Recent commentaries propose that Universities are ill-equipped to educate a new generation of learners whose sophisticated use of emerging technologies is incompatible with current teaching practice. This project will investigate this proposed gap between learners’ and teachers’ use of technologies and identify the implications for higher education. This paper presents the rationale of the project, highlighting its critical stance on current notions of the ‘Net Generation’. The three phases of the project – Investigation, Implementation and Dissemination – are then described. The project will be undertaken as a collaboration between staff at The University of Melbourne, the University of Wollongong and Charles Sturt University. In the final stages of the project, members of the ascilite community will be able to participate in practical workshops based on the lessons we have learned from questioning the ‘Net Generation’.
