PTTI 2030 - Time Transfer and Applications in 2030

Abstract : Current Time-Transfer techniques using Two Way Satellite Time Transfer (TWSTT) and Global Positioning System (GPS) Carrier-Phase differencing offer excellent Precise Time and Time Interval (PTTI) accuracy and stability for only a few high technology laboratories and weapon systems. Today's costs of these systems impede their use in systems where performance gains are possible. However, future research and development will likely extend today's leading edge PTTI capabilities economically to greater numbers of laboratories, systems, and users in the years to come. This poster examines the potential future applications of much improved mainstream time transfer and hyper-accurate time transfer for precise applications, as well as identifying foreseen potential hurdles along the way.
Project supply chain management: From agile to lean

More than forty years has passed since the start of the North Sea oil and gas developments. On the managerial side of the projects there have been large cost overruns, project planning and control measures developed to avoid these, initiatives to improve the industry’s competitiveness in the North Sea, as well as measures to improve the supply chains contribution in the projects. We have seen a focus first and foremost on the CAPEX side of the projects, which still is the public measure of a ‘project’s’ success as seen in medias coverage. However, the operation side of the project has been given extended focus, especially through life-cycle cost measures, and life cycle value measures trying to balance out the CAPEX, OPEX and income sides of the project to obtain the most commercial value enhancement from each project. At the same time there has been an increasing focus on the core business among the project demand and supply chain actors in this industry as in most other industries.Our belief is that this necessitates an enhanced focus on the project demand and supply chains of the industry, both for the projects development and operations phases. A question is whether the project demand and supply chain developments are approached appropriately according to the characteristics of the industry’s project context?
Phenomenological control: response to imaginative suggestion predicts measures of mirror touch synaesthesia, vicarious pain and the rubber hand illusion

[Published in Nature Communications as Trait phenomenological control predicts experience of mirror synaesthesia and the rubber hand illusion] The control of top down processes to generate experience has been studied within the context of hypnosis since the birth of psychological science. In hypnotic responding, expectancies arising from imaginative suggestion drive striking experiential changes (e.g., hallucinations) – which are experienced as involuntary – according to a normally distributed and stable trait ability (hypnotisability). Such experiences can be triggered by implicit suggestion and occur outside the hypnotic context. The possibility that they account for experiential change in psychological studies has been overlooked. In large sample studies (of 156, 404 and 353 participants) we report substantial relationships between hypnotisability and experimental measures of experiential change (mirror-sensory synaesthesia and the rubber hand illusion) comparable to relationships between hypnotisability and individual hypnosis scale items. The control of phenomenology to meet expectancies arising from perceived task requirements can account for experiential change in psychological experiments.
Bandwidth Analysis of a Jerusalem AMC Based on Equivalent Circuit Model

The bandwidth of a Jerusalem AMC was investigated based on the equivalent circuit model. Using the circuit model and the derivative of the admittance(Y'), the relation between the bandwidth and various circuit parameters was analyzed. It was shown that the substrate thickness and permeability enhance the bandwidth whereas the loadings on FSS grid degrade the bandwidth. Among the two loadings, the capacitive loading had better bandwidth characteristics than the inductive loading. AMC with single polarization was suggested to relax the bandwidth degradation by the inductive loading.
Extraction and Preliminary Phytochemical Analysis of Different Extracts of Cassia Fistula Linn. Pods

Aims and Objectives: The presence of active chemical compounds in natural sources can help to target plants for their therapeutic activities. Here, chemical scrutiny of Cassia fistula through phytochemical testing was performed using different solvents and checked for presence of chemical classes present in it. The aim of study was to identify the possible therapeutic components in pods of C. fistula (fresh and dried forms) and their concentrations in following two different solvents methanol and distilled water. Methodology: The crude extracts obtained from the young pods of C. fistula in methanol, aqueous extract and fresh juice were subjected to phytochemical testing. Results: Chemical testing based phyto-constitutional examination confirmed the presence of flavonoids and saponin, tannin and glycoside, alkaloid in fresh juice, both methanolic extracts and aqueous extract respectively. However, negative results were obtained in case of iodine and trace of glycoside in fresh juice and aqueous extract assured the effect of extracting solvent on chemical composition of plant. Conclusion: The confirmation of phytochemicals in pods of C. fistula gave the positive directions for its medicinal uses that may serve as new therapeutic agent in bacterial infection, constipation, pain and diabetes.
Designing well: Sustain-able Interaction Design and vegetarianism

Designing Well: Vegetarianism Sustainability and Interaction Design, focuses on the field of Interaction Design and is an exploration of how design can be reconsidered by employing a different critical lens – that of vegetarianism. By extending the eating analogy to design, other aspects of practice can be reframed and reviewed. This is done through a survey of different ways designers and artists have approached the problems of electricity use. This survey begins by looking at a number of functional products that are currently on the market, and then turns to consider a range of alternate approaches taken in research, art and critical design. The second half of the paper can be considered as a form of contextual review, as a survey of different approaches artists and designers employ to address a specific issue in and through practice. This ranges from pragmatic design to critical and radical interventions.
Detecting Trending Topic on Chatter.

The amount of posts on social network is overwhelming: for example Twitter has more than 50 millions posts a day. It has become crucial to be able to sort them. By detecting trending topics, which are topics the most discussed on a social network, we allow the user to instantly know what is happening in the network and if he is interesting in one topic, he can get access to all the posts related to this topic. In this work we present and compare different algorithms to detect trending topics. Our approach is to compute similarities between posts and then to find clusters in the graph of similarities using clustering algorithms.
10 Connections between Masculinity, Work, and Career Reproduce Gender Inequality

Gender has been meaningfully tied to relations of production throughout history and across cultural contexts. What this exactly looks like and how it shapes the lived realities of people across time and place, however, has also been and will continue to be subject to great change. This chapter examines four contemporary dimensions of the relationship between masculinity, work, and career as well as how this relationship is connected with systems of gender inequality. We summarise scholarship on (1) the persistence of occupational sex segregation, (2) the effects of the “breadwinner” ideal, (3) the cultural devaluation of femininity, and (4) emergent scholarship on “masculinity contest cultures” at work. Here, we argue that it is through the interconnections between these dimensions that the relationship between masculinity, work, and career contributes to the durability of gender inequality.
Long-Trip Optimization of Charging Strategies for Battery Electric Vehicles

A major drawback of battery electric vehicles is their small range. For long-distance coverage, stops for charging are inevitable. Because of emerging technologies, charging durations can be reduced to 30 min; this reduction means that short stops for charging are possible, even during a long trip. In this study, the problem of finding optimal charging strategies was formulated as a time-dependent, bicriteria, shortest-path problem. The intention was to provide a new feature for navigation by computing for a predefined route when and how long a battery must be charged to reach a destination quickly and reliably (i.e., without the risk of an empty battery). Two algorithms for solving this problem are explained. A case study analyzed the performance of these two algorithms and the impact of several modifications of the underlying graph-based representation of charging possibilities. For practical relevance to be obtained, historical traffic data were used to estimate travel times and energy consumption within the case study, along with real-time traffic information from an online stream hosted by a professional traffic data provider.
Investigation of the inductor’s parasitic capacitance in the high frequency switching of the high voltage cascode GaN HEMT

The concept of the More Electric Aircraft, where the majority of the aircraft’s secondary needs will be supplied by electrical power, is under continuous research over a number of years in order to conform the recent demand for more efficient and environmentally friendly aircrafts. Advancements in power electronics have contributed towards the realization of that demand, by introducing lightweight, high-power density and highly efficient in harsh environment power electronics. The increase in power density of power electronic systems was made feasible, so far, by developments in the semiconductors field, namely by semiconductors that can operate at higher switching frequencies and generate less power loss. Wide-bandgap devices, such as Gallium Nitride (GaN) transistors, have emerged as possible candidates to replace silicon and even silicon carbide devices in various power conversion applications offering potential benefits for high frequency power conversion due to their intrinsic material properties. Another step towards higher power densities is to utilize appropriate circuit topologies since they can reduce the stress upon the components and the cooling requirements. However, as the frequency goes up, the switching behavior of the device is not only influenced by the die itself and the device package’s and circuit’s parasitic elements can not be neglected any more. One of these parasitic elements is the the equivalent parasitic capacitance (EPC) of the magnetic component, which is part of almost every topology. This thesis project aims at two things: first, to observe the switching behavior of a high-voltage cascode GaN High Electron Mobility Transistor (HEMT) under inductive clamped load condition, which is the same commutation mode for the power devices as switching in a PWM, hard-switching type converter and second, to investigate the influence of the magnetic component’s EPC on the switching behavior of the GaN HEMT. For this, an analytical loss model of the device was developed and a double-pulse tester (DPT), which is considered to be a very good example of that load condition, was optimally designed and manufactured in order to verify the analytical model. Two pulses are launched to the device under test (DUT) and the switching transitions of the DUT can be captured for any desired current and voltage rating under hard-switching conditions. Moreover, when operating under that load conditions, applying active devices with reverse recovery charge has significant influence on the switching behavior of the DUT, so both cases will be examined. Finally, in order to characterize the device and eventually verify the analytical loss model, current and voltage measurements need to be taken during the turn-on and turn-off switching transitions. As the GaN HEMT is capable of switching are very high speed, there are issues and limitations that need to be taken into consideration in order to ensure the fidelity and the accuracy of these high frequency measurements
Deterministic methods for sensitivity and uncertainty analysis in large-scale computer models

The fields of sensitivity and uncertainty analysis are dominated by statistical techniques when large-scale modeling codes are being analyzed. This paper reports on the development and availability of two systems, GRESS and ADGEN, that make use of computer calculus compilers to automate the implementation of deterministic sensitivity analysis capability into existing computer models. This automation removes the traditional limitation of deterministic sensitivity methods. The paper describes a deterministic uncertainty analysis method (DUA) that uses derivative information as a basis to propagate parameter probability distributions to obtain result probability distributions. The paper demonstrates the deterministic approach to sensitivity and uncertainty analysis as applied to a sample problem that models the flow of water through a borehole. The sample problem is used as a basis to compare the cumulative distribution function of the flow rate as calculated by the standard statistical methods and the DUA method. The DUA method gives a more accurate result based upon only two model executions compared to fifty executions in the statistical case.
Fuel Efficiency Assessment with DEA

Abstract : In this study, Data Envelopment Analysis (DEA) is used to calculate Air Mobility Command (AMC) airlift fuel efficiency for C-17 aircraft. Fuel is a strategic asset for the United States Air Force and suitable alternatives are not yet feasible or available in the quantity required. The Air Force is pursuing several initiatives to conserve energy and operate more efficiently while sustaining the same level of effectiveness and safety. In order to manage these initiatives, it must measure how well it is doing. To measure airlift efficiency, the AMC Fuel efficiency Office established a 7 factor weighted Fuel Efficiency Index (FEI). To produce a monthly score, AMC assigned weights for each factor. DEA does not require such a prior assumptions and finds the best set of weights that will help each mission to represent itself in the best manner. The results showed that DEA and FEI agree in trends but a DEA Slack-Based Measure better differentiates inefficiencies than other methods used in the study. Also, the results showed that for current Air Mobility flights, at least 10% input excess or output shortfall occurs each month.
General effective medium model for the complex permittivity extraction with an open-ended coaxial probe in presence of a multilayer material under test

The work presented in this thesis is focused on the open-ended coaxial-probe frequency-domain reflectometry technique for complex permittivity measurement at microwave frequencies of dispersive dielectric multilayer materials. An effective dielectric model is introduced and validated to extend the applicability of this technique to multilayer materials in on-line system context. In addition, the thesis presents: 1) a numerical study regarding the imperfectness of the contact at the probe-material interface, 2) a review of the available models and techniques, 3) a new classification of the extraction schemes with guidelines on how they can be used to improve the overall performance of the probe according to the problem requirements.
No rest for the intrapreneur: The case of Switzer rest home

Intrapreneurs are those employees who identify and pursue opportunities in an organisation. As such these employees may influence the strategic direction of the organisation, a process called intrapreneurial strategy-making. In this paper we investigate the nature of intrapreneurial strategy-making, illustrating it with a case in point. In our case the intrapreneur is the manager of a rest home, who needed to find new approaches to work to combat productivity challenges posed by operating in the gerontology sector. We conclude that intrapreneurial strategy-making can be a powerful way to identify and introduce innovation strategies, if driven by a determined manager working incrementally to secure resources and implement change with staff to demonstrate the benefits to them of adopting new work processes.
A self-healing dynamically distributed system for hotel management using JavaSpaces

We present the design and prototype implementation of a low-cost Hotel Management System. In this system, computing devices are distributed throughout the hotel and connected via Ethernet. A number of central processes dynamically create or destroy processes on each computing device as required. Processes communicate either via JavaSpace or directly through the Jini architecture. Redundancy ensures that the system is robust, while Jini Leases ensure that the system is self-healing. Several services needed for Hotel Management are proposed. One major innovation is the use of biometric authentication tools for identification and access controls. The task of matching a given fingerprint to a lists of possible templates is divided by templates in JavaSpace. Another major innovation is the use of mobile Software Agents for scheduling multiple, bundled events. Our prototype has served well as a proof-of-concept, and with further work, we are optimistic that this can become a practical system for Hotel Management.

Cyber Security Threat Intelligence using Data Mining Techniques and Artificial Intelligence

Threat intelligence is the procurement of evidence-based knowledge about current or potential threats. The interest of threat intelligence comprises of advancement in efficiency and boosting effectiveness in terms of analytical and prevention capabilities. Cybersecurity represents serious interest for numerous organizations because maximum of them are using Internet-connected data devices which are opening doors for cyber attackers. Outstanding threat intelligence within the cyber sphere requests for the knowledge base of threat information and a thoughtful way to represent this knowledge. This study proposes a clear rationale of significant artificial intelligence (AI) techniques used for recognizing a cyber-attack. Data analysis can be formulated to guide industries and Internet-connected systems such as smartphones or robotic factories on what to do in the appearance of an incident. AI techniques will analyze past incidents and summarize knowledge from experts and will continue to adapt or reform new branches as it reviews from the new incidents. In addition, various data mining approaches used in boosting threat truthfulness in cybersecurity data are also studied. To conclude, we discussed that; AI will robotize the collation of machine-readable external threats and will improve the efficiency and accuracy of the data for each smart organization’s specific framework.
Kinematic design of a gravity compensated robot for device for ultrasound examination and assessment of endothelial dysfunction.

This paper presents a novel robotic device for the execution of a medical examination for the assessment of cardiovascular risk. The device is a 5 DOFs robot for the accurate positioning of an ultrasound probe for the evalu- ation of the endothelial function. The robot is completely backdrivable, and allows the clinician either to handle the probe directly, like in the traditional medical procedures, or moving it through two rate-control joysticks. The system guarantees a more precise, stable and quick positioning of the probe, improving the reliability of the results and the objectivity of the examination.
Communicating about dredging in a precious environment : Port of Melbourne channel deepening project

The Port of Melbourne is Australia’s largest container and general cargo port, with 37% of Australia’s container trade. By 2035 the Port aims to expand considerably, increasing the number of containers fourfold, and accommodating vessels up to 7,000 twentyfoot equivalent units (TEUs). This expansion plan depends upon deepening the Entrance to Port Phillip Bay. However, in addition to the harbour of Melbourne being a trade gateway and an enormous asset to the national economy, Port Phillip Bay is also a unique social, cultural and recreational asset. It is almost 2000 sq km, with 264 km of coastline and three million people living in its vicinity. It includes two Marine National Parks and a Ramsar wetlands. It is home to multiple fish species, little penguins, whales, dolphins and seals, various coldwater coral species and natural seagrass habitats and is as well an attractive recreational locale for swimming, diving and boating. To achieve this major expansion, the Port of Melbourne sought a relationship with a Contractor of shared responsibility and risk. After thorough vetting, an Alliance Contract was signed in May 2004 between Port of Melbourne Corporation (PoMC) and Boskalis Australia Pty Ltd. Essential specialised equipment required for dredging the Entrance of the Bay was developed. As part of the environmental assessment, key environmental and social values were studied extensively, environmental impacts were evaluated and monitoring programmes were planned. Still as the first dredging ship arrived, she was greeted by protests from some members of the public and by local media. The actual dredging works were consequently delayed until the courts and the public were satisfied that all environmental approvals had been obtained. Not only were extensive scientific research and risk assessments necessary, but also an intensive communications effort from the Contractor and the Port of Melbourne Corporation was needed to inform and educate stakeholders as to what the environmental effects would be and how these were to be managed. The Port and the Contractor spent considerable time, energy and money to demonstrate to the public that the dredging works were not detrimental to environmental, cultural or social assets. Along the way, they learnt several lessons on the importance of transparency during dredging operations.
[Evaluation of susceptibility of multidrug-resistant Pseudomonas aeruginosa strains against ceftolozane/tazobactam].

BACKGROUND Pseudomonas aeruginosa is an opportunistic pathogen associated with high morbidity and mortality. For multidrug-resistant strains (MDR), ceftolozane/tazobactam (CTZ) has been authorized by the European Medicines Agency (EMA) for complicated urinary tract infections, acute pyelonephritis, and complicated intraabdominal infections. AIM To determine the susceptibility to CTZ of P. aeruginosa MDR in isolated clinical samples at the University Hospital Puerto Real. METHODS The susceptibility according to the EUCAST to CTZ criteria of strains of P. aeruginosa MDR, between January 2015 and August 2017 has been studied. The multiresistance criteria were those defined by the Centers for Disease Control and Prevention. The antibiotic susceptibility was obtained by automated MicroScan® system (Beckman Coulter). Susceptibility to CTZ was determined using gradient strips (Liofilchem®, Werfen). RESULTS Of 1253 strains isolated, 7% presented MDR. We studied the susceptibility of a total of 78 strains of MDR P. aeruginosa, of which 5 (6.4%) were resistant to CTZ according to the EUCAST criteria. CONCLUSIONS In our environment, the in vitro resistance to CTZ in MDR P. aeruginosa strains is approximately 6%. CTZ is an option for the treatment of infections by MDR P. aeruginosa when there is no other alternative and its in-vitro susceptibility has been proven.
