INTEGRATION OF HIGH RESOLUTION MODELS IN REAL TIME DECISION SUPPORT SYSTEM, APPLICATION OF AQUAVAR DSS

The groundwater resources often plays significant role of supporting the social development, especially the drinking water supply. Challenged by the global trends such as climate change and growing of urbanization, the harmonization of groundwater in urban system becomes more complicated. The current Decision Support Systems (DSSs) show weaknesses in balancing the environmental sustainability and satisfaction of the stakeholders. The numerical modelling techniques integrated with well spread real-time monitoring system gains more interests by the DSS designers, especially the High Resolution (HR) model simulation. This paper presents one application of integrating high resolution model system in a real time DSS at Var catchment (2,800km 2 ) in the French Mediterranean region. Two HR models of hydrology and groundwater were integrated into one DSS to produce a clear view of the water exchange between surface and shallow aquifers at downstream part of the catchment (last 22km). The developed DSS is currently sued by the local managers with a higher level of satisfaction. The methodology and technical application described here will directly contribute to the future DSS application in any other catchment for different purposes.
GROWTH AND YIELD RESPONSE OF AUTUMN PLANTED MAIZE (ZEA MAYS L.) AND ITS WEEDS TO REDUCED DOSES OF HERBICIDE APPLICATION IN COMBINATION WITH UREA

A field experiment was conducted to assess the growth and yield response of autumn planted maize and its weeds to application of a new post-emergence herbicide Equip (foramsulfuron + isoxadifen-ethyl) alone and in combination with urea. The experiment comprised weedy check, manual weed control, foramsulfuron + isoxadifen-ethyl @ 1125 g a.i. ha -1 alone, foramsulfuron + isoxadifen-ethyl @ 1125, 1012 and 900 g a.i. ha -1 with 3% urea solution. Result revealed that application of full dose of herbicide in combination with urea gives better result than the use of full dose of herbicide alone. Weeds density and total weed dry weight 20, 40 days after spraying (DAS) and at harvest decreased significantly when foramusulfuron + isoxadifen-ethyl along with urea as adjuvant at 1125 g a.i. ha -1 was applied compared to application of herbicide alone at 1125 g a.i. ha - 1 . Full dose of herbicide foramsulfuron + isoxadifen-ethyl at 1125 g a.i. ha -1 alone showed statistically similar results as reducing dose of herbicide foramsulfuron + isoxadifen-ethyl at 1012 g a.i. ha -1 + 3% urea in reducing weeds density, dry weight and increasing yield of maize. The study revealed that the herbicide dose can be reduced up to 10-12% if urea solution was used as adjuvant to obtain the same efficiency as with full dose without compromising on maize yield.
Design of Circularly Polarized Rectangular Patch Antenna with single cut

The focus of this paper is on our contributions towards Single feed circularly polarized antennas. Single feed circularly polarized antennas are currently receiving much attention. Circular polarization is beneficial because current and future commercial and military applications require the additional design freedom of not requiring alignment of the electric field vector at the receiving and transmitting locations. A single feed allows a reduction in the complexity, weight and RF loss of any array feed and is desirable in situations where it is difficult to accommodate dual orthogonal feeds with a power divider network. Circularly polarized micro strip antennas have the additional advantage of small size, weight, suitability in confirm mounting and compatibility with microwave and millimeter wave integrated circuits, and monolithic microwave integrated circuits (MMICS).
Implement of Complex Personal Authentication System applying Biometrics Pattern Algorithm

We propose a complex personal authentication system that enhances user convenience and security to meet the increasing demand for authentication in IOT, wearable devices, mobile services and non-face environments. This system is a complex personal authentication system that can perform authentication processing in real time by combining a biometric authentication method (face, line of sight, fingerprint) and PIN authentication method, which are highly discriminating and difficult to forge and falsify. We also introduced an artificial intelligence processor (Machine Learning) to learn biometric information of the user and increase the accuracy of authentication. This has resulted in a complex personal authentication system that is enhanced against a single authentication algorithm. In future, we intend to develop a more robust and convenient personal authentication system by incorporating deep learning based intelligent system into this system.
The Future of Mobile Information and Communication Technology in Austere Environments: A Command and Control Technology Integration Perspective

Abstract : The information and communications technology (ICT) field is undergoing a period of tremendous and rapid change. As ICT develops more rapidly, the United States Air Force needs to remain responsive and adaptive to maintain military advantages. The need to integrate ICT developments sooner than our adversaries prompted an assessment of guidelines evaluating how well the AF is doctrinally positioned from a Command and Control perspective to support integration of emerging ICT. A Delphi Study was commissioned by the 689th CCW to forecast the future of mobile Information and Communication Technology (ICT) in austere environments. Using the ICT forecast data as a basis, the panel provided inputs on the integration concerns the forecasted trends invoked and the effects of the forecast on the Measures of Effectiveness outlined in AF doctrine.
Impact of developer attitude on software maintenance cost: a descriptive study based on the technology acceptance model

This study examined the impact of the behavioral attitude of software engineers towards software process improvement practices on software maintenance cost. The study used the technology acceptance model to assess the relationship between software developers' attitudes and software maintenance cost. Data was gathered using a 78-item, Web-based questionnaire that measured software attitude, organizational factors, project factors, process maturity and demographic factors. The results are based on self-reported data from 99 software developers and software project managers working in a Fortune 500 corporation, spanning over 20 projects. While the results showed strong relationships between the research model's intervening variables, the findings did not show a significant correlation between software developer's attitude towards software process improvement practices and software maintenance cost. The results show that software developers will adopt and use software process improvement best practices if they perceive them to be useful and easy to use. What is not clear is whether or not developers' attitudes towards usage of software best practices have any impact on developer perceived software maintenance effort (cost).
Prediction Model for Impulsive Noise on Structures

Abstract : A study of impulsive noise propagation and its effect on structures has been performed. Propagation and response measurement were conducted on eleven buildings at three military facilities. Sources included artillery and tank gun firing and explosive ordinance disposal. Propagation measurements demonstrated that the primary path is airborne, not groundborne. Frequency Response Functions were developed for the measured structures, and a general single degree of freedom model for structural velocity response was prepared. A model for Probability of Damage from impulsive noise sources was developed and is presented. That model addresses a wide range of structure types, and provides guidance for impulsive noise criteria in communities.
Development of a Set of Numerical Human Models for Safety

The objective of the European Commission (EC) funded HUMOS2 project is to develop Finite Element (FE) human models representing a large range of the European population and allowing an accurate injury risk prediction for victims involved in road accidents. A human model of a male in a driving position close to the 50th percentile – HUMOS model – resulting from the previous HUMOS project was presented (Robin) at the ESV conference in 2001. The present paper focuses on the new developments that have been made in the still running HUMOS2 project. Firstly, methods allowing the personalization (anthropometry, geometry and position) of human numerical models have been developed. They include a scaling tool enabling to derive any individual model from the original one through mesh control points and statistical relationships between external and internal dimensions. These were established from geometric data collected on standing and sitting human volunteers with a low dose bi-plane X-ray system, but also directly measured on isolated bone parts. A positioning tool has also been developed, based on a set of reference postures including seated car occupant, out of positions (OOPs) and pedestrian postures, in order to adjust and test the models for different sitting and standing postures. Secondly, experimental work has been conducted on human volunteers in order to identify the influence of muscular tensing on body response to moderate impacts. A data base of biomechanical test results, appropriate for model validation, has been set up. It includes new biomaterial laws for ligament and skeletal muscles, as well as existing cadaver test results coming from former EC projects and Heidelberg University. It will be further completed by specific tests performed by consortium members. On-going work includes injury prediction rules introduction in the models, then extensive testing of the model in various conditions defined for validation.
Cocrystals versus Salts of Fluorescein

A series of nitrogen-containing organic molecules (4,4’-bipyridyl; trans-1,2-bis(4-pyridyl)ethylene; 1,2-bis(4-pyridyl)ethane; 4-aminopyridine and trans-1,4-diaminocyclohexane) was envisaged for cocrystallization experiments together with fluorescein. These compounds, containing pyridyl or/and amino nitrogen atoms, can act either as hydrogen bond acceptors for the phenol groups of fluorescein-generating cocrystals or as proton acceptors forming organic salts. Five cocrystals were obtained with the partners containing only pyridyl groups: {(H2Fl)2(bipy)} (1); {(H2Fl)2(bipy)(MeOH)2} (2); {(H2Fl)2(bpete)(EtOH)2} (3); {(H2Fl)(bpete)} (4); {(H2Fl)(bpeta)} (5). The compounds bearing amino groups deprotonate fluorescein producing salts: [(HFl)(Hampy)]∙2H2O (6); [(HFl)(Hampy)] (7); [(Fl)(H2diach)]∙3H2O (8); [(HFl)2(H2diach)]∙2H2O∙EtOH (9); and [(HFl)2(Fl)2(H2diach)3]∙4H2O (10). Optical properties of the cocrystals and salts were investigated.
Left ventricle's surface reconstruction and volume estimation

This document describes the three-dimensional reconstruction of the internal and external surfaces of the human’s left ventricle from actual SPECT data. The reconstruction is a first process fitting in a complete VR application that will serve as an important diagnosis tool for hospitals. Beginning with the surfaces reconstruction, the application will provide volume and interactive real-time manipulation to the model. We focus on speed, precision and smoothness for the final surfaces. As long as heart diseases diagnosis requires experience, time and professional knowledge, simulation is a key-process that enlarges efficiency.
Reorganization of Processes to Gain Competitive Advantages: The Case of Rail 2000 and Beyond

For successful competition in public passenger transport the offer in transport opportunities and its quality play an important role. The processes to define the service including the necessary infrastructure as well as to produce the train slots are key elements for success in the market. The RAIL 2000 concept in Switzerland is a successful example for the definition process. SBB’s new approach for the track slot production process will bring a higher quality of the offer and additional capacity with minimal investment. These two different processes and described and the anticipated effects are documented.
Assessment of pelA-carried Pseudomonas aeruginosa isolates in respect to biofilm formation

Owing to high antibacterial resistance of Pseudomonas aeruginosa, it could be considered as the main reason behind the nosocomial infections. P. aeruginosa has a well-known biofilm forming ability. The expression of polysaccharide encoding locus (pelA gene) by P. aeruginosa is essential for this ability. The purpose of the current research was to determine the biofilm formation in P. aeruginosa isolated from clinical samples and to evaluate the role of the selected PelA gene in biofilm formation using PCR method in Iraqi patients. Results revealed that 24 (96%) isolates were found to have the ability to form biofilm that was remarkably related to gentamicin resistance. Moreover, the pelA gene was found in all biofilm-producers. In conclusion, the results of the current study revealed that the P. aeruginosa biofilm-producer isolates were resistant to the antibiotics in question. Likewise, because of wide spreading, it appears that the pelA gene is related to biofilm formation.
Operationally Intuitive Logistics Dashboards for Supply Chain Management in Oil and Gas Based on Human Cognition

Due to globalization over the past two decades, the importance for companies to have appropriate supply chain management (SCM) has intensified substantially. The real-time connectedness and sharing of data has created a unique opportunity to design software programs for the purpose of improving elements of operations in the supply chain (SC), both upstream and downstream. As a result of these progresses, dashboards have been designed to facilitate transparency, with the purpose of providing a better overview of a specific operation. We argue there is room for improvement within the field of dashboards for decision making by making the user and their experience the core of the dashboard design and tapping into the cognition processing of the brain to optimize the user friendliness.
ARTICLES: Generation of ultrashort pulses in a negative-feedback laser

The results are given of theoretical and experimental investigations of stimulated emission from a modelocked negative-feedback solid-state (ruby) laser. Under certain conditions, governed by the delay time in the feedback circuit, the laser suffers from high-frequency instabilities in the form of sehvlocked intermode beats. These instabilities increase significantly the stringency of the requirements which have to be satisfied if negative feedback is to be used for amplitude stabilization.
The Contribution of Gamification to Self-Managing Team Performance

Two gamification designs are developed and used during two gamified interventions with self-managing teams at ING Operational Services. These interventions are conducted for with two self-managing teams for 2 and 4 full weeks. The reserach included Interviews, brainstorm sessions, questionnaires, focus groups and de-briefIng meetings. The development of both a working gamification system and a theoretical framework of gamification for self-managing team was within the scope of this research project.
Investigating Math Self-Efficacy and Math Anxiety Regarding Gender, A-Level Math Entry Grade and Mathematics Achievement

Although mathematics is perceived as an indispensable pre-cursor to success in modern society, many students still grapple with a genuine fear of mathematics and feel anxious when engaging in mathematical tasks. One of the affective factors that can affect math anxiety is learners’ belief in their own ability which is termed self-efficacy. In this study we aimed to investigate how math anxiety and math self-efficacy varied across gender, A-level math entry grade and recent mathematics score and how math anxiety and math self-efficacy related in the context of students in Mayuge District, Uganda. We collected data from 60 advanced level (A-level) mathematics students from two secondary schools in Mayuge District. Their study of mathematics was not compulsory but rather by choice. The participants filled a Mathematics Self-Efficacy and Anxiety Questionnaire (MSEAQ). Data were analyzed using descriptive statistics, independent sample t tests, one-way ANOVA, Pearson’s Linear Correlation Coefficient (PLCC) and linear regression. Descriptive statistics indicated a high level of math self-efficacy and a low level of math anxiety among the students. Independent sample t tests revealed no gender differences in math self-efficacy and math anxiety and ANOVA suggested no differences in math self-efficacy and math anxiety for the A-level math entry grades and recent mathematics scores. PLCC revealed a strong significant negative linear correlation between math self-efficacy and math anxiety with r = -0.782. Meanwhile, regression analysis suggested that math self-efficacy explained 60% of math anxiety among A-level students in Mayuge District. A recommendation was made.
Improvement of the management of anticoagulation in Atrial Fibrillation patients in the emergency and acute medical departments; a service quality improvement report

Atrial fibrillation (AF) is considered one of the main causes of ischemic stroke. The CHA2DS2VASC score can predict the stroke risk. Proper anticoagulation can significantly reduce such risk. Anticoagulation involves a risk of bleeding, which can be predicted by the HAS-BLED score. The non-documentation of both AF risk scores in the medical notes of patients presenting with acute or paroxysmal AF has alerted our team, for fear of missing administering the proper anticoagulation. A baseline audit showed that the CHA2DS2VASC score was documented in 27% of such patients, while the HAS-BLED score was documented in 5% of them. A quality improvement project was planned and included two PDSA cycles over a period of five months. The first cycle was based on raising the awareness of the junior doctors on risk assessment of AF patients and the importance of anticoagulation prescription. This involved educational posters, emails, and presentations. On the second cycle, the baseline audit showed a 69% improvement (from 27% to 46%) in the rate of CHA2DS2VASC score assessment and a 140% improvement (from 5% to 12%) in the rate of HAS-BLED scoring. However, the rate of anticoagulation prescription remained almost the same in both cycles (55% and 52%). A doctors’ survey showed that they are not quite comfortable prescribing long-term anticoagulation on acute care units because of the inadequate assessment of the bleeding risk, and the associated comorbidities that can disturb the action of the oral anticoagulants. They preferred to refer the patient to a specialised AF clinic for further assessment and prescription. On auditing the patient referral on discharge, it was found that 91% of the patient were seen at the AF clinic in 2 weeks. The remainders were referred to their GP for further assessment and prescription. That seemed to be a safer way of anticoagulation prescription for such patients.
Effect of Palm Cooling with Negative Pressure on Heat Balance During Exercise in a Hot, Dry Environment

Abstract : Military personnel often must work in hot environments, increasing the risk of hyperthermia. Our purpose was to evaluate a new rapid thermal exchange device (RTX) in slowing the development of hyperthermia and associated symptoms to 3 other conditions [hand immersed in water bath (WB), water-perfused vest (VEST), and a no- cooling condition (NC)] in subjects exercising in a hot environment (42C, 30% rh) wearing summer fatigues, a backpack and body armor. Ten subjects (age 25+/-3 yrs; weight 74+/-6 kg) performed 4 heat stress tests in a counter-balanced order (NC/RTX/WB/ VEST) The protocol consisted of two bouts of treadmill walking (at 50% VO2max), separated by a 41-min cooling and rehydration period. The time to reach a pre-determined rectal temperature (Tr) in the 1st and 2nd bouts were not different among RTX (mean +/- SD; 52+/-14 and 42+/-l2 min respectively), NC (49+/-13 and 4l+/-14 min respectively), and WB (54+/-14 and 55+/-20 min respectively), but was longer for the VEST (85+/-30 and 65+/-12 min respectively) in both bouts (p<0.05). The Trslope (C/min) was significantly lower for VEST in the 1st and 2nd bouts versus the other conditions (p<0.05). HR was not different at 10,20 and 30 minutes of exercise in the 1st bout among RTC, NC, and WB, but was lower for VEST in the 1st bout (p<0.05). HR was not different among conditions in the 2nd bout. Therefore, the RTX (unit B) was not effective in slowing the development of hyperthermia in the present protocol. Aspects related to hand vasoconstriction and the severe work/heat stress conditions possibly prevented the expected heat extraction.
Experimental Study of Breaking Wave Flow Field Past a Submerged Hydrofoil By LDV

In the present work the free surface flow past a submerged hydrofoil was studied by experimental techniques. The purpose of this experiment, carried out in a water circulating channel, was to examine the flow field concerned with the steady 2-D breaking wave. Free surface profiles were measured by a conventional wave probe, whereas the velocity field was obtained by LDV, both in non-breaking and breaking conditions. Experimental data are discussed in comparison with simple numerical solutions as well as some results available in the literature.
THE ROLE OF LEARNER VARIABLES, TOOL VARIABLES AND INTERVENTIONS ON TOOL USE AND PERFORMANCE IN COMPUTER LEARNING ENVIRONMENTS

The current study investigates the effects of cognitive (prior knowledge) metacognitive (perceptions) and motivational (self-efficacy) learner variables, tool presentation (non-/embedded tool), and tool interventions (explanation of tool functionality) on quantity and quality of tool use. Additionally, the effects of quantity (time and frequency) and quality of tool use on performance. One hundred and seventeen university students were randomly assigned to one of five conditions (Embedded and nonembedded with explained tool functionality, embedded and non-embedded with non-explained tool functionality and one control condition) to study a hypertext. Results reveal, first, that there was no significant difference among conditions in performance. Second, prior knowledge had a positive effect on frequency of tool use, perceived tool usability had a positive relationship on time spent on tools and self-efficacy showed no significant effects on tool use. Third, tool presentation (embedded or nonembedded) had no significant impact on the use of tools. The explanation of the tools functionality showed, on the other hand, a negative impact on quantity of tool use (time). Finally, only time spent on tools had a positive relationship with performance. Unexpectedly, quality of tool use and frequency of tool use were correlated and the latter had a negative impact on performance. Theoretical implications are discussed.
