Introducing information systems students to research with a structured group project

This chapter reports on an approach to getting information systems research students started. The approach involves beginning research students undertaking a structured group research project in which the instructor is an active participant. The major purpose of this group project is to provide a gentle, supportive, structured introduction to information systems research. This approach benefits students by ensuring that they have participated in a complete research project before they have to assume complete responsibility for their first large individual project. The chapter discusses the use of this approach at an Australian university. In general, students have participated well, learning from their own experiences and the experiences of others in the group.
A discrete choice study to assess the impact of reliability on passenger rail demand

A study is described of the impact of punctuality (i.e. where a train runs to time) and reliability (i.e. whether a train runs at all) on passengerrail demand, funded by the UK Department for Transport. This study aspires to place emphasis on actual (i.e. revealed and reported) behaviour, and to obtain direct estimates of the effects of changes in travel time variability on rail demand. Econometric analysis of rail ticket sales data has made a major contribution to understanding rail demand, and there is no reason in principle why this method cannot also yield insights into the demand impacts of train punctuality and reliability. Naturally, any such analysis might yield particular insights when applied to routes and periods thathave been subject to travel time variability. Acknowledging this, a meeting was convened with industry representatives for purposes of identifying potential study contexts. Guided by this consultation, a sample of 240 origin-destination pairs (480 single flows) on a 13-period basis from 1996 until the present was developed to form the basis for an econometric analysis. This analysis is supported by data from various sources; principally LENNON ticket sales data, generalised journey times from MOIRA and performance data directly from train operating companies (TOCs); and will exploit panel data methods. Whilst the econometric analysis is couched in terms of some notion of the aggregate, disaggregate analysis permits more detailed consideration of the agents that comprise the market. In the present case,disaggregate analysis offers a means of revealing travellers' attitudes to risk and monetary valuations of punctuality and reliability. It was decided at the outset of the project that disaggregate analysis might usefullycombine three elements: retrospective questioning, revealed preference (RP), and stated preference (SP). A passenger questionnaire appealing to both characteristics was produced. In order to mitigate the risks of relying entirely on revealed and reported preferences, a final component of the questionnaire was SP. The analysis of the data is described.

This paper reviews this class of problems that is characterized by the interaction between location and routing decisions. The main examples and applications found in the literature are described. Mathematical models as well as heuristic and exact algorithms for their solution are then presented. (Author/TRRL)
Numerical Studies for a Single Pass High Gain Free-Electron Laser

The importance of single pass high gain Free-Electron Lasers (FEL) is due to its the unique characteristic of the short, high intense radiation pulse at a well defined, tunable frequency. Extending the radiation wavelength to the ultraviolet or X-ray region is an on-going research project and will open new branches of experiments based on this radiation. Several projects are proposed or currently under construction such as the integrated X-ray FEL at the TESLA linear collider and the VUV FEL at the TESLA Test Facility. For all of these projects a detailed study is of importance, including all effects which might influence the FEL performance. In particular, for an FEL operating at X-ray wavelengths, the amplification process is more sensitive to any kind of disturbance. Some of these perturbations influence the FEL performance in a complex way. Because existing codes are not capable to cover these problems the simulation code GENESIS 1.3 has been developed. The new features of GENESIS 1.3 includes the discretization of the radiation field on a Cartesian grid and the input of arbitrary profiles of the undulator field and the electron beam in longitudinal direction. The code is capable of covering aspects such as beam halos, wake fields and non-periodic focusing structures to name a few. Using GENESIS 1.3 special aspects of the TTF-FEL and TESLA FEL have been studied. The simulation covers the transverse motion of the electron beam, the impact of wake fields as well as the increase of the energy spread due to the quantum fluctuation of the incoherently emitted radiation.
Carbon materials prepared from cigarette filters APPLIED for clofibric acid adorption

Chars and carbon membranes were prepared from fresh and smoked cigarette filters, and used as adsorbents for clofibric acid removal. Carbonization of cigarette filters took place at 650, 750 and 900 °C, whereas membranes were synthesized by filter dissolution in acetone, using NaCl (porogen) and glycerol (plasticizer). Acid mediated carbonization (225 and 250 °C) of the membranes was performed. Solution pH was monitored throughout the adsorption experiments. The chars are basic powders with apparent surface areas up to 494 m 2 g -1 and a porosity composed by supermicropores (0.7-2 nm wide) and mesopores (2-50 nm wide), allowing clofibric acid (critical dimension 0.6 nm) to access all adsorption sites. Carbonization of smoked filters promoted higher porosity levels and SEM analysis showed that a more extensive carbonization occurred in the outer surface of the chars particles. The presence of TiO 2 particles was confirmed in all the chars. Pores were homogeneously created at the membranes surface. Acidic carbon membranes (pH PZC ≈ 3.7) were obtained with different degrees of porosity, proportional to the pyrolysis temperature. Both forms of clofibric acid (protonated and deprotonated) were readily adsorbed onto the carbon materials, with exception of the chars prepared at 900 °C, which adsorbed predominantly the deprotonated form. In equilibrium, an inverse correlation between solution pH and concentration of the pollutant was observed, and higher uptakes were observed for experiments with solution pH values above 5, suggesting that adsorption of the neutral species contributed significantly to the overall removal.
SARA: Tool to Assess and Improve Functional Resilience from Security Attacks of Passenger Intermodal Stations and Terminals

Considering the rapid growth in urban population around the world, connectivity and accessibility become crucial factors for development and public transit systems, likely the preferred mobility options in densely built and populated areas. In the light of their growing significance, public transport stations and terminals are starting to be designed as complex intermodal interchanges through enhanced interconnection between transport systems. All these facilities attract large numbers of people and most of them need to remain open to the general public. The station itself needs to remain highly permeable, as its main function is to ensure the good operation of transport facilities and unobstructed passenger flows. Due to the combination of large infrastructure value and concentration of human lives, stations and their environment are plausible potential terrorist targets. Under these premises, this paper is dedicated to the description of a systematic framework to support station designer to evaluate the vulnerability and availability of the station equipment. The framework would ideally enable the station functional resilience assessment, looking at individual equipment, the effects of their loss of functioning, the definition, evaluation, ranking and selection of countermeasures to reduce risk of terrorist attack, under economic and financial constraints. The framework has then been implemented in a tool called SARA (SECURESTATION Attack Resilience Assessment), which is herewith described. The whole work has been developed in a EU funded research project called SECURESTATION, financed by the European Commission under the umbrella of the 7th Framework Programme.
GENETIC AND GENOMIC PROSPECTS FOR CAMEL MEAT PRODUCTION

Camelids, originating in the Eocene Epoch, have diversified and the modern dromedary occurred during the Holocene in the Arabian Peninsula where it was subsequently domesticated. It provides meat, milk and other products, and Pakistan ranks ninth in the world in terms of camel population. It is well adapted to an arid environment and has a huge potential for food and economic security in the context of climate change, particularly via a genetic improvement for meat production. This article reviews the current knowledge on camel genetics, in relation to genetic improvement. It considers genetic diversity to understand breed differences and their historical origins, using molecular markers, as well as identification of sites of genetic polymorphisms in the camel genome, essential tools for genetic study. Several methods useful for genetic improvement in the camel are considered, including use of candidate genes such as GH, IGF1, GHR likely to affect camel growth. The use of marker assisted selection (MAS) as well as modern methods including genome-wide association studies (GWAS) and genomic selection also been reviewed. Using genetic and other modern technologies, modern farming systems for camels can be introduced making a significant contribution to the rural economy.
Airworthiness and Flight Characteristics Test (A&FC) of the CH-47D helicopter

Abstract : An Airworthiness and Flight Characteristics Test of the Boeing Vertol CH-47D helicopter (USA S/N 81-23383) was conducted by the U.S. Army Aviation Engineering Flight Activity. The test was conducted at St. Paul, Minnesota (elevation 704 feet). Edwards Air Force Base (elevation 2302 feet), Bishop (elevation 4120 feet), and Coyote Flats (elevation 9980 feet), California. A total of 148.8 hours (105.4 productive hours) were flown between 25 January and 13 December 1983. Hover, level flight, and autorotational descent performance tests were conducted. Handling qualities tests included static and dynamic stability, maneuvering stability, takeoff and landing characteristics, power management, simulated systems failures, simulated Instrument Meteorological Conditions flight evaluation, and vibration evaluation. Cockpit and subsystem evaluations were also made. The CH-47D exceeded those performance requirements of the Prime Item Development Specification which were evaluated during this test. The Advanced Flight Control System heading select capability and the pressure refueling capability were found to be enhancing characteristics of the aircraft. Three significant shortcomings were found: the poor engine governing system which allows large rotor speed excursions with changes in power setting or airspeed, the high level of cockpit vibrations at and above cruise airspeeds, and an easily excited three-axis airframe oscillation during high power conditions at light gross weight.
Power output at different loads using accommodating resistance in the bench press exercise

Introduction: To date, there are no definitive guidelines as for how to optimally train for power production. Previously conducted studies are lacking consensus and have reported conflicting suggestions regarding what loads to use and how to execute the movements. Finding an optimal method of training for power would be beneficial for power and strength athletes. Accommodating resistance has been suggested as an effective method for developing power in athletes. Aim: This study examined how using different amounts of accommodating resistance influence peak power output in the bench press exercise. Method: Fourteen subjects tested their 1 repetition maximum (1RM) in the bench press and after seven days performed a power test consisting of three repetitions with 30,40,50,60 and 70% of 1RM and peak power was recorded using the MuscleLab linear encoder. A second power test was done seven days later, where the load at which the highest power was demonstrated was used again and different amounts of that bar weight was replaced with band resistance. The proportions used were 20:80, 30:70, 40:60 and 50:50 band tension to bar weight. Three repetitions were performed at each of the band conditions and peak power was recorded. The highest value for each trial was used for analysis. Results: The average load at which the highest power (553,49±111,62W) was produced was 46,46kg (43,85±7,68% of 1RM). All of the band conditions except for the 20:80 demonstrated a significant difference in power output compared to bar weight only. The 50:50 proportions of band tension to bar weight resulted in the highest power (813,31±252,87W) of the band conditions. Conclusion: These findings indicate that the use of accommodating resistance results in higher power output than using bar weight only when the total load is constant. Higher proportions of band tension seem to result in higher power output compared to lower proportions. These results could offer guidelines for how to design optimal power training for athletes.

Design of Substrate Integerated Waveguide Bandpass Filter Based on Metamaterials CSRRs

This article presents a band-pass Substrate Integrated Waveguide (SIW) filter based on Complementary Split Ring Resonators (CSRRs). By etching Square Complimentary Split Ring Resonators on the surface of the substrate integrated waveguide. The bandpass filter is treated by two methods. The first method concerns the use of three square single ring CSRRs cells are etched in the top plane of the SIW, the simulated results of this filter have shown that the passband is from 7.267 GHz to 9.933 GHz, while the insertion loss is -1.11 dB within 31% bandwidth around 8.6 GHz and input return loss in the passband is better than -8.91 dB. The second method concerns the use of three square double rings CSRRs cells are etched on the top plane of the SIW, the simulated results of this filter have shown that the passband is from 7.34 GHz to 9 GHz, while the insertion loss is -0.47 dB within 20.31% bandwidth around 8.17 GHz and the return loss in the passband is better than -15 dB. All the structures are designed on a single substrate of RT / Duroid 5880 permittivity 2.2. The compatibility with planar circuits is provided via a specific microstrip transition (microstrip tapered transitions).
From Essential Use Cases to Objects

One of the main motivations for essential use cases was the context of user interface design. We, however, have been exploring the application of essential use cases in general object-oriented system development. Our experience has been ve ry positive, and we found advantages to essential use cases that assist in both analysis and in design. This paper outlines two techniques involving essential use cases: use of role -play in requirements analysis, and distribution of system requirements fro m essential use cases to objects. [
Análisis de los discursos de médicos vertidos en Twitter sobre la validez de posibles tratamientos contra la COVID-19 / Discourse analysis of physicians on Twitter about the validity of possible treatments for COVID-19

Introduction: Twitter is a platform that prioritizes the immediacy of communication; nevertheless, tweets in scientific areas rarely reach a wide audience. Objective: To examine discursive strategies used by Peruvian doctors with an active Twitter account on the validity of possible treatments for COVID19. Methodology: Critical discourse analysis - using Fairclough's three-dimensional model - with the help of notions of ethos. Results: Two areas were found where the medical-scientific discursive ethos is expressed: the construction as individual specialists in health and the approach given to the aspects of the medical-scientific ethos: the method, the evidence and the pseudo-scientific. Conclusions: The language used in the tweets is impersonal and neutral. The positioning of individuals as health specialists is through a thematic opinion. A discursive ethos that reinforces the existing pre-discursive ethos through discursive strategies such as denomination and intertextuality develops this positioning.
MOSFET Models for VLSI Circuit Simulation: Theory and Practice

This study discusses MOS transistor models and their parameters required for VLSI simulation of MOS-integrated circuits. It gives detailed presentation of model parameter determination for MOS models. Various models are developed ranging from simple to more sophisticated models that take into account new physical effects observed in submicron devices used in today's MOS VLSI technology. The assumptions used to arrive at the models are emphasized so that the accuracy of the model in describing the device characteristics are clearly understood. Understanding these models is essential when designing circuits for the state-of-the-art MOS ICs. Since threshold voltage is the single-most important MOSFET parameter, a full chapter is devoted to the development of the device threshold voltage model. Due to the importance of designing reliable circuits, the device reliability models, as applied for circuit simulations, are also covered. Since the device parameters vary due to inherent processing variations, how to arrive at worst-case design parameters are also covered. Presentation of the material is such that even an undergraduate student, not well familiar with semiconductor device physics, can understand the intricacies of MOSFET modeling. The book serves as a technical source in the area of MOSFET modeling for state-of-the-art MOSFET technology for both practicing device and circuit engineers, and engineering students interested in the area.
Development and Validation of a Hybrid-Computer Simulator for a Transonic Cryogenic Wind Tunnel

SUMMARY Experience during the past 6 years of operation of the Langley 0.3-Meter Transonic Cryogenic Tunnel has shown that there are problems associated with the operation and control of such tunnels. One problem has been an inability to provide long-term accurate control of test parameters. Additionally, the time required for transition from one test condition to another has proven to be excessively long. Due to the high degree of process cross-coupling between the independent control variables, man-in-the-loop operation has proven to be much less efficient than desirable in terms of liquid-nitrogen and electrical- power usage. For these reasons, studies have been undertaken at the Langley Research Center to model the cryogenic-wind-tunnel process, to validate the model by the use of experimental data, and to construct an interactive tunnel simulator with the validated model. Additionally, this model has been used

A Behavioral Design to Reform Italy’s Evaluation Policy

Drawing on the extensive ethnographic research I conducted on Italy’s performance evaluation system, this article highlights the cognitive biases associated with evidence use in decision making and institution working. Framing effects, status quo bias, motivated reasoning, and tacit conflicts between personal and organizational interests were only some of the behavioral phenomena policy makers, managers, and evaluators showed to limit their exposure to performance information. Integrating behavioral findings with theories of governance, evaluation utilization, and critical evidence–informed policymaking, this article discusses behavioral reform strategies to overcome (i) tacit conflicts of interests among evaluators, (ii) the compliance mentality with performance assessment among managers, and (iii) adversarial relationships between courts and administrative agencies as well as polarized politics with respect to evidence use and experts’ behavior. A behavioral design is relevant to reform evaluation policies, especially in countries where performance regimes have been criticized, contested, resisted, and/or perceived as red tape and surveillance mechanisms.
