Mobile eyetracking for decision analysis at the point-of-sale: Requirements from the perspectives of marketing research and human-computer interaction

In a typical grocery-shopping trip consumers are overwhelmed not only by the number of products and brands in the store, but also by other possible distractions like advertisements, other consumers or smartphones. In this environment, attention is the key source for investigating the decision processes of customers. Recent mobile eyetracking systems have opened the gate to a better understanding of instore attention. We present perspectives from the two disciplines marketing research and human-computer interaction and refine methodical and technological requirements for attention analysis at the point-of-sale (POS).
In- Vitro Study of Antibacterial Properties and Phytochemical Contents of Coriander Seeds Against Five Bacteria.

In an effort to highlight the role of digestion and maceration methods to determine the strength of antibacterial effect and phytochemical elements of coriander seeds aqueous and methanolic extracts. Five concentrations (20, 40, 80, 160 and 320 mg/ml) of four extracts (aqueous by maceration, aqueous by digestion, methanolic by maceration and methanolic by digestion) were utilized against five clinically isolated bacteria (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aerogenosa and Acenitobacter baumani), and compared with ciprofloxacin and cefotaxime discs as control. Agar well diffusion technique was employed to clarify the antibacterial activity of the extracts' concentrations relaying on quantifying the diameter of inhibition zone (IZ) in millimeter. The bioactive chemical compounds of four extracts were specified by means of conventional systems. In the main, all extracts inhibited the growth of every bacterial species starting from (80) mg/ml concentration, forming IZs' with various measurements that their expansion was drawing upon the rising of extracts' concentrations. The IZs that proceeded from (160, 320) mg/ml concentrations were larger than that come out from cefotaxime. The maceration extracts declared their embracement of alkaloids, and their impact were vigorous compared with the extracts of digestion which marked by comprising the tannins and flavonoids in aqueous and methanolic extracts one by one. The most susceptible bacterium to ethanolic extracts was S. aureus. It could be benefiting from coriander seeds for treatment of bacterial infections through extraction the Kirkuk University Journal /Scientific Studies (KUJSS) Volume 14, Issue 2, June 2019 , pp. (1-18) ISSN: 1992-0849 (Print), 2616-6801 (Online) Web Site: www.uokirkuk.edu.iq/kujss E. mail: kujss@uokirkuk.edu.iq, kujss.journal@gmail.com 2 best active phytoconstituents by using both of suitable extraction technique and solvents together.
OPTIMIZATION OF TRAFFIC SIGNAL TIMINGS FOR USER EQUILIBRIUM

A bi-level programming approach has been used to tackle traffic signal timings optimization problem subject to user equilibrium flow, in which the optimization for signal settings with respect to the common cycle time, and the states and durations of green was dealt with as the upper level problem whilst a user equilibrium traffic assignment was dealt with as the lower level problem. A sensitivity analysis method was used and the derivatives for the performance index have been derived and used. The mixed search procedure was proposed to solve the bi-level formulation. The gradient projection method was used in deciding the optimal step length. Aalsop and Charlesworth's aging results showed the robustness and effectiveness of the method as values of the performance index were improved further in comparison with other conventional methods.
DEVELOPMENT AND APPLICATION OF A SHIP MANOEUVRING DIGITAL SIMULATOR FOR RESTRICTED WATERS

Abstract This paper reports on two case studies making use of a digital simulator to investigate the manoeuvring motions of ships in canals with shallow and restricted waters. The first case study corresponds to a manoeuvring analysis conducted for the Port of Rio Grande (RS – Brazil), whose aim was to assess the potential impact upon manoeuvres of the presence of a large offshore platform (the Petrobras P-53) which is to remain docked for several months at the Port to complete its construction. The second study made use of the simulator to evaluate the manoeuvring conditions along the approach route and manoeuvring basin of the Port of Ponta do Felix (PR – Brazil). The simulator includes a complete mathematical model of the ship dynamics in the horizontal plane when subjected to wind and current forces. It also comprises detailed models for the action of thrusters and propellers, both fixed and azimuth, employed to control manoeuvres and dynamically position ships, as well as rudders and tugboats. The models used by the simulator allow for the effects of shallow and restricted waters, including the increase in resistance and lateral forces, increase in additional mass and the appearance of lateral and vertical suction (squatting). The simulator is implemented via an interactive interface through which the user is able to apply control actions (rudder angle, main engine, thrusters and tugboats) in real time during manoeuvres, thereby reproducing to some extent the action of a pilot.
Software process improvement in a medium-sized company

For many organisations, software is a crucial component of their business as it provides a competitive advantage over other organisations. Hence, they are very keen to ensure that the software they employ is not only reliable and defect-free, but also cost-effective to produce and maintain. That is, organisations desire the highest quality of software, but at a minimum cost and time. Research into software engineering has shown that by improving software development or maintenance processes, there can be an improvement to the software quality. This thesis describes how software process improvement has been implemented in a medium-sized company where software is used to automate manufacturing processes. Prior to this study, there had not been any form of software process improvement in the company, although they followed company standards and procedures that have been in place for over a decade. The aim of this study is to use software development and maintenance projects in the company as cases for process improvement initiatives. Each case provides evidence in support of a hypothesis that is associated with it. For each case study, the problem is assessed, a diagnosis has been researched and actions have been taken based on that research. Each hypothesis is evaluated at the end of the thesis followed by conclusions of the whole research. The principle outcome of this research is that software practices of a medium-sized company can be improved using small-scale software process improvement. Using the CMM as a guide, software process initiatives were implemented to address specific areas of software engineering, i.e. maintenance, testing, planning and control, requirements management, and testing. Efforts have been made to raise the company's maturity in the CMM with respect to these areas. Collectively, the case studies achieve improvement of software practices by way of applying software process improvement in a systematic manner - in this case the IDEAL framework from the CMM.
Progress in Carbon Nanotube-Based Electrochemical Biosensors – A Review

The use of carbon nanotubes (CNT) for fabrication of sensors and biosensors has increased considerably over the past decade. This review covers the progress and advances made during the years (2014-2018) in the utilisation of carbon nanotubes for fabrication of electrochemical biosensors. The focus of the review is on reported CNT-based biosensors for detection of, important substances, such as glucose, H2O2, (DNA), ascorbic acid, uric acid, dopamine, metal ions, and pesticides. The review starts by first discussing the structures and properties of CNTs, followed by discussion of some of the synthetic methods for CNTs preparation. The working principles and performances of CNT-based biosensors are then discussed. Considerations for future developments in CNT-based biosensors are also outlined.
Alternatives to 3He for Neutron Detection for Homeland Security

Neutron detection is an essential aspect of interdiction of radiological threats for national security purposes, since plutonium, a material used for nuclear weapons, is a significant source of fission neutrons. Radiation portal monitoring systems, of which there are thousands deployed for homeland security and non-proliferation purposes, currently use 3He gas-filled proportional counters for detecting neutrons. Because of the high usage of 3He for neutron scattering science and national security, the supply has dwindled, and can no longer meet the demand. Consequently, a replacement technology for neutron detection is required in the very near future.
Virtual methodology for predicting whistling noise over the front grill of a vehicle

This research presents an approach in predicting the presence of a noise source generated by the external flow around a fin-like member of a vehicle front grill. The goal was to determine if a low-resource computational method could be used to capture the pressure fluctuations related to the noise frequencies audible during experimental evaluations on the geometry. Two nearly identical profiles were studied where would generate wind noise in the presence of high velocity flow and the other would not. Several simulations were run on both shapes in four arrangements using incompressible and compressible solvers in attempts to determine an accurate and efficient way in capturing the phenomenon. Results have shown that incompressible cases will only capture the pressure fluctuations of shedding vortices and that a compressible simulation of multiple profiles arranged similar to the construction of the actual grill component generates results closest to those of the experiments.
Ornamentals: Where Diversity is King—the Israeli Experience

In the increasingly competitive international cut flower and pot-plant market, novelty of crops plays an important role in maintaining and expanding market share. The ornamental industry is unique among the agricultural industries in that novelty is an important attribute. Customers always seek “something new. ” Although the standard major ornamental crops will continue to constitute an important part of the market, a distinct trend towards increasing the share of “new crops” is clearly evident in recent years. These new products normally fetch higher prices than the traditional crops for a certain period, but quite often the prices drop when the market is saturated, and the attraction novelty lessens. By that time new products should be ready to enter the market. Research on introduction of new ornamental crops is therefore an endless project. The floriculture industry in Israel is relatively new. Until about 30 years ago cut flowers and potplants were only produced on low-scale for the limited domestic market. In recent years ornamental plants became a major agricultural exportable product of over 250 million US$ per annum. Israel is now second only to Holland in flower export in Europe. Initially Israel produced and exported mainly the major traditional cut flowers, such as carnations, roses, and gladiolus. Gradually the share of these crops declined and those of new minor crops increased, so that the “new crops” now constitute over 60% of the exportable cut flowers (Fig. 1). None of these “new crops” has become a major crop as roses or carnations, but together they are and will certainly continue to be the major part of our exportable ornamental products. Introduction of new crops includes many research stages that begins with the initial search and screening and is concluded when the product is introduced commercially. The introduction and adaptation of new exportable crops normally includes the following stages: 1. Searching for optional crops. 2. Selection and improvement. 3. Developing propagation methods. 4. Studying the growth and flowering physiology and developing practical means for their control. 5. Evaluation of horticultural practices. 6. Studying postharvest physiology and developing practical methods for postharvest handling, transport, and storage. 7. Semi-commercial export shipments to markets abroad. Some important cut flowers (in European markets), which we introduced and developed in Israel, were “new crops” about 25 years ago such as Gypsophila and Geraldton wax flower. The development of these and other crops are described in the following examples of successful introduction projects.
Heat Transfer Augmentation through Different Jet Impingement Techniques: A State-of-the-Art Review

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.
Regional extreme rainfall estimation in Middle Black Sea Region, Turkey

The occurrence probabilities of heavy rainfalls brought about flood events have an essential role in designing water-related structures and water resource management. In many cases, data for analysis are either not available or are insufficient for reliable design of water-related structures. Regional frequency analysis is frequently preferred to provide design information at sites with especially inadequate data available. Our study implemented L-moment procedures to annual maximum rainfall series from 70 gauging stations in the Middle Black Sea Region (MBSR) in Turkey to estimate regional rainfall quantiles. The first attempt for regionalization was to evaluate the entire area as an only homogeneous region. The sub-regions were initially defined with the ward’s clustering algorithm due to the presence of discordant sites under a presumption of a single homogeneous region. In compliance with the results of the discordancy and heterogeneity measures, the most promising classification was achieved with 6 clusters (sub-regions). The sub-regions have satisfied the homogeneity condition as “acceptably homogeneous. ” The GEV and GLO distributions in five sub-regions, GNO distribution in four sub-regions, and PE3 distribution in three sub-regions were decided to be acceptable as a regional frequency distribution. In comparison, GPA is a candidate distribution in none of six sub-regions.
An Approach for Mitigating Denial of Service Attack

Distributed Denial of Service (DDoS) attacks are the most common types of cyber-attack on the internet and are rapidly increasing. Denial of service/distributed denial of service attack is an explicit attempt to make a machine or a network resource unavailable to its intended users. Attackers interrupt/suspend services of the host connected to internet temporarily or indefinitely.It involves saturating the target machine with external communication requests such that it cannot either respond to legitimate traffic or responds so slowly as to be rendered effectively unavailable. Two general form of Dos attacks are - those attacks that crashes services (computer attack) and those that flood services (network attack). Flooding DDoS attacks produce adverse effects for critical infrastructure availability, integrity and confidentiality. Current defense approaches cannot efficiently detect and filter out the attack traffic in real time. Based on the assumption that the attacker flows are very aggressive than the legitimate users the proposed work provides sufficient bandwidth to genuine users during flooding DDoS attack.The aim of the project is to implement an approach for mitigating DDoS based on “The Interface Based Rate Limiting (IBRL) algorithm”, used to mitigate the identified DDoS attacks. The implementation is carried out on a simulation tool Omnett++ installed on linux machine. The results are the plots that show that there is considerable increase in the two important and significant measures, response time and packet drop metrics for legitimate users even under DoS and DDoS attacks.
The Impact of Operation Tempo: Issues in Measurement

Abstract : Military leaders have repeatedly expressed concern about the toll operations tempo (OPTEMPO) takes on soldier and unit readiness. In a model of OPTEMPO developed by Castro and Adler (1999), peak soldier and unit performance are associated with an optimal level operational demands ( e.g., OPTEMPO), and lower levels of readiness are associated with both lower and higher levels of OPTEMPO. Support for the model was found in a series of psychological screening assessments with U. S. soldiers. For example, when operations tempo was defined as the length of a deployment to Bosnia, greater rates of psychological distress were associated with longer deployments. In contrast, when operational tempo was defined as previous deployment experience, psychological distress rates were lower. Clearly, the operational definition of OPTEMPO is a critical task that is vital to understanding the impact of the pace of operations on soldiers. In an in-depth examination of the OPTEMPO model, we are conducting a two-year study of 10 units across the US Army in Europe. Measures of OPTEMPO include daily work variables such as the average number of hours worked per day and the number of hours worked per week. There are also measures that describe the tempo of a soldier's military experience, including total number of military deployments, deployment intensity (number of deployments/ number of years in the military), and training intensity (number of days on training exercises in the past six months). By addressing these diverse measures of OPTEMPO we hope to identify key variables, as well as moderating variables, that provide evidence for the OPTEMPO-Readiness Link.
MARSHALL MIX DESIGN METHOD: CURRENT PRACTICES

Since its development in the 1940's, the Marshall Method has increasingly been accepted by the highway agencies throughout the world to design and control bituminous paving mixtures. At the present time, 76% of the state highway agencies in the United States use this method. Being an empirical test method which does not measure the fundamental engineering properties of bituminous concrete, the Marshall Method has had its shortcomings despite the overall success. This has led to its modifications by several agencies including the Pennsylvania Department of Transportation (DOT). Among the agencies using the Marshall Method these are significant differences in the procedures and applications. It is quite possible that most of these modifications have been made to suit the local conditions such as available raw materials and mixes, traffic and climate. However, one is amazed to see the wide disparity which exists. This paper outlines the Marshall testing and design procedures used by the various states in the USA and also the Pennsylvania DOT's experience with this method.
Controlling water quality in intermittent supply systems

In countries suffering from chronic water shortages, water distribution systems are often operated on an intermittent basis, leaving them unpressurised and allowing ingress of contaminated groundwater, particularly in areas lacking sewerage systems. The periods of stagnation can promote microbial regrowth, further compromising water quality. On the other hand, peaks in pressure and velocity in the pipe network lead to biofilm detachment events, thus releasing microbial cells that may escape the regular quality monitoring procedures and thus increase risk for the consumer. Finally, intermittent supply requires consumers to store water in household storage tanks, which often encourage bacterial regrowth. This paper reports on research undertaken in Jordan, Lebanon, Palestine, the UK and Portugal, which provided an improved understanding of the factors controlling bacterial concentrations in intermittent supplies, and presents an overview of the most important aspects of water quality control in intermittently operated networks.
Urban propagation modeling for wireless systems

Abstract : Measurements taken in the San Francisco financial district provide new descriptions of propagation effects and extend existing propagation models to quantify the repeatability of signal variation assumed by new resource allocation techniques. The financial district is a flat portion of the city comprising a grid-like pattern of streets surrounded by buildings up to 160m tall and is like many areas that are now experiencing network congestion. Changes of 15-25 dB in signal strength are known to occur in the vicinity of intersections and along orthogonal streets. Previously not studied, the signal strength's rate of change determines how quickly the system must respond to loss of signal quality. The sudden change in signal level at street corners requires an averaging window of less than 5 wavelengths to determine the local average power. A new partitioning technique incorporates the layout of streets to reduce the prediction error of existing path loss models by up to 6 dB. Using a new model, repeatability of large- and small-scale signal variations is quantified over a 15-month period.
Performance Investigation of Microstrip Exponential Tapered Line Impedance Transformer Using MathCAD

Impedance transformer is an essential part of a system which allows two difierent loads to be perfectly connected without any loss due to re∞ections. This paper presents investiga- tions performed on a microstrip exponential taper impedance, ETLI, transformer. Mathematical computations were performed using MathCAD software. The re∞ection coe-cient and return loss responses are in good agreement with theory. Broadband characteristics have been observed. To further investigate the performance of the taper, the ETLI transformer is simulated. Four difierent load impedances have been considered and various lengths of ETLI were investigated. It was found that as the frequency increases, the number of optimum lengths has also increased with a smaller difierence between the optimum lengths. The same pattern occurs with any load impedance, from 70 to 100Ohm. In addition, the behaviour of ETLI transformer with variation of loads at a particular frequency showed that 80Ohm load appeared to be the most matched. As the frequency increases, higher loads are matched with longer ETLI. Difierent loads are well- matched with longer ETLI transformers at higher frequencies from 6GHz.
