Designing Mobile Information Services; An approach for Organisations in a Value Network

The mobile telecommunications industry is searching for new services, not only to recoup its investments but also to stay competitive in the future. The industry is undergoing a radical transformation and organisations in the telecommunications, information technology and media sector are becoming increasingly interdependent. Organisations have to collaborate in value networks to create new mobile information services. The challenge is to design services in these complex networks that provide value for all actors including the customer. In this research we explore an approach to design mobile information services. Mobile information services are a product of fast developing technology, unpredictable demand from customers and a value network created by the involved actors. We present four case studies. The first three are the WAP based M-info service and the iMode based Radio 538 ringtune service and Finder service. The last case study concerns the action research project âMIES on the campusâ. In this project we designed and implemented a mobile information and entertainment service for campus visitors on a UMTS testbed at Delft University of Technology. The main deliverable of this research is a design approach that consists of guidelines, control mechanisms, predefined activities, models, and supporting tools.
A study on the fundamental transmission experiment for wireless power transmission system

This paper reports a development to perform microstrip rectenna (rectifying antenna) microwave-DC conversion of high-efficiency for wireless power transmission centering on 2.45 GHz. A 20/spl times/20 array rectenna system for fundamental wireless power transmission is considered for the development. We combined several array rectennas in series and parallel in a modular way so that microwave-DC conversion efficiency could be superior. In experiments, the conversion efficiency of a unit rectenna was 75.6% and the entire efficiency from transmitter to receiver of wireless power transmission system was about 33%.
The Atherosclerotic Profile of a Young Symptomatic Population between 19 and 49 Years: Coronary Computed Tomography Angiography or Coronary Artery Calcium Score?

(1) Background: Whether coronary computed tomography angiography (CTA) or the coronary artery calcium score (CACS) should be used for diagnosis of coronary heart disease, is an open debate. The aim of our study was to compare the atherosclerotic profile by coronary CTA in a young symptomatic high-risk population (age, 19–49 years) in comparison with the coronary artery calcium score (CACS). (2) Methods: 1137 symptomatic high-risk patients between 19–49 years (mean age, 42.4 y) who underwent coronary CTA and CACS were stratified into six age groups. CTA-analysis included stenosis severity and high-risk-plaque criteria (3) Results: Atherosclerosis was more often detected based on CTA than based on CACS (45 vs. 27%; p < 0.001), 50% stenosis in 13.6% and high-risk plaque in 17.7%. Prevalence of atherosclerosis was low and not different between CACS and CTA in the youngest age groups (19–30 y: 5.2 and 6.4% and 30–35 y: 10.6 and 16%). In patients older than >35 years, the rate of atherosclerosis based on CTA increased (p = 0.004, OR: 2.8, 95%CI:1.45–5.89); and was higher by CTA as compared to CACS (34.9 vs. 16.7%; p < 0.001), with a superior performance of CTA. In patients older than 35 years, stenosis severity (p = 0.002) and >50% stenosis increased from 2.6 to 12.5% (p < 0.001). High-risk plaque prevalence increased from 6.4 to 26.5%. The distribution of high-risk plaque between CACS 0 and >0.1 AU was similar among all age groups, with an increasing proportion in CACS > 0.1 AU with age. A total of 24.9% of CACS 0 patients had coronary artery disease based on CTA, 4.4% > 50% stenosis and 11.5% had high-risk plaque. (4) Conclusions: In a symptomatic young high-risk population older than 35 years, CTA performed superior than CACS. In patients aged 19–35 years, the rate of atherosclerosis was similar and low based on both modalities. CACS 0 did not rule out coronary artery disease in a young high-risk population.
Charge Trapping and Annealing in High- Gate Dielectrics

We examine the radiation response, annealing char- acteristics, and long-term reliability of capacitors with Al gates and Al O -SiO N gate dielectrics stacks which received a forming gas anneal (FGA) or an O and FG anneal after high- deposition. By comparison to a theoretical capacitance-voltage (CV) curve, the FG annealed devices are found to have a large preirradiation inter- face trapped charge density of cm , whereas devices annealed in O and FG show a large density cm ) of negative bulk charge. The midgap voltage shift in- creases monotonically with dose for both sets of devices, but the O annealed devices exhibit 50% less trapping at a total dose of 2 Mrad(SiO ). The radiation-induced voltage shifts are found to recover during long duration biased anneals as a result of tun- neling and thermal annealing. For short times and large biases, the annealing response is found to be dominated by tunneling. After 1,000 s of annealing, there is a 50% reduction in for de- vices annealed at 2.0 MV/cm and a 7.5% recovery for devices an- nealed at 1.0 MV/cm. For longer times, the annealing response of these devices is dominated by thermal annealing. Accelerated life testing shows these devices have a broad failure distribution with a large population of extrinsic failures. Extrapolation of the relia- bility data suggests these particular devices would have to be oper- ated at an electric field less than 2.5 MV/cm to achieve a ten-year operational lifetime. Improved reliability is, therefore, required be- fore insertion into a manufacturing environment. Index Terms—Alternative dielectric, annealing, bias depen- dence, high- , interface trap, MOS capacitor, oxide trapped charge, processing, radiation effects, radiation response, relia- bility.
The link between fake news susceptibility and political polarization of the youth in the Philippines

ABSTRACT This study explores the relationship between political polarization, measured as pro-administration and opposition support, and vulnerability to online misinformation through a survey distributed through snowball sampling among students in colleges and universities across the Philippines. Using quasibinomial models, a two-model approach was conducted to disentangle the accuracy goals and partisan goals of the students. We find that polarized supporters of President Duterte are more likely to inaccurately identify fake and real news, compared to polarized supporters of the opposition. This is remarkably similar to trends in the United States where Republicans are more vulnerable to misinformation. Other results also highlight possible trends, such as the link between increased self-reported frequency of seeing fake news and decreased likelihood of correctly identifying fake news, and the link between increased trust in news in social media and decreased odds of correctly identifying both real and fake news.
Associations between Lifestyle Behaviors and Quality of Life Differ Based on Multiple Sclerosis Phenotype

Multiple sclerosis (MS), a neuroinflammatory disorder, occurs as non-progressive or progressive phenotypes; both forms present with diverse symptoms that may reduce quality of life (QoL). Adherence to healthy lifestyle behaviors has been associated with higher QoL in people with MS; whether these associations differ based on MS phenotype is unknown. Cross-sectional self-reported observational data from 1108 iConquerMS participants were analysed. Associations between lifestyle behaviors and QoL were assessed by linear regression, and phenotype differences via moderation analyses. Diet, wellness, and physical activity, but not vitamin D or omega-3 supplement use, were associated with QoL. Specifically, certain diet types were negatively associated with QoL in relapsing-remitting MS (RRMS), and positively associated in progressive MS (ProgMS). Participation in wellness activities had mixed associations with QoL in RRMS but was not associated in ProgMS. Physical activity was positively associated with QoL in RRMS and ProgMS. Phenotype differences were observed in diet and wellness with physical QoL, and physical activity with most QoL subdomains. Our findings show lifestyle behaviors are associated with QoL and appear to differ based on MS phenotype. Future studies assessing timing, duration, and adherence of adopting lifestyle behaviors may better inform their role in MS management.
Numerical Modelling of Microstrip Patch Antennas

EMC is concerned with the generation, transmission, and reception of electromagnetic energy. These three aspects of the EMC problem form the basic framework of any EMC design. A source (also referred to as an emitter) produces the emission, and a transfer or coupling path transfers the emission energy to a receptor (receiver), where it is processed, resulting in either desired or undesired behaviour. Interference occurs if the received energy causes the receptor to behave in an undesired manner. Antennas are especially the emitters of electromagnetic energy. This paper is about modelling and analyzing microstrip patch antennas. It contains the precise modelling of the antenna and the near field, far field, impedance and other characteristics of the antenna. After analyzing the near field and far field of the antenna, it can be optimized.
The Impact of Social Media Activities on Brand Equity

This study aims to investigate the impact of Social Media Activities on brand equity (brand awareness and brand image). A cross-sectional quantitative study has been conducted using a validated questionnaire distributed to a convenience sample of 362 participants who used one or more forms of an Airline’s social media. Multiple Regression analysis was performed using SPSS version 20 to test the hypotheses. Results revealed a significant impact of Social Media Activities as a whole on brand equity. It was found that entertainment, customization, interaction and EWOM significantly affected the brand image, while customization, trendiness, interaction and EWOM significantly affected brand awareness. This study is one of few to examine the impact of social media activities on brand equity towards Airlines in Middle Eastern countries. The study provided several theoretical and practical implications that can benefit airline managers in their marketing efforts using various social media activities.
Effects of Materialism on Brand-Related User-Generated Content and Positive WOM on Social Media

This research investigates how materialism as a personality trait can impact consumers’ intention to create brand-related user-generated content (UGC) and positive WOM on Facebook. The research involved three studies. Study 1 was an online survey investigating the association between materialism and brand-related UGC and positive WOM creation on Facebook. Study 2 tested the mediating role of the perception of brand symbolism for the effect of materialism on brand-related UGC and positive WOM creation. Study 3 was an online experiment which manipulated materialism. It demonstrated that the perception of brand symbolism mediated the effect of materialism on brand-related UGC and positive WOM creation on Facebook. These findings show how materialism influences whether consumers create content about brands to express self-identity. They also show researchers and managers how to target consumers to encourage them to create brand-related UGC and positive WOM on social media. Specifically, by emphasising materialistic cues, marketers can enhance consumers’ perception of brand symbolism which can motivate consumers to create brand-related UGC and positive WOM.
Improving the E-Commerce Business Model in a Sustainable Environment

The purpose of this study is to develop a comprehensive methodological approach to assess the sustainability of the e-commerce business model based on the integration of key performance indicators into a single vector of business model sustainability. The proposed vector approach allows for predicting and evaluating the effects of different kinds of measures, identifying and implementing the most effective tools for sustainable e-commerce business development. The methodology of this study is based on correlation, cluster and regression analysis. The scientific contribution of this study is the proposed methodological approach, which not only allows one to analyze business model sustainability, but also to compare companies in a competitive environment to determine the priorities of their functioning to achieve leadership positions on the background of sustainable development. The correlation analysis proved that in modern conditions, both economic and environmental components are significant for business model effectiveness in e-commerce. The clustering of the studied e-commerce companies provided an opportunity to take into account the peculiarities of the studied companies, to group them by similar performance indicators. This made it possible to develop more accurate regression models for each cluster. In this case, there is a correlation between the sustainability vector of the business model of a company and its assignment to a particular cluster. The conducted modeling and determination of the level of business model sustainability allowed for determining a relationship between it and the performance of e-commerce companies in the context of economic, environmental and social dimensions. At the same time, the results show that increasing the sustainability vector brings a company closer to the business sustainability benchmark.
Effects of Different Pilot-Scale Milling Methods on Bioactive Components and End-Use Properties of Whole Wheat Flour

The health benefits from consumption of whole wheat products are widely recognized. This study investigated the effects of different pilot-scale milling methods on physicochemical properties, bioactive components, Chinese steamed bread (CSB), and Chinese leavened pancakes (CLP) qualities of whole wheat flour (WWF). The results indicated that WWF-1 from the reconstitution of brans processed by a hammer mill had the best CSB and CLP quality overall. WWF from entire grain grinding by a jet mill (65 Hz) contained the highest concentration of bioactive components including dietary fibers (DF) and phenolic acids. A finer particle size did not necessarily result in a higher content of phenolic antioxidants in WWF. DF contents and damaged starch were negatively correlated with CSB and CLP quality. Compromised reduced quality observed in CLP made from WWF indicated its potentially higher acceptance as a whole-grain product.
Modelling Maximum Stem Basal Area Growth Rates of Individual Trees of Eucalyptus pilularis Smith

The growth rate of a tree at any time relates to its size and the level of competition exerted by its neighbors for the resources it needs for growth. This work describes the development of a model to predict the maximum growth rate in stem basal area of Eucalyptus pilularis Smith trees in native and plantation forests of subtropical eastern Australia. It shows maximum growth rates increasing with size until the tree reaches a stem diameter at breast height of 27 cm. Thereafter, maximum growth rates decline progressively as the tree grows larger. Physiological reasons that might describe this growth pattern are discussed. The maxima are shown to be independent of tree age, stand stocking density or average tree size, and the productive capacity of the site on which the forest is growing. The maximum possible growth rate in stem diameter of a Eucalyptus pilularis tree growing in subtropical eastern Australia is found to depend only on tree size, not its age nor the productive capacity of the site on which it is growing. It increases until stem diameter reaches a certain size and decreases progressively thereafter as the tree continues to grow. There are interesting physiological reasons that may explain this pattern of growth.
Investigation of ultra-thin gate oxide reliability behavior by separate characterization of soft breakdown and hard breakdown

It is shown in this work that the soft breakdown can follow a significantly different temperature and field acceleration behavior than the dielectric breakdown (hard breakdown). These properties have a strong influence on reliability prediction of ultra-thin oxides and can result in misinterpretation if soft breakdown and hard breakdown events are mixed up during gate oxide reliability testing. The activation energy and the field acceleration of the soft breakdown are compared to the disturbed-bond breakage process proposed in the thermochemical E-model. It is concluded that soft breakdown can be caused by H-Si and H-O bond breakage due to the electric field in the oxide. The activation energy for soft breakdown also indicates that formation of a soft breakdown path is influenced by hydrogen diffusion in the oxide.
THE EVALUATION OF MILKABILITY OF SLOVAK PINZGAU CATTLE BY LACTOCORDER

This paper is focused on the evaluation of milkability of Slovak Pinzgau cattle, using mobile measuring device called Lactocorder. The main group of Slovak Pinzgau dairy cows was divided according to the order of lactation (according to parity) into the experimental groups in order to carry out a comparison of traits and parameters of milkability, obtained by Lactocoder within these groups. An important objective of our study was to detect the length and the thickness of the left rear teat of the cow after each measuring by Lactocorder and also to collect the samples of milk for somatic cell count. Totally 94 Slovak Pinzgau dairy cows were evaluated. All measurements were carried out during one weak on a farm located in the eastern Slovakia. The average total milk yield was 8.13 ± 2.42 kg per milking, with an average milk flow rate of 1.76 ± 0.49 kg.min -1 and average maximum milk flow rate of 3.08 ± 0.90 kg.min -1 . The total milk yield showed a positive correlations with average milk flow rate (r = 0.69+++) and with maximal milk flow rate (r = 0.42+++). Based on so called milk flow curves provided by Lactocorder, the course of milking can be evaluated. The milk flow curves display the occurrence of bimodality and duration of each phase of the milking process. The occurrence of bimodality (which can be characterised as a steep decrease of milk flow in time up to 96 seconds after the beginning of milking) was 32.98 %. Positive correlation was found between bimodality and duration of the incline phase (r = 0.74+++) and negative correlation was found between bimodality and quantity of milk acquired during first minute of milking (r = -0.46+++). The mean somatic cell count in our experiment was 297 426 cells.ml -1 . The average length of the teat was 50.84 ± 9.19 mm and the average thickness was 25.17 ± 2.55 mm. Information and results concerning milkability and milking, provided by Lactocorder can be very helpful for a farmer in connection with displacing the mistakes, which could be made during milking process or milking readiness.
THE GAME OF STORES: SIMULATING RETAIL SITE SELECTION AND PROFITABILITY

ABSTRACT Retailers are faced with the challenge of how many stores to operate in a potential or an existing market and where those stores should be located. Various factors influence this decision-making. For instance, the customer behavior and their demographic characteristics, customer travel times, presence of competitors, costs involved, location profitability, etc. Literature in retailing points out various gravity laws that assist retailers to make the location choice decision. ‘Game of Stores” is a board game-based simulation designed for classroom teaching that incorporates the principles of Huffs Law to create a dynamic environment for participants. The gameplay is devised to mimic reality in a competitive setup and to provide participants with similar challenges faced by retailers in real-time. The simulation is intended to help participants comprehend, analyze, and apply the concepts related to retail store location decisions in a gamified environment and to test their analytical skills in optimizing retail location choice and profitability. The applied nature of the game makes it suitable for use in Retail Management courses for students specializing in Marketing.
Geometric component of charge pumping current in nMOSFETs due to low-temperature irradiation

The geometric component of charge pumping current was examined in n-channel metal-oxide-silicon field effect transistors (MOSFETs) following low-temperature irradiation. In addition to the usual dependencies on channel length and gate bias transition time, the geometric component was found to increase with radiation-induced oxide-trapped charge density and decreasing temperature. A postirradiation injection of electrons into the gate oxide reduces the geometric component along with the density of oxide-trapped charge, which clearly demonstrates that the two are correlated. A fit of the injection data to a first-order model for trapping kinetics indicates that the electron trapping occurs predominantly at a single type of Coulomb-attractive trap site. The geometric component results primarily from the bulk recombination of channel electrons that fail to transport to the source or drain during the transition from inversion to accumulation. The radiation response of these transistors suggests that Coulomb scattering by oxide-trapped charge increases the bulk recombination at low temperatures by impeding electron transport. These results imply that the geometric component must be properly accounted for when charge pumping irradiated n-channel MOSFETs at low temperatures.
Standing Work: Carpet vs. Concrete

A significant part of the workforce works with the feet and legs in a relatively static standing position. In an experiment, 20 college students (mean age = 23) stood wearing 2 pairs of socks but no shoes at a table for 240 minutes (120 minutes on carpet on one day and 120 minutes on concrete on another day). Ten subjects stood in the morning and 10 in the afternoon. Foot volume and instep vertical and horizontal circumference and calf circumference did not differ significantly between morning and afternoon or between carpet and concrete. Heart rate did not differ between morning and afternoon but the 95.2 for carpet was significantly lower than the 100.1 for concrete. Perceived comfort ratings were higher for carpet than concrete. Body areas in which comfort decreased the most while on concrete were: lower leg, upper leg, ankle, whole foot, the neck and the shoulder. When the individual factors were combined into a single factor using factor analysis, the 77.7 score (0–100 scale) for carpet was significantly better than the 71.9 for concrete.
Determining the Number of Probe Vehicles for Freeway Travel Time Estimation by Microscopic Simulation

Using probe vehicles to collect real-time traffic information is considered an efficient method in real-world applications. How to determine the minimum number of probe vehicles required for accurate estimate of link travel time is a question of increasing interest. Although it usually is assumed that link travel time is normally distributed, it is shown, on the basis of simulation results, that sometimes this is not true. A heuristic of determining the minimum number of probe vehicles required is developed to accommodate this situation. In addition, the impact of traffic volume on the required probe vehicle number is discussed.
