Year: 2020

description: The explosive growth of smart devices, network access points, and new mobile application development drives users to use more and more mobile applications and, this has lead to the explosive growth of mobile data traffic. It has a high impact on mobile service providers to manage network data traffic because application usage is different from one location to other with time. Understanding the application-level traffic patterns from a completely different location angle is effective for operators and content providers to create technical and business plans. In this paper, we have established several typical traffic patterns and predict application category traffic demand per clustered location in a mobile cellular network. We explore mobile traffic patterns by clustering each application category into five clusters based on traffic volume and location. Then, we implement a random forest model to predict the traffic demand of three of the most highly utilized applications per cluster location.This outcome could be useful in relevant future applications, with the prospect to achieve average 96% predictive accuracy per application category per cluster. Understanding popular application at the clustered locations and predicting the traffic demand of a popular application could significantly improve user experience, average latency, energy consumption, spectral efficiency, back-haul traffic, and network capacity. Those outcomes are possible via designing and implementing a cache server or planning and optimizing the network resources based on predicted traffic demand.

description: In his Fringe Festival show, Tell Me Lies, comedian and broadcaster Paul Verhoeven tells stories I sincerely hope are not true. This is Verhoeven's first solo show, and the fact it's launching at the Fringe - at Melbourne's Portland Hotel - is presumably based on his success in other genres, namely his sketch-comedy group The Lords of Luxury and his work as an online and radio commentator on games, technology and pop culture.

description: Science is built on the pursuit of answers to fundamental questions and the constant expansion of our understanding of the world around us. However, this effort has not been without challenges and inequalities. This article critically examines the issue of diversity in science and the notable disparities that persist in global scientific knowledge. Throughout history, the contributions of scientists from diverse regions and cultures have been pivotal to scientific advancement. Nevertheless, significant gaps in terms of access, funding, and recognition in the global scientific community still endure. We use the concept of the "abyss," as a metaphor for the disparities in scientific practices across diverse regions of the world within the context of globalization. We seek to shed light on how the abyss influences the very essence of scientific inquiry, ranging from disparities in access to knowledge to the limitations imposed by technology and resources. This article addresses how socioeconomic, gender, and geographical disparities impact who has the opportunity to engage in and lead scientific research. The decolonization of science and the incorporation of indigenous and local perspectives in research are highlighted as crucial ways to address these disparities. Additionally, the concept of participative science is explored as an inclusive approach that allows diverse communities to take part in scientific research. Ultimately, this exploration of diversity in science and disparities in scientific knowledge seeks to inspire deeper reflection on how we can work together to ensure that science becomes a truly global and representative endeavor, enriched by a multitude of perspectives and the collaboration of people from all corners of the world.

description: Telecommunication fraud is remaining challenging since the beginning of commercial telecom service. There are various reasons that makes telecom fraud mitigation inefficient. Some of them are; integration of new technologies without evaluating the security hole, lack of knowledges on the fraud root causes, the changing behavior of fraud and effective use of mitigation techniques. Short Message Service (SMS) is one of the main and victim telecom services. A variety of technologies, services and actors are involved on SMS ecosystem. This technology diversity makes the service vulnerable for different type of messaging frauds. In this study SMS fraud mitigation taxonomy is proposed to improve fraud mitigation deployment method. The taxonomy is constructed from four main nodes namely Technology (Which), Vulnerability (Where), Fraud (How) and Mitigation (What) as a cause and effect way. These main nodes are also categorized in to three sub technological layers which are network/protocol, service and actor. In addition to this classification the mitigation techniques are characterized as technical and none technical. The evaluation process is done first selecting 100,000 fraudulent short message records from ethio telecom. Then taking appropriate mitigation techniques from Network /protocol, Service and Actor layers. Finally, the selected records are examined by each layer mitigation techniques based on the fraud scheme. The layered evaluation result confirmed the proposed approach can mitigate 70% of the fraud messages at network and protocol level, 57.2% at service level, and 84% at actor level before any impact. So that overall efficiency of this taxonomy based layered mitigation approach is recommended to use, instead of detecting the fraud after impacting the service.

description: Satisfaction of customers is the most important factor for mobile operators to be successful. This needs effective customer segmentation and segment targeted mobile service packaging and delivery. Segmentation differentiates customers into multiple groups that manifest different service needs and preferences, thus different service packages. It has been traditionally performed using demographic and value-based segmentation methods based on customer survey data. For improved efficiency, advanced clustering techniques that exploit existing historical customer data from network management system have been applied. Instead of using a single dimension of value-based segmentation, the historical data set with many features was applied to assess the customer service usage behavior from different dimensions. For a dataset with many attributes, such advanced clustering techniques have not been investigated in the Ethiopian context. The thesis work investigates and compares the performance of K-means and expectation-maximization algorithms for usage-based clustering using voice, SMS and internet service usage call detail record data of mobile customers. The performance was compared using metrics such as cluster size or ratio, cluster cohesion or compactness and separation between centroid values. These metrics were used to evaluate the quality of the clustering result of the algorithms in identifying distinguished customer segments from each service usage dataset for mobile service packaging purposes. Optimal cluster size per dataset was determined using elbow method. In the study, data processing and algorithm implementations were performed using WEKA data mining tool. Achieved results indicate that for all the datasets the EM algorithm formed compact clusters with low level of within cluster variance. On the other hand, K-means clustering has a better quality in assigning instances to each cluster fairly. In general, the study identified important additional attributes from the CDR dataset to differentiate customers for mobile service packaging purpose. These additional features enhance the insight on customers to provide well differentiated mobile service packages.

description: The thesis explored the lives of highly-educated, professional Iranian women who migrated to Australia after the Islamic revolution of 1979. The study highlights the roles of gender and education in migration studies, issues not well addressed in previous research studies. It shows that pre-migration experiences of gender discrimination can lead to positive experiences post migration, both in private and public lives. This project makes a significant contribution to the understanding of diversity, how different categories of migrant women adapt to a new environment, and in this case how professional Iranian women have adapted to life in a secular nation.

Comparison and Fine Tuning Empirical Pathloss Models at 1800MHZ and 2100MHZ Bands for Addis Ababa, Ethiopia
Creators: name: Esayas, Andarge
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Pathloss models play a very important role in wireless communications in coverage planning, interference estimations, frequency assignments, Location Based Services (LBS), etc. They are used to estimate the average pathloss a signal experience at a particular distance from a transmitter. Inaccurate propagation models may result in poor coverage, poor quality of service or high investment cost. Both second generation (2G) and third generation (3G) networks in the city of Addis Ababa (AA), Ethiopia, have problems like poor coverage, low data throughput, call drops and others. One of the root causes of these problems is the use of untuned pathloss model during network planning. So, it is mandatory for the operators to select the best fit pathloss model and tune it according to the specific situation the pathloss model is used. This thesis compares three pathloss models; namely, COST231, ECC-33 and SUI and tunes the one that performs best in the specific area type. At 1800MHZ band, COST231 was best in estimating the measured path loss in urban areas with a Root Mean Squared Error (RMSE) of 3.27dB before tuning and the RMSE could improve to 3.25dB after tuning. COST231 was also best in suburban areas with an RMSE of 5.27dB. Tuning the model could improve the RMSE to 4.18dB. SUI was best in open areas. It has an RMSE value of 6.0dB before tuning. Tuning has improved the RMSE value to 4.91dB. At 2100MHZ, 25 sites are used to collect path loss data. Similar analysis was done in the three path loss models. Based on the analysis, SUI is found to be best in predicting the path loss for all the three morphology types. Although ECC-33 was equally competent for urban area sites, SUI could predict the path loss better for the overall all average measured path loss with an RMSE of 4.27dB. Tuning the model could improve the RMSE to 2.23dB. The measured path loss for suburban areas could also be better predicted by SUI with an RMSE value of 5.75dB before tuning and 2.57dB after tuning. Path loss in open areas can also be better predicted by SUI. It has an RMSE value of 6.53dB before tuning. An improvement in RMSE to 3.38dB could be achieved after tuning.

description: Besides the chemotaxonomic value, nowadays determination of biodiversity and chemical variability has a commercial impact. The exact identity of raw material and constituents of botanical products, such as food supplements or herbal remedies, is a very important argument, being the real prerequisite for quality control and traceability, followed by the determination of active components. However, the analytical approach must consider the natural great variability in secondary metabolites and product form, such as in extracts. Against the reductive approach, on the basis of single chemical standards, so far dominant in Pharmacopoeias monographs, we report applications and utility of the high-performance thin-layer chromatography fingerprint in determination of species of the same genus, of populations of the same species and of different drugs of the same plant.

description: The way one evaluates and justifies knowledge (their way of knowing) has important implications for reasoning in a post-truth world full of misinformation and fake news. Using a mixed methods approach, this research explored how people know what they know. Interviews with six adults revealed the justifications, sources, influences, meaning, and outcomes of knowledge and knowing. A follow-up survey with 345 adults identified three groups of individuals that use different means of justification across various socio-scientific topics. The results contribute to current models and measures of knowing and can be used when developing interventions to promote adaptive approaches to knowing.

description: The greatest accomplishments of Thomas Jefferson's presidency were the purchase of the Louisiana territory, which doubled the size of the United States, and the discoveries made by the Lewis and Clark expedition. These were not just single events that sprang into being in 1803, as we learned in elementary school, but the fulfillment of a lifetime of study and effort for Jefferson. Many factors influenced Jefferson to make the decisions that culminated in these twin events.

This thesis examines the role of Doctor Thomas Walker, who was Thomas Jefferson*s guardian, neighbor, and friend, to demonstrate the influence of a lesser-known person on the larger issues of America's westward movement. This study intends to consider Thomas Walker's life in terms of the long relationship between the Walker and Jefferson families to discover in what ways and to what extent Thomas Walker might have influenced Thomas Jefferson. In his instructions outlining the goals of the Lewis and Clark expedition, Jefferson reflects Walker's attitudes towards land exploration and mapping, using the land as a resource and developing relations with the natives.

Primary materials used to support this thesis were the words of the men themselves. The author examined the journal of Thomas Walker's 1750 journey of exploration, correspondence between the two men, government records of their actions as public servants, and Thomas Jefferson's Summary View of the Rights of British America and Notes on the State of Virginia in order to establish Walker's influence over Jefferson in terms of their personal philosophies about land and relationships with natives. Further examination of President Jefferson's instructions to Meriwether Lewis demonstrated how those philosophies influenced the mission of the Corps of Discovery*s exploration of the Louisiana Purchase.
The electoral reform campaigns in New Zealand: a political communication case study
Creators: name: Roper, Juliet

Year: 2024

description: Communication professionals employed in the public relations and advertising industries play a central role in the democratic process. They research, design, and implement the campaign strategies that attempt to influence voter choices and public policy. In New Zealand, some special legal restrictions are placed on the campaign activities of politicians during election campaigns. But, for corporations and interest groups, the ability to pay is the major controlling factor. It was within the context of this 'free market' of ideas that New Zealand held a referendum to decide whether or not to adopt a new electoral system. In spite of a government-sponsored campaign aimed at educating the public about the issues involved, the main discourse of the debate emanated from two interest groups. One, the Campaign for Better Government, was a predominantly corporation-sponsored lobby group which worked to maintain the status quo. The other group, the Electoral Reform Coalition, was a grassroots organisation, led mainly by academics, trade unionists, and members of the Women's Electoral Lobby, which worked for proportional representation. In this paper, we analyse the campaigns run by the two protagonists. We examine the strategies and techniques, such as poll-driven advertising, used by communication professionals, and then compare the professional campaign with that produced by amateurs. We conclude by discussing the wider implications of communication professionals' involvement in the political sphere (Putnis,1993).

description: The scope of the present work is a numerical and experimental investigation about the range of validity in terms of applicability of CH$_{2}$OxOH as a marker for the heat release rate (HRR) for fuel-rich air to pure oxy-fuel flames including preheating and elevated pressure. Therefore, laminar, freely propagating 1d CH$_{4}$ flames were calculated, where oxygen content in the oxidizer (from air to pure oxy-fuel combustion), inlet temperature and pressure were varied for a wide range of the equivalence ratios. The preheat temperature and pressure were parametrically changed from 300 K to 573 K and 1 bar to 5 bar, respectively. Different reaction mechanisms were used, namely GRI30, DLR, USC/II, Caltech2.3 and ABF. The performance of the CH$_{2}$OxOH as a marker for HRR is assessed in terms of correlation coefficients of their profiles in laminar flames. The comparison of the obtained correlations of CH$_{4}$/air and CH$_{4}$/O$_{2}$ flames shows that in case of air combustion, the HRR can be accurately estimated by the product of CH$_{2}$OxOH for slightly rich flames (Φ = 1.5), whereas the quality of the correlation degrades with increasing equivalence ratio. In contrary, the correlation coefficient increases with higher equivalence ratios in the fuel-rich domain for enhanced oxygen contents in the oxidizer. For pure oxyfuel combustion, the best correlation is found at an equivalence ratio of approximately Φ = 3.0. Elevated pressure leads in all flames to better correlations at lower equivalence ratios compared to standard inlet conditions, whereas preheating induces the opposite trend and expands the valid regime. A series of CH$_{4}$/air flames were also investigated experimentally in a range of the equivalence ratio between 1 < Φ < 2 at standard inlet conditions. The qualitative CH$_{2}$O (excitation at 355 nm) and OH (excitation at 283 nm) concentration were resolved applying two-dimensional LIF for flames stabilized at a McKenna burner. Comparisons show similar trends for measurements and numerical simulations.

description: Questo articolo analizza l’aumento della profittabilità delle banche europee seguito al rialzo dei tassi di interesse di riferimento da parte della BCE nel 2022. Si discute inoltre in che misura il termine ‘extraprofitto’ sia appropriato per questo recente aumento della profittabilità bancaria. Per superare le disparità distributive derivanti, una buona politica economica potrebbe consistere nell’implementazione di banche pubbliche. Inoltre, una partecipazione significativa dello Stato nel settore bancario potrebbe avere importanti ripercussioni nella promozione e nell’incentivazione di comportamenti ritenuti virtuosi, dalle politiche ambientali a quelle occupazionali. Lo strumento della banca pubblica è già presente nella politica economica di molti paesi e la sua implementazione può rappresentare un punto di svolta nella politica monetaria, fiscale e industriale.

description: Con le misure di quantitative easing adottate nello scorso quindicennio la politica monetaria è passata da una implementazione tecnica basata sulla scarsità di riserve ad una basata sull’abbondanza delle riserve. A loro volta i sistemi bancari hanno adattato i propri comportamenti all’abbondanza di riserve complicando il ritorno al precedente sistema. La questione riguarda anche la politica fiscale in quanto, con il rialzo dei tassi di interesse, l’abbondante liquidità bancaria è remunerata dalle banche centrali a tassi che erodono la loro profittabilità. La distribuzione della liquidità fra le banche commerciali europee e un poco noto meccanismo di ripartizione di costi e profitti fra le banche centrali dell’Eurosistema fanno sì che il sussidio de facto alle banche europee (quasi 120 miliardi all’anno) favorisca soprattutto i paesi d’oltralpe. Il paper aggiorna nozioni e vicende di politica monetaria già esposte in forma divulgativa in Cesaratto (2021a), anche a supporto didattico di colleghi e studenti.

description: In the rapid development of information technology, many enterprises are challenged by seamless information exchange and resource sharing requirement in a heterogeneous enterprise environment. However, service-oriented middleware technologies can provide a better solution in facilitating seamless resource sharing and information exchange among integrated enterprise applications. It is important to carefully design flexible and scalable integration architecture to create and support a well-performing enterprise system. In this research, a Data Synchronization Solution Model (DSSM) is designed and implemented to overcome a data synchronization problem in a heterogeneous enterprise environment. The case study and the research idea are initialized based on existing real problems in ethiotelecom working environment. The company faces data synchronization problem between integrated applications. The data in the different application databases have mismatch; for example, for the same customer its service status could be active in one application and barring in another. As a solution, a data synchronization solution model is proposed based on middleware and knowledgebase. The middleware is a message processing part that receives the incoming message, processes and forwarded the message to a destination suitable data format. The knowledgebase is a database for the common data exchanged among integrated applications; which becomes a common data reference for integrated applications. To implement and validate the data synchronization solution model we simulate a heterogeneous enterprise environment using virtual machines, with different operating systems and databases. The implementation and validation is performed based on the company's SIM card replacement business process. To simulate the message processing, we design Simple Object Access Protocol (SOAP) message with similar message structure in the company. The message processor is designed and implemented using open source WSO2 enterprise integrator tool. The validation result indicates, the practicality of DSSM hypothesis to creating consistency and synchronize data among integrated applications in a heterogeneous environment. The result also shows the features and components of DSSM are functioning per the design specified in the research document. Moreover, unlike the existing system in which the case study is based upon, the new solution is flexible for maintenance and redesign.

description: Structural, chemical, magnetic and thermodynamic properties of palladium clusters Pdn with n = 2–11 are studied using density functional methods. The average bond length, entropy, enthalpy and polarisability are observed to increase as the cluster grows in size. The binding energy per atom also increases with cluster size. Stability function and atom addition energy change predict that Pd4, Pd6 and Pd9 are relatively more stable than their neighbouring clusters. Electron affinity, electronegativity and electrophilicity values suggest that larger clusters have stronger tendency to accept electrons, thereby supporting the relative stability of Pd4 and Pd6. Chemical hardness is also seen to decrease with cluster size, which suggests that large clusters are more prone to changes in their electronic structure. The magnetic properties of these clusters are reported.

description: Der eine hat die Antikörper. Die andere hat sie nicht. Der eine hat im Impfpass stehen, dass er immun ist. Die andere kann sich nicht ausweisen. Der eine darf alles. Die andere darf nichts. Soll das unsere Wirklichkeit sein in der nächsten Phase der Coronakrise? Gesundheitsminister Spahn will einen Immunitätsausweis im Infektionsschutzgesetz verankern. Spaltet das die Gesellschaft in Privilegierte und Freiheitsbeschränkte? Aber wenn jemand immun und damit weder gefährlich noch gefährdet ist – mit welchem Recht kann man dann von ihm noch verlangen, seine Freiheit zu beschränken? In der heutigen Folge von Corona Constitutional spricht Max Steinbeis über diese Fragen mit der Gesundheitsrechtsspezialistin ANIKA KLAFKI von der Universität Jena.

description: The degree of resin cure achievable in urea formaldehyde (UF) resin is known to influence the hydrolytic stability of UF resin. In the current study, a significant difference in water extractable resin components has been observed between cured pure resin and that from medium density fiberboard (MDF) panels. Results show some 50 to 70% of resin components may be removed on water extraction from resinated MDF fiber and panel samples. In contrast, cured pure UF resins have only a small fraction of resin mass extractable into water with nitrogen-containing components remaining incorporated into the cured resin. The relatively high resin mass losses from panel material together with loss of nitrogen-containing components suggest not only free urea, but urea-methylene species are labile and readily extractable into water. Wax contributes to differing panel extractability when pressed at either 100 or 160°C, whereas panel resin loading has a significant effect on extractable resin components. A lower resin loading led to relatively greater resin extractability, which was corroborated by the extractability of resin-fiber mixtures up to 50% resin content. An assessment of extracted panel residues suggests a relative decrease of urea and urea-formaldehyde condensation products after water extraction. With UF resin highly mobile on fiber during MDF manufacture, the results suggest resin components may separate, leading to their incomplete incorporation into a cured, cross-linked UF resin matrix, with an implication that resin cure on fiber may not be complete compared to that found with pure resin.

description: Benzodiazepines have been widely used therapeutically for their ability to act as tranquilizers, sedative-hypnotics, antiepileptics and frequently prescribed to women during pregnancy for managing preeclampsia or eclampsia. The present report deals with quantitative structure–toxicity relationship (QSTR) modelling of a series of benzodiazepines, in the context of the 3R concept, to provide an insight into the main structural fragments that impart toxicity to these molecules. Three different in silico techniques, namely descriptor-based QSTR, group-based QSTR and 3D-toxicophore mapping, were employed to obtain statistically significant models. Multiple in silico models made it possible to reach a unified conclusion regarding the structural fragments and features responsible for the toxicity and provide consensus predictions which can be effectively utilised to design and predict less toxic new benzodiazepines.

description: Heart rate variability (HRV), defined as the variability between successive heart beats, is a noninvasive measure of autonomic nervous system (ANS) function, which may be altered following traumatic brain injury (TBI). This scoping review summarizes the existing literature regarding changes in HRV after TBI as well as the association between measures of HRV and outcomes following TBI. A literature search for articles assessing ‘heart rate variability’ and ‘brain injury’ or ‘concussion’ was completed. Articles were included if HRV was measured in human subjects with TBI or concussion. Review articles, protocol papers, and studies including non-traumatic injuries were excluded. Sixty-three articles were included in this review. Varied methods were used to measure HRV in the different studies. Forty articles included information about differences in HRV measures after TBI and/or longitudinal changes after TBI. Fifteen studies assessed HRV and symptoms following TBI, and 15 studies assessed HRV and either functional or cognitive outcomes after TBI. HRV has been studied in the context of mortality, clinical symptoms, and medical, functional, or cognitive outcomes following TBI. Methods used to measure HRV have varied amongst the different studies, which may impact findings, standardized protocols are needed for future research.

description: Unser heutiges Thema hat mit Corona unmittelbar gar nicht so viel zu tun, mit Krise dafür um so mehr: Es geht um Polen, um das polnische Verfassungsgericht, das in dieser Woche ein Urteil gefällt hat, das, sagen wir mal, erklärungsbedürftig ist. Dieses Urteil, um das Ergebnis vorweg zu nehmen, springt nicht nur mit dem polnischen Verfassungsrecht, sondern auch und vor allem mit dem Europarecht auf beispiellos brachiale Weise um. Darüber spricht Max Steinbeis mit einem Europarechtler, der sich sowohl mit dem Verhältnis von nationaler Verfassungsgerichtsbarkeit zum EU-Recht als auch mit dem speziellen Fall Polen viel beschäftigt hat und obendrein ein langjähriger Freund und Autor des Verfassungsblogs ist, nämlich FRANZ MAYER von der Uni Bielefeld.

description: An diesem Sonntag wird in Polen ein neuer Präsident gewählt. Offiziell. Die Sache ist nur, dass an diesem Sonntag in Polen kein neuer Präsident gewählt wird. Die Regierung hat keine Wahl organisiert bekommen, will stattdessen vom Obersten Gerichtshof diese Wahl-Nichtwahl für ungültig erklären lassen, dahinter steckt ein elaboriertes politisches Kalkül, das aber im ganz großen Stil schief gehen könnte. Extrem spannende und riskante Zeiten also in Polen, und darüber spricht Max Steinbeis in der heutigen Folge unseres Krisenpodcasts mit einem Mann, der seit vielen Jahren als eine der letzten von der Regierungspartei PiS unabhängigen Institutionen des Staates gegen den Zerfall der Rechtsstaatlichkeit ankämpft, nämlich mit dem Bürgerrechtsbeauftragten ADAM BODNAR, der obendrein auch noch eine Botschaft an das deutsche Bundesverfassungsgericht mitgebracht hat.
