description: It is well known that guinea pig β2 adrenoceptors (Gβ2ARs) and human β2 adrenoceptors (Hβ2ARs) have structural similarity. However, only one conformational state of Gβ2ARs has been studied – the putative inactive state. As adrenoceptors have a repertoire of conformations, and there is evidence that a certain conformation is stabilised as a ligand approaches, the aim of this study was to build four models of Gβ2ARs by using putative active/inactive Hβ2AR conformers as a template. We evaluated the accuracy of these models in regard to the binding mode and affinity values of a set of known β2AR ligands through docking and molecular dynamics simulations. During docking simulations, ligands reached Gβ2AR sites similar to those reported for Hβ2ARs. The greatest differences between conformational states were found in the domains (TM5 and TM6) previously suggested as being key to ligand recognition. The coefficients of determination between experimental and calculated affinity values were near to but less than 0.66 in all cases. The highest values were for agonists on the active models and antagonists on the inactive model. The four Gβ2AR models proved useful for analysing agonist/antagonist activity. The results suggest that the selection of an adequate model is dependent on the intrinsic activity of a given ligand.

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.

Year: 2018

description: Enterprise Application Integration (EAI) as a solution combines processes, standards, software and hardware for the seamless integration of different enterprise systems in order to operate and function as one. The success of EAI deployment is highly dependent on a proper selection of EAI solution patterns. ethio telecom's enterprise systems are integrated and interoperated using EAI techniques. However, many organizations including ethio telecom, have the difficulty of selecting proper EAI solution patterns. Thus, several EAI solution pattern projects fail to deliver the service that the business is expecting. The objective of this thesis is to develop an integration pattern selection framework, which is used for the selection of an appropriate EAI solution pattern from the available real world's design decisions. The research therefore studied the company's end-to-end enterprise systems' business scenario, by conducting interviews and group discussions with selected staffs, and also referred world's scientific related works and literatures. Case study for validating the framework is also implemented. The proposed framework has the basic activities like: describing business process requirements for integration, studding the environments' development context and integration purpose, examining the integration data and interfaces, modeling of data, mapping of those models, defining of EAI requirements specification, and finally selection of optimal EAI solution pattern, from the available EAI solutions' patterns based on studied evaluation criteria. The framework has been evaluated using three different case studies; by taking ethio telecom's existing integrated enterprise systems and also the forthcoming integration technology parameters. It is then reviewed and evaluated by the internal experts of the company. The main contribution of this research is: to support the company in choosing a suitable EAI solution pattern accommodating both technical and organizational measures, and to increase its' level of success by implementing appropriate EAI solution, which avoids some drawbacks between packaged and third party systems in relation to interoperability, and flexibility issues.

description: Obiettivo di questo saggio è mostrare come la crescita sostenuta del tasso di occupazione, che dovrebbe essere assunta come variabile strategica della politica economica, dipenda – per dati tassi di crescita del prodotto e della popolazione in età lavorativa – da due condizioni: (a) permettere che le ore di lavoro diminuiscano allo stesso ritmo con cui cresce la produttività oraria del lavoro; (b) permettere che i salari orari reali aumentino al ritmo con cui cresce la produttività oraria del lavoro. Il saggio evidenzia che le due condizioni enunciate ed esaminate analiticamente sono da considerarsi come condizioni necessarie affinché l’espansione della domanda e della produzione esprima il massimo potenziale di crescita dell’occupazione a quote distributive invariate. Una volta soddisfatte entrambe, i benefici dell’aumento della produttività oraria del lavoro si trasferiscono ai salari sotto forma di un più alto tasso di crescita dell’occupazione. Il quadro analitico sviluppato nel saggio viene utilizzato per una prima valutazione dell’evidenza empirica.

description: The adsorptive and diffusive behaviour of methane and carbon dioxide in amorphous nanoporous adsorbents composed of spherosilicate building blocks, in which isolated metal sites have been distributed, is examined. The adsorbent contains cubic silicate building blocks (spherosilicate units: Si8O20), which are cross linked by SiCl2O2 bridges and decorated with either –OTiCl3 or –OSiMe3 groups of the other cube corners. The model structures were generated to correspond to experimentally synthesised materials, matching physical properties including density, surface area and accessible volume. It is shown that both methane and carbon dioxide adsorb via physisorption only in the modelled materials. Adsorption isotherms and energies at 300 K for pressures up to 100 bar were generated via molecular simulation. The maximum gravimetric capacity of CH4 is 16.9 wt%, occurring at 300 K and 97 bar. The maximum gravimetric capacity of CO2 is 50.3 wt%, occurring at 300 K and 51.6 bar. The best performing adsorbent was a low-density (high accessible volume) material with no –OTiCl3 groups. The presence of –OTiCl3 did not enhance physisorption even on a volumetric basis, and the high molecular weight of –OTiCl3 groups is a significant penalty on a gravimetric basis. Based on the pair correlation functions, the most favourable adsorption sites for both adsorbates are located in front of the faces of spherosilicate cubes. The self-diffusivity and activation energy for diffusion are also reported.

description: IS professionals are primarily concerned with the development of a project to meet the goals of a client. Unfortunately, IS professional do not always pay close attention to the contract or to its management and are often unaware of the legal implications of the contracts to which they are assenting. Legal advice can be sought during pre-contractual processes to help ensure that the contract meets the expectations of all the parties. If the project does not meet stakeholder's expectations, thus causing a contract to come into dispute, lawyers may be called in to review the contract and to seek a settlement. This paper reports an exploratory study of the differences in perceptions of IS development contracts that exist between IS professionals and legal practitioners.

Performance Evaluation of Machine Learning Algorithms for Detection of SYN Flood Attack: The case of ethio telecom
Creators: name: Wassihun, Beyene
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020

description: Telecom service providers operate and control complex network infrastructure used for data transmission. However, security issues have been among the most serious problems for service providers in general and ethio telecom in particularly. One of the main security problems that become the hardest and most serious threat is called Distributed Denial of Service (DDoS) attacks specifically Synchronize (SYN) flood attack. Nowadays, different researchers to detect and prevent SYN flood attack recommended several statistical detection methods. However, due to the dynamic behavior of attack has been challenged to detect using existing detection approaches. This research focused on the performance evaluation classification machine learning (ML) algorithms for detection SYN flood attack. The classification models trained and tested with packet captured (PCAP) dataset has been used and gathered from ethio telecom network by generated and captured using Hping3 and Wireshark tools respectively. This dataset has been further preprocessed and evaluated using four classification ML algorithms and three training approaches. The implementation has been performed using WEKA (Waikato Environment for Knowledge Analysis) data mining tool. The experimental results show J48 algorithm performs with 98.57% of accuracy and AdaBoost, Naïve Bayes and ANN algorithms with 98.52%, 95.31% and 94.85% of accuracy respectively. The first reason was that the J48 algorithm is more efficient than the other algorithms; it has been used as a pruning technique in order to reduce the complexity of the final classifier and to prevent over fitting the data. The second reason was the ability to learn mechanisms. Therefore, based on the performance evaluation result model with J48 algorithm has been recommended for SYN attack detection.

Creators: name: Wubshet, Abebe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Due to the growth in the network usage, there is huge traffic pressure to server clusters in the datacenters. To manage incoming traffic, operators choose a load balancing technology to assign the incoming traffic to server clusters. However, this classical load balancing technology has complexity and challenge in scalability, flexibility and manageability. But, the emerging software defined networking having application, control and infrastructure layers offers an advantage of low cost, scalable, programmable and easy management to server clusters load balancing activity by abstracting the low level functionality of the network. This study evaluates the performance of round robin, weighted round robin and least load server cluster load balancing algorithms using software defined networking open Flow model by providing ethio telecom's enterprise shop customers relation Management system users' data as input in order to answer a research question of which load balancing algorithms is better in terms of network performance parameters such as response time, transaction per second, throughput in SDN platform. Simulation has been used as a methodology to evaluate server load balancing algorithms using Open Flow model by creating a virtual environment with oracle virtual box. In addition, mininet simulation tool has used to create the network topology and POX controller used in the control layer of the open Flow model to do the performance evaluation of the load balancing algorithms. The simulation result shows that round robin algorithm is better than weighted round robin and least load server load balancing algorithms interms of response time (sec), transaction rate (trans/sec), throughput (MB/sec).

description: Wheelchair cushion is routinely used to manage the sitting acquired pressure for an individual with spinal cord injury, but which kind of wheelchair cushion performs better in terms of interface pressure management is unclear. This review aims to compare different kinds of wheelchair cushions on their effect of interface pressure reduction in individuals with spinal cord injury. The databases of MEDLINE, CINAHL, EMBASE and Web of Science were searched. Totally 10 studies were included in this review. Seven of the included studies indicated that air cushions were superior to gel cushions in interface pressure reduction. Three of the included studies reported that gel cushions were superior to polyurethane foam cushions in interface pressure reduction. The variables of measurement duration, measurement focus, measurement devices, cushion covering, sample variations and body positioning of patients may confound the comparison of interface pressure reduction effect of different wheelchair cushions among studies. Air cushion was reported more consistently effective in interface pressure reduction than gel and foam cushions. While the variable parameters (measurement duration, focus, devices) and individual conditions (BMI, body positioning) may interfere the comparison among studies. Researches disseminating consistent parameters and clinical prescriptions with individualized evaluation are suggested for the establishment of an evidence-based practice in clinic.Implications for rehabilitationWheelchair cushion is routinely used for an individual post spinal cord injury to manage the sitting acquired pressure.Which kind of wheelchair cushion performs better in terms of interface pressure management is unclear.Air cushion is found more consistently effective in interface pressure reduction than gel cushion and foam cushion.Individualized evaluation of the interface pressure is suggested for the prescription of wheelchair cushion in clinic.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020

description: This thesis develops a model to detect cell outage on real ethio telecom network data by using density based anomaly detection algorithms through the application of machine learning technique. Cell outage is the total/partial loss of radio network in a given area and the process of detecting cell outage is called cell outage detection. Cross-Industry Standard Process (CRISPDM) machine learning methodology, which is a six staged open standard process model that describes common approaches for data mining or machine learning was used. The considered data was normal and problematic network environment obtained from ethio telecom UMTS network in Addis Ababa. The proposed detection framework used network performance data (incoming handover (inHO), which is the process of transferring an ongoing call from one cell to the other, and traffic data, originated from base station and terminated to mobile device) of the neighbor cells to capture the normal network state and to detect the outage of the target cell automatically in a pre-set time interval in the UMTS network environment. To profile the normal network operation, the study used two density based anomaly detection algorithms; namely, the K- Nearest Neighbor (K-NN) and Local Outlier Factor (LOF) algorithms, of which one was selected based on its performance during the training. To validate the models, K-fold cross validation technique was used and for the selection of the optimal model, parameter selection was done for different values of K (K=1,2, 3…30). To compare the two algorithms, Receiver Operating Characteristic (ROC) curves were used. Based on the results, the K-NNAD was found to be of a better performance than the LOFAD, thus was selected as a detector in the profiling stage. The proof of the system model was tested by using real problematic network state data and the results of classic data mining metrics were obtained. Based on the results obtained from the testing, the K-NNAD method was found to perform better in detecting outage cells in the proposed framework.

description: After the occurrence and detection of a short circuit to ground in the LHC main dipole circuit, a fast power abort is triggered and the current in the circuit starts decaying semi-exponentially from a maximum value of 11.85 kA to zero, with a time constant of 103 s. If a short to ground occurs, the current flows through the fuse that is present in the grounding subcircuit. Depending on the value of the thermal load, the fuse first enters a pre-arcing region where it starts intermittently blowing up, until the blow-up threshold is reached, after which it definitively blows up. A simulation scheme utilising a common interface between PSpice and Matlab is proposed in order to simulate the blow-up behaviour of the fuse and hence increase the accuracy of the circuit model for short circuits to ground. A parametric analysis of the short circuit to ground parameters is performed and a better understanding of the behaviour of the circuit under different conditions is obtained. The worst-case values of the voltage to ground in the LHC main dipole circuit are identified for both the case where the intermittent behaviour of the fuse is included in the model as well as for the case where the fuse is not modelled and a comparison between the two is given.

UMTS Network Coverage Hole Detection using Decision Tree Classifier Machine Learning Approach
Creators: name: Geleta, Abdissa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2020

description: Due to various innovative mobile services and applications, traffic is constantly increasing in size and complexity globally and as well as locally in Ethiopia. To fulfill these requirements in both quality and quantity, a wide range of radio frequency signal coverage areas are required. One means of satisfying this requirement is proper planning and devising proper network management during operational phase for network coverage hole detection for optimization of uncovered area. Measurement collection is a primary step towards analyzing and optimizing the performance of a telecommunication service. In this sense, this work aims to present a solution that contributes to reduce costs and time in network monitoring by exploiting user equipment Measurement Report (MR) data via the Minimization of Drive Tests (MDT) functionality. An automatic coverage hole detection based on classification techniques, which is a Decision Tree (DT) classifier-based approach is used for rule induction to identify different scenarios of coverage holes and their respective areas for better service delivery purposes. The main idea is to jointly observe signal strength and signal quality for effective coverage-hole detection. It uses a new approach to classify four coverage scenarios such as "good coverage and good quality", "good coverage but poor quality", "poor coverage but good quality", and "poor coverage and poor quality" in Universal Mobile Telecommunications System (UMTS) network considering the last three coverage classes as coverage -hole with different severity levels. The result showed that the applied model accuracy was 99.98%, and also the proposed approach could classify the target classes and allows the visualization of network performance in terms of signal strength and quality associated with a location. All four coverage scenarios were visibly observed and the results are almost uniform with validation results found from the driving test (with about 7dB and 1dB difference of RSCP and Ec/No respectively considering the cumulative distribution function value of 18%). 77% of coverage areas were classified as good coverage condition.

description: Muss in Zeiten der Pandemie der Deutsche Bundestag auf ein Notparlament zusammenschrumpfen können? Bundestagspräsident Schäuble fordert das. Dabei gibt es bessere und weniger demokratieschädlichere Möglichkeiten, etwa die der Zuschaltmöglichkeit für Abgeordnete in Quarantäne zur Plenardebatte, die das Problem genauso lösen. Darüber diskutiert Max Steinbeis mit ANNA VON NOTZ in der heutigen Folge unseres Krisen-Podcasts.

description: This article presents a novel open source toolbox for street network comparison based on the Sextante geoprocessing framework for the open source Geographic Information System Quantum GIS (QGIS). In the spirit of open science, the toolbox enables researchers worldwide to assess the quality of street networks such as OpenStreetMap (OSM) by calculating key performance indicators commonly used in street network comparison studies. Additionally, we suggest two new performance indicators for turn restriction and one-way street comparisons specifically aimed at testing street network quality for routing. We demonstrate the use of this toolbox by comparing OSM and the official Austrian reference graph “Graph Integration Platform” (GIP) in the greater Vienna region.

description: We examined the effects of electrostatic interactions on gas adsorption and permeability of metal organic framework (MOF) membranes and MOF-filled mixed matrix membranes (MMMs) for CO2/CH4, CO2/N2 and H2/CO2 separations using molecular simulations. Adsorption isotherms and diffusion rates of CO2, CH4, N2 and H2 in several MOFs were computed using grand canonical Monte Carlo and equilibrium molecular dynamics simulations, respectively. Gas permeability and selectivity of pure MOF membranes and MOF-filled MMMs were then evaluated using theoretical permeation models. The accuracy of our molecular simulations was validated by comparing theoretical predictions for gas permeability and selectivity of MOF-filled MMMs with the available experimental data. We then used the same modelling approach to predict the performance of new MOF-filled MMMs in CO2/CH4, CO2/N2 and H2/CO2 separations. Promising MOF/polymer combinations which offer high selectivity and permeability relative to pure polymer membranes were identified. Our results showed that including electrostatic interactions between adsorbate molecules and MOF atoms is crucial for modelling pure MOF membranes but has less significance for modelling MOF-filled MMMs whenever the MOF volume fraction, ≤ 0.30. This result suggests that preliminary screening studies of MOF-filled MMMs can be carried out without assigning partial charges to MOF atoms.

description: The adsorptive and diffusive behaviour of methane and carbon dioxide in amorphous nanoporous adsorbents composed of spherosilicate building blocks, in which isolated metal sites have been distributed, is examined. The adsorbent contains cubic silicate building blocks (spherosilicate units: Si8O20), which are cross linked by SiCl2O2 bridges and decorated with either –OTiCl3 or –OSiMe3 groups of the other cube corners. The model structures were generated to correspond to experimentally synthesised materials, matching physical properties including density, surface area and accessible volume. It is shown that both methane and carbon dioxide adsorb via physisorption only in the modelled materials. Adsorption isotherms and energies at 300 K for pressures up to 100 bar were generated via molecular simulation. The maximum gravimetric capacity of CH4 is 16.9 wt%, occurring at 300 K and 97 bar. The maximum gravimetric capacity of CO2 is 50.3 wt%, occurring at 300 K and 51.6 bar. The best performing adsorbent was a low-density (high accessible volume) material with no –OTiCl3 groups. The presence of –OTiCl3 did not enhance physisorption even on a volumetric basis, and the high molecular weight of –OTiCl3 groups is a significant penalty on a gravimetric basis. Based on the pair correlation functions, the most favourable adsorption sites for both adsorbates are located in front of the faces of spherosilicate cubes. The self-diffusivity and activation energy for diffusion are also reported.
Una riflessione interdisciplinare sulle monete altre. Il caso studio dei Chipicos in Argentina

description: Questo articolo si inserisce nel filone di studi che ripensano la questione della moneta attraverso una prospettiva multidisciplinare, riconosciuta come fondamentale per comprendere le sperimentazioni monetarie contemporanee e, in effetti, la natura stessa della moneta. Collegandoci alla proposta di Gómez e Dini (2016), utilizziamo i dati ottenuti da uno studio empirico su un caso situato in Argentina per contribuire alla ricerca sull’origine e sul significato della moneta. Attraverso l’analisi dei Chipicos, emessi da una cooperativa argentina, questo lavoro esplora le dinamiche sociali ed economiche emergenti, considerando anche le interconnessioni tra circolazione monetaria e riproduzione sociale. Inoltre, si indaga la questione sociologica dell’ontologia monetaria in relazione ai valori e alla moneta. L’analisi rivela come le monete alternative possano influenzare le relazioni sociali e offrire una prospettiva critica sulle teorie monetarie esistenti, arricchendo il dibattito accademico con contributi da filosofia, antropologia e sociologia.

description: A self-assembled sensor based on a boron-doped diamond was investigated as a sensitive tool for voltammetric analysis of a member of a pyridine herbicide family - picloram. A cyclic voltammetry and a differential pulse voltammetry were applied for investigation of the voltammetric behaviour and quantification of this herbicide. Picloram yielded one well-developed irreversible oxidation signal at a very positive potential about +1.5 V vs. Ag/AgCl/3 mol L−1 KCl electrode in an acidic medium and 1 mol L−1 H2SO4 was chosen as a suitable supporting electrolyte. Operating parameters of differential pulse voltammetry were optimized and the proposed voltammetric method provided a high repeatability (a relative standard deviation of 20 repeated measurements at a concentration level of picloram of 50 µmol L−1 equaled to 2.58%), a linear concentration range from 2.5 to 90.9 µmol L−1 and a low limit of detection (LD = 1.64 µmol L−1). Practical usefulness of the ‘environmentally-green’ electrochemical sensor was verified by an analysis of spiked water samples with satisfactory recoveries.
