Software Defined Network Based VANET

As the number of cars is growing, there is also a rapid growth in the number of road side accident. Much of these incidents have occurred by an error made by a driver. New protocols and architecture are rapidly being created for intelligent transport networks by researchers all over the world. To guarantee passengers’ safety, several companies are now encouraging an ad hoc vehicular network (VANET). In another side, before practically adopting VANET technology, there are many concerns related to this field that need to be discussed. A number of attacks can occur in the event of no or weak protection, which can be affected by the performance and reliability of the process. In order to make VANET networks more successful, it implements software defined networking (SDN) technology. This technique was briefly called SDN-VANET. The SDN in VANET framework enables us to prevent from the limitations and complexities of basic VANET structures. Through handling the whole network from a single remote controller, it allows them to reduce the overall burden on the network. In this article we describe SDN-based VANET, its working, benefits, challenges and services, applications, and security attacks.
MIPAS monthly zonal mean Age of Air data, based on MIPAS SF6 retrievals, processed at KIT-IMK, Karlsruhe

Aus den Infrarotspektren der Jahre 2002-2012 des Satelliteninstrumentes MIPAS wurde die raumliche und zeitliche Verteilung von SF6 berechnet. Daraus wurden zonale Monatsmittelwerte des Luftalters (Age of Air) in 30 jeweils 6 Grad umfassenden Breitenbereichen bestimmt. Die Berechnung des Luftalters ist beschrieben in Haenel et al. (2015) [https://doi.org/10.5194/acp-15-13161-2015], die SF6-Daten fur den vorliegenden Datensatz (Versionen V5H_SF6_21 und V5R_SF6_224/225) wurden jedoch berechnet mit den neueren Spektroskopiedaten fur SF6 und CFC-11 von J.J.Harrison (2018,2020) [https://doi.org/10.5194/amt-11-5827-2018, https://doi.org/10.1016/j.jqsrt. 2020.107202].
3D thermo-hydro-mechanical coupled discrete beam lattice model of saturated poro-plastic medium

In this paper, we present a 3D thermo-hydro-mechanical coupled discrete beam lattice model of structure built of the nonisothermal saturated poro-plastic medium subjected to mechanical loads and nonstationary heat transfer conditions. The proposed model is based on Voronoi cell representation of the domain with cohesive links represented as inelastic Timoshenko beam finite elements enhanced with additional kinematics in terms of embedded strong discontinuities in axial and both transverse directions. The enhanced Timoshenko beam finite element is capable of modeling crack formation in mode I, mode II and mode III. Mode I relates to crack opening, mode II relates to in-plane crack sliding, and mode III relates to the out-of-plane shear sliding. The pore fluid flow and heat flow in the proposed model are governed by Darcy\'s law and Fourier\'s law for heat conduction, respectively. The pore pressure field and temperature field are approximated with linear tetrahedral finite elements. By exploiting nodal point quadrature rule for numerical integration on tetrahedral finite elements and duality property between Voronoi diagram and Delaunay tetrahedralization, the numerical implementation of the coupling results with additional pore pressure and temperature degrees of freedom placed at each node of a Timoshenko beam finite element. The results of several numerical simulations are presented and discussed.
The Relationship Between Indirect Aggression and Loneliness for Emerging Adults: What Does Interpersonal Competence Have to Do with Wellbeing?

The present study investigated the mediating role of interpersonal competence in the relationship between indirect aggression and loneliness for emerging adults. One hundred and sixty-seven Canadian undergraduate students aged 18-25 participated and completed an anonymous, online survey. Structural equation modeling was used to analyze the mediating role of interpersonal competence in the relationship between indirect aggression and loneliness. The findings revealed that interpersonal competence mediated the relationship between indirect aggression for targets and loneliness. These findings have implications for mental health researchers and practitioners and can inform the development of prevention and intervention programs for young adults dealing with indirect aggression. Keywords: indirect aggression, emerging adults, interpersonal competence, loneliness, psychosocial functioning La présente étude porte sur le rôle de médiation de la compétence interpersonnelle dans le lien entre l’agression indirecte et le sentiment de solitude chez les adultes émergents.

Anti-windup Design for Satellite Control with Microthrusters

Future space missions (e.g. microscope, formation flying, rendez-vous) demand for an acceleration or relative position control. That requires actuators that can provide an effort in the linear axis. Therefore propulsion systems apply. Then, these same systems are used for the attitude control instead of the reaction wheels. At the same time a high precision is demanded. Thus microthrusters are needed as they are able to perform an almostcontinuous propulsion, between zero and its maximum, with a quantization. Even though they satisfy the demands on high precision, the maximal propulsion capacity appears to be critically low, which could lead to the saturation of the actuator. A model of the systems needing longitudinal efforts with high precision is presented. Microthrusters used in these kind of systems are also characterized. An anti-windup controller design technique is proposed for this kind of actuators. Simulations consider the attitude control of an axis of a satellite. They show how the anti-windup controller increases the level of saturation allowed as well as the disturbance amplitude. Simulations are based on a nominal model provided by CNES and developed in matlab/simulink.
Assessing Performance of Small‐Scale Pumped Irrigation Systems in sub‐Saharan Africa: Evidence from a Systematic Review

Small‐scale irrigation (SSI) has significant potential to increase crop productivity in sub‐Saharan Africa (SSA). Pumped irrigation systems are one of the technologies increasingly being used by smallholder farmers. The aim of this study was to systematically review evidence on the performance of SSI pumped systems, including motorized, treadle, rope and washer, solar and wind pumps. The study revealed a lack of standardization and use of a wide range of indicators to assess performance. Most evidence related to motorized pumps, and these studies confirmed mixed levels of performance; studies relating to other types of pumped system mostly reported a positive impact, although the method of assessment used was critical. Studies reporting positive impacts tended to be those that used socio‐economic based factors such as yield and profitability, whereas studies reporting mixed performance tended to be those that relied more on technically based indicators such as pumping and irrigation system efficiency. The analysis highlights the sensitivity of interpreting findings from different studies, and how caution should be exercised when comparing performance within and between different types of irrigation systems. The implications for supporting policy development and identifying future research gaps are discussed. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.
NLMaps Web: A natural language interface to OpenStreetMap

This abstract was accepted to the Academic Track of the State of the Map 2021 Conference after peer-review. Nominatim [1] and Overpass [2] are powerful ways of querying OSM, but the Overpass Query Language is somewhat impractical for quick queries for unfamiliar users. In order to query OSM using natural language (NL) queries such as “Show me where I can ﬁnd drinking water within 500m of the Louvre in Paris”, Lawrence and Riezler [3] created the ﬁrst NLMaps dataset mapping NL queries to a custom machine-readable language (MRL), which can then be used to retrieve the answer from OSM via a combination of queries to Nominatim and Overpass. They extended their dataset in a subsequent work by auto-generating synthetic queries from a table mapping NL terms to OSM tags – calling the combined dataset NLMaps v2. [4] The proposed purpose of these datasets is training a parser that can parse NL queries into their MRL representation, as done in [4–7]. The main aim of this work was to build a web-based NLMaps interface that can be used to issue queries and to view the result. In addition, the web interface should enable the user to give feedback on the returned, either by simply marking the parser-produced MRL query as correct or incorrect, or by explicitly correcting it with the help of a web form. This feedback should be directly used to improve the parser by training it in an asynchronous online learning procedure.
Position and Orientation Measurement of Parallel Robot Based on Monocular Vision

： The robot pose errors detection is a key step to realize the kinematic calibration. The six-dimensional geometrical errors detection using a single CCD camera and elaborately designed targets is proposed. A model of rigid body displacement and its 2D image mapping, which is constructed based on 4 spatial features and 2 vanishing points of a parallelogram geometric constraint, can be used to achieve precise positioning of the position and pose of the end-effector. By taking a Delta robot as a demonstrator, experiments of kinematic calibration will be carried out to verify the validity and effectiveness of the proposed approach. The outcomes will lay a solid theoretical foundation for the low-cost and fast kinematic calibration of the robot.
3D Objects Grasps Synthesis: A Survey

This survey reviews computational algo- rithms for generating 3D objects grasps with autonomous multi-fingered robotic hands. Over the past 20 years, grasping has been an increasingly active research area. Ex- isting papers focus on reviewing the mechanics of grasping and the finger-object contacts interactions (21) or robot hand design and their control (4). Robot grasp synthesis algorithms has been reviewed in (17), but since then an im- portant progress has been made toward applying learning techniques to the grasping problem. This survey focuses on analytical as well as empirical grasp synthesis approaches.
Analyse von Entwurfsentscheidungen in natürlichsprachiger Softwarearchitekturdokumentation

Entwurfsentscheidungen bilden das Fundament zur Entwicklung qualitativ hochwertiger Softwaresysteme. Ihre Extraktion aus und Klassifikation in naturlichsprachiger Softwaredokumentation ermoglichen die Informationsgewinnung fur Implementierungsund Wartungsprozesse und die Erstellung konsistenter Dokumentationsartefakte. Das in dieser Arbeit entwickelte Klassifikationsschema fur Entwurfsentscheidungen erweitert bestehende Ansatze, die zwar in der Lage sind, Entwurfsentscheidungen in ihrer Breite zu klassifizieren, jedoch keine klar umrissenen Klassen fur die Klassifikation in der hierarchischen Tiefe festlegen. Die hier entwickelten Klassen versuchen, die verschiedenen Arten von Entwurfsentscheidungen vollstandig abzubilden. Die dazwischenliegenden, feingranulareren Trennlinien dienen dazu, die Entwurfsentscheidungen deutlicher voneinander abzugrenzen. Nachdem zunachst ein initiales Klassifikationsschema entworfen wird, wird in einem iterativen Prozess die Passform des Klassifikationsschemas durch die Anwendung auf die reale Softwarearchitekturdokumentation von 17 Fallstudien validiert und verbessert, bis hin zur Konvergenz auf ein ausgereiftes Schema. Neben einer Ubersicht, welche Entwurfsentscheidungen getroffen und dokumentiert werden, liefert die manuelle Analyse der Fallstudien einen mit Labeln versehenen Textkorpus. In einem zweiten Teil wird eine Anwendungsmoglichkeit des entwickelten Klassifikationsschemas eroffnet, indem in einer Proof-of-Concept-Implementierung untersucht wird, mit welchen Ansatzen des maschinellen Lernens und der naturlichen Sprachverarbeitung Entwurfsentscheidungen in naturlichsprachiger Softwarearchitekturdokumentation identifiziert und klassifiziert werden konnen. Durch die Evaluation mit statistischen Masen wird gezeigt, welche Methoden zur Textvorverarbeitung, zur Uberfuhrung in Vektorreprasentationen und welche Lernalgorithmen besonders fur diese Klassifikation geeignet sind. Die automatisierte Ruckgewinnung von Entwurfsentscheidungen aus der Dokumentation und gleichzeitige Zuordnung zu Kategorien mit gemeinsamen Eigenschaften erleichtert Aspekte im Softwareentwicklungsprozess wie Verstandlichkeit, Konsistenz und Wartbarkeit.
Exploring how the national COVID-19 pandemic policy and its application exposed the fault lines of educational inequality

In the wake of Covid-19, a flurry of surveys in education were conducted. These revealed alarming statistics about most learners losing half of the academic year, parents’ angst about sending children to school, and a small fraction of higher education institutions being able to leverage affordances of technology for effective online teaching and learning. As our right to breathe, eat and learn became suffocated, we were urged to re-imagine possibilities for resurrection, for mitigating current and future education “losses”. Deafened by the varied cacophony from teacher and student unions, school governing body representatives, scientists and education experts, the government with its departments of education decided to close education institutions and this coincided with the hard lockdown. Against this background, we use the lens of critical policy analysis (CPA), to explore the decision-making of education departments. In this qualitative study, a critical lens was used to reveal the magnification of the fault lines of educational iniquity and inequity as departments of education made decisions to close and reopen institutions. Multiple data generation methods included a key informant interview with a senior official from the Department of Education, a survey among school personnel, and document analysis. The findings revealed a tension between expectations of producers of policy and recipients of policy, within unequal school settings. A repositioning, by peering through the lens of the dispossessed to inform future policy, is recommended.
Auditor Switching and Abnormal Returns

The main factor that every investor pays special attention to in his decisions is a return. What is important for users of financial information is not the procedures and principles used in accounting, but the exit from the financial system, because it helps them achieve their goals. Many capital market concerns focus on accounting and auditing operations. Therefore, the independence of the auditor is the basis of public trust in the audit process and the assurance of auditors` reports. For this purpose, the purpose of this study is to investigate the effect of auditor switching on abnormal returns. Therefore, three hypotheses have been formulated and a sample consisting of 365 companies listed on the Tehran Stock Exchange during the years 2010 to 2020 has been selected. The results indicate that lateral auditor switching has no significant effect on abnormal returns. Also, between the CU switch and CD switch, the CD switch has a negative and significant effect on abnormal returns.
SYNTHESIS AND FUNCTIONALIZATION OF THE PYRAZOLO [3,4-b]PYRIDIN-3-ONES RESEARCH OF THE SEROTONINERGIC ACTIVITY

A convenient route to the synthesis of pyrazolo[3,4-b]pyridin-3-ones via condensation of 3- amino-1-phenylpyrazolin-5-one with 4-hydroxy-6-methylpyran-2-one. The isomeric pyrazolo[3,4-b]pyridin-3-ones obtained are functionalized in position 4 or 6 by aliphatic and aromatic amines, on the other hand position 1 of another derivative pyrazolopyridinic was functionalized by a synthetic grouping. The serotoninergic activity of the various compounds obtained was also examined and discussed.
Rail vehicle localization exploiting rail track georeferenced coordinates

A dead reckoning algorithm especially conceived for localization of rail vehicles in GNSS-denied environments is presented. The vehicle’s three-dimensional position is computed through one-dimensional measurements, given by incremental encoders attached to the wheels, combined with railroad models, obtained from georeferenced track coordinates. Given that the platform may travel along several kilometers and considering that dead reckoning techniques accumulate errors over time leading to increasing global uncertainty, a method was designed to correct the estimates and also smooth trajectory errors backwards in time, through visualization of global landmarks along the way. The current document reports real railroad experiments, featuring a specially designed non-motorized mobile modeling vehicle.
MHD Mixed Convective Heat Transfer of a Micropolar Fluid Over an Unsteady Stretching Porous Wedge with Viscous Dissipation and Joule Heating

This study investigate numerically heat and mass transfer characteristics of two dimensional unsteady MHD mixed convective flow of a micropolar fluid along a stretchin permeable wedge taking into account the effects of viscous dissipation and Joule heating with convective boundary condition.The governing partial differential equations are transferred into ordinary differential equations using a set of non-dimensional variables and solve them numerically by Nachtsheim-Swigert shooting iteration technique with sixth order Runge-Kutta method. Effects of non-dimensional governing parameters on velocity, microrotation and temperature profiles are presented through graphs and discussed from physical point of view. The local skin friction coefficient, plate couple stress and the rate of heat transfer is also investigated for the different values of the pertinent parameters. The results show that both the rate of share stress and the rate of heat transfer increase with the increase of Hartmann number and Eckert number for both suction and injection cases.
Automated Generation of Construction Schedules based on the IFC Object Model

Processes in civil engineering consist of a huge amount of different tasks with complex dependencies between them. Currently, the specification and adaption of construction schedules are supported insufficiently. To provide a more efficient and comprehensible planning support, within a research project several methods and algorithms have been developed to allow semi-automatic generation of construction schedules including different construction alternatives. This allows handling and comparing construction alternatives as well as the reuse of schedules created previously. This paper introduces a novel approach for the generation of construction schedules using Industry Foundation Classes. It facilitates project managers to extract information from a building information model for scheduling and leads to a quick visualization via 4D simulations without further user interaction.
Fabrication and electrical characterization of partially metallized vias fabricated by inkjet

Through silicon vias (TSVs), acting as vertical interconnections, play an important role in micro-electro-mechanical systems (MEMS) 3D wafer level packaging. Today, taking advantage of nanoparticle inks, inkjet technologies as local filling methods could be used to plate the inside the vias with a conductive material, rather than using a current method, such as chemical vapor deposition or electrolytic growth. This could decrease the processing time, cost and waste material produced. In this work, we have fabricated and demonstrated electrical characterization of TSVs with a top diameter of 85 μm, and partially metallized on their inside walls using silver nanoparticle ink and drop-on-demand inkjet printing. Electrical measurement showed that the resistance of a single via with a void free coverage from top to bottom could be less than 4 Ω, which is still acceptable for MEMS applications.
Biofeedback: using technology to enhance the mind-body relationship in therapy

The use of technology and biofeedback to bridge the mind-body connection is not new. From the early 1960's, there have been reports of what appeared to be remarkable effects when clients or patients were connected to various complex pieces of electronic apparatus and given information about their bodies' reactions to stressful situations. However, much of what was reported during the first decade or so of biofeedback's history was alternately amazing (too much so! ), or too technically complex for the average practitioner. Although the points were gradually accumulating on the board supporting the use of biofeedback for a range of client issues from fields such as behavioural medicine (eg asthma, abnormal muscle tremor, hypertension, migraine) and the more psychological therapies (eg for obsessive- compulsive behaviour, phobias, sexual difficulties), the applicability of biofeedback for general counselling (eg anxiety, depression, relationship difficulties) has been less well known.

Removing Barriers for Effective Deployment of Intermittent Renewable Generation

The stochastic nature of intermittent renewable resources is the main barrier to effective integration of renewable generation. This problem can be studied from feeder-scale and gridscale perspectives. Two new stochastic methods are proposed to meet the feeder-scale controllable load with a hybrid renewable generation (including wind and PV) and energy storage system. For the first method, an optimization problem is developed whose objective function is the cost of the hybrid system including the cost of renewable generation and storage subject to constraints on energy storage and shifted load. A smart-grid strategy is developed to shift the load and match the renewable energy generation and controllable load. Minimizing the cost function guarantees minimum PV and wind generation installation, as well as storage capacity selection for supplying the controllable load. A confidence coefficient is allocated to each stochastic constraint which shows to what degree the constraint is satisfied. In the second method, a stochastic framework is developed for optimal sizing and reliability analysis of a hybrid power system including renewable resources (PV and wind) and energy storage system. The hybrid power system is optimally sized to satisfy the controllable load with a specified reliability level. A load-shifting strategy is added to provide more flexibility for the system and decrease the installation cost. Load shifting strategies and their potential impacts on the hybrid system reliability/cost analysis are evaluated trough different scenarios. Using a compromisesolution method, the best compromise between the reliability and cost will be realized for the hybrid system.
