When Learning Analytics Meets MOOCs - a Review on iMooX Case Studies
Abstract
The field of Learning Analytics has proven to provide various solutions to online educational environments. Massive Open Online Courses (MOOCs) are considered as one of the most emerging online environments. Its substantial growth attracts researchers from the analytics field to examine the rich repositories of data they provide. The present paper contributes with a brief literature review in both prominent fields. Further, the authors overview their developed Learning Analytics application and show the potential of Learning Analytics in tracking students of MOOCs using empirical data from iMooX.

The Offline Map Matching Problem and its Efficient Solution
Abstract
In this paper we present an efficient solution to the offline map matching problem that occurs in the area of position measurements on a road network: given a set of measured positions, what was the most probable trip that led to these measurements? For this, we assume a user who moves according a certain degree of optimality across a road network. A solution has to face certain problems; most important: as a single measurement may be mapped to multiple positions on the road network, the total number of combination exceeds any reasonable limit.

Using Data as Observers: A New Paradigm for Prototypes Selection
Abstract
The prototype selection is a bottleneck for lot of data analysis procedures. This paper proposes a new deterministic selection of prototypes based on a pairwise comparison between data. Data is ranked relative to each data. We use the paradigm of the observer situated on the data. The ranks relative to this data gives the viewpoint of the observer to the dataset. Two observers provide a link between them if they have no data between them from their respective viewpoints. The links are directed to obtain a directed graph where data is the set of vertices of the graph. The observers move using the directed graph. They reach a prototype when they arrive at a viewpoint with no outgoing connexion of the directed graph. This method proposes both the prototype selection and the structuration of the dataset through the directed graph. The paper also presents an assessment with three kinds of datasets. The method seems particularly useful when the classes are hardly distinguishable with classical clustering methods.

Monitoring and Decision Making

Reconstruct Underground Infrastructure Networks Based on Uncertain Information
Abstract
This paper focuses on developing methods to reconstruct the physical path of underground infrastructure networks. These reconstructions are based on the structure of the network, start and endpoints and the structure of an underlying network. This data is partly considered unreliable or uncertain. Two methods are presented to realise the reconstruction. The first method finds a path of given length in a directed graph by applying a modified version of Yen’s algorithm for finding K-shortest simple paths in a directed graph. A second, so-called Bottom-up approach is developed which aims to take advantage of the structure of the underlying network. The developed methods are applied on a series of examples for comparison.

Design and Realization of Mobile Environmental Inspection and Monitoring Support System
Abstract
If as mobile devices are introduced and cutting-edge information and communication technology (ICT) is developed, the need for mobile service at environmental inspection and monitoring work task sites in environmental contaminant discharging facilities is increasing. In this study, a hybrid app combining the mobile application technology and the mobile web technology was developed based on the environmental guidance and examination procedures, the analysis of the relevant laws and systems, and the results of the interview and questionnaire survey performed with relevant public officers. It uses Android and iOS which are the operating systems widely used in Korea. Considering the characteristics of the environmental guidance and examination procedures, the developed application provides information about the physical state or performance of environmental contaminant discharging facilities and the relevant authorities. To meet the required efficiency at the worksite and to provide optimized system functions, an actual application and operation test was performed by establishing a test-bed.

Re-visited: On the Value of Purely Software-Based Code Attestation for Embedded Devices
Abstract
Remote code attestation protocols are an essential building block to offer a reasonable system security for wireless embedded devices. In the work at hand we investigate in detail the trustability of a purely software-based remote code attestation based inference mechanism over the wireless when e.g. running the prominent protocol derivate SoftWare-based ATTestation for Embedded Devices (SWATT). Besides the disclosure of pitfalls of such a protocol class we also point out good parameter choices which allow at least a meaningful plausibility check with a balanced false positive and false negative ratio.

Secure Whitelisting of Instant Messages
Abstract
Nowadays, social networks (like Facebook) have not only absorbed the function of abating pure IM (Instant Messaging) systems (like ICQ) but also their dangers, such as cyberbullying and security violations. Existent safe IM blacklist sifters already conform to the security objectives authenticity, integrity, privacy, and resilience, but simple tricks of inventive bullies can evade filtering of their originated instant messages. Therefore, this treatise introduces a novel conception of a secure IM sieve based on whitelisting. Beside a detailed view on the underlying architecture, security and performance analyses adumbrate the feasibility of the approach.

Collaboration and Workflow

Adaptive Workflow System Concept for Scientific Project Collaboration
Abstract
Scientific projects are dynamic processes, and possibilities to determine their structure beforehand is matter of great practical importance. Some communities that work on the same project can join scientists from various countries and research centers. The approaches related to BPM (Business Process Management) are rigid and are “process–centric”, therefore they provide limited flexibility for some of process handling requirements. ACM (Advanced Case Management), in contrary, provides the necessary degree of flexibility. Moreover its synthesis with the BPM suggested attractive advantages for process configuration and control.
In this paper we propose a concept of adaptive workflow system for scientific project collaboration and introduce the description of each part in detail. A user describes a project in terms of cases. Then system suggests suitable possible process models, that the user is free to follow or not. At further steps the system specifies its suggestions. This approach combines the flexibility of ACM with clearness of BPM.

Zebras and Lions: Better Incident Handling Through Improved Cooperation
Abstract
The ability to appropriately prepare for, and respond to, information security incidents, is of paramount importance, as it is impossible to prevent all possible incidents from occurring. Current trends show that the power and automation industry is an attractive target for hackers. A main challenge for this industry to overcome is the differences regarding culture and traditions, knowledge and communication, between Information and Communication Technology (ICT) staff and industrial control system staff. Communication is necessary for knowledge transfer, which in turn is necessary to learn from previous incidents in order to improve the incident handling process. This article reports on interviews with representatives from large electricity distribution service operators, and highlights challenges and opportunities for computer security incident handling in the industrial control system space.

Routing over VANET in Urban Environments
Abstract
Experimental deployment of Cooperative Intelligent Transport Systems have been undertaken these last years. But a real deployment is lower than expected. One of the main reasons is the high cost of investments of Road Side Units on roads. Road operators need a lot of money in order to achieve this deployment. We suggest to reduce this investment by the deployment In this paper, we propose a combination of GPSR (Greedy Perimeter Stateless Routing) and an extension of Reactive Location Service denoted eRLS. They used to be combined, i.e. GPRS takes care of routing packets from a source to a destination and eRLS is called to get the destination position when the target node position is unknown or is not fresh enough. When a destination is not in the area of the sender, the exact position of the target is first looked for. An extra overhead is generated from the sender to the receiver since t is quite complicated to have an efficient Location System service as RLS. In the meantime, in deployed Cooperative Intelligent Transport Systems (C-ITS), fixed components are usually installed and denoted road side units (RSUs). In this paper we suggest to use these fixed RSUs to achieve the location service.
When a sender needs to send a packet, it first looks for the next RSU and sends the packet to it This RSU is connected to all other RSUs using a wired network. The aim is to find the nearest RSU to the destination. It is done thanks to a request on all RSUs Then the packet is forwarded to it. The last step is to look for the target node in the area of this last RSU. Even if the node has moved, we will have more chances to reach the node in this area.
Experimentations of our proposes solution have been done over the NS-3 simulator where an extension of RLS is developed and included on the simulator. The obtained results have shown a better accuracy vehicle locations and better performances in terms of delay.

Tech4SocialChange: Technology for All
Abstract
Universities and other educational institutions are sometimes accused of not being involved in real world problems, focusing more on the scientifically value of the work produced and not on the humanitarian value. A way of encapsulating the second with the first is the main goal of the Tech4SocialChange that is described here. An innovative database/repository of challenges with real impact in the world is created and given access to people with skills and knowledge to tackle them. Also the work made by researches can be stored and used in a project and the researcher gets recognition for it by becoming referenced in that project. A web application has been built as a prototype for this process and can be accessed in www.​tech4socialchang​e.​org. It has been planned and developed by a team of students and researchers of the Department of Informatics Engineering of the University of Coimbra and is currently being constantly altered according to feedback received by the testers in the same team. This paper presents an application that aims to help people that face certain challenges every day and motivate those that have the skillset, to tackle these challenges, into doing so.

Topic and Object Tracking

Topic Tracking in News Streams Using Latent Factor Models
Abstract
The increasing number of published news articles and messages in social media make it hard for users to find the relevant information and to track interesting topics. Relevant news is hidden in a haystack of irrelevant data. Text-mining techniques have been developed to extract implicit, hidden information. These techniques analyze big datasets and compute “latent” features based on implicit correlations between documents and events. In this paper we develop a system that applies latent factor models on data streams. Our method allows us detecting the dominant topics and tracking the changes in the relevant topics. In addition, we explain how the extracted knowledge is used for computing recommendations based on trending topics and terms. We evaluate our system on a stream of news messages published on the micro-blogging service Twitter. The evaluation shows that our system efficiently extracts topics and provides valuable insights into the continuously changing news stream helping users quickly identifying the most relevant information as well as current trends.

Collaboration Support for Transport in the Retail Supply Chain
A User-Centered Design Study
Abstract
The purpose of this paper is twofold. First, we describe a user-centered design process for finding functional requirements for holistic control panels supporting better collaboration and coordination between transport operations and supply chain processes affected by or affecting the transport of goods. Secondly, we present the resulting functionality as seen from the perspective of different actors in the supply chain, from producer to shop. One of the largest retailers in Norway is used as a case.
The case study and the user-centered approach are performed with several elicitation methods such as observations, interviews, innovation games and paper prototyping. The suggested solutions are expressed by means of paper prototypes which have been co-created and validated by the stakeholders in the supply chain during an iterative incremental process.
Currently, solely central experts in the organisations involved are able to solve problems by combining information from many sources and by taking the right actions. Due to the identified need for more robust and automated solutions, the paper prototypes suggest unified solutions that (1) provide easy and automated access to the right information at the right time for all actors in the supply chain; (2) supports easy detection of deviations; and (3) supports decisions that can improve efficiency and deviation handling.

Potentials and Requirements of an Integrated Solution for a Connected Car
Abstract
Within our society, individuality, comfort and mobility play an important role for working, travelling and living environments. Especially with the connectivity of a car to its environment, e.g. sensors, the communication to another car, to infrastructure communication and provisioning of relevant information to driver, can be considered as valuable technology of the future. An integrated solution for a connected car can be used for a safe, intelligent and comfortable mobility. Although there are significant results from research projects concerning car-to-x, e.g. simTD, and other infotainment and entertainment projects available, an integrated concept that covers general technical requirements, the drivers’ needs and business aspects is hard to find on the market. Significant requirements derived from technical and market insights are evaluated. These findings reflect the introduction of an integrated architecture that covers car-to-x communication, info- and entertainment and IT-security aspects.

ICT-Systems for Electric Vehicles Within Simulated and Community Based Environments
Abstract
The current living standard of industrial nations causes increasing CO2 emissions, particulate matter, and noise pollution. An essential amount of these environmental issues is induced by stop-and-go traffic within cities which is seriously characterized by short-distance freight transport trips with inner-city and suburban distances. The project Smart City Logistik (SCL) strives for a practical and short-term solution to this problem by ICT-Systems for electric vehicles (EVs). But planning, monitoring and analyzing for urban area logistics can become complicated and challenging to use. Evaluating them within acceptance tests requires a lot of experiments as well as a lot of equipment. The following approach within the SCL project, funded by the German Federal Ministry for Economic Affairs and Energy (BMWi), tries to use the ICT-system as it is and connects that system through a dynamically and procedurally generated simulation environment, based on real terrain and community data.
