Watermarking is a method for the verification of the authenticity of a digital object. In this work we investigate the watermarking of audio signals utilizing watermarked images. We present a multiple watermarking scheme for the watermarking of digital audio signals. The proposed technique exploits an image as a watermark which has been already watermarked with a self inverting permutation. The watermarked image, is then embedded in the LSB values of the digital audio signal. By conducting a series of evaluation experiments, including an attack vector consisting of cropping, noise, and re-sampling attacks, we investigate the robustness of the proposed multiple watermarking technique and prove its potentials against various factors affecting each type of attack.

Decarbonization of energy generation is required to address the urgent need to combat climate change and meet the Paris Agreement targets. Photovoltaic Systems (PVS) are a major contributor to this solution, and they are expected to grow significantly faster than any other renewable-energy technology in the coming years due to their appealing features. This paper discusses the development of a two-way communication protocol between two transceivers and a custom-designed communication board installed on each PV array. With this configuration, it is possible to transmit the measurements of each PV cell in the array to a data recording and monitoring service. Additionally, the application can customize the operation of the strings that make up the array, by broadcasting special commands to them. A prototype experimental setup was constructed in order to test the communication between the PV array communication board and the uplink/downlink transceivers. The experimental results verify the feasibility and effectiveness of the proposed communication protocol between the Electronics Interface System (EIS) and the Smart PV array since the communication protocol meets the specification for transmitting the information from 1000 smart PV cells within one minute, as well as the strict timing requirements by the protocol for transmitting the parameters to the PV strings.

Wireless Sensor Networks (WSN) are expected to revolutionize daily life by connecting everyday objects with sensing capabilities, offering numerous opportunities for a wide range of applications. To facilitate the integration and enable all these opportunities to be realized, it becomes a necessity for middleware architectures that: (a) perform well in non-well-defined infrastructures, (b) are able to deal with the large number of users and heterogeneous devices integrated into it (ultra scalable), and (c) enable autonomy of the system overall. This work introduces a bio-inspired middleware optimized for wireless sensor networks proposing a refinement, the regional network, in a work published earlier as a bio-inspired self-adaptive architecture for the Internet of Things, while providing a comparison of other similar middleware approaches and a discussion on the motivating health monitoring scenario.

As the world is still recovering from the detrimental effects of the COVID-19 pandemic, one key aspect of the pandemic era were the global efforts for containment, case tracking and several other factors. While the scientific and governmental initiatives were largely successful and effective, a notable surge was observed in contributions from individuals and programming communities that developed their own software for COVID-19 by using data retrieval and analysis along with visualization methodologies. To achieve their goals, they turned their attention to knowledge exchange portals and asked questions regarding technological queries. In this paper, we present a collective platform that retrieves such questions from a well-known Q&A portal and visualizes the contained information. This platform serves as a useful tool for assessing programming and technological interest in COVID-19 related software development efforts while also promoting the open science principles.

During the Covid-19 lockdowns, e-learning and e-assessment became immensely popular worldwide. Exam Wizard is a web-based online e-assessment platform which provides a variety of features including question pool creation, automatic grading, automatic resumption, reusability, simplicity, exam monitoring and scheduling, weighted questions, a count-down timer, and automatic generation of statistics. Exam Wizard supports three kinds of users: administrators, instructors and students. This paper describes some new features of Exam Wizard, as well as the responsibilities and the User Interfaces (UI) of each user role. In addition, this paper describes the instructor’s experience from the use of Exam Wizard in pilot tests and midterm exams of technical courses offered by a higher education institution. The instructor found the tool useful because it produces immediate results, saving time and effort; when the instructor’s time is limited or in the case of large classes, e-assessment is the only viable option. During the evaluation of Exam Wizard the students appreciated the fact that they received immediate feedback, and the instructor happily stated that as long as there are questions banks available, it is a matter of minutes to create a new exam.

Dynamic data (including environmental, traffic, and sensor generated data) were, recently, recognised as an important part of the Open Government Data (OGD) movement. These data are of vital importance in the development of data intelligence applications. For example, various business applications exploit traffic data to predict, e.g., traffic demand and an estimated time of arrival. However, this type of data is inherently vulnerable to data quality errors produced by, e.g., failures of sensors and network faults. The objective of this paper is to explore the quality of Dynamic Open Government Data for the development of data intelligence applications. Towards this end, we study a single case about the traffic data provided by the official Greek OGD portal. The portal involves the use of an Application Programming Interface (API), which is essential for the effective dissemination of dynamic data. Our research approach involves the exploration and the evaluation of the provided data with regards to missing values and anomalies. We anticipate that this paper will contribute to the identification of organisational and technical challenges that hamper the effective dissemination of dynamic OGD.

Thesis defense is the procedure where a graduation candidate defends his thesis in front of a committee. This procedure usually involves a committee with special composition, while several other rules have to be enforced too. The problem of scheduling many thesis defenses in a designated period of time is a problem known to the timetabling community and is hard to solve. In this work, we experiment on a benchmark dataset that was released along with a formal description of the Problem. We employ three mathematical models and combine them to create a three phase approach. We test this approach with both Integer and Constraint programming solvers and manage to achieve high quality results, while most of them are better than the formerly best known.

The use of free and open source software is increasing and there is currently a tendency towards more openness in the provision of open source software. However, libraries that are used in conjunction with the software may affect the final license selection of the open source software and special caution is needed by software developers. Existing tools provide the means to extract license information from software projects, but this information has not been utilized towards recommending licenses that do not cause license violations. In this paper, we present our work towards the recommendation of licenses that satisfy the license compatibility requirement taking into consideration the licenses of third party libraries used in the software project. We have employed a dataset of 160 open source software projects to compare license compatibility using license extraction techniques implemented in different tools, i.e. Nomos and Ninka, whereas we have integrated the license extraction process in the findOSSLicense open source license recommender system, in order to recommend licenses that do not cause violations. The evaluation results and a small scale user study demonstrate the added value of the approach for the software developers in being better informed about license compatibility.

Difficulties of people with Autism Spectrum Disorder (ASD) in recognizing and expressing emotions, responding appropriately to them as well as in Theory of Mind (ToM) skills are a core symptom of the disorder. An important gap in the literature concerns structured training in emotions for the development of ToM and subsequently social reciprocity. This paper presents ToMtool, a software tool that systematically supports special education practitioners in helping people with ASD to improve perception of emotional states of themselves and others as well as thoughts and intentions that derive from them and choose an appropriate social response. The application promotes playful learning, personalized to the particular needs of each child. ToMtool focuses on the 4 basic emotions (happiness, sadness, anger, fear) with the possibility of expansion to more complex ones (e.g., surprise, anxiety) and concerns children of developmental age of 4 years and older. The application was developed following a user-centered design approach, involving speech and language therapists, psychologists, and special educators in its development process. To this end, semi-structured interviews and formative usability evaluations of intermediate versions of the application were carried out. A preliminary evaluation study of the ToMtool final version found that it met the users’ expectations and also identified issues for further improvement.
