BRAIN: Sentiment Analysis on Embedded Systems Blended Courses

The paper written by Răzvan Bogdan from the Department of Computers and Information Technology, Politehnica University of Timisoara, includes a presentation of a modality of integrating Embedded Systems Massive Open Online Courses (MOOCs) into blended courses. More than that, it also provides an evaluation of this approach: the sentiment analysis technique.

Starting with the explanation of MOOCs, the author insists on one type of courses which is still underrepresented in the field of blended courses – that of embedded systems. Consequently, we can understand that the aim of this paper is to understand, with the help of sentiment analysis, the way in which students react to blending embedded systems MOOCs into embedded system courses. We also find out that the blending variant is applied to Embedded Systems course at “Politehnica” University of Timisoara in Romania, third year of study.

    The Massive Open Online Course (MOOC) phenomenon has been growing in popularity and importance in the last decade, receiving valuable recognition from renowned universities from all over the world. MOOC can be simply defined as an online course aimed at unlimited participation and open access via the web. In the latest issue of the BRAIN Journal, Răzvan Bogdan’s paper approaches a modality of integrating MOOCs into embedded systems higher education. The academic field of Embedded Systems aims to enhance student’s understanding through various methods, however students find the concepts as being very monotonous and tend to avoid building practical solutions.…

BRAIN: Solving Optimization Problem via Vortex Optimization Algorithm and Cognitive Development Optimization Algorithm

The article written by Ahmet Demir from Harahalli Vocational School, Usak University, Ușak, Turkey and Utku Kose from Computer Sciences Application and Research Center, Usak University, Ușak, Turkey is a research which takes into account the importance of optimization and of solving its problems. They propose intelligent optimization techniques based on Artificial Intelligence in order to use them for optimization problems. So that they can provide a comparative study on the employment of classical optimization solutions and Artificial Intelligence solutions, two optimization algorithms are proposed: Vortex Optimization Algorithm (VOA) and Cognitive Development Optimization Algorithm (CoDOA).

Flow chart of the VOA

Optimization is defined as choosing the best set of alternatives for a certain thing, but also taking some rules into consideration. It is not important just in science, but in real life, too. A lot of fields in our life function now according to different applications which use optimization. But things do not stop here. Optimization also brings certain problems with it, as it is constantly changing. Consequently, different advanced optimization solutions have been introduced in time.

    Technology has become more than a phenomenon used for innovation, it is now a science put in the service of making human life easier. If in the past, taking a picture of yourself required a voluminous camera with an obscure chamber, nowadays we have our cameras to ourselves for they are incorporated in our gadgets. Therefore, we take pictures of everything we see – recording reality is just one swipe away and ready in the blink of an eye. However, sometimes is difficult to skim through thousands of photos in order to find a specific one. Nabil M. Hewahi and…

BRAIN: The Role of the Conceptual Invariants Regarding the Prevention of the Software Artefacts’ Obsolescence

Răzvan Bocu and Dorin Bocu from the Department of Mathematics and Computer Science, Transilvania University of Brașov, Romania, wrote a paper on the role of the conceptual invariats concerning the prevention of the artefacts’ obscolescence, emphasizing the software engineering. The aim is to understand the invariants’ role considering the continuous qualitative progress of the human artefacts, making a connection with software systems engineering. Approaching the artefacts’ obscolence is possible only through changes. They generate discomfort for other artefacts and the amplification of this discomfort beyond a certain tolerance may be called obsolescence.

Structure and behaviour during the specification of an artefact
Structure and behaviour during the specification of an artefact

There are works which underline the importance of the concept of structure during the modeling process of the systemic artefacts and the importance of the interface considering the capability of an artefact to cooperate. The structure (S) and the interface (I) are invariants and they are featured by certain stability (ST). By using these terms, the researchers want to explain which role the stability of these invariants plays regarding the obsolescence of the software systems.

BRAIN: Auto-generative Learning Objects in Online Assessment of Data Structures Disciplines

Nowadays, the IT industry is in a human resources crisis. The students tend to use their laptops and phones more often than in the last decades. The tutors are more and more loaded with teaching, research and administrative tasks. Consequently, the universities should take into account the use of technologies like LMSs (Learning Managements Systems), MOOCs (Massive Open Online Courses), GLOs (Generative Learning Objects) or AGLOs (Auto-Generative Learning Objects). This paper, written by Ciprian-Bogdan Chirila from Politehnica University of Timisoara, focuses on computer science disciplines (data structures and algorithms) and shows the way in which a tutor can build several auto-generative learning objects in order to assess the knowledge of a class of students.

The AGLO online assessment approach

Section 2 of the paper presents related works in the area of learning objects. We can find works which present a generative model for teaching computer science disciplines using Lego robots, principles for designing e-learning tools dedicated to the local automotive andustry, a similar model to the AGLO approach controlled by parameters but enhanced with dynamic learning and evaluation functionalities and so on. We discover that there are a lot of original model which can be used in the area of learning objects.

    Nowadays, learning is not anymore a passive process. It has become more dynamic and it has begun to use another medium than the written word or the exercise book. In the article titled Evaluation of Readiness for Distance Education of Students in European Universities, professors Diana Vasilevska, Baiba Rivza and Răzvan Bogdan present the results of an evaluation process concerning one of the most spread and new educational movements – distant education. The evaluation included students from different states of Europe as Poland, Serbia, Lithuania, Latvia, Belarus and Romania. The aim of this demarche was to see if all the…
