Optimization and Reuse in Development of Large Software Systems
Abstract:
Software complexity is constantly growing, creating need for abstract points of view. Software modelling tackles this issue, offering various approaches to software abstraction at varying granularities and aspects. Despite the ever-changing nature of software, the software development phases remain constant, namely analysis, specification, design, implementation, testing, deployment and maintenance. The complexity of software also makes it more challenging to transform artifacts created within one phase, e.g. requirements, to artifacts of the next phase, e.g. component model. The research of both software modelling and automated software artifacts transformation always welcomes new ideas. We propose a novel software modelling method that provides both the structure and the behavior of the modelled system in one view, with the model being executable. To simplify the process of projecting software models into implementation, the software prototype supporting our modelling method also features automated transformation of platform-independent software models into platform-dependent source code. Additionally, we also research ways of transforming requirements specification to software design. Validity of software modelling methods and supporting prototypes is usually validated by performing user evaluation, which is a step yet to be taken.  More information ]]> [FMFI] Prednášky a semináre [FMFI] Kalendár Damas.Gruska@fmph.uniba.sk Wed, 06 Nov 2024 09:40:00 +0100 https://uniba.sk/ Friday 8.11.2024 at 13:15, Lecture room VIII (online too) Akihiro Yamamura (Akita University Japan):
Latin Regular Hexahedra (Joint work with Haruki Fukaura) Abstract:
Another generalization of a Latin square [1], called a Latin regular hexahedron, is introduced in [3]. A concrete construction using related combinatorial structures called a Latin three-axis design is given in the paper. It is shown that the construction does not produce all of the Latin regular hexahedra. We examine the construction for Latin regular hexahedra of small order. We call a Latin regular hexahedron defined using Latin three-axis designs separable and inseparable otherwise. We show that all Latin regular hexahedra of order 2 are separable using graph theoretical method, whereas there exists an inseparable Latin regular hexahedra of order 4. We are also interested in how many separable and inseparable Latin regular hexahedra of small order. Using graphs of Latin regular hexahedra and applying Cauchy-Frobenius lemma, we count the number of Latin regular hexahedra of order 2. Then we verify our counting is correct by computer experiment. The investigation concludes that every Latin regular hexahedron of order 2 is separable. The existence of a Latin three-axis design and a Latin four-axis design are equivalent to 1-factorizations [2] of the complete tripartite graph K2n,2n,2n and the complete quadripartite graph Kn,n,n,n, respectively. In addition, we discuss perfect 1-factorization of some of these graphs. In particular, we show that every 1-factorization of K2,2,2 is perfect.

Short cycle covers of cubic graphs with colouring defect 3, and more Abstrakc:
The shortest cycle cover conjecture (Alon & Tarsi; Jaeger; 1985) suggests that every bridgeless graph can have its edges covered with cycles of total length at most 7/5.m, where m is the number of edges. After almost 40 years, the 7/5-conjecture remains widely open. In this talk will discuss the current status of the conjecture and explain its links to other problems in the area. We also present results that imply the validity of the conjecture in two special cases. We show that the 7/5-conjecture holds (1) for cubic graphs that are three edges short of being coverable with three perfect matchings, and (2) for cubic graphs containing a pentagon with an edge whose removal together with endvertices leaves a 3-edge-colourable graph. This is a joint work with Jan Karabas, Edita Macajova, and Roman Nedela.

Today, 5 November, is Global Running Day which... What should we wear while running outside in autumn? There is a saying that there is no bad weather, only bad clothes. Even if it's cold outside, you shouldn't wear too many layers of clothing because after a while they get in the way. Put on two or three layers, which you can easily take off. It also depends on where you are planning to run, so adapt to the situation. Many people don’t run in the rain but if the rain is light it's much more pleasant to run in because the moist air makes breathing easier. Gentle rain can actually be helpful. If I'm not used to running, what should I do to prevent health issues from the get go? Some people get sick as soon as it gets cold. In the first place, consult any health issues with your doctor. If they advise you to run, start by walking. Some people who start running without any preparation might feel worse after two sessions than before. It’s safer to start by walking - count the number of steps per minute; beginners should take 60 steps per minute - every second a step. If you want to increase intensity, start by training for 10 minutes at a pace of one step per second. The body gets accustomed to the intensity. Of course, use your arms too. Next, increase intensity to 90 steps per minute, and once you can handle that, proceed to 120, and later 140, and more. Never rush it, do one intensity level for at least three training days. Once the intensity level feels easy, increase it. At the same time, monitor the distance you covered, extending it gradually. Beginners should not pay much attention to, or follow advanced runners who go faster. Those runners may have trained for six months or a year already. You can gradually work your way up to running 20 or 30 minutes at a time. What are the biggest beginner mistakes when running? People who once did some sport, then quit, and haven't done anything for ten years, often think they'll run the same distance at the same pace they did ten years ago. They remember that they used to run ten kilometres without any trouble. Your body might mobilise and do it, but various health issues may occur later. That is why the sequence of goals is very important and we should not overdo it right from the start. In the first and second weeks, the body should not physically feel the increased activity and your chosen intensity should be such that you do not end up out of breath and sweating profusely after your training session. Try to do the first fast walk and the first trot with a friend so you can speak with them. If you're out of breath to the point where you can't talk, slow down. Your body has to get used to the first intensity level. How should we warm up before running? I definitely recommend warming up the muscles lightly, e.g. by jogging for three to five minutes, to tell the muscles that our body is gearing up for physical activity. Later on, include static stretching – bend forward, bow sideways – and stretch the large muscle groups for the next few minutes. Move on to dynamic exercises next - circular movements of the arms, torso rotations, leg kicks, and then apply the running ABC to acquire proper running technique. Do not run on heels, because over time you might hurt your feet and your back. What is the proper running technique then? When running, you should land on the forefoot. Starting from the forefoot move your weight to the entire foot and follow through with the bounce into the next step; we call this double action at the ankle joint. Do not land on your entire foot nor hit the ground with your heel. These landings slow you down. Landing on the forefoot will spring-load your next step. What to do if we feel stabbing pain in the side or get a leg cramp? This ‘side-stitch’ is caused by an increasing concentration of lactic acid, created during exercise or heavy physical activity when there is a deficit of oxygen in the blood. When this happens, breathe deeply with your diaphragm, giving your body as much oxygen as possible. There are many styles of breathing while running - some recommend one step per inhale, one step per exhale, but I’ve seen recommendations to take two steps per inhale and one per exhale. It is important to find your own breathing rhythm and stick to it. With shallow breathing, little oxygen gets into the bloodstream and you are not in control of your body's reactions. In case of a cramp, massage the muscle and stretch it if you can. If you get a cramp in your calf, rest your foot on a step, bend forward and try to keep the muscle in a stretched position. If that doesn't help, massage the muscle vigorously to get as much blood into it as possible, which should help the cramp go away. I also recommend to help your body with supplements and vitamins. How to regenerate muscles after running? After your training, do some stretching to stimulate the muscles while not in motion - tension them, then relax, and then stretch. To avoid cramps, do some stretching exercises. What about muscle soreness after running? After each run, take a warm shower while massaging your limbs, moving towards your heart: in case of legs, going up. In this way, go through all muscle groups, including the back. If you can't reach it, try a towel or various other massage aids. This helps the muscles regenerate faster. After training, do simple stretching exercises, focusing on your limbs. Monitor your heart rate to find out the right intensity for you. There are various recommendations regarding optimal heart rate, some authors recommend to calculate the maximum heart rate by subtracting your age from 200 bpm to make sure you do not overload your body. However, with recreational running, the most important parameter is how you feel. How do you know that you’ve overloaded your body? When you wake up tired in the morning, you probably have an elevated heart rate. You should measure your resting heart rate before exercise (e.g. 60 bpm). Take the measurement before you get out of bed. Measure it again after exercise. Your know your body has not yet regenerated while your heart rate remains higher, e.g. 70 bpm. You don’t need to stop though, just switch to lighter forms of exercise, like bike or roller skates, to maintain muscle tone. Often, overweight people want to start running to lose the extra weight. However, for people with obesity, running is not a suitable form of exercise, because the extra weight might hurt their joints. They should start walking first, to adapt to the increased intensity of exercise. A general adjustment of diet is also very important. What shoes are suitable for running, and do you need special running shoes? Don't be tempted by fancy, attractive sneakers that don't have a good sole and don't hold your foot well. I do not recommend sneakers made of fabric which are more suitable for walking, or shoes with a higher heel. If you buy running sneakers, you should be clear about what you want to use them for. It is best to consult the people in a sports store.

Algorithmic approach to obtaining values of (k,g)-spectrum*
Abstract:
A (k,g)-graph is defined as a k-regular graph with a girth of g. A (k,g)-spectrum denotes the set of all possible orders of (k,g)-graphs. The smallest order in the (k,g)-spectrum corresponds to the (k,g)-cage, which is the smallest known (k,g)-graph. We will present various methods for identifying possible orders within the (k,g)-spectrum. As determining the smallest value of (k, g)-spectrum is a hard problem, we focus on cases where the minimal order (the order of the (k,g)-cage) is already established. Given the challenges of establishing the full (k,g)-spectrum, we provide both complete and partial computations for several pairs of (k,g).

Citizen safety is a priority At the simulated negotiations, the students were working with actual legislation that was being discussed or had already been approved. Teams consisted of students from different fields like political science, international relations, and law. Sofia was the prime minister (head of the government) of the Slovak Republic. She answered the questions of journalists and presented her statement. „My team included a national expert on the Cyber Security Act (CSA) and a national expert on the Artificial Intelligence Act (AIA), as well as the minister who had approved the Artificial Intelligence Act. Our team also included the ambassador who worked in the main preparatory body of the Council and combined the political position of Slovakia with the position of national experts. As a delegation, we worked together on our priorities and actions, presented national goals and negotiated with leaders of other member states at a summit. Slovakia did not have a clearly defined position, but since both laws were technical in nature, we were open to negotiations. We met with the Slovak representation at the EU, and with national experts who actually negotiated about these regulations. Experts and professionals from their respective fields gave students guidance regarding one of the acts. A student of the Slovak Medical University acted as the expert on cyber security,“ explains Sofia. Because her team included students from different fields, Sofia was able to obtain various solutions to the issue. As prime minister, Sofia tried defend small and medium enterprises on the internal market, making sure that none of the new European regulations drove them to bankruptcy, but stimulated innovation in sectors such as agriculture and medicine. Artificial intelligence can be used to innovate machines, for example. „It affects every single industry and every one of us, so it is important that we adopt this kind of regulation. The EU wants artificial intelligence to be used to our advantage. We know that students use it, so universities should also regulate it and make sure it is used correctly,“ thinks Sofia. At the summit, Slovakia presented plans for the regulation of artificial intelligence in order to make it a part of our everyday lives. Slovakia's priority was digital humanism, which would protect citizens from the risks of artificial intelligence - cyberattacks or camera surveillance. Cameras can be used to record individuals and use biometrics to recognize their faces. This can help catch perpetrators of crimes but also poses a risk of abuse of personal data. „One topic that was hotly debated was whether to authorise facial biometrics. Citizens should have a sense of security and know that their data would not be misused or their movements monitored. The act that we approved specifies that artificial intelligence tools like facial biometrics may only be used in exceptional cases - like a potential terrorist attack,“ says Sofia. The most important thing is to protect EU citizens The documents adopted will allow the European Commission to adapt the legislation to the developments in the area of artificial intelligence, which is advancing rapidly. The Cyber Security Act will create a single platform where data subjects can report its violations through the use of artificial intelligence, and the system would be supervised by the EU. „This should work like competition law - states can exchange general information and know-how. If, for example, one state detects a cyber threat, it informs other EU states so that they can prepare for the attack.“ During the negotiations, the students proposed an improved definition of artificial intelligence in the approved documents. They also called for a better definition of publicly accessible spaces monitored by cameras. „We wanted the Cyber Security Act to specifically state that its intention was to introduce of a friendly and innovative environment, but that the protection of citizens was also a priority. We also implemented tools which could supervise the testing of new start-ups or innovations. Furthermore, we made sure that the European Union would support research and innovation in the field of artificial intelligence and provide support to universities and research centres. Those will be permitted to use almost all forms of artificial intelligence in order to advance innovation and research,“ explains the future lawyer. Solutions in case of cyberattacks were developed During the negotiations, the students, who played the roles of prime ministers, had to deal with a simulated cyberattack in which hackers broke into the financial market. Stock prices began to fall rapidly and the value of the entire financial market fluctuated. Students from each country had to present a solution to this issue within two hours. „First, we discussed whether the situation would be treated as a cyberattack. We received a folder of information about our country, including our priorities, the countries with which we had the most intensive cooperation, the markets we were present on, and what our economy was like. At the summit, each country chose its own solution to the cyberattack. For example, Germany chose not to define the event as a cyberattack to prevent public panic. Slovakia, naturally, wanted to identify it as such, because otherwise we would not be able to fight future such attacks. Restrictions had to be very cautious so that market players would not panic and start selling their shares, which would escalate into an even greater instability of the market.“ Sofia finds her Brussels visit very useful. She met other inspiring international students and they learned from each other, she improved her English and was able to experience the operation of European institutions first-hand. „Each member state has the opportunity to express its opinion, adopt its position, there is no pressure on anyone, and everything is about compromises. We also visited the human resources department, where we received tips on how to write a good CV, a motivation letter, and how to prepare for a personal interview. I improved my presentation skills, because I needed to speak in English and in front of a lot of people,“ concludes Sofia.

You studied journalism at the Faculty of Arts of Comenius University. What made you choose this study programme? Both of my parents were journalists and when I was in elementary school, my father worked for the Pravda daily and my mom managed a magazine about Slovak expats. Ever since I was little we watched the news, discussed politics and world events, and I found all that very interesting. While studying at the Ladislav Novomeský grammar school in Bratislava, I wrote for the school magazine called “Tomášičkár” and even served as its editor-in-chief for a while. My and my classmates enjoyed working on the magazine and we particularly loved writing reports from school trips. After grammar school, I went to study at Comenius University. How did your university education affect your career? I have always been interested in many things and I easily get excited about anything, so journalism was the perfect fit. During my studies, I chose optional subjects that broadened my horizons, like comparative religious studies, cultural studies, sociology or psychology. Now, my editorial mandate permits me to call any expert and ask them how things work: from black holes to long-standing mathematical problems. The longer I do it, the more I think I could not have picked a better profession. You work as a reporter for the Denník N daily paper. What attracted you to news writing? During my studies I dabbled in television journalism when I worked as programming assistant for the Teleráno morning show. It was good experience, but I feel more at home in news writing. In addition to writing articles, I also record podcasts - it is no traditional radio production and the rules for podcasts are more relaxed; that is another thing I enjoy doing. You said you were interested in many subjects; was science something you focussed on from the beginning? Originally, my favourite subject was foreign journalism and that is what I went to study, but science got thrown in my way and I realised that it would be ideal for me. The topics are very diverse and as part of my work, I learn how concepts like evolution or the universe work, how an allergy to wasp venom develops, and similar things. I have the opportunity to dive into a topic, conduct research and then ask someone who actually understands it - I really like the process. My work also gives me creative freedom and I can choose topics myself, responding to any current events in science that come along. During the pandemic I wrote about covid, vaccine development or clinical trials, but when nothing major occurs, I’ll do something for fun, like a long interview about the life of ants. How did you enter the world of science? I was around when the science.sk portal was created and my job was to set it up, later acting as its editor-in-chief responsible for content. A while after that, when Denník N was founded, we began exchanging content and it published our articles. For several months, I worked in the PR department of the Slovak Academy of Sciences and then I went abroad. I spent three years in Australia, earning my living by manual labour, picking fruits and vegetables such as mangoes, pineapples and cabbage. It was physically demanding, but I have fond memories of that time. After returning to Slovakia, I was lucky because they still remembered me at Denník N and I was in the right place at the right time when they were looking to fill a post in the science department: everything worked out very elegantly. What does your daily job look like? I have been at Denník N for about four and a half years, and I collaborate on science topics with Otakar Horák. I choose topics myself, drawing from press releases and major international science portals. Usually, there is no shortage of topics, and I have a number of them going on at once: I record several interviews, which then haunt me at night, untranscribed. Alongside all this I communicate with the editor and other editorial staff, receive tips from them, but otherwise I have a lot of freedom in choosing my topics. My texts are mostly long-form, and I also produce a bi-weekly podcast about science named N2, and collaborate on an absurdist humour podcast called Toto vystrihneme (We’ll cut this out). Do you have a field or topic of science that fascinates you? This is a common question, but the answer changes with time. I really like space, nature, animal behaviour: ants, bees, anything really; and I'm interested in genetics. These are my favorite topics at the moment and are easily converted into stories. You published a book named ‘Ako chutí tarantula’ (What does a tarantula taste like), which contains a selection of 25 interviews with Slovak scientists.How were you choosing them? Me and my editor used the interviews produced for the N2 podcast series. Our first criterion was to choose information that does not obsolesce quickly, unlike the podcasts I did during the covid pandemic when the situation was developing rapidly. Next, we wanted to cover the broadest range of research topics, and avoid having ten interviews about space, but include a selection of texts about explosions in the sun, food testing, gem formation, etc. The book is not supposed to be a pre-meditated cross-section of Slovak science because the interviews themselves were recorded over several years depending on what was happening at the moment, what my interests were, or in response to a major discovery. In some interviews, researchers express their opinions about Slovak science and the reasons why they decided to stay in Slovakia, or leave the country. Recently, you succeeded among 33 applicants from 20 countries in a new European Research Council initiative. You were one of seven journalists, who won the Frontiers residency program to stay in a selected European research institution for five months. What was your project that earned you this success? I have long been toying with the idea of going somewhere and I was looking for a suitable challenge. One day I received an e-mail from the Slovak Centre of Scientific and Technical Information (CVTI) about this new programme, and once again I was in the right place at the right time. Zuzana Reptová from CVTI helped me with the numerous administrative details of the application. First of all, I needed to choose a European scientific institution doing frontier research. The stay is not about working in their PR department, but doing independent, original journalism and a project. I will be at the German Alfred Wegener Institute for Polar and Marine Research, which is the recipient of several ERC grants. It is located in a harbour near Bremen and has research stations in both the Arctic and the Antarctic, where experts study changes at the poles connected to climate change, a topic that I find fascinating. Polar climate change research is also important in view of various conspiracy theories concerning the climate crisis that are spreading and either downplay or even openly deny it. My goal is to interview scientists who have devoted their entire lives to this research and who have known for a long time what we often don't want to see. I want to relay their stories and experiences to the Slovak reader in a series of articles and potentially a book.
