Combinatorics

Combinatorics is an area of mathematics primarily concerned with counting and studying properties of discrete objects such as graphs, set systems, partial orders, polyhedra, etc. Combinatorial problems naturally arise in many areas of mathematics, such as algebra, geometry, probability theory, and topology, and in theoretical computer science. Historically, such questions were often studied using ad hoc arguments. However, over the last few decades, the development of general and powerful methods have elevated combinatorics to a thriving branch of mathematics with many connections to other subjects. The workshop brought together the established leading experts and the brightest young talents from different parts of this very broad area in order to discuss the most exciting recent developments, current themes and trends, and the most promising new directions for future research.

Investigation of the energy efficiency of fishing vessels: Case study of the fishing fleet in the Adriatic Sea

The reduction of ship emissions is one of the most important and current research topics in maritime sciences. Different technical and operational measures as well as various business strategies are being investigated to reach future decarbonization goals. Fishing vessels generally do not belong to the categories of vessels covered by the regulations of the International Maritime Organization (IMO), but their effect on humans and the environment is very important since fishing operations are mainly performed in coastal waters. Besides, fishing is considered an energy-intensive activity that produces vast amounts of greenhouse gas (GHG) emissions. Most fishing vessels are equipped with aged, low-efficiency diesel engines resulting in relatively high CO2 indices. This paper investigates the environmental impact of purse seiners and trawlers in the Adriatic Sea, based on their technical and operational characteristics, and taking into account the attained benefit for society. The energy efficiency index is formulated as a tool to compare different fishing vessels from an environmental viewpoint. The technical properties of purse seiners and trawlers operating in the Adriatic Sea are analysed from the relevant databases, and, based on the recorded realistic operating profiles, their energy needs and resulting emissions are assessed. The results show that trawlers have higher emission indices than purse seiners, mainly due to rather high energy needs and lower amounts of landed fish. However, when the income is taken into account, the difference between the emission indices of trawlers and purse seiners is lower.

Conceptual analysis of livable cities in the context of Ted Talks

Today, livable urban spaces are very important in terms of the healthy conduct of both individual and social life. Shaped in line with human needs such as education, housing, economy, cultural and social life, the city and the livability of the city is one of the current discussion topics with its variable and dynamic structure in addition to the factors it contains. From this point of view, the concept of "livability" has been questioned in the context of urban planning. Considering the temporal resilience of cities, the semantic dimension - qualitative studies - and therefore concepts are very powerful tools. Concepts are the basis of interpretation or theorizing. The aim of the study is to develop a different perspective by revealing the measurability of more livable and happier cities and the criteria they contain through discussions and discourses on this subject. In this context, the TED platform, which is easily accessible by large masses today and popular in terms of social awareness, has been used. The content of 65 texts focusing on urban research in TED Talks between 2007 and 2023 has been analyzed and a conceptual analysis has been made through NVivo, a qualitative analysis program. The content analysis method has been used in the evaluation of the texts, and discussions and interpretations have been made based on frequency frequencies. In light of the data obtained, it has been seen that more livable cities have been associated with the codes "architectural design", "technology", "energy" and "climate" respectively. As a result; it can be said that the concept of urban livability cannot be independent of the climate crisis, ecology discussions, and energy efficiency discourses as a solution to this crisis, and architectural designs that follow the technological level of the age, and the parameters discussed in the face of changing needs and situations over time can also change.
