Customer Satisfaction in Information Provision in Bus and Coach terminals

The actuality of this research lies in the significance of changing the mobility traditions toward public transport usage. It requires considering various aspects of the customer experience in public transport services. Transport terminals are an asset to an area as they may act as catalysts for more active use of public transport. However, poorly planned, and sited terminals may generate problems and passengers reduction.The research aims to gain insights into the effectiveness of information visualization in bus and coach terminals and contribute to enhancing the overall passenger experience during journeys. The author is reviewing existing literature on information visualization in transport terminals and studies, or best practices related to improving passenger experiences through effective information design.The author used both quantitative and qualitative methods as sources of data, such as user surveys, expert interviews, and observations for understanding how passengers interact with existing information displays. From analysis, the Riga International Coach terminal has a good information system but misses some visualization tools for information provision. Thus, recommendations were made on how to improve information provision to enhance customer satisfaction.

Green transport solutions in a medium-sized courier company

This paper produces an analysis of the Latvia-based courier delivery company DPD Latvija to determine its possibilities and evaluate sustainable solutions that it has implemented already. The obtained results are used to select suitable green transport solutions using multi-criteria decision making and cost-benefit analysis methods and to develop appropriate recommendations that help to improve the sustainable solutions already used in the company or to introduce new ones.The main green transport solutions covered by the research are the most impactful ones and include switching to electric vehicles, usage of alternative fuels such as CNG, biodiesel and hydrogen cell, and an innovative model of crowdshipping. There are several more solutions covered in the research that can be used to increase a company's contribution to decarbonization.The resulting framework or action plan, can help the company make best investments in implementing green transportation solutions to reduce greenhouse gas emissions and potentially attract new customers. The added value of the work is the opportunity for another Latvian medium-sized courier company to use the proposed framework as a basis for creating its own plan.

Securing the future of remote work: Novel cyber threat mitigation strategies

The business environment has been greatly changed by the COVID-19 pandemic, accelerating the shift to remote work and increasing organizations' susceptibility to cyber threats. Conventional security approaches that concentrate on perimeter defense have been ineffective in addressing the challenges of remote work environments. This thesis examines new risk mitigation strategies for addressing cyber threats, focusing on implementation and effectiveness of zero-trust security frameworks. This study uses a mix of qualitative and quantitative research methods, including whitepapers analysis and expert questionnaires, to identify significant cybersecurity threats linked to remote work. It assesses the effectiveness of zero-trust principles and explores cybersecurity professionals' perception and understanding. The results show that adopting a zero-trust framework greatly improves an organization's security posture by implementing stringent access controls and continuous monitoring, reducing risks like breaches, phishing attacks, and other cyber threats. Furthermore, the research emphasizes the difficulties of zero-trust architectures implementation, such as the required cultural shifts within organizations and technical requirements.

Unsupervised machine learning approach for hierarchical graph-based representation of natural language text collections.

Managing big data efficiently is important in various fields, much so when data consists of human-written documents. Recent advances in Natural Language Processing (NLP), particularly LLMs, allowed to solve many task in this domain, despite the high demand for labelled data, compute resources and specialized skills.To tackle these limitations, current study proposed a NLP pipeline to identify topic hierarchies in collections of scientific publications. The work focused on evaluation of available unsupervised machine learning methods and quality metrics in NLP, and development of visualization techniques to build a prototype of the pipeline.Proposed solution is based on the hARTM approach optimized for interpretability. It demonstrated the capacity to infer human-interpretable topic hierarchies from collections of scientific texts and construct meaningful hierarchy of topic-based document representations. The visualization approaches rely on MDS to present inter-document similarity and Sankey plots to show document cluster relatedness within topic hierarchy.Utility was demonstrated on two datasets, focusing on interpretability and meaning of the topic hierarchy and associated topic definitions. Potential application areas include personal education and scientific writing.

The automated business processes integration and their impact on SMEs in Latvia

This thesis investigates the integration of automated business processes within SMEs (small and medium-sized enterprises) in Latvia's fintech sector, focusing on identifying specific challenges and opportunities. It emphasizes the role of automation in enhancing operational efficiency and enabling SMEs to allocate more resources to strategic and innovative tasks. The research has developed a conceptual framework and provides practical recommendations to assist SMEs in effectively integrating automated processes. The first chapter reviews digital transformation (DT) and business process automation (BPA), including robotic process automation (RPA). The next chapters focus on the survey and interview analysis using the Analytic Hierarchy Process (AHP) and Domain Mapping Matrix (DMM) methods. The fourth chapter presents a business case for integrating BPA in SMEs with examples and discussions on implications. Chapter five introduces a framework for future BPA initiatives and offers practical recommendations for companies integrating BPA.Key findings indicate that while automation offers substantial efficiency and cost-reduction benefits, its practical implementation requires carefully crafted strategies tailored to SMEs' needs.
