Voltage Profile Improvement for Soc Son's Low-Voltage Grid with High Penetration of PV Systems by Optimizing the Location of SVC Devices
2018
This paper presents a method that is applied to optimize the placement of Static VAR compensators in a real low-voltage grid in the Vietnamese territory. In this way, the voltage profile of the distribution grid turns to be improved. A heuristic method, the Binary Particle Swarm Optimization, is used to find a solution to this problem within the Matlab environment. A case study that considers a high penetration of rooftop PV systems in a branch of Soc Son distribution grid is implemented to show the efficiency of the optimization method for this specific application.
Indistinguishability-enhanced entanglement recovery by spatially localized operations and classical communication
2021
We extend a procedure exploiting spatial indistinguishability of identical particles to recover the spoiled entanglement between two qubits interacting with Markovian noisy environments. Here, the spatially localized operations and classical communication (sLOCC) operational framework is used to activate the entanglement restoration from the indistinguishable constituents. We consider the realistic scenario where noise acts for the whole duration of the process. Three standard types of noises are considered: a phase damping, a depolarizing, and an amplitude damping channel. Within this general scenario, we find the entanglement to be restored in an amount proportional to the degree of spati…

Strategic Asset Building and Competitive Strategies for SMEs which Compete with Industry Giants
2014
This chapter studies companies which are arguably business super-heroes – the small firms which despite the apparent handicap of very limited resources are able to compete against much larger, multinational firms – the micro-giants Davids that take on Goliaths. Through a process of detailed case studies of actual firms, analysis of asset structure, and experiments with a simulation model, the relationships between key assets, critical success factors, and micro-giant competiveness are explored. The model produces six scenarios reflecting different strategies for developing tangible and intangible assets and, critically, the balance between them. A level of aggression is needed in asset buil…
Elementary school principals’ work from the ecological systems perspective: Evidence from Finland
2022
The present study aimed to investigate elementary school principals’ work from the ecological systems perspective and which elements of their work are experienced as demands or resources. Semi-structured interviews were conducted with 22 principals. Qualitative content analysis was used to analyse the data. The results show that the way principals experience their work is individual and influenced by several internal and external factors. Some of the most extensive demands appear to be related to interaction with different stakeholders in situations where principals have the role of mediator in solving conflicting situations. Challenges also seem to arise in dealing with elements or issues…
Work-Related Social Media Use : The Mediating Role of Social Media Communication Self-Efficacy
2022
Social media use has become an indispensable part of knowledge work. Employees posting work-related content on social media are considered credible sources of information and have significant importance for how stakeholders, such as potential customers and future employees, perceive the organization. Therefore, employees’ ability to communicate about their work on social media has become a competitive advantage both for individual employees and for their organizations, especially in the professional service sector. Hence, understanding the role of employees’ ability to use these social media professionally is crucial for understanding the communicative behaviors of contemporary knowledge wo…
Risk of Contracting COVID-19, Personal Resources and Subjective Well-Being among Healthcare Workers: The Mediating Role of Stress and Meaning-Making
2021
The latest research suggests that the relationships between the risk of contracting COVID-19, personal resources and subjective well-being have rather an indirect character and can include the occurrence of mediating factors related to meaning-making processes and stress experiences. Protection motivation theory offers a theoretical paradigm that enables these associations to be thoroughly investigated and understood. The current study aimed to examine the mediating roles of meaning-making and stress in the relationship of risk of contracting COVID-19 and personal resources (self-efficacy and meaning in life) with subjective well-being among healthcare workers. A total of 225 healthcare wor…
Atšķirības insulta menedžmentā Somijā un Latvijā
2022
Insults ir pasaulē prominents nāves un invaliditātes cēlonis. Šī darba mērķis ir izpētīt insulta pārvaldības atšķirības starp divām ģeogrāfiski tuvām Eiropas valstīm – Somiju un Latviju. Neskatoties uz to, ka tās atrodas tuvu viena otrai un ievēro ļoti līdzīgas insulta pārvaldības vadlīnijas, pastāv atšķirības insulta iznākumā. Šis darbs apraksta insulta pārvaldības speciālistu viedokļus attiecīgajās valstīs, lai noteiktu atšķirības un līdzības insulta pārvaldībā starp Somiju un Latviju. Tika izmantotas kvalitatīvas izpētes metodes, lai iegūtu pilnīgu izpratni par insulta pārvaldības praksi attiecīgajās valstīs. Abās valstīs tika veiktas ekspertu intervijas, un tās tika izmantotas kā materi…
A Happy Marriage: Academia, Professional and Scientific Associations
2015
This paper advocates for a greater integration between Higher education and Professional and Scientific Associations (PSAs). With the development and adoption of Information and Communication Technologies (ICTs), the costs associated with the collection, storage, processing and transmission of information have been reduced. Eventually, the supply of information has boomed. However, more does not necessarily imply better. Free online resources can enhance the learning process, but the lack of quality controls is still a major concern. Additionally, learning demands some degree of organisation and structure. We argue that Higher education can potentially benefit from a closer relationship wit…
In Itinere STRATEGIC ENVIRONMENTAL ASSESSMENT of an integrated provincial waste system
2009
In the paper, the practical problem of analysing in an integrated way the performance of provincial waste systems is approached, in the framework of the Strategic Environmental Assessment (SEA). In particular, the in itinere phase of SEA is analysed herein. After separating out a proper group of ambits, to which the waste system is supposed to determine relevant impacts, pertinent sets of single indicators are proposed. Through the adoption of such indicators the time trend of the system is investigated, and the suitability of each indicator is critically revised. The structure of the evaluation scheme, which is essentially based on the use of ambit issues and analytical indicators, calls …
