Under hösten leker en inhemsk population av Atlantisk lax (Salmo salar) i Klarälven, Sverige, för att därefter vandra nedströms tillbaka till sjön Vänern. Vid älvens andra kraftverk sett från Vänerns mynning, Dejefors kraftverk, finns det planer på att ersätta ett av kraftverken mot ett nytt och det finns därför ett behov av att ta reda på hur laxens nedströmsvandring påverkas av det kraftverket som finns där i dag. Då alla kraftverk i Klarälven saknar fiskpassagelösningar är det extra viktigt att följa upp laxarnas passageöverlevnad under vandringen. Avsikten med denna studie var därför att ta reda på hur laxen rörde sig runt kraftverket, hur väl de klarade av att passera kraftverket beroende av vilken passageväg de tog och vilka faktorer som påverkade passageframgången. Under september 2020 fångades 40 laxindivider in när de var på väg uppströms inför leken. De mättes och märktes med telemetrisändare för att sedan transporteras uppströms och släppas ut nedanför kraftverket i Munkfors, varifrån deras nedströmsvandring förbi Dejefors kraftverk följdes och analyserades med hjälp av akustisk telemetri. Resultatet visade att det inte fanns någon signifikant skillnad mellan kön för när laxarna påbörjade sin nedströmsvandring. Kraftverket visade sig dock fördröja laxarnas nedströmsvandring då det tog längre tid för dem att passera kraftverket än vad det tagit dem att simma ner dit i den fritt strömmande delen av älven. Av de 31 laxar som anlände till Deje så passerade 27 av dem kraftverket, varav 13 individer överlevde (48 %). Överlevnaden var högre för individer som passerade via spillutskoven (10 av 12) än turbinerna (3 av 15). Det fanns en signifikant skillnad i mortalitet vid kraftverkspassage beroende på laxens längd och passageväg; långa individer hade en högre mortalitet (73 %) än kortare (25 %) och passagevägen hade en signifikant effekt på mortaliteten. Resultatet visar tydligt på ett behov av åtgärder för att förbättra överlevnaden hos lax vid passage av Dejefors kraftverk. Lösningar för att få fisken att helt undvika turbinerna och istället välja en annan passageväg vore troligen den bästa och effektivaste lösningen för att öka laxens överlevnad under nedströmsvandringen. / During autumn, the endemic Atlantic salmon (Salmo salar) migrate upstream to spawn in the river Klarälven, Sweden, after which they migrate downstream back to Lake Vänern. There are plans to remove one of the power houses in Deje, and replace it with a new power house, and before that happens it is important to study the downstream passage conditions at the site. As all power plants in Klarälven lack fish passage solutions, it is important to follow up the salmon passage survival during the migration. The purpose of this study was therefore to study how downstream migrating salmon negotiate the power plant, the route-specific passage survival and what factors that could affect their passage success. In September 2020, 40 upstream migrating salmon individuals were caught, measured and tagged after which they were transported and released below the power plant in Munkfors. Their downstream migration past Dejefors power plant was studied and analyzed using acoustic telemetry. The results showed that there was no significant difference between sexes in regards of downstream migration timing. However, the power plant turned out to delay downstream migrating salmon as it took longer time for them to pass the power plant than it took them to swim down the free-flowing part of the river. Of the 31 salmon that arrived in Deje, 27 passed the power plant, of which 13 individuals survived (48%). The survival rate was higher for individuals passing via spillways (10 of 12) than turbines (3 of 15). There was a significant difference in mortality rate at power plant passage depending on the length and passage route of the salmon. Large individuals suffered a higher mortality (11 of 15) than short (3 of 12) and a larger proportion of the salmon died when passing through the turbines than through spill gates. Based on the results, there was a clear need for improved survival rates for salmon passing the Dejefors power plant. The design of the turbines could be changed for increased survival, but at the same time other solutions that will make it possible for fish to avoid the turbines and instead choose another passageway would probably be a better and more efficient solution to increase the survival of the salmon during their downstream migration.

The graduation thesis is focused on the automatic operating of heating of the production hall of První brněnská strojírnaVelká Bíteš, a.s. The thesis consists of an analysis of present state of the heating technology and solution of the general conception of the automatic operating of the heating. Integrated part of the conception is heat-up of the supply water and drain off of the condensation water from the air heating units. Outcome of this graduation thesis is a design of the algorithm for operating of the regulated system. Remote supervision and control of the regulated system shall be ensured by the visualization setting, which shall be implemented into the station of dispatching centre. The accuracy of the design of the part of regulated system shall be validated as a design of PID regulator with the use of “Matlab” program and it´s module “Simulink”. To set up parameters of the PID regulator, “Ziegler-Nichols” method shall be applied. The objective pay-off period of investments for regulation controlling system is figured out as a part of this thesis as well.

This thesis deals with path-controlled grammars, which are grammars that place restrictions on the paths in a derivation tree of a context-free grammar. The goal of this thesis is to create an algorithm for conversion between the path-controlled grammars and the state grammars, which is a di erent type of regulated grammars. Another goal is to study the generative power of path-controlled grammars based on the conversion algorithm. The conversion algorithm is implemented and tested on a number of path-controlled grammars. Also, its complexity is discussed. Finally, a parsing tool for path-controlled grammars is implemented. Complexity of this tool is analyzed as well.

This work deals with advanced models of context-free grammars and explores the possibilities of adaptation and usefulness for deterministic parsing of non-context-free sructures by deep parsing method. It introduces adapted model of context-free grammar named LL programmed grammar and adapted deep pushdown automaton that makes deterministic parsing of non-context-free structures possible.

This thesis defines and studies two new types of automata, cooperating distributed pushdown automata systems (CDPDAS) and parallel communicating pushdown automata systems (PCPDAS).  CDPDAS and PCPDAS adapt the main concept of cooperating distributed grammar systems (CDGS) and parallel communicating automata systems (PCPDAS), respectively.  CDPDAS are proven to have the same power as PDA and this thesis further explores the reason why CDPDAS do not increase power while CDGS do and introduces an automata system inspired by CDPDAS that does increase the power.  PCGS have similar power as CDGS, but PCPDAS are equvalent with TM, which is proven by creating a communication protocol to access a second stack.

There is a concern that the ecosystems around the world are suffering from fragmentation. Ecosystems such as rivers have lost their connectivity to a large extent due to hydroelectric dams with no or insufficient passways for the natural flow of organisms, matter and energy. The Atlantic salmon, Salmo salar, is anadromous, migrating up rivers to spawn as adults and downstream to the sea as juveniles to feed. Before entering the sea, juveniles go through a parr-smolt transformation which alters their behavior, morphology, and physiology. Using radio telemetry, we assessed how the degree of smoltification, in combination with migrational timing and the juvenile’s size, affected their migration. Overall migratory success was found to differ significantly across the range of smoltification, with more fully smoltified juveniles having the highest probability (94%) of reaching the sea. No relationship was found between smoltification status and average migrational speed or delays when passing a dam. Migrational timing was also correlated to migrational success, with earlier juveniles being 50 % more likely to reach the sea than those leaving 2-3 weeks later. All of the tagged juveniles (28) that passed the dam were delayed by an average of 1,32 km/h relative to their median speed in the river, and 18 of the juveniles made it down to the sea. No effect of migrational timing was found with average migrational speed or with dam delays however. Unexpectedly, larger lengths were correlated with slower average migration speeds and greater delays when encountering a dam. This new knowledge about the degree of smoltification and its relation to migration success can help river management to direct their efforts in the right direction to strengthen salmon populations. / Ekosystem som älvar och åar har i stor utsträckning förlorat konnektiviteten till följd av vattenkraftverk med otillräckliga passager för det naturliga flödet av organismer, materia och energi. Atlantlax Salmo salar är en anadrom fisk vars livscykel kräver att den vandrar mellan olika habitat. Den vandrar upp i vattendrag som vuxna för att leka och ut till havet som unga för att äta. De unga laxarna går igenom en utvecklingsprocess (smoltifiering) innan de simmar ut i havet vilket förändrar deras beteende, morfologi och fysiologi. Med hjälp av radiotelemetri bedömde vi hur graden av smoltifiering i kombination med timing och storlek påverkade deras nedströmsvandring. Vi såg en avsevärd skillnad inom dem olika smoltifierings graderna och en lyckad nedströmsvandring, de fullständigt smoltifierade fiskarna var mest sannolika att klara nedströmsvandringen (94%). Inget samband hittades mellan smoltifieringsgrad och genomsnittliga vandringshastigheten genom ån eller förbi ett vattenkraftverk. En lyckad nedströmsvandring var relaterad till tid och vi fann att de som vandrade tidigt hade 50% större chans att nå ut till havet än de som lämnade 2–3 veckor senare. Alla radiomärkta fiskar (28) som passerade vattenkraftverket vart försenade med -1,32 km/h jämfört med deras genomsnittliga hastighet, av 48 märkta fiskar klarade sig 18 ut till havet. Oväntat nog var längre längd relaterat till större förseningar både i medianhastighet och vid passage av en damm. Den här kunskapen om sambandet mellan smoltifieringsgrad och lyckad nedströmsvandring kan förbättra insatser som görs i åar och älvar för att optimera för djur och natur.

The main research question was What are the relationships between parenting style, self-regulated learning (SRL) and the academic achievement of selected (upper) primary school students in Ethiopia? The following specific research questions were formulated: • What are the views of the students on the parenting styles, and on parental acceptance and control, the cognitive strategies they use, and their self-regulated learning? • What is the relationship between parenting style and SRL? • What is the relationship between parenting style and academic achievement? • What is the relationship between SRL and academic achievement? • Does SRL moderate the relationship between parenting style and academic achievement? In this study a correlational design was used, but it was also exploratory and descriptive. Data were collected by means of a self-report questionnaire, while the academic achievements of the students were derived from official records. The questionnaire was completed by 477 randomly selected students from two classes in each of five schools in Hawasa, Ethiopia. The analysis of the data was done by means of descriptive, correlation, and ANOVA tests. The major findings included the following: Most of the children experienced acceptance by their parents, in particular from their female parents/guardians. The best levels of acceptance were, for example, “When I get a poor grade at school, my parents encourage me to try harder”, or “I can count on my parents to help me if I have some kind of a problem”, and “My parents keep pushing me to do my best in whatever I do”. However, it was found that the parents seldom spent time merely talking to their children. The female parents/guardians seemed to control their children more than the male parents/guardians, and were more involved with their children. The children, though, also believed that their parents/guardians did not really know how they spent their leisure time. More often the children perceived their parents as being neglectful. Regarding their cognitive strategies, the students particularly made use of memorization. The cognitive strategies of the children whose parents were authoritative were significantly better than those of the other children. When a student’s self-regulation increased, his/her cognitive strategies also increased, and when the cognitive strategies improved, so did the average achievement. The parents’ parenting styles were also significantly related to their children’s achievement, and were moderated by cognitive strategies as co-variants. / Psychology of Education / D. Ed.

<p>he use of student-centered instructional strategies is a common practice in engineering classes. However, understanding which instructional strategies have a more profound effect on students’ performance and motivation is fundamental in course design. Such comparisons would allow instructors to design and plan their courses with better learning activities, which could lead to better student engagement and learning. In this three-paper dissertation, I explored the relative effectiveness of two instructional strategies 1) reflective thinking, and 2) teamwork participation by primarily using quantitative methods. Self-regulated learning theory and the Interactive-Constructive-Active-Passive (ICAP) framework guided the selection of these two strategies.</p><p>The first study investigated the relationship of an instructional strategy and a motivational construct through the following research questions: 1) Do students with high academic self-efficacy generate high-quality reflections? 2) To what degree do students’ self-efficacy beliefs and reflection quality scores predict their learning outcomes? Bivariate Pearson product-moment correlation and multiple linear regression were used to analyze the relationships.</p><p>In the second study, I focused on studying the relative effectiveness of two instructional strategies on a motivational construct in a larger engineering class. More specifically, the second study focused on understanding change in students’ participation in two instructional strategies (i.e., reflective thinking and teamwork) and students’ achievement goals. Further, the study investigated the unique contribution of instructional strategies on students’ academic performance and changes in achievement goals. I used stepwise hierarchical regression, simultaneous regression, and repeated measures ANOVA to analyze the data.</p><p></p><p>The third study focused on investigating the role of the same two instructional strategies on students’ academic performance and multiple motivational constructs (i.e., self-efficacy, task value, and engagement). I used structural equation modeling, and repeated measures ANOVA to analyze the data.</p>
