In time-sensitive and dynamic missions, autonomous vehicles must respond quickly to new information and objectives. In the case of dynamic task allocation, a team of agents are presented with a new, unknown task that must be allocated with their original allocations. This is exacerbated further in decentralized settings where agents are limited to utilizing local information during the allocation process. This thesis presents a fully decentralized, dynamic task allocation algorithm that extends the Consensus-Based Bundle Algorithm (CBBA) to allow for allocating new tasks. Whereas static CBBA requires a full resetting of previous allocations, CBBA with Partial Replanning (CBBA-PR) enables the agents to only partially reset their allocations to efficiently and quickly allocate a new task. By varying the number of existing tasks that are reset during replan, the team can trade-off convergence speed with amount of coordination. By specifically choosing the lowest bid tasks for resetting, CBBA-PR is shown to converge linearly with the number of tasks reset and the network diameter of the team. In addition, limited replanning methods are presented for scenarios without sufficient replanning time. These include a single reset bidding procedure for agents at capacity, a no-replanning heuristic that can identify scenarios that does not require replanning, and a subteam formation algorithm for reducing the network diameter. Finally, this thesis describes hardware and simulation experiments used to explore the effects of ad-hoc, decentralized communication on consensus algorithms and to validate the performance of CBBA-PR.

Pełny tekst źródłaSystems controlled by embedded computers become indispensable in our lives and can be found in avionics, automotive industry, home appliances, medicine, telecommunication industry, mecatronics, space industry, etc. Fast, accurate and flexible performance estimation tools giving feedback to the designer in every design phase are a vital part of a design process capable to produce high quality designs of such embedded systems.
In the past decade, the limitations of models considering fixed task execution times have been acknowledged for large application classes within soft real-time systems. A more realistic model considers the tasks having varying execution times with given probability distributions. No restriction has been imposed in this thesis on the particular type of these functions. Considering such a model, with specified task execution time probability distribution functions, an important performance indicator of the system is the expected deadline miss ratio of tasks or task graphs.
This thesis proposes two approaches for obtaining this indicator in an analytic way. The first is an exact one while the second approach provides an approximate solution trading accuracy for analysis speed. While the first approach can efficiently be applied to monoprocessor systems, it can handle only very small multi-processor applications because of complexity reasons. The second approach, however, can successfully handle realistic multiprocessor applications. Experiments show the efficiency of the proposed techniques.

Pełny tekst źródłaEffective time utilisation leads to greater freedom to use time as one would like to: to do more of the things one has always wanted to do; in short to enjoy life more. Like in any other business organisation, time for planning, organising, leading and controlling is managed carefully. The principal needs time to perform all the above mentioned tasks. In this study, the author accentuates that it is disconcerting that from time to time, there are schools that do not even have a time table when the schools open at the beginning of the year. It would be interesting to know how much time might be wasted as a result of a lack of planning, lack of priorities, paperwork and reading, meetings, unclear objectives, procrastination, lack of delegation, incompetent subordinates and many other time wasters. The purpose of the study was to determine the school principal’s understanding of the time management task and explore how effective school principals manage time in performing their different tasks. Fifty principals from Phumelela and Umbumbulu Circuits, under the Umlazi District completed a survey questionnaire and semi structured interviews were conducted. The researcher was able to determine the pattern of time usage. The findings revealed that factors hampering time management include among other things meetings that principals have to attend, departmental expectations, visitors, the organisational stress, administrative obligations and inability to differentiate between urgent and important matters to attend to hampers the principal’s time management tasks. The study among other things recommended that the provincial education departments need to provide appropriate training for school governing bodies that a well organised and goal directed system should operate to control school visitors in the schools’ interest.

Pełny tekst źródłaThe simultaneous performance of two tasks in a dual-task paradigm is often accompanied by dual-task costs (longer reaction times and/or higher error rates). These dual-task costs have been explained by the existence of a central bottleneck which prohibits the simultaneous processing of the two tasks at the central response-selection stage of information processing. The aim of the present work was to investigate several of the possible factors which determine the task processing order at this central bottleneck. The study shows that the arrival time of the two tasks at the bottleneck plays an important role in the determination of task order. Additionally, the influence of the arrival time on processing order is independent of the component task which is manipulated to test the influence of that task (i.e., visual & auditory task). A second factor that was manipulated is the instruction given to the participants. The results show that cognitive control processes are activated under certain instruction conditions. As a third factor, task requirements were investigated by comparing a temporal order judgement task with a dual task with random task order (i.e., temporal order judgement with the additional requirement to do a choice-RT task). The results suggest that the decision about the temporal order of the two tasks is located between the perception stage and the response-selection stage of processing.

Pełny tekst źródłaGlobalt ökad migration och rörlighet mellan länder har gjort det kritiskt för många att lära sig att tala ett andraspråk. Denna studie fokuserar på arbetande migranter som lär sig ett andraspråk vid sidan av sitt arbetsliv. Studien syftar till att stödja de studerande i sitt lärande av ett andraspråk utanför klassrummet. I synnerhet undersöker den hur användningen av en speciellt utformad applikation som syftar till att hjälpa eleverna att hålla reda på hur mycket tid de spenderar på att studera ett andraspråk påverkar deras engagemang och motivation för att fortsätta studera målspråket. För att hjälpa studerande migranter hålla reda på den tid som spenderas på språkinlärning (t ex att tala, skriva, läsa och lyssna) har en webbaserad applikation, TimeTracker App, som är tillgänglig via användarnas mobiltelefon, utvecklats av författaren och erbjudits till eleverna. Deltagarna i denna studie använde applikationen i cirka två veckor. En blandad metod användes: data samlades in genom halvstrukturerade intervjuer och genom att extrahera loggdata från applikationsdatabasen. Intervjudata analyserades med hjälp av en konventionell innehållsanalys och loggdata med hjälp av beskrivande statistik. Sammantaget visar studiens resultat att användningen av TimeTracker App gjorde det möjligt för respondenterna att bli mer medvetna om hur mycket tid de spenderade på sina studier och det inspirerade dem att ägna mer tid att studera målspråket jämfört med innan man använde applikationen. Resultaten tyder på att arbetande migranter blir mer motiverade och engagerade i sitt studerande av ett andraspråk när de använder applikationen.

Pełny tekst źródłaReal-time task scheduling problems are generally considered to be NP-hard problems. Therefore it is necessary to apply a heuristic search strategy on these problems. This project focuses on the development of a real-time scheduling algorithm using tabu search.
A dynamic real-time task scheduling problem is defined for a single processor. The tasks in the system are sporadic, mutually independent, non-preemptable with firm, arbitrary deadlines. This problem is represented with tabu search. For performance measurements a simulator has been designed and implemented. Simulations have been conducted comparing scheduler based on tabu search to two well known scheduling algorithms, namely: earliest deadline first and highest value first. It was expected that the scheduler based on tabu search would outperform highest-value first and it would miss fewer deadlines than earliest deadline, as soon as earliest deadline starts to miss deadlines. The results of the simulations conducted did not show this results. Nevertheless did the simulation results indicate that tabu search could be a suitable heuristic search strategy for real-time task scheduling problems. This project provides a starting point on which it is possible to continue work on enhancing the tabu search scheduler.

Pełny tekst źródłaThe relatively little amount of time that some college students spend reading their textbooks outside of lectures presents a significant threat to their academic success. One possible solution to this problem is the use of digital games as an alternative to outside-of-class textbook reading, but a review of previous research did not reveal much information on their efficacy when compared to traditional textbooks. Using Astin's theory of student engagement as a framework, the purpose of this quantitative causal-comparative study was to determine whether a significant difference in engagement, as indicated by mental effort and time on task, existed for college students who used a digital game-based textbook versus students who used a traditional print-based textbook. The 54 undergraduate college students in this convenience sample were randomly assigned to one of the two textbook types and completed an activity session at an individual workstation. Time on task was measured with a stopwatch and mental effort with the Mental Effort Scale. The results showed a statistically significant difference in engagement between participants in the digital game-based and traditional print-based textbook groups, Hotelling's T2(2, 52) = 25.11, p < .001, D 2=1.86. In the post hoc analyses, the digital game-based group had significantly higher time on task scores than the traditional print-based textbook group (t = 34.61, p < .001). The mental effort difference was not significant, although the mean mental effort score was higher for the digital game-based group. These results provide evidence of a digital game-based textbook's utility, and may inform college educators in their efforts to support a more diverse group of learners.
