This chapter introduces a theoretical framework, Optimal Control Theory, which will enable a phonology-extrinsic-timing-based, three-component model to determine values of controlled variables, and to model the influence of multiple factors on these parameter values. Key features of Optimal Control Theory models are discussed, as well as evidence for types of movement costs (including the cost of time) used in the models, and predictions of the models for the coordination of multiple effectors and hierarchical control. Finally, the chapter reviews Optimal Control Theory models currently used to account for timing phenomena in speech.

STM transaction schedulers were introduced to improve system performance. However, designing online transaction scheduling algorithms is challenging because at the same time they should: (i) introduce minimal scheduling overhead, (ii) minimize the resulting makespan, and (iii) minimize contention in the resulting schedule. In our previous work we developed the online transaction scheduler architecture and the four scheduling algorithms, named RR, ETLB, AC, and AAC (listed in increasing order of their quality), for scheduling transactions on the Python STM. Both AC and AAC use Bernstein conditions to check for pairwise data races between transactions, at the cost of time complexity that is proportional to the product of the sizes of transaction’s read and write sets, which may be significant. In this paper we propose a method for estimating existence of pairwise transaction conflicts whose time complexity is Θ(1). We validate this method by analysing the resulting transaction schedules for the three benchmark workloads, named RDW, CFW, and WDW. The result of this analysis is positive and encouraging – AAC using the new method produces the same result as when using Bernstein conditions. The limitation of the new method is that it may have false reports, both false negatives and false positives.

Introduction Asynchronous teledermatology (TD) has undergone exponential growth in the past decade, allowing better diagnosis. Moreover, it saves both cost and time and reduces the number of visits involving travel and opportunity cost of time spent on visits to the hospital. The present study performed a cost-saving analysis of TD units and assessed whether they offered a cheaper alternative to conventional monitoring (CM) in hospitals from the perspective of public health-care systems (PHS) and patients. Methods This study was a retrospective assessment of 7030 patients. A cost-saving analysis comparing TD units to CM for patients at the Hospital de Poniente was performed over a period of one year. The TD network covered the Hospital de Poniente reference area (Spain) linked to 37 primary care (PC) centres that belonged to the Poniente Health District of Almeria. Results We observed a significant cost saving for TD units compared to participants in the conventional follow-up group. From the perspective of a PHS, there was a cost saving of 31.68% in the TD group (€18.59 TD vs. €27.20 CM) during the follow-up period. The number of CM visits to the hospital reduced by 38.14%. From the patients’ perspective, the costs were lower, and the cost saving was 73.53% (€5.45 TD vs. €20.58 CM). Discussion The cost-saving analysis showed that the TD units appeared to be significantly cheaper compared to CM.

This article describes the author's approach to the analysis of the frequency of the biological terms in the printed texts of school textbooks of the full course of the biology of Kazakhstan secondary schools, allowed to reduce the cost of time for the processing in ten times. The authors of the article analyze the advantages and disadvantages of applications for text analysis and voice processing and offer their algorithm of fast counting of keywords in traditional texts. This research was carried out within the framework of the grant funding project of the Department of Science and Education of the Republic of Kazakhstan on the theme Creation of Trilingual Dictionary of Biological Terms with a Linguacultural Component.
