Miten A*-algoritmia voidaan hyödyntää peleissä
2016
Tässä tutkielmassa tarkastellaan, miten A*-algoritmi ja siitä johdetut HPA*- ja KM-A*-algoritmit toimivat ja miten niitä voidaan hyödyntään pelikartoissa. A*-algoritmi on hyvin käytetty polunetsinnässä, mutta sen vaatimat resurssit tekevät siitä hitaan peleille. HPA*- ja KM-A* -algoritmit pyrkivät nopeuttamaan A*:n toimintaa tinkimällä reitin tarkkuudesta. Kummatkin nopeuttavat huomattavasti A*:n toimintaa, mutta tuovat myös ongelmia. In this study we look at A*-algorithm and its modifications HPA*- and KM-A*-algorithm and how they work on game maps. A*-algorithm is still very widely used in pathfinding but its resource heavy pathfinding makes it slow to use in games. HPA* and KM-A*-algorit…
Two new sesquiterpene derivatives from the Tunisian endemic Ferula tunetana Pom.
2010
A new sesquiterpene ester, tunetanin A (1), a new sesquiterpene coumarin, tunetacoumarin A (2), together with eight known compounds, i.e., coladin (3), coladonin (4), isosmarcandin (5), 13-hydroxyfeselol (6), umbelliprenin (7) propiophenone (8), beta-sitosterol (9), and stigmasterol (10), were isolated from the roots of Ferula tunetana. Their structures were elucidated on the basis of extensive spectroscopic methods, including 1D- and 2D-NMR experiments and MS analysis, as well as by comparison with published data. The cytotoxicity of compounds 1-7 towards two human colon cancer cell lines, HT-29 and HCT 116, was evaluated. Compounds 3, 4, and 6 showed weak cytotoxic activities.
Use of prescription benzodiazepines and related drugs in family caregivers: a nation-wide register-based study
2022
Abstract Background objective indicators of sleep and mental health problems in family caregivers have rarely been reported. Objective to study the use of prescription benzodiazepines and related drugs (BZDRD) in Finnish family caregivers and matched controls. Design prospective follow-up in 2012–17. Setting nationwide register-linkage study. Subjects all individuals who received family caregiver’s allowance in Finland in 2012 (N = 42,256; mean age 67 years; 71% women) and controls matched for age, sex and municipality of residence (N = 83,618). Methods information on purchases of prescription BZDRD, including the number of defined daily doses (DDDs), between 2012 and 2017 was obtained from…
Association between difficulty initiating sleep in older adults and the combination of leisure-time physical activity and consumption of milk and mil…
2014
Background: Research has shown that engaging in leisure-time physical activity (LTPA) and consuming dairy foods can lead to better sleep. Combining these two non-invasive prescriptions may be more effective for helping people fall asleep. This study investigates whether participating in LTPA in conjunction with consuming milk and milk products has a beneficial association with difficulty initiating sleep (DIS) among older adults. Methods: The present study looked at 421 community-dwelling older people aged 65 years and older living in Ibaraki prefecture, Japan (mean age 74.9 ± 5.5 years, male 43.7%). We measured LTPA and sleep latency with the Physical Activity Scale for the Elderly and the…
Effects of exercise and diet interventions on obesity-related sleep disorders in men: study protocol for a randomized controlled trial.
2013
Abstract Background Sleep is essential for normal and healthy living. Lack of good quality sleep affects physical, mental and emotional functions. Currently, the treatments of obesity-related sleep disorders focus more on suppressing sleep-related symptoms pharmaceutically and are often accompanied by side effects. Thus, there is urgent need for alternative ways to combat chronic sleep disorders. This study will investigate underlying mechanisms of the effects of exercise and diet intervention on obesity-related sleep disorders, the role of gut microbiota in relation to poor quality of sleep and day-time sleepiness, as well as the levels of hormones responsible for sleep-wake cycle regulati…
Sleep and alertness in shift work disorder: findings of a field study
2018
Purpose Although shift work disorder (SWD) affects a major part of the shift working population, little is known about its manifestation in real life. This observational field study aimed to provide a detailed picture of sleep and alertness among shift workers with a questionnaire-based SWD, by comparing them to shift workers without SWD during work shifts and free time. Methods SWD was determined by a questionnaire. Questionnaires and 3-week field monitoring, including sleep diaries, actigraphy, the Karolinska Sleepiness Scale (KSS), EEG-based sleep recordings, and Psychomotor Vigilance Tasks (PVT), were used to study 22 SWD cases and 9 non-SWD workers. Results The SWD group had a shorter …
Sleep and sleepiness in shift-working tram drivers
2020
Driver sleepiness contributes to traffic accidents. However, sleepiness in urban public transport remains an understudied subject. To fill this gap, we examined the sleepiness, sleep, and on-duty sleepiness countermeasures (SCMs) in 23 tram drivers working morning, day, and evening shifts for three weeks. Sleepiness was measured using Karolinska Sleepiness Scale (KSS). Nocturnal total sleep time (TST) was measured with wrist actigraphy. SCMs and naps were self-reported with a smartphone application. Caffeine and napping were considered effective SCMs. Severe sleepiness (KSS >= 7) was observed in 22% of shifts with no differences between shift types. Rest breaks were associated with slight r…
Identifying long-term patterns of work-related rumination: Associations with job demands and well-being outcomes
2017
Item does not contain fulltext The aim of this 2-year longitudinal study was to identify long-term patterns of work-related rumination in terms of affective rumination, problem-solving pondering, and lack of psychological detachment from work during off-job time. We also examined how the patterns differed in job demands and well-being outcomes. The data were collected via questionnaires in three waves among employees (N = 664). Through latent profile analysis (LPA), five stable long-term patterns of rumination were identified: (1) no rumination (n = 81), (2) moderate detachment from work (n = 228), (3) moderate rumination combined with low detachment (n = 216), (4) affective rumination (n =…
Corporate social irresponsibility: review and conceptual boundaries
2017
PurposeThe purpose of this paper is to carry out a review of the academic literature about corporate social irresponsibility (CSIR) highlighting aspects that help us to define socially irresponsible behaviour and its relationship with socially responsible behaviour.Design/methodology/approachThrough a Boolean search of studies related to terms of irresponsibility undertaken from 1956 to October 2016, the authors develop a review of the literature focussing on the main perspectives used for defining the term of CSIR.FindingsThe paper provides a framework of three main dimensions for understanding the differences in the literature that defines CSIR: who defines irresponsible behaviour, an imp…
Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti
2021
In this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chroma…
