‘Modern astronomy’ was introduced to Siam (present-day Thailand) when the Belgian Jesuit missionary-astronomer Father Antoine Thomas carried out astronomical observations in 1681 and 1682 in order to determine the latitude and longitude of Ayutthaya. Three years later a contingent of French Jesuit missionary astronomers observed a total lunar eclipse from Lop Buri, which marked the start of an int
The Burmese uḍhaya procedure represents a simplified calculation of the oblique ascension of the Sun that was used in Indian astronomy and astrology. The calculation has obvious connections with an Indian astronomical work, the Pauliśasiddhânta, and with works written by Brahmagupta. We investigate the Burrnese procedure mathematically to find out why it works.
Automatic tuning of PID controllers using relay feedback experiments has received attention on and off since it was first proposed and industrially implemented in a control system in the 1980s. While optimal experiment design and modern system identification easily outperform the original automatic tuner, they rely on computational resources that are not always available in industrial control syst
We study artificial halos generated by microscopic crystals suspended in an aqueous solution which is illuminated by a divergent light source. By measuring the diameters of the halos we can deduct the refracting angles of the crystals and compare them with known values.
The first great ruler to encourage the adoption of Western culture and technology throughout Siam was King Narai, who also had a passion for astronomy. He showed this by encouraging French and other Jesuit missionaries, some with astronomical interests and training, to settle in Siam from the early 1660s. One of these was Father Antoine Thomas, and he was the first European known to have carried o
People learn new languages with varying degrees of success but what are the neuroanatomical correlates of the difference in language-learning aptitude? In this study, we set out to investigate how differences in cortical morphology and white matter microstructure correlate with aptitudes for vocabulary learning, phonetic memory, and grammatical inferencing as measured by the first-language neutral
For decades, cluster initiatives and funding programmes have been used as instruments of industrial and innovation policy – addressing system failures by strengthening linkages among actors, fostering innovation and developing more effective innovation systems. More recently, a growing segment of these initiatives are also focused on driving system-level transformation and contributing to broader For decades, cluster initiatives and funding programmes have been used as instruments of industrial and innovation policy – addressing system failures by strengthening linkages among actors, fostering innovation and developing more effective innovation systems.

Novel problems often partially overlap with familiar ones. Some features match the qualities of previous situations stored in long-term memory and therefore trigger their retrieval. Using relevant, while inhibiting irrelevant, memories to solve novel problems is a hallmark of behavioral flexibility in humans and has recently been demonstrated in great apes. This capacity has been proposed to promo
AIMS/HYPOTHESIS: Prognostic factors and characteristics of children diagnosed with type 1 diabetes before 6 years of age were compared with those diagnosed at 6-13 years of age in the TEDDY study.METHODS: Genetically high-risk children (n = 8502) were followed from birth for a median of 9.9 years; 328 (3.9%) were diagnosed with type 1 diabetes. Cox proportional hazard model was used to assess the
There is a general acceptance that social capital and trust are critical for effective cluster development. While this behavioural additionality forms the central rationale for cluster policies, it remains poorly captured in evaluation. This paper explores progress in evidencing the ‘human element’ in cluster performance.The paper describes a long-term process of collaboration between academics, c
Induction heating of carbon fibre reinforced plastics, CFRP, has a great potential within different application areas, such as induction welding and curing of thermosets, due to fast and energy efficient heating. Simulation models can obviously be valuable for example during optimization. This article shows how temperature distribution during induction heating of CFRP based on woven fabric can be
This paper contributes to the geography of transitions literature by conceptualizing transition trajectories from a multi-scalar perspective. It combines an institutional perspective of transitions with conceptions of scale from human geography to derive a framework which explicates how (de-)institutionalization and re-scaling mechanisms condition different transition trajectories. Our conceptual
The focus on cancer rehabilitation has increased, but breast cancer patients still report unmet rehabilitation needs. Since many women today will live long beyond their diagnosis, there are multiple challenges for the healthcare system in supporting these women in their new life situation. A more individualized approach is seen as necessary to optimize the rehabilitation for survivors. Pathographi
The increased use of cloud and other large scale datacenter IT services and the associated power usage has put the spotlight on more energy-efficient datacenter management. In this paper, a simple model was developed to represent the heat rejection system and energy usage in a small DC setup. The model was then controlled by a reinforcement learning agent that handles both the load balancing of th
