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.

Over the last decade, universities and other institutions of higher education (HEIs) worldwide have witnessed an evolution to their role relative to society – with increasing attention to external engagement and expectations on societal impact.

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

The prepositional ‘in’ and possessive pronouns, e.g., ‘my’ and ‘mine,’ in the context of attributions of mental states, such as “in my mind” or “in your mind,” threaten to confuse attempts to account for knowledge of other minds. This paper distinguishes proper from improper uses of such expressions. I will argue that proper use of the prepositional ‘in’ and possessive pronouns in the context of m

Within a single region, it is possible to identify opposite changes in flow production. This proved to be the case for several basins in southeastern South America. It remains challenging to the causes this behavior and whether changes in streamflow will continue at current levels or decline in the coming decades. In this study, we used the Soil Water Assessment Tool to simulate monthly river disc

Assessing the relative contribution of Land Use and Cover Changes (LUCC) and climate changes on runoff still represents a great challenge for water resources management. This issue is particularly critical for the Upper Paraná River Basin (UPRB), one of the most important basins in South America and responsible for most of the production of food, ethanol, and electricity generation in Brazil. In t

Ethnic recognition and collective titling have since the second half of the 20th century been promoted as ways of compensating for historical injustices and countering the destructive effects of capitalist development. While holding promise of autonomy, territorial rights, and resource control, they have also been seen as political technologies governing, spatially tying identities to place, and i
