The British Library, London, holds a unique manuscript copy of  a Sanskrit text entitled Sarvasiddhāntatattvacūḍāmaṇi (MS London BL Or. 5259).  This manuscript, consisting of 304 large-size folios, is lavishly illustrated and richly illuminated. The author, Durgāśaṅkara Pāṭhaka of Benares, attempted in this work to discuss all the systems of astronomy – Hindu, Islamic and European – around the nucleus of  the horoscope of an individual personage.  Strangely, without reading the manuscript, the authors Sudhākara Dvivedī in 1892, C. Bendall in 1902 and J. P. Losty in 1982, declared that the horoscope presented in this work was that of Nau Nihal Singh, the grandson of Maharaja Ranjit Singh of Lahore, and this has been the prevailing notion since then.             The present paper refutes this notion and shows – on the basis of the relevant passages from the manuscript – that the real native of the horoscope is Lehna Singh Majithia, a leading general of  Maharaja Ranjit Singh.

In this paper, we propose a reflective augmented reality (AR) display system based on integral imaging (II) using a mirror-based pinhole array (MBPA). The MBPA, obtained by punching pinholes on a mirror, functions as a three-dimensional (3D) imaging device, as well as an image combiner. The pinhole array of MBPA can realize a pinhole array-based II display, while the mirror of MBPA can image the real objects, so as to combine the images of the real objects with the reconstructed 3D images. The structure of the proposed reflective AR display is very simple, and only a projection system or a two-dimensional display screen is needed to combine with the MBPA. In our experiment, a 25cm × 14cm sized AR display was built up, a combination of a 3D virtual image and a real 3D object was presented by the proposed AR 3D display. The proposed device could realize an AR display of large size due to its compact form factor and low weight.

Heuristic Techniques

This work focuses on the study of a task planning problem in a home care business. The objective is to schedule the working days of the available nurses, in order to assist all the active clients. Due to the large size of the real cases that must be faced, it is not possible to obtain exact solutions of the problem in short periods of time. Therefore, we propose an algorithm, which is based on heuristic techniques, to provide approximated solutions to the incidents that arise daily in the company. The designed algorithm is validated by obtaining the automatic schedule to solve a battery of real-like examples.

A set of associated left pedal elements of a sauropod dinosaur from the Upper Jurassic Morrison Formation in Weston County, Wyoming, is described here. Several camarasaurids, a nearly complete small brachiosaur, and a small diplodocid have been found at this locality, but none match the exceptionally large size of the pedal elements. Next to the associated pedal elements, an isolated astragalus, phalanx and ungual were found, which match the large metatarsals in size. The elements cannot be ascribed to diplodocids due to the lack of a ventral process of metatarsal I. Moreover, the morphology of metatarsal V has a broad proximal end, with a long and narrow distal shaft, which differs fromCamarasaurus. The size of the material and a medially beveled distal articular surface of metatarsal IV imply an identification as a brachiosaurid. This is the largest pes ever reported from a sauropod dinosaur and represents the first confirmed pedal brachiosaur elements from the Late Jurassic of North America. Furthermore, this brachiosaur material (the pes and the small nearly complete specimen) is the northernmost occurrence of brachiosaurids in the Morrison Formation.

Major-General Thomas Hardwicke retired following a lengthy career in India during which he amassed a considerable collection of natural history specimens and drawings. At his death in 1835, the bulk of these were transferred to the British Museum, together with various drawings, manuscripts and correspondence – the “Hardwicke Bequest”. The purpose of this paper is to review some of the material in the Hardwicke Bequest, particularly that related to botany now held in the British Library. The illustrations include the 16-volume set of “Plants of India”, a volume of Indian fungi, and another of plants of Penang. Among the manuscripts, a copy of the contents list of William Jack's hortus siccus of Malay plants presented to the Marchioness of Hastings appears to be a significant find. A manuscript copy of William Hunter's “Plants of Prince of Wales Island”, the earliest, though unpublished until 1909, flora of Penang is also notable. Hardwicke was an indefatigable describer of the plants he encountered, sending many descriptions, as well as specimens, to William Roxburgh and other eminent botanists of his day. The Hardwicke Bequest includes a large number of manuscript descriptions, notably 247 from Hardwicke's extended stay in Mauritius in 1811.

Abstract Orbital is one of the primary physical parameters that determine materials’ properties. Currently, experimentally revealing the electron occupancies of orbitals under the control of external field remains a big challenge due to the stringent requirements for samples such as the atomically sharp surface or defect-free large-size single crystals. Here, we developed a method with the combination of quantitative convergent-beam electron diffraction and synchrotron powder X-ray diffraction, and demonstrated the visualization of the real-space orbital occupancy by choosing LiCoO2 as a prototype. Through multipole modelling of the accurately measured structure factors, we found the opposite changes of Co t2g and eg orbital occupancies under different electrochemical states which can be well-correlated with the CoO6 octahedra distortion. This robust method provides a feasible route to quantify the real-space orbital occupancy on small-sized particles, and opens up a new avenue for exploring the orbital origin of physical properties for functional materials.

Abstract Numerical simulation is an economical and effective method in the field of marine engineering. The dynamics of mooring cables has been analysed by a numerical simulation code that was created on a basis of a new element frame. This paper aims at verifying the accuracy of the numerical simulation code through comparisons with both the real experiments and a commercial simulation code. The real experiments are carried out with a catenary chain mooring in a water tank. The experimental results match the simulation results by the numerical simulation code well. Additionally, a virtual simulation of a large size chain mooring in ocean is carried out by both the numerical simulation code and a commercial simulation code. The simulation results by the numerical simulation code match those by the commercial simulation code well. Thus, the accuracy of the numerical simulation code for underwater chain mooring is verified by both the real experiments and commercial simulation code.

AbstractThe Λ0 and association constants of salts of some widely used drugs (pharmacological agents) in acetonitrile have been determined. The division of Λ0 into single ion values λ0+ and λ0− has been made using λ0Na⁺ and λ0Cl⁻ values from the literature. The λ0+ and λ0− values have been found to be considerable in acetonitrile. The results suggest that many of the drugs can be present both as dissociated ions as well as associated molecules which are capable of absorption, dissociation and conduction (of ionic forms) in the lipid layers at very low concentrations. The phenomenon of unsolvation has been utilized to calculate the real dimensions of the drug ions (cations or anions) which are difficult to calculate from bond distances due to their large size and coiled configuration in aqueous solutions.

Nimonic 115

During a recent investigation concerning the growth of γ' precipitates in nickel-base superalloys it was observed that the sign of the lattice mismatch between the coherent particles and the matrix (γ) was important in determining the ease with which matrix dislocations could be incorporated into the interface to relieve coherency strains. Thus alloys with a negative misfit (ie. the γ' lattice parameter was smaller than the matrix) could lose coherency easily and γ/γ' interfaces would exhibit regularly spaced networks of dislocations, as shown in figure 1 for the case of Nimonic 115 (misfit = -0.15%). In contrast, γ' particles in alloys with a positive misfit could grow to a large size and not show any such dislocation arrangements in the interface, thus indicating that coherency had not been lost. Figure 2 depicts a large γ' precipitate in Nimonic 80A (misfit = +0.32%) showing few interfacial dislocations.
