We first show how a special case of Jackson’s 8φ7 summation immediately gives Warnaar’s q-analogue of the sum of the first n cubes, as well as q-analogues of the sums of the first n integers and first n squares. Similarly, by appropriately specializing Bailey’s terminating very-well-poised balanced 10φ9 transformation and applying the terminating very-well-poised 6φ5 summation, we find q-analog...
the experiment was carried out to study the impact of chilling and night break on the flowering of ornamental plants in their off-season period. larsenianthus careyanus (benth.) w.j. kress & mood is a wild potential ornamental ginger naturally growing in the evergreen forest of north eastern states of india was selected for the current study. the rhizomes were collected and stored at 15oc f...
The radiation emission of the heating coil of a Cone Calorimeter and the one of the halogen lamp of a Fire Propagation Apparatus have been studied experimentally for varying power settings. These are two standard apparatuses used for fire calorimetry. The objective is to characterize and compare the radiative flux spectrum received by a fuel sample during pyrolysis experiments. The deviation fr...
aTrademark of BSR (USA) Limited signals over the existing house wiring. The user pushes the desired key on a Command Console (Fig . 1) which is plugged into any ordinary domestic electrical outlet . The resulting coded signal is recognized by a selected module (Fig . 1) plugged into another ordinary outlet . (That other outlet may be in the next room, or it may be remotely located in the same h...
ABSTRACT Designing around patents is prevalent but not often appreciated as a means by which promote economic development through competition. We provide novel empirical study of the extent and timing designing patent claims. filing rate incandescent lamp-related during 1878–1898 find that enforcement Edison’s lamp in 1891–1894 stimulated surge patenting. studied specific design features lamps ...
This paper introduces the concept of risk applied to light flicker. It offers a novel stochastic assessment flicker produced by voltage fluctuations from devices in household. The has contributed with models patterns several household devices. severity been determined based on perception generalized LED lamp using an index defined as factor, what is contrast incandescent considered IEC 61000-4-...
