We show that a continuous local semiflow of Ck-maps on a finitedimensional Ck-manifold M can be embedded into a local Ck-flow on M under some weak (necessary) assumptions. This result is applied to an open problem in [2]. We prove that finite-dimensional realizations for interest rate models are highly regular objects, namely given by submanifolds M of D(A∞), where A is the generator of a stron...

Pyroelectric harvesters use temperature fluctuations to generate electrical outputs. Solar radiation and waste heat are rich energy sources that can be harvested. Pyroelectric energy converters offer a novel and direct energy-conversion technology by transforming time-dependent temperatures directly into electricity. Moreover, the great challenge for pyroelectric energy harvesting lies in findi...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

In this paper a new parallel algorithm is presented for generation of all exactly m{block partitions of n{element set. The basic building blocks of the algorithm are an associative generator of combinations and a complex parallel counter. Consecutive objects are generated in lexicographic order, with O(1) time per object. The algorithm can be used for generation of all partitions within the giv...

Abslruct-In a coded frequency-hopped M-ary frequency shift-keying (FHlMFSK) communication system, it is known that if perfect side information about the jamming state is available to the decoder, substantial improvement in performance is possible. However, thermal noise, which is present in practical communication systems, can corrupt the jamming state information (JSI). In this paper, when JSI...

The main generator source of a longitudinal muscle contraction was identified as an M (mechanical-stimulus-sensitive) circuit composed of a presynaptic M-1 neuron and a postsynaptic M-2 neuron in the ventral nerve cord of the earthworm, Amynthas hawayanus, by simultaneous intracellular response recording and Lucifer Yellow-CH injection with two microelectrodes. Five-peaked responses were evoked...

The laser tracker has characteristics of high measurement accuracy and wide range. Laser technology, as an effectively large-scale measuring approach, plays a critical role in dynamic measurement. Currently, the static performance trackers been well studied. However, remain unclear terms evaluating its performance. circular trajectory generator system can quantify tracker. We developed standard...

In this research, a new technetium-99m generator has been developed with addition of Cerium oxide to alumina column.  The adsorption behaviors of 99Mo in the form of molybdate and 99mTc in the form of pertechnetate on CeO2/Al2O3 was investigated and showed that the adsorption capacity of molybdate on this generator is higher than usual generator using Al2O3. Ceric ions were selected as an addit...
