theory of computation, randomized algorithms, straight-line programs, output-polynomial algorithms Inputless straight-line programs using addition, subtraction and multiplication are considered. An output-polynomial algorithm is given for computing the output of such a program. The program runs in time polynomial in the length of the program and the length of its output. As a consequence, even ...

Background & Aim: Energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. If one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. In addition to the net income of the farmers, this issue would play a sign...

Effective and congestion-aware routing is vital to the performance of network-on-chip. The efficient routing algorithm undoubtedly relies on the considered selection strategy. If the routing function returns a number of more than one permissible output ports, a selection function is exploited to choose the best output port to reduce packets latency. In this paper, we introduce a new selection s...

There is a strong interest in the Submillimeter community to increase the IF bandwidth of SIS receivers in order to facilitate extra-galactic astronomy. However, increasing the IF bandwidth generally also means increasing the IF operating frequency of the mixer, because it is very difficult to achieve a good IF impedance match to a low noise amplifier (LNA) for more than an octave bandwidth. Co...

Background and aims: The main cause of many problems in developing countries is related to the provision of safe drinking water. Since the health of drinking water is important in the busy centers such as hospitals, clinics and health centers, this study was done to investigate the role of water coolers connected to the municipal system in microbial quality of drinking water in...

We investigate the limit sets of a network of coupled Kuramoto oscillators with a coupling matrix determined by a Hebb rule. These limit sets are the output of the network if used for the recognition of a defective binary pattern out of several given patterns, with the output pattern encoded in the oscillators’ phases. We show that if all pairs of given patterns have maximum Hamming distance, t...
