One Hertz stimulation of afferents for 15 min with constant interstimulus intervals (regular stimulation) can induce long-term depression (LTD) of synaptic strength in the neocortex. However, it is unknown whether natural patterns of low-frequency afferent spike activity induce LTD. Although neurons in the neocortex can fire at overall rates as low as 1 Hz, the intervals between spikes are irre...

The excitation system of the hydro unit is a static self-excitation that uses thyristor rectifiers in three-phase fully controllable bridge connection with digital two-channel regulation characterized by very fast response (eng. high initial ratio). powered an transformer connected to busbars aggregate transmission ratio 14.4/0.42 kV. aim this project show characteristics old ABB UNITROL 5000 a...

In this paper, we prove the Tiling implies Spectral part of Fuglede’s cojecture for the three interval case. Then we prove the converse Spectral implies Tiling in the case of three equal intervals and also in the case where the intervals have lengths 1/2, 1/4, 1/4. Next, we consider a set Ω ⊂ R, which is a union of n intervals. If Ω is a spectral set, we prove a structure theorem for the spectr...

Published work on stuck-at fault test generation nearly exclusively considers circuits composed of only binary logic gates. Industrial designs commonly contain three-state elements , such as: busses and drivers, transmission gates, and bidirectional I/O. This paper presents extensions to state-of-the-art ATPG algorithms in order to handle these elements. A 25-valued signal model is used for tes...

in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...

Ethnobotany is briefly defined as a"human-plant relationship". Mankind has used plants a food source since ancient times, resorted to healing and accumulated their experiences. About 12.000 plant species grow in Turkey. The World Health Organization (WHO) determined the number of herbal medicines approximately 1900 it been that 20,000 are grown Turkey, 600 which for therapeutic purposes. This i...

The technology which could make our lives prosper within the four walls also help to create own corner of nature nourish. In this paper, we propose a smart gardening system that utilizes concept Internet Things (IoT) [1]. major goal project is reduce water consumption when and maintain garden remotely. Important plant data, like temperature, relative humidity, soil moisture, are continuously st...
