Recently, smart grids have been considered as one of the vital elements in upgrading current power systems to a system with more reliability and efficiency. Distributed generation is necessary for most of these new networks. Indeed, in all cases that DGs are used in distribution systems, protection coordination failures may occur in multiple configurations of smart grids using DGs. In different...

Introduction:Byrsonima garcibarrigae is an endemic tree of Amazonas state, Brazil, with pharmacological and chemical knowledge poorly understood. Aim: To investigate the antidiabetic potential B. stem bark. Methods: The bark was sequentially extracted by maceration hexane (EHBG), ethyl acetate (EABG), methanol (EMBG). antioxidant capacity, α-glucosidase inhibitory potentials anti-glycation capa...

In this letter, we present the first attempt of active light-emitting diode (LED) indexes estimating for generalized LED index modulation optical orthogonal frequency-division multiplexing (GLIM-OFDM) in visible light communication (VLC) system by using deep learning (DL). Instead directly transmitted binary bit sequence with DL, LEDs at transmitter are estimated to maintain acceptable complexi...

water in West Africa is based on European standards which are inadequate. This study was carried out order to determine the threshold values of physico-chemical parameters for monitoring quality tropical forest rivers Africa. Thus, were measured 324 surface waters collected three typical Taï National Park (Côte d’Ivoire) from May 2016 April 2017. Subsequently, sampling stations categorised as n...

Mobile Internet is rapidly growing and an enormous quantity of resources are currently available. Thus, the common mechanisms used up to now to locate resources, such as browsing and searching, do not look anymore to be effective in helping users in mobility. Indeed, the user’s personal information space can be very large, with respect to the limited interaction capabilities of mobile devices. ...

The superconductivity at 39 K discovered in MgB2 among simple binary chemical composition attracted much interest in its fabrication techniques and practical applications [1]. MgB2 superconductor exhibits many impressive properties such as highest critical temperature amongst intermetallic superconductors which means low cooling costs, impressive grain boundary transparency to the flow of curre...

We make the following progress on the dot–depth problem: (1) We introduce classes CB n and CL n of starfree languages defined via forbidden patterns in finite automata. It is shown for all n 0 that CB n (CL n) contains level n + 1=2 of the dot–depth hierarchy (Straubing–Thérien hierarchy, resp.). Since we prove that CB n and CL n have decidable membership problems, this yields a lower bound alg...

This study investigated the role of several chemokines and their receptors on malignant B lymphocytes recovered from 13 patients with chronic lymphocytic leukemia (CLL), 9 with hairy cell leukemia (HCL), 5 with mantle cell lymphoma (MCL), 5 with marginal zone B-cell lymphoma (MZL), 6 with small lymphocytic lymphoma (SLL), and 5 with follicular cell lymphoma (FCL). Flow cytometry analysis demons...

Hypergravity accelerators are a type of large machinery used for gravity training or medical research. A failure such equipment can be serious problem in terms safety costs. This paper proposes prediction model that proactively prevent failures may occur hypergravity accelerator. An experiment was conducted to evaluate the performance method proposed this paper. 4-channel accelerometer attached...
