Abstract: Nanostructured ZnO capacitive relative humidity sensor was successfully designed and fabricated. Tin coated interdigitated electrodes (IDEs) with sensing area of 46.948mm2 were designed and fabricated to give the sensor its structure.Linear alkylbenzene sulphonate-capped ZnO nanoparticles were used as the sensing material (dielectric material) for the fabrication of the nanostructured ZnO capacitive relative humidity sensor. The nanostructured ZnO RH sensor was fabricated by deposition of the nanostructured ZnO ink on the IDEs using spin coating technique. The relationship between the capacitance values measured by the nanostructured ZnO capacitive RH sensor and the RH measured by DHT11 was determined using some saturatedsalt solutions. The relationship between capacitance and RH variations was 66.85% linear. The RMSE of the sensor was 8.37. The sensitivity of the nanostructured ZnO capacitive RH sensor was 0.161pF/%RH. The sensor was calibrated to obtain 100% linearity using linear regression and a simple model equation. The sensor was successfully calibrated to read relative humidity values ranging from 0%RH to 100%RH.

Abstract: This research presents the effect of an optimally located SVC on transmission system parameters using constant power, constant current and constant impedance, in which active and reactive powers vary with voltage in an exponential form. The Nigerian 330 kV, nine-bus system was used as a case study and simulated on NEPLAN. Calculated values of participation factor and voltage-reactive power (V-Q) sensitivity at least eigenvalue identified Aiyede Transmission Station (TS) as the optimal location of the SVC. The simulation results obtained show that for a constant power static load with SVC, the weak buses improved from 0.64348 to 1.00 pu at Aiyede TS, Oshogbo TS improved from 0.741988 to 0.95536 pu, Ikeja West TS improved from 0.94264 to 0.96498 pu and Ajaokuta TS improved from 0.9493 to 0.9659 pu, while the real power loss reduced from 74.218 to 47.521 MW. For a constant current static load, Aiyede TS improved from 0.8406 to 1.00 pu, Oshogbo TS from 0.8833 to 0.9738 pu, while the real power loss reduced from 31.84 to 27.625 MW. For a constant impedance static load, the voltage profile improved and the real power reduced from 18.81 to 17.742 MW. Hence, the power loss was compensated with SVC position at Aiyede TS..

Abstract: A rectangular shape microstrip patch antenna with different layers of substrate are proposed in this paper to show how the performances are changed for Terahertz (THz) applications by using different layers. The silicon dioxide as single layer, roger RT/duroid 5880(tm) and silicon dioxide as double layers, roger RT/duroid 5880(tm), silicon dioxide and FR4_epoxy as triple layers are used whose dielectric constant are 2.2, 4.0 and 4.4 respectively. But all times the height is same. A comparative report is created among the layers. Among them, triple layer gets the better performances. The return loss, bandwidth, gain, directivity and Voltage Standing Wave Ratio (VSWR) of the triple layers are -24.34 dB, 1.82 THz, 5.88 dB, 6.309 dB and 1.05 dB respectively. This triple layer antenna is resonated at 12.98 THz which can be used for biomedical applications.

Abstract: For better understanding of the operational characteristics of a dual stator winding interior permanent magnet synchronous motor, the steady-state performance analysis is required. Therefore, this paper primarily set forth to address the steady-state model and performance analysis of a line-start permanent magnet synchronous motor with capacitance injection for the enhancement of power factor and torque. The proposed machine has two sets of three-phase stator windings with one directly connected to the mains supply and the other connected to a balanced set of capacitors for leading current injection. The steady-state equations are derived using d-q model and the impact of capacitance on the various operational parameters investigated. Also, an equivalent circuit is deduced from the steady-state equations. Current in both the main and auxiliary windings contributes positively to torque production in the absence of external control circuitry..

Abstract: Power quality(PQ) is important topic of concern in power sector now. Increasing use of technology in industrial as well as domestic loads has led to various PQproblems. Harmonics, Voltage swell and sag are some common PQproblems caused due to the extensive use of semiconductor devices in the loads. In present paper it is proposed that by use of Custom Power Devices(CPD's) these PQproblems can be reduced. The CPD considered in this paper is Dynamic Voltage Restorer(DVR). Proportional and Integral (PI) controller and Repetitive Controller are the controllers used to generate the pulses for the active filter used in the CPD's. DVR and controllers are designed using MATLAB/SIMULINK. Results obtained by controllers are presented and compared..

Abstract: Thoughts identification via EEG signals is an interesting problem because of its potential application. This paper proposes the design of electric wheelchair controlled by brainwaves to support people with mobility and physical impairments. Through brainwave communication, electric wheelchair system can recognize some patients' commands like move forward, back, left, right, stop. Besides, wheelchair system can also recognize some other patients' requirements as eat, drink, call for relatives. The experiment result shows that the system works with high reliability and could be used in practice.

Abstract: The reconciliation of the photovoltaic (PV) nearby planetary group to the current conveyance
networks has carried new difficulties to the organization organizers. One of the most fascinating difficulties is to
forestall the effects of the PV irregular character on the consistent state framework activity conditions. Thus, the
principle point of the current work is to examine the impacts of the PV power discontinuity on voltage execution,
ordinary generator every day conduct and programmed voltage controller activity. Reproductions are
effectuated on 33-transport IEEE spiral conveyance power framework. Furthermore, so as to give a dependable
report, a genuine PV power profile is adjusted in this examination. The considered organization is demonstrated
and reenacted when the PV entrance and afterward a near report is set up.......

Abstract: The authors of the article explore the digital rights management in judicial protection of intellectual
property rights through the lens of civil law principles. The principle of protection of civil rights and interests is
defined as one of the basic principles of civil law regulation. The specifics of this principle, which are caused by
the specificity of the objects of intellectual property rights, the peculiarities of obtaining legal protection, are
determined. The provisions of the theory and the current legislation are analyzed in terms of defining ways of
protecting intellectual property rights as one of the factors that determine the peculiarities of the
implementation of the principle of protection of civil rights and protected interests in the field of intellectual
property.

Abstract: Recorded structures are significant as far as both unique development methods and social legacy. In this
way, material properties, development strategies and dynamic practices of these structures must be recognized so
as to save them later on by reclamation contemplates. This examination is planned to fill in for instance for
comparative structures in the area whose dividers were developed utilizing filled block with lime mortar and built
utilizing both lumber and strengthened solid chunks. In this examination, the arrangement design, development
methods and the material use of the structure were explored in detail. The mechanical and dynamic properties, for
example, compressive pressure, versatile moduli, shear pressure, normal frequencies and mode states of the
structure were resolved in-situ by level jack, shear and vibration tests......
