Приведены результаты проведенных в лабораторных условиях исследований технологии сбраживания осадка сточных вод с рециклом биомассы и испытаний ее в промышленном масштабе. При проведении промышленных испытаний в варианте с рециклом биомассы удалось достичь увеличения распада беззольного вещества в среднем до 56,6 (значение в контрольном варианте 42,2). Увеличение распада беззольного вещества значительно улучшило водоотдающие свойства осадка. Среднее увеличение выхода биогаза составило 3. В процессе эксперимента негативного влияния технологии рецикла осадка на технологическую работу метантенка не зафиксировано. Полученные результаты исследований позволяют сделать вывод о высокой перспективности внедрения технологии сбраживания осадка с рециклом биомассы на московских очистных сооружениях. Расчеты показали, что при внедрении этой технологии можно ожидать сокращения объема сухого вещества на выходе из метантенков по сравнению с традиционной технологией на 9 10. Необходимость использования флокулянта при сгущении рецикла минимизируется улучшением водоотдающих свойств осадка и, таким образом, снижением его потребности при обезвоживании.

The results of laboratory studies and fullscale tests of the technology of wastewater sludge digestion with biomass recycling are presented. While conducting industrial tests of the technology with biomass recycling an increase in the disintegration of ashfree matter on average up to 56.6 (the value in the control option is 42.2) was achieved. The disintegration of ashfree matter significantly improved the dewaterability of sludge. The average increase in biogas yield was 3. During the experiments no negative impact of the sludge recycling technology on the operation of the digester was recorded. The obtained research results allow concluding that the introduction of sludge digestion technology with biomass recycling at the Moscow Wastewater Treatment Facilities is highly promising. Calculations showed that with the introduction of this technology a decrease in the dry matter amount at the outlet of the digesters compared with traditional technology by 9 10 can be expected. The demand for a flocculant for thickening the recycle is minimized by the improved dewaterability of sludge and, thus, the consumption of flocculant during dewatering is reduced.

A digital signature is a checksum which depends on the time period during which it was produced. Human palm biometric is one of the fastest, accurate, reliable and secure biometric techniques for identification and verification because it provides automatic authentication of an individual based on unique features in palm structure. In this paper, an efficient digital signature model for the document is proposed by using human palm. Human palm can give unique features which can be used in generating a secure digital signature. Therefore, this model consists of two sides: the embedding side and extracting side. The embedding side includes (1) image preprocessing stage:(color to grayscale and histogram equalization). (2) feature extraction stage:(GLCM (Haralick) algorithm). (3) Generating digital signature stage:(Elliptic Curve and Cubic Spline function with MD5 algorithm). While the extracting side contains extracting signature stage and matching stage. The accuracy of the generated digital signature by the proposed model is 100%, however false acceptance rate (FAR) is 0%, false reject rate (FRR) is 0%, and equal error rate (ERR) is 0%.

For PVA renewable source the output voltage is fluctuating as the solar irradiation is variable with respect to time. In conventional methods to control the DC voltage output of the PVA DC-DC booster converters are used. These converters don’t have high gain and also the ripple of the DC output voltage is high. The conventional PWM DC-DC booster converter is replaced with a feedback controlled dual switch converter for better control of output DC voltage with higher gain and reduced ripple. In this paper, the output of the dual switch converter is fed to controlled six switch inverter running a permanent magnet synchronous motor. The motor is controlled with a reference speed control technique for change in variable speed and torque operations. The input voltage of the converter is also made variable with respect to time with change in solar irradiation; the response of the proposed converter is good even for this condition. MATLab/Simulink is used to design all the modules of the proposed work.

Aggregates used in concrete are fast depleting natural resource and the quarrying of which is causing environmental issues. Hence, the use of aggregate from alternate sources such as from waste discarded glass, from foundry sand discarded after metal casting process and sea shells is investigated. Compressive strength of concrete with glass powder, foundry sand and sea shell is studied individually. Concrete is cast with glass powder and foundry sand as 5%, 10%, 15% and 20% replacement of fine aggregate and with sea shell as 5%, 10%, 15% and 20% replacement of coarse aggregate individually. It is observed that compressive strength of concrete decreases with glass powder, foundry sand, and sea shell. Fine aggregate replaced by 10% glass powder, 10%, foundry sand and coarse aggregate replaced by 10% sea shell have the least decrease in strength when compared to control concrete mix.

Published: November 2019

Machine learning has been used for solving the Robot Navigation Task through the wall-following control. The wall-following control involves the movement of the robot in some directed direction maintaining a constant distance from a given wall. The path of the movement of robot is measured by ultrasonic sensors. Many machine learning methods have been used for this problem, as classifiers, but Convolution Neural Networks (CNN) outperforms them all with almost 98% of accuracy. This study compared the performance of five classifiers SVC, MLR, ANN, CNN-1D, and CNN-2D, which play the part of controller in the navigation work. We have used the ultrasonic sensor data to understand the hidden pattern in the navigation work and classified the actions by robot in terms of different motions performed by robot in response to it. The classification reports of CNN-2D and CNN-1D with Artificial Neural Networks (ANN) have also been presented in this paper. The smart Data-Enhancement used in proposed method significantly improves the classification performance of all classifiers, especially CNN.

Contactless excitation of piezoelectric (PZT) component through focused E-field has been investigated in this work. In the intended technique, E-field is focused to ground electrode from a curvilinear-shaped potential electrode so that maximum E-field can penetrate sufficiently through PZT component which is positioned inbetween the electrodes. Simulation analysis shows that the contactless energization of PZT component is due to electric resonance as well as piezo-electric resonance. The maximum vibration occurs across the PZT components when the E-field generator operating frequency (f0) matches with the mechanical resonance frequency (fm). The max output power across the contactless energized PZT component mainly rely on operating frequency, resonance, position & resistive load. The output power achieved across the contactless excited PZT component by focused E-field generator is higher than the output power achieved across the contactless excited PZT component by capacitor like E- field generator. The max output power of 9.9mW is obtained across PZT component at 1295 kHz resonance frequency (fr) and 19.5 kΩ optimum loads with an input of 50 V and 8 mm electrode separation. By enactment of this excitation methods provide free actuation of PZT component so as to overcome the difficulties associated with the confined motion for different applications.

In this era of globalization every country is adopting the policy of import substitution and export Promotion. For the export promotion many countries such as USSR, Mexico, and Jordan etc. adopted the policy of Special Economic Zones (SEZ). It was believed that the SEZ are the instrument of export promotion, earners of foreign exchange, stimulator of employment and foreign investment. Special economic zones concept has evolved across the globe and several developing countries have adopted this policy for set-up of industrial zones that focus on exports and helps in generating economic opportunity and able to attract Foreign direct investment. So SEZs can be defined as a geographically delimited area which is physically secured, has single window clearance system, less complicated administrative unit and duty free environment. In this paper, an attempt is made to review the concept of Special Economic Zone and its impact on the exports from India. The study is based on secondary sources of data and it covers for the period of recent ten years.

Fish production in Pangasinan specifically fish farming is mainly monopolized by people with financial capabilities. Local farmers work for these people or rely mainly on working with these capitalists. NIFTDC BFAR Dagupan conceptualized vertical farming for small scale fish farmers. However, these fish condo consumes local grid power and Dr. Westly Rosario of NIFTDC BFAR Daugupan aimed to help these farmers even without local grid supply. A design of solar powered aquarium was developed to respond to this need. The design system uses solar panel as its source. Computations show that a 400-watt solar panel can supply the system load including the motor pump. Charging and discharging time of the battery were also determined. Maximum panel output was also suggested following the optimum tilt per month. An automatic water filtering system was also included that measures both dissolved oxygen and pH level of the water inside the culture chambers. Nominal values of pH and dissolved oxygen were set to automatically normalize these values according to the appropriate aquatic living conditions of African catfish. An ROI of 0.14 and payback period of 7.84 were determined. Computations were based from the capital investment of BFAR Dagupan. Growth and yield rate of African catfish are expected to improve in the application of the system to the vertical aquariums.

The need for studying the flow behavior of the treated juice in the three main parts of the process (After mixing, after Pasteurization and after cooling) is essential in predicting the pumping power requirement. In the present paper, the rheological properties of mango juice are determined at the end of three steps in the production line: First, after the mixing step, second after homogenization and finally after cooling. The following properties determined, Brix concentration, Acidity of solution, and the rheological properties. Mixed juice showed Bingham behavior with values of yield stress decreasing with increased temperature. The activation energy was determined to equal about 24 kJ.mol-1. Samples collected after the homogenization step exhibited shear thinning behavior with an almost constant flow index of 0.525. The activation energy was determined as 10.93 kJ.mol-1. The juice samples collected from that step exhibited a mild thixotropic behavior. The results of the third step involving cooling of the homogenized juice revealed that the liquid reverted to Bingham behavior with values of consistency index decreasing with increased temperatures. The calculated activation energy equals 11.22 kJ.mol-1.

The spectrum efficiency in wireless networks is becoming increasingly important to satisfy the expanding need for remote services, particularly reasonable remote Internet services. Various wireless users will encounter distinct circumstances on the channel, which are time-varying and location dependent at a given time. To exploit the wireless time-varying nature, a cross-layer design method called Opportunistic scheduling is used. Opportunistic scheduling increases the overall system performance and user fairness requirements under certain Quality of Service (QoS). The main idea behind this opportunistic scheduling algorithm is to make use of the time-varying channel and a user with the highest channel condition should be scheduled at a specified moment. The progressions in Wireless innovation made opportunistic scheduling a famous research point as of late. The demand for QoS provisioning is increasing and using a scheme which allows only users with best channel conditions to transmit at high transmission power cannot be satisfied. The objective of this paper is to implement opportunistic scheduling while adhering to fairness and QoS constraints, using Max-Min fair algorithm. In brief, a wireless network has been simulated using Qualnet simulator. An opportunistic scheduler that uses Max-Min fairness scheduling has been implemented, at the Media Access Control (MAC) layer. Here, the base station gathers the Signal to Noise Ratio (SNR) of all the nodes and then schedules the users using Max-Min algorithm, based on these SNR values. The same scenario is then implemented using Strict Priority, which is a Non-opportunistic scheduling algorithm. The resulting throughput, fairness, delay and jitter of both the algorithms are then compared.

An InGaP/InGaAs/GaAs dual channel High Electron Mobility transistor (HEMT) with three δ doped layers with different doping densities is modeled and simulated in this paper by using two dimensional ATLAS simulation package from Silvaco software. Different DC performances (Drain characteristic and Transfer characteristics) at various voltage levels are analyzed and results are compared by taking the gate length of 500nm and 800nm at two different temperature levels (250k and 300k) to determine the efficiency of the device for high speed digital device applications. The paper describes the effect of parasitic access resistance on device gate length and effect of mobility by varying temperature. High drain current drivability, large carrier densities and better saturation characteristics are realized because of the inclusion of InGaAs channel instead of GaAs DC structure and schottky behavior of InGaP layer. The studied double channel HEMT with proper dimensions and accurate doping profile makes it a promising device for high performance electronics device applications.

The research was aimed at analyzing the microbiome of the skin, the gill lamellae, and the intestines of sturgeon fish. After examining the structure of the microbial community of bastard sturgeon bred in the conditions of closed-circuit water supply, a conclusion can be made both about the physiological state of the fish and about possible pathologies. For making a collection, the following samples were taken from five bions in pool No. 3 and five bions in pool No. 6: the surface of the skin, namely, pieces of fins of sturgeon fish of Bastard Sturgeon species, and gill lamellae (by slicing the gills), and from the intestines (by introducing a swab through the cloaca). The samples were fixed in 96 % ethanol at the material collection locations. Each sample was assigned an identification number. DNA was isolated from the tissues of sturgeon using the set of reagent (MACHEREY-NAGEL NucleoSpin Soil) made by MACHEREY-NAGEL (Germany). The obtained sequences were processed using the Trimmomatic Fastq-Join toolkits, and OTU-picking was performed using the QIIME package. The studies showed that the greatest differences between the pools were in the microbiomes of the intestinal hole, and the least — in the microbiomes of the fin surface, i.e., the effect of a pool on the expression of the differences between the microbiomes increased in the following row: fins – gills – intestinal communities.

Energy storage system plays a crucial role in providing stabilization and improving power quality in isolated microgrid, especially in renewable energy based microgrid systems. Among the renewable sources, Photovoltaic (PV) based power systems are famous and increasing day by day due to its merits and advantages. Three phase fault are common in microgrid and leads to unsteady condition in the PV output power. When there is a fault in solar PV system, the photovoltaic power output decreases and results in a bnormal voltage drop in the system. Efficiency and reliability of PV system is also a major issue. To overcome the issues occur due to fault in isolated PV system, it is to have Fault Ride through (FRT) capabilities. When failure occurs in PV system, FRT c apability allows the system to maintain stability. FRT also allows the PV system to survive the system during the condition of fault on the system. Moreover, energy storage systems plays major role in the PV based systems. A Super Conducting Magnetic Energ y Storage system (SMES)is proposed in this paper which is for providing power stabilization in isolated microgrid under fault condition. SMES can provide the real and reactive power according to the requirements of PV based power system. The proposed SMES can be a good solution for minimizing the effect on the system due to fault condition in PV system. Using MATLAB/SIMULINK, isolated PV with SMES was simulated and analysed for its performance with and without fault condition. This proposed theory is proven by an extensive simulation results.

In wireless communication era, we need the antennas with low profile, light weight, planar but can meet the characteristics of non-planar structures, with ease of fabrication, flexibility in terms of electromagnetic parameters like radiation pattern, gain, impedance, polarization etc. Microstrip patch antennas, which come at low cost, size, good performance, ease of installation and easy integration to circuits, high efficiency, are suitable in that context. The Principle of slot is used on the patch which decreases the radius of the circular patch antenna, so as to reduce the size. In this work various Ircular microstrip patch antenna arrays are intended for the application of WLAN and Wi-Max at 2.4GHz for the improvement of gain. Single microstrip patch antenna and planar arrays of 1x2 and 2x2 ircular microstrip patch antennas are designed using strip line feeding technique and simulated on FR4 substrate. The planar antenna arrays are simulated using the High Frequency Structure Simulator (HFSS) software version v17.2 and the parameters like gain, return loss, Bandwidth and VSWR are evaluated at 2.4GHz frequency and the same are presented.

Since 1960 Using crumb rubber modifier (CRM) in hot asphalt mixtures has become a frequent practice in road construction. Using the CRM by the dry process method is not commonly used, although it has great advantages such as it is less fuel consuming and it does not require storage container like the wet process method. This research evaluates the mechanical properties of dense graded asphalt rubber mixtures manufactured using the dry process. The results obtained from this mixture compared with similar asphalt mixture without CRM. The mechanical properties of all mixtures evaluated using a set of tests such Marshall Stability and flow test, moisture susceptibility test, indirect tensile strength test, dynamic modulus and flow number test. The research results showed that using CRM with 0.75% of aggregate’s weight increased the mixture’s stability, flow and enhanced its cracking and permanent deformation resistance.

Economic dispatch is an important issue within the electrical system in meeting the lowest cost of the system and is subject to transmission and operating constraints.The power system operation and planning economic dispatch required a reliable technique to achieve minimal cost in economic dispatch otherwise the objective to minimize the generation cost fail. The electrical transmission network does not make complete electricity generation in Single-area economic dispatch. Thus, to complete the economic dispatch for the power transmission system, the multi-area network is proposed. The Multi-Area Economic Dispatch(MAED) connects two or more areas through a tie-line. Each region has a specific cost and load pattern. Tie-lines are used as connectors to enable power switching between regions. 31-Bus test system tested using an algorithm known as Differential Evolution Immunized Ant Colony Optimization (DEIANT) with different case studies with several trials taken to assess the consistency of results. Comparative studies with Pre-Optimization and Newton Rap son revealed that DEIANT technique is more reliable for multi-area power system network.
