Microgrid Control Schemes And Current Trends For Sustainable Energy

2021-04-23T13:21:36+00:00

A microgrid is one of the improving concepts and creates the power grid works as smarter. Control technique in Microgrid working and operation is a key element for application and research. A microgrid is an aggregation of multiple distributed generators (DGs), energy storage systems, and loads. A microgrid can be operated in both islanding mode and grid-connected mode. Micro grid’s control is necessary to provide power quality, system stability, and also reliability. Most DG technologies, which can be installed in the microgrid, are not suitable to direct connection to the grid because of their power generation characteristics. Therefore, for the installation of these units in the microgrid, we need the power electronic converters. Hence, the main concern in the operation of the microgrid is to control the power electronics units. Microgrid’s control methods are different with respect to its structure that is mean that what type of microgrid exists for study, DC or AC microgrid or consolidation of them that is called hybrid microgrid. It is noticeable that control methods in the microgrid are also different from the point of view of control functions. For example, output power control of DGs, islanding detection, synchronization with the upstream grid, power quality, participation in the energy market and etc. Moreover, control methods of microgrid can be divided into two general categories such as control methods based on communication infrastructure and without communication link.

An Experimental and FEA approach to investigate the effect of LSP on the microstructure and corrosion resistance of Ti-17 titanium alloy.

2021-06-06T08:21:13+00:00

Ti-17 is a widely used material in the aircraft and marine industry while experiences severe environmental condition in its service life. Severe breakdowns happened to the marine vessels and other materials during its service life due to the corrosion. Therefore, to strengthen its material properties against electrochemical corrosion resistance, a novel technique laser shock processing has been employed. LSP is widely used for surface modification by improving its material properties. A simultaneous FEM analysis also conducted to validate the experimental results. An Nd: YAG (Neodymium-doped yttrium aluminum garnet) laser has been equipped with a 1064 nm wavelength. Three different laser energies 8J, 9J and 10J with laser power density 11.32 GW/cm², 12.73 GW/cm², 14.14 GW/cm² for 8J, 9J and 10J, respectively have been chosen. A 3 mm circular laser spot has been used with 50% overlapping rate. XRD, SEM, Vickers hardness tester, XRD sin² (2 ) technique were used to investigate the phase transformation, microstructure and grain refinement, micro hardness and compressive residual stress (CRS), respectively. Experimental results show that, a maximum -405 MPa compressive residual stress generated in the LSPed surface which is agreed by FEM and FEM shows that the affected depth is about 1500 m from the treated surface. Microstructure test reveals the original Ti-17 consists of a typical + structure along the grain boundaries. SEM observation shows that coarse grain has been refined after the LSP treatment. Severe plastic deformation observed in the treated surface. Microhardness also improved after LSP and maximum hardness -398 HV were reported. Electrochemical test were conducted in 3.5% NaCl solution in room temperature with a three electrode system. OCP, EIS and potentiodynamic polarization study shows that corrosion resistance, corrosion current and corrosion potential improve after LSP. This research shows that the deformation induced martensites and surface roughness at higher laser power energy outweigh the beneficial grain refinement and compressive residual stress and has detrimental effect on corrosion resistance.

2021-06-10T11:11:04+00:00

In the 21^st century, the internet has become a quicker platform through which crimes are reported to the public. Crime is an important topic and is of interest to us because of the consequences and penalties it attracts. This work the study is to show the pattern and crime rate in Nigeria. Then, show the relationships that exist between crime figures and employment status/gender by using canonical correlation analysis (CCA). Secondary method of Data collection was employed. The findings reveal Burglary as the most common crime type reported over the period, followed by Murder. The trend employed trend analysis in time series, correlation and Canonical Correlation Analysis with a statistical software called Minitab 18. However, the aim of analysis reveals no trend for Murder, upward trend for Armed Robbery and downward trend for both bribery/corruption and Burglary. For correlation studies, it reveals that there is a relationship among the pairs considered at 0.05 level of signiﬁcance and the CCA suggest variable (Burglary) on both ESG variables are significant (that is sex and employment status of the crime figures are significant than other SCR variables “Murder, Armed Robbery, Bribery and corruption”).

Application Programming Interface (API) Library for Nigerian Software Development Industry

2021-06-10T11:13:27+00:00

The concept of re-using functions or routines (or sometimes called libraries) built by the developer or a third party to address critical problems within applications by the developer without re-inventing the wheel is not new in software development. However, there are some extremely difficult situations in which an application must communicate with one or more other applications in order to share data/information without having prior knowledge of how such data/information is derived; thus, the name of such a process is Application Programming Interface (API).In the Nigerian software development industry, developers who build applications to access national critical data/information on a daily basis attempt to re-event the wheels where such capacity exists at the expense of cost and time, and are frequently confronted with limitations due to a lack of publicly re-usable functions, routines, or libraries that will enable access to such national critical data. This paper will offer a solution to this problem by providing a framework and an implemented application boilerplate that will allow Nigerian software developers to gain secure access to dozens of APIs that may target national critical data/information such as BVN, NIN, biometrics data, security data from security agencies, customs, NDLEA, immigration, licensing authorities and any other national critical data/information required by an application programmer without re-inventing the wheel thereby saving cost, time and removing limitations currently suffered by developers. The exploratory and explanatory research methodologies, as well as the Angular framework, were used to examine the impact of not reinventing the wheel. This work may be useful to programmers, API developers, researchers, security agencies, and any organization tasked with managing national critical data.

Trace Metal Studies on the Level of Zinc Content from Limboti Reservoir with Reference to Agriculture Context

2021-11-26T07:29:39+00:00

Limboti reservoir is situated near Limboti village of Loha Tehsil, Dist. Nanded of Maharashtra state. It is an Earth fill dam on the river Manar, engulfed with the different culture of agricultural land with soil pattern like little red soil, black cotton, sediments, fertilizers, bacteria from the livestock, food processing and various soil salts from irrigation drainage system. The metal pollutants are generally common in environment. There are different pollutants we always observe in agricultural soils and its occurrence, passing ways through the water defines the presence of natural as well as anthropogenic sources. However, these metals are in small quantities hence its referred as trace metals. The trace metals can occur naturally in the water but hardly ever at toxic level. The advanced culture of agriculture practices meanwhile contribute to containing waste, zinc covering material cause pollution in water body. Our emphasis is to identify quantitatively the concentration of zinc which is one of widespread essential micronutrient.

Source of zinc as trace element is observed in an aquatic system by galvanized steel material, zinc coated pipes used for irrigation, agricultural fertilizers, and other sources. Zinc is essential as a nutritional element for humans, plants, and animals, it is biologically significant. Present investigations, the Limboti reservoir near to Nanded city, also its wide applicability, hence we have selected this site for work on zinc and agriculture. Water samples were collected from the different three locations (Site-1, Site-2 and Site-3). The analysis carried out during period of February 2018 to January 2019 continuously. Zinc is studied by UV Spectrophotometer of Shimadzu UV1800, at wavelength of 535nm. Dithizone is widely useful and popular method applied for the systematic estimation of zinc. Maximum value of zinc was observed as 1.66mg/L and the minimum noted as 0.7mg/L.

Vandalism Of Monuments and Neglect: A Concern for Heritage Tourism

2021-12-08T06:22:40+00:00

The occurrence of vandalism in structures of historical and cultural value has been largely observed in urban environments. The destruction to these structures ultimately imposes challenges to historical and cultural tourism in particular. Local municipalities in urban cities are tasked with a responsibility of maintaining local infrastructure and essential services to support tourism activity. However, amongst the biggest constraints for local governments to meet these objectives is limited budgets, therefore leaving the cities with unpleasant aesthetics. This study determines the extent and forms of vandalism that exists in the city of Pietermaritzburg, South Africa and its implications to heritage tourism. The city is governed within the jurisdiction of Msunduzi Municipality housing many of South Africa’s heritage monuments that are integral to the city’s history, culture and multiplicity of tourism offerings. A review of online sources as well as visual and photographic methods were applied for data collection. The analysis revealed various forms of vandalism mainly concentrated in the central business district (CBD). These results suggest that residents are oblivious to the intrinsic and monetary value of historic monuments. The disjuncture between residents and monuments may be attributed to South Africa’s harrowing history of oppression as well as the lack of connection and sentimental value. On this basis, it is recommended that Msunduzi Municipality in collaboration with heritage agencies creates post-colonial monuments that are inclusive and transformational. In addition, it is suggested that aggressive educational initiatives are introduced on existing monuments.

A Novel Implementation of Secure and Efficient Biometric-Based Secure Access Mechanism for Cloud Services

2021-12-12T14:04:34+00:00

The demand for remote data storage and computation services is increasing exponentially in our data-driven society; thus, the need for secure access to such data and services. In this paper, we design a new biometric-based authentication protocol to provide secure access to a remote (cloud) server. In the proposed approach, we consider biometric data of a user as a secret credential. We then derive a unique identity from the user’s biometric data, which is further used to generate the user’s private key. In addition, we propose an efficient approach to generate a session key between two communicating parties using two biometric templates for a secure message transmission. In other words, there is no need to store the user’s private key anywhere and the session key is generated without sharing any prior information. A detailed Real-Or- Random (ROR) model based formal security analysis, informal (non-mathematical) security analysis and also formal security verification using the broadly-accepted Automated Validation of Internet Security Protocols and Applications (AVISPA) tool reveal that the proposed approach can resist several known attacks against (passive/active) adversary. Finally, extensive experiments and a comparative study demonstrate the efficiency and utility of the proposed approach

2022-02-24T08:41:05+00:00

The purpose of this study is to establish the impact of non-performing loans on the performance of commercial banks in Zimbabwe, during the multiple currency era for the 2009-2017 period. Understanding the role played by banks in the Zimbabwean economy, it is essential to carry out a study of this nature to point out key banking areas impacted by bad loans. The study make use of secondary data from a survey of 13 commercial banks through the Reserve Bank of Zimbabwe. Data for this study was collected from the Reserve Bank of Zimbabwe (RBZ) published financial accounts, Bank Licensing Supervision and Surveillance (BLSS) quarterly reports and the International Monetary Fund (IMF) Annual Article IV consultation reports. The Johansen Cointegration test was employed to analyze data, to examine the existence of a long-run relationship between the variables. The results revealed a negative impact of credit risk on banks return on equity. Management efficiency and loan loss provision ratios has a positive long-run effect on bank performance whilst interest income and loans and advances ratios has an adverse long-run effect. This is a reverse of the prior expectations and it is a result of the underlining macroeconomic conditions in the Zimbabwean economy that causes banks to misbehave in anticipation of the future risks. Furthermore, the study make use of the Vector Error Correction Model (VECM) to check for short-run dynamics and found out a negative in the coefficient value of the error correction term. This implies existence of forces that restores back the long-run equilibrium of the model from short-run movements. A conclusion was drawn that non-performing loans are a major cause of concern to changes in liquidity and banks’ lending behavior.

Do Gulf Cooperation Council Trade Determined By Geographical Proximity And Cultural Similarity?

2022-09-15T08:11:01+00:00

The aim of this paper is to examine the impact of cultural and geographic determinants on trade flows of the Gulf Cooperation Council (GCC) countries. For the methodology, we have used a gravity model to estimate the determinants of GCC exports and imports with 58 trading partners over the period 2000-2019. The findings show that the Fixed Effects Model (FEM) predicts that the effect of geographic proximity and cultural similarity on trade flows for GCC countries is insignificant. These results contradict the expected results of the gravity model. In addition, we extend the estimation of the gravitational model by using the Poisson pseudo-maximum likelihood with High-Dimensional Fixed-Effects (PPMLHDFE). The findings were impressive. We found that geographical distance and common language reduce GCC exports and imports. The colonial is an essential trading partner of the GCC countries.

You are what you pay: A Case Study in Venmo

2023-02-11T09:08:05+00:00

With the advent of the Internet Age, digital payments have become the cornerstone of the economy. From vendors on the street to billion dollar corporations, all entities accept payments through digital modes. Venmo, a mobile application by PayPal is popular for facilitating peer-to-peer digital transactions without a fee. Users can request or send money to other users by scanning a QR Code, or via a phone number or email address. While the primary purpose of the app is money transfer, Venmo goes a step ahead and adds a social component to it: users can add others as friends, like or dislike transactions, and even leave comments. Our study aims to understand privacy issues in using Venmo for monetary transactions. To this end, we examine the Venmo activity of N = 10 users, and conduct follow-up semi-structured interviews with them. We discover that transactions on Venmo are public by default, and need specific user effort to make them private. These transactions can potentially reveal information about a user's habits, preferences, financial circumstances, family and friends. Friend lists are publicly visible to others. The privacy settings section of the application is obscure and hard to find. Based on our digital investigation and user study, we provide a set of recommendations that can improve user privacy in payment apps, even those that have a social component.

2023-02-11T09:07:05+00:00

Random numbers are critical as they generate the keys which are used in encrypting the data and are generated by a process, where the outcome is unpredictable and cannot be reproduced. Even in cases, where the input is precisely known, there will be no clear knowledge on which portion of input is observable and these issues may be addressed by appropriate sensitivity analysis in assignment problems which in turn support decision making. In this paper, the associated costs are taken as Randomly Generated Triangular Fuzzy Numbers (TrFNs), Robust Ranking Technique is used for defuzzification, and Hungarian method is used in determining the fuzzy optimal solution and is related with the original fuzzy assignment problem. This study is used to identify how much variations in the input values for a given variable impact the results for a mathematical model, and it is proposed to use the decision making methods for solving multi-criterion group decision making processes.

India is traditionally an agriculturally based country. The population of India growing tremendously and touches the world’s first position within few years. So, it is evident that the existing agriculture system does not fulfil the future demand. Hence, it is necessary to adopt smart farming technology in Indian agriculture systems and also encourage the farmers to improve their crop yielding and to predict crop as well as less utilisation of water resources. Therefore, a literature review is very much needful to focus on recent development trends in smart farming technologies in agriculture such as Internet of Things (IoT), Data Mining Techniques, Machine learning Algorithms and Cloud Computing. This paper presents different emerging systems including IoT and Mobile Agent Systems which are using in the worlds agriculture system to predict crop yield, with minimum water utilisation and forecasting whether such as rainfall, temperature etc. And also, this paper presents advantages and limitations of the different techniques along with some recommendations to implement in agriculture system thereby it leads to improve economic benefits to the famers.

Conjoint Coupling Lessening in Multiband MIMO Antenna Using Cross-Slot Fractal Multiband EBG in the E-Plane

2023-07-05T10:51:51+00:00

In this paper, provided a technical description of a research study involving the design and implementation of a multiband electromagnetic band gap (EBG) structure and a multiband multiple-input and multiple-output (MIMO) antenna for mutual coupling reduction. Here's a brief explanation of the terms and concepts used in the description. Electromagnetic band gap (EBG) structure is periodic structure made of dielectric or metallic materials that act as a filter for electromagnetic waves. It has the ability to prohibit the propagation of certain frequencies at 5.7 GHz, 7.5 GHz, and 10 GHz frequencies. and allows others to pass through. Multiband EBG structure: An EBG structure that can filter multiple frequencies simultaneously. MIMO antenna of that uses multiple antennas at the transmitter and receiver to improve the communication performance. It allows for multiple data streams to be transmitted and received simultaneously, which increases the data rate and reliability of the communication system. Mutual coupling: A phenomenon that occurs when the electromagnetic fields of two antennas interfere with each other, leading to degradation in communication performance. Envelope correlation coefficient: A metric used to measure the similarity of the signals received by two antennas in a MIMO system. It indicates how correlated or independent the signals are. Channel capacity loss: A measure of the reduction in the maximum achievable data rate due to the presence of mutual coupling in a MIMO system.

Particle Swarm Optimization based Communication and Fault Tolerant Clustering Protocol for Wireless Communication

2023-08-09T07:04:23+00:00

In wireless sensor networks (WSNs), energy efficiency can be achieved through the implementation of a variety of various strategies, the sole purpose of which is to lower overall energy consumption. However, fault tolerance and energy balancing give equal importance for enhancing the network lifetime. A shortest path is what defines for the Base Station (BS), although it is important to have both. Clustering is one of the effective approaches for wireless sensor networks and has been believed to be one of the best ways to save energy in wireless sensor networks. Failures can occur as a result of excessive overload, which causes more energy to be consumed by the cluster heads (CHs) in a cluster-based wireless sensor network (WSN) in order to receive and aggregate the information from member sensor nodes. The choice of CHs has been an important factor in the amount of energy that sensor nodes have needed to use in order to make WSNs last longer. Particle Swarm Optimization (PSO) is one of the intelligent strategies that are proposed in "An Energy Efficient Unequal fault tolerant clustering approach," also known as "PSO-FL-C," with the purpose of lowering the amount of energy that is used. An optimal MCH-MDA selection technique has been given in the approach. This method makes use of the fitness values, and it evaluates these values based on the PSO to find two optimal nodes in each cluster that will operate as the Master Data Aggregator (MDA), and the MCH. The selected MCH is the only one who can collect the data from the cluster members, and the MDA is the one who is responsible for receiving the data from the MCH before sending it on to the BS. As a result, there is a decrease in the MCH overhead. During times of intense data transfer, overhead controls are implemented through the utilization of energy-efficient time division multiple access (EE-TDMA) scheduling. In order to demonstrate the superiority of the suggested approaches based on a variety of performance indicators, simulations will be run, and the results will be compared with those of the existing methods.

Enterprise Resource Planning’s Fundamental Concepts of Growth of the User Satisfaction

2024-01-27T11:57:24+00:00

ERP package developers, as well as the organisations interested in implementing ERP systems, must determine what features should be included in an ERP package for TEIs. Enterprise resource planning (ERP) aims to improve the overall efficiency of the system as well as the efficiency of the business. It also aims to improve communication and coordination as well as task efficiency. Having an enterprise resource planning (ERP) system in place that is strategically oriented toward directly responding to expanding consumer demands and seizing market opportunities as they arise, is critical nowadays ERP is simply seen as a tool for winners, who use it to efficiently obtain critical information and act on it as soon as possible. ERP systems differ from other types of systems in that they are pre-packaged software solutions rather than custom-built systems. Therefore, they are pre- loaded with assumptions and procedures regarding the business operations of the businesses in which they are used. Enterprise resource planning (ERP) success is defined as the successful implementation of such systems to improve operational efficiency and effectiveness. The advantages of scientific ERP solutions are numerous and varied. We can say that an enterprise system streamlines a company's information flows and offers management immediate access to a wealth of real-time operating info. For a lot of businesses, these advantages have translated into remarkable gains in pace as well as efficiency.
