Microservices‐based databank for Turkish hazelnut cultivars using IoT and semantic web technologies

SummaryInformation and communication technologies (ICTs) can play a crucial role in facilitating access to comprehensive information on the quality standards of Turkish hazelnut cultivars. In this regard, this study introduces a Hazelnut Databank System (HDS) that utilizes the microservices architecture, an integrated software system supported by the Internet of Things (IoT) and semantic web, to categorize Turkish hazelnut cultivars. The study focuses on developing microservices using various programming languages and frameworks. Specifically, C# on the .NET Core Framework was used for both microservices and the web‐based application implemented through the ASP.NET Core MVC Framework. Mobile‐based software applications were created using Xamarin. Forms, and the IoT application was developed using the Python programming language. The data storage is facilitated through the MS SQL Server database. Additionally, the study incorporates the implementation of a hazelnut species classification system using the DNN + ResNet50 machine learning model, achieving an impressive accuracy rate of 95.77%. The overall usability of the system was evaluated, resulting in a score of 42 out of 50. By providing detailed information on Turkish hazelnut cultivars, the HDS has the potential to greatly improve hazelnut production quality in Turkey and increase awareness of hazelnut agriculture among relevant stakeholders.

Comparative analysis of performance of ASP.NET Core MVC and Symfony 4 programming frameworks

The article presents a comparative analysis of popular ASP.NET Core MVC and Symfony 4 frameworks. Two web applications, containing the same functionalities and acting as a simple system for managing articles, were implemented in these technologies. The applications underwent time performance tests during typical operations performed by means of a simple form such as entering, editing, viewing and deleting data. These actions were performed automatically using commands from the Puppeteer library. The listed operations were repeated 10, 100 and 1,000 times in order to obtain precise mean times. On the basis of the obtained results, it was difficult to clearly state which of the compared programming tools is better. The ASP.NET Core MVC framework coped much better with two time-consuming operations, i.e. entering and editing data. Its results in this regard (the average from 1,000 repetitions) were respectively approximately 28% and 25% better compared to the Symphony 4 framework. However, for the two less time-consuming operations, i.e. displaying and deleting articles, the Symphony 4 framework proved to be considerably better. Its results with regard to displaying and deleting articles (the average for 1,000 measurements) were respectively 15% and 36% lower compared to the other of the tested frameworks.

PLAFIR: aplicativo web para planejamento financeiro rural

Objetivo. A diversificação rural é um meio para que agricultores familiares prosperem ou até mesmo não pereçam. Contudo, decidir por uma nova atividade rural pode se tornar um trabalho árduo. O objetivo deste trabalho é desenvolver um Sistema de Informação que auxilie o agricultor na tomada de decisão por meio de indicadores financeiros.Método. Foi aplicado um questionário a vinte agricultores familiares do Oeste Paranaense, com abordagem quantitativa, e realizada uma pesquisa bibliográfica e documental para verificar os Sistemas de Informação disponíveis no mercado. Posteriormente, foi elaborado um projeto de software, utilizando elementos da UML, e como framework de desenvolvimento o ASP.NET Core MVC 1.1, com banco de dados PostgreSQL 9.5. A IDE utilizada para desenvolvimento foi o Microsoft Visual Studio 2015 Community Edition. Os testes foram realizados em ambiente Linux com Ubuntu 14.04, Apache 2 e navegador Chrome 55.Resultados. A implementação do projeto de software resultou no aplicativo denominado de Planejamento Financeiro Rural (Plafir). Este é um aplicativo web que auxilia na tomada de decisão, quando o agricultor decide investir em uma nova atividade rural. Com base em modelos financeiros pré-cadastrados no sistema por técnicos agrícolas e uma tabela de insumos com preços atualizados, o agricultor pode selecionar determinado modelo, simular a produção e conferir os resultados financeiros.Conclusões. A agricultura familiar está desprovida de Sistemas de Informação para a tomada de decisão e o aplicativo Plafir atende ao objetivo proposto neste estudo, contribuindo para a seleção de uma nova atividade rural.

INTERNACIONALIZACIJA I LOKALIZACIJA WEB APLIKACIJE RAZVIJENE KORIŠĆENJEM ASP.NET CORE MVC FRAMEWORK

U okviru rada je izvršena analiza lokalizacije i internacionalizacije u okviru Microsoft tehnologija. Kreirana je web aplikacija korišćenjem ASP.NET Core MVC frameworka, a u procesu pravljenja iste prezentovani su pojmovi lokalizacije i internaciona­lizacije. Pošto je .NET Core sam po sebi relativno novi koncept u okviru Microsoft tehnologija početni deo rada se bavi samim razvojem te tehnologije. Zatim je objaš­njeno kako u okviru .NET Core korišćenjem MVC frame­worka možemo da kreiramo Web aplikaciju. Na kraju se u radu objašnjavaju tehnologije i alati koji se koriste za internacionalizaciju i lokalizaciju.
