This paper aims to improve a low-cost modular control device based on the IoT concept by integrating long-range LoRa communication technology. The LoRa communication technology enables the use of a modular control device in areas without implemented Internet and WiFi infrastructure.

This paper presents a deep neural network (DNN) approach designed to estimate the milk yield of Holstein-Friesian cattle. The DNN comprised stacked dense (fully connected) layers, each hidden layer followed by a dropout layer. Various configurations of the DNN were tested, incorporating 2 and 3 hidden layers containing 8 to 54 neurons. The experime...

Simple Summary This research aims to evaluate the possibility of introducing modern methods for the selection of dairy cattle in Serbia. A total of eight models were applied to estimate the genetic values and their accuracy based on the data of milk yield, milk fat yield, milk fat content, milk protein yield and milk protein content. A total of 604...

In recent years, there is a growing trend of developing diverse Industrial Internet of Things (IIoT) devices and systems to support the advancements in industrial systems known as the Industry 4.0. New devices and systems are often developed with connectivity capabilities, however there are many already functioning devices and systems that are init...

This paper proposes a conceptual solution for the smart production and processing of food products. Smart factories are the basis of the proposed concept. This proposed solution enables factories to produce and process food products to optimize production based on feedback from end users to reduce food losses. Reducing food losses would indirectly...

States of emergency that occur as a consequence of epidemic and pandemic spread of the disease (influenza, Covid-19) negatively affect all human activities. In states of emergency, various measures can be applied in order to reduce the potential risks to human health and life to a minimum. The most common measures refer to the interdiction on the w...

Upisom prve generacije 2002. godine, počelo je studiranje na studijskom programu Mehatronika na fakultetu tehničkih nauka u Novom Sadu (FTN). Uvođenjem ovog studijskog programa, FTN je postao prvi fakultet U Srbiji i regionu jugoistočne Evrope koji je studentima koji su izučavali gradivo iz oblasti Mehatronike i uspešno uradili sve predviđene obave...

Considering the great importance of groundwater quality for water supply, in the last decade, significant scientific attention has been devoted to nitrate reduction transformation pathways and nitrogen conservation in groundwaters in the form of ammonium. To evaluate and assess the ability of machine learning models to predict the ammonium concentr...

Industry 4.0 is a paradigm that enhances industrial automation systems with the recent advances in the domain of the Internet of Things (IoT), gaining new possibilities and providing new services. Traditional industrial machines do not have IoT capabilities, and in order to integrate such a machine into Industry 4.0, there is a need for an intermed...

The application of didactic setups is one of the commonly used teaching methods at schools and universities nowadays. By using the didactic setups, students are introduced to real components and real processes that take place in the industry. However, the students often need to use the didactic setups outside of regular teaching activities and at t...

Increasing the performance of all computing components enables the development of new architectures and platforms for data processing, sharing, distribution and storage of data. Speed, security and reliability of data transmission are essential parameters in industrial automation and therefore only those architectures/concepts that successfully mee...

Bespilotne letelice (eng. unmanned aerial vehicle, UAV) sve više postaju dostupne u civilne svrhe i često se upotrebljavaju u tandemu sa različitim tipovima kamera za dobijanje video zapisa. Pored toga, druga česta primena bespilotnih letelica je dostava paketa. U ovom radu je razmatran prilaz da se hvataljke za prenos predmeta koje se tradicionaln...

This paper describes the course Systems for Supervision and Process Visualization that is conducted at the undergraduate studies of Mechatronics at University of Novi Sad, the scope, tasks, labs and hands on activities. In addition, it presents the student evaluation of the course that provided valuable feedback for further improvements.

According to the LEAN philosophy, one of seven major losses incurred in the production process are errors in the quality. Any error in the products quality as a consequence has losses in the entire production process. Quick detection of the source of errors and causes of their occurrence are of vital importance for the management of production proc...

Food product traceability from harvesting, through food processing to the final food product and through the retailer to the end consumer is a significant process that has to ensure food quality and safety. The traceability enables the end consumer to get information from all previous stages of the food product, leading back to the food origin. In...

This study presents a wireless filter monitoring system (WFMS) for compressed air filters based on a very low power consumption microcontroller. Proposed system consists of two separate units (sensor and base), which constantly monitor filters. It is very easy to install in existing manufacturing systems, simple and efficient for production and use...

This paper presents an example of how a differential pressure sensor can be used to improve grasping of in-mold-labelling (IML) robots. In order to minimize mold-open time on injection molding machines, shorter operation time is desirable. To achieve this goal, an analysis of grasping labels using the in-mold-labelling robots was done with differen...

One of the most difficult and most important engineering tasks is the integration of a robot-manipulator into material handling, assembly, and production processes, offering the possibility of supervision and control. The knowledge and skills required for these kinds of tasks are purely mechatronic and, thus, multidisciplinary. This paper describes...

In home automation there is often a need for control of devices that have a built-in receiver for infrared communication with a remote controller. When trying to integrate such devices in a single control system, it is possible to substitute the remote controller with another infrared transmitter which automatically controls the device. This paper...

The collaborative design process supports the development of successful systems and products with a many participating engineers from a variety of disciplines. This kind of working environment lays stress on obtaining such multidisciplinary knowledge. Such efforts became an important element of capstone projects for students from different departme...

Food monitoring from its creation to its arrival to the consumer is a very important process, ensures food quality, consumers' health, and lowers expenses for each participant in the process. In the developed countries there are already systems for food monitoring through the entire logistics chain, i.e. food quality during transport, storage and s...
