Kutatásunk célja egy olyan komplex hardver- szoftverrendszer létrehozása volt, amelynek segítségével megállapítható a technika elsajátításának hatékonysága labdás játékok esetén például egy kézilabdázó dobási pontosságának és dobóerejének mérése révén. A szemből és oldalnézetből készített felvételek alapján, a mozgó objektum képkockánkénti elmozdulásából számítható a labda sebessége és pozíciója a képelemzés eszközeinek segítségével. Különös figyelmet fordítottunk az eszköz költséghatékony megvalósítására, valamint fontosnak tartottuk az egyszerű kezelhetőséget a telepítés és a mérés folyamán egyaránt. Mindezt a megfelelő hardver és szoftver technológiák kiválasztásán túl az is biztosítja, hogy nem igényel külön hardver eszközt a kezelése, mivel az edzők vagy a testnevelők saját mobileszközükről férhetnek hozzá a rendszer szolgáltatásaihoz. Az egyszerű kezelhetőséget a telepítés és a mérés folyamán egyaránt szem előtt tartottuk. Ez a technológia mind módszertani szempontból, mind motivációs eszközként is figyelmet érdemel, akár edzéseken, akár az iskolai testnevelés órákon. A fenti szempontok figyelembevételével a Raspberry Pi 3B+, a hozzá csatlakozó Raspberry Pi Camera V2-es modelljére (Raspberry Pi) és az ESP32 Cam-ra (ESP32), mint hardver komponensekre esett a választásunk. A kezelőfelületet pedig egy webes alkalmazás biztosítja, amelyen keresztül megfelelő hitelesítési folyamatot követően elérhetők a rendszer szolgáltatásai. ----- Developement and measurement of ballplayers’ motoric skills ----- Our research aimed to create a complex hardware-software system that can be used to determine the effectiveness of the technique in ball games, for example by measuring the throwing accuracy and throwing power of a handball player. Based on the shots taken from the front and side views, the speed and position of the ball can be calculated from the displacement of the moving object frame by frame using image analysis tools. We paid special attention to the cost-effective implementation of the device, and we considered it important to be easy to use during both installation and measurement. In addition to selecting the right hardware and software technologies, this is ensured by the fact that it does not require a separate hardware device to manage, as coaches or physical educators can access the system's services from their mobile devices. Ease of use was kept in mind during both installation and measurement. This technology deserves attention both from a methodological point of view and as a motivational tool, whether in training or school physical education classes. Considering the above considerations, we chose the Raspberry Pi 3B+ with a Raspberry Pi Camera V2 model and the ESP32 Cam as hardware components. The user interface is provided by a web application through which the system services can be accessed after a proper authentication process.

AbstractThis work is focused to carry out the investigation of wavelength division multiplexing (WDM) approach on free space optical (FSO) transmission systems using Erbium Ytterbium Doped Waveguide Amplifier (EYDWA) integrated as post-or pre-amplifier for extending the reach to 30 Km for the cost-effective implementation of FSO system considering weather conditions. Furthermore, the performance of proposed FSO-wavelength division multiplexing (WDM) system is also evaluated on the effect of varying the FSO range and results are reported in terms of Q factor, BER, and eye diagrams. It has been found that, under clear rain the post-amplification was performed and was able to reach transmission distance over 27 Km, whereas, the FSO distance has been limited at 19.5 Km by using pre-amplification.

In recent years, there has been increased focus on fan-out wafer level packaging with the growing inclusion of a variety of fan-out wafer level packages in mobile products. While fan-out wafer level packaging may be the right solution for many designs, it is not always the lowest cost solution. The right packaging choice is the packaging technology that meets design requirements at the lowest cost. Flip chip packaging, a more mature technology, continues to be an alternative to fan-out wafer level packaging. It is important for many in the electronic packaging industry to be able to determine whether flip chip or fan-out wafer level packaging is the most cost-effective option. This paper will compare the cost of flip chip and fan-out wafer level packaging across a variety of designs. Additionally, the process flows for each technology will be introduced and the cost drivers highlighted. A variety of package sizes, die sizes, and design features will be covered by the cost comparison. Yield is a key component of cost and will also be considered in the analysis. Activity based cost modeling will be used for this analysis. With this type of cost modeling, a process flow is divided into a series of activities, and the total cost of each activity is accumulated. The cost of each activity is determined by analyzing the following attributes: time required, labor required, material required (consumable and permanent), capital required, and yield loss. The goal of this cost comparison is to determine which design features drive a design to be packaged more cost-effectively as a flip chip package, and which design features result in a lower cost fan-out wafer level package.

Despite the recent interest in health rights litigation, there has not yet been a study specifically addressing and comparing the justiciability of the right to health in two diverse contexts such as South Africa and Switzerland from the point of view of determining whether the essential components of the right to health under international law have been referred to in the formulation of complaints and in judgments handed down by the courts. The respective constitutional provisions incorporating the right to health as well as pertinent health rights cases were identified before analysing the similarities and differences relating to the essential components of the right to health. The findings support more frequent reference to the normative components of the right to health throughout domestic judicial proceedings in order to further the advancement and effective implementation of the right to health, not only in South Africa and Switzerland but more broadly.

Managing the energy efficient and conserving it intelligently for appliances is very much important. On the other side, it may be possible events mistake cause while reading on energy meter, monitoring and keeping track of your electricity consumption for verification is a tedious task today. Our main objective of measuring the power consumption at homes using IOT with raspberry pi during period time, which can be controlled as well monitored through the raspberry pi across the IOT. We used Python programming language to control raspberry pi. It's based on raspbian which is operating system for all models of the raspberry Pi that subject to linux system. As we say before raspberry pi has inputs and we use it for connecting the supply, energy meter and load such as a lamp or Drill. The energy meter is connected to the raspberry pi. This allows user to easily check the energy usage along with the cost charged online using a simple web application connecting to Wi-Fi. Thus, the energy meter monitoring system allows consumer to effectively monitor electricity meter readings and bill amount in an easy way. It presents a low cost and flexible energy meter monitoring system using IOT. In addition, we use camera which is called camera pi. Camera pi takes picture from meter reading and communicates to consumer via email. All information on the energy meter screen will be taken by raspberry pi module. Using this data, the raspberry pi will calculate the bill amount then send to the consumer by email. Finally, this project will help for the proper and accurate reading of the billing process automatically. Also, it enables consumer to save the money for a long time. This technology offers new and exciting opportunity to reduce the work of workers.

Object sorting is a very common industrial application but at the same time it is a tiresome process as handling so many objects is a menial task which is not so promising in maintaining consistency and thereby arising quality issues. Object sorting, if done manually, is not only time consuming but also it seems to be an uphill task pragmatically. Nowadays amid various technological advancements, industries have become fully automated so an automated sorting system is essentially required to replace this conventional system of manual sorting knowing that this process can be made completely autonomous by properly channeling the use of technology. The main objective of this paper is to propose a smarter, intelligent and cost-effective object sorting system which categorizes the objects based on their respective color and will place them at their designated locations to minimize the cost and optimize the productivity. We have implemented the sorting system using Raspberry pi (an open-sourced Linux based board) interfaced with a camera module along with some side electronic circuitry such as servo motors and sensors. The color recognition is done using the IBM Watson visual recognition model where we have uploaded the dataset of captured images. For picking and sorting the objects, we have made use of a robotic arm that will rotate with the help of servo motor up to certain angles.

The fundamental understanding of transition metal oxides nanowires’ crystal growth to control their anisotropy is critical for their applications in miniature devices. However, such studies are still in the premature stage. From an industrial point of view, the most exciting and challenging area of devices today is having the balance between the performance and the cost. Accordingly, it is essential to pay attention to the controlled cost-effective and greener synthesis of ultrathin TMOS NWs for industrial optoelectronic applications. This chapter provides a comprehensive summary of fundamental principles on the preperation methods to make dimensionality controlled anisotropic nanowires, their crystal growth studies, and optical and electrical properties. The chapter particularly addresses the governing theories of crystal growth processes and kinetics that controls the anisotropy and dimensions of nanowires. Focusing on the oriented attachment (OA) mechanism, the chapter describes the OA mechanism, nanocrystal’s self-assembly, interparticle interactions, and OA-directed crystal growth to improve the state-of-the art kinetic models. Finally, we provide the future perspective of ultrathin TMOS NWs by addressing their current challenges in optoelectronic applications. It is our understanding that the dimension, and single crystallinity of nanowires are the main contributors for building all functional properties, which arise from quasi-1-D confinement of nanowire growth.

Both open die and closed die powder compact forging can be used for the consolidation of Ti and pre-alloyed Ti 6Al 4V powders produced by a hydride-dehydride (HDH) process. The approach used is initial cold or warm compaction into cylindrical shapes, or into a specific pre-form shape appropriate for achieving a particular final forged shape. The economic benefit is near net-shape processing with minimum machining required after forging. Manufacturing costs are also minimised by forging a compact, with a sufficiently high enough density, in air, without a protective atmosphere. The challenge, from a manufacturing point of view, is the operation of a manufacturing route which gives rapid and qualified compaction to meet production demands and batch sintering to achieve a high enough density prior to final forging to shape. In addition to this the final product has to have the right level of mechanical properties. This paper reviews some key findings from powder compact production, through to sintering and forging. These will be presented in terms of alpha-beta phase distribution in the microstructure, the degree of porosity, heat treatment and their effects on mechanical properties.
