Abstract

The PicOps (existing device) has been recently developed in order to count the number of fired shots from a weapon, based on the undergone shock wave analysis. The present work proposes a concept called "Testbench", able to test the cababilities of the PicOps, without the need of an actual weapon.

Abstract

Grotere game-development bedrijven hebben nood om op voorhand te weten of een nieuwe game kan aanslaan bij het grote publiek. Hiervoor is een leuke gameplay zeer belangrijk. Om nieuwe gameplay uit te testen worden prototypes gemaakt. Deze prototypes kunnen zeer snel gemaakt worden aangezien weinig tijd wordt besteed aan de grafische aspecten, foutafhandeling, speciale gevallen,.... Er wordt voor de prototypes gewerkt in Unity3D.Voor een aantal technologieën werd onderzocht of deze kunnen bijdragen tot een vernieuwende gameplay. Sommige van de onderzochte technologieën moesten eerst nog geïntegreerd worden in Unity3D. Wanneer een technologie of meerdere technologieën samen aanleiding gaven tot een mogelijke nieuwe gameplay, is hiermee een prototype gemaakt.Er zijn twee technologieën onderzocht waarmee 2D-animaties van Adobe Flash gebruikt kunnen worden in Unity3D, uniSWF en Rad Game Tools: Iggy. De twee technologieën zijn met elkaar vergeleken om te weten te komen welke de beste resultaten gaf. Dit is gebeurd door een aantal simpele animaties te gebruiken in Unity.Er zijn tests uitgevoerd om de nauwkeurigheid van de accelerometer en gyroscope van een smartphone te testen. Hiermee is getest of het mogelijk is om enkel met deze twee sensoren de positie en oriëntatie in een ruimte te volgen.Er is een racegame prototype gemaakt met drie onderzochte technologieën. Het laat de gebruiker toe om dynamisch racetracks te maken met behulp van GPS-coördinaten, opgenomen met een smartphone. De coördinaten worden gebruikt met de Road/Path Tool om een racetrack te genereren in Unity. Ook werd er multiplayer-functionaliteit toegevoegd, met behulp van een photonserver.Als laatste zijn de mogelijkheden van een device, dat hersengolven kan meten, getest. Hiervoor is een integratie in Unity gemaakt en de meetwaarden zijn gebruikt in een Unity-prototype. Larger game-development companies have the need to know in advance whether a new game can appeal to the general public. A fun gameplay is very important for this. Prototypes are made to test new gameplay. These prototypes can be created very quickly since little time is spent on the graphic aspects, error handling, special cases,.... The prototypes are created with Unity3D.A number of technologies were examined to check whether they could contribute to an innovative gameplay. Some of the investigated technologies had to be integrated into Unity3D. When a technology or multiple technologies together gave rise to a possible new gameplay, they were used in a prototype.Two technologies which allow the use of 2D-animations from Adobe Flash in Unity3D were examined, uniSWF and Rad Game Tools: Iggy. The two technologies were compared to find out which gave the best results. This was done by using a number of simple animations in Unity.Tests have been conducted to check the accuracy of the accelerometer and gyroscope of a smartphone. This was examined by determining whether it is possible to determine the movement and orientation of the smartphone in a space, using these two sensors.A racing game prototype has been made with three investigated technologies. It allows the user to dynamically create racetracks using GPS coördinates, recorded with a smartphone. The coördinates are used with the Road / Path Tool to generate a racetrack in Unity. Multiplayer-functionality was added as well, using a photonserver.Lastly, the capabilities of a device that can measure brain-waves, were tested. An integration for Unity has been made for this and the readings were used in a Unity-prototype.

Abstract

Micro-electro-mechanical system (MEMS) devices are widely used for inertia, pressure, and ultrasound sensing applications. Research on integrated MEMS technology has undergone extensive development driven by the requirements of a compact footprint, low cost, and increased functionality. Accelerometers are among the most widely used sensors implemented in MEMS technology. MEMS accelerometers are showing a growing presence in almost all industries ranging from automotive to medical. A traditional MEMS accelerometer employs a proof mass suspended to springs, which displaces in response to an external acceleration. A single proof mass can be used for one- or multi-axis sensing. A variety of transduction mechanisms have been used to detect the displacement. They include capacitive, piezoelectric, thermal, tunneling, and optical mechanisms. Capacitive accelerometers are widely used due to their DC measurement interface, thermal stability, reliability, and low cost. However, they are sensitive to electromagnetic field interferences and have poor performance for high-end applications (e.g., precise attitude control for the satellite). Over the past three decades, steady progress has been made in the area of optical accelerometers for high-performance and high-sensitivity applications but several challenges are still to be tackled by researchers and engineers to fully realize opto-mechanical accelerometers, such as chip-scale integration, scaling, low bandwidth, etc.

Abstract

Despite being one of the most popular sports worldwide, basketball has received limited research attention compared to other team sports. Establishing a strong evidence base with high-quality and impactful research is essential in enhancing decision-making processes to optimize player performance for basketball professionals. Consequently, the book entitled Improving Performance and Practice in Basketball provides a collection of novel research studies to increase the available evidence on various topics with strong translation to practice in basketball. The book includes work by 40 researchers from 16 institutions or professional organizations from 9 countries. In keeping with notable topics in basketball research, the book contains 2 reviews focused on monitoring strategies to detect player fatigue and considerations for travel in National Basketball Association players. In addition, 8 applied studies are also included in the book, focused on workload monitoring, game-related statistics, and the measurement of physical and skill attributes in basketball players. This book also has a strong focus on increasing the evidence available for female basketball players, who have traditionally been under-represented in the literature. The outcomes generated from this book should provide new insights to inform practice in many areas for professionals working in various roles with basketball teams.

Abstract

Due to the ever-expanding applications of micro/nano-electromechanical systems (NEMS/MEMS) as sensors and actuators, interest in their development has rapidly expanded over the past decade. Encompassing various excitation and readout schemes, the MEMS/NEMS devices transduce physical parameter changes, such as temperature, mass or stress, caused by changes in desired measurands, to electrical signals that can be further processed. Some common examples of NEMS/MEMS sensors include pressure sensors, accelerometers, magnetic field sensors, microphones, radiation sensors, and particulate matter sensors. Despite a long history of development, fabrication of novel MEMS/NEMS devices still poses unique challenges due to their requirement for a suspended geometry; and many new fabrication techniques have been proposed to overcome these challenges. However, further development of these techniques is still necessary, as newer materials such as compound semiconductors, and 2-dimensional materials are finding their way in various MEMS/NEMS applications, with more complex structures and potentially smaller dimensions.
