This paper deals with the online control of a redundant flexible link manipulator to achieve minimum oscillations using the redundancy resolution technique. Different redundancy resolution techniques proposed and used for rigid link manipulators are tested for their use in the case of…

Modeling, Simulation and Prediction of Vehicle Crashworthiness in Full Frontal Impact

2023

Vehicle crashworthiness assessment is critical to help reduce road accident fatalities and ensure safer vehicles for road users. Techniques to assess crashworthiness include physical tests and mathematical modeling and simulation of crash events, the latter is preferred as mathematical modeling is generally cheaper to perform in comparison with physical testing. The most common mathematical modeling technique used for crashworthiness assessment is nonlinear Finite Element (FE) modeling. However, a problem with the use of Finite Element Model (FEM) for crashworthiness assessment is inaccessibility to individual researchers, public bodies, small universities and engineering companies due to n…

PRACTICAL APPLICATION OF ADVANCED CONTROL : An evaluation of control methods on a Quanser AERO

2018

Master's thesis Mechatronics MAS500 - University of Agder 2018 In the past years, rotorcraft have received much attention in our society. These provide great accessibility and are utilized in many areas of application. The complex dynamics of rotorcraft make them di cult to control, and the applications demand stable, safe, and agile devices. This thesis investigates the use of advanced control methods and evaluates their e ectiveness using a 2DOF (pitch and yaw) ' ight control experiment-platform'; the Quanser AERO. The main goal of the project is development and evaluation of angular-position controllers for the AERO, using conventional and advanced control theory. This includes cascade P…

A Perspective Review on Integrating VR/AR with Haptics into STEM Education for Multi-Sensory Learning

2022

As a result of several governments closing educational facilities in reaction to the COVID-19 pandemic in 2020, almost 80% of the world’s students were not in school for several weeks. Schools and universities are thus increasing their efforts to leverage educational resources and provide possibilities for remote learning. A variety of educational programs, platforms, and technologies are now accessible to support student learning; while these tools are important for society, they are primarily concerned with the dissemination of theoretical material. There is a lack of support for hands-on laboratory work and practical experience. This is particularly important for all disciplines related …

Cutaneous Side Effects of Mask Wearing and from the COVID-19 Vaccines

2022

Priekšvēsture: 2019. gada nogalē Vuhānā, Ķīnā, uzliesmojis nezināma vīrusa uzliesmojums ātri izplatījās, un 2020. gada 11. martā PVO pasludināja COVID-19 par globālu pandēmiju. Tāpēc valstis visā pasaulē ieviesa jaunus valdības ierobežojumus. Šī iemesla dēļ sejas masku nēsāšana un vakcinācija pret koronavīrusu pagājušajā gadā kļuva par universālu tematu. Tas radīja jaunas dažādas nevēlamas ādas reakcijas un ādas izskata izmaiņas. Mērķis: Šī pētījuma mērķis bija novērtēt sejas masku un vakcinācijas izraisītās blakusparādības uz ādas un ieteikt profilaksi. Turklāt pētījumam būtu jāpalīdz izprast dažādu faktoru sakarības par to, kā tie ietekmē ādas reakciju iznākumu. Materiāli un metodes: Izma…

Meta-analytical definition and functional connectivity of the human vestibular cortex.

2012

Contrary to most other sensory systems, no consensus has been reached within the scientific community about the exact locations and functions of human cortical areas processing vestibular information. Metaanalytical modelling using activation likelihood estimation (ALE) for the integration of neuroimaging results has already been successfully applied to several distinct tasks, thereby revealing the cortical localization of cognitive functions. We used the same algorithm and technique with all available and suitable PET and fMRI studies employing a vestibular stimulus. Most consistently across 28 experiments vestibular stimuli evoked activity in the right hemispheric parietal opercular area …

Do young readers have fast access to abstract lexical representations? Evidence from masked priming

2014

Although there is consensus that adult readers have fast access to abstract letter/word representations, the developmental trajectory of such access has not been mapped out yet. To examine whether developmental readers have rapid access to abstract representations during the early stages of word processing, we conducted a masked priming lexical decision experiment with two groups of young readers (third and fifth graders) and a group of young adults. We selected two types of words: (a) words composed of cross-case letters that are visually dissimilar (DIS words; e.g., arte/ARTE [Spanish for art]) and (b) words composed of cross-case letters that are visually similar (SIM words; e.g., vivo/V…
