It is a well-known fact that Turkey is on a seismically active region. In order to kick-off structural dynamics research in TOBB Economy and Technology University which would focus on improving earthquake response of structures, an experimental earthquake simulation setup and a three floor building model is created as a senior year graduation project. There were two main parts of the study; the first part is the design and integration of components of an earthquake simulation system. The second part is the ...
Design and implementation of low power interface electronics for vibration-based electromagnetic energy harvesters
Rahimi, Arian; Külah, Haluk; Muhtaroğlu, Ali; Department of Electrical and Electronics Engineering (2011)
For many years batteries have been used as the main power sources for portable electronic devices. However, the rate of scaling in integrated circuits and micro-electro-mechanical systems (MEMS) has been much higher than that of the batteries technology. Therefore, a need to replace these temporary energy reservoirs with small sized continuously charged energy supply units has emerged. These units, named as energy harvesters, use several types of ambient energy sources such as heat, light, and vibration to ...

Presents a study on the design and evaluation of two block coded modulation systems. One of the systems uses a binary construction and quadrature amplitude modulation. The other utilizes a ternary construction and phase modulation. The performance of the two coded schemes are compared theoretically with those of uncoded schemes of the same bandwidth, average power and transmission rate. The ternary scheme is also evaluated practically by computer simulations. Furthermore, the sub-optimum detection algorithm...

The design and development of high-efficiency interdigitated back contact (IBC) solar cells have been studied within the scope of this thesis. Developing a totally industry-compatible, lithography-free, high-throughput process flow for IBC cell fabrication was the main motivation of the thesis. For this, a detailed simulation study was conducted using Quokka 2 software to optimize the rear side cell geometry and understand the effect of bulk and layer properties on the device performance. After determining ...
Design and experimental analysis of mechanical force generators for performance improvement of machines
Ekinci, Mehmet Burak; Soylu, Reşit; Department of Mechanical Engineering (2019)
Recently, a novel overconstrained mechanism with favorable dynamic properties, namely the MFG (Mechanical Force Generator), has been proposed. This mechanism can provide a desired mechanical force, or power variation depending on the position of its input links. This power profile can be adjusted in order to improve the performance of a machine and its actuators that are connected to the MFG. In previous works, determination of an optimum power profile for the MFG and determination of the MFG design paramet...
