Incompetent design of prosthesis for amputees inflict pain in muscles and bones contingent to the prosthesis. Simulation models mimicking human movement promise a prosthesis with improved movement capability for amputees. Musculoskeletal models enable better anticipation of prosthesis contributions to the human musculoskeletal system during walking movement. In this paper, we apply a simulation of musculoskeletal model on an amputated human model with a prosthesis using Gaussian Process Regression Machine Learning Predictor and deep reinforcement learning. The performance of two versions of a prosthesis, one being a simpler version (passive prosthesis) and one being relatively better version (active prosthesis) are evaluated and compared to that of a healthy human model.

The primary cause for road accidents is indicated as the unawareness state of the driver which is the result of being drowsy or distracted. Therefore, it is required for the researchers to design systems that detect drowsiness from camera and alert the driver. There are different deep learning architectures that learn the hidden relations between patterns according to their approaches for processing input data. In this paper, the performances of adopting spatial + temporal and spatio-temporal architectures are investigated through detecting driver drowsiness. For spatial + temporal approach, 2 dimensional ResNet-34 is used along with bidirectional LSTM while spatio-temporal architecture consists of 3 dimensional ResNet-34 inflated from 2 dimensional version followed by fully connected layers. The experiments are performed on NTHU Driver Drowsiness Detection dataset and performance of capturing temporal relations is analyzed for both cases. Experiments show that spatial + temporal approach is superior than spatio-temporal approach in terms of both accuracy and speed.

The UV (ultraviolet) based sensors identify the missiles with an algorithm that it runs by visually detecting the UV signature of the hot missile exhaust and extracting the threat features from these images. These features can be used in algorithm improvements by measuring with UV sensors placed on the ground projection of the missile flight route in live missile tests where missiles are fired to a hot target. However, live missile tests are difficult and costly processes. In addition, it is not possible to take measurements with UV sensors from every angle and range required in these tests. For these reasons, it is important to convert the UV signatures obtained as a result of firing the stationary missile engine in a suitable environment into missile signatures approaching towards the UV sensors. Within the scope of this study, the regression studies aimed to convert the UV signatures (static missile signature) taken from the fixed engine burning tests of various missiles into the UV signatures (dynamic missile signature) of the missiles approaching towards the UV sensors are summarized.

Computational imaging aims to extend the capabilities of conventional imaging systems by extracting richer and more meaningful information through multiple captures or by modifying the camera’s sensors and optics. In this paper, a joint focus stacking and high dynamic range (HDR) imaging method is proposed to extend the limited depth of field and dynamic range of a typical camera. The proposed method acquires a set of input images from a camera array with varying exposure and depth of field, and performs focus stacking under exposure diversity. Experimental results show significant improvement in the dynamic range and depth of field of the final focus-stacked HDR image. Additionally, the proposed method effectively handles the ghosting artifacts during the fusion process.

In this study, a new multilayer optical filter structure is designed with different cells of the Fibonacci series. The number of reflection and transmission bands of the filter can be adjusted by changing the repetition number of the blocks forming the filter. A designed filter structure, with adjustable channel feature, will be used as an alternative to Dense Wavelength Division Multiplexer (DWDM) filters needed in current optical communication systems.

Terahertz (THz) communication, which can provide a significant benefit to the developing communication technologies today, comes along with many problems. The most important of these problems are the high path loss and the direct line of sight (LOS) requirement in most of the communication schemes. Reconfigurable intelligent surface (RIS) designs, which can be brought as a solution to the line of sight requirement have been proposed in this research. The unit cells forming these surfaces cannot be designed using metal materials due to the characteristics of electromagnetic waves with THz frequency. Graphene material, according to its controllable surface impedance properties, provides both sufficient reflection conditions and can be used to create units with different reflective phase values with varying impedance values to create the RIS structure. In this study, a certain reflection phase range was obtained on a designed RIS unit cell and RIS structures that can direct the incoming plane wave to various angles using this unit were designed and simulated in CST Microwave Studio 2019 program.
太赫兹(THz)通信对当今通信技术的发展具有重要意义，但同时也存在许多问题。这些问题中最主要的是大多数通信方案的高路径损耗和直接瞄准线(LOS)要求。本研究提出了一种可重构智能表面(RIS)设计方案，以解决视线要求。由于太赫兹频率电磁波的特性，不能使用金属材料设计形成这些表面的单元胞。石墨烯材料根据其可控的表面阻抗特性，既提供了充分的反射条件，又可用于制造具有不同反射相位值和不同阻抗值的单元，从而制造出RIS结构。本研究在设计的RIS单元上获得了一定的反射相位范围，并在CST Microwave Studio 2019程序中设计并模拟了利用该单元将入射平面波定向到不同角度的RIS结构。

Currently, with the development of the communication systems, the demand for high speeds and spectrum is increasing. In order to satisfy this demand, Full-Duplex Communication Systems are being studied. Since the communication is done at the same time and frequency in Full-Duplex Communication systems, it doubles the spectrum efficiency. However, since the communication is done at the same time and frequency, the strong transmit signal leakage the receiver path which is called self interference. This self interference must be cancelled so that communication can continue. According to the study results, approximately 60 dB self interference cancellation achieved at 10 MHz bandwidth and 2.5 GHz. Error Vector Magnitude analysis was carried out in order to examine the effect of this self Interference cancellation on communication systems. According to this analysis, -55 dBm receiving sensitivity performance was measured while transmitting 0 dBm.

Photoacoustic tomography imaging is a new medical imaging technique based on the principle of converting the acoustic wave emitted from the tissue heated by laser beams to an image by measuring it with an ultrasound probe. Image quality in photoacoustic tomography depends on the imaging algorithm, as well as the establishment of the data generation and collection system in accordance with its intended use. In this study, studies were carried out to establish the photoacoustic tomography system, which will be established for the purpose of imaging skin cancer, in a way that will give the most optimum image result depending on the parameters that make up the experimental setup. For this purpose, a trigger system has been set up for the laser and acoustic data acquisition unit to work synchronously, the structure of the mechanism has been examined so that the laser beams can be dropped on the tissue with the least energy loss, and the angle between the laser beam and the receiver probe has been determined.
