Examining the Interrelation and Perceptual Influence of Head-Related Transfer Functions Distance Metrics

Head-Related Transfer Functions (HRTFs) become necessary when using headphones to create virtual audio scenes. They approximate the interaction of the sound with the body of the listener. They can be also used in hearing aid fitting and psychology, where individually measured HRTFs are better suited than generic ones. For comparison of HRTF datasets, distance metrics, taking different types of errors into account, can be used. Five distance metrics were examined in the present work. The main objective of this thesis was to examine mutual information and interaction of these metrics and reduce them to a smaller set of measures suitable for a listening experiment. A further objective was to design and conduct a listening experiment paradigm to examine just noticeable differences (JND) as well as gain first insights into various perceptual attributes using respective distance metrics for prediction. The present mutual information and interactions between different objective distance metrics were analysed and evaluated using tools such as correlation analysis, principal component analysis and factor analysis. Three distance metrics (Inter-subject Spectral Difference: ISSD, Mean Squared Error: MSE and Mel-frequency Cepstral Distortion: MFCD) providing the most diverse information were selected for the listening test. To examine an audible threshold of these metrics, a 3AFC listening test paradigm was proposed. The test also focused on finding a relation of selected distance metrics and subjective perceivable attributes (coloration and localization). These attributes were inspected in different conditions, enabling observations in alignment with the right ear advantage presumption. Suggestions were given for further steps in the metric development, based on the present work.
Design of Love wave sensor devices for the operation in liquid environments

Love wave sensors are highly sensitive microacoustic devices, which are well suited for liquid sensing applications. The successful utilization of Love wave devices thereby requires proper shielding to avoid unwanted electric interaction of the liquid with the wave and the transducers. In this contribution we describe the effects of this electric interaction and the proper design of a shield to prevent it. Analysis methods illustrating the impact of the interaction and providing rules for the optimized design of the proposed shield are presented. Finally we show experimental results for devices that have been fabricated according to these design rules.

A Case Study on Tomorrow’s Smart Classroom: The Greek Paradigm

In this report we are going to provide a glimpse of the future of the Lower Secondary (Gymnasio) schools of Greece, thus the attempt of implementing broad use of ICT in the classroom and the issues and constrains that this attempt posses to the educational system, the teachers and the students altogether. More specifically after a number of analogous projects in the past, the Greek Ministry of Education, Lifelong Learning & Religious Affairs (Ministry), realized that the time for a broader use of ICT in the Greek educational system has came. According to various studies the appropriate level of education for this implementation was Gymnasio. So the decision was taken and the first step was to provide pupils and teachers with the adequate amount of notebooks, in a “1-1” model. The next steps would be to install in each Gymnasio the appropriate infrastructure (server & wireless network), training teachers, provide educational software and support. But above all was the necessity for a master plan that would evaluate all aspects and provide a blueprint for the entire implementation.

Human Pose Estimation Using Wireless Signals

: In this project, we use Deep Learning to teach wireless devices to sense people’s postures and movements even from other side of the wall or any other form of occlusions. While normal humans can't see through walls, this Deep Learning system is trained using images of humans in certain poses and corresponding reflected radio frequencies from their bodies to tell what someone is doing. The system counts on the fact that Wifi Signals are not stopped by solid walls but get reflected off a person’s body. By using this combination of visual data and Deep Learning to see through walls, we can enable better scene understanding and smarter environments to live safer and more productive lives. We have used the CSI tool based on Raspberry pi to extract and process Wifi signals.
Key Molecular Mechanisms in the Pathogenesis of Amyotrophic Lateral Sclerosis (ALS)

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder with a poor prognosis involving both upper motor neurons (UMN) and lower motor neurons (LMN). ALS is considered a multifactorial disease that involves multifactorial emergence of complex interrelation and mechanisms, therefore, therapeutics for ALS should be able to block or compensate for various aberrant pathological events. Growing evidence suggests that endoplasmic reticulum (ER) stress and the UPR pathway, autophagy and apoptosis may be implicated in the pathogenesis of ALS. This review focuses on the recent findings to elucidate potential molecular mechanisms for ALS. A comprehensive understanding of the pathogenesis of ALS may lead to the discovery of a breakthrough treatment strategy for this disease.
Learning Hierarchical Structure with LSTMs

Recurrent Neural Networks (RNNs) are successful at modeling languages because of their ability to recognize patterns over an undeﬁned input length using their internal memory. However, the data kept in their memory decays over time due to a problem called vanishing gradients. Long Short-Term Memory (LSTM) units mitigate this problem with forget gates which help reserve its memory for only important data. This model has thus become very popular in natural language processing (NLP), because they are able to model context. Compared to ealier models used in NLP, LSTMs excel at modeling a language modeling. However, some aspects of their success in the ﬁeld have surprised researchers. Their apparent ability to model syntax suggests that they use mechanisms of learning which we do not yet fully understand. Research has been done on LSTMs and language syntax, in an effort to potentially further the ﬁeld. Yet, an exhaustive account of how the inside an LSTM works and what needs improving has yet to be compiled. Here, we hope to use previous research and some ﬁnal experiments to provide a clear picture of how LSTMs model hierarchical syntax.
Building Sustainability Assessment

Although social, economic, and cultural indicators are of substantial importance to the concept of sustainable building, this concept is usually related to environmental characteristics. Any building level assessment method is complex and involves contradictory aspects. Moreover, emphasizing qualitative criteria only increases confusion. R&D and standardization are thus concentrated to transparency and usability of the environmental methods. Other directions of research aim at performance-based design and methods to take regional and cultural aspects into account. In this paper, the perspectives of the sustainability assessment of a whole building are presented, based on a state of the art, feasibility study on performance analysis and the development of an extended life-cycle assessment for buildings. Using various tools, and based on the case studies of building sustainability assessment, environmental indicators were often shown to be of lesser importance than the other, soft ones. The first steps in the development of a building sustainability assessment method for Portuguese residential buildings will be presented and discussed in the end.
From Platform to Knowledge Graph: Evolution of Laboratory Automation

High-fidelity computer-aided experimentation is becoming more accessible with the development of computing power and artificial intelligence tools. The advancement of experimental hardware also empowers researchers to reach a level of accuracy that was not possible in the past. Marching toward the next generation of self-driving laboratories, the orchestration of both resources lies at the focal point of autonomous discovery in chemical science. To achieve such a goal, algorithmically accessible data representations and standardized communication protocols are indispensable. In this perspective, we recategorize the recently introduced approach based on Materials Acceleration Platforms into five functional components and discuss recent case studies that focus on the data representation and exchange scheme between different components. Emerging technologies for interoperable data representation and multi-agent systems are also discussed with their recent applications in chemical automation. We hypothesize that knowledge graph technology, orchestrating semantic web technologies and multi-agent systems, will be the driving force to bring data to knowledge, evolving our way of automating the laboratory.
Compact 3-bit Frequency Reconfigurable Monopole Antenna Realized with a Switchable Three-Line Section

This work proposes a compact 3-bit frequency-reconfigurable monopole antenna covering a broad reconfigurable range by inserting a switchable three-line section (STLS). The design starts with a conventional quarter-wavelength monopole line antenna, which is then replaced by a novel structure, the STLS. The STLS is composed of three parallel-connected lines with different lengths. Accordingly, three RF p–i–n diodes are introduced in the STLS to achieve binary reconfiguration. After all parameters of the antenna have been optimized, it will eventually output 2N = 8 (N is the number of switches) independent working states with different equivalent lengths and a reconfigurable working frequency. The number of states in a binary reconfigurable antenna is optimally large in relation to the number of switches used, which means that it can be extremely convenient for digital control of switching all the states and capable of decreasing the number of RF p–i–n diodes we used, thereby minimizing the manufacturing cost and loss of diodes. A prototype antenna is fabricated and tested, and the measurement results agree well with the simulation results, validating the good features, such as a large reconfigurable switchable frequency range from 0.95 GHz to 2.45 GHz with considerable working bandwidth varying from 40 MHz to 540 MHz for each state, simple structure, and a compact size of 70 × 40 mm2, which can be appropriately used for a multi-radio wireless system and handheld devices. All the states have a similar monopole radiation pattern with a good maximum efficiency and an acceptable peak gain according to its compact size.
THE IMPACT OF FRINGE BENEFITS ON EMPLOYEES PERFORMANCE AND DEVELOPMENT IN NIGERIAN BANKING SECTOR

This study will examine the impact of fringe benefits on employees’ performance and development in Nigerian Banking Sector. Performance and development is a way of judging past and present productivity of an employee in an organization. Fringe benefits are non-monetary compensation which organisations use as a source of motivation to enhance performance of employees working in the organization. The research will look critically the relationship between fringe benefits and employees’ performance and development among Nigerian banks. This will cut across but not limited to annual leave, free health scheme, pension, maternity leave, staff loan and advances etc. The study will focus on Sterling Bank in Lagos state to enable me drive down real challenges. I believe my recommendation will always focus on encouraging management of all banks to compute allocated fringe benefits to their employees across the industry through Banks’ Employers Association and harmonised their various fringe benefits policies accordingly.
Succinct Erasure Coding Proof Systems

—Erasure coding is a key tool to reduce the space and communication overhead in fault-tolerant distributed computing. State-of-the-art distributed primitives, such as asynchronous ver-iﬁable information dispersal (AVID), reliable broadcast (RBC), multi-valued Byzantine agreement (MVBA), and atomic broadcast, all use erasure coding. This paper introduces an erasure coding proof (ECP) sys-tem, which allows the encoder to prove succinctly and non-interactively that an erasure-coded fragment is consistent with a constant-sized commitment to the original data block. Each fragment can be veriﬁed independently of the other fragments. Our proof system is based on polynomial commitments, with new batching techniques that may be of independent interest. ECP has a clean API and allows constructing fault-tolerant systems in a modular way. To illustrate the beneﬁts of our ECP system, we show how to build the ﬁrst AVID protocol with optimal message complexity, word complexity, and communication complexity.
A Full-Scale Simulation and Analysis of Formation Flight during In-Air-Capturing

In the past two decades, the renewed interest in sustainable space transportation has fueled the development of many innovative reusable launch technologies. One such concept called ‘In-Air-Capturing (IAC)’ involves winged rocket stages captured mid-air and towed back to the launch site using an aircraft. The approach patented by German Aerospace Center (DLR), shows potential for substantial mass and cost reduction by eliminating the need for additional propulsion during the descent. A critical aspect of IAC requires the two involved vehicles to be in a formation flight with similar velocities, altitudes and flight path angles separated by a safe distance. The preliminary requirement is to maintain the formation for a minimum of 60 s, despite any external disturbances. This paper presents the modelling and simulation of a full-scale reusable launch vehicle and a towing aircraft attempting the formation flight for IAC. First, a suitable aircraft configuration is selected based on the aerodynamic performance of the selected test rocket stage. Important subsystems are also identified and modelled comprehensively. Then, trajectory simulations are performed to identify the best approach and initial conditions for the formation. Sensitivity of the formation flight to several factors like the idle thrust, wake turbulence and wind gusts are also analysed. The simulation yielded that the minimum duration of formation flight could be maintained, despite the external disturbances. Lastly, potential improvements and future simulations are discussed.
Propagation in periodically loaded waveguides with higher symmetries

A generalization of Floquet's theorem is presented for periodically loaded closed waveguides possessing a certain class of higher symmetries which includes the screw and glide symmetries. These symmetries frequently appear in microwave structures such as filters, traveling-wave tubes, and traveling-wave antennas. The theorem states that the natural modes are eigenvectors of the symmetry operator characterizing the structure. An alternative derivation of the theorem using an equivalent network representation leads naturally to a simple method for constructing the qualitative dispersion (Brillouin) diagrams for structures with screw or glide symmetry.

Simulator Building for Agile Control Design of Shipboard Crane and its application to Operational Training

Abstract In this paper, an integrated computer simulator tool of rotary crane with ship behavior in consideration of ship sway and load sway is newly built to systemize the state analysis of a shipboard crane. The integrated simulator of shipboard crane was realized by cooperating a component of external force interface routine and fluid analysis software. A transfer control system is conducted by HSA (Hybrid Shape Approach) using STT (Straight Transfer Transformation) method and its effectiveness in suppressing the sway of both ship and load was confirmed by the simulation analysis. A shipboard crane operational training system which we call virtual coach teaching system, is also presented, in order to shorten the training period of amateur operators. The controlled inputs generated from HSA controller which are utilized as the ideal commands are then converted to drive a newly built teaching interface. Subjects are physically coached through the ideal motion of joystick by placing their hand on the teaching interface, thus giving them a kinesthetic understanding on how to transfer a load without exciting the sway of both the ship and load. Performance of subjects was measured in terms of transfer time by conducting an experiment using a newly built virtual driving simulator. Findings from this study indicate that virtual coach teaching is effective in training.
