How to Develop a Help System for a Communication App

This study aimed to develop a help system for a communication app, identify usability issues regarding that help system and develop redesigns to improve it. The focus was to maximize perceived usefulness and minimize perceived annoyance of the help system. During the study two design proposals were developed and two user tests, which used low-fidelity prototypes. were performed to evaluate the design proposals. The first design proposal was evaluated in the first user test, thereafter an iteration of that design was developed based on the usability issues found in the user test. This iteration of the design was the second design proposal which were evaluated in the second user tests. Both design proposals and data from both user tests were analysed to- gether which resulted in seven recommendation that aimed to maximize perceived usefulness and minimize perceived annoyance when developing a help system for a communication app. Due to a lack of generalizability these recommendations should however be used with caution since they are mainly applicable to the system evaluated in this study. They can however be used as an inspi- ration and a starting point for someone designing a help system for an other communication app.
Analysis of Leakage in Bolted-Flanged Joints Using Contact Finite Element Analvsis

The evolution of leakage is studied using detailed contact finite element analysis. The distribution of stress at the gasket is analyzed using a contact condition based on slide-line elements using ABAQUS, a commercial finite element code. Slide-line elements also take into account pressure penetration as contact that is lost between flange and gasket. Results are presented for a particular flange, a raised face flange sealed by a mild steel gasket. A comparison of the results from the gasket contact analysis and the contact conditions specified by the ASME Boiler and Pressure Vessel Code, Sections VIII, Division 1 shows that the conditions specified in the ASME Code predict leakage relatively accurately.

A Computational Binding Affinity Estimation Protocol with Maximum Utilization of Experimental Data : A Case Study for Adenosine Receptor

Estimating binding affinity between a target protein and the ligand is a crucial step in the drug discovery process. In computer aided drug design (CADD), the problem can be divided into two steps, finding the correct binding pose and estimating binding free energy. In this study, a new binding affinity estimation protocol, which uses molecular docking and binding affinity estimation with Molecular Dynamics (MD) simulation and maximizes the use of available experimental data, is suggested. Docking with a custom scoring function was used to find a better initial binding pose and Linear Interaction Energy (LIE) method with an optimized coefficient was used to estimate the binding affinity. The protocol has been validated with an external validation set and applied to five modafinil and its derivatives to set the order of binding affinity to Adenosine A2A receptors (ADORA2A, A2aR), which is a membrane protein, for a case study. This protocol could be time efficient and useful for computational drug discovery where limited experimental data is available.
Design of an array-based aid for the hearing impaired

The performance of our hearing system degrades with age, causing a reduction in our ability to understand speech. This thesis describes the design of a personal audio system, aimed at enhancing the audio signal from a TV, for hard of hearing listeners. Such system generates a zone of high acoustic pressure in a specific area of a room, whilst minimising the sound radiated to other zones. In order to obtain a very narrow sound radiation, superdirective techniques are used. Such techniques improve the performance of an array of small dimensions at mid and low frequencies, but they can require the use of a large amount of power and can be very sensitive to errors in the source transfer functions. A practical balance between performance and array effort is achieved in a design that uses phase-shift sources. Two arrays have been built. The first array uses 8 phase-shift sources and provides a high directionality in the free field. The second array uses 4 phase-shift sources vertically plus 8 horizontally and is more directional in a 3D sense, hence reducing the reverberant field excitation. The design of superdirective filters has been considered in both time and frequency domains. The effect of the reverberant field in the performance of superdirective radiators has also been investigated, by first examining how the radiation pattern is modified, and then by observing how the reverberant field affects the robustness of the control. The performance has been assessed by means of off-line simulations with point source Green functions and measured transfer responses, and by real time measurements in free-field and reverberant environments. The later chapters of the thesis consider the subjective assessment of arrays as an aid for speech intelligibility. The assessment has first been performed using an objective metric, in particular the speech transmission index (STI). The performance has also been assessed in a subjective study, in which 30 participants have judged the increase in intelligibility. A cochlear model has also been utilised to investigate equalisation methods that minimise masking and provide a better speech intelligibility, particularly for the hearing impaired. Although this has not been tested with behavioural experiments, STI simulations have predicted that it can lead to an intelligibility improvement.
Low Velocity Impact on Pre-Loaded Composite Structures

Low velocity impact is a serious hazard for laminated composite structures. It can result in considerable loss of mechanical performance and must be taken into account during the design process. Extensive knowledge of the composite damage processes and advanced numerical simulation tools can help nd optimal designs and reducing development costs. In addition to normal service loads such as bending moments, shear forces, torques, pressure loads, etc. airframe structures also have to withstand impact loads resulting from hailstones, runway debris or tool drops during maintenance work. These impacts are likely to happen while the airframe is stressed under normal service loads. The superposition of service loads and impact loads is likely to alter the impact response of a structure compared to an unloaded structure. In this work, the in uence of in-plane compressive loads on the low velocity impact response of carbon bre epoxy composites is studied. Low velocity impact experiments on T800s/M21 UD carbon bre epoxy laminates, under various compressive pre-strains, have been carried out with impact energies of up to 45J. The compressive pre-load applied to the structure was observed to signi cantly increase the impact damage and reduce the post-impact strength. To predict the damage resulting from impacts with and without pre-loads, a 2D damage model has been developed and implemented into the commercial nite element code ABAQUS/Explicit. The model is based on a combination of continuous damage mechanics and fracture mechanics with interactions between damage modes considered for both, damage initiation and damage propagation. Thereby damage degradation is following non-linear propagation laws. The model's material degradation is governed by the material's fracture toughnesses which are important material input parameters for the damage model. A detailed series of laboratory tests have been conducted to develop test set-ups for the measurement of translaminar fracture toughness values, which are used as input units for the damage model.
Financial Value of Analyst Recommendations: Talent or Risk Factor?

Financial analysts not only contribute to the informational efficiency of stock markets with their detailed reports, they also have the power to influence portfolio decisions of the larger financial investment industry through their recommendations. This study aims to explain the returns of portfolios formed based on analyst recommendations on Borsa Istanbul (BİST) stocks via known risk factors and to test the success of such recommendations in generating risk-adjusted alphas. In that regard, the returns of equal and value weighted portfolios based on analyst recommendations have been tested via CAPM, Fama-French and Carhart models. Furthermore, the financial value of analyst recommendations at times of economic turmoil is tested by taking recession periods into consideration. Although, positive recommendations from analysts seem to generate additional returns; when explained through well-known risk factors, the existence of an excess return with economic and statistical significance appears questionable. Our findings show that, analyst recommendations cannot be utilized to generate a meaningful alpha above and beyond the well-known risk factor premiums for BİST within respective period.
The Rule of Law for the Right to Inclusive Education in Indonesia

Indonesia is committed to guarantee the right to education for all citizens without exception. The commitment of Indonesia to Education for All (EFA) leads to the fulfillment of inclusive education policies. The people of Indonesia tend to understand inclusive education as education for people with disabilities. On the other hand, inclusive education has a broader meaning, which does not refer only to special education. Furthermore, it also covers education with special services. The essence of inclusive education is to remove barriers that limit all marginalized learners, to respect diversity and needs, to create patterns of education without discrimination, and ultimately to achieve quality education. People’s understanding leads to questions about inclusive education in legal context, as well as the rules of inclusive education in Indonesia. This paper contains a qualitative study with a historical-doctrinal approach. The study aims to explain the right to inclusive education listed in the rules and regulations in Indonesia and their problems. From the normative point of view, the rules on inclusive education are regulated in the Law Number 8 of 2016 on Persons with Disabilities and the Regulation of the Minister of National Education Number 70 of 2009. Furthermore, the rules of inclusive education can also be found in several other regulations implicitly. Most of the rules have stipulated provisions that include the right to education. Therefore, the Government appears to be progressively realizing the respect, protection, and fulfillment of the right to education, including inclusive education, for all people of Indonesia.
Teleoperation and robotics :: applications and technology

It is a privilege to be asked to introduce this important work. Such a book has long been needed. Industrial manipulators and robots have caught the attention of the general public and become very fashionable in the last few years. The casual reader of current newspapers and magazit: les or the viewer of television and films might easily conclude that the development of mechanical hands, arms and legs or other mobility devices has progressed rapidly in only the last few years. Most people are unaware of the gradual orderly succession of creative designs and painstaking refinements which have been produced over a greater number of years. That story is carefully described in this volume, together with diagrams and photographs which document in detail this elegant phase in the history of machine design. This volume together with Volume 3A constitute the most complete and comprehensive work on manipulators and teleoperators. Jean Vertut and Philippe Coiffet are well known not only as authors but also as engineers who have produced some of the finest devices in the world. Of course for the complete history of manipulators and teleoperators one must look back to the artisans who crafted the delightful clock works, mechanical puppets and toys before and during the Renaissance.

Hollow Mesoporous Silica Sphere (HMSS) as a Recyclable Nano-catalyst in an Efficient One-Pot Multicomponent Synthesis of 2-Amino-3-Cyano-4H-Pyran Derivatives

Mesoporous material has a significant role in medicine, health care, environmental monitoring, sensing the hazardous agents, and fighting against viruses and bacteria. Nano-silica sphere is an important member of the mesoporous family that noticeably flourished in biology, health care, and other industrial applications. Efficient one-pot multicomponent syntheses of 2-amino-3-cyano-4H-pyran derivatives were carried out over readily available and simply synthesized recyclable Hollow Mesoporous Silica Sphere (HMSS). Comparable yields were encountered with better efficiency, lower cost, and shorter reaction time. Hence, superior catalytic activity, flexibility, ease of recovery, tuneable hole size, and high surface to volume ratio were the major characteristics of the catalyst which distinguish this protocol from previously reported ones. The catalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR) techniques, and nitrogen absorption and desorption (BET) analyses. The results showed that the synthesizing of HMSS catalysts under a mild and green condition in which comparable yields were encountered with better efficiency, lower cost, and shorter reaction with other major economic advantages.
Developing a subdomain-oriented software product line

Reuse-oriented software methodologies have emerged to provide a set of rules or guides for development and evolution of software systems by reusing existing domain engineering artefacts such as requirements, architecture, components, test cases, etc. Domain engineering methods, such as software product lines engineering, aim at reducing development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. However, these methodologies are not based on specific domains, instead they cover a wide range of domains without considering particularities within them. Therefore, in this work we define a novel approach in which the creation of a software product line is guided by a subdomain analysis process, oriented to a particular case within the marine ecology domain. The methodology is then applied to a specific organization in order to create a product of the line.
Application of a 80 GHz all-optical clock in a 160 km transmission experiment

A novel 80 GHz all-optical clock recovery based on the self-pulsating "PhaseCOMB" (phase controlled optical mode beating) laser has been applied and tested for the first time in a system experiment, a transmission over 160 km. The jitter of the 80 Gb/s data signal generated on the transmitter side (238 fs) and of the 80 GHz clock recovered at the receiver side (282 fs) have been measured and compared. Both show an excellent low timing jitter of less then 300 fs, matching demands even for operation at higher data rates, e.g. 160 Gb/s. The good system performance of the novel 80 GHz optical clock based on the PhaseCOMB thus has been verified. We expect the PhaseCOMB will become a key component for high speed all-optical signal processing.

Making together : creative collaboration for everyone

This thesis explores how we can design learning environments to support broad participation in creative collaboration—that is, the process of working together on the construction of an artifact. I describe and analyze the design and implementation of Collab Camp, a learning environment that supports creative collaboration among members in the Scratch online community. The design of Collab Camp is based on four intersecting goals: encourage collaboration, support making, connect to interests, and cultivate community. I use a designed-based learning approach to iteratively design, implement, and evaluate this learning environment. I conclude by reWecting on the implementations and analyses to suggest ways in which we can support everyone in making together.

User-Centered Design and Evaluation of an Upper Limb Rehabilitation System with a Virtual Environment

Virtual environments (VEs) and haptic devices increase patients’ motivation. Furthermore, they observe their performance during rehabilitation. However, some of these technologies present disadvantages because they do not consider therapists’ needs and experience. This research presents the development and usability evaluation of an upper limb rehabilitation system based on a user-centered design approach for patients with moderate or mild stroke that can perform active rehabilitation. The system consists of a virtual environment with four virtual scenarios and a developed haptic device with vibrotactile feedback, and it can be visualized using a monitor or a Head-Mounted Display (HMD). Two evaluations were carried out; in the first one, five therapists evaluated the system’s usability using a monitor through the System Usability Scale, the user experience with the AttrakDiff questionnaire, and the functionality with customized items. As a result of these tests, improvements were made to the system. The second evaluation was carried out by ten volunteers who evaluated the usability, user experience, and performance with a monitor and HMD. A comparison of the therapist and volunteer scores has shown an increase in the usability evaluation (from 78 to >85), the hedonic score rose from 0.6 to 2.23, the pragmatic qualities from 1.25 to 2.20, and the attractiveness from 1.3 to 2.95. Additionally, the haptic device and the VE showed no relevant difference between their performance when using a monitor or HMD. The results show that the proposed system has the characteristics to be a helpful tool for therapists and upper limb rehabilitation.
A High-Efficiency Segmented Reconfigurable Cyclic Shifter for 5G QC-LDPC Decoder

A reconfigurable cyclic shifter is a key element of a QC-LDPC decoder, which is crucial for 5G communication systems. If a traditional reconfigurable cyclic shifter can only shift one input of variable size at a time, a traditional QC-LDPC decoder can only decode one codeword at a time as well. Part of the circuitry of the traditional QC-LDPC decoder inevitably stays in idle during the decoding process if the length (or the lifting parameter) of a codeword is not the maximum, resulting in low hardware efficiency. A segmented reconfigurable cyclic shifter is proposed in this paper, which can be divided into multiple segments of different sizes. Each segment can perform a cyclic shift of an input of different sizes and of different shift values independently. Furthermore, a methodology is proposed to upgrade any state-of-the-art QC-LDPC decoder to a segmented QC-LDPC decoder, by using the proposed segmented shifter. The upgraded segmented QC-LDPC decoder is able to parallelly decode multiple codewords (or inputs) of different lengths at a time. A test chip of the proposed segmented QC-LDPC decoder with the proposed segmented reconfigurable cyclic shifter has been fabricated in a 0.18- $\mu \text{m}$ CMOS technology to demonstrate the feature of parallelly decoding multiple codewords. The performance analysis shows that when the number of small codewords is increased from 0 to 100000 per second, the throughput of the traditional QC-LDPC decoder drops from 844.80 Mbps to 4.40 Mbps, while the QC-LDPC decoder with the proposed segmented shifter only slightly drops to 814.01 Mbps. By applying the segmented QC-LDPC decoder in 5G base stations, the base stations are enabled to support more low-traffic users.
