Clock synchronisation for UWB and DECT communication networks

Synchronisation deals with the distribution of time and/or frequency across a network of nodes dispersed in an area, in order to align their clocks with respect to time and/or frequency. It remains an important requirement in telecommunication networks, especially in Time Division Duplexing (TDD) systems such as Ultra Wideband (UWB) and Digital Enhanced Cordless Telecommunications (DECT) systems. This thesis explores three different research areas related to clock synchronisation in communication networks; namely algorithm development and implementation, managing Packet Delay Variation (PDV), and coping with the failure of a master node. The first area proposes a higher-layer synchronisation algorithm in order to meet the specific requirements of a UWB network that is based on the European Computer Manufacturers Association (ECMA) standard. At up to 480 Mbps data rate, UWB is an attractive technology for multimedia streaming. Higher-layer synchronisation is needed in order to facilitate synchronised playback at the receivers and prevent distortion, but no algorithm is defined in the ECMA-368 standard. In this research area, a higher-layer synchronisation algorithm is developed for an ECMA-368 UWB network. Network simulations and FPGA implementation are used to show that the new algorithm satisfies the requirements of the network. The next research area looks at how PDV can be managed when Precision Time Protocol (PTP) is implemented in an existing Ethernet network. Existing literature indicates that the performance of a PDV filtering algorithm usually depends on the delay profile of the network in which it is applied. In this research area, a new samplemode PDV filter is proposed which is independent of the shape of the delay profile. Numerical simulations show that the sample-mode filtering algorithm is able to match or out-perform the existing sample minimum, mean, and maximum filters, at different levels of network load. Finally, the thesis considers the problem of dealing with master failures in a PTP network for a DECT audio application. It describes the existing master redundancy techniques and shows why they are unsuitable for the specific application. Then a new alternate master cluster technique is proposed along with an alternative BMCA to suit the application under consideration. Network simulations are used to show how this technique leads to a reduction in the total time to recover from a master failure.

Project portfolio evaluation and selection using mathematical programming and optimization methods

Caballero, Hugo. Ph.D., Purdue University, December 2014. Project Portfolio Evaluation and Selection Using Mathematical Programming and Optimization Methods. Major Professor: Edie K. Schmidt. Project portfolio selection is an essential process for portfolio management and plays an important role in accomplishing organizational goals. This research explores the feasibility of developing a project portfolio selection tool by using mathematical programming and optimization models, specifically 0-1 integer programming (one objective portfolio) and goal programming (multiple objectives portfolio). These methods select the set of projects which deliver the maximum benefit (e.g., net present value, profit, etc.) represented for objective functions subjected to a series of constraints (e.g., technical requirements and/or resources availability) considering the scheduling of selected projects in a planning horizon, interdependence relationship among projects (e.g., complementary projects and mutually exclusive projects) and especial cases like mandatory and ongoing projects. Based on the proposed model, a Decision Support System (DSS) will be developed and tested for accuracy, flexibility and ease of use. This computational tool will be designed for decision makers and users that are not familiar with mathematical programming models.

The Architecture HuFaNCO - Modeling Imperfect Human Information Processing with Special Reference to Network Centric Operations

This paper presents new general agent architecture (HuFaNCO) for simulating a human decision maker as a single node embedded in Network Centric Operations (NCO) scenarios. The architecture is structured modularly and integrates psychologically funded modeling concepts for selected aspects of the human information processing system such as information intake and filtering based upon attention dynamics, situational awareness and problem solving strategies such as evaluation of decision trees. The modeling approach takes into account the influence of stress in terms of arousal, exhaustion and time pressure on the quality of results generated by the modeled cognitive functions. First experiments with a simulation model based on the architecture HuFaNCO demonstrated the capabilities to reproduce human errors concerning situational awareness and decision making in a realistic fashion.
How does the human brain react when confronted by a talking computer? Answers from psychological research and its design implications help define the limits of what computers should say and how they might say it.

Similarly, the human head and brain are uniquelyevolved to produce speech [4, 11]. Compared toother primates, humans have remarkably well-devel-oped and controllable muscles around the lips andcheeks. Indeed, more of the motor cortex (particu-larly Broca’s area) is devoted to vocalization than toany other function, in sharp contrast to every otheranimal, including primates. Only

The phase correlation algorithm for stabilization of capillary blood flow video frames

The capillary blood flow parameters recovery is one of the videocapillaroscopy objectives. Capillaries position can vary at recorded video sequences due to the registration features of capillary blood flow. Stabilization algorithm of capillary blood flow video frames based on the advanced phase correlation is proposed and investigated. This algorithm is compared to the advanced version of known algorithms of video frames stabilization based on full-frame superposition and key points detection. Programs based on discussed algorithms are compared by processing of the experimentally recorded video sequences of human capillaries and by processing of computer-simulated video frames sequences with the specified offset. The full-frame superposition algorithm provides high quality of stabilization, however, the program based on this algorithm requires significant computational resources. Software implementation of the key points detection algorithm is characterized by good performance, but provides low quality of stabilization for capillary blood flow video sequences. Algorithm based on phase correlation method provides high quality of stabilization and program realization of this algorithm requires minimal computational resources. It is shown that the phase correlation algorithm is the most useful for stabilization of video sequences for capillaries blood flow. Obtained results can be used in software for biomedical diagnostics.

Energy Consumption in Location Sharing Protocols for Android Applications

This thesis studies the Message Queue Telemetry Transport protocol (MQTT) as an application layer protocol in geographical location sharing applications using third generation cellular communication (3G). The MQTT protocol is compared in terms of energy efficiency and amount of data generated with the Hypertext Transfer Protocol (HTTP), which is currently used in typical location sharing applications.In order to compare the communication energy efficiency of both protocols a location sharing application prototype was developed for the Android platform. The application allows the use of HTTP and MQTT and was used to perform a number of experiments.The evaluation experiments show that MQTT is a good candidate as a protocol for location sharing. At comparable bandwidth and energy expenses MQTT offers better quality of user experience, since the subscribers are notified at once when the location of clients of interest has changed. The MQTT protocol is more energy-efficient than the HTTP protocol when the number of other uses with whom the client shares location is low and the location updates are frequent. The experiments also indicate that MQTT protocol is more energy-efficient than HTTP protocol in idle state, when there are no location information updates due to inactivity of all the clients, for example, if they are stationary. This is because MQTT client does not spend energy to poll the server for information updates.
Image segmentation using a generalized fast level set method

Image segmentation is one of the most important and fundamental tasks in image processing. In this paper we address the drawbacks of the previous level set methods for segmentation problems and propose a Generalized Fast Level Set Method to cope with the limitations. We formulate a new level set function, study its stability, introduce a relationship matrix, a modified Chan-Vese model and a novel filtering criterion to construct a novel and effective segmentation technique. The experimental results show that this technique can be used in segmenting individual objects or individual parts of an object in images, which is useful in reducing the heavy image noises. These results also demonstrate that the proposed method is more effective and efficient than the classical Level Set Methods and the original Fast Level Set Method.
Matthew P. Canepa. The Two Eyes of the Earth. Art and Ritual of Kingship between Rome and Sasanian Iran

Si l’etude des relations romano-sassanides a connu un important renouveau sur les trente dernieres annees, c’est essentiellement les sources documentaires (litteraires et epigraphiques) qui ont ete mises en avant pour une analyse approfondie. Les domaines de la numismatique, de la sigillographie et de la papyrologie ont certes ete tout aussi innovants sinon plus encore, mais elles touchent en tres grande partie a des questions internes a l’empire sassanide et sont moins concernes par des refl.
Intellectual Development and Learning at Early Age. A Theoretical Perspective

The intellectual development at early agesoccupies large spaces in the specialized literature. However, there are many issues that have remained unknown or insufficiently explained. In this sense, the present paper aims to illustrate the relation between the characteristics of the child's intellectual development and the learning process at early ages. It is about a theoretical approach by which we have tried to argue the necessity of knowing these particularities of the child's development, as well as the imperative necessity to reconsider the formal learning process. The analysis of the experimental research in the field indicates the existence of clear correlations between the changes that take place at this stage in the architecture of the intellectual development and variables such as: the previous experiences the child had to face with, the quality of the socio-family environment, the parents’ educational level, the way the child plays, the degree of leadership of the game-based activities.Moreover, by its content, the paper aims to draw attention upon the importance and complexity of this issue and can be considered a good starting point for the experimental investigation of the changes taking place at the age of intellectual development.

Below bandgap photoluminescence of an AlN crystal: Co-existence of two different charging states of a defect center

The below bandgap optical transitions of an aluminum nitride (AlN) crystal grown on a tungsten (W) substrate by physical vapor transport (PVT) are investigated by below-bandgap-excited photoluminescence (PL) spectroscopy and first-principles calculations. Oxygen (O) is the only impurity in the AlN-on-W crystal grown by PVT. By analyzing the excitation-power-, excitation-photon-energy-, and temperature-dependence of the PL spectra, the emission peaks of defect complexes involving aluminum vacancy (VAl) and substitutional oxygen (ON) with different spatial and atomic configurations, i.e., VAl–ON and VAl–2ON with ON featuring axial or basal configurations, are identified. It is revealed that two different charging states coexist in thermal equilibrium for each configuration of VAl–ON complexes. The optical transitions between the conduction band and (VAl–ON)2− and/or (VAl–2ON)1− contribute the UV emissions and those between the valence band and (VAl–ON)1− or (VAl–2ON)0 contribute the red emissions.

Custom Datapaths for DSP ASICs Methodology and Implementation

This thesis regards datapath design and analysis at several abstraction levels. Five papers are presented that focus on datapath design for mobile communication systems and design methodologies for such datapaths. Paper I discusses different aspects of Turbo channel decoder design for high speed and low power applications. It is shown that critical path delay is significantly reduced by simple rescheduling operations. A new topology is presented for UMTS interleavers that achieves significantly higher throughput with lower power consumption and smaller area. In paper II, a datapath design methodology based on a fast handshaking protocol is presented. The methodology is implemented with a small set of flexible and lean modules that compared to standard handshaking protocols have both smaller delay and lower implementation cost for pipelined datapath designs. In paper III software domain abstraction paradigms are applied to the design of a hardware datapath library in C++. Several methodologies in the software domain are shown to aid the design process. Two of the more important are design for interfaces and design with design patterns. It is shown that reliability and usability are improved by the application of software paradigms. Papers IV and V deal with the design of broadband interpolating and decimating channel filters for low power applications. All filters are of the lattice wave digital filter type, which is suitable for parallelization and has good filtering properties. Several architectural modifications are described to increase the parallelism and achieve lower clock frequency and supply voltage.
Bayesian System Identification of Nonlinear Systems: Informative Training Data through Experimental Design

This paper addresses the situation where one is performing Bayesian system identification on a nonlinear dynamical system using a set of experimentally - obtained training data. To be more specifi c, an investigation is performed to find the optimum form of excitation that should be used during generation of the training data. To that end, the Shannon entr opy is used as an information measure such that, through analysing the information content of t he posterior parameter distribution, the `informativeness' of different sets of training data can be assessed. In the current work the form of excitation is parameterised thus allowing the choosing of an appropriate excitation to be phrased as an optimisat ion problem (where one is aiming to maximise the information content of the training data).
USER REQUIREMENTS OF A CROWDSOURCING PLATFORM FOR RESEARCHERS: FINDINGS FROM A SERIES OF FOCUS GROUPS

While the concept of crowdsourcing has generated significant interest in the information systems (IS) research community, the application of crowdsourcing for research itself remains limited. This limitation in the adoption of crowdsourcing by researchers is partly explained by the lack of a crowdsourcing platform that is suitable for their needs. This paper presents the findings of a focus group study involving 28 researchers which aimed to reveal how such a platform should be designed. Based on the study, we are able to articulate a set of functional and non-functional requirements of a crowdsourcing platform for researchers. The findings will support researchers in design science and computer science to develop an appropriate crowdsourcing platform for researchers.
Developing mathematics teaching through inquiry – a response to Skovsmose and Säljö

This paper constitutes a response to the article by Skovsmose and Saljo (2008) in Nomad. We focus on the concept of inquiry as used in the KUL projects at the University of Agder, Norway, 2004–2007, from which Skovsmose and Saljo offered an evaluation and critique. We begin by clarifying certain aspects of the two KUL projects, Learning communities in mathematics and ICT in mathematics learning. In doing so, we agree substantially with several of the points made by Skovsmose and Saljo. We go on to address their two main criticisms: that research in the KUL projects shows little documentation of inquiry processes or patterns of classroom interaction between teachers and students, or among students; and that the KUL projects demonstrate few attempts to use real life environments as a basis for establishing inquiry processes. Finally we come back to significant issues related to inquiry and the main focus of the two projects, further research questions and relations between the micro and the macro in mathematics education research.
