Abstract:

This bachelor thesis has been carried out at the company Didamus which is located in Mjärdevi, Linköping. The company is currently developing a dive-console which aims to take the scuba diving experience to a whole new level and also to make scuba diving more secure. An assembly of scuba divers that can communicate with each other during a dive session might be the difference between life and death. Many seas around the world have muddy water which means poor visibility. In each situation a computer providing a scuba diver with information about others connected to the network, hazardous accidents can possibly be avoided. The network itself consist of 10 nodes that need a network protocol which provides stability and reliability for every participant. The nodes themselves have a distributed responsibility to make the network reliable. The type of network implemented was a regular Time Division Multiple Access (TDMA) network where different nodes were given permission to access the medium in different instances of time. A global reference of time is always needed in a TDMA network to make it function properly. In a typical TDMA network a GPS-service gives each and every node information about the global time. Unfortunately, GPS-services do not work well in water so a Master-Slave method was used instead. The master provides the rest of the nodes in the network with a global time reference. After a successful reception of a global time reference, the slave will be granted access to the network. The communication between the nodes is based on ultrasonic waves propagating in the water. The velocity of ultrasonic waves in water is only 1500 meters per second, explained in Discovery of Sound in the Sea by University of Rhode Island, which is a relatively slow signal speed. With the slow velocity taken into account an efficient TDMA protocol was developed, to perform communication under water.

Abstract:

Network programming is one of the most important applications in Wireless Sensor Networks as It provides an efficient way to update program Images running on sensor nodes without physical access to them. Securing these updates, however, remains a challenging and important issue, given the open deployment environment of sensor nodes. Though several security schemes have been proposed to impose the authenticity and Integrity protection on network programming applications, they are either energy Inefficient as they tend to use digital signature or lacks the data confidentiality. In addition, due to the absence of secure memory management in the current sensor hardware, the attacker could inject malicious code into the program flash by exploiting buffer overflow In the memory despite the secure code dissemination. The contribution of this thesis Is to provide two software-based security protocols and one hardware-based remote attestation protocol for network programming application. Our first protocol deploys multiple one-way key chains for a multi-hop sensor network. The scheme Is shown to be lower In computational, power consumption and communication costs yet still able to secure multi??hop propagation of program images. Our second protocol utilizes an Iterative hash structure to the data packets in network programming application, ensuring the data confidentiality and authenticity. In addition, we Integrated confidentiality and DoS-attack-resistance in a multi??hop code dissemination protocol. Our final solution is a hardware-based remote attestation protocol for verification of running codes on sensor nodes. An additional piece of tamper-proof hardware, Trusted Platform Module (TPM), is imposed into the sensor nodes. It secures the sensitive information (e.g., the session key) from attackers and monitors any platform environment changes with the Internal registers. With these features of TPM, the code Injection attack could be detected and removed when the contaminated nodes are challenged in our remote attestation protocol. We implement the first two software-based protocols with Deluge as the reference network programming protocol in TinyOS, evaluate them with the extensive simulation using TOSSIM and validate the simulation results with experiments using Tmote. We implement the remote attestation protocol on Fleck, a sensor platform developed by CSIRO that Integrates an Atmel TPM chip.

Abstract:

Systems biology comprises the global, integrated analysis of large-scale data encoding different levels of biological information with the aim to obtain global insight into the cellular networks. Several studies have unveiled the modular and hierarchical organization inherent in these networks. In this dissertation, we propose and develop innovative systems approaches to integrate multi-source biological data in a modular manner for network inference and biomarker discovery in complex diseases such as breast cancer. The first part of the dissertation is focused on gene module identification in gene expression data. As the most popular way to identify gene modules, many cluster algorithms have been applied to the gene expression data analysis. For the purpose of evaluating clustering algorithms from a biological point of view, we propose a figure of merit based on Kullback-Leibler divergence between cluster membership and known gene ontology attributes. Several benchmark expression-based gene clustering algorithms are compared using the proposed method with different parameter settings. Applications to diverse public time course gene expression data demonstrated that fuzzy c-means clustering is superior to other clustering methods with regard to the enrichment of clusters for biological functions. These results contribute to the evaluation of clustering outcomes and the estimations of optimal clustering partitions. The second part of the dissertation presents a hybrid computational intelligence method to infer gene regulatory modules. We explore the combined advantages of the nonlinear and dynamic properties of neural networks, and the global search capabilities of the hybrid genetic algorithm and particle swarm optimization method to infer network interactions at modular level. The proposed computational framework is tested in two biological processes: yeast cell cycle, and human Hela cancer cell cycle. The identified gene regulatory modules were evaluated using several validation strategies: 1) gene set enrichment analysis to evaluate the gene modules derived from clustering results; (2) binding site enrichment analysis to determine enrichment of the gene modules for the cognate binding sites of their predicted transcription factors; (3) comparison with previously reported results in the literatures to confirm the inferred regulations. The proposed framework could be beneficial to biologists for predicting the components of gene regulatory modules in which any candidate gene is involved. Such predictions can then be used to design a more streamlined experimental approach for biological validation. Understanding the dynamics of these gene regulatory modules will shed light on the related regulatory processes. Driven by the fact that complex diseases such as cancer are “diseases of pathways”, we extended the module concept to biomarker discovery in cancer research. In the third part of the dissertation, we explore the combined advantages of molecular interaction network and gene expression profiles to identify biomarkers in cancer research. The reliability of conventional gene biomarkers has been challenged because of the biological heterogeneity and noise within and across patients. In this dissertation, we present a module-based biomarker discovery approach that integrates interaction network topology and high-throughput gene expression data to identify markers not as individual genes but as modules. To select reliable biomarker sets across different studies, a hybrid method combining group feature selection with ensemble feature selection is proposed. First, a group feature selection method is used to extract the modules (subnetworks) with discriminative power between disease groups. Then, an ensemble feature selection method is used to select the optimal biomarker sets, in which a double-validation strategy is applied. The ensemble method allows combining features selected from multiple classifications with various data subsampling to increase the reliability and classification accuracy of the final selected biomarker set. The results from four breast cancer studies demonstrated the superiority of the module biomarkers identified by the proposed approach: they can achieve higher accuracies, and are more reliable in datasets with same clinical design. Based on the experimental results above, we believe that the proposed systems approaches provide meaningful solutions to discover the cellular regulatory processes and improve the understanding about disease mechanisms. These computational approaches are primarily developed for analysis of high-throughput genomic data. Nevertheless, the proposed methods can also be extended to analyze high-throughput data in proteomics and metablomics areas.

Abstract:

Energy efficiency is a driving factor in modern electronic design particularly in power conversion where conversion losses directly set the upper limit of system efficiency. A wide variety of commercially available DC-DC conversion elements have inefficiencies in the 90-97% range. The efficiency range of most common commercial-off-the-shelf (COTS) power supplies is 75-85%, highlighting the fact that COTS power supplies have not kept pace with efficiency improvements of modern conversion elements. Unmanned ground vehicles (UGVs) is an application where efficiency can be crucial in extending tight power budgets. In autonomous ground vehicles, geographic diversity with regard to sensor location is inherent because sensor orientation and placement are crucial to performance. Sensor power, therefore, is also distributed by nature of the devices being supplied. This thesis presents the design and evaluation of a smart power module used to implement a distributed power network in an autonomous ground vehicle. The module conversion element demonstrated an average efficiency of 96.7% for loads from 1-4A. Current monitoring and an adjustable output current limit were provided through a second circuit board within the same module enclosure. The module processing element sends periodic updates and receives commands over a CAN bus. The smart power modules successfully supply critical sensing and communication components in an operational autonomous ground vehicle.

An orbiting sensor module, designed by The Johns Hopkins University Applied Physics Laboratory (JHU/APL), performed a number of significant Strategic Defense Initiative (SDI) Delta 181 program experiments. These experiments required on-orbit command and monitor operations involving a worldwide network of ground facilities. A major component was the sensor module command center (SMCC), which was designed and integrated by JHU/APL. The SMCC, located at Cape Canaveral Air Force Station (CCAFS), connected to a network of Eastern Test Range, Air Force Satellite Control Network (AFSCN), Kennedy Space Center, and Western Test Range assets. The complex nature of the mission presented numerous challenges to the design, integration, and operation of the SMCC. This paper presents a functional overview of SMCC design as well as unique aspects of supporting ground network telemetry and command operation.

Abstract:

La classificazione automatizzata di documenti digitalizzati in categorie predefinite ha sollevato un grande interesse fin dagli anni 2000. Questo è dovuto al sensibile aumento di documenti in formato digitale ed alla crescente necessità di dar loro un’organizzazione gerarchica. Inoltre, principalmente a causa della grande mole di documenti da categorizzare, negli ultimi anni si richiede che tale compito venga gestito in modo automatizzato. In ambito aziendale, queste problematiche vengono spesso affrontate mediante l’utilizzo di soluzioni “black box” proprietarie. Tali soluzioni si rivelano poco performanti poiché non sufficientemente personalizzabili da essere applicate a domini specifici (general purpose). In questo lavoro, ci occuperemo del problema della categorizzazione di documenti digitalizzati, nel settore della gestione della modulistica contabile. Il Machine Learning è stato largamente utilizzato nel processing di immagini degli ultimi anni grazie alla portabilità dei suoi risultati e capacità di produrre modelli affidabili anche a partire da una scarsa connoscenza del dominio di riferimento. Questa tesi inizia con lo stato dell’arte riguardo ai classificatori di categorie di documenti digitalizzati. In seguito viene descritto l’uso di tecniche di Machine Learning (DNNs) per Document Image Classification, con approfondimenti sull’architettura, il dataset e il modello utilizzato. Infine viene presentato McGiver, uno strumento per classificare documenti in categorie a partire dalla loro versione digitale. Viene quindi descritta ogni fase di implementazione e produzione dei risultati di validazione: preprocessing del dataset, addestramento e validazione. Infine, nell’ultimo capitolo vengono presentate, argomentando le stesse, alcune considerazioni sui risultati ottenuti e una discussione sui lavori futuri.

Abstract:

Aircraft, wind turbines, or space stations are expected to remain in service well beyond their designed performance lifetime. Consequently, maintenance is an important issue for aircraft or aerospace structures. This is accomplished through inspecting for damage at scheduled times and replacing damaged parts before failure. Ground inspections of aircraft, even using simple nondestructive testing techniques, generally require the aircraft be pulled from operation so that its components can be inspected for damage. Structural components are replaced if sufficient damage is found. Research is underway to develop a structural health monitoring (SHM) system as a means to improve the current maintenance routine. This system would consist of an array of sensors and associated analysis codes which would scan for damage in-flight and perform real-time damage analysis of an aircraft’s structure. If damage is recognized long before failure occurs, then a damage tolerance and prognostic assessment could be implemented, allowing for a determination of the remaining life of components. The current method of inspecting aircraft, consisting of ground inspections for damage after a set number of flight hours, works well from an aircraft safety point of view. However, an in-flight SHM system would allow for better use of components, as specific lifetimes could be determined; and, could be less costly, since an SHM system could be embedded into the aircraft structure, thereby reducing or eliminating the need to tear down the aircraft to scan for damage during the ground inspection and would ultimately lead to fewer required ground inspections. General theory for material mechanics, fracture mechanics, waveform theory, and artificial neural networks are presented in this paper. Among these, a simple triangulation method is developed to locate a crack tip position and a procedure of combining the theory of fracture mechanics with waveform theories is introduced. These components were used collectively in a series of experiments to investigate the possibility of using them in a future SHM system. Flat aluminum panels, similar in thickness to those found in many aerospace structures, were subjected to increasing static loading during laboratory tests. As the load increased, a designed crack in the panel increased in size, releasing strain waves into the material. These waves were then detected by acoustic emission sensors, and artificial neural networks were implemented to analyze the received strain waves. From a feed-forward neural network, the crack length was approximated. Next, similar aluminum panels were placed in a simply supported beam configuration with ultrasonic actuators attached at various positions. These actuators created multiple point source locations, which was received by multiple acoustic emission sensors. The location of the source was calculated by both triangulation method and an vi artificial neural network. A theory of plastic zone interference with strain waves released from crack tip extension was introduced and shown as a possibility during the analysis of a final experiment. Sensors placed behind the crack front were observed to detect waves with smaller amplitudes than the sensors placed in locations in front of the crack during crack extension due to increasing, pseudo-static applied load. The effect of the acoustic emission sensor placement relative to crack tip growth detections was determined to be possibly integrated with an artificial neural network in future research. Experiments were conducted to determine the crack length and location, using artificial neural network analyses of acoustic emission signals. Artificial neural networks were developed which were trained with an existing dataset of crack properties. These neural networks were applied to new situations that were not part of the training dataset. The approximated crack growth of the artificial neural networks was around 10% shorter than the actual measured crack growth length for an extension of around 0.8 in. Finally, some SHM analysis systems were proposed, based on the conclusions made in the experiments. The artificial neural networks performed well at approximating both the crack extension and location, using acoustic emission detections. These artificial neural networks in combination with an acoustic emission system are reasonable candidate for the initial stages of a feasible structural health monitoring system to determine the location and severity of structural damage within an aerospace structure.

Abstract:

Location-based service (LBS) is a geographical location-related service that provides highly personalized services for users. It is a platform for network operators to provide new and innovative ways of increasing profits from new services. With the rapidly growing trend toward LBS, there is a need for standard LBS protocols. This thesis started with introducing the Internet Engineering Task Force GEOPRIV working group, which endeavors to provide standard LBS protocols capable of transferring geographic location information for diverse location-aware applications. Through careful observation, it was found that Session Initiation Protocol (SIP) is well suited to the GEOPRIV requirements. The aim of this research was therefore to explore the possibility of the integration of LBS and the SIP protocol and, to some extent fulfill the GEOPRIV requirements.

Abstract:

This thesis presents an analysis of the impact of node mobility on the quality of service for voice over Internet Protocol in wireless mesh networks. Voice traffic was simulated on such a mesh
network to analyze the following performance metrics: delay, jitter, packet loss and throughput. Wireless mesh networks present interesting characteristics such as multi-hop routing, node mobility, and variable coverage that can impact on quality of service. A reasonable deployment scenario for a small organizational network, for either urban or rural deployment, is considered with three wireless mesh network scenarios, each with 26 mesh nodes. In the first scenario, all mesh nodes are stationary. In the second scenario, 10 nodes are mobile and 16 nodes are stationary.
Finally, in the third scenario, all mesh nodes are mobile. The mesh nodes are simulated to move at a walking speed of 1.3m per second. The results show that node mobility can increase packet
loss, delay, and jitter. However, the results also show that wireless mesh networks can provide acceptable quality of service, providing that there is little or no background traffic generated by other
applications. In particular, the results demonstrate that jitter across all scenarios remains within humanacceptable tolerances. It is therefore recommended that voice over Internet Protocol implementations on wireless mesh networks with background traffic be supported by quality of service standards
otherwise they can lead to service delivery failures. On the other hand, voice-only
esh networks, even with mobile nodes, offer an attractive alternative voice over Internet Protocol platform.

Abstract:

The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate.

The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled. All measurements on the radio front-end and the test components are made using a network analyser, in order to measure the S-parameters.

This diploma work has resulted in a functional design and prototype, which has proved that designing systems for 5 GHz on a laminate substrate is possible but by no means trivial.

Abstract:

In the past several decades, Next Generation Sequencing (NGS) methods have produced large amounts of genomic data at the exponentially increasing rate. It has also enabled tremendous advancements in the quest to understand the molecular mechanisms underlying human complex traits. Along with the development of the NGS technology, many genetic variation and genotype–phenotype databases and functional annotation tools have been developed to assist scientists to better understand the intricacy of the data. Together, the above findings bring us one step closer towards mechanistic understanding of the complex phenotypes. However, it has rarely been possible to translate such a massive amount of information on mutations and their associations with phenotypes into biological or therapeutic insights, and the mechanisms underlying genotype-phenotype relationships remain partially explained. Meanwhile, increasing evidence shows that biological networks are essential, albeit not sufficient, for the better understanding of these mechanisms. Among them, protein- protein interaction (PPI) network studies have attracted perhaps most attention. Our overarching goal of this dissertation is to (i) perform a systematic study to investigate the role of pathogenic human genetic variant in the interactome; (ii) examine how common population-specific SNVs affect PPI network and how they contribute to population phenotypic variance and disease susceptibility; and (iii) develop a novel framework to incorporate the functional effect of mutations for disease module detection. In this dissertation, we first present a systematic multi-level characterization of human mutations associated with genetic disorders by determining their individual and combined interaction-rewiring effects on the human interactome. Our in-silico analysis highlights the intrinsic differences and important similarities between the pathogenic single nucleotide variants (SNVs) and frameshift mutations. Functional profiling of SNVs indicates widespread disruption of the protein-protein interactions and synergistic effects of SNVs. The coverage of our approach is several times greater than the recently published experimental study and has the minimal overlap with it, while the distributions of determined edgotypes between the two sets of profiled mutations are remarkably similar. Case studies reveal the central role of interaction- disrupting mutations in type 2 diabetes mellitus and suggest the importance of studying mutations that abnormally strengthen the protein interactions in cancer. Second, aided with our SNP-IN tool, we performed a systematic edgetic profiling of population specific non-synonymous SNVs and interrogate their role in the human interactome. Our results demonstrated that a considerable amount of normal nsSNVs can cause disruptive impact to the interactome. We also showed that genes enriched with disruptive mutations associated with diverse functions and have implications in various diseases. Further analysis indicates that distinct gene edgetic profiles among major populations can help explain the population phenotypic variance. Finally, network analysis reveals phenotype-associated modules are enriched with disruptive mutations and the difference of the accumulated damage in such modules may suggest population-specific disease susceptibility. Lastly, we propose and develop a computational framework, Discovering most IMpacted SUbnetworks in interactoMe (DIMSUM), which enables the integration of genome-wide association studies (GWAS) and functional effects of mutations into the protein–protein interaction (PPI) network to improve disease module detection. Specifically, our approach incorporates and propagates the functional impact of non- synonymous single nucleotide polymorphisms (nsSNPs) on PPIs to implicate the genes that are most likely influenced by the disruptive mutations, and to identify the module with the greatest functional impact. Comparison against state-of-the-art seed-based module detection methods shows that our approach could yield modules that are biologically more relevant and have stronger association with the studied disease. With the advancement of next-generation sequencing technology that drives precision medicine, there is an increasing demand in understanding the changes in molecular mechanisms caused by the specific genetic variation. The current and future in-silico edgotyping tools present a cheap and fast solution to deal with the rapidly growing datasets of discovered mutations. Our work shows the feasibility of a large- scale in-silico edgetic study and revealing insights into the orchestrated play of mutations inside a complex PPI network. We also expect for our module detection method to become a part of the common toolbox for the disease module analysis, facilitating the discovery of new disease markers.

Abstract:

In this information age, the Internet has found a role in various industries such as transportation, advertising, etc. The travel industry, in which communication between travellers and travel service providers is a very important component, has as much potential as any other industry to make full use of this new medium. Already, most travel agencies and travel service providers promote their products and services using web sites. Searching for information online is now seen by many people as a way to save time and cost, especially in their travel activities. In order to fully deploy the Internet within the travel industry, understanding the use of the Internet in tourism is critical. This research sets out initially to examine the role and the impact of the Internet in the whole of the travel industry. But in order to define an achievable scope of work and because of its importance in South Africa at this time, tourism within the travel industry was chosen as the focus of the work.

Abstract:

This thesis presents a comparative study of four Network Access Control (NAC) technologies; Trusted Network Connect by the Trusted Computing group, Juniper Networks, Inc.’s Unified Access Control, Microsoft Corp.’s Network Access Protection, and Cisco Systems Inc.’s Network Admission Control. NAC is a vision, which utilizes existing solutions and new technologies to provide assurance that any device connecting to a network policy domain is authenticated and is subject to the network’s policy enforcement. Non-compliant devices are isolated until they have been brought back to a complaint status. We compare the NAC technologies in terms of architectural and functional features they provide.

There is a race of NAC solutions in the marketplace, each claiming their own definition and terminology, making it difficult for customers to adopt such a solution, resulting in much uncertainty. The NAC paradigm can be classified into two categories: the first category embraces open standards; the second follows proprietary standards. By selecting these architectures, we cover a representative set of proprietary and open standards-based NAC technologies.

This study concludes that there is a great need for standardization and interoperability of NAC components and that the four major solution proposals that we studied fall short of the desired interoperability. With standards, customers have the choice to adopt solution components from different vendors, selecting, what is commonly referred to as the best of breed. One example for a standard technology that all four NAC technologies that we studied did adopt is the IEEE’s 802.1X port-based access control technology. It is used to control endpoint device access to the network.

One shortcoming that most NAC architectures (with the exception of Trusted Network Connect) have in common, is the lack of a strong root-of-trust. Without it, clients’ compliance measurements cannot be trusted by the policy server whose task is to assess each client’s policy compliance.

The introduction of wireless communications between vehicles will enable many useful applications to enhance road traffic safety as well to increase efficiency. The standardization of IEEE 802.11p, being an amendment to IEEE 802.11 intended for VANETS, faces many challenges. In Europe a 30 MHz spectrum at 5.9 GHz have been dedicated for ITS and this spectrum has to be used to its full potential. For this reason this thesis compares a 20 MHz wide frequency channel with a 10 MHz wide through measurements using 802.11p hardware. The measurements were conducted on a highway with relative speeds of up to 240 km/h. The results from these initial measurements show that a 20 MHz channel does not perform worse than a 10 MHz channel despite the high relative speeds and large metal signs scattering the signals. What enabled this thesis to do the measurements was Halmstad University‟s participation in the Grand Cooperative Driving Challenge (GCDC) 2011. In GCDC nine teams mostly from Europe competed in having the vehicle that had the best behaviour in a platoon of vehicles using cooperative adaptive cruise control (CACC), the CACC algorithm controlled the vehicles‟ acceleration and breaking autonomously based on in-vehicle sensors and communicated messages between the vehicles in the platoon using 802.11p. This thesis implemented the communication part of Halmstad University‟s vehicle. The challenge was held in Helmond, Holland, May 14-15, 2011. Halmstad University‟s team finished in second place.

Abstract:

Nella attuale ricerca biomedica un passo fondamentale verso una comprensione dei meccanismi alla radice di una malattia è costituito dalla identificazione dei disease modules, cioè quei sottonetwork dell'interattoma, il network delle interazioni tra proteine, con un alto numero di alterazioni geniche. Tuttavia, l'incompletezza del network e l'elevata variabilità dei geni alterati rendono la soluzione di questo problema non banale. I metodi fisici che sfruttano le proprietà dei processi diffusivi su network, dei quali mi sono occupato in questo lavoro di tesi, sono quelli che consentono di ottenere le migliori prestazioni. Nella prima parte del mio lavoro, ho indagato la teoria relativa alla diffusione ed ai random walk su network, trovando interessanti relazioni con le tecniche di clustering e con altri modelli fisici la cui dinamica è descritta dalla matrice laplaciana. Ho poi implementato un tecnica basata sulla diffusione su rete applicandola a dati di espressione genica e mutazioni somatiche di tre diverse tipologie di cancro. Il metodo è organizzato in due parti. Dopo aver selezionato un sottoinsieme dei nodi dell'interattoma, associamo ad ognuno di essi un'informazione iniziale che riflette il "grado" di alterazione del gene. L'algoritmo di diffusione propaga l'informazione iniziale nel network raggiungendo, dopo un transiente, lo stato stazionario. A questo punto, la quantità di fluido in ciascun nodo è utilizzata per costruire un ranking dei geni. Nella seconda parte, i disease modules sono identificati mediante una procedura di network resampling. L'analisi condotta ci ha permesso di identificare un numero consistente di geni già noti nella letteratura relativa ai tipi di cancro studiati, nonché un insieme di altri geni correlati a questi che potrebbero essere interessanti candidati per ulteriori approfondimenti.Attraverso una procedura di Gene Set Enrichment abbiamo infine testato la correlazione dei moduli identificati con pathway biologici noti.

Abstract:

L'avènement de l'Internet des Objets a permis de déployer de nombreux réseaux de capteurs sans-fil. Ces réseaux sont utilisés dans des domaines aussi variés que l'agriculture, l'industrie ou la ville intelligente, où ils permettent d'optimiser finement les processus. Ces appareils sont le plus souvent alimentés par des piles ou batteries, ce qui limite leur autonomie. De plus, il n'est pas toujours possible ou financièrement viable de changer ou recharger les batteries. Une solution possible est d'alimenter ces capteurs en récupérant l'énergie présente dans l'environnement alentour. Ces sources d'énergie sont cependant peu fiables, et le capteur doit être capable d'éviter de vider complètement sa réserve d'énergie. Afin de moduler sa consommation d'énergie, le capteur peut adapter sa qualité de service à ses capacités énergétiques. L'appareil peut ainsi fonctionner en continu sans interruption de service. Cette thèse présente les méthodes utilisées pour la conception d'un capteur entièrement autonome alimenté par récupération d'énergie ambiante, communiquant sur un réseau longue portée LoRa. Afin d'assurer l'alimentation électrique, une carte permettant de récupérer de l'énergie depuis plusieurs sources d'énergie simultanément a été conçue. Un module logiciel de gestion d'énergie a ensuite été développé afin de calculer un budget énergétique que le capteur peut dépenser, et choisir la meilleure manière de dépenser ce budget pour exécuter une ou plusieurs tâches. Ce travail a ainsi permis le développement d'un prototype de produit industriel entièrement autonome en énergie
The advent of the Internet of Things has enabled the roll-out of a multitude of Wireless Sensor Networks. These networks can be used in various fields, such as agriculture, industry or the smart city, where they facilitate fine optimization of processes. These devices are often powered by primary or rechargeable batteries, which limits their battery life. Moreover, it is sometimes not possible or financially viable to change and/or recharge these batteries. A possible solution is to harvest energy from the environment to power these sensors. But these energy sources are unreliable, and the sensor must be able to prevent the complete depletion of its energy storage. In order to adapt its energy consumption, the node can match its quality of service to its energetical capabilities. Thus, the device can continuously operate without any service interruption. This thesis presents the methods used for the conception of a completely autonomous sensor, powered by energy harvesting and communicating through a long range LoRa network. In order to ensure its power supply, a board has been designed to harvest energy from multiple energy sources simultaneously. A power management software module has then been developed to calculate an energy budget the sensor can use, and to choose the best way to spend this budget over one or multiple tasks. This work has enabled the development of an energy autonomous industrial sensor prototype

Abstract:

Published Article
The Water Administration System (WAS) is designed to be a management tool for irrigation schemes and water offices that want to manage their water accounts and supply to clients through canal networks, pipelines and rivers. The ultimate aim of WAS is to optimize irrigation water management and minimize management-related distribution losses in irrigation canals. This research project focus on the implementation of the water release module of the WAS program at the Vaalharts irrigation scheme. WAS consists of four modules that are integrated into a single program that can be used on a single PC, a PC network system (in use currently at Vaalharts) or a multi-user environment. These modules can be implemented partially or as a whole, depending on the requirements of the specific scheme or office. The four modules are an administration module, a water request module; water accounts module and a water release module. The first three modules are already implemented at Vaalharts, while module four is implemented only partially. This module links with the water request module and calculates water releases for the main canal and all its branches allowing for lag times and any water losses and accruals. Any researcher in this field should first understand where water comes from and how it will be utilized before any calculations are attempted. Only then manipulation of the release volume can commence. To precisely calculate this water release, accurate data is needed to ensure that the correct volume of water is released into the canal network. This can be done by verifying existing data with field data. To optimize the management of the irrigation scheme the fully implemented WAS program need to be installed and running at the scheme. A series of data and calculation verification needs to be executed. The exercise will show the adequacy and correctness of the available database WAS uses to do the release calculation from. This will ensure improved management of the irrigation scheme, catchment and water resource sustainability. It is planned that the information generated from this project will be used in the compilation of an integrated catchment management information system, currently underway in the school of Civil Engineering and Built Environment at the Central University of Technology, Free State, South Africa.

Abstract:

The main purpose of this thesis is to test a communications solution for the second to largest refugee settlement in the world, Bidi Bidi. A solution where it is possible to inform the refugees with necessary information, for example that the water at a specific location is currently contaminated or that food is provided at another location. The idea is to use nRF24L01+ modules which operate in the 2.4 GHz frequency band and send information through various ways. This includes turning LEDs' on and off, sending text Strings and streaming audio. The results showed that the modules are too unreliable for a refugee settlement. They also showed that it is not possible to send other types' of data while streaming audio, but there could be workarounds. It is clear that more knowledge and further investigations are needed.

Abstract:

Over the past two decades of HIV research, effective vaccine candidates have been elusive. Traditionally viral research has been characterized by a gene -by-gene approach, but in the light of the availability of complete genome sequences and the tractable size of the HIV genome, a genomic approach may improve insight into the biology and epidemiology of this virus. A genomic approach to finding HIV vaccine candidates can be facilitated by the use of genome sequence visualization. Genome browsers have been used extensively by various groups to shed light on the biology and evolution of several organisms including human, mouse, rat, Drosophila and C.elegans. Application of a genome browser to HIV genomes and related annotations can yield insight into forces that drive evolution, identify highly conserved regions as well as regions that yields a strong immune response in patients, and track mutations that appear over the course of infection. Access to graphical representations of such information is bound to support the search for effective HIV vaccine candidates. This study aimed to answer the question of whether a tool or application exists that can be modified to be used as a platform for development of an HIV visualization application and to assess the viability of such an implementation. Existing applications can only be assessed for their suitability as a basis for development of an HIV genome browser once a well-defined set of assessment criteria has been compiled.

Abstract:

SIP is receiving much attention these days and it seems to be the most promising candidate as a signaling protocol for the current and future IP telephony services. Realizing this, there is the obvious need to provide a certain level of quality comparable to the traditional telephone service signalling system. Thus, we identified the major costs of SIP, which were found to be delay and security. This thesis discusses the costs of SIP, the solutions for the major costs, and the development of a low cost SIP application. The literature review of the components used to develop such a service is discussed, the networks in which the SIP is used are outlined, and some SIP applications and services previously designed are discussed. A simulation environment is then designed and implemented for the instant messaging service for wireless devices. This environment simulates the average delay in LAN and WLAN in different scenarios, to analyze in which scenario the system has the lowest costs and delay constraints.

Abstract:

The objective of the thesis research is to design such vertical handoff decision algorithms in order for mobile field workers and other mobile users equipped with contemporary multimode mobile devices to communicate seamlessly in the NGWN. In order to tackle this research objective, we used fuzzy logic and fuzzy inference systems to design a suitable handoff initiation algorithm that can handle imprecision and uncertainties in data and process multiple vertical handoff initiation parameters (criteria)
used the fuzzy multiple attributes decision making method and context awareness to design a suitable access network selection function that can handle a tradeoff among many handoff metrics including quality of service requirements (such as network conditions and system performance), mobile terminal conditions, power requirements, application types, user preferences, and a price model
used genetic algorithms and simulated annealing to optimise the access network selection function in order to dynamically select the optimal available access network for handoff
and we focused in particular on an interesting use case: vertical handoff decision between mobile WiMAX and UMTS access networks. The implementation of our handoff decision algorithm will provide a network selection mechanism to help mobile users select the best wireless access network among all available wireless access networks, that is, one that provides always best connected services to users.

Abstract:

Information and Communication Technologies (ICTs) have been widely deployed in developmental programs and this has lead to the creation of a new field – ICT for Development (ICT4D). Within the context of ICT4D, various e-services are being developed, including e-Commerce, e-Government, e-Health and e-Judiciary. ICT4D projects allow Small, Medium and Micro Enterprises (SMMEs) in rural areas to increase sales and gain a market share in the global market. However, many of these ICT4D projects do not succeed, because they fail to bring enough financial value to SMMEs due to the form they currently have. An obvious example is e-Commerce, which should be a source of revenue for business organizations, but most often is not. This thesis presents the design and implementation of a rewarding and negotiation application for a shopping portal to improve the marketing of products for rural entrepreneurs. The shopping portal has been set up for the Dwesa community, a marginalized area in the Eastern Cape province of South Africa. The proposed system, called the Dwesa Rewarding Program (DRP) enables customers buying online to get points for some of the activities carried out on the shopping portal. It also allows customers to negotiate and make offers whilst purchasing and get rewarded for buying online. The novelty of the system is in its flexibility and adaptability. One achievement of this system is the establishment of negotiation rules which allows fairness in rewarding customers. This should in turn lead to increased sales on the e-Commerce platform in marginalized areas and subsequently increased effectiveness of ICT4D for socio-economic development

Abstract:

ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada
As requirements for the amount of test data continues to increase, instrumentation engineers are under pressure to deploy data acquisition systems that reduce the amount of associated wiring and overall system complexity. Smart sensor buses have been long considered as one approach to address this issue by placing the appropriate signal conditioners close to their respective sensors and providing data back over a common bus. However, the inability to adequately synchronize the operation of the sensor bus to the system master, which is required to correlate analog data measurements, has precluded their use. The ongoing development and deployment of smart sensor buses has reached the phase in which integration into a larger data acquisition system environment must be considered. Smart sensor buses, such as IntelliBus™, have their own unique mode of operation based on a pre-determined sampling schedule, which however, is typically asynchronous to the operation of the (master or controller) data acquisition system and must be accounted for when attempting to synchronize the two systems. IRIG Chapter 4 type methods for inserting data into a format, as exemplified by the handling of MIL-STD-1553 data, could be employed, with the disadvantage of eliminating any knowledge as to when a particular measurement was sampled, unless it is time stamped (similar to the time stamping function that is provided to mark receipt of 1553 command words). This can result in excessive time data as each sensor bus can manage a large number of analog sensor inputs and multiple sensor buses must be accommodated by the data acquisition system. The paper provides an example, using the Boeing developed IntelliBus system and the L3 Communications - Telemetry East NetDAS system, of how correlated data can be acquired from a smart sensor bus as a major subsystem component of a larger integrated data acquisition system. The focus will be specifically on how the IntelliBus schedule can be synchronized to that of the NetDAS formatter. Sample formats will be provided along with a description of how a standalone NetDAS stack and an integrated NetDAS-IntelliBus system would be programmed to create the required output, taking into account the unique sampling characteristics of the sensor bus.

Abstract:

La diversité du monde vivant repose pour une large part sur la diversité des protéines codées dans les génomes. Comment une telle diversité a-t-elle été générée ? La théorie classique postule que cette diversité résulte à la fois de la divergence de séquence et de la combinatoire des arrangements de protéines en domaines à partir de quelques milliers de domaines anciens, mais elle n’explique pas les nombreuses protéines orphelines.Dans cette thèse, nous avons étudié l’évolution des protéines du point de vue de leur décomposition en domaines en utilisant trois bases de données : HOGENOM (familles de protéines homologues), Pfam (familles de domaines expertisées) et ProDom (familles de modules protéiques construites automatiquement). Chaque famille d’HOGENOM a ainsi été décomposée en domaines de Pfam ou modules de ProDom. Nous avons modélisé l’évolution de ces familles par un réseau Bayésien basé sur l’arbre phylogénétique des espèces. Dans le cadre de ce modèle, on peut reconstituer rigoureusement les scénarios d’évolution les plus probables qui reflètent la présence ou l’absence de chaque protéine, domaine ou module dans les espèces ancestrales. La mise en relation de ces scénarios permet d’analyser l’émergence de nouvelles protéines en fonctions de domaines ou modules ancestraux. L’analyse avec Pfam suggère que la majorité de ces événements résulte de réarrangements de domaines anciens, en accord avec la théorie classique. Cependant une part très significative de la diversité des protéines est alors négligée. L’analyse avec ProDom, au contraire, suggère que la majorité des nouvelles protéines ont recruté de nouveaux modules protéiques. Nous discutons les biais de Pfam et de ProDom qui permettent d’expliquer ces points de vue différents. Nous proposons que l’émergence de nouveaux modules protéiques peut résulter d’un turn-over rapide de séquences codantes, et que cette innovation au niveau des modules est essentielle à l’apparition de nombreuses protéines nouvelles tout au long de l’évolution
The diversity of life derives mostly from the variety of proteins coded in genomes. How did evolution produce such a tremendous diversity ? The classical theory postulates that this diversity results both from sequence divergence and from the combinatorial arrangements of a few thousand primary protein domain types. However this does not account for the increasing number of entirely unique proteins as found in most genomes.In this thesis, we study the evolution of proteins from the point of view of their domain decomposition and rely on three databases : HOGENOM (homologous protein families), Pfam (manually curated protein domain families) and ProDom (automatically built protein module families). Each protein family from HOGENOM has thus been decomposed into Pfam domains or ProDom modules. We have modelled the evolution of these families using a Bayesian network based on the phylogenetic species tree. In the framework of this model, we can rigorously reconstitute the most likely evolutionary scenarios reflecting the presence or absence of each protein, domain or module in ancestral species. The comparison of these scenarios allows us to analyse the emergence of new proteins in terms of ancestral domains or modules. Pfam analysis suggests that the majority of protein innovations results from rearrangements of ancient domains, in agreement with the classical paradigm of modular protein evolution. However a very significant part of protein diversity is then neglected. On the other hand ProDom analysis suggests that the majority of new proteins have recruited novel protein modules. We discuss the respective biases of Pfam and ProDom underlying these contrasting views. We propose that the emergence of new protein modules may result from a fast turnover of coding sequences and that this module innovation is essential to the emergence of numerous novel proteins throughout evolution

Abstract:

This study utilized large-scale gene expression data to define the regulatory networks of genes expressing in the hippocampus to which multiple disease pathologies may be associated. Specific aims were: ident i fy key regulatory transcription factors (TFs) responsible for observed gene expression patterns, reconstruct transcription regulatory networks, and prioritize likely TFs responsible for anatomically restricted gene expression. Most of the analysis was restricted to the CA3 sub-region of Ammon&rsquo
s horn within the hippocampus. We identified 155 core genes expressing throughout the CA3 sub-region and predicted corresponding TF binding site (TFBS) distributions. Our analysis shows plausible transcription regulatory networks for twelve clusters of co-expressed genes. We demonstrate the validity of the predictions by re-clustering genes based on TFBS distributions and found that genes tend to be correctly assigned to groups of previously identified co-expressing genes with sensitivity of 67.74% and positive predictive value of 100%. Taken together, this study represents one of the first to merge anatomical architecture, expression profiles and transcription regulatory potential on such a large scale in hippocampal sub-anatomy.

Abstract:

Inflammatory bowel disease encompasses a variety of heterogeneous chronic inflammatory diseases that affect the gastrointestinal tract, where Crohn’s disease and ulcerative colitis are the principal examples. The etiology of these, and many other complex human diseases, remain largely unknown and therefore pose relevant targets for novel research strategies. One such strategy is the in silico application of network theory derived methods to data sourced from publicly available repositories of e.g. gene expression data. Specifically, methods generating graphs of interconnected elements enriched by differentially expressed genes—disease modules—were inferred with data available through the Gene Expression Omnibus. Based on a previous method, the current project aimed to evaluate disease modules, combined from stand-alone inferential methods, in disease consensus modules: representing pathophenotypical motifs for the diseases of interest. The modules found to be significantly enriched by genome-wide association study inferred single-nucleotide polymorphisms, as validated using the Pathway Scoring Algorithm, were subsequently subjects for further analysis using Kyoto Encyclopedia of Genes and Genomes-pathway enrichment, and literature searches. The results of this study adheres to previous findings relating to the employed method, but lack any novelty pertaining the diseases of interest. However, the results substantiate the preceding methods’ conclusion by including parameters that increase statistical validity. In addition, the study contributed to peripheral results concerning both the methodology of consensus module methods, and the elucidation of inflammatory bowel disease etiology and disease subtype differentiation, that pose interesting subjects for future investigation.

The goal of this thesis is to introduced the principles of access control technologies, the General Data Protection Regulation and the software for data leakage protection. An essential part of the work is a draft and implementation of the expansion module for user device authentication including shared storage access authorization. Therefore, this module allows to verify whether a user can access shared corporate resources. It also allows to enable or disable access based on specified attributes, such as the type of the protected service or user permission. The basic verification of the module's functionality is realized through different sets of tests and a virtual environment that simulates the corporate environment. The result of the draft is a module that allows to verify access based on the device, and this module is moreover integrated into the Safetica security platform.

Abstract:

The thesis took the general question of responsive curriculum development which meets both the needs of work and those of the academy as its starting point. The rationale for the topic flows out of education policy and societal pressures worldwide which are calling for an ever greater responsiveness from higher education to the workplace in the twenty-first century. Responsiveness to work requires collaborative and integrative work between communities of academic and non-academic practitioners. Differences between knowledge and practices at work and within the academy are broadly acknowledged in the literature, yet the ensuing nature and complexity of interactions between these two communities in curriculum design on the ground is poorly understood. A key point is to recognize that integration as such cannot be the goal
the differences remain, but have to turned into productive collaboration and joint development, for example, of a curriculum.

This thesis addresses the provision of life-cycle management, which is only one carrier grade characteristic, for a SoftBridge application, which is an example of IP communication applications. A SoftBridge provides semi-synchronous multi-modal IP-based communication. The work related to IP-Telecommunication integrated services and the SoftBridge is analyzed with respect to life-cycle management in a literature review. It is suggested to use an Application Server in a Next Generation Network (NGN) to provide life-cyclemanagement functionality for IP-Telecommunication applications. In this thesis, the Application Server is represented by a JAIN Service Logic Execution Environment(JSLEE), in which
a SoftBridge application can be deployed, activated, deactivated, uninstalled and upgraded online.Two methodologies are applied in this research: exploratory prototyping, which evolves the development of a SoftBridge application, and empirical comparison, which is concerned with the empirical evaluation of a SoftBridge application in terms of carriergrade capabilities. A SoftBridge application called SIMBA
provides a Deaf Telephony service similar to aprevious Deaf Telephony SoftBridge, However, SIMBA&rsquo
s SoftBridge design and implementation are unique to this thesis. In order to test the life-cycle
management ability of SIMBA, an empirical evaluation is carried out including the experiments oflife-cycle management and call-processing performance. The final experimental results of the evaluation show that a JSLEE is able to provide life-cycle management for SIMBA without causing a significant decrease in performance. In conclusion, the life-cycle management can be provided
or a SoftBridge application by using an Application Server such as a JSLEE. Futhermore, the results indicate that
approach of using Application Server (JSLEE) integration should be
sufficiently general to provide life cycle management, and indeed other carrier grade capabilities, for other IP communication applications. This allows IP communication applications to be

integrated into an NGN.

Thesis (MTech (Information Technology))--Peninsula Technikon,Cape Town, 2004
Higher education and online discussions are an integral part of collaboratively based e-Learning systems. However, there problems can be associated with current online discussion models. For example, it can be easy to set open-ended discussions which attract little participation and to assess contributions can be difficult or time-consuming. Students may not achieve the expected learning outcomes without proper structure and management in online discussions. This paper proposes to design and implement a discussion forum object to function within the architectural constraints of an existing Oss learning management system (to meet target user requirements) that is a web-based environment for online discussions where the facilitator can structure each discussion according to its nature and where learning requirements are using already designed templates.

Thesis (MTech (Information Technology))--Peninsula Technikon, 2004
This dissertation was written in fulfillment of the requirements for the degree Master of Technology in the Faculty of Information Technology at the Peninsula Technikon in South Africa. The dissertation covers the introduction of the study; the reviews of the case, Free and Open Source Software; the discussion of methodology of software project management in terms of software engineering; the analysis of assessment methods; the techniques of using PHP, MySQL, Apache and CVS; and the implementation of a test module. The research represents the consideration of the problem, namely that there are few free assessment manager programmes that can be used for the quick and efficient deployment of academic assessments. An experimental research method was used to with the aim of solving the above problem. In other words, a test management system module had to be designed and implemented to function within the architectural constraints of a developing Open Source Software (OSS) Learning Management System (LMS), which is called Knowledge Environment for Web-based Learning Next Generation (KEWL.NextGen). The test management system is a module developed on Object-Oriented Programming (OOP) in PHP and MySQL application. The scripts of this test module are written under the KEWL.NextGen' application framework, which is based on a close approximation of model, view and controller (MVC) design III pattem. Now the entire source coding of the test module has been uploaded to Web site http://kngforge.uwc.ac.za. This test module can be used for the creation and management of an online test. It provides facilities to create a new test, and to preview, edit, delete and mark an existing test. Three question types have been achieved, namely multiple-choice, true/false and short answer.

Abstract:

When installing new network security cameras in buildings, the cameras are often connected to sensors via signal wires. Since most building already have internet and electricity drawn throughout the structure, the procedure of routing a new signal wire can be costly and time demanding. By replacing this wire with a wireless link, the cost and time it takes for the customer to install a camera could be reduced. The objective for this thesis is to investigate different wireless technologies used in short range, low power wireless communication networks such as PANs and LANs. Focusing on technologies used in the surveillance segment a decision will be made on which wireless technology that would suit as a link between a sensor and a camera for transmitting trigger signals. The technology will then be implemented in a proof-of-concept accessory, which can give an Axis Communications camera wireless functionality through it’s IO port.

Abstract:

Dans une optique de maximisation de la production et de réduction des coûts d’installation, de maintenance et d’entretien des trackers solaires, qui permettent d’orienter les modules photovoltaïques à haute concentration (HCPV), ces travaux de thèse se focalisent sur l’amélioration de la précision et la réduction du coût de la stratégie de génération de la trajectoire du tracker. Dans un premier temps, un simulateur de tracker HCPV est développé offrant une étude de l’influence de la performance du suivi du soleil sur la production des modules HCPV, permettant ainsi une étude et une comparaison des stratégies de génération de trajectoires. Le simulateur est basé sur un modèle comportemental de module HCPV monté sur tracker permettant de prédire la puissance maximale du module HCPV en fonction de l’erreur de position du tracker face au soleil, de l’ensoleillement direct et de la température. Une première stratégie de commande dite de référence a été implémentée sur ce simulateur. C’est une commande hybride qui repose sur un viseur solaire pour corriger l’erreur de poursuite par un calcul astronomique. Ensuite, afin d’améliorer les performances et de réduire les coûts de cette stratégie, une nouvelle approche sans capteur est développée en se basant sur une méthode d’optimisation du gradient de puissance pour la génération de la trajectoire du tracker. Une étude complémentaire est également exposée afin de mettre en évidence des algorithmes de recherche de la puissance maximale (MPPT) pouvant offrir des temps de réponse suffisamment rapides pour ne pas affecter la qualité de l’évaluation du gradient de puissance. Dans ce contexte, une commande MPPT P&O améliorée par un réseau de neurones à complexité réduite est proposée, assurant un compromis entre précision, simplicité et rapidité
This work focuses on improving the accuracy and on reducing the cost of the tracker generating trajectory strategy, in order to maximize the production and to reduce the installation and the maintenance cost of a solar tracker orienting high concentrated photovoltaic modules (HCPV). Initially, we propose a behavioral modeling of the HCPV module mounted on a dual axis tracker in order to study the influence of the tracking performance on the module power production. Then, this simulator can be used to test control strategies and to compare their performance. Firstly, a classical control strategy is implemented in the simulator. It is based on a hybrid control operating an astronomical calculation to follow the sun path, and a sun sensor to correct the tracking error. A sensorless strategy is proposed in this work to reduce the cost of the HCPV tracker control. This strategy is based on a gradient optimization algorithm to generate the tracker trajectory and to catch the sun path. Tested on the simulator, this strategy presents the same accuracy as the classical strategy while being less costly. The last study proposed in this thesis work concerns maximum power point tracking (MPPT) algorithms, in order to respond to a given problem relating to the practical implementation of gradient algorithm. In this context, we propose an original optimization of the P&O MPPT control with a neural network algorithm leading to a significant reduction of the computational cost required to train it. This approach, which is ensuring a good compromise between accuracy and complexity is sufficiently fast to not affect the quality of the evaluation of the gradient

Abstract:

The Master's thesis discusses the design and realization of electronic meter of volt-ampere characteristics using Wifi module ESP32. The device is designed to be able to measure the characteristic in the voltage range of +/- 20 V and current range of +/- 200 mA. The device is controlled by web interface. The user is able to connect to it with for example his or her smartphone. This interface enables the user to configure various parameters, including the range of measurement and the power restriction. Furthermore, it is possible to graphically display the measured characteristic and export the data. To be independent on the outer network, the ESP32 is operated as an access point, which is creating a new simple network without the internet connection. In the Master's thesis, the principle of voltage and current measurement is explained theoretically, the circuit connection of device and the printed circuit board are designed and the cover of the device is modeled. Also the process of creating the device according to the design is described and the cover of the device is printed on 3D printer. After that, the control program is designed, described and uploaded into the resulting device. Finally, the functionality of the device is tested by measuring the volt-ampere characteristics of a few components.
