Ortner, Jens, and Erik Ågren. "Automated Hydroponic system." Thesis, KTH, Skolan för industriell teknik och management (ITM), 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-264438.
Full textAbstract:
This report includes research into how to automate a small scale system for hydroponics. Hydroponics is a growing technique which features a soil-less environment were the plants roots are exposed to a nutrient-enriched water solution. The research focused mainly on how to regulate the pH and the level of nutrient in the water solvent and finding a system to automate that process. In the research fully grown basil plants were used as test specimens, with the plants roots submerged in a water solvent. The water solvent had sensors that were connected to a micro controller making it possible to monitor the presence of nutrients and pH in the solvent. If the micro controller deemed that the pH and/or the nutrient level was too high or too low, the micro controller would adjust the solvent by activating pumps adding pH down buffer solution and/or nutrient solution to the solvent. The research proved that a way to automate a small scale hydroponics system is by building a computerized system consisting of: • Micro controller. • pH sensor. •EC sensor (to measure nutrient level in solvent). • Temperature sensor. • Fluid pumps connected to pH- and nutrient reservoirsI denna rapport följer en forskning om hur ett system för hydroponics kan automatiseras. Hydroponics är en odlingsteknik som utesluter nyttjandet av jord. Istället får plantorna näring och vatten via en näringsrik vattenlösning som dess rötter är i kontakt med. Forskningen fokuserade huvudsakligen på hur man reglerar pH och nivån av näringsämnen i en vattenlösning och skapa ett system för att automatisera denna processen. I undersökningen användes fullvuxna basilikaväxter som prover med plantornas rötter nedsänkta i en vattenlösning. Vattenlösningen hade sensorer som var anslutna till en mikrostyrenhet som gjorde det möjligt att övervaka nivån av näringsämnen och pH i vattenlösningen. Om mikrokontrollen ansåg att pH- och/eller nivån av näringsämnen var felaktig så skulle mikrostyrenheten justera vattenlösningen. Detta skedde genom att mikrostyrenheten aktiverade vätskepumpar som tilsatte pH-buffer och/eller näringslösning. Forskningen visade att ett sätt att automatisera ett hydroponicsystem är att bygga ett datoriserat system som består utav: mikrostyrenhet. pH mätare. EC mätare (används för att mäta näringsnivån i vattenlösningen). Temperaturmätare. Vätskepumpar anslutna till behållare inehållandes pH- och näringslösning.

Astapenko, D. "Automated system design optimisation." Thesis, Loughborough University, 2010. https://dspace.lboro.ac.uk/2134/6863.
Full textAbstract:
The focus of this thesis is to develop a generic approach for solving reliability design optimisation problems which could be applicable to a diverse range of real engineering systems. The basic problem in optimal reliability design of a system is to explore the means of improving the system reliability within the bounds of available resources. Improving the reliability reduces the likelihood of system failure. The consequences of system failure can vary from minor inconvenience and cost to significant economic loss and personal injury. However any improvements made to the system are subject to the availability of resources, which are very often limited. The objective of the design optimisation problem analysed in this thesis is to minimise system unavailability (or unreliability if an unrepairable system is analysed) through the manipulation and assessment of all possible design alterations available, which are subject to constraints on resources and/or system performance requirements. This thesis describes a genetic algorithm-based technique developed to solve the optimisation problem. Since an explicit mathematical form can not be formulated to evaluate the objective function, the system unavailability (unreliability) is assessed using the fault tree method. Central to the optimisation algorithm are newly developed fault tree modification patterns (FTMPs). They are employed here to construct one fault tree representing all possible designs investigated, from the initial system design specified along with the design choices. This is then altered to represent the individual designs in question during the optimisation process. Failure probabilities for specified design cases are quantified by employing Binary Decision Diagrams (BDDs). A computer programme has been developed to automate the application of the optimisation approach to standard engineering safety systems. Its practicality is demonstrated through the consideration of two systems of increasing complexity; first a High Integrity Protection System (HIPS) followed by a Fire Water Deluge System (FWDS). The technique is then further-developed and applied to solve problems of multi-phased mission systems. Two systems are considered; first an unmanned aerial vehicle (UAV) and secondly a military vessel. The final part of this thesis focuses on continuing the development process by adapting the method to solve design optimisation problems for multiple multi-phased mission systems. Its application is demonstrated by considering an advanced UAV system involving multiple multi-phased flight missions. The applications discussed prove that the technique progressively developed in this thesis enables design optimisation problems to be solved for systems with different levels of complexity. A key contribution of this thesis is the development of a novel generic optimisation technique, embedding newly developed FTMPs, which is capable of optimising the reliability design for potentially any engineering system. Another key and novel contribution of this work is the capability to analyse and provide optimal design solutions for multiple multi-phase mission systems. Keywords: optimisation, system design, multi-phased mission system, reliability, genetic algorithm, fault tree, binary decision diagram

At every annual exam, the primary care physician uses a stethoscope to listen for cardiac abnormalities. This approach is non-invasive, inexpensive, and fast. It is also highly unreliable. Over 80% of the people referred to cardiologists as suffering from the most commonly diagnosed condition, mitral valve prolapse (MVP), do not have this condition. Working in conjunction with cardiologists at MGH, we developed a robust, low cost, easy to use tool that can be employed to diagnose MVP in the office of primary care physicians. The system fuses signals from an electronic stethoscope and a two-lead EKG, and uses software running on a desktop or laptop computer to make a diagnosis. We also provide a number of novel audiovisual diagnostic aids. These allow physicians to visualize both individual heart beats and a visual-prototypical heart beat constructed from a sequence of beats. They also permit doctors to listen to an audio-prototypical heart-beat, audio enhanced heart-beats that amplify clinically significant sounds, and slowed down heart-beats that make it easier to separate clinically relevant cardiac events. We tested our system on 51 patients. The number of false positives was reduced to approximately 10%. While there is no generally accepted statistic on false negatives, anecdotal experience indicates that our system also outperforms physicians in this respect.

Ocean Acidification is a reduction in pH caused by the absorption of atmospheric CO2. Low pH decreases the availability of calcium carbonate to shell and skeleton secreting marine animals such as mollusks and corals reducing their growth rates and even causing death. Thus, monitoring oceanic conditions has become more and more important, in particular there is a need for extensive measurements of carbonate chemistry parameters over both space and time. This paper presents a low-cost, automated benchtop measuring system for total alkalinity, one of the important parameters for monitoring marine carbonate chemistry. This system addresses the need for a low-cost alkalinity sensing system that can be deployed in great numbers to provide the large data sets needed for to measure and predict the impact of ocean acidification on the marine ecosystem. It is based on a two-point acid titration method. Tests of the prototype have shown that the system gives acceptable results comparable to manual measurements. With hermetic repackaging, the system could be field deployed on platforms such as AUVs or buoys.

Andrews, Robert. "An Automated Rule Refinement System." Queensland University of Technology, 2003. http://eprints.qut.edu.au/15788/.
Full textAbstract:
Artificial neural networks (ANNs) are essentially a 'black box' technology. The lack of an explanation component prevents the full and complete exploitation of this form of machine learning. During the mid 1990's the field of 'rule extraction' emerged. Rule extraction techniques attempt to derive a human comprehensible explanation structure from a trained ANN. Andrews et.al. (1995) proposed the following reasons for extending the ANN paradigm to include a rule extraction facility: * provision of a user explanation capability * extension of the ANN paradigm to 'safety critical' problem domains * software verification and debugging of ANN components in software systems * improving the generalization of ANN solutions * data exploration and induction of scientific theories * knowledge acquisition for symbolic AI systems An allied area of research is that of 'rule refinement'. In rule refinement an initial rule base, (i.e. what may be termed `prior knowledge') is inserted into an ANN by prestructuring some or all of the network architecture, weights, activation functions, learning rates, etc. The rule refinement process then proceeds in the same way as normal rule extraction viz (1) train the network on the available data set(s); and (2) extract the `refined' rules. Very few ANN techniques have the capability to act as a true rule refinement system. Existing techniques, such as KBANN, (Towell & Shavlik, (1993), are limited in that the rule base used to initialize the network must be a nearly complete, and the refinement process is limited to modifying antecedents. The limitations of existing techniques severely limit their applicability to real world problem domains. Ideally, a rule refinement technique should be able to deal with incomplete initial rule bases, modify antecedents, remove inaccurate rules, and add new knowledge by generating new rules. The motivation for this research project was to develop such a rule refinement system and to investigate its efficacy when applied to both nearly complete and incomplete problem domains. The premise behind rule refinement is that the refined rules better represent the actual domain theory than the initial domain theory used to initialize the network. The hypotheses tested in this research include: * that the utilization of prior domain knowledge will speed up network training, * produce smaller trained networks, * produce more accurate trained networks, and * bias the learning phase towards a solution that 'makes sense' in the problem domain. In 1998 Geva, Malmstrom, & Sitte, (1998) described the Local Cluster (LC) Neural Net. Geva et.al. (1998) showed that the LC network was able to learn / approximate complex functions to a high degree of accuracy. The hidden layer of the LC network is comprised of basis functions, (the local cluster units), that are composed of sigmoid based 'ridge' functions. In the General form of the LC network the ridge functions can be oriented in any direction. We describe RULEX, a technique designed to provide an explanation component for its underlying Local Cluster ANN through the extraction of symbolic rules from the weights of the local cluster units of the trained ANN. RULEX exploits a feature, ie, axis parallel ridge functions, of the Restricted Local Cluster (Geva , Andrews & Geva 2002), that allow hyper-rectangular rules of the form IF ∀ 1 ≤ i ≤ n : xi ∈ [ xi lower , xi upper ] THEN pattern belongs to the target class to be easily extracted from local functions that comprise the hidden layer of the LC network. RULEX is tested on 14 applications available in the public domain. RULEX results are compared with a leading machine learning technique, See5, with RULEX generally performing as well as See5 and in some cases outperforming See5 in predictive accuracy. We describe RULEIN, a rule refinement technique that allows symbolic rules to be converted into the parameters that define local cluster functions. RULEIN allows existing domain knowledge to be captured in the architecture of a LC ANN thus facilitating the first phase of the rule refinement paradigm. RULEIN is tested on a variety of artificial and real world problems. Experimental results indicate that RULEIN is able to satisfy the first requirement of a rule refinement technique by correctly translating a set of symbolic rules into a LC ANN that has the same predictive bahaviour as the set of rules from which it was constructed. Experimental results also show that in the cases where a strong domain theory exists, initializing an LC network using RULEIN generally speeds up network training, produces smaller, more accurate trained networks, with the trained network properly representing the underlying domain theory. In cases where a weak domain theory exists the same results are not always apparent. Experiments with the RULEIN / LC / RULEX rule refinement method show that the method is able to remove inaccurate rules from the initial knowledge base, modify rules in the initial knowledge base that are only partially correct, and learn new rules not present in the initial knowledge base. The combination of RULEIN / LC / RULEX thus is shown to be an effective rule refinement technique for use with a Restricted Local Cluster network.

Full textAbstract:
In real-word manufacturing environments, finding the right job sequences and their associated schedules when resource, precedence, and timing constraints are imposed is a difficult task. For most practical problems classical scheduling easily leads to an exponential growth in the number of possible schedules. Moreover, a decision time period of hours or even minutes is too long. Good solutions are often needed in real-time. The problem becomes even more complicated if changes, such as new orders or resource breakdowns, occur within the manufacturing system. One approach to overcome the challenges of solving classical scheduling problems is the use of distributed schemes such as agent or holonic-based control architectures.
This dissertation presents an innovative control architecture that uses the holonic concept, capable of delivering good solutions when applied in dynamic environments. The general holonic control framework presented in this research has specific characteristics not found in others reported so far. Using a modular approach it takes into account all the categories of hardware and software resources of a manufacturing system. Due to its modularity, the holonic control framework can be used for assigning and scheduling different task types, separately or simultaneously. Thus, it can be used not only for assigning and scheduling transport tasks, but also for finding feasible solutions to the job assignment and scheduling of processing tasks, or to better utilize the auxiliary equipment and devices in a manufacturing system.
In the holonic system, under real-time constraints, a feasible schedule for the material handling resources emerges from the combination of individual holon's schedules. Internal evaluation algorithms and coordination mechanisms between the entities in the architecture form the basis for the resultant schedules. The experimental results obtained show a percentage difference between the makespan values obtained using the holonic scheduling approach and the optimal values of under seven percent. Since current control systems in use in industry lack the ability to adapt to dynamic manufacturing environments, the holonic architecture designed and the tests performed in this research could be a part in the effort to build the foundations for the control systems of the next generation manufacturing systems.Ph.

Full textAbstract:
In this thesis, I/O signal recognizers, called VIRTUALBLOCKS, are synthesized to interface with a SYSTEM UNDER TEST (SUT). Methods for automated synthesis of virtualblocks allow us to simulate environment interfaces with SUT and also perform fault detection on SUT. Such methods must be able to recognize incoming sequences of signals from SUT, and upon the signal recognition determine the proper outgoing sequences of signals to SUT. We characterize our systems into four distinctive systems: system under test, AUXILIARY SYSTEM, controller and external environment. The auxiliary system is represented as a form of condition system Petri net (virtualblocks) and interacts with SUT along with the interaction among the controller and the external environment. Fault detection is performed by subsystems called DETECTBLOCKS synthesized from the virtualblocks. We present construction procedures for virtualblocks andamp; detectblocks and discuss the notion of LEGALITY and DETECTABILITY. Finally, we illustrate our approach using a model of a scanner control unit.

Through the power of the internet, documents can be delivered almost instantaneously. Communications processes can happen faster. Existing systems may be centralized (or made sharable) and automated applications can be created. The concept of automated applications can be extended to many fields of endeavor, so that an Automated Submission System for Law Reviews is an attractive project. A distinctive feature of Law Reviews is that students are reviewing submissions from professors, other professionals, or even from other students. The product of this research is the compilation of system requirements, which dictated the data and business model. By contacting law students actively participating in Law Review Boards, as well as professors, the data model was enhanced. It was extremely important to assure that the system was useful enough so that it generated workflow benefits, to entice Law Reviews to adopt the system. The Automated Submission System for Law Reviews would facilitate the submission process and communication between Authors and Reviewers. The Automated Submission System for Law Review Articles will prove to be extremely convenient and attractive for both, Law Reviews and Authors, since it is a centralized system that provides information for all parties involved. Efficiency and usability are the key; the system provides these two essential elements.

Sleep scoring involves classification of polysomnographic data into the various sleep
stages as defined by Retschaffen and Kales. This process is time-consuming and
laborious as it involves experts visually scoring the data. During recent years, there has
been an increasing focus on automated sleep scoring systems and professional software
programs are finding increased use. However, these systems are not relied on for scoring
and are often used as a tool that facilitates easy visual scoring.
This thesis proposes a neural network based approach to automatic sleep scoring
using LabVIEW. Effort has been made to give the sleep expert more control over key
parameters such as the frequency bands, and thus come up with scores that are more in
agreement with the individual scorer than being a rigid interpretation of the R&K rules.
Though this thesis is limited to the development of an offline software program, given
the data acquisition facilites in LabVIEW, a complete system from data acquisition to
sleep hypnograms is a fair possibility.

Full textAbstract:
Verifying the reliability and functionality of a complex system like a trading system is highly demanding since failure in such a system can cause serious economic problems. Automated random testing is a good solution to find new and rare failures in such a system. Test cases in random testing usually contain a long sequence of actions that debugging them manually to find the root cause of the failure is a very boring and tiresome task. This thesis aims to create a model for automating the task of the debugging to reduce the failed test case to an equivalent test case that only contains relevant actions that together cause the failure. Delta debugging is the core algorithm of the model that simplifies a failed test case by successive testing. The target of the project is TRADExpress system of Cinnober Financial Technology AB. The model is integrated to the random testing framework of the TRADExpress system.

Merging of clinical systems and medical databases, or aggregation of information from disparate databases, frequently requires a process where vocabularies are compared and similar concepts are mapped. Using a normalization phase followed by a novel alignment stage inspired by DNA sequence alignment methods, automated lexical mapping can map terms from various databases to standard vocabularies such as UMLS (Unified Medical Language System) and SNOMED (the Systematized Nomenclature of Medicine). This automated lexical mapping was evaluated using a real-world database of consultation letters from Children's Hospital Boston. The first phase involved extracting the reason for referral from the consultation letters. The reasons for referral were then mapped to SNOMED. The alignment algorithm was able to map 72% of equivalent concepts through lexical mapping alone. Lexical mapping can facilitate the integration of data from diverse sources and decrease the time and cost required for manual mapping and integration of clinical systems and medical databases.

The construction industry needs an accurate real-time positioning system. Such a system, if successfully implemented, would lead to significant increases in the performance of many construction operations. This thesis presents the Automated Laser Position System (ALPS) for accurate real-time positioning. ALPS is a spin-off of the Automated Position And Control System (APAC) research, sponsored by the National Science Foundation under grant DMC-8717476.
The ALPS concept has three primary components: a rotation laser, laser detectors and a central processing unit. ALPS generates both horizontal (X,Y) and vertical (Z) position information. It is mathematically predicted that ALPS could produce accuracies of ± 17 mm in the horizontal and ± 5,9 mm in the vertical, at a range of 400 m. Position measurements would be updated 50 times a second.

The purpose of this research is to explore the operational characteristics of a Maglev-based Automated Highway System and how it would interact with freeway operations. The extension of traditional traffic flow phenomenon, including weaving, merging, and stopping distance, into the automated system is looked at. These are also extended into platoon operations and their effect on such properties as gap control and ultimately the capacity of such a system. The ability to incorporate an AHS system into the existing Interstate Highway System is investigated. This includes placing the magways in the right-of-way of the highway system and interfacing the AHS with the existing freeways. A model is developed and run to simulate the assignment of traffic between the freeway and the guideway links. Both operational concepts of user equilibrium and system optimal conditions are explored, and equations are found to estimate the amount of traffic which can be found on the links based on the total traffic volume.Master of Science

Accurate image classification is one of the core challenges in computer vision. At the annual AUVSI SUAS competition, this challenge is faced in the form of ground target classification from an unmanned aerial vehicle (UAV). Additionally, due to the constraints imposed by the UAV platform, the system design must consider factors such as size, weight, and power consumption. To meet performance requirements while respecting such limitations, the system was broken into two subsystems: an onboard subsystem and a ground based subsystem. This design allows the onboard subsystem, comprised of a DSLR camera and single-board computer, to capture ground target images and perform rudimentary target detection and localization. For further processing and to ultimately classify the targets in each image, data packets are sent to the ground-based subsystem via a 5 GHz wireless link. Convolutional networks are utilized on the ground to achieve state-of-the-art accuracy in classification.

Full textAbstract:
Radio networks can provide reliable communication for rural intelligent transportation systems (ITS). Engineers manually design these radio networks by selecting tower locations and equipment while meeting a series of constraints such as coverage, bandwidth, maximum delay, and redundancy, all while minimizing network cost. As network size and constraints grow, the design process can quickly become overwhelming. In this thesis we model the network design problem (NDP) as a generalized Steiner tree-star (GSTS) problem. Any solution to the minimum Steiner tree (MST) problem on a constructed GSTS graph will directly identify the tower locations and equipment needed to build the network at an optimal cost. The direct MST solution can only satisfy coverage constraints. Because the MST problem is known to be NP-hard, our research applies ant colony optimization (ACO) to find near-optimal MST solutions. Using ACO also allows us to meet bandwidth, maximum delay, and redundancy constraints. We verify that our approach finds near-optimal designs by comparing it against a 2-approximation algorithm in several different scenarios.

Previous issue date: 2010Distributed systems are composed of geographically distributed computing elements that belong to multiple administrative domains and are controlled by multiple entities. These characteristics from distributed systems make hard the task of testing and evaluating software for this platform, because it is unlikely that testers/system or policy evaluators are able to acquire repeatedly the same re- sources, for the same amount of time, and under the same network conditions, which are paramount requirements for enabling reproducible and controlled tests in software under development. An al- ternative to experiments in real testbeds is emulation, where a model of a system hosts the actual software under test. Virtualization technology enables development of efficient emulators because it offers means for resources multiplexing and isolation. Even though virtualization makes easier development of emulators, there are few efforts in isolating testers/system or policy evaluators from operation of the virtualization tools and environment. This thesis presents Automated Emulation Framework (AEF), which applies virtualization and systems management technology in a cluster of workstations to provide testers/system or policy evaluators with a tool for automated emulation of distributed systems. Three main activities are performed by AEF. First, it performs the mapping of virtual machines that represents nodes from the emulated distributed environment to cluster nodes and emulated links between virtual machines to paths in the physical network; second, it performs automated installation and configuration of virtual machines in the cluster and virtual network in the cluster network; third, it performs automated configuration and triggering of experiments in the emulated system, monitoring and control of environment and applications, and system reconfigu- ration in case of violations in the tester/system or policy evaluator demands. Regarding the first activity, the mapping problem is formally defined and four heuristics for solution of the problem are developed and evaluated with the use of discrete-event simulation. Regarding the last two activities, AEF architecture is described in details. Furthermore, an AEF prototype is developed and evalu- ated by execution of experiments in the context of grid computing. Experiment results show that implementation of the architecture is feasible and that AEF can be a valuable tool for repeatable and controllable distributed systems experimentation.

The submission of manuscripts by Authors to Law Reviews is presently an inefficient process for both parties. The integration of technology allows for improvements to this process as can be seen in ExpressOTM and the Stanford Law Review's Electronic Submission System. The Automated Law Review Submission System (ALRSS) was developed to make the submission process even more efficient and effective than present systems allow. This is a software design thesis with emphasis on the System Requirements developed for the ALRSS. The method of developing System Requirements started with discussing the present process with Authors and Law Reviews and determining current needs of the users. Afterwards, a comparison among competitors was discussed to generate limitations of these systems and determine features to emulate for the development of ALRSS. Thirdly, a workflow model was created to examine internal issues of submission tracking and management within the Law Review to further automate the review process and make management of the process more effective. As a result, a more efficient and effective submission process is feasible for both the Author and Law Review by allowing processes to occur electronically from the Author submitting a manuscript to a Law Review Editor assigning or viewing a manuscript. In addition, with electronic tracking, time consuming communication regarding the submission status between the parties can be minimized. This submission system can be further customized for improved features or broader purposes in the future.

Full textAbstract:
In a web application, “webform” plays an important role in providing interactions between users and a server. To develop a webform in conventional method, developers have to create many files including HTML-JavaScript, SQL script, and many server-side programs to process to data. In this thesis, we propose a new language, Webform Language (WFL). WFL can considerably decrease developing time of webform by describing it in XML and a parser will automatically generate all necessary files. In addition, we give an option for user to describe a webform in another language, called Simple Webform Language (SWFL). The syntax of a SWFL is simple and similar to the “CREATE TABLE” statement in SQL. When a parser parse webform description in SWFL, it translated the description to WFL first, and then processed it by as normal WFL.

Full textAbstract:
[Truncated abstract] The development of an automated classification system of wear particles or surfaces is of great interest to the machine condition monitoring industry. The system, once developed, may also find applications in medical diagnostics. Such a tool will be able to replace human experts in the detection of the onset of early machine failure, or in the diagnosis and prognosis of, for example, joint diseases. This will improve efficiency, reliability and also reduce costs of monitoring or diagnostic systems. Current literature available on this topic has included various studies on different classification methods. However, there has been no work conducted on the development of a totally integrated automated classification system. The first part of this thesis presents a study investigating the efficiency and robustness of various pattern recognition methods currently described in literature. A special computer program was developed to test each of the classification methods against both standard image databases and tribological surface images. There are three core components of a pattern recognition system that need to be analysed: (1) feature extraction, (2) feature reduction and (3) classifier. Each of these components provides a vital link that can affect the reliability of the complete classification system. ... The optimal classifier was the Linear Support Vector Classifier. This part of research is described in Paper 2. The second part of this thesis contains work verifying the performance of the automated classification system developed using both tribological and bio-tribological surface images. Experiments were carried out to generate wear particles created under different wear mechanisms (adhesive, abrasive and fatigue wear) and various operating conditions representing different degree of wear severity. The automated classification system developed was able to successfully classify wear particles with respect to both the type of wear mechanism operating and the wear severity. The results of this classification are described in Papers 3 and 5. The success of the automated classification system was also confirmed by its ability to classify different groups of worn (osteoarthritic) cartilage surfaces (Paper 4). This could lead to potential applications of the system for early detection of the onset of osteoarthritis. In conclusion, the automated classification system developed can accurately classify both tribological and bio-tribological surface images. This system could become a vitally important tool in both machine condition monitoring and medical diagnostics.

This thesis describes WebDoc, an automated system that classifies Web documents according to the Library of Congress classification system. This work is an extension of an early version of the system that successfully generated indexes for journal articles. The unique features of Web documents, as well as how they will affect the design of a classification system, are discussed. We argue that full-text analysis of Web documents is inevitable, and contextual information must be used to assist the classification. The architecture of the WebDoc system is presented. We performed experiments on it with and without the assistance of contextual information. The results show that contextual information improved the system?s performance significantly.

Texas Instruments is the world leader in digital signal processing and analog technologies. In order to showcase two new products (the ADS1220 and DAC8760), the company created a project to cool and dispense beer automatically. The ability to successfully display the accuracy and precision of their new technologies is key in the design and manufacture of loop powered sensor field transmitters, utilizing high precision data converter integrated circuits. These transmitters are used to monitor temperatures at different locations within the beer cooling system through the use of Resistance Temperature Device (RTD) sensors. The sensors, along with other industrial instrumentation, interface with a Programmable Logic Controller (PLC) to dispense beer at the appropriate temperature and fill a receptacle to the desired level. The water, cooled by the Thermal-Electric Coolers (TECs), is re-circulated through a water bath that houses the beer coil and absorbs the heat dissipated by the beer at a rate of 37°F/hr. Additionally, system status and settings can be seen and changed by a user through an iPad GUI application. This temperature control application highlights TI’s accurate and precise technologies for designers in the process control industry.

Full textAbstract:
Developing training scenarios that induce a trainee to utilize specific skills is one of the facets of simulation-based training that requires significant effort. Simulation-based training systems have become more complex in recent years. Because of this added complexity, the amount of effort required to generate and maintain training scenarios has increased. This thesis describes an investigation into automating the scenario generation process. The Automated Scenario Generation System (ASGS) generates expected action flow as contexts in chronological order from several events and tasks with estimated time for the entire training mission. When the training objectives and conditions are defined, the ASGS will automatically generate a scenario, with some randomization to ensure no two equivalent scenarios are identical. This makes it possible to train different groups of trainees sequentially who may have the same level or training objectives without using a single scenario repeatedly. The thesis describes the prototype ASGS and the evaluation results are described and discussed. SVSTM Desktop is used as the development infrastructure for ASGS as prototype training system.M.S.Cp.E.

Full textAbstract:
Critical Infrastructures play a central role in the world around us and are the backbone of everyday life. Their service provision has become more widespread, to the point where it is now practically ubiquitous in many societies. Critical Infrastructure assets contribute to the economy and society as a whole. Their impact on the security, economy and health sector are extremely vital. Critical Infrastructures now possess levels of automation that require the integration of, often, mutually incompatible technologies. Their increasing complexity has led to the creation of direct and indirect interdependent connections amongst the infrastructure groupings. In addition, the data generated is vast as the intricate level of interdependency between infrastructures has grown. Since Critical Infrastructures are the backbone of everyday life, their protection from cyber-threats is an increasingly pressing issue for governments and private industries. Any failures, caused by cyber-attacks, have the ability to spread through interconnected systems and are a challenge to detect; especially as the Internet is now heavily reliant on Critical Infrastructures. This has led to different security threats facing interconnected security systems. Understanding the complexity of Critical Infrastructure interdependencies, how to take advantage of it in order to minimize the cascading problem, enables the prediction of potential problems before they happen. Therefore, this work firstly discusses the interdependency challenges facing Critical Infrastructures; and how it can be used to create a support network against cyber-attacks. In much, the same way as the human immune system is able to respond to intrusion. Next, the development of a distributed support system is presented. The system employs behaviour analysis techniques to support interconnected infrastructures and distribute security advice throughout a distributed system of systems. The approach put forward is tested through a statistical analysis methodology, in order to investigate the cascading failure effect whilst taking into account the independent variables. Moreover, our proposed system is able to detect cyber-attacks and share the knowledge with interconnected partners to create an immune system network. The development of the ‘Critical Infrastructure Auto-Immune Response System’ (CIAIRS) is presented with a detailed discussion on the main segments that comprise the framework and illustrates the functioning of the system. A semi-structured interview helped to demonstrate our approach by using a realistic simulation to construct data and evaluate the system output.

This thesis investigates the possibility to automate testing of PCBs with a sensor system. This PCB testing is today done manually by placing PCBs in a test fixture that determines its condition. This test requires an operator to wait for the test to complete and then place the PCB in the correct section. If this process can be automated time could be saved and the risk of mishandling PCBs could be reduced. A sensors system is made that consists of an Arduino with micro switches, hall effect sensors, a scanner and a LiDAR. The sensor system is designed to achieve a set of requirements that is needed for automation. The sensor system is meant to communicate with a robot that moves the PCBs within a test environment. This test environment is also designed in this project. For the system to communicate with a robot a program is made to inform the robot about placement of PCBs within the test environment. The final system is able to achieve the requirements set for automation but further investigation is needed to make this into a fully scaled automated system.

Full textAbstract:
Supervisory control and data acquisition (SCADA) is a computer system for analysing, and monitoring data, as well as, controlling a plant in industries such as power grids, oil, gas refining, and water control. SCADA belongs to the category of critical systems that are needed to maintain the infrastructure of cities and households. Therefore, the security aspect of such a system has a significant role. The early SCADA systems were designed with the operation as the primary concern rather than security since they were a monolithic networked system without external access. However, the systems evolved, and SCADA systems were embedded with web technologies for users to monitor the data externally. These changes improved the efficiency of monitoring and productivity; however, this caused a problem of potential cyber-attacks to a SCADA system. One such example was Ukraine’s power grid blackout in 2015. Therefore, it is beneficial for the security of a SCADA system to create a threat modeling technique that can understand the critical components of SCADA, discover potential threats, and propose possible mitigation strategies. One issue when creating a threat model is the significant difference of SCADA from traditional Operational Technology (OT) systems. Another significant issue is that SCADA is a highly customisable system, and each SCADA instance can have different components. Therefore, for this work, we implemented a threat modeling language scadaLang, which is specific to the domain of a SCADA system. We started by defining the major assets of a SCADA system, attackers, entry surfaces, and built attacks and defense strategies. Then we developed a threat modeling domain-specific language scadaLang that can create a threat model for a particular instance of SCADA taking the differences in components and connections into account. As a result, we achieved a threat modeling language for SCADA, ensured the reliability of the results by peer-reviewing of an engineer familiar with the domain of the problem, and proposed a Turing test to ensure the validity of the result of scadaLang as the future development of the project.Supervisory control and data acquisition (SCADA) är ett datorsystem för att analysera och monitorera data samt kontrollera anläggningar för industrier såsom energisystem, olja, raffinering av gas och vatten. SCADA tillhör den kategori av kritiska system som krävs för att bibehålla städer och hushålls infrastruktur. Därför är säkerhetsaspekten av ett sådant system av stor roll. De tidiga SCADA systemen var utformade med funktionen som huvudsaklig oro istället för säkerheten då de var monolitiska nätverkssystem utan extern åtkomst. Systemen utvecklades emellertid och SCADA systemen blev inbyggda med webbteknologier så att användare kan monitorera data externt. De här förändringarna förbättrade effektiviteten av monitorering och produktivitet men skapade problemet med potentiella cyber-attacker mot SCADA systemen. Ett sådant exempel är Ukrainas energy systems elavbrott som skedde 2015. Därför är det fördelaktigt för säkerheten av SCADA systemen att skapa en hotmodelleringsteknik för att bättre förstå de kritiska komponenterna av SCADA, hitta potentiella hot och föreslå potentiella förmildrande strategier. Ett problem för utvecklingen av en hotmodell är den stora skillnaden mellan SCADA från traditionella nätverkssystem inom industri. Ett annat stort problem är att SCADA är ett justerbart system och varje SCADA instans kan ha olika komponenter. Därför utvecklar vi i detta arbete ett språk för hotmodellering scadaLang som är specifikt för domänen SCADA system. Vi började med att definiera de huvudsakliga komponenterna av SCADA system, angriparna, attack ytorna och även bygga attacker samt försvarsstrategier. Sen utvecklade vi ett språk för hotmodelleringen som är domänspecifikt, scadaLang som kan skapa en hotmodell för en specifik instans av SCADA där skillnaderna på komponenter och sammankopplingar tas till hänsyn. Som resultat har vi skapat ett språk för hotmodellering för SCADA,verifierat resultat med hjälp av en ingenjör med domänkännedom och föreslagit ett Turing test för att förbättra verifieringen av resultatet som ett framtida arbete.

Full textAbstract:
Many important modern engineering problems involve satisfying multiple objectives. Simultaneous optimization of these objectives can be difficult as they compete for the same set of any given resources. One way to solve multiple-objective optimization is with the use of genetic algorithms (GA’s).
One can break down the structure of these multi-objective genetic algorithms (MOGA’s) into two different approaches. One approach is based on incorporating multiple objectives into a single fitness function which will evaluate how well a given solution solves the issue. The other approach uses multiple fitness functions, each representing a different objective, which when combined create a solution set of possible solutions to the problem. This project focuses on combining these approaches in order to make a hybrid model, which can benefit from combining the results of the previous two methods; incorporating a level of automation that allows for inference of a final solution based on different prioritization of each objective. This solution would not have been previously attainable by either standalone method.
This project is named the Automated Inferential Multi-Objective Optimization System (AIMOS), and it can be applied to a multitude of different problem types. In order to show its capabilities, AIMOS has been applied to a theoretical optimization problem used to measure the effectiveness of GA’s.

Approved for public release; distribution is unlimitedInfluencing one's adversary has always been an objective in warfare. However, to date the majority of influence operations have been geared toward the masses or to very small numbers of individuals. Although marginally effective, this approach is inadequate with respect to larger numbers of high value targets and to specific subsets of the population. Limited human resources have prevented a more tailored approach, which would focus on segmentation, because individual targeting demands significant time from psychological analysts. This research examined whether or not Information Technology (IT) tools, specializing in text mining, are robust enough to automate the categorization/segmentation of individual profiles for the purpose of psychological operations (PSYOP). Research indicated that only a handful of software applications claimed to provide adequate functionality to perform these tasks. Text mining via neural networks was determined to be the best approach given the constraints of the profile data and the desired output. Five software applications were tested and evaluated for their ability to reproduce the results of a social psychologist. Through statistical analysis, it was concluded that the tested applications are not currently mature enough to produce accurate results that would enable automated segmentation of individual profiles based on supervised linguistic processing.

Full textAbstract:
E-Park is an electronic parking meter system which enables real-time ticketing of illegally parked vehicles. The system is a drop-in replacement for existing curb-side parking meters. It consists of lowpower front-end parking meter hardware and a back-end server that handles the information database management. Wireless network communication enables the parking meter to accept electronic payment, enforce parking regulation, and ticket parking violators by capturing an image of the vehicle license plate. The image is sent to the central server where the license plate number is automatically extracted from the image using an Automated License Plate Recognition (ALPR) algorithm. The meter includes a visual feedback system which tells the driver how to optimally position the vehicle relative to the parking meter. This is done in order to ensure that any images captured by the camera contain a good view of the vehicle license plate. The system relies on solar rechargeable batteries so that it may function completely untethered and without the need for human intervention.
Field tests of the system proved that the visual driver feedback successfully allowed 5 different drivers to consistently position their vehicles at the correct distance relative to the meter. Testing of the OpenALPR algorithm utilized to automatically extract license plate information from the images showed that the relative angle with which the camera views the license plate can be no larger than 55°. Although this presents some limitations, the proposed parking meter architecture introduces redundancies that successfully circumvent this limitation and can ensure that the system achieves ticketing rates upwards of 90% of vehicles.Electrical Engineering
