Full textAbstract:
Webcam (Web Camera) is a designation for real-time cameras (meaning the current situation) whose images can be accessed or viewed through the World Wide Web, instant messaging programs, or video call applications. During this time, the webcam application is only used to record and display objects, but has never been used for other applications such as security applications that are used to detect object movements. Webcams can not provide information about the motion of an object, passive or active objects. Therefore, research to improve the system to be able to detect motion from images captured from this webcam needs to be done.The motion detection system of an object works if the captured object has a changed position, and will automatically activate an alarm. The image processing method used in motion detection is the edge detection method, while for the motion detection process, the pixel position comparison process is used.

AbstractFinancial problems cannot be separated from mathematics with calculations. Likewise in Financial Mathematics which discusses the annuity of a loan that takes into account the loan interest with a repayment period for a certain period. Many applications have been built by loan providers (creditors) to make it easier for borrowers (debtors) to simulate these loans. Applications made are web-based and desktop-based. One of application that can be used to create loan repayment applications (annuities) is Microsoft Visual Basic. By using Microsoft Visual Basic, you can build a loan repayment application that calculates the interest and length of repayment, which is combined with Microsoft Access as the database and Crystal Report to create the report. In addition to storing debtor data, the application also makes it easier for debtors to simulate loans and find out the amount of annuity they will pay.

In the modern world of technologies (sciences of arts), optimum operation time is the prime consideration. Technologies with greater operation time are needed to be modified or replaced as per the requirement of the current scenario. In small and medium enterprises of developing countries, almost all the reporting activities are conducted in Microsoft Excel. The manual operation in Microsoft Excel takes a long time (17.37 minutes, only if there was one order of only one article with one color) of the users; furthermore, there can also be a greater chance of error in the report. In the same way, the order costing report at the ABC footwear company of Lahore is prepared manually in Microsoft Excel which used to take a long time to be prepared along with the greater probability of errors in the report. Because of the above-mentioned reasons, the order costing report was decided to be automated with the help of visual basic for applications (VBA) in Microsoft Excel. The manual procedure including all the activities was collected from the planning and costing department of ABC Company. Moreover, all the activities were listed down and their time study was conducted. VBA macros were programmed with the objectives of automating all the manual tasks of the order costing report in Microsoft Excel and eliminating the chance of error (calculation error made by the employee). Macros, were programmed by the use of conditional statements, (i.e. if and else conditions) and various types of loops, (i.e. Do while loop and for loop). Automated decisions were made with the help of conditional statements during the operation and the conditional statements were circulated with the help of loops across the whole worksheet. Two userforms were designed for the execution of macros by the click of command buttons (having macros at their back). Total eight worksheets were incorporated into the automated template. All the programmed VBA macros were explained with the help of flowcharts made in the Microsoft Visio. After the report was automated, a time study of operations performed after each click was conducted with the help of stop watch. The data obtained by the time study was entered into Microsoft Excel so that the time of old and suggested methods could be compared. Comparison of both methods indicated that the suggested method took 85.92% less time as compared to the old method of preparing the order costing report. At the same time, the report made by the suggested method was free of errors and the workload of employees was also reduced.

Full textAbstract:
This thesis investigates problems in hierarchical games. Mathematical models are
used in tennis to determine when players should alter their effort in a game, set
or match to optimize their available energy resources. By representing warfare,
as a hierarchical scoring system, the results obtained in tennis are used to solve
defence strategy problems. Forecasting in tennis is also considered in this thesis.
A computer program is written in Visual Basic for Applications (VBA), to estimate
the probabilities of players winning for a match in progress. A Bayesian
updating rule is formulated to update the initial estimates with the actual match
statistics as the match is progressing. It is shown how the whole process can
be implemented in real-time. The estimates would provide commentators and
spectators with an objective view on who is likely to win the match. Forecasting
in tennis has applications to gambling and it is demonstrated how mathematical
models can assist both punters and bookmakers. Investigation is carried out on
how the court surface affects a player�s performance. Results indicate that each
player is best suited to a particular surface, and how a player performs on a
surface is directly related to the court speed of the surfaces. Recursion formulas
and generating functions are used for the modelling techniques. Backward recursion
formulas are used to calculate conditional probabilities and mean lengths
remaining with the associated variance for points within a game, games within
a set and sets within a match. Forward recursion formulas are used to calculate
the probabilities of reaching score lines for points within a game, games within
a set and sets within a match. Generating functions are used to calculate the
parameters of distributions of the number of points, games and sets in a match.

Pour répondre aux attentes de clients de plus en plus exigeants, les entreprises d'aujourd'hui doivent accroître leur compétitivité, leur productivité et leur réactivité. Pour répondre à ces exigences, la fonction ordonnancement se doit d'être plus réactive, plus performante et plus adaptée aux spécificités des compagnies. Parmi les différentes possibilités d'évolution de l'ordonnancement, la voie de l'ordonnancement interactif semble répondre à ces besoins, et parmi les approches possibles de l'interactivité, l'utilisation d'indicateurs permet au gestionnaire d'atelier de connaître toutes les données nécessaires à la mise au point d'un ordonnancement performant. Quatre types d'indicateurs ont été définis : - des indicateurs de contexte décrivant l'état général de l'atelier, - des indicateurs de diagnostic aidant à identifier les causes de problèmes courants, - des indicateurs d'action renseignant sur la pertinence et l'efficacité de l'utilisation des degrés de liberté, - des indicateurs de performance, évaluant les performances de l'ordonnancement par rapport aux objectifs de l'entreprise. Cette approche de l'ordonnancement interactif a été appliquée à deux problématiques actuelles. Des indicateurs spécifiques à ces deux problèmes ont été définis. La première application concerne la prise en compte dans l'ordonnancement de commandes incertaines, encore en cours de négociation. La deuxième application concerne la gestion des opérateurs de production à court terme, au niveau de l'ordonnancement. Un outil de construction de tableaux de bord mettant en oeuvre ces différents indicateurs a été réalisé dans le cadre d'un projet européen (le projet ASPIRE).

Human disturbance as the main factor influencing the habitat of brown bear (Ursus arctos) has occurred frequently with the development of human society. How to reduce and prevent the conflict between human and brown bears is considered as an important question for brown bear conservation, management and public safety. Sånfjället National Park has one of the densest bear populations in Sweden. Many tourists are attracted to visit bears each year. Through this study, the most possibility brown bear denning habitat in Sånfjället National Park was determined by using Multi-Criteria Analysis. A customized habitat distribution map generator was programmed within the Microsoft Visual Basic® for Applications (VBA) in ArcGIS. Three themes were designed in the map generator, i.e., the human impact emphasis weighted, neutral weighted themes and customized weighted theme. Customized weighted theme was produced for user discovering denning habitat results with user-defined weights. Comparing the final maps generated from the human impact emphasis weighted and neutral weighted themes, human influence concentrated in the south area of the National Park. The trails near Sveduterget should be changed to avoid human disturbance in the bear denning period.

Marco, Pontus. "Design & optimization of modular tanksystems for vehicle wash facilities." Thesis, Karlstads universitet, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:kau:diva-79009.
Full textAbstract:
Clean and safe water is important for the well being of all organisms on earth. Therefore, it is important to reduce harmful emissions from industrial processes that use water in different ways. In vehicle washing processes, water is used in high-pressure processes, as a medium for detergents, and for rinsing of vehicles. The wastewater produced by these functions passes through a water reclamation system. A water reclamation system has two main functions, to produce reusable water to be used in future washing cycles, and to separate contaminants and purify the wastewater so it can be released back into the commercial grid. The reclamation system achieves this by using a combination of different water handling processes, these include: sludge tanks, an oil-water separator, a water reclamation unit, buffer tanks, and a water purification unit. The two components that stand for the more advanced cleaning processes are the water reclamation unit and the water purification unit. In this thesis, in collaboration with the company Westmatic, the water reclamation unit consists of cyclone separators that use centrifugal forces to separate heavy particles and ozone treatment to break up organic substances and combat bad odors. The Purification unit of choice is an electrocoagulation unit that, by a direct current, creates flocculants of impurities that rises to the surface and can be mechanically removed in a water volume inside the unit. This purification process is completely chemical-free thus making the process more environmentally friendly than other purification processes used in other circumstances. This master thesis aimed to develop a dynamic design tool for a modular solution of the different parts in the water reclamation system. This design tool uses specific user input to produce construction information for each instance. As an additional sub-aim, this design tool was linked with a computer-aided design program to produce parametric 3D models with underlying blueprints. This to produce a light solution, that has a short manufacturing time and that are highly customer adjusted. The first course of action was to mathematically define the complete water reclamation system and its components. These sections were described in a flowchart that shows how the different parts interact and operate. From the wash station, wastewater runs trough a course- and fine-sludge tank. From the fine sludge tank, the wastewater is directed in two different directions. Firstly, the water is pumped to the water reclamation unit and to one or multiple buffer tanks to finally be used in the wash station as reclaimed water. Secondly, the water travels to an oil separator, pump chamber, and water purification unit. In the purification unit, 99% of the inlet mass is directed out of the system as purified water. The remaining 1% is directed to a depot that acts like the end stage of the whole system. After all equations were defined and the design was related to the user-defined input flow the design tool was structured. The program of choice to house the design tool is Microsoft Excel. In this Excel document, a user interface with navigation was constructed and the intended user is directed through a series of input pages where input data is defined. This data is used in a normally hidden page where constructional dimensions are calculated. The constructional dimensions are displayed to the user on the second last page. At this stage the Excel document can be connected to a CAD program and 3D models with blueprints can be opened that depend on the output from the Excel file. Additionally, a pipe calculator is provided on the last page of the Excel document where pipe dimensions for different cases can be found. With this solution, glass fiber tanks are molded according to the resulting blueprints that are customer specific. In this way the solution is more adaptive and easier to handle. Additionally, the provided design tool enables an easier and more well-defined methodology when deriving the different needed volume and accompanied constructional dimensions for an arbitrary water reclamation system.

Alileche, Nassim. "Etude des effets dominos sur une zone industrielle." Thesis, Rouen, INSA, 2015. http://www.theses.fr/2015ISAM0013.
Full textAbstract:
Les effets dominos ou cascade d’événements dans les industries et particulièrement dans les industries chimiques et de transformation, sont reconnus comme des scénarios d’accidents possibles depuis environ trois décennies. Ils représentent une préoccupation croissante, car ils ont le potentiel de provoquer des conséquences dévastatrices. L’effet domino, comme phénomène, est un sujet controversé lorsque son évaluation est nécessaire. L’examen de la bibliographie a démontré l’absence d’une définition commune et d’une procédure simple d’utilisation et précise pour son appréciation. C’est pourquoi l’un des objectifs de cette recherche est de formaliser les connaissances relatives aux effets dominos afin de comprendre les mécanismes de leurs occurrences. Pour ce faire nous avons étudié les paramètres à examiner pour déterminer la possibilité de cascade et être en mesure d’identifier les scénarios dominos. L’enjeu étant de permettre l’amélioration de la prévention du risque d’effet domino. L’autre objectif est donc de produire une méthode pour l’identification et l’analyse des effets dominos. Nous avons développé une méthodologie globale pour l’étude des effets dominos en chaîne initiés par des pertes de confinement. Elle permet l’identification et la hiérarchisation des chemins de propagation des accidents. Cette méthode facilite la prise de décision pour la prévention des effets dominos, tout en proposant un outil efficace et simple d’utilisation. Les résultats de l’étude sont fournis sous forme d’une hiérarchisation quantitative des équipements impliqués dans les scénarios dominos, en tenant compte des effets des conditions météorologiques et des mesures de maîtrise des risques existantes ou proposées.Cette hiérarchisation donne une idée claire des dangers que représentent les équipements par rapport aux accidents en cascade, en précisant si la dangerosité de l’équipement provient de sa capacité à initier ou à propager un effet de cascade.La méthode est basée sur une description topographique de la zone étudiée, incluant les caractéristiques de chaque équipement, et prend en compte les mesures de maîtrise des risques mises en œuvre par l’industriel. Elle repose sur deux phases principales : La première, est l’identification des chemins de propagation des accidents. Pour ce faire, la méthode d’analyse par arbre d’événements est utilisée. Les cibles potentielles sont déterminées en combinant les valeurs seuils d’escalade et les modèles de vulnérabilité (pour l’estimation de la probabilité d’endommagement). Cette première phase est implémentée sous MATLAB® et Visual Basic for Applications (VBA) afin de faciliter l’entrée des données, et l’analyse des résultats dans Microsoft Excel®. La deuxième phase est l’identification des équipements les plus dangereux vis-à-vis des effets dominos. Elle consiste à hiérarchiser les équipements impliqués dans les chemins de propagation, en fonction de leur vraisemblance à causer ou à propager un effet domino. L’algorithme qui effectue cette phase est codé sous VBA. La méthode a été conçue de façon à ce qu’elle puisse être utilisée sans qu’il soit nécessaire de s’appuyer sur les résultats des études de dangers. Néanmoins, si ces résultats sont disponibles, il est alors possible d’alléger certaines étapes de la méthode. Elle s’est révélée facile à utiliser, cela a été constaté lors de son application dans le cadre de projets et stages d’étudiantsDomino effects or cascading events in the chemical and process industries are recognized as credible accident scenarios since three decades. They are raising a growing concern, as they have the potential to cause catastrophic consequences. Domino effect, as phenomenon, is still a controversial topic when coming to its assessment. There is still a poor agreement on the definition of domino effect and its assessment procedures. A number of different definitions and approaches are proposed in technical standards and in the scientific literature. Therefore, one of this research objectives is to formalize domino effects knowledges in order to comprehend their occurrence mechanisms. Thus, the parameters that should be looked at so as to understand the escalation possibility and in order to identify domino scenarios, were analyzed. The aim is to improve domino effect hazards prevention, through the development of a methodology for the identification and the analysis of domino effects.We developed a method for the analysis of domino accident chain caused by loss of containments. It allow the identification and prioritization of accident propagation paths. The method is user-friendly and help decision making regarding the prevention of cascading events. The final outcomes of the model are given in form of quantitative rankings of equipment involved in domino scenarios, taking into account the effect of meteorological conditions and safety barriers. The rankings give a clear idea of equipment hazard for initiating or continuing cascading events.The methodology is based on a topography of the industrial area of concern, including the characteristics of each unit and accounting for protection and mitigation barriers. It is based on two main stages. The first is the identification of accident propagation paths. For this, the event tree method is used. The possible targets are identified combining the escalation thresholds and vulnerability models (to estimate damage probability). This first stage was implemented using the MATLAB® software and Visual Basic for Applications (VBA) to enable an easy input procedure and output analysis in Microsoft Excel®.The second stage is the identification of the most dangerous equipment. It consists in prioritizing equipment involved in the propagation paths according to their likelihood to cause/propagate domino effect. The algorithm that performs this phase was coded in VBA.The method was designed so as it can be used without the need to rely on the results of safety reports. However, if such results are available, it is possible to lighten some steps of the method. It revealed easy to apply, this was confirmed through projects and student internships
Gli effetti domino, in cui un primo incidente causa in cascata altri scenari incidentali, sono tragli scenari incidentali più severi che avvengono nell’industria chimica. Nonostante l’attenzioneche anche la normativa dedica a tali scenari, la valutazione dell’effetto domino è un soggettocontroverso. L’analisi della letteratura tecnica e scientifica ha mostrato l’assenza di unadefinizione comune di « effetto domino » e di una semplice procedura per l’identificazione ditali scenari. È per tale motivo che uno degli obiettivi di questo lavoro di ricerca è diformalizzare le conoscenze relative agli effetti domino al fine di meglio comprendere imeccanismi che possono provocarli. A tal proposito sono stati studiati i parametri necessariper determinare la possibilità dell’insorgere di cascate di eventi e per essere in grado diidentificare i possibili scenari incidentali dovuti ad effetto domino. L’obiettivo finale del lavoroè stato di sviluppare un metodo per l’identificazione e l’analisi quantitativa della propagazionedi incidenti primari nell’ambito di scenari dovuti ad effetto domino.E’ stata sviluppata una metodologia generale per l’analisi degli effetti domino causati daperdite di confinamento. Tale metodologia permette l’identificazione e la classificazione deipercorsi di propagazione degli incidenti. Tale metodo facilita inoltre la prevenzione deglieffetti domino, proponendo uno strumento efficace e semplice da utilizzare.I risultati di questo studio sono forniti in forma di una classificazione delle apparecchiaturecoinvolte in scenari dovuti ad effetto domino, tenendo conto degli effetti delle condizionimeteorologiche e delle misure esistenti per la gestione del rischio. Tale classificazione fornisceanche un chiara idea dei pericoli rappresentati dalle singole apparecchiature nel caso diincidenti in cascata, in quanto precisando se la pericolosità delle attrezzature proviene dallaloro capacità di innescare o propagare un reazione a catena.Il metodo è basato su una descrizione topografica del sito studiato, che comprende anche lecaratteristiche di ogni attrezzatura, che tiene conto delle misure di gestione dei rischi e dellebarriere di sicurezza presenti, basato su due fasi principali. La prima è l’identificazione deipercorsi di propagazione degli incidenti. A tale scopo è stato utilizzato un metodo basatoVIsull’albero degli eventi. I potenziali bersagli vengono determinati combinando i valori di sogliaper la propagazione degli eventi ed i modelli di vulnerabilità delle apparecchiature. Questaprima fase è implementata in MATLAB® e Visual Basic for Applications (VBA) in modo dafacilitare la gestione dei dati e l’analisi dei risultati in Microsoft Excel®.La seconda fase è l’identificazione delle apparecchiature più pericolose per gli effetti domino.Tale fase consiste nel classificare le apparecchiature coinvolte nei percorsi di propagazione infunzione della loro capacità di causare o propagare un effetto domino. L’algoritmo dedicato inquesta fase è eseguito su VBA.I risultati ottenuti anche nell’applicazione ad un caso di studio hanno evidenziato le potenzialitàdel metodo, che rappresenta un significativo progresso nell’analisi quantitativa dell’effetto domino

Full textAbstract:
Object detection and filtering based on shape and color is an important capability for many robotics applications. For example, sorting objects by shape and color is a common industrial application. Service robots also need to detect and track objects based on visual properties. While powerful deep learning approaches like YOLO have emerged for general object detection, they require large datasets and extensive training. A simple shape and color filtering provide a lightweight and customizable alternative. This work aims to provide a real-time modular and lightweight system that can identify objects of basic shapes and colors and allow extensibility of functionality by incorporating more custom color and shape filters. The proposed system for real-time shape and color filtering using a Microsoft Kinect RGB-D sensor and Robot Operating System (ROS2) can identify an array of regular shapes like circles, rectangles, and triangles over a spectrum of different colors. New shape and color filters can be added dynamically at runtime thanks to the modular, ROS-2-based implementation.

This paper presents an easy-to-use spreadsheet module in Microsoft Excel to handle the implementation of the ANSI standards for tolerance fits for shafts and collars. The module makes use of drop-down menus and an embedded Visual Basic numerical algorithm to locate the correct tolerance ranges for a shaft and collar combination for the entire range of tolerances handled by the tables published in the ANSI standard. This module allows the quick implementation of designs and features a process that is less subject to errors associated with the traditional method of reading of the tolerance tables and transferring this information manually. The method is particularly helpful to students and inexperienced designers who first encounter the need to utilize tolerances in engineering designs. The paper presents an example application to illustrate the overall utility of the module.

In NCSL International Workshop & Symposium. NCSL International, 2018. http://dx.doi.org/10.51843/wsproceedings.2018.14.
Full textAbstract:
The GUM Supplement 2 deals with measurement models with more than one output quantities, which may be mutually correlated. Such measurement models are common in electrical metrology where the measurand can be complex-valued quantities, such as S-parameters. The GUM Supplement 2 describes a Monte Carlo Method (MCM) for evaluating the output quantities, their standard uncertainties, the covariances between them and the coverage region. The Standards and Calibration Laboratory (SCL) has developed six years ago a software tool for evaluation of measurement models for complex-valued quantities in accordance with GUM Supplement 2. The SCL software tool was written in Visual C++ and Visual Basic for Application (VBA), with Microsoft Excel as frontend user interface. As MCM involves large number of repetitive computations, this old SCL software tool has long processing time especially for complicated measurement models such as coaxial airline. Nowadays many personal computers are equipped with Graphics Processing Unit (GPU) containing massive number of floating point cores. A high end GPU may have nearly 2000 cores while the main CPU normally has only up to 4 cores. As MCM is well suited to parallel processing, to speed up the uncertainty computation, SCL has ported the algorithm to GPU using the Open Computing Language (OpenCL) which was specially designed to support parallel computing. The new SCL tool is an add-on module to Microsoft Excel which allows uncertainty budget listed in spreadsheet table to be calculated by MCM. GPU from the major suppliers Nvidia, AMD and Intel are supported. The uncertainty computation time can be reduced by more than ten times. This paper describes the design and implementation of this new software tool.

Full textAbstract:
Worldwide interest in using recycled materials in flexible pavements as an alternative to virgin materials has increased significantly over the past few decades. Therefore, recycling has been utilized in pavement maintenance and rehabilitation activities. Three types of in-place recycling technologies have been introduced since the late 70s: hot in-place recycling, cold in-place recycling, and full-depth reclamation. The main objectives of this project are to develop a framework and a life-cycle assessment (LCA) methodology to evaluate maintenance and rehabilitation treatments, specifically in-place recycling and conventional paving methods, and develop a LCA tool utilizing Visual Basic for Applications (VBA) to help local and state highway agencies evaluate environmental benefits and tradeoffs of in-place recycling techniques as compared to conventional rehabilitation methods at each life-cycle stage from the material extraction to the end of life. The ultimate outcome of this study is the development of a framework and a user-friendly LCA tool that assesses the environmental impact of a wide range of pavement treatments, including in-place recycling, conventional methods, and surface treatments. The developed tool provides pavement industry practitioners, consultants, and agencies the opportunity to complement their projects’ economic and social assessment with the environmental impacts quantification. In addition, the tool presents the main factors that impact produced emissions and energy consumed at every stage of the pavement life cycle due to treatments. The tool provides detailed information such as fuel usage analysis of in-place recycling based on field data.

Full textAbstract:
Welds made onto in-service pipelines tend to cool at an accelerated rate as the result of the flowing content"s ability to remove heat from the pipe wall. These welds are therefore likely to have high heat-affected zone (HAZ) hardness values and to be susceptible to hydrogen cracking. The use of thermal analysis modeling allows welding parameters (i.e., required heat input levels) to be selected based on anticipated weld cooling rates. Both the Battelle model and the recently developed PRCI Thermal Analysis Model for Hot Tap Welding assume that the pipe material is the most susceptible material being welded. Some attachments (e.g., hot formed fittings, etc.) have a significantly less favorable chemical composition (i.e., higher carbon equivalent level) than the pipe material. As a result, for some in-service welding applications, the attachment material may be more susceptible to cracking than the pipe material. Modifications were made to the finite-element solver of the PRCI model to enable hardness prediction in both the pipe and attachment material. The source code for the modified finite-element solver was provided to Technical Toolboxes - PRCI"s commercial partner for software marketing and distribution. The required modifications to the user interface were also developed. In addition, user interface modifications required to rectify a number of faults that were identified and to improve the user interface were also developed. The incorporation of these enhancements and improvements, which are described herein, will require modification by Technical Toolboxes of the Visual Basic-based version of the software that is currently being marketed (V4.2.1). Following the incorporation of these enhancements and improvements, validation trials should be carried out.
