El sistema Bus Rapid Transit (BRT) es uno de los modos de transporte más demandados en los últimos años. Este sistema de transporte cuenta con estaciones para los usuarios y múltiples líneas de buses en una determinada ciudad. Sin embargo, el desorden en el recorrido de los usuarios a lo largo de la estación y la alta densidad e interacción peatonal generan largos tiempos de espera para los usuarios desde que entran a la estación hasta su embarco al bus. La presente investigación propone una gestión de la movilidad peatonal, la cual mediante la canalización de flujos peatonales y adaptación de entradas y salidas de la estación tiene por objetivo principal reducir los tiempos de espera de los usuarios dentro de la estación. Se realizó visitas a una estación de BRT en la ciudad de Lima para medir los tiempos de espera de los usuarios dentro de esta. La recolección de información nos permitió establecer el horario de más concurrencia peatonal y demostrar que los usuarios pueden demorar más tiempo dentro de la estación que en el bus. La propuesta fue simulada en el software Vissim para poder determinar su eficiencia. Los resultados muestran que se redujo los tiempos de espera de los usuarios dentro de la estación en un 25%. Por otro lado, el valor de la densidad peatonal y los puntos de conflicto entre peatones disminuyeron en un 44% y 73% respectivamente. Finalmente se obtuvo un aumento en la velocidad peatonal de los corredores en un 37%. / The Bus Rapid Transit (BRT) is a bus-based public transport system that increase the effectiveness of public transportation through dedicated lanes with busways and independent stations. However, the pedestrian routes disorder at the station, the high density and the interaction between pedestrians produce high waiting times since the entrance at the station until the board at the bus. The present research proposes a management of pedestrian mobility focused on modify the pedestrian routes and adapting the entrance and exit of the station. The main objective of the investigation is reducing the waiting times of users at the station. Users waiting times at the station were measured by visiting a BRT station located in the city of Lima. The collection of information makes it possible to establish the peak pedestrian traffic hours and demonstrate that users can spend more time at the station than on the bus. The improvement proposal was simulated in Vissim software in order to determine its reducing waiting times efficiency. The results show that users waiting times at the station were reduced by 25%. On the other hand, the pedestrian density and conflict points between pedestrians decreased by 44% and 73% respectively. Finally, increase in the pedestrian velocity of the corridors was obtained by 37%. / Tesis

The thesis investigates the impact of age-biased sampling on the accuracy of lifetime prediction models for traffic signs. The bias in question originates from age-biased sampling as a result of the inspection paradox. This phenomenon occurs because longer intervals have a higher probability of being observed compared to shorter intervals, leading to a skewed representation in the data. The research employs a dual approach: firstly, conducting an extensive analysis of real data on traffic sign longevity using a Weibull Survival Model. This analysis is based on the data set compiled by Saleh et al., (2023). Secondly, the study sets up a Monte Carlo simulation to systematically explore the effects of varying degrees and patterns of age bias on the sample. The simulation parameters are derived from the original Weibull Model parameters, obtained from the real dataset. This approach ensures that the simulations closely replicate the actual parameters and estimates. The comparison of the true shape, scale, intercept, and the coefficients associated with the covariates against the simulated estimates indicates a significant bias in the dataset. The study also examines the impact of this bias on the predictive capabilities of various models: Weibull Modeling, Cox Proportional Hazards, Kaplan Meier, and Random Survival Forest. This is done by comparing the true means and medians of the simulated data with the estimates from each model. The findings show that all models exhibit large deviations from the actual means and medians at varying bias levels in the simulated data. The accuracy of the predictions is measured using the Brier Score. This score also shows significant deviations from the prediction accuracy of the original Weibull Model applied to the real dataset, especially when the bias levels vary across simulated datasets. Given these findings, the study advises against using the aforementioned methods for lifetime modeling of traffic signs when there is age bias due to the inspection paradox.

This thesis provides a general methodology for classifying and describing many combinatoric problems, systematising and finding theoretical expressions for quantities of interest, and investigating their feasible numerical evaluation. Unifying notation and definitions are provided. Our knowledge of random allocations is also extended. This is achieved by investigating new processes, generalising known processes, and by providing a formal structure and innovative techniques for analysing them. The random allocation models described in this thesis can be classified as occupancy urn models, in which we have a sequence of urns and throw balls into them, and investigate static, waiting-time and dynamic processes. Various structures are placed on the relationship(s) between cells, balls, and the selection of items being distributed, including varieties, batch arrivals, taboo sets and blocking sets. Static, waiting-time and dynamic processes are investigated. Both without-replacement and with-replacement sampling types are considered. Emphasis is placed on the distributions of waiting-times for one or more events to occur measured from the time a particular event occurs; this begins as an abstraction and generalisation of a model of departures of cars parked in lanes. One of several additional determinations is the platoon size distribution. Models are analysed using combinatorial analysis and Markov Chains. Global attributes are measured, including maximum waits, maximum room required, moments and the clustering of completions. Various conversion formulae have been devised to reduce calculation times by several orders of magnitude. New and extended applications include Queueing in Lanes, Cake Displays, Coupon Collector's Problem, Sock-Sorting, Matching Dependent Sets (including Genetic Code Attribute Matching and the game SET), the Zig-Zag Problem, Testing for Randomness (including the Cake Display Test, which is a without-replacement test similar to the standard Empty Cell test), Waiting for Luggage at an Airport, Breakdowns in a Network, Learning Theory and Estimating the Number of Skeletons at an Archaeological Dig. Fundamental, reduction and covering theorems provide ways to reduce the number of calculations required. New combinatorial identities are discovered and a well-known one is proved in a combinatorial way for the first time. Some known results are derived from simple cases of the general models. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1309598 / Thesis (Ph.D.) -- University of Adelaide, School of Mathematical Sciences, 2007

A large part of Swedish medical care is expected to be provided from the primary health centers. However, these centers are experiencing challenges in terms of shortages of personnel, an increased volume of patients, higher workload, increasing queue lengths, and increasing costs. Addressing these issues at the primary health centers is important for both improving the operation at the local centers and the functionality of the Swedish healthcare system. This thesis aims to explore the primary health center operation, focusing on a typical public primary health center in Stockholm. This is done to find parameters that affect the flow of patients and develop a graphical model that serves as a foundation for further model development, simulations and optimization of good health. To address the complex and dynamic primary health center system, a system dynamics approach is adopted. A literature review was conducted to gain an understanding of the primary health center environment and to identify parameters that impact the primary health centers ability to operate and/or affect the quality of service towards patients. The model development involved constructing cases and extracting parameters that change over time. The parameter relationships were determined through interpretation and are supported by literature. The model was qualitatively validated with the assistance of expert feedback. The presented result is determined to capture the basic operation of the primary health center and the model can be used as a foundation for further simulations. / En stor del av den svenska sjukvården förväntas levereras från vårdcentraler. Vårdcentralerna står dock inför utmaningar när det gäller brist på personal, ökad patientvolym, högre arbetsbelastning, ökade kölängder och ökande kostnader. Att hantera dessa problem på vårdcentralerna är viktigt både för att förbättra den lokala verksamheten och funktionaliteten i svensk hälso- och sjukvård. Syftet med detta arbete är att undersöka vårdcentralens verksamhet och fokuserar på en typisk offentlig vårdcentral i Stockholm. Detta görs för att hitta parametrar som påverkar patientflödet, för att utveckla en grafisk modell som utgör en grund för vidare modellutveckling, simuleringar och optimering av god hälsa. För att adressera det komplexa och dynamiska vårdcentral-systemet antas ett system dynamiskt tillvägagångssätt. En litteraturgenomgång genomfördes för att få en förståelse för vårdcentralens miljö och identifiera parametrar som påverkar vårdcentralens förmåga att driva verksamheten och/eller påverkar kvaliteten på vården för patienter. Modellutvecklingen innebar att konstruera fall och extrahera parametrar som förändras över tid. Parametrarnas relationer bestämdes genom tolkning och stöds av litteratur. Modellen genomgick en kvalitativ valideringsprocess baserad på expertutlåtanden. Resultatet, den grafiska modellen, som presenteras anses fånga vårdcentralens grundläggande funktion och kan användas som grund för vidare simuleringar.

In Sweden, where a decentralized healthcare system is applied, all patients are registered at a primary healthcare center. To access most of the publicly funded specialized care clinics, patients need to be referred by a general physician at the primary healthcare center. However, long waiting times and queues to access specialized care clinics in Sweden, has been a serious problem and concern for decades. Addressing this issue is important for improving patients’ transition to specialized care and the functionality of the Swedish healthcare system. The aim of this thesis is to explore the Swedish healthcare system to analyze the transition of patients to specialized care clinics and identify the reasons for long waiting times and queues. This was done by analyzing the Swedish healthcare system and develop a serious game prototype which models the process of access to specialized care within the Swedish healthcare system. The prototype was used to understand the delay that happens in patients’ transition and access process to specialized care services.  A system analysis including a literature review is conducted to gain an understanding of the Swedish healthcare system and gather data to be used in the designed prototype. The outcome of the system analysis is a visual representation of the Swedish healthcare system including laws and stakeholders. A game frame is developed from the system analysis. Maps, tables, and a flow-diagram are developed to visualize patients’ access to specialized care. All of this was used to design the game prototype. The final prototype is developed through an iterative process, where several prototypes are designed and tested through game sessions with experts. The prototypes are evaluated after each game session. Finally, learning and findings gained from the prototypes design and the game sessions are documented. This includes reasons for long waiting times for a first visit at a specialized care clinic such as the structure of the Swedish healthcare system, mainly that the PHC is the foundation of the system. Staff shortages, and the need for a referral to access most of the specialized clinics are also discussed and stated along with other reasons. / I Sverige tillämpas decentraliserat sjukvårdssystem där alla patienter registeras vid en vårdscentral. För att få tillgång till de flesta offentligt finansierade specialistvårdsmottagningar remitteras patienterna av en allmänläkare vid vårdscentralen. Dock har långa väntetider och köer till specialiserad sjukvård varit ett allvarligt problem och bekymmer i Sverige i årtionden. Att hantera denna fråga är avgörande för att förbättra patienternas övergång till specialiserad vård och för att den svenska sjukvården ska fungera smidigt. Målet med detta projekt är att utforska det svenska sjukvårdssystemet för att analysera patientövergångar till specialistvårdsmottagningar och identifiera orsakerna till de långa väntetiderna och köerna. Detta uppnåddes genom att analysera det svenska sjukvårdssystemet och utveckla en prototyp av ett seröst simuleringssspel som simulerarr processen att få tillgång till specialiserad vård inom det svenska sjukvårdssystemet. Prototypen användes för att förstå förseningar som uppstår under patientövergångar och tillgång till specialvårdtjänster. En systemanalys inklusive en litteraturöversikt genomförs för att få en djupare förståelse för det svenska sjukvårdssystemet och samla in data som kommer att användas i den utformade prototypen. Resultatet av systemanalysen är en visuell representation av det svenska sjukvårdssystemet, inklusive juridiska lagar och berörda parter. Genom systemanalys utvecklas ett spelramverk. Kartor, tabeller och ett flödesschema utvecklas för att visuellt framställa patienternas tillgång till specialiserad vård. Allt detta användes sedan för att designa spelprototypen. Den slutliga prototypen utvecklas genom en iterativ process, där flera prototyper designas och testas genom spel sessioner med experter. Prototyperna utvärderas och dokumenteras efter varje spel-sessioner. Slutligen dokumenteras de lärdomar och resultat som erhållits från prototyputformningen och spel-sessionerna. Detta inkluderar orsaker till långa väntetider för ett första besök på en specialiserad vårdmottagning såsom strukturen i den svenska sjukvården, främst att PHC är grunden i systemet. Personalbrist och behovet av remiss för att komma åt de flesta specialiserade klinikerna diskuteras också och anges tillsammans med andra skäl.

1 Abstract and keywords in the English language Comparison of Czech and Slovak legal regulation of leave Abstract The dissertation contains an overview of labor law legislation, especially the regulation of holidays, in the territory of historical Bohemia, Moravia and Silesia on the one hand and in the territory of today's Slovakia on the other hand. For a better understanding of the issue, an overview of the development of working conditions and labor protection in a given time context in both cultural areas is also provided. I believe that the presented comparison of legal regulations in both territories is an interesting excursion not only in terms of labor law itself, but also in the field of legal history. I believe that in the presented summary of the work it provides important and interesting expanding knowledge in the field of labor law and social security law. In my opinion, similar work was lacking in our market, and therefore it can be assumed that in this direction it will contribute to its enrichment if it is possible to realize its book edition, which is under negotiation. An overview of the material described above is given in twelve chapters since the beginning of the 14th century, when labor relations developed in the Czech lands, about which written reports already exist. In the case of...
