Mòdul terminal punt de venda per a Tryton
Les aplicacions de planificació de recursos empresarials (en anglès Enterprise Resource Planning), també conegudes per ERPs són sistemes d’informació que s’integren a molts dels negocis actuals per gestionar els seus processos. Tryton és una aplicació ERP d’aquest tipus que permet gestionar diversos aspectes com les vendes, les compres, la facturació la comptabilitat, la gestió d’estoc, la fabricació,...
Aquest projecte consisteix en desenvolupar una aplicació per afegir les funcionalitats d’un terminal punt de venda a un ERP existent com és Tryton. L’aplicació desenvolupada s’encarrega principalment de crear i gestionar vendes al públic o minoristes en un establiment comercial. Permet gestionar el control d’estoc dels productes, el control de caixa, actualitzar la comptabilitat relacionada a les vendes i la impressió de tiquets de venda.
L’aplicació permet obtenir informació detallada sobre les vendes realitzades per saber en quin estat es troben, si ha estat abonada total o parcialment, si s’ha creat la factura i saber quins i quants pagaments s’han realitzat.
Una altre funcionalitat que ofereix l’aplicació és la possibilitat de poder crear operacions per introduir o extreure diners de la caixa, com per exemple retirar diners per ingressar al banc.
Tant les operacions com els pagaments d’una venda s’anoten en un registre des d’on s’actualitza automàticament la comptabilitat de l’empresa així com també consultar els assentaments comptables generats.
Aquest projecte afegeix noves funcionalitats a Tryton i optimitza el processos relacionats a les vendes al detall realitzades en un establiment
Simulating an automation plan in a 3D Printing manufacturing factory
Additive manufacturing technologies are growing in interest and it is clear that in a short time they have improve enormously. From being a lab technology for fast and small prototyping to enabling stable manufacturing of high-volume products. Every year, more manufacturers choose to adopt 3D printing technologies to produce end-user parts and sell them to compete with other more traditional methods. In this context, this thesis shows the path of using the HP MJF 5200 3D printing technology to scale up a 3D printing manufacturing plant and optimizing to achieve the highest profitability possible. To do so, a twin model and a cost model are built to allow fast and precise simulation and economic analysis of each scenario that the manufacturer would like to improve, providing production KPI’s and seeing the results before building and buying new equipment. The twin model will be validated with theoretical calculations to make sure it is accurate and it works as expected and all the simulation results will be presented and explained. At the end, when the plant is optimized using existing HP solutions, an automation plan will be defined to select the best automation projects in order to further increase the productivity and profitably of the factor
Extreme point rainfall temporal scaling: a long term (1805-2014) regional and seasonal analysis in Spain
This paper presents a regional and seasonal study of extreme point rainfall scaling from 10 min to 2 years. To do this, the highest point‐based rainfall list based on these temporal periods was calculated from the Spanish Meteorological Service (AEMET) precipitation databases with more than 11 000 rain‐gauge stations, with the longest series ranging from 1805 to 2014 (209 years). This list constitutes the register of single station largest amounts of precipitation in Spain ever recorded for selected periods, including for example the values for 2 h (193 mm), 24 h (817 mm) or 1 year (5503 mm). Rainfall extremes for 10 min periods are evenly distributed in coastal and inland areas. Daily precipitation extremes are mostly concentrated over the Mediterranean coast while from durations from one month to two years, extremes are located in southern and northwest Spain. Extreme data obtained were compared with existing worldwide rainfall records for equivalent periods. Results indicate that Spanish extreme rainfall scaling relating R depth (in mm) against D duration (in minutes) may be expressed as a potential law R = 21.8 D0.422 (R = 43.6 D0.507 for worldwide data). We propose the upper envelope line (greater or equal to extreme rainfall values) parallel to the potential fit law as a simple method to estimate possible extreme records for different time scales. Using this method, worldwide envelope may be expressed as R = 60.5 D0.507 and the Spanish envelope as R = 39.3 D0.422. Further analysis stratifying results by season and region show that seasonal scaling has more variability than regional scaling. The methodology described can be readily applied to other regions for which detailed rainfall databases exist. Applications of the results include using the scaling found as a reference for classification of heavy precipitation events for temporal scales
Anàlisis d'alternatives en els dissenys de restauració costanera per mitjà del modelatge numèric XBeach
Els processos hidrodinàmics i morfològics que interactuen en les zones costaneres són importants per plantejar projectes d'obres marítimes com la construcció de dics i ports o la restauració de platges. Entendre la física determina la composició de les platges és clau i complexa, sobretot en el transport de sediments i el trencament turbulent de les onades. Tanmateix, influeixen altres factors en l'estructura del perfil costaner com les dunes i barres que són sistemes dinàmics i s'adapten a les tempestes que s'encarreguen d'erosionar més el perfil o els períodes de calma que ajuden a recuperar la platja durant els períodes acretius.
Amb l'ajuda de diferents parametritzacions i formulacions que envolten el model numèric XBeach, s'estudiarà la física que interactua en el perfil d'una platja. El model permetrà realitzar una predicció aproximada de l'evolució morfològica/hidrodinàmica sota diferents condicions energètiques. Aquest model de transport de sediment ens ajudarà a entendre com funciona un model numèric, i a veure fins a quin punt els models de l´estat de l´art en transport de sediments són capaços de predir la formació d´una barra i els processos acretius.Los procesos hidrodinámicos y morfológicos que interactúan en las zonas costeras son importantes para plantear proyectos de obras marítimas como la construcción de diques y puertos o la restauración de playas.

Sin embargo, influyen otros factores en la estructura del perfil costero como las dunas y barras que son sistemas dinámicos y se adaptan a las tormentas que se encargan de erosionar más el perfil o períodos de calma que ayudan a recuperar la playa durante los períodos acretivos.
Con la ayuda de diferentes parametrizaciones y formulaciones que envuelven el modelo numérico XBeach, se estudiará la física que interactúa en el perfil de una playa. El modelo permitirá realizar una predicción aproximada de la evolución morfológica/hidrodinámica bajo distintas condiciones energéticas. Este modelo de transporte de sedimento nos ayudará a entender cómo funciona un modelo numérico, ya ver hasta qué punto los modelos del estado del arte en transporte de sedimentos son capaces de predecir la formación de una barra y los procesos acretivos.The hydrodynamic and morphological processes interacting in coastal areas are important for planning marine works projects such as the construction of seawalls and harbours or beach restoration. Understanding the physics determines the composition of beaches is key and complex, especially in sediment transport and turbulent wave breaking. However, other factors influence the structure of the coastal profile such as dunes and bars that are dynamic systems and adapt to storms that further erode the profile or periods of calm that help to restore the beach during accretive periods.
With the help of different parameterisations and formulations involving the XBeach numerical model, the physics interacting in the profile of a beach will be studied. The model will allow an approximate prediction of the morphological/hydrodynamic evolution under different energy conditions. This sediment transport model will help us to understand how a numerical model works, and to see to what extent state-of-the-art sediment transport models are able to predict bar formation and accretion processes
The role of motivation factors in exergame interventions for fall prevention in older adults: A systematic review and meta-analysis
Balance disorders and falls are common in the elderly population. Regular balance exercises are an evidence-based physical intervention to prevent falls in older adults, while patient motivation and adherence are important factors for intervention outcome. Exergames are a relatively new, alternative intervention for physical rehabilitation as they improve balance and strength in older adults. The aims of this systematic review and meta-analysis were to assess the (1) effect of motivation factors as per the Capability, Opportunity and Motivation model of Behavior change (COM-B) on the effectiveness of exergame interventions in healthy older adults, (2) effectiveness of exergames to improve balance in older healthy adults and, (3) impact of exergames on cognitive outcomes. Results show that motivation and capability components influence the general outcome of the exergame training. Motivational factors should thus be considered when setting-up an exergame intervention. Furthermore, exergame intervention appears to be a promising training method in comparison to traditional exercise training. However, exergame training in itself might not be sufficient to improve fall risk and cognitive performance
A new methodology to characterise the radar bright band using doppler spectral moments from vertically pointing radar observations
The detection and characterisation of the radar Bright Band (BB) are essential for many applications of weather radar quantitative precipitation estimates, such as heavy rainfall surveillance, hydrological modelling or numerical weather prediction data assimilation. This study presents a new technique to detect the radar BB levels (top, peak and bottom) for Doppler radar spectral moments from the vertically pointing radars applied here to a K-band radar, the MRR-Pro (Micro Rain Radar). The methodology includes signal and noise detection and dealiasing schemes to provide realistic vertical Doppler velocities of precipitating hydrometeors, subsequent calculation of Doppler moments and associated parameters and BB detection and characterisation. Retrieved BB properties are compared with the melting level provided by the MRR-Pro manufacturer software and also with the 0 °C levels for both dry-bulb temperature (freezing level) and wet-bulb temperature from co-located radio soundings in 39 days. In addition, a co-located Parsivel disdrometer is used to analyse the equivalent reflectivity of the lowest radar height bins confirming consistent results of the new signal and noise detection scheme. The processing methodology is coded in a Python program called RaProM-Pro which is freely available in the GitHub repository
E3MS: A traffic engineering prototype for autoprovisioning services in IP/DiffServ/MPLS networks
This paper presents the testbed definition, implementation and trials of a new strategy for traffic autoprovisioning for MPLS and IP/DiffServ. This is the proof of concept of a new scenario for traffic engineering, for selfconfiguring control and end-to-end quality of service management by means of a tool based on Web Services. The system is structured in 3 layers: A Graphical User Interface, a Network Elements layer (an interface to physical devices) and, in the middle, a Network Management System layer, where decisions about admission, load balancing, path selection, rerouting and bandwidth allocation per class are taken. The system includes Dynamic Resource Allocation (DRA) and Background Monitoring System (BMS) modules to globally manage network resources. The so-called Squatter and Legalization mechanisms are introduced as novelties added to traffic engineering. Those strategies permit the use of part of the available resources from other classes only while unused by the class owning them. The trials hav validated the management system, using Cisco routers.Postprint (published version
