Sistema de almacén y dispensación robotizada de productos farmacéuticos

Actualmente, las necesidades de mejora en gestión de stocks y la mayor disponibilidad de sistemas automáticos, están haciendo que muchas empresas inviertan en técnicas modernas para almacenamiento y manipulación de productos. Esta inquietud también ha llegado a las farmacias, que de forma lenta pero firme se van apuntando a su robotización. Uno de los principales problemas a los que se enfrentan las farmacias es la pérdida de tiempo en la gestión y búsqueda de medicamentos, provocando situaciones negativas como las esperas, la falta de tiempo para una atención más personalizada y como consecuencia, la pérdida de clientes. Este inconveniente y la necesidad de mejora en la gestión de los stocks han hecho que aparezcan los Sistemas de dispensación automática de productos farmacéuticos. El dispensador automático facilita el trabajo del farmacéutico al automatizar la búsqueda de la medicina requerida, aumentando la dedicación al cliente y reduciendo los tiempos no productivos y las colas. El presente estudio desarrolla un sistema de dispensación automático de fármacos aplicado a farmacias con una rotación de medicamentos media/ baja, valorando tanto su viabilidad técnica como económica. El almacén propuesto es de tipo caótico con sistema de carga, almacenamiento y descarga completamente automáticos. La mayoría de diseños y conceptos expuestos en este trabajo son de desarrollo propio del autor con el único objetivo de la búsqueda de nuevas soluciones para conseguir un sistema de almacenamiento efectivo y de máximo rendimiento.

Control de 6 respiròmetres i anàlisi de les dades

L’aplicació de tècniques respiromètriques és de recent innovació dins l’estudi dels tractaments d’aigües residuals. Aquest conjunt de tècniques ens permeten analitzar dos processos importants dins una planta de tractament biològic: el creixement de la biomassa i el consum del substrat. Això fa que siguin una eina amb gran potencial en l’avaluació dels sistemes de tractament biològic d’aigües residuals. L’objectiu principal d’aquest treball es la realització d’una aplicació capaç de controlar el funcionament de 6 respiròmetres, gestionant el procés del mostreig de les respirometries i l’anàlisi de les dades obtingudes, per obtenir el substrat ràpidament biodegradable (Ss) per a mostres d’aigua residual, i la taxa màxima de creixement específic per a mostres de compost. L’aplicació s’ha desenvolupat sobre l’entorn Microsoft Access, on s’integren la base de dades amb les mostres i els resultats de les respirometries, i els formularis de control que ens permeten gestionar i controlar els processos de mostreig i anàlisi. L’aplicació es comunica amb els sensors i actuadors dels respiròmetres a través del control ActiveX, ADS-OCX, subministrat per TwinCAT, que ens permet capturar les lectures dels sensors i controlar el funcionament dels actuadors. Aquests elements estan connectats a mòduls descentralitzats d’entrades i sortides, comunicats mitjançant el bus Ethernet amb el PC-Industrial, on s’executa l’aplicació. Un cop finalitzada l’aplicació, aquesta controla correctament el mostreig de les respirometries, registrant les lectures de les sondes a la base de dades i controlant l’activació de les vàlvules del respiròmetre. Partint de les mostres obtingudes, o de respirometries externes, importades des de Microsoft Excel, s’ha comprovat el correcte funcionament en el càlcul del substrat ràpidament biodegradable (Ss) i la taxa màxima de creixement específic. Amb l’aplicació desenvolupada, s’ha comprovat el funcionament i les possibilitats que ens ofereix TwinCAT alhora de controlar mòduls d’entrades i sortides, així com la seva comunicació amb aplicacions com Microsoft Access. Això pot afavorir a la utilització d’aquest tipus de tecnologia, per aplicacions futures.

Calculation of radio electrical coverage in Medium-Wave Frequencies

The aim of this project is to accomplish an application software based on Matlab to calculate the radioelectrical coverage by surface wave of broadcast radiostations in the band of Medium Wave (WM) all around the world. Also, given the location of a transmitting and a receiving station, the software should be able to calculate the electric field that the receiver should receive at that specific site. In case of several transmitters, the program should search for the existence of Inter-Symbol Interference, and calculate the field strenght accordingly. The application should ask for the configuration parameters of the transmitter radiostation within a Graphical User Interface (GUI), and bring back the resulting coverage above a map of the area under study. For the development of this project, it has been used several conductivity databases of different countries, and a high-resolution elevation database (GLOBE). Also, to calculate the field strenght due to groundwave propagation, it has been used ITU GRWAVE program, which must be integrated into a Matlab interface to be used by the application developed.

Aplicação de Zr/Ti-PILC no processo de adsorção de Cu(II), Co(II) e Ni(II) utilizando modelos físico-químicos de adsorção e termodinâmica do processo

The aim of this investigation is to study how Zr/Ti-PILC adsorbs metals. The physico-chemical proprieties of Zr/Ti-PILC have been optimized with pillarization processes and Cu(II), Ni(II) and Co(II) adsorption from aqueous solution has been carried out, with maximum adsorption values of 8.85, 8.30 and 7.78 x10-1 mmol g-1, respectively. The Langmuir, Freundlich and Temkin adsorption isotherm models have been applied to fit the experimental data with a linear regression process. The energetic effect caused by metal interaction was determined through calorimetric titration at the solid-liquid interface and gave a net thermal effect that enabled the calculation of the exothermic values and the equilibrium constant.

Lämpöpumppujen vaikutukset sähköverkkoliiketoiminnan kannalta

Energiatehokkuus sekä ilmastonmuutos ovat aiheuttaneet pyrkimyksen vähentää kokonaisenergiankulutuksia erilaisissa rakennuksissa. Lämmitysjärjestelmissä tämä on näkynyt voimakkaana lämpöpumppumäärien kasvuna. Lämpöpumput vaikuttavat erilaisissa rakennus- ja lämmitystyypeissä myös sähköenergiankulutukseen. Lämpöpumppujen käytöstä saadaan eniten hyötyä lämmityskustannuksiin sähkölämmitteisissä rakennuksissa. Seurauksena on, että tällaisen rakennuksen sähkönkulutus ja siten myös sähkölasku pienenevät. Toisaalta muihin kuin sähkölämmitteisiin rakennuksiin asennettu lämpöpumppu kasvattaa sähköenergiankulutusta. Lämpöpumppuihin integroitu jäähdytysominaisuus myös tavallisesti lisää sähkönkulutusta. Tämän tutkimuksen tarkoituksena on selvittää, kuinka lämpöpumput vaikuttavat sähköenergiankulutukseen. Vaikutuksia tutkitaan sähköverkkoyhtiöiden kannalta sähköenergian ja liikevaihdon osalta. Tarkastelussa käytetään neljää yleisintä lämpöpumpputyyppiä, ja niiden toimintaa verrataan eri rakennustyyppien lämmitysjärjestelmiin. Työssä käsitellään lämpöpumppujen toimintaa ja käytettävyyttä muiden lämmitysmenetelmien korvaajina tai lisänä. Tämän kirjallisen työn lisäksi on tehty laskentaohjelma, joka on perusteena työssä esitetyille tuloksille. Sen tarkoituksena on selvittää lämpöpumppujen vaikutukset sähköverkkoliiketoimintaan energiayhtiöissä. Vaikutukset yksittäiseen energiayhtiöön ovat eniten riippuvaisia lämpöpumppujen asennuskohteista, lämpöpumppujen toiminnasta ja lämpöpumpputyypistä. Kuluttajat tulevat määräämään vaikutusten suuruuden, koska lämpöpumppujen lukumäärällä ja käytöllä on sähköenergiankulutukseen huomattava merkitys. Vaikutus sähköenergiaan energiayhtiöiden kannalta voi yleisesti ottaen olla 2020-luvulle mentäessä merkittävä. Tutkittavassa verkkoyhtiössä vaikutuksen sähköenergiaan arvioidaan olevan 10 % luokkaa yhdeltä vuodelta verrattuna tämän päivän kokonaissähköenergiankulutukseen. Vaikutus verkkoliikevaihtoon on arviolta puolet pienempi. Tällaiset tulokset edellyttävät lämpöpumppumäärän moninkertaistumista nykyisestä, mikä on myös odotettavissa.

Concentrated Winding Multiphase Permanent Magnet Machine Design and Electromagnetic Properties – Case Axial Flux Machine

Concentrated winding permanent magnet machines and their electromagnetic properties are studied in this doctoral thesis. The thesis includes a number of main tasks related to the application of permanent magnets in concentrated winding open slot machines. Suitable analytical methods are required for the first design calculations of a new machine. Concentrated winding machines differ from conventional integral slot winding machines in such a way that adapted analytical calculation methods are needed. A simple analytical model for calculating the concentrated winding axial flux machines is provided. The next three main design tasks are discussed in more detail in the thesis. The magnetic length of the rotor surface magnet machines is studied, and it is shown that the traditional methods have to be modified also in this respect. An important topic in this study has been to evaluate and minimize the rotor permanent magnet Joule losses by using segmented magnets in the calculations and experiments. Determination of the magnetizing and leakage inductances for a concentrated winding machine and the torque production capability of concentrated winding machines with different pole pair numbers are studied, and the results are compared with the corresponding properties of integral slot winding machines. The thesis introduces a new practical permanent magnet motor type for industrial use. The special features of the machine are based on the option of using concentrated winding open slot constructions of permanent magnet synchronous machines in the normal speed ranges of industrial motors, for instance up to 3000 min-1, without excessive rotor losses. By applying the analytical equations and methods introduced in the thesis, a 37 kW 2400 min-1 12-slot 10-pole axial flux machine with rotor-surfacemounted magnets is designed. The performance of the designed motor is determined by experimental measurements and finite element calculations.

Calculation of the carbon footprint of Finnish barley products - methodology and possible applications

The purpose of this thesis was to define how product carbon footprint analysis and its results can be used in company's internal development as well as in customer and interest group guidance, and how these factors are related to corporate social responsibility. From-cradle-to-gate carbon footprint was calculated for three products; Torino Whole grain barley, Torino Pearl barley, and Elovena Barley grit & oat bran, all of them made of Finnish barley. The carbon footprint of the Elovena product was used to determine carbon footprints for industrial kitchen cooked porridge portions. The basic calculation data was collected from several sources. Most of the data originated from Raisio Group's contractual farmers and Raisio Group's cultivation, processing and packaging specialists. Data from national and European literature and database sources was also used. The electricity consumption for porridge portions' carbon footprint calculations was determined with practical measurements. The carbon footprint calculations were conducted according to the ISO 14044 standard, and the PAS 2050 guide was also applied. A consequential functional unit was applied in porridge portions' carbon footprint calculations. Most of the emissions from barley products' life cycle originate from primary production. The nitrous oxide emissions from cultivated soil and the use and production of nitrogenous fertilisers contribute over 50% of products' carbon footprint. Torino Pearl barley has the highest carbon footprint due to the lowest processing output. The reductions in products' carbon footprint can be achieved with developments in cultivation and grain processing. The carbon footprint of porridge portion can be reduced by using domestically produced plant-based ingredients and by making the best possible use of the kettle. Carbon footprint calculation can be used to determine possible improvement points related to corporate environmental responsibility. Several improvement actions are related to economical and social responsibility through better raw material utilization and expense reductions.

Polarimetric 3D integral imaging in photon-starved conditions

We develop a method for obtaining 3D polarimetric integral images from elemental images recorded in low light illumination conditions. Since photon-counting images are very sparse, calculation of the Stokes parameters and the degree of polarization should be handled carefully. In our approach, polarimetric 3D integral images are generated using the Maximum Likelihood Estimation and subsequently reconstructed by means of a Total Variation Denoising filter. In this way, polarimetric results are comparable to those obtained in conventional illumination conditions. We also show that polarimetric information retrieved from photon starved images can be used in 3D object recognition problems. To the best of our knowledge, this is the first report on 3D polarimetric photon counting integral imaging.

Self-condensation of n-(N-propyl)butanimine: NMR and mass spectral analyses and investigation by theoretical calculation

The stability of N-propylbutanimine (1) was investigated under different experimental conditions. The acid-catalyzed self-condensation that produced the E-enimine (4) and Z-inimine (5) was studied by experimental analyses and theoretical calculations. Since the calculations for the energy of 5 indicated that it had a lower energy than 4, yet 4 was the principal product, the self-condensation of 1 must be kinetically controlled.

Tehohäviöiden laskentaa varten toteutettu laskentasovellus on esitelty periaatteellisina vuokaavioina ja sovelluksella saatavia tuloksia on esitetty ja vertailtu mitattuihin tuloksiin.

Reação de Brachiaria spp. e Panicum maximum a Pratylenchus brachyurus

O sistema plantio direto é utilizado em extensas áreas agrícolas do Brasil, condição que pode propiciar o aumento dos danos causados pelos fitonematóides na cultura principal, na dependência da reação das plantas utilizadas como coberturas vegetais. O capim-colonião (Panicum maximum) e as braquiárias (Brachiaria spp.) podem ser utilizadas em áreas infestadas por Meloidogyne incognita e M. javanica, pois não são hospedeiras dessas espécies, mas sua resposta ao nematóide Pratylenchus brachyurus tem sido pouco estudada. Por essa razão, dois experimentos de casa de vegetação foram realizados, com o objetivo de caracterizar a reação de cinco espécies e um híbrido de braquiária [Brachiaria decumbens, B. brizantha, B. humidicola, B. dyctioneura, B. ruziziensis e capim 'Mulato' (B. ruziziensis x B. brizantha)] e dois cultivares de P. maximum ('Mombaça' e 'Tanzânia') ao nematóide P. brachyurus. Os experimentos foram semelhantes, diferindo pela origem dos isolados de P. brachyurus, Pb20 oriundo de raízes de quiabeiro e Pb24 de algodoeiro. A população final dos nematóides do substrato e das raízes foi avaliada 118 dias após a inoculação para Pb20 e 131 dias para Pb24. Os resultados mostraram que todas as poáceas testadas hospedam P. brachyurus, mas em diferentes graus. Capim-colonião e capim 'Mulato' mostraram ser bons hospedeiros de P. brachyurus, com fator de reprodução (FR = Pf/Pi) entre 4,96 e 12,17 para Pb20 e entre 10,38 e 13,18 para Pb24, devendo assim ser evitados como coberturas vegetais em campos infestados com esse nematóide. Por seu turno, B. dyctioneura provou ser mau hospedeiro de P. brachyurus, com FR = 1,01 - 1,32.

Utilization of a Time Domain Simulator in the Technical and Economic Analysis of a Wind Turbine Electric Drive Train

The amount of installed wind power has been growing exponentially during the past ten years. As wind turbines have become a significant source of electrical energy, the interactions between the turbines and the electric power network need to be studied more thoroughly than before. Especially, the behavior of the turbines in fault situations is of prime importance; simply disconnecting all wind turbines from the network during a voltage drop is no longer acceptable, since this would contribute to a total network collapse. These requirements have been a contributor to the increased role of simulations in the study and design of the electric drive train of a wind turbine. When planning a wind power investment, the selection of the site and the turbine are crucial for the economic feasibility of the installation. Economic feasibility, on the other hand, is the factor that determines whether or not investment in wind power will continue, contributing to green electricity production and reduction of emissions. In the selection of the installation site and the turbine (siting and site matching), the properties of the electric drive train of the planned turbine have so far been generally not been taken into account. Additionally, although the loss minimization of some of the individual components of the drive train has been studied, the drive train as a whole has received less attention. Furthermore, as a wind turbine will typically operate at a power level lower than the nominal most of the time, efficiency analysis in the nominal operating point is not sufficient. This doctoral dissertation attempts to combine the two aforementioned areas of interest by studying the applicability of time domain simulations in the analysis of the economicfeasibility of a wind turbine. The utilization of a general-purpose time domain simulator, otherwise applied to the study of network interactions and control systems, in the economic analysis of the wind energy conversion system is studied. The main benefits of the simulation-based method over traditional methods based on analytic calculation of losses include the ability to reuse and recombine existing models, the ability to analyze interactions between the components and subsystems in the electric drive train (something which is impossible when considering different subsystems as independent blocks, as is commonly done in theanalytical calculation of efficiencies), the ability to analyze in a rather straightforward manner the effect of selections other than physical components, for example control algorithms, and the ability to verify assumptions of the effects of a particular design change on the efficiency of the whole system. Based on the work, it can be concluded that differences between two configurations can be seen in the economic performance with only minor modifications to the simulation models used in the network interaction and control method study. This eliminates the need ofdeveloping analytic expressions for losses and enables the study of the system as a whole instead of modeling it as series connection of independent blocks with no lossinterdependencies. Three example cases (site matching, component selection, control principle selection) are provided to illustrate the usage of the approach and analyze its performance.
