PHC Production Management System Based on RFID

At present, in large precast concrete enterprises, the management over precast concrete component has been chaotic. Most enterprises take labor-intensive manual input method, which is time consuming and laborious, and error-prone. Some other slightly better enterprises choose to manage through bar-code or printing serial number manually. However, on one hand, this is also labor-intensive, on the other hand, this method is limited by external environment, making the serial number blur or even lost, and also causes a big problem on production traceability and quality accountability. Therefore, to realize the enterprise’s own rapid development and cater to the needs of the time, to achieve the automated production management has been a big problem for a modern enterprise. In order to solve the problem, inefficiency in production and traceability of the products, this thesis try to introduce RFID technology into the production of PHC tubular pile. By designing a production management system of precast concrete components, the enterprise will achieve the control of the entire production process, and realize the informatization of enterprise production management. RFID technology has been widely used in many fields like entrance control, charge management, logistics and so on. RFID technology will adopt passive RFID tag, which is waterproof, shockproof, anti-interference, so it’s suitable for the actual working environment. The tag will be bound to the precast component steel cage (the structure of the PHC tubular pile before the concrete placement), which means each PHC tubular pile will have a unique ID number. Then according to the production procedure, the precast component will be performed with a series of actions, put the steel cage into the mold, mold clamping, pouring concrete (feed), stretching, centrifugalizing, maintenance, mold removing, welding splice. In every session of the procedure, the information of the precast components can be read through a RFID reader. Using a portable smart device connected to the database, the user can check, inquire and management the production information conveniently. Also, the system can trace the production parameter and the person in charge, realize the traceability of the information. This system can overcome the disadvantages in precast components manufacturers, like inefficiency, error-prone, time consuming, labor intensity, low information relevance and so on. This system can help to improve the production management efficiency, and can produce a good economic and social benefits, so, this system has a certain practical value.

Using SeaDataNet Management System to preserve the XBT Data-Set of the Mediterranean Sea

significant amount of Expendable Bathythermograph (XBT) data has been collected in the Mediterranean Sea since 1999 in the framework of operational oceanography activities. The management and storage of such a volume of data poses significant challenges and opportunities. The SeaDataNet project, a pan-European infrastructure for marine data diffusion, provides a convenient way to avoid dispersion of these temperature vertical profiles and to facilitate access to a wider public. The XBT data flow, along with the recent improvements in the quality check procedures and the consistence of the available historical data set are described. The main features of SeaDataNet services and the advantage of using this system for long-term data archiving are presented. Finally, focus on the Ligurian Sea is included in order to provide an example of the kind of information and final products devoted to different users can be easily derived from the SeaDataNet web portal.

Soil management system effects on N availability and tree productivity in chestnut planatations under Mediterranean conditions

Soil tillage with chisel ploughing is the conventional soil management system in chestnut stands for fruit production in Northern Portugal. A study was developed to assess the effects of three soil management systems on in situ soil N mineralization dynamics, tree nutrition status and fruit productivity, in a 50-yr old chestnut stand. The treatments were: conventional tillage with a chisel ploughing twice a year (CT), no-tillage with rainfed improved pasture with leguminous and grasses plants (NIP), and no-tillage with spontaneous herbaceous vegetation - natural pasture (NP). The CT treatment showed a strong increase of the soil N mineral concentration following soil disturbance by tillage, but the cumulative net N mineralized along the year was significantly lower (51.8 kg ha-1) than in the NIP (85.1 kg ha-1) treatment. The NP treatment (65.9 kg ha-1) did not cause a reduction in the soil N mineralization when compared to the CT treatment. The mineralization rate (g mineralized N kg-1 total N) in 2004 was about 26, 30 and 38 in the treatments CT, NP and NIP, respectively. Treatments showed different soil N dynamics, the proportion of mineralized NO3--N being lower in the NP (10-48%) than in CT and NIP treatments (53-74%). Our study indicates that no-tillage systems improve the tree nutrition status and enhance productivity

OpenDataHub: an open dataset management system

This thesis presents a cloud-based software platform for sharing publicly available scientific datasets. The proposed platform leverages the potential of NoSQL databases and asynchronous IO technologies, such as Node.JS, in order to achieve high performances and flexible solutions. This solution will serve two main groups of users. The dataset providers, which are the researchers responsible for sharing and maintaining datasets, and the dataset users, that are those who desire to access the public data. To the former are given tools to easily publish and maintain large volumes of data, whereas the later are given tools to enable the preview and creation of subsets of the original data through the introduction of filter and aggregation operations. The choice of NoSQL over more traditional RDDMS emerged from and extended benchmark between relational databases (MySQL) and NoSQL (MongoDB) that is also presented in this thesis. The obtained results come to confirm the theoretical guarantees that NoSQL databases are more suitable for the kind of data that our system users will be handling, i. e., non-homogeneous data structures that can grow really fast. It is envisioned that a platform like this can lead the way to a new era of scientific data sharing where researchers are able to easily share and access all kinds of datasets, and even in more advanced scenarios be presented with recommended datasets and already existing research results on top of those recommendations.

Development of a responsive fisheries management system for the Portuguese crustacean bottom trawl fishery: Lessons learnt

A prototype for a Responsive Fisheries Management System (RFMS) was developed in the context of the European FP7 project EcoFishMan and tested on the Portuguese crustacean trawl fishery. Building on Results Based Management principles, RFMS involves the definition of specific and measurable objectives for a fishery by the relevant authorities but allows resource users the freedom to find ways to achieve the objectives and to provide adequate documentation. Taking into account the main goals of the new Common Fisheries Policy, such as sustainable utilization of the resources, end of discards and unwanted catches, a management plan for the Portuguese crustacean trawl fishery was developed in cooperation with the fishing industry, following the process and design laid out in the RFMS concept. The plan considers biological, social and economic goals and assigns a responsibility for increased data collection to the resource users. The performance of the plan with regard to selected indicators was evaluated through simulations. In this paper the process towards a RFMS is described and the lessons learnt from the interaction with stakeholders in the development of an alternative management plan are discussed.

Il Pavement Management System di un'infrastruttura viaria: il caso del quartiere di Campo di Marte del Comune di Firenze

L’elaborato si apre presentando il concetto di Pavement Managemet System (PMS), un modello di gestione degli interventi di manutenzione che le pavimentazioni di una rete stradale dovranno subire nel corso del tempo. Uno dei punti di forza del Pavement Management System, è costituito dalla diretta comparazione tra i costi delle strategie programmate e i relativi benefici, che consente di scegliere l’alternativa più efficace. Nel secondo capitolo viene descritto il catasto stradale, strumento di fondamentale importanza per la gestione del patrimonio stradale e per il funzionamento del Pavement Management System. Esso infatti è l’elemento di collegamento tra la sicurezza e la programmazione della manutenzione. Il terzo capitolo espone il caso di studio del quartiere di Campo di Marte del Comune di Firenze. L’elemento di partenza di questo capitolo è il database dei sinistri stradali, il quale aiuta ad individuare alcune carenze della sovrastruttura che potrebbero essere causa di disagi o addirittura di incidenti. Dall’analisi si possono quindi dedurre utili indicazioni sul tipo di interventi che si rendono necessari per garantire la sicurezza e sulle priorità degli interventi stessi. Successivamente vengono descritte le modalità di rilievo per il quartiere oggetto del caso di studio ed esposti i risultati. Questi, uniti a quelli degli indici di stato prestazionali, danno vita alla pianificazione degli interventi di manutenzione necessari. Il quarto ed ultimo capitolo contiene i piani di manutenzione, con la relativa catalogazione degli interventi di manutenzione e riabilitazione. Questi vengono pianificati con l’ausilio dei risultati provenienti dai rilievi e dagli indici di stato prestazionali. Infine vengono presentati a titolo di esempio, tre casi reali di piano operativo degli interventi sulle pavimentazioni di strade appartenenti al quartiere di Campo di Marte.

Fleet Management System for Search and Rescue Operations

Over one million people lost their lives in the last twenty years from natural disasters like wildfires, earthquakes and man-made disasters. In such scenarios the usage of a fleet of robots aims at the parallelization of the workload and thus increasing speed and capabilities to complete time sensitive missions. This work focuses on the development of a dynamic fleet management system, which consists in the management of multiple agents cooperating in order to accomplish tasks. We presented a Mixed Integer Programming problem for the management and planning of mission’s tasks. The problem was solved using both an exact and a heuristic approach. The latter is based on the idea of solving iteratively smaller instances of the complete problem. Alongside, a fast and efficient algorithm for estimation of travel times between tasks is proposed. Experimental results demonstrate that the proposed heuristic approach is able to generate quality solutions, within specific time limits, compared to the exact one.

Käytöntukijärjestelmän toiminnoista saatavat hyödyt ja niiden analysointi

Käytöntukijärjestelmä on ohjelmistokokonaisuus, jota käytetään käyttötoiminnan päätöksenteon tukena useissa verkkoyhtiöissä. Järjestelmä sisältää useita erilaisia sovelluksia, joiden käytön perustana on käytöntukijärjestelmään integroituneiden tietojärjestelmien tietojen hyödyntäminen. Tässä diplomityössä tutkitaan käytöntukijärjestelmän eri toimintoja ja analysoidaan niistä saatavia hyötyjä. Hyötyjen suuruuteen vaikuttaa merkittävästi verkon laajuus, automaatioaste sekä käyttöhenkilökunnan koulutustaso. Lopputuloksena verrataan käytöntukijärjestelmästä saatavaa maksimaalista hyötyä keskeytyskustannuksissa, järjestelmän käyttöönotosta aiheutuviin kustannuksiin. Lisäksi työssä arvioidaan verkkoyhtiön laajuudesta riippuen, onko sen järkevää hankkia käytöntukijärjestelmää ostamalla se itse, palveluntarjoajan kautta tai ei ollenkaan.
