PRIVED: a Privacy Model for Heterogeneous Mobile Networks

We propose a network-oriented privacy model (PRIVED) composed by a well defined information model, using events, information sets and relationships to define the conceptual privacy relationships that can occur in the network. We propose formal rules and a network instantiation, using linkability and correlation as the main tools for network applicability. We also use the model to determine the best approaches towards privacy protection in the network, resulting in a vertical/horizontal network privacy dichotomy

Prediction of carcass composition in vivo by slaughter weight and ultrasound measurements in Churro Galego Bragançano local breed lambs

Forty Churro Galego Bragançano local breed lambs (20 females and 20 males) with an mean live weight of 19.3 kg ( 10 to 28.5 kg) were scanned by ultrasound to M. Longissimus dorsi depth (MLDD), subcutaneous fat thickness (SFT) between the 12th-1 3th dorsal vertebra (D 12), l st-2nd (Ll ) and 3rd-4th (L3) lumbar vertebra and breast bone tissue thickness (BET) at 2nd (S2), 3rd (S3) and 4th sternebra. Lambs were slaughtered after 24-h fast ing. Carcasses were cooled at 4 °C for 24 h. and halved carefully. The left side was divided into eight standardized commercial joints: leg, chump, loin. Ribs, anterior ribs, shoulder, breast and neck. Each joint was then dissected into muscle, subcutaneous fat. intermuscular fat and bone. The in vivo ultrasound measurements plus slaughter weight were fitted to predict carcass tissue composition by stepwise regression analysis. All the developed models were highly significant (P<0.001) and explained 60, 76,64 and 74% of the muscle, subcutaneous fat, intermuscular fat and bone variation, respectively. The models residual standard deviations were lower than 20 g kg-

User centric community clouds

With the evolution in cloud technologies, users are becoming acquainted with seamless service provision. Nevertheless, clouds are not a user centric technology, and users become completely dependent on service providers. We propose a novel concept for clouds, where users self-organize to create their clouds. We present such an architecture for user-centric clouds, which relies on self-managed clouds based on doctrine and on identity management concepts

IES an open system for underwater inspection

This paper describes the specification and design of a prototype of a low cost open system for the inspection of underwater structures based on a remotely operated underwater vehicle under the project IES, a 3 year long effort funded by the Portuguese R&D program Praxis XXI. Unlike commercial approaches, a modular open system characterised by the incorporation of an on-board computer allowing for advanced control capabilities is envisaged. The control console is based on a standard PC and the tether is used only for power delivery and to establish a simple communication channel. In this project, we use advanced hybrid control techniques for sophisticated semi-autonomous operation management and control. The control architecture reuses part of the one designed for the underwater vehicle Isurus operated by the Laboratory of Underwater Systems and Technologies of Porto University. The implementation is designed in order to allow for multiple sensor configurations specified as add-ins. This leads to a dynamic, scalable and flexible system that can be easily configured according to the user specifications

Chromatographic analysis of honey ceramic artefacts

Honey was the main sweetening agent in the ancient world; it is mentioned in literary sources and archaeologically documentedall over the Mediterranean basin. Its production extended throughout different parts of the Roman Empire, with importanteconomic impacts on family economies, both as a foodstuff and as a commercial product. This paper focuses on the chromato-graphic analysis of Roman Iberian honeypots and ceramic beehives, identifying tracer characteristics from ancient honey insherds from seven honeypots and three beehives. The obtained results present an important contribution to the knowledge of thelocal Roman Iberian economy, particularly relating to the production, transport and trade of honey in locally manufacturedceramic containers.This work received financial support from theEuropean Regional Development Fund (ERDF) through COMPETE—Operational Competitiveness Programme and national funds provided byFCT—Foundation for Science and Technology under the project UID/QUI/50006/2013.

Estudio de mejora de procesos del servicio de la plataforma elevadora GP40 en Maquinza Perú S.A.C.

La presente investigación es un estudio de mejora de los procesos del servicio de la plataforma elevadora GP40 en la empresa Maquinza Perú. S.A.C. El estudio se llevó a cabo en el periodo enero - diciembre del 2016, como responsable del área de operaciones e ingeniería. Se detectó un creciente nivel de reclamos con respecto al servicio de las plataformas elevadoras sobre mástil GP40, llamadas comercialmente plataformas GP40 o plataformas de cremallera. Estos reclamos o molestias se notaban en base a los correos que llegaban a la central desde las diferentes obras que atendía la empresa. La insatisfacción se generaba por la demora en el armado de la plataforma GP40 y la falta de información de un tiempo estándar de armado que necesitaba el cliente para programar sus futuras acciones en el proyecto con la maquinaria. Si no se cumplía con el tiempo indicado, era una pérdida para el cliente de costo de mano de obra parada, asimismo si no se establecía un tiempo estándar de armado, el cliente no podía anticiparse para contratar el personal para los trabajos posteriores. Implementando herramientas de ingeniería, se detecta los tres ejes principales que generan el problema de la empresa, siendo la falta de un tiempo estándar de armado de la plataforma GP40, falta de un procedimiento escrito de armado de la maquinaria y por último orden en el almacén de la empresa. Con los ejes detectados y en un trabajo en conjunto con el personal involucrado, se desarrollaron las soluciones óptimas enfocadas en tres objetivos específicos. las mismas que lograron eliminar los problemas y mejorar la preferencia del cliente por los servicios de la plataforma elevadora GP40 en la empresa Maquinza Perú S.A.C., obteniéndose resultados favorables los cuales se pueden observar en el segundo periodo de estudio correspondiente a Julio – Diciembre del 2016.The present investigation is an improvement study in the service processes of the mast climbing work platform GP40 of the company Maquinza Peru S.A.C. The study took place in the period for January – December 2016, being responsible of the operation an engineering area. We detected an uprising level of claims concerning the mast climbing GP40 service. Commercially called platforms GP40 or rack elevated platforms. This claims or inconveniences were noticed due to the emails that were sent to the main office from different construction sites that the company served. The discontent was generated by the delay in setting up the mast climbing GP40, and the lack of information of a standard set up time that the client needed to plan their future activities in the project with the mast climbing GP40. If the deadline was not met, it was a loss for the client, downtime cost. Also, if there was no standard set up time, the client could not anticipate to hire the qualified staff for the subsequent jobs. Implementing engineering tools, we can detect the three main axis that generate the company main issue, which is the lack of a standard set up time of the mast climbing GP40, the lack of a written procedure to set up the machinery and last but not least order in the company warehouse. With the axis detected and in a group work altogether with the involved staff, optimized solutions were developed focusing in three specific objectives. The ones that got to eliminate the issues and improve the client’s preference for the service of the mast platform GP40 in Maquinza Peru S.A.C. company, which we can observe in the second period of study for July-December 2016
