A Wireless Monitoring System for Pulse-oximetry Sensors

This paper presents a wireless medical monitoring system. The system permits to receive and process in a single concentrator node (e.g. a laptop or a simple handheld device) the pulse-oximetry signals from one ore several monitored patients without using any wired infrastructure. The system, which is based on a piconet of Bluetooth sensors, can retransmit the medical signals by WLAN and GPRS. The paper describes the practical application scenarios in which this type of systems could be of great utility.Ministerio de Educación y Ciencia TIC2003- 07953-C02-0

Catálogo nacional de los moluscos marinos de las aguas españolas

A checklist of marine Mollusca recorded in Spanish jurisdictional waters is presented, based on a thorough literature search and a limited input of recent field work. The list is detailed according to the five demarcations of the Marine Strategy Framework Directive (NOR, Spanish north coast; SUR, Spanish coast of the Gulf of Cádiz; ESAL, Strait of Gibraltar and Alboran Sea; LEBA, East coast of Spain and Balearic Islands; CAN, the Canary Islands). The list differentiates coastal species living from the supralittoral zone to the shelf break, deep-sea benthic or demersal species, and holoplanktonic species, and also distinguishes between non-indigenous species and species endemic to a particular demarcation. A total of 2466 marine Mollusca species have been reported from Spanish waters, of which 1126 are recorded only from waters surrounding the Iberian Peninsula, 498 are recorded from the Canaries only, and 842 are shared. That total number represents around 5.5% of the global marine molluscan richness. Shore and shelf species are the most numerous (1837), followed by deep-sea benthic species (490) and pelagic species (139), but the contribution of the deep-sea species is most noteworthy in NOR. All eight molluscan classes were represented, but solenogastres and scaphopods were notably more represented than usual in NOR. Species richness in SUR and ESAL was higher than would be expected from their areas, supporting the claim that Andalusian waters have an exceptionally diverse molluscan fauna. Thirteen species collected from INDEMARES cruises are here reported for the first time in Spanish waters. The species recorded in Spanish seas represent more than half of the 4340 species of Mollusca recorded within the scope of the European Register of Marine Species, making this the highest species count in European seas. The Canary Islands demarcation holds by far the largest number of endemic species (127), but special mention is needed regarding the ca. 20 species endemic to the Strait of Gibraltar, a highly anomalous chorotype in the marine realm. The number of non-indigenous species (38) is surprisingly low compared with that of species known in the Mediterranean Sea, amounting to hardly 1.5% of the total and supporting the view that a high number of native species tends to reduce invasion success. The list is seen as a much needed tool for the identification of priority areas for biodiversity conservation, but requires permanent attention and curating in order to remain up-to-date.Se presenta el catálogo actualizado de los moluscos marinos citados en las aguas jurisdiccionales españolas, basado en una exhaustiva revisión bibliográfica y en los hallazgos de campañas recientes. La lista se detalla para las cinco demarcaciones de la Directiva Marco sobre la Estrategia Marina (NOR: costas del norte de España; SUR: costas españolas del golfo de Cádiz, ESAL: estrecho de Gibraltar y mar de Alborán; LEBA: costas del este de España e islas Baleares; CAN: islas Canarias). En la lista se diferencia entre las especies costeras (las que viven desde la zona supralitoral hasta el borde de la plataforma continental), las especies bentónicas o demersales de aguas profundas y las especies holoplanctónicas, y también se indican las especies alóctonas y las que son endémicas para cada una de las demarcaciones. En total, se han citado 2.466 especies de moluscos marinos en aguas españolas, de las cuales 1.126 se conocen sólo en aguas peninsulares y baleares, 498 sólo en aguas canarias, mientras que 842 comparten ambas áreas. Ese número total representa alrededor del 5,5% de la riqueza específica global de moluscos marinos. Las especies costeras y de la plataforma continental son las más numerosas (1.837), seguidas de las especies de aguas profundas (490) y pelágicas (139), pero la contribución de las especies profundas es especialmente notable en NOR. Están representadas las ocho clases que comprende el filo Mollusca, con una destacable representación de los solenogastros y escafópodos en NOR. La riqueza de especies en SUR y ESAL es superior a la que cabría esperar de sus respectivas áreas, lo que apoya la afirmación de que las costas y aguas andaluzas albergan una malacofauna especialmente diversa. Trece especies recogidas en campañas del proyecto INDEMARES se citan aquí por primera vez en aguas españolas. Las especies registradas en los mares españoles suponen más de la mitad de las 4.340 especies de moluscos registradas en el ámbito geográfico del Registro Europeo de Especies Marinas, lo que supone el mayor número de especies de los países europeos. La demarcación de las islas Canarias es la que contiene con diferencia el mayor número de endemismos (127), pero merecen una mención especial las cerca de 20 especies endémicas del área del estrecho de Gibraltar, un corotipo muy anómalo en el medio marino. El número de especies alóctonas (38) es sorprendentemente bajo si lo comparamos con el número de especies que se consideran introducidas en el mar Mediterráneo, y representa apenas un 1,5 % del total, lo que apoya la idea de que un alto número de especies nativas tiende a reducir el éxito de las invasiones. La lista de especies que aquí se presenta constituye una herramienta muy necesaria para la identificación de áreas prioritarias de conservación de la biodiversidad, pero requiere una constante atención y actualización

An analysis of the variables that provide a supply chain with sustainable competitiveness

Objeto: Una cadena de suministro (CS) ágil, adaptable y alineada (Triple A) parece clave para la obtención de ventajas competitivas sostenibles. Sin embargo, hay escasa investigación previa sobre el tema, observándose incluso discrepancias a nivel conceptual. Por ello, el objetivo del presente trabajo es proponer un marco de referencia que determine las dimensiones y factores que definen la agilidad, adaptabilidad y alineación en la CS y facilite a los gestores e investigadores la evaluación del estado de la misma en lo que respecta a estas variables, así como el desarrollo de investigaciones empíricas que determinen su impacto en el rendimiento. Diseño/metodología/enfoque: Se realiza una revisión sistemática de bibliografía en revistas especializadas en Dirección de Operaciones, Logística, Administración y Gestión de la Cadena de Suministro utilizando la base de datos ABI/Inform. Los artículos obtenidos fueron revisados, seleccionándose los relevantes para este estudio. Con ellos se realizó un análisis cualitativo que nos llevó a la consecución del objetivo planteado. Aportaciones y resultados: En la presente investigación se establecen y agrupan, por primera vez, las definiciones, dimensiones y factores de la triple A en la CS, ofreciendo un marco conceptual que apoyará a investigadores y gestores a evaluar el desempeño de la CS. Aunque los artículos que analizan alguna de estas variables van en aumento, siguen siendo escasos. La agilidad es la variable más estudiada, siendo la adaptabilidad la menos analizada. Limitaciones / implicaciones: Se propone un marco de referencia teórico para la triple A en la CS construido a partir de estudios previos que no evalúan de manera conjunta las tres variables. El modelo será analizado empíricamente en futuras investigaciones. Originalidad / Valor añadido: La escasez de trabajos sobre agilidad, adaptabilidad y alineación en la CS, así como la falta de consenso respecto a las dimensiones y factores que las definen, hacen necesarios estudios como el que se presenta.Purpose: An agile, adaptable and aligned (Triple A) supply chain (SC) would seem to be key to obtaining sustainable competitive advantages. Little previous research has been done into the topic, however, and there are even discrepancies on the conceptual level. For this reason this study aims to propose a reference framework to determine the dimensions and factors that define agility, adaptability and alignment in the SC and to facilitate both the evaluation of its state by managers and researchers with respect to these variables and also the development of empirical research that determines its impact on performance. Design/methodology: A systematic literature review was carried out of specialist Operations Management, Logistics, Management and Supply Chain Management journals using the ProQuest (Abi/Inform Global) database. The articles retrieved were examined and those that were relevant for this study were selected. Using these, a qualitative analysis was done that led to the proposed goal being achieved. Findings: This study sets out the definitions, dimensions and factors of the three variables and groups them together for the first time, thus providing a solid conceptual frame. Although the number of articles that analyse one or other of the variables is growing, it is still low. Agility is the variable on which most research has been done, while adaptability is the least analysed. Research limitations/implications: A theoretical reference framework is proposed for the Triple A in the SC based on earlier studies which do not discuss the joint effect of three variables, as a result of which there is no tested theoretical base. The model will be analysed empirically in future research. Originality/value: The lack of papers on agility, adaptability and alignment in the supply chain and the lack of a consensus regarding the dimensions and factors to define them reveal a need for studies such as this.Peer Reviewe

An Analytical Model for Estimating the Delay in Bluetooth Communications with Serial Port Profile

Bluetooth is currently a major technology for the deployment of wireless short range communications. This paper presents an ana-lytical model to compute the delay of Bluetooth transmissions with Serial Port Profile (SPP), which is nowadays widely utilized by commercial Bluetooth-enabled devices. In particular, the pro-posed equations permit to estimate the packet delay in ideal transmission conditions (when no retransmission occurs) and also when environmental noise induces losses and consequently there exist a certain probability that a packet has to be retransmitted. The model takes into consideration the overhead and segmenta-tion introduced by the protocols involved in the transmission as well as the extra delay introduced by the retransmissions. The model has been empirically validated through the measurements of Bluetooth connections in an actual test-bed.Ministerio de Educación y Ciencia TEC2006-12211-C02-0

Analysis of Bluetooth Transmission Delay in Personal Area Networks

Bluetooth is by far the most employed technology to develop practical applications of Wireless Personal Area Networks (WPAN). This paper studies the performance of Bluetooth transmissions that make use of the Bluetooth PAN (Personal Area Network) profile. In particular, the study offers an analytical model that defines the optimal bound for the end-to-end data delay. The proposed ‘delay budget’ takes into account the overhead and segmentation provoked by the protocols involved in the transmission of user data. The model is empirically validated by comparing its results with those obtained through the measurements of actual Bluetooh connections.Ministerio de Educación y Ciencia TEC2006-12211-C02-0

Development and Evaluation of a Python Telecare System Based on a Bluetooth Body Area Network

This paper presents a prototype of a telemonitoring system, based on a BAN (Body Area Network) that is integrated by a Bluetooth (BT) pulse oximeter, a GPS (Global Positioning System) unit, and a smartphone. The smartphone is the hardware platformfor running a Python software thatmanages the Bluetooth piconet formed by the sensors. Thus the smartphone forwards the data received from the Bluetooth devices, encoded into JSON (JavaScript Object Notation), to a central server. This server provides universal access to the information of the patient’s location and health status through a web application based on AJAX (Asynchronous JavaScript and XML) technology. Additionally, for the described prototype, the study presents some performance analyses about several topics that are of great interest for the applicability of the prototype: (i) the technique used to forward the patient’s location and health status, (ii) the power consumption of the smartphone (which is compared with the measurements of an equivalent software developed for Java Micro Edition platform), and (iii) the web browser compatibility of the web application developed for the control and monitoring of the patients.Ministerio de Educación y Ciencia TEC2009-13763-C02-0

Overhead and Segmentation Mismatch Effect on Bluetooth WPAN Performance

Currently, Bluetooth is the most widely used technology for Wireless Personal Area Networks (WPAN). Quality-of-Service (QoS) support is critical to ensure bandwidth maximization for mobile applications based on this WPAN technology. The overhead introduced by the different layers of Bluetooth protocol may have a serious impact on WPAN performance. However, most studies of Bluetooth performance neglect this overhead and assume that data are directly transmitted over L2CAP (Logical Link Control and Adaptation Protocol) or even HCI (Host Controller Interface) layers. In fact, this option is not feasible in most Bluetooth applications, as they integrate actual devices that implement a particular Bluetooth profile, usually SPP (Serial Port Profile). The use of profiles cannot be disregarded as they guarantee the interoperability between devices from different vendors. The aim of this paper is to characterise the performance of a Bluetooth WPAN (specifically the end-to-end delay and the throughput) when profiles are utilised. This study takes into account the overhead added by the protocols taking part in the transmission of user data. This paper also explores the effect of segmentation mismatch that may appear when the maximum size for data in each layer of the architecture is different. The analysis has been focused on SPP and PAN (Personal Area Networks) profiles. In the case of the PAN profile, the study concludes that the network performance decreases for user data sizes greater than 1,472 bytes, since the excessive overhead added by the network layer is increased by the IP (Internet Proto-col) fragmentation. In the case of SPP, an inappropriate choice of the maximum data unit at RFCOMM (Radio Frequency Communication for Serial Cable Emulation Protocol based on ETSI TS 07.10) and L2CAP layers can also heavily affect the transmission delay
