Enterprise Integration of Smart Objects using Semantic Service Descriptions

Integrating physical objects (smart objects) and enterprise IT systems is still a labor intensive, mainly manual task done by domain experts. On one hand, enterprise IT backend systems are based on service oriented architectures (SOA) and driven by business rule engines or business process execution engines. Smart objects on the other hand are often programmed at very low levels. In this paper we describe an approach that makes the integration of smart objects with such backends systems easier. We introduce semantic endpoint descriptions based on Linked USDL. Furthermore, we show how different communication patterns can be integrated into these endpoint descriptions. The strength of our endpoint descriptions is that they can be used to automatically create REST or SOAP endpoints for enterprise systems, even if which they are not able to talk to the smart objects directly. We evaluate our proposed solution with CoAP, UDP and 6LoWPAN, as we anticipate the industry converge towards these standards. Nonetheless, our approach also allows easy integration with backend systems, even if no standardized protocol is used.

User and Machine Authentication and Authorization Infrastructure for Distributed Wireless Sensor Network Testbeds

The intention of an authentication and authorization infrastructure (AAI) is to simplify and unify access to different web resources. With a single login, a user can access web applications at multiple organizations. The Shibboleth authentication and authorization infrastructure is a standards-based, open source software package for web single sign-on (SSO) across or within organizational boundaries. It allows service providers to make fine-grained authorization decisions for individual access of protected online resources. The Shibboleth system is a widely used AAI, but only supports protection of browser-based web resources. We have implemented a Shibboleth AAI extension to protect web services using Simple Object Access Protocol (SOAP). Besides user authentication for browser-based web resources, this extension also provides user and machine authentication for web service-based resources. Although implemented for a Shibboleth AAI, the architecture can be easily adapted to other AAIs.

The relationship between enterotoxigenic {\it Escherichia coli\/} infection and environmental risk factors in Bilbeis, Egypt, 1981--1983

Diarrheal disease associated with enterotoxigenic Escherichia coli (ETEC) infection is one of the major public health problems in many developing countries, especially in infants and young children. Because tests suitable for field laboratories have been developed only relatively recently, the literature on the environmental risk factors associated with ETEC is not as complete as for many other pathogens or for diarrhea of unspecified etiology.^ Data from a diarrheal disease surveillance project in rural Egypt in which stool samples were tested for a variety of pathogens, and in which an environmental questionnaire was completed for the same study households, provided an opportunity to test for an association between ETEC and various risk factors present in those households. ETEC laboratory-positive specimens were compared with ETEC laboratory-negative specimens for both symptomatic and asymptomatic children less than three years of age at the individual and household level using a case-comparison design.^ Individual children more likely to have LT infection were those who lived in HHs that had cooked food stored for subsequent consumption at the time of the visit, where caretakers used water but not soap to clean an infant after a diarrheal stool, and that had an indoor, private water source. LT was more common in HHs where the caretaker did not clean an infant with soap after a diarrheal stool, and where a sleeping infant was not covered with a net. At both the individual and HH level, LT was significantly associated with good water supply in terms of quantity and storage.^ ST was isolated more frequently at the individual level where a sleeping infant was covered with a net, where large animals were kept in or around the house, where water was always available and was not potable, and where the water container was not covered. At the HH level, the absence of a toilet or latrine and the indiscriminate disposal of animal waste decreased risk. Using animal feces for fertilizer, the presence of large animals, and poor water quality were associated with ST at both the individual and HH level.^ These findings are mostly consistent with those of other studies, and/or are biologically plausible, with the obvious exception of those from this study where poorer water supplies are associated with less infection, at least in the case of LT. More direct observation of how animal ownership and feces disposal relates to different types of water supply and usage might clarify mechanisms through which some ETEC infection could be prevented in similar settings. ^

Arthropoda abundance along an elevation gradient on the southern slopes of Mount Kilimanjaro, Tanzania

Species diversity is the most common variable reported in recent ecological research articles. Ecological processes, however, are driven by individuals. High abundances make arthropods, despite their small body sizes, important actors in food webs. We sampled arthropod assemblages in disturbed and undisturbed vegetation types along an elevation gradient of from 800 to 4550 m a.s.l. on the southern slopes of Mt. Kilimanjaro, Tanzania. In our analysis, we focused on 13 different lineages of arthropods that represented three major functional groups: predators, herbivores and decomposers. The samples were collected with pitfall traps on 59 (of 60) study sites within the framework of the KiLi-project (https://www.kilimanjaro.biozentrum.uni-wuerzburg.de/). In each of twelve vegetation types five sampling sites of 50 m x 50 m were established with a minimum distance of 300 m between the individual sites. On each of the 59 sites, ten pitfall traps were evenly spaced along two 50 m transects, with a distance of 10 m between individual traps and 20 m between the parallel transects. Pitfall traps were filled with 100-200 ml of a mixture of ethylenglycol and water (1:1) with a drop of liquid soap to break surface tension. Traps were exposed at 2 to 5 sampling events for seven days in both the dry and wet seasons between May 2011 and October 2012. The reported abundances per lineage were averaged twice: first over all samples per site for each sampling event (3-10 analyzed samples per site and sampling event), and then averaged over all sampling events for each site.

Android en el Hogar Digital usando UPnP y Redes LonWorks

Este Proyecto Final de Carrera se centra principalmente en el estudio de las tecnologías aplicadas al Hogar Digital (HD) y así poder desarrollar nuevas herramientas aplicadas a este Sector. La primera tecnología estudiada es LonWorks que se escogió porque en la EUITT se cuenta con un entorno domótico donde se aplica esta tecnología, materializado como una maqueta de una instalación LonWorks en un HD. Sobre este entorno se ha desarrollado una nueva forma de gestionar y controlar los elementos de una Red LonWorks mediante la tecnología Universal Plug & Play (UPnP). Los dispositivos LonWorks han sido recubiertos con una capa con la que se consigue tratar los elementos LonWorks como dispositivos UPnP, pudiendo de esta manera trabajar bajo un mismo formato de dispositivo. Este formato está definido por un documento denominado Descripción del Dispositivo UPnP. Por tanto, no es necesario conocer el estado de los dispositivos de la Red LonWorks, sino únicamente trabajar bajo una Red UPnP, creando nuevos dispositivos UPnP, puntos de Control y servicios a partir de los elementos LonWorks. Una vez realizado el recubrimiento del sistema LonWorks con UPnP, se ha definido y desarrollado una aplicación para Android que, permite controlar los elementos de la maqueta del HD desde un Smartphone o una Tablet. El acceso a la Red LonWorks de la maqueta del HD se hace a través de la interfaz Web Services SOAP/XML del dispositivo iLON100. ABSTRACT. This Final Degree Project is mainly focused on the study of the technologies applied to Digital Home and thus be able to develop new tools applied to this area. The first study is LonWorks technology which was chosen because the EUITT has a domotic environment where this technology is applied, materialized as a demonstrator of a LonWorks installation in HD. With this environment has developed a new way to manage and control the elements of a LonWorks network through technology by Universal Plug & Play (UPnP). LonWorks devices are covered with a layer and it is achieved LonWorks elements treat as UPnP devices. In this way the LonWorks elements can work under one device format. This format is defined by a document called UPnP Device Description. Therefore, it isn't necessary to know the state of the LonWorks network devices, but only work under an UPnP network, creating new UPnP devices, control points and services from LonWorks elements. After backfill of LonWorks system with UPnP, have being defined and developed an Android application that allow controlling the elements of the mockup of HD from Smartphone or a Tablet. The LonWorks network Access of the mockup of HD is done through the Web Interface Services SOAP / XML iLON100 device.

Seven challenges for RESTful transaction models

The REpresentational State Transfer (REST) architectural style describes the design principles that made the World Wide Web scalable and the same principles can be applied in enterprise context to do loosely coupled and scalable application integration. In recent years, RESTful services are gaining traction in the industry and are commonly used as a simpler alternative to SOAP Web Services. However, one of the main drawbacks of RESTful services is the lack of standard mechanisms to support advanced quality-ofservice requirements that are common to enterprises. Transaction processing is one of the essential features of enterprise information systems and several transaction models have been proposed in the past years to fulfill the gap of transaction processing in RESTful services. The goal of this paper is to analyze the state-of-the-art RESTful transaction models and identify the current challenges.
