Abstract
With advances in communication technology, future internet presents numerous opportunities to develop new systems designed to make day to day life easier and to enhance and prolong the life of people with disabilities. This motivation propels the development of new services that integrate the mobility of cloud systems and the diversity of IoT (Internet of Things). It will enable us to create new and more independent care systems for people with disabilities, enabling a certain degree of independence. This can have a psychological and social impact due to the better quality of life that enables. Other motivation is the versatility and mobility of services it can provide, making those services available. In this paper is explored and explained the different kinds of technologies that can be integrated to enable creation of future internet platforms. Also, an IoT Cloud platform will be analyzed and some tests will be made, ending with some conclusions and lessons learned in this work.

Abstract
Software refactoring is a well-known technique that provides transformations on software artifacts with the aim of improving their overall quality. In this paper we present a set of refactorings for ClassSheets, a modeling language that allows to specify the business logic of a spreadsheet in an object-oriented fashion. The set of refactorings that we propose allows us to improve the quality of these spreadsheet models. Moreover, it is implemented in a setting that guarantees that all model refactorings are automatically carried to all the corresponding (spreadsheet) instances, thus providing an automatic evolution of the data so it is always synchronized with the model.

Abstract
The creative transition from understanding the customer experience to defining the service solution, from current situation to preferred future, is central to Service Design. However, the incorporation of customer experience factors can change along the different iterative cycles of service design. To address this challenge, this paper presents the results of a study of how the path of customer experience was followed, studied and incorporated along a mobile service development. Three iterative Service Design cycles enabled a holistic vision of the service and raised ‘customer experience’ awareness on the development team. Following a design research approach, experience factors were actively taken into account and incorporated along ideation and implementations cycles involving a total of 61 interviews. The research work contributes to Service Design by providing a global vision of the experiential changes, especially in mobile and technology based services. It describes the reframed situations working with experiences at each cycle of design, and making use of service design tools and methods at each moment.

Abstract
This work presented a demonstration of the potential for a fiber based cavity ring-down (CRD) using an optical time-domain reflectometer (OTDR). The OTDR was used to send the impulses down into about 20 km of a standard single optical fiber, at the end of which the fiber cavity ring-down was placed. The OTDR measured no appreciable losses, so other CRDs multiplexed could be spliced in parallel along the same optical fiber. To demonstrate the behavior and sensitivity of the proposed configuration, a displacement sensor based on a fiber taper with a diameter of 50 µm was placed inside the fiber loop, and the induced losses were measured on the CRD signal — a sensitivity of 11.8 ± 0.5 µs/mm was achieved. The dynamic range of the sensing head used in this configuration was about 2 mm. Finally, this work was also compared with different works published in the literature. © 2014, The Author(s).
