Concept Generation and Preliminary Prototyping of a Tailored Smart Glove with Capacitive Pressure Sensors for Force Grip Analysis in Cycling

Design methods for sports engineering allow to improve the world around the athlete. In cycling, a sport device that can be useful to reduce and monitor the risk of injuries is a smart glove equipped with pressure sensors. The literature underlined how the current design methods lack the comprehensive consideration of sensors integration for force analysis at the handlebar. Furthermore, the majority of existing solutions is based on resistive pressure sensors. In this work, we present mainly two advancements with respect to the state-of-the-art: (1) user-centered design methodology for the glove development, which allows to take care about the main design parameters which involve the cyclist, namely her/his anthropometric characteristics and her/his sport gesture analysis (achieved by the pressure analysis on the handlebar) during classic grip position of cycling (i.e., top grip); (2) prototyping of custom-made capacitive pressure sensors instead of classic commercial resistive pressure sensors. The work involves the concept generation, the selection of the optimal concept through Kano and Quality of Function Development as well as the preliminary prototyping of one capacitive pressure sensor, realized using a fabrication process involving additive manufacturing techniques and silicon molding

Analysis of coexistence and mutual interference between mobile and digital television systems

La creciente demanda de servicios de comunicaciones inalámbricas multimedia es un factor clave en los mercados más desarrollados. Así, las palabras de moda en las comunicaciones personales “acceso para cualquier persona, en cualquier sitio, en cualquier momento y para el servicio deseado”, implican una demanda notoria y creciente del Espectro Radioeléctrico. En este sentido, la última Conferencia Mundial de Radiocomunicaciones 2007 (CMR-07) atribuyó la parte alta de la banda UHF a las redes móviles como servicio co-primario a partir del 2015 en la Región 1, aprovechando el Dividendo Digital debido a la mayor eficiencia espectral de la TV digital con respecto a la analógica. Esto tiene el potencial de causar una interferencia perjudicial entre los sistemas de televisión y los sistemas móviles y necesita ser analizado con atención. En este artículo presentamos un estudio del problema de la interferencia co-canal en dicho escenario, proponiendo una metodología para tener en cuenta la interferencia entre una red móvil LTE y un sistema televisivo DVB-T, poniendo de relieve el comportamiento diferente de los dos radioenlaces.The ever increasing demand for multimedia wireless communication systems is a key feature of more advanced markets. The buzzwords of personal communications, meant to provide “access to anyone, anywhere, at anytime to the wanted service”, implies that radio spectrum demands are dramatically increasing in most developed markets. The last World Radiocommunication Conference (WRC-07) allocated on a co-primary basis the upper part of the UHF band to mobile services as from 2015 in Region 1, taking advantage of the Digital Dividend due to the higher spectrum efficiency of digital TV with respect to the analogue system. This will cause potentially harmful mutual interference between TV and mobile radio services, that needs to be carefully analysed. In this paper we present a study of the co-channel interference problem, proposing a methodology to take into account the mutual interference between a LTE mobile network and a DVB-T system and highlighting the different behaviour of the two radio links

A rare case of appendicular skeleton localization in a patient with chronic lymphocytic leukemia successfully treated with salvage radiation therapy

Bone involvements in chronic lymphocytic leukemia (CLL) are considered rare events, and the English-language medical literature describes them only in sporadic case reports. Consequently, robust indications for a rational clinical management are lacking. We report the case of a middle-aged man in clinical follow-up for CLL who experienced pain at the right tibial level that was refractory to nonsteroidal anti-inflammatory drugs and an acute episode of anemia. Instrumental examinations and a bioptic sample surprisingly demonstrated a bone tibial localization by CLL

Advances in Wireless Ad Hoc and Sensor Networks

Traditionally, until the end of 20-th century, wireless systems could be subdivided in three broad categories, namely point-to-point, point-to-multipoint and area systems. The three categories are rather distinct from each other. Point-to-point links are generally bidirectional and symmetrical, providing the same transmission capacity at both ends of the link, while the two terminals usually are identical. Point-to-multipoint systems, on the other hand, are intrinsically hierarchical, inasmuch as there is one central terminal which is in charge of communication with all the other peripheral terminals. The individual links can be either symmetrical or asymmetrical, and they can also be unidirectional. Finally, area systems (such as mobile radio and broadcasting) are characterised by one station providing service to all the terminals within its coverage area. Mobile radio links are generally bidirectional and they can be either symmetrical or asymmetrical depending from the application. On the contrary, broadcasting systems are intrinsically unidirectional, with the terminals only able to receive the signal emitted by the transmitter. Area systems in general may also support terminal mobility, allowing the terminal to interact with the central station from whichever location of the coverage area, and even to move among coverage areas of different stations. The development of new, advanced concepts and standards brought along distributed network architectures that can't be encompassed in the above taxonomy. The familiar one-to-one and one-to-many relationships cease to apply, and each terminal is immersed in a web-like network of similar elements, exchanging information and/or co-operating with each other. In this chapter we address some of the hottest topics related to the evolution of advanced wireless network systems and architectures. We start presenting the main contributions of COST 2100 to the theory of wireless networks. Then we present a thorough overview of activities regarding Wireless Sensors Networks and Mesh Networks, while the subsequent section deals with Cognitive Radio. Finally, the possibilities offered by MANET are discussed

Virtual Canova: a Digital Exhibition Across MANN and Hermitage Museums

The paper presents the results of a scientific collaboration between the Interdepartmental Research Center Urban/Eco of the University of Naples Federico II and the MANN (Museo Archeologico Nazionale di Napoli, National Archaeological Museum of Naples). The research activity was aimed to the digitisation, design, and development of an AR/VR-powered narrative experience regarding Antonio Canova’s statuary that is currently exhibited at the MANN, loaned by the Hermitage in St. Petersburg: Cupid, Hebe, Dancer, Cupid and Psyche, the Genius of Death and The Three Graces. The project is motivated by the will to realize an active example of a digital museum, where cultural and formative experiences related to the fruition of architectural and artistic artifacts can be relived over time, even when manufacts are not physically and/or temporally located in the space where the experience takes place

Copper (I) or (II) Replacement of the Structural Zinc Ion in the Prokaryotic Zinc Finger Ros Does Not Result in a Functional Domain

A strict interplay is known to involve copper and zinc in many cellular processes. For this reason, the results of copper’s interaction with zinc binding proteins are of great interest. For instance, copper interferences with the DNA-binding activity of zinc finger proteins are associated with the development of a variety of diseases. The biological impact of copper depends on the chemical properties of its two common oxidation states (Cu(I) and Cu(II)). In this framework, following the attention addressed to unveil the effect of metal ion replacement in zinc fingers and in zinc-containing proteins, we explore the effects of the Zn(II) to Cu(I) or Cu(II) replacement in the prokaryotic zinc finger domain. The prokaryotic zinc finger protein Ros, involved in the horizontal transfer of genes from A. tumefaciens to a host plant infected by it, belongs to a family of proteins, namely Ros/MucR, whose members have been recognized in different bacteria symbionts and pathogens of mammals and plants. Interestingly, the amino acids of the coordination sphere are poorly conserved in most of these proteins, although their sequence identity can be very high. In fact, some members of this family of proteins do not bind zinc or any other metal, but assume a 3D structure similar to that of Ros with the residues replacing the zinc ligands, forming a network of hydrogen bonds and hydrophobic interactions that surrogates the Zn-coordinating role. These peculiar features of the Ros ZF domain prompted us to study the metal ion replacement with ions that have different electronic configuration and ionic radius. The protein was intensely studied as a perfectly suited model of a metal-binding protein to study the effects of the metal ion replacement; it appeared to tolerate the Zn to Cd substitution, but not the replacement of the wildtype metal by Ni(II), Pb(II) and Hg(II). The structural characterization reported here gives a high-resolution description of the interaction of copper with Ros, demonstrating that copper, in both oxidation states, binds the protein, but the replacement does not give rise to a functional domain
