Mediación penal: contribución a la simplificación del proceso y la resocialización del delincuente. Posibilidades de implementación en Cuba

The intention of this investigation is to build theoretically the relevance of the criminal mediation as a simplifier mechanism of the process and its contribution to the resocialization of the criminal, aspects that certainly constitute added values to the criminal mediation process, although they are not exalted in the way they deserve. On the contrary, frequently to cover the topic criminal mediation is granted major effort to the corresponding process offered to the victims, without taking into account the simplifier character to the process, which results trascendentalfor judges can emply their time to the more complex cases. On the other hand, it is alluded in matter to criminal mediation and its contribution to criminal resocialization not only because the medition will be a properly a synonym of resocialization but also to avoid the imposition of a criminal sanction, undoubtedly the criminal will free from a sanction and its stigmatizing effects, what it favors an appropriate resocialization process. It is about an investigation of theoretical character, for this reason, the methodology used is according to this. The elements that will be developed corresponding to the theory allow to question if it is feasible to implement the criminal mediation in Cuba, reflection which is finished our work.It is concluded that is not only to implement the criminal mediation in Cuba, but also it constitutes a current need in the Caribean country.El objetivo de esta investigación es fundamentar teóricamente la pertinencia de la mediación penal como mecanismo simplificador del proceso y su contribución a la resocialización del delincuente, aspectos que sin duda constituyen valores agregados de los procesos de mediación penal, aunque no son enaltecidos de la forma que merecen.Por el contrario, frecuentemente al abordarse el tema de la mediación penal se le otorga mayor fuerza a lo que dicho proceso le ofrece a las víctimas, obviándose en cierta medida el carácter simplificador del proceso, lo cual resulta trascendente para que los jueces puedan dedicar su tiempo a los casos más complejos; y por otra parte,  también se alude en materia de mediación penal a su contribución a la resocialización del delincuente, no porque la mediación propiamente sea sinónimo de resocialización, sino porque al evitar la imposición de una sanción penal, sin dudas se estará librando al delincuente de una sanción y sus efectos estigmatizantes, lo cual favorece un mejor proceso de resocialización. Se trata de una investigación de carácter teórico, por tanto, la metodología utilizada se corresponde con ello. Los elementos que se desarrollan con arreglo a la teoría permiten cuestionarse si resulta posible implementar la mediación penal en Cuba, reflexión con la que culminamos nuestro trabajo. Se concluye que no solo puede implementarse la mediación penal en Cuba, sino que también constituye una necesidad actual en el país caribeño

Single-Board-Computer Clusters for Cloudlet Computing in Internet of Things

The number of connected sensors and devices is expected to increase to billions in the near future. However, centralised cloud-computing data centres present various challenges to meet the requirements inherent to Internet of Things (IoT) workloads, such as low latency, high throughput and bandwidth constraints. Edge computing is becoming the standard computing paradigm for latency-sensitive real-time IoT workloads, since it addresses the aforementioned limitations related to centralised cloud-computing models. Such a paradigm relies on bringing computation close to the source of data, which presents serious operational challenges for large-scale cloud-computing providers. In this work, we present an architecture composed of low-cost Single-Board-Computer clusters near to data sources, and centralised cloud-computing data centres. The proposed cost-efficient model may be employed as an alternative to fog computing to meet real-time IoT workload requirements while keeping scalability. We include an extensive empirical analysis to assess the suitability of single-board-computer clusters as cost-effective edge-computing micro data centres. Additionally, we compare the proposed architecture with traditional cloudlet and cloud architectures, and evaluate them through extensive simulation. We finally show that acquisition costs can be drastically reduced while keeping performance levels in data-intensive IoT use cases.Ministerio de Economía y Competitividad TIN2017-82113-C2-1-RMinisterio de Economía y Competitividad RTI2018-098062-A-I00European Union’s Horizon 2020 No. 754489Science Foundation Ireland grant 13/RC/209

Bonding to silicate ceramics : conventional technique compared with a simplified technique

Silicate ceramic bonding is carried out by acid-etching with hydrofluoric acid (HF) followed by an application of silane. By replacing HF with ammonium polyfluoride, contained in the same flask as the silane, the number of steps in this clinical procedure, can be reduced, while maintaining bond strength values, and reducing toxicity. A shear bond test was performed to compare the conventional and the simplified surface treatment techniques. Twenty ceramic samples were fabricated from IPS emax CAD® ceramic (Ivoclar Vivadent) and divided into two groups (G1 and G2) (n=10). The conventional technique was applied to G1 samples, and the simplified technique to G2 samples. A resin cement cylinder was bonded to each sample. Afterwards, samples underwent shear bond strength testing in a universal test machine. G1 obtained 26.53±6.33 MPa and G2 23.52±8.41 MPa, without statistically significant differences between the two groups. Monobond Etch Prime appears to obtain equivalent results in terms of bond strength while simplifying the technique. Further investigation is required to corroborate these preliminary findings

On-site forest fire smoke detection by low-power autonomous vision sensor

Early detection plays a crucial role to prevent forest fires from spreading. Wireless vision sensor networks deployed throughout high-risk areas can perform fine-grained surveillance and thereby very early detection and precise location of forest fires. One of the fundamental requirements that need to be met at the network nodes is reliable low-power on-site image processing. It greatly simplifies the communication infrastructure of the network as only alarm signals instead of complete images are transmitted, anticipating thus a very competitive cost. As a first approximation to fulfill such a requirement, this paper reports the results achieved from field tests carried out in collaboration with the Andalusian Fire-Fighting Service (INFOCA). Two controlled burns of forest debris were realized (www.youtube.com/user/vmoteProject). Smoke was successfully detected on-site by the EyeRISTM v1.2, a general-purpose autonomous vision system, built by AnaFocus Ltd., in which a vision algorithm was programmed. No false alarm was triggered despite the significant motion other than smoke present in the scene. Finally, as a further step, we describe the preliminary laboratory results obtained from a prototype vision chip which implements, at very low energy cost, some image processing primitives oriented to environmental monitoring.Ministerio de Ciencia e Innovación 2006-TIC-2352, TEC2009-1181

Focal-plane generation of multi-resolution and multi-scale image representation for low-power vision applications

Early vision stages represent a considerably heavy computational load. A huge amount of data needs to be processed under strict timing and power requirements. Conventional architectures usually fail to adhere to the specifications in many application fields, especially when autonomous vision-enabled devices are to be implemented, like in lightweight UAVs, robotics or wireless sensor networks. A bioinspired architectural approach can be employed consisting of a hierarchical division of the processing chain, conveying the highest computational demand to the focal plane. There, distributed processing elements, concurrent with the photosensitive devices, influence the image capture and generate a pre-processed representation of the scene where only the information of interest for subsequent stages remains. These focal-plane operators are implemented by analog building blocks, which may individually be a little imprecise, but as a whole render the appropriate image processing very efficiently. As a proof of concept, we have developed a 176x144-pixel smart CMOS imager that delivers lighter but enriched representations of the scene. Each pixel of the array contains a photosensor and some switches and weighted paths allowing reconfigurable resolution and spatial filtering. An energy-based image representation is also supported. These functionalities greatly simplify the operation of the subsequent digital processor implementing the high level logic of the vision algorithm. The resulting figures, 5.6m W@30fps, permit the integration of the smart image sensor with a wireless interface module (Imote2 from Memsic Corp.) for the development of vision-enabled WSN applications.Junta de Andalucía 2006-TIC-2352Ministerio de Ciencia e Innovación TEC 2009-11812Office of Naval Research (USA) N00014111031
