The problem of automatically extracting novel and interesting knowledge from large amount of data is often performed heuristically when pattern extraction through classical statistical methods is found hard. In this paper an evolutionary approach, based on Differential Evolution, is proposed, which is able to perform the automatic discovery of comprehensible classification rules as a set of IF...THEN rules over a database of Multiple Sclerosis potential lesions. Moreover, this tool also determines which the most discriminant database attributes are in categorizing instances. Therefore, this evolutionary tool provides an efficient decision support system for clinical decisions, that could be a useful tool for medical experts to help them gain insight into the reasons for assessing the abnormality of a lesion.

Long Term Evolution (LTE) networks are expected to provide enhanced quality of service (QoS) guaranteed services and a high capacity. In this paper, we propose a novel QoS guaranteed cross-layer scheduling algorithm for LTE system. In fact the LTE scheduler is responsible for efficiently allocating the radio resources among mobile users who have different QoS demands. We focus on the resource blocks allocation and the Medium Access Control (MAC) scheduling algorithm. Our study highlights the impact of the Radio Resource Control (RRC) configuration on the overall performance and the Transport Block (TB) filling during the allocation process. Performance results show that the proposed algorithm is effective in enhancing service fairness, throughput and resource optimization. Our proposal aims to find an agreement between fairness, resource availability, the requested rate and service QoS requirements.

Resource provisioning and task scheduling in Cloud environments are quite challenging because of the fluctuating workload patterns and of the unpredictable behaviors and unstable performance of the infrastructure. It is therefore important to properly master the uncertainties associated with Cloud workloads and infrastructure. In this paper, we propose a probabilistic approach for resource provisioning and task scheduling that allows users to estimate in advance, i.e., offline, the resources to be provisioned, thus reducing the risk and the impact of overprovisioning or underprovisioning. In particular, we formulate an optimization problem whose objective is to identify scheduling plans that minimize the overall monetary cost for leasing Cloud resources subject to some workload constraints. This cost-aware model ensures that the execution time of an application does not exceed with a given probability a specified deadline, even in presence of uncertainties. To evaluate the behavior and sensitivity to uncertainties of the proposed approach, we simulate a simple batch workload consisting of MapReduce jobs. The experimental results show that, despite the provisioning and scheduling approaches that do not take into account the uncertainties in their decision process, our probabilistic approach nicely adapts to workload and Cloud uncertainties.

Health care practices increasingly rely on complex technological infrastructure, and new approaches to the integration of information and communication technology in those practices lead to the development of such concepts as integrated clinical environments and smart intensive care units. These concepts refer to hospital settings where therapy relies heavily on inter-operating medical devices, supervised by clinicians assisted by advanced monitoring and co-ordinating software. In order to ensure safety and effectiveness of patient care, it is necessary to specify the requirements of such socio-technical systems in the most rigorous and precise way. This paper presents an approach to the formalization of system requirements for communication networks deployed in integrated clinical environment, based on the higher-order logic language of a theorem-proving environment, the Prototype Verification System.

High expectations are tied to the millimeter wave (mmWave) technology and device to device (D2D) communications to leverage the capacity and the spectrum efficiency in 5th generation (5G) systems. In this context, we carry out a resource allocation scheme designed to enable D2D communications underlay cellular network in the E-band. The proposed scheme aims to enhance the system throughput and alleviate the interference caused by dense networks of D2D pairs that share and reuse the same resource blocks of cellular users. We provide a formulation of the optimization problem and indicate its NP-hardness. A great deal of merit is given to our resource re-use solution as it managed to increase the overall system throughput and it achieved significant results in mitigating the interference. Moreover, we shed light on how the system evolves when the transmit powers of both user terminals and device terminals increases.

Software Defined Networking (SDN) is considered one of the major driving factors to bring radical changes on Mobile Core Networks (MCN) design. There are many proposals on how to advocate SDN methodology, however, most of them stop at “vision” level without providing details about key performance contributors. In this paper, we tackle this gap and present a study of latency in SDN based MCN. We identify the major factors and elements in an SDN MCN that contribute to the overall latency. Two types of latency are considered: the processing delay inside the SDN control plane and the transmission delay of SDN control messages between controller and the managed switches. We use a realistic system setup with implementations of SDN controller and SDN application, as well as in-band transfer of control messages among switches and controller. We compare the latency obtained from SDN based MCN with the Evolved Packet Core (EPC). The observed overall latency in our experiments for SDN based MCN is within the EPC requirements. The direct comparison of the SDN versus EPC based MCN in the proposed scenarios show the first can reduce the overall latency. We also identified that the calls to controller APIs can be the major key contributors to the overall latency in SDN MCN, but the act of transmitting more control messages from the controller to the switches to setup longer flowpaths is not a key contributor for the overall latency.

In recent years we have been witnessing significant advances in the medical imaging techniques. With respect to the past, current imaging processes enable physicians to reach higher precision level when it comes to diagnosing patients' diseases. Such a precision is supported by sophisticated imaging machinery, whose cost increases with the technological advances. Also, most of imaging scans expose patients to ionizing radiation which in certain cases may seriously harm their health. In this panorama, ordering inappropriate imaging examinations has a great impact on both the economy of a nation and on its citizens' health. Many governments have published guidelines which physicians should follow when deciding which imaging technique is to be prescribed to best answer to a clinical question. The COLLABORADI project is a recently concluded research project which studied the phenomenon of inappropriate imaging prescriptions in Sicily (Italy), and proposed the design and implementation of a decision support system to help physicians to set up the most appropriate diagnostic route for their patients. This paper discusses the work carried out within the project.

Statistical authorities promote and safeguard the production and publication of official statistics that serve the public good. One of their duties is to monitor the presence of individuals region by region. Traditionally this activity has been conducted by means of censuses and surveys. Nowadays technologies open new possibilities such as a continuous sensing of the presences by leveraging the data associated to mobile devices, e.g., the behaviour of users on doing calls. In this paper first we propose a specifically conceived similarity function able to capture similarity between individuals call behaviours. Second we make use of a clustering algorithm able to handle arbitrary metric leading to a good internal and external consistency of clusters. The approach provides better population estimation with respect to state of the art comparing with real census data. The scalability and flexibility that characterises the proposed framework enables novel scenarios for the characterization of people by means of data derived from mobile users, ranging from the nearly-realtime estimation of presences to the definition of complex, uncommon user archetypes.

Within social media we find many stories that tell us the world that is around us. Unfortunately, we tend to forget what happened in the past and the young generations are losing a cultural heritage passed down for generations. In the attempt of preserving memories and of intercepting the attention of the new generations, in this paper we propose PlayTheCityRE, a location-based storytelling system that merges private film memories shot from 1940 to 1989 (e.g., 8mm, super8mm) with modern communication technologies to tell the story of our past while walking in city streets. The system is provided with a mobile application that allows people to explore an unusual city through the eyes of amateur film sequences (now historic) and to select different routes that will bring them in the same city places where they were filmed. By merging film memories with modern technologies, our system engages different audiences in specific ways and on multiple levels, allowing them to walk through history. Therefore, our storytelling system may help fostering historical consciousness within our society.

In this paper, we designed, implemented, and evaluated the performance of software OpenFlow flow counters in a bare metal commodity switch. Normally, flow counters are implemented in hardware for line-rate operations and their number needs to be very large to support a large flow-based SDN network. Although these hardware counters operate very fast, they greatly increase the cost of an OpenFlow switch. In addition, due to the limited chip size of the switching ASIC used in an OpenFlow switch, the number of hardware counters cannot scale to a large number. To overcome these drawbacks, we designed and implemented software flow counters in a 48 port × 10 Gbps (port bandwidth) bare metal commodity switch and evaluated their performance and limitations. This paper also reports important findings obtained from this practical work.
