A First Step Towards Automatically Building Network Representations

To fully harness Grids, users or middlewares must have some knowledge on the topology of the platform interconnection network. As such knowledge is usually not available, one must uses tools which automatically build a topological network model through some measurements. In this article, we define a methodology to assess the quality of these network model building tools, and we apply this methodology to representatives of the main classes of model builders and to two new algorithms. We show that none of the main existing techniques build models that enable to accurately predict the running time of simple application kernels for actual platforms. However some of the new algorithms we propose give excellent results in a wide range of situations

Passive solar component for building renovation strategy to synergize building systems and increase energy efficiency in Barcelona

This Master’s Thesis looks into the relationship between architecture and the environment, focusing on the city of Barcelona. It aims to rebuild a connection that has been lost by proposing a passive solar component to be added to the facade of existing buildings. This component acts as a solar chimney in the summer, enhancing natural ventilation through the stack effect, and a Trombe wall in the winter providing indirect solar heat gain. The incorporation of phase change materials to address the limitation of non-operative conditions when solar energy is not available is also proposed

An intelligent radio access network selection and optimisation system in heterogeneous communication environments

PhDThe overlapping of the different wireless network technologies creates heterogeneous communication environments. Future mobile communication system considers the technological and operational services of heterogeneous communication environments. Based on its packet switched core, the access to future mobile communication system will not be restricted to the mobile cellular networks but may be via other wireless or even wired technologies. Such universal access can enable service convergence, joint resource management, and adaptive quality of service. However, in order to realise the universal access, there are still many pending challenges to solve. One of them is the selection of the most appropriate radio access network. Previous work on the network selection has concentrated on serving the requesting user, but the existing users and the consumption of the network resources were not the main focus. Such network selection decision might only be able to benefit a limited number of users while the satisfaction levels of some users are compromised, and the network resources might be consumed in an ineffective way. Solutions are needed to handle the radio access network selection in a manner that both of the satisfaction levels of all users and the network resource consumption are considered. This thesis proposes an intelligent radio access network selection and optimisation system. The work in this thesis includes the proposal of an architecture for the radio access network selection and optimisation system and the creation of novel adaptive algorithms that are employed by the network selection system. The proposed algorithms solve the limitations of previous work and adaptively optimise network resource consumption and implement different policies to cope with different scenarios, network conditions, and aims of operators. Furthermore, this thesis also presents novel network resource availability evaluation models. The proposed models study the physical principles of the considered radio access network and avoid employing assumptions which are too stringent abstractions of real network scenarios. They enable the implementation of call level simulations for the comparison and evaluation of the performance of the network selection and optimisation algorithms

Reusing Deep Neural Network Models through Model Re-engineering

Training deep neural network (DNN) models, which has become an important task in today's software development, is often costly in terms of computational resources and time. With the inspiration of software reuse, building DNN models through reusing existing ones has gained increasing attention recently. Prior approaches to DNN model reuse have two main limitations: 1) reusing the entire model, while only a small part of the model's functionalities (labels) are required, would cause much overhead (e.g., computational and time costs for inference), and 2) model reuse would inherit the defects and weaknesses of the reused model, and hence put the new system under threats of security attack. To solve the above problem, we propose SeaM, a tool that re-engineers a trained DNN model to improve its reusability. Specifically, given a target problem and a trained model, SeaM utilizes a gradient-based search method to search for the model's weights that are relevant to the target problem. The re-engineered model that only retains the relevant weights is then reused to solve the target problem. Evaluation results on widely-used models show that the re-engineered models produced by SeaM only contain 10.11% weights of the original models, resulting 42.41% reduction in terms of inference time. For the target problem, the re-engineered models even outperform the original models in classification accuracy by 5.85%. Moreover, reusing the re-engineered models inherits an average of 57% fewer defects than reusing the entire model. We believe our approach to reducing reuse overhead and defect inheritance is one important step forward for practical model reuse.Comment: Accepted by ICSE'2

Barcos calcolíticos (c. 2500/2000 BC) del Mediterráneo occidental.

En este artículo se hace el estudio de un grafito barquiforme inciso en un cuenco campaniforme procedente del poblado de Los Millares. Se interpreta como una representación de barcas complejas de base monóxila. Son conocidos materiales del Calcolítico ibérico en el norte de África, así como marfil y huevos de avestruz en asentamientos peninsulares; sin embargo, se ignoraba hasta ahora la naturaleza de las barcas que hicieron posibles estas travesías. El yacimiento epicardial de las islas Chafarinas parece indicar que estas conexiones pudieron comenzar ya en el V milenio BC.This article studies a boat-shaped graffito incised on a bell-beaker earthen bowl from the town of Los Millares, which has been interpreted as a depiction of complex monoxil, or single dugout trunk-based boats, a type well-known in North Africa during the Iberian Chalcolithic period, as were ivory and ostrich eggs in settlements in the Iberian Peninsula. Nevertheless, the nature of the boats that made these passages possible was unknown until now. The epicardial site of the Chafarinas Islands seems to indicate that these connections may have already commenced in the fifth millennium BC.En este artículo se hace el estudio de un grafito barquiforme inciso en un cuenco campaniforme procedente del poblado de Los Millares.

The new services in nagios network bandwidth utility email notification and sms alert in improving the network performance

A new feature of services in Nagios has been added to the existing system which has no such services. The bandwidth monitoring and notification system are configured for alerting the network administrators when the bandwidth of the network in an organization hits a certain threshold settings. The system sent an email alert and sms notification to the network administrator for taking further action in order to maintain the Quality of Service (QoS) in the network. All the logs file of the Nagios actions is saved in the Nagios File Logs. The analysis was conducted from the case study and problem statements. Network Development Life Cycle (NDLC) was chosen as a methodology for implementing this system in the network. Nagios is installed inside Ubuntu 10 Operating System along with Multi-Router Traffic Grapher (MRTG) and Mail Postfix. MRTG and Mail Postfix were configured to be integrated with the Nagios System. On the client side, NSClient++ has been installed, for monitoring the bandwidth and performance of windows based on operating system. The Nagios services have been improved with the implementation of sms and emails notifications since the existing services have no such utilities. With the implementation of these services to Nagios, the performance could be even better for the futur
