There are a number of reasons that encourage the use of open source software `OSS' such as: cost savings, fast time-to-market and high-quality software[1]. Various organizations have considered the use of free software in their IT infrastructure for economic, security or other reasons. With a large number of free software available on the internet, choosing the best one has become a daunting task. In order to solve this problem, different methods have been proposed. In this paper, we propose a new method to 'measure the maturity of free software' which is relevant and easy to be adopted especially for small and medium enterprises. To evaluate our approach, we tested it in more than twenty companies in order to choose the best free software that will meet their real needs.

The incorporation of security mechanisms to protect spacecraft's TT C and payload links is becoming a constant requirement in many space missions. More advanced mission concepts will allow spacecrafts to have higher levels of autonomy, which includes performing key management operations independently of control centers. This is especially beneficial to support missions operating distantly from Earth. In order to support such levels of autonomy, key agreement is one approach that allows spacecrafts to establish new cryptographic keys as they deem necessary. This work introduces an approach based on a trusted platform module that allows for key agreement to be performed with minimal computational efforts and protocol iterations. Besides, it allows for opportunistic control center reporting while avoiding man-in-the-middle and replay attacks.

We are now facing a new age of digital content industry caused by diffusion of wearable device. The Realistic content, which consists of virtual reality, augmented reality and hologram technologies. It had been predicted as the future digital content technology by many institutions and researchers. However, there were very limited researchers who tried to predict the possibility of realistic content by analysing the user acceptance of realistic content technology. To analyse the intention of user acceptance, factors from three different perspectives were integrated with technology acceptance model to improve the reliability and validity of the research model and to give better results of analysis. Survey had been conducted by users in South Korea(N=429) who aware the existence of realistic content technology. Analysis was made based on structural equation modeling(SEM) method. The result of factor analysis showed that Flow and Spatiality have significant influence to Perceived usefulness. Interaction and Display have significant influence to the Perceived ease of use. Meanwhile users pointed out the Privacy risk as the most significant risk that avoid users to use the realistic content.

Lasing threshold conditions have been analyzed in deep-UV (DUV) multiple-QW (MQW) III-nitride laser diode (LD) structures with different QW confinement depth. Shallow QWs with smaller internal polarization fields reveal better QW emission characteristics including lower QW transparency population and higher differential gain. In MQW LD structures, however, the high-gain operation of shallow QWs is hindered by insufficient QW injection due to increased carrier leakage from shallow-QW active region. Deep active QWs can attain higher operational populations and provide for higher LD optical gain; however, LDs designed with deeper active QWs suffer from MQW population non-uniformity due to increased inhomogeneity of carrier injection. Underpumped deep QWs reduce the total modal gain of the LD structure thus deteriorating the lasing threshold and LD power conversion (wall-plug) efficiency.

Core decomposition has been applied widely in the visualization and analysis of massive networks. However, existing studies of core decomposition were only limited to non-temporal graphs, while many real-world graphs can be naturally modeled as temporal graphs (e.g., the interaction between users at different time in online social networks, the phone call or messaging records between friends over time, etc.). In this paper, we define the problem of core decomposition in a temporal graph, propose efficient distributed algorithms to compute the cores in massive temporal graphs, and discuss how the technique can be used in temporal graph analysis.

The paper describes decomposition of natural join relational operator based on the column indices and domain-interval fragmentation. This decomposition admits parallel executing the resource-intensive relational operators without data transfers. All column index fragments are stored in main memory in compressed form to conserve space. During the parallel execution of relational operators, compressed index fragments are loaded on different processor cores. These cores unpack fragments, perform relational operator and compress fragments of partial result, which is a set of keys. Partial results are merged in the resulting set of keys. DBMS use the resulting set of keys for building the resulting table. Described approach allows efficient parallel query processing for very large databases on modern computing cluster systems with many-core accelerators. A prototype of the DBMS coprocessor system was implemented using this technique. The results of computational experiments are presented. These results confirm the efficiency of proposed approach.

The advantages of nanocomposites containing single silicate layers uniformly dispersed in a polymer matrix were first demonstrated by researchers at Toyota in Japan, who developed nylon-6 nanocomposites and published in 1993. Polymer-nanoclay nanocomposites have attracted the attention of many researchers thereafter due to their outstanding mechanical and barrier properties. This concept is first applied to synthesis of plastics/nanoclay nanocomposites and then expanded to preparation of rubber/nanoclay nanocomposites, since few years later. The various types of synthetic rubbers, such as silicon rubber, nitrile rubber and epoxy rubber, were used to prepare nanocomposites using different techniques, namely, melt intercalation, in situ intercalative polymerization, exfoliation-adsorption and template synthesis, etc. Natural rubber (NR) was also used to prepare nanocomposites using the same techniques but with some modifications in the last decade. Nowaday's nanocomposites are widely developed in NR latex industry to achieve required properties with minimum use of clay content. NR/nanoclay nanocomposites exhibit markedly improved properties when compared to pure NR or their traditional composites. Most notable properties are increased tensile properties, gas barrier properties and heat distortion temperature, resistance to small molecule permeation, increase in atomic oxygen resistance and retention of impact strength. Tensile strength and modulus were recorded in current research as enhanced by more than two times or even ten times. It was noticed that obtaining a fully exfoliated structure is not at the desired level. Nanoclay nanocomposites are considered as fully exfoliated when inter gallery distance is greater than 10 nm but it was not achieved in many research work. Establishment of exfoliated structures in nanocomposites prepared in industrial scale is the major challenge that NR industry faces at present. NR/nanoclay nanocomposites produced with existing techniques develop high property fluctuations. Therefore, it is necessary to develop a technique to minimize property fluctuations and to obtain a reliable NR based product. It is predicted by this review that co-coagulation technique is the most promising and potential technique to fulfill the requirements of developing a NR/nanoclay nanocomposite. Use of modified nanoclays like Organoclays will aid to obtain a reliable NR based product.

This paper describes a complete path of research, which, starting from analysis and restitution 3D, gets to the virtual exploration of Hypogeum Palmieri in Lecce, a monument of Messapian age (4th century BC) currently not visible by tourists, as it is located in the garden of a private home. This project is developed under the DICET, an Italian National Operative Program, that aims to define and produce innovative models, processes, and tools for the sustainable development of a smart territory by capitalizing on its cultural and environmental resources, and marketing their touristic offerings. The instrumental survey of the Palmieri hypogeum was executed using two different methods, laser scanner and digital photogrammetry, in order to get a high metric control of the monument and high-resolution textures for the sculpted friezes. The two different survey methods allowed a perfect porting on different outputs: the 3D real time visit on the web and virtual visit on portable devices. A stereoscopic animation, installed at the museum MUST (Historic Museum of Lecce) Lecce, provides an easy diffusion of the cultural message. The richness of the textures and the resolution of the models has allowed the study of the monument from a morphological and structural point of view. The virtual reconstruction contributes to read an unpublished part of monumental tombs in Messapian age. Thanks to a cinematic approach with a great scientific rigor, the historical competence of an ordinary visitor is now largely formed on information coming from these media, thus creating a great increase in the demand for products with a high technological content and popularising historical re-evocations and reconstructions of the past.

This paper presents our contribution to the ChaLearn Challenge 2015 on Cultural Event Classification. The challenge in this task is to automatically classify images from 50 different cultural events. Our solution is based on the combination of visual features extracted from convolutional neural networks with temporal information using a hierarchical classifier scheme. We extract visual features from the last three fully connected layers of both CaffeNet (pre-trained with ImageNet) and our fine tuned version for the ChaLearn challenge. We propose a late fusion strategy that trains a separate low-level SVM on each of the extracted neural codes. The class predictions of the low-level SVMs form the input to a higher level SVM, which gives the final event scores. We achieve our best result by adding a temporal refinement step into our classification scheme, which is applied directly to the output of each low-level SVM. Our approach penalizes high classification scores based on visual features when their time stamp does not match well an event-specific temporal distribution learned from the training and validation data. Our system achieved the second best result in the ChaLearn Challenge 2015 on Cultural Event Classification with a mean average precision of 0.767 on the test set.

The accurate estimation of carbon and heat fluxes at global scale is paramount for future policy decisions in the context of global climate change. This paper analyzes the relative relevance of potential remote sensing and meteorological drivers of global carbon and energy fluxes over land. The study is done in an indirect way via upscaling both Gross Primary Production (GPP) and latent energy (LE) using Gaussian Process regression (GPR). In summary, GPR is successfully compared to multivariate linear regression (RMSE gain of +4.17% in GPP and +7.63% in LE) and kernel ridge regression (+2.91% in GPP and +3.07% in LE). The best GP models are then studied in terms of explanatory power based on the analysis of the lengthscales of the anisotropic covariance function, sensitivity maps of the predictive mean, and the robustness to distortions in the input variables. It is concluded that GPP is predominantly mediated by several vegetation indices and land surface temperature (LST), while LE is mostly driven by LST, global radiation and vegetation indices.

Simulation data could be generated by various kinds of software and have different format. The associations among simulation files could also be complicated. However, the existing solutions are usually based on fixed built-in object and not easy to extend. Provenance knowledge of simulation files is also neglected in traditional file systems. To solve the problem, this paper proposes a new simulation data management approach based on ontology tagging and present a flexible and open system. First, a simulation data organization model is established. All the simulation data are put in a simulation project context. The inner objects of project are also illustrated. Second, the file type and provenance ontology of product simulation domain is developed. Through file tagging based on the ontology, files are well organized and the provenance of each file is explicitly maintained. Finally, a neutral method based on web service is designed to enable the communication between our system and heterogeneous PDM systems. The product structure kept in the simulation data management system is used to maintain a product context for simulation data. The developed simulation data management system has been applied in an etching machine development group and practical examples are given to illustrate the effectiveness of the system.

In this paper a new boost fifth-order point of load dc-dc converter is proposed. A digital controller is then designed to ensure load voltage regulation against expected disturbances. The proposed converter is capable of giving a higher voltage gain in comparison to other fourth and fifth-order boost topologies reported in literature. Through steady-state analysis various design expressions for the energy storage elements are obtained. Discrete-time models of the converter are derived, which are then used in digital controller design. A 25 Watt, 12 to 48 V, 100 kHz prototype converter is considered for simulation and experimentation. Simulations and measurements are in close agreement and thus verified the effectiveness of the proposed converter.

Inspired by the success of Lean Manufacturing, various attempts have been made to translate Lean principles into the software engineering domain. As a result, Lean Software Development has gained large attention in the software development community as well as in academia. Unfortunately, it is still difficult to actually implement Lean Thinking as suggested by the pioneers of Lean Software Development, since Lean adopts a more scientific style: a style that invites the practitioner to investigate him or herself where value is created or wasted and to constantly improve in doing so. This extended abstract points out the core ideas presented in the book #x201C;Lean Software Development in Action #x201D;, published by Springer in 2014, which aims to fill this gap.

Visual cultural symbol (VCS) is common around us, and it's very important for cultural study. Especially, it's useful and efficient if we can study VCS through CS. In the Internet, Mostly VCS display as an image. Machine learning is emerging, but image recognition is focused on face or man detective, it's lack of VCS recognition study. Content based image classification techniques are gaining increasing popularity in the visual contents of the images for classifying images to their categories of interest which has been accomplished using various techniques. Feature extraction is an important part of the classification process. In this paper, we mainly using HOG (Histogram of Oriented Gradient), LBP (Local Binary Pattern), RGB, to extract the VCS's contour, texture, color features, respectively, and also comprehend them. The efficiency of feature extraction techniques to implement according to above methodologies are tested using the Support Vector Machines (SVM) Classifier. In all these techniques different degrees of image classification precision and recall has been calculated. There are some impressive conclusions which are made from our experiments.
