A large amount of unstructured documents exists on the web incorporating data of paramount importance for the enterprises that can employ them to synthesize the past, to comprehend the present and to predict the future. However, it is worth noting that the unstructured nature of these documents made the handling and the extraction of knowledge from them a very critical issue. The current contribution is three-fold. First, we collect the unstructured documents which might be useful using general enterprise ontology. Then, we select the most suitable ones using specific ontologies that describe partial enterprise activities. Finally, we transform the kept documents into parsabale and requestable XML files that can be the corpus for future data extraction.

Positron emission tomography (PET), is a medical imaging technique, it provides information about the body’s cellular function rather than its anatomy. However, due to the functional nature of PET images, locating the anatomical structures in such an image remains a challenging task, indeed, PET images only provide very little anatomical information. Segmentation of PET images, therefore, requires the intervention of a medical expert. The expert proceeds to a manual segmentation of a volume slice by slice, which turns out to be very tedious and costly in terms of time. In this article, we present, evaluate, and make available a multi-atlas approach for automatically segmenting human brain PET image combining both the information provided by the PET volume to be segmented and prior knowledge of the volume provided in the form of multi-anatomical atlas. This also performs comparably to single atlas extraction, multi-atlas methods to improve the accuracy of the defined region. As shown in this study, we achieved significant improvement after the integration of this approach with two widely used multi atlas based segmentation (MAS) methods on BIC database provided by McConnel Brain Imaging Center Montréal and LONI database (USC Neurological Imaging Laboratory).
正电子发射断层扫描(PET)是一种医学成像技术，它提供有关人体细胞功能的信息，而不是其解剖结构。然而，由于PET图像的功能特性，在这样的图像中定位解剖结构仍然是一项具有挑战性的任务，实际上，PET图像只能提供很少的解剖信息。因此，PET图像的分割需要医学专家的介入。专家开始对一个体积切片进行人工分割，这是非常繁琐和昂贵的时间方面。在这篇文章中，我们提出、评估并提供了一种多图谱方法来自动分割人脑PET图像，该方法结合了待分割PET体积提供的信息和以多解剖图谱形式提供的体积的先验知识。与单图谱提取、多图谱提取方法相比，该方法也提高了定义区域的准确性。在本研究中，我们将该方法与两种广泛使用的基于多图谱的分割(multi atlas based segmentation, MAS)方法在McConnel Brain Imaging Center montr提供的BIC数据库和LONI数据库(USC Neurological Imaging Laboratory)上进行整合，取得了显著的改进。

In this work, the nonlinear dynamics of the fractional-order cancer tumor growth model are investigated. The stability of the equilibrium points of the proposed fractional system is analyzed by varying both the fractional-order derivatives and one of the system parameters. Moreover, the dynamical behaviors of the models are compared with each other. Numerical simulations are performed to illustrate the analytical results by considering the Caputo fractional derivative and results are reported by means of bifurcation diagrams, computation of the largest Lyapunov exponent, and the phase portraits. The model can explain many biologically observed tumor states and dynamics, such as stable, periodic, and chaotic behaviors in the steady states. Under some conditions, the interactions between tumor cells, healthy host cells, and effector immune cells show that the tumor could become invasive.

We analyze the (s, S) replenishment policy for a queueing inventory system with a finite sources, service time and customers search from the orbit. Assuming the search time to be negligible, detailed Generalized Stochastic Petri Net (GSPN) model which copes with the complexity of this inventory system is given. The probability distribution of this system is obtained. Using this probability distribution, we compute some measures and the expected cost rate.

In this work, we analyzed via the Generalized Stochastic Petri Nets (GSPNs) approach, a continuous review inventory system according to the (s,Q) replenishment policy, with batch arrivals of demands with deterministic size n, following a Poisson process, which are served immediately, if the stock is available. In the case of out of stock situation, the demands are directed into a limited orbit, if this latter is not complete and repeat their requests after an exponentially distributed time. If the orbit is complete, these demands are definitively lost. Thus, we describe the dynamics of the system considered by a bidimensional continuous time Markov chain, which represents the inventory level and the number of demands in the orbit. Then, we find the stationary distribution, using a recursive algorithm, from which we derive various performance measures of the model.

At present, the Information security against attacks is considered as a key point in the success of most institutions, thus the security of persons' identity is therefore primary to these successes. For that, biometrics techniques were adopted for reinforcing the security of information systems by considering their effectiveness compared to traditional techniques. On this basis, this paper proposed an effective multimodal biometric system utilizing two hand biometrics (palmprint and palm-vein). In this work, two LBP based texture analysis variants which are Three-Patch based LBPs (TP-LBP) and Four-Patch based LBPs (FP-LBP) are used. The presented work of the security analysis can aid in grasping what a biometric system is, therefore getting an effective solution to safeguard information systems. The experimental results determined that the proposed system utilizing a multibiometric dataset of 300 persons showed a high identification rate in addition to a considerable low classification error compared to the existing techniques.

The emergence of electronic copies of the Holy Quran has allowed an increase in the phenomenon of reading and sharing Arabic verses among internet users. The Quran has been brought together in one book to maintain the order and integrity of its content. Changing the order of verses is considered as a degradation of the Holy Quran, resulting in new surahs in the form of a new composition, contradicting the structure and meaning of what is in the Ottoman Quran. Similar to any verification methodology, this study aims to apply deep learning algorithms to automatically authenticate the integrity of the Quranic content arrangement. The Long Short-Term Memory (LSTM) algorithm was chosen in this work, and the results achieved a test accuracy of 99.98% on the dataset that we created using Tanzil website data.

The present study propose a smart tooled process based on an MDA approach for the design of ubiquitous applications taking into account context information in order to deliver high-added value services. We will present our platform-independent model (PIM) associated with a graphical modeling workshop (editor) which will allow us to instantiate in a graphical way in order to obtain PIM models, which will be transformed into PSM. We illustrate its implementation on a prototype application in a pervasive environment that tracks the movements of persons who have tested positive to anticipate COVID-19 contaminations.

In this paper, we prove that a class of differential system of degree nine is Liouville integrable by transforming it into a Bernoulli differential equation and we determine exactly its first integral. This allows us to show that this class admits an explicit non-algebraic limit cycle enclosing the origin, here a non-elementary singular point. For singularities, at infinity, this class does not possess singular points.
