Aerial eavesdropper Ground BS Legitimate user ... ... Aerial malicious jammer Legitimate links Wiretap links Jamming links ( a ) Eavesdropping

Integrating unmanned aerial vehicles (UAVs) into future wireless systems such as the fifth-generation (5G) cellular network is anticipated to bring significant benefits for both UAV and telecommunication industries. Generally speaking, UAVs can be used as new aerial platforms in the cellular network to provide communication services for terrestrial users, or become new aerial users of the cellular network served by the terrestrial base stations. Due to their high altitude, UAVs usually have dominant line-ofsight (LoS) channels with the ground nodes, which, however, pose new security challenges to future wireless networks with widely deployed UAVs. On one hand, UAV-ground communications are more prone than terrestrial communications to eavesdropping and jamming attacks by malicious nodes on the ground. On the other hand, compared to malicious ground nodes, malicious UAVs can launch more effective eavesdropping and jamming attacks to terrestrial communications. Motivated by the above, in this article, we aim to identify such new issues from a physical-layer security viewpoint and propose novel solutions to tackle them efficiently. Numerical results are provided to validate their effectiveness and promising directions for future research are also discussed.
Segmentation of Masses in Mammographic Images

Image Processing is a process of performing few operations on an image either to obtain an enhanced image or to extract useful information from it. In image processing input provided is an image and output can be image or features associated with particular image. Image processing is one of the most rapidly growing technology in computer science field which also forms the core research area. Image processing techniques are widely used in detection of breast cancers. Segmentation is a process of dividing an image into distinct regions with each pixel having similar properties. Region should strongly relate to the feature of interest to make it more meaningful and useful image analysis. Segmentation is the first step in transforming a greyscale image into one of more other images i.e. from low level image processing to high level image processing. The success of image analysis depends on segmentation but partitioning of an image accurately is a challenging task. This paper presents an approach of automatic breast mass segmentation which has three stages: contour initialization, construction of fuzzy contour and estimation of fuzzy membership maps.
The Next Generation of the Penn World Table †

We describe the theory and practice of real GDP comparisons across countries and over time. Version 8 of the Penn World Table expands on previous versions in three respects. First, in addition to comparisons of living standards using components of real GDP on the expenditure side, we provide a measure of productive capacity, called real GDP on the output side. Second, growth rates are benchmarked to multiple years of cross-country price data so they are less sensitive to new benchmark data. Third, data on capital stocks and productivity are (re)introduced. Applications including the Balassa-Samuelson effect and development accounting are discussed. (JEL C43, C82, E01, E23, I31, O47)
Volatile outgassing and chemical speciation of the C-O-H system in the Earth ́s Magma Ocean

The aim of the research is to improve the present knowledge about the early phase of the Earth ́s evolution, subsequent to the formation of the Moon. In this period the Earth was probably characterized by the presence of a magma ocean or several magma ponds and the silicate melt was the main source of volatiles for the early atmosphere. Specifically, the volcanic degassing and the volatile chemical speciation were investigated through the use of numerical modelling of the outgassed species. We analysed the volatile transition from the mantle to the atmosphere of the C-O-H system by the usage of the equilibrium constants and mass balance method. Considering the oxygen fugacity (ƒO2) as one of the main factors that affects the chemical speciation, we observed changes in the ratio of reduced (H2 and CO) or oxidized (H2O and CO2) species with different ƒO2 values. The results show an interesting aspect of the interaction between the solid/melt phase and the gas phase since the volatile final composition is directly related to the melt oxygen fugacity.
New Attacks on Lifted Unbalanced Oil Vinegar

In 2017, Ward Beullens et al submitted Lifted Unbalanced Oil and Vinegar (LUOV)[1], a signature scheme based on the famous multivariate public key cryptosystem (MPKC) called Unbalanced Oil and Vinegar (UOV), to NIST for the competition for post-quantum public key scheme standardization. The defning feature of LUOV is that, though the public key P works in the extension feld of degree r of F2, the coeffcients of P come from F2. This is done to signifcantly reduce the size of P . This is a totally new design which was not therefore under any scrutiny before the submission. The LUOV scheme is now in the second round of the NIST PQC standardization process. In this paper we introduce a new attack on LUOV. The main idea is to consider some special differentials to develop new approaches to attack the systems.
Development of Quantum Cascade Lasers at 2 . 7 THz for Heterodyne detection

We have developed a single mode emission, low power consumption THz QCL operating at a specified target frequency for sensitive heterodyne detections. The Fabry-Pérot THz QCL is of limited use since its output power is distributed over many spectral modes. The approach we have chosen is the distributed-feedback (DFB) architecture, in particular the 3rd-order DFB grating that can provide single mode emission as well as small beam divergence. To obtain single mode operation at the desired frequency we have fabricated several devices with different grating periods and/or grating duty cycle. This strategy allows to thinly cover a relatively broad range of emission frequencies. Upon electro-optical characterisation of the lasers, the devices that best suit the application can be selected. The laser design is based on judicious electromagnetic modelling. Particular care has been taken to reduce the overall size as much as possible, in order to minimise the power dissipation. We obtained devices with very low electrical dissipation, which is suitable for embedded THz detection systems.

Language independent approach to sentiment anaLysis ( Limsi participation in romip ’ 11 )

Sentiment analysis is a challenging task for computational linguistics. It poses a difficult problem of identifying user opinion in a given text. In this paper, we describe participation of LIMSI in the sentiment analysis track of the Russian annual evaluation campaign (ROMIP’11). The goal of the track was classification of opinions ex pressed in blog posts into two, three, and five classes. Our system based on SVM with dependency graph and ngram features was placed 1st in 5-class task on all three datasets (movies, books, cameras), 3rd in the 2-class task on the movies dataset, and 4th in the 3-class task on the cameras dataset, according to the official results.
Hybrid Watchdog and Pathrater algorithm for improved security in Mobile Ad Hoc Networks

Mobile hosts have a new wireless networking paradigm, called ad hoc networks. These networks do not rely on fixed infrastructures, like traditional wireless networks. To sustain connectivity hosts rely on each other for all communication transactions. The unique properties of ad-hoc networks are promoting an increased trend towards their adoption. The military and other security sensitive operations were the main and first application areas of ad hoc networks, but the trend has shifted now, businesses are relying on them. Mitigating the vulnerability of these networks to security attacks remains the main design challenge for these types of networks. A serious problem common in mobile ad-hoc networks (MANets) is the black hole attacks. The challenge of detecting and eliminating blackhole attacks in mobile ad-hoc networks, has led to poor network performance. This paper focuses on vulnerabilities of MANets and in particular it looks at the blackhole attacks. We present the design of an improved Watchdog and Pathrater algorithm called Radical Watchdog and Pathrater Algorithm for detecting and eliminating Black hole attacks. We carry out an extensive literature review and also make an analysis of the existing techniques for detection and elimination of Blackhole attacks in MANets. Our work culminates with the design of a RWP algorithm for improved security in MANets.
tudy of effect of Stevia rebaudiana bertoni on oxidative stress in type-2 diabetic at models

A clinical condition “Diabetes” is more often associated with the release of a massive amount of toxic free radicals, which significantly decrease the level of antioxidant enzymes, increase lipid peroxidation, and worsen the disease state by causing further hyperglycemia. Many plant extracts and plant-derived natural compounds have been reported to possess antioxidant activities, and useful in preventing the deleterious effects of oxidative stress. Here, we have demonstrated the free-radical scavenging effects of a natural sweetener or a dietary supplement Stevia rebaudiana bertoni standardized extract on diabetes-induced oxidative stress animal model. The present study was also aimed to investigate the effect of this extract on hyperglycemia and hepatic antioxidant enzymes of animal models of type 2, non-insulin dependent diabetes mellitus (NIDDM). The hyperglycemic state was induced by alloxan monohydrate with a dose of 150 mg/kg/b.w. , i.p. Animals of normal treated and diabetic treated groups were administered with a dose educed glutathione uperoxide dismutase tevia extract of 250 mg/kg/b.w. , p.o. , of stevia extract for 28 days and blood sugar levels were measured intermittently. At the end of the experiment, rat liver tissues were collected and the tissue homogenate was assayed for various oxidative scavenging enzymes. The results of hepatic antioxidant enzyme assays and lipid peroxidation clearly indicates that stevia extract have significant antioxidant effect on diabetes pathology. Administration of the extract also reduced the abnormal blood sugar levels significantly (P < 0.001) and improved the hyperglycemic condition. © 2012 Elsevier Masson SAS. All rights reserved.

Conservatism in Equity Valuation ∗

Using a CCAPM-based risk-adjustment model consistent with general asset pricing theory, we perform yearly valuations of a large sample of stocks listed on NYSE, AMEX and NASDAQ over a twenty-year period. The model differs from standard valuation models in the sense that it adjusts forecasted residual income for risk in the numerator rather than through a risk-adjusted cost of equity in the denominator. Further, the riskadjustments are derived based on assumptions about the time-series properties of residual income returns and aggregate consumption rather than historical stock returns. We compare the performance of the model with several implementations of standard valuation models, both in terms of absolute valuation errors, and in terms of the returns on simple investment strategies based on the differences between model and market values in the respective valuation models. The CCAPM-based model performs substantially better than the best of the standard valuation models when comparing absolute valuation errors. Both types of models are able to explain abnormal returns impressively well when constructing investment strategies but also in this setting, the CCAPMbased model outperforms the standard valuation models in most dimensions. We further show that the standard CAPM and the Fama-French three-factor based approaches to riskadjustment substantially overestimate the cost of risk. This “error”more than offsets yet another “error,”which is committed when using analysts’ forecasts of long-term growth, which are three-four times higher than what can be considered reasonable. Using the CCAPM approach to valuation, the results imply that investors are very conservative in their valuation of long-term value creation but also very conservative in risk-adjusting future value creation.

1 INTEGRATED MODELLING 1 D / 2 D AND PERFORMANCE ASSESSMENT TO SUPPORT FLOODS MANAGEMENT . APPLICATION TO STORMWATER URBAN DRAINAGE SYSTEMS IN ESTUARINE AREAS

Urban flooding occurrence has associated significant impacts and negative effects that require an adequate assessment, taking in consideration the different consequences that can be associated with them. This thesis proposes a methodology based on the development and use of a 1D/2D integrated mathematical modelling and, subsequently, the application of the technical performance assessment to support the flood management in estuarine areas. The 1D/2D integrated mathematical modelling is developed using the combination of Mike Urban and Mike Flood software through the application of the Overland Flow tool. The performance assessment in stormwater systems is based on the application of performance indicators (PI) using the information provided by 1D and 1D/2D integrated modelling. The set of PI was based on those from the International Water Association (Matos et al., 2003) for wastewater services, applicable to flooding management of stormwater systems, and some new PI proposed based on the modelling (1D and 1D/2D) capabilities. It is also assessed the advantages and disadvantages of the use of information obtained by 1D/2D modelling in comparison to 1D modelling. The methodology was tested and validated for the case of study of Dafundo where the risk of flooding occurrence is focused on the downtown area. It was possible to identify a significant impact of the operational conditions in the flooding occurrence related to stormwater drainage system, being aggravated for high tide levels on the Tagus estuary.
AN INFORMATION THEORETICAL METHOD FOR ANALYZING UNREPLICATED DESIGNS WITH BINARY RESPONSE

• The analysis of unreplicated factorial designs constitutes a challenging but difficult issue since there are no degrees of freedom so as to estimate the error variance. In the present paper we propose a method for screening active effects in such designs, assuming Bernoulli distributed data rather than linear; something that hasn’t received much attention yet. Specifically, we develop an innovating algorithm based on an information theoretical measure, the well-known symmetrical uncertainty, so that it can measure the relation between the response variable and each factor separately. The powerfulness of the proposed method is revealed via both, a thorough simulation study and a real data set analysis.
Examining users ’ intention to continue using business intelligence systems from the perspectives of end-user computing satisfaction and individual performance

End-user computing satisfaction (EUCS) and individual performance have been recognised by many researchers as critical determinants influencing users’ intention to use information systems. Even though a great deal of attention has been paid to the practical decision-making benefits of BI system adoption, there is still a lack of research to explore the nature of EUCS with BI systems and to investigate factors that affect users’ intention to continue using BI systems after adopting the systems. Therefore, the purpose of this study is to empirically investigate the relationships between EUCS, continuance intention, and individual performance with BI systems. The empirical data collected from 330 users in the Taiwanese electronics industry showed that higher levels of EUCS can lead to increased BI continuance intention and improved individual performance and that higher levels of individual performance will lead to higher levels of BI continuance intention.
Compact Dual-band Parallel Coupled T-shaped SIR Filter for WLAN Applications

In this article, a new compact dual-band bandpass filter was introduced. The filter utilized two operating bands centered at 2.45 GHz and 5 GHz widely used for wireless local area network applications. The filter consists of T-shaped sections of step impedance resonator. The structure is an even symmetrical around electrical or magnetic wall, so the operation mechanism of the filter can be analyzed by an even- and odd-mode transmission line theory. The resonator structure is parallel coupled to a pair of 50 Ω input/output ports. Proper feeding and coupling structures can realize at least two transmission zeros around each of the operating band. To enhance the spurs rejection in the out of the band response of the filter, additive transmission zero at 10 GHz was created by adding stub of quarter guided wavelength at a selected distant from the output port edge. The filter is designed and optimized using the full wave Electromagnetic simulator. The center frequency of the designed bands can be easily refined by the filter dimensions. The overall dimension of the filter is (where is the guided wavelength at the frequency of 2.45 GHz) corresponding to 14.3 mm x 22 mm.
The quest for croatian idioms as multiword units

Idiomatic expressions are types of MWUs in which the meaning of the unit does not equal the meaning of its parts. They are culturally dependent, so the translation cannot be inferred from the expression itself. Croatian language has a very rich idiomatic structure. A few such expressions can be understood in direct translation but most are different from the literal translations. As the idioms are rooted in the tradition of the language and society from which they hail, they need special treatment in computational linguistics. Using NooJ as an NLP tool, we describe different types of Croatian idioms that will help us recognize them in texts. Idioms recognition should be given special treatment, being the major task in translation.
Enhanced Resource Scheduling Approach for Cloud Computing

The various arrangements of resources in terms of assigning hosts to virtual machine, placing tasks on virtual machine and how each virtualized resource is released to the tasks can be handled efficiently via scheduling.
