Malicious Domain Detection Based on Machine Learning

At present, malicious domain detection, especially malicious domain detection based on machine learning, is one of the research hotspot in network security field. In this paper, we first introduce the background knowledge of malicious domain detection and classify the malicious domain according to its malicious behavior. And then we focus on a survey on the detection research of C&C (Command and Control) domain in Fast-flux botnets and Domain-flux botnets which are the most popular and the most challenging. In the end, we also explore some potential future issues in malicious domain detection research.
Hierarchical classification of robotic grippers applied for agricultural object manipulations

An overview of agricultural grippers used to control weeds and harvesting is presented. The classification of the grippers, which are installed on robotic agricultural tools for manipulation of fruits, weeds and other objects, is compiled. There are 22 types of grippers depending on 6 selected criteria: drive type, the presence of the drive in the grip, the number of fingers, the type of gripper movement, the type of mechanism, the type of sensors. In this classification, we mainly consider the characteristics of the gripper, which is installed at the end of the manipulator and is responsible for physical contact with the object. Therefore, the main attention is paid to problems requiring direct capture of objects by the agrobots. The issue of joint interaction of a group of heterogeneous terrestrial and airborne robots in the performance of the target agrarian task in an autonomous mission will also be investigated.

Wrongful Convictions Do Lower Deterrence

The conventional result of the theory of the public enforcement of law is that wrongful convictions of innocents are detrimental to deterrence. This proposition has been challenged recently. In some cases, wrongful convictions do not jeopardize deterrence, because they influence equally the innocent and the guilty. Therefore deterrence does not change. We show that, in general, wrongful convictions do lower deterrence. We prove that wrongful convictions do not jeopardize deterrence only in very limited circumstances or under unlikely assumptions.
Two-Dimensional Particle-In-Cell Simulation of Magnetic Sails

A magnetic sail is spacecraft propulsion that produces an artificial magnetosphere to block solar wind particles and thus impart momentum to accelerate a spacecraft. In the present study, the authors conducted two-dimensional particle-in-cell simulations on small-scale magnetospheres to investigate thrust characteristics of a magnetic sail and its derivative, magnetoplasma sail, in which the magnetosphere is inflated by an additional plasma injection. As a result, the authors found that the electron Larmor motion and the charge separation become significant on such a small-scale magnetosphere and the thrust of the magnetic sail is affected by the cross-sectional size of the charge-separated magnetosphere. The authors also reveal that the plasma injection, on the condition that the kinetic energy of plasma is smaller than the local magnetic field energy (β∼10−3), can significantly inflate the magnetosphere by inducing diamagnetic current in the same direction as the onboard coil current. As a result, the m.
A Method of Detecting Approximate Repetitive News Documents

In view of the phenomenon of too much repeated webpage on the Internet, this paper proposes an approximately duplicate webpage detection algorithm and system , which combined multi-feature fingerprint cluster detection with document similarity detection. In this scheme, the multi-feature fingerprint cluster detection is used first to ensure the precision and efficiency of the algorithm; for small portion of the document that not be recalled, approximately duplicate webpage detection algorithm is used to guarantee the recall rate. The scheme has good improvements in the aspects of precision and recall rate, and at the same time has a good balance on performance.
Evaluation of Close-Range Stereo Matching Algorithms Using Stereoscopic Measurements

The performance of binocular stereo reconstruction is highly dependent on the quality of the stereo matching result. In order to evaluate the performance of different stereo matchers, several quality metrics have been developed based on quantifying error statistics with respect to a set of independent measurements usually referred to as ground truth data. However, such data are frequently not available, particularly in practical applications or planetary data processing. To address this, we propose a ground truth independent evaluation protocol based on manual measurements. A stereo visualization tool has been specifically developed to evaluate the quality of the computed correspondences. We compare the quality of disparity maps calculated from three stereo matching algorithms, developed based on a variation of GOTCHA, which has been used in planetary robotic rover image reconstruction at UCL-MSSL (Otto and Chau, 1989). From our evaluation tests with the images pairs from Mars Exploration Rover (MER) Pancam and the field data collected in PRoViScout 2012, it has been found that all three processing pipelines used in our test (NASA-JPL, JR, UCL-MSSL) trade off matching accuracy and completeness differently. NASA-JPL's stereo pipeline produces the most accurate but less complete disparity map, while JR's pipeline performs best in terms of the reconstruction completeness.
On the Economic Foundation of the Urban Network Paradigm: Spatial Integration, Functional Integration and Economic Complementarities within the Dutch Randstad

Conceptually, the degrees of spatial and functional integration and urban complementarities in economic network relations are hypothesised to be important. In this paper, data on interfirm relations in the Dutch Randstad are used to test conditions for integration and the existence of economic complementarities. A clear hierarchy is observed in the different types of spatial interdependencies in the Randstad, in which the central place model prevails. Furthermore, no evidence is found for the functional integration of municipalities in the Randstad. It is concluded that, at this moment, the Randstad does not function as a spatially and functionally integrated region and that spatial economic policy can better focus on smaller regions within the Randstad. This also calls into question the applicability of the urban network concept in general, as the Dutch Randstad is usually seen as a prime example of an economically successful polycentric urban system.
Indiscipline, or, The Condition of Comics Studies

“The structure of the research university needs serious rethinking,” says James Chandler, in his contribution to Critical Inquiry’s 2003 symposium on “The Future of Criticism. ” Calling for, a la Foucault, a historical epistemology of the academic disciplines and indeed the very concept of disciplinarity, Chandler hopes for both “a more rigorous account of what a discipline is” and the exploration of “new possibilities for interdisciplinary connection and exploration” (359). This essay will, i.
The Role of Temperament and Anxiety on Somatization in Young Adults

THE ROLE OF TEMPERAMENT AND ANXIETY ON SOMATIZATION IN YOUNG ADULTS Deepti Gupta, M.A. George Mason University, 2009 Thesis Director: Dr. Koraly Perez-Edgar The current study examined the role of temperament and anxiety on somatizing behavior in young adults (N=230). Participants completed a series of self-report measures assessing levels of behavioral inhibition, social anxiety, thought suppression, as well as a multidimensional somatization symptom profile. Gender and ethnicity were also noted as they may act to moderate the temperament-anxiety-somatization link. Analyses were carried out using a linear regression model. Results found that temperamental characteristics like neuroticism, social avoidance, and thought distortion together constituted a single factor – socio-affective vigilance. Regression analysis showed that socio-affective vigilance and low threshold were significant positive predictors of somatic behavior and anxiety in young adults. Data analysis showed that in the present sample, this relation held only for Caucasians. No ethnic differences were found on anxiety scores. While women reported significantly more somatic complaints, gender did not moderate the relation between socio-affective vigilance, low threshold, and somatization.
An empirical investigation of chairperson's report - A comparison between secretive and transparent value oriented countries

Following Hofstede’s (1980, 1991, 2001) and Gray’s (1988) propositions on the effects of cultural variables on accounting disclosure practices it is expected that annual reports of a transparent value oriented country would provide more voluntary disclosure compared to a secretive value oriented country. This study investigated the proposition that India having more secretive culture compared to New Zealand, the chairpersons’ statements in the annual reports of the Indian companies would disclose less information compared to the chairpersons’ statements in the annual reports of the New Zealand companies. However, the evidence as provided in the study on the contrary suggests that Indian companies in fact, provided more voluntary information in their Chairpersons’ statement compared to their New Zealand counterparts. The study argues that voluntary disclosure (chairpersons’ report itself is voluntary) is a complex phenomenon and cultural variables alone are not capable of predicting voluntary disclosure practices of a country as these practices are also influenced by other organisational antecedents, such as environmental conditions, industry norms and market competition.
Expressing Efficiency as a Function of Key Performance Control Parameters: A Case Study of Hydrocyclone Unit Process at Josay Goldfields Limited, Tarkwa, Ghana

Optimization of gold liberation is a function of hydrocyclone (cyclone) classi-fication efficiency with regard to a given target of 80% passing 75 μm at Josay Goldfields Limited. Key performance parameters that control the classification efficiency are hydrocyclone feed density, hydrocyclone feed pressure and throughput under fairly constant grinding process conditions. The hydrocyclone feed density related linearly to overflow product of percentage passing 75 μm and showed statistical linearity at even 1% critical level of significance. The paper provides a relation between cyclone feed density and cyclone overflow product size fraction as a function of cyclone efficiency. Gradient of the relation establishes the standard unit of performance which depicts the classification efficiency as percentage passing 75 μm per percentage solids of cyclone feed density. This measurement provides a timely corrective action of key performance control parameters. The selected seven days samples space used in the assessment was due to the effect of a daily production deficiency on the overall profit margin of Josay Goldfields as company.
A Fast Retrieval Algorithm Based on Fibonacci Hashing for Audio Fingerprinting Systems

In audio fingerprinting system, the database consists of hundreds of millions of sub-fingerprints. How to find out the most similar audio in the shortest time and use less memory in huge repository of sub-fingerprints is a hot topic of research. Recently, Philips introduced an effective search method based on hash table. In this paper, a fast retrieval algorithm based on the Fibonacci Hashing is proposed as an extension of Philips's method. The algorithm uses Fibonacci Hashing function which can adjust the size of hash table according to capacity of memory, provide a good distribution of hash value, and save memory. The performance of presented algorithm has been evaluated by experiments. Index Terms - audio retrieval, Fibonacci Hashing, audio fingerprint, hash table.
Mineral phosphate solubilization by Pseudomonas aeruginosa isolates from chilli ( Capsicum annuum L.) fields

Phosphorus (P) is the second imperative key element after nitrogen as a mineral nutrient in terms of quantitative plant requirement. An adequate supply of P is obligatory for proper execution of various metabolic activities of plants. Identification of a potent phosphate solubilizing microorganism capable of transforming insoluble P into soluble and plant accessible forms is considered as the best eco-friendly option for providing inexpensive P to plants. In this study 12 phosphate solubilizing microorganisms were isolated from chilli rhizosphere by enrichment culture technique. P solubilisation efficiency was checked using vanadomolybdate phosphoric yellow colour method and two most efficient isolates, PS 2 and PS 3, were selected. Various parameters such as pH, temperature of incubation, carbon source, nitrogen source, NaCl concentration and incubation time were optimized for the selected isolates, Pseudomonas aeruginosa PS 2 (KR270346) and Pseudomonas aeruginosa PS 3 (KR270347). Maximum P solubilization rate was shown at pH 7, temperature 30°C and after 15 days of incubation. Glucose and ammonium sulphate were the best carbon and nitrogen sources for the selected isolates. Mineral phosphate solubilization was directly related to a pH drop in the culture medium. Production of gluconic acid by Pseudomonas aeruginosa during phosphate solubilization was confirmed by analyzing the culture medium by high performance liquid chromatography. The growth stimulation effect of selected isolates was confirmed by the vigour index determination and the treated rice seeds showed better germination percentage than control seeds.

Buoyancy-driven inflow to a relic cold core: the gas belt in radio galaxy 3C 386

WereportmeasurementsfromanXMM–Newtonobservationofthelow-excitationradiogalaxy 3C 386. The study focusses on an X-ray-emitting gas belt, which lies between and orthogonal to the radio lobes of 3C386 and has a mean temperature of 0.94 ± 0.05 keV, cooler than the extended group atmosphere. The gas in the belt shows temperature structure with material closer to the surrounding medium being hotter than gas closer to the host galaxy. We suggest that this gas belt involves a ‘buoyancy-driven inflow’ of part of the group-gas atmosphere where the buoyant rise of the radio lobes through the ambient medium has directed an inflow towards the relic cold core of the group. Inverse-Compton emission from the radio lobes is detected at a level consistent with a slight suppression of the magnetic field below the equipartition value.
Keeping the Bubble Alive! The Effects of Urban Renewal and Demolition Subsidies in the East German Housing Market

German urban renewal programs are favoring the cities in the Eastern part since the reunification in 1990. This was accompanied additionally by attractive tax incentives, designed as an accelerated declining balance method of depreciation for housing investments during the late 1990s. The accumulated needs for comfortable housing after 40 years of a disastrous housing policy of the GDR era were generally accepted as justification for the subvention policy. But various subsidies and tax incentives caused a construction boom, false allocations, and a price bubble in Eastern Germany. After recognizing that the expansion of housing supply was not in line with the demographic development and that high vacancy rates were jeopardizing housing companies and their financial backers, policy changed in 2001. Up to now, the government provides demolition grants to reduce the vast oversupply. By means of a real option approach, it is explained how different available forms of subsidies and economic incentives for landlords lift real estate values. The option value representing growth expectations and opportunities is calculated as an observable market value less an estimated fundamental value. Empirical results disclose higher option premiums for cities in Eastern Germany and a strong correlation of the option premium with urban renewal spending.
Direct numerical simulations of spots

Although many properties of turbulent spots have been determined by laboratory measurements and flow visualization, there still remain unanswered questions about the mechanisms involved in the spreading of spots, the role of instability waves, and the structure of the turbulent flow within and the non-turbulent but modified flow outside spots, Direct numerical simulations offer detailed, well-resolved data which could reveal these mechanisms. A few such simulations have been done in flat plate boundary layers, in channel flows (Poisueille and Couette flows) and in pipe flows. Although one study has examined the growth and breakdown of instability waves at the edges and another has computed particle trajectories to determine where fluid is entrained, most of these studies have only reached the stage of establishing the correctness of the simulations by comparisons with features observed in laboratory flows. However, it is a reasonable expectation that in the near future, simulation studies will begin to make definitive statements about mechanisms of spot growth and propagation.
Corrigendum to “Haptic Decorating on the Surface of Virtual Clay Model”

A novel haptic decorating method on the surface of virtual clay model is proposed. The relationship between brush deformation and endured force is researched for the first time by applying the spring-mass model to construct the 3D brush model. Then, the collision detection between virtual hairy brush and virtual claymodel is researched based on collision algorithmofweighted average distance. When the hairy brush initially collides with 3D exterior, the tactility is simulated and the interactive virtual painting on the 3D exterior is carried out practically. The 3D brush stroke is formed by superimposing 3D brush footprints along the painting direction and controlling the stress of the brush. The ink quantity in the brush footprint is determined according to the proposed positive correlation between the exerted pressure on brush and outflow ink quantity of the brush. A painting storage method is also presented for storing and displaying 3D stroke painting results. The proposed method has been successfully applied in the 3D virtual painting system based on real-time force feedback technology. With this system, the 3D brush strokes with 3D half-dry and ink diffusion results can be painted with a Phantom Desktop haptic device, which effectively enhance reality to users.
Evaluation of PGAA data for provenance of lithic artifacts

Abstract. The objectives of the study were to determine whether Prompt Gamma Activation Analyses (PGAA) could be successfully used to trace the source(s) of various Neolithic artifacts made of microcrystaline quartz. Two macroscopically identical sources of jasper from central and western Romania were analyzed by PGAA along with five Neolithic artifacts from the Limba site (Alba County). Due to the limited number of trace elements, which can be measured by PGAA, this method when used alone might produce inconclusive results for discriminating between jaspers from different sources. The interpretation of the data may be used for general assessments of provenance involving larger sample sets or in combination with optical microscopy. Key words: PGAA, geochemistry, microcrystalline quartz, lithic artifacts, provenance, Romania, Neolithic. OVERVIEW Studies of provenance are valuable to archaeologists and historians because they lead to a better understanding of the existence and development of trade routes and procurement patterns in the past. The most commonly found material, which could be used to determine Stone Age trade routes, is microcrystalline quartz (MCQ). A large problem in sourcing MCQ artifacts such as chert (flint), jasper, and chalcedony, is that macroscopically they may look very similar, even if they come from different sources. From a mineralogical and chemical point of view, they are almost pure SiO
Duration Modelling of Calgary Household Weekday and Weekend Activities: How Different Are They?

A desirable activity-based travel demand modeling framework should be able to address both weekday and weekend activities. However, a literature review shows previous research efforts have mostly focused on investigating weekday activities. Little or no research exists to quantify the differences between weekend and weekday activities. The best knowledge to date is limited to weekday and weekend activities starting at different time of the day and with different participation rates. This study aims to fill the gap by studying the differences between weekday and weekend activities in Calgary, Canada, in terms of their participation rates, starting time, duration and inferred location choices. This study clearly shows the weekend activities are different from their weekday counterparts and suggests that they should be treated separately in activity-based modeling frameworks.
Late glacial palaeoceanography of Hinlopen Strait, northern Svalbard

Timing and structure of the Late and post-glacial development of the northern Svalbard margin, together with the initial influx of Atlantic water into the Arctic Ocean are still very poorly constrained. We investigated a sediment core (NP94-51) from a high accumulation area on the continental shelf north of Hinlopen Strait with the purpose of resolving the timing and structure of the last deglaciation. Detailed analyses of ice-rafted detritus, benthic and planktonic foraminiferal fauna, diatom flora, grain size and radiocarbon dates are used to reconstruct the palaeoceanographic evolution of the area. Our results indicate that the disintegration of Hinlopen Strait ice and possibly the northern margin of the Svalbard Ice Sheet commenced between 13.7 and 13.9 14C Ky BP. Influx of subsurface Atlantic waters into the area (12.6 14C Ky BP) and the retreat of the sea ice cover, with the accompanying opening of the surface waters (10.8 14C Ky BP), happened at different times and both much later than the disintegration of the ice sheets. The transition into the Holocene shows a two-step warming.
