Freedom in the wilderness: A study of a Darknet space

Mass media and journalistic accounts of Darknets have focused disproportionately on their criminogenic aspects. Moreover, research has focused mainly on the Darknet technology Tor. We wish to expand scholars’ knowledge of Darknets by exploring a different Darknet technology, Freenet. Using a combination of content analysis and grounded theory, this research asked three progressively complex questions. First, we asked: What are the types of content and the distribution of content on Freenet? Our findings show that Freenet fosters a singular distribution of content, with a high ratio of blogs (or flogs), child pornography, empty links, and Web 1.0 websites that archive information. We assumed that this content is not discrete points of data but instead produce sociologically interesting phenomena. Therefore, we ask: What are the content patterns on Freenet? Four patterns were identified. Freenet is (1) an archive of deviant data resistant to censorship, (2) a space dominated by content associated with masculinity, (3) a nonmarket space where commercial exchange is nonexistent, and (4) an empty space with many requests not returning information, and many flogs abandoned. We asked a third question: How does the analysis of Freenet inform current understandings of hacker culture? Freenet, we suggest, can be understood as a type of digital ‘wilderness’. It is a singular Darknet space, supporting a distinct set of hacker practices.

Material distributions

The concept of material distribution is introduced as describing the geometric material structure of a general non-uniform body. Any smooth constitutive law is shown to give rise to a unique smooth integrable singular distribution. Ultimately, the material distribution and its associated singular foliation result in a rigorous and unique subdivision of the material body into strictly smoothly uniform components. Thus, the constitutive law induces a unique partition of the body into smoothly uniform sub-bodies, laminates, filaments and isolated points.

New record of blue swimming crab Callinectes sapidus Rathbun, 1896 (Crustacea: Portunidae) for the state of Rio Grande do Norte, Northeastern Brazil

The species Callinectes sapidus is reported for the first time in the state of Rio Grande do Norte, Northeastern Brazil. In Brazil, this species is only known from the state of Rio Grande do Sul to the state of Paraíba. In this work, one more gap about the distribution of this species was discovered. Samplings were gathered in two localities: Cavalos River and Ceará-mirim River, north and east coast of Rio Grande do Norte, respectively. This new record increases information about the singular distribution of this species, known for being the only species of Callinectes with disjoint distribution in the Americas.

The Influence of the Capacity-Increasing in the Trailing-Edge Cutting of HL240 Turbine Blade

In the precondition of calculating the flow field around the blade with the singular distribution way, the hydraulic characteristic after cutting the mixed-flow blade is calculated by CFD software , the optimum value of output in HL240-WJ50 water turbine and the influence of the flow field are found out by using that way: when the cutting measure of the cutting tip is 9.4mm, the output of the rotating wheel is increased 5.7% and the characteristic of cavitations isn’t clearly worsened. The improved water turbine blade is applied to the capacity-increasing rebuild of the small electric station. The cutting measure is 5 percent of the average of the blade’s upper canopy and lower rim. The power of the rotating wheel is improved from 232KW to 253KW after cutting, and the output can reach the requirement of the electric station. So the lesser economy to the trailing-edge can get into the better goal of rebuilding, that is suitable to rebuild the small hydraulic power station’s wheel.

On the Convolution Equation Related to the Diamond Klein-Gordon Operator

We study the distributioneαx(♢+m2)kδform≥0, where(♢+m2)kis the diamond Klein-Gordon operator iteratedktimes,δis the Dirac delta distribution,x=(x1,x2,…,xn)is a variable inℝn, andα=(α1,α2,…,αn)is a constant. In particular, we study the application ofeαx(♢+m2)kδfor solving the solution of some convolution equation. We find that the types of solution of such convolution equation, such as the ordinary function and the singular distribution, depend on the relationship betweenkandM.
