In this paper we present a novel technique to capture Web users’ behaviour based on their interest-oriented actions. In our approach we utilise the vector space model Random Indexing to identify the latent factors or hidden relationships among Web users’ navigational behaviour. Random Indexing is an incremental vector space technique that allows for continuous Web usage mining. User requests ar...

We propose distributed protocol for generation of random numbers via computer systems. The protocol is specifically designed to fit the needs of random selection as it is performed in public sphere and is inspired by real problems, which are posing difficulties for Bulgarian judicial system. Random selection in public sphere is meant to be mechanism for increasing the transparency and reducing ...

The prime objective of the this study is to find out Higher Secondary Female Students’ Awareness towards Social Media safety Usage. present investigation has been undertaken by using Normative Survey Method. about Usage Inventory constructed and validated Preet Monk (2017) used for study. was conducted with 200 Students studying in Nagappattinam District Tamilnadu State. sample selected Simple ...

It has recently been demonstrated that human natural codon usage bias is optimized towards a higher buffering capacity to mutations (measured as the tendency of single point mutations in a DNA sequence to yield the same or similar amino acids) compared to random sequences. In this work, we investigate this phenomenon further by analyzing the natural DNA of four different species (human, mouse, ...

Physical Unclonable Functions (PUFs) are widely used to generate random Numbers. In this paper we propose a new architecture in which an Arbiter Based PUF has been employed as a nonlinear function in Nonlinear Feedback Shift Register (NFSR) to generate true random numbers. The rate of producing the output bit streams is 10 million bits per second. The proposed RNG is able to pass all NIST tests...

Random number generators (RNGs) play an important role in many real-world applications. Besides true hardware RNGs, one important class are deterministic random number generators. Such generators do not possess the unpredictability of true RNGs, but still have a widespread usage. For a deterministic RNG to be used in cryptography, it needs to fulfill a number of conditions related to the speed,...

In this paper, we examine two modern enterprise Flash-based solid state devices and how varying usage patterns influence the performance one observes from the device. We observe that in order to achieve peak sequential and random performance of an SSD, a workload needs to meet certain criteria such as high degree of concurrency. We measure the performance effects of intermediate operating syste...

We describe a technique for specifying operational prooles for modules. The technique is more general than those of the current literature and allows more accurate speciication of module usage. We also outline an algorithm for automatically generating random test cases from any such operational proole speciication for a module, such that the test cases correspond to a random sampling of the mod...
