Graphical Password: Usable Graphical Password Prototype

Recently, graphical passwords have become a viable alternative to the conventional passwords due to their security and USAbility features. However, there are very limited researches in classifying, analyzing and development of the graphical password techniques. In this paper, we will propose a new USAble graphical password prototype of the recognition base graphical password. In this design we will focus on the USAbility features of the system to give new USAble graphical password system. Graphical passwords schemes are an alternative authentication method of the conventional password scheme in which users click on images to authenticate themselves rather than type the conventional passwords as letters or numbers or mixed. This research aims to design and come out with a new USAble graphical password prototype with the major important USAbility features. In this paper we will focus on implementation of the USAbility features on the new graphical password prototype design. This USAbility set includes the easy of use, memorize, creation, learning and satisfaction. Moreover, this work proposes to build a new system of graphical password system that provides promising USAbility features

Turn-by-wire: Computationally mediated physical fabrication

Advances in digital fabrication have simultaneously created new capabilities while reinforcing outdated workflows that constrain how, and by whom, these fabrication tools are used. In this paper, we investigate how a new class of hybrid-controlled machines can collaborate with novice and expert users alike to yield a more lucid making experience. We demonstrate these ideas through our system, Turn-by-Wire. By combining the capabilities of a traditional lathe with haptic input controllers that modulate both position and force, we detail a series of novel interaction metaphors that invite a more fluid making process spanning digital, model-centric, computer control, and embodied, adaptive, human control. We evaluate our system through a user study and discuss how these concepts generalize to other fabrication tools

Almost graphical hypersurfaces become graphical under mean curvature flow

Consider a mean curvature flow of hypersurfaces in Euclidean space, that is initially graphical inside a cylinder. There exists a period of time during which the flow is graphical inside the cylinder of half the radius. Here we prove a lower bound on this period depending on the Lipschitz-constant of the initial graphical representation. This is used to deal with a mean curvature flow that lies inside a slab and is initially graphical inside a cylinder except for a small set. We show that such a flow will become graphical inside the cylinder of half the radius. The proofs are mainly based on White's regularity theorem.Comment: 33 page

Aplikasi theorema aliran pada subdigraph untuk menentukan barisan graphical

Barisan Graphical merupakan salah satu aplikasi dan i theorema aliran untuk permasalahan subdigraph. Barisan graphical ini merupakan barisan dari derajat titik sehuah graph. Sebuah graph (p,O) cliperoleh dari sebuah digraph (p,O) dengan suatu transformasi dasar (p,O) d-invarian. Sebuah digraph (p,O) yang ditransfonnasi harus memenuhi kondisi sirkuit ganjil. dan jumlah derajat keluar genap yang sama dengan jumlah derajat masuk dari setiap titiknya. Hasii transformasi ini merupakan sehuah digraph (p,O) simetri yang disebut juga graph(p,0). Suatu barisan dari n integer nonnegatif disebut sebagai barisan graphical jika jumlah dari barisan tersebut adalah genap dan dapat direalisasikan ke dalam sehuah graph. Barisan graphical dapat diubah menjadi barisan dual untuk mempercepat proses penyelesaian graphical (p,O) yang diinginkan dan selanjutnya dapat diubah menjadi barisan modifikasi dual untuk penyelesaian graphical (1,0) yang diinginkan. Graphical sequence is one of applications flows theorem for subdigraph problems. Graphical sequence is the sequence of node degree of graph. Given graph (p,O) is determined from digraph (p,O) with elementary (p,O) d-invariant transformation. Digraph (p,O) which is transformed must be satisfy odd-circuit condition and the addition of outgoing degree is even number that equal incoming degree in every node. The result is digraph (p,O) symetry called graph (p,0). A sequence of n nonnegative integer is graphical sequence if the addition of sequences is even number and. can be realized into a graph. Graphical sequence can be changed into dual sequence to process the graphical (p,0) solution and form modification dual sequence .to determine a graphical (1,0)

On Graphical Models via Univariate Exponential Family Distributions

Undirected graphical models, or Markov networks, are a popular class of statistical models, used in a wide variety of applications. Popular instances of this class include Gaussian graphical models and Ising models. In many settings, however, it might not be clear which subclass of graphical models to use, particularly for non-Gaussian and non-categorical data. In this paper, we consider a general sub-class of graphical models where the node-wise conditional distributions arise from exponential families. This allows us to derive multivariate graphical model distributions from univariate exponential family distributions, such as the Poisson, negative binomial, and exponential distributions. Our key contributions include a class of M-estimators to fit these graphical model distributions; and rigorous statistical analysis showing that these M-estimators recover the true graphical model structure exactly, with high probability. We provide examples of genomic and proteomic networks learned via instances of our class of graphical models derived from Poisson and exponential distributions.Comment: Journal of Machine Learning Researc

Synthesising Graphical Theories

In recent years, diagrammatic languages have been shown to be a powerful and expressive tool for reasoning about physical, logical, and semantic processes represented as morphisms in a monoidal category. In particular, categorical quantum mechanics, or "Quantum Picturalism", aims to turn concrete features of quantum theory into abstract structural properties, expressed in the form of diagrammatic identities. One way we search for these properties is to start with a concrete model (e.g. a set of linear maps or finite relations) and start composing generators into diagrams and looking for graphical identities. Naively, we could automate this procedure by enumerating all diagrams up to a given size and check for equalities, but this is intractable in practice because it produces far too many equations. Luckily, many of these identities are not primitive, but rather derivable from simpler ones. In 2010, Johansson, Dixon, and Bundy developed a technique called conjecture synthesis for automatically generating conjectured term equations to feed into an inductive theorem prover. In this extended abstract, we adapt this technique to diagrammatic theories, expressed as graph rewrite systems, and demonstrate its application by synthesising a graphical theory for studying entangled quantum states.Comment: 10 pages, 22 figures.
