Motivated by the representation of biometric and multimedia objects, we consider the problem of hiding noisy point-sets using a secure sketch. A point-set X consists of s points from a d-dimensional discrete domain [0, N−1]. Under permissible noises, for every point 〈x1, .., xd〉 ∈ X, each xi may be perturbed by a value of at most δ. In addition, at most t points in X may be replaced by other po...

Feeding fibre and branched-chain amino acids (BCAA) to sows during late gestation lactation, respectively, have been shown improve litter weights at weaning. Therefore, supplementing primiparous sow diets with lucerne chaff, a feedstuff high in fibre, BCAA tryptophan, may the performance of their progeny. Experiment 1 investigated effects feeding (n = 118) either (i) control diet (CON); (ii) CO...

background: current who best infection control practices for injections do not address the use of hub cutters due to insufficient evidence on safety and efficacy. objective: to assess the impact of the use of hub cutters on 1) the frequency of needle-stick injuries (nsis) and other blood exposures among workers and 2) the volume of sharps waste in a mass vaccination campaign setting. methods: d...

Multi-component cutting force sensing systems in manufacturing processes applied to cutting tools are gradually becoming the most significant monitoring indicator. Their signals have been extensively applied to evaluate the machinability of workpiece materials, predict cutter breakage, estimate cutting tool wear, control machine tool chatter, determine stable machining parameters, and improve s...

5-Axis machining has been widely used in manufacturing of complex ruled geometries in automobile, aerospace, energy, and mould industries. Compared with traditional 3-axis machining, this machining operation offers better shaping capability and productivity with additional degrees of freedom in the tool motion. Tool path planning is a challenging task in most 5-axis machining operations, with t...

A virtual reality machine shop environment was developed for the determination of critical quantitative and qualitative machining process parameters. Material removal and milling machine axes kinematics are simulated in real time. The G-Code program serves as the input to the system. A graphical model for the calculation of quantitative data affecting the machined surface roughness was develope...

The present technology commonly uses manually operated devices to cut the grass, creating pollution and energy loss. In this project, we introduce automatic grass cutter for cutting grass. Automatic can able decrease workload of grasses in field; also this, operating force is given by rechargeable battery that fixed cutter, sensors, crane mechanism find out unwanted things get around while oper...

The paper presents the cutting by generating of spur gears using a rack cutter with modified geometry. In order to find geometry new gears, proper programme has been developed. this gear is compared one same parameters but obtained standard cutter. differences between two are insignificant tool simpler and higher durability.
