The goal of this project is to have the telepresence robot recognize and follow military hand signals. These signals consist of commands such as Halt, Crawl Forward, Run Forward, Retreat, Flank Left/Right, etc. Upon recognizing a gesture the robot will execute a hardcoded response. The robot will be equipped with a Kinect sensor that detects the skeleton of a human. We have also coded a baselin...

Using monthly forecast data from Consensus Economics Inc. for 18 developed countries reported over 24 different forecast horizons during 1989-2004, we found wide diversity in the quality of forecasts across countries, and the horizons at which forecasts start becoming useful. For only seven countries (viz., Austria, Belgium, Canada, Denmark, Germany, Norway and U.S.) the initial 24-month-ahead ...

A “secure system” should be secure—but should also be a system that achieves some particular functionality. A family of secure systems that our group has been investigating (and building) are high-end secure coprocessors: devices that combine a general-purpose computing environment with high-performance cryptography inside a tamper-responding secure boundary. With the appropriate application so...

INTRODUCTION Stable heterosexual HIV-1 serodiscordant couples in Africa have high HIV-1 transmission rates and are a critical population for evaluation of new HIV-1 prevention strategies. The Partners PrEP Study is a randomized, double-blind, placebo-controlled trial of tenofovir and emtricitabine-tenofovir pre-exposure prophylaxis to decrease HIV-1 acquisition within heterosexual HIV-1 serodis...

The raw material used for this NCC production was oil palm empty bunches (OPEFB), currently waste from plantations. Delignification of OPEFB carried out using 2 N NaOH solution at 70oC 6 hours. maximum yield is 62.1% (dry cellulose basis) obtained a concentration 54% sulfuric acid and temperature 50oC. addition plasticizers (glycerol PEG) reduced the elastic modulus capsules 7951.4 MPa to 4758 ...

We report rate coefficients for the relaxation of OH(v = 1) and OD(v = 1) by H2O and D2O as a function of temperature between 251 and 390 K. All four rate coefficients exhibit a negative dependence on temperature. In Arrhenius form, the rate coefficients for relaxation (in units of 10 12 cm molecule 1 s ) can be expressed as: for OH(v = 1) + H2O between 263 and 390 K: k = (2.4 0.9) exp((460 115...

The automated and formal analysis of cryptographic primitives, security protocols and Application Programming Interfaces (APIs) up to date has been focused on discovering attacks that completely break the security of a system. However, there are attacks that do not immediately break a system but weaken the security sufficiently for the adversary. We term these attacks partial attacks and presen...

This cross-sectional study aimed at estimating prevalence, awareness, treatment, control, and predictors of hypertension among Saudi adult population. Multistage stratified sampling was used to select 4758 adult participants. Three blood pressure measurements using an automatic sphygmomanometer, sociodemographics, and antihypertensive modalities were obtained. The overall prevalence of hyperten...

We carried out optical spectroscopic observations of the galactic supersoft X-ray source RX J0925.7−4758. The relatively long orbital period among supersoft X-ray sources was confirmed. The nature of the secondary star is discussed using its invisibility in the optical spectrum. Under the hypothesis of a non-eclipsing white dwarf, we derived an A–G giant secondary with an inclination angle of 5...
