In the face of widespread DEP and ASLR deployment, JIT spraying brings together the best of code injection and code reuse attacks to defeat both defenses. However, to date, JIT spraying has been an x86-only attack thanks to its reliance on variable-length, unaligned instructions. In this paper, we finally extend JIT spraying to a RISC architecture by introducing a novel technique called gadget ...

As a vector control program to control Chagas disease in Guatemala, residual spraying of Rhodnius prolixus and Triatoma dimidiata was performed, and its impact was measured in the department of Zacapa. In order to identify infested villages and determine the degree of infestation, a baseline entomological survey to identify municipalities infested with vectors followed by an additional vector s...

Phase Perturbation Method (PPM) is introduced as a new phase-only synthesis method to design reflectarray antennas so as their sidelobe level is reduced. In this method, only the reflected phase of conventional unit cells are perturbed from their required values. To this end, two approaches namely the conventional Optimization method and newly introduced Phase to Amplitude Approximation (PAA) m...

The continuous spraying was adopted by most of spraying pesticide systems, which can not accord to the extent and the characteristic change of targets to automatically regulate dose of drugs. This way not only resulted in waste of pesticides, but also caused pollution of environment. The designing studied the variable spraying pesticide system of real-time, which based sensory technology, at th...

Ergonomic intervention in spraying operation can provide a reasonable basis for recommendation on operating methods and improvement in operation for more output and safety. Two commercially available sprayers namely knapsack sprayer and rocker sprayer were evaluated with nine male subjects for the study. Age, weight and height of the selected subjects are 30.33±1.93 years, 68.33±9.51 kg and 168...

Data on inhalational and potential dermal exposures during spray application of liquid biocidal products were generated. On the one hand, model experiments with different spraying devices using fluorescent tracers were carried out to investigate the influence of parameters relevant to the exposure (e.g. spraying equipment, nozzle size, direction of application). On the other hand, measurements ...

To reduce a film-diffusional resistance in the very vicinity of the photocatalyst surface, titanium oxide particles containing a small amount of adsorbent particles (310 %) are immobilized on a stainless steel screen by a spraying method and its performance is investigated by decomposing 2,4-dinitrophenol in water. It is found that the activity of this photocatalyst screen is higher than that o...
