Heap spraying is a security attack that increases the exploitability of memory corruption errors in type-unsafe applications. In a heap-spraying attack, an attacker coerces an application to allocate many objects containing malicious code in the heap, increasing the success rate of an exploit that jumps to a location within the heap. Because heap layout randomization necessitates new forms of a...

variable rate spray applications using proportional control systems can greatly reduce pesticide use and off-target contamination of environment in orchards. variable rate spraying of the canopy allows growers to apply pesticides only to the target, only use the correct quantity according to canopy size, season and growth stage and to apply plant protection products in an economic and environme...

to investigate the efficiency of eradicane application, using herbigation as compared with conventional method (spraying), concerning weed biomass and density reduction and change in corn grain yield, a factorial experiment was conducted based on randomized complete block design in 2006 at research fields of university of tehran (karaj). eradicane was applied at 4.5 (labeled rate), 3.15 or 5.85...

BACKGROUND & OBJECTIVES Impact of indoor residual spraying of DDT on malaria transmission and vector density was evaluated in six villages of Shergarh PHC, Bareilly district, Uttar Pradesh under the operational condition of National Vector Borne Disease Control Programme (NVBDCP) from July 2001 to March 2002 (one transmission season only). METHODS Two rounds of DDT (50% WDP) spraying @ 1 g/m2...

A vacuum microplasma spray system, operating on gross power levels of 1-3 kW, with powder feed rates below 1 g/min and using plasma gas mixtures of argon and hydrogen, was built and tested. In order to improve the deposition efficiency and quality of coatings, the system was analyzed and the matter of particle entrainment into the plasma jet core was identified as a critical sub-process. Partic...

In this paper, we study cost efficient multi-copy spraying algorithm for routing in Delay Tolerant Networks (DTN) in which source-to-destination path does not exist most of the time. We present a novel idea and the corresponding algorithm for achieving the average minimum cost of packet transmission while maintaining the desired delivery rate by the given deadline. The number of message copies ...

We examined whether the spraying of soybean leaves with hydrogen peroxide (H2O2) would alleviate the symptoms of drought stress. Pre-treatment by spraying leaves with H2O2 delayed foliar wilting caused by drought stress compared to leaves sprayed with distilled water (DW). Additionally, the relative water content of drought-stressed leaves pre-treated with H2O2 was higher than that of leaves pr...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...
