Interest Group Secur., Audit, Control (SIGSAC) Publisher:Association for Computing Machinery, 1515 Broadway, 17th Floor, New York, NY 10036-5701, United States Abstract:Return-Oriented Programming (ROP) is a technique which leverages the instruction gadgets in existing libraries/executables to construct Turing complete programs. However, ROP attack is usually composed with gadgets which are ending in ret instruction without the corresponding call instruction. Based on this fact, several defense mechanisms have been proposed to detect the ROP malicious code. To circumvent these defenses, Return-Oriented Programming without returns has been proposed recently, which uses the gadgets ending in jmp instruction but with much diversity. In this paper, we propose an improved ROP techniques to construct the ROP shellcode without returns. Meanwhile we implement a tool to automatically construct the real-world Return-Oriented Programming without returns shell-code, which as demonstrated in our experiment can bypass most of the existing ROP defenses.

Box 101161, Weinheim, D-69451, Germany Abstract:Hollowing of inorganic nano/micromaterials can be realized by well-known Ostwald ripening and Kirkendall processes. However, hollowing of organic polymer without sacrificial templates is seldom seen. Herein, we demonstrate for the first time that conducting polymer nanofibers can be transformed into nanotubes by a simple, effective, and controllable swelling-evaporation strategy. By controlling swelling degree, surface-patterned poly(o-toluidine) (POT) nanofibers, and nanotubes with controllable inner diameter can be fabricated. Novel characteristics of such nanotubes, such as patterned surfaces and sealed tips, will endow them with enhanced properties when applied in fields as controlled drug delivery, noble metal nanocatalysts supporter, and adsorbent for heavy-metal ions.

With the same design of suction box and discharge passage, the head losses of the outlet discharge passage and the pumping system efficiencies were compared between 2 design schemes of different size and shape of the shaft (pit). The flow conditions of pump, in terms of distribution uniformity of axial velocity and velocity-weighted bias angle of outflow field in the outlet cross-section of suction box, and the pumping system efficiencies were compared between the front and rear arrangement of the shaft while keeping the shaft and the pump unchanged. The computational results show that for the rear arrangement of shaft schemes the size and shape of the shaft affect not only the head loss of the discharge passage but also the pumping system efficiency. If just simply turning the pump around 180 degrees without changing pump and flow passages, the pumping system can be operated both in the rear arrangement scheme of shaft and front arrangement scheme. However, the flow conditions of pump become deteriorated in terms of distribution uniformity and bias angle when the rear arrangement scheme of shaft changed to front arrangement. As a result, the hydraulic losses of suction box and discharge passage in front arrangement increases, the best efficiency point drops and high efficiency zone moves toward smaller flow rates. © 2011 IEEE.

They are widespread used and effective in regulating flow patterns and velocity distributions in forebay and sump, however, the difference affecting flow conditions of pump are never evaluated quantitatively before. In this paper, a series of specially designed "ω" type rear wall, vertical columns and bottom sills with different parameters are placed in different places of the sump in turn while keeping the water levels and pump discharge unchanged. A swirl meter is adopted to measure swirl intensities in the suction pipe of pump, and the effects of different intake design schemes and engineering measures on flow conditions of pump are compared quantitatively in terms of swirl angle. The experimental results show that under certain conditions vertical columns and bottom sills can improve flow conditions, but their design parameters and where they are placed in the sump need to be optimized in order to obtain better results. The "ω" type rear wall with bottom pilot cone can considerably reduce the intensity of swirl in the suction pipe of pump, the mechanism of which needs to be studied extensively. © 2011 IEEE.
