a b s t r a c tThe measurement of the diameter change of a piezoelectric transducer (PZT) cylinder with the whitelight interferometry is proposed and experimentally demonstrated. One arm of a Mach-Zehnder interferometer (MZI) is wrapped on the PZT cylinder, and the phase change of the interferogram of the MZI is used to determine the diameter change when a DC voltage is applied on the PZT cylinder. The Fourier transform white-light interferometry is used for recovering the phase change of the interferometer. The experimental results show that the diameter change resolution of 0.8 nm for the PZT cylinder with diameter of 40 mm is achieved.

This paper aims at analyzing paratexts in the translation of the meanings of the Glorious Qur'an entitled Quran: A Reformist Translation by Edip Yuksel, Layth Saleh al-Shaiban, and Martha Schulte-Nafeh. It attempts to explore how the translators exploit paratexts to bring too many ideas unrelated to those implied in the main text but remain blind to illustrate the real intended ones. It seeks evidencing how the translators delude themselves in suggesting that their approach is the only way to read the meanings of the Glorious Qur'an. Furthermore, the paper highlights how paratexts are used for purpose of exploitation instead of exploration. It addresses four forms of paratexts used in the selected data: title of the selected data; preface or prefatory introduction; intertitles; and endnotes. The paper aims at showing how these paratexts affect the way in which the original themes are reframed to make them compatible with the translators' targeted paradigm. Specifically, it describes how the translators combine new innovated concepts with contested ones waging a war on the social, religious and cultural world of all the people who oppose the translators' approach. The present paper addresses how the translators attempt to secure predominance and prevailing influence on minds of the target readers by constructing a number of new frames in the target text driving them to a certain interpretation of the Qur'anic text.

Code-reuse attacks pose a threat to embedded devices since they are able to defeat common security defences such as non-executable stacks. To succeed in his code-reuse attack, the attacker has to gain knowledge of some or all of the instructions of the target firmware/software. In case of a bare metal firmware that is protected from being dumped out of a device, it is hard to know the running instructions of the target firmware. This consequently makes code-reuse attacks more difficult to achieve. This paper presents a novel approach how an attacker can gain knowledge of some of these instructions by sniffing unencrypted incremental updates. These updates exist to reduce the radio reception power for resource-constrained devices. It will be demonstrated how a return-oriented programming (ROP) attack can be accomplished on a MSP430 MCU using only the passively sniffed incremental updates. The generated updates of the R3diff and Delta Generator (DG) differencing algorithms will be under assessment. The evaluation reveals that both of them can be exploited by the attacker and how an attacker can maximize his information gain when dealing with more than one update. It also shows that the DG generated updates leak more information than the R3diff generated updates. This stresses the fact that even delta updates need to be protected with encryption. To defend against this attack, different countermeasures that consider different power consumption scenarios are proposed, but yet to be evaluated.
