This paper presents the results of an online survey about perpetual access for electronic serials that have been canceled, have ceased, or have transferred to different publishers. The survey sought to ascertain the true experiences of libraries working to maintain perpetual access. Results indicate a high success rate for providing perpetual access. Results also indicate a lack of standardization for and many challenges to keeping track of and providing perpetual access. A discussion section expands on key findings and the most common obstacles to providing perpetual access.

AbstractWith the development of mobile technologies, voice search is becoming increasingly important in our daily lives. By investigating the general usage of voice search and user perception about voice search systems, this research aims to understand users’ voice search behavior. We are particularly interested in how users perform voice search, their topics of interest, and their preference toward voice search. We elicit users’ opinions by asking them to fill out an online survey. Results indicated that participants liked voice search because it was convenient. However, voice search was used much less frequently than keyboard search. The success rate of voice search was low, and the participants usually gave up voice search or switched to keyboard search. They tended to perform voice search when they were driving or walking. Moreover, the participants mainly used voice search for simple tasks on mobile devices. The main reasons why participants disliked voice search are attributed to the system mistakes and the fact that they were unable to modify the queries.

Abstract Dice must often be removed from their packages and reassembled into more suitable packages for them to be tested in automated test equipment (ATE). Removing bare dice from their substrates using conventional methods poses risks for chemical, thermal, and/or mechanical damage. A new removal method is offered using metallography-based and parallel polishing-based techniques to remove the substrate while exposing the die to minimized risk for damage. This method has been tested and found to have a high success rate once the techniques are learned.

Abstract Atrophy of the upper jaw poses problems for fixed rehabilitation of implants. Of the different management possibilities that have been developed, transzygomatic implant placement is a good option and affords a high success rate. These implants are positioned in zygomatic bone by using 2 possible techniques. We present a 48-year-old woman with severe posterior maxillary atrophy in which the canine and frontozygomatic prominence were used to place 6 anterior and 2 transzygomatic implants by using the sinus slot technique for fixed bridge rehabilitation. The advantages of the sinus slot technique over the sinus window technique are discussed.

Nowadays, production and distribution of digital images has become part of our life. Since digital images, which are important carriers of information, are considered as the concrete proofs of facts in many fields and they can be used as evidence in the courts of law, development of techniques to ensure image authenticity is an active research topic. Copy-move forgery is one of the most common manipulation techniques that are implemented on the digital images, and various techniques have been developed for detection of these kinds of forgeries. JPEG format, which presents the ability of making high rate compression without causing remarkable changes in the meaning of the image, is the most commonly used format on digital images. In this study, the topic of detecting free-form copy-move forgeries on digital images is covered. It has been observed that the developed technique is able to detect the professional forgeries in which the copied region is selected in free-form and which are almost impossible to be detected by human eye, with high success rate, and it is able to give successful results even if the image is exposed to postprocesses such as JPEG compression and Gaussian filtering, which make the detection of forgery harder.
