BACKGROUND Internet can serve in opening the door to a brand new world of high quality medical information. However, the chaotic size of data available in the WWW is often misleading. We sought to provide the world medical community with a web portal that may be used as a clearinghouse providing the outlet for dissemination of high quality WWW educational products. METHODS Directories of the ...

Convolutional neural networks (CNNs) are the core of most state-of-the-art deep learning algorithms specialized for object detection and classification. CNNs are both computationally complex and embarrassingly parallel. Two properties that leave room for potential software and hardware optimizations for embedded systems. Given a programmable hardware accelerator with a CNN oriented custom instr...

Customizable/extensible processors can be tuned to exploit applications of interest in modern platform-based design. However, in most cases they are implemented as extensions of legacy architectures, a policy that poses significant limitations to achieving high performance improvements. In this paper, the paradigm of the contemporary ByoRISC processor family is presented. The ByoRISC specificat...

Virtual machines have been widely adapted for high-level programming language implementations and for providing a degree of platform neutrality. As the overall use and adaptation of virtual machines grow, the overall performance of virtual machines has become a widely-discussed topic. In this paper, we present a survey on the performance differences of the two most widely adapted types of virtu...

l2 research has shown that instruction in l2 pragmatics is necessary. the current study evaluated the impact of explicit instruction on efl learner's awareness and production of three speech acts of request, apology, and complaint. it also probed whether learners’ language proficiency plays any role in incorporating pragmatic instruction into the l2 classroom. iranian undergraduate students maj...

Due to the increasing number of processors which are integrated in System On Chips (SOCs) the need for robust, highly configurable processors emerged. Preliminary research showed that commercial processors are not suited for many research projects due to the fact that they are closed source and they can not be modified. Open source processors on the other hand appeared to be of too low quality....

the use of multiple implants in the same jaw requires a detailed knowledge of abutment angulation. the position and angulation of the abutments play an important role in treatment planning and fabrication of the custom tray. therefore diagnostic casts that contain cover screws may cause problems during implant therapy. the current article describes a technique for making a preliminary cast with...

Secure communication over public networks like the Internet requires the use of cryptographic algorithms as basic building blocks. Most cryptographic workloads pose a considerable burden on devices like PDAs, cell phones, and sensor nodes, which are limited in processing power, memory and energy. In this paper we present an approach to increase the efficiency of 32-bit processors for handling s...
