Abstract:QUDA is an architecture similar to CUDA for HPC applications of Quantum GPU architectures to be used in conjunction with GPU and MCU based processing. There is no QUDA pipeline similar to a stream processing architecture or an out of order instruction pipeline. True ILP is achieved with a QUDA architecture, which is better than quasi-parallelism in a CUDA or scalar/vector architecture.Keywords: QUDA architecture, HPC, Quantum Cloud, Qiskit, spin waves, spintronic, hyper-data, quantum operating system.What:Quantum Unified Compute Architecture or QUDA architectures is the use of Q and Qiskit for a reconfigurable quantum array architecture on spintronic units with a reconfigurable scheduler for a quantum operating system.

Preclinical Training

BACKGROUND Preclinical training on manikins is a key component of dental medicine education. Preclinical practice on traditional manikins and real clinical practice shows massive differences. Specifically, preclinical training on traditional manikins is inefficient. OBJECTIVE The aim of this study is to describe a manikin with a multimedia system and evaluate its effectiveness in preclinical dentistry training. METHODS A total of 159 students participated in this study. Amongst these students, 80 used traditional manikins (Group TM) for preclinical practices, including cavity preparation and full-crown preparation, and 79 used a manikin with a multimedia system (Group MM). The cavity preparation scores and full-crown preparation grades of the two groups were compared. The students and teachers completed a final questionnaire survey to evaluate their experience of preclinical practices using the manikin with a multimedia system. RESULTS Group MM performed better than Group TM in the preclinical practices of cavity preparation and full-crown preparation. The final questionnaire results indicated that students in Group MM were satisfied with the clarity, simulation, helpfulness in mastering operation points quickly and improvement in operation proficiency provided by the manikin with a multimedia system. The teachers were satisfied with the teaching effect of the manikin with a multimedia system and had a high opinion of the students’ mastery. CONCLUSIONS The results of this study indicated that manikins with a multimedia system are a good alternative traditional manikins in preclinical dentistry training.

In this chapter, we consider some of the cryptography which can be used to protect data stored on personal devices. We begin by looking at various forms of cryptographic file protection, including full disk encryption. We then consider the cryptography which can be used to support two applications widely used on personal devices, namely, email and asynchronous messaging. To illustrate the latter, we discuss the cryptography deployed by the application WhatsApp. Finally, we obtain a slightly different perspective by providing an overview of the cryptography supported by one particular device platform, Apple’s iOS operating system.

Since Chrome's initial release in 2008 it has grown in market share, and now controls roughly half of the desktop browsers market. In contrast with Internet Explorer, the previous dominant browser, this was not achieved by marketing practices such as bundling the browser with a pre-loaded operating system. This raises the question of how Chrome achieved this remarkable feat, while other browsers such as Firefox and Opera were left behind. We show that both the performance of Chrome and its conformance with relevant standards are typically better than those of the two main contending browsers, Internet Explorer and Firefox. In addition, based on a survey of the importance of 25 major features, Chrome product managers seem to have made somewhat better decisions in selecting where to put effort. Thus the rise of Chrome is consistent with technical superiority over the competition.

In this paper, systolic array-based novel architecture for dual-tree complex wavelet transform (DTCWT) computation is designed and implemented on FPGA. The wavelet filter coefficients of DTCWT are quantized and rounded to nearest integer and the loss in rounding and quantization is limited to 0.5[Formula: see text]dB as compared with software implementation. The parallel architecture designed computes row elements simultaneously and pipelined architecture is designed to compute column elements. The proposed architecture is modeled using Verilog and implemented on Xilinx Virtex II FPGA. For 2D implementation, the design operates at a maximum frequency of 156[Formula: see text]MHz and consumes power less than 3[Formula: see text]W. This is the first design with systolic array architecture on FPGA for DTCWT computation operating at frequencies greater than 100[Formula: see text]MHz.

Although many ways to communicate with someone, SMS is still one of the popular media to send a message to someone. Not unlike the others, the messages sent can be known by the third party either tapping or the investigation. Unencrypted SMS can be easily obtained from communication providers so that they may be misused. Since the communication devices have been using Android operating system, they are programmable. There is various script can be inserted to devices to protect the data. One of them is Vernam Cipher. This method offers how to protect personal messages sent via SMS easily. It converts the message into an encrypted message shortly before sent. At the moment there tapping on the outside, the information is not easily understood its contents. The message is entirely secure.

Graphics Library

With the diversification of terminal equipment and operating systems, higher requirements are placed on the rendering performance of maps. The traditional map rendering engine relies on the corresponding operating system graphics library, and there are problems such as the inability to cross the operating system, low rendering performance, and inconsistent rendering style. With the development of hardware, graphics processing unit (GPU) appears in various platforms. How to use GPU hardware to improve map rendering performance has become a critical challenge. In order to address the above problems, this study proposes a cross-platform and high-performance map rendering (Graphics Library engine, GL engine), which uses mask drawing technology and texture dictionary text rendering technology. It can be used on different hardware platforms and different operating systems based on the OpenGL graphics library. The high-performance map rendering engine maintains a consistent map rendering style on different platforms. The results of the benchmark experiments show that the performance of GL engine is 1.75 times and 1.54 times better than the general map rendering engine in the iOS system and in the Android system, respectively, and the rendering performance for vector tiles is 11.89 times and 9.52 times better than rendering in the Mapbox in the iOS system and in the Android system, respectively.
