Identifying structure of genes in Human genomes highly depends upon accurate recognition of boundaries between exons and introns, i.e. splice sites. Hence, development of new methods for effective detection of splice sites is essential. DNA encoding approaches are used for feature extraction from gene sequences, while machine learning methods are used for classification of splice sites using those...
Edutainment systems' Development is well documented in research papers, and its application has satisfying results in several knowledge areas. However, methods for multidisciplinary team management in immersive edutainment systems engineering were not found in the survey made. A qualitative evaluation of immersive edutainment systems' engineering was conducted aiming to achieve grounded theory that...
In this paper, we initiate the study of garbled protocols — a generalization of Yaos garbled circuits construction to distributed protocols. More specifically, in a garbled protocol construction, each party can independently generate a garbled protocol component along with pairs of input labels. Additionally, it generates an encoding of its input. The evaluation procedure takes as input...
Mid-level representations are used to map sets of local features into one global representation for a given media descriptor. In visual pattern recognition tasks, Bag-of-Words (BoW) is one popular strategy, among many methods available in literature, due mainly by the simplicity in concept and implementation. Despite the overall good results achieved by BoW in many tasks, the method is unstable in...
With the development of next-generation sequencing technologies, large number of transcripts has been accumulated in public databases. Long non-coding RNAs (lncRNAs), typically above 200 nucleotides in sequence length, have recently attracted increasing interests because of their important roles in various cellular processes. While it is straightforward to distinguishing lncRNAs from most small non-coding...
In this paper, the principle of normalized minimum-sum (NMS) polar decoding process is explored. It is demonstrated that with one properly chosen parameters for NMS algorithm, performances approach to that of the sum-product (SP) algorithm can be achieved. As well, the complexity reduction is realized by calculating a linear function instead of nonlinear function. Simulation results for successive...
Deep neural networks (DNNs) usually demand a large amount of operations for real-time inference. Especially, fully-connected layers contain a large number of weights, thus they usually need many off-chip memory accesses for inference. We propose a weight compression method for deep neural networks, which allows values of +1 or −1 only at predetermined positions of the weights so that decoding using...
High Efficiency Video Coding (Hevc), the newest video encoding standard, provides up to 50% bitrate savings compared to the state-of-art H.264/AVC standard for the same perceptual video quality. In the last few years, the Internet of Things (IoT) has become a reality. Forthcoming applications are likely to boost mobile video demand to an unprecedented level. A large number of systems are likely to...
The Post-HEVC is the emerging video coding standard beyond the High Efficiency Video Coding (HEVC) standard. It is more complex in transformation and prediction steps but it offers the opportunity of 3D and 360° videos coding and compression. This paper presents different statistical analyzes of Post-HEVC encoded videos especially analysis on 1D and 2D transformation types and analysis on intra and...
This paper presents a real-time Kvazaar HEVC intra encoder for 4K Ultra HD video streaming. The encoder is implemented on Nokia AirFrame Cloud Server featuring a 2.4 GHz dual 14-core Intel Xeon processor and Arria 10 PCI Express FPGA accelerator card. In our HW/SW partitioning scheme, the data-intensive Kvazaar coding tools including intra prediction, DCT, inverse DCT, quantization, and inverse quantization...
The naming of local variables is usually at the programmer's discretion. Thus, there is a diversity in naming local variables and this may cause variations in the code quality. Many coding conventions say that the name of a local variable can/should be short. This paper focuses on such conventions, and aims to explore the trends of local variables' names in Java and examine if abnormal local variables...
Encryption is often not sufficient to secure communication, since it does not hide that communication takes place or who is communicating with whom. Covert channels hide the very existence of communication enabling individuals to communicate secretly. Previous work proposed a covert channel hidden inside multi-player first person shooter online game traffic (FPSCC). FPSCC has a low bit rate, but it...
In wireless coded cache network, data contents are cached in a number of mobile devices using an erasure correcting code, and a user retrieves content from other mobile devices using device-to-device communication. In this paper, we consider the repair problem when multiple devices that cache data contents fail or leave the network. By exploiting the wireless broadcast nature, we formulate the repair...
The necessity of performing multispectral and hyperspectral image compression on multicore processor devices running on-board satellites has increased as spectral remote sensing devices produce a high amount of data. Multispectral and hyperspectral instruments acquire images that need compressing before being sent to Earth, because the bandwidth used for transmitting images is a limited resource....
Peer code reviews are important for giving and receiving peer feedback, but the code review process is time consuming. Static analysis tools can help reduce reviewer effort by catching common mistakes prior to peer code review. Ideally, contributors would use static analysis tools prior to pull request submission so common mistakes could be addressed first, before invoking the reviewer. To explore...
To solve the problem of performance appraisal of SME (Small and medium-sized enterprises) s' designers, this paper proposes a design method of appraisal system combining with product data management (PDM) workflow management. Designed a performance appraisal system model based on process management; taking into account the characteristics of supporting businesses, introduced a workflow template customization...
This paper describes experimental evaluations of encoding parameters that are appropriate for MPEG-4 Audio Lossless Coding (ALS) to compress high-resolution audio. MPEG-4 ALS Simple Profile defines the values of encoding parameters, such as the maximum sampling frequency and quantization bit depth, for making it easier to implement in the receiving applications. However, ALS Simple Profile does not...
To satisfy the requirements of complex distributed power electronic system (PES) communication, this paper has proposed a single optic-fiber link data communication protocol based on the Manchester code due to an vacancy in the commonly-adopted protocols, analyzed the encoding and decoding principle of Manchester code, defined the formats of command frame and data frame, calculated the communication...
Modern healthcare service records, called Claims, record the medical treatments by a Provider (Doctor/Clinic), medication advised etc., along with the charges, and payments to be made by the patient and the Payer (insurance provider). Denial and rejection of healthcare claims is a significant administrative burden and source of loss to various healthcare providers and payers as well. Automating the...
