Lossless and near lossless compression of images with sparse histograms

Histogram sparseness is an unexpected characteristic by most of the lossless compression algorithms that have been designed mainly to process continuous-tone images. The compression efficiency of most of lossless image encoders is severely affected when handling sparse histogram images. In this paper, we presented an analysis of the histogram sparseness impact on lossless image compression standards and a new preprocessing technique was proposed in order to improve the compression performance for sparse histogram images. The proposed technique takes advantage of the high likelihood between neighboring image blocks. For each image block, the proposed method associates the most reduced set representing its active symbols and makes the histogram dense. This technique proved to be efficient without applying any modification to the basic code of the state-of the art lossless image compression techniques. We showed experimentally that the proposed method outperforms JPEG-LS, CALIC and JPEG 2000 and achieves lower bitrates.
Formation of students' communicative competence based on individually differentiated technology

Introduction. Communicative competence is an integral part of human existence and the main area of professional activity of students – future educational psychologists. Nevertheless, an insufficiently studied issue is the introduction of individually differentiated technologies to improve this process in the practice of vocational training. The purpose of the study is to develop a model of individually differentiated technology for the formation of students' communicative competence and experimentally prove the effectiveness of its implementation in the implementation of professional training of bachelors. Materials and methods. The study involved 168 students of 3-4 courses enrolled in the direction of training "Psychological and pedagogical education" (bachelor's degree). Students of the experimental group in educational and extracurricular activities in the process of professional training implemented the author's individually differentiated technology, and students of the control group used the teaching technologies stated in the work programs of the disciplines. Mathematical and statistical processing of the results obtained was carried out using the Pearson chi-square. Results. The implementation of the individually differentiated technology was based in the theoretical aspect on the synergy of radically differentiated, individually combinatorial and individually modifying approaches, and in practical terms on the training system, including communicative-dialog, activity-oriented and personality-oriented interaction technologies. Significant changes were found for the general cultural (p&lt;0.01), general professional (p&lt;0.05), professional (p&lt;0.05), social (p&lt;0.05), and additional (p &lt;0.01) components. The highest level of effectiveness of the author's development was revealed in the ability of students to work in a team, tolerantly perceive social, cultural, confessional, ethnic and personal differences, and the ability to conduct consultations, professional interviews, trainings to enhance the professional self-determination of students.

New Insights into Image Restoration Using Filter Analysis and Noise Models

Image restoration, by eliminating noise and blur from an image, restores the original image.In certain cases, image blur is inevitable, and to eliminate blur caused by camera shake or radar imaging or to remove the effect of image system reaction, etc.There are many suggested methods for noise removal and our paper will investigate and address various models of noise and blur and methods of restoration.There are numerous techniques developed, the most efficient being the Wiener filter and is the fundamental noise reduction approach.Wiener filters may cause some undesired effects in image restoration (significant degradation in quality).Various techniques and models are approached in the establishment of the power spectrum of noise and undegraded images.In terms of noise reduction and image restoration, this paper studies the Wiener filter's assumption and quantitative performance improvement.The SNR is improved considerably.But noise reduction is directly proportional to image degradation.To counter this, we must have prior knowledge of the original image by some PDF (Probability Distribution Function).

A numerical study of entropy and residual entropy estimators based on smooth density estimators for non-negative random variables

In this paper, we are interested in estimating the entropy of a non-negative random variable. Since the underlying probability density function is unknown, we propose the use of the Poisson smoothed histogram density estimator to estimate the entropy. To study the per- formance of our estimator, we run simulations on a wide range of densities and compare our entropy estimators with the existing estimators based on different approaches such as spacing estimators. Furthermore, we extend our study to residual entropy estimators which is the entropy of a random variable given that it has been survived up to time $t$.
The Seven Time Managing Strategies of English Teachers to Adapt with the Change in Curriculum

The Indonesian school system curriculum was changed from KTSP to curriculum 2013 (K13) since the year 2013. This alteration of the curriculum dealt an impact by changing the allocated time for English classes. Within KTSP, Teachers taught English subject for four hours session per week, which means four times 45 minutes each week, whereas, within the K13, the allocated time for English subject is a two hours session per week which means two times 45 minutes which means there is a reduction in time for English subject. This study aims to determine how English teachers manage their time by conducting interviews, observations, and documentation analysis on 11th grade English teachers at MAN 1 Pasaman, Indonesia. Findings revealed seven strategies, namely following the school calendar, setting goals and working on achieving those goals, prioritizing the more important goal, making a daily schedule of classroom activities, making a to-do list, setting a time limit for the task in the classroom, and utilising transition time effectively. The findings are a novelty because few studies have identified the specific strategies that English teachers used to successfully adapt to the curriculum change. Thus, this study contributes to future educators preparing and anticipating possible curriculum changes that may drastically change teaching time.
Modelling of Solar Spectral Radiation in Penang Island on a Digital Elevation Model

Interest has been increasingly focused on the studies of solar radiation across the globe ever since people are more concern about energy conservation. Due to the increment of terrestrial application of solar energy, the scientific interest on solar distribution has expanded from broadband solar energy to its spectral distribution. Measurement of solar radiation with its spectral profile provides knowledge for making important decisions involving resources and energy, agriculture and climate. In remote sensing, the measurement of spectral solar radiation is important for sensor calibration and image enhancement to extract the most information out of a satellite image. The spectral radiation can be measured using spectral radiometer specifically design for measuring solar radiation; however such instruments are expensive and only provide point data which is very limited in most studies. This study aims to provide a rigorous spectral radiation model that predict the spectral solar irradiance in temporal resolution of every minute with spectral range from 350nm to 2200nm under cloudless condition. The parameters used in this model include the distance between sun and earth, time, coordinate, atmospheric interference and terrain effect. Atmospheric sounding data was used in this study to provide the necessary atmospheric parameter in the simulation of solar propagation through the atmosphere. The atmospheric effects considered in this study include Rayleigh scattering, aerosol attenuation and the absorption of water vapor, ozone and uniformly mixed gas. The simulation results were projected onto a digital elevation model to further calculate the effect introduced by the topographic variation and to get a three dimensional solar spectral radiation. The result obtained from this study is compared with spectral solar irradiance data collected during the month of June and July, 2018 with root mean square deviation of 9 watt per meter square at the wavelength of 350nm to 2200nm.Â Â

The data in this study were the occurence of altruism aspects in English teaching and learning classroom activities. This study employed two instruments in collecting data, namely observation and interview. This study revealed that three aspects of altruism, empathy; prosocial behavior and aversive-arousal reduction appeared in English teaching and learning classroom activities and the most dominant is prosocial behavior. In other words, it can be concluded that MAN Karawang has contributed in altruism praxis in English teaching and learning classroom activities. The contribution is shown by habituating and maintaining the behaviors that represent aspects of altruism, such as Student follows teacher`s instruction; Student lends others stuffs they do not have and student uses positive language during discussion.
The Case for Eight Igbo Tones

Despite research findings to the contrary, many still regard Igbo as a two-tone language, with some recognizing an additional third tone. However, this simplified two-tone system (or two-plus-one system) does not tell the full story of Igbo tones or reflect all the research in Igbo linguistics. Tone testing using a soundboard reveals eight tones (four long and four short ones) which occur in the default pronunciation of common Igbo words and which every Igbo speaker uses frequently. An eight-tone system for individual words better explains the complexity of Igbo tonality and reveals interesting possibilities about the evolution of the Igbo language and its relationship with other tonal languages, such as Chinese. Keywords: Igbo, tones, Chinese DOI: 10.7176/JLLL/76-04 Publication date: February 28 th 2021

An Emerging Secure and Expressive Data Access Control for Cloud Storage

Secure cloud storage, which is an emerging cloud service, is designed to protect the confidentiality of outsourced data but also to provide flexible data access for cloud users whose data is out of physical control. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is regarded as one of the most promising techniques that may be leveraged to secure the guarantee of the service. However, the use of CP-ABE may yield an inevitable security breach which is known as the misuse of access credential (i.e. decryption rights), due to the intrinsic “all-or-nothing” decryption feature of CP-ABE. In this paper, we investigate the two main cases of access credential misuse: one is on the semi-trusted authority side, and the other is on the side of cloud user. To mitigate the misuse, we propose the first accountable authority and revocable CP-ABE based cloud storage system with white-box traceability and auditing, referred to as CryptCloud+. We also present the security analysis and further demonstrate the utility of our system via experiments.
