Mostly in many business cases, sales prediction plays an important role. Production planning is a good example. One aspect which affecting sales forecasting is promotion schedule. Since using promotion is commonly done nowadays, especially in internet business, it is hardly seen a day without promotion in Indonesian e-commerce. Thus, this study discusses about forecasting future sales based on promotion scenario data with main objective is to discover the best machine learning algorithm and model to forecast future sales. Promotion mechanism which employed in this study are price cut, buy 1-get 1, and product bundling. We use 577 data from January 2018 to July 2019 as dataset. We compare kNN, GLM, and SVR as the model predictor to forecast number of transactions in a day. From the experiment k-NN yielded the highest performance ability with squared correlation of 0.938. the worst model predictor for this case is GLM with squared correlation of 0.507. We also determine the best parameter input for each parameter using grid optimization method. We discover 2 is the best k value of kNN and Manhattan distance is the best distance calculation for this case

Data mining is one of the most valuable tools for several applications, especially in banking sector. It can be used in risk analysis of loans, detecting fraud in real time and classifying customers’ interests for retention and services purposes. The main objective of this research is to develop a predictive model that can expect the closure status of returned cases in Qatar. This would be of valuable help for the banking sector as well as The Ministry of Justice. The banking sector aims at anticipating when the check will be paid and the Ministry of Justice holds the burden to assign more judges to look into cases of this kind. To produce the predictive model, four-year worth of data (2014-2017) on returned checks as registered at the Police Criminal System in The State of Qatar were obtained. The data was first cleaned from improper input and the attributes collected were reduced from 16 to 10 eliminating those with the lowest to no correlation. Seven classifiers were used in Python code to generate the prediction model: Random Forest (RF), Gaussian Naive Bayes (NB), kNearest Neighbor (KNN), Logistic Regression (LR), Decision Tree Classifier (CART), Linear Discriminant (LD) and Support Vector Machine (SVM). The evaluation of the classifiers was based on three main criteria: accuracy, running time and memory usage. The results show that SVM was not able to converge to any output while RF was the most accurate with 84.4%. Moderate performance in all three criteria was obtained by KNN and LR classifiers, while CART had the second best accuracy with moderate running time and memory usage. It was also found that the size of dataset and the correlation between attributes hugely affect the performance of each algorithm. Moreover, a logarithmic correlation between the accuracy and running time of the classifiers was obtained with R2 of 0.94. To this end, several recommendations for future work have been proposed to facilitate the use of such predictive models with high confidence in Qatar

Minimum Variance Distortion less Response (MVDR) algorithm is the key adaptive beamforming algorithm in high resolution Medical Ultrasound Imaging systems. MVDR Beamformer is a frequency domain beamformer, and each frequency sub band need to be processed to generate covariance matrix and the same is computationally costly. Though many VLSI architectures have been proposed for MVDR Beamformer, currently no Complex Correlation matrix generation architecture for frequency sub band has been devised which supports real time implementation of broad band MVDR Beamformer for Medical Ultrasound Imaging. In this paper we show real time MVDR sub array, sub band processor realization for an array with number of elements N=32 and sub array length L=8. To satisfy the narrow band condition of the array we employed 1K point FFT, with 12.5 % overlap. The entire design of MVDR Sub band processor is tested on the Field Programmable Gate Array (FPGA) platform. The implementation results show that the through put of the developed architecture is 600K Complex Correlation matrix generation per second which is equivalent to 65.57 fps to image a 20cm depth target at a Pulse Repetition Frequency (PRF) of 4 KHz, 600 Field of View and 10 lateral resolution and makes the MVDR a viable solution for practical systems.

Particulate matter is an air pollutant consistent of very small particles that are suspended in the air. Shortterm exposure may result in respiratory symptoms such as shortness of breath, throat and nose irritation, chest tightness, coughing, in addition to eye irritation. The research aimes at creating a prototype of a mobile sensor system that can be used to analyze the particulate matter pollution on a location and on a time scale to measure the degree of pollution in the city. The engineering requirement to construct the edge device includes temperature (humidity) sensor, particulate matter sensor, GPS module, and an LCD for displaying the current sensor values. The health data of the mobile edge device can be analyzed through a developed analytics system, which allows the user to identify and avoid pollution sources. For the implementation of the web service the framework ReactJS, NodeJS with Express.js, and the database MongoDB are being used. The mHelath service is evaluated through field trials: New Year’s Eve, various source identifications, and a demonstration through a journey from the subway station to the university. The paper outlines a mHealth service, which can collect data records of the surroundings and analyze the particulate matter in an information system to visualize risk locations of a user.

Undoubtedly, Mujahidin and later the Taliban have made the situation miserable for women. But, comparatively, women in Afghanistan did not face as many cruelties earlier during Taliban regime as they suffering today. They were secured, honored and allowed to participate equally in all spheres of life ranging from socio-economic to religio-political during the reign of Taliban. Majority of the religious elite among the Muslims interprets the religious teachings according to its own requirements to assure legitimacy particularly in the context of women. Same is the case with Afghanistan, which, being the buffer state, had been remained epicenter for political interests of world powers and who used its soil to expand or legitimize their authority, violate human rights specifically women as wartime strategy to achieve the goals. This intricate study with reference to the manipulated status of women is based on qualitative method and will explore the political dimensions where women have been used as wartime strategy to legitimize the power. It is based on explanatory and exploratory goals of the study. The thematic and observational approach will be used to analyze the available qualitative data by using secondary sources.

Psychological Dimension and Relevance of Nigerian Educational Policies: Parent’s Perceptual Approach
Authors: Ganagana Tony
Published: June 2021

The paper explored the depth of psychological content that can be found in the Nigerian educational policies formulated over the years, and its relationship with their relevance to the needs of the people. To ascertain this parental responses of how they perceived the effectiveness of each of the educational policies they have witnessed from the colonial days to the presence were obtained. Parents who were between 55 years and 80 years were used in the study. Sample size was three thousand, two hundred and sixteen parents. They were to complete a rating scale entitled Educational Policy Psychological Rating Scale (EPPRS). Reliability coefficient of the instrument was 0.76. Being historical in design, data was analyzed with descriptive statistics. Findings revealed that the psychological contents (dimensions) of all the educational policies formulated so far in the country was low (Mean points < 50) and that the Pre-independence Educational Policy had the highest psychological elements (MP > 50). The psychological dimension as provided for in most of the Nigerian educational policies is grossly inadequate for policy effectiveness. It was further discovered  that those educational policies that possessed low psychological background (dimension) also had lowered degree of relevance in addressing the needs of the people. Since psychological dimensions closely impinges on policy relevance, it was  recommended among others that one of the emphases in developing educational policy is the provision of a rich psychological background in the policy.

Understanding one’s rights when arrested and detained: An assessment of language barriers that affect comprehension
Authors: Carney Terrence R
Published: June 2021

Difficult text formulations, on the one hand, as well as poor linguistic skills and comprehension on the other, can severely hamper the communication effort of basic human rights during the judicial process. The rights entrenched in s 35 of the Constitution of South Africa (Act 108 of 1996), as they apply to individuals who are arrested, detained and accused, and read out by a member of the local South African Police Service (SAPS), are written in a legal register that can be too difficult for additional language speakers to understand. This begs the question of whether arrested, detained and accused individuals are fully aware of their rights and whether they can exercise these rights if they do not understand the language that expresses them. This article appraises the potential comprehensibility of the notice of rights (SAPS 14A), as provided to arrested, detained and accused individuals by the SAPS. The researcher’s assessments indicate that the text is pitched at an English readability level suited to university graduates and could be too difficult for South Africans with limited schooling and linguistic abilities to comprehend. A revision of SAPS 14A is offered as an illustration of a possible improvement to increase readability and, subsequently, better access to the mentioned rights.
Demeanour, credibility and remorse in the criminal trial
Authors: Olaborede Adebola , Meintjes-van der Walt Lirieka
Published: June 2021

This article, referring to South Africa as well as to selected other common law jurisdictions, proceeds from the premise that it is a well-accepted practice for judges to consider demeanour in assessing the credibility of a witness and in assessing whether the accused shows remorse when decisions regarding sentences are taken. However, the article also takes cognisance of the fact that there is a lack of generally agreed-upon objective methods for the identification of remorse. The article was prompted by recent health precautions regarding the mandatory use of face masks, in order to protect people and to contain the spread of the coronavirus, which provides an opportunity to review demeanour in general and perceptions concerning facial demeanour or facial expressions in the courtroom, in particular. The article explores the validity and reliability of findings on remorse and of making credibility assessments based on demeanour evidence. Part 1 of the article is an introduction. Part 2 of the article provides a brief overview of credibility and demeanour evidence in the courtroom. Part 3 of the article examines remorse and demeanour evidence in criminal trials. Part 4 of the article considers demeanour evidence as a ‘tricky horse to ride’. Part 5 of the article provides a discussion of empirical research studies in the field of social psychology relevant to the reliability of finding credibility and remorse on the basis of demeanour evidence. Part 6 briefly discusses COVID-19 face-covering regulations and demeanour evidence in the criminal trial. The article emphasises that although non-verbal cues could be valuable to judges, such evidence may be unreliable and that courts have cautioned against demeanour evidence being afforded undue importance. The article concludes that even when facial expressions are available to the court, it would be in the interests of justice to exercise great care concerning demeanour in general and facial expressions in particular as a guide to assessing credibility and the existence of remorse.

Published: June 2021

Short URLs have become commonplace. Short URLs, which are especially popular in social networking services, have witnessed a significant increase in their use in recent years, largely due to Twitter's restriction on message length to 140 characters. We рrоvidе a first сhаrасterizаtiоn in the usage of short URLs in this рарer. Our specific goal is to create a system architecture for short URLs and have an optimized solution of how to use them and as well as their potential impact on web performance. Our project is made while keeping in mind that the generated URL has to be one third the size of a given url. This allows the user the functionality to share the URL with multiple individuals. Our system also incorporates the idea of tracking each individual shortened URL by the usage of a short code. It gives the user the control over their generated URLs.
