On the Design and Construction of a Dual Axis Solar Tracker Prototype for a Dish Concentrator using ATMega3298P Microcontroller

The desire for reliable power supply is the reason for further research into alternative sources of power.Although solar tracking is not a new technology, yet solar harvesters still suffer low efficiency due to the intermittence of solar insolation.Thus many smart systems have been designed to maximise solar harvesters.Among the systems is the dual axis solar tracking system.For demonstration of the tracking system, a prototype was developed as a model for a conventional tracking system.It met its objective of tracking solar irradiance and accordingly re-orient the payload in real time to the point of maximum solar insolation.Testing and observation using the developed prototype gave evidence to the fact that solar trackers can increase the efficiency of solar harvesters.The results showed steady solar tracking for 6 h starting from 9:00 am-3:15 pm.The sensitivity of the sensors allow the system to track solar insolation as low as >5 lumen.The entire system was powered by 5 volts which made it energy efficient and can be run at low cost.
An efficient matching method in adaptive fringe-pattern projection for surface measurement

Adaptive fringe-pattern projection (AFPP) method is an improvement of fringe projection profilometry (FPP) technique. AFPP method avoids image saturation via reducing the intensity of projection pixels which are corresponding with the shiny areas of the object. To enhance the efficiency of the method, in this paper, we proposed an improved AFPP method that reduces the number of patterns to be projected in preliminary steps. In our proposed method, we introduce epipolar constraints when we match the corresponding pixels between the projector and camera images. We only need to project one direction of phase-shifting fringe patterns instead of two directions, so that the time consumption is reduced by at least half in preliminary steps. The experiment result shows that the proposed matching method guarantees the matching accuracy, and the measurement results are more complete via the improved AFPP method.

An Investigation of Errors Committed by the Students of English Language Teaching Department in Writing Narrative Text

In the EFL context, an error analysis is a paramount study. This type of research might bring many advantages to the success of the teaching and learning process itself. This study investigates the types and causes of student errors in writing a narrative text. Furthermore, this research provides several suggestions for decreasing the occurrence of the errors. The research method employed was descriptive qualitative, and the researchers completed this study through several phases called data gathering, data analysis, and data presentation. The data analysis reveals several significant findings. First, there are six types of errors that emerged called the use of tenses, the use of articles, the use of relative pronouns, mistyping, confusing words, and agreement of singular/plural nouns. Second, the interlingual transfer is the most significant factor causing errors. Third, decreasing the errors might be done by paying more attention to global errors, the errors with high frequency, the most influential error type, and the most problematic topic. In this present study, the kind of error requiring more attention is English tenses, and one of the suggested solutions for teaching tenses well is using attractive teaching media such as English songs. Applying effective ways of teaching is an alternative to reduce student errors.
Deep Learning for Language and Vision tasks in Surveillance Applications

The keyword spotting and handgun detection tasks have been widely used to manipulate devices and monitor surveillance systems in a more efficient manner. In spite of the advances of deep learning approaches dominating those tasks, the effectiveness of them is mostly tested and evaluated in datasets of exceptional qualities. The aim of this paper is have an study about the performance of these tools when information captured by common devices are used, for example; commercial surveillance systems based on standard resolution cameras or microphones from smartphones. For this we propose to build an audio dataset consisting of Speech commands recorded from mobile devices and different users. In the audio section, we evaluate and compare some state of art keyword spotting techniques with our own model, which outperforms the baselines and reference approaches. in this evaluation obtained an accuracy of 83\% in accuracy. For the handgun detection, we did a fine tuning of YOLOv5 to adapt the model and perform the detection of handguns in images and video. This model was tested on a new dataset that uses labeled images from commercial security cameras.
Communication Technology for Voice Emotion Detection Based on Hybrid Deep Learning Method

Voice is an important way to express emotions, while the emotive information contained in the voice under natural and performance state is not identical. To explore the differences between vocal emotion tests under natural and performance state and to improve the accuracy of intelligent vocal emotion test system, a kind of vocal emotion test model based on the feature representation of deep learning CNN(Convolution Neural Network) is put forward. With Lenet－5 model as the foundation, a convolutional layer and a pooling layer are added to the above convolution model, meanwhile the two-dimensional convolution kernel is changed into a one-dimensional one, which is conveyed to the above model after pre-processing the one-dimensional features, representation of the features is completed, and finally sentiment classification is realized through a SoftMax classifier. It is indicated in the experimental results that the emotion recognition rate under natural state is obviously higher than that under performance state, meanwhile misclassification rate of anger and sadness under both states is also found.
"To think with not one head": Tanga’s Book

The Book of Tanga is talked about by philosopher Konstantin Pavlov-Pinus and Vladimir Rokitiansky who has composed the book and was “the other one” in their long dialogue. “Tanga” (Tatiana Olegovna Lubimova, 11.01.1971 – 12.04.2017) as she is seen in the book is a methodologist (in the tradition of G.P.Schedrovitsky) but also a poet and artist, an observer of transitory life, a dreamer, who values loneliness, and an emergency which is always ready to help a person who suffers. The Book of Tanga consists of her postings in the livejournal – her thoughts and discussions thereof, dream records, pictures of what has been seen in the window or on the way, impressions from poetry and prose of favorite authors, as well as of reflexive reports of verbal workshops (“thinking with not one head” as she put it – mainly with V.Rokitiansky, aka Gignomai) and of their correspondence. The purpose of the Book is to revive the image of a Person Tanga. For the composer it is a possibility to continue the unfinished co-thinking and dialogue; for a reader – a possibility to join this dialogue and this collective thinking.
The Impact of High School Program Reform on First-Year University Studentsâ€™ Academic Performance. Case Study: Biology

The student transition from high school to university is a complex process in which various factors operate. One of these factors is the degree of the studentsâ€™ academic preparation in certain subjects. This article analyzes the impact of this factor on the studentsâ€™ success in the first year of university studies, in the conditions when the subject program in high school has been reformed. This impact on the studentsâ€™ success, which is expressed both in the degree of academic preparation and in the studentsâ€™ attitude in the relevant subject, has been assessed employing statistical analysis. The analysis covers a period of 3 years (2017-2020), and is based on a sample of first year students of the Bachelor degree in Biology. The results of the questionnaire, conducted with first year university students, show the impact of their high school academic preparation on the success they have in the first year of university. This success is measured by assessing the change in average grade and their pass rates. Evidence of the impact of this factor in teaching has helped to know in detail these intermediate phases of this process. The built model makes it possible to analyze the impact of the high school curriculum reform on the studentsâ€™ success, creating the opportunity for further improvements. Despite the fact that the object of the study is the Biology curriculum and the evaluation of the impact in academic success of students who graduated from high schools where a competence based curriculum was implemented, this methodology can be used for the study in other subjects, especially life sciences.

A Survey on Various Cryptanalytic Attacks on the AES Algorithm

The Advanced Encryption Standard (AES) Algorithm is popularly being used for securing classified information of Military and Banking services. This has led to intensifying the research on various attacks on AES algorithm either to test the security of the algorithm itself or to obtain the secret information i.e. the key. The AES algorithm is constantly subjected to various cryptanalytic attacks since its release in 2001. However, most of these attacks are theoretical and have been incapable of breaking the AES algorithm completely. These attacks are performed on the reduced rounds of the AES algorithm are compared with the brute force attack for time and data complexity. The brute force attack tries all possible values of keys and is the most effective technique of cryptanalytic technique. This research paper presents an extensive survey on various existing cryptanalytic attacks on the AES Algorithm.

An Overview of the Foundations of the Hypergroup Theory

This paper is written within the framework of the Special Issue of Mathematics entitled “Hypercompositional Algebra and Applications”, and focuses on the presentation of the essential principles of the hypergroup, which is that the prominent structure of hypercompositional algebra. Within the beginning, it reveals the structural relation between two fundamental entities of abstract algebra, the group and therefore the hypergroup. Next, it presents the several sorts of hypergroups, which derive from the enrichment of the hypergroup with additional axioms besides those it had been initially equipped with, alongside their fundamental properties. Furthermore, it analyzes and studies the varied subhypergroups which will be defined in hypergroups together with their ability to decompose the hypergroups into cosets. The exploration of this far-reaching concept highlights the particularity of the hypergroup theory versus the abstract pure mathematics, and demonstrates the various techniques and special tools that has got to be developed so as to realize results on hypercompositional algebra.
Simulated acoustic characteristics of stage displacements in a shoebox hall: the Cultural Centre Concert Hall in Taipei

Since the opening of the Berlin Philharmonic Hall in 1963, the surround configuration has been preferred and used worldwide by architects because of its dramatic visual appearance and the proximity of the audience to the stage. However, according to a study by Beranek, the three most highly rated concert halls in the world for acoustics have a shoebox shape. The aim of this study, therefore, was to study the acoustic characteristics of stage displacement in a shoebox hall. A simplified wire-frame model of the Cultural Centre Concert Hall in Taipei, Taiwan was used as a case study. This stunning performing arts building has a seating capacity of 2077 and a shoebox configuration. Five different stage displacements along the central axis were proposed. The original ceiling configuration was used and moved with each stage displacement. Fixed materials and their relevant absorption coefficients were also used in the study. Acoustic parameters were simulated. The results showed that, for the best audience distance to the stage the simulated T30 increased to approximately 0.45 seconds at 1000 Hz. To meet the original T30 design goal of 2.45 seconds at 1000 Hz, approximately 200 m2 of 0.90 NRC acoustic wall panels were installed.

A Dynamic and Highly Configurable Crypto-Processor for brief communication interval

In modern computing systems data security is of paramount importance. The data transfer must be made secure because it can be significantly sensitive for any organization involved. This paper expounds a SOC architecture to facilitate end to end secure data exchange for applications involving short communication intervals. This SOC has been designed to behave as a co-processor which along with a standard general-purpose processor would serve as a cryptosystem. The SOC employs two famous algorithms – RSA and AES for cryptography. In contrast to usual single key cryptographic systems, this paper tries to elaborate an innovative methodology involving dynamic security measures that makes the system distributed rather than making it central to a specific algorithm and hence a particular key. The methodology involves generating and using an AES key for data encryption and RSA key for secure transfer of the AES key between the point of transmission and reception.
