The Linklet Project: A Solution to Your Documentation Needs

Abstract: This paper describes about a solution to your pdf and documentation needs on you mobile phone. This is a paper on a mobile app created by Aastha Bhatt, Hrishikesh Kavale, Aditya Pandey and Sunny Manjrekar as our final year project. The name of the app is LINKLET. Converting images to pdf or excel to pdf, scanning of barcodes for invoices or merging or removing pages from pdf is never an easy task. And even if we somehow manage to pull it off the accuracy of such systems is questionable, then again all applications which provide such features are paid. The problem faced by us students during the online system of education is what sparked this project, we were required to scan our assignments, convert them into pdf , receive pdfs from our teachers and modify them or add our documents to them, etc and though all of this is easy on a computer not all students have access to it. Also it is a hassle to search our important documents in the download folder of our phone and present it when required on the spot. So as a solution we have created an app which provides major features like merging of pdf, extract images from pdf, convert pdf to image and image to pdf ,etc. Also providing a feature to store all our important documents in a single place for handy access along with security features like finger print lock. The aim was to create a handy tool for the students to ease their work and an app for everyone to carry their important documents around in a safe and secure manner ready to present when asked by officials anytime anywhere without having the need to carry it on person. The approach we took for this project was a simple one. We asked ourselves and our peers as to what problems we are facing , looked up for online solutions , developed the application by referring various tutorials. The experimental results of the app evidently demonstrate the effectiveness of the proposed system. Keywords: LINKLET, PDF, conversion, document, app.
Students’ Perceptions on Mobile-Assisted Language Learning (MALL) in EFL Class: An Overview of Altissia Usage

Previous research has revealed that MALL are becoming widely used since it can increase students’ knowledge and skills in English language learning. This study aimed to investigate students’ perceptions on MALL, particularly Altissia, in EFL class. Most of students did not use or access Altissia during the learning process was becoming one of the problems that leads to the low ability in students’ English skills. In total, thirty students answered a questionnaire survey after experiencing Altissia in their learning activity. The findings revealed that the students’ agreement to the positive perceptions were showed in the questionnaire prevailed over their disagreement or neutral responses. Altissia contributed great impact on their listening skills and vocabulary knowledge. Altissia also supported them to enhance their motivation and interest to keep learning English. Students felt excited in learning new levels in different topics on Altissia. Students could practice to communicate their English skills more often after learning with Altissia. On the other hand, as the findings also indicated the students did not get any notification related to the study time and they did not experience writing activity on Altissia. Moreover, Altissia can be an alternative learning media that can improve students’ skills in their EFL class.

INTEGRATED LESSONS IN CHEMICAL EDUCATION

The features of integrated lessons in the chemistry teaching process are described in this article. The opportunities of increasing the effectiveness of teaching chemistry are identified on the basis of the highlighted advantages of this lessons’ type teaching. It is shown that an integrated lesson is a specially organized lesson, the purpose of which can be achieved only by combining knowledge from different subjects (biology, physics, mathematics, computer science). It is aimed at considering and solving a problem, allowing to achieve a perceptual, synthesized understanding of the subject under study by students, harmoniously combining the methods of various sciences, having a practical orientation The article provides information that today in chemistry lessons, in addition to the classroom-specific form of organization of the educational process, it is advisable to use non-traditional forms of education, such as integrated lessons. It is shown that any components of the pedagogical process can be integrated in the lesson: goals, principles, content, methods and means of teaching. When, for example, the content is taken, any of its components can be distinguished for integration in it: concepts, laws, principles, definitions, signs, phenomena, hypotheses, events, facts, ideas, problems, etc. It is also possible to integrate such components of the content as intellectual and practical skills and abilities. These components from different disciplines, combined in one lesson, become system-forming, educational material is collected around them and brought into a new system.
Imaginary ethics: The morality of fictional aesthetics in speculative design

To effectively examine the underlying premises of emerging technology has become a major challenge to today’s design ethics. An adequate and prefigurative response to these situations requires a shift towards a fictional aesthetics that calls for co-imagination. Speculative design that sharing a similar ethical mechanism with Jacques Rancière’s aesthetic politics is worthy of attention since the affinity between the literature and emerging designs is becoming manifest. Speculative design embodies its ethical advantage by asking ‘what-if’ questions and providing no answer to keep its prerequisite of equality of intelligence. It devises fictional props and unreal scenarios to distribute the sensible to make audiences notice the possible latent negative social consequences of future technologies. The absurdity in speculative design is what Rancière termed ‘dissensus’, which is the result of fictional aesthetics that aims to inspire reflection and debate on the current state of reality and open the possibility for preferable transformation.

Using Team Building-based Instruction to Foster EFL Learners’ Motivation under the Context of Education 4.0

Under the context of Education 4.0, motivation for language learning takes on a range of meanings and implications that are inextricably bound up with more socially meaningful contexts. Hence, the quality of motivation matters. It is imperative that EFL education make adjustments to strengthen learners’ motivation to achieve the desired learning outcomes and develop skills required in Education 4.0 era. Drawing on interdisciplinary knowledge of applied linguistics and organizational behavioral science, the current research explored the effects of team building-based instruction on EFL students’ motivation. The participants of the study were 84 undergraduate EFL learners at a Chinese university. Questionnaire and open-ended questions were employed to collect data. The results showed that, on average, participants reported high mean values for each of the motivation components, indicating that team building-based instruction played a positive role in motivating most students in the course. Nonetheless, students’ responses towards the components vary significantly, especially for the ‘interest’ scale and ‘usefulness’ scale. Several motivating factors that led to students’ motivation to engage in the course were identified: group dynamics, project design, technology, and assessment. The research concluded that team building-based instruction should take both linguistic factors and non-linguistic factors into consideration to fully motivate and engage students. In the end, the researcher proposed implications for motivational pedagogy and practices.
Probabilistic Seismic Hazard Analysis of the Area of Tajikistan Applied to Seismic Design

In current Probabilistic Seismic Hazard Analysis we analyzed an area and fault models. Shallow crust and deep earthquakes are occurred in the area of Tajikistan, and used two area models for shallow earthquakes and one area model for the deep earthquakes. Additionally, we used so called “Woo’s model” or “point model” which is based on the past seismicity more directly. Six active fault databases for Central Asia and specifically for Tajikistan were used to create the fault model.Software CRISIS2015 and recent Ground Motion Prediction Equations were used in the computation. A grid with 0.1 degree of latitude and 0.1 degree of longitude covered the study area, was created for calculations, and for each 9744 grid points we calculated the spectral accelerations from 0.01 s (PGA) to 3.0s, and for 5 exceedance probabilities in 50 years.For easy application of the results in seismic design, all calculations were made for three values of Vs30, corresponding to 3 categories of the soils in the existing Seismic Design Code in Tajikistan.Special 15 Excel sheets were created for engineers and designers to easy construct the uniform hazard spectra for three types of soil conditions for needed points and exceedance probabilities.

Designing a Steganography System

Information security has had an important position both in history and today. Who had access to this data was as important as the data itself. For this reason, people have developed different methods to transmit data to each other and to ensure that other people cannot obtain this data. Steganography is one of these popular methods today. Different steganography methods have been developed for different data types. In this project, 2 different applications will be developed with the least significant bit (LSB) method applied for image steganography. These applications will encrypt texts to image files and will be able to decrypt the encrypted text from the encrypted image file. Afterwards, these 2 applications will be evaluated in terms of performance.
QLEVR: A Diagnostic Dataset for Quantificational Language and Elementary Visual Reasoning

Synthetic datasets have successfully been used to probe visual question-answering datasets for their reasoning abilities. CLEVR (John- son et al., 2017), for example, tests a range of visual reasoning abilities. The questions in CLEVR focus on comparisons of shapes, colors, and sizes, numerical reasoning, and existence claims. This paper introduces a minimally biased, diagnostic visual question-answering dataset, QLEVR, that goes beyond existential and numerical quantification and focus on more complex quantifiers and their combinations, e.g., asking whether there are more than two red balls that are smaller than at least three blue balls in an image. We describe how the dataset was created and present a first evaluation of state-of-the-art visual question-answering models, showing that QLEVR presents a formidable challenge to our current models. Code and Dataset are available at https://github.com/zechenli03/QLEVR
The Analysis study of EFL College Students' English Writing Using Coh-Metrix

This study conducted a corpus-based analysis using Coh-Metrix to examine the difficulty level of EFL college students’ writing. A total of 294 writing samples written by 94 college students were used for this study. The English writing samples were classified into three groups of high, mid, and low level based on the students’ final test. As for the analysis tool, Coh-Metrix 3.0 was used for lexical, syntactic, and cohesion levels and readability. As a result of the study, there were statistically significant differences among three groups in lexical analysis including descriptive indices and lexical diversity. As for syntactic analysis, there were also statistically significant differences in syntactic complexity and syntactic pattern density except for SYNNP and DRPP. In the case of cohesion analysis, there were statistically significant differences in all indicators in the referential cohesion and LSA except for LSAPP1. Finally, there were statistically significant differences in readability including FRE and FKGL. Based on the results of this study, pedagogical implications on using Coh-Metrix as a useful and evaluation tool on students’ writing and several suggestions for further studies are discussed.
