Education, i.e., the backbone of a nation, encompasses a variety of role players and stakeholders among which students are, perhaps, the most important one. However, analyzing students' feedback on institutional education system from a macro level is yet to be done in the literature. To address this issue, in this paper, we conduct a study on different perspectives of institutional education based on students' feedback. Here, we mostly focus on the institutional education in Bangladesh. Our study is based on the data collected from the students through both on-line and offline surveys. We analyze the collected data to dig out various key aspects such as appropriateness of educational contents, relationship between teachers and students, and extents of malpractice in the institutional education. Additionally, we attempt for identifying different personalities who exhibit significant influence on the students. Our study reveals a number of key findings that may facilitate effective reformation and enhancement of the current educational system under focus.

The current work blends the different paradigms of Question Answering systems and presents a content-aware hybrid architecture for an open-domain factoid questions. It combines a knowledge-based, information extraction-based and a web-based approach in a pipelined architecture to construct an answer to a question keeping the context and discourse of the question in view. The proposed semantic-aware hybrid architecture was compared with other QA systems designed over standard benchmark data. The work has shown enough potential in terms of accuracy and time domain complexity and can be used effectively as a semantic understanding-based QA system.

Support Vector Machine (SVM) is one of the most popular machine learning algorithms for pattern recognition of a specific dataset. The percentage of accuracy from a defined SVM model greatly depends on the selection of appropriate attributes for SVM model. But the most effective attributes selection for SVM algorithm is one of the most difficult tasks for any kind of data classification. A mathematical model is proposed in this paper through which effectiveness of attributes for SVM model can be calculated. The validity of this SVM model is justified by comparing the effectiveness of a SVM model with the rate of pattern recognition for corresponding SVM model. Linear, Radial Basis Function (RBF), Polynomial Kernel SVM algorithms are used for pattern recognition. The percentage of accuracy of pattern recognition increases with the effectiveness of SVM model. The range of value of effectiveness of SVM model is 0 to

This work attempts to find the most optimal setting for a convolutional neural network (CNN) for Bengali digit dataset classification. Recognition of handwritten Bengali numerals has recently gained much interest among researchers due to the significant performance gain found in the recognition of English numerals using neural network based architecture. In this work, a new dataset of 70,000 samples were created first by taking handwriting of 1750 persons where 982 persons were male and the rests were female. These individual image samples are then converted to grayscale, normalized, inverted and pickled to complete the data preprocessing step. Later this dataset was recognized using several convolutional neural network settings where the most optimal setting being found to be two convolution layer with Tanh activation, one hidden layer with Tanh activation and one output layer with softmax activation. The proposed optimal number of feature maps is (35, 45). The minimum validation error has been found to be 1.22% which is the current best result compared to all other methods in the literature.

E-Service in Bangladesh has become a catalytic agent for empowering additional effective government services. This article investigates issue covering clues on IT policy about the implementation of marketable commercial services as mobile e-services under the boundary expansion issue of large organization like Mobile Network Operator. In Bangladesh, Specialized services are provided by different vendors, where the service quality is always differed, because there is no integration of such collaboration. Operators can play a vital role by enabling the service through Value Added Service (VAS). Users and providers can find solutions that can help to increase penetration of this untouched sector. In this article, we organize some issues, provisioning approximately resilient guideline to the operators, so that operators cannot play monopoly and ensure a healthy competition. It concentrate on the effects of within and between standards race and competition between operators on performance developing and adopting new VAS services like e-health, as swelling of penetration of mobile services. Our empirical exploration provides an indication of introduction of specialized VAS service over Mobile Network, so users of the core services will be migrated to new data services. Finally, the control of the service level agreement of e-services with fair practice of competition among operators to positively change the curve of specialized service penetration is investigated.

Accounting Information System (AIS) is a platform in which the core concepts of accounting, such as, recording, classifying, storing, safeguarding and interpreting data and reporting accounting information are performed by using various standardized and customized software for better financial control. A wide range of accounting software, such as, Tally, Troyee, AccPac, Oracle Applications, SAP, etc. are already being installed by various organizations in Bangladesh. Through this study, we wanted to know the determinants of employees' acceptance of various AIS in Bangladesh, by applying the Technology Acceptance Model (TAM). A total number of 82 employees from four different companies were provided with the structured questionnaires. Finally, 80 questionnaires were accepted and encoded. The results of the study are based on factors, such as, PU, PEOU, ATU, BIU, andPBC as suggested by Davis in his model known as TAM. All variables were analyzed by using SMART PLS, which is a full-flagged Structural Equation Modeling (SEM) tool. The result shows that Perceived Behavioral Control (PBC) significantly affects employees' behavioral intention to use AIS through mediated effect on PU and PEOU. Hence, PBC is acting as a strong antecedent of the latent variables PU and PEOU in Bangladesh.
会计信息系统(Accounting Information System, AIS)是利用各种标准化和定制化的软件，完成会计数据的记录、分类、存储、保护和解释以及会计信息报告等会计核心概念的平台，以更好地实现财务控制。各种各样的会计软件，如，tali, Troyee, AccPac, Oracle Applications, SAP等，已经被孟加拉国的各种组织安装。通过这项研究，我们希望通过应用技术接受模型(TAM)来了解孟加拉国员工接受各种AIS的决定因素。共有来自四家不同公司的82名员工获得了结构化问卷。最终接受并编码80份问卷。研究结果基于Davis在TAM模型中提出的PU、PEOU、ATU、BIU和pbc等因素。所有变量分析使用SMART PLS，这是一个全标记结构方程建模(SEM)工具。结果表明，感知行为控制(PBC)通过对PU和PEOU的中介效应显著影响员工使用AIS的行为意愿。因此，PBC是孟加拉国潜在变量PU和PEOU的强大先行项。

In this work, several heuristics are proposed to assess their effects in path planning for mobile robots in uncertain and dynamic environments. Path planning for mobile robots is a widely used technique where an optimal collision-free path is searched through an environment. It is one of the most important primitives in robotics and is considered to be a hard problem. Since environments may contain static as well as dynamic obstacles, the optimal path must be collision-free. The situation becomes complicated for mobile robots when an environment consists of dynamic obstacles with random velocities and arbitrary directions. Though there have been a lot of research in static environments, concentration given on uncertain and dynamic environments is a few. Our goal is to find a path in such uncertain and dynamic environments considering simulation time and travel-distance. In order to analyze the robustness of our proposed heuristics, we plugged each of these heuristics in several search algorithms. We also compared the performances of these algorithms. Finally, this paper analyzes the effects of the proposed heuristics in path planning in uncertain and dynamic environments which are usual real-word scenarios for mobile robots.

In the real world, books and documents are the sources of knowledge. But this knowledge is only bounded to people with clear vision. Our society includes a group of people who does not have a clear vision or people who are blind. For this group, world is like a black illusion. The shape and structure's information of an object is unavailable to them let alone reading a document. For blind acquiring knowledge by reading documents is cumbersome. Braille is one of the methods which is used to read a book or document. In this method, any document has to be converted to braille format to become understandable to a blind. The problem arises due to the fact that, this is an expensive procedure and many times not available. The solution is rather simple, introduce a smart device with a multimodal system that can convert any document to the interpreted form to a blind. A blind can read document only by tapping words which is then audibly presented through text to speech engine. “Blind Reader” — developed for touch devices which is user friendly and effective interactive system for visionless or low vision people.

Using technology to improve the life-style of people with special needs has become a hot research topic in today's world. The making of a smart device that can solve the communication issues faced by people with autism spectrum disorder(ASD) and disability is presented in this paper. Fueled by the intent of bridging the communication gap between these people and the rest of the world, we have built a small portable radio frequency(RF) communication device using basic electronic equipments that will allow them to stay in close contact with their family members; even if, they are miles apart from each other. A mere push of a button will notify everyone in the family of the current state of mind of the ASD and disabled people. Each button is loaded with a unique message in audio format, ready to be launched off to loudspeakers that will play them as loud as possible. With this project we are aiming to get rid of the communication problems faced by disabled people and thus help them realize that technology can make their lives shine brighter than it has ever before. Our prototype can be used at homes as well as in hospitals, where patients other than disabled people can also find it useful to their needs. Before getting started we did some intensive research on autism on the internet as well as made a trip to a place that schools autistic people. There we learned a great deal about the various methods used so far to educate and nurture them. One of the methods required the teachers to pronounce words slowly and repeat five times, then the students would be instructed to repeat after them, another involves the good old method that utilizes the power of visualization; in other words, seeing and learning.

Ultrasound (US) Doppler spectrograms have been widely used for diagnosing vascular obstructions. This paper presents an Android smartphone based new approach for detecting the blood flow condition based on the US Doppler spectrogram images. A set of 59 spectrograms acquired from a US Doppler system is processed to extract features, and these non-redundant features are fed into a supervised classifier to determine the normal and abnormal blood flow. The classification is performed using the k-nearest neighbors (k-NN), Support vector machine (SVM), Naive Bayes (NB) and Multilayer perception (MLP) based classifiers. The SVM based classifier has shown superior performance, having an accuracy of 86.4 %, with a sensitivity and specificity of 96.4 % and 77.4 % respectively. The complete technique is implemented as an Android application and the results show the efficacy of the presented approach for the automated diagnosis of arterial diseases.

The SVM based classifier has shown superior performance, having an accuracy of 86.4 %, with a sensitivity and specificity of 96.4 % and 77.4 % respectively. The complete technique is implemented as an Android application and the results show the efficacy of the presented approach for the automated diagnosis of arterial diseases.","PeriodicalId":287635,"journal":{"name":"2016 19th International Conference on Computer and Information Technology (ICCIT)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129560790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
