Intracranial haemorrhage can be life threatening. Timely detection of acute intracranial haemorrhage in an emergency room is essential so that the patient can be given medical attention without delay. this has led to the use of computeraided Detection (CAD) systems which can help to pick up and prioritize patients with high risk of bleeding. A CAD for identification of acute intracranial haemorrhage in Computed Tomography (CT) on a per patient basis was developed in this project. the CAD is aimed to be a triage tool which determines the priority of image being read by radiologists. It was developed and validated using 119 and 108 volumes of brain CT images respectively. the volumes were first registered to standard Montreal Neurological Institute (MNI) space. Slices close to the base and top of the skull that tend to contribute to false positives were omitted. then, the volumes were analysed by a fully automated CAD program developed in MATLAB. the algorithm involved multiple thresholding and symmetry detection in 3D to detect acute intracranial haemorrhage. the evaluation took around 5s per volume. On a per patient basis, the CAD achieved sensitivity of 75.0%, specificity of 83.8%, and accuracy of 80.6% in the validation set.

Withthe population aging approaching, the life of the elderly has been paid more and more attention. the actual needs of the elderly are the starting point for the design of the clothing of the elderly. Ergonomics is an important means of coordinating the relationship between people and products, which helps humans to find the most suitable design for people's way of life. Clothing is the first in terms of food, clothing, living and traffics. In the design, the use of ergonomic principles can make clothing products more closely suited to the physiological structure of the elderly, in line withthe living habits of the elderly. the experience of the elderly is the key to judge the quality of the clothing product design of the elderly. therefore, the purpose of this study is to analyze the psychological and physiological needs of the elderly, and provide practical reference for the design of clothing styles for the elderly. through data measurement and interview inquiry, the use of ergonomic principles, we can optimize the details of the design of clothing products for the elderly and provide the latest reference for the dimensional span positioning of older clothing styles.

While software refactoring is considered important to manage software complexity, it is often perceived as difficult and risky by software developers and thus neglected in practice. In this article, we present refacTutor, an interactive tutoring system for promoting software developers' practical competences in software refactoring. the tutoring system provides immediate feedback to the users regarding the quality of the software design and the functional correctness of the (modified) source code. In particular, after each code modification (refactoring step), the user can review the results of run-time regression tests and compare the actual software design (as-is) withthe targeted design (to-be) in order to check quality improvement. For this purpose, structural and behavioral diagrams of the Unified Modeling Language (UML2) representing the as-is software design are automatically reverse-engineered from source code. the to-be UML design diagrams can be pre-specified by the instructor. To demonstrate the technical feasibility of the approach, we provide a browser-based software prototype in Java accompanied by a collection of exercise examples. Moreover, we specify a viewpoint model for software refactoring, allocate exercises to competence levels and describe an exemplary path for teaching and training.

A fast locking low phase noise 1.6GHz PLL has been presented in this paper. the PLL was designed in 28nm technology with 1V nominal supply voltage. the phase noise of the PLL has been reduced by implementing current starved ring oscillator VCO. the lock time of the PLL is reduced by using a current steering charge pump (CP). the PLL has been designed and simulated in different PVT corners. the simulation results show that the PLL achieves lock state at only 951ns in standard typical PVT (Process, Voltage and Temperature) corner. A low phase noise of only -60.67dBc/Hz at 1MHz has been achieved. It consumes a very low area of only 50u x 45u. the layout of the circuit along with pre and post layout simulation results have been incorporated in this paper.

Translation between natural language and source code can help software development by enabling developers to comprehend, ideate, search, and write computer programs in natural language. Despite growing interest from the industry and the research community, this task is often difficult due to the lack of large standard datasets suitable for training deep neural models, standard noise removal methods, and evaluation benchmarks. this leaves researchers to collect new small-scale datasets, resulting in inconsistencies across published works. In this study, we present CoDesc - a large parallel dataset composed of 4.2 million Java methods and natural language descriptions. With extensive analysis, we identify and remove prevailing noise patterns from the dataset. We demonstrate the proficiency of CoDesc in two complementary tasks for code-description pairs: code summarization and code search. We show that the dataset helps improve code search by up to 22% and achieves the new state-of-the-art in code summarization. Furthermore, we show CoDesc's effectiveness in pre-training-fine-tuning setup, opening possibilities in building pretrained language models for Java. To facilitate future research, we release the dataset, a data processing tool, and a benchmark at https://***/csebuetnlp/CoDesc.

In recent times, there has been an increased demand for alternative energy sources in place of conventional sources for improved environmental conditions, and sustainable way of living. Utilization of daylight for illumination of building interior in place of electricity is a viable means of energy saving. A simple, cost-effective product for daylight exploitation is a solar pipe light. In this context, the design of a solar pipe light is proposed which can redirect natural light without bringing in glare or excessive heat. the design has been constructed and tested in a laboratory. the constructed sample has been implemented at the RIMSO Foundation Battery Manufacturing Factory and its performance has been evaluated at different weather conditions based on Daylight Factor (DF), minimum Daylight Autonomy (DAm), and Useful Daylight Illuminance (UDI). A desirable DF at both laboratory tests and field tests proves the usefulness of the solar pipe light. Considering the results, solar pipe light has great potential to serve the needs for sustainable alternative lighting in the context of Bangladesh.

Despite being regarded as necessary to ensure a system's maintainability and extensibility, software refactoring is often neglected in practice due to difficulties and risks perceived by software developers. Still, refactoring received little attention by software engineering education and training so far. Educational games are a popular means for enhancing practical competences as well as increasing motivation of learners. For instructors, however, it is challenging to develop and apply games in order to address certain learning objectives, which is important to integrate the games into existing or planned training paths. In this article, we propose an ontology that aims to support the analysis and design of games for teaching and training software refactoring. In particular, we create a unifying domain ontology bridging core concepts from three related fields, i.e. game design (a), software refactoring (b), and competence management (c). the resulting ontology is represented as a UML class diagram that reflects concepts and concept relations important for educational refactoring games. We describe ontology-based design options and demonstrate the use of the ontology by analyzing existing games for software refactoring. In addition, we also present an exemplary process for developing novel games based on the ontology and illustrate its applicability by designing a non-digital card game.

the importance of parental involvement (PI) in education is well established. However, the growth of CS Education at K12 level in recent years has raised questions about parents' confidence and competence in engaging in this area withtheir children because of their own lack of CS knowledge and skills. this paper outlines the development and evaluation of family workshops designed to increase parental confidence and competence in partaking of CS activities withtheir primary-school aged children (5-13). A number of design principles were identified through a comprehensive needs analysis leading to the development of a model for family creative-computing workshops. the evaluation aimed primarily to investigate the effect of the strategy on the participants' confidence in partaking in creative computing activities withtheir families. Positive results were found for the sample investigated in whom the mean confidence level rose significantly. Participants reported satisfaction with and enjoyment of the strategy, particularly the inter-family collaboration and the creation of concrete artefacts. Confidence in their ability to organise such activities also rose significantly and a number of the participating families went on to do so. the identification and evaluation of the design principles for family CS activities as well as the workshop model should be of interest to other researchers and practitioners interested in improving PI in CS Education.
