Reptile Search Algorithm with Deep Convolutional Neural Network for Cloud Assisted Colorectal Cancer Detection and Classification

Cloud-based automatic colorectal cancer (CC) detection involves the usage of cloud computing technology and system to help in the earlier and accurate diagnosis of CC in medical images and patient information. This cloud-based technology aims to improve the efficiency and reliability of CC screening, monitoring, and diagnoses. Automatic CC detection refers to the use of computer-based technology and systems to aid in the earlier and accurate detection of CC in patient data and medical images. This automated system aims to increase the reliability and efficiency of CC monitoring, screening, and diagnosis. Deep learning (DL) methods, especially convolutional neural networks (CNNs), exhibit promising results in automatic CC diagnosis. They can be trained on wide-ranging datasets of medical images to learn patterns and features related to precancerous and cancerous lesion. This study develops a new Reptile Search Algorithm with Deep Learning for Colorectal Cancer Detection and Classification (RSADL-CCDC) technique. The main aim of the RSADL-CCDC method focuses on the automaticclassification and recognition of the CC in the cloud environment. Once the medical images are stored in the cloud server, the detection process is carried out. In the presented RSADL-CCDC approach, the initial stage of preprocessing is performed by bilateral filtering (BF) approach. For feature extraction, the RSADL-CCDC technique applies ShuffleNetv2 model. Besides, the recognition and classification of CC take place using convolutional autoencoder (CAE) model. Finally, the hyperparameter tuning of the CAE technique takes place by utilizing RSA. The experimental validation of the RSADL-CCDC system is performed on benchmark medical database. Extensive results stated the enhanced performance of the RSADL-CCDC technique on CC recognition over other models with respect tovarious actions.

Free Computer-Based Assistive Technology to Support Students With High-Incidence Disabilities in the Writing Process

Written expression is a neglected but critical component of education; yet, the writing process—from prewriting, to writing, and postwriting—is often an area of struggle for students with disabilities. One strategy to assist students with disabilities struggling with the writing process is the use of computer-based technology. This article presents free computer-based technology programs that can be used to support students with disabilities—as well as other struggling writers—in prewriting, writing, and postwriting. While many good for-purchase computer-based writing products exist, this article provides options for teachers and other school personnel trying to balance the needs of students with the realities of school budgets.

A YEAR OF CELEBRATIONS: RAISING CULTURAL AWARENESS IN CLASS

The multinational nature of the English speaking community as well as the increasing use of English by non –native speakers, as it has become the lingua franca of our era, may lead to the assumption that the English language is not tied to any particular culture. This paper however suggests that teachers should choose a pluralistic approach with the ultimate goal of raising their students’ intercultural communicative competence. Thus, it examines both theoretically and practically, through extensive Needs Analyses, and a posteriori students’ evaluations, the appeal of a cultural awareness approach and the success of its implementation by means of a series of organized events. The Needs Analyses prove that the students are eager to learn more about the countries which they overwhelmingly consider a possible destination for studies and/or job (mainly US, UK, Australia, Canada and to a lesser extent Ireland). Celebrations, sports, local cuisines, as well as music and the film industry are absolutely cherished. Their participation in events including British Tea Parties, Irish Saint Patrick’s Day presentations and distinctive American Thanksgiving and Halloween celebrations prove the merit of the cultural awareness approach in EFL. Thus Clarks’s objective “to learn by doing rather than by being taught” can be applied in conjunction with a modern intercultural communicative approach and a strategy of an English language contextualization. Hence, students embark voluntarily on a learning process, improving not only their language but also their research, organizational and communication skills, while achieving cultural familiarization with all English-speaking people. In order to achieve the aforementioned, the use of computer-based technology is a sine qua non since it offers flexibility and redefines the roles of the teacher and the learners as the teacher assumes the role of the facilitator/guide on the side, leading students to autonomy.

Women’s experiences of leisure

To understand issues involved in designing entertainment technology for women, we conducted a preliminary study of the leisure practices of earlier adopting women. Fourteen women kept track of their leisure activities for one week and were interviewed about definitions of leisure, contexts of leisure activities, and the role of technology in their leisure. Four dimensions underlie the participants’ understandings and use of leisure: activities performed alone, versus with others; a primary versus secondary focus; integration versus segmentation; and stimulation versus recuperation. These women rarely used computer-based technologies for leisure. Findings suggest that women might make more use of computer-based technology for leisure if it was designed to fit into existing routines of leisure activity. We propose ways that these findings could inform the design and content of entertainment technologies for women.

AN ELECTRICAL-CIRCUIT MODEL FOR PREDICTING MENTAL WORKLOAD IN COMPUTER-BASED TASKS

ABSTRACT With the increased use of computer-based technology, the work of the human has become more cognitive. As a result, the objective measurement of mental workload has become vital in the design of jobs and the development of adaptive interfaces. This research focused on developing and validating an Ohm's law analogy for mental workload based on individuality and the human's ability to process information. In this model, current was defined as the rate of information transmission (in bit/s); voltage was the mental workload per unit of processed information; resistance was a function of task type and individual factors. To test the hypothesis, the analog voltage-current relationship was evaluated in 24 senior nursing students operating a computer-based system. All subjects performed three different, rule-based, self-paced tasks varying in complexity (low, moderate, and high). Regression analysis across all three tasks showed that a linear relationship existed between the analogs of voltage and current (t (1,69) = −5.97, p = 0.0001), indicating that a negative differential resistance was present. Cognitive ability, fatigue, stress, anxiety, computer skill, and content skill were measured as possible components of resistance. Using stepwise regression analysis, cognitive ability was identified as a significant component of resistance (F(1,22) = 14.2, p = 0.0011). A model relating voltage to current and cognitive ability produced an R 2 = 0.66 for the moderate and high complexity task sets. Similar results were also obtained from a more pragmatic model in which the voltage analog was the mental workload per decision and the current analog was the decision rate (R 2 = 0.63). This electrical-curcuit model could be refined and applied in the workplace for on-line, mental-workload monitoring and in the control of adaptive computer interfaces.

A Web‐based and Group Learning Environment for Introductory Environmental Engineering

AbstractThe use of computer‐based technology is becoming more prevalent in the classroom. As a part of an educational research project sponsored by the GE Foundation, strategies for augmenting a course, Introduction to Environmental Engineering (CE 280), were investigated including cross‐disciplinary experiences in teamwork, design, and the use of advanced teaching technologies such as the web. Interactive tools to assist student learning were developed and refined. Efforts have focused on developing an extensive website, web‐based quizzes and homework assignments, and tutorials. Base groups were used to provide both intellectual and emotional support to students. This paper summarizes the development of this course and the impact of rapid feedback on the progression of student understanding.

Technology as a Tutor, Tool, and Agent for Reading

The use of computer-based technology in teaching reading with students with disabilities is outlined in this article. Research from the last 10 years is presented and discussed using the metaphors of Tutor, Tool, and Agent as categories of instructional purpose. Although the new multimedia technologies now dominate much of the discussion and investigation concerning technology and reading instruction, drill and practice and tutorial computer assisted instructional programs are the most thoroughly researched area of computer use in reading and provide most of the substantive data that is supportive of computer use for students in special education.

Clinical toxicology--past, present and future.

1. The alarming increase in the incidence of self-poisoning in Western countries in the 1950s prompted the establishment of the National Poisons Information Service in the UK and the designation of certain Regional Poisoning Treatment Centres. 2. The substances taken in acute poisoning episodes largely reflect the poisons available in the community and, in the UK at least, have changed with fashions in prescribing although psychotropic drugs and analgesics always predominate. 3. Intensive supportive care with repeat-dose oral activated charcoal and even haemoperfusion has been proved effective in acute poisoning with central nervous depressant drugs such as barbiturates even though these latter drugs are now rarely encountered in overdose. 4. Other advances in clinical toxicology include the introduction of the opiate antagonist naloxone, Fab antibody fragments for life-threatening digoxin overdosage and proven treatment for paracetamol poisoning. Analytical toxicology has also made a major contribution. 5. On the debit side, formal psychiatric assessment of patients after acute poisoning remains contentious, tricyclic antidepressants are still a major problem and there is no effective treatment for poisoning with paraquat or for paracetamol when presentation is delayed. 6. As to the future, although the 'epidemic' of serious acute poisoning of the 1960s and 70s appears to be past its peak, there will always be unusual and serious problems and the UK poisons information services must develop to make the best use of computer-based technology.

An Integrated Approach to Control Analysis and Design

The last few years have seen an increasing trend in the use of computer-based technology for automation and process-control problems. Modern computer-based control systems must be user-friendly, flexible and easily configurable. The use of mass-storage devices with this technology permits the storage of copious quantities of historical plant data. This facility presents the control engineer with an ideal mechanism for performing process-analysis, simulation and control system design. This paper outlines an integrated system which permits an inexperienced user to engineer a computer-based process-control system within a few man days, while at the same time providing the control engineer with access to a set of sophisticated analysis and design tools. The computer system comprises a real-time database, software for communication with front-end input/output equipment, a configurable man-machine interface and a comprehensive logging subsystem for the long-term storage of plant data. A remote access facility allows networking to foreign intelligent devices such as IBM PC's and provides secure access to the real-time database and historical logfiles. Formatted transfer of logfile data to the foreign computers allows the use of proprietary software packages for process study, modelling, system identification and multivariable control system design. This networking facility reduces the necessity for higher level control functions such as optimisation to be implemented in the central process computer.

The Quest For Effective Teaching Methods: Achieving Computer Literacy For End-Users

AbstractComputer literacy has been identified as one of the most important factors for the effective use of computer-based technology at the workplace. Managers need to know about the most efficient methods available to teach computer skills to their workers in a short time and such methods should be suitable for all employees. This paper investigates several approaches used to teach business students about micro-computers. The results show that hands-on teaching is superior to traditional classroom lectures, especially for academically less inclined students. Directions for future research and implications of these findings for management are discussed.

Technology transfer of computer-based applications in law enforcement

As the use of computer-based technology has expanded in law enforcement, one of the central questions is how technology transfer has contributed to this development Drawing on a range of past and current research studies, the paper notes that the expectations of transfer have often exceeded the realities. Factors which both inhibit and enhance technology transfer in law enforcement are therefore outlined, and recommendations for the future are set forth.
