Full textAbstract:
Architects are required to have knowledge of current legislation, ergonomics, and the latest technical solutions. In addition, the design process necessitates an appreciation of the quality of the space and a high degree of creativity. However, it is a profession that has undergone significant changes in recent years due to the pressure exerted by the development of information technology. The designs generated by computer algorithms are becoming such a serious part of designers’ work that some are beginning to question whether they are more the work of computers than humans. There are also increasing suggestions that software development will eventually lead to a situation where humans in the profession will become redundant. This review article aims to present the currently used, implemented, and planned computer technologies employed in the design and consider how they affect and will affect the work of architects in the future. It includes opinions of a wide range of experts on the possibility of computer algorithms replacing architects. The ultimate goal of the article is an attempt to answer the question: will computers eliminate the human factor in the design of the future? It also considers the artificial intelligence or communication skills that computer algorithms would require to achieve this goal. The answers to these questions will contribute not only to determining the future of architecture but will also indicate the current condition of the profession. They will also help us to understand the technologies that are making computers capable of increasingly replacing human professions. Despite differing opinions on the possibility of computer algorithms replacing architects, the conclusions indicate that, currently, computers do not have capabilities and skills to achieve this goal. The speed of technological development, especially such technologies as artificial superintelligence, artificial brains, or quantum computers allows us to predict that the replacement of the architect by machines will be unrealistic in coming decades.

Researchers are always looking for the improvement of existing methods. Today, CMOS technology is widely used, which has some advantages and disadvantages. One of the alternative methods for CMOS technology is QCA technology which compared to CMOS, has the advantages of low energy consumption and small occupied area. In this paper, by using the concepts and methods of QCA technology, a digital code converter is presented. In this converter, a new gate is used, which can produce outputs such as 4-input AND, 4-input OR, 4-input NAND, and 4-input NOR. The proposed converter has 10 inputs and 12 outputs. The 10 inputs are decimal numbers from 0 to 9, producing the output equivalent to excess-3, BCD, and gray codes. One of the advantages of this circuit is providing three different codes per input in just one circuit. In addition, due to the use of the new 4-input gate, the occupied area and the number of used cells were minimized. Simulations were performed by using QCADesigner-E version 2.2, and outcomes illustrated that the occupied area is equal to 0.29 μm2 and 380 QCA cells with 7 clock phases are used. The energy dissipation of the presented circuit is 171 meV. Also, given the favorable performance exhibited by the 4-input gate across various measurement parameters, it possesses the capability to be efficiently employed within larger and intricately designed circuits.

Quantum computation draws from theoretical physics, functional analysis, and algorithmic computer science, acting as an interdisciplinary field. The main aim of research in quantum computing is to demonstrate that certain tasks can be completed faster using quantum computers than traditional ones. For this, quantum memory is crucial to developing synchronization tools that coordinate various processes in quantum computers and quantum gates that preserve the identity of quantum states, such as superpositions, and methods to convert preset photons into on-demand photons. Quantum memories are essential for large-scale photonic quantum computing systems, enabling the coherent manipulation, buffering, and retiming of photonic signals. Unlike classical memory, quantum memory allows states to exist in quantum superposition, offering greater flexibility for quantum algorithms than conventional storage systems. While traditional Read-Only Memory (ROM) tends to be slower, quantum computing facilitates the development of novel computer types that operate with qubits as input states, leading to increased storage capacity. This paper proposes a quantum-based ROM (QROM) architecture that utilizes quantum-based binary logic operations and presents an analysis of the systems performance, focusing on heat generation and speed parameters.

Input and output devices are a system that exists on a computer. A computer is a system consisting of various specific components. These components will later be connected to each other and work together, to carry out processes so that they can produce information. In general, the function of a computer is to receive, process and produce data output, various forms of information in the form of text, audio, images or video. The method used in this research is an adapted literature study, and the research flow is described as follows. Figure 1 shows the data collection method used in this research. The purpose of this data collection is to obtain data that will be analyzed and processed so that any existing problems can be found and it is hoped that this research will find solutions to these problems. To collect data, study the literature. This research uses hardware and software to prove the input devices and output devices that are usually used in organizing computers. The characteristics of the I/O system are influenced by the technology of other components, for example the processor. The performance of the I/O system is more complex than the processor. Therefore, increasing CPU time without directly increasing I/O time does not necessarily improve system I/O performance. Computer system performance can be improved by improving hardware and software component technology. In this research, the focus is on I/O device performance, specifically I/O time. This research examines the relationship between CPU time, I/O time, and elapsed time. The results show that increasing CPU time results in increasing I/O time. I/O system performance is very important for computer users. Response time, also known as total elapsed time, is an important performance measure, especially for single-user and personal computers. In commercial computing, high throughput and short response times are required. Behavior, partners, and data rate are three characteristics used to evaluate I/O systems. The performance of a computer system is determined by various factors, including different users, performance measures, and aspects of the system. Performance improvements can be achieved by improving hardware factors that support overall system performance. Performance measurement can be done through response time (execution time) or throughput. Response time aims to minimize the time between starting and completing a task, while higher throughput can be achieved by serving multiple requests simultaneously. Based on research, it can be concluded that the quality of input, process and output in Islamic educational institutions is influenced by various factors. Student input is critical in determining the quality of education, and the institution has implemented a selective process to ensure the admission of motivated and dedicated students. The educational process is characterized by the application of discipline, adherence to schedules, and the instillation of religious values. The institution's output is reflected in the academic achievements of its students, as well as their motivation and participation in various competitions and activities. This research uses a qualitative approach with a case study method, collecting data through documentation and observation. Data analysis was carried out using triangulation and interpreted qualitatively. This study highlights the importance of a holistic approach to education, integrating religious values, community support, and parental involvement to improve the quality of education.

We offer a computer technology for modeling a process of optical imaging with a diffractive imaging lens. The central idea of the technology is to evaluate the quality of the optical system by matching the input and output images against criteria adopted in image processing. For this purpose, same-resolution hyperspectral images are fed to the input and generated at the output. Thanks to the large number of spectral components, a fairly accurate reproduction of the effects associated with the dependence of the refractive index on the wavelength is ensured. To compare input and output images in terms of PSNR (peak signal-to-noise ratio), standard three-component RGB images are "assembled" using standard matching functions over the entire optical range. Results of the study of the dependence of the PSNR indicator on the main parameters of the optical system are given: focal length, linear aperture and the number of diffraction orders taken into account.

The diverse topics included computer models and simulation, biosensors and instrumentation, graphical tracking and computer scheduling, new methods in plant ecology, automation and robotics, Web-based distance diagnostic and recommendation system, GIS and geospatial analysis, and greenhouse environmental control. An individual speaker presented one topic each week with students also visiting some speaker's labs. The students did active, hands on learning through assignments on computer simulations (STELLA simulation language) and graphical tracking (UNH FloraTrack software). They also built, programmed, and ran robots using Lego Mindstorms robotic kits. The course was evaluated using the Univ.'s CAFE system. There were also open-ended questions for student input. On a scale of 1 (strongly disagree) to 5 (strongly agree), mean scores of the 20 CAFE questions ranged from 3.71 to 4.75 with an overall mean of 4.22. When comparisons to other TPSS courses were possible, this course had a higher mean score for four out of seven questions. Course evaluations indicated this special topics course was important and valuable in helping enhance the students' learning experience.

Abstract: With the rise of technology, computing has been embedded in portable electronics like cellphones and palm tops. The QWERTY keyboard is still the primary input method, though. This project proposes a virtual keyboard programme that generates a visual using image processing. This is a representation of a keyboard. When a camera records hand movements as typing inputs, the simulated keyboard will be operational and available. The creation of a virtual cursor that recognizes fingers is based on the same idea. The motions of the hands that move the mouse will be captured by the camera. Use the camera to take a picture of a physical keyboard or mouse so that you may create a virtual version of them.

With the launch of the "Ice Bucket Challenge", ALS, commonly known as amyotrophic lateral sclerosis (ALS), has gradually attracted wider attention in recent years. It is a progressive neurodegenerative disease characterized by the decline of motor neuron function. As the disease progresses, patients often experience symptoms such as muscle atrophy, weakness, and communication difficulties, leading to social isolation and reduced interaction. Based on brain-computer interface (BCI) technology, this project designs an intention recognition automatic output device. By collecting neural activity and converting it into recognizable intention signals, when the user looks at visual stimuli of a specific frequency, the visual cortex will produce steady-state visual evoked potentials (SSVEPs), which will be detected by the electroencephalogram (EEG) system and decoded through artificial intelligence deep learning algorithms. These recognized signals are converted into instructions for automated equipment to accurately control computer operations, allowing patients to use computers for text input and editing, significantly improving the convenience of communication and interaction in patients' daily lives.

For decades, traditional computer interfaces such as keyboards and mouse have been the major way of interaction. These interfaces, however, can be restricted, particularly in situations when hands-free or realistic contact is sought. Gesture-based interactions are made possible by the use of wearable devices such as smartwatches or motion-capture sensors, which allow people to communicate with computers through natural hand and body gestures.Gesture-based Human-Computer Interaction (HCI) is the technique of transmitting orders or input to a computer system using physical gestures such as hand movements, body movements, or facial expressions rather than standard input devices such as keyboards or touchpads. Gestures are a natural and intrinsic means for humans to communicate with one another. When gesture-based HCI is combined with wearable devices, people may interact with computers in a more intuitive and human-like manner. This natural contact improves the user experience and shortens the learning curve for computer systems. Gesture-based HCI is an alternative interaction style that can considerably help those with a physical disability or mobility issues. It allows for hands-free control, making technology more accessible to a wider variety of people, independent of physical ability. Gesture-based interactions have the potential to improve the efficiency of specific jobs, such as presentations, design work, and managing IoT devices. Because users can execute tasks quickly using simple gestures, it can lead to increased productivity and efficiency.

Full textAbstract:
Recent progress in computer technology enables the calculation of lens fields and focal properties on commonly available computers such as IBM ATs. If we add to this the use of graphics, we greatly increase the applicability of design programs for electron lenses. Most programs for field computation are based on the finite element method (FEM). They are written in Fortran 77, so that they are easily transferred from PCs to larger machines.The design process has recently been made significantly more user friendly by adding input programs written in Turbo Pascal, which allows a flexible implementation of computer graphics. The input programs have not only menu driven input and modification of numerical data, but also graphics editing of the data. The input programs create files which are subsequently read by the Fortran programs. From the main menu of our magnetic lens design program, further options are chosen by using function keys or numbers. Some options (lens initialization and setting, fine mesh, current densities, etc.) open other menus where computation parameters can be set or numerical data can be entered with the help of a simple line editor. The "draw lens" option enables graphical editing of the mesh - see fig. I. The geometry of the electron lens is specified in terms of coordinates and indices of a coarse quadrilateral mesh. In this mesh, the fine mesh with smoothly changing step size is calculated by an automeshing procedure. The options shown in fig. 1 allow modification of the number of coarse mesh lines, change of coordinates of mesh points or lines, and specification of lens parts. Interactive and graphical modification of the fine mesh can be called from the fine mesh menu. Finally, the lens computation can be called. Our FEM program allows up to 8000 mesh points on an AT computer. Another menu allows the display of computed results stored in output files and graphical display of axial flux density, flux density in magnetic parts, and the flux lines in magnetic lenses - see fig. 2. A series of several lens excitations with user specified or default magnetization curves can be calculated and displayed in one session.

Wearable Brain-Computer Interfaces (BCIs) signify a critical evolution in human-machine communication, driven by the convergence of neuroscience, engineering, and information technology. With applications that span across industrial, medical, and recreational domains, BCIs hold potential to redefine our interaction with the technological landscape. This manuscript elucidates this transformative juncture, bifurcating into passive and active BCIs. In passive BCIs, innovations leveraging Virtual Reality (VR) and Augmented Reality (AR) are delineated, progress has been demonstrated in the classification of passively induced emotional signals, highlighting the emergence of hands-free control systems like quadcopter control and industrial inspections. The discourse on active BCIs unveils advancements such as real-time handwriting and speech decoding, driver drowsiness detection, and emotion recognition, aided by machine learning techniques. Despite groundbreaking progress, challenges in algorithm optimization, adaptability, multimodal signal complexity, and ethics persist. Future directions emphasize the potential of deep learning and multimode input signals collaboration. The manuscript underscores the societal implications, particularly in rehabilitation, communication, and entertainment. The review, therefore, serves as both an appraisal and a roadmap for the burgeoning field of wearable BCIs, underlining its role as a pathway to enhance human capabilities and quality of life.

Full textAbstract:
Gestures are a natural means of every day human-human communication, and with the advances in gestural input technology, there is an opportunity to investigate gestures as a means of communicating with computers and other devices. The primary benefit of gestural input technology is that it facilitates a touchless interaction, so the ideal market demand for this technology is an environment where touch needs to be minimized. The perfect example of an environment that discourages touch are sterile or clean environments, such as operating rooms (ORs). Healthcare-associated infections are a great burden to the healthcare system, and gestural input technology can decrease the number of surfaces, computers, and other devices that a healthcare provider comes in contact with, thus reducing the likelihood of bacterial contamination. The objective of this research was to map 3D gestural inputs to traditional touchscreen interface designs within the context of anesthesiology. An experimental study was conducted to elicit intuitive gestures from users and assess the cognitive complexity of ten typical functions of anesthesia providers. Intuitive gestures were observed in six out of the ten functions without any cognitive complexity concerns. Two functions, of the remaining four, demonstrated a higher-level gesture mapping with no cognitive complexity concerns. Overall, gestural input technology demonstrated promise for the ten functions of anesthesia providers in the operating room, and future research will continue investigating the application of gestural input technology for anesthesiology in the OR.

Technology improvement related to energy conservation and energy mix low-carbonization is a critical approach for tackling global warming in China. Therefore, we attempt to identify the technology factors of China’s energy consumption change between 2007 and 2012, when China’s economy started slowing. This study proposes a new refined structural decomposition analysis (SDA) based on a hybrid multi-regional input–output (MRIO) model. The technology factors are expressed through the energy input level effect, energy composition effect, and non-energy input effect. We find that the energy level effect was the primary driver for energy reduction, saving 1205 million tonnes of standard coal equivalent (Mtce) of energy, while 520 Mtce was offset by energy composition and non-energy input effects. The sector analysis shows that the energy input level, energy composition, and non-energy input effects of electricity, the chemical industry, and metallurgy are noteworthy. In addition, the sector contribution to energy-use change, by province, related to the three effects, is also studied. From these results, we propose policy suggestions for further energy saving, in order to achieve China’s energy target through technology improvements by the higher priority contributors identified.

Abstract: Human interaction with computers is increasing everyday with the advancement in Technology. The different ways of interaction with computers have become an important factor in choosing devices. Humans are more interested in lightweight, touchless technologies that can make the work easier and easier. In this Paper, a virtual keyboard and mouse that act as touchless input medium to Computers and eliminates the use of physical keyboard and mouse has been proposed. The virtual keyboard and mouse are designed to execute its functionality by recognizing hand gestures. The project is build using Python, OpenCV, MediaPipe technologies which provides features for hand gesture controls. It requires a computer or laptop with camera. The idea is to display the customized keyboard layout on the computer screen and the built-in camera captures the hands and its movements over the virtual keyboard layout. A forefinger hovering over the keyboard keys highlights those keys and when the tips of forefinger and middle finger met, then that key is clicked, which is taken as input to computer and displayed on the screen. A virtual mouse has been designed to function as a physical mouse based on hand gestures. The virtual mouse recognizes the fingertip of forefinger and movement of that finger is considered as cursor movements. When the forefinger points to the elements on the screen, it is highlighted as if the cursor is placed over those elements. The overlapping of tips of forefinger and middle finger are designed as a click.
