Authors: Kiraki Monicah W. , Murumia Julius G. , Muchiri Francis G.
Published: June 2023

Background: The youth and adolescents constitute a quarter of the sexually active population and they represent almost half of all new STI cases globally. However, there is limited current data on knowledge of safe sex practices among Kenyan university students. This study sought to assess knowledge on safe sex practices among undergraduate students.
Methods: A cross-sectional analytical study design was adopted for this study. A self-administered questionnaire was used to obtain data from undergraduate students. Simple random sampling method was used to sample the participants. Data were analysed using the statistical package of social sciences (SPSS) v.24.
Results: The mean age of the participants was 21.37 (±1.75) years. There were more males (56.5%) than females. Majority of participants (63.1%) came from rural areas and more than three-quarters were Christians (88.6%). Majority were single (83.8%) and most were residing in private hostels (71.9%). The mean knowledge score was 68.15 (±21.59)%. Significant predictors of knowledge level were the place of birth and place of residence; p=0.027, AOR=1.975 and p=0.026, AOR=0.477 respectively.
Conclusions: The findings indicated that the University students had high knowledge of safe sex practices which was associated with their place of birth and residence. There is a need to assess if the high knowledge translates to practice among the students. The institutions of higher learning should continue to teach age-appropriate safe sexual practices to the students such as sexually transmitted infections, contraception and other related topics.

Background: Oral cancer ranks among the top three types of cancer in India. Opportunistic screening of the oral cavity at an early stage could potentially offer long-term survival, improve treatment outcomes, and makes health care affordable for oral cancer patients. The objective is to determine the proportion of suspected oral precancerous lesions among the patients attending the outpatient department of the Primary Health Centres of Puducherry (PHC) by opportunistic screening through visual inspection.
Methods: This study was a facility-based cross-sectional study, conducted at the outpatient department of one urban and one rural primary health centre of Puducherry. Twelve hundred individuals aged above 18 years were opportunistically screened at the outpatient department using systematic random sampling. The oral examination was done through visual inspection, and socio-demographic characteristics were collected using a semi-structured questionnaire.
Results: The prevalence of suspected oral precancerous lesions was 14.3%, of which (18.5%) in rural areas and (10%) in urban areas. The study revealed that 32.1% of the study participants were in 46-60 years with female predominance of 63.3%. A high prevalence of suspected oral precancerous lesions was seen among the age group >60 years (21.8%) and males (19.1%). Smoking, chewing tobacco/betel quid, and alcohol consumption were the risk factors associated with the prevalence of suspected oral precancerous lesions.
Conclusions: Further confirmation of those diagnosed positive for suspected precancerous oral lesions, appropriate follow-up, and treatment of the lesions. Opportunistic screening for all individuals above 30 years of age for suspected oral precancerous lesions is recommended and feasible in primary healthcare settings.

Authors: Ramya Bala Prabha G. , Divya Jyothi Kasa , Pagadala Swathi
Published: June 2023

Pemphigus vulgaris is a rare IgG-mediated autoimmune disease that affects the skin and mucous membranes, causing painful blistering. Pemphigus vulgaris has been reported to be triggered or exacerbated by various factors, including genetic vulnerability, certain drugs, and malignant diseases. We present a case of a patient who was admitted to the dermatology ward with complaints of multiple fluid-filled lesions, initially over the chest, containing clear fluid-filled, ruptured within 1 to 2 hours to leave behind painful raw areas, predominantly over the trunk, scalp, face, upper limbs in the past 2 weeks, and single raw erosions inside the oral cavity after receiving the second dose of Chadox1 nCov-19 coronavirus vaccine (Covishield™), and also mentioned he had developed similar symptoms after the 1st dose of COVID vaccine. We chose to report this case because of the unusual presentation of a rare COVID vaccine adverse drug reaction seen in India.

One health: a long road ahead
Authors: Singh Srishti , Jha S. K.
Published: June 2023

One health (OH) is a collaborative, multisectoral, coordinated and transdisciplinary approach-working at the local, regional, national, and global levels – with the goal of achieving optimal health outcomes by recognizing the interconnection between people, animals, plants, and their shared environment. OH framework was officially recommended as an approach to deal with zoonotic infectious diseases by the world health organization in 2008 of which the core components of the framework are food safety, zoonoses and antibiotic resistance. India has taken some steps towards the OH concept by promoting collaboration among various sectors and allocating the required resources. However, still a lot needs to be done to overcome the challenges. Implementing systematic zoonotic surveillance; regulated antibiotic use among humans and animals; development of a zoonotic registry in the country; constitution of a wide network of academic, research, pharmaceutical and various implementation stakeholders from different sectors is the need of the hour to effectively use OH. Implementing a ' OH ' system consists of emphasizing the intersections of humans, domestic and wild animal populations as well as plants and ecosystems. By promoting collaboration across all sectors, a OH approach can achieve the best health outcomes for people, animals, and plants in a shared environment.

Published: June 2023

Background: Osteoporosis is a very common problem in geriatric population and postmenopausal women. Zoledronic acid injection is a very convenient and effective treatment option available for osteoporosis. Our study aimed to study the effect of zoledronic acid on functional outcome and fracture related complications in elderly patients with low energy pertrochanteric femoral fractures who were operated with proximal femoral nail.
Methods: This was a case control study. Elderly patients who underwent surgery in the form of proximal femoral nailing for low energy pertrochanteric femoral fractures were included. Injection zoledronic acid was given to every alternate patient who underwent surgery. Radiological healing was evaluated at six weekly intervals for six months and then 12 weekly intervals for one year. The Harris hip score was used to measure the functional outcome of the patient.
Results: Effective study population consisted of total 49 patients (25 cases and 24 controls). The mean union time in the cases and the control was 8.76±9.12 weeks and 7.04±1.57 weeks respectively. The mean Harris hip score was 86.742±7.55 in the cases and 84.339±11.20 in the control group. The p value was 0.3815. This study concluded that the two groups had no statistically significant difference between functional outcome and fracture related complications.
Conclusions: Zoledronic acid in patients admitted for surgery with osteoporotic fracture does not improve the functional outcome of the patients. It does not affect the mortality of the patients.

Authors: Gaitán-Lee Hernando , Peña Restrepo Santiago , Suárez Jiménez Luis José , Guzmán Nalus Felipe , Piñeros Rincón Mariana
Published: June 2023

Total femur replacement is a limb salvage surgery indicated for patients with oncological and non-oncological pathologies of the femur. Given the characteristics of the patients, there are essential perioperative considerations such as the previous treatment with chemotherapy or radiotherapy, prevention of thromboembolic events, hemorrhage management, and booking of an intensive care unit. As demanding as the surgical technique is, preventing extensive fibrosis, major bleeding, acetabular defects, and changes in normal anatomy is possible. The complications described include infection, structural failure, tumor progression, aseptic loosening, and soft tissue failure. Functional results and survival vary from series to series, but reports exist as high as 70% at ten years.

Authors: Bhat Ashaq Hussain , Khateeb Erum Waris
Published: June 2023

Anti-glaucoma medications form the first line of treatment in glaucoma management. However, the effectiveness of medical management for glaucoma is dented by poor adherence to anti-glaucoma medications. There is a need to elucidate the barriers to anti-glaucoma adherence and address them in order to increase effectivity of glaucoma therapy. This study is an attempt in estimating anti-glaucoma adherence behavior along with understanding various barriers to adherence.

This cross-sectional, hospital based study was conducted in District Hospital Kupwara, Kashmir division, India over a period of 2 years from June 2020 to June 2022. 303 consecutive patients who were consented were included in this study. Adherence data was collected using self-reporting method in the form of visual analogue scale and 8-item morisky scale.

303 patients having glaucoma were included in this study. Mean age of patients was 53.86 ± 8.04 years ranging from 35–70 yrs. On Visual Analogue Scale, 78 percent were adherent while as 22 percent were non-adherent. As per Morisky Scale, 9 percent showed low adherence, 17 percent had medium adherence and 74 percent were having high adherence. Study patients with poor adherence reported many barriers to adherence especially forgetfulness, cost and side effects.

Non-adherence is a significant problem in medical management of glaucoma seen in almost one-fourth of our patients. Educating patients and their caretakers is a must in preventing glaucoma morbidity and associated economic drain.
Pre-operative minimal-cycloplegia mydriasis for capsulorrhexis in hypermature intumescent cataract
Authors: Roy Parthasarathi , Ganguli Srisha , Tripathi Santanu Kumar
Published: June 2023

Conventionally adrenergic-anticholinergic combination eye drops (e.g., phenylephrine-tropicamide) are used for pre-operative pupillary dilatation in cataract surgery. This achieves synergy in dilatation, but anticholinergic-induced cycloplegia makes already tense lens-capsule of intumescent cataract more taut, and completion of capsulorrhexis becomes difficult, often resulting in Argentanian flag sign, peripheral extension. An alternative mydriasis-without-cycloplegia strategy (phenylephrine) is also tried for better maintenance of mydriasis but it’s capsule-slackening effect was not thought of. Making best of both, we practice a ‘minimal-cycloplegia mydriasis’ approach (MCM) comprising of 0.25% tropicamide and 5% phenylephrine, instilled in succession. This study was planned to compare our MCM regimen with the conventional fixed-dose-combination regimen of 0.8% tropicamide and 5% phenylephrine (Standard).

 To compare the ease and smoothness of capsulorrhexis and relative incidence of complications, in hypermature intumescent cataract surgery, between ocular instillation of alternative ‘MCM’ regimen and the traditional ‘Standard’ regimen.

 The study used a prospective observational 2-arm comparison design. The study commenced with due approval of Institutional Ethics Committee. Sixty-one (61) patients (age range: 42-72yrs, number of Male: Female 19:42) undergoing hypermature intumescent cataract surgery by standard SICS+IOL technique and in whom either of two regimens, MCM or ‘Standard’ were used for papillary dilatation, were observed. Outcome analysis was done by Fisher’s Exact Test.

 Out of a total of 61 cases, 29 received MCM regime and 32 received ‘Standard’ cycloplegic dilator. Difference in dilatation between two groups was statistically non-significant. Frequency of completed rhexis and attainment of post-operative BCVA of 6/12 were higher with MCM regime: p< 0.001 and p< 0.0005 respectively. Anterior chamber reactions on first post-operative day was more frequent with MCM regime (p<0.01), but was transient and cleared totally in a week.

 Minimal-cycloplegia dilatation regime comprising of 0.25% tropicamide and 5% phenylephrine, instilled in succession may be preferred for capsulorrhexis in hypermature intumescent cataract.

Development of Autonomous Artificial Intelligence Systems for Corporate Management
Authors: Romanova Anna
Published: June 2023

The article discusses development of autonomous artificial intelligence systems for corporate management. The function of a corporate director is still one of the few that are legislated for execution by a “natural” rather than an “artificial” person. The main prerequisites for development of systems for full automation of management decisions made at the level of a board of directors are formed in the field of corporate law, machine learning, and compliance with the rules of non-discrimination, transparency, and accountability of decisions made and algorithms applied. The basic methodological approaches in terms of corporate law for the “autonomous director” have already been developed and do not get rejection among representatives of the legal sciences. However, there is an undeniable need for further extensive research in order to amend corporate law to effectively introduce “autonomous directors”. In practice, there are two main options of management decisions automation at the level of top management and a board of directors: digital command centers or automation of separate functions. Artificial intelligence systems will be subject to the same strict requirements for non-discrimination, transparency, and accountability as “natural” directors. At a certain stage, autonomous systems can be an effective tool for countries, regions, and companies with a shortage of human capital, equalizing or providing additional chances for such countries and companies to compete on the global market.

Authors: Ageeva Alina
Published: June 2023

The financial and economic crisis caused by anti-Russian sanctions and geopolitical tensions necessitates an increase in budget expenditures at all levels, in connection with which the issues of improving the fiscal system and reorganizing interbudgetary relations are being updated. To develop plans for adapting to current challenges, achieving the goals of fiscal stability and improving economic performance, transformations in the field of budget processes, the implementation of an effective fiscal policy, and a rethinking of the principles of fiscal federalism are necessary. Achieving this goals predetermines the need to use flexible budget analysis tools, such as agent-based modeling, which allows to reproduce the multi-level structure of the country's economy and budget system, as well as simulate complex budget processes. The article presents an overview of agent-based models developed by foreign and Russian researchers that reproduce various aspects of budgetary processes. The analysis of the architecture of models was carried out and the conceptual ideas of building models in accordance with the types of agents, their behavioral algorithms, as well as the goals of simulation modeling were considered. The expediency and efficiency of using the agent-based approach for modeling complex budgetary processes is substantiated. The analysis carried out in the article allows us to conclude that the agent-based simulation approach is successfully used for the following purposes: testing variable strategies for reforming budgetary processes, predicting the consequences of implementing fiscal policy, choosing the optimal strategy aimed at achieving budgetary self-sufficiency of the regions, as well as creating tools for assessing the effective allocation of budgetary funds to achieve target variables. The results of the study are proposed to be used for agent-based modeling of sanctions effects and search for strategies for reforming the fiscal system in order to counter the financial and economic crisis.

Published: June 2023

O presente trabalho se propõe a destacar os resultados da pesquisa de doutorado “Reflexos da formação docente – uso de tecnologias digitais na prática profissional”, concluída em 2022, no âmbito do programa de Políticas Públicas e Formação Humana (PPFH-UERJ).  A investigação buscou como foco central identificar se cursos de licenciatura – ofertados a distância – formam professores que promovem um uso diferenciado dos recursos tecnológicos na prática profissional em razão da metodologia que optaram estudar. Para além daquilo que aprenderam ao logo da trajetória formativa, objetivou-se perceber o significado da experiência vivida durante o contexto pandêmico, em 2020 e 2021, por meio da expressão dos próprios docentes. Como percurso metodológico, optou-se pela realização de pesquisa descritiva de cunho quantitativo e qualitativo conjugando dois métodos – entrevista semiestruturada (voltada a um grupo micro) e questionário (destinado a um grupo macro). A análise dos resultados evidenciou, entre outros pontos, uma formação – inclusive no período da pandemia - que se dá mais por curiosidade e esforços próprios do educador do que pela experiência vivida no momento de uma formação formal. Entre os principais referenciais teóricos, destacaram-se, ao longo do trabalho, Masetto (2018), Gatti (2016) e Kenski (2016) para tratar a formação docente; e Santos (2019) ao problematizar o contexto da educação e docência online como fenômenos da cibercultura.

Simulating the process of retargeting of optoelectronic Earth observation spacecraft during object shooting
Authors: Kurenkov V. I. , Pupkov E. A. , Kucherov A. S.
Published: June 2023

Design models and algorithms have been developed to estimate the spatial direction of the reorientation of spacecraft for optoelectronic observation of the Earths surface during object shooting, taking into account the relative movement of the surveillance objects in the field of view of the spacecraft. Modeling is simplified due to the choice of such coordinate systems in which the spacecraft is stationary and the surveillance objects move relative to it. The direction of rotation of the spacecraft with a given angular velocity is found at the point of the upcoming intersection of the optical axis of the observation equipment on the Earths surface with the surveillance object moving in the selected coordinate system. The models and algorithms were developed in order to expand the capabilities of Samara Universitys existing software package for evaluating the target indicators and design characteristics of observation spacecraft. Based on the developed re-targeting models, algorithms have been developed for selecting the sequence of shooting observation objects according to the criterion of their maximum number on the orbit of the spacecraft flight and counting the captured objects to assess the performance of survey. An example of the implementation of one of the graphic windows of the software with the developed models and algorithms is given, in which the process of re-targeting the spacecraft is visualized, which is one of the ways to verify the adequacy of the developed models and algorithms.

Authors: Ahmad Nur Izza Nabila , Junaini Syahrul Nizam , Jali Suriati Khartini
Published: June 2023

The application of augmented reality (AR) has been demonstrated, especially in education. However, to our knowledge, no conceptual framework exists to assist in designing effective augmented reality applications for a specific topic in the mathematics curriculum, such as square and square roots. This study proposes a conceptual framework for the design of augmented reality applications for mathematics. Multiple elements were included in the framework, including specification, design, and evaluation. A preliminary study elicited opinions and information from students and teachers. The proposed framework was used as the guideline to develop an augmented reality mobile application for square and square root topics. We later conducted application testing sessions to evaluate the app's usability. The sessions include app demonstration, pre-and post-test, usability testing, and an interview session to assess user satisfaction. Twenty lower secondary students (13 years old; seven males and thirteen females) took part. The findings of the pre-and post-tests and the application's usability and user interface satisfaction test show that the application has been proven effective in learning mathematics. There is a statistically significant difference between the pre-and post-test means. The application effectiveness level is 72.6 percent. Positive responses were also received during the interview. The findings indicate that the suggested framework may serve as a guide for designing future effective augmented reality applications for mathematics learning.

Published: June 2023

Beyond city branding shows the emergence of digital transformation for urban planning, which not only symbolizes the advancement of the use of technology as branding for cities in Indonesia but also as a structured effort to improve the achievement of sustainable development by using technology that is suitable for the growth and development phase of diverse cities in Indonesia. It began with data for development is usually highly dependent on official data from the government. In the digital transformation era, there will be opportunities to provide alternative data by utilizing existing technology to expand citizen communication channels, including social media, which needs to be equipped with requirements to be used as a data source for urban planning. Digital transformation for urban planning should be able to answer the challenges of the context of urban planning in Indonesia with the keywords urban problem, urban growth, planning, and sustainable development, including in choosing the appropriate theme of urban planning of the digital transformation era, which will be highlighted using advance technology. In the case of popular city planning concepts to be adapted like a smart city that tends to be as city branding, it is supposed to be justified, structured, and implemented by considering the planning system, urban governance system, as well as regional autonomy policy in responding to the challenges of urban planning in the era of digital transformation in Indonesia. Here appears the role of soft infrastructure where factors beyond the technical engineering side play an important role, namely human factors, social systems, the competitive side of the private sector, and governance.

Published: June 2023

The goal of this study is to determine the best picture pattern for the tamarind turmeric herb. So far, the taste and color of tamarind turmeric herb have not been consistent, as they are impacted by maturity, and the amount of Turmeric used. The error backpropagation technique, which is commonly used in Content-based image retrieval systems, will be used to recognize image patterns. The main goal is to capture various portions of the tamarind turmeric herb during the extraction procedure. The camera is used to classify the tamarind turmeric herb product, process it into 5x5 pixels, and average the RGB value to obtain stable RGB values in each category, which are then fed into the Error Backpropagation algorithm. The most appropriate and fastest Error Backpropagation algorithm procedure will be found and implemented in a real-time computer. The first way will be to train the algorithm with ten data by changing neurons, layer, momentum, and learning rate, and the second technique will be to test the algorithm with ten data. The results of the training and testing procedure show that the two hidden layers can recognize 100% of inputs, with three input layers for R, G, and B values, ten neurons in the first and second hidden layers, and one output layer with Learning rate 0.5 and Momentum 0.6 as a parameter. Dark yellow is the best image pattern standard for tamarind turmeric herb, with RGB values in the range from 255, 103, 32 to 255, 128, 48.

The 150 kV Koto Panjang â€“ Payakumbuh transmission line has a line length of 86 km with 249 towers, and the occurrence of the back-flashover in their transmission line is 74%, indicated by the high tower footing resistance as that is >3 ohms. The type of rock on the transmission line and the location of the towers, 79% in hilly or mountainous terrains, are among the factors that can cause an increase in the resistance value. The results of this study indicate that the level of back-flashover affects the value of the tower footing resistance by considering the number of electrode installations. When the towers were installed with more electrodes, the value of tower footing resistance, back-flashover level, and insulator voltage could be reduced to less than half of the previous ones. Moreover, the occurrence of the back-flashover rate in each tower can be dropped to â‰¤ 1 back-flashover rate of 100-km/year. Each tower's soil resistivity value has grown, yet fewer back-flashover disruptions exist. The span's length causes this, as the shorter the span, the faster the reflected wave will travel. As a result, it can lower the voltage in the insulator and diminish the likelihood that a flashover would occur.

Consumption of fruit juices product containing various bioactive compounds that are good for health is a current trend. Bignay fruit is a tropical fruit that contains high anthocyanin and can increase its antioxidant ability by adding aloe vera gel (AVG). Bignay fruit also contains organic acids, namely gallic, ferulic, and ellagic acids. AVG is associated with many transparent or colorless polysaccharides and contains functional bioactive chemical compounds. This research aimed to evaluate the effect of AVG concentration on the anthocyanin and antioxidant activity of bignay fruit juice. This research design used a completely randomized design of one factor, namely the concentration of AVG. The formulation of bignay fruit juice with the addition of AVG at concentrations of 25%, 50%, and 75% at a temperature of (6Â±1) Â°C was carried out. The observed variables included total anthocyanins, total flavonoids, vitamin C, antioxidant activity, viscosity, and acidity. All experimental units were repeated three times. Periodic observations of bignay fruit juice were carried out on storage 0, 3, 6, 9, 12, and 15 days. The AVG concentration significantly affected the total anthocyanin, antioxidant activity, and viscosity of bignay fruit juice. The best formula for bignay fruit juice is the addition of AVG with a concentration of 25%. The bignay fruit juice notes a large number of functional compounds until the ninth day of storage. Bignay fruit juice can be a recommendation for health-conscious consumers to fulfill their functional drink desires.

Due to a lack of environmental protection awareness and knowledge, many practices informally recycle smartphone waste to get precious metals. Smartphones are hazardous and toxic waste materials, so they require proper handling not to cause problems for the environment. This study aims to measure the environmental impact and eco-efficiency level of formal recycling practices carried out by licensed companies and compare them with informal recycling practices carried out by the community. Environmental impact measurement uses Life Cycle Assessment with the eco-cost method. The measurement results show informal recycling practices have a higher environmental impact than formal recycling practices. Informal recycling practices harm almost every category, while formal recycling has a significant positive impact on the acidification and metal scarcity categories. Based on the value of the eco-efficiency index, formal recycling practices are affordable and sustainable and have an eco-efficiency level of 100%. Economically, formal recycling provides higher financial benefits than informal recycling. Thus, formal recycling practices are better and more profitable than informal recycling practices from the economic and environmental aspects. So, it is time for Indonesia to switch to a formal recycling process carried out by licensed companies considering the vast potential for waste as a raw material. The government's role is to invite the public to distribute smartphone waste to licensed recycling companies.
Real-Time Bus Arrival Time Estimation API using WebSocket in Microservices Architecture

In almost all countries, public transportation is the primary choice for people to make daily trips. One of the main problems of public transportation is the accuracy of the vehicle arrival schedule information. In some types of public transportation with particular tracks, such as rapid transit (e.g., MRT), the arrival time can be predicted easily because traffic jams do not affect transportation. This is different from buses, which use the same route as other vehicles so that traffic jams could affect them. This study tries to solve this problem by building an API that can be used to get information on the estimated arrival time of the bus. Estimated time is calculated based on the condition of the bus position and the actual condition of highway traffic from Google Directions API. The API was built using microservices technology, so it can be done quickly if it is further developed to a larger scale. The test was conducted on the Trans Jogja Bus by taking two routes, the short and the long routes. Each route could be explored 20 times under varying time and traffic conditions. Then, the difference between the estimated bus arrival time and the actual bus arrival time could be calculated on each trip. Based on the test results, the estimated bus arrival time generated by the API can be said to be entirely accurate because the difference between the estimated time and the actual bus arrival time is less than 30 seconds.

Motivated by an inherent difficulty of foreseeing the exact occurrence of disasters, attempts to rapidly detect and forecast associated information leading towards and in the aftermath of the disaster events can help minimize casualties and collateral damage, particularly in the rural and crowded urban environment. An emerging Internet of Things (IoT) technology is considered promising for these purposes due to Its inherent capability of capturing, sending and processing various types of environmental field data in real-time over a large geographical area. In this paper, the authors introduced MiSREd (Multi-input, Scalable, Reliable, and Easy-to-deploy) as the authorsâ€™ new low cost IoT platform envisioned to meet the needs of an integrated disaster management system. A key part of the MiSREd platform is the incorporation of heterogeneous wireless networks for improvement reliability and availability of message telemetry. Moreover, deployment of low-overhead protocols can improve the network traffic with a lower bandwidth load as a result of data reduction applied to the MQTT protocol. In order to evaluate the effectiveness of MiSREd, an IoT testbed was developed and evaluation was conducted at Western Flood Canal in Semarang, Indonesia. Data transmission testing in the backhaul using the MQTT protocol showed achievement of a transmission delay

One of the problems faced by soccer robots is how to find out the position of the robot itself and other robots on the field. A simple way to find out the robot's position is to use the odometry method. However, odometry is weak in accumulating position errors that reduce the accuracy of the moving robot's absolute position estimation and orientation. This paper presents a robot position data estimation system that is to be implemented on the ERSOW wheeled soccer robot. The robot can determine its position based on a unique landmark: an L-shaped line on the soccer robot field. We use a deep neural network method to recognize landmark L-shaped. Vision systems and deep learning inferences run on the Robot Operating System platform. After obtaining the distance of the robot to the L-shaped landmark, the robot's orientation and position relative to the field can be accurately determined based on the omnidirectional camera's perception. The results of the position estimation system in this study can be used to reduce position errors resulting from the odometry method. Based on the landmark L-shape recognition test results conducted on 641 datasets, the validation accuracy value is 0.806. The results of testing the robot position generated by vision obtained the largest error x about 2.32 cm and y about 1.99 cm.
Variable Precision Multiplier for CNN Accelerators Based on Booth Algorithm

Published: June 2023

As the utilization of CNN increases, many studies on lightweight, such as pruning, quantization, and compression, have been conducted to use CNN models in servers and edge devices. Studies have revealed that quantization greatly reduces the complexity of CNN models while lowering accuracy to a negligible level. CNN models with bit precision lowered from the existing 64/32 floating point to 16, 8, and 4 fixed points are being announced. Therefore, this paper proposes a variable precision multiplier that can select between 16 bits and 8 bits of precision. It consists of four 8-bit booth multipliers. When 16-bit multiplication is selected, the final product is calculated from four partial products, and when 8-bit multiplication is selected, four multiplications are possible simultaneously. The proposed multiplier was designed with Verilog HDL, and its function was verified in ModelSim. And it was synthesized for Altera Cyclone III EP3C16F484C6 using Quartus II 13.1.0 Web Edition. The proposed variable multiplier has increased combinational logic compared to general 8-bit/16-bit booth multipliers, and the clock speed is reduced by 65% and 82%, respectively. However, it can process four 8-bit multiplications within 1.68 times of normal 8-bit multiplication processing time and can process 16-bit multiplication within 75% of the normal 16-bit multiplication processing time. Therefore, the proposed multiplier is expected to increase speed and energy efficiency by selecting bit precision according to the layer in the CNN model.
