Android of Things Based Dual Mode Trolley with Estimation

In the world of today, every supermarkets are employ with shopping trolleys and shopping baskets in order to aid customers to select and store the products which they are purchase. The customers have to drop every product which they purchase into the shopping cart and then proceed to checkout at the billing section. The billing process is quite slow and highly time consuming and has need long queue in the billing counter, and the waiting time considerably high. The concept fit to propose the “Intelligent Shopping trolley” which aims to reduce and possibly eliminate the total waiting time of customers, lower the total manpower requirement and expenses for markets and increase efficiently overall. This system have a two method. They are Automatic mode and Manual mode. In automatic mode the trolley is guide the customer to whole super market. In manual mode the trolley is followed by the customer.

Terminal++ for Robot Researcher Using C#

Purpose: Sometimes our robot researcher needs a terminal program to exchange the data with the robot or automation device. Nevertheless, the readily available terminal program lacks some functionality that is most relevant to the researcher. We feel that a featured rich terminal program can handle lots of communication overhead for the researcher and relieve them from repetitive and time-consuming tasks. In mind for this, we researched and developed a utility program. We added extra features like automatic send, change dynamic data, etc., so our robot researcher can test the system communication better. In this paper, we demonstrated the utility program in detail. It is built using C#, which is under the Microsoft dot net framework. The code is uploaded to GitHub. Anyone can download and use it. It can be customized for their need. All used classes are available in .cs format. Design/Methodology/Approach: This is the software utility program built by the dot net framework of Microsoft visual studio. It has a graphical user interface (GUI) and some object classes. It has a serial and ethernet interface to test the channel. Once the medium is selected, the application will send whatever is written in the input text box. The Data sending may be an automatic or manual process. In manual mode, after typing the command, we need to press the “Enter” key to send the data. In automatic mode, it will send automatically within the preset interval. The transmit and receive content is displayed inside the list box. Findings/results: sometimes, our project goes into a critical phase. We need to have good tools to overcome the situation immediately. This is a helpful tool to trace the communication-related issue. Using this tool, we can observe the outgoing and incoming data traffic. The robot researcher can use it for their communication-related debug purposes.

Six-Month Effectiveness of Advanced vs. Standard Hybrid Closed-Loop System in Children and Adolescents With Type 1 Diabetes Mellitus

IntroductionThe purpose of this study was to assess the effectiveness of advanced- (a-HCL) vs. standard-hybrid closed-loop (s-HCL) systems use up to 6 months of treatment in a real-world setting of children and adolescents with T1DM.MethodsWe retrospectively evaluated all T1DM pediatric users of MiniMed™ 670G system (s-HCL) and 780G system (a-HCL). HbA1c and BMI were collected at baseline and three and six months after HCL start. Data on glycemic control were extracted from reports generated with CareLink™ Personal Software in Manual Mode, at HCL start, after one, three, and six months after HCL beginning.ResultsThe study included 44 individuals with a median age of 13.3 years (range 2- 21 years), 20 on s-HCL, and 24 on a-HCL. a-HCL users had a significantly lower HbA1c compared to s-HCL after six months of HCL use (7.1 vs. 7.7%). Significant differences in HbA1c between a-HCL and s-HCL users were found in children aged 7-14 years (7.1 vs. 7.7% after six months) and in those with a worse (HbA1c >8%) glycemic control at the beginning (7.1 vs. 8.1% after six months). No significant changes in HbA1c were found in a-HCL users that previously used a s-HCL system. Nevertheless, only the use of a-HCL significantly predicted a lower HbA1c after six months. All sensor-specific measures of glycemic control improved from Manual to Auto mode, in both s-HCL and a-HCL, without increasing time spent in hypoglycemia. However, the percentage of individuals with TIR>70% increased significantly in a-HCL users, who attained this target earlier and more stably: younger age, a higher rate of auto-correction, and a lower amount of CHO inserted predicted a TIR>70%. BMI SDS did not significantly change throughout the study period.ConclusionThis real-world study suggests that effectiveness might be greater in a-HCL than in s-HCL, with significant changes in HbA1c, and reaching earlier and more stably the target of TIR >70%, without increasing hypoglycemia or BMI. At the same time, previous users of s-HCL systems did not show any further improvement with a-HCL. Children under the age of 14 years of age, not represented in previous studies, seem to benefit the most from a-HCL pumps as well as individuals with the worst glycemic control.

Numerical Studies of the Dynamics of the Roadheader Equipped with an Automatic Control System during Cutting of Rocks with Different Mechanical Properties

The process of cutting rocks with a boom-type roadheader results in extreme dynamic loads and vibrations. Mining, especially in the case of hard rocks, is associated with large energy consumption, which, when combined with low process efficiency, can lead to low drilling performance. These phenomena are undesirable because excessive dynamic load leads to low machine durability, as well as deterioration of work conditions and safety. Low mining efficiency affects the economics of mining works conducted using roadheaders. However, these adverse effects can be minimized by optimizing the cutting process, thanks to the automatic control of the roadheader. The present article discusses the concept of automatic control of a boom-type roadheader’s cutting heads movement. Based on previously conducted computer investigations, it was assumed that reducing the energy consumption of the cutting process and improving the dynamic state of the roadheader (objective functions) are possible only by controlling three of the four parameters characterizing the cutting process: angular speed of the cutting heads, boom swinging speed, and cut height. The web of cut and workability of the rock can be treated as variables of a stochastic nature. This paper presents selected results of computer tests during simulated cutting of rocks with different uniaxial compressive strengths (UCS) in automatic and manual mode. In addition, the tests studied the behavior of the roadheader during the cutting of rocks with variable workability, which is typical of drilling excavations in a layered rock mass. The results of simulated cutting in automatic and manual mode were compared to assess the effectiveness of the adopted automatic control strategy. It was found that the algorithm developed for automatic control of the cutting heads’ movement allows reducing the consumption of cutting energy by up to half compared to the consumption during cutting in manual mode. Furthermore, it was found to improve the dynamic state of the machine.

Research on Intelligent Position Posture Detection and Control based on Multi-sensor Fusion Method

Aiming at the problems of low efficiency and high safety risks encountered in grabbing and placing the boxes by manual mode, the multi-sensor fusion method of vision and laser ranging sensor is used for position and posture detection, and the global rough positioning is detected by the global binocular camera. Precise positioning uses four local measurement modules, including a monocular camera and three laser ranging modules, to detect the position and posture of the target, and uses Move it in ROS for trajectory planning, obstacle avoidance detection and object grabbing. The intelligent position posture detection and control technology proposed in this paper can effectively improve the timeliness of the box grabbing operation, ensure the safety of the box grabbing operation, and enhance the adaptability to harsh environments.

Ruang daring bercerita: Sebuah narasi tentang rute, navigasi, dan batas dalam arsitektur

Kondisi pandemi yang membatasi pola pergerakan manusia atas ruang, di satu sisi menyebabkan manusia kehilangan makna dan rasa atas kehadiran ruang fisik, tapi di sisi lain memberikan peluang bagaimana cara memaknai ruang dengan cara yang berbeda. Instalasi Kisah Antah-berantah karya Citra Sasmita yang diinisiasi oleh Ruang Seni Anak Komisi UOB Museum MACAN, Jakarta ini berkisah tentang cerita fabel mitologis untuk anak-anak yang diinspirasi dari lukisan kamasan dan karakter cerita rakyat Tantri di Bali. Mempergunakan teknologi web-based augmented reality, Kisah Antah-berantah merupakan perpaduan objek seni dan ruang secara fisik dengan teknologi dunia maya, yang bisa dinikmati secara daring dan luring. Pengamatan karya instalasi Kisah Antah-berantah ini bertujuan untuk memperkaya gagasan atas keterlibatan rute, tur dan bagaimana memaknai batas pada ruang maya. Pengamatan “mengalami ruang” secara daring oleh penulis dijelaskan melalui 2 cara yaitu mode operasi pasif 360˚ dan mode operasi aktif manual. Mode operasi pasif 360˚ menunjukkan bahwa dengan rute yang statis dan terukur, pengalaman memaknai ruang daring bercerita bisa tercapai, meskipun tidak memberikan pemahaman akan batas ruang yang baru. Sebaliknya dengan mode operasi manual aktif, dengan kebebasan rute yang dipilih dan diciptakan sendiri, pengunjung mampu menciptakan batas dan pemaknaan ruang baru yang berbeda. Dari kedua mode operasi ini, tanda (landmark) berupa titik kode optik hadir melampaui objek fisiknya sebagai bagian dari navigasi dalam ruang maya. The pandemic condition that limits human movement over space has consequences that humans lose their meaning and sense of the presence of physical space, otherwise, it provides opportunities to interpret space differently. The installation Kisah Antah-berantah by Citra Sasmita, which was held during a pandemic and initiated by the Ruang Seni Anak Komisi UOB Museum MACAN, Jakarta tells the story of mythological fables for children inspired by kamasan paintings and Tantri folklore characters in Bali, Indonesia. Implementing web-based augmented reality technology, this installation has an equal collaboration of art objects and physical space which can be enjoyed virtually and in a real-time exhibition mode. Kisah Antah-berantah investigates ideas on the involvement of routes, tours, and how to define boundaries in architecture and virtual space. The "experiencing space" will be explained in 2 ways, namely passive 360˚ operation mode and manual active operation mode. The 360˚ passive mode of operation shows that with a static and measurable route, the visitor interprets the virtual space of storytelling completely, although it does not provide a new understanding of spatial boundaries. In manual active of operation mode, visitors potentially create new boundaries and different meanings of space, by creating their routes. In these two modes of operations, an optical code point is presented as a landmark, as an important part of navigation in virtual space.

Third-generation laser balloon ablation: rapid mode applicability is associated with shorter time to pulmonary vein isolation

Background The rapid mode feature implemented in the latest version of the laser balloon system (LB3, HeartLight, X3, Cardiofocus) offers an automated continuous 360° lesion for pulmonary vein isolation (PVI). However, data on its clinical applicability and the potential reduction of procedural times are not yet available. Purpose To explore the use of the rapid mode and its association with PV total and fluoroscopy times in our initial experience with LB3. Methods This analysis included consecutive patients who underwent PVI procedure with LB3. We attempted to perform a complete circular ablation line using the rapid mode at 13 W, but if needed to achieve successful isolation, rapid mode was interrupted and manual mode (5.5–8.5 W) applications were used. The percentage of rapid mode use on the 360° lesion was measured for each PV. Total and fluoroscopy times to complete PVI were also collected. Results A total of 110 PVs were identified in 27 LB3 procedures and successfully isolated with a mean procedural time of 85±31 min. Sixty (55%) PVs were treated by using rapid mode for more than 50% (180°) lesion and 13 (12%) of them had a pure rapid mode ablation (without necessity of manual mode applications). Right inferior PV had the highest use of rapid mode (median value 70%). The main reasons for manual applications were poor PV occlusion, imperfect ostium visualization and presence of blood. PVs with >50% rapid mode use were treated in a significantly shorter time (21.2±13.7 vs 26.8±12.4, p=0.043). Fluoroscopy time did not differ significantly (4.7±4.2 vs 5.4±4.9, p=0.48). Three pinhole balloon ruptures were observed during rapid mode energy application in the second, third and twenty-fifth procedure. No other complications occurred. Conclusions Few PVs could be isolated using pure rapid mode; however, its applicability for more than 50% lesion was observed more frequently and significantly reduced the time to isolation.

Compensation of the error of automotive capacitive fuel level sensors when using them on special self-propelled rolling stock

Consumption of diesel fuel by the special rolling stock of Russian Railways per year amounts to tens of thousands of tons, and the issue of reliable accounting and control of its consumption is quite urgent. Currently, part of the special self-propelled rolling stock is equipped with on-board systems for measuring fuel consumption, however, in many units of this equipment, fuel control and accounting is carried out in manual mode. Massive introduction of on-board fuel consumption measurement systems on special self-propelled rolling stock is constrained, on the one hand, by the rather high cost of fuel sensors used on locomotives, on the other hand, by the increased error of relatively inexpensive automotive capacitive fuel level sensors. As part of the laboratory tests of such sensors, it was determined that when they operate on fuel of the same grade, the error corresponds to the passport and is at the level of 1 %, and when operating on fuel of different grades without additional recalibration, the error can reach 4 % or more. This is largely due to the simplified technology for measuring the amount of fuel in units of volume and insufficient compensation for changes in the density of diesel fuel. To solve this problem, an alternative to standard technology for determining the amount of fuel using automotive capacitive fuel level sensors is proposed, in which the dependence of the readings of these sensors on the fuel density at a standard temperature, once obtained in laboratory conditions, is used. Proposed technology of using automotive capacitive fuel level sensors on a special self-propelled rolling stock will allow keeping its relative reduced error at the level of 1 % and will provide measurement of the amount of fuel in units of mass.

Analysis of the Determinants of Rice and Maize Productivity in the Southern Zone of Senegal

Cereals occupy an important place in the consumption patterns of Senegalese populations. Among these cereals, rice and maize are expected to play a dominant role in the country's food security due to their importance in terms of the area sown. This study examines the determinants of rice and maize productivity in southern Senegal using a Cobb-Douglas production function with cross-sectional survey of 913 family farms. The results show that technical support, the number of plows, and the semi-manual mode have a significant impact on the productivity of both speculations. The technical support and the number of plows lead to an increase in rice and maize production while the manual sowing mode is negatively correlated with this production. Producers should be better equipped and technically supported in order to boost cereal production in Senegal.
