IoT-Based Industrial Debug Message Display Using AWS, ESP8266 And C#

Purpose: In the industrial automation field, debugging is an essential part. Generally, most of the debugging we do in the product development phase and a little bit at the service time. The typical procedure to debug any electronic device is to display a “debug message” inside the terminal window. For this purpose, we commonly use various converters which convert from USB to other ports like RS232, RS485, etc. However, sometimes, we cannot connect our debug cable directly to the working devices. That would be better if the debug message is displayed on the working system terminal without any wire. Here we demonstrate a procedure to display the debug message without any wire. Using the IoT, we do that efficiently. The Code is available on GitHub. Interested researchers can download and continue further research on it. Design/Methodology/Approach: First, We need to create the IoT profile inside the AWS IoT cloud. Using the AWS IoT credential, We update the firmware of the Wifi module. Then it is installed inside the system, which we are debugging. The wifi module’s Transmit and receive pin will be connected to Device’s serial PIN (TX-RX, RX-TX). When the Device sends any debug message through the serial port, it is received by the Wifi module and will update the AWS cloud shadow register. We build an AWS IoT MQTT client in the C# (visual studio. NET). The IoT client fetches the updated data and notifies the UI main thread. One listbox is connected to it. Finally, the UI thread pushes the updated data into the Listbox's first row. Findings/Result: Sometimes, our Device needs to debug without any wire because there is no scope to connect it with the cables. So this procedure can help to debug wirelessly. This procedure has several advantages. Using this debug display eliminates to gets hazards from debugging systems. The debug message can be visible from a remote place. It is also possible to observe the message from multiple remote locations Opening multiple IoT Clients, and subscribing to the same IoT Topic. Originality/Value: The described procedure is a different way to display the debug message. Some advantages are available over traditional procedures. Using this procedure, the researcher can transmit real-time data. It can provide value to the researcher’s work. Using this procedure, the researcher can transmit their sensor data to a remote place. Furthermore, it can save to the remote server for future use. Paper Type: Experimental-based Research.

Vulnerability Evaluation for a Smartphone Digital Twin Workshop under Temporal and Spatial Disruptions

Dynamic performance analysis is essential for production systems facing random disturbances. In this paper, a vulnerability evaluation approach is proposed for smartphone assembly production systems with finite buffers under a resilient system analytic frame. Firstly, four important vulnerability indicators, namely Terminal Time Delay (TTD), Terminal Time Window (TTW), Bottleneck Time Delay (BTD), and Bottleneck Time Window (BTW), are defined to expound temporal and spatial attributes caused by disruptive events. Then, a recursive derivation approach of the queuing network model is presented to obtain a state-transition matrix, wherein machine reliability is also considered in the model. Afterward, the exact solutions of steady and transient vulnerability are evaluated based on state probabilities inference. Finally, numerical studies are carried out to validate the proposed method and translate it into a practical tool. An application program with vulnerability analysis and disturbance control functions is developed, embedded in the digital twin system independently developed by our team to solve practical problems.

Automatic Reading and Billing System of Energy Meter Using IoT

This project describes the implementation of an energy meter with IoT concepts and microcontroller-based designs. The proposed system design eliminates the involvement of human participation in power maintenance. If the purchaser does not pay for the bill within the provided period, power transmission can be switched by the autonomous type of the remote server. The user can control energy consumption in the device from the web page by providing the IP address of the device. The anti-theft recognition unit connected to the energy meter is notified to the company when counter control is performed, and theft recognition information is performed through the modem, and the detected theft is displayed in the terminal window of the company page. The IoT process is carried out by the WiFi unit. The WiFi unit sends data from the energy meter to a web page that can be viewed via an IP address. The hardware interface circuit consists of an ATMEGA 328 microcontroller, MAX232, LCD display, ESP8266 WiFi module and GSM modem. The WiFi unit runs the IOT process by sending data from the energy meter to the website.

Effects of feeding duration, implant dose, and terminal window duration on growth performance and carcass characteristics of feedyard steers and heifers

Our objective was to evaluate effects of feeding duration (days on feed, DOF), terminal window (TW), and implant program dose on growth performance and carcass characteristics of beef steers and heifers. Heifers in Exp. 1 (n = 3,360; 351 ± 31 kg) and Exp. 2 (n = 3,778; 310 ± 28 kg) were used in randomized complete block designs with 3 × 2 factorial treatment arrangements. In Exp. 1, factor 1 was DOF (139, 162, and 183) and factor 2 was TW (60 or 100). In Exp. 2, factor 1 was implant program {(1) IH/H—Component TE-IH with Tylan on d 0 followed by a Component TE-H with Tylan [140 mg of trenbolone acetate (TBA):14 mg of estradiol; Elanco], (2) IH/200—Component TE-IH with Tylan on d 0 followed by a Component TE-200 with Tylan, and (3) 200/200—Component TE-200 with Tylan on d 0 and at reimplant} and factor 2 was TW (60 or 100). In Exp. 3, feedlot data from an industry database (Benchmark, Elanco Knowledge Solutions, Kansas City, KS) was used in an observational study and organized by sex and implant program [steers = IS/200 (total of 280 mg of TBA and 36 mg of estradiol), XS (200 mg of TBA and 40 mg of estradiol), and 200/200 (a total dose of 400 mg of TBA and 40 to 56 mg of estradiol or estradiol benzoate); heifers = IH/200 (total of 280 mg of TBA and 28 mg of estradiol) and 200/200]. Repeated-measure and nonlinear broken-slope models were used to evaluate TW on live performance. In Exp. 1, ADG decreased ( P = 0.03) and final BW, marbling score, hot carcass weight (HCW), backfat thickness, and calculated empty body fat (EBF) increased ( P < 0.03) as DOF increased. In Exp. 2, greater implant program dose tended ( P ≤ 0.10) to increase ADG and DMI and increase ( P ≤ 0.02) G:F, HCW, DP, and LM area. Furthermore, overall dose reduced ( P ≤ 0.03) marbling score and EBF. In Exp. 3, interactions between implant program, live performance, and TW were detected ( P < 0.001). Steers given 200/200 exhibited the greatest ( P < 0.05) ADG, followed by XS and IS/200 from TW 50 to 100. Inversely, steers given XS had the greatest ( P < 0.05) F:G, followed by IS/200 and 200/200 from TW 50 to 90. Heifers administered 200/200 exhibited greater ( P < 0.05) ADG between TW 50 to 70 and reduced ( P < 0.05) F:G through TW 110 compared with IH/200. Increased DOF resulted in reduced ADG and increased HCW and EBF. Increased implant dose improved live performance and HCW. There is a finite number of TW days before growth suffers from inadequate stimuli. Furthermore, cattle type, implant program dose, DOF, and TW all require consideration when designing implant programs.

273 Effect of Feedlot Implant Dose and Terminal Window Timing on Heifer Performance and Carcass Characteristics

Abstract Feedlot heifers (n = 3,778; initial BW = 310 kg; SD = 28 kg) were utilized in a 3 x 2 factorial arrangement (9 pens/treatment) to investigate increasing implant dose and terminal window (TW) timing on growth and carcass merit. Component with Tylan® implant dose treatments were 1. Initial TE-IH [80 mg trenbolone acetate (TBA), 8 mg estradiol (E2)] and terminal TE-H (140 mg TBA, 14 mg E2; IH/H), 2. Initial TE-IH and terminal TE-200 (200 mg TBA, 20 mg E2; IH/200), or 3. Initial TE-200 and terminal TE-200 (200/200). Heifers were fed 171 d with terminal implant administered 100 or 60 d prior to slaughter; initial implant window was inverse (71 or 111 d) to TW. Data were analyzed as a mixed model with block included as a random effect. No significant dose x TW interactions occurred for growth or carcass characteristics (P ≥ 0.06) therefore, main effects are presented. Terminal window treatments resulted in similar (P &amp;gt; 0.25) live performance. Heifers reimplanted 60 d prior to slaughter had improved (P &amp;lt; 0.05) marbling score and lower YG2 carcasses. Final weight, gain, HCW, yield, and LM area increased (linear; P &amp;lt; 0.05), while marbling score and fat thickness decreased (linear; P &amp;lt; 0.05) with increasing heifer implant dose. Heifers implanted with IH/200 had lower (P &amp;lt; 0.05) DMI compared to IH/H. IH/200 and 200/200 had improved (+2.1%; P &amp;lt; 0.05) efficiency compared to IH/H. HCW for 200/200 was +3.2 and 5.5 kg greater than IH/200 and IH/H, respectively. 200/200 were leaner with +7.4% YG 1&amp;2 and -5.4% YG 4&amp;5, but -8.5% Prime &amp; Choice carcass compared to IH/H. Shortening TW from 100 to 60 d prior to slaughter did not alter growth performance. Increased implant dose in heifers improved gain, efficiency, HCW and yield with some quality grade considerations.

A Secure Electronic Messaging System in Client Server Cryptography-RSA Algorithm

The potency and effectiveness of the knowledge systems, in some ways, rely upon its design and the way knowledge area unit transmitted among totally different parties. Similarly, a really crucial side within the computer code development is that the security of knowledge that flows through open communication channels. one in all the foremost widespread design is client/server design that creates the centralization of knowledge storage and process modify, and supply flexibility for applying authentication strategies and coding algorithms inside info systems. whereas the amount of shoppers increase, its need increasing the authentication and coding level as high as potential. Client/server could be a technology that enables to open associate degree interactive session between the user's browser and also the server. during this study, we tend to used client/server design to accomplish secure messaging/chat between shoppers while not the server having the ability to decode the message by applying 2 layer security: one layer of coding between the shoppers and also the server, and also the second layer of coding between the shoppers within the chat space. during this manner, a shopper / Server Cryptography- based mostly Secure electronic messaging System mistreatment RSA (Rivest- Shamir-Adelman), that could be a wide used public-key cryptography and authentication system for encryption of digital electronic messaging transactions like e- mail over the computer network, extranet and net, to write in code and decipher messages in an exceedingly terminal window is developed.

Effects of a single initial and delayed release implant on arrival compared with a non-coated initial implant and a non-coated terminal implant in heifers fed across various days on feed.

Two experiments evaluated the effect of implant number, type, and total steroidal dose on live animal performance and carcass traits in heifers fed for three different days on feed (DOF). In experiment 1, heifers (n = 3,780; 70 heifers/pen and 9 pens/treatment; initial body weight [BW] = 309 kg) were used in a 2 × 3 factorial arrangement of treatments. Factors were as follows: 1) implant (all from Merck Animal Health, De Soto, KS): 200 mg trenbolone acetate (TBA) and 20 mg estradiol-17β (E2) administered on arrival (SINGLE), or 80 mg TBA and 8 mg E2 administered on arrival followed by 200 mg TBA and 20 mg E2 after approximately 90 d (REPEATED) and 2) duration of DOF: harvested after approximately 172, 193, and 214. In experiment 2, heifers (n = 3,719; 65 to 70 heifers/pen and 9 pens/treatment; initial BW = 337 kg) were used with the same factors as experiment 1, except DOF were 150, 171, and 192. No implant × DOF interaction (P ≥ 0.06) was noted for any performance parameters in either experiment. Heifers administered REPEATED had improved (P ≤ 0.05) live gain to feed ratio (G:F) and carcass-adjusted G:F and tended (P = 0.09) to have greater hot carcass weight (HCW) in experiment 1. Increasing DOF resulted in greater (P ≤ 0.01) live and carcass-adjusted final BW and decreased (P = 0.01) live ADG in experiment 1. As DOF increased, HCW, HCW gain, and dressing% (P ≤ 0.01) increased in experiment 1. The mean carcass transfer was 79.6% across the 42 d terminal window in experiment 1. In experiment 2, REPEATED had improved (P = 0.03) carcass-adjusted G:F compared with SINGLE, but HCW was not different (P = 0.36) between treatments. Increased DOF resulted in greater (P ≤ 0.01) final live and carcass-adjusted BW, decreased (P ≤ 0.01) live and carcass-adjusted ADG, and poorer (P ≤ 0.01) live and carcass-adjusted G:F in experiment 2. In experiment 2, dressing percentage was greater (P = 0.02) in REPEATED compared with SINGLE. Heifers given SINGLE had greater (P = 0.01) back fat and estimated empty body fat (EBF), whereas REPEATED had fewer (P = 0.01) Yield Grade 4 carcasses and greater (P = 0.01) longissimus muscle (LM) area. Increased DOF resulted in greater (P ≤ 0.04) HCW, HCW gain, dressing%, back fat, LM area, marbling, EBF%, and United States Department of Agriculture (USDA) Prime-grading carcasses, Yield Grade 4 and 5, and over 454-kg carcasses in experiment 2. Carcass ADG and carcass transfer indicate a 0.70 kg carcass ADG between 150 and 192 DOF, resulting in an average carcass transfer of 72.2% in experiment 2. Although feedlot growth performance and HCW did not differ between the implant regimens tested, increasing DOF resulted in decreased live growth performance while increasing the proportion of USDA prime carcasses and HCW.

ASCIIGenome: a command line genome browser for console terminals.

SummaryCurrent genome browsers are designed to work via graphical user interfaces (GUIs), which, however intuitive, are not amenable to operate within console terminals and therefore are difficult to streamline or integrate in scripts. To circumvent these limitations, ASCIIGenome runs exclusively via command line interface to display genomic data directly in a terminal window. By following the same philosophy of UNIX tools, ASCIIGenome aims to be easily integrated with the command line, including batch processing of data, and therefore enables an effective exploration of the data.ImplementationASCIIGenome is written in Java. Consequently, it is a cross-platform tool and requires minimal or no installation. Some of the common genomic data types are supported and data access on remote ftp servers is possible. Speed and memory footprint are comparable to or better than those of common genome browsers.Availability and ImplementationSoftware and source code (MIT License) are available at https://github.com/dariober/ASCIIGenome with detailed documentation at http://asciigenome.readthedocs.io.Supplementary information Supplementary data are available at Bioinformatics online.

Highly secure data transmission for industrial network using blowfish algorithm in embedded processors

The security system of data transmission is the major aspects of all regions in today situations. Authentication is an important factor for secure transmission through wireless networking. The major problem of wireless data transmission is that the intruders are trying to track the original information or inject the false information. Cryptography technology provides the security system for transmission by using the symmetric key algorithm methods. The proposed system deals with the most secure transmission through wireless network by using the blowfish algorithm which is based on the lower end and higher end processor. The blowfish algorithm performs the action of encoding through ATmega8L processor and the decoding through LPC2148 processor. Lots of security systems were available for data transmission, but the existing system does not have the ability of powerful communications between users. This proposed system of prototype provides an efficient security system is facilitating by the symmetric key algorithm of blowfish algorithm. The encrypted and decrypted data's are displayed on PC via terminal window software. The primary goal of this proposed system is to achieve the major factors namely security, authentication, reliability, system speed and maintenance which are perfectly implemented.

A robust and high precision optimal explicit guidance scheme for solid motor propelled launch vehicles with thrust and drag uncertainty

ABSTRACTA new nonlinear optimal and explicit guidance law is presented in this paper for launch vehicles propelled by solid motors. It can ensure very high terminal precision despite not having the exact knowledge of the thrust–time curve apriori. This was motivated from using it for a carrier launch vehicle in a hypersonic mission, which demands an extremely narrow terminal accuracy window for the launch vehicle for successful initiation of operation of the hypersonic vehicle. The proposed explicit guidance scheme, which computes the optimal guidance command online, ensures the required stringent final conditions with high precision at the injection point. A key feature of the proposed guidance law is an innovative extension of the recently developed model predictive static programming guidance with flexible final time. A penalty function approach is also followed to meet the input and output inequality constraints throughout the vehicle trajectory. In this paper, the guidance law has been successfully validated from nonlinear six degree-of-freedom simulation studies by designing an inner-loop autopilot as well, which enhances confidence of its usefulness significantly. In addition to excellent nominal results, the proposed guidance has been found to have good robustness for perturbed cases as well.

Nanoporous Ru as a carbon- and binder-free cathode for Li-O2 batteries.

Porous carbon-free cathodes are critical to achieve a high discharge capacity and efficient cycling for rechargeable Li-O2 battery. Herein, we present a very simple method to directly grow nanoporous Ru (composed of polycrystalline particles of ∼5 nm) on one side of a current collector of Ni foam via a galvanic replacement reaction. The resulting Ru@Ni can be employed as a carbon- and binder-free cathode for Li-O2 batteries and delivers a specific capacity of 3720 mAh gRu (-1) at a current density of 200 mA gRu (-1) . 100 cycles of continuous discharge and charge are obtained at a very narrow terminal voltage window of 2.75∼3.75 V with a limited capacity of 1000 mAh gRu (-1) . The good performance of the nanoporous Ru@Ni cathode can be mainly attributed to the effective suppression of the by-products related to carbon or binder, the good adhesion of the catalyst to the current collector, and the good permeation of O2 and electrolyte into the active sites of the nanoporous Ru with the open pore system. This new type electrode provides a snapshot toward developing high-performance carbon- and binder-free Li-O2 batteries.

The nose of the sperm whale: overviews of functional design, structural homologies and evolution

The hypertrophic and much elongated epicranial (nasal) complex of sperm whales (Physeter macrocephalus) is a unique device to increase directionality and source levels of echolocation clicks in aquatic environments. The size and shape of the nasal fat bodies as well as the peculiar organization of the air sac system in the nasal sound generator of sperm whales are in favour of this proposed specialized acoustic function. The morphology of the sperm whale nose, including a ‘connecting acoustic window’ in the case and an anterior ‘terminal acoustic window’ at the rostroventral edge of the junk, supports the ‘bent horn hypothesis’ of sound emission. In contrast to the laryngeal mechanism described for dolphins and porpoises, sperm whales may drive the initial pulse generation process with air pressurized by nasal muscles associated with the right nasal passage (right nasal passage muscle, maxillonasolabialis muscle). This can be interpreted as an adaptation to deep-diving and high hydrostatic pressures constraining pneumatic phonation. Comparison of nasal structures in sperm whales and other toothed whales reveals that the existing air sac system as well as the fat bodies and the musculature have the same topographical relations and thus may be homologous in all toothed whales (Odontoceti). This implies that the nasal sound generating system evolved only once during toothed whale evolution and, more specifically, that the unique hypertrophied nasal complex was a main driving force in the evolution of the sperm whale taxon.

Addendum to ``Statistical Software from a Blind Person's Perspective''

This short note explains a solution to a problem for blind users when using the R terminal under Windows Vista or Windows 7, as identified in Godfrey (2013). We note the way the solution was discovered and subsequent confirmatory experiments. As part of his preparations for teaching a blind student in a statistics course, the second author read Godfrey (2013). He also attempted to use the R terminal in conjunction with the screen reading software his student would be using. More important though was his use of the keyboard gestures that a blind person uses in place of mouse clicks; the solution was found quite by accident by not completing the Alt+Tab key combination for switching applications. Godfrey (2013) stated: . . use of R in the terminal window of Windows Vista and Windows 7 has proved problematic for the screen reading software which can 'lose focus'. This means the cursor is no longer able to be controlled by the blind user and the session must be curtailed. This problem is not specific to a particular screen reader, and can be replicated in other terminal windows such as the command prompt of these operating systems. At the time of writing, this problem remains and the author can only recommend using base R in batch mode to compensate. The loss of focus problem still exists, but the blind user can return to having a normal functioning terminal window by a single press of the Alt key alone. The first author has ensured that this solution works for a range of screen reader software, and for both Windows Vista and Windows 7. The R session does not need to be curtailed, meaning that in terms of the options for running an R job, blind users of R under Windows are back on par with their sighted colleagues.

Metal-Organic Framework Synthesis System Based on Fuzzy Predictive Control via Network Transmission

The purpose of this study is to construct metal-organic framework (MOF) synthesis heating systems based on fuzzy method for monitoring and automatic control. In this study, the temperature sensing module for measurements sensed values that it through a wireless ZigBee chips and wired DAQ device for real-time data transmission. Because MOF synthesis, often due to different modes of heating or heating instability caused by its nucleation and crystal growth rate, is an important influence, leading to different crystallinity, the use of fuzzy theory to predict the temperature parameter and instant heating MOF synthesis parameters can be adjusted to improve the accuracy of the system. The research system to RS-232 interface module for infrared emission control packets issued and automated control of the furnace through the infrared receiver module. This study is based on a terminal interface window of Visual Basic programming and LabView graphical diagram for control system design. Finally, this research, through a number of experiments to validate the use of fuzzy system development methods and networks, can improve the accuracy of the reaction efficiency MOF sensing and control the heating system.

In this paper, we proposed SSL VPN-based network access control technology which can verify user authentication and integrity of user terminal. Using this technology, user can carry out a safety test to check security services such as security patch and virus vaccine for user authentication and user terminal, during the VPN-based access to an internal network. Moreover, this system protects a system from external security threats, by detecting malicious codes, based on behavioral patterns from user terminal's window API information, and comparing the similarity of sequential patterns to improve the reliability of detection.

Push Pins, Dots, Customisation, Brands and Services: The Three Waves of Making Digital Maps

This is not the article that I set out to write. The working title for that article was going to be something along the lines of cartography is subjective; my favourite map probably isn’t your favourite map. But every blog post, article or conference talk I write has to start somewhere and armed with this working title I set about trying to find my favourite map. I was spoilt for choice as I had a vast array of sources to choose from. On Flickr there’s the photostream of the Norman B Leventhal Map Center at the Boston Public Library with over 3000 maps to choose from Figure 1. Also on Flickr are all the maps I’ve come across and have favourited. Then there are my tagged social bookmarks on Delicious plus a plethora of mapping and cartography related articles that sit within my browser’s bookmarks. That’s a lot of maps and that’s not even counting those that are offline in my reasonably large collection of map books. I soon found out that reviewing all of these maps was by no means as simple a task as I’d first thought. I’d expected a favourite to leap out of the browser’s window or book’s page at me. Maps were certainly getting my attention but for the wrong reasons. I was able to discount maps I didn’t like or maps I was ambivalent about, but even getting the beginnings of a short list of favourites was proving a thankless task. There were just too many good maps. Time was passing and I wasn’t anywhere near finding a favourite map, let alone writing an article about it. But as I continued browsing maps, I noticed there was something else on my laptop’s screen that was vying for my attention. Actually there were two other things. One was a terminal window that was open and logged into a remote server somewhere on the Internet where I keep a large stash of geographic and mapping data. The other was the icon for the TextMate text editor, sitting in the dock of my Mac, which I use for coding things, usually maps related code. Realisation slowly dawned on me that my favourite map was yet to come into being; it was the next one that I would make, and the one after that and so on. What I would use to make my next map is what this article should be about. Despite working with geographical data for almost 30 years, it was not until 2007 that I made the first map for myself. Now I’m not a cartographer or a professional map-maker; if I had to describe myself as anything I’d term myself as a hybrid of a geotechnologist, in the literal sense of someone who works with geography and technology, and a neogeographer. The combination of geotechnology, of neogeography and more traditional cartographical disciplines has given us repeated phases of acceleration and disruption. In my opinion, today’s uses of digital maps are in the tail end of the second wave of innovation and we’re starting to see the beginnings of a third wave. Each wave overlaps, there’s no clear border or delineation between them, but each wave has distinct characteristics. When talking about making and using digital maps, my focus is on the way in which consumers, developers and the web use resources to create map based experiences, rather than the process of gathering the spatial data that underpins a digital map. The first wave of digital maps was the combination of a variety of factors slowly coming together.
