• Prototype of a remotely controlled boat to monitor the real-time water characteristics. • Characteristics monitored are temperature, pH, conductivity with GPS location. • Open-source software application and hardware is used for monitoring device. • A low-cost water quality monitoring device. This research work entails the design and manufacturing of a prototype of a remotely controlled boat which can monitor the real-time water characteristic of a large water body like a lake or river. These characteristics can be used to plot a map of a water body and help to identify zones of concentrated contamination. The continuous nature of the water will be identified, and results are shown through a multi-sensor network. It will consider numerous components and presents this ongoing quality through the presentation of its electrical conductivity, pH, total dissolved solids (TDS), along with the temperature of the water that is being tried and tested. The water monitoring and sampling can help in understanding the effect of water pollution on aquatic life. The boat is planned with a square frame structure utilizing PVC pipes which will limit the resistivity of water stream and this shape additionally keeps up the stability of the boat in the water. This water quality observing boat incorporates a Bluetooth module for remote correspondence. All the outcomes are created and shown with their readings on the PC and LED screen, alongside water's pollutants and restriction points. A GPS unit mounted on the boat enables the user to get the exact location of the boat and contamination. The related probe will be immersed in water and reads the data accordingly. The water sampling unit can be used to collect samples at different locations and the samples can be sent for intensive testing. The boat is controlled using a smartphone application for its movement to different locations to conduct the required analysis. The data collected is sent to the data server and displayed with the user-friendly digital display system. The entire system is compact and easy to handle. Thus, this wirelessly controlled boat can prove to be an efficient and accurate water quality monitoring device.

E-Form Standardization Reading Test (SRT) terhadap Kemampuan Membaca Mahasiswa

Many inputs are given by teacher to the students to develop their understanding of reading. Unfortunately, after the learning process has been carried out, many teachers ignore these reading skills tests. In this case, the test is not arranged based on the level of students' reading ability. Therefore, this study aims to create standardized tests, so that each student gets a type of test with the same level of ability even with different teachers. With the latest learning system, the Standardization Reading Test (SRT) will be arranged based on E-form. Students will take the test on their PC or mobile phone screen thereby speeding up the scoring system. This E-form based SRT will take advantage of the Quiz Creator application with features that require students to answer a reading test within a specified time. This research uses a development research type. Researchers developed a standardized test in the Intermediate Reading course. In this study, researchers used the Quiz Maker application. This Standardization Reading Test (SRT) will make it easier to measure students' reading comprehension skills in a valid and efficient manner. The first step is to see the potential and problems possessed by students in Intermediate Reading learning carried out by the chairman and research members. Then, data collection was carried out. Product design and design validation are carried out at a later stage by the chairman and members of the researcher. After being validated by the expert, the researcher revised the design. Product testing is also carried out as a consideration for next steps. If at the time of testing it is not satisfactory, the researcher will revise the design again to obtain the final product, namely the Standardization Reading Test (SRT).

Wireless Dip Temperature Lance for provisioning hot metal analytics of blast furnaces

ABSTRACT Measurement of hot metal temperatures during tapping is a critical operation and is useful in understanding blast furnace thermal conditions. The hot metal temperature is currently determined by dipping a lance into the stream coming out of the taphole. The lance contains a thermocouple. This lance is connected through a very long trailing cable into the local display for the operators. The measuring technique is manual, the operating temperature in the casthouse is very high, and every time the cable has to be moved, this activity becomes unsafe. Therefore, a system is developed to transfer these data wirelessly to the control room. It consists of a low-cost small, battery-powered wireless transmitter, which transmits its readings up to 500 m away to a host receiver. It will fit in with limited changes to the entire current temperature lance. When triggered, it will relay readings at a pre-set time interval continuously to the host receiver. The device monitors and transmits to the host: Thermocouple Input Reading, Connector Ambient Temperature, RF Signal Power, and Battery Condition and will be displayed in real-time on the PC screen. These data are also stored on the cloud platform for various kinds of analytics for optimizing the process.

Factors Influencing Uptake of Prostate Cancer Screening among Adult Males in Iseyin LGA, Oyo State

Background: Prostate cancer (PCa) is the second leading cause of cancer-related death in the world. This study assessed factors influencing uptake of PCa screening at a popular town in Iseyin, Oyo State.Methods: Relevant information was obtained from 376 participants using pre-tested semi-structured questionnaires. Respondents were selected through multistage sampling technique Statistical tests such as Chisquare, Fisher's exact test and Student's T-test were performed to duly analyse data obtained.Results: Participants' mean age was 50.2 + 8.0 years with a larger (58. 5 %) proportion of men aged 50 and below. Overall summarized scores on poor knowledge and negative attitude were 42.8 % and 44.7 % respectively. Specific knowledge regarding location of prostate, risk factors and symptoms was as low as 21.0%, 26.3% and 37.2%, respectively. Barely 27.9 %, 19.9 % and 16.2 % knew prostate specific antigen test, digital rectal examination and ultrasound as PC screening techniques respectively. Previous uptake of screening was very low being 16.0 %. Individuals with poor knowledge and those who are non-professionals are 3 times (Odds Ratio – 0.295) and 2 times (Odds Ratio – 0.524) respectively less likely to do PCa screening compared with their other counterpartsConclusion: The study showed considerable awareness of prostate cancer. However, comprehensive knowledge of its symptoms and the screening methods was greatly lacking. The need is therefore indicated for an aggressive health promotion intervention designed to increase awareness on PCa screening at the community level.

The electro-mechanical control of element NiTi shape memory alloy strip while bending, based on thermal analysis evidence

This paper presents an experimental investigation of a commercial shape memory alloy strip consisting of nickel and titanium (NiTi SMA), which correlates the thermal properties (phase transitions) with the electrical and mechanical properties of the material, allowing to be used for control applications in engineering. The bending performances of the SMA strip at different values of the activation electric current, during heating process, are also investigated. By using the differential scanning calorimetry (DSC) experiments, the thermal characteristics of the SMA strip were identified. The results of this thermal analysis were the basis for determining the equilibrium temperature, entropy and force developed by the SMA strip during the phase transformation. For the study of the SMA strip, the authors have developed an experimental platform, which uses a portable reconfigurable I/O (RIO) device and LabVIEW graphical programming environment for the measurement, testing and rapid control of parameters, and a piezo-film sensor for controlling of SMA strip movement. The real-time measurements and acquired waveforms are displayed on a PC screen, and the data associated with these waveforms are stored for later use, i.e. for applications in safety engineering like the fire extinguishing control, where very short response/activation times are required.

Screening for pancreatic cancer: a review for general clinicians.

Pancreatic cancer (PC) is an exceptionally lethal malignancy with increasing incidence and mortality worldwide. One of the principal challenges in the treatment of PC is that the diagnosis is usually made at a late stage when potentially curative surgical resection is no longer an option. General clinicians including internists and family physicians are well positioned to identify high-risk individuals and refer them to centers with expertise in PC screening and treatment where screening modalities can be employed. Here, we provide an up-to-date review of PC precursor lesions, epidemiology, and risk factors to empower the general clinician to recognize high-risk patients and employ risk reduction strategies. We also review current screening guidelines and modalities and preview progress that is being made to improve screening tests and biomarkers. It is our hope that this review article will empower the general clinician to understand which patients need to be screened for PC, strategies that may be used to reduce PC risk, and which screening modalities are available in order to diminish the lethality of PC.

BRAIN SIGNATURES PERSPECTIVE FOR HIGH-SECURITY AUTHENTICATION

In the recent past, the web (internet) has emerged as the most interactive authentication system for all of us (i.e. Internet banking passwords, system or building access, and e-payment platforms, etc.) and as a result, traditional authentication systems (like passwords or token-based) are never again more secure i.e. they are vulnerable to attacks. As a result, the security of individual information and safe access to a system winds up prime necessities. Therefore, the EEG-based authentication system has recently become a reasonable key for high-level security. This study centers upon P300 evoked potential-based authentication system designing. In this paper, a new visual stimulus paradigm (i.e. [Formula: see text] P300 speller) using pictures of different objects as stimuli for a person authentication system is designed instead of the conventional character-based paradigm (i.e. [Formula: see text] speller) for increasing the classification accuracy and Information Transfer Rate (ITR). The trial begins by exhibiting a collection of pictures of various objects on four corners of the PC screen comprising of random object pictures (non-target) alongside password pictures (target) that trigger P300 reactions. The P300 reaction’s rightness then checks the identity of the subject concerning the focused pictures (Target). The proposed investigation model achieves higher classification accuracy of 96.78%, along with 0.03075 False Rejection Rate (FRR), 0.03297 False Acceptation Rate (FAR), and ITR of [Formula: see text]. This study has shown that P300-based authentication system has an advantage over conventional methods (Password, Token, etc.) as EEG-based systems cannot be mimicked or forged (like Shoulder surfing in case of password) and can still be used for disabled users with a brain in good running condition. The classification results revealed that the performance of the QDA classifier outperformed other classifiers based on accuracy and ITR.

An initial investigation of a wireless patient radiation dosimeter for use in interventional radiology.

Radiation exposure during interventional radiology (IR) procedures is a critical issue. We have developed a wireless real-time dosimeter for IR patients that use nontoxic phosphor (four sensors). We evaluated the basic performance parameters (such as dose linearity, batch uniformity, reproducibility, and wireless-communication conditions) of the developed system using an IR X-ray system. Further, we investigated the influence of noise from other medical equipment on our wireless real-time dosimeter in the IR X-ray room. Overall, our wireless system exhibited excellent performance in terms of uniformity, reproducibility, and linearity; moreover, the wireless communication performance was better. The developed system enabled real-time visualization of patient radiation dose, without noise contamination from other medical equipment. In addition, the wireless system can be easily installed in a location where the PC screen (display) can be readily viewed by the IR physician. Hence, we developed a wireless system that can display the patient radiation dose data in real time; the system performed satisfactorily upon application in radiation dosimetry. Therefore, our wireless system will facilitate the real-time monitoring/management of patient radiation dose during IR.

Extraction of high-frequency SSVEP for BCI control using iterative filtering based empirical mode decomposition

Steady-state visual evoked potential (SSVEP) has been regarded as an efficient way to design a brain computer interface (BCI). Most SSVEP-based BCIs utilize visual stimuli with flashing frequencies lower than 30 Hz, owing to their better signal-to-noise ratio (SNR). However, the practical applications of low-frequency SSVEP-based BCI are limited, because low-frequency SSVEP usually incur uncomfortable visual experience and the risk of photosensitive epilepsy. In contrast, SSVEP-based BCIs using higher stimulation frequencies (>40 Hz) can induce flicker fusion effect for better visualization. In this study, we studied the feasibility of using iterative filtering - empirical mode decomposition (IF-EMD) to implement a BCI cursor system. EEG signals were recorded from dry EEG electrodes with impedance matching circuits. Three stimulation frequencies, designed at 47, 50, and 53 Hz, were chosen to induce high-frequency SSVEPs, in order to control the leftward, forward and rightward movements of the BCI cursor. Ten subjects were recruited, and each subject was requested to complete a control experiment and an application experiment. In the control experiment, subjects were requested to gaze at each flickering target for thirty seconds. In the application experiment, subjects were instructed to move a cursor to reach three targets on a PC screen. The mean accuracy (Acc), command transfer interval (CTI), and information transfer rate (ITR) in the control experiment were 90.7 ± 2.9%, 1.14 ± 0.07 s, and 54.94 ± 5.41 bits/min, respectively. In the application experiment, the mean execution time and CTI were 30.0 ± 4.69 s and 1.50 ± 0.31 s, respectively.

Experimental evaluation of the flexion and extension movement characteristics of toes in a position operation task and a comparison with fingers

Toes are expected to perform various tasks by bending and stretching movements. However, to our knowledge, few studies have examined toe movement for operation. In particular, the characteristics of toe movements when used for operation have not been clarified. To investigate these characteristics, we proposed a new experimental evaluation system using wire displacement sensors. In this system, operators can move a marker shown on a PC screen by toe flexion and extension movements. In the experiment, 16 different operation patterns were considered, and the time required to finish the operation with one or two toes was measured and evaluated based on the average operation time. A comparison between toe flexors and extensors in operation time indicated that toe movements with a large angle were easier than those with a small angle if only one toe was used, but became more difficult if two toes were used. These results suggest that the ease or difficulty of toe movements differed depending on whether one or two toes are used. These results were then compared with those of additional evaluation experiments we conducted using fingers. The results indicated that toe operation requires 3.51 times more time than finger operation if two toes or fingers are used.

Remote Streetlight Monitoring and Controlling System Based on LED and Wireless Sensor Networks

A reasonable methodology towards people in general lighting framework i.e road lights or expressway lights which will be kept turned ON for the entire night in spite of less traffic. This squanders a colossal measure of vitality as there a huge number of open lights to light the roadways. This paper introduces how this wastage can be limited by keeping the light's brilliance to just 30% utilizing propelled sensor innovation and implanted framework which spares normal of 65% of power. This better roadway spares around 116MW of vitality for a year in a 1km stretch interstate along these lines making it all the more encouraging venture to contribute on considering the financial perspective contrasted with other vitality creating ventures. Checking of road lights and controlling is of most extreme significance in creating nation like India to lessen the power utilization. The point of this venture is to build up a framework which is a remote streetlight checking and controlling framework dependent on LED and remote sensor organize. The framework can be set to run in programmed mode, which controls streetlight. This control can make a sensible change as indicated by the occasional variety. Additionally this framework can run in controlled mode. In this mode, we can step up and control streetlights through PC screen terminal. This road light framework additionally incorporates a period cut-out capacity and a programmed control design for much greater power preserving, to be specific when vehicles cruise by, the light will turn on consequently will be turned off .

AR CAPTCHA: Recognizing robot by augmented reality

SummaryWe propose a novel AR CAPTCHA that first uses Augmented Reality to design CAPTCHA. Users should use their cameras on mobile devices to capture a marker in the 3D physical world or PC screens to find the appropriate angle to recognize each 3D character rendered on the marker in a 3D registration manner, which is very hard for machines or robots to do the same thing. Besides, we add many random 2D characters on the marker to make the state‐of‐the‐art scene text recognition methods fail to recognize the target 3D characters. To ensure availability, we design dual‐channel scenario setting (mobile phone and physical world) that enhances the security level of CAPTCHA and single‐channel scenario setting (mobile phone only) that the gyroscope could be used for our CAPTCHA. The experimental results reveal that the recognition accuracy of machines is nearly 0%, while a human could recognize AR CAPTCHA in only a few seconds.

Genetic counselling and personalised risk assessment in the Australian pancreatic cancer screening program

BackgroundPancreatic cancer (PC) is an aggressive disease with a dismal 5-year survival rate. Surveillance of high-risk individuals is hoped to improve survival outcomes by detection of precursor lesions or early-stage malignancy.MethodsSince 2011, a national high-risk cohort recruited through St Vincent’s Hospital, Sydney, has undergone prospective PC screening incorporating annual endoscopic ultrasound, formal genetic counselling and mutation analysis as appropriate. PancPRO, a Bayesian PC risk assessment model, was used to estimate 5-year and lifetime PC risks for familial pancreatic cancer (FPC) participants and this was compared to their perceived chance of pancreatic and other cancers. Genetic counselling guidelines were developed to improve consistency. Follow-up questionnaires were used to assess the role of genetic counselling and testing.ResultsWe describe the Australian PC screening program design and recruitment strategy and the results of the first 102 individuals who have completed at least one-year of follow-up. Seventy-nine participants met the FPC criteria (≥ two first-degree relatives affected), 22 individuals had both a BRCA2 pathogenic variant and a close relative with PC and one had a clinical diagnosis of Peutz-Jeghers syndrome. Participants reported a high perceived chance of developing PC regardless of their genetic testing status. PancPRO reported FPC participants’ mean 5-year and lifetime PC risks as 1.81% (range 0.2–3.2%) and 10.17% (range 2.4–14.4%), respectively. Participants’ perceived PC chance did not correlate with their PancPRO 5-year (r = − 0.17, p = 0.128) and lifetime PC risks (r = 0.19, p = 0.091). Two-thirds felt that current genetic testing would help them, and 91% of tested participants were glad to have undergone genetic testing. Overall, 79% of participants found genetic counselling to be helpful, and 88% reported they would recommend counselling to their relatives.ConclusionsParticipants reported multiple benefits of genetic counselling and testing but continue to seek greater clarification about their individual PC risk. Extension of PancPRO is required to enable personalised PC risk assessment for all high-risk sub-groups. More detailed discussion of PC risk for BRCA2 pathogenic variant carriers, providing a written summary in all cases and a plan for genetics review were identified as areas for improvement.

Monitoring of adequacy/efficacy of pathogenetic therapy in patients with Wilson’s disease by means of computerized testing of hand motor activity

Patients with Wilson’s disease (WD) need lifelong pathogenetic therapy (PGT) to prevent progress of neurodegenerative processes in particular. However, a pharmacological management of copper balance is very diffi cult task because there are the possibility of worsening dramatically of a patient’s neurological status, the potential side eff ects of drugs, inadequacy of the PGT scheme, and the PGT regime violation or refusal of some patients. The necessity of eff ective method for assessment of the adequacy of PGT and monitoring of compliance of patients has led us to create the application Motus Test Set for a Tablet PC with a touch screen. Motus Test Set is aimed for testing of motor actions of the hands, since among the WD neurological manifestations, tremor and hyperkinesis are the most common and sensitive to therapy. Motus Test Set consists of four kinds of tasks (drawing of the cube and tracts in labyrinths, a continuous following a moving object, "piano") which are performed by fi ngers. Hand motor activity was assessed by means of Motus Test Set at the beginning and at the end of hospitalization in 30 WD patients with different PGTs. The usage of the Motus Test Set in most patients (86.67 %) did not cause any problem, as well as did not aff ect their psychosomatic conditions. The computerized testing has defi ned diff erences between patients with various PGT schemes, both on chronometric indices and quality of drawing. The best quality of drawings was demonstrated by patients with Zincteral monotherapy. The patients with the Cuprenyl dose of 1500 to 2250 mg per day and half of the patients with PGT regime violation had the worst drawing. In patients after a lowering dosage/replacement of Cuprenyl, the time of contact with the screen increased, the drawing time of the cube was reduced by almost 60 %, the quali ty of graphic images improved signifi cantly. In patients, who returned to PGT, the time of contact with the PC screen in labyrinths tasks signifi cantly increas, the quality of the tracts drawn was improved, the algorithm of a cube drawing was restored. Therefore, the Motus Test Set is a useful tool to assess the PGT adequacy / effi cacy and the compliance of WD patients.

SmartEmoDetect: An Internet of Things Based Emotion Monitoring Wearable Technology for Drivers

Negative emotional reactions are the major source of severe accidents on the road. In this paper, an IoT based wearable device is proposed that will estimate the four negative emotions (stress, anger, terror, sad) in the driver and hence would be helpful to prevent roadway disasters. An intelligent stress monitoring control system at the cloud to analyze the sensor signals and to make the decision based upon the variation received in the signals is proposed. This system can also be effective for the government bus drivers. An auditory output response is from buzzer and a warning message is displayed on the screen inside the vehicle. The continuously monitored real time sensor data in the form of graphs is displayed on the PC screen considered as a central server. When any of the sensor value exceeds predefined threshold value, the driver is considered to be in subconscious state and the break system will be implemented to stop the DC motor.

Altered syntactic abilities in first episode patients: An inner phenomenon characterizing psychosis

BackgroundResearch has consistently shown that language abilities represent a core dimension of psychosis; however, to date, very little is known about syntactic comprehension performance in the early stages of psychosis. This study aims to compare the linguistic abilities involved in syntactic comprehension in a large group of First Episode Psychosis (FEP) patients and healthy controls (HCs). MethodsA multiple choice test of comprehension of syntax was administered to 218 FEP patients (166 non-affective FEP patients [FEP-NA] and 52 affective FEP patients [FEP-A]) and 106 HCs. All participants were asked to match a sentence they listen with one out of four vignettes on a pc screen. Only one vignette represents the stimulus target, while the others are grammatical or non-grammatical (visual) distractors. Both grammatical and non-grammatical errors and performance in different syntactic constructions were considered. ResultsFEP committed greater number of errors in the majority of TCGB language domains compared to HCs. Moreover, FEP-NA patients committed significantly more non-grammatical (z = −3.2, p = 0.007), locative (z = −4.7, p < 0.001), passive-negative (z = −3.2, p = 0.02), and relative (z = −4.6, p < 0.001) errors compared to HCs as well as more passive-affirmative errors compared to both HCs (z = −4.3, p < 0.001) and FEP-A (z = 3.1, p = 0.04). Finally, we also found that both FEP-NA and FEP-A committed more grammatical (FEP-NA: z = −9.2, p < 0.001 and FEP-A: z = −4.4, p < 0.001), total (FEP-NA: z = −8.2, p < 0.001 and FEP-A: z = 3.9, p = 0.002), and active-negative (FEP-NA: z = −5.8, p < 0.001 and FEP-A: z = −3.5, p = 0.01) errors compared to HCs. ConclusionsThis study shows that the access to syntactic structures is already impaired in FEP patients, especially in those with FEP-NA, ultimately suggesting that language impairments represent a core and inner feature of psychosis even at early stages.

Consumer Acceptability, Eye Fixation, and Physiological Responses: A Study of Novel and Familiar Chocolate Packaging Designs Using Eye-Tracking Devices.

Eye fixations on packaging elements are not necessarily correlated to consumer attention or positive emotions towards those elements. This study aimed to assess links between the emotional responses of consumers and the eye fixations on areas of interest (AOI) of different chocolate packaging designs using eye trackers. Sixty participants were exposed to six novel and six familiar (commercial) chocolate packaging concepts on tablet PC screens. Analysis of variance (ANOVA) and multivariate analysis were performed on eye tracking, facial expressions, and self-reported responses. The results showed that there were significant positive correlations between liking and familiarity in commercially available concepts (r = 0.88), whereas, with novel concepts, there were no significant correlations. Overall, the total number of fixations on the familiar packaging was positively correlated (r = 0.78) with positive emotions elicited in people using the FaceReader™ (Happy), while they were not correlated with any emotion for the novel packaging. Fixations on a specific AOI were not linked to positive emotions, since, in some cases, they were related to negative emotions elicited in people or not even associated with any emotion. These findings can be used by package designers to better understand the link between the emotional responses of consumers and their eye fixation patterns for specific AOI.

Analysis of EEG Frequency Components and an Examination of Electrodes Localization during Speech Imagery.

This paper reports a result of analysis of EEG frequency components and an examination of electrodes localization for relating the intention ("I want to drink") to "with/without speech imagery" when drink images are displayed on the PC screen. An experimental process was set in 8 sec as followings; fixation image display (1 sec), drink image display (2.5 sec), intention check (1.5 sec), fixation image display (1 sec), and speech imagery period (2 sec). It was repeated 100 times. EEG was measured with 10-20 system in a magnetically-shielded room with BPF (0.08-100Hz) and notch-filter (50Hz) for 10 participants. In the analysis, it was averaged with 35 trials dividing between "with/without speech imagery" in an epoch (fixation image display and speech-imagery) of 2.9 sec. Event-related synchronization (ERS) and desynchronization (ERD) were examined with event-related spectral perturbation (ERSP) and t-test. ERS were observed in α band on the left-hemisphere in case of "with speech imagery" for latency of 500-1500 ms and the significant differences (p<; 0.05) were shown in the left-hemisphere and occipital-region. It is suggested the useful information of selecting electrode positions to detect EEG frequency components for judgment of "with/without speech imagery" in the intention. From these results, we examined the electrodes localization in the with/without speech imagery identification.

An Examination of EEG Frequency Components Related to Speech Imagery and Its Identification

This study is to examine EEG frequency components relating the intention (“I want to drink”) to “with/without speech imagery” when drink-images are displayed on the PC screen. An experimental process was set in 8 s as followings; fixation image display (1 s), drink image display (2.5 s), intention check (1.5 s), fixation image display (1 s), and speech imagery period (2 s). It was repeated 100 times. EEG was measured with 10-20 system in a magnetically shielded room with BPF (0.08-100 Hz) and notch filter (50 Hz) for 10 subjects. In the analysis, it was averaged with 35 trials dividing between “with/without speech imagery” in an epoch (fixation image display and speech imagery) of 3 s and time-frequency analysis was done. Event-related synchronization (ERS) and desynchronization (ERD) were examined with t-test. ERS were observed in α-band on the left-hemisphere in case of “with speech imagery” for latency of 500-1500 ms and the significant differences (p<0.05) were shown in the left-hemisphere and occipital-region. It is suggested the useful information of selecting electrode positions to detect EEG frequency components for judgment of “with/without speech imagery” in the intention. In addition, an examination to localize electrode was conducted. As a result, it is suggested that averaged RMS value for each frequency component gives useful information even when localized to 9 electrodes.
