This paper visualizes a salutary approach to maneuver and implement a successful sensor embedded rover that could be used for the surveillance of harmful components like bombs and underground mines that usually contain embedded metallic shrapnel and avoid detonation owning to its light frame. In case of any hostile situation, rescue operations are performed by human and trained dogs in a very precarious pandemonium risking the chances of victimizing themselves. Therefore, to enhance the safety and celerity1 of any defensive op, the rover is controlled directly through bio-electrical signals which are spontaneous in decision making, tweaking their application by using the variations in Electroencephalographic (EEG) and Electrooculographic (EOG) readings in the blink of an eye. Subsequently, the raw mindwave-sensor data is imported into MATLAB, thru the NeuroSky Headset RF receiver, these values are interpreted to normalized ranges so that 4 directions or degrees of freedom shall be implemented, thus opening up possibilities of handsfree-operation. The rover includes Passive-Infrared sensors (PIR) which are used for detecting human presence, motion/mobility and for detecting the illegal entry of intruders across any defensive line. The ATMega 328P microcontroller onboard the Arduino is used to control the sensors on board the while the ZigBee modules are used for ultra-low voltage transmitting and receiving sensor data. Furthermore, an ultrasonic sensor to analyze terrain and measure the distance from impending intrusions vastly improves the rover's mobility on challenging terrains.

ABSTRAKSalah satu faktor yang mempengaruhi daya keluaran listrik dari panel surya adalah posisi dan tingkat penyerapan sinar UV (Ultraviolet) dari matahari. Penggunaan aktuator motor servo untuk solar tracker membebani listrik yang dihasilkan dari pembangkit internal panel surya. Pada penelitian ini dirancang solar tracker menggunakan silinder pneumatik sebagai pengganti aktuator motor servo. Sedangkan, sensor UV digunakan untuk memantau sudut pergerakan matahari. Nilai error dan Δerror dari hasil pengolahan data sensor UV menjadi masukan bagi sistem pengambilan keputusan berbasis kendali fuzzy. Keluaran sistem pengambilan keputusan ini mengatur pergerakan posisi silinder pneumatik naik, turun, atau stop. Pengujian perangkat bekerja dengan baik, menghasilkan respon dinamik overshoot 5,3 % dan error steady state 1,6 %.Kata kunci: ultraviolet, pneumatik, fuzzy, overshoot, errorABSTRACTOne of the factors that affect the electrical output power of solar panels is the position and the absorption level of UV (Ultraviolet) rays from the sun. The use of a servo motor actuator for solar trackers burdens the generated electricity from the solar panels internal generator. In this study, a solar tracker was designed using a pneumatic cylinder as a replacement for the servo motor actuator. While a UV sensor was used to monitor the angle of the sun’s movement. The error and Δerror values from UV sensor data processing results become an input for decision-making systems based on fuzzy control. The output of this decision-making system regulates the movement of the position of the pneumatic cylinder up, down, or stopping. The test device worked properly, resulting in a dynamic response overshoot of 5.3% and a steady-state error of 1.6%.Keywords: ultraviolet, pneumatic, fuzzy, overshoot, error

Expression "Development conditions and perspectives" became important for numerous analyses in various industrial and social areas. Several strategic documents and studies in last two decades analysed projects with topics on perspectives of future development in Serbia. Various tools are used for development of such documents, based on recent scientific and numerical solutions, thus providing reliable assessment for strategic decision making. Almost all analyses tried to implement the theories and practical experiences through the prism of "sustainable development", which included establishment of most important sustainability parameters. Analysis and ranking presented in this paper considered the potential of the Stavalj coal deposit, near city of Sjenica in Serbia, and feasibility of construction project of new mine and thermal power plant. Basis for analysis was a hybrid assessment model which takes into account principles of sustainable development. The model incorporates quantified SWOT analysis, which applies to active underground mines in Serbia. Special attention was given to the parameters describing potential for development.

This article explores four topics raised by Eyal Zamir and Barak Medina's treatment of constrained deontology. First, it examines whether mathematical threshold functions are the proper way to think about limits on deontology, given the discontinuities of our moral judgments and the desired phenomenology of rule-following. Second, it asks whether constrained deontology is appropriate for public as well as private decision-making, taking issue with the book's conclusion that deontological options are inapplicable to public decision-making, whereas deontological constraints are applicable. Third, it examines the issue of the relationship between deontology and efficiency, asking whether deontological constraints should yield in situations where everyone would expect to benefit from their suspension, either ex ante or ex post. Finally, the article concludes that constrained deontology is susceptible to political abuse because of the many degrees of freedom involved in identifying constrained actions and the point at which those constraints yield to consequentialist benefits.

While working on fire ground, firefighters risk their well-being in a state where any incident might cause not only injuries, but also fatality. They may be incapacitated by unpredicted falls due to floor cracks, holes, structure failure, gas explosion, exposure to toxic gases, or being stuck in narrow path, etc. Having acknowledged this need, in this study, we focus on developing an efficient portable system to detect firefighter’s falls, loss of physical performance, and alert high CO level by using a microcontroller carried by a firefighter with data fusion from a 3-DOF (degrees of freedom) accelerometer, 3-DOF gyroscope, 3-DOF magnetometer, barometer, and a MQ7 sensor using our proposed fall detection, loss of physical performance detection, and CO monitoring algorithms. By the combination of five sensors and highly efficient data fusion algorithms to observe the fall event, loss of physical performance, and detect high CO level, we can distinguish among falling, loss of physical performance, and the other on-duty activities (ODAs) such as standing, walking, running, jogging, crawling, climbing up/down stairs, and moving up/down in elevators. Signals from these sensors are sent to the microcontroller to detect fall, loss of physical performance, and alert high CO level. The proposed algorithms can achieve 100% of accuracy, specificity, and sensitivity in our experimental datasets and 97.96%, 100%, and 95.89% in public datasets in distinguishing between falls and ODAs activities, respectively. Furthermore, the proposed algorithm perfectly distinguishes between loss of physical performance and up/down movement in the elevator based on barometric data fusion. If a firefighter is unconscious following the fall or loss of physical performance, an alert message will be sent to their incident commander (IC) via the nRF224L01 module.

In this paper a low power all-digital clock and data recovery (ADCDR) with 1Mhz frequency has been proposed. The proposed circuit is designed for optical receiver circuit on the battery-less photovoltaic IoT (Internet of Things) tags. The conventional RF receiver has been replaced by the visible light optical receiver for battery-less IoT tags. With this proposed ADCDR a low voltage, low power consumption & tiny IoT tags can be fabricated. The proposed circuit achieve the maximum bandwidth of 1MHz, which is compatible with the commercial available LED and light sensor. The proposed circuit has been fabricated in TSMC 0.18um 1P6M standard CMOS process. Experimental results show that the power consumption of the optical receiver is approximately 5.58uW with a supply voltage of 1V and the data rate achieves 1Mbit/s. The lock time of the ADCDR is 0.893ms with 3.31ns RMS jitter period.

Transparency is seen as a panacea for a major problem facing journalism and journalists today, that is, the loss of trust and credibility. However, the scholarly literature has focused primarily on normative considerations, without providing much empirical data that could confirm what are widely assumed to be the positive effects of transparency. In this paper, I argue, first, that editorial texts, in their various manifestations, are the most potent of the various established means of displaying transparency for opening up the production of news item. However, I then draw on my linguistic, process-focused research on quoting and highlight challenges this process creates for the use of editorial texts in the pursuit of transparency. It turns out that conveying the essentials of decision-making that occurs during newswriting requires profound understanding and awareness of the interplay between modalities, co-texts and contexts of language use. Finally, implementing the norm of transparency has allegedly led to the transformation of a well-intentioned goal into an institutional myth, leading journalists – constrained, for example, by the mechanism of impression management – to disclose only socially acceptable practices. Therefore, I conclude by arguing for transdisciplinary research in which scholars research ‘on, for and with’ (Perrin, 2018) other stakeholders in order to bring about a fundamental change in the culture of transparency in journalism.

Decision Theoretic Approach

This paper addresses the fusion processing techniques for multi-sensor data perceived through the infrared sensors of military surveillance robots, and proposes their decision-theoretic coordination to effectively monitor multiple targets. To combine the multi-sensor data from the distributed battlefield robots, a set of fusion rules are used to formulate a combined prediction from the multi-source data. The possible type of a target is estimated through the fusion rules. For the identification of targets, agents need to keep track of targets for continuous situation awareness. The coordination of the agents with limited range of surveillance is indispensable for their successful monitoring of multiple targets. For dynamic and flexible coordination, our agents follow the decision-theoretic approach. We implement a military simulator to compare the capabilities of fusion processing and those of coordination, and conduct experiments with our framework in distributed and uncertain battlefield environments. The experimental results show that the fusion process of multi-sensor data from military robots can improve the performance of estimation of the type of a target, and our coordinated agents outperform agents using random strategy for their target selection in various military scenarios.

This paper presents the performance enhanced humanoid robot LOLA which is currently being manufactured. Hardware design, controllers and simulation are based on ex- perience gained during the development of the robot JOHNNIE. The objective of the current research project is to realize a fast, human-like and autonomous walking motion. To enable an optimal design of the robot with respect to lightweight construction, motor and drive sizing, an appropriate simulation model is required. Dynamics simulation is a key tool to develop the hardware and control design properly. For hardware design and detailed dynamic analysis a comprehensive model including motor and gear dynamics is required, while for controller de- sign and stability analysis a simplified model for global system dynamics is sufficient. Both robots are characterized by a lightweight construction. In comparison to JOHNNIE, the new robot LOLA has a modular, multi-sensory joint design with brushless motors. Moreover, the previously purely central electronics architecture is replaced by a network of decentral joint controllers, sensor data acquisition and filtering units and a central PC. The fusion of motor, gear and sensors into a highly integrated mechatronic joint module has several advantages for the whole system, including high power density, good dynamic performance and reliability. Ad- ditional degrees of freedom are introduced in elbow, waist and toes. Linear actuators are used for the knee joints to achieve a better mass distribution in the legs.
