Abstract:

Chronodisruption deteriorates the health and wellbeing of shift workers. Artificial light at night and the lack of light during the day are major contributors to chronodisruption and need to be optimized in shift work scenarios. Here, we present one solution for a lighting and automation system in an industrial production workplace. The setting is a rapidly rotating shift work environment with morning, evening, and night shifts. We describe a procedure to specify the new lighting through a software-agnostic nonvisual lighting simulation for artificial and daylighting scenarios. Through this process, a new luminaire is created, called Drosa, that allows for a large melanopic stimulus range between 412 and 73 lx melanopic equivalent daylight (D65) illuminance vertically at eye level, while maintaining a neutral white illuminance at task level between 1250 and 900 lx, respectively. This is possible through a combination of glare-free spotlights with adjustable areal wing lights. An individually programmed automation system controls the light dosage and timing during the day and night. The work is relevant for other shift work scenarios, where the presented example and the discussed rationale behind the automation might provide insights. The work is further relevant for other lighting scenarios beyond industrial shift work, as the nonvisual lighting simulation process can be adapted to any context.

Abstract:

The smart home automation system is designed to conveniently manage and monitor household appliances and lighting fixtures remotely, to save time and to use resources effectively. It is a control system for allowing access to home automation devices. The automation devices include lights, fan, camera and doors. It even enhances the main features of the project to control the home appliances from anywhere as remotely. With the camera module, continuous surveillance and protection of the home is accomplished. A significant improvement is achieved in utility costs by an optimal use of energy. Using inexpensive electronic and interactive tools, this initiative can be applied, making it economically, physically and operationally feasible. Basically it involves controlling everything remotely via a visual interface and mobile application. The automation system employs the use of MQTT protocol in order to secure the transmitted device based information to and from in the network. The defense against Man in the Middle attack (MITM) is the main focus of our automation system. The routed messages are checked at the intermediate hub to check for the occurrence of MITM based DoS attacks through manual reset points. .

Abstract:

Background: Specific language impairment (SLI) diagnosis is inconvenient due to manual procedures and hardware cost. Computer-aided SLI diagnosis has been proposed to counter these inconveniences. This study focuses on evaluating the feasibility of computer systems used to diagnose SLI. Methods: The accuracy of Webgazer.js for software-based gaze tracking is tested under different lighting conditions. Predefined time delays of a prototype diagnosis task automation script are contrasted against with manual delays based on human time estimation to understand how automation influences diagnosis accuracy. SLI diagnosis binary classifier was built and tested based on randomised parameters. The obtained results were cross-compared to Singlims_ES.exe for equality. Results: Webgazer.js achieved an average accuracy of 88.755% under global lighting conditions, 61.379% under low lighting conditions and 52.7% under face-focused lighting conditions. The diagnosis task automation script found to execute with actual time delays with a deviation percentage no more than 0.04%, while manually executing time delays based on human time estimation resulted in a deviation percentage of not more than 3.37%. One-tailed test probability value produced by both the newly built classifier and Singlims_ES were observed to be similar up to three decimal places. Conclusion: The results obtained should serve as a foundation for further evaluation of computer tools to help speech language pathologists diagnose SLI.

Abstract:

This paper presents a control system approach for hybrid illumination of administrative offices (225m2) at an university building located at a tropical zone. The main goal was to minimize the energy consumption of artificial lightings (fluorescent), by taking advantage of the high natural lighting level during a workday (8 a.m. and 6 p.m.). The control system devices used for each office are: presence sensor, dimming photocell and dimming ballasts, all them connected to the Andover Infinet Controller. By means of data analysis and daylight curves, energy consumption and financial savings are determined. Subsequently, the average energy consumption per square meter due to the hybrid lighting in the offices (8.5 kWh/m2/year) and typical illumination of the central campus (27 kWh/m2/year) were compared. It was demonstrated that a reduction of energy consumption of about 70%, 50% by daylighting and 20% by automation was obtained.

Abstract:

In this study, experimental studies that the authors have previously performed on a test road for fixed observer conditions to determine the visibility levels are extended to the moving observer position. As a result of the measurements and tests, when the vehicle speed is constant at the current speed limits for urban roads, it has been seen that the visibility level values in the calculation area remain within the acceptable limits and changing the luminous fluxes will not significantly change the visual performance of the drivers up to two lower lighting classes. It has been shown that the light level can be reduced to create two additional classes besides the current one when the traffic density decreases, at the times when vehicle speeds do not decrease. The results are applied as a case study on the Cendere Street. Road lighting classes are determined according to the EN 13201-1 Technical Report. Road lighting classes that can be applied at different times in the Cendere Street change between M3 and M5 according to the average speed of the passing vehicles, traffic density, road and ambient conditions. It is estimated that about 40% energy saving can be achieved when a lighting automation system is installed.

Abstract:

Nowadays, there is an increasing demand for energy saving techniques in residential, industrial, institutional, clinical and other multipurpose indoor and outdoor applications. Lights play an ubiquitous role around the Earth in all types of structures and outdoor surroundings. Hence, the authors propose a universal lighting control device—named Pervasive Adaptive Resourceful Smart Lighting and Alerting Device—accomplished mainly by the use of Arduino UNO R3. The Pervasive Adaptive Resourceful Smart Lighting and Alerting Device works in two modes, namely, light control and alert, by deploying the perceptive light automation and perceptive light automation with buzzer activation algorithms, respectively. The contributions of the paper are: a common lighting control solution for both incandescent and light emitting diode light bulbs for all indoor and outdoor environments. A profound power consumption analysis, and investigation of the proposed device by estimating the Energy Consumption Ratio (ECR) and Relative Energy Saving Ratio (RESR) through the real time deployment in diverse circumstances with 60 W incandescent, 8 W and 0.5 W LED light bulbs is executed. In addition to the evaluation of RESR and ECR characteristics the power consumption of light bulbs in terms of scalable conditions of number of light bulbs is also analyzed. The proposed model is proved to work efficiently for both incandescent and LED light bulbs.

Abstract:

Energy used for lighting is one of the major components of total energy consumption in buildings. Nowadays, buildings have a great potential to reduce their energy consumption, but to achieve this purpose additional efforts are indispensable. In this study, the need for energy savings evaluation before the implementation of lighting control algorithms for a specified building is highlighted. Therefore, experimental tests have been carried out in a university building with laboratories and other rooms, equipped with KNX building automation system. A dimmable control strategy has been investigated, dependent on daylight illuminance. Moreover, a relationship between external and internal daylight illuminance levels has been evaluated as well. Based on the experimental results, the authors proposed a method for the rough estimation of electrical energy savings. Since, according to the EN 15232 standard, Building Automation and Control Systems (BACS) play an important role in buildings’ energy efficiency improvements, the BACS efficiency factors from this standard have been used to verify the experimental results presented in the paper. The potential to reduce energy consumption from lighting in non-residential buildings by 28% for offices and 24% for educational buildings has been confirmed, but its dependence on specific building parameters has been discussed as well.

Abstract:

Historically, Chevron Australia Pty Ltd have utilised Mobile Diesel Lighting Towers (MDLTs), with ‘turtle friendly’ luminaires at the Gorgon natural gas project (located on Barrow Island, Western Australia), operated by Chevron Australia on behalf of a joint venture of the Australian subsidiaries of Chevron (47.3%), ExxonMobil (25%), Shell (25%), Osaka Gas (1.25%), Tokyo Gas (1%) and JERA (0.417%). MDLTs are a known, relatively safe and reliable light source that can be utilised in most locations, though they emit noise, odour, vibrations, waste hydrocarbons and CO2 as well as requiring regular refuelling and general engine maintenance. With recent and significant improvements in solar energy harvest, and battery storage efficiencies, Mobile Solar Lighting Towers (MSLTs) have technical and performance characteristics that are comparable, and in many instances superior, to MDLTs. In addition to these characteristics, Chevron Australia has successfully worked with its Australian supplier, conducting trials on site to introduce a range of additional design and performance improvements. These improvements include simple Human–Machine Interface (HMI) touch screen interface allowing remote automation through WiFi or 4G, real-time battery and performance monitoring, CCTV, geofencing and GPS tracking. The benefits of replacing just 25 owned MDLTs with solar includes the abatement of over 600 tonnes of CO2 and direct operational cost savings of almost A$50 000 per year (not including indirect cost savings or avoided carbon emissions costs). Further, net present value calculations demonstrate a financial benefit exceeding A$1 000 000 over 5 years when the solar towers are leased compared with maintaining existing or purchasing new diesel units. These MSLT units are delivering environmental benefits, direct and indirect financial savings, and reduced health, safety and environment risk, which have been welcomed by the on-site workforce.

Abstract:

Brain computer interfaces are currently considered to greatly enhance assistive technologies and improve the experiences of people with special needs in the workplace. The proposed adaptive control model for smart offices provides a complete prototype that senses an environment’s temperature and lighting and responds to users’ feelings in terms of their comfort and engagement levels. The model comprises the following components: (a) sensors to sense the environment, including temperature and brightness sensors, and a headset that collects electroencephalogram (EEG) signals, which represent workers’ comfort levels; (b) an application that analyzes workers’ feelings regarding their willingness to adjust to a space based on an analysis of collected data and that determines workers’ attention levels and, thus, engagement; and (c) actuators to adjust the temperature and/or lighting. This research implemented independent component analysis to remove eye movement artifacts from the EEG signals and used an engagement index to calculate engagement levels. This research is expected to add value to research on smart city infrastructures and on assistive technologies to increase productivity in smart offices.

Abstract:

In this paper, an intelligent lighting instrumentation and automation system is presented with the objective of achieving high energy-efficiency in greenhouse supplemental lighting based on the Internet of Things (IoT) technology. The system runs on a Raspbian operating system which interacts with wireless-enabled light emitting diode (LED) fixtures for plant growth, an online data server, and different light sensors including RGB and quantum sensors. The communication is achieved through RestFul API, UART, and I2C. The system is utilized to implement a feedback controller that automatically adjusts the light dimming levels and, in particular, the ratio of red and blue light intensities based on the plants’ needs. A series of experiments involving plant growth were conducted which indicate that the proposed system can achieve energy-savings up to 34%, when compared to a conventional time scheduling scheme. Additionally, the experiments demonstrate that the system can achieve a highly uniform light distribution under unpredictable natural lighting conditions while saving energy due to supplemental lighting.

Abstract:

Abstract Task-lighting is a well-known strategy to save energy by bringing light where it is most needed, providing adaptable localised light conditions of special interest in the current home-office context. Despite these benefits and in addition to negatively impacting biological rhythms, the generalization of backlit screens has made task lights less demanded, with screen users tending to accept significantly lower amounts of the illuminance standards. In parallel, the advantages of task-lighting may contradict the energy benefits of presence-driven lighting or blinds automation. This pilot experiment aims at evaluating the task light usage patterns and characteristic preferences for both paper and computer work from a user-centered perspective to provide guidelines in terms of luminaires characteristics. Thirteen participants evaluated three different task lights in both paper and computer conditions. Our results emphasize the role of the luminaire’s form factor, interface and lighting control characteristics, providing general recommendations on luminaire design.

Abstract:

Electrical cost, primarily for lighting, is one of the largest factors inhibiting the development of “warehouse-based” controlled environment agriculture (CEA). In a jointly sponsored collaboration, we have developed a reconfigurable LED lighting array aimed at reducing the electrical energy needed to grow crops in controlled environments. The lighting system uses LED “engines” that can operate at variable power and that emit radiation only at wavelengths with high photosynthetic activity. These light engines are mounted on supports that can be arranged either as individual intracanopy “lightsicles” or in an overhead plane of lights. Heat is removed from the light engines using air flow through the hollow LED strip mounts, allowing the strips to be placed in close proximity to leaves. Different lighting configurations depend on the growth habit of the crops of interest, with intracanopy lighting designed for planophile crops that close their canopy, and close overhead lighting intended for erectophile and rosette crops. Tests have been performed with cowpea, a planophile dry bean crop, growing with intracanopy LED lighting compared to overhead LED lighting. When crops are grown using intracanopy lighting, more biomass is produced, and a higher index of biomass per kW-h is obtained than when overhead LEDs are used. In addition, the oldest leaves on intracanopy-grown plants are retained throughout stand development, while plants lit from overhead drop inner-canopy leaves due to mutual shading after the leaf canopy closes. Research is underway to increase the energy efficiency and automation of this lighting system. This work was supported in part by NASA: NAG5-12686.

Abstract:

Driver behaviour recognition is of paramount importance for in-car automation assistance. It is widely recognized that not only attentional states, but also emotional ones have an impact on the safety of the driving behaviour. This research work proposes an emotion-aware in-car architecture where it is possible to adapt driver’s emotions to the vehicle dynamics, investigating the correlations between negative emotional states and driving performances, and suggesting a system to regulate the driver’s engagement through a unique user experience (e.g. using music, LED lighting) in the car cabin. The relationship between altered emotional states induced through auditory stimuli and vehicle dynamics is investigated in a driving simulator. The results confirm the need for both types of information to improve the robustness of the driver state recognition function and open up the possibility that auditory stimuli can modify driving performance somehow.

Abstract: Digitization of Real Time Systems as Home is an Automation System in which we control the home’s electrical components digitally. In this project we developed an application as a digital platform for controlling system. And the availability of the system will be ensured by the use of Internet. Our System helps users to access their home appliances easily and safely without any change in existing system in their home. So that without changing the actual components of the home, it’s implemented by adding digital interface between user and home. General Home Automation consists of replacement of each component with IoT devices. The availability of the control is limited to small scale area or local control area. Replacement of each component results in increment of investment which is very costly. The connection to the system requires same network to operate. A home automation system controls lighting, temperature, multimedia systems, and appliances. Since these devices and sensors are connected to common infrastructure, they form the Internet of Things. A home automation system links multiple controllable devices to a centralized server. Keywords: Home automation, IoT, Raspberry Pi, Firebase, Electrical Appliances, Android app.

Abstract:

Automated heating, lighting and irrigation systems are nowadays standard features of industrial and commercial buildings, and are also increasingly found in ordinary housing. In addition to the benefits of user comfort, automated technology for buildings saves energy and, above all, it provides enhanced protection against leakage of water and hazardous gases, and against fire hazards. Lightning strikes are a natural phenomenon that poses a significant threat to the safety of buildings. The statistics of the Fire and Rescue Service of the Czech Republic show that buildings are in many cases inadequately protected against lightning strikes, or that systems have been damaged by previous strikes. A subsequent strike can occur within the period between regular inspections, which are normally made at intervals of 2–4 years. Over the whole of Europe, thousands of buildings are subjected to the effects of direct lightning strikes each year. This paper presents ways to carry out wireless monitoring of lightning strikes on buildings and to deal with their impact on lightning conductors. By intervening promptly (disconnecting the power supply, disconnecting the gas supply, sending an engineer to inspect the structure, submitting a report to ARC, etc.) we can prevent many downstream effects of direct lightning strikes on buildings (fires, electric shocks, etc.) This paper introduces a way to enhance contemporary home automation systems for monitoring lightning strikes based on wireless sensor networks technology.

Abstract:

Lamps are electronic devices that produce light turned out to be one of the components in spending considerable electrical costs. The bigger the room, the space will require a lot of lighting to achieve the value of a lighting level according to the Indonesian National Standard (SNI) in the room. The more lamps that are used, the more wasteful the energy is used. Wasteful of energy, so the expenditure for operational costs will be even greater. The role of technology can be used alongside a culture of energy saving. One of them is a light automation system. Automation systems can be realized without programming. based on a survey the place that requires this automation system is a school classroom. Automation systems can be directly coupled with light systems and manual light switches in classrooms, replacing conventional light-on and off-turn systems in classrooms. Its easy installation provides an example for installing an automation system for schools that have a large number of classrooms. The automation sensor used is a type of sensor that has a way of detecting the movement of people in the room. The sensor that can be used the easiest is the Passive Infra Red (PIR) sensor. This sensor itself is the sensor that is most easily available and quite cheap. In realizing the use of this sensor, more than 1 PIR sensor point is required. Sensors that are used more than 1 point will make grouping part of the lighting system in the classroom. If the classroom is not fully used up to the back of the classroom, then it is enough only to turn it on from the front lights to the middle of the classroom. This supports energy saving efforts. Through this automation, it is hoped that there will be a change in the culture of energy saving side by side with technological developments in terms of its use for energy saving.

Pemasangannya yang mudah menjadikan contoh bagi pemasangan sistem otomatisasi bagi sekolah yang memiliki ruang kelas yang cukup banyak. Sensor otomatisasi yang digunakan merupakan jenis sensor yang memiliki cara kerja untuk mendeteksi pergerakan orang di dalam ruangan. Sensor yang dapat digunakan paling mudah yaitu sensor Passive Infra Red (PIR). Sensor PIR merupakan sensor yang paling mudah didapatkan dan cukup murah. Dalam realisasi penggunaan sensor ini diperlukan lebih dari 1 titik sensor PIR. Sensor yang digunakan lebih dari 1 titik akan membuat pengelompokkan bagian dari sistem pencahayaan di ruang kelas tersebut. Jika ruang kelas tidak digunakan sepenuhnya hingga bagian belakang kelas, maka cukup hanya dinyalakan dari lampu bagian depan hingga ruang tengah kelas. Hal ini mendukung upaya hemat energi. Melalui otomatisasi ini diharapkan ada perubahan budaya hemat energi yang berdampingan dengan perkembangan teknologi dalam hal pemanfaatannya untuk hemat energi.

Abstract:

Building automation is concerned with closed- and open-loop control of building services such as heating, cooling, ventilation and air conditioning, lighting and shading. The ultimate goal is to reduce energy consumption while providing comfort for the occupants. However, ensuring human comfort is a complex affair. In case of dissatisfaction, users need to inform the building operators about apparently badly adjusted setpoints. Then, service units of the facility management have to manually analyze how to improve the situation. Due to the complex characteristics of human perception and derived feedback, this can become a troublesome and time-consuming task. This paper describes the main results of our investigations to improve occupant comfort in office buildings using environmental information monitored by a Wireless Sensor Network (WSN) and human perception collected from a feedback tool. A joint information base aligned with static data from building information modeling integrates the information gathered. Reasoning on these data sources allows adjustments of the Building Automation System (BAS) to automatically enhance the tenant’s comfort or suggest necessary adjustments for facility managers. Communication between the different system components is handled via Message Queuing Telemetry Transport (MQTT). A real-world field study shows the potential of the developed approach, proves its feasibility, and demonstrates the functionality of the feedback tool.

Abstract:

Energy consumption by distribution warehouses has become an essential component of green warehousing and research on reducing the carbon footprint of supply chains. Energy consumption in warehousing is a complex and multilayered problem, which is generally considered in the literature in relation to its detailed components, not as part of comparative studies. In this article, the authors consider six cross-sectional variants of warehouse technology, from manual to fully automatic, and analyze the energy consumption of a warehouse in various configurations. A methodology for estimating storage space and determining energy consumption is proposed. The energy balance of the warehouse variants includes energy for material handling equipment operation, energy consumption for building maintenance (heating, cooling, lighting, etc.), and energy generated by the photovoltaic system on the roof. Then, the operational costs of the variants are estimated and, on their basis, an automation index is determined. The index allows for a comparative analysis of energy consumption and the mechanization and automation of a warehouse. It is shown that a significant part of the energy is spent on maintaining a warehouse building, especially in the case of facilities with a low degree of automation.

Abstract:

Understanding the flow of water in natural watercourses has become increasingly important as climate change increases the incidence of extreme rainfall events which cause flooding. Vegetation in rivers and streams reduce water conveyance and natural vegetation plays a critical role in flood events which needs to be understood more fully. A funded project at Loughborough University is therefore examining the influence of vegetation upon water flow, requiring measurement of both the 3-D water surface and flow velocities. Experimental work therefore requires the measurement of water surface morphology and velocity (i.e. speed and direction) in a controlled laboratory environment using a flume but also needs to be adaptable to work in a real river.<br><br> Measuring the 3D topographic characteristics and velocity field of a flowing water surface is difficult and the purpose of this paper is to describe recent experimental work to achieve this. After reviewing past work in this area, the use of close range digital photogrammetry for capturing both the 3D water surface and surface velocity is described. The selected approach uses either two or three synchronised digital SLR cameras in combination with PhotoModeler for data processing, a commercial close range photogrammetric package. One critical aspect is the selection and distribution of appropriate floating marker points, which are critical if automated and appropriate measurement methods are to be used. Two distinct targeting approaches are available: either large and distinct specific floating markers or some fine material capable of providing appropriate texture. Initial work described in this paper uses specific marker points, which also provide the potential measuring surface velocity. The paper demonstrates that a high degree of measurement and marking automation is possible in a flume environment, where lighting influences can be highly controlled. When applied to a real river it is apparent that only lower degrees of automation are practicable. The study has demonstrated that although some automation is possible for point measurement, point matching needs to be manually guided in a natural environment where lighting cannot be controlled.

Abstract:

The recent advent of Internet of Things (IoT), has given rise to a plethora of smart verticals- smart homes being one of them. Smart Home is a classic example of IoT, wherein smart appliances connected via home gateways constitute a local home network to assist people in activities of daily life. Smart Home involves IoT-based automation (such as smart lighting, heating, surveillance etc.), remote monitoring and control of smart appliances. Besides automation, human-in-the-loop is a unique characteristic of Smart home to offer personalized services. Understanding the human behavior requires context processing. Thus, enablement of Smart home involves two prominent technologies IoT and context-aware computing. Further, local devices lying in the smart home have the implicit location and situational information, hence fog computing can offer real-time smart home services. In this paper, the authors propose ICON (IoT-based CONtext-aware) framework for context-aware IoT applications such as smart home, further ICON leverages fog-based IoT middleware to perform context-aware processing.

Abstract:

The objective of this paper is to design an efficient room automation system in POLIMAS to control and automatize lighting, fan and air-condition.. This system will overcome human mistakes where the students or staffs forget to switch off the appliances in classroom or laboratories, and effectively reduce the cost of operation and power consumption of the buildings. Room Automation involves the automation and controlling the electrical appliances. The system will monitors electrical parameters of room appliance such as temperature, humidity and ambient light. The factors like temperature and light can have significant effects on the productivity of office workers as well as students. Thus, classrooms, laboratories and staff offices can be equipped with super sensors featuring temperature and light monitors. Besides, it helps in reducing power consumption by monitoring the environment condition and controlling the appliances as well as conservation of energy in the campus. Furthermore, it provides simple and cost effective to the institution. The system uses Arduino ESP8266 NodeMCU platform as the IoT end-device connecting to various sensors and actuators to the platform via Wi-Fi channel. By using Wi-Fi connectivity, the hardware integrates with software application to control, monitoring and analysis. A sequence testing is conducted to determine the connectivity and integration of hardware and software. The performance of each sensor was performed to measure the accuracy. As a result, PIR sensors are able to detect general movement in effective range of about 10 meters. Moreover, the DHT temperature sensor in range of 5 meters away from air-condition is able to read the present room temperature and send command to the air-condition adjusting the air- condition’s set temperature similar to the air-condition’s remote. Thus, by implementing this system, not only the electrical appliances in a room more manageable and under control but also able to reduce the operational cost and improve environmental protection.

Abstract:

Wireless Sensor Networks are based on the ZigBee standard. ZigBee uses the IEEE 802.15.4 physical and MAC (medium access control) layers to provide standards-based reliable wireless data transfer. Also, ZigBee provides low-power wireless connectivity features. The features allow ZigBee-based products to be installed easily and cost-effectively. Thus, this technology has been attracting extensive research and development efforts to replace the traditional wired solutions for Building Automation Systems. However, wireless communications in indoor building environments are prone to be influenced by multiple concurrent factors, such as multi-path fading, channel contention, other radio interference, human activity and limited battery energy. Also, sensor detection is not fully reliable. Thus, system robustness is very concerning in these applications. In this paper, we propose a reliable wireless sensor network and an accurate occupancy detection mechanism. We implemented this system in an indoor building for the lighting control of public areas, including corridors, a coffee room and a washroom. The system framework was shown to be effective in terms of network communication reliability and sensor detection accuracy.
