Advanced Line-of-Sight (LOS) model for communicating devices in modern indoor environment.

The provision of Wireless Fidelity (Wi-Fi) service in an indoor environment is a crucial task and the decay in signal strength issues arises especially in indoor environments. The Line-of-Sight (LOS) is a path for signal propagation that commonly impedes innumerable indoor objects damage signals and also causes signal fading. In addition, the Signal decay (signal penetration), signal reflection, and long transmission distance between transceivers are the key concerns. The signals lose their power due to the existence of obstacles (path of signals) and hence destroy received signal strength (RSS) between different communicating nodes and ultimately cause loss of the packet. Thus, to solve this issue, herein we propose an advanced model to maximize the LOS in communicating nodes using a modern indoor environment. Our proposal comprised various components for instance signal enhancers, repeaters, reflectors,. these components are connected. The signal attenuation and calculation model comprises of power algorithm and hence it can quickly and efficiently find the walls and corridors as obstacles in an indoor environment. We compared our proposed model with state of the art model using Received Signal Strength (RSS) and Packet Delivery Ratio (PDR) (different scenario) and found that our proposed model is efficient. Our proposed model achieved high network throughput as compared to the state-of-the-art models.

Abstract In this paper, the digital twin platform for the indoor environment is constructed by combining digital twin technology and modern indoor environment elements to innovate the modern indoor environment design method. The digital twin platform is designed for modern indoor environments in two aspects: data acquisition and 3D model visualization for indoor environments. The indoor environment data are collected, cleaned and quasi-exchanged using sensors, the collected multi-source heterogeneous data of the indoor environment are fused by the time alignment method, and the 3D model of the indoor environment is driven by the design of the 3D model’s operations of translation, rotation and scaling. On this basis, the performance of the indoor environment digital twin platform is analyzed, and the data acquisition method and driving effects of the 3D model are explored. The results show that the data transmission measurement delay is within 20ms, the display delay is within 70ms, the transmission frames per second are basically stabilized at about 200FPS, 100FPS, 60FPS, the accuracy reaches 0.9 in the case of multiple data acquisition, and the fusion speed is about 3.4m/s, and the success rate of the driving operation of the overall three-dimensional model of the indoor environment is all greater than 0.96.

The effect of different systems of growing tomatoes in a protected area on morphological properties and business results

We are witnessing negative consequences caused by the use of synthetic crop protection products and fertilizers in food production. Interest in the indoor farming of certain plant species has grown significantly. Organic and integrated farming imply the use of natural products, while limiting or completely eliminating the use of synthetic resources. The goal of the research is to study different farming systems in two types of tomatoes and their effect on the variability of certain tomato properties (the number of formed flower trusses, number of fruits per flower truss, and tomato yield). Furthermore, the gross margin of tomato production was calculated. Factor A comprised of different systems of agricultural production: integrated and organic. Factor B comprised two types of tomatoes (cherry and beef). The experiment was set up in a modern indoor space, in controlled microclimate conditions in randomized block design in four replications. The organic system of farming highly significantly affected the studied parameters. The reason for this was the use of a modern growing technology and the approach to the farming itself.

Characteristics of Dye-Sensitized Solar Cell under PWM Illumination: Toward Indoor Light-Energy Harvesting in the Solid-State Lighting Era

The dye-sensitized solar cell (DSSC) has been on the market as a permanent power source for indoor IoT edge devices. In recent years, indoor illumination technology has been experiencing a drastic transition from incandescent and fluorescent lamps toward solid-state lighting devices with light-emitting diodes (LEDs). In addition to the high power efficiency, a virtue of LEDs is their prompt response, which enables precise change of the illumination level using pulse-width modulation (PWM) of the current source, and thus PWM illumination is commonly installed in society. The light intensity change from off to on states of an LED under PWM driving is literally infinity, which causes the lighting to flicker. The lighting flicker induces not only an optical illusion but also biological effects, including serious health problems, which can be mitigated by raising the modulation frequency. Because the peak intensity of a PWM illumination can be 100 times that of the average intensity, the indoor solar cell, which has a relatively high series resistance, is expected to underperform. In this paper, the characteristics of a commercial indoor DSSC under PWM illumination are studied. It is found that while PWM illumination at low frequency seriously deteriorates the performance of the DSSC, it recovers at high frequency. The latter feature is not found in indoor amorphous-Si solar cells, and the electrochemical impedance spectroscopy revealed that it stems from the electrochemical nature of some components of the series impedance in the DSSC, offering a key piece of evidence of the superiority for use in the modern indoor application of the DSSC over traditional amorphous-Si solar cells.

Audio transmission through tunable CCT lighting system: A novel approach of VLC beyond static lighting

In this article a novel approach of visible light communication (VLC) through tunable correlated color temperature (CCT) lighting system has been demonstrated. Till date VLC has been demonstrated through either fixed CCT white LED light source or a single color LED light source. But recent research on photo biological and psychological effect of lighting on human health shows that tunable CCT lighting system is better for human health compared to fixed CCT lighting system. Modern indoor smart lighting system is also adopting the tunable CCT light sources for illumination. Hence, the concept of VLC through static lighting should also be changed. Here, to prove the concept, an audio transmission channel through tunable CCT lighting source has been designed, developed and experimentally validated. A phosphor coated warm white, single colored green and blue (WGB) LED based tunable CCT light source has been developed. The experiments have been performed for the tunable CCT range from 2800 K to 12000 K, maintaining the illuminance 200 lx on the working plane. The real time audio signal has been transmitted through it without affecting the CCT and illuminance. The maximum deviation in CCT is 137 K when set CCT is 12000 K, frequency and amplitude of the audio signal is 100 Hz and 400 mV respectively. The pulse width modulation (PWM) technique has been used for transmitting the audio signal. The communication range is 228.6 cm, which is the general distance between ceiling and the working plane.

Access to Daylight at Home Improves Circadian Alignment, Sleep, and Mental Health in Healthy Adults: A Crossover Study.

As the primary environmental cue for the body’s master biological clock, light–dark patterns are key for circadian alignment and are ultimately fundamental to multiple dimensions of health including sleep and mental health. Although daylight provides the proper qualities of light for promoting circadian alignment, our modern indoor lifestyles offer fewer opportunities for adequate daylight exposure. This field study explores how increasing circadian-effective light in residences affects circadian phase, sleep, vitality, and mental health. In this crossover study, 20 residents spent one week in their apartments with electrochromic glass windows and another week with functionally standard windows with blinds. Calibrated light sensors revealed higher daytime circadian-effective light levels with the electrochromic glass windows, and participants exhibited consistent melatonin onset, a 22-min earlier sleep onset, and higher sleep regularity. In the blinds condition, participants exhibited a 15-min delay in dim light melatonin onset, a delay in subjective vitality throughout the day, and an overall lower positive affect. This study demonstrates the impact of daytime lighting on the physiological, behavioral, and subjective measures of circadian health in a real-world environment and stresses the importance of designing buildings that optimize daylight for human health and wellbeing.

Identification of high-performance volleyball players from anthropometric variables and psychological readiness: A machine-learning approach

Modern indoor volleyball has evolved into a high-level strength sport and is seen as one of the most popular open-skilled team sports. The nature of the sport as an open-based skill requires players to have a high degree of both psychological skill and physical ability to cope with the sport’s externally and internally induced pace. The purposes of this study were to examine the essential basic anthropometric variables, as well as competition and practice psychological readiness, that could provide a performance edge and identify high and low-performance players based on the parameters. The anthropometric variables of height, weight, and age were assessed, while the test for performance strategies instrument was used to evaluate competition and practice psychological readiness skills of the players. The players’ performances were analyzed in real-time during a volleyball tournament. The Louvain clustering algorithm was used to determine the performance class of the players with reference to the variables evaluated. A total of 45 players were ascertained as high-performance volleyball players (HVP), while 20 players were deemed as low-performance volleyball players (LVP) via the clustering analysis technique. The logistic regression classifier was used to classify the performance of the players. Nonetheless, owing to the skewed representation between the HVP and LVP during the training of the model, the Synthetic Minority Oversampling TEchnique (SMOTE) was employed to artificially increase the minority class dataset to avoid the overfitting notion upon classification. It was shown from the study that, through the machine learning pipeline developed, an excellent identification of the HVP and LVP could be attained. The findings could be invaluable to coaches and other relevant stakeholders in team preparation and the selection of high-performance players in volleyball.

‘The question of the corset’: fashion, health and identity in late Ottoman history

ABSTRACT This article examines discussions on the corset in the illustrated press, text-book for girls, and medical and advice literature in the reign of Sultan Abdülhamid II (1876–1909). The article argues that the corset functioned as a cultural benchmark establishing the terms of Ottoman Muslim female sartorial decorum in a larger medicalized public debate on modern indoor dress. Hamidian reformers responded to a set of intertwined but rather conflicting requirements placed upon Ottoman Muslim women’s bodies, then positioned as the central pillars in Muslim community building. Caught between consumer desires for fashion, and the health, of the Muslim population, and stalled by a traditional discourse to regulate female indoor dress, Hamidian reformers mobilized a medicalized discourse associating dress, health and patriotism. Debates over the corset insisted on authentic Ottoman Muslim femininity by drawing upon the binaries of fashion against health, foreign against Muslim, and beautification against beauty. Corset debates opened the path towards shifting female beauty and its preservation from an individually pursued private aesthetic into a scienticized public debate which represented moral virtue and patriotic duty towards the larger goal of communal and imperial wellbeing.

Performance evaluation method of dye-sensitized solar cell under modulated illumination

The organic solar cell is promising as a permanent power source for indoor IoT devices. Dye-sensitized solar cells (DSSC) have been commercialized for this purpose. On the other hand, LED-based solid-state lighting is commonly chosen as the modern indoor lighting source, and most of them have a dimming function by pulse width modulation. In this article, the performance evaluation method of DSSC under modulated illumination is studied. When the modulation frequency competes with the power-line frequency set to the measurement apparatus for the rejection of the error from the power-line, the mismatch between them causes serious fluctuation in current-voltage curves. The averaging induces another problem, noticeable hysteresis. Removing the mismatch between the two frequencies is found as the proper way to eliminate the fluctuation.
