Precise Indoor Path Planning Based on Hybrid Model of GeoSOT and BIM

With the improvement of urban infrastructure and the increase in the coverage of high-rise buildings, the demand for location information services inside buildings is becoming more and more urgent. Moreover, indoor path planning, as a prerequisite and basis for realizing path guidance inside buildings, has become a research focus in the field of location services. This makes the accurate planning of indoor paths an urgent problem to be solved at present. This requires dynamic and precise planning from static fuzzy planning, and the corresponding scene converted from a two-dimensional plane to a three-dimensional one. However, most of the existing indoor path planning methods focus on the use of two-dimensional floor plans in buildings to build indoor maps and rely on traditional path search algorithms for pathfinding, which lack in the efficient use of the building’s own geometric and attribute information and lack consideration of the internal spatial topology of the building, making it difficult to meet the needs of indoor multi-layer continuous space path planning. Considering this relationship, it is difficult to meet the path planning needs of indoor multi-layer continuous spaces. In addition, the two-dimensional expression dominated by arrows and line drawings also greatly reduces the intuitiveness and interactivity of path expression. Regarding this, this paper combines the GeoSOT grid with accurate real geographic information and the BIM model and proposes an accurate indoor path planning method. Finally, using Guanlan Commercial Street in Baiyin City as the experimental object, the precise planning and generation of indoor paths and the interaction of visual displays on the web page are realized. It has been verified that the method has certain reference and application values for meeting the demand of location information services in buildings and building an integrated indoor–outdoor navigation service platform.
Testing a Model to Monitor Training Effect in Distance Running

A new way to determine training-induced changes in maximal aerobic running speed (MAS), the MAS Training Effect Model, has been developed. In addition to the effect of single exercise induced fatigue and adaptation on MAS, the model takes account of individual training status, specificity of training, decreased training and detraining. After describing the model in detail, the authors present the results of a study to evaluate the validity of the model’s ability to estimate training effect through changes in MAS during a long-term training period. Fifty-three recreational distance runners took part in a 28-week training programme, during which endurance performance characteristics like MAS and VO2max were determined three times for each runner. The changes in MAS did not correlate with any variable describing the volume or intensity of the training followed, but a significant correlation was observed between the measured and estimated changes in MAS using the new model (r = 0.364, P = 0.007). It was concluded that the model is valid for monitoring changes in MAS in a long-term training period, even if it does not account for all the individual and non-training stress factors that impact training effect in endurance running.
Childhood, Curriculum, and Culture in Diverse Contexts

Children acquire and inherit cultural values and rules by interacting with the surroundings they live in (Fleer, 2017). The surroundings include both physical and psychological contexts, such as children’s play and literature, which mirror the cultural image of childhood (Frønes, 2009; Tesar et al., 2019). It is also important to pay equal attention to both “education” and “care” in early childhood, something that traditionally varies across diverse curricula and cultures (Ailwood, 2022). In addition, many other factors may play a role in mediating or moderating the influences from culture to childhood, such as new media, religion, leisure activities, fairy tales, digital games, and curricula. All these factors are, directly or indirectly, influenced by culture. Thus, the path from culture to childhood development varies across contexts. Likewise, the mediating role of childhood curricula also varies across cultures. This implies that culture plays an important role in shaping the childhood curriculum.
Refractometric Detection of Adulterated Milk Based on Multimode Interference Effects

This paper reports on the refractometric detection of water-adulterated milk using an optical fiber sensor whose principle of operation is based on multimode interference (MMI). The device is manufactured in a simple way by splicing a segment of coreless multimode fiber (NC-MMF) between two single-mode fibers (SMFs); neither functionalization nor deposition of a sensing material is required. MMI takes place in the NC-MMF and, when fed with a broadband spectrum, a transmission peak appears at the output of the MMI device due to its inherent filter-like response, whose position depends on the effective refractive index (RI) of the medium surrounding the NC-MMF. Therefore, when the sensor is immersed in different milk–water mixtures, the peak wavelength shifts according to the RI of the mixture. In this way, adulterated milk can be detected from the wavelength shift of the transmission peak. The system was tested with two commercial brands of milk, and adulterations were clearly distinguished in both cases. In the range of interest, from no dilution up to 50% dilution, the sensor exhibits a linear response with a sensitivity of −0.04251 and −0.03291 nm/%, respectively, for the two samples tested. The measurement protocol is repeatable and allows for locating the peak wavelength within <0.34 nm over several repetitions using different samples with the same concentration. A thermal sensitivity of 0.85 nm/°C was obtained, which suggests that the temperature needs to be maintained as fixed during the measurements. The approach presented can be extended to other scenarios as a quality control tool in beverages for human consumption, showing the advantages of simple construction, high sensitivity, and the potential for real-time monitoring.
Effect of Impeller Trimming on Centrifugal Pump

Pumps, especially centrifugal pumps, play an important role in engineering application, such as petroleum and petro-chemical industries, agricultural industries, portland cement industries etc. To obtain the best performance of the pumps, one has to operate the pumps at their design conditions. In some circumstances, however, the pumps must operate lower than their design conditions and result in the decrease in their performances. In such cases, it is possible to replace the pump impeller with the smaller impeller diameter or to cut its original impeller to smaller size as necessary. The cut of the impeller, or it is frequently referred to as impeller trimming, in some extence is preferable than replacing with new impeller or even by replacing with new pump with smaller head and capacity. In this study, we examine the effect of the pump impeller trimming to the pump performaces. The study was performed in the Fluid Mechanics Laboratory, Mechanical Engineering Department of ITS, Surabaya. The pump impellers were cut up to approximately 19 percent of its original pump impeller diameter, where the original pump impeller diameter is 129 mm. The pump has the maximum capacity of 100 liters/min and the total head of 31.5 m. The pump is powered by a 300 Watt electrical motor. Parameters to be studied in this research include pump capacity, pump head, pump power, and pump efficiency. The results of this study show that all data are in good agreement with the pump affinity laws. Pump capacity, pump head, and pump power decresase as the pump impeller diameter decreases. The pump efficiency is, however, in some extent, increases as the pump impeller diameter decreases. The maximum increase in pump efficiency is obtained when the ratio between the trimmed impeller to its original pump impeller diameter is approximately 89 percent (i.e. D2/D1 = 0.89), with the increase in pump efficiency of approximately 20 percent.
Low-Power Switching Scheme with Quarter Reference Voltage Sources for SAR ADCs

In this paper, an energy-efficient switching scheme with additional quarter-reference voltage sources in a successive approximation register (SAR) analog-to-digital converter (ADC) is proposed for a low power and small area device for frequency modulated continuous wave (FMCW) radar transceivers. Recently, state-of-the-art ADCs have adopted a configuration that also uses Vref/2 as the reference voltage of the ADCs to improve the switching energy of capacitive digital-to-analog converter (CDAC). The proposed switching configuration additionally uses Vref/4 and 3Vref/4 reference voltages as the reference voltage of CDAC. Compared to state-of-the-art configurations that use the additional reference voltage of Vref/2, the average switching energy, and the total capacitance of CDAC in the proposed configuration are reduced by about 87.5% and 50%, respectively. In this switching scheme, the CDAC output voltage gradually converges to Vref/2, like with conventional SAR ADCs, which minimizes the dynamic offset that deteriorates the linearity of the SAR ADC.
Corporate governance and earnings management: Does gender matter?

This study aims to analyse the extent to which corporate governance is able to influence earnings management when moderated by the presence of woman in board of directors. Independent variables used in this study were board independence, board meeting, board size, managerial ownership, ownership concentration, institutional ownership, audit quality, and firm size. This study used the financial data from the companies that are registered in Indonesia Stock Exchange from 2015-2019. The total 1,749 data were tested using multiple linear regression analysis. The results show that board independence has significantly positive effect, while firm size have negatively significant effect on earnings management when the relationship is moderated by board gender diversity. The other variables do not show significant results. This study contributes to the provision of inputs to the literature development related to governance idea proposing that the woman factor in governance can be important for the company control. In addition, this study has the implication for companies to analyse good corporate governance and consider the role of woman in the company management.
Adiabatic CMOS-Based Electrostatic MEMS Actuation for Reduced Dynamic Power and Switching Activity

The basic purpose of MEMS actuation is to miniaturize the actuators and sensors for applications in nanoelectronics. The transistor switching current and power supply noises due to voltage drops across the metal lines can impair circuit timing and performance, posing a continuing problem for high-performance chip designers. This work presents an empirical concept of a reconfigurable charge pump based on FPGA for electrostatic actuation of the Microelectromechanical System (MEMS). The goal of the design is to produce enough on-chip voltages for actuating the MEMS that are continuously adaptive and reconfigurable. In this proposed method, pumping capacitors lying in the range of 1-pF have been deployed to decrease the area of design concerned. The various voltages are programmable digitally and created by dynamically altering the number of phases as well as the clock drive levels. The dynamic model is designed by adjusting the number of stages to produce on-chip voltages including clock drive speeds, assuming a purely capacitive load. The proposed model’s power consumption can be lowered in the steady state by lowering its clock frequency and electrostatic MEMS actuators with capacitive load. An average of 0.62 W is dissipated by the circuit when the eight stages are triggered. Consequently, with adiabatic and without adiabatic architecture, 0.0186 mW of minimum power difference is obtained.
Japanese people's attitudes toward acculturation and intercultural relations

Dealing with cultural diversity is one of the key challenges in contemporary societies, with Japan being no exception. However, relatively little is known about how minority group members are viewed by members of the dominant group. The current paper presents a study that evaluated three hypotheses that are related to these issues with a survey of 210 Japanese adult participants. The study also examines moderating roles of national identities in acculturation expectations and psychological functioning in the dominant group. Perceived security about the society in terms of national culture, and personal conditions in a multicultural society predict the most tolerant form of acculturation expectation. This association is mediated by one's multicultural ideology. Although acculturation expectations are not predictive of psychological functioning, particular national identity (i.e., internationalism) alleviates the negative effect of the closest form of expectation (exclusion) on psychological problems. The study implies the need for analysis on culture-specific constructs of multicultural society in perceptions and attitudes in the dominant group in Japanese society.
Modulating Wave-Based Timing Calculation for a Multilevel 24-Sided Polygonal Voltage Space Vector Structure With Similar Triangles

This article proposes a multilevel 24-sided polygonal voltage space vector structure (VSVS), eliminating lower order harmonics up to 19th order and suppressing higher order harmonics in motor phase voltage throughout the modulation range. Unlike switched average vectors in literature, the proposed scheme generates real active vectors that have the advantage of less switching frequency operation. The proposed VSVS consists of two concentric polygons divided into similar triangles resulting in a simple modulation algorithm. Instantaneous error in phase voltage reduces due to the multilevel property of the proposed VSVS. The proposed scheme extends the dc bus utilization and linear range of operation. The proposed scheme is implemented on an open-end winding induction motor fed with primary and secondary inverters from either end. This article also presents a modulating wave-based method to compute nearest vector timings using sampled reference waves only. Unlike conventional methods, the proposed timing calculation method does not require trigonometric operations, sorting algorithms, and iterative search algorithms. Experimental verification of the proposed scheme is performed to validate the concept. Switching loss and Fourier analysis comparison with some existing schemes is also presented.
Speech-Language Pathologists’ Self-Reported Language Input and Recommendations During Early Intervention

This study examined the extent to which early intervention (EI) speech-language pathologists (SLPs) use and recommend language input strategies for caregivers of children with language delays and the child factors associated with these decisions. Participants included 213 SLPs who completed an online survey. Wilcoxon signed-rank tests, Friedman’s analyses of variance, and Spearman correlations were used to determine the extent to which EI SLPs used and recommended language input, child factors that influenced recommendations and input, and relationships between SLPs’ self-reported strategies and recommendations to caregivers. EI SLPs reported recommending expanding on child utterances more than other strategies. EI SLPs reported using grammatical input more than telegraphic input and recommended grammatical phrases as children made gains in spoken language. Language strategies used by SLPs inconsistently aligned with their recommendations to caregivers. Results underscore the importance of evaluating recommendations to caregivers in the context of EI.
Biological roles and clinical significance of estrogen and androgen receptors in head and neck cancers

Head and neck cancers (HNC) include malignant tumors that grow in and around the mouth, larynx, throat, sinuses, nose, and salivary glands. Accumulating evidence in malignancies suggests the aberrant expressions of the estrogen receptor (ER) and the androgen receptor (AR) in HNC, such as in laryngeal cancer and cancer of the salivary gland. Moreover, the signaling pathways involving these receptors that mediate tumorigenesis, proliferation, apoptosis, migration, and invasion have been elucidated. This review summarizes the roles of ER and AR with the putative signaling pathways involved in HNC. We also discuss the potential application of ER- and AR-related therapies in HNC. However, most of the mechanisms underlying AR and ER involvement in the development of HNC remain elusive and warrant further studies. A comprehensive understanding of the functional roles and mechanisms of action of AR and ER in HNC will facilitate the development of better therapeutic strategies for this disease. Overall, studies on AR and ER provide a promising potential for the diagnosis and treatment of HNC in the future.
Use of Simple Octa-Ring Configuration for Tunable Erbium Laser With Single-Mode Output

In this paper, an erbium-doped fiber (EDF) octa-ring laser system with continuous-wave (CW) tunability and stable single-longitudinal-mode (SLM) output is presented and investigated. The octa-ring configuration can cause a mode-filter operation based on the Vernier effect for dense side-mode suppression and gain extension. Therefore, the available wavelength-tuning bandwidth of the laser can be achieved from 1519.0 to 1575.0 nm by utilizing conventional C-band EDF based gain-medium. Moreover, the output power, output stability, optical signal to noise ratio (OSNR) and laser linewidth of the demonstrated EDF laser are also executed and discussed.
Clinical Implications of Circulating Circular RNAs in Lung Cancer

Circular RNAs (circRNAs) are single-stranded RNAs with a covalently closed-loop structure that increases their stability; thus, they are more advantageous to use as liquid biopsy markers than linear RNAs. circRNAs are thought to be generated by back-splicing of pre-mRNA transcripts, which can be facilitated by reverse complementary sequences in the flanking introns and trans-acting factors, such as splicing regulatory factors and RNA-binding factors. circRNAs function as miRNA sponges, interact with target proteins, regulate the stability and translatability of other mRNAs, regulate gene expression, and produce microproteins. circRNAs are also found in the body fluids of cancer patients, including plasma, saliva, urine, and cerebrospinal fluid, and these “circulating circRNAs” can be used as cancer biomarkers. In lung cancer, some circulating circRNAs have been reported to regulate cancer progression and drug resistance. Circulating circRNAs have significant diagnostic value and are associated with the prognosis of lung cancer patients. Owing to their functional versatility, heightened stability, and practical applicability, circulating circRNAs represent promising biomarkers for lung cancer diagnosis, prognosis, and treatment monitoring.
Performance Evaluation of Energy Consumption of Ad hoc Routing Protocols

In wired networks there are different physical devices routing the traffic centrally, by consequence we can create paths in the network by using multiple management rules, but in Ad-Hoc network nodes must do this work in an autonomous way. For that there are three types of routing protocol proactive, reactive and hybrid. The first one continuously calculates the possible paths to be available at the time of transmission. The second one create the roads only when are needed. And the last one is a combination between the two methods. In this study we will focus on three routing protocols AODV, OLSR and ZRP; and compare their performance in terms of Routing Power, Throughput, Energy Consumed in Transmit mode, Energy Consumed in Receive Mode, End-to-End Delay.
Design and Fabrication of an Unmanned Aerial Vehicle

The military utilization of Unmanned Aerial Vehicles (UAVs) has improved effectively day by day due to their capacity to carry out the desired work in hazardous and hostile environments while keeping their human administrators at a protected distance. The bigger UAVs likewise give a reliable long span, cost effective platform for observation and in addition weapons. They have been developed to be transformed into an imperative apparatus for the military. The question postured for the project was whether small UAVs additionally had utility in military and business/mechanical applications. It was proposed that smaller UAVs can serve more strategic operations, for example, seeking a village or a building for adversary positions and in addition for completing little scale transportation and conveyance meets expectations in different businesses and marketing endeavors. To accept this suspicion and considering various UAV outlines it was chosen to outline and create a Quadcopter. In this project the primary point is to build up a quadcopter that can be controlled by a straightforward flight controller. With a high payload limit this can be utilized for doing transportation and in addition outside observation as well as surveillance
Continuous Estimation of Finger and Wrist Joint Angles Using a Muscle Synergy Based Musculoskeletal Model

Recently, many muscle synergy-based human motion prediction models and algorithms have been proposed. In this study, the muscle synergies extracted from electromyography (EMG) data were used to construct a musculoskeletal model (MSM) to predict the joint angles of the wrist, thumb, index finger, and middle finger. EMG signals were analyzed using independent component analysis to reduce signal noise and task-irrelevant artifacts. The weights of each independent component (IC) were converted into a heat map related to the motion pattern and compared with human anatomy to find a different number of ICs matching the motion pattern. Based on the properties of the MSM, non-negative matrix factorization was used to extract muscle synergies from selected ICs that represent the extensor and flexor muscle groups. The effects of these choices on the prediction accuracy was also evaluated. The performance of the model was evaluated using the correlation coefficient (CC) and normalized root-mean-square error (NRMSE). The proposed method has a higher prediction accuracy than those of traditional methods, with an average CC of 92.0% and an average NRMSE of 10.7%.
Inertial particle focusing in microchannels with gradually changing geometrical structures

The influence of gradually changing geometrical structures on the inertial focusing of particles is systematically investigated by numerical simulations and experiments in this paper. The Saffman lift force, often ignored in the straight microchannel, becomes strong in microchannels with gradually changing geometrical structures, affecting the lateral migration of particles in the microchannels. In comparison with microchannels that have straight and gradually constricting structures, microchannels with gradually expanding structures focus all the particles in a much narrower bandwidth due to the combined effect of the Saffman lift force and the inertial lift force at the appropriate flow rates. Additionally, the influence of the different arrangements of gradually expanding structures on the inertial focusing of particles was also studied. Results suggest that to achieve the single-stream inertial focusing of particles, gradually expanding structures should be designed on one side or symmetrically on two sides of the microchannel. This study is of importance for the better design of the microchannels utilized for the efficient separation and manipulation of particle-related applications, such as microflow cytometry.
