Abstract:

These research tasks present a measurement platform of Bluetooth asynchronous links in order to get the intrinsic time constraints of this network and communications protocols. These time measurements are necessary for the application we wish to implement for mobile robot control through Bluetooth link communication. We present the platform as well as the measurement protocol which we have carried out from real-time communicating operating systems. We have developed an application of radio and time data processing allowing a real-time evaluation of the global behavior of the communicating syst

Abstract:

Health outcomes measurement has not fulfilled its potential. An important reason is the inability of the systems in place to properly utilize the information provided by outcome indicators to improve care. This paper describes a measurement framework that empowers healthcare professionals to act on information that is provided by using logical predetermined protocols. The benefits of this framework include enhanced evidence-based healthcare processes, organizational learning through knowledge generation and dissemination, and improved health outcomes.

Abstract:

Amplification of quantum states is inevitably accompanied with the introduction of noise at the output. For protocols that are probabilistic with heralded success, noiseless linear amplification in theory may still be possible. When the protocol is successful, it can lead to an output that is a noiselessly amplified copy of the input. When the protocol is unsuccessful, the output state is degraded and is usually discarded. Probabilistic protocols may improve the performance of some quantum information protocols, but not for metrology if the whole statistics is taken into consideration. We calc

Abstract:

Many researchers have analyzed sources of uncertainty in synchronization protocols for wireless sensor networks. However, very few researchers perform this work in depth, and failed to discover comprehensive characteristics since they worked with only one or two measurement intervals. To overcome this problem, extensive measurements were conducted and analyzed to find the characteristics of the sources according to various measurement intervals. Using the characteristics, a new media access control protocol, WideMAC, was designed to support a wide range of duty cycles for various applications.

Performance analysis of continuous-variable quantum key distribution (CVQKD) has been one of the focuses of quantum communications. In this paper, we propose an approach to enhancing the secret rate of CVQKD with the multi-core fiber (MCF) system that transmits multiple spatial modes simultaneously. The excess noise contributed by the inter-core crosstalk between cores can be effectively suppressed by quantum channel wavelength management, leading to the performance improvement of the MCF-based CVQKD system. In the security analysis, we perform numerical simulations for the Gaussian-modulated

Abstract:

Wireless avionics intra-communication (WAIC) refers to a wireless communication system among electronic components (e.g., sensors and actuators) that are integrated or installed in an aircraft and it is proposed to replace heavy and expensive wired communication cables. Recently, the use of a frequency band (4.2–4.4 GHz) for the WAIC (so-called, WAIC band) has been approved by international telecommunication union (ITU). Accordingly, several existing wireless protocols such as IEEE 802.11 and IEEE 802.15 are being considered as candidate techniques for the intra-avionics sensor network. In thi

Abstract Measurement of growth performances in fish is carried out in stressful and unnatural environment. The purpose of the present investigation was to compare the effect of four different water-borne anesthetic agents.

The vehicle-to-vehicle (V2V) propagation channel has significant implications on the design and performance of novel communication protocols for vehicularad hocnetworks (VANETs). Extensive research efforts have been made to develop V2V channel models to be implemented in advanced VANET system simulators for performance evaluation. The impact of shadowing caused by other vehicles has, however, largely been neglected in most of the models, as well as in the system simulations.

AbstractThe body composition phenotype of an athlete displays the complex interaction among genotype, physiological and metabolic demands of a sport, diet, and physical training. Observational studies dominate the literature and describe the sport-specific physique characteristics (size, shape, and composition) of adult athletes by gender and levels of competition. Limited data reveal how body composition measurements can benefit an athlete. Thus, the objective is to identify purposeful measurements of body composition, notably fat and lean muscle masses, and determine their impact on the heal

Internet of Things (IoT) applications can be used in healthcare services to monitor patients remotely. One implementation is that it is used to monitor COVID-19 patients. During the COVID-19 pandemic, people who are infected without symptoms must self-isolate so that the virus does not spread. Measurement of blood oxygen levels or SpO2 is one of the measurements that must be carried out in routine examination procedures for self-isolating patients for early detection of silent hypoxemia in COVID-19 patients.

There is a dearth of studies involving professional endurance athletes following a defined HRV-guided training protocol. The objectives of the proposed protocol are: (i) to determine change

Odour emission is as much a part of the adverse effect of any new or existing process as noise, water pollution, VOC emissions or radiation. It is essential to quantify it whenever plans are being made for new or modified processes. The first aspect of quantification of odour emission is the need to use a standard method of measurement of odour concentration. Aswith liquid effluents where we use standard laboratory methods for each characteristic, e.g. BOD, COD, TSS etc., the analysis method for measurement of odour concentration is the CEN/TC264/wg2 (draftprEN13725) standard (ComittéEuropéen

Abstract The repeatability of findings is the key factor behind scientific reliability, and the failure to reproduce scientific findings has been termed the ‘replication crisis’. Geometric morphometrics is an established tool in evolutionary biology. However, different operators (and/or different methods) could act as large sources of variation in the data obtained. Here, we investigated inter-operator error in geometric morphometric protocols on complex shapes of Liolaemus lizards, as well as measurement error in three taxa varying in their difficulty of digitalization.
