We used advanced technologies in this module to track patients suffering from heart failure and physical disorders. As a consequence, a heart rate sensor and a temperature sensor are utilized to track the patient. Sensors provide precise results, obviating the need for conventional medical instruments such as thermometers and other devices. GSM modem is used to transmit messages from the patient's position to the medical advisory. This module relieves medical advisors of the burden of patient monitoring while also allowing patients to travel about freely.

Research on trajectory tracking is crucial for the development of autonomous vehicles. This paper presents a trajectory tracking scheme by utilizing model predictive control (MPC) and preview-follower theory (PFT), which includes a reference generation module and a MPC controller. The reference generation module could calculate reference lateral acceleration at the preview point by PFT to update state variables, and generate a reference yaw rate in each prediction point. Since the preview range is increased, PFT makes the calculation of yaw rate more accurate. Through physical constraints, the

Fouling mitigation using chaotic advection caused by herringbone-shaped grooves in a flat membrane module is numerically investigated.

Typical flow characteristics include two counter-rotating flows and downwelling flows, which are highly influenced by the groove depth at each Re. Poincaré sections are plotted to represent the dynamical systems of the flows and to analyze mixing. The flow systems become globally chaotic as the groove depth incr

Also, membrane foulants were evaluated quantitatively.Methods : In this study, autopsy was performed for over 10 year old membranes used for drinking water purification. In this way, the outer casings of membrane modules at different positions were disassembled and visually observed. In add

The purpose of this study is to construct metal-organic framework (MOF) synthesis heating systems based on fuzzy method for monitoring and automatic control. In this study, the temperature sensing module for measurements sensed values that it through a wireless ZigBee chips and wired DAQ device for real-time data transmission. Because MOF synthesis, often due to different modes of heating or heating instability caused by its nucleation and crystal growth rate, is an important influence, leading to different crystallinity, the use of fuzzy theory to predict the temperature parameter and instant

The drying of seafood could ensure increase in life span, <em>minimization</em> of storage space, ease of transportation, etc of the product. It is therefore, necessary to dry and know when to stop drying at an appropriate moisture content that would minimize associated challenges in promoting food security. In this study, selected sea foods, such as prawn and oyster were obtained and then dried to determine their drying mass constants using model equation developed based on basic drying principle. The value of the constants obtained would provide data bank to facilitates prediction

Résumé :

Driven by the loss of bone calcium, the elderly are prone to osteoporosis, and regular routine checks on bone status are necessary, which mainly rely on bone testing equipment. Therefore, wearable real-time healthcare devices have become a research hotspot. Herein, we designed a high-performance flexible ultrasonic bone testing system using axial transmission technology based on quantitative ultrasound theory. First, a new rare-earth-element-doped PMN-PZT piezoelectric ceramic was synthesized using a solid-state reaction, and characterized by X-ray diffraction and SEM. Both a high piezoelectri

The Rolls-Royce integrated-planar solid oxide fuel cell (IP-SOFC) consists of ceramic modules with electrochemical cells printed on the outer surfaces. The cathodes are supplied with oxygen from air flowing over the outside of the module and the anodes are supplied with fuel diffusing from the internal gas channels. Natural gas is reformed into hydrogen in a separate reformer module of similar design except that the fuel cells are replaced by a reforming catalyst layer. The performance of the modules is intrinsically linked to the behavior of the gas flows within their porous structures. The m

Résumé :

Abstract Motivation Active module identification (AMI) is an essential step in many omics analyses. Such algorithms receive a gene network and a gene activity profile as input and report subnetworks that show significant over-representation of accrued activity signal (‘active modules’). Such modules can point out key molecular processes in the analyzed biological conditions. Results We recently introduced a novel AMI algorithm called DOMINO and demonstrated that it detects active modules that capture biological signals with markedly improved rate of empirical validation.

<strong>Purpose:</strong>The Kenya economy experienced an increase in the price of basic commodities, increased unemployment rates and consequently reduced real wage levels due to job cuts. An accurate forecast of this unprecedented inflation rate could have cushioned the Kenyan population from its effects. Uncertainty over future inflation forecasting has caused detrimental and negative impact not only globally but also in the Kenyan economy. Combining several techniques of forecasting is an instinctual way to improve prediction performance as the limitations of one method are compensated by

This article explores the interaction of Tense, Aspect and Modality in French, Italian and Spanish, languages in which Modals are inflected as main verbs. Imperfective modals are a-averidical, as modals are expected to be, but when they appear in a perfective tense, unexpected entailments and implicatures appear. For example, the following example is three-way ambiguous in Spanish; the corresponding example is two way-ambiguous in Italian and French: P. may have won, could have won, managed to win the race The three readings, epistemic, counterfactual and implicative, are derived from the alte

In modern society, the Internet is one of the most used means of communication. Thus, secure information transfer is inevitably of major importance. Computers nowadays use encryption methods based on arithmetic operations to turn messages into ciphertexts that are practically impossible for an attacker to reverse-engineer using a classical computer. Lately, it has been proven that this is possible in a post-quantum setting where quantum computers of considerable size are available to attackers. With the advance of technology of quantum computers, it is now more necessary than ever before to co

Several studies emphasize that the limited representation of Afro-Latinx communities in Spanish language curricula affects students’ understanding of the diversity in Spanish-speaking societies. However, research has yet to evaluate the impact of a curricular intervention incorporating an Afro-Latinx module into an L2 Spanish language course. The present study addresses two research questions: (1) what the changes in knowledge after implementing an Afro-Latinx module in an L2 Spanish language course are, and (2) how the module impacts students’ understanding of language variation and diversity

In this approach, a handcrafted algorithm along with the structural report is also analyzed for extracting further features of the gate level netlist, which stamp out the requirement of golden chip.

Module AbstractWhen investigating potential bias in educational test items via differential item functioning (DIF) analysis, researchers have historically been limited to comparing two groups of students at a time. The recent introduction of Moderated Nonlinear Factor Analysis (MNLFA) generalizes Item Response Theory models to extend the assessment of DIF to an arbitrary number of background variables. This facilitates more complex analyses such as DIF across more than two groups (e.g. low/middle/high socioeconomic status), across more than one background variable (e.g. DIF by race/ethnicity a
