Ablative carbon dioxide fractional laser (CO2 AFL) can alleviate static wrinkles; however, its use in East Asian populations predispose them to postinflammatory hyperpigmentation (PIH). We aimed explore the optimum energy and coverage parameters of CO2 AFL for treating periorbital wrinkles a Chinese population minimize PIH incidence. In total, 30 patients with were recruited. The intervention side (1% hydroquinone cream every night on one area each patient 1 month before from 8th day after...

Max-plus algebra is a suitable algebraic setting to model discrete event systems involving synchronization and delay phenomena which are often found in transportation networks, communications systems, manufacturing systems. One way of controlling this kind consists choosing the dates input events order achieve desired performances, e.g., obtain output respect given dates. This control optimal, according just-in-time criterion, if input-event delayed as much possible while ensuring occur...

The max-plus linear systems have been studied for almost three decades, however, a well-established system theory on such specific is still an on-going research. geometric control in particular was proposed as the future direction by Cohen et al. This paper reports upon recent investigations disturbance decoupling problem systems, which standard originated W. M. Wonham. Different concepts of are introduced, well corresponding solvability conditions and controller synthesis procedures. main...

When using current methods to predict electricity theft behavior, there are problems of large sample data errors before training, high line loss rate, and low prediction effect. To this end, a power-stealing behavior method based on multi-dimensional features BP neural network is proposed. The first extracts the abnormal power usage characteristics according user's behavior. Then genetic algorithm used optimize network, optimized train consumption characteristics. Finally, model established...

Based on the existing research work modeling and control of cyclically operated high-throughput screening systems, this paper presents scheduling systems with uncertainties disturbances. Different definitions disturbance decoupling problems are considered in order to achieve optimal systems. Online was achieved by computing prefilters output feedback controllers, which can be computed using residuation theory. The strategies controllers sense just-in-time criterion commonly used industrial...

This paper presents the new investigations on disturbance decoupling problem (DDP) in geometric control of max-plus linear systems. Due to monotone nondecreasing property systems, a modified (MDDP) is defined and an optimal controller solve MDDP obtained using prefilter mapping by taking disturbances into account. Moreover, this necessary sufficient condition such that same for can be used DDP When not satisfied, developed order guarantee solvability MDDP. The main results are illustrated...

In recent years, as bitcoin's value continued to climb, theft electricity by bitcoin mining user began appear. order solve problem users, conducted an in-depth study on consumption such users based data analysis technology. This paper analyzes characteristics uses acquire system monitor behavior. The makes comparative massive voltage acquisition system,...

Abstract Reinforcement learning (RL) has been used to optimize the continuous integration (CI) testing, where reward plays a key role in directing adjustment of test case prioritization (TCP) strategy. In CI frequency is usually very high, while failure rate cases low. Consequently, RL will get scarce rewards which may lead low efficiency and even difficulty convergence. This paper introduces three tackle issue sparse testing. First, historical density‐based ( H F D ) defined, objectively...

For a long time, power supply enterprises have been plagued by the problem of electricity theft and default. Although strengthened anti-theft measures from various aspects, huge benefits brought default driven development trend methods to be more complicated concealed, which has great challenges work. In order quickly accurately locate suspected users "defaulting on consumption stealing electricity", based massive data marketing business application system information collection system, this...

Max-plus linear systems are often used to model timed discrete-event systems, which represent system operations as discrete sequences of events in time. This paper presents the observer-based controller solve disturbance decoupling problem for max-plus where only estimations states available controller. leads a greater control input than one obtained with output feedback strategy based on just-in-time criterion. A high throughput screening drug discovery illustrates this main result by...

Antioxidant activity system was closely related plant growth reproduction as well human health. This study investigate some other potential from a range of primary secondary metabolites by comparison antioxidant between six pairs GMOs their nontransgenic...

In this paper, a zero semimodule for linear system over semiring is introduced. Unlike field, an (A, B)-controlled invariant sub-semimodule V not equivalent to of feedback type V/sub FB/. The solvability condition the disturbance decoupling problem (DDP) cannot be established by knowing maximal sub-semimodule. extended used find tight upper bound FB/*, if one exists. Thus connection between geometric control method and frequency domain method. This implies necessary DDP. For example systems...
