An essential location analytic method is GIS, able to support map-based display along with geographic data creation, management, manipulation in addition functions for suitability evaluation. Location models have proven be critical as well, many prominent approaches found popular GIS software. This paper reviews a class of and provides an overview the methods used solve these models. significant because broad use application address important problems issues facing society. Spatial...
Background Hand-foot-and-mouth disease_(HFMD) is one of the most typical diseases in children that associated with high morbidity. Reliable forecasting crucial for prevention and control. Recently, hybrid models have become popular, wavelet analysis has been widely performed. Better prediction accuracy may be achieved using wavelet-based models. Thus, our aim to forecast number HFMD cases Materials methods We fitted a seasonal autoregressive integrated moving average (SARIMA)–neural network...
Total demand suitably served and facility workload balance are two important considerations in location coverage. Previous work has dealt with balancing issues using a number of approaches, including imposing capacities the use multiple objectives focused on variation. However, is usually restricted to single service unit, inconsistent strategies that allow for increased staffing such as units dealing higher levels demand. This article proposes new bi‐objective optimization model maximizes...
Neural network-based inverse design of nanophotonic device network is computationally and time efficient, but in general suffers the problems robustness stability against variation input target electromagnetic response. The required to be robust response capable approximating given response, even under circumstances that exact may not exist. We introduce a modified denoising autoencoder ensure neural design, which consists (1) pre-trained as substitute numerical simulation (2) an network....
Abstract Service system planning has long been supported by location‐covering models designed to address access and accessibility issues. An important aspect of many systems is limits on service, often conceptualized as facility capacities. Much research can be found that proposes modeling approaches solution techniques account for capacitated covering problems, commercial GIS software exists capable structuring applying service limits. This article reviews issues challenges associated with...

Abstract Background: Hand-foot-and-mouth disease(HFMD) is one of the most common diseases in children, which has high morbidity. Reliable forecasting significant for prevention and control. Recently, hybrid models have been becoming popular wavelet analysis widely used. Better prediction accuracy may be achieved with wavelet-based models. Thus, our aim to forecast number HFMD cases Materials methods: We fitted a SARIMA(seasonal autoregressive integrated moving average)-NNAR(neural network...
This paper presents an approach for finger motion classification using a single-site mechanomyography (MMG) signal that utilizes high-resolution and selected proper features by optimized-long short-term memory (Opt-LSTM) as the main pattern recognition components. A pair of MMG sensors are employed comprising piezoelectric strain gauges to record contracting muscles emitting low-frequency mechanical vibrations on skin's surface. Then, multimode high-dimensional extracted from time-,...
One pressing concern for coal-fired power plants is the retrofitting of heating supply, as central demand continues to rise, and carbon emission reduction becomes a priority. However, cogeneration heat leads unwanted heat-power coupling restricts peak-shaving flexibility. In this study, pump used in designing highly efficient decoupling retrofit systems. Three cases integrating absorb (AHP) electric (EHP) are proposed. Their energy utilization efficiency, exergy coal consumption with varying...
Locating facilities such as directional sensors and lights represents a challenging problem given their anisotropic coverage. This paper proposes spatial optimization model to locate orient simultaneously. A finite dominating set approach considering occlusion is presented reformulate the an integer programming problem. The then solved exactly using branch bound. Applications surveillance camera deployment in university context demonstrate performance of proposed approach. results show...
Districting is essential in establishing efficient, fair, and equitable boundaries across various domains such as trade service provision, land-use development, school attendance, political representation. This paper introduces a robust spatial optimization model tailored to delineate districting strategy that accounts for issues of equinumerosity, compactness, contiguity, among others. The designed ensure an even distribution population districts while ensuring compact contiguous...
Bloom Filter is a bit array (a one-dimensional storage structure) that provides compact representation for set of data, which can be used to answer the membership query in an efficient manner with small number false positives. It has lot applications many areas. In this paper, we extend design by using multi-dimensional matrix replace structure three different implementations, namely OFFF, WOFF, FFF. We refer extended as Feng Filter. show positive rates our method. compare rate OFFF...
