As the role of predictive models has increased, the fidelity of computational results has been of great concern to engineering decision makers. Often our limited understanding of complex systems leads to building inappropriate predictive models. To address a growing concern about the fidelity of the predictive models, this paper proposes a hierarchical model validation procedure with two validation activities: (1) validation planning (top-down) and (2) validation execution (bottom-up). In the validation planning, engineers define either the physics-of-failure (PoF) mechanisms or the system performances of interest. Then, the engineering system is decomposed into subsystems or components of which computer models are partially valid in terms of PoF mechanisms or system performances of interest. Validation planning will identify vital tests and predictive models along with both known and unknown model parameter(s). The validation execution takes a bottom-up approach, improving the fidelity of the computer model at any hierarchical level using a statistical calibration technique. This technique compares the observed test results with the predicted results from the computer model. A likelihood function is used for the comparison metric. In the statistical calibration, an optimization technique is employed to maximize the likelihood function while determining the unknown model parameters. As the predictive model at a lower hierarchy level becomes valid, the valid model is fused into a model at a higher hierarchy level. The validation execution is then continued for the model at the higher hierarchy level. A cellular phone is used to demonstrate the hierarchical validation of predictive models presented in this paper.

And Performance

With the increase in Internet of Things (IoT) devices and network communications, but with less bandwidth growth, the resulting constraints must be overcome. Due to the network complexity and uncertainty of emergency distribution parameters in smart environments, using predetermined rules seems illogical. Reinforcement learning (RL), as a powerful machine learning approach, can handle such smart environments without a trainer or supervisor. Recently, we worked on bandwidth management in a smart environment with several fog fragments using limited shared bandwidth, where IoT devices may experience uncertain emergencies in terms of the time and sequence needed for more bandwidth for further higher-level communication. We introduced fog fragment cooperation using an RL approach under a predefined fixed threshold constraint. In this study, we promote this approach by removing the fixed level of restriction of the threshold through hierarchical reinforcement learning (HRL) and completing the cooperation qualification. At the first learning hierarchy level of the proposed approach, the best threshold level is learned over time, and the final results are used by the second learning hierarchy level, where the fog node learns the best device for helping an emergency device by temporarily lending the bandwidth. Although equipping the method to the adaptive threshold and restricting fog fragment cooperation make the learning procedure more difficult, the HRL approach increases the method’s efficiency in terms of time and performance.

The distance labeled skeleton of a two-dimensional digital object is hierarchically decomposed into loops, branches and concatenations of branches. Decomposition is obtained by using an iterated tracing-and-deleting process alternately applied to more and more internal skeleton subsets. Every skeleton subset is associated a feature, called the relevance, which is related to the spatial extension of the object region represented by that subset. The relevance is used to decide on how to perform concatenations, as well as to rank skeleton decomposition components ascribed to the same hierarchy level. The decomposition is stable under object rotation and can be used in a recognition process accomplished via graph matching.

<p><strong>Abstract</strong></p><p><strong></strong><br />One of the causes of slums in the city of Bandung is the use of untreated tent stalls. The entrepreneurial society does not have the basic culinary culture tent use, because they do not have the sensitivity to maintain it. The tent stalls were originally temporary, has turned into a permanent. Through a review of<br />ethnography, derived the concept of systematic ergonomic working in the kitchen, which is connected with the efficient use of workspace and effective use of a kitchen utensil. In the concept of Sundanese local wisdom, known as the hierarchy level of comfort based on individuals, families and communities,<br />namely 'genah-merenah-tumaninah', characterized by the use of huts 'badak heuay and jogo anjing,' home stage 'jolopong, babancong, sontong', and building 'galudra ngupuk, Jangga wirangga and towering ngapak'. This hierarchy shows the concept of stages in the culinary business Sundanese, according turnover and experience, the tavern, eating houses and restaurants.<br />The design of furniture products in the aesthetic form of huts 'badak heuay and jogo anjing', This is one of the solutions in rediscovering saung that has been lost, because of eroded stall tent of a foreign culture.</p><p> </p><p><strong>Abstrak</strong><br />Salah satu penyebab kekumuhan di Kota Bandung adalah penggunaan warung tenda yang tidak terawat. Masyarakat wirausaha kuliner tidak memiliki dasar budaya penggunaan tenda, karena mereka tidak memiliki kepekaan dalam pemeliharaan tenda. Warung tenda yang awalnya bersifat sementara, telah berubah menjadi permanen. Melalui<br />tinjauan etnografi, diperoleh adanya konsep ergonomis tentang<br />sistematika kerja di dapur, yang terhubung dengan pemakaian ruang kerja yang efisien dan penggunaan perkakas dapur yang efektif. Dalam konsep kearifan lokal Sunda, dikenal adanya hirarki kenyamanan berdasarkan tingkatan individu individu, keluarga dan masyarakat, yaitu 'genah-merenah-tumaninah', yang ditandai dengan penggunaan saung 'badak heuay dan jogo anjing', rumah panggung 'jolopong, babancong, sontong', dan gedung 'galudra ngupuk, jangga wirangga dan julang ngapak'. Hirarki ini menunjukkan adanya konsep tahapan dalam<br />bisnis kuliner Sunda, sesuai omset dan pengalamannya, yaitu kedai,</p>
