"Passive methods as a solution for improving indoor environments includes both software simulations and laboratory and field studies. Through these, the main parameters that characterize the behavior of internal coverings are defined. Furthermore, a new procedure is explained in depth which can be used to identify the real expected effects of permeable coverings such as energy conservation and local thermal comfort as well as their working periods in controlling indoor environments. This theoretical base is built on by considering future research work including patents and construction indications which will improve indoor environmental conditions with evidence from real data.

"Learning in non-stationary environments : methods and applications offers a wide-ranging, comprehensive review of recent developments and important methodologies in the field. The coverage focuses on dynamic learning in unsupervised problems, dynamic learning in supervised classification and dynamic learning in supervised regression problems. A later section is dedicated to applications in which dynamic learning methods serve as keystones for achieving models with high accuracy. Rather than rely on a mathematical theorem/proof style, the editors highlight numerous figures, tables, examples and applications, together with their explanations."

"In this book, which focuses on the use of iterative methods for solving large sparse systems of linear equations, templates are introduced to meet the needs of both the traditional user and the high-performance specialist. Templates, a description of a general algorithm rather than the executable object or source code more commonly found in a conventional software library, offer whatever degree of customization the user may desire. Templates offer three distinct advantages: they are general and reusable; they are not language specific; and they exploit the expertise of both the numerical analyst, who creates a template reflecting in-depth knowledge of a specific numerical technique, and the computational scientist, who then provides "value-added" capability to the general template description, customizing it for specific needs. For each template that is presented, the authors provide: a mathematical description of the flow of algorithm; discussion of convergence and stopping criteria to use in the iteration; suggestions for applying a method to special matrix types; advice for tuning the template; tips on parallel implementations; and hints as to when and why a method is useful."

"Selection of an automated inspection device for an explicit industrial application is one of the most challenging problems in the current manufacturing environment. It has become more and more complicated due to increasing complexity, advanced features and facilities that are endlessly being integrated into the devices by different manufacturers. Selection of inspection devices plays a significant role in a manufacturing system for cost effectiveness and improved productivity. This paper focuses on the application of a very popular Multi-Criteria Decision-Making (MCDM) tool, i.e. ELimination and Et Choice Translating REality (ELECTRE) for solving an automated inspection device selection problem in a discrete manufacturing environment. Using a sample case study from the published literature, this paper attempts to show how different variants of the ELECTRE method, namely ELECTRE II, IS, III, IV and TRI can be suitably applied in choosing the most efficient alternative that accounts for both the decision maker’s intervention and other technical elements. Using different ELECTRE methods, a list of all the possible choices from the best to the worst suitable devices is obtained while taking into account different selection attributes. The ranking performance of these methods is also compared with that of the past researchers."

"Masalah pokok penggunaan fingerprinting Receive Signal Strength (RSS) pada indoor localization adalah pengaruh lingkungan terhadap hasil pengukuran RSS, menyikapi variabilitas nilai RSS dan akurasi penentuan posisi. Penelitian ini mengkombinasikan penggunaan keunggulan teknologi LoRa dengan metode deep learning yang menggunakan semua variasi hasil pengukuran nilai RSS di setiap posisi sebagai fitur alami dari kondisi dalam ruangan sebagai fingerprinting untuk melatih model pada deep learning. Teknik ini diberi nama DeepFi-LoRaIn, yang menggambarkan teknik untuk menggunakan data fingerprinting dari RSS perangkat LoRa pada indoor localization menggunakan metode deep learning. Penelitian ini dilakukan tidak hanya sebatas pengujian dan pembuktian metode menggunakan pendekatan testbed dan simulasi, namun berlanjut hingga tahapan implementasi menggunakan RSS fingerprinting dari hasil pengukuran sebenarnya. Skenario pengujian yang digunakan untuk mengevaluasi model adalah skenario tanpa gangguan dan skenario dengan memberikan gangguan. Skenario gangguan dilakukan dengan cara memberikan gangguan pada nilai RSS yang diterima di beberapa anchor node. Pada pengujian menggunakan dataset simulasi diperoleh hasil prediksi posisi dengan nilai akurasi 100% untuk skenario tanpa gangguan. Sedangkan pada skenario dengan gangguan diperoleh hasil akurasi prediksi posisi sebesar 86,66%. Hasil pengujian prediksi posisi menggunakan data pengukuran langsung diperoleh nilai akurasi sebesar 96,22%, untuk skenario tanpa gangguan dan 92,45%. untuk skenario pengujian dengan gangguan. Berdasarkan hasil penelitian menggunakan data simulasi dan data pengukuran sebenarnya pada implementasi, diperoleh kesimpulan bahwa, penggunaan Teknik DeepFi-LoRaIn mampu mengatasi permasalahan pada variabilitas nilai RSS didalam ruangan dan mampu menjaga akurasi prediksi posisi jika terjadi gangguan yang disebabkan oleh perubahan kondisi lingkungan.

The main problem using fingerprinting Receive Signal Strength (RSS) in indoor localization is the influence of the environment on the results of RSS measurements, addressing the variability of RSS values and positioning accuracy. This study combines the use of the advantages of LoRa technology with a deep learning method that uses all variations of the RSS value measurement results in each position as a natural feature of indoor conditions as fingerprinting to train models in deep learning. This technique is named DeepFi-LoRaIn, which describes a technique for using RSS fingerprinting data from LoRa devices in indoor localization using deep learning methods. This research is not only limited to testing and proving the method using a testbed and simulation approach, but continues to the implementation stage using RSS fingerprinting from the actual measurement results. The test scenarios used to evaluate the model are the without interference scenario and the with interference scenario. The inteference scenario is done by giving disturbance to the RSS value received at several anchor nodes. In testing using a simulation dataset, position prediction results are obtained with an accuracy value of 100% for without interference scenarios. Meanwhile, in the scenario with interference, the accuracy of position prediction is 86.66%. The results of the position prediction test using direct measurement data obtained an accuracy value of 96.22%, for the scenario without interference and 92.45%. Based on the results of the study using simulation data and actual measurement data in the implementation, it was concluded that the use of the DeepFi-LoRaIn technique was able to overcome the problem of the variability of the RSS value in the room and was able to maintain the accuracy of position prediction in case of disturbances caused by changes in environmental conditions."
