ACCURATE INDOOR POSITION ESTIMATION TECHNIQUE USING FINGERPRINTING AND LATERATION-BASED APPROACH IN BLUETOOTH TECHNOLOGY
No full textThe first part consists of experimental analysis of Bluetooth signal parameters in order to select the best suitable parameter for position estimation.
This part also presents a comprehensive experimental analysis to observe the relationship between signal parameters and distance, so that the main source of
distance estimation error can be identified. After selecting the best suitable parameter for position estimation, the next issue is to address the distance estimation error and identify its causes. This is handled in the second part of the thesis, which addresses
the problem of communication holes. It presents an extended Gradient RSS predictor and filter, which is used to predict and filter RSS measurements in communication holes. The prediction and filtering process is based on the selected signal parameter based on our experimental observations. The refined output measurements are then given to the position estimation algorithm, which is handled in the third part of thesis. The third part of this thesis presents a new filter based hybrid position estimation
technique, which integrates the features of fingerprinting and lateration approach. The novel approach used in the proposed hybrid approach is the use of Euclidian distance
formula for distance estimation instead of propagation model. Simulation and experimental results validate the performance of proposed hybrid technique and
improve the accuracy up to 53.64 % and 25.58 % compared to Lateration and fingerprinting approach, respectively. In summary, this thesis presents a complete framework for indoor position estimation using Bluetooth networks
Multilevel Sparse Kernel-Based Interpolation
No full textRadial basis functions (RBFs) have been successfully applied for the last four decades for fitting scattered data in Rd, due to their simple implementation for any d. However, RBF interpolation faces the challenge of keeping a balance between convergence performance and numerical stability. Moreover, to ensure good convergence rates in high dimensions, one has to deal with the difficulty of exponential growth of the degrees of freedom with respect to the dimension d of the interpolation problem. This makes the application of RBFs limited to few thousands of data sites and/or low dimensions in practice.
In this work, we propose a hierarchical multilevel scheme, termed sparse kernel-based interpolation (SKI) algorithm, for the solution of interpolation problem in high dimensions. The new scheme uses direction-wise multilevel decomposition of structured or mildly unstructured interpolation data sites in conjunction with the application of kernel-based interpolants with different scaling in each direction. The new SKI algorithm can be viewed as an extension of the idea of sparse grids/hyperbolic cross to kernel-based functions.
To achieve accelerated convergence, we propose a multilevel version of the SKI algorithm.
The SKI and multilevel SKI (MLSKI) algorithms admit good reproduction properties: they are numerically stable and efficient for the reconstruction of large data in Rd, for d = 2, 3, 4, with several thousand data. SKI is generally superior over classical RBF methods in terms of complexity, run time, and convergence at least for large data sets. The MLSKI algorithm accelerates the convergence of SKI and has also generally faster convergence than the classical multilevel RBF scheme

Evaluation method, task outcomes and group structure as counteracting strategies of social loafing in manufacturing industries of Pakistan
No full textThe study examines task evaluation techniques; task outcomes and group structure composition in counteracting social loafing. The approach espoused in this paper is to assess the conventional literature that provides strong support for existence of social loafing phenomenon in groups and to predict counteracting from aforementioned variables.Based on latest literature innovative ways for combating social loafing are discussed. Results provide conclusive support that enhancing evaluation method, task outcomes and group structure were associated with reduced occurrence of social loafing. At group level increased conjunctive task and reward interdependence, heterogeneity and peer evaluation increase social loafing while increase in task meaningfulness, content, intensity, homogeneity, disjunctive and self evaluation reduce social loafing. The paper provides practical implications that enhancing task evaluation techniques, outcomes and group structure reduce social loafing and ultimately increase organizational performance.The study is unique as no one has focused the phenomenon of social loafing in Pakistan, thus it also contribute knowledge to literature
Juridical Overview of the Implementation of Marriage and Divorce for Members of the Army (TNI Ad) in Indonesia (Case Study of Denma Kodam I/Bb)
No full text50 HalamanSalah satu peristiwa hukum penting dalam kehidupan manusia adalah perkawinan.
Menurut Undang-Undang No. 16 Tahun 2019 Perubahan Atas Undang-Undang
Nomor 1 Tahun 1974 tentang Perkawinan, Setiap warga negara berhak untuk
melangsungkan perkawinan termasuk juga bagi anggota TNI, dalam perkawinan
anggota TNI AD selain tunduk undang-undang perkawinan juga terdapat
peraturan internal TNI, terkait dengan hal tersebut maka dalam penelitia ini
penulis akan mengkaji masalah tetang prosedur perkawinan TNI AD secara
umum, proses perceraian jika istri/suami yang beragama Islam yang menggugat
cerai. Metode penelitian yang digunakan dalam penelitian ini adalah yuridis
normatif, teknik pengumpulan data yaitu dengan penelitian kepustakaan dan
wawancara, suber data terdiri dari data primer, sekunder dan tersier, dari hasil
penelitian ini, penulis dapat menarik sutu kesimpulan bahwa proses perkawinan
TNI AD berbeda dengan masyarakat sipil pada umumnya, perkawinan anggota
TNI AD terlebih dahulu harus mendapat ijin dari pejabat internal TNI, selain
tunduk pada undang-undang perkawinan juga tunduk pada Peraturan Menteri
Pertahanan Nomor 23 Tahun 2008 Tentang Perkawinana, Perceraian, Dan Rujuk
Pegawai Di Lingkungan Departemen Pertahanan Keputusan Kasad Nomor
Kep/496/VII/2015 Tanggal 27 Juli 2015 Petunjuk Teknis Tentang Tata Cara
Perkawinan, Perceraian, Dan Rujuk Bagi Prajurit TNI AD, prosedur perceraian
jika istri/suami TNI AD yang beragama Islam yang menggugat cerai terlebih
dahulu mendapat persetujuan dari kesatuan harus memuat secara jelas alasanalasan
perceraian diajukan kepada Pejabat yang berwenang memberikan izin
perceraian melalui saluran hierarki setelah dibubuhi pendapat dari pejabat agama
yang bersangkutan (Pejabat yang berwenang memberi izin nikah/cerai) sebagai
saran Bagi calon istri atau suami yang hendak menikah dengan prajurit TNI AD
sebaiknya sudah mengetahui bahwa banyak persyaratan yang harus dilalai untuk
itu jangan menyerah dan merasa keberatan. Terkait dengan percaeraian dalam
kesatuan TNI AD penulis juga menyarankan agar setiap anggota menaati
peraturan internal kesatuan dalam hal akan melaksanakan perceraia karena penulis
menemukan beberapa kasus perceraian yang tidak sesuai dengan prosedur dalam
kesatuan TNI AD melaksanakan perceraian tanpa ijin atasan. One of the important legal events in human life is marriage. According to Law no.
16 of 2019 Amendments to Law Number 1 of 1974 concerning Marriage, Every
citizen has the right to marry including members of the TNI, in the marriage of
members of the Indonesian Army, apart from being subject to the marriage law,
there are also internal TNI regulations, related to this matter. In this study, the
author will examine the problem of the TNI AD marriage procedure in general,
the divorce process if the wife / husband is a Muslim who is suing for divorce.
The research method used in this study is normative juridical, data collection
techniques are library research and interviews, data sources consist of primary,
secondary and tertiary data, from the results of this study, the author can draw a
conclusion that the TNI AD marriage process is different from the community. In
general, the marriage of members of the TNI AD must first obtain permission
from internal TNI officials, in addition to being subject to the marriage law, it is
also subject to Regulation of the Minister of Defense Number 23 of 2008
concerning Marriage, Divorce, and Referral of Employees within the Department
of Defense Decree of Kasad No. Kep/496/VII/2015 Dated 27 July 2015 Technical
Instructions on Marriage, Divorce, and Referral Procedures for Indonesian Army
Soldiers, the divorce procedure if the wife/husband of the Indonesian Army who
is a Muslim who is suing for divorce first obtains approval from the Unity, must
include clear reasons for divorce submitted to the official t who is authorized to
give divorce permits through hierarchical channels after being affixed with the
opinion of the relevant religious official (officials authorized to give
marriage/divorce permits) as a suggestion For a prospective wife or husband who
wants to marry an Army soldier, it is better to know that there are many
requirements that must be neglected for that do not give up and feel objected.
Regarding divorce within the Indonesian Army, the author also recommends that
each member obey the internal regulations of the unit in terms of going to divorce
because the author finds several divorce cases that are not in accordance with the
procedures in the TNI AD unit carrying out divorce without the superior's
permission
