Bertambahnya penduduk dan berkembangnya kepemilikan transportasi pribadi di sebuah kota menyebabkan kemacetan semakin bertambah. Salah satu solusi dalam membenahi kemacetan yaitu pembenahan media transportasi umum seperti Kereta Rel Listrik (KRL). Perangkat teknologi dapat mendukung KRL terhindar dari berbagai masalah seperti kecelakaan akibat kesalahan teknis. Salah satu perangkat yang wajib ada pada KRL adalah sistem logging data untuk merekam segala kondisi pada kereta seperti kecepatan, jarak tempuh, suhu, tegangan, dll. Umumnya, logging data menggunakan data logger (perekam data) yang terintegrasi dengan MMC, harddisk hingga PC untuk merekam dan membaca data. Pembacaan data dilakukan oleh petugas secara lokal dari pusat kontrol. Logging data yang ada saat ini bersifat kurang praktis, efektif dan efesien. Agar sistem logging data lebih efektif, efisien dan jarak jauh, perlu dirancang sistem logging data yang dapat terintegrasi dengan server dan disimpan ke dalam media penyimpanan yang praktis. Sistem logging data dilakukan oleh perangkat berbasis mikrokontroler yang mampu membaca data analog dan data digital, merekam dan mengirimkan data rekaman ke server menggunakan jaringan 3G dengan koneksi FTP. Sistem logging data ini dapat menyimpan data secara lokal maupun terpusat, sehingga data dapat dilihat atau diakses, diambil dan dianalisis dari jarak jauh melalui web server.The population growth and the growth of private transportation ownership cause more traffic jam in a particular city. One of the solution to handle traffic jam is to fix the public transportation such as Electric Train (KRL). Technological devices can support KRL avoid various problem, such as accident caused by technical errors. A device that needs to be planted in KRL is logging data system to record all conditions of a train i.e speed, mileage, temperature, voltage, etc. In general, Logging data use data logger (data recorder) integrated with MMC, hard disk, and even PC to record and read the data. The data reading is done by an officer locally from control center. The existing logging data is less practical, efficient and effective. In order to make a more effective, more efficient and remotely logging data, it is has to be integrated with a server and saved in a simple storage media. Logging data system is done by a microcontroller based devices with abilities to read analog and digital data, record and send data to server using 3G network with FTP connection. Those logging data systems can save data locally or centrally, so the data can be read, accessed, taken and analysed remotely through a web server.

Aplikasi motor pada mesin menghasilkan kecepatan, ketepatan, dan kemudahan dalam bidang mekanika dan perindustrian. Motor yang dapat mengendalikan posisi sudut dan menghasilkan kecepatan secara otomatis adalah motor servo. Pengaturan posisi sudut motor servo dapat dilakukan melalui sebuah mikrokontroler yang diprogram dan dihubungkan ke motor servo. Pemrograman ini berfungsi untuk mengatur sudut, posisi, dan kecepatan yang sudah tetap dan tidak bisa diubah secara langsung. Pengubahan program secara tidak langsung menjadi kendala ketika sudut dan posisi motor servo akan diprogram secara berulang. Antarmuka dirancang dan akan digunakan sebagai pengendali motor servo secara langsung agar motor servo tidak diprogram secara berulang. Antarmuka dibuat menggunakan perangkat lunak Octave. Octave mengirim perintah ke motor servo melalui kabel serial yang menghubungkan PC dan mikrokontroller. Setelah itu, Octave akan mengakusisi data dari encoder untuk membandingkan antara masukan dan hasil keluaran pada motor servo. Data perbandingan akan digunakan sebagai feedback dari posisi motor servo jika sudah tepat sesuai masukan. Hasil akhir pada Tugas Akhir ini adalah perangkat lunak berupa antarmuka instrumentasi dan pengendalian motor servo berbasis Octave.Motor applications on a machine generates speed, accuracy, and ease in the field of mechanics and industrial. Motors that can control the angle position and automatically generate speed is servo motor. Setting the angle position of a servo motor can be done via a microcontroller that is programmed and connected to a servo motor. Programming serves to adjust the angle, position, and velocity that have been fixed and can not be modified directly. However, changing the program indirectly becomes a problem when the angle and position of the servo motor will be programmed repeatedly. The interface is designed and to be used as a directly servo motors controller so that the servo motor is not programmed repeatedly. The interface is made using the Octave software. Octave send commands to the servo motor via a serial cable which is connecting the PC and microcontroller. Then, Octave will acquire data from the encoder to compare between the input and output on the servo motor. Comparison data will be used as a feedback of servo motor position whether it is correct according to the inputs. The end result in this thesis is a software in the form of instrumentation interface and servo motor controller which is Octave-based.

Published: July 2024

Aims: To do a comparative study of the anti-elastase activity of the extract, extract-loaded gelatin nanoparticles, and serum gels of Indonesian Bilberry leaves.
Methods: Extraction of the leaves used the maceration method with 70% ethanol at a pH of 2 and dried using a rotavapor and an oven. The dry extracts were phytochemical screened and tested for specific and non-specific parameters. The synthesis of gelatin nanoparticles used the desolvation method with polymer gelatin and cross-linker glutaraldehyde, and then they were characterized. The extracts and the gelatin nanoparticles were formulated into serum gels and evaluated for physical, chemical, and anti-elastase activity at 40°C for six weeks. The extracts, nanoparticles, and formulations were assayed for anti-elastase activity at 410 nm.
Results: The extracts met standards, while the nanoparticles showed particle sizes of 174.7 nm, polydispersity index of 0.34, zeta potential of 2.82 mV, entrapment efficiency of 38.6%, aldimine on FTIR, and shape of stacked nanoparticles. The anti-elastase activity of the extract was 49.37 ppm, while the nanoparticles were 72.92 ppm, respectively. In addition, the serum gels of F1 were 117.92 ppm, and F2 were 142.92 ppm. F1 and F2 were stable during storage. It is still possible to enhance the activity of the serum gels, such as by increasing the addition of actives.
Conclusion: The extract, gelatin nanoparticles, and serum gels of F1 and F2 have anti-elastase activity in the potent category for the extract and nanoparticles, while moderate category for F1 and F2. The serum gels are physicochemically stable during storage.
Ambient‐temperature fusible filter: a preliminary experiment and a proposal for a filtration process
Authors: Teduka Masahiro , Nishioka Takeshi 
Published: November 2013

SignificanceA new filtration apparatus is proposed using a fusible filter medium (FF). The advantages of FF are (1) materials captured by the filter can be recovered by melting the filter and subsequent gravity separation, (2) the filter medium can be recycled, and (3) the latent heat of solidification removed to produce FF is significantly lower than that of vaporization. The filtration can be further simplified and made more cost‐efficient using an “ambient‐temperature” fusible filter (ATFF). © 2013 American Institute of Chemical Engineers AIChE J, 60: 22–26, 2014
Technical Note: Anatomic identification of isolated modern human molars: Testing procrustes aligned outlines as a standardization procedure for elliptic fourier analysis
Authors: Corny Julien , Détroit Florent 
Published: November 2013

ABSTRACTThe determination of the precise position of permanent first and second modern human molars, following standard tooth identification criteria, is often difficult because of their morphological similarities. Here, we proposed to evaluate the suitability of two‐dimensional crown contour shape analysis in achieving this objective. The method was tested separately on 180 first and second maxillary molars (UM) and 180 first and second mandibular molars (LM) securely identified (in anatomical position in their sockets). Generalized Procrustes superimposition is used to normalize the outlines prior to applying elliptic Fourier analyses (“EFAproc” method). Reliability and effectiveness of this morphometric procedure was evaluated by comparing the results obtained for the same dataset with four other morphometric methods of contour analysis. Cross‐validated (“leave one individual out”) percentages of misclassification yielded by linear discriminant analyses were used for determining the anatomic position of modern human molars. The percentages of misclassifications obtained from every method of contour analysis were low (1.67% to 3.33% for the UM, 5.56% to 6.67% for the LM) indicating the high suitability of crown contour analyses in correctly identifying molars. A reliable protocol, based on predictive linear discriminant analyses, was then proposed for identification of isolated molars. In addition, our results confirmed that the EFAproc method is suitable for normalizing outlines prior to undertaking elliptic Fourier analyses, especially in the case of nearly circular outlines: it obtained better classification than the classic method of normalization of Fourier descriptors for UM and provided also some advantages over the three landmarks‐based methods tested here.

Key Clinical MessageThe scenario of a renal transplant recipient who is diagnosed with HIV infection in the late post transplant period is very uncommon. The viral infection effect on immunologic stability, regulatory cells, and allogeneic response during immune quiescence and graft acceptance provides a fertile ground in organ transplantation research and translational immunology.
“We've Got Creative Differences”: The Effects of Task Conflict and Participative Safety on Team Creative Performance
Authors: Fairchild Joshua , Hunter Samuel T. 
Published: November 2013

AbstractAlthough both participative safety and team task conflict are widely thought to be related to team creative performance, the nature of this relationship is still not well understood, and prior studies have frequently yielded conflicting results. This study examines the ambiguity in the extant literature and proposes that both constructs must exist in tandem. Through a study of 55 design teams, we have identified a significant interaction between task conflict and participative safety. Results suggest that both participative safety and task conflict must exist in tandem to spur team creativity, and that team creative performance must be examined at the facet level, instead of simply as a single construct. In addition, supplemental analyses suggest that teams low on participative safety and task conflict are likely able to generate more original solutions for creative tasks due to the presence of an independent, disagreeable creative member. Implications for future research and practice are further discussed.
Fabrication of mesa structural n‐type nanocrystalline‐FeSi2/p‐type Si heterojunction photodiodes by liftoff technique combined with photolithography

Published: November 2013

AbstractMesa structural n‐type nanocrystalline (NC) FeSi2/p‐type Si heterojunctions were fabricated by a liftoff technique combined with photolithography in order to improve the diode performance, particularly to reduce the parasitic capacitance. Their current‐voltage characteristics were experimentally studied in the dark and under illumination using a 1.31 μm laser at room temperature. Their junction capacitance density and leakage current density were evidently reduced as compared with those of the normal structural diodes. The mesa diode exhibits a good rectifying action with a rectification ratio of approximately three orders of magnitude at bias voltages of ±1 V. The photodetection was clearly observed owing to the suppression in the dark current. The estimated detectivity is 2.0 × 109 cm√Hz/W at zero bias, which is an order of magnitude larger than that of the normal structural diodes. This should be because the formation of interface states is reduced accompanied by the interface area reduction. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Electroluminescence properties of p‐Si/β ‐FeSi2 NCs/…/n‐Si mesa diodes with embedded multilayers of β ‐FeSi2 nanocrystallites

Published: November 2013

AbstractLight‐emitting silicon diode structures with embedded β ‐FeSi2 nanocrystallites have been fabricated using solid phase epitaxy and a combination of reactive deposition and solid phase epitaxy. Electroluminescence (EL) of the structures is studied over various temperatures and current densities under forward and reverse biases. We can state that β ‐FeSi2 NCs formed by the combined RDE+SPE method results in the formation of high density of dislocations and point defects. In contrast, defect‐free structures with β ‐FeSi2 NCs formed by SPE demonstrate intense EL (η = 1.2×10‐5%) in the wavelength range 1.4–1.6 µm even at room temperature. EL intensity dependence on the number of layers with embedded β ‐FeSi2 NCs is almost linear for the heterostructures formed on Si(100) and sublinear for the heterostructures formed on Si(111) substrate. The increase of the initial Fe layer thickness leads to the electroluminescence quenching. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractOptimization of growth parameters has permitted to create monolithic nanocomposites with buried nanocrystallites (NCs) of iron and chromium disilicides, polycrystalline nanocomposites with buried Mg2Si NCs and epitaxial MnSi1.74 nanoislands on Si(111) substrate. Grown quasi‐zero dimensional heterostructures with multilayers of β‐FeSi2 NCs atop silicon p‐n junction have demonstrated the range expansion of photoelectrical sensitivity up to 1.8 µm and strong room temperature electroluminescence at 1.2 – 1.6 µm. A new approach to the selective doping of embeddded nanocrystallites inside silicon matrix has been developed on the base of the successive formation of ordered superstructures of metals (Ag, Sb) together with silicide island formation. Nanocomposite layers with n‐ and p‐type conductivity and huge Seebeck coefficient (550‐750 µV/K) in the Si‐p/β‐FeSi2 NCs/Si‐p and Si/Mg2Si NCs/Si‐p and Si/Mg2Si NCs/Si‐n nanocomposites have been created and tested.

TCP‐polite rate control based on cooperative measurement
Authors: Wang Wen‐Yong , Huang Li‐Sheng , Li Chang‐Chun , Wang Xin 
Published: November 2013

AbstractBased on the cooperative measurement of new congestion metric instead of drop ratio and round‐trip time, a new cooperative transmission control mechanism, called TCP‐polite rate control (TPRC), is proposed. In this scheme, the congestion metric of network is obtained with cooperative measurement and feeds back to rate‐based pacing mechanism, thus keeping the transmission rate at the lower bound of available bandwidth. Simulation results show that TPRC scheme outperforms TCP and TCP‐friendly rate control protocol in terms of fast‐start, efficiency, and fairness. Copyright © 2013 John Wiley & Sons, Ltd.
Protecting mobile agents communications in pervasive networks with a trusted distributed mediator for ID‐based RSA
Authors: Maccari L. , Fantacci R. , Pecorella T. , Ghettini G. , Chiti F. 
Published: November 2013

ABSTRACTThis paper proposes a new method of data authentication and encryption for distributed networks supporting mobile software agents. Software agents are a valuable instrument in wireless distributed monitoring networks, because they can be used to concentrate monitoring efforts in certain areas where an event is taking place. In this way, events can be tracked in a dynamic and efficient way. Mobile agents have to send messages to each other in order to coordinate their actions, and those messages need to be secured by crypto credentials. However, when agents are moved over wireless networks, how can credentials be protected from sniffing by an attacker, besides layer II encryption? Moreover, if a rogue agent is injected in the network, is it possible to limit the damages it can produce? The proposed approach bridges mediated RSA with the trusted platform modules, in order to provide an efficient and secure communication between agents. The communication is secured using indeed Identity based cryptography, while maintaing the compatibility with standard RSA and eliminating the mediator introduced by mediated RSA. We will show that this approach is convenient in terms of traffic overhead, perfectly applicable to existing trusted platform modules specifications and able to limit damages that both external and internal attackers can produce to the network.

Privacy‐assured substructure similarity query over encrypted graph‐structured data in cloud
Authors: Zhang Yingguang , Su Sen , Wang Yulong , Chen Weifeng , Yang Fangchun 
Published: November 2013

ABSTRACTIn recent years, large amounts of graph‐structured data have been outsourced to the commercial public cloud. It is a crucial requirement to enable substructure similarity query for effective data retrieval. However, for protecting data privacy, sensitive data have to be encrypted before outsourcing, which impedes the traditional similarity query schemes from being supported in cloud. Most existing works on encrypted cloud data retrieval pay little attention to this problem. Additionally, considering the huge amounts of encrypted data graphs, the complicated similarity computation and privacy requirements, it is particularly challenging to solve this problem effectively. In this paper, for the first time, we investigate the problem of privacy‐assured substructure similarity query over encrypted graph‐structured data in cloud computing. Our solution explores a secure framework and a series of secure algorithms to efficiently perform the substructure similarity query without privacy breaches. The proposed solution first builds a secure feature‐graph index to represent the feature‐related information about each encrypted data graph based on privacy homomorphism and obscuration methods and then calculates the similarity between the query graph and each data graph by the difference of feature frequency in a privacy‐preserving manner. Thorough analysis is given to investigate effectiveness and privacy guarantees, and the experiments with real dataset further demonstrate the validity and efficiency of the proposed solution.
