Conditions for State and Control Constraint Activation in Coordination of Connected and Automated Vehicles

Connected and automated vehicles (CAVs) provide the most intriguing opportunity to reduce pollution, energy consumption, and travel delays. In earlier work, we addressed the optimal coordination of CAVs using Hamiltonian analysis. In this paper, we investigate the nature of the unconstrained problem and provide conditions under which the state and control constraints become active. We derive a closed-form analytical solution of the constrained optimization problem and evaluate the solution using numerical simulation

Concurrent Optimization of Vehicle Dynamics and Powertrain Operation Using Connectivity and Automation

Connected and automated vehicles (CAVs) provide the most intriguing opportunity to reduce energy consumption and travel delays. In this paper, we propose a two-level control architecture for CAVs to optimize (1) the vehicle's speed profile, aimed at minimizing stop-and-go driving, and (2) the powertrain efficiency of the vehicle for the optimal speed profile derived in (1). The proposed hierarchical control framework can be implemented onboard the vehicle in real time with minimal computational effort. We evaluate the effectiveness of the efficiency of the proposed architecture through simulation in Mcity using a 100% penetration rate of CAVs. The results show that the proposed approach yields significant benefits in terms of energy efficiency.Comment: Updating and replacing the old version of arXiv:1911.03475 with the finalized manuscrip

Penyuluhan Kehutanan Partisipatif

Participative extension is an extension model that involves farmers in the whole process of decision making. Extension officers have several functions such as to strengthen the ability and the potency of the farmers, to improve their agricultural management, and to utilize the forest by involving them at the beginning stage of the study (from data collection, analysis, identification, planning, organization, implementation, monitoring, and evaluation, until the reporting activity). To increase the outcome, we need to held the course for the forestry extension officers and the farmers as target groups regularly.

Manusia dalam Berbagai Perspektif

Manusia merupakan makhluk yang tidak terwujud dengan sendirinya melainkan keberadaannya ada yang menciptakan. Menurut pendapat jumhur dan hampir seluruh mufassir menyebut Adam sebagai makhluk/manusia pertama yang kemudian diikuti penciptaan istrinya (Hawa) yang kemudian berkembang biak memenuhi bumi. Al-Qur\u27an tidak menjelaskan secara detail dan terperinci setidaknya apa yang ada dan disinggung dalam al-Qur\u27an tentang wujud fisik manusia adalah kebenaran dari Tuhan yang terbukti secara ilmiah. Adapun memahami manusia secara spritual (jiwa, nafs, roh) bukanlah hal yang sederhana, bahkan amat rumit. Hingga sekarang belum ada yang bisa membuktikannya secara ilmiah selain dari gejala-gejalanya saja. Informasi tentang jiwa dan roh tersebut di dalam al-Qur\u27an dijelaskan dalam kadar yang berbeda. Setidaknya ada 3 hal yang menyebabkan ruh dan jiwa berbeda, perbedaan pertama, pada substansinya. Jenis dan ruh berbeda dari segi kualitas dzatnya : jiwa digambarkan sebagai dzat yang bisa berubah-ubah kualitas, naik turun, jelek dan baik, kotor dan bersih, dan seterusnya. Sedangkan ruh digambarkan sebagai dzat yang selalu baik dan suci, berkualitas tinggi. Perbedaan kedua antara jiwa dan ruh adalah fungsinya. Jiwa digambarkan sebagai “sosok” yang bertanggung jawab atas segala dzat yang selalu baik dan berkualitas tinggi, sebaliknya hawa nafsu adalah dzat yang berkualitas rendah dan selalu mengajak kepada keburukan, sedangkan jiwa adalah dzat yang bisa memilih kebaikan dan keburukan tersebut. Maka jiwa harus bertanggung jawab terhadap pilihannya. Dan perbedaan ketiga, perbedaan itu ada pada sifatnya, dimana jiwa merasakan kesedihan, kekecewaan, kegembiraan, kebahagiaan, ketentraman, ketenangan dan kedamaian. Sedangkan ruh bersifat stabil dalam kebaikan tanpa mengenal perbandingan. Ruh adalah kutub positif dari sifat kemanusiaan sebagai lawan dari sifat setan yang negati

Active User Authentication for Smartphones: A Challenge Data Set and Benchmark Results

In this paper, automated user verification techniques for smartphones are investigated. A unique non-commercial dataset, the University of Maryland Active Authentication Dataset 02 (UMDAA-02) for multi-modal user authentication research is introduced. This paper focuses on three sensors - front camera, touch sensor and location service while providing a general description for other modalities. Benchmark results for face detection, face verification, touch-based user identification and location-based next-place prediction are presented, which indicate that more robust methods fine-tuned to the mobile platform are needed to achieve satisfactory verification accuracy. The dataset will be made available to the research community for promoting additional research.Comment: 8 pages, 12 figures, 6 tables. Best poster award at BTAS 201

Hermeneutika Sufistik Al-Ghazâlî Dalam Mishkât Al-Anwâr

This paper attempts to identify the character and form of interpretation al-Ghazâlî against the Koran, especially when interpreting the verses of the Koran in one of his work, Mishkât al-Anwâr. When viewed from the authority of the text and the author (interpreter), the style of the interpretation of al-Ghazâlî appears to have similarities with the concept of philosophical hermeneutics of Gadamer. But it is not so, there are significant differences between the two. If Gadamer's model interpretation is called Philosophical Hermeneutics, then the interpretation of al-Ghazâlî style more to the Sufi Hermeneutics. In the end, this paper concluded that al-Ghazâlî's Sufi Hermeneutics rests on two elements are simples but not smalls; rationality (al-ma‘qûl) led by entities in it like the soul (al-nafs), soul (al-rûh), heart (al-qalb), intellect (al-‘aql), and textuality (al-manqûl) the object stratified into five aspects, namely the existence of essential (wujûd dhâtî), the existence of sensory (wujûd hissî), the existence of imaginative (wujûd khayyâlî), the existence of a rational (wujûd ‘aqlî), the existence of analogical (wujûd shibhî)

Extracting Low-Lying Lambda Resonances Using Correlation Matrix Techniques

The lowest-lying negative-parity state of the Lambda is investigated in (2+1)-flavour full-QCD on the PACS-CS configurations made available through the ILDG. We show that a variational analysis using multiple source and sink smearings can extract a state lying lower than that obtained by using a standard fixed smeared source and sink operator alone.Comment: 3 pages, 1 figure, submitted to the proceedings of T(R)OPICAL QCD II, Cairns, Australia, 201

Searching for low-lying multi-particle thresholds in lattice spectroscopy

We explore the Euclidean-time tails of odd-parity nucleon correlation functions in a search for the S-wave pion-nucleon scattering-state threshold contribution. The analysis is performed using 2+1 flavor 32^3 x 64 PACS-CS gauge configurations available via the ILDG. Correlation matrices composed with various levels of fermion source/sink smearing are used to project low-lying states. The consideration of 25,600 fermion propagators reveals the presence of more than one state in what would normally be regarded as an eigenstate-projected correlation function. This observation is in accord with the scenario where the eigenstates contain a strong mixing of single and multi-particle states but only the single particle component has a strong coupling to the interpolating field. Employing a two-exponential fit to the eigenvector-projected correlation function, we are able to confirm the presence of two eigenstates. The lower-lying eigenstate is consistent with a N-pi scattering threshold and has a relatively small coupling to the three-quark interpolating field. We discuss the impact of this small scattering-state contamination in the eigenvector projected correlation function on previous results presented in the literature.Comment: 8 pages, 4 figures.
