Charged Rotating BTZ Black Hole and Thermodynamic Behavior of Field Equations at its Horizon

In this paper, we study different cases of the charged rotating BTZ black hole with reference to their horizons. For the existence of these cases conditions on mass, charge and angular momentum of the black hole are obtained. It is also shown that the Einstein field equations for the charged rotating BTZ black hole at the horizon can be expressed as first law of thermodynamics, $dE=TdS+\Omega dJ+\Phi dq+P_{r}dA$.Comment: 12 pages, 3 figure

Tinjauan Yuridis Tentang Pembuktian Di Pengadilan Mengenai Tindak Pidana Mata Uang Palsu (Studi Kasus Putusan Pengadilan Negeri Palu No. 113/pi.b/2010/pn.pi)

Pembuktian di pengadilan mengenai tindak pidana mata uang palsu (studi kasus putusan pengadilan negeri Palu no. 113/Pi.B/2010/PN.PI), dengan identifikasi masalah bagaimana upaya penuntut umum membuktikan di pengadilan terhadap perkara tindak pidana pemalsuan mata uang palsu dan bagaimanakah pertimbangan hakim dalam menjatuhkan putusan terhadap perkara tindak pidana pemalsuan mata uang. Diketahui upaya penuntut umum membuktikan di pengadilan terhadap perkara tindak pidana pemalsuan mata uang menyatakan terdakwa telah terbukti secara sah dan meyakinkan telah melakukan pidana yang didakwakan yaitu tindak pidana pemalsuan mata uang. Adapun yang menjadi dasar pertimbangan hakim dalam menjatuhkan putusan terhadap perkara tindak pidana pemalsuan mata uang adalah berdasarkan alat-alat bukti yakni keterangan saksi dan dan keterangan terdakwa disertai alat bukti yang diajukan dalam surat dakwaan oleh penuntut umum serta fakta-fakta lengkap didepan persidangan

Exhaustive Search-based Model for Hybrid Sensor Network

A new model for a cluster of hybrid sensors network with multi sub-clusters is proposed. The model is in particular relevant to the early warning system in a large scale monitoring system in, for example, a nuclear power plant. It mainly addresses to a safety critical system which requires real-time processes with high accuracy. The mathematical model is based on the extended conventional search algorithm with certain interactions among the nearest neighborhood of sensors. It is argued that the model could realize a highly accurate decision support system with less number of parameters. A case of one dimensional interaction function is discussed, and a simple algorithm for the model is also given.Comment: 6 pages, Proceeding of the International Conference on Intelligent & Advanced Systems 2012 pp. 557-56

On Modeling Geometric Joint Sink Mobility with Delay-Tolerant Cluster-less Wireless Sensor Networks

Moving Sink (MS) in Wireless Sensor Networks (WSNs) has appeared as a blessing because it collects data directly from the nodes where the concept of relay nodes is becomes obsolete. There are, however, a few challenges to be taken care of, like data delay tolerance and trajectory of MS which is NP-hard. In our proposed scheme, we divide the square field in small squares. Middle point of the partitioned area is the sojourn location of the sink, and nodes around MS are in its transmission range, which send directly the sensed data in a delay-tolerant fashion. Two sinks are moving simultaneously; one inside and having four sojourn locations and other in outer trajectory having twelve sojourn locations. Introduction of the joint mobility enhances network life and ultimately throughput. As the MS comes under the NP-hard problem, we convert it into a geometric problem and define it as, Geometric Sink Movement (GSM). A set of linear programming equations has also been given in support of GSM which prolongs network life time

Optical Photometry and Spectroscopy of the Suspected Cool Algol AV Delphini: Determination of the Physical Properties

We present new spectroscopic and BVRI photometric observations of the double-lined eclipsing binary AV Del ( period = 3:85 days) conducted over six observing seasons. A detailed radial velocity and light-curve analysis of the optical data shows the system to be most likely semidetached, with the less massive and cooler star filling its Roche lobe. The system is probably a member of the rare class of ‘‘cool Algol’’ systems, which are distinguished from the ‘‘classical’’ Algol systems in that the mass-gaining component is also a late-type star rather than a B- or A-type star. By combining the spectroscopic and photometric analyses, we derive accurate absolute masses for the components of M1 = 1.453 + 0.028 M and M2 = 0.705 + 0.014 M and radii of R1 = 2.632 + 0.030 R and R2 = 4.233 + 0.060 R, as well as effective temperatures of 6000 + 200 and 4275 + 150 K for the primary and secondary, respectively. There are no obvious signs of activity (spottedness) in the optical light curve of the binary
