Energy Loss of a Heavy Particle near 3D Charged Rotating Hairy Black Hole

In this paper we consider charged rotating black hole in 3 dimensions with an scalar charge and discuss about energy loss of heavy particle moving near the black hole horizon. We also study quasi-normal modes and find dispersion relations. We find that the effect of scalar charge and electric charge is increasing energy loss.Comment: Accepted for publication in EPJC. arXiv admin note: text overlap with arXiv:1205.4254 by other author

Art in the Age of Networks - Networks as a Way of Thinking

The theme-based and material-based units (with lessons and lesson sequences) propose a curriculum for one academic semester in an undergraduate visual arts school (for sophomore, 2nd year, or junior, 3rd year students). However the lessons could be modified and tailored to any age group developmentally. This curricular framework aims to foster collaboration (within individuals, materials and disciplines), explore networked pedagogy and networks in pedagogy as a collaborating force through and with the visual arts and explore the materiality of the code and the digital media. The course also engages with new media theory and literature, investigates the materiality of the digital media as collaborators, mediators and metaphors and reflects on how technology affects pedagogy and allows students to tailor projects according to their own interests. The course content is flexible in its approach with plenty of elbowroom. The 3rd Unit of the suggested curriculum also seeks to advocate for social justice; students cultivate perspectives about the power of digital media to address social issues, they probe into matters of social justice or injustice with the featured artists and make connections with the artistic processes and goals of the artists (listed in the lessons) to reflect on the sociopolitical context of their own art making. The students also think about networks as an abstract or tangible concept (digital, social, physical, and biological networks) and create works in an open-ended, student-centric environment that encourages critical thinking, independent decision-making and enables them to chose their own nature/ track of projects.https://scholarscompass.vcu.edu/cstae_resource_higher_education/1002/thumbnail.jp

A Hardware Time Manager Implementation for the Xenomai Real-Time Kernel of Embedded Linux

Nowadays, the use of embedded operating systems in different embedded projects is subject to a tremendous growth. Embedded Linux is becoming one of those most popular EOSs due to its modularity, efficiency, reliability, and cost. One way to make it hard real-time is to include a real-time kernel like Xenomai. One of the key characteristics of a Real-Time Operating System (RTOS) is its ability to meet execution time deadlines deterministically. So, the more precise and flexible the time management can be, the better it can handle efficiently the determinism for different embedded applications. RTOS time precision is characterized by a specific periodic interrupt service controlled by a software time manager. The smaller the period of the interrupt, the better the precision of the RTOS, the more it overloads the CPU, and though reduces the overall efficiency of the RTOS. In this paper, we propose to drastically reduce these overheads by migrating the time management service of Xenomai into a configurable hardware component to relieve the CPU. The hardware component is implemented in a Field Programmable Gate Array coupled to the CPU. This work was achieved in a Master degree project where students could apprehend many fields of embedded systems: RTOS programming, hardware design, performance evaluation, etc.Comment: Embed With Linux (EWiLi) workshop, Lorient : France (2012

The political economy of the Malaysian subnational governments' fiscal behavior

This article attempts to shed light on the political economy of the Malaysian state governments’ budgetary behaviour by tailoring hypotheses drawn from recent theoretical literature to the Malaysian institutional context and testing them empirically. The main objective here was to examine whether state governments’ fiscal behaviour can partly be explained by the political attributes and the institutional characteristics of the government, and of the legislature. In particular, the study analysed whether the incentives for the state governments to observe a prudent spending behaviour have not been undermined by the fact that they have been able to influence relevant central government decisions regarding their finance. The estimation results showed that states that are over-represented at the executive level tend to have higher spending and deficits. However, no correlation was found between over-representation at the parliament and state governments’ fiscal outcomes. This can be explained by the fact that in Malaysia, as is frequently the case in developing nations, the legislature is peripheral to the executive in terms of decision-making power

Is There Any Role of Technological Inputs? A District-wise Analysis of Output Differential in Crop Sector

An investigation is performed to analyse the impact of technological inputs accompanied with traditional inputs over different periods of time on the output differential of four major crops including Wheat, Rice, Cotton and Sugarcane. Data related to different districts of the Punjab province have been used to conduct the study. A multivariate statistical analysis is applied for this purpose, in which principal component (factor) analyses is carried out as a first step to reduce the dimensionalities in the data and to obtain the ranking of districts in two phases of time i.e., 1971-75 and 2001-05. Further analysis is made by developing indices on the basis of few selected top and low ranked districts four each; along with one more district as a special case due to pronounced improvement in its ranking. Technological inputs showed consistency and significant contribution towards crop output over the time with some district wise differentials.Technological Inputs, Crop Output, Index, District
