Managers need relevant and reliable information just in time in order to make appropriate decisions to achieve organizational goals and objectives. Financial information is one of the most important types of information. Thus sound Accounting Information System (AIS) is crucial to the firms. This study tries to find out factors affecting AIS effectiveness which is a prerequisite to improvements on organizational performance. The paper examines relationship between AIS effectiveness and Managerial Knowledge, Use of External and Internal Consultant as well as Firm's Size.
In this paper a new scheme is proposed for progressive image transmission over coded Orthogonal Frequency Division Multiplexing (OFDM) system with Low Density Parity Check Coding (LDPC). Trigonometric transforms are used in this scheme for improving the performance of the OFDM systems and reducing the PeakTo- Average Power Ratio (PAPR) of OFDM signal. It improves the error resilience ability and transmission efficiency for progressive image transmission over Additive White Gaussian Noise (A WGN) channel. The Set Partitioning In Hierarchical Trees (SPIHT) algorithm is used for source coding of the images to be transmitted. In the proposed scheme the transmit data sequence of the OFDM signal after Inverse Fast Fourier Transform (lFFT) is grouped into in-phase and in-quadrature components, then each component is transformed using either the Discrete Cosine Transform (DCT) or the Discrete Sine Transform (DST). The simulation results show that adding the DST to the system im
Fiber-reinforced polymer composite materials are fast gaining ground as preferred materials for construction of aircrafts and space crafts. In particular, their use as primary structural materials in recent years in several technology-demonstrator front-line aerospace projects world-wide has provided confidence leading to their acceptance as prime materials for aerospace vehicles. This paper gives a review of some of these developments with a discussion of the problems with the present generation composites and prospects for further developments.
Orientation of cables in a suspension bridge is a major factor affecting the stability of the bridge. In this paper we are proposing a new method of controlling the orientation of cables of a suspension bridge with the help of gyro and actuators by using an appropriate control system with negative feedback.
The explanation of Time in Einstein‟s Special Theory of Relativity¹ is different from the explanation of Time in Classical Mechanics. In Relativity¹, Time is considered as fourth dimension. But, I would argue against Einstein‟s concept of Time as I do not see Time as a separate dimension. In this paper, I would explain Time Dilation and details of when and why it happens.
The heart rhythm is directly related to the electrical activity of the heart. Electrocardiogram (ECG) is generally used for obtaining information about the heart rhythm. In this paper, a method for calculating heart rhythm variation using the Phonocardiogram (PCG) and a method for finding characteristics of the that signal is described.
This paper examined logistic regression for describing the relationship between an indications of suffering from complications pulmonary tuberculosis and its associated risk factors (predictors). Logistic regression was used as a tool to see the performance on tuberculosis data.
This proposed architecture helps integrate the key ideas of this paper, i.e., a socio-technical perspective of intelligent agents facilitating the transition to the knowledge society. The social and ethical implications are discussed in the next section.
The paper tried to explore the various studies on the nexus between the productivity growth and the employment through VAR model of Dritsakis(2012) and Blanchand, Solow and Wilson(1995) model and found cointegration and causality but the association went to either direction.
: The main objective of this paper is to evaluate the consumption & investment and the market size of the cement industries in India. They play an important role in the growth of India.
