In this paper, we propose and analyze an Adaptive Modulation System with optimal Turbo Coded V-BLAST (Vertical-Bell-lab Layered Space-Time) technique that adopts the extrinsic information from MAP (Maximum A Posteriori) Decoder with Iterative Decoding as a priori probability in t
Implicit Newton-Krylov Methods for Modeling Blast Furnace Stoves
In this paper we discuss the use of an implicit Newton-Krylov method to solve a set of partial diierential equations representing a physical model of a blast furnace stove. The blast furnace stove is an integral part of the iron making process in the steel industry. These stoves
Computationally efficient near-optimal combined antenna selection algorithms for V-BLAST systems
a r t i c l e i n f o a b s t r a c t The Vertical Bell Laboratories Layer Space–Time (V-BLAST) system using ordered successive interference cancellation (OSIC) detection is a popular system architecture featuring high data rate and moderate computational complexity. The performa
Using Delay-Fired Quarry Blasts to Image the Crust: A Comparison of Methods for Deconvolving Mixed-Delay Source Wavelets
Quarry blasts can be effective, low-cost energy sources for seismic imaging, provided that one can deconvolve the extended source signatures produced by ripple firing. This study uses real and synthetic quarry-blast data to compare the performance of several methods for deconvolv
Optimization of Trench Dimensions to Reduce Blast-Induced Ground Vibration in Gol-Gohar Sirjan Mine Using Numerical Modeling
Ground vibration is one of the detrimental effects associated with blasting that can damage the surrounding environment and nearby structures. In the Gol-Gohar mine in Sirjan, due to the surface expansion, the distance between the structures and the blasting blocks has decreased,
Significant head accelerations can influence immediate neurological impairments in a murine model of blast-induced traumatic brain injury.
Although blast-induced traumatic brain injury (bTBI) is well recognized for its significance in the military population, the unique mechanisms of primary bTBI remain undefined. Animate models of primary bTBI are critical for determining these potentially unique mechanisms, but th
Shape Optimization of Plates to Mitigate the Effects of Air Blast Loading
This report presents a formal approach for optimizing the shape of freely supported isotropic plates to withstand air blast loading. Unique difficulties are presented by the nature of shortduration dynamic loading, viz. transient dynamic response, monitoring of maximum plastic st
Low complexity antenna selection for V-BLAST systems with OSIC detection
Multiple-input multiple-output (MIMO) systems have an advantage of spectral efficiency compared to single-input single-output systems, which means that the MIMO systems have significantly higher data throughput. The VBLAST (Vertical Bell Laboratories Layered Space Time) scheme is
A quantitative model for evaluation and classification of blastings in open-pit mines
By evaluation of the blasting results, a proper blast pattern can be presented. It is, therefore, essential to employ a reliable method to evaluate blastings for the effective control and optimization of the main cycle operations. This paper aims to propose a criterion for evalua
Turbo-BLAST for wireless communications: theory and experiments
TURBO-BLAST is a novel multitransmit multireceive (MTMR) antenna scheme for high-throughput wireless communications. It exploits the following ideas: the Bell Labs layered space time (BLAST) architecture; random layered space-time (RLST) coding scheme by using independent block c
