LIE addresses the escalating demand of data rates by introducing several multiple-input and multiple-output (MIMO) transmission modes. One of the potential MIMO technique is to send independent data streams over multiple antennas. This is known as spatial multiplexing. The simplest form of spatial multiplexing is open-loop spatial multiplexing (OLSM). The performance of OLSM can be improved further by using an extra feedback information sent back by the user equipment (UE) to the base station (BS). This is termed as closed loop spatial multiplexing (CLSM). Data is transmitted in the form of packets called resource blocks (RBs) and the distribution of RBs among active UEs is determined by the scheduler present at the BS. Scheduler performance ranges from optimizing the UE fairness to maximizing the UE throughput and can have a significant impact on the overall system performance. A prominent constraint that degrades the MIMO performance is the UE mobility. In this paper, we have analyzed various LTE downlink performance parameters between OLSM and CLSM under different scheduler algorithms to conclude which spatial multiplexing and scheduler combination is best suited for mobile users in a heterogeneous network (HetNet).

DNA contains the information of structure and function of different molecules of any living being. Short repeating patterns in a DNA sequence, called Motifs, are useful to understand and analyze this information. Recent advancements in gene expression analysis already prompt the scientists to introduce a number of motif finding algorithms. Among different motif search problems, one of them is Planted Motif Search (PMS). In this paper, we have proposed an approximate algorithm for Planted Motif Search which at first generates all possible motif set and use a bucketing concept to find out the proper motifs from the whole dataset. Two benchmark datasets of DNA sequences are used to evaluate the performance of the proposed method and its comparative analysis with other approaches. Experimental results demonstrate that proposed bucketing approach is more robust than the other approximate algorithms providing more amounts of motifs within less amount of time. Most of the time, above 80% of the possible motifs of the given input set are found within a reasonable time.

Recently, second-order-to-second-order structure preserving model order reduction (MOR) has received a lot of attention. One of the most prominent techniques of such MOR is balanced truncation (BT). In general, this method does not preserve some essential properties of the system; such as stability and symmetry. This article discusses a new projection method for structure preserving model reduction of second-order systems via projecting the system onto the dominant eigen-space of the Gramians of the systems. The proposed method preserves the stability and symmetry of the systems. Numerical experiments are discussed to show the efficiency of the proposed technique.

Extensive data analysis and a huge computational power is required in every computational grid application such as distributed supercomputing, high-throughput computing etc. Task Allocation strategy plays a vital role in the grid environment in terms of assigning the task to the appropriate ants of the colonies within a satisfactory allocation time. The uncertainty of available supply energy for completion of a task makes the allocation policy for grid computing more challenging. In this paper, we propose a fuzzy-based method for allocating the task among the members of an ant colony under grid computing and try to minimize the time consumption of task allocation. We believed and observed, our proposed model offers an improving performance comparable with traditional approach of allocating task in full assigning or no assigning. Our proposed method, based on the task and energy available from the grid and ants respectively, chooses the distribution of a task in full, half or no task assigning to ants by using fuzzy logic. During arriving of a task, ants will perform and execute the assigned task by using first in first out method. Successful task allocation, as reaching to equilibrium state will be achieved by allocating the task with half supply energy available from the colony. We show that with the use of fuzzy logic under grid environment task allocation problem shows an enhanced efficiency for assignment of tasks among the members of an ant colony.

It is well known that the iterative spectral subtraction (ISS) method is effective to eliminate white noise in speech, the fact that the ISS method is suitable for restoration from image degraded by white noise has been confirmed. In this paper, we presents an image denoising technique in which an iterative extended spectral subtraction (IESS) method is developed. We discuss the factors of the IESS that affect the restoration results, and by setting the best parameters, set out to improve the performance. We compare the performance of the IESS method with that of state of the art filtering approaches in experiments.

Parsing is one of the most challenging task in the field of natural language processing and it plays an important role in order to analyze any natural language. To determine a legal structure for a sentence, we need to expose the rules of how sentences of a language are embodied and have a parsing algorithm to analyze sentences using those rules. This paper proposes a new technique to parse the Bangla sentences including imperative, optative and exclamatory sentences using a set of context sensitive grammars (CSG's) rules. This paper considers Bangla sentences based on the intonation or mood of the sentences rather than the structure of the sentences for parsing. The proposed framework can parse Bangla sentences with over 81% accuracy which is quite satisfactory.

In this paper, we present a method for the detection of fruits from images. Several fruits detection techniques have been developed based on colour and shape values. However, different object images may have similar or identical colour and shape. Therefore, using only colour and shape features are not efficient enough for fruits detection. Considering this fact, in this paper, we propose a method using colour, shape and texture for detecting objects from images. We performed several experiments using fruits images and found that our system can almost accurately detect fruits types from images.

A controller is designed to get desired output from the proposed converter. Switching signals for two different modes are generated using the controller. The mode of operation of the proposed converter will be determined by a control signal given by user. The input is AC in both modes of operation. Necessary simulations are performed in PSIM.

A novel design of a microstrip line-fed flexible on-body matched Ultra-Wideband (UWB) antenna is proposed in this study. Small and flexible design along with noteworthy performance of this proposed antenna upholds its strong position amongst previous antennas of similar type and can be used for various biomedical applications. The antenna is designed to operate in the UWB (3.1–10.6GHz) frequency range where resonant frequency is at 5.93GHz. The main notability of this design refers to its subtle dimension, lower sensitivity to angular misalignments and higher fidelity that makes it perfectly fit for biomedical applications, especially in Wireless Body Area Network (WBAN). Both flexible and rigid conditions of the antenna are studied here as it needs to be tested in different medium which will more effectively corroborate future practical implementation. Several types of calculations and performance measurements of this antenna have been completed by using CST MW studio while maintaining all the dielectric properties of human tissue. With overall dimension of 40mm × 40mm × 1.44mm, the antenna is placed upon a three layered human phantom model to run simulation process where FR4 is used as substrate and copper is used as patch material. Performance analysis of the designed antenna is evaluated in terms of return loss, bandwidth, radiationpattern, directivity, gain, total efficiency and power analysis. Finally, Specific Absorption Rate (SAR) distribution of the antenna is analyzed to make it perfectly biocompatible for practical use.
