Abstract :

This research aims to analyze correlation between surface water quality parameters of River Kushiyara, Sylhet Division, Bangladesh on the basis of physico-chemical parameters such as Temperature, PH, DO (Dissolved Oxygen), BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TS (Total Solids), TDS (Total Dissolved Solids) and SS (Suspended Solids). Pearson’s correlation coefficient (r) is determined using correlation matrix to identify the highly correlated and interrelated water quality parameters. To test the significance of the pair of parameters p-value is carried out. There is a relationship between variables which shows that one variable actually causes change in another variable. In rainy season the highest significant correlation is found between COD & TS, TS & TDS, BOD & COD and BOD & SS. In winter season the highest significant correlation is found between TS & TDS, TS & SS, TDS & SS and Temperature & PH. The DO showed negative correlation with most of the parameters and in winter season the DO show negative correlation with all other parameter more or less, which reveals that when other water quality parameters increase the DO value decreases.

Abstract :

This paper represents to develop a new Radix Based FFT Algorithm for the analysis of Multiband OFDM and their FPGA parameters calculation, in order to reduce the complexity for the efficient operation of multiband -OFDM. This brief compares the use of multiplier less and DSP slice-based cross-correlation for IEEE 802.16d orthogonal frequency division multiplexing (OFDM) timing synchronization on Xilinx Virtex6 and Spartan-6 field programmable gate arrays (FPGAs). The natural approach, given the availability of embedded DSP blocks on these FPGAs, would be to implement standard multiplier-based cross-correlation. However, this can consume a significant number of DSP blocks, which may not fit on low-power devices. Hence, we compare a DSP48E1 slice based design to four different quantization of multiplier less correlation in terms of resource utilization and power consumption. OFDM timing synchronization accuracy is evaluated for each system at different signal to-noise ratios. Results show that even relatively coarse multiplier less co-efficient quantization can yield accurate timing synchronization, and does so at high clock speeds. Multiplier less designs enjoy reduced power consumption over the DSP48E1 Slice-based design.

Abstract :

This study will focus on the possibility of cavitation on various tidal turbine blades, constructed from four different airfoils, in particular a symmetrical airfoil, NACA 0024, and three cambered airfoils, Göttingen 770, NACA 4418 and NACA 4424. The optimum geometry of each rotor, in other words the chord length and the twist along the blade, is calculated by a user-friendly application based on the Blade Element Momentum method. This user-friendly application can also predict the power coefficient and the power output for tidal turbine rotors by examining different parameters, such as the hydrofoil profile for the blades, the number of blades, the tip speed ratio, the tidal current velocity and the rotor diameter. The flow over the optimum geometries was simulated by a commercial Computational Fluid Dynamics code for two different depths, three different blade lengths and at various tip speed ratios, in order to determine whether it is possible to occur cavitation under these operating conditions. The blade which experienced the less intense cavitation occurrence was the NACA 0024 blade.

Abstract :

A vague picture of life and death arise in the mind casting a shadow of fear and sorrow while one recounts the disease called cancer. Since the last few decades, Kashmir is experiencing a rising graph of breast cancer patients. Cancer is synonymous to death in Kashmir. Breast cancer, the most frequent cancer of women in the world is the second leading site of cancer in females in Kashmir. But more tragic is that Kashmir has a higher death rate of breast cancer patients than that of rest of India. This is partly due to the lack of awareness regarding this dreaded disease and partly due to the late presentation before a practitioner. The problem gets aggravated due to lack of resources and hence termination of or delay in proper treatment. All this amounts to the lesser survival years of patients. The high mortality rate of breast cancer patients in Kashmir can be attributed to its socio-cultural structure. The deeply rooted cultural values and traditions with respect to women folk become an obstacle in timely diagnosis and treatment of the disease. The present paper brings to fore the socio-cultural factors leading to the lesser survival years and hence higher death rate of breast cancer patients in Kashmir valley.

Abstract :

In this paper, we proposed a new detection method for a face feature point, based on facial skin color,independent of tilted face angles.We picked up the nostril and mouth as a face feature point. Human’s face was observed by a camera in real time and the skin color was utilized to detect the face domain. In order to detect the position of nostrils, we focused on the fact that the brightly-colored facial area is distributed around the nostril while the dark-colored facial area is distributed around the eye, the mouth and the jaw.Here we estimated the possibility area of existing nostril by calculating of the red component ratio. Within the estimated area, we detected the nostril position based on the conditionsa) The size of the component is close, b)    The inclination of the straight line passing through two points is small, c)    Short distance between two points. Furthermore, according to the relative position between the mouth and nostril, the mouth position could be detected.  In the test trial, we confirmed that the developed system could detected the nostril and mouth of subject successfully.

Abstract :

Soil temperature is one of the soil characteristics that greatly influences the accuracy of Time Domain Reflectometry (TDR) measurements for estimating soil moisture content. The authors examine the performance of two feedforward Artificial Neural Networks (ANN) configurations, commonly used for data regression analysis, to adjust TDR soil moisture estimates using soil temperature and gravimetric data. The data used for this study was obtained during a period of six weeks (October-November 2017) in three adjacent test sites in the Purepecha Plateau (Michoacán, México) managed under different tillage practices: at rest, reduced tillage and intensive tillage respectively. 10 TDR measurements per week were obtained from each test site. 60 Soil samples from each measurement site were also collected simultaneously, to determine the soil moisture content by the gravimetric method, and the soil temperature at 20 cm depth. 24 different configurations of ANNs were tested. The best result was obtained using a feedforward ANN with 11 tanh-sigmoid neurons in the input (hidden) layer. In addition, the authors also analyze the effect of different tillage practices on the soil moisture data. The results corroborate that tillage practices influence the soil moisture measurements and thus the best ANN results are obtained when the data used for training the ANNs is derived from sites managed under the same tillage practice.

Abstract :

Data Mining (DM) technologies are one of the vast and hot topics in today’s era. In the digital and computing world, information is generated and collected at a rate that rapidly exceeds the boundary range. It is increasing significantly in bio-medical, bio-informatics, engineering and health-care research. Large amount of biological and clinical data have been generated and collected at an unprecedented speed and scale. It seems to be a big disadvantage during storage and transmission. It raises the problem of reducing the memory size of a digital image. This research has focused on the lossy Vector Quantization (VQ) image compression to reduce the data volume in the spatial domain. We are using two unsupervised clustering algorithm for lossy VQ technique such as K-Means and K-Medoids. These two algorithms are proposed to analyze the performance in data mining and to other applications. To evaluate the clustering quality in image compression, the distance between two data points are taken for analysis. For two unsupervised clustering techniques, different block size are used as 4x4 (16) and 8x8 (64) with the codebook size of 25 and 50 in this research paper.  In spatial domain, K-Medoids was compared with K-Means in terms of execution time and quality (PSNR). The research results show that the K-Means algorithm yields the best results compared with K-Medoids algorithm.

Abstract :

The development of new technologies like robotics, artificial intelligence,and virtual reality has placed technology once again in the center of management research. A great amount of research is oriented towards the social, political and economic consequences of this so-called age of the 4th industrial revolution. One of the most important aspects of this transitional economic period is the characteristics of the internal technological change processes within organizations and the associated decision-making procedure.Introduction of new technologies can be handled with a technological determinist attitude, with a socio-technical systems approach or with a more radical processual approach. In this paper we present and describe the technological determinist approach that is dominant in the Central-European manufacturing sector.A case study method with qualitative research methodology is used to illustrate how this determinist attitude to technology is contributing to the development of work stress, control over groups of employees and impoverished jobs in a Hungarian manufacturing plant.
