Improved Adaptive Particle Swarm Optimization for Wide Null Steering of a Linear Phased Array antenna[ ]


This work is concerned with using a methodology for eliminating the effect of unwanted interference in a certain direction applied to the radiation pattern of a linear array antenna. An efficient method based on Particle Swarm Optimization is used .The amplitude of the elements in the linear array antenna is optimized in order to achieve nulls at the positions of the interference. The proposed Improved Adaptive Particle Swarm Optimization (IAPSO) is an efficient method applied for optimization. The Dolph-Chebyshev array is used to show the success of obtaining nulls at certain identified positions where interference occurs. The results shows the efficiency of the proposed technique in achieving perfect wide nulls with depth of -75 db using 1700 iterations as the maximum number of iterations. Sensitivity and robustness of the proposed algorithm are tested at different array antenna systems with different properties which prove the effectiveness of the technique proposed in achieving the property of interference cancellation. Further, the side lobe levels and the main beam width are preserved at their original levels of the main signal without being increased.

Biocompatible Scaffolds from Chitosan/Cellulose Acetate & Blends therefrom[ ]


Tissue engineering is a very important field in biomedical applications such as in skin regeneration, nerves, liver, cartilage, heart valves, etc., of which the essential requirements are to prepare suitable scaffolds that are biocompatible, biodegradable and of uniform pore-size. Natural biocompatible polymers such as chitosan (CS) have been often explored in the preparation of scaffolds, that are later seeded with cells, in bioreactors, for replacing burnt or damaged skin. In addition, regenerated cellulose, such as cuprophane, has been the membrane of choice for blood purification by the artificial kidney, for decades. Accordingly, in this work scaffolds were fabricated from either CS or cellulose acetate (CA), or blends therefrom, by a simple novel laboratory technique, in which the polymer/polymer blend is dissolved in a suitable solvent/solvent mixture, to form solutions which are cast by a special casting assembly into membranes, such that pores and scaffolds are created, by forcing humid air to flow along the as-cast membrane. CS was prepared from shrimp shells through deacetylation with concentrated sodium hydroxide (NaOH) solution. Variables investigated were: type of polymer, type of solvent, initial polymer solution concentration, concentration of deacetylation solution, and time of exposure to humid air flow of as-cast membrane. Scanning Electron Microscopy (SEM) examinations were conducted to determine membrane surface and cross-section morphologies, and it was found that CS gave a suitable surface and that the blend membrane gave a better membrane as regards the number of pores, while CA gave promising scaffolds. Moreover, the type of solvent affected the membrane morphology, and deacetylation with 50% NaOH solution gave a more uniform CS membrane than lower concentration. Moreover, it was shown that a 30 min exposure time gave a membrane with more scaffolds/pores >20 min >10 min. The scaffolds suggest that they might be suitable for formation of replacement skin tissue, after cell seeding, in future work, which is currently proceeding in our lab.

MATHEMATICAL MODELLING AND SIMULATION OF A PARTIALLY SHADED PHOTOVOLTAIC MODULE[ ]


Photovoltaic installers are very much concerned with photovoltaic systems working under shaded conditions and this has led to detailed research in this domain. We show in this paper that the electrical power produced by a partially shaded module is greatly reduced as compared to when operating under its optimal conditions. With the aim of having a better understanding of the impact of shading on the production of a photovoltaic module and thereby estimating the economic efficiency of a photovoltaic system, we have also worked on the modelling and simulation of a partially shaded photovoltaic module. The method used consists of first, modelling the current-voltage characteristics of the photovoltaic cells independently and then, summing them up according to the electrical configurations of the module. The results show that the bypass diodes reduce negative effects of shading on the production of electricity of a module. An estimation of the power loss is made at the maximum power point under shaded conditions.

The rod shaped gram negative, an aerobic, motile hydrocarbon degrader Rhodococcus rhodochrous was isolated from the petroleum contaminated soil of Mount Abu, the high altitude region of Rajasthan at 4003 feet. Poly Aromatic Hydrocarbon degrading bacterial strain was isolated by enrichment culture technique in Bushnell Hass medium in the presence of 2T engine oil as a sole source of carbon and energy. The evaluation parameters like Optical density (OD), total petroleum hydrocarbon (TPH) and gas chromatography and mass spectroscopy were used as the major indicator of microbial degradation of 2T engine oil at concentration of 1% (v/v). The physico-chemical analysis of the petroleum contaminated soil samples was analyzed and their effect on the rate of degradation was determined. By GC-MS analysis it was observed that the 2T engine oil and the contaminated soil was highly polluted with the hydrocarbons of LMW as well as HMW ranges from C1-C50. The maximum height of peaks were of medium fractions ranges of C11-C20 on day 14 which were with 78.07%, which were 58.55% on day 7. They appeared due to the reduction of peaks of C21-C30 from 22.24 % to 3% on day 7-14 respectively. The maximum degradation of 2T engine oil hydrocarbons with 62% was observed within 14 days of incubation period by the conversion of higher alkanes to their lower forms by gravimetric method. Apart from the degradation, also the secondary metabolites were produced by the Rhodococcus rhodochrous which have a wide application in the field of medicines, dyes etc. The organism Rhodococcus rhodochrous showed remarkable potential for use in degradation of 2T engine oil.

Analysis of dynamical rain duration and return periods for terrestrial and satellite communication applications in a tropical climate[ ]


Understanding the intensity, duration and return periods of tropical rain events are critical to radio and satellite system engineers. As current and future satellite systems use and will use higher frequency bands, rain attenuation continues to pose more threat to link availability for microwave propagation operating in the frequencies above 10 GHz. Despite the enormous research on rain mitigations, few studies have addressed the dynamic of rain duration and return periods of tropical rain events. In this paper, an attempt has been made to analyze the dynamical rain duration and return periods for terrestrial and satellite communication applications in a tropical climate. 3-year rain rate data collected at Akure (7.17 oN, 5.18 oE) between July 2012 and June, 2015 is used. The dependence of integration time on the cumulative distribution of rain rate has been compared with results earlier obtained in Nigeria and other parts of the world. The Result shows that the power law relationship exists between the equiprobable rain rates of two different integration times. The value of conversion factors CE(R) and CR (R0.01%) obtained for Akure are 0.15(30) and 0.33(110) respectively. The overall results show that different conversion factors are required for different locations, even within the same climatic region.

A survey on Glioblastoma Multiforme Tumor Segmentation through MR images[ ]


Magnetic Resonance Imaging(MRI)-based medical image analysis for brain tumor studies is gaining attention in recent times due to an increased need for efficient and objective evaluation of large amounts of data. Gliomas are the most common primary brain tumors, evolving from the cerebral supportive cells. Brain tumor segmentation consists of separating the different tumor tissues (solid or active tumor, edema, and necrosis) from normal brain tissues: gray matter (GM), white matter (WM), and cerebrospinal fluid(CSF). Currently, most of brain tumor segmentation approaches arise from the supervised learning standpoint, which requires a labelled training dataset from which to infer the models of the classes. The performance of these models is directly determined by the size and quality of the training corpus, whose retrieval becomes a tedious and time-consuming task. On the other hand, unsupervised approaches avoid these limitations but often do not reach comparable results than the supervised methods. This article presents an overview of the most relevant Glioblastoma multiforme tumor segmentation methods, conducted after the acquisition of the image. Both Supervised and Unsupervised techniques are emphasized.

Comparative Study of Soil Stabilization Using Human Hair and Lime[ ]


Recent issues regarding solid waste disposal demands novel methods for their proper utilization. Environmental problems associated with Human hair fiber, a non- degradable matter can be minimized by using the same as a reinforcing agent in soil stabilization. Studies shows that Human hair fiber, as a cheap reinforcing agent, can be used for stabilizing clayey soil found in low lying areas of Kerala, India. Study is conducted to stabilize clayey soil using human hair fiber and to compare it with the classical method of lime stabilization. Human hair fibers randomly mixed in clayey soil samples were tested for its engineering property (Strength) by performing UCC tests on a number of samples by using different percentage of fibers and comparing the results with the non-reinforced soil and lime-stabilized soil. Human hair of length 4-40mm and of diameter 40-110µm were used. The test result reveals that the strength significantly improves with the inclusion of Human hair and it further improved when optimum percentage of both lime and human hair were added together. Thus soil properties of low-lying areas can be improved to a great extend while suggesting a solution to a major environmental issue of human-hair disposal.

Application of Nanotechnology in Cancer[ ]


This paper gives the theoretical application of the Nano devices in the cancer treatment. The recent technology for the cancer treatment is the chemographic method. In this method the specific composition of drugs are given to the victims or the patients depends upon the biopsy of the tumor which the patient is having. The main disadvantage of this method is that the drug used is not specific and it can damage the surrounding healthy cells in which no tumor occurred. To avoid this problem the Nano devices will be very effective that uses the Nano sensors to sense particularly the damaged cells. So the efficiency of the operation is very high. This paper is only the theoretical proof for the treatment of the cancer. But there is a great possibility to implement this method.

RSA and Triple DES based Combined Secured Approach to Ensure Data Security[ ]


Data security is a key concern of today’s worlds. Data security is critical for most businesses and even home computer users. Client information, payment information, personal files, bank account details - all of this information can be hard to replace and potentially dangerous if it falls into the wrong hands. Data lost due to disasters such as a flood or fire is crushing, but losing it to hackers or a malware infection can have much greater consequences. Cryptography techniques employ to ensure data security in this regard. For this, RSA and Triple DES technique has been studied, realized and implemented with strong authentication, confidentiality and message integrity. First, the key pairs have been generated for the users to perform the encryption and decryption. Public key pair (e, n) is used for encryption and for decryption corresponding private key pair (d, n) is used. For key generation, first select two large primes: p, q, and compute the modulo factor, n =p x q and, calculate the totient factor, ?(n)= (p-1) x (q-1). All the co-primes are listed for this totient. Then two co-prime e and d are chosen with property that e d =1+k ?(n). Generated key pair (e, n) is used as public key and (d, n) is used as private key. The plaintext message M is processed with a hash digest X, produced by X-OR, a hash function and appended it with M, which is then encrypted with the sender’s own private key to generate cipher text C. Then C is further encrypted using triple DES encryption algorithm along with a secret key KS. The secret key KS is also encrypted with the receiver’s public key. The encrypted secret key along with the encrypted data is sent to the destination. In the receiver end, the received encrypted secret key KS is first decrypted using receiver’s private key and then encrypted data is decrypted with KS ¬that generates cipher text C. C is now further decrypted using sender’s public key to obtain original message M and a hash digest X. Then the receiver applies the X-OR function repeatedly to generate a hash digest X' and compare it with received digest X to ensure data integrity. The use of the secret key establishes the strong confidentiality and the uses of the sender’s private key ensure the authentication by creating digital signature. The proposed system can be applied for many cryptographic applications like business transaction, small organization, file transaction etc. where strong security is highly demanded.

Attrition Prediction- Need of the Hour for Companies[ ]


In today’s world many industries and specially IT (Information Technology) are experiencing high attrition rate. Managers and HR department are aware of some common causes of attrition in their organization. The impact of employee leaving voluntary is not good for organization or to project in which they are working. Hence HR and senior managers and the policy makers of any industry are working together to reduce this voluntary exit. A good leader senses and understands employee needs and work with them and HR to fix the issues. However not all attrition causes are known to managers and when it actually happens it turns out as a surprise to managers, then they are not able to do much. In-spite of many efforts taken attrition is still a problem in many industries. Some amount of attrition is certain and bound to happen like employee retiring or death of employee hence the scope of this work is only restricted to voluntary exit.

A robust mean shift integrating color, GLCM based texture features and frame differencing[ ]


Mean shift is a kernel based widely used algorithm for tracking the location of object robustly. Classical mean shift uses color histogram to represent the object. However, the use of only color restricts the algorithm to track the object only in simple cases and it fails in complex situations like illumination changes, occlusion, and abrupt changes in the location of object. To improve the performance of mean shift, some authors have added some features to basic mean shift. As color based target representation is combined with texture-based target representation, based on spatial dependencies and co-occurrence distribution within interest target region for invariant target description, which is computed through so-scaled Haralick texture features, is an efficient mean shift for target tracking in some real world complex conditions. But it still fails, if there are some abrupt changes in the location of object. So a novel algorithm is presented in this work, which is robust to track the object in above mentioned complex situations. It is the combination of color and gray level co-occurrence matrix based texture features along with the use of frame differencing for abrupt motion changing target detection.
