Bit Error Rate analysis of efficient wireless channels in WiMAX for an image transmission using concatenated RS-LDPC coding techniques

: Wireless technologies offer significant benefits over wired, such as including low installation cost, rapid deployment, and mobility and so on. Wireless technologies are suitable for remote end applications. It is a challenging task to successfully transmit an image to the receiver with a very low bit error rate (BER) because of the presence of the noise in wireless channels. According to the user needs such as requirement of smaller bandwidth, high data rates, the wireless communication has undergone through the significant developments. In order to overcome the limitations of current technologies such as the presence of Inter Symbol Interference (ISI), multipath fading, availability of scarce resources, use of more efficient wireless systems is necessary. WiMAX is the most promising and upcoming 4G wireless transmission technologies that fulfil the user needs. Application of concatenated Reed Solomon-Low density Parity Check (RS-LDPC) codes with the WiMAX system ensures the reliability and efficiency of the system. This paper analyses the WiMAX system performance under various channel scenarios (Additive White Gaussian Noise (AWGN), Rayleigh and Rician fading channels) by applying concatenated RS-LDPC coding technique. The performance is evaluated by calculating the BER for different values of Signal to Noise Ratio (SNR).
Screening of some Medicinal Plants for their Antityrosinase and Antioxidant activities

The present study was designed to appraise the depigmenting and antioxidant abilities of five medicinal plants. The various solvent extracts of medicinal plants were prepared by using decoction method. Mushroom tyrosinase was used as the model system for evaluating the antityrosinase activity of plant extracts. The results of the study show that the aqueous extract of Asparagus racemosa (43.29%) exhibited the maximum inhibiting potential of the tyrosinase enzyme. The antioxidant ability of the plant extract was determined by using the 2, 2-diphenyl -1-picryl hydrazyl (DPPH) radical scavenging assay. The aqueous and ethanolic extract of Holarrhena antidysentrica was found to have the highest inhibition of DPPH radical amongst the plant extracts tested. The plant extracts were also quantified for their total phenolic content. The aqueous and ethanolic extracts of Pachygone ovata were found to possess the greater phenolic content. From our findings it was concluded that the aqueous extract of Asparagus racemosa can be used as an active to inhibit tyrosinase and protect the skin from free radical toxicity.
Energy Efficient Low Complexity I-MRC Detection of SM-OFDM Systems in the Presence of AWGN Channel

Spatial modulation is a recently proposed and developed technique to exploit the spectrum efficiency of multiple-input multiple-output system , reducing the decoding complexity and increase specrum efficiency as compaired with MIMO system. By using an proper combination of number of transmit antenna (N t ) and number of transmit RF chains (n rf ), SM may achieve superior output and bit error rate (BER). the SM system gains advantages in various aspects such as receiver complexity, hardware implementation, energy efficiency, etc. In this paper, a low complexity detection schemeis projected to lessen the complexity of detection in spatial modulation orthogonal frequency division multiplexing (SM-OFDM) systems.specially, the projected scheme employs a novel maximal ratio combining iterative detector to the SM-OFDM systems with AWGN channels. Simulation results demonstrate that the proposed scheme is capable of effective detection and of providing about considerable system performance with low comlexity compared to the conventional parallel interference cancellation (PIC)-aided maximum likelihood (ML) detector and ss detection at a moderate cost.

Dawood H. Dawood. Methanolic (MeOH) extract and crude polysaccharides of Plumeria alba leaves were evaluated for in vitro antioxidant activity. Antioxidant activity was evaluated at different concentrations ranged from 0.25 to 3 mg/ml using three different in vitro antioxidant activity assays. The monosaccharide composition was performed on a Dionex system (Dx-120) ion chromatography. Total phenolic compounds and total flavonoids were determined. HPLC analysis for the MeOH extract revealed the presence of ten flavonoids and nine phenolic compounds with higher antioxidant capacity. The detected polysaccharides are heteropolysaccharides, glucose and mannose were occupied the highest level followed by galactose and rhamnose. Additionally, Plumeria alba polysaccharides (PAPs) consisted of the protein-bound polysaccharide. Furthermore, 14 amino acids (Asp, Thr, Glu, Ser, Ala, Gly, Arg, Tyr, Cys, Ile, Lys, Val, Pro and Phe) were identified to be components of the protein-bound polysaccharide analyzed by automated amino acid analyzer. The obtained results clearly indicated that the MeOH extract and PAPs showed a strong antioxidant activity in terms of FRAP, DPPH• free radical scavenging and reducing power assay. Thus, Plumeria alba could be a new source of natural antioxidants for functional foods or medicine due to its higher antioxidant potential, flavonoids and phenolics contents
Performance Comparison of Wavelet Transforms, Generated from Orthogonal Transforms, in Classification of Image Database

— Thousands of images are generated every day, which implies the need to build an easy, faster, automated classifier to classify and organize these images. Classifying the images based on visual content is an important and challenging problem today. Feature extraction is a major step in a classification as the accuracy of the classification depends on it. This paper presents the use of wavelet transform to generate the feature vector. Wavelet transform is generated from orthogonal transform matrices of two different sizes. This wavelet transform is then applied to the columns of an image to generate feature vector which will represent that image. Feature extraction is done for training as well as testing images. Euclidean and Manhattan distance criteria are used as a similarity measure. Matching is done using nearest neighbor method. The paper also compares the performance of orthogonal transforms and their wavelet transforms in classification task. The results have shown that the performance of wavelet transform is far better than their respective orthogonal transform
COMPARATIVE STUDY TO EFFECT OF NUCLEO CMP FORTE AND PLATELET RICH PLASMA ON THE REGENERATION OF SCIATIC NERVE IN DOGS

The objectives of this study were to evaluate the efficacy of each Cytidine Monophosphate and Platelet Rich Plasma on the regeneration of sciatic nerve injury of dogs. Eight healthy adult dogs were used to complete this study. They were randomly divided into two equal groups: Platelet Rich Plasma group and Cytidine Monophosphate group. The sciatic nerve axotomy was done on the right hind limb at the middle femoral bone and then the nerve coaptated immediately by nylon suture 0 5 with end-to-end anastomosis, using simple interrupted suture, and then the activated platelet rich plasma was injected immediately at the site of coaptated nerve at subepineural site but in Cytidine monophosphate group, the dogs are treated with Cytidine monophosphate 5 mg/day intramuscular for 30 day post operation. The clinical examination of animals show occurrence (onset of gait, knuckling, swelling and pain at the operated leg) that were evaluated from the start until the end of the study (sixteen week). Clinically, the cytidine group show faster improvement compared with Platelet Rich Plasma. Macroscopic examination was done for evaluating the presence of nerve stump coaptation, adhesion, thickness and neuroma. A good coaptation was observed in cytidine compared with platelet rich plasma groups. While the adhesion appeared in variable degrees in platelet rich plasma group, otherwise, it was appeared in one animal in cytidine group. Moreover, no thickness or neuroma was present in two groups. The Electrophysiological examination (conductive velocity) was carried out by adinstrument after isolation of the sciatic nerve on 16 th weeks postoperative, the results showed significant differences at (p≤0.05) in the same group between right (operated) and left sciatic nerve. Furthermore, significant differences between groups at (p<0.05) are the best conductivity in Cytidine monophosphate group compared with other group. The histopathological examination of proximal, middle, and distal segments of sciatic nerve sections (three parts along each one 1cm) are isolated, and used to evaluate the sciatic nerve regeneration. The neurohistopathological results that showed increase proliferation of Schwann cells and orientation of regenerative nerve fibers are observed most clearly and improved in Cytidine monophosphate group compared with platelet rich plasma group.

Image Classification Using Class-Specific Codebooks and Distinctive Local Features with CSO based ANN Classifier

The number of digital images has been increasing exponentially in the last few years. People have problems managing their image collections and finding a specific image. An automatic image categorization system could help them to manage images and find specific images. In this paper, we present a novel method for Image Classification Using Class-Specific Codebooks and Distinctive Local Features with hybrid classifier. Initially, we produce more useful codebooks by utilizing the Self Organizing Map (SOM) clustering and class-specific codebooks in the bag of Words (BOW) model. This contributes to the enactment of the classification performance. Then, the scalability of the image classification system is upgraded by employing a supervised clustering method in codebook generation composed with utilize of distinctive image features during the classification step. Finally, our feature selection method increases the classification performances also here we design a new optimal hybrid classifier called Cuckoo Search Optimization (CSO) based Artificial Neural Network (ANN) which also increase the performance. The proposed method is implemented on Matlab platform and tested on standard database The PASCAL Object Recognition Database Collection and performance are evaluated.
Automatic Test Case Generation using Genetic Algorithm with Antirandom Population

: Reliability is a most important quality attribute of software which is to be achieved thorough software testing, the most effort consuming activity, success of which depends upon the adequacy of the data and all the criteria discussed in the literature are incomplete. There is the need of automatic test case generation so that the cost of testing can be reduced. In this research paper, Genetic Algorithm is used to automatically generate the test cases using the antirandom testing technique and the results are verified using n-versions of the module. Mutation adequacy is used to verify the completeness. The results of the Genetic Algorithm with random population and hamming code are compared and improvements have been observed over random and hamming code testing.
The Coupled Cardiac Action Potential Pulse (CAPpulse) – Synchronised Oscillating Mechanical Pulse Cardiac Action Potential

Fundamental to the functioning of the heart its efficiency and lifetime durability is the control of its speed of contraction. Contemporary thinking supposes that contraction occurs by the Cardiac Action Potential (CAP) that can be measured easily and has its origins from trans-membrane ‘ion-currents’ propagating through ion channels along the surface of a membrane. However, as this study demonstrates mathematically and empirically, cable theory is an imperfect model for describing the AP and for subsequent electromechanical coupling in the heart. Assumptions of almost instantaneous activation of progressive ion channels to produce the Cardiac Action Potential are wrongly based upon electrostatic charge travelling from one channel to the next at or near the speed of transmission: empirical evidence from channel spacing, ionic radii and diffusion coefficients demonstrate mathematically that this is not the case. Further scrutiny is therefore required, particularly as one in four deaths is caused by cardiac irregularity. However, evidence exists from ion channel studies and entropy measurements of membranes for a synchronous oscillating cardiac action potential mechanical pulse structure that is efficient and fully explains the speed of transmission: this paper proposes this model as a foundation for consideration in further studies of the heart. Understanding of the activation spread and speed of contraction is essential in any study or clinical application of the heart. The Coupled Cardiac Action Potential Pulse explains these mechanisms. This is a more consistent model for cardiac pulse activation: it is consistent with observed studies and the principle may be applied to other types of muscle. This paper is a derivative of: The Action Potential Pulse (APPulse) – Synchronised Oscillating Mechanical Pulse Action Potential [1].
An Extensive Insight On Physico-Chemical Characterization Of Hot-Melt Coating Excipients

Hot-melt coatings (HMC) are widely used to provide drug protection, to increase aesthetic value of products, to reduce acidity if vitamins, to provide lubrication and modified drug release. In hot-melt coating the substrates are coated with molten form of coating materials. Substrates used for coating are beads, capsules, granules, pellets, pills, spherules and tablets. Hot-melt coating devoid of solvent use, solvent disposal, solvent evaporation and solvent treatment is not required; as a result powders with very high specific surface areas can be coated rapidly. HMC technique not only protects the operators from solvent but also protect the environment. Hot-melt coating materials are mostly hydrophilic as well as hydrophobic in nature. Majority of hot-melt coating materials are obtained from natural, semi-synthetic and synthetic sources. Generally, lipids are the smart option to polymer coatings as they need melting before application directly on the substrate and make the technique cost effective. Depending upon sources of the lipids, the physico-chemical properties of them may change. Different lipids can be used in coating and selection of the right lipid for the application requires knowledge of their physico-chemical properties and its associated effect on drug release.
Ontology based Comprehensive Architecture for Service Discovery in Emergency Cloud

— Disasters such as Tsunami, Landslides, and cyclones occur frequently and a strong emergency management system is required to manage such situations. These kinds of crisis circumstances are expected to increase in future. The role of Information and communication technology can largely aid in handling calamities and provide first aid support. The characteristics of Cloud computing such as sharing on demand, connecting communities and offering everything as a service clearly indicate that it can contribute to crisis without affecting business continuity. Hence efforts have taken to articulate web services and the cloud infrastructure as ontology, in the perspective of emergency management which can improve the understanding of this proposed agent based comprehensive architecture.
Mental health in Mozambique; a systematic review

The World Health Organization (WHO) defines mental disorder (MD) as an adulteration of thought and emotions, produced by inadequacy or deterioration of psychosocial functioning depending on biological, psychological and social factors.1 At the world level, neuro-psychiatric conditions are the greatest cause of disability, being responsible for more than 37% of years of life with disability in individuals over 15 years old (DALYs). The burden of disability due to neuro-psychiatric conditions is similar in both genders, but main causes are different: depression is the main cause of disability for men and women, but the burden of depression is 50% higher in females who also present a higher incidence of anxiety disorders, migraine and senile dementia; men present a burden of disorders related to the consumption of alcohol and drugs almost six times greater than women, responsible for a quarter of the burden of neuro-psychiatric diseases.2 More than 85% of the disease burden caused by non-fatal diseases occurs in lowand medium-income countries, and South Asia and sub-Saharan Africa account for 40% of the loss of disability adjusted life years (DALYs). MD etiology is multi factorial: genetic contribution should be evaluated, along with obstetric complications and perinatal hypoxia (associated with schizophrenia mainly in men). We know that mentally healthy individuals benefited from greater security, much emotional support and moderate control. Parental or maternal style may also increase vulnerability by influencing personality development. The “cognitive model” assumes that people’s emotions and behaviours are more influenced by their perception of events than by the facts themselves. “Core beliefs” influence the way we respond mentally to life situations; negative “central beliefs” lead to worse MH than the opposite “central beliefs” alternatives. We must also include brain lesions, caused by toxic drugs, illicit drug use, and head trauma.3
AN OUTPUT-CAPACITOR-LESS LOW DROPOUT (LDO) VOLTAGE REGULATOR WITH SUPERIOR TRANSIENT RESPONSE

In this paper, an output-capacitor-less Low Dropout (LDO) Voltage Regulator implemented in a standard 0. 13μm CMOS process is introduced. The proposed scheme makes use of Bulk Modulation Technique for improving the performance of low-drop-out (LDO) voltage regulators. Improvements in load driving capability and recovery time when the technique is applied to a conventional LDO regulator are confirmed. The proposed LDO regulator has ~1.5% load regulation and is able to delivers up to 5 mA of load current while providing 1 V drawing 99.0 μA from a 1.2 V supply. It has been observed that the proposed circuit offers better stability as well as improvement in the load current delivery and recovery time of 0.16 μs for no-load to full-load and fullload to no-load transitions. KEYWORDS—Bulk modulation technique, capacitor-less LDO, power supply rejection, low-drop-out voltage regulator, low-power, recovery time.
Utilization of Combined NDT in the Concrete Strength Evaluation of Core Specimen from Existing Building

In this paper, a series of compressive strength of core specimen’s to correlate the rebound hammer indices and UPSV results obtained from member of existing buildings. The combined method (SONREB) was used to quality control and strength estimation of the concrete. This combined method requires short time to obtain the results, it’s a non-invasive method and it does not affect the resistance of structural elements. The best fit equation of SONREB method for the determination of concrete compressive strength is obtained through processing correlation among the data sets. Finally the investigation and comparison of experimental results of non-destructive tests and core strength with the help of statistical data obtained by testing of specimen as per recommended procedures by IS 13311:1992 and IS 516:1959 respectively. The use of the combined methods (SONREB) increases the accuracy of the estimation of the in situ concrete compressive strength.
Effect of Chemical and Biological Fertilizers on Quantitative and Qualitative Yield of Artichoke (Cynara scolymus L.)

In order to evaluate the effect of different nutritional treatments on forage yield and some qualitative traits of artichoke (Cynara scolymus L.), an experiment was conducted as factorial experiment on the basis of RCBD design with three replications in Isfahan Agriculture and Natural Resources Research Station, Iran during 2014. The first factor consisted of chemical fertilizers at levels of 100% chemical fertilizer (200-100 kgha NP), 50% chemical fertilizer (100-50 kg ha NP), and control. The second factor comprised biofertilizer at levels of 1 liter ha Nitroxin (include Azotobacter, Azospirillium and Pseudomonas), 100 gha Barvar 2 (include Pseudomonas potida and Bacillus lenthus), 1 liter ha Nitroxin +100 gha Barvar 2 and control. The results showed that soil fertilization treatments significantly affected forage quantity and qualitative traits of artichoke. The effects of chemical fertilizers on the majority of traits in artichoke were statically significant, however, there was no significant differences between treatments in about ash%. The interaction between biological and chemical fertilizer was significant on all traits. The best quality and forage yield were obtained in integrated plant nutrition. The highest dry matter yield (12.1 t ha), crude protein (19.53%), phosphorous content (622.2 mg/kg) organic matter digestibility (86.56%)were obtained by Nitroxin + Barvar 2+ 100% chemical fertilizers (urea + triple super phosphate). The control treatment had the highest acid detergent fiber % (ADF) and neutral detergent fiber % (NDF). In general, results showed that seed inoculation with biofertilizer in the integration with chemical fertilizers improved forage yield and quality of artichoke. The application of bio fertilizers alone could not fulfill the nutritional requirements of artichoke. It seems that it could be used as a complementary fertilizer with chemical fertilizer in sustainable agricultural practices.
