Ample amount of biological data getting accumulated daily due to advancement in technologies. Microarray is such technology which captures expressions of thousands of genes at a time. Interactions occur among genes are represented in terms of special networkeknown as Gene Regulatory Network (GRN). It is constructed from Differentially Expressing Genes(DEFs). GRN is a graphical representation containing genes as nodes and regulatory interactions among them as edges. It helps in tracking pathways where usual gene interaction changes leading to malfunctioning of cells and results in illness. Also, now a day’s people are diagnosed with new diseases like dengue, swine flu, Nipah, Corona virus infection for which exact molecular pathways are yet to be invented through GRN. Therefore, in this paper, a nature inspired algorithm is used for reconstruction of GRN using differentially expressing genes.

Ancient documents are of great importance to us and accumulate a significant amount of human heritage over times. These ancient documents are in the degraded form containing vital and valuable information but the contents of the document not recognized easily. There are many causes of degradations such as environmental factors improper handling and the poor quality of the materials. In recent period, the rising interest in the historical document image analysis many researchers are attracting towards extraction of contents from historical document and preserve their contents for future generations. Numerous methods exist but they are not suitable for all types of degraded documents. The proposed method is simple, robust and based on the phase binarisation model. The proposed method is divided into Preprocessing, Post processing and extraction. The Preprocessin...

These missing values create negative impact on downstream analysis of DNA microarray. Therefore, it is necessary to estimate them before starting further analysis. Many algorithms are proposed for imputation of missing values which are based on statistical methods. They require complete gene expression data set which is created by replacing missing values by different methods like row averaging or column averaging and later missing expressions are imputed. This may affect efficiency of algorithms. In order to deal with problem of missing values, we have proposed new method based on Swarm Intelligence which is easy to implement and apply to any kind of dataset irrespective of amount of missing values in it. This method imputes missing gene expressions in microarray data set using Particle Swarm Optimization.

Load balancing can be used to extend the lifetime of a sensor network by reducing energy consumption. Load balancing using clustering can also increase network scalability. Wireless sensor network with the nodes with different energy levels can prolong the network lifetime of the network and also its reliability. We discuss the improvement to be made for future proposed load balancing schemes. This paper should provide the reader with the basis for research in load balancing schemes for wireless sensor networks.

Security plays a vital role when it comes to wireless sensor network. A malicious node can affect the network in various forms eventually disrupting the working of entire network. The paper proposes a cluster based approach to prevent a malicious node from entering a wireless sensor network. The simulation of the proposed security system helped in understanding how clustering can be useful in securing the sensor network from malicious node as early as deployment of cluster heads.

There are various Energy Efficient Protocols for WSN that are being created which aspire to successfully deliver the data packets from sensor node (source) to the Base Station. These protocols have certain parameters like distance to identify the route. These protocols have a considerable amount of energy to find the minimum distance. Our aim is to formulate a protocol which has a target to calculate an efficient path at the same time save the energy of sensors in order to enhance the lifetime of network. This paper proposed an Optimum Path and Energy Aware Sensor Routing Protocol

Although, with the development of modern technologies, multiple software's are developed. This leads to the forgery of digital images. Copy-move Image Forgery Detection is one of the forensic techniques in which selected area of an image is get copied and then moved onto the other portion of the image. In this research, the main aim is to detect the forged region from the image. A method is proposed to detect the copymove forgery in an image, by comparing extracted key points. The SIFT (Scale Invariant Feature Transform) algorithm is used for extracting the invariant features from an image and then extract blocks by using PCA.

Generally nodes are deployed in an area where human being cannot reach, therefore the small sensor nodes are usually not accessible to the user, and thus replacement of the energy source is not feasible. Hence, energy efficiency is a key design issue that needs to be enhanced in order to improve the life span of the network. In most of the existing protocol cluster head sends data directly to base station which dissipates a lot of energy, so in this paper an energy efficient approach is proposed which use the heterogeneous network of sensor nodes and multi hope approach for data transmission Keywords-Cluster Head, Energy Consumption, MATLAB, Network Lifetime, Wireless Sensor Network.

Malfunctioning occurred in cellular life is indicated by proteins which are responsible for behavior of genes. Fixed set of genes decides behavior and functioning of cells. They guide the cells what to do and when to do. To analyze the insight of biological activities, analysis of gene expressions is necessary. Advanced technology like microarray plays an important role in gene analysis as it captures expressions of thousands of genes under different conditions simultaneously. Out of thousands of genes, very few behave differently which are called as Differentially Expressing Genes (DEGs). Identifying these most significant genes is a crucial task in molecular biology and is a major area of research for bioinformaticians because DEGs are the major source of disease prediction. They help in planning therapeutic strategies for a disease through Gene Regulatory Network (GRN) constructed from them. GRN is a graphical representation containing genes as nodes and regulatory interactions among them as edges. GRN helps to know change over occurred among genes which involved in cause of genetic diseases as well as to analyze their response to different stress conditions through microarray expressions. In this paper we have discussed many methods proposed by researchers for identifying differentially expressing genes based upon changes in their expressions patterns.

Clustering can be used for load balancing to extend the lifetime of a sensor network by reducing energy consumption. Load balancing using clustering can also increase network scalability. Wireless sensor network with the nodes with different energy levels can prolong the network lifetime of the network and also its reliability. In this paper we propose a clustering technique which will balance the load among the cluster by using some backup nodes. The backup high energy and high processing power nodes replace the cluster head after the cluster reaches to its threshold limit. This approach will increase the network lifetime and will provide high throughput.
