All of us rely on usage of internet for source of information. This source of information is available on web in various forms such as Websites, databases, images, sound, videos and many more. The search results given by search engine are classified on basis of many techniques such as keyword matches, link analysis, or many other techniques. Search engines provide information gathered from their own indexed databases. These indexed databases contain downloaded information from web pages. Whenever a query is provided by user, the information is fetched from these indexed pages. The Web Crawler is used to download and store web pages. Web crawler of these search engines is expert in crawling various Web pages to gather huge source of information. Web Crawler is developed which orders URLs on the basis of their content similarity to a query and structural similarity.

To search and retrieve the information from the web requires an effective and efficient technique as it has become a challenge due to expanding size and complexity of web. Web Mining tackles this problem by gathering useful information from web by using its three categories web structure mining, web content mining and web usage mining. In this paper discussion is done by explaining the area of Web Mining, its categories and algorithms associated with it. The algorithms discussed are PageRank, SimRank, TF-IDF, k-nearest neighbour, PageGather and CDL4. Then we summarize the algorithms over parameters such as its working, input parameters, complexity and their pros and cons. Also we analyze discussed algorithms over the parameters: relevance, their technique and regression analysis.

In MANET mobile nodes form a temporary network without the use of any existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. Route should be discovered and maintained with a minimum of overhead and bandwidth consumption. A wide range of routing protocols for MANETs has been proposed by researchers to overcome the limitations of wired routing protocols. This paper presents performance evaluation of three different routing protocols, i.e., Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR) and Fisheye State Routing (FSR) in variable pause time. We have used Random Waypoint mobility model and performed simulations by using QualNet version 5.0 Simulator from Scalable Networks. Performance of DSR, OLSR and FSR is evaluated based on Average end to end delay, Packet delivery ratio, Throughput and Average Jitter. Index Terms-MANET, DSR, OLSR, fisheye, random waypoint mobility model, qualnet version 5.0.

Its advancement is fueled by development of tiny low cost sensor nodes which are capable of sensing, processing and transmitting data. Due to the small size of sensor nodes there are various resource constraints. It is the severe energy constraints and the limited computing resources that present the major challenge in converting the vision of WSNs to reality. In this paper, we propose a simple and efficient data compression algorithm which is lossless and particularly suited to the reduced memory and computational resources of a wireless sensor networks node. The proposed data compression algorithm gives good compression ratio for highly correlated data. Simulations for the proposed data compression algorithm are performed on TOSSIM.

In MANET, mobile nodes form a temporary network without using any kind of existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. Route should be discovered and maintained with a minimum of overhead and bandwidth consumption. A wide range of routing protocols for MANETs has been proposed by researchers to overcome the limitations of wired routing protocols. This paper evaluated performance of proactive routing protocol and reactive routing protocol in variable pause time and variable number of nodes. We have used Optimized Link State Routing (OLSR) protocol as proactive routing protocol and Location-Aided Routing Scheme 1 (LAR1) protocol as reactive routing protocol. We have used RWP (random waypoint) mobility model and performed simulations by using QualNet version 5.0 Simulator from Scalable Networks. Performance of OLSR and LAR1 is evaluated based on Average end to end delay, Packet delivery ratio, Throughput and Average Jitter.

Another one, called secondary neurulation (SN), is seen in a posterior region of the body. SN proceeds by mesenchymal-to-epithelial transition (MET), the process contrasting with that of the primary neurulation. Although the SN was histologically described more than 70 years ago, its molecular-and cellular mechanisms remain unknown. SN precursor cells are generated during gastrulation from ingressing cells (mesenchymal) that also give rise to presomitic mesoderm (PSM). This raises two questions: What discriminates SN from PSM? And how mesenchymal cells undergo epithelialization during the SN? To address these questions, we have focused on two transcriptional factors, Pax2 expressed in SN-region and Tbx6L in PSM, to perform tissue-specific gene manipulation using chicken embryos. We have found that Pax2 and Tbx6L play important roles in the formation of SN and PSM, respectively, by counteracting each other. Remarkably, Pax2, when overexpressed in PSM, causes ectopic formation of SN-like neural tube. Furthermore, Tbx6L impedes SN formation when expressed in a presumptive SN. These findings suggest that during the SN processes, Pax2 represses mesodermal genes (i.e. Tbx6L), and regulates a set of genes important for cell epithelialization and tubular formation. We will also discuss a possible link of SN to Hox gene regulation in the construction of posterior body structures.

In MANET mobile nodes forms a temporary network without the use of any existing network infrastructure or centralized administration. A routing protocol is used to find routes between mobile nodes to facilitate communication within the network. The main goal of such an ad hoc network routing protocol is to establish correct and efficient route between a pair of mobile nodes so that messages delivered within the active route timeout interval. Route should be discovered and maintained with a minimum of overhead and bandwidth consumption. This paper presents performance evaluation of three different routing protocols i.e. Ad hoc On-Demand Distance Vector (AODV), Fisheye State Routing (FSR) and Zone Routing Protocol (ZRP) in variable pause times and variable number of nodes. We have used random waypoint mobility model to design the network and performed simulations by using QualNet version 5.0 Simulator [1] from Scalable Networks. Performance of AODV, FSR and ZRP is evaluated based on Average end-to-end delay, Packet delivery ratio, Throughput and Average Jitter.

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes that communicates with each other without using any existing infrastructure or centralized administration. In MANET, due to mobility of nodes network topology changes frequently and thus, routing becomes a challenging task. A variety of routing protocols with varying network conditions are analyzed to find an optimized route from a source to some destination. This paper presents performance comparison of four popular mobile ad-hoc network routing protocols i.e. Landmark Ad-hoc Routing Protocol (LANMAR), Location Aided Routing scheme 1 (LAR1), Dynamic MANET On-Demand (DYMO) and Zone Routing Protocol (ZRP) in variable pause time. We used well known network simulator QualNet 5.0 from scalable networks to evaluate the performance of these protocols. The performance analysis is based on different network metrics such as average jitter, packet delivery ratio, average end-to-end delay and throughput.
