In present DNA microarray technology, the different test-samples are pre-tagged with different kind of fluorescnet tags whose intensity is automatically monitored by a computed software. This software not only captures the signal from the array, but also quantizes the intensity of this signal into a calculated number. This number deciphers the extent of expression levels of the gene to which the fluorphore was attached to. Here, the most crucial step is to detemine where the signal is coming from and if the signal is present or not. Since a microarray contains millions of array data points, it is not possible for normal human eyes to differentiate between two spots based upon their color and intensity. It is not even required ot perform this function manually because millions of data points cannot be quantized by human eye. Thus, the software is initially informed the emission and excitation wavelengths of the fluorophores and thus, the laser equipped in the detection system automatically records and quantizes the signal intensity without minutest involvement of human. Thus, is does not matter if the researcher has normal vision or is a color blind, the data acquisition will be performed solely by the software. Thus it is possible for a person who is colorblind to successfully interpret a microarray scan becuase the data will be quantized into numerical format in the end.

Cognitive radio is an exciting wireless technology that has been introduced for the efficient used of spectrum. Using cognitive radios (CRs), the secondary users (unlicensed users) are allowed to use the spectrum which is originally allocated to primary users (PUs) as far as the active primary users are not using it temporarily. In order to prevent harmful interference to primary users, the SUs need to perform spectrum sensing before transmitting signal over the spectrum. In this paper we use an optimal Bayesian detector for digitally modulated primary user to improve the spectrum utilization, without prior knowledge of transmitted sequence of the primary signals. And further suboptimal detectors in low and high SNR regime. We provide the performance analysis in terms of Detection probability and False alarm probability.

Analysis of the neuronal activities is essential in studying nervous system mechanisms.True interpretation of such mechanisms relies on the detection of the neuronal activities, which appear as action potentials or spikes in recorded neural data. So far several algorithms have been developed for spike detection. In this paper such issue is addressed using entropy measures.Transient events like spikes affect the entropy content of a signal. Thus, a time-dependent entropy framework can be used for spike detection where the entropy of each windowed segment of neural data is computed based on a generalized form of entropy. Detection method is tested on different signal to noise ratios. The results show that the time-dependent entropy method in comparison with available methods enables us to detect spikes in their exact time of occurrence with relatively lower false alarm rate.

The majority visually impaired persons are using a white cane to move within their environment. They avoid to collision the obstacles by detecting objects when swinging white cane touches them. An automatic door is opened when it detects the person comes to it by the sensor, for example, infrared sensor. This kind of automatic doors are very useful because we need not touch the doors in order to open them. However, for majority visually impaired persons, it is difficult to detected automatic doors because they detect the object by touching. In this paper, we propose the detection method which tells the existence of automatic doors to the visually impaired person. The device is consisted of an infrared sensor and a vibration motor. The infrared sensor is put on the tip of the white cane and the vibration motor is put on close to the hand. And when it detects the infrared signal, the vibration motor runs. Then the visually impaired persons can through the automatic door in safety without any cares

Neutrophiols are the host cell fist line defence factors, which act against S. aureus infection (myriad anti -immunity factors). The main immunological inflammatory factors that were involved in his tonsil swelling as follow. The Toll like receptors (TLRs) are signaling receptors, and their activation leading to enhancement of the antimicrobial activity of neutrophils result in the generation of cytokines predominantly by macrophages at the site of infection followed by TLR s activation to present antigen to naïve T cells. This process of macropinocytosis (microbial engulfing) occur through TLRs that induces the dendritic cells maturation finally cell migration.

Part I Identifying Your Customer’s Needs and Goals Chapter 1 Analyzing Business Goals and Constraints Chapter 2 Analyzing Technical Goals and Tradeoffs Chapter 3 Characterizing the Existing Internetwork Chapter 4 Characterizing Network Traffic Chapter 1 Analyzing Business Goals and Constraints This chapter serves as an introduction to the rest of the book by describing top-down network design. The first section explains how to use a systematic, top-down process when designing computer networks for your customers. Depending on your job, your customers might consist of other departments within your company, those to whom you are trying to sell products, or clients of your consulting business. After describing the methodology, this chapter focuses on the first step in top-down network design: analyzing your customer’s business goals. Business goals include the capability to run network applications to meet corporate business objectives, and the need to work within business constraints, such as budgets, limited networking personnel, and tight timeframes. This chapter also covers an important business constraint that some people call the eighth layer of the Open System Interconnection (OSI) reference model: workplace politics. To ensure the success of your network design project, you should gain an understanding of any corporate politics and policies at your customer’s site that could affect your project. The chapter concludes with a checklist to help you determine if you have addressed the business issues in a network design project. Using a Top-Down Network Design Methodology According to Albert Einstein: “The world we’ve made as a result of the level of thinking we have done thus far creates problems that we cannot solve at the same level at which we created them.” To paraphrase Einstein, networking professionals have the ability to create networks that are so complex that when problems arise they can’t be solved using the same sort of thinking that was used to create the networks. Add to this the fact that each upgrade, patch, and modification to a network can also be created using complex and sometimes 4 Top-Down Network Design convoluted thinking, and you soon realize that the result is a network that is hard to understand and troubleshoot. A network created with this complexity often doesn’t perform as well as expected, doesn’t scale as the need for growth arises (as it almost always does), and doesn’t match a customer’s requirements. A solution to this problem is to use a streamlined, systematic methodology in which the network or upgrade is designed in a top-down fashion. Many network design tools and methodologies in use today resemble the “connect-thedots” game that some of us played as children. These tools let you place internetworking devices on a palette and connect them with LAN or WAN media. The problem with this methodology is that it skips the steps of analyzing a customer’s requirements and selecting devices and media based on .

Dirac theorem: For a simple network with n 3 vertices, if each vertex has degree at least n/2 (i.e., ki n/2, i), then the network has a Hamiltonian cycle,. Proof: Let G be the connected graph Let L = (i1,iL) = (i1, i2, . . . , iL) be the longest path. The neighbors of vertex i1 must lie on (i1, iL); the same is true for vertex iL, since if say i is not a neighbour, i i1 i2 ...iiL would be the longest path contradicting our selection of the longest path. The same for iL also. So both i1 and iL are adjacent to vertices in the longest path L only, Since degree of i1>k/2 and i1 is not adjacent to itself, k> n/2 +1 Let us assume a claim There is some value of j (1jk) such that: Incase claim is not true, Since all vertices adjacent to L1 or Lk lie on L, there must be at least deg(L1) vertices on P not adjacent to Lk. Since all the vertices adjacent to Lk and pk itself also lie on P, the path must have at least deg(L1)+deg(Lk)+1n+1 vertices. But L has only n vertices: a contradiction. This gives a cycle C=Lj+1Lj+2…LkLjLj1…L2L1Lj+1. Suppose LC is nonempty. Then since L is connected, there must be a vertex vGC adjacent to some Li. So the path from v to Li and then around C to the vertex adjacent to Li is longer than L, contradicting the definition of L. Hence our assumption/claim is true. Therefore all vertices in L are contained in C, making C a Hamilton cycle.

Border Gateway Protocol (BGP) is the protocol which is used to make core routing decisions on the Internet; it involves a table of IP networks or \"prefixes\" which designate network reach-ability among autonomous systems (AS). BGP is a path vector protocol, or a variant of a Distance-vector routing protocol. BGP does not involve traditional Interior Gateway Protocol (IGP) metrics, but routing decisions are made based on path, network policies, and/or rule-sets. For this reason, it is more appropriately termed a reach-ability protocol rather than routing protocol. BGP was created to replace the Exterior Gateway Protocol (EGP) to allow fully decentralized routing in order to transition from the core ARPAnet model to a decentralized system that included the NSFNET backbone and its associated regional networks. This allowed the Internet to become a truly decentralized system. Since 1994, version four of the BGP has been in use on the Internet. All previous versions are now obsolete. The major enhancement in version 4 was support of Classless Inter-Domain Routing and use of route aggregation to decrease the size of routing tables. Since January 2006, version 4 is codified in RFC 4271, which went through more than 20 drafts based on the earlier RFC 1771 version 4. RFC 4271 version corrected a number of errors, clarified ambiguities and brought the RFC much closer to industry practices. Most Internet service providers must use BGP to establish routing between one another (especially if they are multihomed). Therefore, even though most Internet users do not use it directly, BGP is one of the most important protocols of the Internet. Compare this with Signaling System 7 (SS7), which is the inter-provider core call setup protocol on the PSTN. Very large private IP networks use BGP internally. An example would be the joining of a number of large OSPF (Open Shortest Path First) networks where OSPF by itself would not scale to size. Another reason to use BGP is multihoming a network for better redundancy, either to multiple access points of a single ISP (RFC 1998), or to multiple ISPs.
