Notebook-based AI Pipelines with Elyra and Kubeflow
A typical machine learning pipeline begins as a series of preprocessing steps followed by experimentation, optimization and model-tuning, and, finally deployment. Jupyter notebooks have become a hugely popular tool for data scientists and other machine learning practitioners to explore and experiment as part of this workflow, due to the flexibility and interactivity they provide. However, with notebooks it is often a challenge to move from the experimentation phase to creating a robust, modular and production-grade end-to-end AI pipeline.
Elyra is a set of open-source, AI centric extensions to JupyterLab. Elyra provides a visual editor for building notebook-based pipelines that simplifies the conversion of multiple notebooks into batch jobs or workflows. These workflows can be executed both locally (during the experimentation phase) and on Kubernetes via Kubeflow Pipelines for production deployment. In this way, Elyra combines the flexibility and ease-of-use of notebooks and JupyterLab, with the production-grade qualities of Kubeflow (and in future potentially other Kubernetes-based orchestration platforms).
In this talk I introduce Elyra and its capabilities, then give a deep dive of Elyra's pipeline editor and the underlying pipeline execution mechanics, showing a demo of using Elyra to construct an end-to-end analytics and machine learning pipeline. I will also explore how to integrate and scale out model-tuning as well as deployment via Kubeflow Serving.

Why Ipv6 May Be Adopted Later Rather Than Sooner
This document discusses the transition from IPv4 to IPv6, comparing the key differences between the two protocols. IPv6 was developed to address limitations in IPv4, such as the limited number of available IPv4 addresses. Some of the improvements IPv6 offers over IPv4 include a larger address space, built-in security features, easier configuration, and support for new applications and technologies. While IPv6 is meant to eventually replace IPv4, a full transition will take time, and both protocols will coexist during the transition period.
Ipv4 To Ipv6 Transition
The document discusses the need to redesign the routing and addressing architecture of the Internet as identified by the Internet Architecture Board due to concerns over the scalability of today's routing system and the impending exhaustion of IPv4 addresses. It focuses on proposals to resolve these issues that are based on a common philosophy of separating location and identity in addressing, called the 'Loc/ID split'. The article will focus on achieving consensus on an addressing method that incorporates location.

In aqueous solution, Cd2+will precipitate out of solution in the form of CdS in the presence of
hydrogen sulfide (H2S). The Ksp of CdS = 1.0 x 10-28 and Ksp of H2S = 1.0 x 10-26 for the
reaction: H2S (aq) = 2 H+(aq) + S2-(aq)
a. Write the balanced net ionic equation for the reaction of cadmium ion with hydrogen sulfide
to form cadmium sulfide solid.
b. Write the equilibrium expression for the equation in part a.
c. Calculate Koverall for the reaction in part a.
d. Calculate the [Cd2+] in a solution saturated with H2S (0.10 M) at a pH = 2.00 ([H+] = 0.010
M).
Solution
a) The balanced ionic equation for the formation of cadmium sulfide from cadmium ion and
hydrogen sulfide is given as
Cd2+ (aq) + H2S (aq) <=======> CdS (s) + 2 H+ (aq) ……..(1)
b) The equilibrium constant for the reaction is given as
Koverall = [H+]2/[Cd2+][H2S] (ans)
Note that the concentration of a solid is not written in the expression for the equilibrium
constant.
c) Write down the two ionization reactions as below.
CdS (s) <=======> Cd2+ (aq) + S2- (aq) ……..(2)
Ksp = [Cd2+][S2-]
H2S (aq) <=======> 2 H+ (aq) + S2- (aq) …….(3)
Ka = [H+]2[S2-]/[H2S]
Subtract (2) from (3) and obtain
Cd2+ (aq) + H2S (aq) <======> CdS (s) + 2 H+ (aq)
Koverall = [H+]2/[Cd2+][H2S] = ([H+]2/[H2S])*(1/[Cd2+])
= ([H+]2[S2-]/[H2S])*1/([Cd2+][S2-]
= Ka*1/Ksp
= (1.0*10-26)*1/(1.0*10-28) = 100 (ans).
d) We have [H2S] = 0.10 M and pH = 2.00.
We define pH as pH = -log [H+]
====> 2.00 = -log [H+]
====> [H+] = antilog (-2.00) = 0.01 M
Since Ka (H2S) is extremely small, we may assume the equilibrium concentration of H2S to be
equal to 0.10 M; hence, we have
Koverall = [H+]2/[Cd2+][H2S]
====> 100 = (0.01)2/[Cd2+].(0.10)
====> [Cd2+] = (0.01)2/(100*0.10) = 1.0*10-5
The concentration of Cd2+ at equilibrium is 1.0*10-5 M (ans)..

Introduction
Internet Protocol from 6 (IPv6) is the late conformity of the Internet convention and the fundamental model of the convention will be thoroughly utilized. IPv6 is genuinely a new drawing nearer closer tradition made to join all the possible needs associated with prospective web that apparent as Internet shape 2. This convention has its herald IPv4, limits for the framework level .3. In addition to their giving of a huge amount of sensible location region, this protocol offers sufficient attributes to address the disadvantage of IPv4.
As of recently, IPv4 has confirmed independent from anyone else like a capable routable tending to convention and offered every one of us for a long time upon their best-exertion conveyance framework. It had been produced in the before 80s and would not acquire any imperative alteration later. Amid the season of their introduction to the world web has been confined essentially to some instructive establishments for their examination and to the division of assurance. Alongside IPv4's location zone weakness, IPv6 is as of now tackling the administration or supervision of web, which is some of the time called Internet form 2. On June 06, 2012 the web organization formally discharged IPv6. Today numerous ISPs have been giving IPv6 upon open site and need to keep up this executed. Each of the device makers likewise partook to give IPv6 naturally permitted on items. This is a stage to persuade web organization to move to IPv6.
IPv6 Variations
· By completing this new tradition the area degrees get extended, which can help to convey plus or minus three hundred and forty trillion stand-out IP addresses.
· To grow the guiding efficiency the header is more made strides.
· Extension and decisions support are fused to engage all around sorted out sending.
· Also develop the affirmation and payload embodiment.
Why is IPv6 Required?
As everyone is careful that the IPv4 convention is missing the mark on its area space. Since one another day over the world, there is an augmentation in the use of PC's, mobile phones, tablets, gaming structures, and diverse machines which expected to join with the web. With its 128-bit area position, IPv6 can reinforce 3.4 x 1038 or 341,283,365,92,1938,464,465,372,608,432,764,212,459 novel IP addresses. Moreover, differentiating and the IPv4 convention the area range is adequately broad to plan an intriguing area on every contraption.
Impact of Migrating to IPv6
The move has begun in perspective of the essential and the requirement for improvement of area space for inevitable applications. Fig.2 identifies with the development-organizing model. Early on step is to get ready for IPv6 to ensure business movement. Game plan step should be all that much organized, so that layout and assembling doesn't end up being pointlessl ...

Introduction
Across all types and sizes of organizations, the Internet and networks have changed the way
that business is conducted. Twenty years ago, computers were glorified typewriters that could
not communicate with one another. If we wanted to communicate we used the telephone.
Today computers constantly exchange data with each other over distance and time to provide
companies with a number of significant advantages. The convergence of access technologies,
cloud, 5G networks, multitasking mobile operating systems, and collaboration platforms con-
tinues to change the nature of work, the way we do business, how machines interact, and other
things not yet imagined. In this chapter you will learn about the different types of networks,
how they affect the way that businesses communicate with customers, vendors, and other
businesses, and how the largest network, the Internet, is enabling massive automatic data col-
lection efforts from “things” rather than from people.

Sony Builds an IPv6 Network to Fortify
Competitive Edge
Sony’s Rapid Business Growth
In the early 2000s, Sony Corporation had been engaged in strate-
gic mergers and acquisitions to strengthen itself against intensifying
competition (Figure 4.1). By 2007 Sony’s enterprise network (internal
network) had become too complex and was incapable of supporting
communication, operations, and further business growth (Table 4.1).
The enterprise network was based on IPv4. A serious limitation was
that the IPv4 network could not provide real-time collaboration among
business units and group companies.
Expansion efforts were taking too long because of the compl ...

Abstract
In today's world as technology is growing people are looking to adopt new technologies which offer them a feasible and easy access to the resources with a security that makes them away from common threats. This paper introduces the introduction to the internet protocols and concept of the IPV4 and IPV6, as well what are the disadvantages in the IPV4 and the advantages in IPV6. This paper describes the future concepts of the IPV6 and the future impact of the IPV6 on the network field by describing a brief history of the internet protocols and the statistical representation of the IPV6 users.
Introduction
Transport layer is the basic layer in the OSI and the TCP/IP model. The basic task of this layer is to send or receive the data or voice and video data grams or packets over the internet. IPV 4 is meant for Internet Protocol version 4. The network protocol that has been used in the Internet since its inception is IPv4 , which provides 2^32 distinct addresses. Its successor IPv6(Internet Protocol Version 6) provides 2^128 addresses, but IPv6 adoption has not proceeded as quickly as its designers expected (Erik Kline,2011). The main need for the migration to IPV6 from IPV4 is mainly for the ip addresses . IPv4 provides approximately 4.3 billion of ip addresses but there is a need for more ip addresses. For that reason they introduced IPV6.
History
The current trend of the Internet Protocol IPv4 was initially grown in the 1970s, and the primary convention standard RFC 791 that administers IPv4 usefulness was distributed in 1981. With the remarkable extension of Internet use - particularly by highly populated nations like India and China. The approaching deficiency of loca ...

Cmos Sensor
This document discusses the design of an active CMOS sensor array for electrochemical biomolecular detection. The sensor array allows for highly parallel analysis by miniaturizing the sensing platform and enabling multiple working electrodes on a single chip. Each sensor contains a gold working electrode that can detect changes from DNA hybridization through electrochemical techniques like cyclic voltammetry and potentiostat control circuits. While CMOS sensors provide advantages of reduced size and complexity, limitations include lack of suitable electrode materials and voltage compatibility with standard CMOS ICs.
Wind Turbine
This document outlines a major project to design a vertical wind turbine as a renewable energy source. It discusses the objectives of applying theoretical knowledge practically and the advantages of vertical wind turbines over horizontal axis wind turbines, namely that they can harness wind from any direction and are easier and less costly to build. The estimated cost for the vertical axis wind turbine project is Rs. 2000,000 to Rs. 3000,000.
Wind Mill
The document discusses the basic requirements and design considerations for running a wind mill. It notes that atmospheric pressure should be 8.5 bar and efficiency increases 100% for every 10 meters in height. Blades should be airfoil shaped and made of materials like NACA 44 or 63 to withstand all weather conditions. Running wind mills faces challenges of being unpredictable, intermittent, and occupying large areas for power production. Materials used include aluminum sheets, hub, main shaft, bearings, gearbox, generator, and worm gears. A model demonstrates how moving air contains kinetic energy that can be calculated and converted to power.
Wimax
This document summarizes a seminar presentation on proposing an adaptive bandwidth request scheduler for real-time polling service (rtPS) in WiMax networks. The proposed scheduler aims to estimate data arrival rates and calculate adaptive time slot allocations to address problems in the standard rtPS scheduler, such as requests made before grants are received. Analysis shows the adaptive scheduler reduces average queue lengths and delays compared to conventional scheduling. In conclusion, the adaptive approach requires smaller buffers and decreases delays significantly for rtPS traffic.
Virtual Private Network
A dynamic virtual private network (DVPN) allows secure connections between remote users and private networks through virtual connections over public networks like the internet. It provides enhanced security, can accommodate changing user communities dynamically, and maintains integrity over user access rights and data security over time regardless of technological changes. Key features include distributed access control, application independence, access control based on authenticated user identities, and support for user groups. DVPNs establish trust in open network environments through flexible yet finely-controlled security.

It describes synchronization circuit-based dual photocells that improve measurement stability and repeatability. Position sensitive detectors are discussed that can measure the position of a light spot in one or two dimensions on a sensor surface to acquire high-resolution 3D images. A proposed sensor architecture combines color and range sensing for applications like hand-held 3D cameras.
Iptv
IPTV provides television services over IP networks. It has several key components, including video encoders, video servers, middleware, conditional access systems, and set-top boxes. Video is encoded and transmitted over the network in IP packets. IPTV allows for features like video on demand and a better quality of service than internet TV. While it provides benefits like interactivity and switched digital channels, IPTV also faces challenges like packet loss and limited support for high-definition content. It has applications for distance education, electronic government, and corporate training in addition to television and entertainment. IPTV is expected to grow as networks converge, but still needs widespread adoption in India.
Holography
Holography is a technique that uses the properties of light interference and diffraction to record three-dimensional information of an object. The document discusses the history and principles of holography, how holograms are constructed and reconstructed, different types of holograms and their applications in microscopy, interferometry and more. Holography allows the recording and reconstruction of three-dimensional images from a two-dimensional surface, providing depth perception and parallax.
Foult Tolerence In Distributed System
Distributed systems use multiple autonomous computers that communicate via messages to improve processing throughput, allow for CPU specialization, and provide fault tolerance. Faults in distributed systems can include data corruption, hanging processes, misleading return values, hardware/software/network outages, and resource overcommitment. To provide fault tolerance, processes are replicated across multiple computers so the system can continue functioning even if some processes fail. There are different types of faults like crash faults, omission faults, and Byzantine faults. Recovery from failures can use backward or forward recovery approaches.
Hydraulic Ram
A hydraulic ram is a simple water pump powered by hydropower that takes water at one pressure and flow rate and outputs it at a higher pressure and lower flow rate. It has two moving parts - a waste valve and delivery check valve. Water flows through an inlet drive pipe until it closes the waste valve, creating pressure to open the delivery check valve and pump some water to the outlet delivery pipe at a higher elevation than the source. The pressure vessel cushions pressure fluctuations and improves efficiency. Properly designed, a hydraulic ram can pump water with 60-80% efficiency using only the force of flowing water.
Implementation Of Bss And Nss In Mobile Communication
The document discusses the Base Station Subsystem (BSS) and Network and Switching Subsystem (NSS) in mobile communications. The BSS connects the mobile station to the NSS and consists of the Base Transceiver Station (BTS) and Base Station Controller (BSC). The NSS includes the Mobile services Switching Center (MSC), Home Location Register (HLR), and Visitor Location Register (VLR). Together, the BSS and NSS provide critical functions such as mobility management, call control, and short message services that enable mobile communication.
Smart Cards
This document discusses smart cards, which are plastic cards with embedded integrated circuits that can securely store and process data. Smart cards use security mechanisms like passwords, cryptographic challenges, and biometrics to authenticate users and verify the identity of terminals. The document outlines the components of smart cards like memory, processors, and card readers. It also describes common applications of smart cards like banking, ID verification, and wireless communications. The goal of the project discussed is to define a standard set of commands for smart cards to enable their use in Indian applications.
Jini
JINI is a distributed system architecture developed by Sun Microsystems that allows devices to dynamically join and detach from a network without configuration. It provides code mobility, is protocol agnostic by using Java interfaces, and enables leasing for network robustness and self-healing. The JINI architecture consists of services that can be discovered by clients using a lookup service. Services register with the lookup service and clients use proxies returned by the lookup service to directly invoke methods on services.
Fluorescent Multi-Layer Disc
Fluorescent multi-layer disc (FMD) is a new optical data storage technology that stores digital data in three dimensions across multiple layers, similar in size to CDs and DVDs but with much higher storage capacity of up to 50GB+. FMD works on the phenomenon of photochromism to obtain fluorescent properties from the fluorescent material used and allows for parallel reading and writing across layers at speeds of up to 1GB/sec. FMD provides advantages over traditional optical discs like CDs and DVDs such as greater storage capacity, faster access, and compatibility with existing formats while avoiding the interference issues of coherent light used in other technologies.
Manet
This document summarizes a seminar presentation on Mobile Ad-Hoc Networks (MANETs). It introduces MANETs as networks without infrastructure where nodes can connect in dynamic and flexible topologies. It discusses routing challenges in MANETs due to the dynamic topology. It also summarizes several routing protocols used in MANETs like DSR, DSDV, CGSR, ABR and SSR, which aim to establish and maintain routes between nodes that are moving. Finally, it discusses security and performance issues in MANETs and proposes the dynamic virtual backbone approach to abstract node mobility.
Optical Fibre Detector
