Low power VLSI design has become an important discipline due to increasing device densities, operating frequencies, and proliferation of portable electronics. Power dissipation, which was previously neglected, is now a primary design constraint. There are several sources of power dissipation in CMOS circuits, including switching power due to charging and discharging capacitances, short-circuit power during signal transitions, and leakage power from subthreshold and gate leakage currents. Designers have some control over power consumption by optimizing factors such as activity levels, clock frequency, supply voltage, transistor sizing and architecture.Polytronics

Light Trees pptPrashant Chaudhari
油
The concept of a light-tree is introduced in a wavelength-routed optical network. A light-tree is a point-to-multipoint generalization of a lightpath. A lightpath is a point-to-point all-optical wavelength channel connecting a transmitter at a source node to a receiver at a destination node. Lightpath communication can significantly reduce the number of hops (or lightpaths) a packet has to traverse; and this reduction can, in turn, significantly improve the networks throughput. We extend the lightpath concept by incorporating an optical multicasting capability at the routing nodes in order to increase the logical connectivity of the network and further decrease its hop distance. We refer to such a point-to-multipoint extension as a light-tree. wireless Communication Underwater(Ocean)

Underwater wireless communication uses acoustic signals to transmit digital information through water. Wired connections are not always feasible for underwater experiments due to problems like cable breaks or high costs. Acoustic communication is affected by factors like path loss, noise, multipath propagation, and Doppler spread. Advanced acoustic modems employ techniques like error correction coding to achieve low bit error rates. Underwater acoustic sensor networks use groups of sensors and autonomous underwater vehicles linked by acoustic connections to collaboratively monitor things like pollution, currents, and equipment. Despite progress, limitations remain regarding battery life, bandwidth, and environmental impacts on performance.Plasma ANTENNA ppt

It then describes the key aspects of the OSI reference model, which divides communication problems into seven layers - physical, data link, network, transport, session, presentation and application layer. The OSI model was created in 1984 and became an international standard to ensure greater network compatibility.1 introduction

The document provides an overview of computer networks and the Internet from multiple perspectives:
1) It describes the "nuts and bolts" view of the Internet as millions of connected devices communicating over physical links using packet switching and protocols.
2) It outlines a "service view" of the Internet as infrastructure providing services to applications like the web and email.
3) It introduces the concept of network protocols that govern all communication and defines common protocols like TCP and IP.Network essentials chapter 3

A network connects devices that exchange data over media. A host has a logical network address and can be devices like workstations, servers, printers. Protocols are agreed upon rules for network functions. The network topology refers to the physical layout, such as bus, star, or ring. Networks are LANs for small areas or WANs connecting multiple LANs over wide areas. Devices include routers, switches, bridges, firewalls, and more.Reference models in Networks: OSI & TCP/IP

The document discusses reference models and the OSI reference model. It provides details on:
- The need for a reference model to standardize network components and layer functions to promote interoperability.
- The OSI reference model, approved in 1984, which divides communication problems into seven layers to aid in network interconnection.
- Each of the seven layers of the OSI model, describing their functions and responsibilities for moving data through the network.Skr+3200+chapter+2+(kweh)

The document discusses the OSI model and TCP/IP model for computer networking. It describes the seven layers of the OSI model including the physical, data link, network, transport, session, presentation and application layers. It provides details on the functions and responsibilities of each layer. The document also summarizes that the TCP/IP model has five layers and combines the top three layers of the OSI model into one layer.What is network architecture

Floating Offshore Wind in the Celtic Seapermagoveu
油
Floating offshore wind (FLOW) governance arrangements in the Celtic Sea case are changing and innovating in response to different drivers including domestic political priorities (e.g. net-zero, decarbonization, economic growth) and external shocks that emphasize the need for energy security (e.g. the war in Ukraine).
To date, the rules of the game that guide floating wind in the UK have evolved organically rather than being designed with intent, which has created policy incoherence and fragmented governance arrangements. Despite this fragmentation, the UK has a well-established offshore wind sector and is positioning itself to become a global leader in floating wind.
Marine governance arrangements are in a state of flux as new actors, resources, and rules of the game are being introduced to deliver on this aspiration. However, the absence of a clear roadmap to deliver on ambitious floating wind targets by 2030 creates uncertainty for investors, reduces the likelihood that a new floating wind sector will deliver economic and social value to the UK, and risks further misalignment between climate and nature goals.

Coordinate Rotation Digital Computer (CORDIC) discovered by Jack E Volder. It is a shift-add operation and iterative algorithm. CORDIC algorithm has wide area for several applications like digital signal processing, biomedical processing, image processing, radar signal processing, 8087 math coprocessor, the HP-35 calculator, Discrete Fourier, Discrete Hartley and Chirp-Z transforms, filtering, robotics, real time navigational system and also in communication systems. In this paper, we discussed about the CORDIC algorithm and CORDIC algorithm based finite impulse response low pass & high pass filter. We have generated the M-code for the CORDIC Algorithm and CORDIC Algorithm based FIR filter with the help of MATLAB 2010a.We also discussed about the frequency response characteristics of FIR filter.
