O mangal fica muito batido visão da utilização do manguezal pelo pescador e...Daniel S Fernandes
Trata de um estudo parcial sobre a relação entre pescadores extrativistas e o ecossistema de manguezal, a partir do modelo das dinâmicas sociais da comunidade Vila Sorriso, situada a 7,5 km da sede do município de São Caetano de Odivelas/Pa.
MPLS-TP is subset of MPLS. It uses the same data plane as used by MPLS (Defined in RFC 3031 and RFC 3032). MPLS-TP has four major areas:-
1. Data Plane
2. Control Plane
3. O&M
4. Survivability
MPLS-TP has no control plane, the reason for this was that the recovery. If the dynamic control plane is used, in that case the convergence would depend on the dynamic protocol and providers cannot leverage the <50 ms failover time in that case. It uses the same QoS diffserv model except uniform model as used in MPLS.

Dense wavelength division multiplexing (DWDM): A Review Kamal Pradhan
it is clear that as we approach the 21st century the remarkable revolution in information services has
permeated our society. This rapid growth of information technology has led to new services hungry for transmission
capacity. Communication, which in the past was confined to narrowband voice signals, now demands a high quality
visual, audio, and data context for services such as Voice over-Internet protocol (VoIP), video streaming,
broadcasting of TV programmes, high-speed file sharing, E-commerce and E-Governance need a transmission
medium with very high bandwidth capabilities for handling vast amounts of information. The telecommunications
industry, however, is struggling to keep pace with these changes. Earlier predictions were made that current fiber
capacities would be adequate for our needs into the next century but they have been proven wrong but these fiber-
optics, with its comparatively infinite bandwidth and by employing the latest multiplexing technique, i.e. Dense
Wavelength Division Multiplexing (DWDM) has proven to be the solution.
PERFORMANCE ANALYSIS OF ULTRAWIDEBAND WDM-ROF TECHNIQUEIAEME Publication
The demand for high capacity and wideband telecommunication channels for longdistance communication increases exponentially. The standard C and L bands have limited bandwidth and capacity. That promotes intensive research and development in wideband wavelength division multiplexing, intending to achieve low BER and highquality factors. We used four channels from various bands in the proposed wideband WDM method: O (1355 nm), E (1427 nm), L (1595 nm), and U (1595 nm) (1665 nm). We adjusted the laser intensity from -10 to 10 dBm and the optical fiber length from 20 to 80 km for the wideband WDM performance analysis. Raman preamplifiers and FBG have been incorporated into the receiver to improve the quality factor and BER of the received signal. This study established 40 Gbps data transmission over a unique ultrawideband of 310 nm. The Q factor and BER for the four channels are 7.345; 19.949; 7.831; 5.486 and 1.006e-13; 7.281e-89; 2.395e-15; 2.038e-08 at a laser power of -5 dBm/80km, respectively. The proposed technique is simulated and analyzed using optical simulation software Optisystem 13.

The Effect of PMD (Polarization Mode Dispersion) the Fibers of New and Old In...inventionjournals
This is a study conducted in a laboratory at the university as a simulation to see the effect of new fiber PMD for different distances. This is done to compare the performance of the digital system with optical fiber WDM. In this simulation are not included remission, chromatic dispersion and nonlinear effects. In this way all of the signal distortions caused only by different combinations of PDM. Polarization effects are very important in communications systems with optical fiber. Optical fiber that is used mainly during the simulation is a standard single mode fiber (SSMF).
Memristor-Capacitor Based Startup Circuit for Voltage Reference Generatorsmangal das
This paper presents the design of Memristorcapacitor based startup circuit. Memristor is a novel device and has many advantages over conventional CMOS devices such as no leakage current and is easy to manufacture. In this work the switching characteristics of memristor is utilized. First the
theoretical equations describing the switching behavior of memristor are derived. To prove the switching capabilities of Memristor, a startup circuit based on series combination of Memristor-capacitor is proposed. This circuit is compared with the reference circuit (which utilizes resistor in place of memristor) and the previously reported MOSFET based startup circuits. Comparison of different circuits was done to validate the results. Simulation results shows that memristor based circuit attains on (I = 2.25 mA) to off state (I = 10 μA) in 2.8 ns while the MOSFET based startup circuits takes (I = 1 mA) to off state (I = 10 μA) in 55.56 ns. However no significant difference in switching time was observed when compared with resistance based startup circuit. The benefit comes in terms of area because much larger die area is required for manufacturing of resistance in comparison to fabrication of memristor.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
