The routing and wavelength assignment problem is a significant problem faced in any optical network. This problem is a significant problem faced in any optical network. This problem can be solved by splitting it into two problems. First, the routing problem is tackled and an optimal routing network is obtained. After this, the wavelength assignment problem is tackled and the right wavelengths are chosen for each path. In this paper, we look into two shortest path first routing algorithms, namely Dijkstra’s algorithm and the Genetic Approach algorithm and compares the results. Two wavelength assignment algorithms, random fit algorithm and first fit algorithm are compared and the results are tabulated. All simulations and results are observed on MATLAB and Python.

The Indian Regional Navigation Satellite System (IRNSS), also known as NavIC- Navigation with Indian Constellation provides real time positioning and timing services. The NavIC receivers provide information related to both satellite and receiver. There are multiple algorithms which can be used for position estimations. In this paper, Iterative Least Squares and Extended Kalman Filter algorithms are proposed to estimate the unknown receiver position by taking clock bias of the receiver into consideration.

In this work, we present a multi-scale modelling technique using a signal adapted multirate filter bank. Unlike the existing multi-resolution modelling strategies, the proposed algorithm can be implemented using a signal adaptive, fast, recursive algorithm which is computationally efficient. The analysis filter bank, used in this work is a multivariate whitening filter whose outputs are orthogonal in time as well as across channels. The analysis filter bank whitens the input signal in different spectral bands. The synthesis filter bank, proposed here, has been designed to reconstruct only the given signal and not every energy signal, as is done in the perfect reconstruction filter bank case. Outputs of the M-synthesis filters, thus, provide the required M-orthogonal sub-band constituents of the given signal. Since the proposed modelling scheme is signal dependent it can be efficient used for applications like energy compaction, dimension reduction etc. The performance of the proposed algorithm does not deteriorate for long data and, also, the number of sub-bands is not arbitrary. The efficacy of the algorithm has been verified via simulation studies.

to improve security and performance in the networks most of the enterprises deploy middlebox processing services. But these infrastructures are expensive, prone to failures and complex to manage. Hence it can be argued that middlebox can have a better performance in a cloud platform. It is challenging to have an implementation which is functionally equivalent to the traditional middlebox deployments. This paper will discuss, what a middlebox is, introduction to frequently used middleboxes, recent trends in middlebox, and challenges faced by these middleboxes.

Usability Engineering is one of the domain areas that falls under the concepts of Human-Computer Interaction. The aim is to achieve systems that are efficient with respect to user experience. A combination of various approaches can be implemented at the disparate levels of the design and development procedure in order to obtain the necessary metric of usability efficiency. A structured and systematic approach aids in giving the designer information on the improvement of an interface. Some of the approaches that have been adopted for this purpose have been discussed here.

Alzh-care is an Alzheimer patients assistive system. This system assists the patients by recognizing their intention on the activity and guides them to the completion of that task. It helps the patients in completing their day-today tasks by recognizing their intent of the task at the early stage. In this work, Intention recognition is achieved through the sensor based activity recognition process. These kinds of systems have far reaching applications in the domains like assisted living; healthcare monitoring and they offer lots of open challenges to solve in the arena of research and development.This paper discusses the implementation of the Alzh-care assistive system using sensors for the day-to-day activities like eating meals and taking medicines etc., We have used knowledge driven approach for representing the domain knowledge on the day-to-day activities is as ontology. This in turn is referred to know the intentions of the patients and voice assist them in completing the intended task. We have tried state machine approach to infer and assist on the task. Knowledge driven approach has proven to perform better than the data driven approaches as the latter suffers from the cold start and reliability issues.We have tabulated the trials and noted the success rate of recognition of the intent for each of the activity experimented. This system is proven to be 85% to 90% accurate for predicting the intentions in the finite disambiguous tasks, owing the other 5% to 10% of the failure caused by the sensors used.

Ryu and Floodlight controllers are being used in academia and industries for different research and development purposes. The objective of this paper is to compare the performance of these controllers under different topologies namely single, linear, tree, torus and custom. Experiments are performed under a much known emulator, mininet. Four parameters were valuated under this experimental setups namely throughput, jitter, latency and packet loss. Valuation of results clearly shows that Ryu is giving better throughput as compared to Floodlight in all the topologies. In case of latency and jitter Ryu is performing better in all the topologies except Torus. Similar is the case with packet loss.

Machine learning is an application of artificial intelligence based on the theory that machines can learn from data, discern patterns and make decisions with negligible human intervention. With today’s world being inundated by data, machine learning is very relevant due to the amount of learning potential. Machine learning caters to a variety of applications including image recognition, speech recognition, weather prediction, portfolio optimization and so on. The Forex Exchange is a market that allows traders and investors to buy, sell and exchange currencies of various nations. It is regarded as the largest financial market with over 5 trillion American dollars in daily trades, which is larger than the equity and futures markets combined. The Commodity market is a market that allows buying, selling and exchanging of raw materials or primary products. Using the concept of machine learning, this project aims to develop and introduce an agent to automate the trade of a given commodity or currency in a simulated market with the objectives of maximizing returns and minimizing losses for the trader. The model learns from trends in historical market data and is capable of buying, selling or holding a trade at a given instance. The model is validated by running the agent on unseen market data of a later period and the returns generated are analyzed.

The uniqueness of multilevel inverters is such that they have a structure which makes it possible to reach high voltages with less harmonic content. This paper gives a comparison between a seven level and nine-level inverter with reverse voltage Topology which drives Resistive load and Single Phase Induction Motor with Sinusoidal Pulse Width Modulation Scheme (SPWM).The number of components used in this topology are less compared to the existing high level inverter topologies. With lower Total Harmonic Distortion (THD) there will be less stress on the power switches and higher efficiency of the circuit. The performance analysis is based on the results of stimulation study conducted on the operation of the multilevel inverters using MATLAB/ SIMULINK.

One of the key factors to be looked at during design of an automated eye screening system is to find the optic disc and optic cup. Objective: In eye screening of diabetic patients, the feature such as hard exudates and cotton wool spots can be noticed which share similar properties with optic disc In certain diseases like glaucoma ophthalmologist look at the ratio of optic cup with optic disc to detect the presence or absence of glaucoma Currently, the process is manual performed by ophthalmologist, which a time consuming and tedious job. This fact motivated to design a fully automated procedure to detect optic cup and optic disc. Method: In the current paper a multilevel active contour technique is used that generates the snake to detect boundaries of optic cup and optic disc using intensity of the border pixels which are tested using 3σ control limits. The algorithm works in two parts. In part-1, optic disc boundary is detected and in part-2, the optic cup is marked by concentrating inside the area marked as optic disc in part-1. Findings: This approach reduces processing area and hence improves computational time A local database to carry out this work was created by collecting images from Karnataka Institute of Diabetology, Bangalore The results obtained by the proposed procedure are encouraging and have yielded 100% results with the fundus images containing full optic disc Improvement: The method is fully automatic and no user intervention is required
