Dr. Parteek Bhatia is Associate Professor in the Department of Computer Science and Engineering and Former Associate Dean of Student Affairs at Thapar Institute of Engineering and Technology, Patiala. He has research interest in area of NLP, Machine Learning and Assistive Technologies. If the (i; j)-th entry of the matrix is k, it means at that time the station i has k packets for transmission to station j. Count the number of nodes at given level in a tree using BFS. You can change your ad preferences anytime.  Conditional, Looping and Sequential Statements. We use an array maxR[0..N-1] that stores the senders assigned to different receivers. He is PhD title is “UNL Based Machine Translation System for Punjabi Language”. Learn more. If a receiver is assigned to somebody else say x, then we recursively check whether x can be assigned some other receiver. He has handled research projects of more than one crore rupees sponsored by International and National funding agencies. He has more than twenty years of academic experience, including six years at D.A.V College Amritsar. He is also running his YouTube Channel “Parteek Bhatia: Simplifying Computer Education” for sharing video sessions on Machine Learning, Big Data, DBMS, SQL, PL/SQL and NoSQL. One main issue in cellular system design reduces to one of economics. In a fixed channel assignment strategy, each cell is allocated a predetermined set of voice channel. If x can get other receiver, we change the sender for receiver ‘v’ and return true. Contributed by John S. Davis, II, U.C. Extra space can be reduced and code can be simplified using the fact that the graph is bipartite. |V| since there can be only |V| possible edges coming out from source node. There must be a source and sink in a flow network. A variation is the borrowing strategy. If bmp() returns true, then it means that there is an augmenting path in flow network and 1 unit of flow is added to the result in maxBPM(). Let us first define input and output forms. We use Ford-Fulkerson algorithm to find the maximum flow in the flow network built in step 1. Looks like you’ve clipped this slide to already.

He is a author of popular books like “Simplified Approach to DBMS”, “Simplified Approach to Visual Basic” and “Simplified Approach to Oracle” and “NoSQL in a Day”. For every receiver we try, we do following: Channel Assignment Strategies • With the rapid increase in number of mobile users, the mobile service providers had to follow strategies which ensure the eﬀective utilization of the limited radio spectrum. Particularly as to how calls are managed, when a mobile user is handed off from one cell to another.

If a receiver is not assigned to anybody, we simply assign it to the sender and return true. APIdays Paris 2019 - Innovation @ scale, APIs as Digital Factories' New Machi...
