We all know that fertilizer increase the OM growth but the application of fertilizer have a great role in this mechanism.. myself Udit want to know about the fertilizer application method and OM content in soil.
I am looking for research idea in Satellite Communication systems for my master research. I work in Broadcasting. Your good suggestions will be highly valued. Thank you
I am going to investigate the electric field strength in broadcast station due to some complain concerning the health situation of the employees.
Thank to everyone that can help.
Without using triangulation, how might one broadcast a signal that would only be picked up by one antenna out of the many present? Or, if not one antenna, then perhaps just a few close by. These antenna are not stationary. We can use any frequency that we want, although a higher frequency would be best. Each antenna has a slightly different Q, length, and width.
Today news over entire world is ready at fingertip. Also it creates lot of junk news which one may not interested at all. Is there any system developed to fetch only the important happenings and broadcast as online FM station (a automated FM station). How design such automated FM station to which can collected information from various online news channels and broadcast only important news as audio based on predefined categories of news. Is possible to develop mobile app for such application?
The approach should meet technical criteria, application in sports marketing, and include all the complementarity of the sports system.
DVB= digital video broadcasting
the software can be a Matlab/simulink implementation or a stand alone software
i have gathered TV signal from the air and now i need a software that can convert this signal to video.
thanks for your time.
I want to find secrecy rate of a main channel in case of Gaussian broadcast channel. e.g. I have a single transmitter and a receiver where eavesdropper wants to eavesdrop the communication over secondary channel. What will be the information rate, so eavesdropper can be kept ignorant of sent message
I am not a speaker of Spanish, but I teach media and am wondering about the dialect or accent of Spanish used in Spanish language media across the United States.
Is it based on the version of Spanish spoken in the region where the media outlet exists? Is there an overall preferred accent (like Midwest English is the preferred American English accent)?
What form of Spanish should a "Spanish Media" academic program in the US teach?
Hi, I am working as farm broadcaster. I am doing research on impact of my farm broadcast's on farmers in my area. I would also like to measure its impact in developing agriculture and rural economy in my program covering zone. I would like to know if any one is doing similar kind of research or know about such media research works can guide me please.
is it same or different for all three? if it differs then how to calculate energy dissipation for unicast, multicast, and broadcast at the same distance?
Scenario: Cluster based wireless sensor network.
I am using CCNx Protocol implemented in Contiki OS. Details of this implementation are available in the given link. And source code for this protocol is also given in attachment. In this protocol, broadcast mode is implemented. I want to use this protocol in multicast or unicast mode. Whats changes will be required. Code for broadcast mode is given in ccn_driver.c file which is present in this folder contiki/core/net/ccn.
Your advantageous and valuable help is required.
while using third order program to generate third order force constant, I am getting this error. help me to get out of it. I have used a 3X3 supercell for a monolayer
I have a question in NS2 . I am simulating a Vanet scenario where there is a group of vehicles in topology of 1 km * 1 km. There is one leader vehicle among them that should broadcasts a packet to all the vehicles and all other vehicles should reply back. Of course there are some vehicles that will be far from the transmission range of the leader. How the packets sent from the leader will reach the other vehicles and vice versa?.
In RPL (Routing Protocol for Low Power and Lossy Networks), to maintain a DAG (Directed Acyclic Graphs), each node periodically generates DIO messages triggered by the trickle timer.
If the rank value of a node has changed after recalculation (due to update of ETX after data transmission), does the node issue a DIO message to broadcast the updated rank immediately or waiting for the trickle timer?
hai every one, i have one doubt, with FM broadcast signals i started modeling the passive bistatic radar, where i received one signal from target(echo signal,moving target with constant velocity), another signal from direct path(called reference signal) these two signals were correlated and got some peak(s), now my problem is how can i prepare threshold and how can i detect the target,
I have a question regarding the signals broadcast by nodes in VANET. I wanted to know when a node broadcasts a signal to the medium is it always with same power. Like does the node just take the maximum interference range and broadcasts. Or does it vary in every case.
I simulated the case of keeping static receiver and mobile transmitting node using VEINS simulator for VANET. Now if the sender is moved from a far off distance towards the receiver there is not much losses but if I modify the same with the sender being placed nearer to receiver and starts moving far away there is significant losses.
So my question is if the broadcast of signals vary with the environment or are there any specific parameters that define the broadcasting techniques for any given node.
I would like to broadcast a message... but want to stop a particular node receiving this broadcast message... is there any we to do this in run time... can we able to change a channel of a node or the RF power a node for a particular time in TinyOS
I am interest in a good text about the law protection of this type of rights in comparative law.
I am going to do a quasi-experimental cross sectional study that measures the effect of new broadcasts on the fear of death compared to psychological distance. The idea is to divide the participants into two groups of equal size. One group sees a montage of news items including: the Ukraine crisis, a Boko Haram attack and an oil crisis in Brazil. The second group gets the same video but instead of the Boko Haram item it will show an item about the recent Paris terrorist attacks. I am not sure how to effectively measure death anxiety in this case because I want to have a before and after the video result so we can see what effect the videos have on the fear of death. Could anyone help me out?
i work on deployment of AUVs to achieve coverage in UWSN
i need each AUV get position information of its neighbor to make decide for next move. I do not need routing protocol, just normally one node
broadcast packet and neigboring nodes receive that packet.
i didn't know how the node can send message that contains its position information to all of its neighbor?
Does anybody know of any case where any government/regime complained to the British government about the BBC broadcasting of any news/programmes, similar to governments complains to the Qataris about Al Jazeera's broadcasting some of its news/programmes?
Since 2001/2002, the Brazilian Supreme Court broadcast all it's judgements. The experience show us interesting situations, as judges laughing and teasing other judges (a.ex. Criminal Suit n. 470, in witch Justice Marco Aurélio called Justice Roberto Barroso "the beginner", then the newer Justice on the Court.
We aslo could see Justices discussing ideas disrespectfully, almost fighting, like when the Justice Nelson Jobim asked, on the Judgments of the Direct Unconstitutional Suit n. 2925, the follow question: "and the curious thing is that the Supreme Court is holding against the government of the Republic dishonesty, and for whom? National Confederation of Transport!".
In another judgment, the President of the Court, Justice Ricardo Lewandowsky did a public recognition of his own ignorance of a specific legal theory, one of the most famous and well-known legal theory of the country, saying he never heard that theory before, being interrupted with a laugh humorous by justices Gilmar Mendes and Luiz Fux, talking about the extensive discussion and knowledge of such theory.
In the same judgment (RE 608.482/RN) the Justice Roberto Barroso showed technically not know the difference between something important in the world of law, as the difference between trial injunction and judgment on the merits, and heard the Justice Teori Zavascky ask ironically: "then we'll start discussing process here, now?", and the Justice Marco Aurélio also Asked to call one of the most important Brazilian civil procedure professors, José Carlos Barbosa Moreira, to solve the question.
The live broadcast of the Judgements of Supreme Court trilas is a good thing, even when it show us the worst side of the Justice, as the bad side of the human being? Or it is a bad idea broadcast Supreme Court trials, because it brings some degree of loss of respectability for justice?
Concerns on interference of wind turbines and wind turbine parks on the distribution of RF broadcast signals, point-to-point radio links and radar are raised from time to time. The interference would be caused by scattering of the signals of the turbine blades, intermittent shadowing by the rotor blades and in a turbine park even by the number of large (forest) of vertical support structures. To avoid following unvalidated opinions I would like to collect as many scientific research articles on this issue as possible. Target frequencies are between 80 and 800 MHz, although other frequencies are welcome too. Any suggestions of titles and authors are very welcome!
Gannett Tuesday became the latest media company to separate its publishing assets, which include USA Today, from broadcast and digital businesses. The move is the latest in a string of similar actions by the likes of Time Warner TWX +2.24% and News Corp NWSA +0.85%., which have both separated slow-growing print segments from more profitable television divisions.
I need to see opinions from physicists and radio/TV broadcast engineers as to the possible explanation of a video signal being gradually interfered with until it vanishes on the receiving TV monitor. Total elapsed time is usually 20 to 30 minutes. Once the set-up is complete, there are no changes made to transmitting power or anything else. The signal is being transmitted through a rotating electromagnetic field. This experiment has been repeatedly conducted with the same results.
