Agriculture is the most important activity in Indian economy. More than 40% of the population rely on farming to satisfy their basic amenities of life. Almost 40% of India’s geographical region is utilized for agriculture activity and still the contribution of agriculture sectors in the Indian GDP is very less. The current level of data collection is not sufficient and efficient. So we need to develop some techniques in agriculture so that we can improve our GDP as well as the yield. For this we can use sensor network technology that helps in obtaining data in real time mode. For example WSN (wireless sensor network) can be used in crop management by detecting wetness of leaves that data can be sent to farmer or decision maker.WSN can facilitate …show more content…
A major role is played by agriculture in providing large scale employment to the people, especially the villagers. Agricultural growth is considered necessary for development and for a country’s transmutation from a traditional to a modern economy and especially about India that is being well known for agricultural work. More than half of the workforce is related to the agriculture. Almost all the farmers are still depending on the traditional orthodox way of farming. It is being observed that the yield of crops, fruits , vegetables have not been increasing rather than they are declining in some parts of the country. Automation has been achieved; humans have been replaced by machines. But still crop yield has not increased upto optimum level. Directly speaking, science and technology has proved its importance in those fields. Therefore there is prime need to grab the prolifacy of science and technology in the field for higher crop yield and growth in agriculture. Greenhouse is the modern facility available developed by scientists in which we can control the climate to increase plant growth and avoid the effect of season changes on the …show more content…

1.1.3 RCA video out/audio Out
An RCA connector, sometimes called a phono connector or cinch connector, is a type of electrical connector commonly used to carry audio and video signals that’s why the connectors are also sometimes usually referred to as A/V jacks. It provides poor impedance matching. But it is commonly used as a connector for composite video signal.
1.1.4 JTAG Header
The 10-pin JTAG (Joint test expert group) header is a standard pinout JTAG connector. When we connect the Atmel AVR Dragon JTAG header to an external target, the signals are level converted to match the target board voltage. This is done automatically. The target needs to be powered through a dedicated power supply or by powering it using the VCC
3. Insulation material: made from XLPE and isolate between the three phases, its thickness is about 5.5 mm along the cable 4. Outer semiconductor: uniformly distribute the voltage on the surface of the insulation 5. Earth layer: made from copper, used to ground the cable, in case of short circuit it protect the cable by leaking the short circuit current into the ground, its thickness is about 25mm2 area 6. Filling: synthetic fibers used to make the cable circular and to fill the gap between the phases 7.
Measure the capacitance of the open-ended coaxial cable 3. Determine Ra and Rb to meet the amplitude and time constant specifications. 4. Measure the Gain and time constant (Tau), and compare the the measured data with the calculated data, which based on experiments. Instructions: 1.
However, this computer does connect to an external TV tuner over ethernet to record over-the-air signals. As indicated in the bulleted list above, the 250GB SATA drive is configured as the boot device, while the two 1TB drives are configured to store all important data, recordings, and DVD to MPEG compatible conversions. Although the 250GB drive is specified as a boot device in the BIOS, it is third in the boot order following USB boot devices, and CDROMs. This BIOS boot setting is configured to allow for an alternate boot up source, should the main boot drive fail, which is the current case. Since this computer is configured as an HTPC, all other BIOS settings provide no advantage and are set to
In half-duplex networks, the node transmitting must make sure that the network is quiet prior to transmitting, and in addition there is usually some mechanism for transmitting nodes to detect overlapping transmissions. 10BASE5 coaxial cable is the transmission technology used in the classic Ethernet protocol which was a stiff enough cable which was hard to install in buildings etc. as it was hard to bend. As it was hard to install along with other issues, 10BASE2 cable was made which was a skinnier coaxial cable which had obvious improvements in terms of installation.
This equates to approximately 100 connectors per aircraft that will have to be screened for the Amphenol defective insert issue.
Valid values are 0 to 8. data – Up to 64 bits of application data may be transmitted.
Once, the current rating and voltage rating are chosen, one needs to look at the data sheet of the connector to check whether it meets the given specifications. In the datasheet, one should look at the test procedure used to arrive at the specifications and check whether it meets the test standard. Not everyone uses the same testing criteria, so ensure you understand how these specifications were derived. It should also be confirmed that the contact will support the conductor size that has been chosen. A non-compatible conductor could cause overheating issues, leading to premature connector failure.
In telecommunications, RS-232 is the traditional name for a series of standards for serial binary single-ended data and control signals connecting between a DCE (Data Circuit-terminating Equipment) and a DTE (Data Terminal Equipment). It is use to connect the computer serial port to the electronics component like data storage, printers, mice, un-interruptible power supplies, and other peripheral devices. The standard defines the meaning of signals, the electrical characteristics and timing of signals, and pin out of connectors and the physical size. Figure 4.17: RS232 4.14 Motor
4 QoS Based Protocols QoS based protocols ensure sensor nodes balance between energy consumption and pre-determined QoS metrics like delay, energy, reliability and bandwidth, before delivering data to sink node. Sensor nodes have low processing capability, low memory power and limited transmission energy in addition to energy constraints. Hence the constraints impose an important requirement on wireless sensor network QoS support mechanisms including simplicity. Traffic flows from many sensor nodes to a small subset of sink nodes in most WSN applications. QoS mechanisms must be made for unbalanced QoS-constrained traffic.

4. In the book Lord of the Flies, written by William Golding, the conch was a symbol that brought forth both power and destruction. The conch is a valuable item at the beginning of the book that the boys believe holds most of the power.
These terms appeal to John’s sense of superiority. She wants her son to feel as though he is better than others, for him to gain the confidence he needs to “do honor to [his] country”. Through nationalism and patriotism, also, she stimulates her son into benefiting their country. She both wants to see her country succeed and her son to become powerful, thus benefiting her. Her son gaining great power and success will transfer onto her.
