Frequency modulation

Delta waves (0.5-4Hz) are a characteristic of deep sleep and are generally not present during meditation or relaxation. Theta waves (4-8Hz) are strongest in the frontal and middle parts of the brain during meditation and most likely show the relaxed attention that arises as we focus on our inner experiences. Frequent Theta waves are more likely to occur in highly experienced meditation practitioners. Alpha waves (8-13Hz) are present during relaxation, daydreaming and light meditation and…

Assignment 2 Data Communication- Net Centric Question 1 CDMA is what that have a several protocols that was used in the 2G and 3G wireless communication. CDMA is a service that provide all the communication overall and it also provide in major service in network capacity. CDMA service is mostly used in Cell phone and it can be easily be used for communicating terminal with two base stations. CDMA is a form of multiplexing, which allow a number of signals to work on a single transmission…

voltage source inverter (VSI). A.PULSE WIDTH MODULATION It is a commonly used technique for controlling power to inertial electrical devices, made practical by modern electronic power switches. The average value of voltage (and current) fed to the load is controlled by turning the switch between supply and load on and off at a fast pace. The longer the switch is on compared to the off periods, the higher power supplied to the load is. The PWM switching frequency has to be much faster than what…

The pencil grip is a low- tech assistive technology for children and adults who struggle with writing and correct pencil grip. The device can fit on pencils, pens, crayons and all writing tools and has been said to be “easy to use and comfortable”. The Pencil Grip increases comfort, teaches proper hand positioning, and improves control. Its ergonomic design also provides relief of hand fatigue and pain. Both right handed and left handed individuals can use it. Students place their fingers on…

electronics and communication engineering purposed by department of electronics and computer department of IOE, western regional campus, Lamachoor, pokhara. Mainly, project presents both hardware and software implementation for developing radio frequency based control mechanism via wireless transmission. The duration of the project was four months from September 2010 to December 2010. It was a group project with four members and was supervised by Er.Kamal chapagain. I was entirely involved in…

step up operation and then inversion. To increase the output ac voltage from a dc source, usage of a conventional voltage-source inverter (VSI) fed step up transformer can provide simple solution. In [2], a step-up transformer is utilized at line frequency to boost the voltage coming from inverter. However, this solution is suffering from several disadvantages, such as loud noise, high cost, high volume, bulk size, lesser power/weight ratio and relatively high cost. Furthermore, the transformer…

Our cognition processes information coming from different channels of sensory modalities and integrates it smoothly. In most of the time we are not even aware of the modalities of the information, rather all we are conscious of is the information itself. Having more senses provides more accuracy in different dimensions of an event such as time and space. For example, one sense is less accurate about carrying time dimension of an event, while other is less accurate about estimating the location.…

or users. Figure 1 www.mountnittany.org/articles/healthsheets/7126 “Differences between REM sleep and lucid dreaming were most prominent in the 40-Hz frequency band. The increase in 40-Hz power was especially strong at front-tolateral and frontal sites. These results suggest that 40-Hz activity holds a functional role in the modulation of conscious awareness across different conscious…

training, the adrenal cortex is then stimulated by ACTH to release cortisol. The short-term elevation in cortisol is a standard response, often resulting from training adaptions such as increased loads, varied intensity, extended training time and/or frequency, etc. These acute elevations reduce inflammation by suppressing the immune system, a frequent causative agent of inflammation, using a negative-feedback system. Cortisol, when released in an acute manner, improves the body’s catabolic…

As the social worker, I suggested client attend a support group for teen who are living with HIV. This will assist the client in becoming educated about the virus. This will allow the client to meet peers dealing with the same problem. Client may find a peer that she can relate too who contracted the disease in a similar manner as the client (i.e. rape, incest). This also will help the client not feel as if she is dealing with the Virus alone. For youth living with HIV, support groups also…
