Spread spectrum transmission is the process of spreading a signal across a certain frequency domain, giving the signal more bandwidth. This technique is important since it addresses concerns of security, jamming, noise, and natural interference. It also has a lower power requirement and is able to transmit more information than narrowband transmission. Spread spectrum transmission is accomplished by a modulation technique known as frequency hopping (FHSS). Frequency Hopping Spread Spectrum (FHSS) * What is it?
They are Amplitude modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM). These methods are based on altering one of the carrier’s characteristics: amplitude, frequency, or phase. In AM, FM and PM modulations each carrier changes in accordance with the information signal’s amplitude variations. When it comes to advantages and disadvantages there are performance factors to consider. They are spectral efficiency which identifies a communication system’s ability to achieve a given data rate within a given bandwidth.
Cortisol is sometimes referred to as a ‘stress hormone’ because it is produced in times of stress. The high levels of cortisol are not surprising as many depressive episodes are preceded by stressful events. Given this, the high levels of cortisol may be a result rather than a cause of depression – they may be produced as a response to stress rather than a cause of the disorder. The Biological Model states that psychological disorders are caused, at least in part, by biological factors. This suggests that treatment should

The text defines stress as: a. the negative emotional responses people experience when they are threatened b. the increased arousal people experience when they are threatened c. any environmental event that produces elevated heart rate and blood pressure d. the physical and psychological reactions people have to demanding situations __A__ 2. Hans Selye introduced the model of stress reaction called the general adaptation syndrome (GAS). Selye was convinced that reactions to stressful situations: a. were general and nonspecific b. differed, depending on the type of stressor that was present c. were stronger when people had other physical illnesses d. differed, depending on the personality characteristics of the individual __A__ 3.
A phrase of a waveform is the point where the wave is in its cycle. 2. What happens when two identical waves are in-phase? When two identical waves are in-phrase they build on one another, making higher amplitude. 3.
Sound shadow- creates high frequency sounds. Time of arrival-the difference of time arrival to the two ears and phase difference the phase difference between two ears provides cues to
The lateral nucleus is concerned with detecting the direction from which the sound is coming, presumably by simply comparing the difference in intensities of the sound reaching the two ears and sending an appropriate signal to the auditory cortex to estimate the direction. The medial superior olivary nucleus, however, has a specific mechanism for detecting the time lag between acoustical signals entering the two ears. This nucleus contains large numbers of neurons that have two major dendrites, one projecting to the right and the other to the left. The acoustical signal from the right ear impinges on the right dendrite, and the signal from the left ear impinges on the left dendrite.The intensity of excitation of each neuron is highly sensitive to a specific time lag between the two acoustical signals from the two ears.The neurons near one border of the nucleus respond maximally to a short time lag, while those near the opposite border respond to a long time lag; those in between respond to intermediate time lags. Thus, a spatial pattern of neuronal stimulation develops in the medial superior olivary nucleus, with sound from directly in front of the head stimulating one set of olivary neurons maximally and sounds from different side angles stimulating other sets of neurons on opposite sides.
However, priming introduces a fluid aspect to studies of cross-cultural usage of pronouns since specific context can induce favorability toward either collectivist or individualistic mindsets (Oyserman & Lee, 2008). This tendency to either segregate or connect appears to interact with interpersonal assessments. Perceived reasons for individual behaviors by members of individualistic cultures are more likely to result from judgments based on ascribed attributes or traits, while those made by members of interdependent cultures are more apt to incorporate contextual or situational elements (Church et al., 2006; Na & Kitayama, 2011). Perhaps one of the clearest examples of this dichotomy exists in Western academic traditions, which continue to be subject to European notions of separateness that have produced what Gusa (2010) describes as an
Emotional Intelligence SSCI-206 American InterContinental University June 24, 2012 Abstract This paper will cover the results and description of experience after taking a self-administered Emotional Intelligence (EI) test. An explanation of emotional intelligence, along with examples and theories regarding Emotional Intelligence. The importance of Emotional Intelligence and how this can be enhanced. Emotional Intelligence Emotional intelligence (EI) is ones ability to be control, perceive and evaluate emotions (Dictionary.com, 2012). It is felt that emotions contain information regarding the relationships in our lives and that when something good or bad happens we have
