As the time horizon increases, variable costs rely less on existing factors and restrictions and therefore will begin behaving differently which will in turn affect the cost of production (Wright, 2007). The second way a firm that’s into profit maximization can decide its greatest level of output is by way of the marginal revenue -- marginal cost method. This is done by subtracting the marginal cost from the marginal revenue that a product generates. Using marginal cost and marginal revenue as the bases, profit maximization will be obtained at the point when marginal revenue is equal to marginal cost. If the marginal revenue is greater than marginal cost this would be when a profit maximizing firm would need to increase production until marginal revenue is equal to marginal cost.
Data application. Fax Machines a device that scans and processes the contents (text or images) as a single fixed graphic image converting it into a bitmap, and then transmitting it through the telephone system. The fax machine reconverts the coded images, printing a paper copy. Before digital technology became widespread, the scanned data was transmitted as analogue. Pagers is wireless telecommunications devices that receives and displays numeric or text messages, or announces voice messages.
| Call Waiting | This allows you to know that there is someone calling you when you already using the phone. Usually this is indicated by a tone or lights flashing on the phone. | Caller display | Allows the user to see what type of call is coming into the phone (internal or external) and also the telephone number. This when used with a contact list or directory can allow you to see who is making
We make an Internal Representation (I/R) of thatevent. That I/R of the event combines with a physiology and creates a state. "State" refers to the internal emotional state of the individual – ahappy state, asad state, a motivated state, and so on. Our I/R includes our internal pictures,sounds and dialogue, and our feelings (for example, whether we feel motivated,challenged, pleased, excited, and so on). A given state is the result of thecombination of an internal representation and a physiology.
c) How does one nerve cell communicate with another? - Nerve cells communicate with one another through neurotransmitters. 2. a) Explain what neurotransmitters are? - Neurotransmitters are chemical messengers that cross the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing where that neuron will generate a neural impulse.
Rather the response to a stimulus “operates” on the environment and thus creates a different response when it affects the environment differently. (Hergenhahn & Olson, 2005). The relationship between a response and the consequent changes it produces is known as a reinforcement contingency. Skinner’s work has provided the basis for behavior analysts to understand behavior in terms of reinforcement contingencies. Reinforcers are stimuli which if made contingent on a behavior increase the probability of that behavior over time.
The net reaction is: This reaction has been studied extensively and occurs for a wide variety of ketones. In general, the halogenations of a ketone can be represented as follow: The main evidence for any mechanism is provided by kinetic studies to determine an experimental rate law. Following the rate law of chemical kinetics, the differential rate equation for the reaction could be written as follow: Where k = rate constant; a, b,c are the orders of the reaction of S, I3-, and H+ respectively. I3- ion is the only coloured species in the reaction mixture, a spectrophotometer can is used to measure the change in its concentration, by applying the Beer-Lambert Law Where A= absorbance, ε= molar absorption coefficient, [I3-]= concentration and /= optical path length, that is, the distance travelled by the light through the solution. The ideal wavelength for the measurement of
SENSATION Sensation is defined as the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment. The study of sensation is concerned with the initial contact between organisms and their physical environment. It focuses on describing the relationship between various forms of sensory stimulation (including electromagnetic, sound waves, pressure) and how these inputs are registered by our sense organs (eyes, ears, nose, tongue and skin). The process through which the senses pick up visual, auditory, and other sensory stimuli and transmit them to the brain; sensory information that has registered in the brain but has not been interpreted. Sensation is the process by which our senses gather information and send it to the brain.
Organization: Memory improves when events are related to each other. Time-Dependency: Memory fades with time. Interference: The cause of forgetting is competition among available memories, not the loss of memories from storage through decay or displacement. Cue-Dependency: Memory improves when the environment provides richly informative retrieval cues. Encoding Specificity (also known as Transfer-Appropriate Processing): Memory is best when information processed at the time of retrieval matches information processed at the time of encoding.
Six scales and four orientations are implemented to extract features from face images. The image filtering is performed in the frequency domain because it is faster compared with the spacial domain convolution. The optimum features are selected based on mutual information. If a feature vector is strongly different from other features, their mutual information will be large. The polar form of 2-D Log-Gabor filters in frequency domain is given by, H(f,θ)=exp{〖-[ln(f/f_0 ) ]〗^2/〖2[ln(σ_f/f_0 ) ]〗^ } exp{(-(θ-θ_0 )^2)/(2σ_θ^2 )} [10] where H( f, θ) is the frequency response function of the 2-D Log-Gabor filters, f and θ denote the frequency and the phase/angle of the filter, respectively, f0 is the filter’s center frequency and θ0 the filter’s direction.
