Whispering- requires the vocal folds to come together but not completely so there is a space between the arytenoid cartilages (432)

Attack: The beginning of phonation by the bringing together (adduction) of the vocal folds (165)
1.Simultaneous Vocal Attacks- When the adduction of the vocal folds and the use of air from the respiratory system happen at the same time. (165)
2. Breathy Vocal Attack- When the use of air from the respiratory system happens before the adduction of the vocal folds (165)
3. Glottal Attack- When the vocal fold adduct before the air can be released from the vocal folds (165)

Termination of phonation- Happens when the vocal folds abduct and the flow of air is stopped (147)

Sustaining Phonation- Happens when the vocal folds say adducted allowing the air to flow through (168) …show more content…
Vibration how it's governed:
Vibration is governed by elasticity of the vocal folds, the stiffness of the vocal folds and the quality of the vocal folds (160)

Frequency- Determined by the number of times a vibration cycle is repeated in a specific amount of time (162)

Period- A measure of vibration from a start time to a finish time (162)

Opening Phase- The phase where the vocal folds are beginning to open (180)

Closing Phase- The phase where the vocal folds are beginning to close but not completely (180)

Closed Phase- The phase where the vocal folds are closed and there is no air escaping (180)

Myoelastic theory of phonation- The elasticity of the vocal folds allows them to keep their shape after being stretched as well as the use of the Bernoulli effect with reduced the air pressure (185)

Types of Muscular forces:

Pitch- The highest and lowest frequencies (198)

Average fundamental frequency- The Average sound range taken over a period of time (198)

Optimal Pitch- The range of sounds that any given person can make

...1. Capture driver’s image while driving continuously by using inbuilt camera of Smartphone. 2. OpenCV is used to track facial expression. 3. Track Driver’s face and expression including eyes and mouth, movement(head rotation),stress recognition tracking 4. If eyes are closed for some fraction of time, then alert driver by sounding the alarm device or using various different alerts. 5. If mouth is open for more time then yawning is detected and alert is raised. 6. Driver’s head rotation is used to detect distraction, system will generate alert after driver distraction and inattention detection. 7. If stress is detected from driver’s facial expression and speech recognition then alert is raised and system autodials emergency numbers. In this project we are going to develop and integrate various functionalities into single application. These functionalities are: 1. Driver fatigue detection by • Eye Tracking • Mouth Tracking • Speech recognition • Stress recognition • Head Rotation recognition(Gaze Tracking) 2. Traffic sign detection 3. Road traffic detection(Traffic Jam) 1. Eye Tracking: Eye tracking helps to detect whether driver is sleepy by detecting open and close state of eyes and blinking of eyes. It considers all constraint like wearing glasses, brightness and dark light conditions while detecting blinking of eyes. If closed eyes are detected for some given fraction of time then system will raise an alert. 2. Mouth Tracking: It tracks drowsy conditions i.e. yawning...

...Q10.1 Magnetic tapes provide sequential access so it has to start and stop and reverse the head direction to search for the data. While the disk is rotating continuously and it can provide random access of data so the read write operation is easier in disks than the magnetic tape. Read/Write operation in hard disk most hard disk consist of several coaxial platters, these platters continuously move around the axis. the collection of number of platters forms a cylinder the read/write head is over the surface the head traces a circle on the surface of the platter known as track and each track divided into sectors and each sector contains a block of data to read the data from the disk the read/write head is located over the track that hold the data the time required to reach the data called the seek time after located the track the read/write head moved to the beginning of the sector that time required for that called rotational latency after locating the sector the transfer of data takes place so the total time is the sum of these three times, but it is not the same as the disk speed so a buffering provided by the disk controller Read/Write operation in magnetic tape they are non-volatile storage used for the backup and they come into layouts Linear and Helical and provide the sequential access mechanism. The storage technique known as data streaming. In Linear format the data divide into horizontal tracks while the Helical format has diagonal tracks. Q10.3 a/ Number of sectors...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

But Best Practice dictates to move some of theese Flexible Single Master of Operation (FSMO) roles to seperate servers. If you only have one domain controller (not recommended), there is nothing to do since all roles must be on this server, but if you have multiple servers you should move some of theese roles on to more servers. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server. Recommended Best Practice setup of FSMO roles. Domain Controller #1 Place the two forest roles on this server. * Schema Master...
